Modeling High Frequency Data with Long Memory and Structural Change: A-HYEGARCH Model

open access: yesRisks, 2018
In this paper, we propose an Adaptive Hyperbolic EGARCH (A-HYEGARCH) model to estimate the long memory of high frequency time series with potential structural breaks.

Long Days Enhance Recognition Memory and Increase Insulin-like Growth Factor 2 in the Hippocampus [PDF]

open access: yes, 2017
Light improves cognitive function in humans; however, the neurobiological mechanisms underlying positive effects of light remain unclear. One obstacle is that most rodent models have employed lighting conditions that cause cognitive deficits rather than ...
