I've read it can be due to 'intrinsic semiconductor conduction' and surface conduction. The LED I am looking at is InAs, which is apparently prone to surface conduction. I have tried out what these two quantities are on google but have been unsuccessful. In particular because I have no extensive mathematical knowledge of the subject, and so am looking for a qualitative answer. And why does reverse leakage current increase with higher temperatures?
Q: Is the italicised verb form correct in this sentence? Jane's pale face suggested she could be ill: her parents suggested that she have a medical examination. A: The sentence is grammatically correct. The subjunctive remains in force even though it is likely the patient will follow the doctor's advice. To actualize the blood test with "has" would be telling an untruth. The subjunctive holds the notion of a suggestion in place. Thus does grammar make its own modest contribution to truthful speaking. I don't see how this sentence can be grammatical. Please could you offer any comments.
I am just about to create my beamer file for my upcoming presentation in which I need to open another program (NetLogo if it helps) to show it to the audience. Is there any possibility to create a shortcut or link so that I only have to press 'next' or click on that shortcut to open the program? Or do I have to close the PDF my self and open the other program? I'd be most thankful for your answers.
I am sure all of us have played with rubbing things and producing static electricity and when I was charging my comb by rubbing it on my hair and watching it attracting a small piece of paper, I heard a very feeble noise just like an electric buzz sound. I could feel the electron "cloud" all around the comb and the paper it I could find no reason as to why a sound should be produced. From where is that sound coming from?
This is a historical question partly, and maybe too broad for this site, but would require some familiarity with modern physics research practice so hopefully appropriate here. Einstein's later years, after general relativity, were (as I understand it) taken up predominantly by his effort to find a unified theory that explains both gravitation and electromagnetism and their interrelation. And from what I understand his approach was mainly mathematical, trying variations of functions and so forth, looking for something that fit - and doing his work predominantly on paper. Had he access to modern computers - programming languages, mathematica, etc. - how might that have changed his progress, and willingness to give up perhaps? And in what ways have computers in general changed / revolutionized theoretical & mathematical physics?
Lately, I have been watching sparks while connecting my electronic devices and I can notice that electricity is kind of blue, and theoretically it's blue because it reflects blue wavelengths?? And that makes it a particle (like if I said that light is a particle because photons). So am I correct? If electricity doesn't have that color because of that, then why is it blue?? After asking this now I think the following questions: Does electricity have the exact temperature to produce blue light (in terms of the EM spectrum)?? If the answer is no, why does electricity have color??
If context is needed, I'm happy to supply it.. The sentence I want to rephrase: Some selection of this kind has for some time been imperatively called for, by the wants of the gardener, farmer, and amateur, the multiplicity of sorts in the larger works and catalogues rendering them nearly useless to those who merely wish to know those kind adapted for family or market supply. I'm at a loss of words for interpreting the sentence into concise rephrasing for elementary comprehension. It's from a book by Robert Buist titled "The Family Kitchen Gardener" (Full book). The sentence is under PREFACE a few paragraphs down.
According to Wikipedia, A set of states C is a communicating class if every pair of states in C communicates with each other. A communicating class is closed if the probability of leaving the class is zero. Would you call an absorbing state a closed communicating class since it cannot be left and it communicates with itself? However, one problem with calling an absorbing state a closed communicating class is that since it consists of only one state (obviously) - and this might not satisfy the definition of a set of states.
English has a "intricate" relationship between graphemes and phonemes,i.e. there is no sure way of knowing how to pronounce something by just looking at its written form. Generally any language has this property, but English is much more complicated in comparison to - say - Italian (which happens to be my native language). This fact is known, and I remember stumbling upon a very nice sentence by an English Author, who leverage on this fact and wrote a sentence whose words did not make any sense together, but if you read them, then the "sounds" formed a perfectly meaningful phrase. I seem to remember something concerning "god" and a "fish"? Not sure though. Anybody remember that?
In a research problem in an unrelated area, me and a student found it necessary to count the number of directed graphs with every vertex having one outward-pointing edge, with no restrictions on the number of edges pointing inward. Not being a graph theorist, I was wondering if this is a well-known class of directed graphs. Is the number of such graphs for fixed n known? If it is unknown or an open problem, we'll work on it together, but it seems likely to be known.
I am writing an ad and would like to write: "Our team of economists are at your service and available by phone or email. They will be happy to respond...". I know that grammatically speaking, 'team' is the subject of the sentence and, being singular, would dictate that 'it' is "at your service". BUT, it just feels better reading this and it evokes a picture of a bunch of economists doing what they do rather than a single unit". Is what I'm doing OK? Should I be arrested by the grammar police?
