Microplastic hotspots mapped across the Southern Ocean reveal areas of potential ecological impact.
Sci Rep
December 2024
British Antarctic Survey, High Cross, Madingley Road, Cambridge, UK.
Marine microplastic is pervasive, polluting the remotest ecosystems including the Southern Ocean. Since this region is already undergoing climatic changes, the additional stress of microplastic pollution on the ecosystem should not be considered in isolation. We identify potential hotspot areas of ecological impact from a spatial overlap analysis of multiple data sets to understand where marine biota are likely to interact with local microplastic emissions (from ship traffic and human populations associated with scientific research and tourism).

Reservoir-operation optimisation is a crucial aspect of water-resource development and sustainable water process management. This study addresses bi-objective optimisation problems by proposing a novel crossover evolution operator, known as the hybrid simulated binary and improved arithmetic crossover (SBAX) operator, based on the simulated binary cross (SBX) and arithmetic crossover operators, and applies it to the Non-dominated Sorting Genetic Algorithms-II (NSGA-II) algorithm to improve the algorithm. In particular, the arithmetic crossover operator can obtain an optimal solution more precisely within the solution space, whereas the SBX operator can explore a broader range of potential high-quality solutions.

Department of Anesthesiology, Qilu Hospital of Shandong University, Jinan, Shangdong, China.
Background: The association between different anthropometric indices, including body mass index (BMI), a body shape index (ABSI), lipid accumulation product (LAP), visceral adiposity index (VAI), waist circumference-triglyceride index (WTI), weight-adjusted waist index (WWI), body roundness index (BRI) and the prevalence of overactive bladder (OAB) is unclear. This investigation aims to explore the association among different anthropometric indices and overactive bladder as well as confounding variables.
Methods: Data were obtained from the USA National Health and Nutrition Examination Survey (NHANES) data set between 2005 and 2018, and 15231 participants were included in the study.
Multidimensional internet use related to cognitive performance in older persons: a nationwide cross-sectional study.
Front Public Health
December 2024
School of Pharmaceutical Economics and Management, Anhui University of Traditional Chinese Medicine, Hefei, China.
Introduction: The internet has been increasingly recognized as a potential driver for enhancing cognitive functioning in older adults; however, the mechanisms underlying this relationship remain insufficiently understood in the literature. This study aimed to investigate the associations between different dimensions of internet use-activity, device, and frequency-and cognitive performance in older adults.
Methods: This cross-sectional study utilized data from the fourth wave of the China Health and Retirement Longitudinal Study (CHARLS), involving a nationally representative sample of 17,676 participants aged 60 years and above.
