Applications of intelligent technology in the evaluation of mutagenicity.

Bioassays are widely used in assessment of mutagenicity. Alternative methods have also been developed, including "intelligent evaluation", which depends on the quality of data, strategies, and techniques. CISOC-PSMT is an Ames test prediction system.

Perceived stress of COVID-19 pandemic and problematic mobile phone use during quarantine conditions among Chinese adolescents: a mediated moderation model.

The relation between perceived general stress and problematic mobile phone use (PMPU) has been well established. With the outbreak of the coronavirus disease (COVID-19), the present study was designed to examine the association between perceived stress of COVID-19 as a kind of event-related stress and PMPU, and the mechanisms underlying this relation. Participants were 724 adolescents ranging from 12 to 16 years old ( = 13.

Risk Assessment of the Possible Intermediate Host Role of Pigs for Coronaviruses with a Deep Learning Predictor.

Swine coronaviruses (CoVs) have been found to cause infection in humans, suggesting that Suiformes might be potential intermediate hosts in CoV transmission from their natural hosts to humans. The present study aims to establish convolutional neural network (CNN) models to predict host adaptation of swine CoVs. Decomposing of each and sequence was performed with dinucleotide composition representation (DCR) and other traits.

Tough Structural Adhesives with Ultra-Resistance to Both High and Cryogenic Temperature.

Structural adhesion at high temperature has been a challenge for organic adhesives, and the commercially available adhesives that can work at a temperature above 150 °C is rather limited. Herein, two novel polymers were designed and synthesized via facile strategy, which involves polymerization between melamine (M) and M-Xylylenediamine (X), as well as copolymerization of MX and urea (U). With well-balanced rigid-flexible structures, the obtained MX and MXU resins were proved to be outstanding structural adhesives at a wide range temperature of -196~200 °C.

Chitosan-tannin adhesive: Fully biomass, synthesis-free and high performance for bamboo-based composite bonding.

Inspired by phenol-amine chemistry of mussels, a synthesis-free and fully biomass adhesive composed of chitosan and tannin (CST) was successfully developed by a facile method. The performance of CST adhesive for bonding bamboo, wood and bamboo-wood substrates were tested. When 160 °C hot-press temperature was used, dry lap shear strength above 5.

Efficient 3D Deep LiDAR Odometry.

An efficient 3D point cloud learning architecture, named EfficientLO-Net, for LiDAR odometry is first proposed in this article. In this architecture, the projection-aware representation of the 3D point cloud is proposed to organize the raw 3D point cloud into an ordered data form to achieve efficiency. The Pyramid, Warping, and Cost volume (PWC) structure for the LiDAR odometry task is built to estimate and refine the pose in a coarse-to-fine approach.

Green credit and high-quality sustainable development of banks.

The impact of green credit on banks has been widely verified. This paper systematically combs the internal mechanism of the impact of green credit on high-quality sustainable development of banks and studies the relationship between green credit and high-quality sustainable development of banks by using unbalanced panel data of Chinese listed banks from 2007 to 2019. The results show that green credit will significantly promote high-quality sustainable development of banks, which remains valid after controlling for relevant variables and robustness test.

Academic procrastination precedes problematic mobile phone use in Chinese adolescents: A longitudinal mediation model of distraction cognitions.

Cross-sectional studies have documented a positive association between academic procrastination and problematic mobile phone use (PMPU). However, the specific predictive direction has remained controversial and the potential mechanisms underlying the association have not been rigorously evaluated. According to Davis's cognitive-behavioral model, Brand et al.

Why the Victims of Bullying Are More Likely to Avoid Involvement When Witnessing Bullying Situations: The Role of Bullying Sensitivity and Moral Disengagement.

Recent studies have suggested a link between bullying victimization and passive bystander behaviors, such as more outsider behaviors and fewer defender behaviors. However, little is known about the internal mechanism underpinning this relation. The present study aimed to examine the direct and indirect relationships between bullying victimization and two types of bystander behaviors (defender behavior and outsider behavior), considering the possible mediator role of bullying sensitivity and moral disengagement among Chinese adolescents.

Implicit Theories and Engagement in Math Among Chinese Adolescent Students: A Moderated Mediation Model of Intrinsic Value and Academic Self-Efficacy.

Recent studies have established associations between students' implicit theories and their academic engagement. However, there is still limited understanding of the potential mechanisms of this relation, and whether it works for students in the context of mathematics as well as in other subjects. The current study aimed to fill this gap by conducting a two-wave survey examining a moderated mediation model concerning the psychological mechanisms that account for the association between students' implicit theories and mathematics engagement.

How mathematics anxiety affects students' inflexible perseverance in mathematics problem-solving: Examining the mediating role of cognitive reflection.

Background: Too many students persevere in relying upon one (sometimes suboptimal) strategy for solving a wide range of problems, even when they know more efficient strategies. Although many studies have mentioned such phenomena, few studies have examined how emotional factors could affect this type of inflexible perseverance in strategy use.

Aims: To examine whether mathematics anxiety could affect students' inflexible perseverance in strategy use and whether this effect could be mediated by cognitive reflection, which is the ability to engage in deliberate reasoning.

Self-Esteem Moderates the Effect of Compromising Thinking on Forgiveness Among Chinese Early Adolescents.

Forgiveness contributes to positive social relationships, which is critical for individual development, particularly for early adolescents. Most previous studies focused on the unique roles of cognitive factors (e.g.

Parents' Phubbing and Problematic Mobile Phone Use: The Roles of the Parent-Child Relationship and Children's Self-Esteem.

An increasing number of mobile phone users check their phones at any time and place, even during in-person interactions. Such behaviors that interrupt social interactions have been described as phubbing. The present study focused on phubbing behaviors within the context of parent-child households and aimed to examine the associations among parents' phubbing, the parent-child relationship, children's self-esteem, and problematic mobile phone use (PMPU) by adolescents.

Psychological Distress and Problematic Mobile Phone Use Among Adolescents: The Mediating Role of Maladaptive Cognitions and the Moderating Role of Effortful Control.

Previous studies have documented that psychological distress is related to problematic mobile phone use (PMPU), and sporadic research has investigated the potential mechanisms underlying the association. Based on the cognitive-behavioral model of pathological Internet use (PIU), the self-control theory, and the problem-behavior theory, this study aimed to examine the mediating role of maladaptive cognitions toward mobile phones and the moderating role of effortful control between psychological distress and PMPU. Data were collected from 1,799 secondary school students (45.

Victim Sensitivity and Altruistic Behavior in School: Mediating Effects of Teacher Justice and Teacher-Student Relationship.

The current study aimed to explore how victim sensitivity influenced altruistic behaviors in school and to explore the mediating roles of teacher justice and teacher-student relationship. In 2018, we recruited 1,856 Chinese adolescents including 989 fourth graders ( = 10.35, SD = 0.
