Variable Selection for Illness‐Death Processes Under Dual Observation Schemes
Statistics in Medicine, Volume 45, Issue 13-14, June 2026.ABSTRACT The classical illness‐death process offers a useful framework for studying the progression of chronic disease while jointly modeling death. In many settings the time of disease progression is not observed directly, but progression status is recorded at intermittent assessment times.

A discrete-time system with service control and repairs
International Journal of Applied Mathematics and Computer Science, 2014 This paper discusses a discrete-time queueing system with starting failures in which an arriving customer follows three different strategies. Two of them correspond to the LCFS (Last Come First Served) discipline, in which displacements or expulsions of ...

European Journal of Neurology, Volume 33, Issue 6, June 2026.Siponimod lowered the risk of wheelchair use in SPMS patients compared to placebo, especially in those with active disease. Time to wheelchair is a key metric for evaluating treatment in SPMS. ABSTRACT Background Delaying time to requiring a wheelchair in people living with MS is an important treatment goal to maintain quality of life and guard against

Randomized assignment of jobs to servers in heterogeneous clusters of shared servers for low delay
Stochastic Systems, 2016 We consider the problem of assignning jobs to servers in a multi-server system consisting of N parallel processor sharing servers, categorized into M (≪N) different types according to their processing capacities or speeds.
