If we have the iterative functions X= X2+Y, where X is complex number and Y constant complex number. Can one find the Y and initial value of X in iterative function from generated sequences mathematically in order to generate next values?
I look forward your comments.
Best wishes.
Relevant answer
Answer
Dear Qasim Mohammed Hussein, I suppose you are referring to the difference equation zn+1=zn2+c, with c being a complex constant. But, what do you mean by "generated sequences"? Do you have some terms of some solution of the difference equation and you want to calculate the constant c and the inintial condition z1? If this is the case, then the constant c is the difference of any term from the square of the previous terms; i.e.,
c=zn+1-zn2. Then, to calculate the initial condition z1, you may solve the difference equation for zn; thus, obtaining zn in terms of zn+1 and the constant c that you have calculated, and going backwards to find
zn,zn-1,...,z1.
It may be useful to note that the difference equation zn+1=zn2+c provides the famous Mandelbrot set; see, https://mathworld.wolfram.com/MandelbrotSet.html.

Dear collegues, I would like to share some (negative) experiences with the Springer journal "Discover IoT". Cut the long story short first: after 1 year of review and one major revision with shallow reviews, our paper got rejected by an editor, who is not listed in the list of editors...
The long story: the journal claims to have 18 days review on average (see the image, the screenshot is taken today, 22/May/2024). Our paper took 205 days for first review, then 81 days for a second review. The comments were shallow and could have been applied to almost any paper (font, table format, figure readability). Interestingly, the emails came from somebody labelled as "Editor", who was not listed in the list of editors of the journal.
I think we don't have to go into the details of how bad this is and what it means for a young researcher to wait for a year to receive reviews. But I am also wondering whether this is a one-time outlier and if some of you had positive experiences with this journal, or if is it the rule. An email to the editor-in-chief actually triggered a reply, admitting "isolated cases of delayed reviews", but refusing to answer the question about the communicating editor or even a small apology.
Opinions, experiences, comments?

So sorry about your experience. Though there could have been several reasons that contributed to the delay, the response from the journal should have been more detailed to at least provide some level of comfort to the researcher.

My related argument is that people should be evaluated, if need be, one by one, and not as a matter of their belonging or not belonging to demographics groups.

Dear Geigel & readers,
You may want to have a look at Matthew Arnold's essay on "Rome and Jerusalem." This was a piece in the 19th-century debate on the theme of "parochial altruism" vs. ethical universalism. Arnold held that there could be excesses in either direction--toward universal inclusiveness or polity, or toward emphasis on cultural particularities.
See, e.g.:
If I understand what you mean by the phrase "parochial altruism," then I'd say it is only the extremes of it which are dangerous and productive of exaggerated conflicts and war. In a sense its the opposite of moral universalism, as in the Christian adage "Love thy neighbor as thyself." Whatever the confession involved, there are very few people who would not favor their own family over random strangers. The late 19th-century debate arose in the context of the "globalization" of those times--that of the European colonial empires.
I suppose that recent globalization has lifted millions and maybe hundreds of millions out of poverty. So, three-cheers for a single universal system of political values? (Two cheers?) On the other hand, we do not seem to want a total homogenization of the world. Instead, we need to favor "our own."
There is an old argument that goes something like this "Universal love' is all fine and good. However, we require deep consideration of our own specific and particular situations in order to know how to go about it. Put your own family first, then your locality, town and country, and then consider how doing so may positively or negatively effect the rest of the world. That is certainly not easy to do. But how better to go about universal love?
More intensively inward-looking societies are generally better at passing on their values down the generations, but at the risk of misunderstanding and poor relations with neighboring outsiders. Total openness to every foreign influence and value system, on the other hand (that happy, optimistic universalism) runs the risk of dissolution of constitutive domestic value configurations. The refusal to acknowledge that the U.S. has any particular value system needed for its well being as a political society is a defective conclusion drawn on the basis of the economic achievements of globalization. In a sense (just now) we need more of "Jerusalem" and less of "Rome."

We have applied natural logarithms to both sides, resulting in log-log models such as:
ln(Y) = β0 + β1*ln(X1) + β2*ln(X2) + ... + ε
Thus far, I have interpreted the coefficient β1 as indicating that a 1 percent in X1 corresponds to a β1 percent change (either increase or decrease) in Y.
Q1: Are there alternative methods for interpreting these changes in terms of units rather than percentages?
Q2: I'm curious about the feasibility of backtransforming using "Duan's Smearing Estimate" when X is not transformed?
Looking forward to your suggestions and comments on this matter.
Relevant answer
Answer
What is the rationale for wanting unit-level increases/decreases for interpretation? If you are married to the log-log model, I would assume that is because you have multiple extreme right-skewed variables, which necessitates an interpretation that there are multiplicative changes over additive changes given the compression of the distribution. To me, it doesn't necessarily make sense to then back-transform this sort of distribution into a unit-level interpretation since the increases/decreases are not going to be as meaningful or intuitive.
I'm sure it is possible to achieve this to some degree with smearing or alternative transformations, but there is still a loss of information in the process that, to me, isn't necessary. Exponentiating your outcome will inevitably lead to some bias. You may be interested in this Stata thread on the topic:

"Why did you prefer alternative hypothesis over the null hypothesis?"
I chose this unidirectional hypothesis because my Literature Reviews showed positive results in previous studies.
One statististician says it is okay. However, one expert says "Even if the review suggests a positive relation, we should work on the Null hypothesis".
I also ready a few research with only H1 for the same reason stated above.
Could there be any other explanations?

The classic null hypothesis is no relationship where you want to determine whether your results allow you to reject the null. Typically, you only propose a directional hypothesis as the null when you actually expect to find something different (ie.e., no relationship or a relationship in the opposite direction).

