I am looking at identified candidate genes for isolated orofacial clefts identified in various populations to see if the associations are replicated in a UK population. (Along with environmental exposures).
I will be using a secondary data source only, and I am aware of papers that explain what analysis is needed for primary data but I haven't seen if this differs for the use of secondary data?
Relevant answer
Answer
Georgia Awcock Case-control Secondary data genetic association studies often employ a variety of statistical approaches to examine the data and assess the strength of the relationship between genetic variations and the illness of interest. Among the most frequent approaches are:
1. Logistic regression: This approach is used to calculate the odds ratio (OR) and 95% confidence interval (CI) for a genetic variant's connection with illness. This may be used to analyze both the main impact of the genetic variation and the interactions between the genetic variant and environmental exposures.
2. The Cochran-Mantel-Haenszel (CMH) test is a statistical test used to examine the relationship between a genetic variation and illness while controlling for other factors such as population stratification.
3. Haplotype analysis: This approach is used to examine the inheritance patterns of numerous genetic variations in linkage disequilibrium. It can be used to identify particular haplotypes linked to the condition.
4. Multivariate analysis can be used to investigate the combined influence of several genetic variations and environmental exposures on the illness of interest.
It should be noted that when utilizing secondary data, it is critical to ensure that the data is of high quality and that the genetic variations and environmental exposures were quantified in the same way as in the main study. Furthermore, before beginning the study, it is critical to have a well-defined research topic, a sample size calculation, and a pre-specified plan of analysis.

When publishing a book, what are the things I need to take of or be aware of?
Thank you
Relevant answer
Answer
We will assume that the publisher is found.
Later, the author must become a perfectionist, based on the fact that any typo in the text will be carefully reproduced, despite the presence of proofreaders and editors. It should be understood that only for the author the text is a "masterpiece", makes sense, etc., while for the editorial staff it is just routine work that must be handed in on time and they are not experts on this topic (but, like everyone else, "have something to say").
I dealt with the publication of books and saw several simply egregious cases: for example, in one of the books "marginal notes" were carefully reproduced (the reviewer got carried away and began to think, but thinking is generally harmful (c) - V.G.). In another case, the editor made changes to the text that made it very stupid (but "correct" in the editor's opinion). And I'm not talking about the fact that typos corrected once mysteriously appear again and again. Once, instead of the edited and verified text, the original text was reproduced in the publication - they "did not find the last version ...". Therefore, it is necessary to know the manager who is directly responsible for your text, to have good contact with him and clearly, in time fulfill all the editorial requests. When proofreading texts, do not be lazy and read everything again, and send the necessary corrections in the form that is accepted in the editorial office, but is not convenient for you.
Anyway there will still be typos... Recently I was proofreading my wife's book - the fourth edition is being prepared and found a few misprints again...

Background:
In control theory we often develop new methods for analysis or controller/observer/filter design and usually evaluate them with numerical simulations. In many papers only a few selected examples are considered.
I think it would be desirable, if there was a catalogue of potential example systems which contains a variety of system models from one could select those which are suitable for a specific use case. A colleague and I are working on such a catalogue (see https://ackrep.org for more information).
After establishing the framework, a basic ontology ("Ontology of Control Systems Engineering") and some preliminary examples (e.g. cart pole system, Brockett integrator, some PDEs and DAEs), we now look for more content. Another colleague recommended http://www.compleib.de/ which contains > 100 linear state space systems.
I am also aware of some other small collections of nonlinear/mechanical systems (available only as PDF file) such as :

There is no such service available at the moment. Generally, journal reviewers will not make the same comments. Nevertheless, you can obtain a opinion from your supervisor, known experts and colleagues before submission. Their opinion and comments will not guarantee that your manuscript will be accepted in a journal in first attempt. My suggestion is that you upload your draft to a relevant journal in your field of research. Learn from the cycle of submission, rejection and submission in course of time to fine tune it.

The average multiple difference between the qubit dsDNA (miniprepped bacterial plasmids) and the Nanodrop is ~ 1.8x
Does this mean my plasmids are particularly contaminated or of poor quality?
Is it normal for there to be such a drastic difference?

