description: Anthropogenic climate change, accelerating the melting glaciers and ice sheets resulting in future sea level rise, is a key concern for humanity. Over the past 700 thousand years, glacial-interglacial cycles have shaped Earth’s climate. These are marked by relatively large, at times rapid system changes. As such, the past offers an albeit fuzzy perspective on possible ice and climate system interactions and transitions. Constraints on ice-climate evolution beyond the Last Glacial Maximum, however, are sparse, and dating uncertainties increase with geologic time. Given the data limitations, the paleo community often looks to models to complement inferences from paleodata. Still, to date, no full glacial cycle simulations have been published with coupled ice and climate models of sufficient complexity to resolve synoptic scale atmospheric dynamics and ocean circulation. This thesis explores the phase space of model simulations of transient ice-climate co-evolution in response to radiative forcing during the last two glacial cycles. The novelty of our study lies in three key aspects. Firstly, we employ LCice, a fully coupled Earth system model of intermediate complexity, which incorporates all key ice-climate feedbacks. Secondly, we utilize ensemble simulations instead of a single model realization. This approach moves beyond attempting to recreate the past as closely as possible with always imperfect models. It instead offers an exploration of plausible physically-self consistent scenarios. Thirdly, our study includes transient simulations of the last two glacial cycles, encompassing both ice growth and retreat phases. This thesis documents the following contributions: 1) a detailed analysis of the potential phase space of the last two glacial inceptions, 2) a continuous record of climate fields derived from ensemble simulations across the last two glacial cycles, and 3) an analysis of the relative impact of the ice-climate feedbacks on ice evolution during the last glacial cycle.

description: We continue the analysis of BPS bounds started in arXiv:1110.2688, extending it to the full class of N=2 gauged supergravity theories with arbitrary vector and hypermultiplets. We derive the general form of the asymptotic charges for asymptotically flat (M_4), anti-de Sitter (AdS_4), and magnetic anti-de Sitter (mAdS_4) spacetimes. Some particular examples from black hole physics are given to explicitly demonstrate how AdS and mAdS masses differ when solutions with non-trivial scalar profiles are considered.

description: The authors present an analytic, empirical largesignal model for the efficient simulation of Hetero Field Effect Transistors. The model has been extracted and verified for a 0.15µm AlGaAs/InGaAs/GaAs pHEMT as well as for a 0.2µm InP/InGaAs/InP pHEMT technology. It uses a new set of chargeconservative capacitance expressions as well as a dispersion model for accurate description of both static and dynamic IV characteristics. A large voltage regime is covered, ranging from the sub-threshold to forward gate conduction and linear to saturation operating regions. Typical HFET effects like self-heating, gain compression, impact ionization as well as particularities of capacitance characteristics are included. Model verification is carried out for static IV, high-frequency S-parameters as well as one- and two-tone power measurements at microwave frequencies for both types of transistors.

recently attracted much interest, some sensitive material
parameters are still uncertain. We detailed the simulation
methodology used to evaluate bandgap energy, minority
carrier lifetime and band gap narrowing effect. Moreover,
the high-injection effect is analysed as resulting from
electron parasitic barrier formation at base-collector
junction.

Evaluation of trace metal distributions (arsenic, cadmium, lead) and lead sources in sediments from a sound and an inlet on the west coast of Vancouver Island, British Columbia
Creators: name: Ikehata, Mariko