Possible Duplicate: Temporarily increase line spacing I tried to follow these examples here Temporarily increase line spacing but in my case it didn't change anything. I have to use a latex template, which is provided by my university. My title looks currently like this: as you can see, the third line has not enough spacing. Can anyone help me to fix this issue? You find the entire template (already with my title in it) for downloading on my webspace: http://www.easteregg.ch/DDIS-diploma-thesis-template-en-long-title.zip just run the "ddis-thesis-EN.tex" in the root folder and you will get probably the exact same issue.
Does a first-person possessive pronoun have to come last if it is in a list with others?" "My irresponsible sister loves jewelry, so she took both Sally's and mine. "The same room was marked on Joe's and my map." I know it is much better to simply use a plural pronoun such as our or their, but I can not find the answer to this anywhere.
Situation: Someone says i want to meet the first monday of each month. And i want to tell them that the first wouldn't work. But i want to say it like: Please choose a different xxxxx. IE: if i wanted to change the day i'd say. "Please choose a different day" I'm thinking something close to frequency or ordinal..but i'm sure there's a term for it.
Does a magnetic field have concentrations of magnetic force lines as seen when putting iron filings over top a bar magnet or are these imaginary? I.e. are they just an artifact of the iron being a 'conductor' of the magnetic field lines making them look like they are concentrated along these path lines but are really continuum of strength around the bar magnet when there are no filings are present? Also I learned that field lines do not cross, yet there are magnet configurations who's forces are explained as the magnetic force vectors are indeed crossing and are additive such as a Halbach Magnet Array. So what is actually happening here?
In an airplane, the lady attending you is known as the attendant, besides sometimes being called a stewardess or air hostess. What does she do? Just serve you. Then what is that my maid does? Nothing but serve me. Can I therefore call my maid, my attendant? What about my other servant? Can I call him my attendant too, since I cannot call a male person my maid? Is gender the only difference? Then who and what are pages? I am looking for a clear distinction between these four terms.
So I asked a question earlier similar to this, and the solution made sense; however, the graph was very simple with only five vertices. If the graph is more complex like this one then how would you determine if the graph is a bipartite? When I asked earlier, I was shown the method of trying different color combinations for all the vertices, and checking if the edges connected opposite vertices that way, but is there another way to do it for a more complex graph like this one?
I do understand the concept of Naive Bayesian classification, as it tries to calculate the probability of an outcome of a class given multiple evidences. It comes from the Bayes theorem and it is called naive as it tries to each of piece of evidence as independent. This approach is why this is called naive Bayes. However, I wonder why in the derivation of the mathematics behind Naive Bayesian Classificaiton, we take logs and odds. So my question is basically the following: Why odds and log odds transformations are meaningful ?
I would like to understand the first law of thermodynamics, but I have some problems with the basic concept. How to define exactly the internal energy? As I see it, given a system of particles, which the principle of work is in force for. Can it be considered 'per definitionem' the isolated thermodynamical system? If yes, the diatermic system can be defined as a system where the priciple of work isn't met. Therefore, if we define the internal energy as the sum of kinetic and potential energies of the particles, there is a term missing from the equation of the sum-work in diatermic case, called heat, which the first law postulates. How can heat be mathematically characterized?
It seems to me that in and of work equally well in sentences such as these: Habitat selection in birds is frequently studied. Habitat selection of birds is frequently studied. Variation is a key concept in statistics. Variation is a key concept of statistics. The function of behaviour is an important theme in evolution. The function of behaviour is an important theme of evolution. Should either in or of be favoured in the above sentences?
Is there some way to produce these figures using TeX itself preferably using TikZ? If yes, then I would also like to add labels right next to the nodes rather than using a legend. This is a screenshot from a paper I am reading and I would prefer using TeX to create them than using some external tools. EDIT I read the answer here but I would like to add the 'crosses' on the line instead of a gray colored line pointing to where the cross must exist. Moreover, I don't know how to change the crosses to the different symbols given in the diagram drawn above.
I'm writing a book and need help finding a word to describe a boy who immediately jumps to do what he is told. This is the sentence it will be used in -> "Ulric bring me a glass of water," Yohann says, in a raucous tone, as he turns back to the window seeming to forget about the ________ boy who scrambles to follow his grandfathers request. I might need to rephrase the sentence...
I'm uploading a very simple tufte handout based paper to arxiv and I'm getting an error: ! LaTeX Error: Option clash for package hyperref. but I am not loading hyperref anywhere. I'm only loading amsmath, babel, graphicx, polski (the polish latex package), booktabs, untis and multicol packages. I'm not chaning any hyperref options explicitly. Is there a general problem with arxiv supporting the tufte class?