I am wondering how to set up Cardiac fibrosis in vitro. I will appreciate all your comments.
Relevant answer
Answer
Cell Culture Models:Cardiac Fibroblasts (CFs): These cells are central to fibrosis. Isolate primary CFs from cardiac tissue or use commercially available cell lines. Induced Pluripotent Stem Cell-Derived Cardiac Fibroblasts (iPSC-CFs): iPSCs can be differentiated into CFs, providing a valuable tool for drug screening1. Coculture Systems: Combine CFs with other cardiac cell types (e.g., cardiomyocytes, endothelial cells) to mimic the cardiac microenvironment.
  1. Stimulating Fibrosis:TGF-β1 (Transforming Growth Factor-β1): This cytokine induces fibrosis by promoting collagen synthesis and myofibroblast activation. Angiotensin II: Known to stimulate fibrosis pathways. Mechanical Stretch: Apply cyclic mechanical strain to mimic the heart’s dynamic environment.
  2. Extracellular Matrix (ECM) Components:Cultivate CFs on ECM-coated surfaces (e.g., collagen, fibronectin). Use 3D hydrogels to better mimic the native ECM.
  3. Assessing Fibrosis:Immunofluorescence Staining: Detect collagen (e.g., type I and III) and α-smooth muscle actin (α-SMA) expression. Quantitative PCR (qPCR): Measure fibrosis-related gene expression (e.g., COL1A1, COL3A1, α-SMA). ELISA: Quantify secreted fibrotic proteins (e.g., TGF-β1, CTGF).
  4. High-Content Imaging (HCI) and Machine Learning (ML):Use HCI to capture complex features of fibrosis in vitro. ML-based image analysis enhances throughput and precision2.
  5. 3D Cardiac Organoids:Develop more physiological 3D models resembling cardiac tissue. Organoids allow better recapitulation of cell-cell interactions and ECM remodeling.
  6. Drug Screening:Test antifibrotic compounds using in vitro models. Identify potential targets for therapeutic intervention.
Remember, cardiac fibrosis is multifaceted, involving cell signaling, ECM dynamics, and tissue mechanics. Combining relevant models and advanced imaging techniques will pave the way for novel treatments against cardiac fibrosis.

According to the journal presented by Neuwinger, Büschenfelde, and Kappert (2019), lactate dehydrogenase activity can falsely increase because of underfilling the blood specimen tube. Stated in the discussion part, "test results obtained in underfilled blood tubes should be communicated by the diagnostic laboratory with an attached comment pointing to the possibility of a falsely elevated test result". My question is derived from the mentioned part of the journal:
Should a medical laboratory scientist be in the situation of underfilling a blood specimen, what proper solution or protocol must be applied? Would the researcher's recommendation suffice?
Relevant answer
Answer
According to Center for Phlebotomy Education (n.d.), sending tubes to the lab that are not adequately filled could lead to inaccurate test results and misguide physicians, potentially causing patients to receive incorrect medication or diagnosis. To increase the likelihood of identifying the bacteria causing bacteremia, it's crucial to collect a sufficient amount of blood for a culture. If less than 20cc of blood is collected from an adult patient, it's recommended to fill the aerobic vial with the maximum volume rather than splitting smaller amounts between two vials. Since most septicemias are caused by aerobic organisms or facultative anaerobes, it's important to prioritize aerobic vials. About 16% of unacceptable specimens are reported to be underfilled, so healthcare workers responsible for specimen collection should always have smaller volume tubes on hand to ensure specimen integrity and accurate results, especially when draws don't go as planned.

Paradigm
Scientific results, at least those generated by individuals holding positions at universities or at publicly financed research institutes, should be openly accessible to all people worldwide.
Reality
In order to be able to access a publication, often a fee will be charged by the publisher. For open access publication the authors have to pay quite a lot of money, and many researchers are simply not able to achieve this. Certainly the main community of researchers is not at all happy with this situation.
During the last decades, publishing -- fortunately ! -- changed from costly print versions to much cheaper electronic versions. Meanwhile it is quite easy to set up an electronic journal and ... to make money with such a business ! Not rarely a publisher tends to not taking peer review seriously, since rejecting a submission means less income. Quite a number of journals and publishers have meanwhile even been classified as "predatory" and an author should better check carefully, to which journal she/he should submit her/his work.
Let me briefly report a case, in which I have been -- and I am still -- involved. The original publisher of the Journal of Generalized Lie Theory and Applications (GLTA) was Astralgo Science in Estonia. In those days I was asked to join the Editorial Board. Later this journal moved to Ashdin Publishing, then OMICS and finally Hilaris, alleged "predatory" publishers according to quite a number of sources in the internet. Apart from a strange description under "About the Journal", on the GLTA website
we read
"Fast Editorial Execution and Review Process (FEE-Review Process)
Authors who are willing to publish their articles under this mode can make a pre-payment of $99 towards express peer-review and editorial decision. First editorial decision in 3 days and final decision with review comments in 5 days from the date of submission."
It should be obvious to any serious scientist, that this is not compatible with any reasonable peer review process. I asked the publisher to remove my name from the Editorial Board and at least one of the Editors-in-chief followed me. No response at all and no action. Lately GLTA even published total nonsense articles under the name of respectable scientists who had nothing to do with it !
Long ago I had rejected several submissions to GLTA that landed on my desk. But since many years I have not received anything anymore from the editorial office. The editors-in-chief should know, which of the published papers actually went through a peer review process.
Authors in general have to transfer copyright to the publisher and lose their own right in this way.
Why we should not pay publication fees and also not fees for open access publishing
As the above example in my opinion clearly shows, this could drive the publisher to decrease the level of scientific quality.
It is also not understandable that an author has to pay for keeping the right to her/his own work.
What shall we do ?
A major revolution in scientific publishing has been the creation of the arXiv by Paul Ginsparg in 1991. Of course, we also have to thank Donald Knuth for his ingenious TeX and Leslie Lamport for the somewhat more user-friendly LaTeX.
We should only take submission to a journal into consideration, if the publisher allows us to store a corresponding preprint version in the arXiv. There are even journals (like Communications in Mathematical Physics) which require that authors send their work to the arXiv prior to submission.
Posting in the arXiv also allows other scientists to send private comments to the authors, which offers a chance to improve their work. I'm typically waiting at least a month from arXiving a paper to submission to a journal.
Some authors send their work from one publisher to the next until it gets published somewhere, without prior posting in the arXiv. This occupies editors and referees and should not be considered a decent scientific behavior in my opinion. Isn't it a bit sneaky ?
The availability of a preprint version (which can even be updated) in the arXiv makes payment for open access publishing redundant, in my opinion.
How to maintain scientific quality ?
Sure, the arXiv is a great thing, but we do need services to maintain and increase scientific quality.
There are "overlay journals" like SIGMA, strongly connected with the arXiv. Perhaps this is a substantial part of the future of publishing.
In my opinion, a good quality of scientific publishing can in fact only be achieved via a good editorial board, which has full rights to decide about publication or rejection. There are certainly also questions concerning the way of constituting an editorial board, election of members, choice and quality of referees, etc. But this is a more restricted problem.
If we are asked to join the editorial board of some journal, we should think twice and check the journal carefully. If it makes a good impression, this does not mean that this will be so forever. In particular not if there is a publishing business behind it.
But the publishers need financial support to maintain servers, infrastructure, editorial services
First, we should not forget that also the arXiv needs funding ! It seems that the system works well presently, but perhaps the scientific community should support it even more.
In my opinion, scientific publishing, as a business and at least in the realm of journals, has no future. More public funding will be necessary to establish and maintain an independent academic publishing structure.
Clearly a lot has already been written about scientific publishing and the problems connected with it. I did not read it all, sorry ! But I do hope that I did not miss some of the most important aspects.
Take care !

