Recent years have witnessed notable advancements in medical image segmentation through deep convolutional neural networks. However, a notable limitation lies in the local operation of convolution, which hinders the ability to fully exploit global semantic information. To overcome the challenges prevalent in medical image segmentation, the feature ensemble network with multi‐scale atrous transformer is proposed. At the core of the approach lies the multi‐scale contextual integration module, which is based on the multi‐scale atrous transformer and facilitates contextual integration of multi‐level features. To extract discriminative fine‐grained features of the target region, a hybrid attention mechanism that synergistically combines spatial and channel attention, thereby sharpening the model's focus on crucial target information within high‐level features, is incorporated. Additionally, the channel‐aware feature reconstruction module is introduced as an innovative component engineered to tackle feature similarity issues across different categories. This module performs feature reconstruction based on channel perception, effectively widening the feature gap between categories and enhancing the segmentation capability. It is worth mentioning that our approach surpasses the state‐of‐the‐art method using three benchmark datasets in medical image segmentation. [ABSTRACT FROM AUTHOR]

In recent years, "cultural tightness–looseness" refers to the strength of social norms and tolerance for deviant behaviors perceived by individuals in society, and team cultural tightness applied at the organizational level represents the strength of team norms. According to the cultural tightness–looseness theory, this study explores the influence of team cultural tightness on employee creative behavior, as well as the moderating role of transformational leadership and the mediating role of work engagement. A questionnaire method was used to survey five enterprise organizations in China through three stages, and 288 paired questionnaires were finally obtained from leaders and employees. The results found that team cultural tightness has a significant negative effect on employee creative behavior through the mediating effect of work engagement. In other words, the more the team culture in the workplace tends to be loose, the more it stimulates employee work engagement, which in turn promotes employee creative behavior. In addition, transformational leadership played a significant positive moderating role in the model. Under the influence of transformational leadership style, the negative impact of team cultural tightness on employee work engagement and creative behavior can be mitigated. The study enriches the understanding of the influence and action mechanism of the cultural tightness–looseness theory on employee creative behavior. In future research, the action mechanism of team cultural tightness interacting with different leadership styles to influence employee creative behavior will be explored more deeply.

It is well-known that in neutral and acidic aqueous electrolytes, MoS2 monolayers can store charges by adsorption of cations on to the electrode-electrolyte interface as its analog of graphene. Restricted by its low conductivity and the charge storage mechanism, the electrochemical performance of MoS2 monolayer supercapacitor electrode is not satisfactory. It is reported here that water bilayers absorbed on MoS2 monolayers can be involved in charge storage. One proton of each absorbed water molecule can intercalate/de-intercalate the water bilayers during charging/discharging in the alkaline aqueous electrolyte. For two water molecules are present for every Mo atom, the water bilayers can endow MoS2 monolayers an ultrahigh specific capacitance. In this paper, 1T phase MoS2 nanosheets with three monolayers were synthesized by hydrothermal reaction. It presents a specific capacitance of 1120 F g−1 at a current density of 0.5 A g−1 in KOH. As it is assembled with active carbon into a hybrid supercapacitor, the device has an energy density of 31.64 Wh kg−1 at a power density of 425 W kg−1, and gets a specific capacitance retention of 95.4% after 10,000 cycles at 2 A g−1.

Background: COVID-19, as a significant public health issue, has had a major impact on the mental health of people worldwide. Research shows a significant positive correlation between individuals' risk perception levels and negative emotions during the outbreak of COVID-19. However, some studies also suggest that the relationship between the two is not significant. Therefore, we will conduct a meta-analysis to explore the relationship between risk perception and negative emotions from cultural, temporal, and individual psychological perspectives., Methods: Searches were conducted in the Web of Science, Pub Med, Google Scholar, PsycINFO, Scopus, and China National Knowledge Infrastructure databases, focusing on publications from January 2020 onwards, specifically targeting studies examining the relationship between risk perception and negative emotion during COVID-19., Results: A total of 58 papers with 85 effect sizes were meta-analyzed using Comprehensive Meta-Analysis 3.0 software, with a combined sample of 83,948 individuals. Risk perception of COVID-19 showed a moderate positive correlation with negative emotions ( r  = 0.211, 95%CI [0.18, 0.24]). There was no moderating effect of tight-loose cultures on the relationship between risk perception of COVID-19 and negative emotions. However, the epidemic period, gender ratio, and measurement methods did have moderating effects on the relationship between risk perception of COVID-19 and negative emotions., Conclusion: In future research, we can further develop theories related to the risk perception of COVID-19 and negative emotions, and based on these, formulate interventions to promote people's mental health., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2024 Zhou, Shi, Song, Li and Zhou.)

