How to construct a measurement matrix with good performance and easy hardware implementation is the core research problem in compressed sensing. In this paper, we present a simple and efficient measurement matrix named Incoherence Rotated Chaotic (IRC) matrix. We take advantage of the well pseudorandom of chaotic sequence, introduce the concept of the incoherence factor and rotation, and adopt ...
Internet-of-Everything (IoE) has gradually been recognized as an integral part of future wireless networks. In IoE, there can be ultra-massive number smart devices various types to served, imposing multi-dimensional requirements on communication, sensing, and security. this article, we provide a tutorial overview the promising intelligent reflection communication (IRC) technologies, including r...
We report the results of the presently lowest frequency spectral line survey of the asymptotic giant branch carbon star IRC+10 216. The entire Arecibo C band (4–6 GHz) was observed with a noise level of 0.3 mJy (1 ). We report the detection of HC5N (J 1⁄4 2 1), which is the lowest frequency transition of the HC5N molecule found in the envelope of IRC +10 216. The HC5N J 1⁄4 2 column density der...
New speckle holographic images of the T Tauri infrared companion (T Tauri IRC; T Tauri S) reveal it to be a double system with a sky-projected separation of 0&farcs;05, corresponding to a linear distance of 7 AU. The presence of this third star may account for the relative paucity of dust surrounding the IRC.
For given positive integers u and v with u ≡ v ≡ 0 (mod 6), let IRC(u; v) denote an incomplete resolvable minimum covering of pairs by triples of order u having a hole of size v. It is proved in this paper that there exists such an IRC(u; v) if and only if u¿ 3v. c © 2003 Elsevier B.V. All rights reserved.
The development of dyskinesias following chronic L-DOPA replacement therapy remains a major problem in the long-term treatment of Parkinson's disease. This study aimed at evaluating the effect of IRC-082451 (base of BN82451), a novel multitargeting hybrid molecule, on L-DOPA-induced dyskinesias (LIDs) and hypolocomotor activity in a non-human primate model of PD. IRC-082451 displays multiple pr...
Human melanocortin 4 receptor (hMC4R) mutations with in vitro functional effects are responsible for 0.5-2.5% of severe obesity. Designing ligands that are able to counteract this in vitro-associated molecular defect is crucial to develop specific anti-obesity drugs in these genetically associated cases. We analyzed the in vitro effect of two novel melanocortin agonists, IRC-022493 and IRC-0225...
Tubulin is a validated target for antitumor drugs. However, the effectiveness of these microtubule-interacting agents is limited by the fact that they are substrates for drug efflux pumps (P-glycoprotein) and/or by the acquisition of point mutations in tubulin residues important for drug-tubulin binding. To bypass these resistance systems, we have identified and characterized a novel synthetic ...
The present study deals with the empirical analysis of patterns in the evolution of interest rate curves (IRC). The main topic is to consider IRC as objects (curves) embedded into high-dimensional space and to study similarities and differences between them. This is a typical problem of clustering and classification in machine learning. In fact, theses data – IRC, can be considered as functiona...
