Exploring dependence structures among European electricity markets: static and dynamic copula-GARCH and dynamic state-space approaches by Ly, Sel, Sriboonchitta, Songsak, Tang, Jiechen, Wong, Wing-Keung

“…Based on the results of the ARMA-GJR-GARCH model, we first find that there are spillover effects in the returns of both base and peak spot prices in the five European electricity markets, and there are heteroskedastic, asymmetric, and leverage effects with negative and positive shocks, including spikes and drops during both base and peak load periods. …”

Culture of human pluripotent stem cells and neural networks in 3D using an optogenetic approach and a hydrogel model by Lee, S

“…</p> <p>The optogenetically modified neurons were found responsive to light stimulation, showing firing patterns and calcium events typical of early developing neurons (e.g. mixed and burst waves; single and multipeak spikes). Neuronal activities were assessed using calcium imaging. …”

Energy storage management for renewable energy systems by Feng, Xue

“…Compared with two conventional methods, the proposed control method for the HES demonstrates improved efficiency of involving the ultracapacitors to handle power spikes while protecting batteries from misuse. …”

Global burden of 288 causes of death and life expectancy decomposition in 204 countries and territories and 811 subnational locations, 1990–2021: a systematic analysis for the Glob... by Naghavi, M, Ong, KL, Aali, A, Almidani, O, Bandyopadhyay, S, Basnyat, B, Maude, R, Dolecek, C, Lacey, BWH

“…These estimates are particularly important following large-scale mortality spikes, such as the COVID-19 pandemic. When systematically analysed, mortality rates and life expectancy allow comparisons of the consequences of causes of death globally and over time, providing a nuanced understanding of the effect of these causes on global populations. …”
