Reliability measures in knowledge structure theory

open access: yesBritish Journal of Mathematical and Statistical Psychology, EarlyView.
Abstract In knowledge structure theory (KST) framework, this study evaluates the reliability of knowledge state estimation by introducing two key measures: the expected accuracy rate and the expected discrepancy. The accuracy rate quantifies the likelihood that the estimated knowledge state aligns with the true state, while the expected discrepancy ...

Estimation of comparable standardized mean differences in cluster randomized trials with covariate adjustment

open access: yesBritish Journal of Mathematical and Statistical Psychology, EarlyView.
Abstract Standardized mean differences (SMDs) are widely used to quantify treatment effects in cluster‐randomized trials. However, covariate adjustment in hierarchical linear models reduces the residual variance components used for standardization, which artificially inflates effect size estimates and undermines comparability across studies. We propose

Register‐Efficient Linear‐Time Evaluation in the Bernstein Basis

open access: yesComputer Graphics Forum, EarlyView.
Abstract We investigate the evaluation of points and derivatives of Bézier curves and surfaces on modern architectures, focusing on performance and guided by numerical error bounds. While the de Casteljau algorithm remains the reference for numerical robustness, its linear working‐set size imposes substantial register pressure on GPUs.

The big impact of small change: Fresh estimates of English wheat market integration, 1693–1893

open access: yesThe Economic History Review, EarlyView.
Abstract Using existing and new price data sets, we provide the first estimates of market integration across England over the entire 200 years of the industrial revolution. We document a significant, though not huge, integration improvement for markets furthest from London. Full integration was achieved by the 1830s. Our price data sets vary in quality

Fatigue of AM TiAl6V4: Probabilistic Modelling of the Size Influence as a Transfer Method From Test Specimen to Part

open access: yesFatigue &Fracture of Engineering Materials &Structures, EarlyView.
ABSTRACT This paper investigates the fatigue behavior of additively manufactured TiAl6V4 by comparing two specimen geometries with different highly stressed volumes. A fracture mechanical approach based on the El‐Haddad–Smith–Topper model is combined with defect analysis through X‐ray computed tomography.

On Integral Priors for Multiple Comparison in Bayesian Model Selection

open access: yesInternational Statistical Review, EarlyView.
Summary Noninformative priors constructed for estimation purposes are usually not appropriate for model selection and testing. The methodology of integral priors was developed to get prior distributions for Bayesian model selection when comparing two models, modifying initial improper reference priors. We propose a generalisation of this methodology to

Never, Ever Getting Started: On Prospect Theory Without Commitment

open access: yesMathematical Finance, EarlyView.
ABSTRACT Prospect theory is arguably the most prominent alternative to expected utility theory. We study the investment or gambling behavior of a prospect theory decision maker who is aware of his time‐inconsistency but lacks commitment. For the empirically relevant prospect theory specifications, we obtain the extreme prediction that such a decision ...

Room for Improvement: Why Finitist Arguments Do Not Check Out

open access: yesAnalytic Philosophy, EarlyView.
ABSTRACT We examine several new and underexplored arguments for the finitude of the past and the impossibility of Hilbert's Hotel. The first argument concludes that Hilbert's Hotel is impossible due to an alleged contradiction arising from the causal powers of infinitely many guests.

Advanced Posterior Analyses of Hidden Markov Models: Finite Markov Chain Imbedding and Hybrid Decoding

open access: yesScandinavian Journal of Statistics, EarlyView.
ABSTRACT Two major tasks in applications of hidden Markov models are to (i) compute distributions of summary statistics of the hidden state sequence, and (ii) decode the hidden state sequence. We describe finite Markov chain imbedding (FMCI) and hybrid decoding to solve each of these two tasks.

On the additive image of zeroth persistent homology

open access: yesTransactions of the London Mathematical Society, Volume 13, Issue 1, December 2026.
Abstract For a category X$X$ and a finite field F$F$, we study the additive image of the functor H0(−;F)∗:rep(X,Top)→rep(X,VectF)$\operatorname{H}_0(-;F)_* \colon \operatorname{rep}(X, \mathbf {Top}) \rightarrow \operatorname{rep}(X, \mathbf {Vect}_F)$, or equivalently, of the free functor rep(X,Set)→rep(X,VectF)$\operatorname{rep}(X, \mathbf {Set ...