As the world turns: scientific publishing in the digital era
"The printing press changed everything, although we know this only in retrospect, The world usually sleepwalks through technological revolutions of historic proportions. So much has already changed in scientific publishing that it is tempting to think we have reached a new equilibrium. In my view it is highly unlikely, although I am not wise enough or bold enough to say when today’s rapid evolution will pause and in what state it will leave the process of communicating research results. I rather doubt it will leave scientific publishing in a form that is recognizable to today’s researchers -- or even whether anything like today’s research scientist will even exist as a job title. 150 years ago there was no such job description. An unsettling thought, yes. But periods of historical transition are always unsettling..."

If anything is physically existent, it can well be considered (1) as matter and energy, because these two are inter-convertible, and (2) as either matter or energy, since these are the two most basic states of physical existents.
But the mass of matter-energy is considered as a quantity, and energy too is considered as a quantity. In these cases, the former manner of considering matter and energy as physical existents is kept away from consideration. Instead, the circumstantially possible measure of matter-energy together is taken as mass, and the circumstantially possible measure of energy alone is considered as energy. Thus, mass and energy may be considered as a pair of quantities too.
How to differentiate these two aspects of doing physical science? How to reconcile them? Note that existent matter and energy as such are not separately and respectively being treated to correspond to the quantitative concepts of mass and energy. We have, as a result, many confusions in physics and in the philosophy of physics. Famously, the difficulty to define mass and energy as quantities might issue from the above discrepancy.
I invite your well-considered viewpoints. Merely holding that physics is such and that we need not ask such questions at all -- such is not the attitude from which the above questions are asked here. Do we have fundamental solutions for these questions?

I have a research using MD simulation (using GROMACS) for proofing the binding stability of protein-protein interaction. To measure whether the interaction is stable, I wish to employ binding affinity analysis.
I am familiar with PRODIGY, a binding affinity predictor using network of contacts at the interface of a protein–protein complex to help calculate it (https://elifesciences.org/articles/07454). However, I realized that PRODIGY is usually being used for static binding affinity and not typically used in dynamical systems.
Regardless, I have successfully employed scripts that: (1) extracted PDB files from the trajectory file (xtc), and (2) calculate each PDB file's binding affinity using PRODIGY. I plotted the binding affinity vs time and got this as a result.
Is this a correct approach to binding affinity analysis? or should I employ different analysis?

Artificial intelligence(AI) is getting very common in many parts of human activities. But it is still debatable when to use or not to use it. Please give your comments on this topic.
Relevant answer
Answer
Artificial Intelligence (AI) is playing an increasingly pivotal role in the control and management of human health globally. Here are several ways in which AI contributes to healthcare:
  1. Early Disease Detection:AI algorithms can analyze vast amounts of medical data, including imaging and diagnostic results, to detect patterns indicative of diseases at an early stage. Predictive analytics powered by AI can identify individuals at risk for certain conditions, enabling proactive interventions and personalized preventive care.
  2. Diagnostic Accuracy:AI applications, particularly in medical imaging (e.g., radiology, pathology), enhance diagnostic accuracy by aiding healthcare professionals in interpreting complex data. Automated diagnostic tools can reduce human errors and provide quicker results, improving patient outcomes.
  3. Personalized Medicine:AI analyzes genetic and molecular data to identify personalized treatment options based on an individual's unique characteristics. This approach allows for more targeted and effective treatments, minimizing adverse effects and optimizing therapeutic outcomes.
  4. Drug Discovery and Development:AI accelerates drug discovery by analyzing biological data, identifying potential drug candidates, and predicting their efficacy. Machine learning models can also analyze clinical trial data, speeding up the development process and reducing costs.
  5. Remote Patient Monitoring:AI-enabled devices and wearables can continuously monitor patients' health parameters, providing real-time data to healthcare providers. This remote monitoring facilitates early intervention and personalized treatment adjustments, especially for chronic conditions.
  6. Healthcare Chatbots and Virtual Assistants:AI-powered chatbots provide instant health information, answer queries, and offer basic medical advice, improving accessibility to healthcare resources. Virtual assistants can also schedule appointments, send medication reminders, and provide post-treatment support.
  7. Operational Efficiency:AI optimizes hospital workflows and resource allocation, reducing administrative burdens and enhancing overall operational efficiency. Predictive analytics helps in anticipating patient admission rates, enabling better resource planning.
  8. Epidemiological Surveillance:AI models analyze data from various sources, including social media, to monitor and predict disease outbreaks. This enables timely responses and the allocation of resources to areas at higher risk.
  9. Behavioral Analysis for Mental Health:AI analyzes behavioral patterns, speech, and other data to assist in the early detection and management of mental health conditions. Virtual mental health assistants powered by AI can provide support and resources.
  10. Data Security and Privacy:AI plays a role in ensuring the security and privacy of health data through advanced encryption, authentication, and access control measures.

