I have a good experience with using Inkscape for creating SVGs out of the PNGs from Pymol. I usually use the Multicolor/color mode and 8-10 scans (colors) are usually sufficient, otherwise default settings can be kept. More help for Inkscape tracing bitmaps is here: https://inkscape.org/doc/tutorials/tracing/tutorial-tracing.html

@Davood-Omidian yes i understand your answer, it is very important, I will try it, thank you very much

There are several ways to convert a daily series into a monthly one. Popular methods include

What you do now depends on the nature of your monthly variable and the process you are trying to capture. Look at the economics or finance of the process. For example, if you think that your monthly variable is dependent on the volatility and level of your daily series, you might consider using one of 1 to 4 for the level and 7 or 8 for the volatility. There are many combinations that might be useful but that is up to you. It may also be necessary to log transform your variables before analysis.

There are several methods that can be used for solid embedding of fungal specimens to allow fluorescence in situ hybridization (FISH) and confocal imaging. Some of the most common methods include:

Each of these methods has its own advantages and disadvantages, and the best method for solid embedding of fungal specimens will depend on the specific requirements of the experiment and the characteristics of the specimens. It is important to carefully consider the specific needs of the experiment and the properties of the specimens when selecting a method for solid embedding.

Dear Andrea Ossicini ,

You are right to question the journal. The publisher behind “Journal of Research in Applied Mathematics” is Quest Journals Inc., a publisher mentioned in the Beall’s list (https://beallslist.net ). This is a red flag that this might be a dubious journal/publisher. There are more:

-Prominently mentioned impact factor https://www.questjournals.org/jram/impact.htmlis fake. The mentioned SJIF is a notorious misleading metric (https://beallslist.net/misleading-metrics/ ) often used by predatory journals

-One of their journals is not discussed positively here on RG https://www.researchgate.net/post/Journal_of_Research_in_Humanities_and_Social_Science_Is_a_real_magazine

-In the above link it is suggested that there is a link with IOSR (another dubious publisher mentioned in the Beall’s list). Indeed, the lay-out of the papers suggest a link

-Contact info Mayur Vihar, Phase 1, New Delhi, India is vague

-They make use of misleading info in their mails by referring to a real and legit journal with the title Quest (https://hrcak.srce.hr/file/387134 )

-Had a quick look at some of the papers in “Journal of Research in Applied Mathematics” and looking at for example the difference in editing (if any) I suspect numerous cases of plagiarised content. Take for example https://www.questjournals.org/jram/papers/v8-i5/A08050103.pdf (I suspect that the authors are taken for the internet and that they are not aware of this one)

Together with the fact that none of their journals has a serious indexing (Scopus, ESCI/SCIE etc.) I would say avoid this one.

Best regards.

Ijaz Uddin When a time series abruptly changes at a point in time, this is referred to as a structural break. This change might include a shift in the mean or a shift in the other parameters of the process that generates the series.

A structural break in economics can occur as a result of a war, a significant shift in government policy, or another similarly abrupt event.

Truman Prevatt thanks a lot, there is a lot of literature I need to read about.

The expansion of the Hadamard product of Xi(s) and its Taylor series of Xi(s) around 1/2 has let me obtain at least two valuable expressions that related the coefficients a_2n of that Taylor series with the real par of there non trivial zeros.

Abel Plans is fascinating because let’s evaluate any s in that expression letting find a value of Zeta(s), especially in cases where s is simple like s=0 . The formula contains the attractive 1/2 in one part of the definition when it is properly.. I want to revise all the details documents you have provided me. Thanks and I will be asking later about curious results.

Have a nice Sunday

How can that be done considering that unemployment is usually very high in developing counties and taxation is usually weak?

Rhianon Allen wrote: "...most parametric analyses assume normality."

Normality of what, though? There is much confusion about this!

