, 2011 We study an inflationary model driven by a single minimally coupled standard kinetic term scalar field with a step in its mass modeled by an Heaviside step function.

Dynamic Looping of a Free-Draining Polymer
, 2017 We revisit the celebrated Wilemski-Fixman (WF) treatment for the looping time of a free-draining polymer. The WF theory introduces a sink term into the Fokker-Planck equation for the $3(N+1)$-dimensional Ornstein-Uhlenbeck process of the polymer dynamics,

Equivalence of Two Different Integral Representations of Droplet Distribution Moments in Condensing Flow [PDF]
, 2004 It is proved that two different and independently derived integral representations of droplet size distribution moments encountered in the literature are equivalent and, moreover, consistent with the general dynamic equation that governs the droplet size

Advances in Mathematical Physics, 2014 The meshless local Pretrov-Galerkin method (MLPG) with the test function in view of the Heaviside step function is introduced to solve the system of coupled nonlinear reaction-diffusion equations in two-dimensional spaces subjected to Dirichlet and ...

Sled acceleration control for low speed impact testing and transient response studies [PDF]
, 2014 Whiplash Associated Disorder is the most common soft-tissue injury arising from low-speed car crashes (Siskind et al. 2013). To better understand whiplash injury mechanisms in the head-neck system, a sled was acquired.

Exact distributions of the maximum and range of random diffusivity processes
New Journal of Physics, 2021 We study the extremal properties of a stochastic process x _t defined by the Langevin equation ${\dot {x}}_{t}=\sqrt{2{D}_{t}}\enspace {\xi }_{t}$ , in which ξ _t is a Gaussian white noise with zero mean and D _t is a stochastic ‘diffusivity’, defined as

A multiclass Lighthill-Whitham-Richards traffic model with a discontinuous velocity function
Networks and Heterogeneous Media, 2021 The well-known Lighthill-Whitham-Richards (LWR) kinematic model of traffic flow models the evolution of the local density of cars by a nonlinear scalar conservation law. The transition between free and congested flow regimes can be described by a flux or

Heaviside transform with respect to the mass in QCD
, 1996 We propose the use of Heaviside transform with respect to the quark mass to investigate dynamical aspects of QCD. We show that at large momentum transfer the transformed propagator of massive quarks behaves softly and thus the dominant effect of explicit
