A continuum-tree-valued Markov process [PDF]

open access: yes, 2012
We present a construction of a L\'evy continuum random tree (CRT) associated with a super-critical continuous state branching process using the so-called exploration process and a Girsanov's theorem.

Alterations of Functional Connectivity During the Resting State and Their Associations With Visual Memory in College Students Who Binge Drink

open access: yesFrontiers in Human Neuroscience, 2020
This study investigated the characteristics of neural oscillation and functional connectivity (FC) in college students engaging in binge drinking (BD) using resting-state electroencephalography (EEG). Also, the associations of visual memory, evaluated by

Generation of theta activity (RSA) in the cingulate cortex of the rat [PDF]

open access: yes, 1982
Unit activity recorded from the cingulate cortex during theta rhythm shows periodic trains of spikes which are phase-locked to the local theta field potential waves. These cortical theta units were also shown to be correlated with hippocampal theta units.

Exergaming in older adults: the effects of game characteristics on brain activity and physical activity

open access: yesFrontiers in Aging Neuroscience, 2023
IntroductionExergames are increasingly used in rehabilitation settings for older adults to train physical and cognitive abilities. To meet the potential that exergames hold, they need to be adapted to the individual abilities of the player and their ...

Theta Method Dynamics [PDF]

open access: yesLMS Journal of Computation and Mathematics, 2000
AbstractLong-term solutions of the theta method applied to scalar nonlinear differential equations are studied in this paper. In the case where the equation has a stable steady state, lower bounds on the basin of non-oscillatory, monotonic attraction for the theta method are derived. Spurious period two solutions are then analysed.