Better textbooks clarify that for OLS models (including t-tests and ANOVA), it is the errors (i.e., deviation of actual values from fitted values using the true, population regression expression) that are assumed to be normally distributed. But sadly, not many books point out that normality of the errors is a sufficient condition, but not a necessary condition.

The necessary condition is that the sampling distributions of the parameter estimates (i.e., the constant & the regression coefficients) be approximately* normal. As was implied above, if the errors are normally distributed, the sampling distributions of the parameter estimates will also be normal. But the latter sampling distributions approach normality as n increases, even if the error distribution is not normal. If you need published references to support what I've said here, see the textbooks by Wooldridge (2021) and Vittinghoff et al (2012) that are mentioned in the slides I have attached.

* Approximate normality is the best one can hope for when working with real world data. See the famous statement by George Box that I have attached below. The implication is that the t- and F-tests for OLS models are really approximate tests when one is using real world data, and the question is not whether we have exact normality or not, but whether the approximation is good enough to make the model "useful" (to borrow a word from another famous statement by Box!).

HTH.

Without a gaze point, all kind of foveated rendering is a static foveated rendering. Some past documents, e.g. Oculus developers previously work implicitly subdivided the image space into different regions with different sampling rates. But such literature is really rare nowadays. More and more techniques are used where gaze-point is the main parameter for good foveated rendering.

You should use a general form of PDE physic to define the governing equation.

Paul Griesberger Thank you so much for your reply! In QGIS also, it was the same as in R. However, I fixed the problem now. For this, I loaded the raster output in the QGIS and added pseudocolor. It worked perfectly now.

Hi everyone, thanks for your feedback! As Javier Zorrilla de San Martin suggested, I have contacted John Dempster. He was extremelly kind and offered different solutions. Basically, he said I should be able to fully operate up to 4 amplifiers due to the limit of 4 analog outputs in these NI cards. In order to connect more amplifiers, one of the 4 outputs should be routed to the extra amplifier stimulus inputs. He also offered to upgrade WinWCP to enable the support of more than 4 amplifiers, which is the current default.

Hi, we are facing the same problems :-(

so far I found nothing similar

If you just want to inhibit the activity of the enzyme, the easiest way would be to add EDTA in excess of the Mg2+ concentration in the reaction.

The quality of video is not enough to say something about rendering technique. Based on the video description it was "created by scientific animator Jim Stanis" and "shows selected pathways in the atlas they created". It can be based on VTK as well as on own rendering framework. As for me, simple line primitives were used for tracks visualization, from totally transparent to opaque for new ROI appearing and with some transparency for old ones. Surely, VTK usage can simplify this workflow.

you can analyze it in Matlab tool and also write c++ code to measure and perform all analysis

The useful theory is death-anxiety related to all mental disorders. There are lots of scales measuring this already. Contact the authors to this paper. They may be on RG:

Author information

Death anxiety is considered to be a basic fear underlying the development and maintenance of numerous psychological conditions. Treatment of transdiagnostic constructs, such as death anxiety, may increase treatment efficacy across a range of disorders. Therefore, the purpose of the present review is to: (1) examine the role of Terror Management Theory (TMT) and Experimental Existential Psychology in understanding death anxiety as a transdiagnostic construct, (2) outline inventories used to evaluate the presence and severity of death anxiety, (3) review research evidence pertaining to the assessment and treatment of death anxiety in both non-clinical and clinical populations, and (4) discuss clinical implications and future research directions. Numerous inventories have been developed to evaluate the presence and severity of death anxiety, and research has provided compelling evidence that death anxiety is a significant issue, both theoretically and clinically. In particular, death anxiety appears to be a basic fear at the core of a range of mental disorders, including hypochondriasis, panic disorder, and anxiety and depressive disorders. Large-scale, controlled studies to determine the efficacy of well-established psychological therapies in the treatment of death anxiety as a transdiagnostic construct are warranted.

Use some graphics tricks to improve the graphics and haptics rendering rate. For example, you can a dense mesh nearer to the tool, and other places sparse mesh will do. The trick depends on your application.

