Design techniques for high-speed low-power wireline receivers
Creators: name: Zargaran Yazd, Arash
Publisher: name: University of British Columbia
Year: 2013

description: High-speed data transmission through wireline links, either copper or optical based, has become the backbone for modern communication infrastructure. Since at multi-Gb/s data rates the transmitted signal is attenuated and distorted by the channel, sophisticated analog front-end and/or digital signal processing are required at the receiver (RX) to recover data and clock from the received signal. In this thesis, both analog- and digital-based receivers are investigated, and power-reduction techniques are exploited at both system- and circuit levels. A speculative successive-approximation register (speculative/SAR) digitization algorithm is proposed for use at the receiver front-end of digital receivers that combines equalization and data recovery with the digitization step at the front-end analog-to-digital converter (ADC). Furthermore, architecture for quadrature clock generation is proposed which is of use in both analog and digital receivers. Then, an analog clock and data recovery (CDR) architecture suitable for high data rates (e.g., beyond 10 Gb/s) is proposed that utilizes a wideband data phase generation technique to facilitate mixer-based phase detection. The CDR architecture is implemented and experimentally validated for a 12.5 Gb/s system. Finally, a mixed-mode hardware-efficient CDR architecture is proposed that exploits both analog and digital design techniques to reach a robust operation suited for long-haul optical link communications. Proof-of-concept prototypes of the proposed RX architectures are designed and implemented in 65 nm and 90 nm CMOS processes. The prototypes are successfully tested. Note that although individual performance merits of the each prototype may not necessarily outperform that of the state-of-the-art, however, the prototypes confirm the feasibility of the proposed structure. Furthermore, the proposed architectures can be used at higher data rates particularly if more advanced technologies with higher device transit frequency, (fT), is used.

description: Die Zuwanderung nach Deutschland ist seit 2011 stark gestiegen, hauptsächlich durch Zuzüge von Bürgerinnen und Bürgern aus den in den Jahren 2004 und 2007 der EU beigetretenen Ländern und anderen Ländern des Euroraums. Der Abbau von Zuwanderungshindernissen und die konjunkturell bedingt gute Lage auf dem Arbeitsmarkt im Vergleich zu anderen europäischen Ländern sind die wesentlichen Gründe dafür. Modellsimulationen zeigen, dass die BIP-Wachstumsrate Deutschlands zwischen 2011 und 2016 ohne die EU-Zuwanderung um jahresdurchschnittlich rund 0,2 Prozentpunkte niedriger gewesen wäre. Es liegen aber weiterhin strukturelle Zuwanderungshindernisse vor. Auch könnte in Zukunft wegen der konjunkturellen Erholung und des demografischen Wandels in anderen EU-Ländern die Zuwanderung aus der EU nicht mehr so stark ausfallen wie bisher. Deshalb ist es wichtig, die Migrationsanreize zu stärken, unter anderem, indem Zuwanderer mehr Möglichkeiten bekommen, eine ihrer Qualifikation entsprechende Beschäftigung zu finden. Neben der EU-Zuwanderung kann es für die deutsche Wirtschaft zudem von Vorteil sein, den Arbeitsmarktzugang für Fachkräfte aus Drittstaaten zu erleichtern.

description: The Best Choice: Sleeping Between 19 to 3 (or 4). Based on Data of 6000 Iranian Families. Most melatonin secretion occurs between 2 and 4 am in people who are asleep (during rapid irregular eye movements during sleep). Therefore, waking up during these hours reduces melatonin secretion. Decreased melatonin secretion increases insulin secretion during these hours. Therefore, waking up at 2 to 4 o'clock can help treat metabolic syndrome or similar conditions. Perhaps the reason for the minimal risk of SARS-Cov-2 apparent Infection in people who wake up at 4 am lies in the relationship between melatonin and insulin on the one hand, and the relationship between insulin and SARS-Cov-2 risks on the other. Another possibility can be raised: During deep sleep, especially around 3 to 4 a.m., as well as during the REM phase of sleep, cytokines and free ATPs are released. This event may exacerbate the cytokine storm and worsen the SARS-COV-2 condition and symptoms. There is statistical evidence from Google Trends that the deteriorating condition of COVID-19 patients, in different countries involved in the pandemic, is experiencing a worsening of the condition every day between 3 and 7 a.m. this evidence suggests that deep sleep, especially between 3 and 7 a.m., can exacerbate SARS-COV-2 disease. Therefore, it should be considered that through the management of patients' sleep hours, it may be possible to better control treatment outcomes to reduce mortality. Also, more research should be done to investigate the effect of patients' sleep time and sleep patterns on the SARS-COV-2 biological processes.

