I've submitted a manuscript to a journal early this year, and currently the status of the submission was 'Awaiting Final Decision', unchanged from May 2022. I've tried to reach the Editor in Charge (which also happens to be the Editor-in-Chief of the journal) several times from July via the journal's 'Contact Journal' option, but got no response. I've tried emailing the Editor-in-Chief and the publisher, still no response. I've emailed the Editorial/Manuscript Submission System, and they said they are unable to help since they are only responsible up to submission process.
I'm tempted to reach out to the other members of the Editorial Board of the journal (to reach out to the Editor-in-Chief about my issue), but I'm afraid it might be deemed unprofessional. Anybody have any idea what should I do or who should I contact?

For inexplicable reasons, the surface for the sample begins to spontaneously heat up over 100 degrees during the job.
After setting the temperature I need (for example, 25 or 37 degrees), the heating element continues to work and heats the surface up to 140 degrees. Forced stop of heating through manual setting does not help.

I am working with PEO and gel polymers for electrolytes and I have been able to make a homogeneous casting but the gel that I make has a habit of sticking to itself if it rolls at all. During punching and subsequent use is coin cells if the gel rolls and touches itself during assembly it behaves much like two sticky sides of duct tape, making it impossible to get back apart and wasting the material.
Any one know of any additives or other techniques to make it easier during assembly that I could try that might make it less sticky? The control gel I am using is PEO+LiTFSI salt in solvent and cast then allowed to dry to evaporate the solvent.
PEO (Mw 1,000,000) in case that has anything to do with it.

Answer
I went up to 18:1 and it seems to work fine. The higher you go the less sticky it will become. At the same time the conductivity decreases at higher ratios. It is exponential growth so the conductivity decreases fast.

The May 2022 issue of Canadian Healthcare Technology magazine has a feature report on the expansion of Electronic Health Record (EHR) systems to include genetic data. The article touches on a very important point in the first sentence, that a pan-[insert country here] EHR systems are mostly far off in many places, but in my view these would undoubtedly be beneficial to patients.
There is a regulatory and privacy landscape to navigate in different parts of the world, and a, sharing information between various states, provinces or regions, let alone hospitals within a single geography, is mostly a process covered in red tape and facilitated by the disappointingly familiar CNG tone of fax machines over a telephone line. Patient and clinician friendly processes and interfaces, along with built-in data standardization, a focus on computer-readable data capture, and interoperability are key to bringing genomic medicine into the digital age. The complexity and enormous potential of genetics and genomics in day-to-day clinical practice requires new approaches beyond pen/paper records and new technology beyond facsimile and traditional EHR systems to take us towards a better, healthier future. I would encourage you to read the article (linked below) and provide your thoughts on the subject.

Dear all,
I am running protein solution through various different types of glass columns (e.g. methyl silanised, soda lime or borosilicate glass) and I am struggling to clean these surfaces from any protein or buffer residues. So far I have used: buffer, di-water, acetone, IPA, acetonitrile and HCL solution (0.02M) but it seems that some proteins still stick to the surface. I am using water contact angle measurement to confirm the cleanliness of the columns afterwards and water spreads (slightly) more on the cleaned surfaces compared to a brand new surfaces (that has not been in touch with any protein solution). I wonder whether anyone has some tips on how to get rid of all proteins from the surface with don't destroying the glass surface (e.g. methyl functionalisation)

I would like to hear from fellow behavior analysts on massed trials and interspersed trials. Maybe I did not understand the concept well, so I will post here what I understand by each type of technique.
Massed trials: These are successive trials of the same task, usually presented in 3 blocks with 10 trials.
Interspersed trials: These are trials that are interspersed across multiple tasks, and multiple blocks are made between tasks to achieve 10 trials. That is, one of three trials of touch, then one or three of mand, then one or three of eye contact, and so on.
I usually use massed trials. From what I read in the last articles it is not clear which system gets the best results.

Dear all,
I am facing inconsistency between my DOS and band structures calculated from VASP. I have used the same algorithm IBRION = -1 and ISIF = 0, but ISMEAR = -5 for DOS and 0 for bands. From these settings, my DOS calculations show a Fermi energy of 4.4669, while bands are showing a value of 4.1753, the difference is pretty understandable, but behaviors are also different, like for DOS, CBM is touching the Fermi level, while in bands it is around 0.28 eV away from the Fermi level. If I subtract the DOS and band calculated fermi energy from my band structure data, then their behavior is matching, but what is the need of doing so? Can somebody please suggest that what can be the possible reasons for the same or where I am doing wrong?
Thanks in advance!
Relevant answer
Answer
Payal Wadhwa I think the Fermi energy in the band structure calculation is not accurate as you are not sampling the whole BZ. The Fermi energy calculated in DOS is usually more accurate as one normally uses a denser kmesh to do a DOS calculation sampling the full BZ. So, in my opinion, you should stick to the Fermi energy value calculated in DOS.
Hope it helps. Thanks!

