I am a bit confused and I need your expertise help in acknowledging whether we should represent the qualitative results in a semi-structured interview in an anonymous way (few, some, many) or report it as specific data, 3 out of 6 for example 50% of respondents... and so on, as I am getting reviewers' comments from different journals, some of whom recommended that in qualitative research numbers should not be stated and to be totally removed, others who found this ambiguous and asked for representing the data from each question as % respondents, I appreciate your clarification in this regard..!
Any recommendations/guidance would be highly appreciated
The word 'representation' has been defined by Derrida as 'reproduction of presentations'. Taking the prefix 're' to mean 'again'.
When representation can only reproduce presences again, how can it reach into the future? Is that not problematic, as the future is not present and can therefore not be reproduced again?
Why is this relevant? The German word 'Vorstellung' (as e.g. in Schopenhauer's Die Welt als Wille und Vorstellung') is made up of 'vor' and 'stellung': for, in front of (or 'fore' as in 'foreground') and to place, to put. Whereas 'Vorstellung' directs someone's orientation foreward, representation casts someone back into the past. Alway. Inescapably, But a Vorstellung will always be in front of you, wherever you turn.
It is easy to relate Vorstellung to the future. As that will be any account, image, presentation of the future to be placed in front of anyone. (This is also why it is different from 'imagination', as you imagine something by yourself, in your head as it were. A Vorstellung kan be imaginary, but also, similar to a play or a performance (also 'Vorstellung') physically outside of yourself in front of you. Imagination cannot).
So sematically Vorstellung can cover times ahead. But can representation?
And what does that mean for communication theory, when its dominant defining concept cannot address the future?

The porosity of sponges was measured by the solvent method. The solvent was chosen as ethanol because of the insolubility of sponges in ethanol. A certain volume of the sponge
was cut accurately. The sample was dipped into ethanol and removed after saturation. The mass of the sample was measured before and after immersion in ethanol. The swelling degree (P) was calculated by the following formula
P=(m2-m1/vXp)X100
where m1 and m2 represent the weight of the sample before and after
immersion in ethanol, respectively. V and ρ represent the sample
volume and the density of ethanol (0.785 g/cm3).
I would like to ask if sample volume V is the volume of ethanol we take to immerse the sponge into it? Can somebody please clear my doubt?
Thank you.

At the end of the 19th century, the ideas of psychophysiology and its rhetorical devices gave rise to a new way of referring to consciousness and the human being. Literature would change along with this scientific revolution. To such an extent that we speak of nervous and sensory literature, psychophysiological literature. Great novels such as The Magic Mountain by Thomas Mann, Ulysses by James Joyce, In Search of Lost Time by Marcel Proust, and Azar by Joseph Conrad have as one of their central issues the conditioning of these new ways of saying consciousness.
In recent decades, scientific research around consciousness continues to change paradigms, but the reception by the literature of the rhetorical devices of behavioral neurology, cognitive sciences, and others has been slow to come.
It is possible to consider that new literature is approaching based on this new conception. Is neural or predictive consciousness literature approaching? Is there an example? Or simply, Is it impossible for the literature of this step?
We lose memory with time. So, at the age of 50 how much memory of events and people have you lost ? What is the probability and set theory representation of this event ? Is it possible to remember only what you need to remember at the age of 80: both people and events ?
I am trying to encode a classical image of size 512*512 gray image into the quantum image like NEQR (Novel enhanced quantum image representation), and GQIR (General quantum image representation), but I can't find any method to encode in quantum image by which I can apply quantum operation on quantum image to generate the quantum image encryption algorithm. Can anyone give me some hints about how to encode the classical image into a quantum image? It will be very beneficial for me.

The Pauli group is a representation of the gamma group (higher-dimensional matrices) in three-dimensional Euclidean space.

