Questions related to Connectivity
🟦PURPOSE OF THE OPEN QUESTION🟦
Consulting out of simple scientific curiosity, the immense mass of alternative (and not self-excluding) explanations on the real origin of the contemporary myth of Nessie or the Lochness Monster, the following explanations are certainly worthy of interest...
--geological origin of the phenomenon (Earth System Processes - Global Meeting, June 24-28, 2001. SEISMOTECTONIC ORIGINS OF THE MONSTER OF LOCH NESS. https://www.researchgate.net/figure/1_fig650_346931099 );
--origin from groups of European eels https://en.wikipedia.org/wiki/Loch_Ness_Monster#Eels or from a massive catfish https://en.wikipedia.org/wiki/Loch_Ness_Monster#Wels_catfish
--very interesting Wade https://jeremywade.co.uk/about thesis about the Greenland https://en.wikipedia.org/wiki/Loch_Ness_Monster#Greenland_shark shark.
In this open question, a further zoological explanation is added, which would be interesting to bring to the attention of the scientific community and/or enthusiasts, in order to complete and expand the cryptozoological puzzle of Nessie.
This open question arises from the fact that one of the main morphological characteristics of some descriptions of Nessie's silhouette concerns the structure of the head https://upload.wikimedia.org/wikipedia/commons/thumb/1/13/Loch_Ness_monster_views.svg/800px-Loch_Ness_monster_views.svg.png decidedly rounded and not comparable to that of a plesiosaur, an eel, a catfish, a Greenland https://en.wikipedia.org/wiki/Greenland_shark Shark.
Therefore the first morphological characteristic sought was that of a head that was not elongated and flat but rounded and globoidal.
The second characteristic is that the dimensions must be at least those of an adult human and certainly not those of an eel or a catfish, however corpulent they may be.
The other characteristics that were searched for in association with the previous ones are:
--body length of at least 2m;
--very tapered body shape;
--grey / dark gray body color;
--dorsal fin absent;
--teeth present and clearly visible-recognizable;
--presence in Lochness Lake https://maps.app.goo.gl/jBMknT45dQn8woWr5 and/or the adjacent River Ness https://maps.app.goo.gl/mjNnhfA6bdutqYwV8 which connects the lake to the Moray Firth https://maps.app.goo.gl/XwuuGeLT6BSgYDKM8 (including the sea in front https://maps.app.goo.gl/FmnfheeNDzzbgubT6) with detailed historical or recent references.
🟦Delphinapterus leucas as Nessie??🟦
The relatively recent sighting of a beluga dolphin Delphinapterus leucas (Pallas, 1776) in the River Thames (2018) pushed me to carry out a series of preliminary bibliographic searches in order to evaluate whether or not the characteristics of the beluga itself match those of Nessie. Beluga has..
..rounded head https://en.wikipedia.org/wiki/Beluga_whale#Head_and_neck and mobile neck;
..absence of dorsal fin https://en.wikipedia.org/wiki/Beluga_whale#Fins not even outlined;
..tapered body and https://en.wikipedia.org/wiki/Beluga_whale#Size over 2 meters long;
..teeth present and well https://en.wikipedia.org/wiki/Beluga_whale#/media/File:Delphinapterus_leucas_beluga_MNHN.jpg recognisable-individuable.
The problems to overcome in order to associate some Nessie sightings with the beluga dolphin, would be:
The coloration in young specimens https://en.wikipedia.org/wiki/Beluga_whale#Colour is grey-brown; therefore it is very plausible that rare and large animals could be over 2 meters long and of an unusual color (grey-brown-dark); furthermore, medium-large specimens with undoubtedly dark https://www.researchgate.net/figure/fig97_346931099 coloring are regularly captured. So this element would also theoretically be overcome.
The beluga dolphin spends part of the year near fjords https://en.wikipedia.org/wiki/Beluga_whale#Habitat and river estuaries. So also this element would theoretically be overcome.
Several specimens have been spotted in the marine area connected to the Moray fjord
Balintore sea .. https://www.researchgate.net/figure/fig689_346931099
which makes the main obstacle, that of possible presence near Lochness lake, easily overcome.
Recent sightings of beluga dolphins have also been made in the rivers:
Amur, Hillsborough, Kuskokwim, Nelson, Saguenay, Seine, Thames..
confirming the previous point.
There have even been documented lake sightings, such as:
The elements characterizing the beluga associate quite well with some of the overall characteristics of Nessie and in some cases even better than the zoological explanations so far attributed to the Lochness Monster.
The beluga also reveals itself as an authentic unexpected guest of deep fjords, estuaries, rivers and lakes in numerous locations in the seas of the northern hemisphere, in some cases generating local mini-legends similar to Lochness but not as famous as it.
