295 Applying human-centered design to develop and refine a cervical cancer screening intervention for people experiencing homelessness [PDF]

open access: yesJournal of Clinical and Translational Science
Objectives/Goals: People experiencing homelessness (PEH) face disproportionate cervical cancer burden and screening barriers. Our goal was to design a tailored intervention involving community health worker (CHW)-led education and delivery of context ...

Optional Sampling of Submartingales Indexed by Partially Ordered Sets

open access: yesAnnals of Probability, 1981
The optional sampling theorem for martingales indexed by a partially ordered set is true if the index set is directed. However, the corresponding result for submartingales indexed by a partially ordered set is not true in general. In this paper we completely characterize the class of stopping times for which the optional sampling theorem is true for ...

The Optional Sampling Theorem for Martingales Indexed by Directed Sets

open access: yesAnnals of Probability, 1980
A natural generalization of the optional sampling theorem for martingales is given. For discrete valued stopping times the result holds for directed sets; for more general stopping times the result holds for lattices satisfying a type of separability condition. The discrete case improves a lemma of Chow.

Doob’s optional sampling theorem in Riesz spaces

open access: yesPositivity, 2011
This paper is a continuation of the author's paper [Positivity 14, No. 4, 731--751 (2010; Zbl 1216.46005)] where the author defined continuous time stochastic processes in Riesz spaces and proved the Doob-Meyer decomposition theorem for martingales. In this paper the notions of stopping times and stopped processes for continuous stochastic processes ...

The Perils of Misspecified Priors and Optional Stopping in Multi-Armed Bandits

open access: yesFrontiers in Artificial Intelligence, 2021
The connection between optimal stopping times of American Options and multi-armed bandits is the subject of active research. This article investigates the effects of optional stopping in a particular class of multi-armed bandit experiments, which ...

A protocol for representative sampling of solid tumors to improve the accuracy of sequencing results

open access: yesSTAR Protocols, 2021
Summary: Owing to spatial segregation of tumor subclones, solid tumor sampling using formalin-fixed, paraffin-embedded blocks is often inadequate to represent the genomic heterogeneity of solid tumors.

R-package LNIRT for joint modeling of response accuracy and times [PDF]

open access: yesPeerJ Computer Science, 2023
In computer-based testing it has become standard to collect response accuracy (RA) and response times (RTs) for each test item. IRT models are used to measure a latent variable (e.g., ability, intelligence) using the RA observations.