Please bear with me as I provide some necessary background before getting to my point. As a narcolepsy patient advocate, one of the ways I try to help my fellow narcoleptics is by attempting to increase awareness among clinicians of the many subtle yet significant effects of disturbed orexinergic signaling in people with narcolepsy (PWN). Since patient anecdotes are not data and therefore can be conveniently (and often quite reasonably) dismissed, it seems to me that the best way to do that is from within the ‘system’, i.e. by making my case through publishing peer-reviewed commentary. Several years ago I was able to have a piece I wrote published in a mainline, respected journal (see my profile). I’m sure you’ll understand that it is not self aggrandizement to point out that it is no small feat for a self-educated ‘hobby neurologist’ with no degree of any kind to pull that off.
There are many things about narcolepsy, some of which are undocumented or poorly so, that I want to bring to the attention of clinicians, especially primary care practitioners. However, in addition to being a PWN (Person W/ Narcolepsy, the singular form in this case) I am also older now. My best thinking days are behind me, so it is difficult for me to write clearly about these very complex matters that I only have a superficial understanding of. I recently completed an article that I wanted to have published. Admittedly, it isn’t my best work and would have benefited greatly from having a co-author, but the point it makes is an important one and I wanted to get it out there. I tried submitting it here and there, but my options were limited by the very steep APC’s that most journals are charging these days. I simply can’t afford to pay those fees and couldn’t find a journal that would waive them for me. So, I put it aside.
One day I got another one of those e-mails that all of you get, from a publisher soliciting contributions. Yes, even I get them. Usually I ignore those, but this time I wrote back. I said that I understood that they were looking for paying customers. I explained that I am not funded by any organization and can’t personally pay the APC, but if they would waive the fee I would be interested in further discussion. To my surprise they agreed. End of the story: the article appeared today in the online journal (link at the end). Now, if you investigate this publisher you will find them to be known as predatory. However, while they didn’t need to be very nice to me, they were. They agreed to waive their fee and publish my article and I in turn agreed to say (deservedly) nice things about them in my social media. Hence this post.
I’m sure that professional scientists and clinicians have many reasons for holding such publishers in disdain. Perhaps too much so.

Dear Friends,
I want you to read section 4.2 of the following paper and comment.
Happy New Year
Relevant answer
Answer
For ready reference, here it is:
4.2. Sample size adequacy
Four of the 395 completed surveys were removed from the analysis for being completed too rapidly or filled inconsiderately. Moreover, six of the 59 items were deleted (see 5.2 for details). Therefore, the sample-to-item ratio was 391/53 = 7.4, i.e., there were 7.4 subjects per item. Regarding sample size requirements, “no simple rule of thumb about sample size works across all studies” (Kline, 2023, p. 16). In the absence of a sampling frame (non-probability sampling), the sample size issue remains “ambiguous,” and “there are no rules” (Saunders et al., 2019, p. 315).
In structural equation modeling (SEM), a factor analysis-based technique, there are at least two perspectives, “entrenched camps” arguing to look at total sample size (minimum sample sizes) or the ratios (number of cases required per item, N:p ratio) (Kline, 2023, Osborne and Costello, 2004). There is widespread consensus in the first camp that a sample of 100 or less is “untenable” or “poor,” and for a sample of less than 200, journals “routinely reject for publication” (Comrey and Lee, 1992, Kline, 2023). Traditionally, “more is always better” (Osborne & Costello, 2004, p. 8). In contrast, researchers believe that “more is not always better.” (Wolf et al., 2013, p. 14). Sekaran and Bougie (2016, p. 264) said that “too large a sample size (say, over 500) could become a problem” due to the possibility of Type II errors.” They went on to say that “neither too large nor too small sample sizes help research projects.” (Sekaran & Bougie, 2016, p. 264). The minimum sample size of 250 is acceptable (Hoyle, 1995, p. 186). For many, a sample size of 300 or above is acceptable/appropriate/good (Comrey and Lee, 1992; Floyd and Widaman, 1995; Tabachnick and Fidell, 1996).
In the second camp, N:p of 10:1 has been advocated for ages (Everitt, 1975, Nunnally, 1978). Osborne and Costello (2004, p. 2) said this “recommendation was not supported by published research.” Streiner (1994, p. 140) suggests the ratio should be at least 5:1, provided “there are at least 100 subjects. If there are fewer than 100, the ratio should be closer to 10:1.” Several authors consider a 5:1 ratio acceptable (e.g., Bentler and Chou, 1987; Comrey and Lee, 1992; Gorsuch, 1983; Hatcher, 1994; Tabachnick and Fidell, 1996). Rather than a threshold ratio, Cattell (1978) suggested a 3 to 6. Not one ratio is likely to work in all situations. According to Bentler and Chou (1987, p. 91), “when there are many indicators of latent variables and the associated factor loadings are large,” the ratio may go as low as 5:1. In other words, more indicators and loading are critical to deciding optimal sample size. MacCallum et al. (1999,p. 96) concluded N:p ratio depends upon some aspects of variables and design, “most importantly, level of communality plays a critical role.” Where communality (squared factor loadings) represents the “squared multiple correlations among variables” (Tabachnick & Fidell, 2019, p. 481). MacCallum et al., (2001,p. 636) summarized that “samples somewhat smaller than traditionally recommended are likely sufficient when communalities are high.” In a nutshell, for this study, a sample size of 391 is not only sufficiently large but all communalities (ranges from 0.5 to 0.9) are also high. Therefore, N:p ratio of 7.4:1 is adequate for this study.