description: So far, no supersymmetric particles have been detected at the Large Hadron Collider (LHC). However, the recent Higgs results have interesting implications for the SUSY parameter space. In this paper, we study the consequences of an LHC Higgs signal for a model with non-universal gaugino masses in the context of SU(5) unification. The gaugino mass ratios associated with the higher representations produce viable spectra that are largely inaccessible to the current LHC and direct dark matter detection experiments. Thus, in light of the Higgs results, the non-observation of SUSY is no surprise.

description: We study conformally-flat initial data for an arbitrary number of spinning black holes with exact analytic solutions to the momentum constraints constructed from a linear combination of the classical Bowen-York and conformal Kerr extrinsic curvatures. The solution leading to the largest intrinsic spin, relative to the ADM mass of the spacetime epsilon_S=S/M^2_{ADM}, is a superposition with relative weights of Lambda=0.783 for conformal Kerr and (1-Lambda)=0.217 for Bowen-York. In addition, we measure the spin relative to the initial horizon mass M_{H_0}, and find that the quantity chi=S/M_{H_0}^2 reaches a maximum of χ^{max}=0.9856 for Lambda=0.753. After equilibration, the final black-hole spin should lie in the interval 0.9324

description: Die Inflationsrate im Euroraum lag in den vergangenen fünf Jahren deutlich unterhalb der von der Europäischen Zentralbank (EZB) angestrebten Inflationsrate von knapp unter zwei Prozent zur mittelfristigen Preisstabilisierung. Verantwortlich hierfür waren, wie die vorliegende Analyse zeigt, niedrige Inflationserwartungen, hohe Arbeitslosenquoten und externe Faktoren wie niedrige Rohölpreise. Mitte dieses Jahres zog die Teuerung im Euroraum wieder deutlich an. Im Juni beschloss der EZB-Rat das Ende der Staatsanleihenkäufe bis Dezember dieses Jahres und stellte ein erstmaliges Anheben der Leitzinsen voraussichtlich nach dem Sommer 2019 in Aussicht. Dafür müsste sich aber die Inflationsdynamik nachhaltig fortsetzen. Allerdings hat sich die Kerninflation, ohne Energieund Nahrungsmittelpreise, bislang recht verhalten entwickelt. Die EZB setzt besonders auf die anziehende Lohndynamik als Treiber der Kerninflation in den kommenden Jahren. Wie die DIW-Berechnungen zeigen, bestand dieser Zusammenhang zwar bisher, war allerdings recht schwach ausgeprägt. Damit die Kerninflation in den kommenden Jahren die mittelfristige Preisstabilität stützt, müssten die Löhne weiterhin deutlich steigen.

In diesem Bericht wird die finanzielle Inklusion einer Gruppe von 31 in Berlin lebenden syrischen Geflüchteten anhand von Befragungen untersucht. Offensichtlich funktioniert der Zugang zu einfachen Bankkonten gut, viele Befragte nutzen ihr Bankkonto aber nur wenig. Außerdem zeigt sich, dass die Befragten darüber hinaus keine Bankprodukte nutzen, sondern bei finanziellen Engpässen auf ihr soziales Netzwerk zurückgreifen. Wenig Erfahrung im Umgang mit Finanzprodukten und eine geringe finanzielle Bildung der Befragten könnten Gründe hierfür sein. Um ein repräsentatives Bild der finanziellen Inklusion Geflüchteter zu zeichnen, ist eine größer angelegte Informationserhebung notwendig.