Karen Celis and Sarah Childs argue that "[i]nclusive representation requires presence but also richer political conversations, broader political agendas, meaningful accountability, and feelings of affinity, connection, and recognition."
Their recommendation for reaching this ideal, even if partially, is to institute offices for "affected representatives" in (I would think) all legislatures. These affected representatives would be selected by their communities, who are peoples most affected by for example a proposed policy in some parliament, and would collaborate as equals with regular representatives of said parliament on the development of that policy.
I'd like to invite readers to build on Celis and Child's ideal here.
For my part, I would want local governments to do more - especially with easily defined communities (apartment/condo buildings and neighbourhoods for instance) - to get people talking about public affairs, especially those most affecting them. This is a perennial topic in democracy studies/political theory but neoliberal cultures have made the problem much worse as people withdraw, or are forced to withdraw, ever more into their private concerns. These people withdraw without understanding that neoliberalism does come with an ethical catch: as states weaken, and their services diminish, it is for individuals and their businesses to fill this gap. Only most do not do this and there are, of course, tremendous problems when it comes to corporations filling in for the state.
What are your ideas? What are their limits? How could they work?
Given: x = 10sin(0.2t), y = 10cos(0.2t), z = 2.5sin(0.2t) (1)
There exists the following mathematical relationship:
u = x'cos(z) + y'sin(z),
v = -x'sin(z) + y'cos(z), (2)
r = z'
How to express rd=[x,y,z,u,v,r]' in the form of drd/dt = h(rd), where the function h(rd) does not explicitly depend on the time variable t?
My approach is as follows:
From (2), we have:
x' = ucos(z) - vsin(z), y' = usin(z) + vcos(z), z' = r (3)
with initial values x(0) = 0, y(0) = 10, z(0) = 0
From (2), we have:
u' = x''cos(z) - x'sin(z)z' + y''sin(z) + y'cos(z)z',
v' = -x''sin(z) - x'cos(z)z' + y''cos(z) - y'sin(z)z',
r' = z''
By calculating based on (1), we obtain:
x' = 2cos(0.2t) = 0.2y
x'' = -0.4sin(0.2t) = -0.04x
y' = -2sin(0.2t) = -0.2x (4)
y'' = -0.4cos(0.2t) = -0.04y
z' = 0.5cos(0.2t) = 0.05y
z'' = -0.1sin(0.2t) = -0.01x
Substituting x', x'', y', y'', z', z'' into (4), we get:
u' = -0.04xcos(z) - 0.2y * 0.05ysin(z) - 0.04ysin(z) - 0.2x * 0.05y*cos(z)
v' = -x''sin(z) - x'cos(z)z' + y''cos(z) - y'sin(z)z'
r' = z''
with initial values u(0)=2, v(0)=0, r(0)=0.5
The calculation process is accurate, but is the problem-solving approach correct?

Dear community,
I am conducting research on media representation and I am using the topic modeling technique. To visualize the models I have used pyLDAvis, which is very useful to explore the topics. I would also like to segment the topics into clusters, as they do in the original paper (Figure 4 : https://www.researchgate.net/publication/265784473_LDAvis_A_method_for_visualizing_and_interpreting_topics/figures).
However, my visualizations do not give me that option. So how can topics be segmented into clusters with LDAvis or pyLDAvis? Any idea or suggestion will be appreciated.
Thank you very much in advance

Chers collègues, comment analysez-vous ce type de données ?
C'est une distribution très asymétrique.
J'ai fait 2 transformations pour diminuer l'influence des données extrêmes : Racine carrée puis cubique. Pas de logarithme car j'ai beaucoup de valeurs 0.
1) Le premier graphique en partant du haut représente la variable originale, très asymétrique.
2) Le graphique du milieu, la même variable mais transformée avec la racine carré.
3) Le graphique du bas, la même variable mais transformée avec la racine cubique.
Le trait rouge représente la moyenne et le trait bleu la médiane.
Comment procédez-vous pour analyser ce type de distributions très asymétriques ? (j'ai des valeurs extrêmes à 8 écart-types).

Dear Researchers.
I am trying to resolve the following physical problem. using ANSYS 2021 r1.
Electromagnet that has a coil of 165 turns and 0.0031H and powered by 25 A (AC/DC pending on need) that attract and release a plate standing parallel to it.
I tried to use ANSYS magneto-static to represent the flux density and the force so I made the structure of an electromagnet represented in the picture attached
Running ANSYS magneto-static result in fail due to the following error, despite of trying all the suggested solution yet I am still facing the same issue. (Picture attached)
I tried to switch to ANSYS Maxwell but I could not run it as I had the following error and for the same case I used all the suggested solution about the license and nothing worked.
Please advice



Agarose gel electrophoresis was run on samples of cDNA obtained from RT-PCR with specific primers, and scans of gel were analysed in Biorad.
I'm having trouble ascertaining whether the molecular weight estimated in the program is comparable to the desired molecular weight of the genes whose expression I'm analysing.
For eg. gene X is 511 bp, bands observed from two samples in gel is approx. 484 bp and 521 bp (when compared to MW ladder)
Can these values be comparable to the desired 511 bp and thus represent gene X or not?.
I understand they are observed as not the same molecular weight but to what degree can I chalk that up to how well the gel was loaded and run.