I am aware that PC's are 2-D groups of clustered data which explain variance in a dataset, but am unsure how I can refer to PC1 and PC2 when reporting on differences in the produced trends. Since PC1 and PC2 explain the most variability in a set, I wanted to refer to these as the "dominant" and "subdominant" trends for my produced graphs, but am unsure if classifying PC1 and PC2 by the terms above is incorrect.
Any clarification on the differences between PC1 and PC2 and whether I can technically refer to these as "dominant" and "subdominant" trends would be appreciated.
Relevant answer
Answer
Hello Liam,
The extraction of components is such that the first PC will always be that linear combination of variables which accounts for the largest possible portion of total variance in the data set. As subsequent components must be linearly independent of previously extracted components, PC2 will always account for a lower proportion of total variance than the first extracted component, and so on. The k-th PC extracted (for a set of k variables) will account for the least amount of total variation.
Sometimes, you will encounter studies in which the researcher has chosen to rotate the chosen solution in multi-dimensional space (when the chosen solution has more than one component). This can and will redistribute the amount of variance associated with a given component, when compared to the amount associated with that component upon extraction. The total variance accounted for by a set (or subset) of components does not change due to rotation, just the allocation by individual components.
Rotated or not, whether the resultant components make conceptual sense is in no way guaranteed for your specific sift of variables (and their specific method of quantification), given your specific sample. So, labels such as "dominant" may or may not be meaningful; as well, they can change if one rotates a given structure.
Good luck with your work.

I am looking at example 1, Chapter V, Sec. 19 of the Dover edition of Wasow’s “Asymptotic Expansions for Ordinary Differential Equations”. This is the latest edition of which I am aware. Although this example is an excellent one for demonstrating shearing transformations and determining an appropriate change of variables, the alleged fundamental system to eqn. (19.30) is clearly erroneous. The following formula is likewise in error although consistent. Is this overlooked in all reviews and revisions? After all, a fundamental series is, by definition, an exact solution and not just a formal series. One may expect addition of lower-order terms in (19.30), but the author explicitly rules this out and claims to have achieved a terminating series.

Recently, a fashion developed to post preprints on RG or other web media.
As a reminder preprints are manuscripts, thus submitted research that did not underwent the reviewing process.
This is a way of sharing research faster would say some. Indeed, we are unfortunately living in an accelerating world, and science does not stay alongside the road.
However, I see here some reasons to doubt about the possible benefits of posting preprints:
· The benevolent work of the associated Editors and Reviewers is somewhat non-respected, denigrated. It is already sometimes difficult to find some reviewers, and such lack of consideration may lead to really loose the interest for reviewing.
· Ideas or findings in preprints are spread away from their initial scientific domains. For geology (my domain), this may not be a critical problem. But for the medical domain, and overall nowadays, spreading non-quality checked ideas/concepts/results may have some consequences. If the manuscript is rejected, then only the authors are really aware. But the diffusion of the ideas/concepts/results that are rejected is done. This can lead to serious issues.
· There is a risk of plagiarism-related problems. As illustrated by a case raised in a question here on RG, ideas/concepts/results are shared with a community. The manuscript can be rejected or necessitate significant revisions, and then during this period, others may have time to re-bake the ideas/concepts/results of the initial preprint and publish them faster somewhere else. A game of “table tennis prosecution for plagiarism” may then start.
Meetings, conferences are the places to introduce some advances, some “half-baked” ideas (as would have said R. Bathurst), and they should continue to play this role. I think we should let the peer-review process to do its job, but I may be wrong.
Ideas, comments, all welcome!

One of my friends was accused of plagiarism; do you know why?
After about three months, his research paper was rejected because of plagiarism. When he checked the journal report, he found that his paper was accused of plagiarism with a 61% percentage. The reason is that his manuscript was previously uploaded as a preprint. It took him another two months to solve the problem and remove the manuscript from the database of the preprint.
So, in order to solve this type of issue, it may take several months of following up to remove the manuscript from the database of the preprint. Anyhow, If there were accusations of plagiarism, it is not well for any researcher's reputation, in any meaning.