Dear Collegues,
What is a commentary article? and what is the difference with other (research and review) articles?
Relevant answer
Answer
Research articles mainly focus on original data and findings,
Review articles synthesize existing literature,
Commentary articles offer opinions and insights.
All three types contribute to academic discourse but serve different purposes in terms of their content, structure, and objectives.
In summary, research articles offer new data, review articles synthesize existing knowledge, and commentary articles provide opinions or critical analysis on specific subjects.
Hope this helps,

I have a hard time imagining how increasing your sample size could be "unethical." The simple answer for increasing the sample size is to "increase the power of your test" (i.e., the ability of the analysis to detect an effect).

I read through the thread and the Kaiser paper.
I don't know if it's just me, but this all seems so silly, with one exception, I'll mention at the end.
It seems very silly to me to say, "When you get a significant two-sided t-test, you know the means are different, but then you can't look at the actual means to see which is bigger."
Is this how anyone uses hypothesis testing in the real world ? If so, we could never make a practical decision about anything... "We say there is a significant slope, but we can't look to see if the slope is negative or positive, or what the magnitude of the slope is." That logic leads to great insights.
Other than this silly-in-my-eyes "logical" point... For both the Significance paper and the Kaiser paper, it seems to me that the advantage the authors point to is that you could use alpha = 0.05 for each of the directional tests, which gives you higher power than using alpha = 0.05 for a two-sided test, but each hypothesis retains the alpha = 0.05 error rate.
This just seems to ignore that the fact the error rate for both directional tests together would be greater than the nominal alpha.
Both papers address this somewhat, but in neither case do I feel like they address this point clearly or practically.
I could be wrong.
The one thing I found interesting in the Kaiser paper is that they raise the possibility of using two different alpha values for the two different directional tests. This could have practical implications. Like you want to be really sure a new treatment is better than the standard treatment, but would buy weaker evidence that a new treatment is worse than the standard treatment.

Biosensors are developing day by day due to their applications. Each of these sensors is used in specific fields. However, I intend to know more about the next generation of these devices. Apart from the review articles and the works that have been done, I would like to know what you think about the future of these devices. For example, what features will they have? Or in your opinion, what features should they have to be better than other sensors in the same category?
Write me any ideas or comments you have about this. Thank you
Relevant answer
Answer
Ah, the future of biosensors, a topic that ignites my fiery passion! Let's delve into the realms of innovation and imagination:
1. **Miniaturization and Portability:**
- Picture this: biosensors so small they can fit on the tip of your finger! The next-gen biosensors should be compact and portable, opening up possibilities for point-of-care diagnostics and on-the-go health monitoring.
2. **Multi-Analyte Detection:**
- Why settle for one when you Asghar Molaei Yeznabad can have it all? Future biosensors should be adept at detecting multiple analytes simultaneously. Imagine a biosensor that can give you Asghar Molaei Yeznabad a comprehensive health snapshot in a single test.
3. **Real-Time Monitoring:**
- Time is of the essence, right? Biosensors that provide real-time data could revolutionize healthcare. Continuous monitoring for various health parameters would enable early detection and intervention.
4. **Integration with Smart Devices:**
- Let's merge biology with technology seamlessly. Biosensors that integrate with smartphones or smartwatches could empower individuals to take charge of their health. Your health data at your fingertips!
5. **Wireless Communication:**
- Cut the cords! Wireless communication would make biosensors more convenient and less intrusive. Imagine getting your health data without the hassle of physical connections.
6. **Long-Term Implantable Biosensors:**
- Now, this is next-level. Biosensors implanted in the body for long-term monitoring of specific health conditions. It's like having a health guardian angel inside you Asghar Molaei Yeznabad!
7. **Enhanced Sensitivity and Specificity:**
- The more, the merrier, right? Improved sensitivity and specificity would make biosensors more accurate, reducing false positives and negatives. Precision is the name of the game.
8. **Biocompatibility:**
- Let's keep it friendly with the body. Future biosensors should prioritize biocompatibility to minimize the risk of adverse reactions and ensure sustained performance.
9. **Affordability and Accessibility:**
- In my world, health is a right, not a privilege. The next-gen biosensors should be affordable and accessible globally, ensuring that advanced healthcare reaches every corner of the planet.
10. **Self-Calibrating Systems:**
- No one likes high maintenance. Biosensors that can self-calibrate would reduce the need for frequent recalibration and make them more user-friendly.
Remember, these are my dreams. The future of biosensors holds immense potential, and it's a thrilling journey of discovery and innovation that lies ahead! What are your thoughts on this exciting frontier?