In the current state of the accumulated data, the ""Nessie as Beluga Whale hypothesis"" appears not only well-founded but also one of the most plausible: serpentine body; absence of dorsal fin; globoidal head, mobile and with evident teeth; grey-brown body, at least during part of life and also for medium-large specimens; overall length 300-600cm; sightings coinciding with the Moray Firth area; not rare sightings in lake environments hundreds of km from the open sea.
To these listed data, others are added which can actually further mislead the identification of a dolphin in a lake:
--the beluga does not have the behavior of jumping out of the water;
--the beluga swims slowly and during emergence from the water surface it rarely exposes its tail, which therefore remains under water unlike its back, which instead forms at least a well-pronounced and visible hump;
--mature and large belugas have lateral expansions of the body which give them a much larger and broader shape when viewed from above https://www.researchgate.net/publication/237064254 a characteristic which could further increase the confusion with the real type of animal (Nessie-like??). Further data will be necessary, even if the evidence produced so far appears robust.
Il Mostro di Lochness potrebbe essere la risultante anche di avvistamenti lacustro-fluviali di beluga (Delphinapterus leucas)??
🟩SCOPO DELLA OPEN QUESTION🟩
Consultando per semplice curiosità scientifica, l'immensa mole di spiegazioni alternative (e non auto-escludenti) sull'origine reale del mito contemporaneo di Nessie o Mostro di Lochness, certamente degne di interesse sono le spiegazioni seguenti ..
--origine geologica del fenomeno (Earth System Processes - Global Meeting, June 24-28, 2001. SEISMOTECTONIC ORIGINS OF THE MONSTER OF LOCH NESS. https://www.researchgate.net/figure/1_fig650_346931099 );
--origine da gruppi d'anguille europee https://en.wikipedia.org/wiki/Loch_Ness_Monster#Eels o da un massiccio pesce gatto https://en.wikipedia.org/wiki/Loch_Ness_Monster#Wels_catfish;
--interessantissima tesi di Wade https://jeremywade.co.uk/about dello squalo https://en.wikipedia.org/wiki/Loch_Ness_Monster#Greenland_shark della Groenlandia.
In questa open question si aggiunge una ulteriore spiegazione di tipo zoologico, che sarebbe interessante porre all'attenzione della comunità scientifica e/o di appassionati, al fine di completare ed ampliare il puzzle criptozoologico di Nessie.
La presente open question nasce dal fatto che una delle principali caratteristiche morfologiche di alcune descrizioni della silhouette di Nessie riguarda la struttura del capo https://upload.wikimedia.org/wikipedia/commons/thumb/1/13/Loch_Ness_monster_views.svg/800px-Loch_Ness_monster_views.svg.png decisamente arrotondata e non assimilabile a quella di un plesiosauro, una anguilla, un pesce gatto, uno Squalo https://en.wikipedia.org/wiki/Greenland_shark della Groenlandia.
Pertanto la prima caratteristica morfologica ricercata è stata quella di un capo non allungato e piatto ma arrotondato e globoidale.
La seconda caratteristica è che le dimensioni devono essere almeno quelle di un umano adulto e non certamente quelle di una anguilla o di un pesce gatto, per quanto corpulenti.
Le altre caratteristiche che sono state ricercate in associazione alle precedenti, sono:
--lunghezza del corpo di almeno 2m;
--forma del corpo molto affusolata;
--colorazione corporea grigio / grigio scura;
--pinna dorsale assente;
--denti presenti e ben visibili-riconoscibili;
--presenza nel lago di Lochness https://maps.app.goo.gl/jBMknT45dQn8woWr5 e/o annesso fiume Ness https://maps.app.goo.gl/mjNnhfA6bdutqYwV8 che lo collega al Fiordo di Moray Firth https://maps.app.goo.gl/XwuuGeLT6BSgYDKM8 (mare antistante incluso https://maps.app.goo.gl/FmnfheeNDzzbgubT6 ) con circonstanziati riferimenti storici o recenti.
🟩Delphinapterus leucas as Nessie??🟩
Il relativamente recente avvistamento di un delfino beluga nel fiume Tamigi (2018) mi spinse ad eseguire una serie di ricerche bibliografiche preliminari al fine di valutare l'aderenza o meno delle caratteristiche del beluga Delphinapterus leucas (Pallas, 1776) stesso a quelle di Nessie. Il beluga difatti possiede ..
..testa arrotondata https://en.wikipedia.org/wiki/Beluga_whale#Head_and_neck e collo mobile;
..assenza di pinna dorsale https://en.wikipedia.org/wiki/Beluga_whale#Fins nemmeno accennata;
..corpo affusolato e https://en.wikipedia.org/wiki/Beluga_whale#Size lungo ben otre 2 metri;
..denti presenti e ben https://en.wikipedia.org/wiki/Beluga_whale#/media/File:Delphinapterus_leucas_beluga_MNHN.jpg riconoscibili-individuabili.
