Abstract:
AbstractAccurate spectral measurement and wavelength determination are fundamental and vital for many fields. A compact spectrum analyzer with high performance is expected to meet the growing requirements, and speckle-based spectrum analyzer is a potential solution. The basic principle is based on using the random medium to establish a speckle-to-wavelength mapping relationship for spectrum reconstruction. This article introduces current speckle-based spectrum analyzers with different schemes and reviews recent advances in this field. Besides, some applications by using speckle-based spectrum analyzers are also introduced. Finally, the existing challenges and the future prospects of using speckle for spectrum recovery are discussed.

Abstract:
Real-time spectrum analyzer is a hot instrument for signal analysis and spectrum monitoring. It has wide applications in wireless communication and high potential for smart reading. However, it is characterized with a high cost. Hence, a designed light version based on already available lab instruments is constructed for use in school lab. In this thesis, a simple oscilloscope and a computer were used in the process. Both instruments communicated through GPIB cable and MATLAB software was used for the processing tasks. In order to test the designed one, a simple signal generator was used. The signal was analyzed in both time domain and frequency domain. Then measurements of the signal over time were updated to a matrix of FFT and were plotted in 3D, showing spectrum variation over time. The application of this project to radio frequency analysis was also discussed.

Abstract:
FFT-based digital spectral analyzer has become more and more widely used as a result of the development of Digital Signal Processing (DSP) techniques. Modern Analog-to-Digital Converters (ADC) and processors have made it possible to make fast measurements with a limited number of hardware.   In this thesis, a design of a simple low-cost FFT-based digital spectrum analyzer was presented. The author discusses the design of each components of the system in qualitatively and quantitatively. The report presents the whole system design in detail which contains filter design, micro-controller design, UART transmission design and MATLAB GUI design. Some satisfying measurement result of the system were presented in the paper. The system can provide fast measurement with good accuracy. But the measured result has a limited range and resolution of the display is not very high. At last, the advantages and disadvantages of the system was discussed which is considered as guidelines for further work.

Thesis, The George Washington University, 2013. http://pqdtopen.proquest.com/#viewpdf?dispub=3560015.

Abstract:

Usage of cellular networks for data services is growing rapidly worldwide as more consumers browse the Internet, check emails, and watch videos on smartphones and tablets. To ensure that sufficient capacity is available on cellular and wireless networks, current utilization of the radio spectrum, an encumbered and finite resource, needs to be evaluated. Spectrum is usually made available by governmental regulatory bodies through auctions. From a policy and regulatory perspective, auctions of spectrum try to ensure the efficient use of spectrum by allocating it to the entities that value it the most. Auctions also generate revenues for governments. Cellular operators worldwide have been asking for allocation of more spectrum for cellular networks to support the growing demand of mobile data services. Perception of radio spectrum scarcity has been linked, sometimes linearly, to the higher demand of mobile data services and the greater market penetration of mobile broadband devices. To validate the "spectrum scarcity" notion, various elements of the wireless ecosystem, including network infrastructure, spectral efficiency of mobile technologies, and data offloading via unlicensed spectrum need to be appraised; and their effects on "spectrum utilization" need to be understood. Research presented here takes a system dynamics approach to study dynamic behavior among these elements and their effects on usage of spectrum through computer-based simulation. System dynamics provides a powerful means to model a complex system comprised of dependent and independent variables. With the help of the Causal Loop Diagram, we explain the research framework and formulate the hypotheses. A stock-and-flow model-based simulation is employed for hypotheses testing to justify the need for more spectrum. Dynamic behavior among different variables of the wireless ecosystem is also analyzed through this simulation. The study conducted here also explains why system dynamics appears to be a comprehensive approach to address the wireless industry's spectrum scarcity and utilization problem. Simulation results show that mobile data demand can exceed the current capacity of cellular networks causing a spectrum deficit if apt planning of spectrum policies and appropriate infrastructure investment are delayed.

