FPGA‐Based Real‐Time Implementation of Closed‐Loop Brain‐Controlled Eye Movement System
ABSTRACT This paper presents a comprehensive closed‐loop brain‐eye movement framework, spanning parametric modelling, dynamic analysis and real‐time FPGA implementation. A simplified first‐order oculomotor model was derived from the classical Robinson formulation to preserve the essential neural‐mechanical feedback structure while enabling efficient ...

We show that complexity, but not nestedness or modularity, increase dynamical stability of mutualistic networks, mainly through a weakening in mutualistic dependencies with complexity. Abstract Mutualistic networks provide essential contributions to long‐term ecosystem functioning and food security, but Anthropocene stressors continue to alter their ...

Unraveling authoritarian reform decision‐making: A metacognitive–subcognitive model
Abstract Recent research indicates that state reforms in East and Southeast Asia have been predominantly top‐down and authoritarian‐led. However, this significant observation implicitly relies on important assumptions about authoritarian decision‐making behavior and psychology that remains understudied.

A tutorial for understanding SEM using R: Where do all the numbers come from?
Abstract Structural equation modeling (SEM) is often seen as a complex and difficult method, especially for those who want to understand how the numbers in SEM software output are actually computed. Although many open‐source SEM tools are now available—especially in the R programming environment—looking into their source code to understand the ...

An extension of the basic local independence model to multiple observed classifications
Abstract The basic local independence model (BLIM) is appropriate in situations where populations do not differ in the probabilities of the knowledge states and the probabilities of careless errors and lucky guesses of the items. In some situations, this is not the case. This work introduces the multiple observed classification local independence model

Asymptotic standard errors for reliability coefficients in item response theory
Abstract In a recent review, Liu et al. (Psychological Methods, 2025b) classified reliability coefficients into two types: classical test theory (CTT) reliability and proportional reduction in mean squared error (PRMSE). This article focuses on quantifying the sampling variability of these coefficients under item response theory (IRT) models.

Bias and precision in true‐score estimation
Abstract We discuss two approaches to estimating the true score from classical test theory, each with a corresponding measure of uncertainty due to measurement error: the classical method with the standard error of measurement (SEM) and Kelley's method with the standard error of estimation (SEE).