I'm frequently asked by the editor to complete my reviews in 4 or 6 weeks. However, I don't take that long because the actual reviewing process doesn't take anywhere near that long. I like to clear my desk of all tasks as soon as they come in, so I'm usually done with my reviews in about a week. But, I don't think this speeds up the process much because the other 2-3 reviewers take much longer, and then the editor takes some time to make a decision.

you can use different Matlab image processing algorithm to do your work. graphical target direction you can simulate your problem with Matlab problem and design your algorithm in this regard

Interesting project! A few thoughts:

If you simply put your gauge head behind a screen in order to prevent it from being directly hit by metal vapour from the source you should be able to gain reasonable pressure readings.

Thank you so much all.

Hi there,

Bacterial KanR cassette is functional in yeast and therefore promotes resistance to geneticin. You should avoid this selection marker on your plasmid.

I agree with Cam that the people always make the difference and that electing and even appointing good leaders is a challenge. I think the law can help by improving transparency for example requiring open meetings, and access to government records and documents. Laws can also minimize the degree to which nepotism and cronyism are used to filled government positions. Finally the citizens must be actively involved in the functions of government and this may be best accomplished through educating the members of society to become actively engaged and responsible civic citizens.

You will find your answer and much more in any basic source about the graphic pipeline:

The IPCC protocol for estimating waste emission inventories is probably the most straightforward tool. Note, the IPCC protocol only inventories methane as GHG emissions, not carbon dioxide. It does this because the carbon is biogenic and is not thought to contribute to global climate change. Fossil-carbon sources do contribute to global climate change.

The process identifies the amount of carbon that will turn to methane in an open dumpsite. Instead of a first-order decay model, we will simply use a mass balance, meaning all of the GHG emissions occur in the year the waste is placed. Slaughterhouse was may degrade very quickly so this could be a reasonable assumption.

It uses a few parameters.

DOC - degradable organic carbon (the amount of carbon that will biodegrade).

DOCf - the fraction of carbon that will anaerobically degrade (that will form the methane).

F - the fraction of methane in anaerobic gas

MCF - the methane correction factor, to account for some aerobic decomposition that will occur

Borjesson et al. (2009) actually did most of the work for you here. They estimated slaughterhouse waste as part of their emissions inventory.

DOC of industrial waste (mostly slaughterhouse) = 0.12 tonnes C/tonne waste

DOCf = 0.7 (higher than the IPCC default to account for the fact that slaughterhouse waste is likely protein and fat-rich, meaning very biodegradable and has a higher methane yield than cellulosic wastes such as paper.

F = 0.5

MCF = 0.5 (This number I am assuming because open dumping means there is quite a bit of aerobic degradation.) Look at the IPCC guidelines in the link above. You could assume a slightly higher number, such as 0.6.

DOC * DOCf *F * MCF *16/12 (CH4/C ratio) = 0.12 * 0.7 * 0.5 * 0.5 *16/12 = 0.028 t CH4/t waste disposed.

Divide that number by 0.714 and multiply by 1000 (unit conversion) to get 39.2 m3 CH4/t waste.

Alternately, take the 0.028 t CH4/t waste and multiply by the CO2 factor that you would like to use (21, 28, etc. depending on the timescale) to determine tonnes of CO2 generated per tonnes of waste disposed.

Thank you very much for your detailed and helpful answer! This does indeed give some more insight and might just be what I need. Concentrations below 0,05 mg/L are not of to much concern as you correctly pointed out...!

Thanks again!

Here you have it. Good luck!

we normally use PFA 3% followed by 0.1 % Triton x-100 as the first approach. Then, if we see no AB binding we try with methanol or similar..

Still expecting some good replies.