I am working on an e-beam process that defines metal gates with extremely high sensitivity to the repeatability/resolution of the defined geometry. I am looking to improve our recipe since we currently use acetone at room temperature as our lift-off solvent. 
We currently use a PMMA bilayer for the resist stack. The first layer is PMMA 450k-A2 with a bake time/temp of 90 secs/180 C, and the second layer is PMMA 950k-A2 with the same bake time/temp. 
As I said, our current lift-off recipe is soak in acetone for 1 hour at room temperature. I often see black residue after lift-off under the SEM (coined "the black veil of death" in literature), and also have seen what looks like metal particulates in places they should not be. I am aware of many other solvents that can be used instead of acetone to potentially improve our yield. 
From talks with others, 3 different solvents have been recommended to me (I'm sure there are plenty of others), and I'm trying to decide which one to use for the best resolution/repeatability. 
1. Microposit PG-Remover (NMP-based)
2. Microposit 1165 (NMP-based)
3. Technistrip D350 (DMSO-based)
Is anybody familiar with the pros/cons of these different solvents for lift-off? Any other recommendations? Anything to watch out for (etching of metals/oxides that could occur over time)? I've read literature on DMSO vs. NMP, but practically are there big differences for lift-off?

Shall we have previous genetic variation in explant tissues used in in vitro approaches, how can we estimate an adequate ratio for somaclonal variation among regeneration events?
In tissue culture we use several plant tissues and “reprogram” the cell development to obtain somatic embryos, calluses, shoot meristems, whatever.
Considering that the raw material we start with would not have a chance to follow another developmental sketch (E. g. a spongy parenchyma cell) is expected to die as originally planned, a spongy parenchyma cell.
It is clear that some stress triggers, frequent cell divisions, growth regulators and other substances, may increase the mutation ratio differently. We may also consider that there is a tiny probability of this mutation events occur by chance.
My reasoning is, how can we correctly attribute a somaclonal variation ratio being aware of the possibility of mutations that would not jeopardize a cell developmental path already settled in an explant (a chlorenchyma cell for instance) that, was not for the tissue culture detour, would “kick the bucket” as such (a chlorenchyma cell)?

In many universities, notably in North America but most likely around the world, there are five-year reviews of professors throughout the careers. The reviews can take the form of assembling pretty well everything they have done in the previous five-year period, including providing vast documentary evidence of satisfactory (or even outstanding) performance in teaching, research and scholarship, and service (and, if applicable, in administration). This is generally an extremely time-consuming, intense and potentially stressful experience, and, equally, it is not always clear what the value of this exercise is. In addition to the potential for (conscious and unconscious) bias throughout the process as well as a number of forms and sometimes quantitative configurations, there is also the normative consideration of ensuring that full weight of given to the contributions that are presented for review. Although the broader public may not be aware of the working conditions within academia, it is important to note that, generally speaking, there are a number of regular evaluation-points that professors routinely must face, including: annual reviews, tenure and promotion reviews, grant proposals, conference presentations, articles and other publications, sabbaticals, teaching evaluations by students, some positions and committees, research chairs, etc.. My question seeks to understand—if there is already robust, intense, high-stakes, regular and relatively comprehensive evaluation of academic performance—is there (significant) added value to these five-year reviews? I am aware of some universities that have eliminated them, and others that have re-negotiated the requirements, but they do remain for the most part intact. Do they support and cultivate more enhanced engagement and performance? How? Would the time and resources required for this process be better spent in cultivating more enhanced engagement and performance?

The membrane used in reverse osmosis retains minerals like Ca, Fe, etc., and can affect bone density in healthy individuals. The final verdict is to use R.O water only in a case when the bone density isn't reducing otherwise mineral water is fine until the ppm exceeds.

Ants are important mediator for a number of plant species that (either rely on or not) their services as seed disperser. During a field trip, we have noticed a special phenomenon in which some ants picked up plant seeds only when they were positioned in the middle of the trail followed by the animals travelling on the forest floor; and seeds put outside the trial were generally ignored. This seed dispersal mode appears in contrast with active foraging by the workers. Are you aware of similar phenomena, what is the possible implication to plant regeneration and the different role of ants play please?

