A characterization of some finite simple groups by their character codegrees

open access: yesMathematische 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$\chi$.

Multiscale Stochastic Modeling of Backward Erosion Piping Initiation, From Grain Kinetics to Weibull Statistics. Part I: Analytical Derivations

open access: yesInternational Journal for Numerical and Analytical Methods in Geomechanics, Volume 49, Issue 4, Page 1262-1277, March 2025.
ABSTRACT Backward erosion piping (BEP) is a significant contributor to failures in global flood protection infrastructure, yet it remains among the least understood geotechnical phenomena, particularly concerning the fundamental mechanisms driving its initiation.

Silicon single-electron random number generator based on random telegraph signals at room temperature

open access: yesAIP Advances, 2020
The need for hardware random number generators (HRNGs) that can be integrated in a silicon (Si) complementary-metal–oxide–semiconductor (CMOS) platform has become increasingly important in the era of the Internet-of-Things (IoT).

Grading of diabetic retinopathy using a pre‐segmenting deep learning classification model: Validation of an automated algorithm

open access: yesActa Ophthalmologica, Volume 103, Issue 2, Page 215-221, March 2025.
Abstract Purpose To validate the performance of autonomous diabetic retinopathy (DR) grading by comparing a human grader and a self‐developed deep‐learning (DL) algorithm with gold‐standard evaluation. Methods We included 500, 6‐field retinal images graded by an expert ophthalmologist (gold standard) according to the International Clinical Diabetic ...

Generalized New Mersenne Number Transforms

open access: yesIEEE Transactions on Signal Processing, 2012
Two new number theoretic transforms named as odd and odd-squared new Mersenne number transforms are introduced for incorporation into a generalized new Mersenne number transforms (GNMNTs) suite, which are defined in finite fields modulo Mersenne primes where arithmetic operations and residue reductions are simple to implement. This suite is categorized

On generalized Mersenne hybrid numbers

open access: yesAnnales Universitatis Mariae Curie-Sklodowska, sectio A – Mathematica, 2020
The hybrid numbers are generalization of complex, hyperbolic and dual numbers. In this paper we consider  a special kind of hybrid numbers, namely the Mersenne hybrid numbers and we give some of their properties.

Development and validation of a deep learning model for morphological assessment of myeloproliferative neoplasms using clinical data and digital pathology

open access: yesBritish Journal of Haematology, Volume 206, Issue 2, Page 596-606, February 2025.
The subjectivity of morphological assessment and the overlapping pathological features of different subtypes of myeloproliferative neoplasms (MPNs) make accurate diagnosis challenging. To improve the pathological assessment of MPNs, we took both haematoxylin–eosin staining BM whole‐slide images (WSI) and clinical features from 1051 MPN and non‐MPN ...

Risk analysis of the economic viability of feedlot aberdeen angus steers fed with different proportions of concentrate

open access: yesBioscience Journal, 2017
The economic viability of feedlot Aberdeen Angus steers fed with diets composed of different concentrate levels (CL) in dry matter (25, 40, 55 or 70%) was estimated using Monte Carlo simulation combined with Spearman rank correlation, considering nine ...

Dimorphic Mersenne numbers and their applications

open access: yes, 2022
The Mersenne primes are primes which can be written as some prime power of 2 minus 1. These primes were studied from antiquity in that their close connection with perfect numbers and even to present day in that their easiness for primality test. In this paper, we introduce the dimorphic Mersenne numbers as a degenerate version of the Mersenne numbers ...
