The Critical Group of a Line Graph [PDF]

Annals of Combinatorics, 2012
The critical group of a graph is a finite abelian group whose order is the number of spanning forests of the graph. This paper provides three basic structural results on the critical group of a line graph. The first deals with connected graphs containing no cut-edge. Here the number of independent cycles in the graph, which is known to bound the number

Multi-Criteria-Based Key Transmission Section Identification and Prevention–Emergency Coordinated Optimal Control Strategy

Energies
Large-scale blackouts in power systems are often triggered by weak links susceptible to cascading failures. As the concentrated reflection of the system’s weak links, identifying key transmission sections and further implementing safety control measures ...

Bronchoscopic Lung Volume Reduction

Pulmonary Medicine, 2011
The application of lung volume reduction surgery in clinical practice is limited by high postoperative morbidity and stringent selection criteria. This has been the impetus for the development of bronchoscopic approaches to lung volume reduction.

TESTING OF JEROVEC SAND AND DEFINING ITS CRITICAL STATE LINE [PDF]

e-GFOS, 2017
The behavior of sand largely depends on the initial state, water content, drainage conditions, and type of action on the sand. The dominant mechanism that governs sand behavior is dilatancy, the volume change during shearing.

Dislocations and the critical endpoint of the melting line of vortex line lattices

, 1999
We develop a theory for dislocation-mediated structural transitions in the vortex lattice which allows for a unified description of phase transitions between the three phases, the elastic vortex glass, the amorphous vortex glass, and the vortex liquid ...

Takotsubo's Cardiomyopathy in a Young Female with Severe Traumatic Brain Injury: A Case Report

Journal of Neuroanaesthesiology and Critical Care
Takotsubo's cardiomyopathy (TC) typically presents with acute cardiac dysfunction due to regional wall motion abnormality, but unlike other cardiac pathologies, it recovers within a short period.

The expected number of critical percolation clusters intersecting a line segment [PDF]

, 2015
We study critical percolation on a regular planar lattice. Let $E_G(n)$ be the expected number of open clusters intersecting or hitting the line segment $[0,n]$. (For the subscript $G$ we either take $\mathbb{H}$, when we restrict to the upper halfplane,