I am looking at the most robust software that is readily available to positively identify individuals from their unique coat marks. If it helps, I am looking for a software that can work best for cheetahs and I am exploring all possible options. Thank you in advance!
Relevant answer
Answer
Hi Lovemore
I believe wildID recently released an update which appears to be pretty effective with poor quality camera trap images.
As an alternative, Hotspotter seems to work quite well with leopards (and I'm sure it will work fine for cheetahs) and it is open-source. Having a bunch of reference images of each individual will probably help.
Here is a comparison between the two softwares, although this was before WildID's recent update.
Comparatively is appears as though Hotspotter performed better, with a higher % of correct matches and fewer false-positives compared to wildID. Image quality is a considerable factor in the success of the ID, so visual confirmation remains important.
Hope this helps

Willem

Looking for recommendations for sputter coaters. All the ones I've looked at seem to be, by and large, the same. Looking to sputter, C, Au and Au/Pd. Any important differences I should be aware of? Thanks!
Relevant answer
Answer
Dear Garrett, we've bought two different systems in the past - the main difference was the size and shape of the sputter target. One system had a ring-shaped target, which is difficult to exchange, so that you have to rely on the support of the supplier company, that you'll be able to get suited targets in, say the next 5 or 10 years. The other system simply has a circular-shaped target, where you can easily replace the target material to whatever you want. We have now used that system not only for standard coatings like the ones you've mentioned (such as Carbon, Au, Cu, Pd), but also for much more "exotic" materials like W, Ta, Ti, Al, ... and even a high-TC superconductor YBa2Cu3O7 and other compound materials. So I would strongly recommend a system with an easy exchange of targets and the possibility of using self-made targets. Best regards, Dirk

Hi,
I am working on a model predictive control of inverter using a Microlabbox or DSpace 1102. Recently, I found that working with Microlabbox beyond 2e-5 us is a tough task. I came to know that, for dSPACE1104, there are slave PWM blocks to working with low sampling rates. But unfortunately, there are no such options in Microlabbox. I am aware of the s-functions based model but looking for an alternative to that. I request you to guide me in working with more complex models such as sample-based controllers at low sampling rates. please share some useful information in this regard.
Thanks in advance.

These are the ways.
1. Get the supporting software for FPGA programming. Then you can operate a very low sampling rate.
2. Check for the turnaround time in a control desk. So that you can identify and fix the high computations.

EDIT: In case anyone else has this issue I have developed an R script to do this.
I need to transform approximately 1,800 rasters to roughly gaussian distributions using R. My plan was to use a Box-Cox transformation, as I can then iterate through all the rasters and more-or-less leave the script to its own devices (since Box-Cox finds the optimal transformation). However, I have not been able to find any packages that can run a Box-Cox on raster data.
Other than making a function myself, is anyone aware if there are any existing packages or scripts that can do this process? I am aware there are possibilities for this in GIS platforms, but would like to keep it in R if possible since the rest of my workflow is through R.
Many thanks in advanced
Relevant answer
Answer
Thank you Nikolaos for the request. Attached below is the function (as a txt file) for anyone interested. The function is pretty simple and involves getting the raster value table and then using that to calculate an appropriate lambda value for Box Cox transformation, and then running the transformation manually. People more experienced with R might be able to slim down some steps but as is it should work reasonably well.

Can you autoclave 100% glycerol straight up to sterilize it? Will it result in caramelization or will it be fine? I am aware I can dissolve it in water and autoclave it but it would make things easier for me if I could have 100% sterilized glycerol.
Relevant answer
Answer
Glycerol can perfectly withstand autoclaving. However, for practical purposes, I prefer to autoclave a 60 % (v/v) glycerol solution, prepared by weighing glycerol to avoid problems due to glycerol sticking to volumetric devices, because at 60% concentration, it is less viscous and much easier to pipet.

