In this paper, our aim is to derive a phase spectrum representation computed via the short-time Fourier transform. Specifically, we are interested in developing a narrow-band speech representation – employing 20-40 ms analysis windows. Furthermore, this representation should be as physically meaningful as the magnitude spectrum. To achieve these ends, we concentrate on instantaneous frequency (...

The telecommunication world is experiencing the 5th generation (5G) networks deployment including use of millimeter wave (mmW) frequency bands to satisfy capacity demands. This leads extensive optical communications, especially fiber connectivity at last mile access and edge networks. In this paper we outline free space optics (FSO) technologies for as part 5G fronthaul network. We investigate ...

Research has examined the benefits and costs of employing adults with autism spectrum disorder (ASD) from the perspective of the employee, taxpayer and society, but few studies have considered the employer perspective. This study examines the benefits and costs of employing adults with ASD, from the perspective of employers. Fifty-nine employers employing adults with ASD in open employment were...

The Spo11-generated double-strand breaks (DSBs) that initiate meiotic recombination are dangerous lesions that can disrupt genome integrity, so meiotic cells regulate their number, timing, and distribution. Mechanisms of this regulation remain poorly understood. Here, we use Spo11-oligonucleotide complexes, a byproduct of DSB formation, to reveal aspects of the contribution of the Saccharomyces...

Loss of heterozygosity (LOH) is a common genetic alteration in tumors and often extends several megabases to encompass multiple genetic loci or even whole chromosome arms. Based on marker and karyotype analysis of tumor samples, a significant fraction of LOH events appears to arise from mitotic recombination between homologous chromosomes, reminiscent of recombination during meiosis. As DNA dou...

DNA repair activity of malignant cells seems to influence therapeutic outcome and patients' survival. Herein, we investigated the mechanistic basis for the link between DNA repair efficiency and response to antimyeloma therapy. Nucleotide excision repair (NER), interstrand cross-links repair (ICL/R), double-strand breaks repair (DSB/R), and chromatin structure were evaluated in multiple myeloma...

Two novel betaine surfactants with distinct hydrophilic headgroups were synthesized, including carboxybetaine surfactant (DCB) and sulfobetaine (DSB). Their properties of reducing the interfacial tension (IFT) Xinjiang crude oil/water studied under alkaline-free conditions, as their thermal stability, wettability, emulsification properties. The chemical structures target products characterized ...

In this research, we present an analysis of a photonic integrated frequency shifter as stage for THz dual comb generator. We studied the performance PIC by simulating it with standard building blocks, and aimed toward improvement output signal quality. revised two approaches modes generating double side band modulation suppressed carrier (DSB-SC) Mach Zehnder modulator structure (MZM). One appr...

OBJECTIVE The passage of ionizing radiation in living cells creates clusters of damaged nucleotides in DNA. In this study, DNA strand breaks induced by the beta particle of iodine-131 (I-131), have been determined experimentally and compared to Monte Carlo simulation results as a theoretical method of determining(131)I damage. MATERIALS AND METHODS In this experimental study, in order to crea...