Dear all,
I am going to conduct online-studies about how sounds are represented visually by sketches.
Do you have an opinion, on what to consider when studying sketch-based associations of sound? (I do not want to go in the depth of my own conclusions, as I do not want to bias answers, or if someone wants to take part in the online study.)
What influence may have sketching types, or listening modes?
If someone took part: What is your impression; is something "missing" to care about?
Many Thanks - cheers, lars
Physics is a scence of representations, with mathematical aspects in them, foremost and not of naked correlations and parameter analysis.
It also has competent conceptualizaions, genious principles.
Even the innocent seeking uniform motion is a representational scheme fo motions under the theory of kinematics. (Representations are seperate from reality but are invaluable part of scientific infering, predicting, explaining etc) i.e heat is represented as a flow between subsystems. Representations change i.e Einstein found the curved spacetime one for gravity phenomena.
Physics is also the science f cosmology. It has no meaning if it bypasses the universe-i.e the sum of subsystems. This discipline has problems because we cannot take ourself out of it and study it but physics has tools for this (QM) or theoretical approximaions (more cognitively open consideration of the concept of boundary conditions).
Hej!
I made a corn growth experiment with differents biochar treatments, and I would like to assess now the potential of phosphate solubilizing of the different bacteria populations of some pots, in order to compare them.
I learned that the NBRIP medium (Mehta & Nautiyal 2001) might be used, but as I don't want to isolate or identify those, I would need a method that could provide me a semi-quantitativ method to count them, or to assess what they represent on the total population.
Thank you for your responses!

Hello fellow researchers,
I am hoping to get clarity on what an acceptable form of gene encoding would be for a timetable optimization problem using GA. I have to encode time slots, courses, room numbers and days of the week as genes to form chromosomes that would represent my initial population.

With an expectation that machine-readable tables of structured experimental data add research value.
The ASCII smaller text set null character is an escape zero “\0” or 0x00 digital hash.
The full Unicode character set is consistent as linked to binary and contains a null character where null is U+0000 with symbol U+2400 (and is used as a string terminator in the C programming language).
Given digital information can be of different types (such as string or numeric among others), and that the value of zero is not null, still previous and active sentinel null character representations include the “-9999” and “NA”. Yet a control character requires a unique binary hash designation to be consistently stable. I have recently seen regular non-standard data error values returned including, “NAN”, “ERR”, and “INF”, among others (Excel has a #NAME? construct, and there is the SQL regular NULL). Software de facto handles data type and memory allocation because each data element type is comprehended into different memory configurations and sizes at run time.
In Python, the generic data object type is None or a NoneType, where the included 1985 standard numerical IEEE 754 floating-point representation is NaN.
In NumPy, the typical np.nan provides for the None, including the positive and negative infinity, and the not a number designations.
NumPy is the basis for the Pandas DataFrame None representation, which automatically converts across the object and number (until a native Pandas Null emerges).
HiL simualtions are now being promoted as fast and accurate validation of power electronics systems. For ex., I have used Plecs+RT box for validating the performance of some converters. However, I have a question, what are the practical relevance of the HiL tests ??
In other words, what is the added value of the HiL results compared to what could have been achieved with a detailed offline simulation ? (considering representation of all relevant delays, discrete time implementation of the control loops etc. as can be easily included in any offline simulation in similar ways as in the real-time simulation)

Hello
I was wondering where to add the asterisk on a bar graph representing proportions of a three-levels ordinal variable in 2 groups. The Mann-whiteny U test that I use to detect if there is a significant difference between both groups does not specify which level of this ordinal variable is significantly different in both groups, instead, it gives a judgement on the whole picture (the distribution of the 3 levels of the ordinal variable). So, when I try to represent this in a bar chart, I'm confused where should I put the asterisk??

Hi Hello researchers! need help. I had prepared a cereal-based fermented drink, keeping sensorial properties in mind I centrifuged the sample and collected the supernatant.
And the further analysis was carried out in the supernatant. Antioxidants assays {DPPH/FRAP}. How do I represent the results? Some say it has to be in w/v some say only volume rep eg 500microL but usually in articles we see w/v . And IC50 also is in w/v
So how do I represent this? Thanks in advance....
Greetings dear collegues,
my question deals with representation of "directional" mass and damping in ANSYS Worbench.
In detail, I need to represent the added mass and the radiation damping of an offshore structure and I have find out that commands MATRIX27 and MASS21 may serve to this purpose. Additional mass, indeed, are not sufficient, since they would have the same value in all the three directions, while added mass depends on x-y-z.
Unfortunately, I am not an expert user of Mechanical APDL module of ANSYS and I need to work only with Workbench, where such instructions may be given through the "Command" item, whitin the "Solid Body" tree.
May someone give me some simple explanation on the instructions to give in the "Command" text (e.g. a template) to represent a mass and/or damping symmetric matrix associated to this body'?
Thank you very much in advance,
