Introduction Early and effective application of antimicrobial medication has been evidenced to improve outcomes patients with bloodstream infection (BSI). However, conventional microbiological tests (CMTs) have a number limitations that hamper rapid diagnosis. Methods We retrospectively collected 162 cases suspected BSI from intensive care unit blood metagenomics next-generation sequencing (mNGS) results, comparatively evaluate the diagnostic performance clinical impact on antibiotics usage...
The existence and uniqueness of the numerical invariant measure backward Euler--Maruyama method for stochastic differential equations with Markovian switching is yielded, it revealed that converges to underlying in Wasserstein metric. global Lipschitz condition on drift coefficients required by [J. Bao, J. Shao, C. Yuan, Potential Anal., 44 (2016), pp. 707--727] [X. Mao, G. Yin, Comput. Appl. Math., 174 (2005), 1--27] released. Under a polynomial growth imposed we show convergence rate...
Abstract Background Porcine epidemic diarrhea virus (PEDV), an enteric coronavirus, has become the major causative agent of acute gastroenteritis in piglets since 2010 China. Results In current study, 91 complete spike (S) gene sequences were obtained from PEDV positive samples collected 17 provinces China March 2020 to 2021. A phylogenetic analysis showed that 92.3% (84 out 91) identified strains belonged GII subtype, while 7.7% (7 categorized as S-INDEL like and grouped within GI-c clade....
In this article we introduce a number of explicit schemes, which are amenable to Khasminski's technique and particularly suitable for highly nonlinear stochastic differential equations (SDEs). We show that without additional restrictions those guarantee the exact solutions possess their boundedness in expectation with respect certain Lyapunov-type functions, numerical converge strongly finite-time. Moreover, based on convergence theorem nonnegative semimartingales, positive results about...

This work is concerned with permanence and ergodicity of stochastic Gilpin-Ayala models involve continuous states as well discrete events. A distinct feature that the parameter its corresponding perturbation are allowed to be varying randomly in accordance a random switching process. Necessary sufficient conditions extinction established, which much weaker than previous results. The existence unique stationary distribution also established. Our approach treats wider class systems, uses...
Porcine epidemic diarrhea virus (PEDV), an enteric coronavirus, has become the major causative agent of acute gastroenteritis in piglets since 2010 China. Given a raised interest mutation and recombination viral genomes, genetic antigenic characteristics PEDV should be continuously investigated. In current study, 91 complete spike (S) gene sequences were obtained from positive samples collected from17 provinces China March 2020 to 2021. A phylogenetic analysis showed that 92.3% (84 out 91)...
This paper investigates exponential stability problem of integral time-varying delay system. Based on a novel theorem, sufficient conditions for system are obtained in the form coupled linear matrix inequalities (LMIs). These cover some previous results as special cases when reduce to time-invariant cannot be directly from Theorem 1 given Li, Zheng, and Wang [(2016). Exponential analysis systems with multiple kernels. Journal Frankline Institute, 353, 1639–1653....
In this paper, a class of stochastic Lotka–Volterra system with feedback controls is considered. The purpose to establish some criteria ensure the globally dissipative in mean square. By constructing suitable Lyapunov functions as well combining Jensen inequality and It[Formula: see text] formula, sufficient conditions are established they expressed terms feasibility couple linear matrix inequalities (LMIs). Finally, main results illustrated by examples.
In this article we introduce several kinds of easily implementable explicit schemes, which are amenable to Khasminski's techniques and particularly suitable for highly nonlinear stochastic differential equations (SDEs). We show that without additional restriction conditions except those guarantee the exact solutions possess their boundedness in expectation with respect certain Lyapunov functions, numerical converge strongly finite-time. Moreover, based on nonnegative semimartingale...
This paper is devoted to dynamics of the Caputo‐type fractional FitzHugh–Nagumo equations (FHN) driven by Brownian motion (fBm). The existence and uniqueness mild solution for FHN are established, exponential synchronization finite‐time stochastic provided. Finally, numerical simulation time‐fractional perturbed fBm provided; effects order time derivative Hurst parameter on also revealed.

The stochastic logistic model with regime switching is an important in the ecosystem. While analytic solution to this positive, current numerical methods are unable preserve such boundaries approximation. So, proposing appropriate method for solving which preserves positivity and dynamical behaviors of model's very important. In paper, we present a preserving truncated Euler-Maruyama scheme model, taking advantages being explicit easily implementable. Without additional restriction...