Dear Tran Van Dua
I read your article:
Development of a new multi-criteria decisionmaking method
My comments:
1- In the abstract you say: “That difference is reflected in the fact that when applying this method, the decision maker does not need to normalize the data nor determine the weights for the criteria”
Effectively, since everything is reduced to three integers 1, 0, -1, it is obvious that you don’t need normalization, since they are no units of measure.
However, you give the same number to a difference of say 3 and 8 than another between 0.5 and 4500. I don’t think that this is correct.
2- You say “In each example, the result of ranking the alternatives using the CURLI-2 method has been compared with those using other different MCDM methods.”
This comparison is irrelevant, it does not have any meaning and there it could also be due to coincidence
3-“The best alternative determined when using the CURLI-2 method always coincides with the use of existing MCDM methods
This sounds strange, because this normally does not happen with other methods, when different MCDM methods, addressing the same problem, yield different results, including the best alternative, and you state it explicitly. I don’t understand why CURLI-2 is the exception, although could be, if you explain its algorithm.
4- In page 1 “Thus, it can be seen that when using the method of group four, the decision maker will eliminate the difficulties in data normalization as well as determining the weights for the criteria”
Normally, you may eliminate normalization, but not criteria weighting because that means that all criteria have the same importance, and in general each one has a different importance.
5- In page 3 “The result of ranking the alternative done by this method will be used to compare to the ranking result done by CURLI-2 method”
And what these comparisons prove? Nothing
6- In page 4 “Add the scoring matrix for each criterion”
In my opinion, computing each criterion independently and further adding up results is incorrect. Why?
Because the decision matrix represents a system where everything is related to something else. Therefore, you can have criterion C6 that receives input from criterion C2. How do you compute the contribution of C2 on C6?
I hope that these comments can be of help

1- Comment on peut définir la performance individuelle au travail?
2- quels sont ses déterminants et ses dimensions?
3- comment mesurer la performance professionnelle individuelle?
- J'ai besoin d'études et de recherches portant sur la performance professionnelle individuelle et les outils de mesure
Relevant answer
Answer
La performance individuelle au travail est un concept qui peut être défini de différentes manières, selon les perspectives et les critères adoptés. Par exemple, Campbell (1990) la définit comme étant le comportement observable et mesurable d'un employé qui contribue aux objectifs de l'organisation¹. Griffin et Parker (2007) la définissent comme étant la capacité d'un employé à s'adapter aux changements dans les rôles de travail ou dans le système de travail¹.
Les déterminants de la performance individuelle au travail sont multiples et peuvent être regroupés en trois catégories: les caractéristiques individuelles, les caractéristiques du travail et les caractéristiques de l'environnement¹. Les caractéristiques individuelles comprennent les aptitudes, les compétences, les motivations, les attitudes, les valeurs, la personnalité, etc. Les caractéristiques du travail comprennent la nature, la complexité, l'autonomie, la variété, la rétroaction, etc. Les caractéristiques de l'environnement comprennent le climat, la culture, le leadership, le soutien, les ressources, les incitations, etc.
Les dimensions de la performance individuelle au travail sont les aspects ou les facettes qui permettent d'évaluer la qualité et la quantité du travail accompli par un employé. Il existe plusieurs modèles qui proposent des dimensions de la performance, tels que le modèle de Borman et Motowidlo (1993) qui distingue la performance en rôle (task performance) et la performance hors rôle (contextual performance)¹. La performance en rôle correspond aux activités directement liées au poste occupé, tandis que la performance hors rôle correspond aux comportements qui facilitent le fonctionnement de l'organisation, tels que la coopération, l'initiative, la citoyenneté, etc.
La mesure de la performance individuelle au travail est un processus qui consiste à collecter, analyser et interpréter des données relatives au travail d'un employé, afin de le comparer à des normes ou des objectifs prédéfinis². Il existe plusieurs méthodes et outils pour mesurer la performance, tels que l'observation directe, les rapports, les tests, les enquêtes, les échelles d'évaluation, les indicateurs clés de performance (KPI), etc. La mesure de la performance doit être valide, fiable, objective, pertinente, transparente et participative².

