Solvability and Boundedness in Chemotaxis‐Consumption Models With Oppositely Acting Nonlocal Sources
Mathematical Methods in the Applied Sciences, Volume 49, Issue 14, Page 16146-16162, 30 September 2026.ABSTRACT In this paper, we investigate a chemotaxis system featuring a class of external source terms that incorporate both local and nonlocal growth as well as dampening effects. The model describes the evolution of a cell density u$$ u $$, which migrates in response to a chemical signal v$$ v $$, within an impermeable habitat.

Coupled Dynamics Between Networks and Fields in Physical Space: A Theoretical Perspective
Annalen der Physik, Volume 538, Issue 9, September 2026.Networks embedded in physical space often communicate through dynamical fields that both mediate and respond to collective behavior. A unified theoretical perspective is presented for these network‐field systems, linking established mathematical frameworks and revealing how feedback between discrete interactions and continuous spatial processes can ...

Cifrado de datos transmitidos a través de redes inalámbricas [PDF]
, 2013 Las redes inalámbricas tienen como característica principal, que no usan medios físicos (cables, fibra óptica, etc.) para funcionar. Esto es una gran ventaja, pero a la vez se convierte en una desventaja, ya que cualquier persona con un ordenador ...

Predicting the Toxicity of Chemical Compounds via Hyperdimensional Computing
Molecular Informatics, Volume 45, Issue 9, September 2026.Hyperdimensional computing converts text representations of chemical structures (SMILES) into high‐dimensional vectors. New compounds are classified by comparison with learned toxic and nontoxic reference patterns; across 12 Tox21 targets, overlapping four‐character SMILES patterns performed best among tested representations, supporting fast ...

Scanner‐agnostic artificial intelligence approach for fast bone scintigraphy
Journal of Applied Clinical Medical Physics, Volume 27, Issue 8, August 2026.Abstract Purpose Current bone scintigraphy protocols often demand full‐count, 10–15 min scans to preserve image quality, and existing deep‐learning (DL) denoisers typically need to be retrained or retuned for each camera manufacturer. We introduce a scanner‐agnostic adaptive‐diffusion U‐Net designed to reconstruct diagnostic‐grade images from half‐time
