Archaeometry, EarlyView.ABSTRACT Riverine and valley systems across the globe have been central to the development of past urban centres. By AD 900, the Shashe and Limpopo Rivers seem to have facilitated the interaction and integration of early farming communities in southern Africa. This paper focuses on the application of geoarchaeological perspectives made available by the

Variable‐Rate Texture Compression: Real‐Time Rendering with JPEG
Computer Graphics Forum, EarlyView.Abstract Although variable‐rate compressed image formats such as JPEG are widely used to efficiently encode images, they have not found their way into real‐time rendering due to special requirements such as random access to individual texels. In this paper, we investigate the feasibility of variable‐rate texture compression on modern GPUs using the ...

NAADF: Globally Illuminated Voxel Worlds Accelerated with Nested Axis‐Aligned Distance Fields
Computer Graphics Forum, EarlyView.Abstract Achieving realistic rendering of 3D scenes in real time using path tracing is challenging due to the high sample count required, with ray tracing as the bottleneck. Focusing on voxels as a geometry representation offers significant opportunities for optimizations, especially for tracing the rays, but also for computing the samples.

Sparse Decomposition Technique for Segmentation and Compression of Compound Images
Journal of Intelligent Systems, 2018 Compression of compound records and images can be more cumbersome than the original information since they can be a mix of text, picture and graphics. The principle requirement of the compound record or images is the nature of the compressed data.

Equal Time, Unequal Labor Division: Adolescents' Domestic Labor Time During the COVID‐19 Pandemic
Sociological Inquiry, EarlyView.While existing research offers mixed evidence on how the COVID‐19 pandemic affected adults' division of housework, adolescents have remained largely overlooked in this regard. Using nationally representative data from the 2019–2021 American Time Use Survey and Current Population Survey, this study examines changes in adolescents' unpaid labor before ...
