Observer-Based Optimal Backstepping Security Control for Nonlinear Systems Using Reinforcement Learning Strategy.

This article considers an observer-based optimal backstepping security control for nonlinear systems using reinforcement learning (RL) strategy. The main challenge faced is the design of optimal contoller under the deception attacks. Therefore, this article introduces an improved security RL algorithm based on neural network technology under the design framework of critic-actor to resist attacks and optimize the entire system.

Eating Styles Profiles and Correlates in Chinese Postpartum Women: A Latent Profile Analysis.

Postpartum women present a high risk of disordered eating behaviors, but the heterogeneity between groups was not identified. This cross-sectional study aimed to identify eating styles profiles in postpartum women and explore the correlates based on demographic characteristics and psychosocial factors. Questionnaires were administered to 507 Chinese postpartum women.

Changes in fertility intention among married Chinese couples with two children during COVID-19: a cross-sectional study.

Background: A three-child policy was implemented in China to stimulate a rise in fertility levels and coincided with the COVID-19 pandemic. Data suggested that COVID-19 has a negative impact on fertility intention.

Aim: To describe married couples' changes in intention to have a third child during the COVID-19 pandemic and determine factors associated with altered intentions.

Trust, discrimination and preference for shared decision-making in adolescents diagnosed with depression: Implications from Chinese mental health professionals.

Background: While evidence suggests that the attitudes of healthcare providers toward medical decision-making in adolescents diagnosed with depression merit exploration, research on their preferences for Shared Decision-Making (SDM) and the factors affecting these preferences remains limited.

Objective: To investigate Chinese mental health professionals' (MHPs) preferences for SDM in adolescents with depression and identify the relationships between their preference for SDM and trust and discrimination.

Methods: A cross-sectional design was used in this study.

Shared decision-making in the treatment of adolescents diagnosed with depression: A cross-sectional survey of mental health professionals in China.

Unlabelled: WHAT IS ALREADY KNOWN?: SDM improves clinical outcomes by increasing attendance and treatment adherence in adolescents diagnosed with depression. SDM could reduce treatment disagreements and enhance consumers' and their families' satisfaction with mental healthcare services. Healthcare professionals are a critical part of SDM.

Determining the core competencies for international postgraduate nursing students in internship programs: A delphi study.

Aim: To determine the core competencies of clinical internships for international postgraduate nursing students undertaking a two-year professional program in China.

Background: Clinical internship is an important part of nursing education and is the cornerstone for the future training of nursing professionals. However, in terms of providing a basis for the training and assessment of international postgraduate nursing students undertaking a two-year professional program in China, their core competencies of clinical internships have not yet been sufficiently determined.

A novel RRGW derived peptide is a promising inhibitor of BoNT/A.

Clostridium botulinum neurotoxin type A (BoNT/A) is one of the most potent biotoxins ever known. Its entry into neurons could block vesicle exocytosis to abolish the release of neurotransmitters from nerve terminals, thus leading to muscle paralysis. Although there are so many peptides, antibodies and chemical compounds claimed to have anti-toxin activity, no drug is available in the clinical application except equine antitoxin serum.

Nutritional Status and Sarcopenia in Nursing Home Residents: A Cross-Sectional Study.

Objective: This study aimed to assess the nutritional status and sarcopenia in older people living in nursing homes.

Methods: This cross-sectional study enrolled 386 older adults in nursing homes in Hunan Province, China. Assessments included the Mini Nutritional Assessment Short Form for nutrition risk, Dietary Diversity Score for dietary diversity and Mini Mental State Examination for cognitive status.

Fertility Intention to Have a Third Child in China following the Three-Child Policy: A Cross-Sectional Study.

China's three-child policy was implemented in May 2021 to stimulate a rise in fertility levels. However, few previous studies have explored fertility intentions to have a third child and have only focused on childless or one-child populations, resulting in a gap in findings between fertility intention and fertility behavior. Thus, we conducted a nationwide cross-sectional study on 1308 participants with two children.

Medical decision-making for adolescents with depression: A bibliometric study and visualization analysis via CiteSpace.

This study focussed on evaluating the status of recent research on medical decision-making for adolescents with depression and identifying research hotspots and frontiers via CiteSpace. We extracted studies that were concerned with medical decision-making for adolescents with depression from the Web of Science Core Collection (WoSCC), covering the period from 1 January 1999 to 20 September 2022. We used CiteSpace to generate online maps of worldwide cooperation among countries, institutions, and authors.

Facilitators and barriers of African postgraduate nursing students' adaptation to internship: A qualitative study.

Background: Clinical internship is a focused and supervised practice where nursing students have opportunities to master clinical skills and better adapt to the real working environment, promoting the formation of professional practice quality. However, for African postgraduate nursing students who had an internship in China, the factors affecting their adaptation to the internship have not yet been sufficiently explored.

Objective: To explore the facilitators and barriers of African postgraduate nursing students' adaptation to an internship.

Realgar transforming solution-induced differentiation of NB4 cell by the degradation of PML/RARα partially through the ubiquitin-proteasome pathway.

PML/retinoic acid receptor alpha (RARα), as a hallmark of acute promyeloid leukemia (APL), is directly related to the outcome of clinical APL remedy. It is reported that arsenicals can effectively degrade PML/RARα, such as arsenic trioxide and realgar. However, the high toxicity or insolubility have hampered their clinical applications.

Trajectory tracking control of omnidirectional wheeled mobile manipulators: robust neural network-based sliding mode approach.

This paper addresses the robust trajectory tracking problem for a redundantly actuated omnidirectional mobile manipulator in the presence of uncertainties and disturbances. The development of control algorithms is based on sliding mode control (SMC) technique. First, a dynamic model is derived based on the practical omnidirectional mobile manipulator system.
