description: In this paper we present an integrated system developed in order to record, construct, pre-process, manage,
visualize and visually navigate 3D models reality based of large archeological and architectural sites for
eHeritage GIS systems. The framework integrates structured geometrical and documentary information
resulting from multiple sources with the aim to enhance the knowledge of those sites within the frame of its
historical evolution and its institutional management in a 3D GIS/DB. The developed applications were
designed for different types of users, with a largely scalable interface, able to support different output
devices and to work at different levels of iconicity. The system allows a full comprehension of the buildings
in their own context, permitting to discover unknown relationships, to evaluate their architectural occupancy
and to quickly access a complex system of information. The framework has been tested in two different
systems - designed and developed to satisfy both internal (cataloguing, documentation, preservation,
management of archaeological heritage) and external (communication through the web portal) purposes:
the first, in Pompeii, developed in order to have a web-based system that uses Open Source software and
complies with national and international standards; the second one, a prototype designed to make available
on the Google Earth platform the complete Palladian corpus documentation implemented by the CISAAP.

description: Many real-world networks, including social and information networks, are dynamic structures that evolve over time. Such dynamic networks are typically visualized using a sequence of static graph layouts. In addition to providing a visual representation of the network structure at each time step, the sequence should preserve the mental map between layouts of consecutive time steps to allow a human to interpret the temporal evolution of the network. In this paper, we propose a framework for dynamic network visualization in the on-line setting where only present and past graph snapshots are available to create the present layout. The proposed framework creates regularized graph layouts by augmenting the cost function of a static graph layout algorithm with a grouping penalty, which discourages nodes from deviating too far from other nodes belonging to the same group, and a temporal penalty, which discourages large node movements between consecutive time steps. The penalties increase the stability of the layout sequence, thus preserving the mental map. We introduce two dynamic layout algorithms within the proposed framework, namely dynamic multidimensional scaling (DMDS) and dynamic graph Laplacian layout (DGLL). We apply these algorithms on several data sets to illustrate the importance of both grouping and temporal regularization for producing interpretable visualizations of dynamic networks.

The case studies presented belong to the wide repertoire of mosaics of Ravenna, ranging from the byzantine to the modern ones. One of the most peculiar characteristics of mosaics that often limits their digital survey is their multi-scale complexity; nevertheless their models could be used in 3d information systems, for digital exhibitions, for reconstruction aims and to document their conservation conditions in order to conduct restoration interventions in digital environments aiming at speeding and performing more reliable evaluations.

description: Nach dem Zusammenbruch des Gesundheitssystems mit Beendigung des 2. Weltkrieges stand zur Behandlung von erkrankten Kindern in Deutschland nur eine unzureichende Anzahl von Krankenhäusern zur Verfügung. Die konfessionellen Kinderkrankenhäuser konnten in dieser Situation auch in der Sowjetischen Besatzungszone ihre Tätigkeit fortführen bzw. neue Wirkungsstätten gründen. Die Sowjetische Militäradministration Deutschlands hatte die Kirchen mit ihren Wohlfahrtsverbänden Diakonie und Caritas aufgerufen, ihre Tätigkeit unverzüglich wieder aufzunehmen. Auch nach der Gründung der DDR und in deren Entwicklung konnten sie sich, z. T. auch neben staatlichen Kinderkliniken, im atheistischen Staat behaupten. Dies stellte eine Ausnahme innerhalb des Verbundes der sozialistischen Staaten dar. Die Dissertation gibt eine Übersicht über die 10 konfessionellen Kinderkliniken und deren strukturellen und ideellen Charakteristika. Darüber hinaus werden Gründe für ihre Ausnahmestellung erörtert.
description: After World War II the health systems in Germany broke down so that there was only an insufficient number of hospitals available for the treatment of sick children. In this situation the confessional hospitals for sick children were able to continue their work also during the soviet occupying power. Even new hospitals were founded. The Soviet Military Administration of Germany had called upon the churches with their welfare associations like "Caritas" and "Diakonie" for continuing their work immediately. Even after the foundation of the German Democratic Republic (GDR) and during its development confessional hospitals were able to compete with federal hospitals for sick children within an atheist state. This was an exception within the alliance of the socialist states. This dissertation gives a survey about ten confessional hospitals for sick children and their structural and ideal characteristics. In addition, reasons for the exceptional position of these are discussed.