description: We study here circular timelike geodesics in the Janis-Newman-Winicour and Gamma metric spacetimes which contain a strong curvature naked singularity and reduce to the Schwarzschild metric for a specific value of one of the parameters. We show that for both the metrics the range of allowed parameters can be divided into three regimes where structure of the circular geodesics is qualitatively different. It follows that the properties of the accretion disks around such naked singularities can be significantly different from those of disks around black holes. This adds to previous studies showing that if naked singularities exist in nature, their observational signature would be significantly different from that of the black hole.

description: In this thesis, we will discuss the parameter estimation of post-merger waveforms of binary neutron star collisions. To achieve this, we shall first introduce the notion of estimation theory and bayesian statistics. Furthermore, we will introduce gravitational waves and how they emerge from linear perturbations. After setting up the necessary language to formulate and solve our problem, we are in position to use statistical methods to estimate the parameters of a proposed analytic model for the post-merger waveform of binary neutron star merger, using numerical waveforms from the CoRe database and by the work of Soultanis et. al. We motivate a certain methodology which carefully uses knowledge of empirical relations and classifications in order to provide a robust parameter estimation. Finally, we make use of the Preconditioned Monte Carlo method in order to make the wall time of each estimation run significantly lower even without parallelizing.

description: Im Zentrum der Diskussion über eine Integration von Geflüchteten steht vielfach die erfolgreiche Eingliederung in den Arbeitsmarkt. Eine Untersuchung auf Basis einer repräsentativen Befragung von Geflüchteten zeigt, dass der Einstieg in den Arbeitsmarkt von Geflüchteten, die seit 2010 nach Deutschland kamen, etwa in der gleichen Geschwindigkeit verlief wie im Fall früherer Fluchtzuwanderung: Im dritten Jahr nach Zuwanderung haben etwa die Hälfte der männlichen Geflüchteten erste Arbeitsmarkterfahrungen in Deutschland gesammelt, bei weiblichen Geflüchteten ist es nur etwa ein Viertel. Oftmals liegt die erste Tätigkeit in Deutschland unter dem Tätigkeitsniveau der Beschäftigung im Herkunftsland. Trotz des schwierigen Arbeitsmarkteinstiegs findet sich unter Geflüchteten eine hohe Motivation, eine Beschäftigung aufzunehmen oder in Bildung zu investieren. Unterschiede innerhalb der Gruppe der Geflüchteten zeigen sich zwischen Geschlechtern, nach dem Grad der selbst eingeschätzten Gesundheit und nach der Erwerbsbiografie im Herkunftsland. Eine besonders hohe Motivation zu Erwerbstätigkeit und Weiterbildung zeigen Personen, die im Herkunftsland bereits erwerbstätig waren. Da ein Großteil der Geflüchteten auch ohne Berufsabschluss über Berufserfahrung in Fachkrafttätigkeiten verfügt und etwa die Hälfte bereit wäre, eine Aus- und Weiterbildung zu absolvieren, sollten schnellere und flexiblere Wege zum formalen Vollabschluss unter Berücksichtigung der Berufserfahrung eingeführt werden.

Prosodic structure patterns in multisyllabic word productions of Granada Spanish-speaking children with typical versus protracted phonological development
Creators: name: Schretlen, Christine Elaine
Publisher: name: University of British Columbia
Year: 2013