2. Change gradient temperature range if your primers are specific.
3. Do primer titration if required .
4.Confirm your chemicals are fit for analysis before Trial. like try with another set of primers some other gene which already got results and just go for a pcr .
5. Use commercial master mix and try once rather with optimised reaction mixture.
8. Reduce the number of cycles to eliminate such non-Specific bands.hope this information might be useful to resolve your problem.
7.purify the product and again run the gel, whether it is having same non specific band send it for sequencing.

Answer
Dear Filipe,
many thanks for posting this very interesting technical question on RG. I think that Victor already provided a rather comprehensive answer. I fully agree with him in that the SR141716 (rimonabant) should be first completely dissolved in the desired amount of DMSO gefore adding aqueous buffers. If the resulting mixture becomes turbid, it might be helpful to try sonification in an ultrasound bath for a few minutes.
The preparation of stock solutions of Rimonabant is described e.g. in the following potentially useful article:

In Touchdown PCR, the annealing temperature in the early cycles is usually 3 5 C above the
standard Tm of the primers used, while in the later cycles it is a similar
amount below the Tm but why??
Relevant answer
Answer
In TD pcr the idea is to enrich the template with highly specific amplimer in a pcr that usually produces many nnon specific bands. The high early annealing allows very specific single strand amplification off the higher annealing primer. Then later when the second primer can anneal at the lower annealing temperature the correct product has increased in concentration so competes out the non specific amplifications because the right product now has a head start so the optimum annealing temperature is no longer quite so important

Hello everyone,
I've done a few ELISA tests and I'm wondering about how to mix correctly my samples (cell culture supernatant) and the dilution buffer during an ELISA experiment.
For some experiments, I've directly mixed the samples and the dilution buffer in the wells of the ELISA plate, but carefuly, without touching the well walls and the bottom. I had good results at the end.
But my question is simple, is it ok to do that?
I know that it's better to do the mix before but with a lot of samples, It's easier to directly mix in the wells. About that, do you have any advices or tips on how to do the mix of samples and buffer, for exemple in plates, tubes?..
Thank you in advance
Relevant answer
Answer
If you want to mix the sample and dilution buffer in the 96-well ELISA plate, you can avoid the risk of scraping the treated surface with pipet tips during mixing by using a plate mixer. The Eppendorf MixMate is a good one that has digital speed and time adjustments.
You could also premix the samples and dilution buffer in a 96-well polypropylene plate, then transfer the mixed samples to the ELISA plate using a multichannel pipettor.

The other property that can be sued is the metals are highly light reflective while the semicondcutor is partially reflective.

Relevant answer
Answer
Jordan, your question actually only may be addressed by a stability test (spiked samples, freeze them and then store them at different temperatures for some time). Depending on the results of your analysis and the importance of the conclusions you are drawing from them, it might make sense to set up such a test in order to corroborate your results.
On the other hand, if the samples are sterile, I'd be quite confident that no adverse effects have been happening. Are the steroids sensitive to oxygen or modification by enzymes which are released by broken blood cells? Are you observing hemolysis?
If you know the positions of your samples in the fridge, esp. if you are able to identify those which have been thawed, you could plot the results against the sample position/thawing status to check if the thawed samples are producing weird data.

Relevant answer
Answer
Dear Hirenkumar Ramanbhai Patel,
Auto scaling is a feature offered by many cloud providers like AWS and Google Cloud Platform which handles the creation and deletion of new servers in your network automatically, allowing you to scale your application to meet varying loads.
This is a CPU usage related preference scaling which automatically puts preference to increases or decreases in load. Auto scaling makes sure instances scale up or down depending on the load. Whenever your network reaches a predetermined amount of load, say, 70% CPU usage, auto scaling will fire up a new instance to smooth things out. When it calms down, it’ll scale down the number or instances. Auto Scaling allows you to scale up to meet any amount of demand; it can also save you money by scaling down when it’s not needed. This saves waste of money usually, because during off-hours when your application isn’t under peak load, you’re paying more than you need to. Setting up auto scaling cloud won’t be easy, but GCP has tools to make this simpler, such as being able to use a container as a machine image.
Please refer this article and understand well how they use it:

