Automated Bandwidth Selection for Inference in Linear Models With Time‐Varying Coefficients

open access: yesJournal of Time Series Analysis, EarlyView.
ABSTRACT The problem of selecting the smoothing parameter, or bandwidth, for kernel‐based estimators of time‐varying coefficients in linear models with possibly endogenous explanatory variables is considered. We examine automated bandwidth selection by means of cross‐validation, a nonparametric variant of Akaike's information criterion, and bootstrap ...

Difference independence of the Riemann zeta function

open access: yes, 2006
It is proved that the Riemann zeta function does not satisfy any nontrivial algebraic difference equation whose coefficients are meromorphic functions $\phi$ with Nevanlinna characteristic satisfying $T(r, \phi)=o(r)$ as $r\to \infty$Comment: To appear ...

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

open access: yesFEBS 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

open access: yesAdvanced 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 ...

Two-point correlation function for Dirichlet L-functions

open access: yes, 2013
The two-point correlation function for the zeros of Dirichlet L-functions at a height E on the critical line is calculated heuristically using a generalization of the Hardy-Littlewood conjecture for pairs of primes in arithmetic progression.

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

open access: yesAdvanced 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

open access: yesChemNanoMat, 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.

One‐Step Core‐Shell Structuring of Silicon Graphene Composite Anode Materials by Aqueous Reduced Graphene Oxide: Toward Practical Use of High‐Performance Lithium‐Ion Battery

open access: yesENERGY &ENVIRONMENTAL MATERIALS, Volume 9, Issue 1, January 2026.
The one‐step QrGO‐coating strategy ensures uniform encapsulation within an adhesive and conductive layer, addressing SiOx anode challenges. It mitigates cracking, enhances charge transport, and supports a high silicon content of 20 wt.%, surpassing commercial 5 wt.%. QrGO‐coated electrodes achieve superior capacity retention, with full cells delivering
