Legionella is a significant pathogen responsible for community-acquired pneumonia and, less commonly, hospital-acquired pneumonia. pneumophila , the most prevalent species within genus, accounts 80%–90% of human infections, and often leads to severe complicated by multi-organ dysfunction. Omadacycline, novel tetracycline, has demonstrated in vitro activity against atypical pathogens, including L. ; however evidence regarding its application remains limited. In this paper, we report 3 cases...

Abstract China’s unique energy reserve structure abundant in coal and scarce crude oil natural gas has promoted heavy investment on the research development of clean chemical technologies during last two decades, which turned China into a heartland for demonstrating, developing, commercializing virtually every aspect new process technologies. Consequently, breakthroughs gasification, indirect direct coal-to-liquid (CTL) processes, methanol-to-olefins (MTO) are catching attention worldwide....

Artificial intelligence is currently in the center of attention legal professionals. In recent years, a variety efforts have been made to predict judicial decisions using different machine learning models, but no realistic performance comparison between them available. this paper, we conducted experiments comparing five well-known models: Ã-NN, logistic regression, bagging, random forests and SVM. Our experimental results show that SVM model outperforms other models over all settings,...

With the construction and development of modern smart cities, people’s lives are becoming more intelligent diversified. Surveillance systems increasingly play an active role in target tracking, vehicle identification, traffic management, etc. In 6G network environment, facing massive large-scale data information monitoring system, it is difficult for ordinary processing platform to meet this computing demand. This paper provides a governance solution based on environment. The shortcomings...

BACKGROUND Leukocyte telomere length (LTL) is regarded as a potential marker of biological aging. Oxidative stress plays major role in the rate telomeric DNA loss. The aim this study was to explore whether LTL shorter Chinese patients with premature coronary artery disease (PCAD) than non-CAD controls and determine relationship between oxidative shortening population. MATERIAL AND METHODS Patients for angiography were recruited. In total, 128 PCAD enrolled. Samples circulating leukocytes...

The growth of the e-commerce industry brings considerable waste. Chinese government has begun to pay attention development green e-commerce. We first analyze nexus between China’s and solid waste hope provide some insights into Considering cross-sectional dependence panel data, we adopt second-generation unit root cointegration tests. Furthermore, empirical results from DOLS show that EKC quadratic curve exists in Whole & Eastern Central Western China. In China, FDI will increase...

According to risk systems theory and the characteristics of chemical industry, an index system was established for assessment enterprises in industrial parks (CIPs) based on inherent source, effectiveness prevention control mechanism, vulnerability receptor. A comprehensive method catastrophe then proposed used analyze levels ten major Songmu Island CIP, China. principle equal distribution function, enterprise level divided into following five levels: 1.0 (very safe), 0.8 (safe), 0.6...

Abstract. Poultry layer houses are a significant source of particulate matter (PM) emissions, which potentially affect worker and animal health. Particulate characteristics, such as concentration size distribution inside houses, critical information for assessment the potential health risks development effective PM mitigation technologies. However, this its spatial seasonal variations lacking typical facilities. In study, two TSI DustTrak monitors (DRX 8533) an Aerodynamic Particle Sizer...

Although numerous advances have been made in information technology the past decades, there is still a lack of progress systems dynamics (ISD), owing to mathematical foundation needed describe and an analytical framework evaluate systems. The value ISD lies its ability guide design, development, application, evaluation large-scale system-of-systems (SoSs), just as mechanical theories engineering. This paper reports on breakthrough these fundamental challenges by proposing for space,...

This paper examines the essence that can help maintain sustainability of an e-commerce firm from perspective social network. We develop a comprehensive theory, using Penrose's (1959) resource-capability-firm's growth framework as integrative theoretical hook to link separate perspectives network structure, resource, and firm's sustainability. Then, this proposes three hypotheses related resource Striving for higher centrality, more complete membership diverse tie modalities, in addition...

Neural network-based approaches have become the driven forces for Natural Language Processing (NLP) tasks. Conventionally, there are two mainstream neural architectures NLP tasks: recurrent network (RNN) and convolution (ConvNet). RNNs good at modeling long-term dependencies over input texts, but preclude parallel computation. ConvNets do not memory capability it has to model sequential data as un-ordered features. Therefore, fail learn is able carry out high-efficient As each architecture,...

南京邮电大学信息材料与纳米技术研究院 有机电子与信息显示国家重点实验室 南京 210023) 摘要 十年来, 作为第三代有机发光二极管(organic light-emitting diodes, OLED)发光材料的热活化延迟荧光 (thermally activated delayed fluorescence, TADF)材料备受学术界和产业界的广泛关注.

Human activity, which usually consists of several actions (sub-activities), generally covers interactions among persons and/or objects. In particular, human involve certain spatial and temporal relationships, are the components more complicated evolve dynamically over time. Therefore, description a single action modeling evolution successive two major issues in activity recognition. this paper, we develop method for recognition that tackles these issues. proposed method, an is divided into...

This paper outlines a method that can be used for field reliability prediction using degradation data and environmental data. From different perspectives about the effects of dynamic environment on reliability, we proposed two methods to relate variables process. The modeling technique estimation are illustrated by an example predict failure time distribution product. result this study shows it is possible performance ADT results, if done carefully with good characterization conditions.

A new 'acid-free picking' method that adding cold rolling prior to hydrogen-reduction descaling was put forward in this study. The purpose of break the completeness oxide scale and increase reduction efficiency. Subsequently, high-temperature behavior on surface hot-rolled low carbon steel, which reacted with hydrogen after 10% deformation 20%H2-Ar at temperature range 400–850°C, investigated validate feasibility. mass loss specimens non-isothermal isothermal experiment clearly measured by...

An algorithm mapping from search tree given fulfil goal reusing case. architecture paper, could be reused generated during development technology improve efficiency...

The prediction of stock price movements is considered as a challenging task for financial time series analysis. difficulty predicting the trends lies in dynamic temporality and noise data. Echo State Network (ESN) popular model that considers series, but ESN often falls into dilemma over-fitting due to existence many unnecessary neurons hidden layer. To predict movements, this paper, we propose Multi-objective Diversified (MODESN). MODESN assigns diversity requirement such network able...