I am simulating a photodiode with the following structure from top to bottom;
ITO - top electrode
a-Si:H (Amorphous silicon) - gain medium
ITO - conductive layer
n-doped Silicon- bottom substrate
(electrode placed on bottom)
I first used Athena to create the structure, and when I read the file into Atlas, it makes the middle ITO layer an electrode. The middle ITO layer should not be an electrode. I also tried using a floating contact on the middle ITO electrode to try to "eliminate" it. Almost no current leaves through the electrode, but the voltage in this layer is no longer continuous with the other layers touching the middle ITO, so I am not sure if this is a valid way to simulate it.
When I use Atlas to create the structure, I have more control to define the electrodes, but I get convergence issues when I have ITO as the middle layer. When this material is changed to SiO2, I am able to run the simulation.
I have posted the floating contact method to this file.

Obviously, you need to add the properties of the plastic you’re dealing with to the software‘s library. The thing is the properties of PHAs are not available on such softwares. So you have to do some rheological, PVT, and thermal testings to get such properties which will be costly if you don’t have the equipment.
** Please take a look at the attached required properties (for another type of plastics) to add materials to any injection molding simulation software, can you suggest any way that can give me a rough approximation for such properties without carrying out the tests; because I don’t have the equipment.
- Materials suppliers don’t have these required properties too.
Any replies will be highly appreciated.

Hello everyone,
I have some PHAs blended with fillers and nucleating agents, yet I don't know what kind of fillers or nucleating agents. The producer has shut down and there's no way to get in touch with.
** Any ideas how can I identify the type of fillers and nucleating agents?
I was thinking to use EDS to identify the type of fillers, I am not sure though...

The question resembles a sophism because it contains a contradiction in itself, since NOT CHOOSING IS ALREADY THE RESULT OF A CHOICE WHOSE RESULT HAS BEEN, PRECISELY NOT CHOOSING; It is a subject very much treated by Existentialists and Cognitive Psychology: We are always choosing and, "not doing it" is a mere illusion since it is the fruit of a decision: not to choose ... precisely that continuum be subject to choice and decision-making processes, so that when opting or choosing an option (even if it is to "not choose") other possible options or possibilities of choice are "killed" and, this, produces anguish and confronts us with the existential nausea or the purest nihilism.

After reported first coronavirus case in State of Washington January 20, 2020, and seeing first case death in Seattle Hospital, quarter there had been more than 10,000 case reported in Seattle hospital itself. The life of normal human being has been changed so far. It has started with buying basic shopping in grocery stores to entertainment and shopping.
The question is here that what New Normal is for consumer who was regularly visited shopping malls, cinema halls, musical parks, resorts and other public events.
Will consumer behave the normal way as they were doing previously?
The effect of Covid-19 will remain forever or it will vanish with the time…???
Let me brief my experience of shopping in a store in North Carolina (USA) after the store just opened from the lockdown. We went for Guitar shopping and in the process, I visited two stores in-person and before that I visited many websites to understand the basic features and other essential accessories for the guitar for beginner. We were about to book online seeing online deal of the product but we hold our decision for a day. After brainstorming, we decided to visit some stores at least to have a look of guitar and just to have feel of it while holding guitar in hands. Please note here that I mentioned here to have feel of Guitar. That’s very important for consumer in buying at least in some product/s to have feel while consuming it or using it.
Since we are first time guitar buyer, it is very important for us to have a feel before buying it. In case of guitar, I understand during the buying process of guitar that guitars are available in different sizes, shapes and strings. The material is also very important and keep in mind while buying as a beginner buyer of guitar.
So again come to the point of buying product after New Normal…. Is not a Normal anymore, isn’t it?
When we entered into a store of Guitar, we were told to sanitize our hands and not to touch anything unless you finalize your buying decision. Of course, they allow to touch on your two or three options but not randomly touching all that you want to see like previously you did in a store normally. Now that is not at all Normal. Because storekeeper has to sanitize all the products what customers have touched to see? Uff! Isn’t it big task? More important he cannot cater or allow all the customers depends on the size of the store to enter at a time. Storeowners has to have a dedicated person to supervise this in a store.
So now there is one more role added in the storeowner duty i.e. apart from cleaning or better to say sanitize all the products before opening the store, during store hours and while closing the store, make sure all the staffs wear masks and hand glows and keep customers in line in tact in store so they can follow “six feet distancing” among all other next customers.
This is just one small example for buying guitar in a store. There are number of products irrespective of its nature of origin.
Tipping point:
The challenge is that how the business offers products to the consumers in New Normal.
Will consumers back for shopping as usual or they restrict themselves not to be in public immediate contact of any such products?
What experience can business house offer to consumers in New Normal?
What about the products that we try buy wearing and having ‘touch feel’ of it before buying?

