We discuss magnetoexcitons dispersion in single and coupled GaAs − (Ga,Al)As quantum wells using the Bethe-Salpeter (B-S) formalism. The B-S formalism in the case of quantum wells provides an equation for the exciton wave function which depends on two space variables plus the time variable, i.e. the B-S equation is 2 + 1-dimensional equation. We compare the results for magnetoexcitons dispersio...

The Lovász Local Lemma (LLL) is a powerful tool that is increasingly playing a valuable role in computer science. It has led to solutions for numerous problems in many different areas, reaching from problems in pure combinatorics to problems in routing, scheduling and approximation theory. However, since the original lemma is non-constructive, many of these solutions were first purely existenti...

BACKGROUND Residency programs use electronic portfolios (efolios) to organize data, track resident performance, and sometimes teach and assess lifelong learning (LLL) skills. Published studies on efolios in graduate medical education are mostly descriptions of implementation at individual institutions. METHODS An anonymous online survey was sent to 199 pediatric residency program directors ac...

BACKGROUND Lower limb lymphedema (LLL) is an important concern for patients with vulvar cancer. Studies of the incidence of vulvar cancer-related lymphedema and its risk factors have substantially increased in the new millennium. OBJECTIVES This article is a meta-analysis that aimed to systematically evaluate the incidence of LLL and its risk factors related to vulvar cancer. DATA SOURCES D...

Lattices in Computer Science Lecture 2 LLL Algorithm Lecturer: Oded Regev Scribe: Eyal Kaplan In this lecture1 we describe an approximation algorithm to the Shortest Vector Problem (SVP). This algorithm, developed in 1982 by A. K. Lenstra, H. W. Lenstra, Jr. and L. Lovasz, usually called the LLL algorithm, gives a ( 2 √ 3 ) n approximation ratio, where n is the dimension of the lattice. In many...

Abstract—Background: Diabetic sensorimotor polyneuropathy (DSP) is one of the most common microvascular complications of type 2 diabetes. Loss of sensation is thought to contribute to a lack of static and dynamic stability and increased risk of falling. Purpose: The purpose of this study was to compare the effects of low-level laser (LLL) and monochromatic near-infrared photo energy (MIRE) on p...

A canine model of unilobar papain-induced emphysema was used to examine the extent to which differences in alveolar pressures (PA) would develop between an emphysematous right lower lobe (RLL) and normal left lower lobe (LLL) during forced vital capacity (FVC) deflation. RLL and LLL PA (PARLL and PALLL, respectively) were measured by the alveolar capsule technique. During forced deflation, PA a...

Abstract Background Traditional right ventricular apical pacing can cause electrical–mechanical dyssynchrony. Therefore, physiological conduction system was considered and became the reason for developing His bundle (HBP). Recently, left branch area (LBBAP) has been implemented, which overcomes shortcomings of HBP. Most initial large LBBAP studies reported that achieved through a lumenless lead...
