Real roots of Dirichlet 𝐿-series [PDF]
Bulletin of the American Mathematical Society, 1949 Verf. betrachtet \(L(s,\chi)\), wobei \(\chi\) eine reeller Charakter mod \(k\), aber nicht Hauptcharakter ist. Es wird gezeigt, daß \(L(s,\chi)\ne 0\) für reelles positives \(s\) und \(2\le k\le 67\). Die Methoden des Verf. sind nach seinen Angaben auch für \(67\le k\le 227\) anwendbar, mit Ausnahme von \(k = 148\) und \(k = 163\). Diese Ausnahmefälle

From tetrachoric to kappa: How to assess reliability on binary scales
British Journal of Mathematical and Statistical Psychology, EarlyView.Abstract Reliability is crucial in psychometrics, reflecting the extent to which a measurement instrument can discriminate between individuals or items. While classical test theory and intraclass correlation coefficients are well‐established for quantitative scales, estimating reliability for binary outcomes presents unique challenges due to their ...

LLM‐based prior elicitation for Bayesian graphical modeling
British Journal of Mathematical and Statistical Psychology, EarlyView.ABSTRACT In the Bayesian graphical modeling framework, priors on network structure encode theoretical assumptions and uncertainty about the topology of psychological constructs under study. For instance, the Bernoulli prior specifies the probability of each pairwise interaction, the Beta–Bernoulli prior governs expected network density, and the ...

On certain classes of Dirichlet series with real coefficients absolute convergent in a half-plane
Математичні СтудіїFor $h>0$, $\alpha\in [0,h)$ and $\mu\in {\mathbb R}$ denote by $SD_h(\mu, \alpha)$ a class of absolutely convergent in the half-plane $\Pi_0=\{s:\, \text{Re}\,s\alpha$ for all $s\in \Pi_0$,} \smallskip\noi and let $\Sigma D_h(\mu, \alpha)$ be ...

Hierarchical Differentiable Fluid Simulation
Computer Graphics Forum, EarlyView.We introduce a two‐step algorithm that significantly reduces memory usage for solving control problems using differentiable fluid simulation techniques: our method first optimizes for bulk forces at reduced resolution, then refines local details over sub‐domains while maintaining differentiability. In trading runtime for memory, it enables optimization

Fast Injective Mesh Parameterization via Beltrami Coefficient Prolongation
Computer Graphics Forum, EarlyView.Abstract We present a highly efficient and robust method for free boundary injective parameterization of disk‐like triangle meshes with low isometric distortion. Harmonic function–based approaches, grounded in a strong mathematical framework, are widely employed.

Volume Quantization with Flexible Singularities for Hexahedral Meshing
Computer Graphics Forum, EarlyView.Abstract We present a novel algorithm for quantization and subsequent hexahedral mesh generation from seamless volumetric maps. Quantization is the process of choosing integers that represent the numbers of hexahedral elements to be placed in each region of the volume, and transforming the seamless map into an integer‐grid map matching that choice ...

Generalized and modified orders of growth for Dirichlet series absolutely convergent in a half-plane
Математичні СтудіїLet $\lambda=(\lambda_n)_{n\in\mathbb{N}_0}$ be a non-negative sequence increasing to $+\infty$, $\tau(\lambda)=\varlimsup_{n\to\infty}(\ln n/\lambda_n)$, and $\mathcal{D}_0(\lambda) $ be the class of all Dirichlet series of the form $F(s)=\sum_{n=0 ...

Skeletal‐Driven Animation of Anatomical Humans via Neural Deformation Gradients
Computer Graphics Forum, EarlyView.Abstract Most real‐time animation techniques for digital humans are limited to deforming the outer skin surface. Geometric skinning methods are highly efficient but struggle with artifacts such as collapsing joints or self‐intersections when animating inner anatomy along with the outer skin.

Computer Graphics Forum, EarlyView.Abstract Cutout animation is one of the earliest forms of animation, and to this day remains a popular technique featured in numerous films including Monty Python and South Park series. Most computer animation systems, however, focus on different styles, including cel animation, making cutout animation somewhat underexplored.
