Analysis of a Mathematical Model on the Dynamics of TB–HCV Coinfection With Medication

open access: yesJournal of Applied Mathematics, Volume 2026, Issue 1, 2026.
This study employs a deterministic model that describes the combined dynamics of TB and HCV aimed at determining the impact of medication in the management of TB–HCV coinfection. The analytical and numerical analyses indicate that if the TB–HCV coinfection effective reproduction number is less than unity, the absence of both TB and HCV infections ...

New variables of separation for particular case of the Kowalevski top

open access: yes, 2010
We discuss the polynomial bi-Hamiltonian structures for the Kowalevski top in special case of zero square integral. An explicit procedure to find variables of separation and separation relations is considered in detail.Comment: 11 pages, LaTeX with Ams ...

Control Node Placement and Structural Controllability of Water Quality Dynamics in Drinking Networks

open access: yesWater Resources Research, Volume 61, Issue 12, December 2025.
Abstract Chlorine, the most widely used disinfectant, needs to be adequately distributed in water distribution networks (WDNs) to maintain consistent residual levels and ensure safe water. This is performed through control node injections at the treatment plant and via booster stations distributed across the WDNs.

OD (order–disorder) interpretation and diffuse scattering analysis of an organic polytype with allotwin character: a detailed how‐to

open access: yesActa Crystallographica Section B, Volume 81, Issue 6, Page 550-564, December 2025.
The complex stacking disorder of 2,3‐dihydroxy‐1,3,4‐trimethyl‐6‐oxo‐1,4‐cyclohexadiene‐1‐carboxylic is analyzed by applying the order–disorder theory and its diffuse scattering is interpreted using a growth model.2,3‐Dihydroxy‐1,3,4‐trimethyl‐6‐oxo‐1,4‐cyclohexadiene‐1‐carboxylic acid crystallizes in an order–disorder (OD) structure with a high ...

On the Fibonacci universality classes in nonlinear fluctuating hydrodynamics

open access: yes, 2017
We present a lattice gas model that without fine tuning of parameters is expected to exhibit the so far elusive modified Kardar-Parisi-Zhang (KPZ) universality class.

The Gender Gap in Life Expectancy in the United States and Deaths of Despair: Trends From 1979 to 2022

open access: yesPopulation and Development Review, Volume 51, Issue 4, Page 1314-1342, December 2025.
Abstract The extent to which women outlive men in the United States has fluctuated over the 20th century, with periods of equalization, stagnation, and increase. Women's life expectancy advantage declined for roughly four decades but resurged after 2012.

Magnetoelectric ordering of BiFeO3 from the perspective of crystal chemistry

open access: yes, 2011
In this paper we examine the role of crystal chemistry factors in creating conditions for formation of magnetoelectric ordering in BiFeO3. It is generally accepted that the main reason of the ferroelectric distortion in BiFeO3 is concerned with a ...