I do not know could I use the "No touch" calibration ? then Do I need to move the probe to the sapphire to determine the deflection sensitivity and Sync distance by Advance calibration ? I confuse when we should use "No touch", "Touch" and "Advanced" calibration ?
Thank you in advance your answer.
Relevant answer
Answer
Depending on what you wanted to do with the colloidal probe, you will need to calibrate the normal and and lateral spring constant where the latter is needed to calculate friction coefficient. I used thermal tune method to calibrate the normal spring constant and Sader's method ( Rev. Sci. Instrum. 75, 1988–1996 (2004)) to calibrate the lateral spring constant.
You can perform thermal tune method directly from the Nanoscope software by ramping the AFM probe against atomically flat surface i.e. silicon wafer.

Hi all, I wish to understand why doesn't all polymerase can detect a single copy of region of interest?
While some polymerase is more sensitive (like dreamtaq), and some are less sensitive, what is the difference if the primer annealing condition is the same? Is it due to affinity? What caused the variation, what is that factor?
How about increasing PCR cycle to detect a single copy? If unspecificity is an issue, then how about utilising touch down PCR first?
-------------------------Answer Update (9/6/2020) -------------------------
To summarise the answers from below, assuming all DNA and water is clean with no contamination in reaction, the lower plasmid number detection limit is different in different companies (like DreamTaq v.s. Q5) due to following reason.
1. The salt composition in different buffer (affecting annealing), possible that manufacturer weight between specificity and sensitivity. We can also see different enzyme recommends using different Tm. Tm-5 to Tm+3.
2. Innate performance of polymerase and response to other additives (accounting to % of actually active taq in solution)
3. The statistical chance to amplify one single plasmid in respond to 1 and 2.
Relevant answer
Answer
I think that the quality of the pcr primers is more important than the polymerase. Most polymerases are still active at more than 35 cycles which could theoretically generate 35 billion copies but in reality if the primers anneal even slightly in the wrong place the false bands will amplify well and spoil the results. For this reason nested pcr is often used to increase the specificity of the band while maintaining strong amplification. A top quality enzyme with poorly designed primers will still give a bad/wrong result. Touchdown pcr often works well but if the higher annealing primer can anneal in more than one place then it will not help. This can happen with gene families, pseudogenes or even common motifs in the genome.

I have been trying to simulate an MMC in a rectifier-mode using PWM.
First, I modeled a single phase MMC on PSIM software and simulated it in an inverter-mode, and made sure it worked. Then I connected a voltage source on the AC side and loaded the converter on the DC side (effectively making it operate as a rectifier), using the same PWM scheme. I get a zero voltage at the DC side as the AC source seems to be shorted through both the upper and lower arms, hence there is no voltage between the positive and the negative output DC terminals. Is there any difference in terms of modulation, structure, or any other, between an MMC rectifier and an MMC inverter? Most research papers seem to talk about an MMC inverter, never touching on the MMC rectifier.
Thanks in advance for your contribution.

I plan to use Image J for analyzing images, specifically for computing the stained areas on the images. I feel it is an inefficient and time-consuming exercise to analyze images using ImageJ on computers; has anybody come across an alternative, specifically on touch screens systems i.e.iPad or Surface which are equally accurate?
Relevant answer
Answer
I agree with Bruno in that the use of scripting/automating saves a lot of time. For example, I process a lot of histology images, and I separate stains using the color deconvolution tool (https://imagej.net/Colour_Deconvolution) and then threshold. And using the macro recorder makes automation easy, and I can batch process images.
However, I have found that scripting doesn't work so well in situations where the software cannot distinguish between structures. For example, having it measure the perimeter of a specific organ/structure in a section through the whole body is difficult. The human eye can differentiate the organ, but as it has similar staining properties to the tissues around it and is slightly different in shape in different sections, the computer makes bad decisions. To date, I haven't come across a good piece of script that can handle these situations (if you know of one, I would love to try it out!). Often you must hand trace around the structure of interest, which is indeed inefficient and time-consuming. Tracing with a mouse is a real pain, but a stylus on a tablet is much faster and easier. Once it is saved as an ROI though, the script can come in.
