Alternating Spatial‐Temporal Optimization for Continuous Collision Detection of Signed Distance Fields

open access: yesComputer Graphics Forum, EarlyView.
Abstract We present a fast, robust method for continuous collision detection (CCD) directly between pairs of complex signed distance fields (SDFs). By casting CCD as an alternating spatio‐temporal optimization and driving a small set of smartly sampled surface points along SDF tangent spaces, our approach avoids dense sampling or triangle meshes ...

Advances in 4D Representation: Geometry, Motion, and Interaction

open access: yesComputer Graphics Forum, EarlyView.
We survey 4D representation through three key pillars — geometry, motion, and interaction — offering a selective, representation‐centric perspective to guide researchers in choosing and customizing the right 4D representation for their tasks. Abstract We present a survey on 4D generation and reconstruction, a fast‐evolving subfield of computer graphics

Preimage Attack on Parallel FFT-Hashing

open access: yes, 2008
Vaudenay in 1993. The function is a simple and light weight hash algorithm with 128-bit digest. Its basic component is a multi-permutation which helps in proving its resistance to collision attacks.

Entangling and Coalescing on Social Media: A Study of Issue Boundary Spanning in Movement of Movements

open access: yesInformation Systems Journal, EarlyView.
ABSTRACT This study examines how issues across boundaries influence contention dynamics in a movement of movements on social media. Participants utilize social media to support or oppose goals and actions related to their visions regarding societal changes. As the boundaries of movements are fluid on social media, we investigate the actors' identities,

Spectral Embedded Hashing for Scalable Image Retrieval

open access: yes, 2014
We propose a new graph based hashing method called spectral embedded hashing (SEH) for large-scale image retrieval. We first introduce a new regularizer into the objective function of the recent work spectral hashing to control the mismatch between the

The Making of the EU's Geoeconomic ‘Bazooka’: The Anti‐Coercion Instrument and the Role of Think Tanks in European Union Foreign Policy

open access: yesJCMS: Journal of Common Market Studies, EarlyView.
Abstract The Anti‐Coercion Instrument (ACI), the most powerful tool in the EU's geoeconomic arsenal, has its origins in the first Trump US presidency and has recently been brandished again as a potential response to Trump's coercive tariffs. Its centrality to the EU's ‘geoeconomic turn’ and the twists and turns of its legislative history have been ...

A double‐blind randomized controlled trial of personalized upper‐alpha neurofeedback in children with ADHD

open access: yesJournal of Child Psychology and Psychiatry, EarlyView.
Background Neurofeedback (NF) is a nonpharmacological approach for ADHD, but standard protocols often overlook individual EEG variability, potentially limiting efficacy. We report the first double‐blind randomized controlled trial of a session‐adaptive individualized upper‐alpha NF protocol in children with ADHD, based on individualized 1/f + alpha ...

Entrepreneurial Market Leadership Claims, Cultural Resonance, and Investor Evaluations in Nascent Markets: The Goldilocks Effect

open access: yesJournal of Management Studies, EarlyView.
Abstract Cultural entrepreneurship research emphasizes entrepreneurs’ use of cultural resources to influence audience evaluations through resonance. However, the process by which such cultural resonance is achieved remains underexplored, particularly as an intermediary outcome.
