An investigation of the relation between online and offline violence: methodological and theoretical considerations [PDF]
Frontiers in PsychologyIntroductionResearch focusing on whether exposure to “online” violence via social media (exposure to violent content, such as videos of beatings or fights) predicts the use of physical “offline” violence (from hitting and threatening someone to violence ...

Stat, 2013 In many failure mechanisms, most subjects under study deteriorate physically over time, and thus a depreciation in health may precede failure. A latent stochastic process, called degradation process, may be assumed for modeling such depreciation whereby an event occurs when the process first crosses a threshold.

Approximating First Hitting Point Distribution in Milestoning for Rare Event Kinetics. [PDF]
Journal of Chemical Theory and Computation, 2023 Milestoning is an efficient method for rare event kinetics calculation using short trajectory parallelization. Mean first passage time (MFPT) is the key kinetic output of Milestoning, whose accuracy crucially depends on the initial distribution of the ...

Causal Inference in Threshold Regression and the Neural Network Extension (TRNN)
Stats, 2023 The first-hitting-time based model conceptualizes a random process for subjects’ latent health status. The time-to-event outcome is modeled as the first hitting time of the random process to a pre-specified threshold.

Map Lattices Coupled by Collisions: Hitting Time Statistics and Collisions Per Lattice Unit [PDF]
Annales de l'Institute Henri Poincare. Physique theorique, 2021 We study map lattices coupled by collision and show how perturbations of transfer operators associated with the spatially periodic approximation of the model can be used to extract information about collisions per lattice unit. More precisely, we study a

Hitting time of rapid intensification onset in hurricane-like vortices [PDF]
The Physics of Fluids, 2021 Predicting tropical cyclone (TC) rapid intensification (RI) is an important yet challenging task in current operational forecast due to our incomplete understanding of TC nonlinear processes. This study examines the variability of RI onset, including the

Hitting statistics from quantum jumps [PDF]
Quantum, 2017 We define the hitting time for a model of continuous-time open quantum walks in terms of quantum jumps. Our starting point is a master equation in Lindblad form, which can be taken as the quantum analogue of the rate equation for a classical continuous ...

An Imperfect Repair Model with Delayed Repair under Replacement and Repair Thresholds
Mathematics, 2022 Based on the extended geometric process, a repair replacement model of a degradation system is studied, in which the delayed repair time depends on the working time after the last repair. Replacement and repair thresholds describe when the system will be

Regression Models for Lifetime Data: An Overview
Stats, 2022 Two methods dominate the regression analysis of time-to-event data: the accelerated failure time model and the proportional hazards model. Broadly speaking, these predominate in reliability modelling and biomedical applications, respectively.
