School Science and Mathematics, EarlyView.ABSTRACT Much of the work in STEM camps tends to be science‐driven with little attention given to mathematics. Guided by a mixed methods embedded research design using data from observations, questionnaires, and a group interview, we investigate if a camp that explicitly integrates mathematics had a positive impact on middle school students' STEM ...

The effect of pre‐exercise hyperventilation on repeated high‐intensity inclined sprint performance
Experimental Physiology, EarlyView.Abstract High‐intensity exercise induces systemic acidosis, which contributes to muscular performance decline. Controlled pre‐exercise hyperventilation has been proposed as a non‐invasive intervention to induce respiratory alkalosis and counteract acidosis‐related acute fatigue.

Macroeconomic Expectations in a War
Scottish Journal of Political Economy, Volume 73, Issue 3, July 2026.ABSTRACT Using short‐ and long‐term macroeconomic forecasts, we estimate the projected cost of the Russian full‐scale invasion of Ukraine for countries in Eastern Europe, the Caucasus, and Central Asia. Shortly after the invasion, the projected cumulative cost over 6 years stood at $2.44 trillion for the region.

Modeling Water Availability during a Blackout under Consideration of Uncertain Demand Response
Engineering ProceedingsWater distribution systems (WDSs) need electric power supply to operate their pumps. Long-lasting power outages (blackouts) can disrupt the availability of water for citizens. If the water supply is limited by constrained pumping capacities caused by the
