Infinite Families of Gauge-Equivalent $R$-Matrices and Gradations of Quantized Affine Algebras

, 1994
Associated with the fundamental representation of a quantum algebra such as $U_q(A_1)$ or $U_q(A_2)$, there exist infinitely many gauge-equivalent $R$-matrices with different spectral-parameter dependences.

Associations Between APOE Genotypes and Vascular Pathology Lesions in Alzheimer's Disease: Insights from the NACC Dataset

Alzheimer's &Dementia, Volume 21, Issue S1, December 2025.
Abstract Background Alzheimer's disease (AD) is known as a progressive neurodegenerative disorder. Evidence suggest that Apolipoprotein E (APOE) plays a significant role with AD, but only limited work has examined APOE relationships with vascular pathology lesions in the brain. The objective here is to investigate the association between APOE genotypes

Bound - states for truncated Coulomb potentials

, 2000
The pseudoperturbative shifted - $l$ expansion technique PSLET is generalized for states with arbitrary number of nodal zeros. Bound- states energy eigenvalues for two truncated coulombic potentials are calculated using PSLET.

Hierarchical analysis of spreading dynamics in complex systems

Computer-Aided Civil and Infrastructure Engineering, Volume 40, Issue 31, Page 6223-6241, 29 December 2025.
Abstract Modeling spreading dynamics on spatial networks is crucial to addressing challenges related to traffic congestion, epidemic outbreaks, efficient information dissemination, and technology adoption. Existing approaches include domain‐specific agent‐based simulations, which offer detailed dynamics but often involve extensive parameterization, and

Twisted Quantum Affine Superalgebra $U_q[sl(2|2)^{(2)}]$, $U_q[osp(2|2)]$ Invariant R-matrices and a New Integrable Electronic Model

, 1996
We describe the twisted affine superalgebra $sl(2|2)^{(2)}$ and its quantized version $U_q[sl(2|2)^{(2)}]$. We investigate the tensor product representation of the 4-dimensional grade star representation for the fixed point subsuperalgebra $U_q[osp(2|2)]$

Manipulating the Chiral Self‐Assembly of Achiral Porphyrin Molecules with Carbon Nanotubes as Templates

Advanced Materials Interfaces, Volume 12, Issue 21, November 10, 2025.
A chiral self‐assembly of achiral porphyrin molecules is presented on the surfaces of achiral carbon nanotubes, and the obvious optical activity is observed as direct and solid spectroscopic evidence. The findings provide an effective carbon nanotube‐templated strategy for inducing and manipulating the chiral self‐assembly of porphyrin and other chiral/

Agricultural Financing and Unemployment Rate in Nigeria: A Cointegration Approach

Acta Universitatis Sapientiae: Economics and Business, 2020
In Nigeria, the level of agricultural productivity and farmers’ income have been affected by inadequate financing, which invariably discourages job creation and increases unemployment rate.
