Severe Heart Failure Associated With Tachycardia-Induced Cardiomyopathy Due to Incessant Atrioventricular Re-Entrant Tachycardia

JACC: Case Reports, 2021
Short RP interval atrioventricular re-entrant tachycardias do not typically present as an incessant form. We present 2 cases of incessant atrioventricular re-entrant tachycardias leading to tachycardia-induced cardiomyopathy with severe heart failure ...

IMPACT DYNAMIC BEHAVIOR ANALYSIS OF MULTIPLE LAYERS RE-ENTRANT HONEYCOMB CYLINDRICAL SHELLS (MT)

Jixie qiangdu, 2023
The single layer re-entrant honeycomb cylindrical shell with different angles is established in this paper. Based on the single layer re-entrant honeycomb cylindrical shell with different angles, a novel composite re-entrant honeycomb cylindrical shell ...

Dynamics of cavity structures and wall-pressure fluctuations associated with shedding mechanism in unsteady sheet/cloud cavitating flows

Flow, 2023
The physics and mechanism of sheet/cloud cavitation in a convergent–divergent channel are investigated using synchronized dynamic surface pressure measurement and high-speed imaging in a water tunnel to probe the cavity shedding mechanism.

Modeling and Analysis of Material Flows in Re-Entrant Supply Chain Networks Using Modified Partial Differential Equations

Journal of Applied Mathematics, 2011
The basic partial differential equation (PDE) models for supply chain networks with re-entrant nodes and their macroscopic are proposed. However, through numerical examples, the basic continuum models do not perform well for multiple re-entrant systems ...

Heuristic based genetic algorithms for the re-entrant total completion time flowshop scheduling with learning consideration

International Journal of Computational Intelligence Systems, 2016
Recently, both the learning effect scheduling and re-entrant scheduling have received more attention separately in research community. However, the learning effect concept has not been introduced into re-entrant scheduling in the environment setting.

Punching shear in flat slabs with re-entrant corner columns [PDF]

Revista IBRACON de Estruturas e Materiais
Studies on slab-column connections supported on re-entrant corners are limited. Although design standards generally provide detailed guidelines for internal, edge, and corner connections, re-entrant corner connections are overlooked in these standards ...

Possible re-entrant superconductivity in EuFe2As2 under pressure [PDF]

, 2008
We studied the temperature-pressure phase diagram of EuFe2As2 by measurements of the electrical resistivity. The antiferromagnetic spin-density-wave transition at T_0 associated with the FeAs-layers is continuously suppressed with increasing pressure ...

Re-entrant resonant tunneling

, 1996
We study the effect of electron-electron interactions on the resonant-tunneling spectroscopy of the localized states in a barrier. Using a simple model of three localized states, we show that, due to the Coulomb interactions, a single state can give rise
