Cartan Subalgebras For Non-Principal Twisted Groupoid C⁎-Algebras, Anna L. Duwenig, E Gillaspy, R Norton, S Reznikoff, S Wright

Faculty of Engineering and Information Sciences - Papers: Part B

2020 Elsevier Inc. Renault proved in 2008 [22, Theorem 5.2] that if G is a topologically principal groupoid, then C0(G(0)) is a Cartan subalgebra in Cr⁎(G,Σ) for any twist Σ over G. However, there are many groupoids which are not topologically principal, yet their (twisted) C⁎-algebras admit Cartan subalgebras. This paper gives a dynamical description of a class of such Cartan subalgebras, by identifying conditions on a 2-cocycle c on G and a subgroupoid S⊆G under which Cr⁎(S,c) is Cartan in Cr⁎(G,c). When G is a discrete group, we also describe the Weyl groupoid and twist associated to these Cartan …

An Unsupervised Deep Learning Technique For Susceptibility Artifact Correction In Reversed Phase-Encoding Epi Images, Soan Duong, Son Lam Phung, Abdesselam Bouzerdoum, Mark M. Schira

Faculty of Engineering and Information Sciences - Papers: Part B

© 2020 Elsevier Inc. Echo planar imaging (EPI) is a fast and non-invasive magnetic resonance imaging technique that supports data acquisition at high spatial and temporal resolutions. However, susceptibility artifacts, which cause the misalignment to the underlying structural image, are unavoidable distortions in EPI. Traditional susceptibility artifact correction (SAC) methods estimate the displacement field by optimizing an objective function that involves one or more pairs of reversed phase-encoding (PE) images. The estimated displacement field is then used to unwarp the distorted images and produce the corrected images. Since this conventional approach is time-consuming, we propose an end-to-end deep learning technique, …

Thermionic Emission In Nodal-Ring Semimetals, Suguo Chen, Sunchao Huang, Wenye Duan, Wei Shi, C Zhang

Faculty of Engineering and Information Sciences - Papers: Part A

© 2020 Author(s). We theoretically investigate the thermionic emission from nodal-ring semimetals. The thermionic emission is found to be anisotropic in the x- and y-directions. The anisotropic emission can be enhanced by increasing the radius of nodal-ring b. The main feature of nodal-ring semimetals not only results in anisotropic thermionic emission but also affects the value of thermionic emission current density (TECD). The TECD of the lower branch of the energy-momentum dispersion increases with b, while the TECD of the upper branch decreases with b. Unlike in conventional materials, the TECD in nodal-ring semimetals depends on Fermi energy that is …

© 2020 Author(s). We study the effect of quantum reflection over the barrier (ROB) in a thermionic cooling device. We find that the performance of refrigerators can be enhanced by the ROB effect if the bias voltage and the lattice thermal resistance of the semiconductor in the barrier region are both sufficiently high. Furthermore, the figure of merit Z T can be higher due to the ROB effect if the workfunction of the cathode is low and the lattice thermal resistance is high. The overall optimum Z T calculated with and without the ROB effect are 6.5 and 7.1, respectively. …