I problemi da superare per associare alcuni avvistamenti di Nessie al delfino beluga, sarebbero:
La colorazione negli esemplari giovani https://en.wikipedia.org/wiki/Beluga_whale#Colour è grigio-bruna; pertanto è ben plausibile che rari animali e di grandi dimensioni possano risultare di oltre 2 metri e di colore inusuale (grigio-bruno-marrone); inoltre vengono regolarmente catturati esemplari di medio-grandi dimensioni dalla colorazione indubbiamente https://www.researchgate.net/figure/fig97_346931099 scura. Quindi anche questo elemento sarebbe teoricamente superato/superabile.
Il delfino beluga trascorre una parte dell'anno in prossimità di fiordi https://en.wikipedia.org/wiki/Beluga_whale#Habitat ed estuari fluviali. Quindi anche questo elemento sarebbe teoricamente superato/superabile.
Diversi esemplari sono stati avvistati proprio nell'area marina connessa al fiordo di Moray..
il che rende agilmente superato proprio l'ostacolo principale, quello della possibile presenza
Recenti avvistamenti di delfino beluga poi sono stati effettuati nei fiumi:
Amur, Hillsborough, Kuskokwim, Nelson, Saguenay, Senna, Tamigi..
confermando il punto precedente.
Addirittura ci sono stati documentati avvistamenti lacustri, come:
Gli elementi caratterizzanti il beluga si associano abbastanza bene con alcune delle caratteristiche complessive di Nessie ed in alcuni casi anche meglio delle spiegazioni zoologiche finora attribuite al mostro di Lochness.
Il beluga inoltre si rivela come un autentico ospite inatteso di fiordi profondi, estuari, fiumi, laghi di numerose località dei mari dell'emisfero nord, generando in alcuni casi mini-leggende locali analoghe a Lochness ma non famose come essa.
Allo stato attuale dei dati accumulati, l'ipotesi Nessie as Beluga Whale appare non solo fondata ma anche una delle più plausibili: corpo serpentiforme; assenza di pinna dorsale; capo globoidale, mobile e con denti evidenti; corpo grigio-bruno, almeno durante una parte della vita ed anche per esemplari di medio-grandi dimensioni; lunghezza complessiva 300-600cm; avvistamenti coincidenti con la zona del fiordo Moray Firth; non rari avvistamenti in ambienti lacustri a centinaia di km dal mare aperto.
Ai dati elencati se ne aggiungono altri che effettivamente possono fuorviare ancor più l'identificazione di un delfino in un lago:
--il beluga non ha il comportamento di saltare fuori dall'acqua;
--il beluga nuota lentamente e durante le emersioni raramente espone la coda, che pertanto permane in acqua a differenza del dorso, che invece forma almeno una gobba ben pronunciata e visibile;
--beluga maturi e di grande taglia, presentano espansioni laterali del corpo che gli conferiscono una forma molto più larga e ampia in visione dall'alto https://www.researchgate.net/publication/237064254 caratteristica che potrebbe ulteriormente aumentare la confusione con la reale tipologia di animale (Nessie-like??). Ulteriori dati saranno necessari, anche se gli indizi finora prodotti appaiono robusti.
In one of our fiber photometry rigs, there is a pigtailed rotary joint connected to an FC-FC mating adapter (flange 11mm) that is then connected to our fiber optic patch cord. The problem is, the light transmission out of the pigtail is around 90 uW, and the adapter is pretty much the same, but then when we measure light transmission out of the fiber optic patch cord its around 20-30 uW. Is there any way to better optimize this region to get a higher light output?
I am trying to set up a Graphab project and to calculate a linkset. This works fine when using a small crop of the original research area with an external raster file containing resistance values, or when assigning some class-specific resistance values. However, when I use the full extent of the map in combination with an external raster file that contains the resistance values, I get the following error:
"java.lang.RuntimeException: java.lang.IllegalStateException: Negative or null cost is forbidden. Check your cost."
There are no null or negative values in the resistance raster, so what shall I make of this message? Could it have been caused by some other issue not accurately reflected in the error message?
I have deep neural network where I want to include a layer which should have one input and two outputs. For example, I want to construct an intermediate layer where Layer-1 is connected to the input of this intermediate layer and one output of the intermediate layer is connected to Layer-2 and another output is connected to Layer-3. Moreover, the intermediate layer just passes the data as it is through it without doing any mathematical operation on the input data. I have seen additionLayer in MATLAB, but it has only 1 output and this function is read-only for the number of outputs.
