An experimental investigation of the lee-side flow on sharp leading-edge delta wings at supersonic speeds has been conducted. Pressure data were obtained Mach numbers from 1.5 to 2.8, and three types flow-visualization (oil-flow, tuft, vapor-screen) 1.7 2.8 for wing sweep angles 52.5 deg 75 deg. From data, flows classified into seven distinct a chart was developed that defines mechanism as function conditions normal leading edge, specifically, angle attack number. experimentally by...
Managing healthcare demand and capacity is especially difficult in the context of COVID-19 pandemic, where limited intensive care resources can be overwhelmed by a large number cases requiring admission short space time. If patients are unable to access this specialist resource, then death likely outcome. In appreciating these 'capacity-dependent' deaths, paper reports on clinically-led development stochastic discrete event simulation model designed capture key dynamics admissions process...

The include sulfonic acid, phosphonic and sulfonimide units. different impart water retention, proton conduction, methanol resistance membranes. Special advantages are foreseen for uses in direct cells. © 2006 Wiley Periodicals, Inc. J Polym Sci Part B: Phys 44: 2358–2368,
The communities in fishing villages the Great Lakes Region of Africa and particularly Uganda experience recurrent cholera outbreaks that lead to considerable mortality morbidity. We evaluated epidemiology population characteristics better target prevention control interventions contribute its elimination from those communities.
Despite the many examples where simulation has successfully demonstrated its capability in modelling patient flow, there is little evidence of enduring widespread use. Bespoke academic projects provide scope for repeatable practical application and efforts to develop generic reusable solutions have neither clearly identified end users nor fully appreciated their multifaceted requirements. Influenced by a review existing findings recommendations addition customised survey prospective users,...
Long waiting times for elective hospital treatments are common in many countries. This study seeks to address a deficit the literature concerning effect of long waits on wider consumption healthcare resources.
Federated Learning (FL) is a decentralized machine learning approach that enables collaborative model training across distributed data sources while ensuring privacy. Unlike traditional centralized approaches, FL allows multiple clients (e.g., mobile devices, IoT sensors, and hospitals) to train global without sharing their raw data. This survey provides comprehensive overview of FL, discussing its fundamental concepts, architecture, algorithms, optimization techniques. We highlight the...
Background: Previous studies have indicated that crowding within the Emergency Department (ED) is associated with longer lengths of stay in ED and higher mortality. Boarding, time patients spend waiting for an inpatient bed after assessment, represents a clinically unproductive delay, occupies scarce resources. We aimed to explore impact medical boarding not only on their outcomes but also indirectly other awaiting ambulances. Methods: A retrospective cohort study using routine data 3 EDs...

Three simple, low cost aerodynamic drag reduction devices have been developed for application to the trailer of a tractor-trailer truck. The three undergone extensive operational testing where they amassed over 85,000 miles use. These technologies shown combined fuel savings 10% at an average speed 47.5 mph. This improvement in economy correlates equivalent approximately 30% with corresponding coefficient 0.45. Observations and anecdotal evidence from test activity that addition these...
Abstract Crown ethers are small, cyclic polyethers that have found wide‐spread use in phase‐transfer catalysis and, to a certain degree, protein chemistry. readily bind metallic and organic cations, including positively charged amino acid side chains. We elucidated the crystal structures of several protein‐crown ether co‐crystals grown presence 18‐crown‐6. then employed biophysical methods molecular dynamics simulations compare these complexes with corresponding apoproteins similar...
In an early stage of the COVID-19 outbreak, hospitals in England were asked to postpone elective treatments order accommodate expected demand for related admissions. This study aims forecast extent which waiting times could increase as a result these measures, and estimate level effort required restore performance pre levels. A time-driven simulation is configured calibrated based upon conditions February 2020. As worst case scenario, where restrictions on care extend twelve months treatment...

An assessment of the role fluid dynamic resistance and/or aerodynamic drag and relationship to energy use in United States is presented. Existing data indicates that 16% total consumed used overcome transportation systems. Application existing pressure reduction technologies all ground vehicles within will reduce yearly costs by 20 billion dollars.

Two methods for the addition of pendent dialkyl phosphonate units onto aryloxyphosphazenes, at both polymeric and cyclic trimer levels, are described. Sodium organophosphites or halogenated organophosphates were used as phosphonating agents allowed to react with bromomethylene- lithio-functionalized respectively. Phosphonation bromomethylene−phenoxy side groups proceeded ∼100% conversion, while phosphonation via lithiophenoxy intermediates yielded 80−85% conversion. The presence a direct...