description: The primary aim of this study was to determine whether monolingual Granada Spanish-speaking children with protracted phonological development (PPD) perform differently from their typically-developing (TD) peers on measures of word stress, word length and word shape in multisyllabic words (MSWs). Previous research has shown that MSW productions can indicate PPD in English-speaking children (James, 2006). However there is no evidence to date of direct comparisons between monolingual Spanish-speaking children with typical and protracted phonological development on MSW productions. Fifty-nine monolingual Spanish-speaking children ages 3;0 to 5;11 were recruited for an original cross-linguistic study in Granada, Spain: 30 with TD and 29 with PPD. All MSW productions in the original data were extracted to create an analysis set for the current study. A total of 36 multisyllabic and 6 disyllabic single word elicitations were analyzed for each participant. A multisyllabic rubric based on principles of non-linear phonology was used to score MSW productions on word stress, word length and word shape. The rubric produced three types of mismatch scores for each child, including a word structure mismatch score, a segment-structure interaction mismatch score and a combined word structure and segment-structure interaction mismatch score. Descriptive and inferential analyses were performed on all three types of mismatch scores. Overall, children in the PPD group showed significantly more mismatches than their aged-matched TD peers. Word structure mismatch scores decreased as age increased, while mismatch scores increased with increased word length. No effect of gender was found. Common mismatch patterns in both the PPD and TD groups were syllable deletion, single vowel deletion and assimilation. Consonant deletion was also frequent, both for singleton consonants and for consonants in word-initial and word-medial sequences. Mismatch patterns were more common in initial unstressed syllables than in non-initial stressed syllables. The results of this study underscore the importance of using MSWs in analysis of children’s phonological productions, because group and age effects were found in 3- and 4-syllable targets that were obscured in 2-syllable targets. Further research is necessary to allow generalization of the results to other populations and to find potential clinical applications of the scoring rubric.
title: Bactericidal Effects of Low Temperature Atmospheric Pressure Plasma on Porphyromonas Gingivalis
Creators: name: Mahasneh, Arwa
Publisher: name: Old Dominion University Libraries
Year: 2009

description: Purpose: The biomedical application of low temperature atmospheric pressure plasma (LTAPP) is a collaborative interest for engineering, medical, dental and biological researchers. This laboratory study tested whether LTAPP can limit growth of Porphyromonas gingivalis, a periodontal pathogen strongly associated with periodontal disease, disease progression, and refractory periodontitis. Methods: After extensive pilot trials, the study consisted of 24 agar plate samples of P. gingivalis- 20 samples were exposed to LTAPP at 5, 7, 9 and 10 minutes and 4 control samples were exposed to helium gas only. Immediately after exposures, the samples were incubated anaerobically for 72 hour at 3 7°C. After 72 hours, zones of inhibition were measured. Results: After 5, 7, 9, and 11 minutes of exposure times, results reveal a statistically significant difference in the bactericidal effect of the LTAPP on P. gingivalis compared to control bacteria not exposed, as measured by zone of inhibition (cm) (p<0.0001). Differences in the bactericidal effects were significant for each pair of consecutive time points: 5 minutes verses 7 minutes, 7 minutes verses 9 minutes, and 9 minutes verses 11 minutes (p= 0.0360, p= 0.0009, and p<0.0001, respectively). Conclusions: LTAPP has a significant dose related bactericidal effect on P. gingivalis, as measured by zone of inhibition.
An Analytic Formula for the Supercluster Mass Function

Subjects: subject: Cosmology and Nongalactic Astrophysics (astro-ph.CO)

description: We present an analytic formula for the supercluster mass function which is constructed by modifying the extended Zel'dovich model for the halo mass function. The formula has two characteristic parameters whose best-fit values are determined by fitting to the numerical results from N-body simulations for the standard LambdaCDM cosmology. The parameters are found to be independent of redshifts and robust against variation of the key cosmological parameters. Under the assumption that the same formula for the supercluster mass function is valid for non-standard cosmological models, we show that the relative abundance of the rich superclusters should be a powerful indicator of any deviation of the real universe from the prediction of the standard LambdaCDM model.

