High-value organic solvent recovery and reuse in perovskite solar cell manufacturing.

Recycling high-value organic solvents is crucial but challenging in various industries. For example, the perovskite solar cell (PSC), a rising star of photovoltaic industry, calls for proper management of solvents like ,-dimethylformamide (DMF). Traditional solvent recovery methods are often less effective, costly, and energy-intensive.

A novel approach to palm vein image segmentation combining multi-scale convolution and swin-transformer networks.

This paper proposes a non-contact palm vein image segmentation model that integrates multiscale convolution and Swin-Transformer. Based on an enhanced U-Net architecture, the downsampling path employs a multiscale convolution module to extract hierarchical features, while the upsampling path captures global vein distribution through a sliding window attention mechanism. A feature fusion module suppresses background interference by integrating cross-layer information.

Translation, Cross-Cultural Adaptation, and Psychometric Validation of the Health Information Technology Usability Evaluation Scale in China: Instrument Validation Study.

Background: The dramatic growth of digital health apps highlights an urgent need for rigorous usability evaluation tools. While the Health Information Technology Usability Evaluation Scale (Health-ITUES) has gained validation, a Chinese version has not yet been developed and validated.

Objective: This study aimed to translate and culturally adapt the Health-ITUES into Chinese, customize it for both service consumers and professional health care providers, and evaluate its reliability and validity in the Chinese context.

Development and usability testing of an integrated geriatric care model (SMART system) to promote integrated home-based geriatric care.

Background: Although integrated care has been proposed as a promising approach to the challenges of fragmented geriatric care, a universally accepted implementation framework for integrated care for older adults living at home remains elusive. This study aimed to address the gap by developing an integrated geriatric care model (SMART system) using a knowledge-based clinical decision support system (CDSS) architecture inspired by the principle of neural reflex and evaluate the usability of the SMART system.

Methods: The development of our SMART system was guided by the knowledge-based Clinical Decision Support System architecture and the principle of neural reflexes, which included 5 phases: (1) functional design; (2) architecture and database design; (3) security measures design; (4) user interface and visualization design; (5) prototypes development and iteratively testing.

Progress in the Application of Multifunctional Composite Hydrogels in Promoting Tissue Repair.

Tissue repair is an extremely complex process, and effectively promoting tissue regeneration remains a significant clinical challenge. Hydrogel materials, which exhibit physical properties closely resembling those of living tissues, including high water content, oxygen permeability, and softness, have the potential to revolutionize the field of tissue repair. However, the presence of various complex conditions, such as infection, ischemia, and hypoxia in tissue defects, means that hydrogels with simple structures and functions are often insufficient to meet the diverse needs of tissue repair.

The relationship between psychological capital, burnout and perceived stress in junior nurses: a latent profile analysis.

Background: Psychological capital, an intrinsic personal asset, enhances junior nurses' ability to navigate transition and sustain superior job performance. This study aimed to classify junior nurses into distinct psychological capital profiles and examine their associations with burnout and perceived stress levels.

Methods: A cross-sectional study involving 480 junior nurses from three hospitals in Beijing assessed psychological capital, stress, and burnout using e-questionnaires, from July 2021 to August 2022.

Burnout among Junior Nurses: The Roles of Demographic and Workplace Relationship Factors, Psychological Flexibility, and Perceived Stress.

Background: Burnout is a common psychological syndrome among nurses, especially in the first few years of working. However, limited studies have evaluated the factors related to burnout among junior nurses.

Aims: To investigate the levels of psychological flexibility, stress, and burnout among junior nurses and examine the role of demographic and workplace relationship factors, psychological flexibility, and perceived stress on burnout among junior nurses.

Laparoscopic radical resection for situs inversus totalis with colonic splenic flexure carcinoma: A case report.

Background: Situs inversus totalis (SIT) is a rare group of congenital developmental malformations in the clinical setting, with all organs in the chest and abdomen existing in a mirror image reversal of their normal positions. Few reports have described laparoscopic surgery for colorectal cancer in patients with SIT, and it is considered difficult even for an experienced surgeon because of the mirror positioning. We present a case report of laparoscopic radical resection of a colonic splenic flexure carcinoma in a patient with SIT.

Risk Analysis of Positive PD-L1 Expression and Clinicopathological Features and Survival Prognosis in Patients with Colorectal Cancer: Systematic Review and Meta-Analysis.

In order to explore the significance of PD-L1 expression in the prognosis and clinicopathological characteristics of colorectal cancer (CRC), the PubMed, Embase, Web of Science, Cochrane Library, CNKI, and multisquare databases are systematically searched for the relevant relationship between PD-L1 expression and CRC prognosis. The search time is completed until June 2021. Literature is filtered and data extracted by inclusion exclusion criteria, and Meta-analysis is performed with Stata SE12.
