Sojourn time tails in the single server queue with heavy-tailed service times [PDF]

, 2009
We consider the GI/GI/1 queue with regularly varying service requirement distribution of index -a. It is well known that, in the M/G/1 FCFS queue, the sojourn time distribution is also regularly varying, of index 1 - a, whereas in the case of LCFS or ...

A Statistical Method to Schedule the First Exam Using Chest X-Ray in Lung Cancer Screening

Mathematics
We applied a recently developed statistical method to the National Lung Screening Trial (NLST) chest X-ray data, to find the optimal time for initiating chest X-ray screening in asymptomatic individuals. Incidence probability was used to control the risk

Daily hot‐water immersion preserves altitude‐induced haemoglobin mass expansion following descent independent of erythropoietin

Experimental Physiology, EarlyView.
Abstract High‐altitude exposure increases haemoglobin mass (Hbmass), a key determinant of arterial oxygen‐carrying capacity, but following descent this adaptation can regress toward baseline within 7 days. Long‐term heat acclimation has emerged as an alternative stimulus for Hbmass expansion; however, whether post‐altitude passive‐heat exposure can ...

The total sojourn time distribution in a stochastic compartmental model

Mathematical and Computer Modelling, 1989
The total time spent by both a single particle and by all the particles up to an instant in a particular compartment in a semi-Markov compartmental system is discussed. The stream of particles entering the system is a renewal process. The particles in the system behave independently of each other.

The role of acid‐base balance in cerebrovascular and ventilatory responses to CO2 during 10 h normobaric hypoxia

The Journal of Physiology, EarlyView.
Abstract figure legend During 10 h exposures to normobaric hypoxia exposure there was a selective leftward shift in ventilatory response to hyperoxic hypercapnic rebreathing, but not the cerebrovascular response. The key findings are that the resetting of the central chemoreflex to lower PCO2${P_{{\mathrm{C}}{{\mathrm{O}}_2}}}$ during early hypoxic ...

Robust Non-Fragile Control of Positive Semi-Markovian Jump Systems With Actuator Saturation

IEEE Access, 2019
This paper is concerned with the non-fragile control problem of the positive semi-Markovian jump systems with actuator saturation. For the semi-Markovian process, a class of non-exponential distributions is considered as the probability distribution of ...

ON THE SOJOURN TIME DISTRIBUTION IN CYCLIC QUEUEING SYSTEMS WITH A LiPS STATION

Journal of the Operations Research Society of Japan, 1987
In a closed tandem of exponential queueing systems the joint distribution of a customer's successive sojourn times during a cycle is investigated. The first station is a multi-server node under FCFS, while the second station works under ``limited processor-sharing'' regime, i.e.: up to a fixed number m of customers present at the station, the processor

Effects of nocturnal periodic breathing on sympathetic nerve activity and ventilatory control at high altitude: a randomised, crossover study

The Journal of Physiology, EarlyView.
Abstract figure legend Schematic overview of the randomised crossover study investigating the effects of nocturnal periodic breathing (nPB) on sympathetic activity and ventilatory acclimatisation in hypobaric hypoxia equivalent to 4000 m altitude. Participants completed two 3‐day sojourns where nPB was inhibited by increasing inspiratory CO2 fraction ...
