Meet Pseudomonas syringae, a bacterium that causes disease in plants and helps make snow machines work. It all has to do with ice nucleation — the process that forms ice crystals in the atmosphere and, thus, snow. You probably know that raindrops and snowflakes form around something. There's always a central nucleus that serves as the backbone of the water molecule structure. Usually, when people talk about this process, they use soot or some other kind of particulate matter as the example of what a nucleus can be. But bacteria can also become the nucleus of a snowflake.

Un article de Wikipédia, l'encyclopédie libre. Le poly(p-phénylènetéréphtalamide) (PPD-T) est un polymère thermoplastique constitué de noyaux aromatiques séparés par des groupes amide. Il appartient à la famille des fibres d'aramides. Le PPD-T est commercialisé sous le nom déposé de Kevlar. Ce dernier, comme les autres fibres textiles, ne fait pas partie des matières plastiques.

Music information retrieval Music information retrieval (MIR) is the interdisciplinary science of retrieving information from music. MIR is a small but growing field of research with many real-world applications. Those involved in MIR may have a background in musicology, psychology, academic music study, signal processing, machine learning or some combination of these. Applications of MIR[edit] MIR is being used by businesses and academics to categorize, manipulate and even create music. Recommender systems[edit] Music information retrieval
In sound processing, the mel-frequency cepstrum (MFC) is a representation of the short-term power spectrum of a sound, based on a linear cosine transform of a log power spectrum on a nonlinear mel scale of frequency. Mel-frequency cepstral coefficients (MFCCs) are coefficients that collectively make up an MFC. They are derived from a type of cepstral representation of the audio clip (a nonlinear "spectrum-of-a-spectrum"). Mel-frequency cepstrum Mel-frequency cepstrum

Un article de Wikipédia, l'encyclopédie libre. Ne doit pas être confondu avec graphème. Le graphène est un cristal bidimensionnel (monoplan) de carbone dont l'empilement constitue le graphite. Il a été isolé en 2004 par Andre Geim, du département de physique de l'université de Manchester, qui a reçu pour cette découverte le prix Nobel de physique en 2010 avec Konstantin Novoselov. Il peut être produit de deux manières : par extraction mécanique du graphite (graphène exfolié) dont la technique a été mise au point en 2004, ou par chauffage d'un cristal de carbure de silicium, qui permet la libération des atomes de silicium (graphène epitaxié).

10 Reasons an Artificial Intelligence Wouldn't Turn Evil Awesome post.. I'm now more afraid of having my limbs chopped off, despite your skilled arguments against such a fate. Some general thoughts on the matter - I see no reason why an AI, or any set of AIs, wouldn't be susceptible to some form of irrationality, or even emotions of a very alien kind. In particular, this seems more plausible if much of the AI is assembled via evolutionary processes. Imagine an AI learning how to interact with humans via Internet discussions/comments. 10 Reasons an Artificial Intelligence Wouldn't Turn Evil

Approximate string matching Overview[edit] The closeness of a match is measured in terms of the number of primitive operations necessary to convert the string into an exact match. This number is called the edit distance between the string and the pattern. Approximate string matching

​Extract Money From People Using the Ambiguity Effect Wait, do I understand correctly that there is a varying number of black vs white marbles? "There are thirty red marbles for sure, but there's a mix of black and white marbles, and I can't be sure how many of each is in there." If that's the case, then the red marbles would always have a 1/3 chance of winning, but depending on the distribution of black vs white marbles, one of those colors may have a vastly reduced chance of winning, right? Overall, the three colors would add up to 3/3 chance of winning, but they don't all get there at the 1/3. Of course, I'm terrible at this kind of thing so please tell me where I've misunderstood.
Researchers using data obtained by the orbiting Fermi Telescope may have found the first clear, direct evidence of dark matter in our own galaxy. The signal comes in the form of an excess of gamma rays coming from an area surrounding the galactic core, and it appears to be exactly what we'd expect from a weakly interacting massive particle, or WIMP. Perhaps as significantly, however, there are no known astronomical features that can produce a signal like this. Fermi telescope detects signal that could be annihilating dark matter

Gambler's fallacy The gambler's fallacy, also known as the Monte Carlo fallacy or the fallacy of the maturity of chances, is the mistaken belief that if something happens more frequently than normal during some period, then it will happen less frequently in the future; likewise, if something happens less frequently than normal during some period, then it will happen more frequently in the future (presumably as a means of balancing nature). In situations where what is being observed is truly random (i.e. independent trials of a random process), this belief, though appealing to the human mind, is false. This fallacy can arise in many practical situations although it is most strongly associated with gambling where such mistakes are common among players.

Forensic Scientists Build Crude 3D Mugshots From DNA DNA evidence was first used to help solve crimes in 1986, but it didn’t hit the main stage of the public’s attention until it was used in OJ Simpson’s murder trial in 1994. This relied on DNA fingerprinting, which is now commonly used in trials. One unfortunate flaw is that it requires a suspect - without a person to match it to, DNA evidence doesn’t mean a whole lot. The field of genetics has come a long way over the last few decades, so now could we actually use DNA found at a crime scene to locate the suspect, even without any leads? A new study led by Mark Shriver of Penn State has shown that rough 3D mugshots can be built from genetic samples by using a mere 24 genetic variants. The results have been published in the open access journal PLOS Genetics.
