Serial dependence in time perception requires consistent motor responses, not shared memory alone
British Journal of Psychology, EarlyView.Abstract Serial dependence—the bias from recent experience on present response—has been attributed to shared memory representations, yet previous studies yielded contradictory findings about whether consistent motor responses are required. To address this debate in time perception, we tested whether serial dependence emerges when tasks share identical ...

Bitcoin Cycle through Markov Regime-Switching Model
Engineering ProceedingsWe analyzed Bitcoin’s cyclical patterns used by the Markov regime-switching model and explored the impacts of inflation and the US Dollar Index on Bitcoin’s cyclicality.

Power priors for latent variable mediation models under small sample sizes
British Journal of Mathematical and Statistical Psychology, EarlyView.Abstract Latent variable models typically require large sample sizes for acceptable efficiency and reliable convergence. Appropriate informative priors are often required for gainfully employing Bayesian analysis with small samples. Power priors are informative priors built on historical data, weighted to account for non‐exchangeability with the ...

Brain Pathology, EarlyView.How glioblastoma organoids are made shapes what they become. Fragment‐based cultures preserve extracellular matrix networks, cellular diversity, and primary tumor identity, whereas dissociation‐based cultures shift toward growth‐adapted states and simplified microenvironments. Abstract Patient‐derived tumor organoids are widely used in cancer research,

Frontiers in Applied Mathematics and StatisticsThis research is devoted to studying a geometric Brownian motion with drift switching driven by a 2 × 2 Markov chain. A discrete-time multiplicative approximation scheme was developed, and its convergence in Skorokhod topology to the continuous-time ...

British Journal of Pharmacology, EarlyView.Background and Purpose G protein‐coupled receptors (GPCRs) are integral membrane proteins that mediate physiological processes by enabling cells to detect and respond to diverse stimuli. Although many subfamily‐specific functional hotspots have been described, the family‐wide determinants of common and subfamily‐specific functions remain incomplete ...

Edge‐preserving noise for diffusion models
Computer Graphics Forum, EarlyView.Abstract Classical diffusion models typically rely on isotropic Gaussian noise, treating all regions uniformly and overlooking structural information important for high‐quality generation. We introduce an edge‐preserving diffusion process that generalizes isotropic models via a hybrid noise scheme with an edge‐aware scheduler that smoothly transitions ...
