Abstract In 2009, a major outbreak of aseptic meningitis was noted in Linyi city, Shandong province, China. From June to September total 2,104 cases were involved this outbreak, and 98.6% patients <16 years age. To determine the pathogen 42 cerebrospinal fluid specimens collected from tested for cell culture, 17 (40.5%) enteroviruses isolated identified as Coxsackievirus B5 (CVB5). Homologous comparison indicated that these isolates had 0–7.7% nucleotide divergence with each other....
Enterovirus environmental surveillance on sewage from the city of Jinan, Shandong Province, China, was initiated in 2008. Thirty echovirus 6 (E6) strains-1 2008 and 29 2010-were isolated identified. Most E6 isolates (n = 21) came collected August 2010, revealing high local activity at that time. Interestingly, VP1 sequences most isolates, even same sewage, were not identical. Phylogenetic analysis revealed two lineages for these with 78.0 to 80.0% nucleotide identities one another, 94.8...
Environmental surveillance is an effective approach in investigating circulating enteroviruses and had been conducted the cities of Jinan Linyi since February 2008 April 2010, respectively. This study analyzed 46 sewage samples collected two 2011 found that echovirus 6 (E6) was predominant serotype, with 134 isolates (65 69 Linyi) from 23 (50%) samples. differs 2010 data 29 E6 only 3 Linyi. Phylogenetic analysis VP1 coding region showed all environmental to (n = 167) segregated into lineages...
This study discusses how to facilitate the barrier-free circulation of energy big data among multiple entities and balance ecosystem under government supervision using dynamic game theory. First, we define related concepts summarize recent studies developments data. Second, evolutionary theory is applied examine interaction mechanism complex behaviors between power grid enterprises third-party in ecosystem, with without government. Finally, a sensitivity analysis conducted on main factors...
P2P streaming applications are very popular on the Internet today. However, a mobile device in not only needs to continuously receive data from other peers for its playback, but also exchange control information (e.g., buffermaps and file chunk requests) with neighboring upload downloaded them. These lead excessive battery power consumption device.
China has embarked on a new round of power market reforms since 2015. Traditional generation groups (TPGGs), as important practitioners the electricity market, have taken various actions to adapt environment during recent years. Trading performance, most manifestation enterprise operation is evaluated in this paper, help TPGGs explore transition strategies improve business and achieve sustainable development. Considering multiple factors influencing TPGG trading hybrid framework based...
A novel high-voltage powerline inspection system is investigated, which consists of the cooperated ground vehicle and drone. The acts as a mobile platform that can launch recycle drone, while drone fly over for within limited endurance. This enables to inspect networks in very large area. Both vehicle&rsquo; route road network drone&rsquo;s routes along have be optimized improving efficiency, generates new two-layer point-arc routing problem. Two constructive heuristics are designed...
This paper investigates a multi-user multiple-input single-output (MISO) downlink communication system, which is assisted by dynamic-controlled Reconfigurable Intelligent Surface (RIS). Firstly, we formulate problem to optimize the active - and passive beamforming matrices with goal of maximizing sum rate (SR) all users under constraints Quality Service (QoS) requirements. A state selection matrix creatively introduced control number RIS elements used for reflection. And quantized phases are...
With the development of distributed renewable energy, a micro-energy grid (MEG) is an important way to solve problem energy supply in future. A two-stage optimal scheduling model considering economy and environmental protection proposed with high proportion system (RES) multiple storage systems (ESS), which risk measured by conditional value-at-risk (CVaR). The results show that (a) this can realize power various equipment, promote consumption operating cost 34873 USD. (b) dispatch...
In recent years, a lot of research work about the commutation failure inverter has been made by many scholars in domestic and abroad.