description: Barkley Sound and Alberni Inlet, located on the west coast of Vancouver Island, British Columbia, are home to economically important oyster farms. The headwaters of Alberni Inlet are proximal to the city of Port Alberni, where industrial activities (e.g., paper mills, recycling plants) release significant quantities of heavy metals into Alberni Inlet annually. The distribution of As, Cd, and Pb and Pb isotopic composition of Pb were studied in surface and cored sediments collected downstream from the paper mill using quadrupole and multi collector inductively coupled plasma mass spectroscopy (Q-ICP-MS, MC-ICP-MS). Surface and core sediment concentrations of As, Cd and Pb generally decrease downstream from Port Alberni, with the exception of a Pb spike observed in Barkley Sound. Alberni Inlet and Barkley Sound display ranges of 3.8-24 and 3.5-21.6 ppm for As, from 0.03-0.87 and 0.2-1.1 ppm for Cd, and 4.1-18 and 2.9-24.2 ppm for Pb, respectively. Scavenging of dissolved metals is observed at the distance of 10-25 km downstream from Port Alberni. Based on comparison to Sediment Quality Guidelines, the environmental impact of trace metals in the sediment on bottom dwelling organism is low. Major elements compositions determined using Aluminum as an elemental normalizer indicated that the sediment corresponds to a source predominantly from Vancouver Island bedrock. The isotopic composition for surface sediment ranges from 1.17020 to 1.21602 for ²⁰⁶Pb/²⁰⁷Pb, and 2.0397 to 2.0835 for ²⁰⁸Pb/²⁰⁶Pb. In core samples, the range is from 1.16571 to 1.19109 for ²⁰⁶Pb/²⁰⁷Pb and 2.06883 to 2.08533 for ²⁰⁸Pb/²⁰⁶Pb. Lead isotope fingerprinting indicates that sediments derived from Vancouver Island were contaminated with trace metals by a source displaying the Pb isotopic signature of the Sullivan Ore, the primary anthropogenic Pb source for British Columbia. This is consistent with paper mill effluent from Port Alberni. Sediments from the lower inlet and Barkley Sound also show a contribution from Chinese loess. Other human activities are most likely responsible for the spike in Pb concentrations in Barkley Sound. This study demonstrates that the combination of trace metal analysis and high precision Pb isotopic data are effective tools for monitoring anthropogenic input into the environment.

description: p0071 ist ein Mitglied der p120-Catenin-Unterfamilie der Armadillo-Proteine. Die p120-Catenine sind essentielle Regulatoren der Zell-Zell-Adhäsion. Neben einer Assoziation mit Zell-Zell-Kontakten sind diese Proteine auch im Zytoplasma und im Zellkern zu finden, was auf zu-sätz-liche Funktionen in verschiedenen zellulären Signalwegen hinweist. Für p0071 konnte in dieser Arbeit eine bisher unbekannte Funktion bei der Aktomyosin-vermittelten Einschnürung sich teilender Zellen gezeigt werden. Dabei ist p0071 an der lokali-sierten Aktivierung von RhoA beteiligt. Die Regulation der RhoA-Aktivität erfolgt sowohl über eine Interaktion von p0071 mit RhoA als auch über eine physikalische und funktionelle Asso-ziation von p0071 mit ECT2, dem für die Zytokinese essentiellen RhoA-Guanin-Nukleotid-Austauschfaktor. Die in dieser Arbeit vorgestellten Ergebnisse geben Anlass zu der Vermutung, dass p0071 ebenfalls an der Fusion von Rab11-Vesikeln mit der Plasmamembran am Zentralkörper beteiligt ist. p0071 interagiert sowohl mit Rab11 als auch dem t-SNARE-assoziierten Protein Snapin, dessen verringerte Expression, wie die verringerte p0071-Expression, eine Akkumulation von Rab11 um den Zentralkörper verursacht. Des Weiteren konnte gezeigt werden, dass die Lokali-sation und die Funktionen von p0071 während der Zytokinese von dem Mikrotubuli-assoziiertem Motorprotein Kif3b abhängen.

description: Understanding the mechanisms responsible for the equilibration of isolated quantum many-body systems is a long-standing open problem. In this work we obtain a statistical relationship between the equilibration properties of Hamiltonians and the complexity of their eigenvectors, provided that a conjecture about the incompressibility of quantum circuits holds. We quantify the complexity by the size of the smallest quantum circuit mapping the local basis onto the energy eigenbasis. Specifically, we consider the set of all Hamiltonians having complexity C, and show that almost all such Hamiltonians equilibrate if C is super-quadratic with the system size, which includes the fully random Hamiltonian case in the limit C to infinity, and do not equilibrate if C is sub-linear. We also provide a simple formula for the equilibration time-scale in terms of the Fourier transform of the level density. Our results are statistical and, therefore, do not apply to specific Hamiltonians. Yet, they establish a fundamental link between equilibration and complexity theory.