Abstract:
L'association des méthodes optiques permet d'identifier les différentes espèces présentes dans les couches d'oxydes développées sur le cuivre depuis des épaisseurs de quelques nanomètres jusqu'à plusieurs micromètres. Les oxydes suivants: l'oxyde précurseur de Cu2O, de formule CuxO, Cu2O, Cu3O2 et CuO ont été caractérisés en spectroscopie UV-Vis-PIR en réflexion diffuse. Les défauts dans les oxydes cuivreux peuvent être identifiés par la spectroscopie de photoluminescence. Les premiers stades de l'oxydation du cuivre font intervenir un processus rapide suivant les réactions: 2Cu+1/2 O2Cu2O-3Cu2O+1/2 O2|2Cu3O2. Ainsi, à basse température (423° K) et pour les temps les plus longs, c'est l'oxyde Cu3O2 qui se forme. Dans le domaine de température 473-573° K, les résultats d'analyse démontrent clairement qu'il y a un changement périodique de la composition de la couche dans les premières étapes de l'oxydation. Les micrographies de ces couches, révèlent en extrême surface, un mélange de CuO et d'oxydes de cuivre (i). Pour les températures supérieures à 673° K, la couche a une structure multicouche CuO|Cu3O2|Cu2O|Cu

Abstract:
Hfq est une protéine bactérienne qui a un rôle pleiotropique. La principale fonction de la protéine Hfq bactérienne consiste à répondre aux stress que peut rencontrer la bactérie lors d’un changement environnemental, en utilisant essentiellement un contrôle post-transcriptionnel. La protéine, par sa capacité à interagir avec les ARN et notamment les petits ARN non codant, permet ainsi une régulation rapide de l’expression génétique. En outre la protéine interagit aussi avec l’ADN qu’elle aide à se structurer. Les mutations dans le gène qui code pour Hfq ont des effets pleïotropes (déterminant plusieurs caractères phénotypiques).D’un point de vue structural, la protéine adopte un repliement de type Sm, caractérisé par un oligomère toroïdal reposant sur la formation d’un feuillet β continu à 30 brins. Cependant, outre cette région Sm N-terminale, Hfq possède également une région C-terminale (CTR) de taille et de séquence variables selon les bactéries. Mon travail de thèse a porté sur l’analyse de cette région CTR chez la bactérie Escherichia coli. Cette région a en effet la capacité de former une structure de type amyloïde : structures auto-assemblées in vivo, à proximité de la membrane interne et dans le nucléoïde.Par l’utilisation de diverses techniques physico-chimiques (microscopie moléculaire, spectroscopie et microscopie infrarouge, dichroïsme circulaire et diffusion aux petits angles), mon travail a consisté à caractériser l’assemblage de cette région de Hfq ainsi que les facteurs l’influençant en particulier la présence d’acide nucléique. Une partie de mon travail de thèse a aussi consisté à mettre en place une méthode d’imagerie corrélative innovante permettant d’analyser la signature chimique et morphologique d’une fibre amyloïde unique. Mon travail a enfin porté sur l’analyse de l’effet de composés inhibant l’agrégation de la structure amyloïde, ce qui pourrait constituer une piste pour développer une nouvelle classe d’antibiotiques
Hfq is a pleiotropic bacterial protein that determines several phenotypic characteristics. Its main function is to facilitate responses to stresses that bacteria may encounter during environmental changes, mainly by using post-transcriptional genetic control. The protein, by its capacity to interact with RNA, in particular small non-coding RNA, enables a rapid regulation of gene expression. In addition, the protein also interacts with DNA and compacts it. From a structural point of view, the protein adopts an Sm-like fold, characterized by a toroidal oligomer formed by a continuous 30-stranded β-sheet. Besides its conserved N-terminal Sm domain, Hfq also possesses a C-terminal region (CTR) that can vary in size and sequence between bacteria. My PhD work focused on the analysis of this CTR region in Escherichia coli bacteria. Indeed, this region has the capacity to form an amyloid structure. This structural dynamic is related to the formation of self-assembled structures in vivo, in the proximity of the inner membrane and in the nucleoid.Using various physicochemical techniques (molecular microscopy, spectroscopy and infrared microscopy, circular dichroism and small angle X-ray scattering), my work consisted in characterizing the assembly of this region of Hfq, as well as the factors influencing its assembly (in particular, the presence of nucleic acids). A part of my work consisted in setting up an innovative correlative–imaging method to analyze the chemical and morphological signature of a single amyloid fibre. Finally, my work focused on the analysis of the effect of compounds that inhibit the aggregation of the amyloid structure, which could constitute a new way to develop a novel class of antibiotics