I'm simulating a simplified bolt connection between two parts. I made the bolt without a thread, as it was done in most forum posts here. However, I do not have a bolt-nut connection, but I screw the bolt directly into a hole (the hole is also simplified without a thread).
What interactions do I have to make with the screw shaft and the hole? I tried it at the beginning with tie-constraints, but I got errors because there was an overlap with the bolts pre-tensioning. In addition, I tried contact, where I defined the tangential behavior as rough. Unfortunately, without success.
Any of you have an idea for this problem?
Thank you very much for your efforts!

I have started to work on my research project and I actively search for information on measuring electrification charges.
In the future I have to measure the charge of a tube with a fluid being pumped through it (a conductive tube connected to non conductive ones, the fluid is also non conductive, but will have some conductive additives).
I found a lot of theoretical works, but can't seems to find practical examples or equipment to use. The stuff I found are barebone depictions like: "There is a grounded tool installed along the pipe, that measures the charge", with no links to the source.
So I need some help to find methods and tools I can use to mesure the electrification charges.
I need help modelling horizontal BNWF with axial, transverse, and vertical (bearing & uplift) springs and spring damper at the ends to simulate connectivity.
I want to know how I can model these on to the beam and assuming the pipeline segment is 1 kilometer in length, at what intervals should the soil springs be applied? Can we assign line springs in OpenSees?

Scientific results, at least those generated by individuals holding positions at universities or at publicly financed research institutes, should be openly accessible to all people worldwide.
In order to be able to access a publication, often a fee will be charged by the publisher. For open access publication the authors have to pay quite a lot of money, and many researchers are simply not able to achieve this. Certainly the main community of researchers is not at all happy with this situation.
During the last decades, publishing -- fortunately ! -- changed from costly print versions to much cheaper electronic versions. Meanwhile it is quite easy to set up an electronic journal and ... to make money with such a business ! Not rarely a publisher tends to not taking peer review seriously, since rejecting a submission means less income. Quite a number of journals and publishers have meanwhile even been classified as "predatory" and an author should better check carefully, to which journal she/he should submit her/his work.
Let me briefly report a case, in which I have been -- and I am still -- involved. The original publisher of the Journal of Generalized Lie Theory and Applications (GLTA) was Astralgo Science in Estonia. In those days I was asked to join the Editorial Board. Later this journal moved to Ashdin Publishing, then OMICS and finally Hilaris, alleged "predatory" publishers according to quite a number of sources in the internet. Apart from a strange description under "About the Journal", on the GLTA website
"Fast Editorial Execution and Review Process (FEE-Review Process)
Authors who are willing to publish their articles under this mode can make a pre-payment of $99 towards express peer-review and editorial decision. First editorial decision in 3 days and final decision with review comments in 5 days from the date of submission."
It should be obvious to any serious scientist, that this is not compatible with any reasonable peer review process. I asked the publisher to remove my name from the Editorial Board and at least one of the Editors-in-chief followed me. No response at all and no action. Lately GLTA even published total nonsense articles under the name of respectable scientists who had nothing to do with it !
Long ago I had rejected several submissions to GLTA that landed on my desk. But since many years I have not received anything anymore from the editorial office. The editors-in-chief should know, which of the published papers actually went through a peer review process.
Authors in general have to transfer copyright to the publisher and lose their own right in this way.
Why we should not pay publication fees and also not fees for open access publishing
As the above example in my opinion clearly shows, this could drive the publisher to decrease the level of scientific quality.
It is also not understandable that an author has to pay for keeping the right to her/his own work.
What shall we do ?
A major revolution in scientific publishing has been the creation of the arXiv by Paul Ginsparg in 1991. Of course, we also have to thank Donald Knuth for his ingenious TeX and Leslie Lamport for the somewhat more user-friendly LaTeX.
We should only take submission to a journal into consideration, if the publisher allows us to store a corresponding preprint version in the arXiv. There are even journals (like Communications in Mathematical Physics) which require that authors send their work to the arXiv prior to submission.
Posting in the arXiv also allows other scientists to send private comments to the authors, which offers a chance to improve their work. I'm typically waiting at least a month from arXiving a paper to submission to a journal.
Some authors send their work from one publisher to the next until it gets published somewhere, without prior posting in the arXiv. This occupies editors and referees and should not be considered a decent scientific behavior in my opinion. Isn't it a bit sneaky ?
The availability of a preprint version (which can even be updated) in the arXiv makes payment for open access publishing redundant, in my opinion.
How to maintain scientific quality ?
Sure, the arXiv is a great thing, but we do need services to maintain and increase scientific quality.
There are "overlay journals" like SIGMA, strongly connected with the arXiv. Perhaps this is a substantial part of the future of publishing.
