Dear Editor,This letter deals with the stabilization problem of nonlinear stochastic systems via self-triggered impulsive control(STIC), where the timing of impulsive control actions is not dependent on continuous state monitoring. In contrast to the existing self-triggered control method, novel self-triggered mechanism(STM) is proposed by incorporating a waiting time for stabilizing impulses. This allows for direct prediction of the next impulsive instant.

猪繁殖与呼吸综合征病毒(PRRSV)感染引起的繁殖障碍在妊娠早期表现为母猪受胎率低、不规律返情及孕早期流产;怀孕后半期流产、早产,产死胎、木乃伊胎及弱仔等。先天感染的仔猪抵抗继发感染的能力低,可持续排毒并感染周围的阴性动物。PRRSV穿过胎盘屏障感染胎儿很可能是经巨噬细胞/单核细胞介导的,并在母胎界面造成病理损伤,病毒在胎儿着床点的复制可能是导致胎儿死亡和母猪流产的原因。预防PRRSV垂直传播必须控制母猪感染PRRSV,缩短已感染母猪的病毒血症持续时间,此外,通过生物安全、限制猪群流动和严格的消毒措施控制水平传播,通过疫苗免疫和药物保健消除易感动物。作者概述了妊娠各阶段母猪感染PRRSV发生垂直传播的情况及其后续的繁殖障碍。

Accurate localization ability is fundamental in autonomous driving. Traditional visual localization frameworks approach the semantic map-matching problem with geometric models, which rely on complex parameter tuning and thus hinder large-scale deployment. In this paper, we propose BEV-Locator: an end-to-end visual semantic localization neural network using multi-view camera images. Specifically, a visual BEV(bird-eye-view) encoder extracts and flattens the multi-view images into BEV space. While the semantic map features are structurally embedded as map query sequences. Then a cross-model transformer associates the BEV features and semantic map queries. The localization information of ego-car is recursively queried out by cross-attention modules. Finally, the ego pose can be inferred by decoding the transformer outputs. This end-to-end model speaks to its broad applicability across different driving environments, including high-speed scenarios. We evaluate the proposed method in large-scale nuScenes and Qcraft datasets. The experimental results show that the BEV-Locator is capable of estimating the vehicle poses under versatile scenarios, which effectively associates the cross-model information from multi-view images and global semantic maps. The experiments report satisfactory accuracy with mean absolute errors of 0.052 m, 0.135 m and 0.251° in lateral, longitudinal translation and heading angle degree.
