C ∗ -Algebra of Cancellative Semigroupoids

open access: yesJournal of Mathematical Extension, 2009
In this paper the definition and some properties of semigroupoids are considered. Representations, tight representations, and universal representations of a cancellative semigroupoid are discussed.

The Truth, the Whole Truth, and Nothing but the Truth: Automatic Visualization Evaluation from Reconstruction Quality

open access: yesComputer Graphics Forum, EarlyView.
Abstract Recent advances in AI enable the automatic generation of visualizations directly from textual prompts using agentic workflows. However, visualizations produced via one‐shot generative methods often suffer from insufficient quality, typically requiring a human in the loop to refine the outputs.

Gauge algebra and diffeomorphisms in string field theory

open access: yesJournal of High Energy Physics
We consider the gauge algebra of closed string field theory with a focus on diffeomorphisms. This algebra contains off-shell information in two ways.

Scalable Computation of Topological Abstractions for Scalar Data

open access: yesComputer Graphics Forum, EarlyView.
Abstract Topological data analysis has become an important tool for large scale scalar data analysis and visualization, efficiently extracting the inherent structure and features of interest of the data. However, with growing dataset sizes and complexity, it is increasingly becoming infeasible to compute topological abstractions of interest in serial ...

On simplicity of Cuntz algebras and its applications [PDF]

open access: yesSurveys in Mathematics and its Applications
Cuntz algebra 𝒪2 is the universal C*-algebra generated by two isometries s1, s2 satisfying s1s1*+s2s2*=1. This is separable, simple, infinite C*-algebra containing a copy of any nuclear C*-algebra.

Fast Nodal Hessian Computation for Peridynamic Fracture Simulation

open access: yesComputer Graphics Forum, EarlyView.
A fast, exact nodal Hessian computation for Non‐Ordinary State‐Based Peridynamics is introduced through analytical simplification and a warp‐centric GPU strategy. The method accelerates preconditioned solvers and Vertex Block Descent, enabling interactive fracture simulation with physical accuracy.

FaceMamba: Geometry‐Aware Mamba for Efficient Speech‐Driven 3D Facial Animation

open access: yesComputer Graphics Forum, EarlyView.
Abstract Speech‐driven 3D facial animation plays a pivotal role in immersive digital human applications. Recent works have explored Mamba‐based sequence modeling as an efficient alternative to Transformer, but they often suffer from limited cross‐modal alignment and insufficient control over fine‐grained facial deformations.

Silicon Formalism: Rules, Standards, and Judge AI

open access: yesJournal of Empirical Legal Studies, EarlyView.
ABSTRACT This paper replicates a judicial experiment originally conducted on 61 U.S. federal judges, this time with GPT‐5 as the decision‐maker. The experiment involves a choice‐of‐law dispute in a hypothetical automobile accident case, where three variables are manipulated: (1) whether the applicable doctrine is a rule or a standard, (2) whether the ...

Green Bond Paper Topics, Journal Metrics and Post‐publication Diffusion

open access: yesJournal of Economic Surveys, EarlyView.
ABSTRACT Green bonds are important financial instruments in sustainable finance, generating a rapidly expanding academic literature. This paper identifies the topics analyzed in green bond academic research and examines how these topics are associated with journal and post‐publication diffusion metrics. Using 1048 paper abstracts published between 2015
