Manganese dioxide (MnO 2 ) often suffers from a slow electron transport, and so improving the charge transport capability of MnO is imminent. In here, crossed nanosheets grown on carbon cloth (CC) are fabricated firstly subsequently coated with layer polypyrrole (PPy) to prepare CC/MnO /PPy (CC/MP) electrode. At 1 A g −1 , prepared electrode able deliver specific capacitance 328 F . The flexible asymmetric supercapacitor consists CC/MP CC/activated (CC/AC) separately as positive negative...
A novel diaphragm-based miniature optical fiber pressure sensor has been shown to work at temperatures up 700/spl deg/C with a sensitivity of 2.93 nm/psi and resolution 0.01 psi (68.9 Pa). passive temperature compensation scheme was used reduce the dependence 0.0076 psi//spl (52.4 Pa//spl deg/C). The exhibited linear response in available testing range from 0 200 (1.38 MPa), being composed entirely fused silica, sensor's structure is very reliable, corrosion resistant, immune electromagnetic...
This study investigates the relationship between absolute eosinophil count (AEC) and percentage (EOS%) with response rates to immune checkpoint inhibitors (ICIs) in recurrent or metastatic head neck squamous cell carcinoma (R/M HNSCC) patients. The analysis included data from R/M HNSCC patients treated ICIs at Second Xiangya Hospital (2016-2021), assessing baseline characteristics, tumor specifics, immune-related adverse events, AEC, EOS%. correlation these factors ICI was evaluated using...
Coconut palms (Cocos nucifera L.) are globally significant with both economic and cultural value. Despite the increasing demand for coconut products, production is decreasing due to palm senility, pests, diseases. It has been estimated that over half of world’s need be replaced immediately. The industry acknowledged conventional propagation methods unlikely yield sufficient high-quality planting material. Therefore, tissue culture considered a potential solution this problem. By using...
Abstract Imaging plays a vital role in enabling the visualization and analysis of objects phenomena across various scientific disciplines industrial sectors, spanning wide range length time scales. This roadmap presents critical overview thirteen imaging techniques, which are organized into three thematic sections according to their applicability either solid, fluid, or both solid fluid targets. The objectives this highlight challenges provide perspectives for next-generation systems, can...
A nonlinear compensation method for matrix converter is proposed to compensate the voltage error between reference and actual output voltage. The caused by voltage-based commutation process analyzed, parasitic capacitor effect of on a forced investigated. It found that could reduce total process, it makes relate not only direction load current but also magnitude current. obtained considering switching pattern, then, general function on-state drop devices. effectiveness has been verified...
This paper describes an implementation and testing of a 5 kW matrix converter based on two-step voltage commutation. The primary objective this research effort is to develop the practical applications commutation strategy in converter. A prototype has been built using eighteen 60-A 1000-V discrete insulated gate bipolar transistors (IGBTs) controller DSP combination with FPGA. An improved used for guaranteeing safe control bidirectional switches at zero crossing input line without additional...
Mobile ad hoc networks and peer-to-peer share an important characteristic of self-organization. Due to the common nature, it is natural attractive for be deployed on MANET. However, their some different features, there lots work research in P2P MANET, such as architecture, resource discovery strategy, dissemination security privacy mechanism. This paper proposes a new algorithm based locality theory over mobile networks. Locality includes spatial locality, temporal content locality. It...
This paper presents a novel intrinsic fiber optic Fabry-Perot (FP) structure with micrometric diameter tip. With the FP cavity inside fiber, change in optical path length distance (OPD) caused by environment can be demodulated. such tiny protrusion, sensor inserted into micron size cells for intracellular measurements. label-free detection method is very useful biological areas as DNA hybridization detection. It provides valuable tool studies that have applications ranging from medicine to...
The switching losses of a AC-DC matrix converter (MC) is determined not only by the physical characteristics devices but also operation principle. This paper studies space vector modulated MC. conventional patterns are compared using measurement-based analytical model. Then two optimal strategies proposed to reduce losses. Simulation and experiment implemented for evaluation. results verified effectiveness strategies.
