The aetiological mechanism of gestational diabetes mellitus (GDM) has still not been fully understood. The aim of this study was to explore the associations between functional genetic variants screened from a genome-wide association study (GWAS) and GDM risk among 554 GDM patients and 641 healthy controls in China. Functional analysis of single nucleotide polymorphisms (SNPs) positively associated with GDM was further performed. Univariate regression and multivariate logistic regression analyses were used to screen clinical risk factors, and a predictive nomogram model was established. After adjusting for age and prepregnancy BMI, rs9283638 was significantly associated with GDM susceptibility (P < 0.05). Moreover, an obvious interaction between rs9283638 and clinical variables was detected (P
interaction < 0.05). Functional analysis confirmed that rs9283638 can regulate not only target gene transcription factor binding, but it also regulates the mRNA levels of SAMD7 (P < 0.05). The nomogram model constructed with the factors of age, FPG, 1hPG, 2hPG, HbA1c, TG and rs9283638 revealed an area under the ROC curve of 0.920 (95% CI 0.902–0.939). Decision curve analysis (DCA) suggested that the model had greater net clinical benefit. Conclusively, genetic variants can alter women's susceptibility to GDM by affecting the transcription of target genes. The predictive nomogram model constructed based on genetic and clinical variables can effectively distinguish individuals with different GDM risk factors. [ABSTRACT FROM AUTHOR]- Published

The visual perception system of humans is susceptible to cognitive influence, which implies the existence of cognitive perception. However, the specifical trigger for cognitive penetration is still a matter of controversy. The current study proposed that the cognitive processing priority over perceptual processing might be critical for inducing cognitive penetration. We tested this hypothesis by manipulating the processing priority between cognition and perception across three experiments where participants were asked to complete a size-judging task under different competing conditions between cognition and perception. To sum up, we proved that the cognitive processing priority over perceptual processing is critical for cognitive penetration. This study provided empirical evidence for the critical trigger for cognitive penetration. [ABSTRACT FROM AUTHOR]

Assertion is the use of declarative sentences to convey information, which necessitates meeting the "justified-belief norm" as a prerequisite. However, a significant amount of misinformation that did not meet these conditions was spread during COVID-19, leading to a reintroduction of the assertion norm. One possible hypothesis is that the threatening content of the misinformation influenced the perception of the norm. However, this remains unclear to researchers. Therefore, we conducted two experiments to investigate the effect of threatening content in information on individuals' perceptions of norms. In all the experiments, participants read backstories with and without threatening content, followed by answering assertion questions. It was observed that people do follow a looser assertion norm for information that contains threatening content. Additionally, further exploration revealed that threatening factors also lead individuals to more easily perceive the related content as truth and reduce the probability of being blamed. These two outcomes provide some explanation for the underlying mechanism of threatening factors' influence. The research results further refined the theory of assertion norms, offering a certain basis for information management. [ABSTRACT FROM AUTHOR]

9. Concurrent attention to hetero‐depth surfaces in 3‐D visual space is governed by theta rhythm.
- Author

Deng, Hongyu, Gao, Yuan, Mo, Lei, and Mo, Ce
- Abstract
When simultaneously confronted with multiple attentional targets, visual system employs a time‐multiplexing approach in which each target alternates for prioritized access, a mechanism broadly known as rhythmic attentional sampling. For the past decade, rhythmic attentional sampling has received mounting support from converging behavioral and neural findings. However, so compelling are these findings that a critical test ground has been long overshadowed, namely the 3‐D visual space where attention is complicated by extraction of the spatial layout of surfaces extending beyond 2‐D planes. It remains unknown how attentional deployment to multiple targets is accomplished in the 3‐D space. Here, we provided a time‐resolved portrait of the behavioral and neural dynamics when participants concurrently attended to two surfaces defined by motion–depth conjunctions. To characterize the moment‐to‐moment attentional modulation effects, we measured perceptual sensitivity to the hetero‐depth surface motions on a fine temporal scale and reconstructed their neural representations using a time‐resolved multivariate inverted encoding model. We found that the perceptual sensitivity to the two surface motions rhythmically fluctuated over time at ~4 Hz, with one's enhancement closely tracked by the other's diminishment. Moreover, the behavioral pattern was coupled with an ongoing periodic alternation in strength between the two surface motion representations in the same frequency. Together, our findings provide the first converging evidence of an attentional "pendulum" that rhythmically traverses different stereoscopic depth planes and are indicative of a ubiquitous attentional time multiplexor based on theta rhythm in the 3‐D visual space. The rhythmic theory of attention posits a time‐multiplexing machinery that samples each attentional target in alternation. Here, we show that attention traverses hetero‐depth surfaces in the same manner as for coplanar targets. These findings demonstrate, for the first time, the ubiquity of rhythmic attentional sampling beyond 2‐D visual scenes and extend the elegant concept of 'attentional spotlight' in a broader context.

Stanley et al. (2018) found that the consideration of reasons rarely induced people to change their moral decisions. We challenged this article by assuming what caused such a null or weak effect was that the persuasiveness of reasons provided to oppose the initial decisions was not strong enough. To verify our assumption, this study used Stanley et al.'s (2018) experimental paradigm and manipulated the levels of persuasiveness of reasons. The results revealed (1) that not only strong opposing reasons but also weak affirming reasons could induce changes in moral decision‐making and increase decision confidence after altering the decisions; (2) that people with a weak decision confidence tended to change their initial decisions after evaluation of reasons; and (3) that people who maintained their decisions after considering weak opposing reasons enhanced rather than reduced their decision confidence. Overall, these findings demonstrated that moral decision change was a composite outcome of the interaction among reason type, reason persuasiveness and initial decision confidence and that low‐quality argumentation had a boomerang effect on moral persuasion. This study re‐lifted the role of rational reasoning in moral decision‐making and revising, thus posing important amendments to Stanley et al.'s (2018) findings. [ABSTRACT FROM AUTHOR]

