Polynomials evaluated at integers by John D. Cook

Polynomials evaluated at integers by  John D.  Cook     Let p(x) = a0 + a1x + a2x2 + … + anxn and suppose at least one of the coefficients ai is irrational for some i ≥ 1. Then a theorem by Weyl says that the fractional parts of p(n) are equidistributed as n varies over the integers. That is, the proportion of values that land in some interval is equal to the length of that interval. Clearly it’s necessary that one of the coefficients be irrational. What may be surprising is that it is sufficient. If the coefficients are all rational with common denominator N, then the sequence would only contain multiples of 1/N. The interval [1/3N, 2/3N], for example, would never get a sample. If a0 were irrational but the rest of the coefficients were rational, we’d have the same situation, simply shifted by a0. This is a theorem about what happens in the limit, but we can look at what happens for some large but finite set of terms. And we can use a χ2 test to see how evenly our sequence is compared to what one would expect from a random sequence. Mostrar detalle

¿Qué es la malaria?

¿Qué es la malaria?     La Malaria es una enfermedad parasitaria que involucra fiebres altas, escalofríos, síntomas seudogripales y anemia. Causas La malaria o paludismo es causada por un parásito que se transmite a los humanos a través de la picadura de mosquitos anofeles infectados. Después de la infección, los parásitos (llamados esporozoítos) viajan a través del torrente sanguíneo hasta el hígado, donde maduran y producen otra forma, llamada merozoítos. Los parásitos ingresan en el torrente sanguíneo e infectan a los glóbulos rojos. Los parásitos se multiplican dentro de los glóbulos rojos, los cuales se rompen al cabo de 48 a 72 horas, infectando más glóbulos rojos. Los primeros síntomas se presentan por lo general de 10 días a 4 semanas después de la infección, aunque pueden aparecer incluso a los 8 días o hasta 1 año después de esta. Los síntomas ocurren en ciclos de 48 a 72 horas. La mayoría de los síntomas son causados por: La liberación de merozoítos en el torrente sanguíneo Anemia resultante de la destrucción de glóbulos rojos Grandes cantidades de hemoglobina libre liberada en la circulación luego de la ruptura de los glóbulos rojos Mostrar detalle

Pyton

Python vs R: 4 Implementations of Same Machine Learning Technique

Python vs R: 4 Implementations of Same Machine Learning Technique     Actually, this is about two R versions (standard and improved), a Python version, and a Perl version of a new machine learning technique recently published here. We asked for help to translate the original Perl script to Python and R, and finally decided to work with Naveenkumar Ramaraju, who is currently pursuing a master's in Data Science at Indiana University. So the Python and R versions are from him. We believe that this code comparison and translation will be very valuable to anyone learning Python or R with the purpose of applying it to data science and machine learning. Mostrar detalle

Quantum

Quantum computing might have just gone to a whole new level

Quantum computing might have just gone to a whole new level     In brief A pair of researchers from the University of Tokyo have developed what they're calling the "ultimate" quantum computing method. Unlike today's systems, which can currently only handle dozens of qubits, the pair believes their model will be able to process more than a million. Around and around Today’s working quantum computers are already more powerful than their traditional computing counterparts, but a pair of researchers from the University of Tokyo think they’ve found a way to make these remarkable machines even more powerful. In a research paper published in Physical Review Letters, Akira Furusawa and Shuntaro Takeda detail their novel approach to quantum computing that should allow the machines to perform a far greater number of computations than other quantum computers. At the center of their new method is a basic optical quantum computing system — a quantum computer that uses photons (light particles) as quantum bits(qubits) — that Furusawa devised in 2013.

