Elevated carotid body tonic activity contributes to ventilatory acclimatization and de‐acclimatization to high altitude at rest and during exercise

The Journal of Physiology, EarlyView.
Abstract figure legend Participants spent 13 days at high altitude (3800 m), where the reduced inspired oxygen pressure (↓PiO2$ \downarrow {P_{{\mathrm{i}}{{\mathrm{O}}_2}}}$) which elicited ventilatory acclimatization and increased inhibition of ventilation by transient hyperoxia (ΔV̇E$\Delta {\dot V_{\mathrm{E}}}$).

Reduced cardiovascular mortality at moderate altitude: a putative role of physical activity and body mass

The Journal of Physiology, EarlyView.
Abstract figure legend Benefits of performing physical exercise at moderate altitude. At moderate altitude, increased resting metabolic rate and physical exertion promote physical fitness and exercise tolerance, whereas hypoxia suppresses appetite and elicits adaptations that increase tissue O2 delivery while augmenting O2‐independent ATP production ...

Proper account of auto-correlations improves decoding performances of state-space (semi) Markov models

Peer Community Journal
State-space models are widely used in ecology to infer hidden behaviors. This study develops an extensive numerical simulation-estimation experiment to evaluate the state decoding accuracy of four simple state-space models.

Mechanisms reducing parasympathetic activity in chronic hypoxia

The Journal of Physiology, EarlyView.
Abstract figure legend Parasympathetic activity is reduced in chronic hypoxia, but the underlying mechanism(s) are unclear. Using β‐adrenergic blockade to isolate parasympathetic control of heart rate at sea level and after 9‐12 days at high altitude, we investigated whether (i) chemoreflex activation, (ii) increased pulmonary ventilation and/or (iii ...

Mean quantum sojourn time

, 1999
Summary: This article introduces the notion of mean quantum sojourn time for a quantum dynamical semigroup acting over an arbitrary von Neumann algebra. This notion is used to analyze the asymptotic behaviour of the underlying dynamics and allows one to include, as a particular case, earlier classification of states obtained in scattering theory ...

Survival by Detection Pathway in Patients With Lung Cancer—A Nationwide Descriptive Epidemiological Study in Japan

International Journal of Cancer, Volume 159, Issue 4, Page 904-914, 15 August 2026.
Lung cancer is detected primarily through screening, incidental findings, or presentation with symptoms. In Japan, the impact of detection pathway on prognosis is poorly understood, limiting evaluation of screening effectiveness. The authors of the present study analyzed Japanese National Cancer Registry data, comparing clinical characteristics and net
