We show that a non-Markovian behavior can appear in a type of Markovian multimeric channel. Such a channel consists of N independent subunits, and each subunit has at least one open state and more than one closed state. Suppose the open state of the channel is defined as M out of N subunits in the open state with N>M>0. We show that, although the gating dynamics for each subunit between open and closed states is Markovian, the channel can show a memory behavior of weak anti-cross-correlation between the adjacent open and closed durations. Our study indicates that a non-Markovian binary time series can be obtained from a linear superposition of some independent channel subunits with Markovian gating dynamics.

Displacement and stress response of open-web girders under near field explosive loading.
Sci Rep
December 2024
Research Center of Space Structures, Guizhou University, Guiyang, 550025, China.
This study employed numerical simulation to investigate the dynamic response characteristics of open-web girders subjected to proximity blast loading and to compare these characteristics with those of solid-web girders. The research utilized the Coupled Eulerian-Lagrangian (CEL) method for simulation, effectively combining the advantages of both Eulerian and Lagrangian approaches. This method mitigated issues related to mesh distortion while accurately modeling the damage inflicted by blast loads on the structures.

DNA-based mapping tools help to address this challenge, but they are only able to transfer annotation between closely-related species. Here we introduce LiftOn, a homology-based software tool that integrates DNA and protein alignments to enhance the accuracy of genome-scale annotation and to allow mapping between relatively distant species.

Script training is a speech-language intervention designed to promote fluent connected speech via repeated rehearsal of functional content. This type of treatment has proven beneficial for individuals with aphasia and apraxia of speech caused by stroke and, more recently, for individuals with primary progressive aphasia (PPA). In the largest study to-date evaluating the efficacy of script training in individuals with nonfluent/agrammatic primary progressive aphasia (nfvPPA; Henry et al.

Sleep Breath
December 2024
Department of Anatomy, Faculty of Medicine, Istanbul Medeniyet University, Istanbul, Türkiye.
Objective: This study investigated the effects of sleep deprivation (SD) on balance after normal sleep, 24 h of SD, and subsequent rest under eyes-open (EO) and eyes-closed (EC) conditions. Our aim was to ascertain whether the reduced efficiency of balance control following SD is generalized or selective.
Method: Nineteen participants (12 females, 7 males) completed the Pittsburgh Sleep Quality Index (PSQI).
Serial Dependence in Smooth Pursuit Eye Movements of Preadolescent Children and Adults.
Invest Ophthalmol Vis Sci
December 2024
School of Psychology and Cognitive Science, East China Normal University, Shanghai, China.
Purpose: Serial dependence refers to the attraction of current perceptual responses toward previously seen stimuli. Despite extensive research on serial dependence, fundamental questions, such as how serial dependence changes with development, whether it affects the perception of sensory input, and what qualifies as serial dependence, remain unresolved. The current study aims to address these questions.
