description: We propose a unified mathematical scheme, based on a classical tensor isomorphism, for characterizing entanglement that works for pure states of multipartite systems of any number of particles. The degree of entanglement is indicated by a set of absolute values of the determinants for each subspace of the multipartite systems. Unlike other schemes, our scheme provides indication of the degrees of entanglement when the qubits are measured or lost successively, and leads naturally to the necessary and sufficient conditions for multipartite pure states to be separable. For systems with a large number of particles, a rougher indication of the degree of entanglement is provided by the set of mean values of the determinantal values for each subspace of the multipartite systems.

description: Currently, the thin film microwave multi-chip module (MCM) technology offers many benefits for a compact, lightweight and low cost integration of RF and microwave circuits [see Carchon et al (1)]. This technology allows the realisation of low loss transmission lines with a variety of characteristic impedances (between 10 and 100 Ohm) up to the higher mm-wave frequencies (>50 GHz). The technology also allows mounting active circuits (such as MMICs) by e.g. flip-chip technology. However, when placing different functions closely together, an adequate shielding and also mechanical protection of the active dies may be required. For this purpose, we developed a wafer level (called 0- level) package concept using micromachined cavities to realise versatile, microwave compatible protection and shielding structures on the thin film substrate. 0-level packaging refers to packaging before separation of the dies of the thin film integration substrate. In order to illustrate this concept and the benefits in real microwave functions, the realisation of a Ka-band LNA module, including 0-level package, bias circuits and RF feedthrough structures is discussed in this contribution.
Adaptive functional linear regression

Subjects: subject: Statistics Theory (math.ST)

description: We consider the estimation of the slope function in functional linear regression, where scalar responses are modeled in dependence of random functions. Cardot and Johannes [J. Multivariate Anal. 101 (2010) 395-408] have shown that a thresholded projection estimator can attain up to a constant minimax-rates of convergence in a general framework which allows us to cover the prediction problem with respect to the mean squared prediction error as well as the estimation of the slope function and its derivatives. This estimation procedure, however, requires an optimal choice of a tuning parameter with regard to certain characteristics of the slope function and the covariance operator associated with the functional regressor. As this information is usually inaccessible in practice, we investigate a fully data-driven choice of the tuning parameter which combines model selection and Lepski's method. It is inspired by the recent work of Goldenshluger and Lepski [Ann. Statist. 39 (2011) 1608-1632]. The tuning parameter is selected as minimizer of a stochastic penalized contrast function imitating Lepski's method among a random collection of admissible values. This choice of the tuning parameter depends only on the data and we show that within the general framework the resulting data-driven thresholded projection estimator can attain minimax-rates up to a constant over a variety of classes of slope functions and covariance operators. The results are illustrated considering different configurations which cover in particular the prediction problem as well as the estimation of the slope and its derivatives. A simulation study shows the reasonable performance of the fully data-driven estimation procedure.

Roadmap to ethnic strife : economic reform in Myanmar and enduring conflict in the Kachin region
Creators: name: McLeod, Kevin
Publisher: name: University of British Columbia
Year: 2013

description: In 2011, fighting resumed between the Kachin Independence Army and the Myanmar military in the Kachin region of Myanmar. This fighting came after Myanmar established and carried out its “Roadmap to Democracy,” after the new Constitution in 2008 was ratified, and after the first elections in twenty years took place. In light of these reforms, why has fighting reignited now when western observers display more optimism for the future of Myanmar than ever before? This paper intends to illustrate that the competition over access to the economic flows of the Kachin region is fuelling this eruption of military conflict. What is more, Myanmar’s economic transition to a liberalized economy favours persistent tensions in the Kachin province. Since the rapid economic liberalisation of the Myanmar economy, which is a fundamental aspect of the “Roadmap to Democracy,” the Myanmar Government has begun intense exploitation of the Kachin region for its vast natural resources and trade routes. In light of its economic objectives for the Kachin region, the Myanmar Government has changed its approach towards the Kachin insurgency to instead favour the protection and exploitation of its investments. What complicates matters more is the involvement of China, who is pursuing its own objectives in the region. This conflict is now being shaped by the intricate and ever changing relations between various actors that struggle to control the empowering economic assets of the Kachin region; all of which has assured enduring tensions in the Kachin region.