description: The dramatic increase of network infrastructure comes at the cost of rapidly increasing energy consumption, which makes optimization of energy efficiency (EE) an important topic. Since EE is often modeled as the ratio of rate to power, we present a mathematical framework called fractional programming that provides insight into this class of optimization problems, as well as algorithms for computing the solution. The main idea is that the objective function is transformed to a weighted sum of rate and power. A generic problem formulation for systems dissipating transmit-independent circuit power in addition to transmit-dependent power is presented. We show that a broad class of EE maximization problems can be solved efficiently, provided the rate is a concave function of the transmit power. We elaborate examples of various system models including time-varying parallel channels. Rate functions with an arbitrary discrete modulation scheme are also treated. The examples considered lead to water-filling solutions, but these are different from the dual problems of power minimization under rate constraints and rate maximization under power constraints, respectively, because the constraints need not be active. We also demonstrate that if the solution to a rate maximization problem is known, it can be utilized to reduce the EE problem into a one-dimensional convex problem.

description: With the constant increase of transistor power
density, electro thermal modeling is becoming a necessity for
accurate prediction of device electrical performances. For this
reason, this paper deals with a methodology to obtain a precise nonlinear thermal model based on Model Order Reduction of a three dimensional thermal Finite Element (FE) description. 
This reduced thermal model is based on the Ritz vector approach which ensure the steady state solution in every case.
An equivalent SPICE subcircuit implementation for circuit simulation is proposed and discussed. The nonlinear approach of the reduced model is based on the Kirchoff transformation. 
The model has been successfully implemented in a circuit simulator for a PHEMT device.

Song in a hybrid zone between Townsend’s (Setophaga townsendi) and black-throated green (S. virens) warblers
Creators: name: Kenyon, Haley Linnell
Publisher: name: University of British Columbia
Year: 2014

description: Song is one of the most widely recognized premating barriers to reproduction between avian species. In oscines both genetic and cultural inheritance contribute to an individual’s song phenotype, contributing to difficulty in predicting the role that song may play in reproductive isolation; interspecific song learning could promote interbreeding. Here I seek to better understand this phenomenon by studying song in a narrow hybrid zone between black-throated green (Setophaga virens) and Townsend’s warblers (S. townsendi). I use multivariate analyses to compare songs in the hybrid zone to those found in allopatry, predicting that if song is a strong barrier to interbreeding, then there should be a relationship between song and genotype in the hybrid zone. I employ a genotyping-by-sequencing (GBS) method to identify thousands of markers and develop two hybrid indices. Playback experiments were carried out in the field to test responses to parental songs, and a cline analysis was conducted in order to compare transitions in genotype and song across the hybrid zone. I show that only parental song types are found in the hybrid zone, and furthermore, that there is little if any association between song and genotype in sympatric individuals; this suggests that song is not an important reproductive barrier. Allopatric individuals responded only to local songs, indicating that individuals may exhibit a learned response to songs that they are commonly exposed to. Out of thousands of genomic markers, I identified few that were diagnostic, suggesting that much of the genome may introgress freely between these species. I observed discordance between the song and genotype clines; the song cline was much narrower indicating that song is under stronger selection. Taken together, these findings combine to suggest that song is not a reproductive barrier in this hybrid zone, but is instead a cultural trait that is maintained by frequency-dependent selection. Thus, it may be more beneficial for males to sing a locally common song than to broadcast accurate species-membership information.

