Online object tracking is a challenging problem as it entails learning an effective model to account for appearance change caused by intrinsic and extrinsic factors. In this paper, we propose novel online algorithm with sparse prototypes, which exploits both classic principal component analysis (PCA) algorithms recent representation schemes models. We introduce <i xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">l</i> <sub...
We investigated the prevalence and transmission of NDM-producing Enterobacteriaceae in fecal samples geese environmental from a goose farm southern China. The were cultivated on MacConkey agar plates supplemented with meropenem. Individual colonies examined for blaNDM, blaNDM-positive bacteria characterized based whole-genome sequencing (WGS) data Illumina Oxford Nanopore Technologies (ONT) platforms. Of 117 analyzed, carriage rates New Delhi metallo-β-lactamase (NDM)-positive 47.1, 18, 50%...
To investigate the prevalence and molecular characteristics of fosA3 fosA7 among Salmonella isolates.Five hundred fifty-one isolates collected from food animals in China during 2016-19 were screened for fos genes. The drug resistance, serovars, clonal relationships genetic environments fosA compared between fosA7- fosA3-positive Salmonella.A relatively high (9.26%) (6.53%) was identified. associated with high-level fosfomycin resistance (≥512 mg/L), while conferred low-level that independent...
ABSTRACT The dissemination of antibiotic resistance genes (ARGs) through plasmids is a major mechanism for the development bacterial antimicrobial resistance. adaptation and evolution mechanisms multidrug-resistant (MDR) with their hosts are not fully understood. Herein, we conducted experimental 244 kb MDR plasmid (pJXP9) under various conditions including no antibiotics mono- or combinational drug treatments colistin (CS), cefotaxime (CTX), ciprofloxacin (CIP). Our results showed that...
Abstract This paper presents a new two‐step color transfer method which includes mapping and detail preservation. To map source colors to target colors, are from an image or palette, the proposed similarity‐preserving algorithm uses similarities between pixel dominant as existing algorithms emphasizes colors. Detail preservation is performed by ℒ0 gradient‐preserving algorithm. It relaxes large gradients of sparse pixels along region boundaries preserves small within regions. The similarity...
We identified fosA3 at a rate of 2.6% in 310 Salmonella isolates from food animals Guangdong province, China. The gene was genetically linked to diverse antibiotic resistance genes (ARGs), including mcr-1, blaCTX-M-14/55, oqxAB, and rmtB These combinations were embedded heterogeneous fosA3-containing multidrug regions on the transferable ST3-IncHI2 F33:A-:B- plasmids chromosome. This indicated great flexibility cotransmission with multiple important ARGs among species.
After analyzing the speckle model of SAR, a SAR image de-noising method based on Wavelet-Contourlet transform and principal component analysis is presented. Compared with Wavelet Contourlet transform, can express images more sparsely obtain structure better. Most existing methods for rely accurate estimation noise variance. However, variance very difficult in domain. Propose new analysis. Simulation results also corroborate that proposed algorithm efficient performs significantly better...

These were multidrug-resistant most simultaneously resistant to fosfomycin, cefotaxime, ciprofloxacin amikacin. Consistently, all also possessed bla CTX–M– 14 , CMY– 65 / 122 aac(6’)-Ib-cr qnrS1 qnrB13/6/38 rmtB . -positive...
This study aimed to determine the prevalence and transmission characteristics of New Delhi metallo β-lactamase (NDM)-producing Escherichia coli from ducks in Guangdong, China. In this study, a total 28 NDM-producing E. isolates were recovered 88 unduplicated diseased duck samples (31.8%) veterinary clinics Guangzhou, Foshan, Qingyuan, Huizhou. Two variants, bla NDM−1 NDM−5 , detected latter was present 89.6% (25/28). Multilocus sequence typing (MLST) analysis indicated that these possessed...
Salmonella enterica can lead to intestinal diarrhea, and the emergence spread of cephalosporin-resistant have brought great challenges clinical treatment. Therefore, this study investigated prevalence transmission bla CTX-M genes among S. Typhimurium from diarrhoeal outpatients in Guangdong, China, 2010 2017.

As an important image editing technique, color transfer plays role in processing, which changes the original according to another image's characteristics. This paper presents a new interactive local method. The user draws strokes specifying target region needed colors, can be segmented by improved classification method, and will transferred. boundary of result remedied matting. At end transfer, only pixels this is transferred, while others remain unchanged. experimental results show that our...

In this paper, we present a simple and novel approach for solving single image super-resolution (SISR) without external data set. Based on variant of gaussian process regression (GPR), SISR is formulated as multi-task problem in which each learning task refers to estimation the function patch. Unlike conventional methods, need specify form or determine many parameters using inefficient method, our proposed implicit defined by kernel all its model can be learned from training set...