I don't know how to describe exactly my issue, but I'll make a try: I am writing a document on Lyx, and I am using the module "report". I have customised the page margins but when I write paragraphs, some sentences do not obey the margin and some words are not in the same line. Graphically: From a PDF that is created with Office there is a tool (a ruler I think) with which you can make the paragraphs in order to be all the words in the same line. For example: How can i fix this issue?
Is there a word that refers to an official interest group held in school where registration is totally optional but members once registered are expected to come? Official means the school keeps records and members who do not reach a certain attendance threshold would be kicked out. I was thinking of school club but that seems to suggest that attendance is totally optional since clubs have the notion of come-and-go-whenever-you-like. On the other hand, the word association or organization sound too business-like. Besides school club, is there a better word that has a closer meaning to official school interest group?
I have the following figure: As of now I create this in Word/Powerpoint and paste the screenshot in a LaTeX file. Is there a way to create this natively? Also, what would be the advantage of doing so? The tables are just place holders and actual table design/content may change. But I prefer if it could be editable and not fixed. I'm not sure I even know where to start or how to go about it. I've never needed to draw anything in LaTeX before.
By my current understanding of the two words, the sentence: The preciseness of this precision is very definite is grammatically correct. Correct me if I'm wrong, and if so; what is the distinction between the two words? OED definition of preciseness: Exactness, accuracy; definiteness; minuteness. OED definition of precision: a. An instance of exactness or preciseness; a particular, nicety, minute detail, esp. of language. b. The fact, condition, or quality of being precise; exactness, accuracy. Also, what is the word for the situation in which this can occur? (I want to say it's the opposite of an oxymoron?)
I did the best I could. The sentence above can be rephrased: I did the best that I could. In these two examples (that) I could is a relative clause. However, I am not sure whether it is modifying best or the best or an ellipted element. What exactly is this clause modifying? Secondly, what type of phrase is the best here and what type of word is best?
Humour me for a minute here and let's imagine that all interesting and plausible supersymmetry models have been "cornered" out by the experimental data; what sort of alternatives are there for having quantum field theories with Poincare symmetry that are allowed to have nontrivial internal symmetries? i.e: that the Coleman-Mandula theorem does not apply? What other assumptions of the theorem can be relaxed or dropped, and still leave us with workable QFT? Are we forced to drop full Lorentz-Poincare symmetry or will the theorem still apply with slight violations of that symmetry?
How does one go about creating a TiKz library (is it even possible)? Is this a formidable task for a beginner? As a chemical engineer, I would very much like to have a library to create a process flow diagram, like the one below, in which you place nodes with certain shapes and connect them based on specific ports. Update: I actually found out that there are a couple of libraries for this purpose: chemplants PIDcircutTikZ
We observe in static electricity experiments that a comb rubbed on dry hair lifts tiny pieces of paper.This is due to the attraction force exerted by the charge collecting on the surface of the comb on the opposite charges collecting on the hair.This is a very small amount of force.But our body is always exerting gravitational force on all objects around it.Still it cannot draw such tiny pieces of papers.Why?
Non-unital completely positive (CP) maps take a maximally mixed quantum state (aka a normalized identity matrix aka an infinite temperature state) and map it to something else. This necessarily decreases its von Neumann entropy and, depending on how you define it, reduces its temperature. Can a stronger connection be made between thermodynamics and CP maps? To what extent do non-unital CP maps reliably cool states that aren't infinite temperature?
Layperson here. In a theoretical big crunch with space contracting faster than the speed of light, would information be travelling faster than speed of light? Because the points A and B themselves would be moving towards each other FTL. Maybe this is obvious or I have made a wrong assumption. Either way, please answer. Also, forgive if this has already been asked. I did search and couldn't find such a question.
Precision is usually understood as the number of significant figures in some experiment. Accuracy is the difference between the best measurement and the real value. How are precision and accuracy determined from a given experiment? Or equivalently, how are systematical errors and statistical errors calculated. Statistical errors are usually treated approaching "the normal distribution". But I am not sure how systematics are determined...Perhaps making some "pattern" measurements?
The Centroid point (at intersection of medians) divides a planar triangle into three equal-area smaller triangles. In case of spherical triangle, the three geodesics joining the vertex to the midpoint of the opposite side of spherical triangle intersect at a (Centroid-like) common point. But, when geodesic is constructed to join this Centroid-like point to the three vertices, the resultant smaller spherical triangles do not have equal area! A different geometrical method or a formula for implementing the exact division of spherical triangle into three equal-area spherical triangles could not be found in literature.
My question is very simple. I just would like to know what do they mean by: "I believe you're up" I've heard this expression in a movie and here is the script: I already met your dad. He loves me. Love is very strong word. Well, he at least likes me, right? We're busy tomorrow night. Okay, and we're back. Amy, I believe you're up. Oh, oh. Okay, I got this.