description: Familie hat für das persönliche Wohlbefinden eine große Bedeutung – das gilt vor allem für Geflüchtete, deren Familienmitglieder oftmals im Herkunftsland zurückbleiben. Dieser Bericht nimmt die Familienstruktur von Geflüchteten, die zwischen Januar 2013 und Januar 2016 nach Deutschland kamen, und deren Wohlbefinden erstmals detailliert unter die Lupe. Er basiert auf Daten der IAB-BAMF-SOEP-Stichprobe von nach Deutschland Geflüchteten. Insgesamt haben neun Prozent der 18- bis 49-Jährigen minderjährige Kinder, die im Ausland leben. Zwölf Prozent dieser Geflüchteten haben einen Ehepartner oder eine Ehepartnerin im Ausland. Befindet sich die Kernfamilie in Deutschland – was bei Frauen deutlich häufiger der Fall ist als bei Männern –, sind die Geflüchteten messbar zufriedener mit ihrem Leben. Diese Befunde bestätigen sich auch dann, wenn weitere potentielle Faktoren für das Wohlbefinden berücksichtigt werden. Für eine gelungene Migrations-, Integrations- und Familienpolitik sollten diese Erkenntnisse stärker beachtet werden – nicht zuletzt in der Debatte um den Familiennachzug.

description: One-photon and multi-photon absorption, spontaneous and stimulated photon emission, resonance Raman scattering and electron transfer are important molecular processes that commonly involve combined vibrational-electronic (vibronic) transitions. The corresponding vibronic transition profiles in the energy domain are usually determined by Franck-Condon factors (FCFs), the squared norm of overlap integrals between vibrational wavefunctions of different electronic states. FC profiles are typically highly congested for large molecular systems and the spectra usually become not well-resolvable at elevated temperatures. The (theoretical) analyses of such spectra are even more difficult when vibrational mode mixing (Duschinsky) effects are significant, because contributions from different modes are in general not separable, even within the harmonic approximation. A few decades ago Doktorov, Malkin and Man'ko [1979 J. Mol. Spectrosc. 77, 178] developed a coherent state-based generating function approach and exploited the dynamical symmetry of vibrational Hamiltonians for the Duschinsky relation to describe FC transitions at zero Kelvin. Recently, the present authors extended the method to incorporate thermal, single vibronic level, non-Condon and multi-photon effects in energy, time and probability density domains for the efficient calculation and interpretation of vibronic spectra. Herein, recent developments and corresponding generating functions are presented for single vibronic levels related to fluorescence, resonance Raman scattering and anharmonic transition.

description: We derive an analytical form of the Schmidt modes of spontaneous parametric down-conversion (SPDC) biphotons in both Cartesian and polar coordinates. We show that these correspond to Hermite-Gauss (HG) or Laguerre-Gauss (LG) modes only for a specific value of their width, and we show how such value depends on the experimental parameters. The Schmidt modes that we explicitly derive allow one to set up an optimised projection basis that maximises the mutual information gained from a joint measurement. The possibility of doing so with LG modes makes it possible to take advantage of the properties of orbital angular momentum eigenmodes. We derive a general entropic entanglement measure using the Rényi entropy as a function of the Schmidt number, K, and then retrieve the von Neumann entropy, S. Using the relation between S and K we show that, for highly entangled states, a non-ideal measurement basis does not degrade the number of shared bits by a large extent. More specifically, given a non-ideal measurement which corresponds to the loss of a fraction of the total number of modes, we can quantify the experimental parameters needed to generate an entangled SPDC state with a sufficiently high dimensionality to retain any given fraction of shared bits.

La collezione di disegni con misure di Isidro González Velázquez nella Real Academia de San Fernando di Madrid
Creators: name: García Sánchez, Jorge

Year: 2021

description:

Isidro González Velázquez’s experiences and works in Italy, sponsored by the monarch Charles IV with the purpose of studying the antiquities of Rome, are better known than those of the rest of the Spanish pensionados of the eighteenth century, thanks to the conservation of plans, drawings and documents of the architect in different institutions. Recently, the Real Academia de San Fernando acquired an important collection of drawings with measures by Velázquez, mostly related to classical monuments. This collection comes to enlighten the fieldwork system of Velázquez, and in general of the students of architecture of his time, the state of conservation of the constructions he was interested in (the temples of the Forum, the Theatre of Marcellus, the Forum of Augustus, etc.) and the professional relationships that he established in order to carry out the measurement of these classical buildings.

description: In this work we present the results for the investigation of intermediate-mass fragment (IMF) production with the proton-induced reaction at 660 MeV on 238U and 237Np target. The data were obtained with the LNR Phasotron U-400M Cyclotron at Joint Institute for Nuclear Research (JINR), Dubna, Russia. A total of 93 isotopes, in the mass range of 30 < A < 200, were unambiguously identified with high precision. The fragment production cross sections were obtained by means of the induced-activation method in an off-line analysis. Mass-yield distributions were derived from the data and compared with the results of the simulation code CRISP for multimodal fission. A discussion of the super-asymmetric fragment production mechanism is also given.

