An Adaptive Neuron AQM for a Stable Internet [PDF]

, 2007
Recognizing that Internet congestion control is a complex nonlinear system, we propose here to use an intelligent controller to improve its stability and performance. In particular, we propose here a new, powerful, easy-to-configure and robust active queue management (AQM) scheme called adaptive neuron AQM (AN-AQM).

The Role of Moisture Transport Deficits in Modulating Drought and Fire Patterns in the Upper Paraguay River Basin, Brazil

Meteorological Applications, Volume 33, Issue 3, May/June 2026.
The Upper Paraguay River Basin faced intense droughts in 1999, 2007, and 2010, coinciding with extensive wildfires. In 2007, a severe drought episode affected 97.5% of its area. These extreme years were characterized by pronounced negative anomalies and shifts in atmospheric moisture contributions from key source regions, during dry season. ABSTRACT In

Unphysical Structure Collapse in Quantum Mechanics Calculations With Continuum Solvation

ChemPhysChem, Volume 27, Issue 5, 13 March 2026.
Quantum mechanics conformer searches with continuum solvation models yield preferably collapsed conformations not confirmed by sophisticated nuclear magnetic resonance (NMR) experiments. Continuum solvation force‐field and explicit solvation molecular dynamics simulations result preferably in stretched conformations, hinting on general weaknesses of ...

Fuzzy-Logic Based Active Queue Management Using Performance Metrics Mapping into Multi-Congestion Indicators

Cybernetics and Information Technologies, 2021
The congestion problem at the router buffer leads to serious consequences on network performance. Active Queue Management (AQM) has been developed to react to any possible congestion at the router buffer at an early stage.

Diversity of Terrestrial Malacofauna, Favorable Habitats, and Relationships With Mollusk Size in Urban Environments of Sergipe, Northeastern Brazil

Biotropica, Volume 58, Issue 2, March 2026.
The invasive exotic snail Achatina fulica dominates the terrestrial mollusk community in the city of Aracaju, occurring in all sampled urban habitats and being the most abundant species among the individuals collected. In addition, it exhibited a larger shell size and greater total weight, particularly in back gardens. ABSTRACT Terrestrial mollusks can

Coexistence of Takayasu Arteritis and Intestinal Tuberculosis in a Young Bangladeshi Woman

Clinical Case Reports, Volume 14, Issue 2, February 2026.
ABSTRACT Takayasu arteritis (TAK) is a rare, chronic, granulomatous large‐vessel vasculitis predominantly affecting young women. Although its etiology remains uncertain, tuberculosis (TB) has long been implicated as a potential trigger. We report a 28‐year‐old Bangladeshi woman with TAK coexisting with transverse colon TB, a rare but clinically ...
