Particle realization of Bondi-Metzner-Sachs symmetry in 2+1 space-time
Carles Batlle, Víctor Campello, Joaquim Gomis
We construct a Lorentz invariant massive particle model in (2+1) space-time with an enlarged set of symmetries which includes Bondi-Metzner-Sachs (BMS) translations (supertranslati…
Polyharmonic Green Functions and Nonlocal BMS Transformations of a Free Scalar Field
Carles Batlle, Victor Campello, Joaquim Gomis
We express the nonlocal BMS charges of a free massless Klein-Gordon scalar field in 2+1 in terms of the Green functions of the polyharmonic operators. Using the properties of these…
A canonical realization of the Weyl BMS symmetry
Carles Batlle, Víctor Campello, Joaquim Gomis
We construct a free field realization of an extension of the BMS algebra in dimensional space-time. Besides the supertranslations and superrotations, the extension contains a…
Cardiac Segmentation on Late Gadolinium Enhancement MRI: A Benchmark Study from Multi-Sequence Cardiac MR Segmentation Challenge
Xiahai Zhuang, Jiahang Xu, Xinzhe Luo +20
Accurate computing, analysis and modeling of the ventricles and myocardium from medical images are important, especially in the diagnosis and treatment management for patients suff…
Combining Multi-Sequence and Synthetic Images for Improved Segmentation of Late Gadolinium Enhancement Cardiac MRI
Víctor M. Campello, Carlos Martín-Isla, Cristian Izquierdo +3
Accurate segmentation of the cardiac boundaries in late gadolinium enhancement magnetic resonance images (LGE-MRI) is a fundamental step for accurate quantification of scar tissue.…
Canonical Realization of (2+1)-dimensional Bondi-Metzner-Sachs symmetry
Carles Batlle, Victor Campello, Joaquim Gomis
We construct canonical realizations of the algebra as symmetry algebras of a free Klein-Gordon (KG) field in dimensions, for both the massive and massless…
