Renormalization of Supersymmetric QCD on the Lattice
Published in EPJ Web of Conferences
We perform a pilot study of the perturbative renormalization of a Supersymmetric gauge theory with matter fields on the lattice. As a specific example, we consider Supersymmetric N=1 QCD (SQCD). We study the self-energies of all particles which appear in this theory, as well as the renormalization of the coupling constant. To this end we compute, p...
Habitability of Mars: How Welcoming Are the Surface and Subsurface to Life on the Red Planet?
Published in Geosciences
Mars is a planet of great interest in the search for signatures of past or present life beyond Earth. The years of research, and more advanced instrumentation, have yielded a lot of evidence which may be considered by the scientific community as proof of past or present habitability of Mars. Recent discoveries including seasonal methane releases an...
A $C^m$ Lusin Approximation Theorem for Horizontal Curves in the Heisenberg Group
We prove a $C^m$ Lusin approximation theorem for horizontal curves in the Heisenberg group. This states that every absolutely continuous horizontal curve whose horizontal velocity is $m-1$ times $L^1$ differentiable almost everywhere coincides with a $C^m$ horizontal curve except on a set of small measure. Conversely, we show that the result no lon...
Eunomia: A Permissionless Parallel Chain Protocol Based on Logical Clock
The emerging parallel chain protocols represent a breakthrough to address the scalability of blockchain. By composing multiple parallel chain instances, the whole systems' throughput can approach the network capacity. How to coordinate different chains' blocks and to construct them into a global ordering is critical to the performance of parallel c...
Load Balancing for Ultra-Dense Networks: A Deep Reinforcement Learning Based Approach
In this paper, we propose a deep reinforcement learning (DRL) based mobility load balancing (MLB) algorithm along with a two-layer architecture to solve the large-scale load balancing problem for ultra-dense networks (UDNs). Our contribution is three-fold. First, this work proposes a two-layer architecture to solve the large-scale load balancing pr...
Emergence of metallo-b-lactamase producing gram-negative bacteria in a hospital with no history of Carbapenem usage in n...
Carbapenems are among the antibiotics of last resort against infections caused by antibiotic resistant bacteria. However, resistance to this important class of antibiotic is on the increase due to expression of metallo-betalactamases (MBLs). This study investigated the occurrence of MBL-producing bacteria in a healthcare facility in Sokoto, Nigeria...
Accrediting outputs of noisy intermediate-scale quantum computing devices
We present an accreditation protocol for the outputs of noisy intermediate-scale quantum devices. By testing entire circuits rather than individual gates, our accreditation protocol can provide an upper-bound on the variation distance between noisy and noiseless probability distribution of the outputs of the target circuit of interest. Our accredit...
Erratum
In the article ‘Learners’ views on the entrepreneurial activities engaged in during practical work in consumer studies’, which appeared on pp. 01 – 12 of Volume 47 (2019), the second author’s name should read Lulama ML Shange and not Lungile Shange. The online version of the article (https://www.ajol.info/index.php/jfecs/article/view/186901/176174)...
Characterization of the Unsteady Aerodynamics of Optimized Turbine Blade Tips through Modal Decomposition Analysis
Published in International Journal of Turbomachinery, Propulsion and Power
The present research focused on the analysis of the leakage flows developing from advanced blade tip geometries. The aerodynamic field of a contoured blade tip and of a high-performance rimmed blade were investigated against a baseline squealer rotor. Time-resolved numerical predictions were combined with high-frequency pressure measurements to cha...