Abstract:
We review the structure of atoms to describe allowed intra-atomic electronic transitions following dipole selection rules. Inner shell ionization is followed by characteristic X-ray emission or non-radiative de-excitation processes leading to Auger electrons that involve three atomic levels. Photon incidence also results in characteristic photoelectron emission, reflecting the energy distribution of the electrons in the solid. We present details of laboratory and synchrotron sources of X-rays, and discuss their detection by wavelength or energy-dispersive spectrometers, as well as microanalysis with X-ray (XRF), or electron (EPMA) incidence. Characteristic X-ray intensities are quantified in terms of composition using corrections for atomic number (Z), absorption (A), and fluorescence (F). Electron detectors use electrostatic or magnetic dispersing fields; two common designs are electrostatic hemispheric or mirror analyzers. Auger electron spectroscopy (AES) and X-ray photoelectron spectroscopy (XPS), used for surface analysis, require ultra-high vacuum. AES is a weak signal, best resolved in a derivative spectrum, shows sensitivity to the chemical state and the atomic environment, provides a spatially-resolved signal for composition mapping, and can be quantified for chemical analysis using sensitivity factors. Finally, we introduce the basics of XPS, a photon-in, electron-out technique, discussed further in §3.

The COVID-19 pandemic changed the landscape of telehealth services. The goal of this paper was to identify demographic groups of patients who have used telemedicine services before and after the start of the pandemic, and to analyze how different demographic groups’ telehealth usage patterns change throughout the course of the pandemic. A de-identified study dataset was generated by querying electronic health records at the Mount Sinai Health System to identify all patients. 129,625 patients were analyzed. Demographic shifts in patients seeking telemedicine service were identified. There was significant increase in the middle age and older population using telehealth services. During the pandemic use of telemedicine services was increased among male patients and racial minority patients. Furthermore, telehealth services had expanded to a broader spectrum of medical specialties.

Abstract:
The aim of this pilot study was to identify social determinants of health (SDH) that affect disparities in cancer survival. A limited dataset was generated by querying electronic medical records (EHR) from an academic medical center in New York City between January 2003 and November 2020. Socio-demographic characteristics that affected survival in 22,096 cancer patients were analyzed using descriptive statistics and logistic regression analyses. Two subsets of adult patients were identified: patients who were deceased less than 1 year after diagnosis and patients who survived over 5 years after diagnosis. Percentage of individuals with short survival in Blacks and Whites was respectively 41.4% and 22.2% for lung cancer, 9.8% and 7.1% for colorectal cancer, 2.9% and 0.7% for breast cancer, 6.8% and 4.0% for multiple myeloma, and 1.4% and 0.8% for prostate cancer. Logistic regression identified SDH factors increasing likelihood of shorter survival that included older age, and being male, Black or Hispanic. We concluded that further analysis of a broader spectrum of SDH factors is warranted.

Electronic social networks have expanded communication possibilities. This chapter aims to present how such platforms allow the formation of virtual communities to support and exchange information and the inclusion of people with ASD (autism spectrum disorders) by comparing brand virtual communities from two countries, five from Brazil and one from the USA. Among interpretative methods, netnography and manual content analysis considering posts on each community were performed. Also, tweets about Autism Awareness Day were analyzed. As a result, it was possible to see that virtual communities' contribution allows dialogue among autists' relatives, releasing their suffering and sharing acceptable practices. Among contributions, this study helps to know the differences among various virtual communities and content in terms of viralization in health marketing.