description: This paper emphasizes for the first time the
link existing between some small-signal power gain circles
and the output load of maximum power in GaAs HBTs. We
use the locus of power gain, named Minimum Conjugate-
Termination Power, which have the value MSG/2K. MSG is
maximum stable gain and K the stability factor. 
This method has been applied to the measurements by load-pull of 30W S-Band HBT power bar. By varying the bias of the
amplifier, it is possible using only S-parameters data to
localize accurately and quickly the locus of the power load.

description: Sagittarius A*, the super-massive black hole at the center of the Milky Way, is surrounded by a small cluster of high velocity stars, known as the S-stars. We aim to constrain the amount and nature of stellar and dark mass associated with the cluster in the immediate vicinity of Sagittarius A*. We use near-infrared imaging to determine the $K_\mathrm{s}$-band luminosity function of the S-star cluster members, and the distribution of the diffuse background emission and the stellar number density counts around the central black hole. This allows us to determine the stellar light and mass contribution expected from the faint members of the cluster. We then use post-Newtonian N-body techniques to investigate the effect of stellar perturbations on the motion of S2, as a means of detecting the number and masses of the perturbers. We find that the stellar mass derived from the $K_\mathrm{s}$-band luminosity extrapolation is much smaller than the amount of mass that might be present considering the uncertainties in the orbital motion of the star S2. Also the amount of light from the fainter S-cluster members is below the amount of residual light at the position of the S-star cluster after removing the bright cluster members. If the distribution of stars and stellar remnants is strongly enough peaked near Sagittarius A*, observed changes in the orbital elements of S2 can be used to constrain both their masses and numbers. Based on simulations of the cluster of high velocity stars we find that at a wavelength of 2.2 $μ$m close to the confusion level for 8 m class telescopes blend stars will occur (preferentially near the position of Sagittarius A*) that last for typically 3 years before they dissolve due to proper motions.

description: In der akuten Promyelozytenleukämie (APL) führt das onkogene Fusionsprotein PML/RARα zum Block der Granulopoese im Stadium der Promyelozyten. Durch die Behandlung mit pharmakologischen Dosen all-trans Retinsäure (ATRA) wird die Differenzierung wieder hergestellt. Der microRNA-vermittelte posttranskriptionelle silencing-Mechanismus ist nachweislich in die APL-Entstehung involviert. In der Arbeit konnte gezeigt werden, dass die ATRA-induzierte Differenzierung von APL-Blasten zur Repression der PML/RARα-abhängigen Expression des miR-181a/miR-181b-Clusters führt. In vitro-Untersuchungen belegten die funktionelle Relevanz der beiden miRNAs in der APL. In mechanistischen Untersuchungen konnte die direkte Bindung des microRNA-Clusters an die 3´UTR des Tumorsuppressors RASSF1A gezeigt werden. Durch die Modulation des Zellzyklusregulators Cyclin D1 nehmen RASSF1A und das miR-181a/miR-181b-Cluster essentielle Funktionen in der APL und der ATRA-abhängigen Granulopoese ein.
description: In acute promyelocytic leukemia (APL), the oncogenic fusion protein PML/RARα causes the block of differentiation at promyeolocytic stage. Pharmacologic doses all-trans retinoic acid (ATRA) restore differentiation. The microRNA-mediated silencing process is shown to be important in the formation process of APL. In this work, ATRA leads to the repression of the PML/RARα-dependent miR-181a and miR-181b expression. In vitro studies showed the functional relevance of the microRNA cluster in APL. Mechanistic studies proved the direct binding of the two microRNAs to the 3´UTR of the tumorsuppressor RASSF1A. Finally, it could be shown that RASSF1A and the miR-181a/miR-181b cluster exert essential functions in APL and ATRA-induced differentiation by modulation of the cell cycle regulator Cyclin D1.

