In this code, there is no direct definition of the threshold voltage (Vt). Therefore, it is not possible to determine why the threshold voltage is negative or positive based on this code alone.

In general, the threshold voltage of a MOSFET can be positive or negative, depending on the type of MOSFET (n-channel or p-channel) and the doping concentrations in the device. For an n-channel MOSFET, the threshold voltage is typically negative, while for a p-channel MOSFET, it is typically positive. The polarity of the threshold voltage can also depend on the doping concentrations in the device.

To determine the polarity of the threshold voltage in a specific MOSFET device, you would need to analyze the doping concentrations and the type of MOSFET being used.

Hi Bacha,

I'm not sure what physics you are using. Comsol needs careful implementation if you have moving/deforming domains. It is possible that you are not simulating/post-processing your results correctly.

Nowadays, smart electronic devices have become ubiquitous. These devices require power for their functioning. The conventional energy resources are limited in nature, and their consumption produces unwanted byproducts, which cause the greenhouse effect. (1,2) Therefore, there is a need for alternative energy sources that are clean, green, and renewable in nature. The existing renewable energy resources can generate a huge amount of energy, but they are intermittent in nature. Efficient storage of energy to meet the energy demand as and when needed is still a challenge. (3,4)

There are basically two mechanisms of energy storage: one is through batteries, while the other is using electrochemical capacitors/supercapacitors (SCs). (5,6) Both batteries and supercapacitors have fundamental differences due to their materials, structures, and charge-storage mechanisms. Batteries yield a high energy density because of their storing charges in a bulk of electrodes, while SCs may provide high power density via surface charge-storage mechanisms. (1,5−7) SCs have many applications in the field of uninterrupted power supplies (UPS), automobiles, and power backup to protect, enhance, and/or replace batteries. (1,2,7−9) SCs can broadly be classified into two categories on the basis of the charge-storage mechanism: (i) electrical double-layer capacitors (EDLCs) and (ii) pseudocapacitors. (2) In EDLCs, the electrical charge is stored at the electrode–electrolyte interface, while in pseudocapacitors, the charge is stored through redox reactions occurring at the surface of an appropriate electrode. (1) Charge storage via the pseudocapacitance mechanism exhibits some interesting properties as compared to the EDLC mechanism. (1,2,10) For this reason, a lot of work has been done for the storage of charge via the pseudomechanism for the fabrication of high-performance supercapacitive electrodes. (2) Many researchers have suggested that the transition metal oxides can be a potential candidate for supercapacitive electrodes due to the high surface area of the material. (2,9−12) Graphene has also been exploited for supercapacitor applications. (5,13,14) Currently, materials such as NiO, TiO2, Co3O4, RuO2, Ni(OH)2, Sr(OH)2, MnO2, Co3O4, Bi2O, In2O3, and Fe3O4 are being investigated as supercapacitors keeping in view their cost-effectiveness, high capacity, and environment-friendly nature. (1,7,8,15)

Thin-film-based devices have attracted lots of attention, as thin films exhibit physical and chemical properties different from those of the same material in bulk. (16−22) In the case of thin-film and nanostructure devices, the surface to volume ratio is large compared to bulk material. (22,23) The surface morphology of thin films (nanostructure) influences the functional properties of SCs, which play a major role in energy storages. Therefore, a detailed knowledge of the surface morphology is important for the fabrication of devices having the desired properties. (24) Generally, surfaces can be studied using classical parameters (average roughness and interface width), which are highly dependent on the scale resolution of the measuring instruments. However, these traditional parameters are not able to give deeper, nanolevel insights such as the correlation, roughness exponent, height fluctuations, and complex structure of a surface. (24−30) Therefore, we require a technique that is scale invariant. This scale invariance can be achieved by employing fractal geometry. (9,24−30) Fractal objects show a self-affine nature, which can be seen by rescaling the surfaces along horizontal as well as vertical directions with different ratios. (24,25) Recently, Yadav et al. reported a close correlation between the fractal dimension and wettability of a surface. (30) Ţălu et al. have suggested a relationship between the electrical resistivity and fractal dimension. (31) Guisbiers et al. explored the relationship between residual stress and fractal dimension. (32) Wang et al. reported a relationship between the fatigue threshold value and fractal dimension. (33) Foadi et al. studied the roughness-dependent wettability of vapor-deposited metallic thin films. (34,35)

