Factors affecting basket catheter detection of real and phantom rotors in the atria: A computational study
2018
[EN] Anatomically based procedures to ablate atrial fibrillation (AF) are often successful in terminating paroxysmal AF. However, the ability to terminate persistent AF remains disappointing. New mechanistic approaches use multiple-electrode basket catheter mapping to localize and target AF drivers in the form of rotors but significant concerns remain about their accuracy. We aimed to evaluate how electrode-endocardium distance, far-field sources and inter-electrode distance affect the accuracy of localizing rotors. Sustained rotor activation of the atria was simulated numerically and mapped using a virtual basket catheter with varying electrode densities placed at different positions withi…
ADT implementation and completion by induction from examples
1991
There exists a fast algorithm [2] for inductive synthesis of terminating and ground confluent term rewriting systems from samples. The principles of this algorithm and the methodology of its use for implementation and completion of abstract data types are described.
Large area strip edgeless detectors fabricated by plasma etching process
2007
This work presents the last results from large area edgeless detector, fabricated by Plasma Etching Process to reduce the conventional width of the terminating structure of position sensitive detectors to the detector rim.. A current terminating ring is used to decouple the electrical behavior of the surface from the sensitive volume within a few tens of micrometers. The detectors have been illuminated using an infrared laser and their surface scanned in order to understand their collection behavior at the cut edge. The detectors have very high efficiency up to the insensitive area which is located about 60 mum from the detector edge.
Search for the terminating27−state inNd140
2015
In the search for the fully aligned 27(-) state in Nd-140 predicted by cranked Nilsson-Strutinsky calculations, new close-to-spherical high-spin states have been discovered. Both the close-to-spherical and the triaxial calculated states are in good agreement with the experimental results, supporting the existence of shape coexistence up to very high spins. Shell-model calculations using a newly developed effective interaction for the 50 <= N, Z <= 82 mass region are in good agreement with the observed spherical states. The comparison between the experimental and calculated level energies allowed the relative energy to be established between several proton and neutron orbitals at high energy…
TERMINATING STATES IN Z = 71Lu NUCLEI WITH N ≈ 90
2010
The high-spin yrast states in 161 Lu are calculated in a Cranked Nilsson-Strutinsky approach keeping track of configurations and their evolution with spin. The outcome from calculations neglecting pairing and including pairing are compared. It is predicted that several yrast region configurations terminate at a very favored energy around I = 50 and that one of the observed bands is two transitions short of termination.
Magnetic properties of smooth terminating dipole bands in 110,112Te
2006
Three strongly coupled sequences have been established in Te-110,Te-112 up to high spins. They are interpreted in terms of deformed structures built on proton 1-particle-1-hole excitations that reach termination at I similar to 40h. This is the first observation of smooth terminating dipole structures in this mass region. Lifetime measurements have allowed the extraction of experimental B(M 1; 1 -> I - 1) and B(E2; I -> I - 2) reduced transition rates for one of the dipole bands in Te-110. The results support the deformed interpretation. (c) 2006 Elsevier B.V. All rights reserved.
