Accurate individual egg-laying detection is crucial for eliminating low-yielding breeder ducks and improving production efficiency. However, existing methods are often expensive and require strict environmental conditions. This study proposes a data processing method based on wearable sensors and joint time-frequency representation (TFR), aimed at accurately identifying egg-laying in ducks.

Division of Child and Adolescent Psychiatry, Department of Psychiatry and Behavioral Sciences, Johns Hopkins University School of Medicine, Baltimore, Maryland, USA.
Objective: This study investigated longitudinal relationships between social media usage and binge eating (BE) in early adolescence and explored potential moderating effects of sex and BMI.
Methods: Data from the Adolescent Brain Cognitive Development (ABCD) Study, including 1940 participants aged 11 to 12 years at Wave 1, were analyzed over three annual waves. Social media addiction (SMA) scores and time spent on social media were calculated from self-report questionnaires.
Vitamin D requirements and relative bioavailability for starter male White Pekin ducks fed either cholecalciferol or 25-hydroxycholecalciferol.

State Key Laboratory of Animal Nutrition and Feeding, Institute of Animal Science, Chinese Academy of Agricultural Sciences, Beijing, 100193, China. Electronic address:
The objectives were to investigate effects of various concentrations of dietary vitamin D (VD) or 25-hydroxycholecalciferol (25-OH-D) on growth performance, VD status, calcium (Ca) metabolism, and tibia mineralization of starter male White Pekin ducks, and dietary requirements and relative bioavailability of these two compounds. One-day-old male White Pekin ducks (n = 624) were assigned to 13 dietary treatments, including 6 added VD concentrations (100, 200, 400, 800, 1200, and 2000 IU/kg), and 2 vitamin D sources (VD and 25-OH-D), plus a negative control (no vitamin D supplementation) for 21 days. Each group had 6 replicate pens of 8 birds per pen.

Article Synopsis
- - The study investigates how the invasive Egyptian goose manages resources between reproduction and immune function compared to native species like the mallard and mute swan, focusing on immune markers and oxidative status.
- - Results indicate that Egyptian geese have lower adaptive immune markers compared to the native species, suggesting a strategy to allocate more resources to reproduction and spreading rather than immune defense.
- - Overall, while the Egyptian goose maintains a generally similar innate immune function to mallards, it shows reduced investment in adaptive immunity, likely allowing it to thrive in new environments without the pressure of native parasites.
Association between insomnia and four domains of health based on an Indigenous Medicine Wheel: Findings from two Saskatchewan First Nation communities.

Objectives: Research has shown that insomnia and chronic diseases can simultaneously impact overall health, including physical, mental, emotional, and spiritual health. This study aims to find the association between insomnia and the four domains of health based on an Indigenous Medicine Wheel and to find the role of multimorbidity as a mediator between this relation among First Nations people.
Methods: We used data (n = 588) from the First Nations Sleep Health Project, a collaboration between two Cree First Nations communities in Saskatchewan and a research team at the University of Saskatchewan.
