Abstract: Antibiotic-resistant bacteria present a great threat to public health. In this study, the synergistic effects of antimicrobial peptides (AMPs) and antibiotics on several multidrug-resistant bacterial strains were studied, their azithromycin (AZT)-resistance genes analyzed determine relationships between resistance these effects. A checkerboard method was used evaluate AMPs (DP7 CLS001) (gentamicin, vancomycin [VAN], AZT, amoxicillin) clinical ( Staphylococcus aureus , Pseudomonas...
ABSTRACT To design and discover new antimicrobial peptides (AMPs) with high levels of activity, a number machine-learning methods prediction have been developed. Here, we present method that can identify novel AMPs are highly similar in sequence to known but offer improved activity along lower host cytotoxicity. Using previously generated AMP amino acid substitution data, developed an contribution matrix contained value for each position the model peptide. A series were designed this method....
Aimed at infinite horizon optimal control problems of discrete time-varying nonlinear systems, in this paper, a new iterative adaptive dynamic programming algorithm, which is the discrete-time policy iteration (DTTV) developed. The law designed to update value function approximates index performance. admissibility analyzed. results show that non-increasingly convergent Bellman-equation solution. To implement neural networks are employed and implementation structure established, avoids...
Vulnerability analysis is the premise of operational risk management and control for large-scale complex urban rail transit network (URTN) under operation interruption important stations. The temporary one station in an emergency may lead to cascading failure paralysis whole URTN due load other stations exceeding limited capacity. priority proposed by combining its location function URTN. In addition, focusing on travel behaviour passengers synergy public transport networks, a novel...
Vulnerability assessment plays a crucial role in the management of complex and large-scale urban rail transit networks (URTNs). Even temporary disruption may paralyze an entire public transportation network under cascading failure. In terms vulnerability URTN, most studies have focused on changes URTN topological characteristics travel costs disturbances, thereby neglecting impact alternative modes passenger flow redistribution within URTN. Therefore, this study, considering redistribution,...
With the emergence of all kinds location services applications, massive data are collected in real time. A hierarchical fast density clustering algorithm, DBSCAN(density based spatial applications with noise) algorithm on Gauss mixture model, is proposed to detect clusters and noises arbitrary shape data. First, gaussian model used fit probability distribution dataset determine different levels; then, DBSCAN subdatasets levels locally clustered, at same time, appropriate seeds selected...
To improve the accuracy and efficiency of fault data identification traffic detectors is crucial in order to decrease probability unexpected failures intelligent transportation system (ITS). Since convolutional recognition based on flow three-parameter law has a poor capability for multiscale data, PCA (principal component analysis) adopted identification. This paper proposes detection models model, MSPCA (multiscale principal model improved respectively. In rate detectors’ combines wavelet...
This study aims to investigate the effect of ring plate on mechanical performance X-type tube-gusset joints. The failure modes, ultimate strengths, and mechanisms X-joints with plates were investigated through experiments finite element analyses. results indicated that chord within effective range constituted primary bearing structure X-joint. Increases in thickness width increased strength By considering forces braces as a superposition bending moment force acting gusset X-joint, simplified...
