Applying Generalized Joint Attribute Modeling to Select Local Indicator Fish Species for River Management

Ecological Research, Volume 41, Issue 2, March 2026.
We propose an approach that employs generalized joint attribute modeling (GJAM) to select local indicator species. We examined whether GJAM has the potential to select local indicator species using data on water environmental factors and fish densities in two rivers in Kanagawa Prefecture, Japan. ABSTRACT To protect local ecosystem and biodiversity, it

Computing Wiener and Hyper-Wiener Indices of Zero-Divisor Graph of ℤℊ3×ℤI1I2

Journal of Function Spaces, 2022
Let S=ℤℊ3×ℤI1I2 be a commutative ring where ℊ,I1 and I2 are positive prime integers with I1≠I2. The zero-divisor graph assigned to S is an undirected graph, denoted as YS with vertex set V(Y(S)) consisting of all Zero-divisor of the ring S and for any c,

Global Research Trends and Hotspots in Cerebral Small Vessel Disease‐Related Cognitive Impairment: A Bibliometric Analysis (2001–2024)

Brain and Behavior, Volume 16, Issue 1, January 2026.
This bibliometric study systematically analyzed 1074 publications in the field of CSVD‐CI from 2001 to 2024. The research reveals three evolutionary phases and identifies four core research clusters: pathophysiological mechanisms, neuroimaging biomarkers, clinical assessment, and therapeutic interventions.

Algorithms for Two Types of Topological Indices

Algorithms
Topological indices are closely related to the stability and physical properties (such as the boiling point) of chemical molecules. The permanental sum and Hosoya index are two topological indices that are strongly associated with molecular structure. In

On the Wiener complexity and the Wiener index of fullerene graphs

, 2019
Fullerenes are molecules in the form of cage-like polyhedra, consisting solely of carbon atoms. Fullerene graphs are mathematical models of fullerene molecules. The transmission of a vertex $v$ of a graph is the sum of distances from $v$ to all the other

Dual Proximal Groups Concisely Representing Complex Hosoya Triangles

Advances in Mathematical Physics, Volume 2026, Issue 1, 2026.
This paper introduces dual proximal groups (DPGs) that provide concise representation of complex Hosoya triangles (CHTs). An application is given in terms of the DPG representation of collections of Hosoya‐Hilbert circular triangles on modulated motion waveforms in sequences of video frames. MSC2020 Classification: 11B39,54E05,57S25.
