This work proposes a dynamic and fair spectrum management strategy to be adopted by a service provider (SP). Here, we consider a scenario where multiple access networks (ANs) of different (not necessarily competing) technologies are owned by a single SP. We envisage that an SP employs an entity, called local spectrum controller (LSC), which manages a common pool of spectrum and is responsible f...

Lexico-semantic collocations (LSCs) are a prominent type of multiword expressions. Over the last decade, the automatic compilation of LSCs from text corpora has been addressed in a significant number of works. However, very often, the output of an LSC-extraction program is a plain list of LSCs. Being useful as raw material for dictionary construction, plain lists of LSCs are of a rather limited...

Improvement of solid oxide fuel cells strongly relies on the development of cathode materials with high catalytic activity for the oxygen reduction reaction. Excellent activity was found for perovskite-type oxides such as La1-xSrxCoO3-δ (LSC), but performance degradation, probably caused by surface composition changes, hinders exploitation of the full potential of LSC. This study reveals that t...

INTRODUCTION AND AIMS We aim to compare clinical and surgical outcomes between minilaparoscopic sacrocolpopexy (MLSC) and conventional laparoscopic sacrocolpopexy (LSC). As far as we know, no comparative study exists between these two minimal invasive procedures to correct vaginal prolapse. DESIGN AND SETTING An observational and comparative study with 20 individuals submitted to vaginal vaul...

Cancer stem cells represent a novel therapeutic target. The major challenge in targeting leukemic stem cells (LSC) is finding therapies that largely spare normal hematopoietic stem cells (HSC) while eradicating quiescent LSCs. We present a mathematical model to predict how selective a therapy must be to ensure that enough HSCs survive when LSCs have been eradicated. Stem cell population size is...

In this work, a Monte Carlo ray-tracing model for the simulation and optimization of fiber Luminescent Solar Concentrator (LSC) based on stacked layers arrays is developed validated. The LSC efficiency improvements are compared against conventional planar LSC. We new to analyze performance different configurations bulk-doped fibers constituted by doped coating passive core. These analyzed also ...

The thermal neutron background at Laboratorio Subterráneo de Canfranc (LSC) has been determined using several 3He proportional counter detectors. Bare and Cd shielded counters were used in a series of long measurements. Pulse shape discrimination techniques applied to discriminate between gamma signals as well other intrinsic contributions. Montecarlo simulations allowed us estimate the sensiti...

Leaf specific conductivity (LSC; the ratio of stem conductivity (K(P)) to leaf area (A(L))), a measure of the hydraulic capacity of the stem to supply leaves with water, varies with soil water content. Empirical evidence for LSC responses to drought is ambiguous, because previously published results were subject to many confounding factors. We tested how LSC of similar-sized trees of the same p...

In the plant pathogen Pseudomonas syringae pv. glycinea PG4180 and other bacterial species, synthesis of the exopolysaccharide levan is catalyzed by the extracellular enzyme levansucrase. The results of Southern blotting and PCR analysis indicated the presence of three levansucrase-encoding genes in strain PG4180: lscA, lscB, and lscC. In this study, lscB and lscC were cloned from a genomic lib...

Complex systems are of interest to the scientific community due to their ubiquity and diversity in daily life. Popularity notwithstanding, the analysis of complex systems remains a difficult task, due to the problems in capturing high-volume data. Massively Multiplayer Online Games (MMOGs) have recently emerged as a tractable way to analyze complex system interactions, because these virtual env...
