On the essential spectrum of the Laplacian and the drifted Laplacian
Journal of Functional Analysis, 2014 This paper concerns the $L^2$ essential spectrum of the Laplacian $ $ and the drift Laplacian $ _f$ on complete Riemannian manifolds endowed with a weighted measure $e^{-f}d\;vol_g$. We prove that the essential spectrum of the drift Laplacian $ _f$ is $[0,+\infty) $ provided the Bakry- mery curvature tensor $Ric_f$ is nonnegative and $f$ has ...

Analysis of the Laplacian of an incomplete manifold with almost polar boundary [PDF]
Rendiconti di Matematica e delle Sue Applicazioni, 2005 Motivated by recent interest in global analysis of singular manifolds, we establish the essential self-adjointness of a Laplacian, a Liouville property of subharmonic functions, conservativeness and parabolicity of an incomplete manifold.

More on Spectral Analysis of Signed Networks
Complexity, 2018 Spectral graph theory plays a key role in analyzing the structure of social (signed) networks. In this paper we continue to study some properties of (normalized) Laplacian matrix of signed networks. Sufficient and necessary conditions for the singularity

Zwitterionic Heavier Pnictinidenes in Redox Catalysis
Angewandte Chemie, EarlyView.Zwitterionic pnictinidenes: A new class of zwitterionic heavier pnictogen species stabilized by bis(N‐heterocyclic carbene)borate ligands is reported, enabling the isolation of Sb and Bi in multiple oxidation states. These thoroughly characterized systems exhibit cationic character and engage in redox catalysis, facilitating catalytic ...

Signless Laplacian energy of a first KCD matrix
Acta Universitatis Sapientiae: Informatica, 2022 The concept of first KCD signless Laplacian energy is initiated in this article. Moreover, we determine first KCD signless Laplacian spectrum and first KCD signless Laplacian energy for some class of graphs and their complement.

On distance matrices and Laplacians [PDF]
Linear Algebra and its Applications, 2005 The distance matrix \(D\) of a graph \(G\) of order \(n\) is the \(n\times n\) matrix with zeroes on the diagonal where the entries represent distances between pairs of vertices of \(G\). The authors extend a previous result for unweighted trees of \textit{R. L. Graham} and \textit{L. Lovász} [Adv. Math. 29, 60--88 (1978; Zbl 0382.05023)] and provide a

Advanced Science, EarlyView.This study developed an unsupervised radiomics system integrating CT imaging and multi‐omics data to stratify clear cell renal cell carcinoma into two subtypes with distinct clinical outcomes. Cluster 1 showed lower recurrence risk and active immunity, while Cluster 2 exhibited higher recurrence risk, enriched VHL/KDM5C mutations, immunosuppressive ...