description: This paper deals with the development of an etch recipe for the etching of InP by Reactive ion etching (RIE), a vital process step in the fabrication of microstructures. RIE is a dry etching scheme, wherin effective pattern transfer can be achieved due to its inherent anisotropic characteristics for certain process conditions. RIE is preferred to other dry etching schemes since it is simple, robust and is widely used in industry. The main aim of our research is to design micromechanically tunable optical filters for wavelength division multiplexing (WDM) systems. In this system, transmission takes place in the second and third optical communication window, namely in the region of zero material dispersion (1300 nm) and minimum attenuation (1550 nm) respectively. InP based devices are widely used for this application since they are compatible with the above mentioned WDM transmission wavelengths. The key properties investigated in this thesis were the material etch rate, the selectivity of the material with res  to the mask, the side wall steepness and the surface morphology. The examined process parameters have been the rf-power, the flow rate, the pressure inside the chamber, the substrate temperature and the various ratios of gas combinations. Improved values of etch rate and selectivity have been achieved with respect to past results by optimizing the process conditions. Etch rates as high as 120 nm/min have been achieved using CH4 / H2 with infinite values of selectivity for certain process parameters. Measurements have also been made on InP samples using the scanning electron microscope and the atomic force microscope for determining the side wall steepness and the roughness of the etched surface. Side wall slopes close to 90° and surface roughnesses below 0.4 nm (rms) have been achieved. The earlier reported problems of polymer deposition on top of the mask was strongly suppressed. In addition measurements have been carried out on various samples to establish process stability, an absolute necessity for realis vel recipe.

description: We show that the space of generalized fluxes - momentum space - for loop quantum gravity cannot be constructed by Fourier transforming the projective limit construction of the space of generalized connections - position space - due to the non-abelianess of the gauge group SU(2). From the abelianization of SU(2), U(1)^3, we learn that the space of generalized fluxes turns out to be an inductive limit, and we determine the consistency conditions the fluxes should satisfy under coarse-graining of the underlying graphs. We comment on the applications to loop quantum cosmology, in particular, how the characterization of the Bohr compactification of the real line as a projective limit opens the way for a similar analysis for LQC.

description: The Sagnac effect is a time or phase shift observed between two beams of light traveling in opposite directions in a rotating interferometer. We show that the standard description of this effect within the framework of general relativity misses the effect of deflection of light due to rotational inertial forces. We derive the necessary modification and demonstrate it through a detailed analysis of the square Sagnac interferometer rotating about its symmetry axis in Minkowski space-time.

description: We present a novel self-consistent time-domain model for the analysis and design of traveling-waveelectroabsorption modulators (TW-EAMs). The model fully accounts for the nonlinear interaction betweenthe microwave and optical traveling fields. The effects on the bandwidth and modulation efficiency of the nonuniform optical field distribution along the device are discussed. A few examples of application are presented, showing the model to be an efficient tool for the analysis, design and optimization of TW-EAMs for analog and digital applications.

description: We study the spectra of neutron-rich oxygen isotopes based on chiral two- and three-nucleon interactions. First, we benchmark our many-body approach by comparing ground-state energies to coupled-cluster results for the same two-nucleon interaction, with overall good agreement. We then calculate bound excited states in 21,22,23O, focusing on the role of three-nucleon forces, in the standard sd shell and an extended sdf7/2p3/2 valence space. Chiral three-nucleon forces provide important one- and two-body contributions between valence neutrons. We find that both these contributions and an extended valence space are necessary to reproduce key signatures of novel shell evolution, such as the N = 14 magic number and the low-lying states in 21O and 23O, which are too compressed with two-nucleon interactions only. For the extended space calculations, this presents first work based on nuclear forces without adjustments. Future work is needed and open questions are discussed.