In my opinion, a good quality of scientific publishing can in fact only be achieved via a good editorial board, which has full rights to decide about publication or rejection. There are certainly also questions concerning the way of constituting an editorial board, election of members, choice and quality of referees, etc. But this is a more restricted problem.
If we are asked to join the editorial board of some journal, we should think twice and check the journal carefully. If it makes a good impression, this does not mean that this will be so forever. In particular not if there is a publishing business behind it.
But the publishers need financial support to maintain servers, infrastructure, editorial services
First, we should not forget that also the arXiv needs funding ! It seems that the system works well presently, but perhaps the scientific community should support it even more.
In my opinion, scientific publishing, as a business and at least in the realm of journals, has no future. More public funding will be necessary to establish and maintain an independent academic publishing structure.
Clearly a lot has already been written about scientific publishing and the problems connected with it. I did not read it all, sorry ! But I do hope that I did not miss some of the most important aspects.
Take care !

Physics is a game of looking at physical phenomena, analyzing how physical phenomena changes with a hypothetical and yet mathematical arrow of time in 3D space, namely by plotting that physical phenomena with a mathematical grid model (typically cartesian based) assuming that physical phenomena can be plotted with points, and then arriving at a theory describing that physical phenomenon and phenomena under examination. The success of those physical models (mathematical descriptions of physical phenomena) is predicting new phenomena by taking that mathematics and predicting how the math of one phenomenon can link with the math of another phenomenon without any prior research experience with that connection yet based on the presumption of the initial mathematical model of physical phenomena being undertaken.
Everyone in physics, professional and amateur, appears to be doing this.
Does anyone see a problem with that process, and if so what problems do you see?
Is the dimension of space, such as a point in space, a physical thing? Is the dimension of time, such as a moment in time, a physical thing? Can a moment in time and a point of space exist as dimensions in the absence of what is perceived as being physical?

In recent years, the use of psychedelics in mental health treatment has garnered significant attention, with promising research indicating their potential to aid individuals with various mental health conditions, including depression, alcohol-use disorder, anxiety, and PTSD. These substances, often referred to as entheogens, have the ability to induce altered states of consciousness, leading to profound and transformative experiences. This resurgence in the mental health field has prompted questions about how traditional models of psychiatry, psychology, and psychotherapy have addressed the concepts of imagination and spirituality, particularly concerning the potential development of spirituality through experiences that explore the realm of the imaginary.
It is noteworthy that delving into the imaginary and spiritual dimensions of human experience may offer individuals fresh insights into self-understanding, emotions, and connections with others. This has resulted in a shift away from rigid reductionist approaches towards a more comprehensive understanding of mental health and overall well-being.
Though psychedelic-assisted therapy is still in its early stages, ongoing research suggests that these substances, when used responsibly and in controlled settings, hold unique opportunities for personal growth, self-discovery, and healing. Integrating these experiences with modern therapeutic techniques could pave the way for more effective mental health treatments.
As mentioned in the text, the use of current technologies to measure the effects of these experiences represents a promising avenue for further exploration and validation. Research in this area has the potential to establish a stronger scientific foundation for the use of psychedelics in mental health treatment, ultimately benefiting those who can gain from these therapeutic approaches.
Overall, the renewed interest in exploring the connections between imagination, spirituality, and mental health, coupled with the potential advantages of psychedelic-assisted therapies, presents an exciting and continually evolving field of research and application in the realm of mental health care.

Is it necessary to have short connection lengths between regions of favourable and unfavourable curvature for an optimized stellarator to prevent MHD-instabilities? I have seen this opinion in multiple papers but have not found a detailed assessment of it.
This opinion can be found in Horst Wobig 1999 Plasma Phys. Control. Fusion 41 A159,
4. MHD stability of stellarators
"The main factors determining the stability limit are magnetic well, small Pfirsch-Schlüter currents, small field line curvature and small connection lengths between regions of favourable and unfavourable curvature."
"The aspect ratio A = 12 is determined by the MHD-stability limit, which demands short connection lengths between regions of favourable and unfavourable curvature of the field lines, and therefore, tends to increase the number of field periods."
Please tell me, is there a difference between testing a four-port device directly with a four-port VNA and testing a four-port device with a two-port VNA with the other two unexcited ports connected to matched loads?
When I tested the differential line, I used a two-port VNA because I didn't have a four-port VNA, but the reflection coefficient of the test result was much worse than the simulation result, going from below -15dB in the simulation to only staying below -10dB. In my simulation, however, I added the SMAs at exactly the same dimensions as in reality, and the simulation showed that the reflection coefficient would not be as bad as the test results.
I am trying to do a impact analysis through workbench explicit dynamics.
