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.

Initial Evidence for Self-Organized Criticality in Electric Power System Blackouts [PDF]

, 2000
We examine correlations in a time series of electric power system blackout sizes using scaled window variance analysis and R/S statistics. The data shows some evidence of long time correlations and has Hurst exponent near 0.7.

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.

Blackouts: a sociology of electrical power failure

, 2013
Electricity fuels our existence. It powers water purification, waste, food, transportation and communication systems. Modern social life is impossible to imagine without it. This article looks at what happens when the power goes off.

Alcohol-induced fragmentary blackouts : associated memory processes and neural correlates

, 2010
textAlcohol-induced blackouts, or periods of anterograde amnesia without loss of consciousness, were a diagnostic indicator in Jellinek’s (1952) theory of alcoholism and have been correlated with alcohol use problems (Campbell & Hodgins, 1993 ...

Sub‐MeV Electron Precipitation Driven by EMIC Waves: New Insights From CIRBE/REPTile‐2 Measurements

Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract Electromagnetic ion cyclotron (EMIC) waves are recognized as a key driver of relativistic (>1 MeV) electron loss in Earth's magnetosphere. Growing evidence also suggests that EMIC wave can efficiently scatter sub‐MeV electrons, although the precise energy range and the underlying physical mechanisms remain debated.

Defense Algorithm Based on Reinforcement Learning and Digital Twin for Distribution Protection Devices Adversarial Samples

Engineering Reports, Volume 8, Issue 6, June 2026.
Power system protection devices are vulnerable to adversarial samples. We propose a digital twin and reinforcement learning framework. It trains a virtual model within safe operational boundaries, reducing the false operation rate to below 3.5%. The model's inference delay is under 10 ms, meeting real‐time protection requirements.

Initial experience with a rapid access blackouts triage clinic

, 2011
Transient loss of consciousness (T-LOC), or blackout, is common in acute medicine. Clinical skills are not done well, with at least 74,000 patients misdiagnosed and mistreated for epilepsy in England alone.
