Armchair graphene nanoribbons are considered unsuitable for spin caloritronic applications, due to the lack of intrinsic magnetism. Inspired by progress on fabricating carbon nanotubes with Janus edges Bets et al. (2019) [26], we construct edges, where one edge is armchair type and other possesses triangular protrusions zigzag-armchair or zigzag-zigzag sub-edges. By first-principles calculation...

Abstract Critical comments on Guido Melchior’s book, Knowing and Checking: An Epistemological Investigation (2019). In the second part of his Melchior aims to employ sensitivity account epistemic concept checking explain well-known puzzle cases about knowing . My focus explanation knowledge-closure puzzles, as exemplified by Dretske’s zebra case. I raise three critical points proposes for puzzl...

This paper studies an unmanned aerial vehicle (UAV)-enabled wireless sensor network, in which one UAV flies the sky to collect data transmitted from a set of ground nodes (GNs) via distributed beamforming. We consider two scenarios with delay-tolerant and delay-sensitive applications, GNs send common/shared messages adaptive- fixed-rate transmissions, respectively. For scenarios, we aim maximiz...

The emission of gravitational waves (GWs) during single-single close encounters in galactic nuclei (GNs) leads to the formation and rapid merger highly eccentric stellar-mass black hole (BH) binaries. distinct distribution physical parameters makes it possible statistically distinguish this source population from others. Previous studies determined expected binary parameter for single GNs. Here...

The extreme extinction ($A_V\sim30$\,mag) and its variation on arc-second scales towards the Galactic centre hamper study of stars. Their analysis is restricted to near infrared (NIR) regime, where curve can be approximated by a broken power law. Therefore, correcting for fundamental analyse structure stellar population central regions our Galaxy. We aim to, (1) discuss different strategies de-...

In this work, we optimize the 3D trajectory of an unmanned aerial vehicle (UAV)-based portable access point (PAP) that provides wireless services to a set ground nodes (GNs). Moreover, as per Peukert effect, consider pragmatic non-linear battery discharge for UAV’s battery. Thus, formulate problem in novel manner represents maximization fairness-based energy efficiency metric and is name...

Credit Card Fraud is one of the biggest threats to business establishments today. This paper presents a cascade artificial neural network for the recognition of credit card fraud detection. This system aims at attaining a very high recognition rate and a very high reliability, In other words, excellent recognition performance of credit card fraud detection was obtained. Then, One solution was p...