description: The aim of this paper is to investigate an efficient strategy that allows to obtain pi-pi phase shifts and rho meson properties from QCD lattice data with high precision. For this purpose we evaluate the levels of the pi-pi system in the rho channel in finite volume using chiral unitary theory. We investigate the dependence on the pi mass and compare with other approaches which use QCD lattice calculations and effective theories. We also illustrate the errors induced by using the conventional Luscher approach instead of a more accurate one recently developed that takes into account exactly the relativistic two meson propagators. Finally we make use of this latter approach to solve the inverse problem, getting pi-pi phase shifts from "synthetic" lattice data, providing an optimal strategy and showing which accuracy is needed in these data to obtain the $ρ$ properties with a desired accuracy.

description: We prove a certain non-linear version of the Levi extension theorem for meromorphic functions. This means that the meromorphic function in question is supposed to be extendable along a sequence of complex curves, which are arbitrary, not necessarily straight lines. Moreover, these curves are not supposed to belong to any finite dimensional analytic family. The conclusion of our theorem is that nevertheless the function in question meromorphically extends along an (infinite dimensional) analytic family of complex curves and its domain of existence is a pinched domain filled in by this analytic family.

description: An experimental comparative study of nonlinear distortion effects in 26-40 GHz frequency band on telecommunication MMIC’s subject to constant wave single-tone, two-tone and NPR excitations are presented in this paper. The study is performed using a wave-guide based power measurement setup previously developed and recently fully automated to allow very accurate analyses about nonlinear behaviour of PHEMT SSPA’s. The purpose of these studies is to determine the MMIC linearity performances at 29 GHz versus bias conditions. But also to improve the PHEMT technological parameters and the circuits designs as a function of the analyses.
Probing strongly interacting atomic gases with energetic atoms

description: We investigate properties of an energetic atom propagating through strongly interacting atomic gases. The operator product expansion is used to systematically compute a quasiparticle energy and its scattering rate both in a spin-1/2 Fermi gas and in a spinless Bose gas. Reasonable agreement with recent quantum Monte Carlo simulations even at a relatively small momentum k/kF>1.5 indicates that our large-momentum expansions are valid in a wide range of momentum. We also study a differential scattering rate when a probe atom is shot into atomic gases. Because the number density and current density of the target atomic gas contribute to the forward scattering only, its contact density (measure of short-range pair correlation) gives the leading contribution to the backward scattering. Therefore, such an experiment can be used to measure the contact density and thus provides a new local probe of strongly interacting atomic gases.

description: On-wafer noise figure and insertion gain measurement set-ups have been developed over 50-110 GHz frequency range. Wafer scale noise figure and insertion gain measurements can be done in an automatic manner using PC controlled automated probe station and in-house written software. In narrow band measurements, large systematic errors may remain undiscovered. These errors are usually caused by reflections in the set-up, which are difficult to calibrate out. Wideband measurements are often the only method, which can efficiently reveal these errors. This aspect is increasingly important as frequency increases.

This formula enables one to explicitly calculate the Fourier transform of any radial function $f(r)$ in any dimension, provided one knows the Fourier transform of the one-dimensional function $t\to f(|t|)$ and the two-dimensional function $(x_1,x_2)\to f(|(x_1,x_2)|)$. We prove analogous results for radial tempered distributions.

description: For a detailed study on the semiconductor to metal transition (SMT) in ZnO thin films doped with Al in the concentration range from 0.02 to 2%, we grew these films on (0001) sapphire substrates using sequential pulsed laser deposition. It was found that the Al concentration in the films increased monotonically with the ratio of ablation durations of the Alumina and ZnO targets used during the deposition. Using X-ray photo electron spectroscopy it was found that while most of the Al atoms occupy the Zn sites in the ZnO lattice, a small fraction of the Al also gets into the grain boundaries present in the films. The observed SMT temperature decreased from ~ 270 to ~ 50 K with increase in the Al concentration from 0.02 to 0.25 %. In the Al concentration range of ~ 0.5 to 2 % these doped ZnO films showed metallic behavior at all the temperatures without undergoing any SMT. A theoretical model based on thermal activation of electrons and electron scatterings due to the grain boundaries, ionic impurities and phonons has been developed to explain the observed concentration and temperature dependent SMT.

description: We present three contributions to the understanding of QMA with multiple provers: 1) We give a tight soundness analysis of the protocol of [Blier and Tapp, ICQNM '09], yielding a soundness gap Omega(1/N^2). Our improvement is achieved without the use of an instance with a constant soundness gap (i.e., without using a PCP). 2) We give a tight soundness analysis of the protocol of [Chen and Drucker, ArXiV '10], thereby improving their result from a monolithic protocol where Theta(sqrt(N)) provers are needed in order to have any soundness gap, to a protocol with a smooth trade-off between the number of provers k and a soundness gap Omega(k^2/N), as long as k>=Omega(log N). (And, when k=Theta(sqrt(N)), we recover the original parameters of Chen and Drucker.) 3) We make progress towards an open question of [Aaronson et al., ToC '09] about what kinds of NP-complete problems are amenable to sublinear multiple-prover QMA protocols, by observing that a large class of such examples can easily be derived from results already in the PCP literature - namely, at least the languages recognized by a non-deterministic RAMs in quasilinear time.

