Abstract Endogenous electric field is considered to play an important role in promoting collective migration of epidermis the wound centre. However, most studies are focused on effect bioelectric movement and single epithelial cell; molecular mechanisms about epidermal monolayers remain unclear. Here, we found that EFs dramatically promoted HaCaT cells towards anode, activated sheddase activity ADAM17 increased phosphorylation level EGFR. Moreover, EGFR HB‐EGF shedding were significantly...

Support vector machine (SVM) can be seen as, a special binary classification method. The original model is quadratical programming with linear inequalities constraints. It very important issue that how to get the optimal solution of SVM model. In this paper, new method proposed. constraints are moved away from optimization by using approximation in feasible space. One control parameter smoothing function used smoothen objective unconstrained performance investigated. By theory proof,...

False data injection attacks (FDIA) destroy the integrity of information transmission by evading bad detection mechanism, and thus affects stability power cyber-physical systems (PCPS). Existing studies simply introduce complex neural network models for FDIA detection, ignoring spatial-temporal correlation interpretability networks. As a result, accuracy reliability false may be negatively affected. To address challenges above, this paper proposes an interpretable deep learning framework...