Hello fellow researchers,
I recently started learning how to use SolTrace and have been struggling with exporting the heat flux data from SolTrace. I am aware that we are able to see the flux density under the "flux maps" tab. However, under the "Data" tab I only see columns of data for pos x,y,z and cos x,y,z, element, stage, and ray (a total of 9 columns) and no Flux density data.
I believe I am missing something here, maybe there is some calculations I need to do for these data to find the heat flux but I am not sure how to move from there. I would appreciate it if I can get some guidance on how to export or calculate the heat flux values from SolTrace.

Answer
Thanks for your answer and sorry for this very late reply!
I should have been more precise in my former message. The sections, I am talking about, are generally located at the entrance of prehistoric cave/rock shelters. They are thus subject to climatic/biotic forcing (rain, wind, frost, biological development,...). They have not been backfilled as they are used as stratigraphic references.
The main solution we are able to suggest now is to protect them under a roof. Sections will be protected from rain; it will reduce the effects of wind, frost, and biological development. I am nevertheless wondering if another solution is possible.
Thanks in advance for any suggestions.

Hi Folks,
Have you investigated publications associated with COVID-19 host risk factors and immunopathogenesis related research?
We are all aware that SARS-CoV-2 infection and disease risk factors are complex, resulting in widely varying outcomes, ranging from asymptomatic to severe illness, and death. To be able to evaluate one's own risk related to COVID-19, multiple contributing factors must be considered, including the well known and frequently discussed risk factors of old age, obesity, diabetes, social circumstances, environmental circumstances, and other commonly described co-morbidities along with SARS-CoV-2 variant behaviors. However, the well known and openly discussed risk factors are insufficient to explain the widely varying outcomes of SARS-CoV-2 exposure. Therefore, in the commonly used public domain information sources, some information is missing concerning additional, lesser discussed, but potentially critically important risk factors. It is clear to me that there is no single factor that can determine any particular individual's risk, therefore more information is needed to aid in risk assessment. In no way is this information outcome deterministic, and only represents additional statistical factors to consider when assessing one's own risk to exposure to SARS-CoV-2.
Well, I recently started looking into some of this research, and I would like to share some research that I think could be very important, and ultimately shed some more light on COVID-19, human host immunopathogenesis, and risk. Some of these papers summarize and evaluate research, performed by others, on various host factors that may be additional indicators of SARS-CoV-2 infection and associated disease severity risk. I have included links to articles, preprints, and studies so that we all can be aware of established and up and coming research. All of these articles are open and freely available to the public. I have also included a link to the Wikipedia website on global blood type distribution as a general reference. Do you know your blood type?
I am providing this information to you in the role of a Pure Scientist as described by Rojer A Pielke Jr. in his book titled "The Honest Broker: Making Sense of Science in Policy and Politics." I let you interpret the information and decide on its importance and relevance.
Please feel free to comment on this research.

Hi, thank you for reading my question.
In some references, I have seen a phrase like "basic pKa" or "pKa for a base".
Example reference:
pKa is defined for acids. I was wondering what "basic pKa" means?
I am aware of the relationship between pKa & pKb:
pKa * pKb = pKw
Is "basic pKa" the same as pKb?
Relevant answer
Answer
The pKa value is one way for determining an acid's strength. The negative log of the acid dissociation constant, or Ka value, is pKa. A lower pKa value denotes a more potent acid. That example, a lower number implies that the acid dissociates more completely in water.
The pKa and pKb values are used to compare the acid and base strengths. For acid dissociations, pKa is specified. For base dissociation, pKb is specified. pKa and pKb vary in that pKa is the negative logarithm of Ka, whereas pKb is the negative logarithm of Kb.

I suggest doubt, and caution, about any such offers. At best, they might charge you a fee to "publish" on your behalf. They might just take the fee and disappear. If they do publish anything, it would likely be somewhere obscure that would not come to the attention of libraries, scholars in your field, or any other potential readers.
You could do an internet search for information about the sender of such mail, just in case it is a legitimate publishing house -- which I doubt. Sometimes, just typing the name into the search field, followed by the word "scam," will tell you all you need to know.