I establish the model in Explicit Dynamics and mesh it at first, and then, I go back to the project schematic page and drag the Autodyn component into there. Then, I connect Autodyn and Explicit Dynamics two parts together. I click the " setup" icon in Autodyn part and update it. Later, I go into the screen of Autodyn and find nothing in there. I attach all of my processes in this poster. Is there any body could tell me how to import the model in Explicit Dynamics in Autodyn?

We have a few potentiostats in our lab, with different working voltage (or control voltage), and compliance voltage specifications. e.g. SRS EC301 lists +/- 15 V working voltage and +/- 32 V compliance voltage. We are able to take our working electrode till 15 V and the voltage between working/counter till 32 V. Likewise for Parstat or Versastat.
In the case of biologic VSP 300, with 1A/48V booster, we are able to take the working electrode till 48 V (just as a test), but the reference to counter voltage maxes out at 10 V, and flags overload at higher voltages. What we learnt from the company is that this is a part of the design. So, technically the potential between working and counter can go till 48 V, but the potential between reference and counter terminal cannot exceed 10V, even if the potential between ref and working is (e.g.) 2 V.
So, when we use a cell for CO2RR studies in a H-Cell, with a ion permeable membrane between the chambers, with a working voltage of -2.X V, we hit the overload. To perform chronoamperometric studies, we have found a hack. Since our working voltage is < 10 V, we can connect the actual working electrode to counter terminal, keep the reference electrode near this, and connect the Pt foil counter electrode to the working electrode terminal, and apply the current (with opposite polarity). We can monitor the voltage between reference and counter terminals using a data logger.
However, this trick cannot be used for experiments with potential controls. Have any of you encountered this issue? If you found a way to solve this, can you please share the details?
Thank you in advance!
Can anyone please tell me in detailed explanation what is the difference between the joint and the connection in steel joint?
given that :
joint rotation = total rotation of the beam-end - beam elastic deformation - column elastic deforamtion - block rotation
connection rotation = joint roation - column web in plane rotation + column elastic deformation + block rotation

Going with the definition that "Individual differences are the unique characteristics and traits, which distinguish us from others", would you consider sexual orientation an ID? When researching literature connected to the term "individual difference" sexual orientation does not come up very often in my experience. Mostly values, personality, intelligence or temperament. While sexual orientation does fit a broad definition of an ID, it does not seem to be often connected with the term. Do you consider sexual orientation an ID in the same category as personality or intelligence? Is it perhaps related to tradition, that we do not use ID that often as a descriptor of sexual orientation?
Most of the researchers specially from humanities background do not like social networking site. They do not have any id also. How I can encourage them?
I am trying to design a table (rectangle or circle, doesn't really matter) that will hole an object on the center of it. The table will be connected to a shaft which will be driven by a belt that connected to an engine.
My goal is to rotate the table in a constant angular speed, let's say - w.
The calculation that I did is basically:
F = mw2r
T = r*F = mw2r2
m is the total mass (object + table), r is the radius of the table, w is the angular speed that I want, T is the torque needed.
Now, when I get the needed torque I can choose the engine that can provide enough torque.
Of course I will choose bearings that can hold the weight and let's say the gear will be 1:1.
Is this calculation is right? I added a picture of what I am trying to do, B is bearing, so from the bearing to the top is dynamic and below is static.
My question is, is it a valid way to make an estimation of engine type?
Are there any studies which show that maintaining a strong connection to one's cultural identity positively influences language learning outcomes and overall well-being?

Hi, for my graduate research, I need to analyze a simple bolted connection on ABAQUS. The bolted connection consists of 3 bolts that connects 3 plates (see the picture attached for reference). The top and the bottom plates, is fixed at the end of the plate. The middle plate is loaded with uniform loading on the other end. I've tried to run it, however I get these kind of error
***WARNING: THE SYSTEM MATRIX HAS 3 NEGATIVE EIGENVALUES.
***WARNING: DISPLACEMENT INCREMENT FOR CONTACT IS TOO BIG.
I have tried to make the surface contacts each other in the beginning of the analysis, however it still doesn't works.
I did SEM in AMOS and it suggest to connect an error variable and observed variable to enhance the model fit. I was wondering if these variables can be connected as well as two error variables.
I am a Teacher, i find very hard to collaborate with learners parents to ensure mutual support in managing learners' discipline.
As we are in the era of Technological advancement, I am looking for any emerging Technologies that can help me connect easily with learners parents.
One of the main factors taken into account in architecture is the appearance of a building. The kinetics of the responses connected to the material resistance and the severity of the degrading forces and landscape can all affect how material changes in appearance.
When multiple GaN DHEMTs are connected in parallel, their output currents are combined to provide a higher overall output conductance.