description: In this thesis, we investigate the use of biosensor arrays for detection of molecular species in dynamical fluid systems. First, we construct dynamical models for the transport of target molecules in a fluid over an array of surface-based biosensors. Using multiple time and length scales in the system dynamics, we develop a novel approximate model for the system. The derived model is an extension of the two-compartment model, which is used in the analysis of mass-transfer binding experiments. Then, we investigate how measurements of multiple biosensors can improve the estimation of target molecule concentration in a mass transfer system. The estimation problem is solved as a nonlinear least squares problem based on the derived model. The properties of the finite-sample estimator is investigated by deriving analytic expressions and Monte Carlo simulations. As an example, the results are illustrated for a protein-based biosensor. Second, we address the problem of detecting minute concentrations (nano to pico-molar) of target molecules with a single sensor. It is shown that substantial improvements in the response rate can be obtained by distributing the sensing surface area to form an array of spaced smaller sensors while the total sensing area remains fixed. The output signals of the individual sensors in the array are combined to form a single output signal for measurements. Formulas are derived for quantifying the improvement of the array response and for optimizing the size of the sensors. The analytical results are compared with experimental data for a protein-based biosensor and a surface plasmon resonance biosensor. Finally, we construct a mathematical proof for the accuracy of the two-compartment model, which is the basis of most of our analyses.

description: Electrical spin injection into semiconductors paves the way for exploring new phenomena in the area of spin physics and new generations of spintronic devices. However the exact role of interface states in spin injection mechanism from a magnetic tunnel junction into a semiconductor is still under debate. In this letter, we demonstrate a clear transition from spin accumulation into interface states to spin injection in the conduction band of $n$-Ge. We observe spin signal amplification at low temperature due to spin accumulation into interface states followed by a clear transition towards spin injection in the conduction band from 200 K up to room temperature. In this regime, the spin signal is reduced down to a value compatible with spin diffusion model. More interestingly, we demonstrate in this regime a significant modulation of the spin signal by spin pumping generated by ferromagnetic resonance and also by applying a back-gate voltage which are clear manifestations of spin current and accumulation in the germanium conduction band.

description: The high frequency, high power performance of a modulator driver based on a dual input travelling wave amplifier (combiner) is reported. Measured output terminal voltages greater than 7 Vpp have been achieved. Although the results are intermediate in some respect, the simulated as well as the measured data indicate that the driver circuit is suitable for a bit rate of 40 Gbit/s. Simulation results obtained for an improved circuit which contains an active divider also indicate even better performance at operation with single input voltage.

description: In der vorliegenden Arbeit wurde der Einfluss einer Strahlentherapie auf das Lymphgefäßsystem der menschlichen Haut untersucht. Aufgrund von Vorarbeiten, bei denen eine Hyperplasie von Lymphkapillaren nach einer Strahlentherapie in der Haut festgestellt wurde, tat sich die Frage nach den Pathomechanismen auf. Ziel dieser Arbeit waren Veränderungen des Lymphgefäßwachstum in humaner Haut nach Bestrahlung im Zusammenhang mit Makrophagen und VEGF-C-Expression zu untersuchen. Von 40 Patienten wurden nach einer abgeschlossenen Strahlentherapie (50Gy, äquivalente Hautdosis 30-35Gy) Hautproben aus der vorderen Axillarlinie im bestrahlten Areal und dem kontralateralen unbestrahlten Areal entnommen. Davon angefertigte Schnitte wurden immunhistochemisch mit CD68- und VEGF-C-Antikörper untersucht. Die Bestimmung der Dichten der CD68-positiven Zellen und der VEGF-C-positiven Zellen ergaben eine signifikant höhere Anzahl in dem bestrahlten Gebiet im Vergleich zu dem unbestrahlten Gebiet. Die Bestrahlung stellt für die Lymphgefäße eine Belastung dar, da einerseits vermehrt Zelldetritus und aus dem Verband gelöste Zellen anfallen und andererseits der Lymphstrom infolge eines durch die Blutkapillarschädigung verursachten gesteigerten interstitiellen Flüssigkeits- und Proteingehaltes verstärkt werden muss. Dies erfordert eine vermehrte Resorption und Transportfunktion. In Folge einer Bestrahlung mit 50Gy (30-35Gy äquivalente Hautdosis) kommt es zu einer Erhöhung der Makrophagendichte im oberen horizontalen dermalen Gefäßplexus, wovon ein Teil VEGF-C auf ihrer Oberfläche expremieren. VEGF-C als ein Wachstumsfaktor für Lymphgefäße kann daraufhin die Lymphangiogenese aktivieren.
description: In this study we analysed the influence of radiation therapy on the lymph system of the human skin. Previously studies showed a hyperplasia of lymph vessels after radiation therapy. The aim of this study was on identifying the patho-mechanism of this lymph angiogenesis in relation to macrophages and VEGF-C-expression. 80 skin biopsies from 40 patients were taken from irradiated skin and the corresponding contra-lateral un-irradiated control area after a standard radiotherapy with 6 MV photons via tangential fields (50 Gy, skin equivalent dose 30-35 Gy). These samples were stained with CD68- und VEGF-C-antibodies. We found a high increase of the numbers of CD68+ and VEGF-C+ cells in irradiated skin. Thus, our results indicate that VEGF-C expression by invading macrophages could be a patho-genetic route of induction of radiogenic lymph angiogenesis after a radiation therapy.

