On the Diamond Bessel Heat Kernel [PDF]

open access: yesJournal of Applied Mathematics, 2011
We study the heat equation in n dimensional by Diamond Bessel operator. We find the solution by method of convolution and Fourier transform in distribution theory and also obtain an interesting kernel related to the spectrum and the kernel which is ...

Local clustering via approximate heat kernel PageRank with subgraph sampling [PDF]

open access: yesScientific Reports, 2021
Graph clustering, a fundamental technique in network science for understanding structures in complex systems, presents inherent problems. Though studied extensively in the literature, graph clustering in large systems remains particularly challenging ...

A note on heat kernel of graphs. [PDF]

open access: yesHeliyon
Consider a simple undirected connected graph G, with D ( G ) and A ( G ) representing its degree and adjacency matrices, respectively. Furthermore, L ( G ) = D ( G ) - A ( G ) is the Laplacian matrix of G, and H t = exp ⁡ ( - t L ( G ) ) is the heat kernel (HK) of G, with t > 0 denoting the time variable.

Diameter Estimate in Geometric Flows

open access: yesMathematics, 2023
We prove the upper and lower bounds of the diameter of a compact manifold (M,g(t)) with dimRM=n(n≥3) and a family of Riemannian metrics g(t) satisfying some geometric flows. Except for Ricci flow, these flows include List–Ricci flow, harmonic-Ricci flow,

Responses of Physiological Traits and Grain Yield to Short Heat Stress during Different Grain-Filling Stages in Summer Maize

open access: yesAgronomy, 2023
Maize kernel growth is sensitive to heat stress, which is predicted to result in yield loss. However, the response of maize to short-term heat stress during different kernel-growth stages is still not clear.

Pointwise monotonicity of heat kernels [PDF]

open access: yesRevista Matemática Complutense, 2021
AbstractIn this paper we present an elementary proof of a pointwise radial monotonicity property of heat kernels that is shared by the Euclidean spaces, spheres and hyperbolic spaces. The main result was discovered by Cheeger and Yau in 1981 and rediscovered in special cases during the last few years.

Computational modeling of spatial variation in moisture content and temperature distribution in corn at different superheated steam temperatures

open access: yesCogent Engineering, 2023
The Superheated steam has been shown to be more effective than hot air for drying corn. Modeling studies have been carried out in fluidized bed dryers to determine the moisture and heat transfer characteristics of corn, but there are no modeling studies ...