Surface morphology plays an essential role in governing the supercapacitive behavior of the material. An enhanced surface area increases the reactivity. Recently, a fractal study of a Cu-doped Sr(OH)2 thin film as a supercapacitive electrode reported that the supercapacitive value enhances with increase in fractal dimension. (9) This suggests that surface engineering can be an efficient tool to adjust the surface area of electrodes with fractal porosity/granularity for further improvements in the performance of devices. (1,36) It is interesting to note that the electrode–electrolyte interface with fractal geometry offers an improved electrode–electrolyte interface. (1,9,36,37) Fractal objects have a higher surface area as compared to the substrates. (9,38,39)

Many researchers have reported that the performance of a supercapacitor is enhanced with metal doping as well as the formation of nanocomposites. (9−11,36,40,41) Recently, our group reported a high specific capacity (∼413 C g–1), energy density (∼45.95 Wh kg–1), and power density (∼2.6 kW kg–1) in an Sr(OH)2-based supercapacitive electrode. The natural abundance, low cost, electrochemical performance, and environment-friendly nature of this material has made it an efficient candidate that has attracted the researchers to use it as a new electrode for supercapacitors. The supercapacitive properties can be further enhanced by suitable doping of metals such as Cu and Fe. (9,11)

In this work, fractal concepts have been applied to explore the irregularity and fragmentation of the samples. As a test case, we have taken Fe-doped Sr(OH)2 samples fabricated using the SILAR technique. A detailed experimental characterization of the surface morphology, structural analysis, and electrochemical characterization can be found elsewhere. (11) Here, we have focused on their theoretical investigations using fractal characterization. Our study suggests that the Fe doping affects the roughness exponent and fractal dimension. The fractal model will maximize the electrochemically active surface area and minimize the energy loss during the transport of ions inside the fractal networks.

Uniformity of drug refers to the consistency in the dose and physical characteristics of a drug product, such as tablets or capsules, within a batch and between batches. This is important because variations in dose and physical characteristics can affect the safety and efficacy of the drug, as well as its stability and shelf-life.

There are several factors that can cause the uniformity of a tablet or capsule to be out of the approved specification:

It is important to ensure the uniformity of drug products in order to maintain their safety and efficacy, and to ensure that the intended dose is consistently delivered. Any deviations from the approved specification should be thoroughly investigated and corrective actions taken to prevent future occurrences.

On the assumption that the content of all the vials is, truly, identical, i.e. no pipetting error, all fills assured by weight, then the are a few things to check:

1. distribution of the vials - are they edge or centre of the pack? Centre dry last so if all the problem vials are in the centre, then more time in primary drying is needed.

2. uniformity of the vials - moulded vials can have very variable bases, which can affect drying (heat transfer through the base from the shelf). If using a tubing type vial, should not be an issue. If moulded vials are the problem, again extending primary drying is needed.

3. if none of the above, then more time, and perhaps a higher temperature in secondary drying should solve the problem. That is, unless there has been some defect in primary drying like a vacuum excursion that caused meltback of the ice ...

Thank You Mohammad. I will read the paper.

1. Use a cryogenic grinding system. This system uses liquid nitrogen to freeze the polystyrene pellets, which makes them brittle and easier to grind into a fine powder.

2. Use a hammer mill. This type of mill uses high-speed rotating hammers to crush the pellets into a fine powder.

3. Use a jet mill. This type of mill uses high-pressure air to grind the pellets into a fine powder.

4. Use a ball mill. This type of mill uses grinding balls to crush the pellets into a fine powder.

5. Use a vibratory disc mill. This type of mill uses a vibrating disc to grind the pellets into a fine powder.

6. Use a pin mill. This type of mill uses a series of pins to grind the pellets into a fine powder.

You can use drop casting, spin coating

Okay, but please do you know any code for constant beamwidth of circular array? Thank you for your answer again

This cannot be simply answered without detailing the process, but maybe a very general answer is low pressure = fewer nucleation sites and, thus, more homogenous growth.

M. Muger, on page 12 of his book, Topology for the Working Mathematician (2022), writes:

"The biggest omission probably is the theory of uniform spaces. Since they

have very few uses outside topology proper, the author is not entirely

convinced that they belong to the core that 'everyone' should know.

Also, there are many good expositions of the subject to which we would have nothing to add Cf. [298, 89. 157, 153], etc."

According to this definite opinion, for intance, the enormous theory of

quasi-uniform spaces is nothing.

Please carefully investigate other factors as well such as nature of electrolytes, inoculation source. Also double check the potnetistate whether is it working properly. Hopefully you will able to get something. Reevised it carefully and carefully see each step.

I have never heard anyone referred to as "a bedridden". I would think that people who are no longer able to be independently mobile as "people with mobility issues." There is a movement here in the US to use "person first" language when describing challenges or disabilities.

