0Cr16Ni5Mo1 super martensitic stainless steel has excellent weldability and is an economical material with a high life cycle low cost, but there are few researches applications of this in additive manufacturing. In order to realize the application large-area laser cladding technology, multi-track lap was studied. work, multi-physical finite element model multi-layer established, taking into account thermodynamic processes such as phase transition, Marangoni convection, buoyancy. The flow...

This study aims to investigate how the level of semantic relevance influences effects test on associative memory through bottom-up cognitive processes. manipulated levels relevancy using synonym and nonsynonym pairs in a three-phase testing effect paradigm (an initial encoding phase, cued-recall as retrieval practice, final phase) explore recognition by processes event-related potential (ERP). The behavioral results suggested that practice (relative restudy) significantly facilitated high...

Previous studies have found differences in the cognitive and neural mechanisms between reappraisal expression suppression regulation of various negative emotions recognition regulated stimuli. However, whether these are valid for sadness remains unclear. As such, we investigated effect on sad scenes adopting event-related potentials (ERPs). Twenty-eight healthy undergraduate graduate students took part this study. In phase, participants were asked to down-regulation, expressive suppression,...

Abstract Introduction Numerous studies have explored the effect of cognitive reappraisal before or after emotion‐inducing events. However, only a few examined influence regulatory timing on effectiveness reappraisal. Thus, aim this study was to investigate role and goals in regulation, which would help promote specific application emotion regulation. We hypothesized that decrease be more effective when initiated early rather than late, but increase emotional high‐activation phase. Methods...

Previous studies on the joint effect of reward motivation and emotion memory retrieval have obtained inconsistent results. Furthermore, whether how any such might vary over time remains unclear too. Accordingly, using event-related potential (ERP) measurement high temporal resolution, our study investigates cognitive brain mechanisms monetary affecting processes episodic memory. Twenty undergraduate graduate students participated in research, study's behavioral results indicated that...

Previous studies have suggested that the effects of reward on memory processes are affected by certain factors, but it remains unclear whether at retrieval recognition influenced emotion. The event-related potential was used to investigate combined effect and emotion its neural mechanism. behavioral results indicated improved performance under positive negative emotional conditions. there were significant interactions between in average amplitude during recognition, from frontal parietal...

Previous studies have found that reward effect is stronger for more difficult to retrieve items, but whether this holds true the associative memory remains unclear too. We investigated effects and neural mechanisms of different unitization depths sets on encoding using event-related potentials (ERPs), which were recorded through a Neuroscan system with 64-channel electrode cap according international 10-20 system, five electrodes (Fz, FCz, Cz, CPz, Pz) selected analysis. Thirty healthy...

Objective To investigate the security characteristics of rural young boarding pupils and its influencing factors. Methods 210 265 non-boarding Huojia in Henan were tested by questionnaires, including a self-developed questionnaire, questionnaire adolescent mental resilience scale. Results ①The scores interpersonal security(25.99±5.53), determine control sense factor (24.63±6.17) total security(50.62±10.37) statistically lower than (27.36±6.38, 26.00±6.55, 53.36±11.77, P 0.05)....

A DOA-GRU-based surface roughness prediction method was developed to address the problems of poor generalization and low accuracy traditional CNC milling models. The static data such as spindle speed feed dynamic force signal were obtained; DOA-GRU obtained by optimizing network structure parameters Gated Recurrent Unit (GRU) neural using Dingo Optimization Algorithm (DOA); features selected Response Surface Methodology (RSM) extracted adaptively, then fused shallow build model. experiment...

High-speed dry grinding has the characteristics of high processing efficiency and clean environment. The high-speed method meets requirements green efficient development national manufacturing industry. However, inappropriate cutting parameters seriously affect surface quality workpiece cause to be scrapped. Therefore, this paper proposed an optimization based on combination improved extreme learning machine neural network (ELM) for milling roughness prediction model genetic algorithm (GA)....

Objective To revise Core Self-Evaluation Scale (CSES) and examine its reliability validity in employees undergraduates China. Methods The adaptation of the scale was gotten by way translation back-translation. 400 272 were tested questionnaires, their data used to evaluate scale. Results In undergraduates, Cronbach' s coefficient CSES respectively 0.71,0.81, test-retest 0.81,0.84. results confirmatory factor analysis showed that single model more fit for revised CSES. had good convergent...

Abstract Previous studies have explored the effects of retrieval reward and depth processing in encoding on recognition, but it remains unclear whether how during influence recognition. We investigated effect neural mechanisms recognition using event-related potentials (ERPs) this study. In study phase, participants were asked to perform two tasks: congruity-judgment (deep processing) size-judgment (shallow no-reward conditions. The test phases included object (item) background (source)...

Objective To explore the relationship between responsibility and social adaptation of left-behind middle school students to provide evidence for mental health education children. Methods 290 were selected by cluster-random-sampling. All them assessed students' adaptability scale (SAS-SSS), inventory parent peer attachment(IPPA) high responsibility. Results The correlation responsibility, attachment behavior significant(r=0.39, r=0.56, P<0.01). There significant differences...

Objective To study anxiety and depression among the abused children their association with psychological resilience. Methods Self-rated questionnaires including screen questionnaire of child abuse(SQCA), for related emotional disorder(SCARED), self-rating scale children(DSRSC), Resilience Scale General information were applied to 447 children. Results (1)The score rating SCARED DSRSC in group children(respectively(20.39±12.79), (11.65±5.44)and 40.26%, 27.27%)was higher than that...
