Affinification: A Fine Approximation of Deformations
Computer Graphics Forum, EarlyView.Abstract We introduce affinification, a novel method for accelerating physics‐based animation of elastic solids. During a time‐dependent simulation, our method automatically partitions the space into affine and elastic regions depending on the deformation.

ReTrace: Interactive Visualizations for Reasoning Traces of Large Reasoning Models
Computer Graphics Forum, EarlyView.Abstract Recent advances in Large Language Models have led to Large Reasoning Models, which produce step‐by‐step reasoning traces. Such traces may offer insight into how models think, improving explainability and clarifying the underlying process. These traces, however, are often verbose and complex, making them cognitively demanding to comprehend ...

Differentiable Randers‐Finsler Eikonal Solvers
Computer Graphics Forum, EarlyView.Abstract Fast and differentiable solvers for anisotropic and asymmetric distance fields are a key primitive in geometry processing, enabling gradient‐based optimization over metrics, drift fields, and downstream objectives that depend on geodesic distances and geodesics.

Shareholder Activism: Affliction for Incumbent CEOs?
Financial Management, EarlyView.ABSTRACT We study how shareholder activism shapes CEO careers by distinguishing between two competing hypotheses: discipline and reallocation. Employing a control function approach with expected mutual fund fire sales and purchases as exclusion restrictions, we analyze 3799 US campaigns from 2006 to 2018.

International Statistical Review, EarlyView.Summary In high‐dimensional survival analysis, effective variable selection is crucial both for model interpretation and predictive performance. This paper investigates Cox regression with lasso and adaptive lasso penalties in genomic datasets where covariates far outnumber observations.

ID-based signature without trusted PKG
Tongxin xuebao, 2008 PKG（private key generater） scheme was presented to overcome Chen-Zhang-Kim’s scheme drawback about a large amount of computation and Gorantla-Saxena’s scheme drawback about needing trusted PKG.More precisely,under the random oracle model,the scheme is ...

The Random Oracle Methodology, Revisited
, 1998 We take a critical look at the relationship between the security of cryptographic schemes in the Random Oracle Model, and the security of the schemes that result from implementing the random oracle by so called \cryptographic hash functions".

International Transactions in Operational Research, EarlyView.Abstract This work aims at minimizing the energy purchase costs related to the operation of a green hydrogen production plant connected both to an intermittent, uncertain renewable energy source and to the power grid. We focus on scenarios where, for economic or environmental reasons, the plant must primarily meet hydrogen demand using electricity from