Clothes that adapt to changing climatic conditions, such as temperature, are called smart clothes, Or covering the surface of the product with a gel material with specifications that change with the change of temperature

without proper dimensional inputs (billet dia, required dia, number of passes, required surface finish in microns, etc) ... it is not easy for anyone to answer your question ...

The answer is very simple. If the material has a high trhermal conductivity, its temperature will uniformize very rapidly, i.e. all regions of the material are at te same temperature and have the same coefficient of dilation. If the thermal conductivity is low and there is a heat source at one end, the temperature there will be higher than at the other end of the material. The coefficient of dilation differs from region to region. If two adjacent regions dilate in a different way, the material may break (fracture) at the interface.

James E Hanson Hi Professor, I have tried using permanent magnets the issue is with PM is that the field intensity is non uniform and it tends to pull the powders out of the matrix. I find that most people in literature for magnetorheological elastomers tend to use electromagnets but I am unsure how they are able to cure their polymer matrix as the uniform fields even in electromagnets is within a very small region and it doesn't seem like it could accommodate anything to apply heat for curing to occur. Furthermore they test these smart composites using DMA or rheometers again for which they would need to apply magnetic field over a considerable area to measure change in the young's modulus of the smart composite. I have read about a PEM-1022LS magnetic system in some of the literature but could not find any info on what this system is online any chance you have heard of this?

A laser heating device should allow you to focus the heating area and vary the power. A CO2 laser would be the typical apparatus, but most any laser with variable power output should work.

Could try calcofluor. Acts as a vital stain.if you wash it out after exposing one generation, maybe subsequent generations would not carry the stain.

In general, it is difficult to have a strong interaction between hysteresis and pore distribution. A sample can have one or many predominant pore sizes and, as a result, a few maxima in pore distribution.

Fast fashion is not meant in the question; as fast fashion does jeaprodise quality in order to cycle its business through garment recycling under the name of new fashion!!!

Hi Suresh and all.

Only under static conditions, capillary phenomena are fully understood. As soon as the meniscus (interface between immiscible fluids in a capillary) start moving, its curvature changes, viscous dissipation occours and the surface energy associated with the interfacial tension between fluids also changes. Depending on the flow direction and the prevailing pressure gradient in the porous medium, meniscus curvature can reverse. For a given capillary, two expressions for Darcy´s law would hold simultaneously in different sections. Presently the phenomena are poorly understood. Check “dynamic capillary effect”.

Dear Aminu Moriki Ladan it depends of the number of parents involved in mating and their genotype. If either female and male parents are clones, F1 should be genetically uniform, at least external factors occur (mutations, contamination,...). However, if parents aren't clones, variations must be expected.

Now I've got it.

Here is my note and I think it can help this question.

One thing that we're also concerned with in using Good buffers is the formation of hydroxl radicals and their impact on redox chemistry. For our alkaline system, what appears to be a good option is the CHES buffer (pKa 9.5).

GoldBio has a useful selection guide as well: https://www.goldbio.com/documents/3565/Ultimate%20Buffer%20Selection%20guide-%20Arranged%20By%20FamilyCMPSD.pdf

It mean if math. formula is complicated, try some thing else, outcomes of tryout is a data, the standard deviation of data has the same meaning of RMS. GOOD LUCK

To the best of my knoeledge, the problem remains open in the more concrete setting of linear operators between Banach spaces, endowed with the usual operator norm. It may sound strange, but even the finite-dimensional case remains open! I have personally studied the problem, along with some co-authors, exclusively in the Banach space context, and mostly in the finite-dimensional case. I think that it is a particularly hard problem, even in this far more restricted scenario.

Without a shadow of doubt, the problem deserves far more attention from the functional analysis community, and therefore, I must thank you for focussing on such a simple yet deep question.

Having said all these, I do know of some interesting results by Lindenstrauss and Perles, Lima, Sharir, T. S. S. R. K. Rao among others on this topic. It might be fruitful to look into their ideas and results (again, mostly in the Banach space context). We have also tried to contribute something to this intriguing topic. We (Paul, Mal, Sain) we have obtained a complete geometric characterization of extreme contractions between two-dimensional strictly convex and smooth Banach spaces. We (Paul, Ray, Roy, Bagchi, Sain) have also been able to obtain some interesting conclusions on extreme contractions between polyhedral Banach spaces. Recently, with Paul and Sohel, we have also obtained a complete characterization of extreme contractions between finite-dimensional polyhedral Banach spaces. Most of these papers are available on RG and please feel free to look at them, should you choose to!

Of course, much remains to be done on this fascinating question, and from multiple points of view, including analytic, grometric and combinatorial. In short, a potential exciting journey into the unknown!

