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...

CuS-graphene nanosheet (GNS) composites with well-defined morphology have been successfully fabricated via a simple one-pot hydrothermal route by using thioacetamide (TAA) as both the sulfur source and reducing agent. The as-prepared CuS-GNS composites with an appropriate content of graphene exhibited an even higher peroxidase-like catalytic activity than pristine CuS nanoparticles in acetate b...

A SnO/SnO2/GNS composite with controlled oxidation states and composition has been prepared through simple one-pot reduction of an EG suspension of SnCl2 and graphene oxide. The as-prepared composite was characterized by XRD, FT-IR, XPS, SEM, TEM and BET. SnO and SnO2 nanoparticles are uniformly distributed on the surface of the graphene. Taking advantage of the high electron conductivity of gr...

We consider the communication capacity of wireline networks for a two-unicast traffic pattern. The network has two sources and two destinations with each source communicating a message to its own destination, subject to the capacity constraints on the directed edges of the network. We propose a simple outer bound for the problem that we call the Generalized Network Sharing (GNS) bound. We show ...

In this paper a refractive index sensor based on localized surface plasmon resonance (LSPR) in a Plastic Optical Fiber (POF), is presented and experimentally tested. LSPR is achieved exploiting five-branched gold nanostars (GNS) obtained using Triton X-100 in a seed-growth synthesis. They have the uncommon feature of three localized surface plasmon resonances. The strongest LSPRs fall in two ra...

The RNA-dependent RNA polymerase (RdRp) of potato virus X (PVX) contains a glycine-lysine-serine (GKS) motif. This motif is present in the replication enzyme of many RNA viruses and is thought to be required for nucleoside triphosphate-binding. Three single amino acid changes, glycine to alanine (AKS), lysine to asparagine (GNS) and lysine to glutamate (GES) within the GKS motif of the PVX RdRp...
