Variable‐Range Hopping Conduction in Amorphous, Non‐Stoichiometric Gallium Oxide
Advanced Electronic Materials, Volume 11, Issue 4, April 2025.The combination of experimental evidence, ab‐initio DOS calculations and quantitative modeling by kinetic Monte Carlo simulations reveals: Variable‐range hopping (VRH) is the dominant electron conduction mechanism in a‐GaOx (x = 0.8 to 1.0), even at room temperature, which leads to a new, fundamental understanding of a‐GaOx‐based electronic devices ...

Communications in Advanced Mathematical SciencesThis paper introduces an axiomatic approach in the theory of energy dissipation in Hilbert envelopes on motion waveforms emanating from various vibrating dynamical systems. A Hilbert envelope is a curve tangent to peak points on a motion waveform.

A characterization of some finite simple groups by their character codegrees
Mathematische Nachrichten, Volume 298, Issue 4, Page 1356-1369, April 2025.Abstract Let G$G$ be a finite group and let χ$\chi$ be a complex irreducible character of G$G$. The codegree of χ$\chi$ is defined by cod(χ)=|G:ker(χ)|/χ(1)$\textrm {cod}(\chi)=|G:\textrm {ker}(\chi)|/\chi (1)$, where ker(χ)$\textrm {ker}(\chi)$ is the kernel of χ$\chi$.

Batched ranged random integer generation
Software: Practice and Experience, Volume 55, Issue 1, Page 155-169, January 2025.Summary Pseudorandom values are often generated as 64‐bit binary words. These random words need to be converted into ranged values without statistical bias. We present an efficient algorithm to generate multiple independent uniformly‐random bounded integers from a single uniformly‐random binary word, without any bias.

IET Radar, Sonar &Navigation, Volume 19, Issue 1, January/December 2025.This paper proposes an improved group target tracking algorithm based on rigid‐body similarity model and measurement fusion, implemented across different random finite set filtering frameworks. The method outperforms traditional VLFM algorithms in the GMPHD framework and demonstrates robustness against varying clutter densities in the PMBM framework ...

Perfect and Mersenne Numbers [PDF]
, 2019 U ovom radu proučavamo Mersenneove i savršene brojeve. Kažemo da je prirodan broj N savršen ako je σ(N) = 2N, gdje je σ(N) suma pravih djelitelja broja N.

Weakly subnormal subgroups and variations of the Baer–Suzuki theorem
Journal of the London Mathematical Society, Volume 111, Issue 1, January 2025.Abstract A subgroup R$R$ of a finite group G$G$ is weakly subnormal in G$G$ if R$R$ is not subnormal in G$G$ but it is subnormal in every proper overgroup of R$R$ in G$G$. In this paper, we first classify all finite groups G$G$ that contains a weakly subnormal p$p$‐subgroup for some prime p$p$.

IET Image Processing, Volume 18, Issue 13, Page 4189-4206, 13 November 2024.This research work presents a novel secured spatial steganography algorithm consisting of three stages. In the first stage, a secret message is divided into three parts, each is encrypted using a tan logistic map encryption key with a unique seed value.
