Nutrition and Cardiovascular Disease: Finding the Perfect Recipe for Cardiovascular Health
The increasing burden of cardiovascular disease (CVD) despite the progress in management entails the need of more effective preventive and curative strategies. As dietary-associated risk is the most important behavioral factor influencing global health, it appears the best target in the challenge against CVD. Although for many years, since the formulation of the cholesterol hypothesis, a nutrie...
متن کاملThe quest of finding the perfect spermatozoon
tau.amegroups.com © Translational Andrology and Urology. All rights reserved. Infertility is a health problem that touches around 15% of couples worldwide and male infertility is the sole cause in half of these cases (1,2). Since the development of assisted reproductive techniques (ART) particularly intracytoplasmic sperm injection (ICSI), it has been a challenge to select the very best spermat...
متن کاملFinding Almost-Perfect Graph Bisections
We give a polynomial time algorithm that given a graph which admits a bisection cutting a fraction (1 − ε) of edges, finds a bisection cutting a (1 − g(ε)) fraction of edges where g(ε) → 0 as ε→ 0. One can take g(ε) = O( 3 √ ε log(1/ε)). Previously known algorithms for Max Bisection could only guarantee finding a bisection that cuts a fraction of edges bounded away from 1 (in fact less than 3/4...
متن کاملA recipe for finding good solutions to MINLPs
Finding good (or even just feasible) solutions for Mixed-Integer Nonlinear Programming problems independently of the specific problem structure is a very hard but practically important task, especially when the objective and/or the constraints are nonconvex. With this goal in mind, we present a general-purpose heuristic based on Variable Neighborhood Search, Local Branching, a local Nonlinear P...
متن کاملFinding Succinct Ordered Minimal Perfect Hash Functions
An ordered minimal perfect hash table is one in which no collisions occur among a prede ned set of keys, no space is unused and the data are placed in the table in order. A new method for creating ordered minimal perfect hash functions is presented. It creates hash functions with representation space requirements closer to the theoretical lower bound than previous methods. The method presented ...
