Heat Kernel and Green Kernel Comparison Theorems for Infinite Graphs
, 1997 For an infinite graph, general lower and upper estimates of the Green kernel and the heat kernel are given. The estimates are optimal in the case of the homogeneous regular trees.

Enhanced Stability in Zero‐Excess Li‐Metal Batteries via Prelithiated Carbon Nanofiber Interlayers
Advanced Science, EarlyView.Carbon nanofibers carbonized at 700°C show Li metal deposition predominantly on the side facing the Cu current collector. During delithiation, Li agglomerates remain as inactive lithium on the fiber surface. This behavior can be changed by a modified n‐Buli prelithiation without a washing step, suppressing dead Li formation and therefore enabling ...

Heat kernel methods for multiloop calculations in curved spacetime: nonzero spin
Journal of High Energy PhysicsIn a previous paper we have presented a general formalism for computing Feynman diagrams for scalar fields in curved spacetime at any loop order using heat kernel methods.

Neuromorphic Near‐Sensor and In‐Sensor Computing Enabled by Next‐Generation Material‐Based Sensors
Advanced Science, EarlyView.This Review presents a structural framework that classifies neuromorphic sensing into near‐sensor and in‐sensor architectures, clarifying physical coupling between sensing and computation. The framework connects neural and synaptic device functions with recent advances in optical, mechanical, and chemical sensing, compares energy consumption and ...

Diagrams for heat kernel expansions
A diagramatic heat kernel expansion technique is presented. The method is especially well suited to the small-derivative expansion of the heat kernel, but it can also be used to reproduce the results obtained by the approach known as covariant ...

PlantGFM: A Genomic Foundation Model for Discovery and Creation of Plant Genes
Advanced Science, EarlyView.A plant genomic foundation model pre‐trained on 12 species enables both accurate gene prediction and de novo gene design. Through AI‐human knowledge screening, seven designed sequences showed transcriptional activity in plants, with two expressing stable proteins—demonstrating the first DNA‐RNA‐protein expression of LLM‐generated genes in plants and ...

The Parametrix Construction of the Heat Kernel on a Graph
In this paper we develop the parametrix approach for constructing the heat kernel on a graph G. In particular, we highlight two specific cases. First, we consider the case when G is embedded in a Euclidean domain Ω, and we use a heat kernel associated to

Discrete Heat Kernel Estimates on Inner Uniform Domains
, 2018 We prove a variety of estimates for the heat kernel on domains with discrete space and discrete time. First, we give a novel proof of the fact that, for a fixed graph $G$ with heat semigroup generator $P$ and measure $m$, the following are equivalent: (1)