- Abstract
Time perception has been known to depend on the temporal frequency of the stimulus. Previously, the effect of temporal frequency modulation was assumed to be monotonically lengthening or shortening. However, this study shows that temporal frequency affects time perception in a non-monotonic and modality-dependent manner. Four experiments investigated the time distortion effects induced by modulation of temporal frequency across auditory and visual modalities. Critically, the temporal frequency was parametrically manipulated across four levels (steady stimulus, 10-, 20-, and 30/40-Hz intermittent auditory/visual stimulus). Experiment 1, 2, and 3 consistently showed that a 10-Hz auditory stimulus was perceived as shorter than a steady auditory stimulus. Meanwhile, as the temporal frequency increased, the perceived duration of the intermittent auditory stimulus was lengthened. A 40-Hz auditory stimulus was perceived as longer than a 10- Hz auditory stimulus, but did not differ significantly from a steady one. Experiment 4 showed that, for the visual modality, a 10-Hz visual stimulus was perceived as longer than a steady stimulus, and the perceived duration was lengthened as temporal frequency increased. This study demonstrated that within the scope of the temporal frequencies examined in this study, there were differential distortion effects observed across sensory modalities. [ABSTRACT FROM AUTHOR]

13. Optimal IC Task Mapping to Maximize QoS on Heterogeneous Multicore Systems

- Abstract
Heterogeneous multicore architectures have become one of the most widely used hardware platforms for embedded systems, where time, energy, and system QoS are the major concerns. The Imprecise Computation (IC) model splits a task into mandatory and optional parts, allowing the trade-off of the above issues. However, existing approaches, to maximize system QoS (Quality-of-Service) under time or energy constraints, use a linear function to model system QoS. Therefore, they become unsuitable for general applications, whose QoS is modeled by a concave function. To deal with this limitation, this brief addresses the Mixed-Integer Non-Linear Programming (MINLP) problem of mapping IC tasks to a set of heterogeneous cores by concurrently deciding which processor executes each task and the number of cycles of optional tasks (i.e., task allocation and scheduling), under real-time and energy supply constraints. Furthermore, as existing solution algorithms either demand high time complexity or only achieve feasible solutions, we propose a novel approach based on problem transformation and dual decomposition that finds an optimal solution while avoiding high computational complexity. Simulation results show that the proposed approach achieves 98% performance of the optimization solver Gurobi, but only with 19.8% of its computation time.

FACE perception , *PERCEPTION testing , *SADNESS , *AFFECT (Psychology) , *REALISM , *AVERSION - Abstract
AbstractAffective feelings naturally infuse individuals’ perceptions, serving as valid windows onto the real world. The
affective realism hypothesis further explains how these feelings work: as properties of individuals’ perceptual experiences, these feelings influence perception. Notably, this hypothesis based on affective feelings with different valences has been substantiated, whereas the existing evidence is not compelling enough. Moreover, whether specific affective feelings can be experienced as properties of target perception remains unclear. Addressing these two issues deepens our understanding of the nature of emotional representation. Hence, we investigated the affective realism hypothesis based on affective feelings with different valences and specific emotions, comparing it with the affective misattribution hypothesis. In Experiment 1, we examined the effects of affective feelings with various valences on targets’ perception through the AM (1a) and CFS paradigms (1b). In Experiment 2, we investigated the effects of affective feelings with anger, sadness, and disgust using similar methods. Results from Experiments 1a and 1b consistently indicated significant differences in valence ratings of neutral faces under emotional contexts with varying valences. Experiment 2a revealed significant differences in specific emotion ratings of neutral faces under different specific emotional contexts in the AM paradigm, whereas such differences were not observed in the CFS paradigm in Experiment 2b. We concluded that affective feelings with different valences, rather than specific emotions, can be experienced as inherent properties of target perception, validating the affective realism hypothesis. These findings supported the view that the nature of emotional representation should be described as affective dimensions. [ABSTRACT FROM AUTHOR]- Published

- Abstract
The objective of this study is to assess the prevalence of antibiotic-resistant genes (ARGs) in the intestines of infants and the factors affecting their distribution. Breast milk and infant stool samples were collected from nine full-term, healthy mother-infant pairs. The bacterial distribution and various types of ARGs present in the samples were analyzed using metagenomic next-generation sequencing. Over a period spanning from 2 to 240 d after birth, a total of 273 types of ARGs were identified in both infant feces and breast milk, exhibiting a trend of increasing prevalence over time. High concentrations of representative ARG populations were identified in the intestines of infants, especially at 12-15 d after birth. These populations included APH3-Ib, tetW/N/W, mphA, and Haemophilus influenzae PBP3, and multiple ARG Escherichia coli soxS that were resistant to common clinically used aminoglycoside, tetracycline, macrolide, and beta-lactam antibiotics. Gammaproteobacteria and Bacilli, especially Enterococcus, Staphylococcus, Acinetobacter, Streptococcus, and Escherichia were among the identified ARG carriers. Maternal age and body mass index (present and before pregnancy), infant sex, maternal consumption of probiotic yogurt during pregnancy, and lactation might be substantial factors influencing the occurrence of ARG-carrying bacteria and ARG distribution in the infant feces. These results indicate that environmental factors may influence the distribution of ARG-carrying bacteria and ARGs themselves in infants during early life. Providing appropriate recommendations regarding maternal age, body mass index during pregnancy, and use of probiotic products could potentially mitigate the transmission of antibiotic-resistant microbiota and ARGs, thereby diminishing the risk of antibiotic-resistant infections and safeguarding children's health.
