A note on the dynamical zeta function of general toral endomorphisms

, 2009
It is well-known that the Artin-Mazur dynamical zeta function of a hyperbolic or quasi-hyperbolic toral automorphism is a rational function, which can be calculated in terms of the eigenvalues of the corresponding integer matrix.

Experimental Analysis and Physics‐Based Analytical Model on Twisted and Coiled Artificial Muscles

Advanced Engineering Materials, Volume 28, Issue 2, January 21, 2026.
Twisted and coiled artificial muscles made from silver‐coated nylon fibers are investigated through experiments and analytical modeling. The actuators achieve contractions up to 19.3% and specific work of 8 kJ kg−1, though efficiency remains limited (≈0.15%) by thermal losses.

A unified model for Duchenne muscular dystrophy gene involvement in cancer: context‐dependent tumour suppression and oncogenicity

FEBS Open Bio, Volume 16, Issue 1, Page 222-236, January 2026.
We propose a context‐dependent model where the Duchenne muscular dystrophy (DMD) gene acts as a tumour suppressor in aggressive tumours and as an oncogene in less aggressive ones. We propose this model as a unified framework to explain the opposing survival associations with DMD expression and to guide experimental exploration of the dual role of DMD ...

A Dynamic DNA Nano‐Antioxidant Targeting Galectin‐3 Attenuates Liver Fibrosis via Reducing Macrophage Oxidative Stress

Advanced Science, Volume 13, Issue 4, 19 January 2026.
This study developed a dynamic DNA nano‐antioxidant (DDN) for Galectin‐3 siRNA delivery, specifically targeting hepatic macrophages to suppress ROS‐driven fibrosis. DDN enhanced hepatic accumulation, restored NRF2 signaling, and attenuated oxidative stress, collagen deposition, and fibrotic progression in a CCl4‐induced cirrhosis model, demonstrating ...

Representation Growth of Linear Groups

, 2008
Let $\Gamma$ be a group and $r_n(\Gamma)$ the number of its $n$-dimensional irreducible complex representations. We define and study the associated representation zeta function $\calz_\Gamma(s) = \suml^\infty_{n=1} r_n(\Gamma)n^{-s}$. When $\Gamma$ is an

DFT‐Based Insights Into Elastic, Thermophysical, Electronic, and Optical Properties of Topological Insulators XTe5 (X = Zr, Hf)

Advanced Physics Research, Volume 5, Issue 1, January 2026.
In this work, we present the first in‐depth investigation of elasto‐mechanical, thermophysical, and optical properties of these compounds. In particular, we analyzed the directional dependence of the elastic properties, explored the optical response for different photon polarization directions, and examined potential industrial applications of these ...

Theoretical Design and Characterization of Rb2ZnRuCl6 and Cs2ZnRuCl6 Novel Halide Perovskites

ChemNanoMat, Volume 12, Issue 1, January 2026.
Lead‐free Ru‐based double halide perovskites Rb2ZnRuCl6 and Cs2ZnRuCl6 are theoretically predicted to be structurally stable. Their Ru‐Cl‐dominated electronic structure yields indirect bandgaps in the visible range and moderate dielectric screening, favoring efficient photoexcited charge generation and separation for optoelectronic applications.

The Intersection of Two Fermat Hypersurfaces in P^3 via Computation of Quotient Curves [PDF]

, 2010
We study the intersection of two particular Fermat hypersurfaces in $\mathbb{P}^3$ over a finite field. Using the Kani-Rosen decomposition we study arithmetic properties of this curve in terms of its quotients.

On the number of n-dimensional representations of SU(3), the Bernoulli numbers, and the Witten zeta function

, 2015
We derive new results about properties of the Witten zeta function associated with the group SU(3), and use them to prove an asymptotic formula for the number of n-dimensional representations of SU(3) counted up to equivalence.