For the four- and five-dimensional fcc lattices, we give rigorous proofs of the ODEs that were conjectured by Guttmann and Broadhurst. Additionally, we find the ODE of the LGF of the six-dimensional fcc lattice, a result that was not believed to be achievable with current computer hardware.

description: A new MMIC PA for Cellular &
AMPS handsets based on the asymmetric power
combining scheme of Doherty amplifier has been
developed to boost the efficiency at a low power
level. The amplifier has two modes of operation, low
and high power modes. At a low power mode, only
the main amplifier generates output power and at a
high power mode, both the main and auxiliary
amplifiers are operational, combining the power
efficiently by the load modulation. For the CDMA
environment, the amplifier at the low power mode
exhibits PAE of 35% and ACLR less than 31dBc at
18.6dBm and the high power mode exhibits PAE of
37.7% and ACLR of 31dBc at 28.4dBm. For the
AMPS mode operation, the amplifier delivers
21dBm with PAE of 41.7% and 30.3dBm with 43%
in low mode and high mode, respectively.

Universal Angular Probability Distribution of Three Particles near Zero Energy Threshold

description: We study bound states of a 3--particle system in $\mathbb{R}^3$ described by the Hamiltonian $H(λ_n) = H_0 + v_{12} + λ_n (v_{13} + v_{23})$, where the particle pair $\{1,2\}$ has a zero energy resonance and no bound states, while other particle pairs have neither bound states nor zero energy resonances. It is assumed that for a converging sequence of coupling constants $λ_n \to λ_{cr}$ the Hamiltonian $H(λ_n)$ has a sequence of levels with negative energies $E_n$ and wave functions $ψ_n$, where the sequence $ψ_n$ totally spreads in the sense that $\lim_{n \to \infty}\int_{|ζ| \leq R} |ψ_n (ζ)|^2 dζ= 0$ for all $R>0$. We prove that for large $n$ the angular probability distribution of three particles determined by $ψ_n$ approaches the universal analytical expression, which does not depend on pair--interactions. The result has applications in Efimov physics and in the physics of halo nuclei.

Employing linear Zeeman effect and optical Stark shift, two spin states within the ground electronic manifold are selected, which results in a pseudo-spin-1/2 model. We further study the ground state structures of a spin-orbit-coupled Cr condensate. We show that, in addition to the stripe structures induced by the spin-orbit coupling, the magnetic dipole-dipole interaction gives rise to the vortex phase, in which spontaneous spin vortex is formed.

description: A low-cost, low-current consumption 2.4-
2.5GHz MMIC power amplifier operating at 3.3V single
supply has been developed for high data rate, wide-range
portable WLAN applications. The MMIC utilizes a
Fairchild-proprietary InGaP HBT process that enables the
design of high power density and extremely linear circuits
at frequencies exceeding 6GHz. The MMIC design has been
constructed based on accurate HBT and passives models,
focusing on performance optimization for low AM-AM and
AM-PM distortion, low current consumption and minimal
harmonic levels. For an OFDM modulated signal at 54Mbps
data rate, the PA delivers +23.6 dBm linear output at a
corresponding Error Vector Magnitude (EVM) of 4.4%(-27dB), while consuming an average packet current of less
that 315mA. The MMIC is fully matched in a cost-effective
3x3mm QFN package, requiring only a small number of

description: A 2W HiVP power amplifier for GSM
mobile communication system is designed using 0.12-µm
CMOS process. To solve the problem of low breakdown
voltage in deep-submicron CMOS technology, the new High
Voltage/High Power (HiVP) device configuration is used.
With HiVP configuration, a large voltage can be divided by
several devices, so that the voltage drop on each device is
reduced. Hence the low-cost CMOS technology can be
adopted for the design of power amplifier which will be used
in a mobile phone. In this paper, an analytical overview of
theory and practice of the HiVP power amplifier are
discussed.

description: We provide optimal rates of convergence to the asymptotic distribution of the (properly scaled) degree of a fixed vertex in two preferential attachment random graph models. Our approach is to show that these distributions are unique fixed points of certain distributional transformations which allows us to obtain rates of convergence using a new variation of Stein's method. Despite the large literature on these models, there is surprisingly little known about the limiting distributions so we also provide some properties and new representations, including an explicit expression for the densities in terms of the confluent hypergeometric function of the second kind.

