Over the past two centuries human life expectancy has increased by nearly 50 years. Genetic factors account for about one-third of the variation in life expectancy so that most of the interindividual variation in lifespan is explained by stochastic and environmental factors, including diet. In some model organisms, dietary (energy) restriction is a potent, and highly reproducible, means of incr...

Roads are land transportation facilities that very important in facilitating economic relations activities, both between one city and another. Good road conditions will facilitate the movement of people relationships other social activities. Meanwhile, if there is damage, it not only hinder but accidents can occur. Many factors cause including weather, weather on surface when rains, scorching h...

Let p be a prime congruent to 1 modulo 4, and let t, u be rational integers such that (t + u √ p )/2 is the fundamental unit of the real quadratic field Q(√p ). The Ankeny-Artin-Chowla conjecture (AAC conjecture) asserts that p will not divide u. This is equivalent to the assertion that p will not divide B(p−1)/2, where Bn denotes the nth Bernoulli number. Although first published in 1952, this...

The Cancer Registry of Norway organises a population-based breast cancer screening program, where 250 000 women participate each year. interpretation the mammograms is manual process, but deep neural networks are showing potential in mammographic screening. Most methods focus on trained from pixel-level annotations, these require expertise and time-consuming to produce. Through screenings, imag...

Introduction: All-optical wavelength converters (AOWC) are envisioned to be part of future high-speed networks. In particular, they might replace optical-to-electrical-to-optical (OEO) wavelength translator units in optical crossconnects [1]. However, to be practical, AOWCs must be able to convert signals that have been degraded during transmission over reasonable distances. Tolerance to timing...
