Multiderivative methods for periodic initial value problems [PDF]

open access: yes, 1982
A family of two-step multiderivative methods based on Pade approximants to the exponential function is developed. The methods are analysed and periodicity intervals in PECE mode are calculated.

Effects of Carbon‐to‐Nitrogen Ratio in Biofloc System on Water Quality, Growth Performance and Haematological Parameters of Nile Tilapia (Oreochromis niloticus)

open access: yesAquaculture, Fish and Fisheries, Volume 6, Issue 3, June 2026.
ABSTRACT A 10‐week indoor culture trial was carried out to assess the impact of various C/N ratios on the water quality, growth performance and haematology of Nile tilapia (Oreochromis niloticus) in a biofloc system. The experiment included four biofloc treatment groups with distinct C/N ratios (12:1, 15:1, 18:1 and 21:1) and a control group with a C/N

QCD Sum Rules study of meson-baryon sigma terms

open access: yes, 2008
The pion-baryon sigma terms and the strange-quark condensates of the octet and the decuplet baryons are calculated by employing the method of quantum chromodynamics (QCD) sum rules.

Unphysical Structure Collapse in Quantum Mechanics Calculations With Continuum Solvation

open access: yesChemPhysChem, 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 ...

SAM: Support Vector Machine Based Active Queue Management [PDF]

open access: yesMehran University Research Journal of Engineering and Technology, 2014
Recent years have seen an increasing interest in the design of AQM (Active Queue Management) controllers. The purpose of these controllers is to manage the network congestion under varying loads, link delays and bandwidth.

Reverse Engineering TCP/IP-like Networks using Delay-Sensitive Utility Functions [PDF]

open access: yes, 2007
TCP/IP can be interpreted as a distributed primal-dual algorithm to maximize aggregate utility over source rates. It has recently been shown that an equilibrium of TCP/IP, if it exists, maximizes the same delay-insensitive utility over both source ...

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

open access: yesBiotropica, 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
