Homogenization for Time-periodic KPP Reactions [PDF]
We prove homogenization for reaction-advection-diffusion equations with KPP reactions, in the time-periodic spatially stationary ergodic setting, and find an explicit formula for the homogenized dynamic. We also extend this result to models with non-local diffusion and KPP reactions.

Effect of handedness on visual, auditory and cutaneous reaction times in normal subjects [PDF]
Background & Objective: Simple reaction time is the time interval between stimulus and response. In this study the impact of handedness on auditory, visual and cutaneous simple reaction time have been investigated. Methods: 100 healthy male volunteers of

Antiepileptic Drugs, Reaction Time, and Impulsivity
The effects of antiepileptic drugs (AED) on reaction time, attention, and impulsivity in 111 epileptic children, aged 5 to 13 years, are reported from the Children’s Hospital of Los Angeles and University of Southern California School of Medicine.

Universal kinetics of imperfect reactions in confinement [PDF]
Chemical reactions generically require that particles come into contact. In practice, reaction is often imperfect and can necessitate multiple random encounters between reactants. In confined geometries, despite notable recent advances, there is to date no general analytical treatment of such imperfect transport-limited reaction kinetics.

Propagation phenomena for time heterogeneous KPP reaction-diffusion equations [PDF]
We investigate in this paper propagation phenomena for the heterogeneous reaction-diffusion equation $\partial_t u -\Delta u = f(t,u)$, $x\in R^N$, $t\in\R$, where f=f(t,u) is a KPP monostable nonlinearity which depends in a general way on t. A typical f

Reaction Time and Attention in Epilepsy
Reaction time, attention and impulsivity in 112 children with epilepsy (4.5-13 years) were studied using a computerized test at the Division of Neurology, Children’s Hospital Los Angeles, Los Angeles, CA.

A Query-Response Causal Analysis of Reaction Events in Biochemical Reaction Networks [PDF]
The stochastic kinetics of BRN are described by a chemical master equation (CME) and the underlying laws of mass action. The CME must be usually solved numerically by generating enough traces of random reaction events. The resulting event-time series can be evaluated statistically to identify, for example, the reaction clusters, rare reaction events ...

Modelling Chemical Reasoning to Predict Reactions [PDF]
The ability to reason beyond established knowledge allows Organic Chemists to solve synthetic problems and to invent novel transformations. Here, we propose a model which mimics chemical reasoning and formalises reaction prediction as finding missing links in a knowledge graph. We have constructed a knowledge graph containing 14.4 million molecules and