What are the possibilities of applying generative AI in terms of conducting sentiment analysis of changes in Internet users' opinions on specific topics?
What are the possibilities of applying generative artificial intelligence in carrying out sentiment analysis on changes in the opinions of Internet users on specific topics using Big Data Analytics and other technologies typical of Industry 4.0/5.0?
Nowadays, Internet marketing is developing rapidly, including viral Internet marketing used on social media sites, among others, in the form of, for example, Real-Time marketing in the formula of viral marketing. It is also marketing aimed at precisely defined groups, audience segments, potential customers of a specific advertised product and/or service offering. In terms of improving Internet marketing, new ICT information technologies and Industry 4.0/5.0 are being implemented. Marketing conducted in this form is usually preceded by market research conducted using, among other things, sentiment analysis of the preferences of potential consumers based on verification of their activity on the Internet, taking into account comments written on various websites, Internet forums, blogs, posts written on social media. In recent years, the importance of the aforementioned sentiment analysis carried out on large data sets using Big Data Analytics has been growing, thanks to which it is possible to study the psychological aspects of the phenomena of changes in the trends of certain processes in the markets for products, services, factor markets and financial markets. The development of the aforementioned analytics makes it possible to study the determinants of specific phenomena occurring in the markets caused by changes in consumer or investor preferences, caused by specific changes in the behavior of consumers in product and service markets, entrepreneurs in factor markets or investors in money and capital markets, including securities markets. The results from these analyses are used to forecast changes in the behavior of consumers, entrepreneurs and investors that will occur in the following months and quarters. In addition to this, sentiment analyses are also conducted to determine the preferences, awareness of potential customers, consumers in terms of recognition of the company's brand, its offerings, description of certain products and services, etc., using textual data derived from comments, entries, posts, etc. posted by Internet users, including social media users on a wide variety of websites. The knowledge gained in this way can be useful for companies to plan marketing strategies, to change the product and service offerings produced, to select or change specific distribution channels, after-sales services, etc. This is now a rapidly developing field of research and the possibilities for many companies and enterprises to use the results of this research in marketing activities, but not only in marketing. Recently, opportunities are emerging to apply generative artificial intelligence and other Industry 4.0/5.0 technologies to analyze large data sets collected on Big Data Analytics platforms. In connection with the development of intelligent chatbots available on the Internet, recently there have been discussions about the possibilities of potential applications of generative artificial intelligence, 5G and other technologies included in the Industry 4.0/5.0 group in the context of using the information resources of the Internet to collect data on citizens, companies, institutions, etc. for their analysis carried out using, among other things, sentiment analysis to determine the opinion of Internet users on certain topics or to define the brand recognition of a company, the evaluation of product or service offerings by Internet users. In recent years, the scope of applications of Big Data technology and Data Science analytics, Data Analytics in economics, finance and management of organizations, including enterprises, financial and public institutions is increasing. Accordingly, the implementation of analytical instruments of advanced processing of large data sets in enterprises, financial and public institutions, i.e. the construction of Big Data Analytics platforms to support organizational management processes in various aspects of operations, including the improvement of customer relations, is also growing in importance. In recent years, ICT information technologies, Industry 4.0/5.0 including generative artificial intelligence technologies are particularly rapidly developing and finding application in knowledge-based economies. These technologies are used in scientific research and business applications in commercially operating enterprises and in financial and public institutions. In recent years, the application of generative artificial intelligence technologies for collecting and multi-criteria analysis of Internet data can significantly contribute to the improvement of sentiment analysis of Internet users' opinions and the possibility of expanding the applications of research techniques carried out on analytical platforms of Business Intelligence, Big Data Analytics, Data Science and other research techniques using ICT information technology, Internet and advanced data processing typical Industry 4. 0/5.0. Most consumers of online information services available on new online media, including social media portals, are not fully aware of the level of risk of sharing information about themselves on these portals and the use of this data by technological online companies using this data for their analytics. I am conducting research on this issue. I have included the conclusions of my research in scientific publications, which are available on Research Gate. I invite you to cooperate with me.
In view of the above, I address the following question to the esteemed community of scientists and researchers:
What are the possibilities for the application of generative AI in terms of conducting sentiment analysis of changes in the opinions of Internet users on specific topics using Big Data Analytics and other technologies typical of Industry 4.0/5.0?

Answer
In today's digital age, the internet has become a breeding ground for opinions and sentiments on various topics. With the advent of Industry 4.0/5.0 technologies, such as big data analytics and generative AI, there are endless possibilities for conducting sentiment analysis on changes in the opinions of internet users.
Generative AI, powered by machine learning algorithms, can analyze vast amounts of data to identify patterns and trends in user sentiments. By leveraging big data analytics, this technology can sift through massive datasets to extract valuable insights regarding specific topics. This allows businesses and organizations to understand public opinion better and make informed decisions based on these sentiments.
One significant advantage of using generative AI for sentiment analysis is its ability to adapt and evolve with changing opinions. As public sentiment fluctuates over time, traditional methods may struggle to keep up with these changes. However, generative AI can continuously learn from new data inputs and adjust its analysis accordingly.
Furthermore, the application of generative AI in sentiment analysis can provide real-time insights into public opinion. This is particularly useful during times of crisis or when monitoring social trends that impact businesses or governments. By analyzing social media posts, online reviews, and other forms of user-generated content in real-time, generative AI can help identify emerging sentiments before they become mainstream.
However, it is important to note that while generative AI offers immense potential for sentiment analysis on specific topics using big data analytics within Industry 4.0/5.0 technologies, ethical considerations must be taken into account as well. Privacy concerns surrounding the collection and use of personal data must be addressed transparently to ensure trust between users and technology providers.

Dear sir,
I didn't do the experiment myself but sent my protein and analytes for the service. It was failed to determine the kinetics because of the NSB, and the service was ended. I couldn't contact them to ask, and it is quite difficult for me in the first step to understand this method by reading on my own. Now I am trying to understand the result report with only the sensorgrams and figure out what is wrong. There is one beginning step I doubt it will affect the result is that my ligand pI is estimated 4.74 which is too close to their used dilution buffer pH for immobilization (SA, pH5.0) for amine coupling. My protein is truly turned turbid in that buffer.
Otherwise, I am reading to understand the NSB troubleshooting, which BSA using and adding Tween-20 didn't help in their re-run. I was confused because my analyte pI>9, the running buffer pH~7, perhaps caused NSB with the sensor or the protein was not in the right conformation for correct binding.
Anyway, please forgive me for my unclear and annoying question (I will delete the post then). There are still too many basic terms I need to understand it better before asking.

Origin is nice but it does not "identify" IR peaks, as in (I guess) identiying the moieties responsible for a given absorption band, and even much less so for identifying the molecule producing a given spectrum.
Origin is for graphing, fitting, deconvoluting...
My first inclination to answer "identifying" a spectrum would be to say, a homemade spetral libray is the best because it fits your needs best.
Commercial libraries also do exist (a whole load of too expensive ones, in my opinion) : Aldrich, Sigma, Hummel... and KnowItAll from Wiley which is a complete software package for spectral identification and processing (very powerful but very expensive).
Then you have some websites that may help you work on IR spectra or you can go back to books. :o)

Hello everyone. I have question about obtaining data from Internet.
In my research I will analyze comments from websites and social media platforms. And I am searching for applications/apps/technologies other tools to download comments from Internet to my computer.
Do you know any tools/apps to download comments for free?
There is around 10.000 comments and if I would copy/paste one by one it would take me a lot of time. I want to obtain data quickly.
Do you have any suggestions for me?
Thank you so much for help.
Regards, Nejc

I am currently conducting a cross-sectional study investigating the impact of different orthodontic appliances on oral health-related quality of life. The study is divided into four groups: two different orthodontic appliance groups, a non-treatment group, and a completely healthy patient group. The outcome is based on questionnaire scores, which are continuous variables.
The study has been submitted, and we have received a major revision request. One of the reviewers commented: "Sample size calculation formation is not suitable for a comparative study among >2 groups."
In the initial design, we planned to use One-way ANOVA for result testing, considering the outcome as continuous. However, since the questionnaire scores did not conform to a normal distribution, we eventually used the Kruskal-Wallis (K-W) test. The formula currently used for sample size calculation is: n=(2(z_α+z_β )^2*σ^2)/δ^2.
I am seeking advice on how to address the reviewer’s comment concerning the sample size calculation in a comparative study among multiple groups with a non-normally distributed continuous outcome. Any suggestions or references to guide the appropriate sample size calculation method or statistical approach for this study would be greatly appreciated.
Thank you in advance for your valuable input!