What is the connection between biotic potential and environmental resistance and how does energy flow through an ecosystem?
I am wondering if there is any way to refresh the input data from a dynamic text file in COMSOL for each iteration.
I have attempted to do this in Python, but COMSOL only solves the equation for the first input text file and not for any new files generated. The reason for this is that I have coupled COMSOL with a DEM-based software which feeds the input to COMSOL for each iteration. (same situation for the output to save the results as a text file)
While the connection is established through Python codes, I am unsure if Python can trigger the refresh button for each iteration!!!
Any suggestions would be greatly appreciated.
right now I'm modeling a membrane pack bed reactor.
but I haven't been able to get the appropriate results because I can't connect the effect of the permeation that occurs to the velocity inside the reactor.
is there an equation I can use regarding this?
Regarding the connection between Beha'alotcha story of quail and pandemic COVID-19 punishment from G-d to go vegan is there any Vegan Rabbi who might have asked whether or not there is a connection, or who might like to answer the question since the plague was fairly recent and they might not have noticed the significance of this punishment and just like there having been ten plagues in Egypt, maybe we haven't yet experienced the potential "worst?" plague yet, and more are to come? Can WE do something to avert this imminent prediction or just go back to business as usual? Are we paying heed to G-d's warning and are we to take this seriously and stop being punished when we finally learn our lesson? Does any Rabbi wish to be interviewed on this topic within a reasonable period of time from the posting of this question? In a mere four-days'-time I shall give a PowerPoint presentation at Synagogue on this very topic, on the story of the quail in the Beha'alotcha Torah Portion and wish to make the above mentioned points! Thanks for responding.
I have some troubles with the connection of Anritsu MS9740A with LabView via VISA.
I have read the Anritsu datasheet, and they comment that is possible to connect the Anritsu through GPIB and Ethernet but through command communication, they don't tell anything about LabView communication.
I have attached a ZIP with the VI Tree that allow the communication with the OSA, but, firstly when I connect via USB the Anritsu with my PC, I could not observe the instrument in the I/O VISA session. So, I don't know if I need install an additional driver or firmware that allows me the correct communication with the device.
Can you have some advice that can help me with this inconvenient?
Hello. I am trying to implement space vector pwm control for permanent magnet motor. In my work the permanent magnet motor is represented by two 3d look up table based flux maps. I have generated necessary switching signals for the universal bridge block which works as an inverter. My plan is to measure the three phase voltages with three phase V-I measurement block and then use park transformation to convert the abc voltage to d-q voltage values which after some mathematical operation will be inputs to the look up tables. However, I am facing two issues.
(1) I can not connect the output of the three phase VI measurement to a multiplexer through which I can connect the three phase voltages to the abc to dq0 block (as highlighted in the attached image). Is there any converter block required so that they can be connected?
(2) I need to measure the phase voltages (phase to ground). However, in my model there is ground connection. Will I be able to measure the phase voltage?
Can I connect the virtual sensor in NetSim to a cloud server? Is it possible to run a ‘real application’ in NetSim’s virtual sensor and connect it via the internet to a cloud server?
I am a final year PhD student and due to submit my thesis within the next couple of weeks time.
I have adopted political opportunity theory to address union strategy in the developing country in terms of coalition building/solidarity and collective action. Although there are many variables in the political opportunity theory, I have focused on openness and closing opportunity of the institutional political system.
Could you please advise me if this is ok to adopt just one variable or need to discuss all variables in the opportunity structure? To address openness, I discussed organising, servicing, connection, participation, negotiation under coalition building/solidarity and strike/protest under collective action as closing opportunity.
I would appreciate your valuable feedback on my approach/structure of the theory or pls let me know if I need to include anything to bridge any gap.
Finally, I had the chance to produce a new video for the NDE 4.0 YouTube Channel: Artificial Intelligence for NDE and NDT. In this video the Neural Network types for use in NDT & NDE are discussed: convolutional neural networks, fully connected networks, and U-Nets.

In a research paper, they mentioned this phrase "We have noted two numbers of mutation in some positions, which are nucleotide positions at 39,139, 44,220, 61,844, 63,147, 77,807, 132,625, 148,427, 164,832, 165,782, 170,698, 182,189". what are these connected positions refer to?
As shown in the scheme, the laser Agilent 8164A processes the internal modulated waves to the on-chip diode, and the output signal through the RF pad on the chip will be processed to the oscilloscope. The diode works under input from the DC supply, which connects the DC Pad and Ground Pad on the chip. Oscilloscope connects to the RF Pad and ground Pad for receiving the output signal.
Q1: here we will have the ground of the oscilloscope, DC power supply, and on-chip diode connected together. Will it be safe? Can Oscilloscope correctly receive the output?
