Comparative Process Mining for Identifying the Critical Activities in Sepsis Trajectories

open access: yesHealthcare Technology Letters
Sepsis, a life‐threatening condition with high mortality and readmission rates, demands precise and timely management to improve patient outcomes. Despite advancements, identifying the critical activities within sepsis treatment pathways remains a ...

A novel method for generating the optimal routing matrix of queuing networks with batch service [PDF]

open access: yesИзвестия Саратовского университета. Новая серия: Математика. Механика. Информатика
In this paper, we consider a large-scale open queuing network. The arrival process in the queueing network is Poissonian. Сustomer transitions between nodes are described by the routing matrix.

On the Distribution of Sojourn Times in Tandem Queues

open access: yesACM SIGMETRICS Performance Evaluation Review
The paper studies the (end-to-end) waiting and sojourn times in tandem queues with general arrivals and light-tailed service times. It is shown that the tails of the corresponding distributions are subject to polynomial-exponential upper bounds, whereby the degrees of the polynomials depend on both the number of bottleneck queues and the 'light ...

Ventilatory and cerebrovascular responses to exercise in lowlander children acclimatizing to high‐altitude

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend To investigate age‐related differences in ventilatory and cerebrovascular responses to exercise at high‐altitude, adults (n = 10, 23–44 years) and children (n = 8, 7–14 years) completed progressive cycling exercise tests at sea‐level and following 6 days of acclimatization at 3800 m.

Assessing the value of screening tools: reviewing the challenges and opportunities of cost-effectiveness analysis

open access: yesPublic Health Reviews, 2018
Background Screening is an important part of preventive medicine. Ideally, screening tools identify patients early enough to provide treatment and avoid or reduce symptoms and other consequences, improving health outcomes of the population at a ...

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${

The sojourn time distribution in an infinite server resequencing queue with dependent interarrival and service times [PDF]

open access: yes, 2002
We consider an infinite server resequencing queue, where arrivals are generated by jumps of a semi-Markov process and service times depend on the jumps of this process. The stationary distribution of the sojourn time, conditioned on the state of the semi-

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).