As supercapacitor electrode materials, their structures, including specific surface area, instability, and interconnection, determine the electrochemical performances (specific capacitance, cycle stability, and rate performance). In this study, 1T-MoS 2 nanosheets were self-assembled into nanoflowers via a one-pot facile hydrothermal reaction. The nanoflowers retain the excellent electrical conductive performance and the feature of inherent high specific surface area of the nanosheets. For the sheets are interconnected to each other in flower structure, the structure is more stable and the charges are more easily transferred. Thus, compared to the nanosheet electrode, the nanoflower electrode shows the remarkable advantage when used as the electrode of the energy-storage device, whether it is 1T phase or 2H phase in KCl or in KOH. When measured at 0.5 A g -1 in KOH electrolyte, the MoS 2 nanoflower electrode exhibits a high specific capacitance of 1120 F g -1 . At the same time, when cycling 2000 times at a current density of 10 A g -1 , the capacitance retention ratio can reach up to 96%., Competing Interests: The authors declare no competing financial interest., (Copyright © 2019 American Chemical Society.)

Objective: To study the effect of the nutritional education and dietary intervention on nutritional status and bone mineral density (BMD) of middle-aged and senile patients with osteoporosis., Methods: Ninty middle-aged and senile osteoporosis patients were enrolled. They were randomly divided into two groups (intervention and control group) with 45 cases each. The control group was received conventional therapy and the intervention group added with nutritional education and dietary intervention for six months on the basis of conventional therapy. The methods of education and intervention included seminars, brochures distribution, dietary survey and individual guidance. The nutritional status and BMD were analyzed at the beginning and the end of the intervention respectively., Results: After the intervention, the ratios of subjects whose intake of grain, vegetables, fruits, eggs, milk and beans in line with recommended intake of the intervention group were higher than those of the control group (P < 0.05). After the intervention, frequencies of coarse grain, dairy, beans and seafood consumption of the intervention group were higher than those of the control group (P < 0.05). After the intervention, the daily intakes of protein, VA, VC, calcium, zinc, magnesium, dietary fiber of the intervention group were significantly superior to the control group (P < 0.05). BMDs of lumbar spine and femoral neck in the intervention group were significantly higher than those in the control group (P < 0.05)., Conclusion: The nutritional education and dietary intervention could promote middle-aged and senile patients' reasonable diet, improve their nutritional status, enhance bone mineral density and improve the effect of conventional therapy for osteoporosis.

Objective: To study the influence factors of vitamin B1, vitamin B2 losses in vegetables during cooking., Methods: 12 types of fresh vegetables were selected and cooked by different cooking process, including roast, braise, fry, steam, scald and salt curing. vitamin B1 and vitaminB2 contents in raw and cooked samples were analysed respectively by GB/T 5009.84--2003 and GB/T 5009.85--2003 fluorometry. At the same time, weights of vegetables before and after cooking were recorded. Then CY and RF were calculated., Results: The results showed that the retention rate in leguminous vegetables was 66%-75% for vitamin B1 and 85%-190% for vitamin B. Scalding could cause bigger loss of vitamin B1 in leafy vegetables and root vegetables, RF was about 50. The values of vitamin B2 RF in leafy vegetables for roasting was bettering than for scalding. For vitamin B2, the retention rate in root and cucurbitaceous vegetables was about 77-79., Conclusion: Vitamin B1 and vitamin B2 retention factors of roasting and steaming are more than that of frying and scalding. Temperature, time and variety of vegetable are the important influence factors of vitamin retention factors.
