ABSTRACT While copper is an essential trace element in biology, pollution of groundwater from has become a threat to all living organisms. Cellular mechanisms underlying toxicity, however, are still not fully understood. Previous studies have shown that iron-sulfur proteins among the primary targets toxicity Escherichia coli under aerobic conditions. Here, we report that, anaerobic conditions, E. cells even more susceptible medium. Whereas addition 0.2 mM copper(II) chloride LB...

Shared-account cross-domain sequential recommendation (SCSR) task aims to recommend the next item via leveraging mixed user behaviors in multiple domains. It is gaining immense research attention as more and users tend sign up on different platforms share accounts with others access domain-specific services. Existing works SCSR mainly rely mining patterns recurrent neural network (RNN)-based models, which suffer from following limitations: 1) RNN-based methods overwhelmingly target...

The corrosion morphology and the mechanical behavior of corroded prestressing strands are investigated in present study. Nineteen obtained through controlling stress level, time chloride ion concentration under artificial climate conditions. A total 119 pits counted to investigate geometric pits. depth-width ratio parameter is first defined describe distribution law pits, which obeys lognormal distribution. tension test conducted strands. fracture micro-cracks steel wires observed by...

Reliable failure detection holds paramount importance in safety-critical applications. Yet, neural networks are known to produce overconfident predictions for misclassified samples. As a result, it remains problematic matter as existing confidence score functions rely on category-level signals, the logits, detect failures. This research introduces an innovative strategy, leveraging human-level concepts dual purpose: reliably when model fails and transparently interpret why. By integrating...

Vision-Language Models (VLMs), such as CLIP, have already seen widespread applications. Researchers actively engage in further fine-tuning VLMs safety-critical domains. In these domains, prediction rationality is crucial: the should be correct and based on valid evidence. Yet, for VLMs, impact of seldomly investigated. To study this problem, we proposed two new metrics called Prediction Trustworthiness Inference Reliability. We conducted extensive experiments various settings observed some...

This paper presents a running and obstacle-navigation control principle for an inspection robot, describes the development of system based on distributed expert (DES) electromagnetic shielding system. The robot can run overhead ground wires navigate obstacles (counterweights, clamps towers) autonomously, inspect damage 500KV extra-high voltage power transmission line equipment (towers, lines, insulators). field experiments real show has possessed main functions tasks.

This paper presents an obstacle-navigation strategy for a wire-suspend robot power transmission lines based on novel movement mechanism. The kinematics of the mobile and process control are analyzed in detail. A realtime expert system with hybrid architecture C Language Integrated Production System (CLIPS) is described as system. developed by CLIPS language, so it has powerful logical reasoning ability data processing ability. And can instruct to navigate obstacles autonomously overhead...

To explore the hot tensile deformation characteristics of aged and homogenized AZ61Ce magnesium alloy sheets, constitutive equation, initial condition dynamic recrystallization (DRX) microstructure are investigated in terms uniaxial testing a temperature range 473–723 K strain rate 0.003–0.1 s−1. Dynamic aging (DSA) is easily caused under low conditions for sheet, while its counterpart not sensitive to DSA these conditions. The equations both sheets peak stress established by regression...

In order to improve the interfacial wettability between Cu and β-SiC, electroless plating was employed deposit a copper film on β-SiC particles. The β-SiC/Cu composites with different volume fraction ( from 30% 60% ) were fabricated by hot-press sintering technique. microstructures, bending strengths investigated SEM tensile machine. results showed that uniform continuous coating particles can be obtained after plating. With increase of particles, strength decreased gradually. fractographs...

Electroless plating technology was applied in order to improve the poor wettability between copper and SiC. β-SiC (w+p) /Cu composites were fabricated by hot-press sintering.
