Control of reaction-diffusion equations on time-evolving manifolds
, 2016 Among the main actors of organism development there are morphogens, which are signaling molecules diffusing in the developing organism and acting on cells to produce local responses. Growth is thus determined by the distribution of such signal. Meanwhile,

Physical Education Theory and MethodologyBackground. Auditory and visual reaction time refers to the duration between the introduction of a sound or light and the onset of a response. It is an important aspect of human behaviour, influencing performance in various activities ranging from daily ...

Convection-Diffusion-Reaction equation with similarity solutions [PDF]
, 2018 We consider similarity solutions of the generalized convection-diffusion-reaction equation with both space- and time-dependent convection, diffusion and reaction terms. By introducing the similarity variable, the reaction-diffusion equation is reduced to an ordinary differential equation. Matching the resulting ordinary differential equation with known

Chemical Reaction Dynamics within Anisotropic Solvents in Time-Dependent Fields [PDF]
, 2004 The dynamics of low-dimensional Brownian particles coupled to time-dependent driven anisotropic heavy particles (mesogens) in a uniform bath (solvent) have been described through the use of a variant of the stochastic Langevin equation.

Viewing Cute Images Does Not Affect Performance of Computerized Reaction Time Tasks
Frontiers in Psychology, 2022 Humans are emotionally affected by cute or infantile appearances, typical of baby animals and humans, which in turn often leads to careful and cautious behavior.

An upper bound for the bulk burning rate for systems [PDF]
, 2000 We consider a system of reaction-diffusion equations with passive advection term and Lewis number not equal to one. Such systems are used to describe chemical reactions in a flow in a situation where temperature and material diffusivities are not equal.

Influence of reaction conditions on the properties of solution-processed Cu2ZnSnS4 nanocrystals [PDF]
, 2014 Cu2ZnSnS4 nanocrystals were fabricated by hot injection of sulphur into a solution of metallic precursors. By careful control of the reaction conditions it was possible to control the elemental composition of the nanocrystals such that they are suitable ...

Journal of Intelligence, 2016 Within the mental speed approach to intelligence, the worst performance rule (WPR) states that the slower trials of a reaction time (RT) task reveal more about intelligence than do faster trials.