Battery

Ultrafast Charging High Capacity Asphalt–Lithium Metal Batteries

Ultrafast Charging High Capacity Asphalt–Lithium Metal Batteries     Li metal has been considered an outstanding candidate for anode materials in Li-ion batteries (LIBs) due to its exceedingly high specific capacity and extremely low electrochemical potential, but addressing the problem of Li dendrite formation has remained a challenge for its practical rechargeable applications. In this work, we used a porous carbon material made from asphalt (Asp), specifically untreated gilsonite, as an inexpensive host material for Li plating. The ultrahigh surface area of >3000 m2/g (by BET, N2) of the porous carbon ensures that Li was deposited on the surface of the Asp particles, as determined by scanning electron microscopy, to form Asp–Li. Graphene nanoribbons (GNRs) were added to enhance the conductivity of the host material at high current densities, to produce Asp–GNR–Li. Asp–GNR–Li has demonstrated remarkable rate performance from 5 A/gLi (1.3C) to 40 A/gLi (10.4C) with Coulombic efficiencies >96%. Stable cycling was achieved for more than 500 cycles at 5 A/gLi, and the areal capacity reached up to 9.4 mAh/cm2 at a highest discharging/charging rate of 20 mA/cm2 that was 10× faster than that of typical LIBs, suggesting use in ultrafast charging systems. Full batteries were also built combining the Asp–GNR–Li anodes with a sulfurized carbon cathode that possessed both high power density (1322 W/kg) and high energy density (943 Wh/kg).

Artificail-Intelligence

What is Machine Learning?

What is Machine Learning?     Machine learning is a method of data analysis that automates analytical model building. It is a branch of artificial intelligence based on the idea that machines should be able to learn and adapt through experience. Evolution of machine learning Because of new computing technologies, machine learning today is not like machine learning of the past. It was born from pattern recognition and the theory that computers can learn without being programmed to perform specific tasks; researchers interested in artificial intelligence wanted to see if computers could learn from data. The iterative aspect of machine learning is important because as models are exposed to new data, they are able to independently adapt. They learn from previous computations to produce reliable, repeatable decisions and results. It’s a science that’s not new – but one that has gained fresh momentum. While many machine learning algorithms have been around for a long time, the ability to automatically apply complex mathematical calculations to big data – over and over, faster and faster – is a recent development. Here are a few widely publicized examples of machine learning applications you may be familiar with: The heavily hyped, self-driving Google car? The essence of machine learning. Online recommendation offers such as those from Amazon and Netflix? Machine learning applications for everyday life. Knowing what customers are saying about you on Twitter? Machine learning combined with linguistic rule creation. Fraud detection? One of the more obvious, important uses in our world today. Mostrar detalle

Phones

Preserving Mobile Phone History as ten years ago

Preserving Mobile Phone History as ten years ago     his article first appeared in the Telecommunications Heritage Journal, Issue Number 61, Winter 2007 and is reproduced with the permission of the Telecommunications Heritage Group It is a fact that there are more mobile phones in the United Kingdom than people and this has been true for a couple of years. Added to this, the latest figures produced by the International Telecommunications Union confirm that at the end of 2006, there were almost 2.7 billion mobile subscribers globally or alternatively, 41% of the world’s population now own a mobile phone. Indeed having just read this figure you can be fairly sure that it has already increased. No other communications technology has achieved this level of penetration and certainly, no other technology has made its impact so rapidly. The usage of mobiles is equally staggering. On New Years Day 2007, a new record was set for the number of SMS text messages sent over the UK’s mobile networks. How many? An amazing 214 million; in just one day! That’s the equivalent of approximately 9 million per hour or just over 3 for every man, woman and child living in the UK. So why therefore am I writing an article about the history of a technology that is in widespread everyday use, is still evolving and is regarded as new by those that use it? Well, that is precisely the point. The mobile phone industry is moving forward so quickly and is so obsessed with tomorrow’s device that the heritage is being forgotten. There are more websites devoted to the good old GPO 700 series rotary dial telephone than to the history of mobile phones. Even major manufacturers like Nokia and Motorola seem to be ignoring the rich legacy and heritage that their products represent. Mostrar detalle