Development of heteroatom radical based synthetic strategies

Publisher: name: University of British Columbia

description: This thesis presents investigations of carbo- and heterocycle formation using radical relay cyclization reactions initiated by alkoxy radicals, cyclic imine formation using substoichiometric stannane and photodeoxygenation reactions involving benzotriazole-borane complexes. Chapter 1 describes our investigations and development of radical relay cyclization reactions initiated by alkoxy radicals that provided carbo- and heterocyclic compounds. Pairing N-alkoxyphthalimides as alkoxy radical precursors with the slow addition of radical initiator provided a wide range of carbocycles. Incorporation of functionality into the linear backbone provided substituted heterocyclic compounds in excellent yield. Chapter 2 describes the cyclization of aminyl radicals onto silyl enol ethers. The rate acceleration imparted by the silyl enol ether allowed for high yielding pyrrolidine formation. Investigations focused on an unexpected cyclic imine product that was observed in our previous studies. We sought to both optimize our conditions to provide this imine in the highest possible yield, and investigated the mechanism by which this imine product may be formed. Chapter 3 describes the development of a photodeoxygenation reaction using benzotriazole-borane complexes. The coordination of a benzotriazole ligand with commercially available borane-tetrahydrofuran provides the benzotriazole-borane complex as a bench stable white powder. DFT calculations suggested these benzotriazoleborane complexes could behave a radical chain deoxygenation reaction. Irradiation of a variety of xanthates provided the deoxygenated products in excellent yield. Furthermore, our work suggests that the benzotriazole ligand may be catalytic in these deoxygenation reactions.

description: A gold-free, fully Cu metallized
InGaP/GaAs HBT using platinum as the diffusion barrier
has been successfully fabricated. The HBT uses Pd/Ge for ntype, Pt/Ti/Pt/Cu for p+type ohmic contacts, and Ti/Pt/Cu
for interconnect metals with platinum as the diffusion
barrier. The Ti/Pt/Cu structure was stable up to 350  
annealing as judged from the data of XRD and sheet
resistance. Current accelerated stress test was conducted on
the device with current density JC=140 kA/cm2 for 24 hours,
the current gain showed no degradation. The devices were
also thermally annealed at 250  for 24 hours and showed
little changes. We have successfully demonstrated that Aufree, fully Cu metallized HBT can be achieved by using Pt as
the diffusion barrier and Pd/Ge and Pt/Ti/Pt/Cu as the
ohmic contacts.

description: Two monolithic matrix amplifiers for ECM
and ESM military equipment have been designed and
realized using 0.25  m GaAs PHEMT technology from
UMS. Design trade-offs and performances are discussed
detail. The effects of the biasing network, termination load
and total gate periphery on the performance of the
amplifiers were considered for optimum design. The first
amplifier , designed for gain flatness and noise figure yields
gain of 19   1 dB and a typical noise figure of 4 dB. The
second unit exhibits a positive linear gain slope from 16 dB
to 20 dB. Output power at 1 dB compression point is +12
dBm. The die size and bandwidth of each MMIC is 7 mm2
and 0.5-20 GHz respectively.
Field evidence for the upwind velocity shift at the crest of low dunes

description: Wind topographically forced by hills and sand dunes accelerates on the upwind (stoss) slopes and reduces on the downwind (lee) slopes. This secondary wind regime, however, possesses a subtle effect, reported here for the first time from field measurements of near-surface wind velocity over a low dune: the wind velocity close to the surface reaches its maximum upwind of the crest. Our field-measured data show that this upwind phase shift of velocity with respect to topography is found to be in quantitative agreement with the prediction of hydrodynamical linear analysis for turbulent flows with first order closures. This effect, together with sand transport spatial relaxation, is at the origin of the mechanisms of dune initiation, instability and growth.

Eikonal Approach to N=4 SYM Regge Amplitudes in the AdS/CFT Correspondence

description: The high-energy behavior of N=4 SYM elastic amplitudes at strong coupling is studied by means of the AdS/CFT correspondence. We consider the eikonal method proposed by Janik and one of the authors, where the relevant minimal surface is a "generalized helicoid" in hyperbolic space ("Euclidean AdS_5"), from which the physical amplitude is obtained after an appropriate analytic continuation. We then compare our results with those obtained, using a minimal surface in AdS_5 momentum space, by Alday and Maldacena for gluon-gluon scattering, and by Barnes and Vaman for quark-quark scattering ("Alday-Maldacena approach"). Exploiting a conformal transformation, we show that the eikonal amplitudes are dominated by the Euclidean version of the cusp contribution found in the Alday-Maldacena approach. The amplitudes in the two approaches are of Regge type at high-energy and with the same logarithmic Regge trajectory independently of the kind of colliding particles, in agreement with the expected universality of Regge trajectories.