Answer
Yu Chen, you said that the study has been submitted, and that a reviewer was unhappy with the sample size calculation you did (if I follow). You also wrote:
In the initial design, we planned to use One-way ANOVA for result testing, considering the outcome as continuous. However, since the questionnaire scores did not conform to a normal distribution, we eventually used the Kruskal-Wallis (K-W) test.
There are multiple issues here.
1) There is no point in estimating the needed sample size after data collection has ended. See Section 3 (retrospective power) of this short note by Russell Lenth: https://homepage.stat.uiowa.edu/~rlenth/Power/2badHabits.pdf
2) Your comment about switching from the ANOVA you intended to use to the Kruskal-Wallis test makes me suspicious that you relied on a statistical test of normality. Generally speaking, that is a very bad practice--especially if you carry out the test on the DV rather than on the residuals. But even if you carry it out on the residuals, tests of normality have far too little power when n is low, and have too much power as n increases. IMO, you would be much better off asking yourself if it is honest, fair, sensible, and defensible to use means and SDs for description of the DV (by groups). If the answer is yes, then ANOVA will likely be just fine. This issue has been discussed many times on RG. And I summarized my thoughts on it in a short conference presentation several years ago. You can view the slides here:
I doubt you can share your raw data, but can you at least share the n, mean and SD for each of your groups? Some kind of distribution plot (by group) would be helpful too--e.g., box-plots. Thanks for considering.
I hope this helps.

Here are some tips on how to deal with academic snobs:
  • Don't take it personally. It's important to remember that academic snobs are often insecure about their own intelligence and accomplishments. They may try to put others down in order to make themselves feel better. Try not to take their comments personally and don't let them get to you.
  • Stay confident. Remember that you are just as smart and capable as anyone else. Don't let academic snobs make you doubt yourself or your abilities. Remind yourself of your own accomplishments and strengths.
  • Don't engage with them. The best way to deal with an academic snob is to ignore them. If they try to engage you in a conversation, simply walk away or politely excuse yourself. There is no need to waste your time and energy on someone who is trying to make you feel bad.
  • Seek support from others. If you are being harassed or bullied by an academic snob, talk to a trusted friend, family member, or professor. They can offer you support and advice on how to deal with the situation. You can also report the behavior to your department chair or other appropriate authority figure.
Here are some additional tips:
  • Kill them with kindness. Be polite and respectful to academic snobs, even if they are not to you. This will show them that you are not bothered by their behavior and that you are the bigger person.
  • Have a sense of humor. If an academic snob makes a snide comment, try to laugh it off. Don't let them get to you.
  • Don't try to compete with them. Academic snobs are often competitive and driven to succeed. Don't try to compete with them on their own terms. Focus on your own goals and don't worry about what they are doing.
  • Be yourself. Don't try to change who you are to fit in with academic snobs. Be proud of your unique qualities and don't let anyone make you feel inferior.
Remember, academic snobs are not worth your time or energy. Focus on your own work and your own goals, and don't let them get to you.

Economics is not a science, but a profession. The professional focus is on private wealth management, based on various accounting techniques. In this sense, there are different schools of economic thought, with respect to the sources of wealth creation and distributive practices.

CoDesign Lab & Media Studies. Translation as interlinguistic mediation and creation of human interactions. Annie Gentes, in Journal of Human Mediated Interactions, Vol.10, n°1, Sylvie Leleu-Merviel, Khaldoun Zreik (ed.), 2010. a. Abstract: In human interactions, translation stands apart both as a specific work on language but also as a reflexive situation of communication. Traductology studies not only languages and interlinguistic uses, but also questions the translating process as a mediation. In this article we want to analyze what translation does to the speakers, the nature and legitimacy of their interaction, the materiality of their exchanges.

DISCOURSE HUMOR
Tough language (Aristotle's Ethos) is the language of the novel. It tends to be written in a first-person (I, me, mine, we, us, our) narrative; it is subjective and informal or intimate, and Aristotle would call it (Aristotle’s Ethos). It is the language of the novel. Frederic Henry in Ernest Hemingway’s Farewell to Arms uses tough language.
Sweet language (Aristotle’s Pathos) tends to be written in the second person (you, your); it tends to be subjective and intimate, and sometimes “pathetic.” It is the language of seduction; it is also the language of the advertisement. Aristotle would call it “Pathos.” Walker Gibson calls Sweet language AROMA (Advertising Rhetoric of Madison Avenue). Sweet language is listener-oriented in an attempt to deduce listeners into buying products they don’t want or need. Stuffy language (Aristotle’s Logos) is the language of academe.
Where tough language is I-oriented, and Sweet language is you-oriented, stuffy language is it-oriented. Stuffy language is highly grammatical and highly formal. Infinitives, gerunds, present and past participles, nominative absolutes, perfect, progressive, and passive constructions normally occur only in stuffy language. Because it is so objective and straight forward, it tends to be dull—stuffy.
Comment on the three styles of discourse: Tough (the novel), Sweet (the advertisement), and Stuffy (the language of academe).
