New Difference Triangle Sets by a Field‐Programmable Gate Array‐Based Search Technique
Journal of Combinatorial Designs, Volume 34, Issue 1, Page 37-50, January 2026.ABSTRACT We provide some difference triangle sets with scopes that improve upon the best known values. These are found with purpose‐built digital circuits realized with field‐programmable gate arrays (FPGAs) rather than software algorithms running on general‐purpose processors.

Mixer‐Based Neural Network for Binary Sequence Generation
Electronics Letters, Volume 62, Issue 1, January/December 2026.This paper proposes MixBinNet, a neural network‐based model for generating binary sequences with low autocorrelation sidelobes, low cross‐correlation and balanced bit distributions. By jointly optimizing these properties through custom loss functions, MixBinNet outperforms conventional chaotic map‐based methods, achieving improved correlation ...

Case Reports in Veterinary Medicine, Volume 2026, Issue 1, 2026.A 1‐year‐and‐9‐month‐old intact female Pembroke Welsh Corgi (10.5 kg) was referred for abdominal distension, intermittent diarrhea, and ascites. Abdominocentesis yielded 1200 mL of transudate (specific gravity, 1.008). Serum biochemistry showed hyperammonemia (NH3, 163 μg/dL), increased bile acids, and mild hypoalbuminemia.
