Adaptation to selective pressures is crucial for clinically important pathogens establish epidemics, but the underlying evolutionary drivers remain poorly understood. The current epidemic of carbapenem-resistant Klebsiella pneumoniae (CRKP) poses a significant threat public health. In this study we analyzed genome sequences 794 CRKP bloodstream isolates collected in 40 hospitals China between 2014 and 2019. We uncovered subclonal replacement predominant clone ST11, where previously prevalent...
Low power consumption, high sensitivity, and miniaturization of photodetectors are important features in future photonic systems. Therefore, photoelectrochemical-type with an independent supply, performance, compact structure have attracted great interest recent years. However, the development a photodetector excellent crystal quality sufficient contact area between nanorod arrays electrolyte environment remains challenge. In this work, self-powered solar-blind based on α-Ga2O3...
This study calculates the electronic structure and optical properties of intrinsic BiOIO3 X-BiOIO3 (X = As, Se, or Te) using PBE (Perdew–Burke–Ernzerhof) MBJ (Modified Becke–Johnson) functionals based on density functional theory, with showing better correlation experimental values. The systems exhibit relative stability under potential show crystal lattice distortion compared to BiOIO3, creating localized differences that enhance polarization adjust bandgap. Doping reduces bandwidth...
ABSTRACT This study utilized the cotton wool part of cigarette butts as a biomass precursor to synthesize ZnO@C‐NA composite heterojunction (ZnO attached three‐dimensional dendritic structure carbon nanotubes) through simple liquid phase deposition method. The ZnO and C‐NA has rich redox active sites large specific surface area. Compared with nanotube (C‐NA) anode DS), reversible capacity is 627 mAh/g (200 cycles, 0.1 A) 550 (1000 1 A). synergistic effect zinc oxide component effectively...
Abstract We systematically synthesized mixed-halide hybrid perovskite CH 3 NH Pb(Br x I 1−x ) (0 ≤ 1) crystals in the full composition range by a solvothermal method. The as-synthesized retained cuboid shapes, and crystalline structure transitioned from tetragonal phase to cubic with an increasing Br-ion content. photoluminescence (PL) of exhibited continuous variation red (768 nm) green (549 volume ratio HBr (V %), corresponding bandgap 1.61 eV 2.26 eV. Moreover, changed nonlinearly as...
CdTe nanocrystalline thin films have been prepared on glass, Si and Al2O3 substrates by radio-frequency magnetron sputtering at liquid nitrogen temperature. The crystal structure morphology of the were characterized X-ray diffraction (XRD) field-emission scanning electron microscopy (FESEM). XRD examinations revealed that glass had a better quality higher preferential orientation along (111) plane than Al2O3. FESEM observations continuous dense substrates. Optical properties deposited for...
CH3NH3PbX3 (X = I, Br and Cl) crystals have been successfully synthesized via a facile solvothermal method with different acids as halogen sources. Reaction conditions including concentration of the precursor, reacting temperature, time, sources, investigated. The results showed that CH3NH3PbI3 exhibit tetragonal phase change from normal cuboids to concave-faced by reaction conditions. CH3NH3PbBr3 CH3NH3PbCl3 show cubic structure cuboid. Moreover, photoluminescence spectra obtained sources...
A gait recognition method based on Fourier descriptors (FD) is put forward. First of all, by analyzing the cycle, sequence key frame could be subtracted from image sequence, then we can get movement contours human body through background abatement and use to handle frames profile compress data. At last, template matching, which classified recognized nearest neighbor law. The above experimented CASIA database. Experimental results demonstrate that this has good performance.
We fabricated an enhanced photoresponse AlGaN p–i–n photodetector by introducing a polarization electric field along the growth direction into active layer. The polarization-enhanced effect was realized reducing Al composition of p-AlGaN layer with respect to that i- and n-type layers. simulated results energy-band structure electric-field distribution indicate can increase greatly build-in in region hence improve collection efficiency photogenerated carriers. measured photocurrent spectra...
Location of the license plate region is most important step in recognition system. We propose a location algorithm based on histogram equalization. In this method, traditional improved by using equalization to enlarge intensity difference among objects and background. our experiments, different light condition images are tested. Experimental results demonstrate that proposed method can enhance contrast effectively accurate capture local strong exposure image.

Chinese Spelling Correction (CSC) is a challenging and essential task in natural language processing. In this study, we introduces new method for that addresses three unattended areas prior studies. Firstly, use an Implicit Knowledge Extraction Network to overcome limitations of conventional methods rely on explicit knowledge alone. Secondly, KL divergence limit the effect incorrect characters semantic understanding, ensuring consistent meaning. Finally, employ Cor-Det framework rather than...