description: Lungenkrebs steht mit 353.500 Todesfällen pro Jahr an der Spitze der Krebsstatistiken. In ca. 85% der Fälle handelt es sich um nicht-kleinzelligen Lungenkrebs (NSCLC). In dieser Arbeit wurden eingehende massenspektrometrische Analysen der Sekretome zweier verschiedener NSCLC-Zelllinien (PC9, erlotinibsensitiv und PC9ER, erlotinibresistent) durchgeführt und mittels SILAC-Ansatz quantitativ miteinander verglichen. Nicht nur bei der Krebsentstehung, sondern auch bei der Entwicklung von Resistenzen gegen Apoptose- und Nekrose-induzierende Therapien, spielen Tumor-Wirtsinteraktionen eine wichtige Rolle. Diese Interaktionen werden durch therapeutische Eingriffe modifiziert und verändern sich wesentlich, wenn Tumorzellen Resistenzen gegen spezifische Therapeutika entwickeln. Ziel der angewandten Proteomikansätze war daher nicht nur die Identifizierung unterschiedlich regulierter Proteine. Vielmehr sollten auch die Interaktionen der identifizierten Proteine charakterisiert werden.
description: Lung cancer is the most common cancer fatality in Europe (353,500 deaths/year) with non-small cell lung cancer (NSCLC) comprising 85% of all casualties. In this study, in-depth mass spectrometric analyses of NSCLC cell secretomes were conducted. For a quantitative comparison of proteins secreted by two different NSCLC cell lines (PC9, erlotinib-sensitive and PC9ER, erlotinib-resistant) a stable isotope labeling with amino acids in cell culture (SILAC) approach was applied. Tumor-host interactions play a major role in carcinogenesis, but also in resistance to apoptosis- and necrosis-inducing treatment. These interactions are modified by therapeutic interventions and change substantially when tumor cells become resistant to a therapeutic agent. The aim of the used proteomic approaches was to go beyond a mere identification of proteins that are differentially regulated between PC9 and PC9ER cells. The intention was to additionally characterize the interactions of these proteins.

description: We provide a new approach, along with extensions, to results in two important papers of Worsley, Siegmund and coworkers closely tied to the statistical analysis of fMRI (functional magnetic resonance imaging) brain data. These papers studied approximations for the exceedence probabilities of scale and rotation space random fields, the latter playing an important role in the statistical analysis of fMRI data. The techniques used there came either from the Euler characteristic heuristic or via tube formulae, and to a large extent were carefully attuned to the specific examples of the paper. This paper treats the same problem, but via calculations based on the so-called Gaussian kinematic formula. This allows for extensions of the Worsley-Siegmund results to a wide class of non-Gaussian cases. In addition, it allows one to obtain results for rotation space random fields in any dimension via reasonably straightforward Riemannian geometric calculations. Previously only the two-dimensional case could be covered, and then only via computer algebra. By adopting this more structured approach to this particular problem, a solution path for other, related problems becomes clearer.

description: Power HBT Technology offers today the best compromise for high power – high efficiency amplifiers up to Ku band. Many improvements have been published in the past to offer a better behaviour in terms of thermal heating and microwave performances. Since the reliability limiting factors have been solved, significant improvements could be proposed to get more power. In this paper, we report on the proposal of new elementary cells used in multi-finger transistors. Based on these, compact very high power amplifiers could be considered.

description: Superior DC and RF performance are obtained using InGaP/GaInAsN and InP/GaInAs double heterojunction bipolar transistors with compositionally graded base layers. By grading the base layer energy band-gap, we achieve nearly a 100% improvement in DC current gain and as much as a 15% increase in the unity gain cutoff frequency (ft) relative to baseline constant-composition base layer devices. In InGaP/GaInAsN DHBTs, DC current gains as high as 250 and cutoff frequencies of 60 GHz are demonstrated for devices with a collector thickness of 400 nm and BVceo values of 8.4 Volts. Graded-base InP/InGaAs DHBTs with an ft of 135 GHz are also demonstrated. Estimations of the ft*BVceo figure-of-merit are used to compare performance of these devices to existing technologies.
Endoplasmic reticulum membrane contact sites : roles in phospholipid synthesis and cell polarity

