Huffman coding with unequal letter costs [PDF]

open access: yesProceedings of the thiry-fourth annual ACM symposium on Theory of computing - STOC '02, 2002
(MATH) In the standard Huffman coding problem, one is given a set of words and for each word a positive frequency. The goal is to encode each word w as a codeword c(w) over a given alphabet. The encoding must be prefix free (no codeword is a prefix of any other) and should minimize the weighted average codeword size Σw freq w, |c(w)|. The problem has a

NAADF: Globally Illuminated Voxel Worlds Accelerated with Nested Axis‐Aligned Distance Fields

open access: yesComputer 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.

A Low-Complexity Lossless Compression Method Based on a Code Table for Infrared Images

open access: yesApplied Sciences
Traditional JPEG series image compression algorithms have limitations in speed. To improve the storage and transmission of 14-bit/pixel images acquired by infrared line-scan detectors, a novel method is introduced for achieving high-speed and highly ...

Equal Time, Unequal Labor Division: Adolescents' Domestic Labor Time During the COVID‐19 Pandemic

open access: yesSociological 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 ...

Entropy Coding Aided Adaptive Subcarrier-Index Modulated OFDM

open access: yesIEEE Access, 2018
We propose entropy coding-aided adaptive subcarrier-index-modulated orthogonal frequency division multiplexing (SIM-OFDM). In conventional SIM-OFDM, the indices of the subcarriers activated are capable of conveying extra information. We propose the novel

‘I'm still guessing what's happening and what I'm meant to do’: Special educator experiences of supporting echolalic students

open access: yesJournal of Research in Special Educational Needs, Volume 26, Issue 4, October 2026.
Abstract Echolalia has been widely examined in clinical and developmental research, yet the experiences of teachers, who arguably encounter echolalia across the widest variety of contexts and environments, remain largely unexplored. This study examined special education teachers lived experiences of echolalia in specialist schools.

Exploring Differences in Precision Agriculture Adoption: New and Beginning Farmers, and Established Farmers

open access: yesApplied Economic Perspectives and Policy, Volume 48, Issue 4, Page 970-983, September 2026.
ABSTRACT This paper compares precision agriculture (PA) adoption between new and beginning farmers (NBFRs) and established farmers using data from a 2021 U.S. Midwest farmer survey. We focus on the human capital of two different groups of farmers in the PA adoption.

Sustainable Productivity Growth in Agriculture: The Role of Shifts in R&D Investments and Technology

open access: yesApplied Economic Perspectives and Policy, Volume 48, Issue 4, Page 984-1004, September 2026.
ABSTRACT The objective of the paper is to evaluate the long‐term prospects of sustainable productivity growth linked to plausible assumptions on public agricultural R&D investments as the key productivity driver. Second, it investigates the role of changing R&D focus from yield maximization to input saving technologies (fertilizers and pesticides). The
