On sojourn times at particular gene frequencies

open access: yesGenetical Research, 1975
SUMMARYThe distribution of visits to a particular gene frequency in a finite population of sizeNwith non-overlapping generations is derived. It is shown, by using well-known results from the theory of finite Markov chains, that all such distributions are geometric, with parameters dependent only on the set ofbij's, wherebijis the mean number of visits ...

Sojourn times in the $M/G/1$ queue with deterministic feedback [PDF]

open access: yes, 1989
In this paper we consider an M/G/1 queueing model, in which each customer is fed back a fixed number of times. For the case of negative exponentially distributed service times at each visit, we determine the Laplace-Stieltjes transform of the joint ...

Between soft power and suspicion: Chinese international students as diasporic actors in U.S.‐China geopolitical tensions

open access: yesBritish Educational Research Journal, EarlyView.
Abstract This study examines the under‐theorized political role and identity of Chinese international students, who emerge as significant actors caught between U.S. soft power ambitions and rising geopolitical suspicion. Amid escalating U.S.‐China tensions, these students are forced to confront environments shaped by competing geopolitical discourses ...

Evaluating the Impact of Age on Prostate Cancer Overdiagnosis Using Long‐Term Follow‐Up From the CAP Randomised Trial

open access: yesInternational Journal of Cancer, EarlyView.
Uncertainty persists over whether the benefits of prostate‐specific antigen (PSA) screening outweigh harms from overdiagnosis, a key barrier to population‐wide adoption. Here, English male mortality rates were analyzed alongside long‐term data from the UK Cluster Randomized Trial of PSA Testing for Prostate Cancer (CAP) to estimate age‐specific ...

The Evolution of Autonomous Systems for Planetary Cave Exploration: A Review

open access: yesJournal of Field Robotics, EarlyView.
ABSTRACT The exploration of Subsurface Access Points (SAPs), such as lava tubes on the Moon and Mars, has gained significant interest due to their potential as stable environments shielded from surface radiation and temperature extremes. These sites are considered high‐value targets for detecting water and signs of ancient life, and assessing their ...

The random walk with stochastic sojourn times [PDF]

open access: yes, 1969
In this thesis we will investigate random walks which, upon reaching a state X, stay in X during a certain time (sojourn time). The distribution of this time only depends on X and not on the previous development of the process.

Islam at the monastery: on infinity as subtractive truth L'islam au monastère : de l'infini comme vérité soustractive

open access: yesJournal of the Royal Anthropological Institute, EarlyView.
Based on ethnographic research at Rūm Orthodox Christian monasteries in Lebanon, the article studies scenes of Islam at the monastery as they intersect with anxious public debates on, and anthropological theorizations of, sectarianism and ‘Muslim–Christian’ relations in the Mashriq.

Sojourn times in Jackson networks [PDF]

open access: yes, 2012
Jackson queuing networks have a lot of practical applications, mainly in the modelling of computation and telecommunications networks. Evidently the time that one customer - a person, a job, a message … – spends in this kind of systems, its sojourn time,
