(Wiley, 2025)Hedysarum species play a crucial agronomic role due to their high feed quality and ability to enhance soil fertility through nitrogen fixation. Traditionally, they have been used in medicine to boost energy, support the ... -
Investigation of fractional order genesio-tesi system using laplace transformation
(Springer, 2025)In this paper the fractional-order Genesio-Tesi chaotic system is investigated with Laplace transformation method. Genesio-Tesi system is a three-dimensional equation system with quadratic nonlinearity and is frequently ... -
Soliton solutions associated with a class of third-order ordinary linear differential operators
(Wiley, 2025)Explicit solutions to the related integrable nonlinear evolution equations are constructed by solving the inverse scattering problem in the reflectionless case for the third-order differential equation (Formula presented.), ... -
Finite dimensional distributions for short incomplete Gauss sums
(Academic Press Inc., 2025)This paper investigates an equivalent principle to the weak invariance principle, with a focus on short incomplete Gauss sums. We establish a limit law for the finite-dimensional distributions (FDD) of these sums as the ... -
Multi-sensor data fusion based on the similarity measure and belief (Deng) entropy under neutrosophic evidence sets
(American Institute of Mathematical Sciences, 2025)The Dempster–Shafer evidence theory is a very practical concept for handling uncertain information. The foundation of this theory lies in the basic probability assignment (BPA), which exclusively accounts for the degree ... -
An efficient ultrasound-assisted rapid synthesis of 6-bromo-2-substituted-3H-imidazo[4,5-b]pyridine derivatives and their studies on AChE and urease inhibition
(Springer, 2025)A rapid and practical protocol was developed for synthesizing 6-bromo-2-substituted-3H-imidazo[4,5-b]pyridine derivatives under ultrasound irradiation for the first time. The protocol employs iminoester hydrochloride, which ... -
Compatible congruences defined via triangular norms and triangular conorms
(Taylor & Francis Group, 2025)The main aim of this paper is to investigate relationship between ideals or filters of a bounded lattice and T-compatible or S-compatible congruences which are obtained by using the definition of compatible aggregation ... -
Synthesis of novel thiazole/thiadiazole conjugates of fluoroquinolones as potent antibacterial and antimycobacterial agents
(Wiley, 2025)Twenty azole-fluoroquinolone hybrids were designed and synthesized by conjugating thiazole and thiadiazole structures to ciprofloxacin and norfloxacin via a 2-oxoethyl bridge. The structures and purities of the synthesized ... -
