Abstract	The Tianyuan 1 skeleton is among the oldest fossil specimens of our species from East Asia. Important in the original assessment of the skeleton as belonging to a modern human was its femoral structure, particularly its well-developed pilasters. Also noteworthy were its large femoral diaphyseal second moments of area, which were interpreted as evidence of a physically demanding lifestyle, and pathological bone growths on the posterior femoral shafts. Here, we build on previous studies of femoral morphology in Tianyuan 1 by analyzing its diaphyseal structure using micro-computed tomography coupled with a novel method of visualizing cortical bone thickness distributions along the shaft with color maps. Additionally, we calculate diaphyseal second moments of area in Tianyuan 1 with and without its pathological bone additions in order to evaluate whether these growths are the cause of its apparently high diaphyseal robusticity. Diaphyseal color maps and second moments of area of Tianyuan 1 femora are compared to those of three recent (Holocene) human comparative samples, as well as samples of Pleistocene humans. The results show that in terms of cortical thickness distribution, Tianyuan 1 femoral diaphyses are strikingly similar to those of recent humans, as well as Pleistocene early modern humans, yet distinct from the diaphyses of Neandertals. This provides additional support for the modern human status of Tianyuan 1. Analyses of second moments of area reveal that Tianyuan 1 is best classified as a Pleistocene early modern human rather than as a member of any of the recent samples when pathological bone additions are included in area moment calculations. Interestingly, however, once pathological growths are virtually removed, Tianyuan 1 cannot be assigned with confidence to any comparative group. This suggests that the relatively high anteroposterior femoral diaphyseal strength mid-distally in Tianyuan 1 is to some degree a product of its pathological condition.

Abstract	We report here on the isotopic analysis of the diet of one of the oldest modern humans found in Eurasia, the Tianyuan 1 early modern human dating to approximately 40,000 calendar years ago from Tianyuan Cave (Tianyuandong) in the Zhoukoudian region of China. Carbon and nitrogen isotope analysis of the human and associated faunal remains indicate a diet high in animal protein, and the high nitrogen isotope values suggest the consumption of freshwater fish. To confirm this inference, we measured the sulfur isotope values of terrestrial and freshwater animals around the Zhoukoudian area and of the Tianyuan 1 human, which also support the interpretation of a substantial portion of the diet from freshwater fish. This analysis provides the direct evidence for the consumption of aquatic resources by early modern humans in China and has implications for early modern human subsistence and demography.

Abstract	Objective: To observe the effect and mechanism of Tianyuan Ketong recipe (TKR) on the pain reaction in formalin induced pain model rats. Methods: The analgesic effect of TKR was evaluated using pain behavior graded scoring, the c-fos gene expression and P substance contents in superficial lamella of spinal cord dorsal horn in model rats were analyzed by means of immunohistochemical analysis and computer image analysis technique. Results: TKR could markedly inhibit the pain reaction in model rats (P < 0.05), and the pain induced elevation of c-fos expression and P substance contents could also be suppressed (P < 0.05). Conclusion: TKR shows definite analgesic effect on formalin induced pain model rats, the reduction of neuron's reaction in spinal cord dorsal horn to afferent noxious stimulation is possibly one of the pathways for its analgesic effect.

Abstract	Background: Marital goals reflect individuals' understanding of the purpose of marriage and could influence the dyadic interactions and satisfaction in intimate relationships. The current study examines how each partner's marital goals and the concordance of marital goals between the partners influence dating couples' relationship satisfaction through dyadic coping. Method: The sample consisted of 200 heterosexual dating couples from Hong Kong. Both partners completed a survey that assessed three types of marital goals, dyadic coping, relationship satisfaction, and other background variables. Path analysis was conducted to estimate the Actor-Partner Interdependence Model (APIM) with each partner's three types of marital goals and marital goal concordance between the two partners as the predictors, each partner's dyadic coping as the mediators, and each partner's relationship satisfaction as the outcomes. Results: Women's dyadic coping significantly mediated the effects of women's companionship goals and marital goal concordance on both partners' marital satisfaction. Meanwhile, men's dyadic coping significantly mediated the effects of men's companionship goals and marital goal concordance on their own relationship satisfaction. Conclusion: The current study offered the first evidence supporting the importance of marital goals, the goal concordance between the partners, and dyadic coping in dating relationships.

Abstract	Introduction: Previous studies have explored the impact of social media use on people's subjective well-being, but there is a lack of discussion on the relationship between social media use, Internet addiction, and subjective well-being, and the research on the influence of digital skills on this relationship is not sufficient. This paper aims to fill these gaps. Based on the flow theory, this paper takes Chinese residents as the research object and uses CGSS 2017 data to analyze the impact of social media use on people's subjective well-being. Methods: Our study used multiple linear regression models for analysis. To test the hypotheses and the moderated mediation model, we adopted PROCESS models with 5000 bias-corrected bootstrap samples and 95% confidence intervals. All analyses were conducted using SPSS 25.0. Results: The empirical analysis shows that social media use has a positive direct effect on subjective well-being, and Internet addiction plays a suppressing role in the relationship between social media use and subjective well-being. In addition, we found that digital skills moderated the positive effect of social media use on Internet addiction and the indirect effect of social media use on subjective well-being through Internet addiction. Discussion: The conclusion of this paper supports our previous hypothesis. Besides, the theoretical contribution, practical significance, and limitations of this study are discussed based on the results of previous studies.

Abstract	Introduction: Problematic internet use among the elderly is an emerging area as previous studies focused more among the young people. Only a few studies focused on problematic internet use at the level of individual characteristics of older adults or on mitigating factors at the level of the older adult's family, ignoring family-level disruptive factors. Objective: The purpose of study is to investigate the relationship between conflict with children and problematic internet use among the elderly, as well as the mediating mechanisms and boundary conditions of the relationship. Methods: The valid sample of study composed of 428 older adults from 39 different villages and communities in central China. Data analyses were conducted by SPSS, MPLUS, and SmartPLS software. To test our hypotheses, we implement several quantitative methods, including confirmatory factor analysis (CFA), correlations analysis, and ordinary least squares (OLS) regression. Also, we employed partial least square structural equation modeling (PLS-SEM) for robustness testing. Results: The results indicated that conflict with children was positively associated with problematic internet use of old people; psychological depression mediated the relationship between conflict with children and old adults' problematic internet use; sociability moderated the effect of conflict with children on psychological depression; and living situation moderated the effect of psychological depression on problematic internet use among the elderly. Conclusion: The current research improved the understanding of the mechanisms that produce problematic internet use among the elderly and helped prevent or reduce problematic internet use in older adults in terms of family support systems and individual ability characteristics.

Abstract	Ferroelectrics and ionic conductors are important functional materials, each supporting a plethora of applications in information and energy technology. The underlying physics governing their functional properties is ionic motion, and yet studies of ferroelectrics and ionic conductors are often considered separate fields. Based on first-principles calculations and deep-learning-assisted large-scale molecular dynamics simulations, we report ferroelectric-switching-promoted oxygen ion transport in HfO_{2}, a wide-band-gap insulator with both ferroelectricity and ionic conductivity. Applying a unidirectional bias can activate multiple switching pathways in ferroelectric HfO_{2}, leading to polar-antipolar phase cycling that appears to contradict classical electrodynamics. This apparent conflict is resolved by the geometric-quantum-phase nature of electric polarization that carries no definite direction. Our molecular dynamics simulations demonstrate bias-driven successive ferroelectric transitions facilitate ultrahigh oxygen ion mobility at moderate temperatures, highlighting the potential of combining ferroelectricity and ionic conductivity for the development of advanced materials and technologies.
