Abstract	Deepfake is a type of image and video face manipulation methods which could cause security and society threats. Although some related databases and detection models have been proposed for detecting face forgery media, achieving a generalizable detector for both known and unknown manipulations remains challenging. In this study, a novel deepfake detection model with high generalizability is proposed to tackle this issue. We employ supervised contrastive learning to enhance the generalizability to unknown manipulations and datasets. In addition, we design a cross-modality data augmentation method by combining SRM and RGB features to extract detection clues comprehensively. Furthermore, we propose a multi-scale feature enhancement module to enhance textural and semantic information. Extensive experiments have demonstrated that our method improves model generalization in both intra- and cross- dataset scenarios.

Abstract	IntroductionCOVID-related work changes have seriously disrupted employees’ familiar routines and hampered their lives and work. Although this topic has drawn rising attention, to our knowledge, limited studies have investigated the impact of COVID-related work changes on employees’ mentality and behavior. In this paper, we developed a moderated mediation model based on ego depletion theory to test how and when COVID-related work changes impact employees’ mental health, interpersonal conflict, and aggression behavior.MethodsWe collected 536 valid participants by conducting a questionnaire survey in a large Chinese manufacturing company, and tested our proposed theoretical model and hypotheses using SPSS 26.0 and Mplus 8.1.ResultsThe empirical results showed that COVID-related work changes would harm employees’ mental health and boost their interpersonal conflict and aggression via increasing their ego depletion. Moreover, trait resilience has an intervention in the relationship between COVID-related work changes and employees’ ego depletion, which weakens the indirect impact of COVID-related work changes on mental health, interpersonal conflict, and aggression.DiscussionThese findings suggest that although COVID-related work changes were inevitable, managers should take measures to improve the employees’ mental status and avoid conflicts promptly while taking steps to keep organizations on track.

Abstract	High consumption of ultra-processed foods (UPF) increases the risks of non-communicable diseases and all-cause mortality in adulthood, and the risk of early childhood caries. Limited evidence about factors influencing children’s consumption of UPF exists. This study was conducted to assess the prevalence of UPF consumption among children less than three years of age, and identify its associations with caregivers’ emotional and instrumental feeding, and children’s emotional eating. A cross-sectional study was conducted in Shijiazhuang, Hebei Province, China. Caregivers caring for children aged 6–36 months ( n = 408) were recruited. Caregivers’ emotional and instrumental feeding practices and children’s emotional eating were assessed by the Parents’ Feeding Practices Scale for Infant and Young Child and Children’s Eating Behaviour Questionnaire, respectively. Children’s UPF consumption was assessed by a validated Food Frequency Questionnaire. Of the children, 86.8% consumed UPF. The highest percentage of UPF consumed was pastries (63.5%), followed by solid or semi-solid dairy products (58.8%), and reconstituted meat products (56.4%). Caregivers’ emotional and instrumental feeding was positively associated with children’s consumption of UPF (OR = 1.59, 95%CI: 1.01, 2.49), a higher frequency of UPF consumption weekly (OR = 1.80, 95%CI: 1.35, 2.39), and a larger amount of UPF consumption weekly (OR = 1.85, 95% CI: 1.38, 2.49). Children’s higher frequency of emotional undereating was associated with their UPF consumption (OR = 1.61, 95%CI: 1.07, 2.42) and a higher frequency of UPF consumption weekly (OR = 1.33, 95%CI: 1.03, 1.73). Children’s emotional undereating significantly mediated the associations between caregivers’ emotional and instrumental feeding and children’s consumption of reconstituted meat products. Caregivers should be educated to avoid emotional and instrumental feeding practices, and cultivate children’s good eating habits to improve children’s diet quality.

