Disorder Definition and 77 Threads

I want to write a short-line code which can generate some configurations of a rough interface with small alloy disorder. The problem is stated in the following: two neighboring interface layer I & II Layer I is mainly consisted of atom A, but with substitutional disorder, i.e. some sites are...

Hi all, I'm wanting to write a small program simulating a 1D lattice with some motion. I have the equation: m_{n}\frac{d^{2}u_{n}}{dt^{2}}= k_{n,n+1}(u_{n+1}-u_{n})+k_{n-1,n}(u_{n-1}-u_{n}) Then using a simple trial plane wave (u_{n}=Ae^{-i\omega t}). It boils down to: - \omega^{2}...

When we talk about Entropy we look at how the disorder in a system is measured. Now if we see the whole universe as a system, we can say that the universe tends to constantly go towards more disorder since it is expanding. My question is: If the universe which we live in and governs everything...

I watched this movie where a lady suffering from dissociative personality disorder, hears a story about a dancer whose ghost is said to haunt a palace, and the lady starts behaving like the dancer sporadically. In the movie they show that she starts to speak in a language she did not know...

Anthropixia is an intellectual illness to the extent that let's physicists off the hook---gives them an excuse, that is, to shirk their job as explainers. Discouraged theorists are particularly subject to this disorder. Those at the end of their productive years, who have failed to find the ToE...

Hello. I am a thirteen year old recently diagnosed with type one bipolar disorder with psychotic features. Thing is, my meds don't always work. I can't deal with the voices when I am sick. My only coping strategy is my iPod. Are there any ways to make them go away? Thank you *so* much.

For example, in tight binding model, the site energy is random I want to have 100 disorder realizations, then I have the following two questions: 1. Do different realization needs different seed in the random number generation subroutine? 2. When all realizations are completed, the...

I think many children suffer from this disease and powerful pills should be given to them.

I have read several articles about this lately. The bees apparently fly away and never come back. Is this something new or just a periodic natural occurrence? I really couldn't find anything on Google that gave an adequate answer. I know there was a mite infestation that killed millions...

Consider a drug user who habitually takes MDMA ecstasy once per week. This user experiences an acute euphoria for hours following the initial dosage. This euphoria can be attributed to, among other factors, the release of the neurotransmitters seratonin and dopamine into the bloodstream. Once...

Personality disorder test...:rolleyes:

i got this question in my chem review worksheet State if the following increases or decreases the disorder of a system? 1) sublimation of dry ice 2) freezing of water 3) increasing pressure over Nitrogen gas that is above water i put 1) increase 2) decrease 3) increase

Hello, I was wondering what exactly Down's Sydrome is a disorder of? I mean is it a disorder in the expression of ones thoughts into movements, such as speech, or is it a disorder that directly effects the thought process? -Scott

Does anyone have insights or a perspective on the possible biological roots of PA behavior (or disorder)? I am not a psychologist, psychiatrist, or biologist, but when I think of the evolution of the species it kind of seems obvious that the mammals lived a hard life under the dinosaurs' feet...

When two individuals have a difference of opinion, especially about politics or religion, then they get furious, aggressive and become your worst enemy. On the other hand, if you know someone or even a stranger that shares similar view then you, then automatically you get the feeling he is...

I was wondering if anyone has heard of a disorder where someone has to be the smartest guy in the room. This person gets anxious when you present them with an idea they have not fully thought through. They enjoy the company of those they know to be inferrior. Dislike creative ideas from those...

I'm not sure if this is the appropriate place to post this, but I noticed someone else posted a topic on dyslexia in here. I'm kind of a newb here and mostly lurk the relativity, and brain teasers forums, so I apologize if this is the wrong place. Anyways, I've been having problems with panic...

How do you respond to climactic clues year-round? I find some subtle yet profound emotional memories involved with seasonal situations, like the depression I now am beginning to reexperience. For instance, have you ever tried to recall the elements a half-year ago to appreciate what the...

In physics entropy is typically referred to as a measure of disorder in a physical system however I have seen it referred to as a measure of statistical uncertainty for a set of data. I also recall the function defined the statistical uncertainty took the form of an integral and is used in...

Let's say you have a hypothetical species of animal and on average, these animals reach sexual maturity at age 10, will breed from age 10 to age 20, and die at age 50. Let's also say that there is an individual who is homozygous for a unique genetic disorder that will cause him to die at age...

Hi All - OK, I understand that entropy increases over time, thermodynamic arrow , etc. But I don't fully grasp the concept in simple terms. I know that there are apparently many more states of disorder for a particular system than order (like Hawking says, puzzle pieces in a box). So if...

Ok, so we have a parameter X say. Now, we have a mean x-bar, that is the mean, X being random. Now, by basic statistics, the variation , that is V(X) = E (X)^2 - (x-bar)^2 is the disorder. Is it so? The interpretation of the disorder by me is correct or not? I have nice property of...

I have visited your forums with interest and have posted this, in the hope, that someone may be able to shed some light on the situation I find myself within. My partner, wakes at night (at least 2, sometimes 3 times), proceeds to pour out his heart with speech patterns that are not his...

How do we know if a system is ordered or disordered? What may appear as order could be disorder. On the other hand what can appear to be disorder may be order at a level that we cannot preceive as order. I know David Bohm talks about this in his theory of implicate and explicate orders. Is it...

I haven't read anything particularly recent on this topic, so I have some questions: 1) Does it actually exist, prior to therapy? This may seem like a really stupid question, but there have been papers on the topic that indicated it could be conjured up by the patient's subconscious due...

It is interesting to note how a metabolic disorder can remain unnoticed in a child until some crisis occurs. I had a case study yesterday (taking from an episode of ER) where a young child (maybe 4) gets rushed to the hospital, comatoze, seizing for 20 minutes. The child was fine that...

Entropy (disorder), S, is defined by S=k(ln[0]), where k is Boltzmann's constant, and [0] is the number of states in the closed system. Anentropy (order), A, arises from the entropy of the system as A=k(ln(ln[0]))=k(ln(S/k)) and represents a subsystem of continuous, maximally unchanged states...
