StorjLedger: An Innovative Distributed Storage Ecosystem That Overcomes Blockchain Trade‐Offs Using Erasure‐Coded Sharding and Proof‐of‐Storage Consensus

Engineering Reports, Volume 7, Issue 10, October 2025.
StorjLedger leverages erasure‐coded sharding and Proof‐of‐Storage to deliver nearly 1000 transactions per second with sub‐second latency, 98% data redundancy, and 76% lower storage costs, resolving the blockchain trilemma by harmonizing scalability, security, and decentralization.

Groups with triangle‐free graphs on p$p$‐regular classes

Mathematische Nachrichten, Volume 298, Issue 6, Page 1796-1807, June 2025.
Abstract Let p$p$ be a prime. In this paper, we classify the p$p$‐structure of those finite p$p$‐separable groups such that, given any three non‐central conjugacy classes of p$p$‐regular elements, two of them necessarily have coprime lengths.

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 ...

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.

Probability Hypothesis Density Filter‐Based Group Target Tracking Algorithm Using Rigid‐Body Similarity Model and Measurement Fusion: Implementations Across Random Finite Set Frameworks

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 ...

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$p$.

An elliptic curve test for Mersenne primes

, 2005
Let l ⩾ 3 be a prime, and let p = 2 l - 1 be the corresponding Mersenne number. The Lucas–Lehmer test for the primality of p goes as follows. Define the sequence of integers x k by the recursion x 0 = 4 , x k = x k - 1 2 - 2 .