Rolle der humanen PIWIL-Gene bei der Spermatogenese und der männlichen Infertilität

description: Ungewollte Kinderlosigkeit betrifft in Deutschland etwa 15 % aller Paare. Obwohl männliche Infertilitätsfaktoren gut untersucht sind, bleibt die Ursache in mehr als 30% der Fälle unklar. Ziel der Arbeit ist es, die Bedeutung der PIWIL-Gene für die männliche Keimzellentwicklung und assoziierter Infertilität zu untersuchen. In ejakulierten Spermatozoen war eine erhöhte mRNA-Expression von PIWIL1 mit verringerter Motilität und Vitalität assoziiert. Eine reduzierte mRNA-Expression von PIWIL2 war mit reduzierter Gesamtspermienzahl verknüpft. Im Weiteren wurde gezeigt, dass die humanen PIWIL-Gene 1-4 über DNA-Methylierung regulierbar sind. Für PIWIL2 wurde ein direkter Zusammenhang zwischen geringer Promotormethylierung und verstärkter Expression in vitro gezeigt. Weiterhin wurden Promotorbereiche identifiziert, welche für die Transkriptionskontrolle von PIWIL2 entscheidend sind. In knockdown-Studien wurde gezeigt, dass die PIWIL-Gene 1 und 2 Einfluss auf die Expression von Genen haben, die für die Spermatogenese unablässig sind. Der Verlust von PIWIL1 und PIWIL2 hatte Konsequenzen auf Proliferation, Vitalität und Apoptose.
description: Unintended childlessness affects about 15% of all couples in Germany. Although male infertility factors are well studied, the cause remains unclear in more than 30% of cases. The aim of this work is to investigate the importance of PIWIL for spermatogenesis and associated infertility. In ejaculated spermatozoa, increased mRNA expression of PIWIL1 was associated with decreased motility and vitality. Reduced mRNA expression of PIWIL2 was associated with reduced total sperm count. Furthermore, it was shown that the human PIWIL genes 1-4 can be regulated by DNA methylation. For PIWIL2 a direct correlation between low promoter methylation and increased expression in vitro was shown. Furthermore, promoter regions were identified which are crucial for the transcriptional control of PIWIL2. In knockdown studies, PIWIL genes 1 and 2 have been shown to influence the expression of genes that are crucial for spermatogenesis. The loss of PIWIL1 and PIWIL2 had consequences for proliferation, vitality and apoptosis.

description: This paper describes the realization of a
Chireix power combining part of an outphasing system for
2.14 GHz consisting of two saturated class-B power
amplifiers and a Chireix power combiner circuit. The
Chireix power combining scheme can be used in Chireix
outphasing architecture, which is currently together with
EER and the Doherty amplifier one of the most prominent
research topics in power amplifier linearization / efficiency
enhancement area.
In an outphasing system, also known as LINC (Linear
Amplification of Nonlinear Components), an amplitude and
phase modulated signal is separated into two constant
envelope signals containing only phase modulation. The
original signal waveform can subsequently be reconstructed
by varying the phases of the two constant envelope signal
branches, thus enabling, ideally, linear amplification of the
original signal with system efficiency comparable to the
efficiency of the used PAs.
In this paper, the design and implementation as well as
the measurement results of a microstrip-line Chireixcombiner
together with saturated class-B pHEMT power
amplifiers for WCDMA downlink band 2.11-2.17 GHz are
reported. The measurement results verify that the concept
is indeed functional, and significant efficiency improvement
over traditional power combining can be attained. At peak
envelope power 37.4 dBm system efficiency of 77 % was
measured, and at –8 dB back-off, representing the
computational average point for WCDMA signal, system
efficiency of 43 % was measured.