I recommend trying to follow methods from existing literature as closely possible. Works that have been highly cited likely have repeatable methods. Without knowing exactly what parameters you are experimenting with, it's hard to say exactly what the issue is. Certainly the concentrations, pH, temperature, and substrates all play a role. Please see these two papers, and I recommend some additional literature review to find more.

Hello sir,

Could you please tell me what method did you use for the formulation?

Do Check out if the method needs improvement.

Other than that, You can check out the possible reason causing Precipitation.

It can be either due to the

1) formation of insoluble complexes

or

2) two oppositely charged particles leading to electrostatic attraction clubs together

or

3) complexes interact with one another and form a neutral aggregation

or

and consequently results in precipitate

Please take a look at these articles, It may be useful!

In fact It is very frequent to think that equality means identity. But equality us about rights, not about being different in our identities. Being a man or being a woman means different identities with equal rights. So It is not a problem at all to wear different uniforms, if the curricula and the treatment are equal for both, girls and boys.

Omar Tarek ,

I would first sit down and describe at a high level the features that are desired for each of the modules. Be sure to account for feature dependency between modules. After doing so, the stage for particular algorithm that targets the different features can be derived. You can contact me here or privately to continue the discussion.

Clothing or creation of body covering probably correlates with the loss of body hair and the necessity of keeping warm. At the same time, perhaps, the use of fire began as a source of warmth. So the use of clothing and fire together perhaps sets humans apart.

To uniform the inoculation, you have to apply the same number of spores. You can culture the actinobacteria in solid media and after spore formation drags the spores with a spreader with some water. After making a spore-water suspension, you can count the numbers by using neubauer chamber under a microscope. The spore count method is easily available on the internet.

First, identify your dependent (DV) and independent variables (IDV).

After that, check the type of your variables- categorical( nominal and ordinal) or Continuous ( ratio or interval).

Now, check whether DV and IDV are parametric (metric) or not. [Otherwise, they are non-metric (non-parametric)]

if variables are non-metric (both DV/IDV) then apply crosstabs (chi-square).

if DV= metric and IDV= non-metric, use hypothesis testing.

if DV= metric, IDV=metric; use Correlation and regression.

if DV= non-metric, IDV= metric, use discriminant analysis or binary regression.

N.B.: Above mentioned techniques are for Bi-variate analysis.

Apart from that, you can use mean, median, mode counts, and percentages. (For univariate analysis).

Dear Shikha Marwaha ,

I do not know if there is a delta function distribution delta(E-Eti),

where Eti can take the values you intend. You can also assign them the concentration you need.

If there is no such function you can choose the Gaussian distribution function

Nti exp (E-Eti)^2/sigma^2

with sigma very small to mimic approximately the single level traps.

The content uniformity is in fact an assay method with additional dose testing, thus content uniformity. There is an accuracy number for n>=6 and the associated relative standard deviation that need to meet the acceptance criteria.

Hello Ankit Naik

I used to do the scratch with a 20μl tip and it is always going well. Here are some tips that may help:

if you do the assay using 6 or 24 well plates, you may use the plate cover as a ruler during scratching.

don't twist the tip and try to fix the angle between the tip and the plate during scratching. it is better to run the tip over the cells once. regarding the second part of your question, ZEN Blue Software is doing well and you can set it up with your inverted microscope camera https://www.zeiss.com/microscopy/int/products/microscope-software/zen-lite.html

you can also use any photoshop program, in this case, the width will be in pixels.

these may help you to optimise your assay

In most cases high entropy alloys are prepared by melting the constituents together at high temperature. Since the entropy goes into the Gibbs free energy always as -TS, the role of entropy is higher at high temperatures. Many systems (but not all) therefore can be single phase liquid. The fast diffusion at high temperature and in liquid state distributes the atoms homogeneously in a short time. If the high entropy alloy is single phase at room temperature, too, the cooling can be made at medium rate. Attention is needed to prevent segregation of elements during solidification. Some tempering at temperatures just below the solidus temperature may be necessary to homogenise the alloy by solid state diffusion. If the solid state is not single phase a rapid solidification can produce single phase homogeneous alloy.

Another approach is to use powder metallurgy and homogenise the alloy by diffusion of elements during sintering. Homogenbeous distribution can be reached also by atomising the liquid alloy and sintering the powder particles.

A powder approach is also the mechanical alloying of mixed powders. Here the solid state diffusion enhanced by high defect densities can produce homogeneous alloy. However mechanical alloying in most case is connected with impurity pick-up from the milling system or from the atmosphere (oxygen).