description: A 3-stage dual TransImpedance Amplifier (TIA) on one 2x1.8 mm 2 GaAs chip with 0.2 µm pHEMT technology has been designed for fiberoptic communication applications. It uses cascode connected common source FETs in a Constant-K configuration. The operating frequency ranges from DC to 35 GHz. The TIA is designed for a diode capacitance of 120 fF. The equivalent input referred noise current is around 18 pA/ÖHz for a gain of around 40 dBW or 6.5 dB. The matching at the output is better than 14 dB. Measured RF performance in combination with the small size makes it very suitable for WDM telecommunication systems. A comparison between simulations and measurements is also made.

description: We present an efficient simulation technique to account for the thermal spreading effects of surface metallizations in the self-consistent dynamic electro-thermal analysis of power microwave devices. Electro-thermal self-consistency is achieved by solving the coupled nonlinear system made of a temperature dependent device electrical model, and of an approximate description of the device thermal behavior through a thermal impedance matrix. The numerical solution is pursued in the frequency domain by the Harmonic Balance technique. The approach is applied to the thermal stability analysis of power AlGaAs/GaAs HBTs and the results show that metallizations have a significant impact on the occurrence of the device thermal collapse.

description: An analytical treatment for the stability of Resonant Tunneling devices is proposed. It exploits a previously proposed approach for Resonant Tunneling Diodes with the aim of deriving an effective guideline for the use of such class of devices in MMIC applications. The discussion is carried out on a class of devices deriving from the integration of Heterojunction Interband Tunneling Diodes (HITD) with HEMTs on an InP substrate, for different cases of device parameters uncertainty and circuit topologies. Preliminary simulations and experimental validation results are provided in the paper.

description: The role of magnetic and electric perturbations to the quantum Lifshitz model in 2+1 dimensions are examined in this paper. The quantum Lifshitz model is an effective field theory for quantum multicritical systems, that include generalized 2D quantum dimer models in bipartite lattices and their generalizations. It describes a class of quantum phase transitions between ordered and topological phases in 2+1 dimensions. Magnetic perturbations break the dimer conservation law. Electric excitations, whose condensation lead to ordered phases, have been studied extensively both in the classical 3D model and in the quantum 2D model. However, the role of magnetic vortex excitations whose condensation drive these systems into a $\mathbb{Z}_2$ topological phase has been largely ignored. To study the interplay of both excitations, we perform a perturbative renormalization group study to one loop order and study the stability of the theory away from quantum multi criticality. This is done by generalizing the operator product expansion to anisotropic models. The relation with recent classical Monte Carlo simulations in Rokhsar-Kivelson wave functions will be discussed.
