Relationships of attention and arousal are responsible for action in sports
Biomedical Human Kinetics, 2022 Study aim: The most important psychological mechanisms that are responsible for sports activity are arousal and attention. Study aim the relationships between the level of arousal and the level of attention, an attempt has been made to explain the ...

Subdiffusion--reaction process with $A\longrightarrow B$ reactions versus subdiffusion--reaction process with $A+B\longrightarrow B$ reactions [PDF]
Phys. Rev. E 90, 032136 (2014), 2014 We consider the subdiffusion-reaction process with reactions of a type A+B\arrow B (in which particles A are assumed to be mobile whereas B - static) in comparison to the subdiffusion-reaction process with A\rightarrow B reactions which was studied by I.M. Sokolov et al. in Phys. Rev. E 73, 031102 (2006).

Time Uncertainty and Choice Reaction Time
Nature, 1960 THE duration of the foreperiod, that is, the interval between some warning signal and the stimulus, has long since been known as one of the main factors which influence the length of simple reaction time2–4. Klemmer1 has recently shown that reaction time is shorter with brief (0.25 sec.) constant foreperiods than with either longer constant foreperiods

Similarity solutions of Reaction-Diffusion equation with space- and time-dependent diffusion and reaction terms [PDF]
, 2015 We consider solvability of the generalized reaction-diffusion equation with both space- and time-dependent diffusion and reaction terms by means of the similarity method. By introducing the similarity variable, the reaction-diffusion equation is reduced to an ordinary differential equation.

On the sum of chemical reactions [PDF]
arXiv, 2021 It is standard in chemistry to represent a sequence of reactions by a single overall reaction, often called a complex reaction in contrast to an elementary reaction. Photosynthesis $6 \text{CO}_2+6 \text{H}_2\text{O} \to \ \text{C}_6\text{H}_{12}\text{O}_6$ $+\ 6 \text{O}_2$ is an example of such complex reaction.

Non-Markovian polymer reaction kinetics [PDF]
Nature Chemistry, 4, 568-573 (2012), 2012 Describing the kinetics of polymer reactions, such as the formation of loops and hairpins in nucleic acids or polypeptides, is complicated by the structural dynamics of their chains. Although both intramolecular reactions, such as cyclization, and intermolecular reactions have been studied extensively, both experimentally and theoretically, there is to

Coherent chemical kinetics as quantum walks I: Reaction operators for radical pairs [PDF]
Phys. Rev. E 93, 032407 (2016), 2015 Classical chemical kinetics use rate-equation models to describe how a reaction proceeds in time. Such models are sufficient for describing state transitions in a reaction where coherences between different states do not arise, or in other words, a reaction which contain only incoherent transitions.
