On Regular Quaternary Hadamard Matrices

Journal of Combinatorial Designs, Volume 34, Issue 5, Page 215-227, May 2026.
ABSTRACT Through the use of regularizing vectors, all regular quaternary Hadamard matrices of orders 10 and 18 have been successfully identified. Of these, two matrices of order 10 and 184 matrices of order 18 were found to have unbiased mates. Converting the quaternary Hadamard matrices of order 18 to real Hadamard matrices, the study uncovered that ...

Madden‐Julian Oscillation and Atmospheric Rivers: New Insights on Water Source and Transport for Extreme Rainfall Over the Western U.S.

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 6, 28 March 2026.
Abstract Atmospheric rivers (ARs) were first documented by Zhu and Newell for transporting global water vapor. ARs contribute to extreme rainfall, especially over the Western United States. The primary water vapor source of ARs is from the tropical ocean, where convective systems bring the moist flux upward from the surface to the troposphere. Previous

Indo–Western Pacific Tropical Heating Anomalies Regulate the Cross‐Pacific Atmospheric River Highways During Boreal Summer

Geophysical Research Letters, Volume 53, Issue 5, 16 March 2026.
Abstract Atmospheric rivers (ARs) constitute a global, interconnected highway network rather than isolated regional events. In boreal summer, cross‐Pacific ARs originate over Southeast Asia, are fueled by subtropical outflows from the Asian monsoon plume, transport warm, moist air across the North Pacific, and make landfall in North America (NA).

A Review of Classical Lossless Data Compression Algorithmsand Their Contemporary Relevance [PDF]

Biuletyn Wojskowej Akademii Technicznej
Compression is data processing aimed at reducing the amount of information (e.g., for archiving and transfer). There is lossyand lossless compression. Compression algorithms can be either general-purpose or designed for specific types of data (e.g., for ...

Validating Dental Histology for Perinatal Age Estimation Using Human Deciduous Teeth

American Journal of Biological Anthropology, Volume 189, Issue 3, March 2026.
ABSTRACT Objectives This study tests the accuracy of dental histology for perinatal age estimation using deciduous teeth from modern human infants of known age. We evaluate whether enamel and dentin incremental structures, particularly the Neonatal Line (NNL), can be used to provide a reliable estimate of chronological age.

A new lossless method of Huffman coding for text data compression and decompression process with FPGA implementation [PDF]

, 2016
Digital compression for reducing data size is important because of bandwidth restriction. Compression technique is also named source coding. It defines the process of compressed data using less number of bits than uncompressed form.

Time Preferences, Financial Self‐Efficacy, and Financial Literacy: Relationships With Financial Well‐Being Indicators

FINANCIAL PLANNING REVIEW, Volume 9, Issue 1, March 2026.
ABSTRACT This study investigates the relationships between individual preferences, personality traits, abilities, and multiple indicators of financial well‐being (FWB). Employing survey data from the Understanding America Study (UAS), we analyze FWB across its different dimensions, including a composite scale, single‐item perceptions of FWB, objective ...
