Ultrasonography Sliding Sign as a Predictor for Intraabdominal Adhesions in Repeated Cesarean Deliveries: Retrospective Cross Sectional Study

Journal of Clinical Ultrasound, EarlyView.
This retrospective cohort study included 350 individuals who underwent cesarean section. Data from 198 participants who met the inclusion criteria were analyzed. The region below ROC curves for the sliding sign was 0.717 (95% CI: 0.645–0.789). The sensitivity was 58.9%, specificity was 84.6%, positive predictive value (PPV) was 81.7%, negative ...

Preparing for Tomorrow's Teamwork: Insights From eSports on How Human Expertise Shapes Training Needs for AI‐Integrated Work

Journal of Organizational Behavior, EarlyView.
ABSTRACT As organizations increasingly adopt human‐AI teams (HATs), understanding how to enhance team performance is paramount. A crucially underexplored area for supporting HATs is training, particularly helping human teammates to work with these inorganic counterparts.

Successive Mechanical Recycling of Poly(lactic Acid) by Injection Molding: Evolution of Molecular, Thermal, and Mechanical Properties

Macromolecular Materials and Engineering, EarlyView.
This study investigated how successive injection molding recycling affects the properties of poly(lactic acid) (PLA). Gel permeation chromatography showed a two‐thirds molar mass reduction after ten reprocessing cycles. Differential scanning calorimetry revealed lower glass transition and cold crystallization temperatures.

Mass Spectrometry Structural Proteomics Enabled by Limited Proteolysis and Cross‐Linking

Mass Spectrometry Reviews, EarlyView.
ABSTRACT The exploration of protein structure and function stands at the forefront of life science and represents an ever‐expanding focus in the development of proteomics. As mass spectrometry (MS) offers readout of protein conformational changes at both the protein and peptide levels, MS‐based structural proteomics is making significant strides in the

Kinetic Compensation of Barrel Launch Under High‐Speed Solid‐Phase Particulate Impacts

International Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT An accurate launch‐dynamics computational method is critical for barrel weapon service life assessment and multiphase physics field refinement. Given the lack of studies on the solid‐phase buildup behavior at the projectile base, this paper provides an improved method for calculating the launching dynamics under high pressure and high speed ...