The intrinsic spectrally resolved sensitivity (ISRS) by itself is not a metric like CRI. It is an analysis method developed by Lin et al. to identify wavelength regions that lead to large changes in CRI when spectral energy in those regions is removed from the spectral distribution of the light source being evaluated. They found that removing energy near 444, 480, 564 and 622 nm seemed to result in the largest fluctuations in CRI. More info in the paper by Lin et al. at:

There are several ways of calculating CRI Ra. You can perform calculations by hand, using spreadsheets or computer programs (e.g. Matlab, Phython).

If you alrready measured the spectral power distribution of the light source, and have them in tabular form, you can simply insert them in a spreadsheet which performs CRI calculations. For example, there is one available on the net: bramley.auld.me.uk/406/Calculating%20CRI-CAM02UCS-v2.xls You can plug in your light source spectrum and it gives you the CRI Ra, as well as CRI special colour rendering index for 14 samples, light source CCT and CRI-CAM02UCS.

A different approach is to begin by running Multi-Dimensional Scaling on the same data, and determining whether the fit (stress) will accept a 2 dimensional solution. If so, you can map the clusters onto the MDS.

To answer the question, "With the LEDs having a high CRI values like 90+, is it possible for the Human eye to detect the change?", my preferred reference is:

van Trigt, C. 1997. "Color Rendering, a Reassessment," Color Research & Application 24(3):197-206

wherein the author states, "... when the CIE method was recommended, a number of weaknesses were known to the principal author. Accordingly, only a difference of some five points in the index was considered meaningful. Unfortunately, this provisio was often not kept in mind in practice."

Remember that the CIE metric was developed two decades before the development of tricolor phosphor fluorescent lamps in the early 1980s, when even the best fluorescent lamps had CRI Ra values in the low 70s. With the introduction of white light LEDs in the early 2000s, it became painfully obvious that the CRI metric could not predict color rendering or color preference. We spent almost a decade with CIE Technical Committees TC-162 (which identified the problem) and TC-169 (which failed to agree on a better metric. The IES Color Committee introduced its TM-30 metric a few years ago, and CIE TC-229 recently introduced an almost identical metric. The IES Color Committee is preparing to release a slightly modified TM-30 color rendering metric that will make it compatible with the CIE metric for a truly international standard.

Regardless, the CIE General Colour Rendering Index Ra (to give it its proper name) will undoubtedly survive in the trade literature for decades to come. Given that any light source with a CRI of less than 80 is unacceptable and that increments of less than 5 points are meaningless, we have:

< 80 Unacceptable

80 - 85 Bad

86 - 90 Acceptable

91 - 95 Good

96 - 100 Excellent

unless, of course, the color rendering index is high but the color rendering is still visually terrible.

Is your protein from prokaryotic or Eukaryotic expression systems? 2 mg/ml is the total protein. Did you detect your target protein by SDS-PAGE from the total cell lysate and the soluble fraction of the cell lysate? How was the thickness of the band corresponds to the size of your target protein compared with the bands of other contaminant proteins?

If you have good expression level for your protein, you can use any of the lysis buffers that:

1. do not contain buffer additives inhibiting the activity of your enzyme

2. have a pH range and ionic strength not affecting the stability and activity of your target enzyme

3. do not contain detergents denaturing the enzyme/or affecting the activity of the enzyme

I have some more input abut the design - the cryopump is not in the line of sight and not exposed to the vapor flux which has a cosine ^2 distribution. Further, there is a shielding plate which minimizes metal vapor deposition near the vacuum connector leading to the cryopump. It seems the design has addressed some of my concerns.

what about the chimera

Thank you so much for your answer. 

I belive the standard approach is to paint a sphere with lambertian paint, which you can buy.

Yes, you can. In my book (El color y su medición, Americalee, Buenos Aires, 1978) there is a chapter (VI) paragraph VI.10 in whoch I treated this problem usin the CIE transformation into u,v coordinates the X,Y, Z   for 8 color samples.

Rendering speed computation depends by many variables among which:

- the implementation of the rendering algorithm;

 - the pc which does the rendering;