description: Membrane contact sites between the endoplasmic reticulum (ER) and other organelles are present in all eukaryotic cells. Their roles in calcium signaling and transport between the ER and the plasma membrane (PM) or the ER and mitochondria are quite well understood, but the molecular mechanisms underlying their roles in lipid synthesis and transport remains unknown. In order to identify the importance of organelle-ER contact sites, I used Saccharomyces cerevisiae - a model organism that has proven to be a particularly informative for studying lipid-related cellular processes. Previously, we found a role for an ER anchor protein, Scs2, being important for PM-ER contact sites. Further, SCS2 interacts genetically with ICE2, an ER gene with unknown function. In Chapter 2, I investigated a role for PM–ER contact sites in regulating phosphatidylcholine (PC) synthesis and I found that Δscs2Δice2 cells are choline auxotrophs and PM–ER contacts are required for PC synthesis. Osh2 and Osh3, the oxysterol-binding protein homologues in yeast, rescued the choline auxotrophy phenotype of Δscs2Δice2 cells but did not restore pmaER, indicating that they may function with Opi3 in PC synthesis. In search for regulators of pmaER, we identified the phosphatidic acid phosphohydrolase Pah1 that seems to be involved in establishing pmaER, independent of its enzymatic activity. Finally, we proposed that PE to PC synthesis by Opi3 happens “in trans” at PM-ER contacts. In Chapter 3, I aimed to discover novel genes involved in PE synthesis/traffic from ER to mitochondria. By doing a genome-wide screen for CHO2, we identified genetic interactions between CHO2 and Emc proteins indicating that Emc proteins are important for PE metabolism and we proposed that Emc facilitates PS transfer from the ER to mitochondria for PE synthesis. In Chapter 4, I investigated for roles of SCS2 in polarized growth. I found a physiologically important function of the ER diffusion barrier, which is to restrict diffusion of the spindle from mother to bud until M phase. Scs2 interacts directly with the spindle capture protein Num1 and it prevents Num1 from diffusing from the mother into the bud during S and G2 phases.

Model for common growth of supermassive black holes, bulges and globular star clusters: ripping off Jeans clusters

description: It is assumed that a galaxy starts as a dark halo of a few million Jeans clusters (JCs), each of which consists of nearly a trillion micro brown dwarfs, MACHOs of Earth mass. JCs in the galaxy center heat up their MACHOs by tidal forces, which makes them expand, so that coagulation and star formation occurs. Being continuously fed by matter from bypassing JCs, the central star(s) may transform into a super massive black hole. It has a fast $t^3$ growth during the first mega years, and a slow $t^{1/3}$ growth at giga years. JCs disrupted by a close encounter with this black hole can provide matter for the bulge. Those that survive can be so agitated that they form stars inside them and become globular star clusters. Thus black holes mostly arise together with galactic bulges in their own environment and are about as old as the oldest globular clusters. The age 13.2 Gyr of the star HE 1523-0901 puts forward that the Galactic halo was sufficiently assembled at that moment. The star formation rate has a maximum at black hole mass $\sim4 \ 10^7M_\odot$ and bulge mass $\sim5\,10^{10}M_\odot$. In case of merging supermassive black holes the JCs passing near the galactic center provide ideal assistance to overcome the last parsec.

description: Die vorliegende Arbeit befasst sich mit zwei neuartigen Impfstofftechnologien, welche im Rahmen der Entwicklung eines Impfstoffes gegen das Respiratorische Synzytialvirus (RSV) analysiert wurden. Im ersten Ansatz wurden nicht-humane Papilloma-Pseudovirionen als Genfähren für einen DNA-Impfstoff verwendet. In einer Impfstudie wurde ein für das RSV-F-Protein kodierendes Plasmid in MfPV11 und PcPV1 Pseudovirionen verpackt und in Mäusen appliziert. Im Vergleich zu nicht-geimpften Mäusen zeigten die immunisierten Mäuse eine signifikant verringerte Viruslast nach Challenge mit infektiösem RSV. Der zweite Ansatz beschäftigte sich mit der Analyse einer neuen Technologie zur Herstellung von Totimpfstoffen. RSV wurde mit Niedrigenergie-Elektronenbestrahlung (low-energy electron irradiation, LEEI) behandelt, und zeigte eine vollständige Inaktivierung bei 20kGy. Die Analyse der Antigenität nach Bestrahlung ergab, dass mind. 70% der viralen Proteine erhalten blieben. Das mit LEEI behandelte RSV-Material wurde in Impfstudien verwendet und führte zu einer starken Immunantwort und zum Schutz vor RSV bei Challenge mit infektiösem Virus.
description: The presented thesis deals with two novel vaccine technologies, which were analyzed in view of developing a vaccine against the respiratory syncytial virus (RSV). The first approach involved the use of non-human papilloma pseudovirions for the delivery of a DNA-vaccine. In an immunization study, mice were vaccinated in a heterologous prime-boost regimen, intramuscularly and intranasally applying a vaccine plasmid coding for the RSV F-protein packaged in MfPV11 and PcPV1 pseudovirions. In comparison to non-vaccinated mice, immunized mice showed a significantly decreased viral load upon challenge with infectious RSV. The second approach dealt with the development and analysis of a novel technology to produce killed vaccines. RSV was treated with low-energy electron irradiation (LEEI), and the required dose for complete inactivation was determined as 20kGy. Analysis of the remaining antigenicity after LEEI revealed that at least 70% of viral proteins were conserved during the process. The LEEI-treated RSV material was used in vaccination studies and yielded a strong immune response and protection against RSV upon challenge with infectious virus.

