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

Water 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.

Coset approach to the N=2 supersymmetric matrix GNLS hierarchies

, 1997
We discuss a large class of coset constructions of the N=2 sl(n|n-1) affine superalgebra. We select admissible subalgebras, i.e. subalgebras that induce linear chiral/antichiral constraints on the coset supercurrents.

Systems of Hess-Appel'rot type

, 2006
We construct higher-dimensional generalizations of the classical Hess-Appel'rot rigid body system. We give a Lax pair with a spectral parameter leading to an algebro-geometric integration of this new class of systems, which is closely related to the ...

Black Holes and Causal Structure in Anti-de Sitter Isometric Spacetimes [PDF]

, 1997
The observation that the 2+1 dimensional BTZ black hole can be obtained as a quotient space of anti-de Sitter space leads one to ask what causal behaviour other such quotient spaces can display.

The Matrix Product Approach to Quantum Spin Ladders [PDF]

, 1998
We present a manifestly rotational invariant formulation of the matrix product method valid for spin chains and ladders. We apply it to 2 legged spin ladders with spins 1/2, 1 and 3/2 and different magnetic structures labelled by the exchange coupling ...

New Middle Pleistocene Hominin Dental Remains From Velika Balanica, Serbia

American Journal of Biological Anthropology, Volume 188, Issue 2, October 2025.
ABSTRACT Objective The cave site of Velika Balanica in Sićevo Gorge, Serbia, has previously yielded early Neanderthal dental remains from Layer 3a, dated by thermoluminescence to 285 ± 34 and 295 ± 74 ka. We describe and compare four additional dental specimens recovered from the Middle Pleistocene Layers 3a and 3b of the cave: a right I1 (BH‐8), a ...

Variations in skin biophysical parameters with age, sex and breed in dogs

Veterinary Dermatology, Volume 36, Issue 5, Page 689-695, October 2025.
Background – Understanding the physiological and biophysical characteristics of skin provides information for developing appropriate management strategies for skin diseases. However, in dogs, variations in skin biophysical parameters, such as age, sex and breed, remain poorly understood.
