Temperature-dependent behavior of polymer latex in calcium sulfoaluminate cement: critical role of glass transition temperature

Polymer latex modification is highly temperature-sensitive in cement-based systems, yet its governing mechanisms remain unclear, particularly under sub-zero conditions. This study systematically investigates the temperature-dependent behavior of a controlled model polymer‑calcium...

Energy dependence and the differential pass-through of oil price shocks to inflation: evidence from 72 countries

International oil price fluctuations are an important source of external inflation pressure, but their domestic effects vary across economies depending on exposure to imported energy costs. This study examines whether energy dependence systematically explains heterogeneous inflat...

Dual pathways from adversity: CEO childhood famine experience, motivational orientations, and organizational resilience

Organizational resilience is critical for sustained development in turbulent contexts; however, the mechanisms linking chief executive officers’ (CEOs) early-life adversity to organizational resilience and their boundary conditions remain underexplored. Drawing on imprinting and...

Burning characteristics and micro-explosions of free-falling boron-based slurry-fuel droplets
