Mechanisms of haemoglobin mass expansion following heat stress

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Theorised mechanisms of heat stress‐induced erythropoiesis which may facilitate the expansion of haemoglobin mass. A, acute: heat stress‐induced renal ischaemia. Redistribution of blood flow away from the kidneys to facilitate thermoregulation during heat stress could reduce renal oxygen delivery, subsequently lowering renal PO2${

Scheduling to Optimize Sojourn Time of Successful Jobs

open access: yes, 2022
Deep neural networks training jobs and other iterative computations frequently include checkpoints where jobs can be canceled based on the current value of monitored metrics.

Endocrine and androgenic response to altitude training in professional cyclists

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Steroidal and endocrine variables are altered during altitude training. Abstract This study investigated endocrine and steroidal blood markers in 31 male elite cyclists monitored over 7 weeks, including a 3 week altitude training camp either at 2050 m (n = 19) or 3000 m (n = 12).

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

open access: yesThe 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}}}$).

Approximations for the mean sojourn time in a parallel qeue [PDF]

open access: yes, 2009
This paper considers a parallel queue, which is two-queue network, where any arrival generates a job at both queues. The focus is on methods to quantify the mean value of the 'system's sojourn time' S: with Si denoting a job's sojourn time in queue i, S ...

Transport operator on phase spaces with finite time of sojourn property

open access: yesElectronic Journal of Differential Equations, 2010
In this article, the transport operator with general boundary conditions is discussed. According to a smallness hypothesis on the boundary operator and to finite time of sojourn property of phase spaces, we prove that the transport operator generates

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

open access: yesThe 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 ...

Collaborative mobile sink sojourn time optimization scheme for cluster-based wireless sensor networks

open access: yes, 2018
Wireless sensor networks (WSNs) have grown excessively due to their various applications and low installation cost. One of the design challenges of the WSNs is to balance the energy consumption among sensor nodes, which results in enhanced network ...
