A fundamental issue in studies of protein structure and function is how to identify the conserved common core in multiple protein structures. The existing algorithms work well for proteins family such as those in HOMSTRAD but are not satisfactory for general multiple structure alignment problems, especially in some challenging cases, such as the occurrence of circular permutations. In this pape...

Nurse staffing and scheduling is a major health human resource issue currently facing healthcare organizations. To increase the capacity of healthcare organizations to address a variety of issues related to nurse staffing and scheduling, a mult-isite collaborative project was undertaken. The primary focus of this project was

Within the neurosciences it is natural to observe variability across time in dynamics of an underlying brain process. Wavelets are essential analysing signals because, even within a single trial, exhibit nonstationary behaviour. However, neurological generated experiment may also potentially evolution trials (replicates), for identical stimuli. As neurologists consider localised spectra be most...

The notion of perfect correlations between arbitrary observables, or more generally arbitrary POVMs, is introduced in the standard formulation of quantum mechanics, and characterized by several well-established statistical conditions. The transitivity of perfect correlations is proved to generally hold, and applied to a simple articulation for the failure of Hardy’s nonlocality proof for maxima...

In the course of his construction [N] of a counterexample to Hilbert's 14th problem, Nagata was led to formulate a conjectural lower bound on the degree of a plane curve having assigned multiplicities at a generic collection of points. To state the conjecture precisely, recall first that the multiplicity mult P (C) of an arbitrary plane curve C (=pos

În lucrare se exemplifică cum în silvicultura științifică europeană, din necesități teoretice și practice, s-au descoperit folosit, chiar de la început, noțiuni ecologice, uneori cu mult înainte ca acestea să fi fost definite utilizate autecologie (relații între organisme mediul lor abiotic), dem-ecologie (caracteristici cantitative ale populațiilor arbori a altor populații forestiere), sinecol...

Real-coded genet ic algorit hms (GAs) do not use any coding of the problem variab les, instead they work dir ectly with the variab les . The main difference in the implementation of real-coded GAs and binary-coded GAs is in their recombination op erators. Alt ho ugh a number of real-cod ed crossover implementations were suggested, most of them were developed wit h intuition and wit hout much an...
