The Renyi redundancy of generalized Huffman codes [PDF]

IEEE Transactions on Information Theory, 1988
If optimality is measured by average codeword length, Huffman's algorithm gives optimal codes, and the redundancy can be measured as the difference between the average codeword length and Shannon's entropy. If the objective function is replaced by an exponentially weighted average, then a simple modification of Huffman's algorithm gives optimal codes ...

AI Agent for Hydrologic Modeling: Definition, Development, and Application

Geophysical Research Letters, Volume 53, Issue 13, 16 July 2026.
Abstract Hydrologic modeling supports flood forecasting and water resources management, but complex preprocessing, parameterization, and configuration limit broader use. This study defines a six‐level framework for artificial intelligence (AI)‐agent autonomy in hydrologic modeling and develops a Level‐4 agent, powered by large language models, that ...

3D Water Vapor Signature of Tropical Storms: GNSS Tomography of the 10 Most Severe Rainfall Events in Hong Kong 2015–2025

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 13, 16 July 2026.
Abstract Monitoring water vapor during extreme events is crucial for understanding atmospheric physics, as well as for improving the prediction of severe weather and enhancing early warning systems. The major gap in monitoring water vapor during extreme events lies in the limited spatial and temporal resolutions of existing techniques.

Extensive but fragmented evidence limits understanding of factors shaping farmers' decisions regarding diversified farming systems: A global evidence map

People and Nature, Volume 8, Issue 7, Page 2212-2232, July 2026.
Abstract Diversified farming systems are increasingly recognised for their potential to enhance the sustainability and resilience of food systems. Yet it remains unclear whether empirical research adequately captures the drivers and constraints shaping farmers' decisions regarding diversified farming systems across stages of decision‐making ...

Iterative Construction of Reversible Variable-Length Codes and Variable-Length Error-Correcting Codes

, 2004
We propose a generic algorithm for the construction of efficient reversible variable-length codes (RVLCs) and variable-length error-correcting (VLEC) codes, which optimizes the codeword length distribution.