Abstract:
Nanomaterials integration in biosensors designs are known to enhance sensing and signaling capabilities by exhibiting remarkably high surface area enhancement and intrinsic reactivity owing to their distinctive optical, chemical, electrical and catalytic properties. We present the synthesis and characterization of silver nanoparticles (AgNPs), and their immobilization on a silicon on-chip biosensor platform to enhance sensing capability for prostate specific antigen (PSA) - cancer biomarkers. Several techniques, including UV-Visible (UV-Vis) absorption spectrum, Fourier transforms infrared spectroscopy (FTIR), high resolution transmission electron microscopy (HRTEM), scanning electron microscopy (SEM) and field emission scanning electron microscopy (FESEM) were used for characterizing the AgNPs. The biochemical sensor consists of AgNPs immobilized on the receptor layer of a silicon avalanche mode light emitting device (Si AM LED) which enables on-chip optical detection biological analytes. A bio-interaction layer etched from the chip interacts with the evanescent field of a micro dimensioned waveguide. An array of detectors below the receptor cavity selectively monitor reflected light in the UV, visible, infrared and far infrared wavelength regions. AgNPs used as an immobilization layer in the receptor layer enhances selective absorption analytes, causing a change in detection signal as a function of propagation wavelength as light is dispersed. The analytes could range from gases to cancer biomarkers like prostate specific antigen.

In this Chapter we analyze a non-linear parametric interaction between Very Low Frequency (VLF) and Extremely Low Frequency (ELF) waves in the ionosphere. We demonstrate that nonlinear parametric coupling between quasi-electrostatic Lower Oblique Resonance (LOR) and ELF waves significantly contributes to the VLF electromagnetic whistler wave spectrum. Analytical and numerical results are compared with experimental data obtained during active space experiments and satellite data. These data clearly show that presence of VLF waves in the region of plasmasphere boundary layer, where there are no injected due to substorm/storm activity energetic electrons with energies of tens keV can strongly affect the radiation belt boundary.

Full text
Abstract:
The autonomous optoelectronic generator (OEO) is considered in the chapter as a source of low-noise oscillations. Differential equations are considered and methods with OEO modulation with direct and external modulation are analyzed. The complexity of both approaches is related to the non-standard way of description of the nonlinear method modulation for the internal (direct) structure and the utilization of the specific Mach-Zehnder modulator for the first stage on external modulation. The purpose of the presentation is to consider the main features of OEO as a low-noise generator. This includes consideration based on the study of differential equations, the study of transients in OEO, and the calculation of phase noise. It is shown that different types of fibers with low losses at small bending radii can be used as a FOLD in OEO. The important role of the choice of a coherent laser for OEO with a small spectral line width is shown. The prospects of using structured fibers with low losses at bends of less than 10 mm in OEO are described. The results of modeling dynamic processes in OEO with direct modulation are presented.

Abstract:
Oxide micro- and nanoparticles are ubiquitous in the natural environment. They have long been used as catalysts, but have found novel applications with the advent of nanotechnologies. From a fundamental point of view, they bridge the gap between the properties of isolated atoms or molecules and those of bulk condensed phases. They present a large spectrum of atomic and electronic structures, due to their finite size in the three dimensions of space and the fact that their atoms are nearly all surface atoms. They represent the first stages of nucleation and growth of larger size oxides, and their stability and properties which depend upon the thermodynamic conditions under which they are formed, largely impact the final product. This chapter reviews their specific properties and analyses their physical origin, both when they are produced in the gas phase, in an aqueous environment, or when cation mixing takes place.

Abstract:
Each radioactive material has its unique energy signature (spectrum). Spectrum shift during measurements is a well know phenomenon which occurs due to environmental temperature changes which affect the electronics, and can lead to misidentification of the radioactive material. We developed a new portable spectroscopy workstation based on Digital Signal Processing (DSP) technology, which includes an analog circuit, a Multi Channel Analyzer (MCA), 7 power suppliers and a laptop. The designed system, to which wide range of radioactive detectors can be attached, uses to identify a sampled radioactive material according to its spectrum. In order to prevent the spectrum shift phenomena, both natural and forced convection heat transfer experiments were carried out. Few configurations were tested during these experiments whose results yielded the final electronic packaging configuration of the system as well as the definition of the stabilization time of the system.

Abstract:
The effect of explicit molecules of solvent in the electronic spectrum of anhydride maleic groups was studied by quantum-chemical methods in ethanol and chloroform. An implicit method of solvation was also applied and showed no distinction between the two solvents. The addition of eight explicit molecules of the solvent resulted in an improvement of the calculated UV-Vis spectra. It was also possible to analyze the influence of different solvents in the molecular orbital associated with electronic transitions.
