从认识论的高度阐明失效、失效分析和预防在人类科学技术发展中的属性、地位和作用。失效分析和预防具有多学科交叉综合的属性,它的发展依赖于应用学科、应用基础学科、甚至于基础学科的发展,但又对它们的发展起重要反转作用和影响。因此,它是科学技术第一生产力中最积极、最活跃的因素之一。从方法论的角度进一步叙述了失效分析与失效预防之间的辩证关系。失效分析是一种事后的逆向思维过程,它是从异常现象(结果)到因素(模式、原因和机理)的反向科技探索,而失效预防(安全评定)则是从因素到结果的一种事先的正向思维过程。逆向思维与正向思维协同并用,事后分析转化为事先分析,构成科学技术研究活动和科技发展的全过程,两者不可偏废。综述了失效分析和失效预防(安全评定)的主要内容、技术、方法和它们的发展趋势,并提出它们与无损检测技术之间的关系。

CHARACTERISTICS OF HERBIVORY/WOUND-ELICITED ELECTRICAL SIGNAL TRANSDUCTION IN TOMATO
《农业科学与工程前沿(英文)》 2021年 第8卷 第2期
Electrical signals commonly occur in plants in response to various environmental changes and have a dominant function in plant acclimation. The transduction of wound-elicited electrical signals in the model plant species Arabidopsis has been characterized but the characteristics of electrical signal transduction in response to herbivory or wounding in crop species remain unknown. Here, the features of electrical signals elicited by insect herbivory and wounding in tomato were investigated. Unlike those in Arabidopsis, wounding tomato leaves did not cause leaf-to-leaf electrical signal transduction. In contrast, electrical signals elicited in response to petiole wounding were stronger and more strongly transduced. Leaflet wounding also activated electrical signal transduction and jasmonic acid (JA) signaling within the whole compound leaf. It was also demonstrated that tomato glutamate receptor-like 3.3 (GLR3.3) and GLR3.5 mediated leaflet-to-leaflet electrical signal transduction. Herbivory-induced JA accumulation and Helicoverpa armigera resistance were reduced in glr3.3/3.5 plants. This work reveals the nature of electrical signal transduction in tomato and emphasizes the key roles of GLR3.3 and GLR3.5 in electrical signal transduction and JA signaling activation.

This paper describes the Brain Computer Interface (BCI) system and the experiments to allow post-acute (<3 months) stroke patients to use electroencephalogram (EEG) to trigger neuromuscular electrical stimulation (NMES)-assisted extension of the wrist/fingers, which are essential pre-requisites for useful hand function. EEG was recorded while subjects performed motor imagery of their paretic limb, and then analyzed to determine the optimal frequency range within the -rhythm, with the greatest attenuation. Aided by visual feedback, subjects then trained to regulate their -rhythm EEG to operate the BCI to trigger NMES of the wrist/finger. 6 post-acute stroke patients successfully completed the training, with 4 able to learn to control and use the BCI to initiate NMES. This result is consistent with the reported BCI literacy rate of healthy subjects. Thereafter, without the loss of generality, the controller of the NMES is developed and is based on a model of the upper limb muscle (biceps/triceps) groups to determine the intensity of NMES required to flex or extend the forearm by a specific angle. The muscle model is based on a phenomenological approach, with parameters that are easily measured and conveniently implemented.
