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 ...

Nonlinear Dynamics of a Passive Walker: Bifurcation and Stability Insights With Spring and Damper Mechanics

International Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT This study explores the nonlinear dynamics associated with a passive dynamic walker (PDW), focusing on the bifurcation and stability insights derived from spring and damper mechanics. PDWs, which rely on gravity for stable locomotion without active control, exhibit a rich spectrum of behaviors, from periodic to chaotic motion.

Primary producers' positions towards bears and bear conservation: Insights for human–bear coexistence

People and Nature, EarlyView.
Abstract We present primary producers' (farmers', livestock breeders', beekeepers') positions towards bears and bear conservation as documented through semi‐structured interviews within the frame of human dimensions actions of LIFE projects implemented between 2015 and 2022 in Greece.

Navigating across individual and deliberative values: A dual Q‐method approach to elicit diverse values in grassland restoration

People and Nature, EarlyView.
Abstract The current ‘UN Decade on Restoration’ calls for collaboration between scientists and practitioners to formulate guidelines for ecosystem restoration, within which transdisciplinary approaches are imperative to rethink the diverse values associated with nature, paving the way for sustainable ecosystem restoration.

Artificial Intelligence as an Add‐On Instrument in Fetal Ultrasound; Sonographers' and Obstetricians' Expectations

Prenatal Diagnosis, EarlyView.
ABSTRACT Objective Artificial intelligence applications (AIA) in fetal ultrasound are rapidly evolving, yet their integration into routine clinical practice remains limited. This study explores the attitudes, expectations and concerns of obstetric sonographers and gynecologists regarding AIA as a diagnostic aid during fetal anomaly scans.
