The matching polynomial of a distance-regular graph

International Journal of Mathematics and Mathematical Sciences, 2000
A distance-regular graph of diameter d has 2d intersection numbers that determine many properties of graph (e.g., its spectrum). We show that the first six coefficients of the matching polynomial of a distance-regular graph can also be determined from ...

Triangular fuzzy quadripartitioned neutrosophic set and its properties [PDF]

Neutrosophic Sets and Systems
The main objective of the paper is to hybridize the triangular fuzzy number and the quadripartitioned neutrosophic set and develop the triangular fuzzy quadripartitioned neutrosophic set.

Navigating new norms: a systematic review of factors for the development of effective digital tools in higher education

FEBS Open Bio, EarlyView.
What factors make for an effective digital learning tool in Higher Education? This systematic review identifies elements of a digital tool that published examples reveal to be features of an engaging and impactful digital tool. A systematic literature search yielded 25 research papers for analysis.

Self-intersection numbers of length-equivalent curves on surfaces [PDF]

, 2013
Two free homotopy classes of closed curves in an orientable surface with negative Euler characteristic are said to be length equivalent if for any hyperbolic structure on the surface, the length of the geodesic in one class is equal to the length of the ...

Intersection numbers of Riemann surfaces from Gaussian matrix models

, 2007
We consider a Gaussian random matrix theory in the presence of an external matrix source. This matrix model, after duality (a simple version of the closed/open string duality), yields a generalized Kontsevich model through an appropriate tuning of the ...

Virtual intersection numbers

, 2000
We attempt to present the intersection theory which is required to understand the work of Kontsevich and Manin. Finally, we repeat their computations of intersection numbers in a concrete example. To do so, we study the moduli stack M of stable maps of degree two from rational curves to $P^1$. We show that its Picard group is infinite cyclic.

Natural Products as Geroprotective Modulators in Diabetic Nephropathy: A Mechanistic Framework Integrating Aging Hallmarks and the AMPK–SIRT1–Nrf2 Axis

Aging and Cancer, EarlyView.
Natural products target the aging kidney in diabetic nephropathy by restoring the AMPK–SIRT1–Nrf2 axis, reducing oxidative stress, inflammation, fibrosis, and cellular senescence while enhancing mitochondrial biogenesis and antioxidant defenses.

Operators Based On Multiple Generalized Set-Valued Neutrosophic Quadruple Sets [PDF]

Neutrosophic Sets and Systems
In this study, as a generalized form of multiple valued neutrosophic numbers and neutrosophic quadruple numbers, multiple generalized set-valued neutrosophic quadruple numbers and sets are defined and their basic properties are given.

Reducing the number of fixed points of some homeomorphisms on nonprime 3-manifolds

Fixed Point Theory and Applications, 2006
We will consider the number of fixed points of homeomorphisms composed of finitely many slide homeomorphisms on closed oriented nonprime 3-manifolds. By isotoping such homeomorphisms, we try to reduce their fixed point numbers.