Our company uses project management software called Jira. In Jira you can mark one issue so that it 'escalades' another, or 'is escaladed' by another. I think that is something like 'cause', but you can set 'cause' or 'is caused', so they are different. And I find the meme 'that escalated quickly', and looks like it has a similar meaning to escalade. Can anyone tell me what escalade means in 'one issue escalades another'? Can I use escalate instead?
Some concepts are just too difficult to be fully understood. Take for example the multivariate causes of the recent recession: who among us can honestly say that he or she grasps the situation completely? With respect to topics like this, although it is not possible to thoroughly grasp the concept, attempts can be made to elucidate--at least partially--the more mysterious parts. Accordingly, is there a phrase that means, "To make less mysterious, but not explain completely because the concept is too difficult"?
The hotter something is glowing the more white/blue it appears. A dying medium sized star expands, cools and becomes a red giant for a while, but eventually it is going to gravitationally collapse (once enough Iron (Fe) is accumulated in the core). Then it blows the outer layers away and what is left collapses into a white dwarf. What makes the dwarf shine? and why is it white? Does the luminosity decreases as the object cools down, or is there some other reaction that keeps it glowing for a long time? Can a white dwarf turn brown or black never to be seen again? Do all white dwarfs turn into Neutron stars eventually?
I recently heard about the possibility of the creation of a "baby" universe or "pocket" universe from our space time,the theory says that concentrating enough mass into a tiny volume of space (like in black holes) a pocket of false vacuum would form e perhaps it'll continue to expand following it's own inflation period and go on forever completly disconnected from our space time without influencing it any way. Now my question is : supposing that we live in a metastable vacuum we know that true vacuum bubble could form via quantum tunnelling and begin to expand into our space time where these false vacuum bubble (or pocket/baby universe) are supposed to go and expand ?
Possible Duplicates: Salutation in an Email How do you greet multiple recipients in an e-mail? How do I use the initial words while writing an e-mail, in particular, to my superiors? Suppose somebody is writing a letter to the HR representative of a company, requesting a letter, approval, information, etc. Should the salutation be written like: Hi or: Dear or her/his name: Dear Jenny Are any of these proper way? Or, should I leave it blank and start with the crux of the matter right away? Does it matter whether I know the person or not, or if the person is not my superior but is a colleague or junior?
According to the work of J. Scott Carter you can draw pictures of knotted surfaces in four-space in several different ways. I know the man is a real artist in this, but did anybody come across some software that does this for you ? See for example: http://www.jscottcarter.com/) I guess you can figure out a parametric equation for a knotted sphere, and pay a trip to Mathematica-land, but I haven't done this. This is probably a more specialized version of Topology software)
I'm looking for a positive word or phrase - though ideally, a single word - that suggests that old dubious beliefs are being re-examined and questioned. "Self-doubt", has a negative connotation and I would like this to indicate a sort of personal growth. For example, it could describe someone who used to be paranoid and believe that everyone was conspiring against them learning to become more trusting.
In this problem are only truth tellers and liars. When meeting two people, A and B, you ask A: "Is any of you a truth teller?", to which A replies: "If B is a liars, then i'm a liar" What are A and B? What I got so far is: If A is telling the truth, then the statement must be true when B is telling the truth, and false when B is lying. If A is lying, then the statement must be true when B is telling the truth, and false when he is lying. I can't seem to find a way to logically formulate this, and I'm thinking this might be because I'm missing something. Have I got it right?
A colleague once disparaged his own research to me by saying that it didn't involve any sort of cohomology. It does, in fact, seem like homological ideas appear across disciplines...and are considered to be mathematically "sexy". I wonder what the deep reason for this is? (The answer "because these ideas prove many things" seems cheap, or ad-hoc here.) Where can I find a "bird's eye" modern view of general homology/cohomology?
I'm writing a thesis and would like to have the pages on which a new chapter start look fancier than they currently do. I like the example on this page: how can I create a chapter heading like this? However, since the abstract is defined in the preamble, it appears the same in each chapter. Obviously, different chapters need different abstracts and I don't know how to correct this? Secondly, for some reason, the contents of this preamble are changing the font style of the rest of my document and I'd like the bulk of what I'm writing (outside of chapter title and abstract) to stay in the standard font that LaTeX uses. Thanks for any help.
I asked a similar question on SciComp, but it is a little out of the domain, so I thought I'd give it a try here as well. Give n points, I would like to place them in a periodic box (periodic such that the distance between two points "wraps around" to the other side) so that the minimum distance between any two points is as large as it can possibly be. How do I do this? I imagine analytically this could be quite difficult, but is there at least a numerical procedure?