Abstract	Coverless image steganography (CIS) has attracted significant attention because it can fundamentally resist steganalysis tools. Available CIS schemes are mainly divided into synthesis-based and mapping-based schemes. Compared with the former, mapping-based methods ensure lossless information extraction and stronger attack robustness. However, these methods still face the challenges of incomplete secret information mapping, trade-off between robustness and distinguishability of mapping features, and demand for huge numbers of mapping images. To tackle these issues, a novel robust coverless steganography using limited mapping images is proposed in this paper. In our scheme, we extract ring statistics to ensure both the distinguishability and robustness of mapping features. Moreover, different from conventional CIS schemes, we further design a chaotic system for scrambling image features to map secret information. Using this system, a single image is mapped to multiple secret information instances using different scrambled features, which reduces the demand on the numbers of images and avoids incomplete mapping. Furthermore, the scrambled features also enhance the security of secret information. Experimental results demonstrate that our scheme has superior performance in terms of distinguishability and robustness against geometrical attacks, the required number of mapping images, and mapping completeness.

Abstract	New surface coordination photocatalytic systems that are inspired by natural photosynthesis have significant potential to boost fuel denitrification. Despite this, the direct synthesis of efficient surface coordination photocatalysts remains a major challenge. Herein, it is verified that a coordination photocatalyst can be constructed by coupling Pd and CTAB-modified ZnIn 2 S 4 semiconductors. The optimized Pd/ZnIn 2 S 4 showed a superior degradation rate of 81% for fuel denitrification within 240 min, which was 2.25 times higher than that of ZnIn 2 S 4 . From the in situ FTIR and XPS spectra of 1% Pd/ZnIn 2 S 4 before and after pyridine adsorption, we find that pyridine can be selectively adsorbed and form Zn⋅⋅⋅C-N or In⋅⋅⋅C-N on the surface of Pd/ZnIn 2 S 4 . Meanwhile, the superior electrical conductivity of Pd can be combined with ZnIn 2 S 4 to promote photocatalytic denitrification. This work also explains the surface/interface coordination effect of metal/nanosheets at the molecular level, playing an important role in photocatalytic fuel denitrification.

Abstract	Purpose To discover the biological function and potential mechanism of LINC01936 in the development of lung squamous cell carcinoma (LUSC). Methods Transcriptome data of LUSC from The Cancer Genome Atlas (TCGA) and Gene Expression Omnibus (GEO) databases were used to analyze the differentially expressed lncRNAs in LUSC and normal tissues by R “DEseq2”, “edgeR” and “limma” packages. The subcellular localization of LINC01936 was predicted by lncLocator. Cell proliferation and apoptosis were measured by CCK-8, MTT assay and Hoechst fluorescence staining. The migration and invasion were detected by Transwell assay. The function and pathway enrichment analysis were performed by Gene Ontology (GO) terms, Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analysis and gene set variation analysis (GSVA). The downstream targets of LINC01936 were predicted using RNA-Protein Interaction Prediction (RPISeq) program. The effect of LINC01936 on tumor immune infiltration was analyzed using Pearson Correlation Analysis using R “ggpubr” package. Results Based on the gene expression data of LUSC from TCGA database, 1,603, 1,702 and 529 upregulated and 536, 436 and 630 downregulated lncRNAs were obtained by DEseq2, edgeR and limma programs, respectively. For GSE88862 dataset, we acquired 341 differentially expressed lncRNAs (206 upregulated and 135 downregulated). Venn plot for the intersection of above differential expressed lncRNAs showed that there were 29 upregulated and 23 downregulated genes. LINC01936 was one of downregulated lncRNAs in LUSC tissues. The biological analysis showed that the overexpression of LINC01936 significantly reduced proliferation, migration and invasion of LUSC cells, and promoted cell apoptosis. The knockdown of LINC01936 promoted cell proliferation and metastasis. Pathway and GSVA analysis indicated that LINC01936 might participated in DNA repair, complement, cell adhesion and EMT, etc. LINC01936 was predicted to interact with TCF21, AOC3, RASL12, MEOX2 or HSPB7, which are involved in EMT and ...

