The Steiner tree problem (STP) is one of the most popular combinatorial optimization problems with various practical applications. In this paper, we propose a Breakout Local Search (BLS) algorithm for an important generalization of the STP: the Steiner tree problem with revenue, budget and hop constraints (STPRBH), which consists of determining a subtree of a given undirected graph which maximi...

Lumazine synthase from Brucella spp. (BLS) is a highly immunogenic decameric protein which can accommodate foreign polypeptides or protein domains fused to its N-termini, markedly increasing their immunogenicity. The inner core domain (VP8d) of VP8 spike protein from bovine rotavirus is responsible for viral adhesion to sialic acid residues and infection. It also displays neutralizing epitopes,...

An out-of-hospital cardiac arrest (OHCA) is one of the leading causes death in world. The survival rate can be influenced by chain survival. school institution that has opportunity to promote education citizens basic life support (BLS), increasing number trained bystanders. This study aimed identify theoretical and practical knowledge self-reported skills BLS, order characterize motivation inte...

Abstract Railway point machine (RPM) condition monitoring has attracted engineers’ attention for safe train operation and accident prevention. To realize the fast accurate fault diagnosis of RPMs, this paper proposes a method based on entropy measurement broad learning system (BLS). Firstly, modified multi-scale symbolic dynamic (MMSDE) module extracts characteristics from collected acoustic si...

Laminin trimers composed of alpha, beta, and gamma chains are major components of basal laminae (BLs) throughout the body. To date, three alpha chains (alpha1-3) have been shown to assemble into at least seven heterotrimers (called laminins 1-7). Genes encoding two additional alpha chains (alpha4 and alpha5) have been cloned, but little is known about their expression, and their protein product...

BACKGROUND Basic life support (BLS) guidelines focus on chest compressions with a minimal no-flow fraction (NFF), early defibrillation, and a short perishock pause. By using an automated external defibrillator (AED) lay persons are guided through the process of attaching electrodes and initiating defibrillation. It is unclear, however, to what extent the voice instructions given by the AED migh...

BACKGROUND Implementation of new guidelines into clinical practice is often incomplete. Direct mail is a simple way of providing information to physicians and may improve implementation of new guidelines on basic life support (BLS). The aim of this study was to describe knowledge of the most recent European Resuscitation Council (ERC) Guidelines for BLS among general practitioners (GPs) and inv...

BACKGROUND Prehospital care is classified into ALS- (advanced life support) and BLS- (basic life support) levels according to the methods used. ALS-level prehospital care uses invasive methods, such as intravenous fluids, medications and intubation. However, the effectiveness of ALS care compared to BLS has been questionable. AIM The aim of this systematic review is to compare the effectivene...

BACKGROUND First responders are recommended as a supplement to the Emergency Medical Services (EMS) in order to achieve early defibrillation. Practical and organisational aspects are essential when trying to implement new parts in the "Chain of Survival"; areas to address include minimizing dispatch time, ensuring efficient and quick communication, and choosing areas with appropriate driving di...

Objectives To describe learning outcomes of undergraduate nursing students following an online basic life support course (BLS). Methods An online BLS course was developed and administered to 94 nursing students. Pre- and post-tests were used to assess theoretical learning. Checklist simulations and feedback devices were used to assess the cardiopulmonary resuscitation (CPR) skills of the 62 s...
