自100多年前鸡马立克病(mD)首次报道以来,人们一直致力于病原体及其防控策略的研究。近几年来,由于马立克氏病毒(mDV)的不断进化,引起诸多地区屡次暴发mD,如何改进预防措施显得刻不容缓,因此,必须了解病毒与宿主之间的相互作用。宿主的免疫系统与病毒的入侵与扩散息息相关,主要通过两种机制应对病毒入侵,作为机体第一道免疫防线的天然防御机制包括可溶性因子的分泌以及巨噬细胞和自然杀伤细胞等免疫细胞的参与,天然免疫反应促使免疫系统形成特异的抵抗mDV的抗体和细胞免疫应答。除免疫系统外,遗传和表现遗传机制有助于鸡应答mDV感染。本文综述了目前对mDV诱导的免疫应答的理解以及免疫应答的遗传因子。

failure detection is an essential task in industrial systems for preventing costly downtime and ensuring the seamlessoperation of the system. Current industrial processes are getting smarter with the emergence of Industry ***, various modernized industrial processes have been equipped with quite a few sensors to collectprocess-based data to find faults arising or prevailing in processes along with monitoring the status of *** diagnosis of rotating machines serves a main role in the engineering field and industrial production. Dueto the disadvantages of existing fault, diagnosis approaches, which greatly depend on professional experienceand human knowledge, intellectual fault diagnosis based on deep learning (DL) has attracted the researcher’sinterest. DL reaches the desired fault classification and automatic feature learning. Therefore, this article designs a Gradient Optimizer Algorithm with Hybrid Deep Learning-based failure Detection and Classification (GOAHDLfDC)in the industrial environment. The presented GOAHDL-fDC technique initially applies continuous wavelettransform (CWT) for preprocessing the actual vibrational signals of the rotating machinery. Next, the residualnetwork (ResNet18) model was exploited for the extraction of features from the vibration signals which are thenfed into theHDLmodel for automated fault detection. finally, theGOA-based hyperparameter tuning is performedtoadjust the parameter valuesof theHDLmodel *** experimental result analysis of the GOAHDL-fD Calgorithm takes place using a series of simulations and the experimentation outcomes highlight the better resultsof the GOAHDL-fDC technique under different aspects.