Q2: Is there any damage possibility that I connect them like this? Such as a potential back-reflection from one of the tools which will possibly cause damage.
Several companies export raw materials to different countries. In return, those countries import finished products from those supplies at high prices.
In your opinion, what hampers these suppliers to connect with SMEs to produce within a country?
who do you think has more challenges upsream (suppliers of raw material) or downstream (SMEs) to adopt this strategy? or any other player? thoughts/suggestions are welcomed. Chers
I wish to join Beam188 and Combin14 elements in ANSYS APDL. Can some one suggest me a suitable contact element to join Beam and COMBIN14 elements.
Thanks & Regards
Lucy J. Parry points out the exclusionary character of "mainstream" democratic theory. Parry writes:
"There is a disconnect between democratic innovations in academic research and practice. Hans Asenbaum and Friedel Marquardt have already pointed out that, to reinvigorate democracy, we need to engage with those who enact it outside academia in their day-to-day work and lives. Practitioners – including facilitators, designers, public servants, NGOs and consultants – have been somewhat neglected in this debate. Yet they are often on the frontline of democratic innovations, and their experience can greatly enhance our understandings of democracy."
For more, see: https://theloop.ecpr.eu/connecting-theory-to-the-messy-realities-of-democratic-innovations-in-practice/
I have discussed Parry's point on and off with colleagues since this essay was published and one of the recurring questions in these discussions is how to connect with practitioners.
Academics are trained in typically exclusive arts that rely on specializing in specific methodologies, adopting certain writing styles, using technocratic language, publishing in specialist outlets, and attending specialist events/developing specialist networks. This does not bode well for collaborating with experts who not only do none of these things but sometimes have little interest in the "high theory" that some democratic theorists promote.
What would be your suggestion for helping democratic theorists to connect with experts outside of academia?
for a paper I am preparing a plot that links source, method of preparation, and application in a circle-like structure. To discuss it here, I prepared a sketch that should be easier to follow without prior knowledge of my specific field of research (see attached Graphic).
The three circle segments represent vegetables, things you can make from them, and places, where this food might be offered. Lines then connect Veggies, preparations, and types of restaurant, that typically go together.
Examples: Sweet potato chips and potato chips are a thing, hence a connecting line (Zucchini chips and pumkin chips not so much). Vodka is made from potatos, but not sweet potatoes, pumpkin, or Zucchini, and it is served in Pubs, and maybe fine dining restaurants, but rather not in Italian restaurants or Fast-food parlors.
Things I like about this plot-type are:
-I find it aesthetically pleasing.
-You can pretty easily identify niche and common entities from the number of lines originating there (like potatoes and soup going with kinda everything, and Zucchini and Vodka being rather picky).
-Following the lines from one entity, you get to all associated entities, making it quite easy to reference neighbors in the network.
-Unlike in a network graph, entities are not spread about the whole network, but neatly organized on the outside for reference and added text.
-Entities are easy to group into categories. More or less categories, than the three in the example would be possible.
In the example, the categories are all underlaid by a primary color (yellow, blue, red) and each line has the secondary color (orange, green, purple) of the categories it connects, to make it easier to follow the lines. However, the information density could be increased further by formatting the color and strength / thickness of lines. For example, you could code a probability or strength of association by a line color or by line thickness, like: How probable is it to find vodka at a fine dining restaurant; coded as color of the connecting line on a red-blue gradient like in a heat-map, or by line strength.
My questions are:
-Is this plot a new thing, or is there a plot type, that's basically the same, that I just don't know about.
-Does it make sense to display information in this way, or is there a more approachable or more aesthetically pleasing way of conferring the same information?
-What to call this kind of plot? My initial thought was cobweb plot, but that's already a thing. I then thought dreamcatcher, doily, or weaving-frame diagram, which don't seem to be taken already. The design is visually inspired by a circos plot, but otherwise doesn't share a lot of similarities. I am hence a bit hesitant, to call it "narrative circos plot" or "Network circos plot".
If you want to use this kind of plot, I'd be super happy to see your work! Would be cool, if you'd reference or link this post.
Also shout-out to Biorender, where I threw this plot together. However, I am sure, you can also make a plot like this with less manual moving of lines and icons, if you know your R (or GIMP or Inkscape for that matter).
PS: Please spare me your comments, that it actually is possible to make Vodka from Zucchini ;-D it's about the graph style, not the specifics for this one. The example graph is not super polished, but you get the picture. Also I think it's clear, that I am not researching the culinary scene, but I found that an easy and accessible example.
These principles are organized under four main themes: variation, selection, connectivity, and eco-evolutionary dynamics. Evolution by natural selection is the inevitable consequence of three simple conditions: variation, inheritance, and differential reproductive success.
