Article Synopsis
  • Researchers are developing artificial compound eyes (CE) modeled after arthropods to improve imaging technology, but current designs have issues with defocusing when used with standard CMOS cameras.
  • A new compact camera inspired by South American shrimps utilizes a deep learning method to achieve clear wide-field imaging without complex hardware, significantly simplifying its design.
  • The innovative camera, weighing only 5.4g and measuring 3 x 3 cm, shows superior resolution and 3D trajectory tracking, making it suitable for applications in nano-optics, medical endoscopy, and robotics.

Background: This longitudinal study investigated the temporal stability of social axioms, which are generalised social beliefs, and tested their prospective effects on individuals' flourishing, among students, as well as the extent to which they can be potentially mediated by perceived sense of belonging at school.

Methods: Participants were 195 Chinese university students, who voluntarily completed a questionnaire measuring social axioms (at baseline, 1-year follow-up, and 2-year follow-up studies), school belonging (at 1-year follow-up study), and flourishing (at baseline and 2-year follow-up studies).

Despite the increasing research attention being paid to gaming disorder globally, a screening tool developed specifically for the Chinese population is still lacking. This study aims to address this gap by constructing a screening tool to assess Internet gaming disorder (IGD) symptomology, defined by the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5), among Chinese gamers. Based on expert interviews and consultations, a focus group of gamers, a background literature review, and the IGD criteria proposed by the DSM-5, we developed the Chinese Internet Gaming Disorder Checklist (C-IGDC).

This one-year longitudinal study examined trait emotional intelligence as a predictor of Internet gaming disorder (IGD). To date, only cross-sectional research has been conducted to test the protective effects of emotional intelligence against IGD tendency. Based on the Interaction of Person-Affect-Cognition-Execution (I-PACE) model, this study aimed to address the research gap by examining not only the direct effects of trait emotional intelligence, but also its indirect effects (via depressive symptoms and coping flexibility) on IGD, with both a cross-sectional and longitudinal design.

Direct-acting antivirals (DAAs) not only rapidly inhibited hepatitis C virus (HCV) replication but also modulated innate and adaptive immune response in chronic hepatitis C patients. However, the regulatory activity of DAAs to Toll-like receptor 2 (TLR2) stimulation on CD4CD25CD127 regulatory T cells (Tregs) and T helper (Th) 17 cells was not completely understood. In the present study, a total of 23 patients with chronic HCV genotype 1b infection were enrolled, and blood samples were collected at baseline (treatment naive), end of therapy (EOT), and 12 weeks after EOT (SVR12) with daclatasvir plus asunaprevir therapy.