Abstract	Abstract Background Coronavirus Disease 2019 (COVID-19) has spread worldwide. The safety of breastfeeding of SARS-CoV-2-positive women has not yet reached a consensus among the scientific community, healthcare providers, experts in lactation care, health organizations and governments. This study was conducted to summarize the latest evidence about the safety of breastfeeding among suspected/confirmed infected mothers and to summarize the recommendations on breastfeeding during COVID-19 from different organizations. Methods A comprehensive literature review of publications about the safety of breastfeeding among SARS-CoV-2-infected mothers was conducted. Scientific databases were searched up to 26 May 2021. The evidence was summarized into five perspectives according to a framework proposed by van de Perre et al. with certain modifications. Moreover, websites of different health organizations were visited to gather the recommendations for breastfeeding. Results The current evidence demonstrated that the majority of infants breastfed by infected mothers were negative for SARS-CoV-2. Breast milk samples from suspected/infected mothers mainly demonstrated negative results in SARS-CoV-2 viral tests. There was insufficient evidence proving the infectivity of breast milk from infected mothers. Recent studies found other transmission modalities (e.g., milk containers, skin) associated with breastfeeding. Specific antibodies in the breast milk of infected mothers were also found, implying protective effects for their breastfed children. According to van de Perre’s criteria, the breast milk of infected mothers was unlikely to transmit SARS-CoV-2. Owing to the low quality of the current evidence, studies with a more robust design are needed to strengthen the conclusion regarding the safety of breastfeeding. Further studies to follow up the health status of infants who were directly breastfed by their suspected/infected mothers, to collect breast milk samples at multiple time points for viral tests and to examine specific ...

Abstract	International students may have difficulties in dietary acculturation. This study aimed to evaluate the knowledge, attitude and practices (KAP) of diet and health during the acculturation of international students. A cross-sectional survey was conducted among a convenience sample of 473 international students in Dublin. Knowledge, attitude and practices towards diet and health were evaluated by a questionnaire with open- and closed-ended questions. It was found that 45.3% of participants had a broad concept of a healthy diet, while few knew its specific contents. Furthermore, 75.3% of participants could explain the term functional food, and among them, 62.1% knew the appropriate definition of functional food. Participants who perceived their health very good and excellent were more likely to believe that their health status was determined by their own control. The consumption rate of functional food varied among regions and South and Central America students had the highest usage rate (44.5%) and Asian students had the highest daily usage rate (52.7%). Participants who were younger, single, from African and South and Central American countries, or who were in Ireland for less than one year were more likely to report dietary change after immigration. In conclusion, insufficient knowledge and self-perception towards diet and health as well as unhealthily dietary changes exist among international students living in Dublin.

Abstract	This study was conducted to explore the associations between maternal feeding practices, mealtime emotions, as well as maternal food neophobia and toddlers’ food neophobia in Ireland. A follow-up to the Technological University Dublin (DIT)-Coombe Hospital birth cohort was conducted. Mothers in the original cohort were invited to the present study by telephone calls. Postal questionnaires with stamped addressed envelopes were distributed to those who agreed to participate in the study. Toddler food neophobia was assessed by the modified version of the Child Food Neophobia Scale (CFNS). There were 205 participants included in this study, with a median score of child food neophobia of 12. A higher degree of child food neophobia (score > 12) was positively associated with the maternal practice of coaxing the children to eat at refusal (OR (Odds Ratio) = 2.279, 95% CI: 1.048–4.955), unpleasant emotions at mealtime (e.g., stressful or hectic for mothers, or tearful for children) (OR ranged between 1.618 and 1.952), and mothers’ own degree of food neophobia (OR = 1.036, 95% CI: 1.001–1.072). Mothers who were not worried when confronted with child’s food refusal was negatively associated with toddlers’ food neophobia (OR = 0.251, 95% CI: 0.114–0.556). This study suggests the maternal practices of responsive feeding, being calm and patient with the toddlers, and creating a positive atmosphere at mealtime.
