We address the latency challenges in a high-density and high-load scenario for an ultra-reliable low-latency communication (URLLC) network which may coexist with enhanced mobile broadband (eMBB) services evolving wireless networks. propose new radio resource management (RRM) scheme consisting of combination time domain (TD) frequency (FD) schedulers specific URLLC eMBB users. also develop user ...

Considering coupled phase model oscillator systems with non-identical time delays, we study the possibility of close-to-zero phaselag synchronization (ZPS) without frequency depression (FD). FD refers to nearly vanishing frequencies of the synchronized oscillators (in comparison to the intrinsic frequencies); its absence is crucial for interpretations related to brain dynamics. Discussing an ex...

The protein Etp1 of Schizosaccharomyces pombe consists of an amino-terminal COX15-like domain and a carboxy-terminal ferredoxin-like domain, Etp1(fd), which is cleaved off after mitochondrial import. The physiological function of Etp1(fd) is supposed to lie in the participation in the assembly of iron-sulfur clusters and the synthesis of heme A. In addition, the protein was shown to be the firs...

Mutual interference is a key obstacle in the realistic adoption of full-duplex (FD) technique in future wireless cellular networks. Interference is a much more pressing problem for FD system than for the conventional half-duplex (HD) system, because FD allows the same time-frequency resource to be used for both uplink and downlink, thus possibly creating myriad interference between multiple tra...

We present a new free library for Constraint Logic Programming over Finite Domains, included with the Ciao Prolog system. The library is entirely written in Prolog, leveraging on Ciao's module system and code transformation capabilities in order to achieve a highly modular design without compromising performance. We describe the interface, implementation, and design rationale of each modular co...

Nephropathy is one of the major complications of Fabry Disease (FD) and mainly includes reduced glomerular filtration rate (GFR) and proteinuria. Despite the frequency, scarce information exists regarding the frequency of CKD as well as other related complications in FD patients in Argentina. The aim of the study was to measure the prevalence of CKD at diagnosis of FD as well as to describe oth...

In this paper, we propose a transmit multi-block frequency-domain equalization (MB-FDE) for frequency-domain spacetime block coded joint transmit/receive diversity (FD-STBC-JTRD). Noting that a STBC codeword consists of multiple coded blocks, the transmit MB-FDE uses the multiple transmit FDE weight matrices, each associated with each coded block. Both single-carrier (SC) transmission and ortho...

In this paper, a novel frequency-domain model (FD-model) for the frequency selective, Ricean fading radio channel is presented. Frequency domain filtering and the Hilbert transform are used to generate samples of the channel's transfer function with appropriate frequency correlation properties (WSSUS model). One of the main advantages of this approach is the availability of analytical expressio...

PURPOSE The frequency-doubling technology (FDT) perimeter has no provision for introducing corrective lenses, save for the patient's spectacles, and so patients are sometimes tested in the presence of moderate levels of defocus. The effect of defocus on frequency-doubling (FD) sensitivity was determined for both the commercially available instrument and for smaller targets that may be useful in...

AIMS The purpose of this single centre registry is to assess safety and feasibility of the frequency domain optical coherence tomography (FD-OCT) system during coronary interventions. METHODS AND RESULTS Ninety patients with unstable or stable coronary artery disease were included in this study. OCT imaging was performed in a first group of 40 patients (group 1), to evaluate ambiguous/interme...
