Frequency‐Aware Spatial‐Angular Gaussians for Efficient Global Illumination Precomputation and Real‐Time Rendering

Computer Graphics Forum, EarlyView.
Abstract Precomputation and efficient approximate material models are well‐known approaches for achieving real‐time rendering with global illumination. Recent research in radiance fields and in particular 3D Gaussian Splatting has demonstrated the power of Gaussian primitives both to represent radiance and for fast optimization.

A Splitting Architecture for Exact Reduced Coulomb Friction

Computer Graphics Forum, EarlyView.
Abstract Existing approaches to frictional contact dynamics typically either modify the Coulomb law to improve numerical robustness or solve the exact law in a fully coupled monolithic form. However, in its reduced form, exact Coulomb friction can be written as a cone complementarity problem with an augmented velocity, which reveals a natural split ...

Proxy Blind Signature Scheme based on Discrete Logarithm Problem and Elliptic Curve Discrete Logarithm Problem [PDF]

, 2010
In some applications, it is necessary to protect the privacy of the content of user from signer. Proxy blind signature can be used in these applications which combine the properties of both proxy signature and blind signature.

Testing the morphology‐ and intuition‐based taxonomic hypotheses using integrative approach: unexpected discovery of triplet of sibling species within a widespread Eurasian butterfly, Hyponephele lycaon

Cladistics, EarlyView.
Abstract In well‐studied groups of organisms, the taxonomic landscape can be very complex, with several alternative classifications describing diversity within the same set of populations. For example, three hypotheses have previously been proposed to describe the taxonomy of the common and widespread Eurasian Dusky Meadow Brown butterfly, Hyponephele ...

Fire frequency and timing influence bee–flower interactions: a case study from an oak‐pine savanna restoration on the Cumberland Plateau

Restoration Ecology, EarlyView.
Abstract Introduction Native plant communities have declined in the southeastern United States over the past century because of habitat loss and fire suppression. While restoration of these communities often requires prescribed fire, the effects of fire on endemic insects remain unclear.

New Explicit Conditions of Elliptic Curve Traces for FR-Reduction [PDF]

, 2001
Elliptic curve cryptosystems are based on the elliptic curve discrete logarithm problem (ECDLP). If elliptic curve cryptosystems avoid FR-reduction and anomalous elliptic curve over F_q, then with current knowledge we can construct elliptic curve ...

Algebraic divisibility sequences over function fields [PDF]

, 2011
In this note we study the existence of primes and of primitive divisors in function field analogues of classical divisibility sequences. Under various hypotheses, we prove that Lucas sequences and elliptic divisibility sequences over function fields ...

Teaching Through Making: |xam and !xun Material Culture of the Bleek and Lloyd Collection

Museum Anthropology, Volume 50, Issue 1, Spring 2027.
ABSTRACT At Wits Art Museum (University of the Witwatersrand, Johannesburg, South Africa) is a small collection donated to the former Wits Museum of Ethnology by Percival Kirby in 1952. A note in the accession register ties the items into the context of the renowned ‘Bushman researches’ of Wilhelm Bleek and Lucy Lloyd in Cape Town in the 1870s and ...