Body Weight and Mortality Risk in Community-Dwelling Older Adults

Subjects: classificationCode: 420299
subject: Epidemiology not elsewhere classified

description: Excess body weight has been extensively associated with a higher risk of adverse health outcomes and mortality. My PhD examined the association of weight status and weight change with the risk of mortality in community-dwelling older adults. The results of my thesis found that weight change and weight status are important predictors of mortality risk in older adults. These findings underscore the importance of healthcare providers monitoring weight in older adults to detect weight loss in its early stages, enabling more effective interventions aimed at maintaining a stable weight and reducing the risk of premature mortality.
Pompeji in Paris. Die Quatre Saisons (1821) von Eugène Delacroix
Creators: name: Vosskamp, Friederike
Publisher: name: Fondazione Università Ca’ Foscari Venezia, Italia
Year: 2021

description:

The Quatre Saisons by Eugène Delacroix are among the lesser-known and hitherto little-explored works of the French artist. Designed in 1821, the paintings served as decorations for the dining room in the hôtel particulier of the French actor François-Joseph Talma in Paris. Stylistically, the series draws inspiration from ancient art, especially from the Roman wall paintings of Herculaneum and Pompeii that were rediscovered during the eighteenth century. However, rather than imitating models from the past, the artist adapts and rearranges them, thus also revitalising the motif of the four seasons that was very popular for interior decorations in the eighteenth and early nineteenth centuries. The paper discusses Delacroix’s four-part cycle as a striking example of both the rediscovery and appropriation of antiquity in nineteenth-century art. In doing so, it examines the artist’s close relationship with ancient art and the way in which Delacroix draws on models from the past and eclectically transforms them for his own artistic needs. The interest for ancient Roman art is also considered according to the role the patron Talma played in the development of the décor.

Expectation values of chiral primary operators in holographic interface CFT
Creators: name: Nagasaki, Koichi

Publisher: name: arXiv

Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: We consider the expectation values of chiral primary operators in the presence of the interface in the 4 dimensional N=4 super Yang-Mills theory. This interface is derived from D3-D5 system in type IIB string theory. These expectation values are computed classically in the gauge theory side. On the other hand, this interface is a holographic dual to type IIB string theory on AdS_5 x S^5 spacetime with a probe D5-brane. The expectation values are computed by GKPW prescription in the gravity side. We find non-trivial agreement of these two results: the gauge theory side and the gravity side.

description: This paper provides a new proof of a theorem of Chandler-Wilde, Chonchaiya and Lindner that the spectra of a certain class of infinite, random, tridiagonal matrices contain the unit disc almost surely. It also obtains an analogous result for a more general class of random matrices whose spectra contain a hole around the origin. The presence of the hole forces substantial changes to the analysis.
Les chantiers du Louvre et des Tuileries en 1800
Creators: name: Guillaume, Nicoud
Publisher: name: Fondazione Università Ca’ Foscari Venezia, Italia
Year: 2021

description:

In 1800, the “Grand dessein” established under Henri IV that aims at uniting the Louvre and Tuileries palaces was relaunched and the completion of the Cour Carrée was undertaken. Historiographical debates followed, with the idea of understanding better and respecting the ancient parts of these buildings. The result was that the Louvre of Lescot and Goujon could be used as a reference for the construction site, or even for everything that had been built up until Henri IV, but the contribution since Louis XIV took a back seat. This historicizing approach made it possible to finally begin the completion process.