description: In the single-degenerate (SD) channel of a Type Ia supernovae (SN Ia) explosion, a main-sequence (MS) donor star survives the explosion but it is stripped of mass and shock heated. An essentially unavoidable consequence of mass loss during the explosion is that the companion must have an overextended envelope after the explosion. While this has been noted previously, it has not been strongly emphasized as an inevitable consequence. We calculate the future evolution of the companion by injecting 2-6 10^47 ergs into the stellar evolution model of a 1 Msun donor star based on the post-explosion progenitors seen in simulations. We find that, due to the Kelvin-Helmholtz collapse of the envelope, the companion must become significantly more luminous (10 - 10^3 Lsun) for a long period of time (10^3 - 10^4 years). The lack of such a luminous "leftover" star in the LMC supernova remnant SNR 0609-67.5 provides another piece of evidence against the SD scenario. We also show that none of the stars proposed as the survivors of the Tycho supernova, including Tycho G, could plausibly be the donor star. Additionally, luminous donors closer than ~10 Mpc should be observable with the Hubble Space Telescope starting ~2 years post-peak. Such systems include SN 1937C, SN 1972E, SN 1986G, and SN 2011fe. Thus, the SD channel is already ruled out for at least two nearby SNe Ia and can be easily tested for a number of additional ones. We also discuss similar implications for the companions of core-collapse SNe.

description: An integrated 12-GHz static frequency divider with a selectable division ratio (16/1, 64/1) realised in a Silicon Germanium technology dedicated for high volume production, is presented. It operates at low bias voltage (2.7-3.6V) providing balanced output signals on 50-ohm loads. The chosen architecture, the adopted design approach and used technology led to a good trade-off among maximum input frequency, input sensitivity, noise floor, power consumption, division ratioes and die size compared with the current high frequency dividers. The circuit features make itself a versatile block for high frequency PLL systems, while the circuit core can be used as a macrocell for the design of totally integrated fast PLL’s.

description: High gain shunt-series shunt-shunt wideband amplifiers with and without capacitive peaking are demonstrated by using GaInP/GaAs HBT technology. Experimental results show that power gain is 28 dB and input/output return loss is better than 12 dB from DC to 6 GHz for the wideband amplifier without emitter capacitive gain peaking. On the other hand, the wideband amplifier with emitter capacitive gain peaking has the same gain but the power gain bandwidth increases up to 8 GHz at the cost of lower input/output return loss. Power and noise performance are very similar for both types of wideband amplifiers. Both circuits have 8 dBm OP1dB and 20 dBm OIP3 at 2.4 GHz Noise figure of both designs are below 2.8 dB from 1GHz to 6GHz. Total current consumption is 67 mA at 5 V supply voltage for both wideband amplifiers.

description: A non-uniqueness problem of gauge invariant separation of quark and gluon contributions to nucleon spin is considered. We show that there is a wide number of gauge invariant spin decompositions each of them reduces to the canonical one in a special gauge. A class of physical gauge equivalent nucleon spin decompositions is selected by requirements of consistence with helicity notion described within E(2) little group representation theory and with gluon helicity Δg measured in experiment.

Process and product innovation by a multiproduct

description: We model the optimal behaviour of a multiproduct monopolist investing both
in process and in product innovation in a dynamic setting. Product innovation reduces
the degree of substitutability between any two varieties. First, we find that
R&D efforts increase in both directions as the number of varieties grows. Second,
we characterise the relative intensity of R&D activities according to the reservation
price and the interaction between the number of varieties and the degree of product
differentiation. Finally, we show the existence of complementarity within the
R&D portfolio, i.e., decreasing marginal production cost prompts for an analogous
reduction of product substitutability, and conversely.
