description: In the paper is shown that,when devices are strongly affected by low-frequency dispersion effects, simply deriving the i/v characteristics through direct integration of bias-dependent differential parameters leads to results which are only locally self-consistent and coherent with empirical data.Dynamic drain current deviations due to charge trapping and self-heating phenomena in FETs, introducing a more complex dependence on average applied voltages and power in the dynamic i/v characteristics,must be taken into account by means of accurate approaches, such as the recently proposed equivalent voltage model [2 ]. Instead,integration of the low-frequency differentialparameters in a suitably modified equivalent voltage domain is shown to be consistent with device physics. Experimental evidence is provided in the paper.

description: We use a set of four theoretical navigability indices for street maps to investigate the shape of the resulting street networks, if they are grown by optimizing these indices. The indices compare the performance of simulated navigators (having a partial information about the surroundings, like humans in many real situations) to the performance of optimally navigating individuals. We show that our simple greedy shortcut construction strategy generates the emerging structures that are different from real road network, but not inconceivable. The resulting city plans, for all navigation indices, share common qualitative properties such as the tendency for triangular blocks to appear, while the more quantitative features, such as degree distributions and clustering, are characteristically different depending on the type of metrics and routing strategies. We show that it is the type of metrics used which determines the overall shapes characterized by structural heterogeneity, but the routing schemes contribute to more subtle details of locality, which is more emphasized in case of unrestricted connections when the edge crossing is allowed.

Essays on decision-making under risk
Creators: name: Freeman, David
Publisher: name: University of British Columbia
Year: 2013

description: Chapter 2 of this thesis studies the testable content of models of expectations-based reference-dependence. The main results of this chapter characterize a model based on Kőszegi and Rabin's (2006) preferred personal equilibrium. This model is shown to be behaviourally equivalent to a version of the shortlisting model of Manzini and Mariotti (2007) in environments without risk. Environments with risk motivate novel axioms that are conceptually consistent with expectations-based reference-dependence. These axioms are shown to behaviourally characterize a restricted version of the preferred personal equilibrium model of decision-making. Additional results characterize the choice behaviour of Kőszegi and Rabin's (2006, 2007) personal equilibrium and choice-acclimating personal equilibrium concepts. In the presence of background risk and under the Reduction of Compound Lotteries axiom, non-expected utility preferences cannot capture descriptively reasonable risk aversion over small stakes without producing implausible risk aversion over large stakes (Safra and Segal 2008). Motivated by experimental evidence, Chapter 3 assumes that compound lotteries are evaluated recursively. The main results of this chapter show that non-expected utility theories generate 'as-if' narrow bracketing over small-stakes gambles despite defining utility over final wealth, and can be consistent with empirically reasonable risk aversion over both small and large stakes. Chapter 4 uses list elicitation with varying probabilities to experimentally study choices between lotteries for a population of online workers. We document that list elicitation significantly diminishes risk aversion compared to binary choice elicitation. We show that this observation is consistent with a decision maker who has non-expected utility preferences, but when list elicitation is employed, reduces the compound lottery induced by her choices and the external randomization device used to determine payment. As a result, list elicitation distorts the inferences that can be drawn about non-expected utility preferences.

description: A new procedure to learn a nonlinear model together with its derivative parameters using a composite neural network is presented.So far neural networks have never been used to extract large-signal device model accounting for distortion parameters.Applying this method to FET devices leads to nonlinear models for current- voltage functions which allow improved prediction of weak and mildly device nonlinearities in the whole bias region. The resulting models have demonstrated to be suitable for both small-signal and large-signal analyses,including intermodulation distortion prediction.

description: Harmonic Distortion (HD) of Partially and Fully Depleted Silicon-on-Insulator nMOSFETs is investigated through DC and Radio-Frequency (RF) characterization methods. Those techniques are compared and it demonstrates that in saturation, HD is dominated by the DC current-voltage characteristics and that the output conductance has to be taken into account. Accurate evaluation of HD at RF requires further measurements.

description: In this paper,a complete characterization of the linearity sweet-spot evolution in MESFET/HEMT devices is presented. A global experimental extraction of the I ds(V gs,V ds) Taylor series coefficients is used tointroduce the small-signal behavior in the linear and saturated regions. The possibility of taking advantage of these points in different applications is also discussed. For the first time, a characterization of the influence of both bias voltages on the device transition towards the large-signal regime is presented. Finally, a technique for improving the linearity-efficiency tradeoff in a class B/C power amplifier (PA) is introduced.

description: We investigate the low-energy scattering and bound states of two two-component fermionic atoms in pure two-dimensional (2D) and quasi-2D confinements with Rashba spin-orbit coupling (SOC). We find that the SOC qualitatively changes the behavior of the 2D scattering amplitude in the low-energy limit. For quasi-2D systems we obtain the analytic expression for the effective-2D scattering amplitude and the algebraic equations for the two-atom bound state energy. Based on these results, we further derive the effective 2D interaction potential between two ultracold atoms in the quasi-2D confinement with Rashba SOC. These results are crucial for the control of the 2D effective physics in quasi-2D geometry via the confinement intensity and the atomic three-dimensional scattering length.

description: We develop a π-electron effective field theory (π-EFT) wherein the two-body Hamiltonian for a π-electron system is expressed in terms of three effective parameters: the π-orbital quadrupole moment, the on-site repulsion, and a dielectric constant. As a first application of this π-EFT, we develop a model of screening in molecular junctions based on image multipole moments, and use this to investigate the reduction of the HOMO-LUMO gap of benzene. Beyond this, we also use π-EFT to calculate the differential conductance spectrum of the prototypical benzenedithiol-Au single-molecule junction and the π-electron contribution to the van der Waals interaction between benzene and a metallic electrode.

description: Walter Jakob Gehring was one of the most influential developmental biologists of the last 50 years. First as a student with Professor Ernst Hadorn in Zurich, later as a postdoc in Yale and finally as group leader in Basel, he was involved in a number of major discoveries that had a profound impact in the understanding of the genetic and molecular mechanisms of animal development, not only for the fruit fly Drosophila but for the whole animal kingdom.Throughout his career Gehring demonstrated an outstanding ability to recognize key problems and then to push experimental work on these problems with great energy. Gehring pioneered the application of molecular techniques to developmental problems, an approach that was at the root of many of his contributions. His laboratory was involved in a number of key findings: the first cloning of a Hox gene, the discovery of the homeobox, the enhancer trap method, and the remarkable conservation of features of the visual system in metazoans.He was an excellent speaker, with special ability to emphasize the relevant aspects of his work and to draw conclusions of general interest. This attracted a number of gifted students and postdocs who were key for the success of his research group.Passionately interested in science, he was also very excited about other scientific disciplines; he was an accomplished bird watcher and was also fascinated by marine life. But he also had non-scientific interests, too; he claimed to be an excellent football player and frequently commented that he had had to decide whether to be a scientist or a professional footballer. He decided on the former, but one wonders if he might have been a Swiss version of Messi or Ronaldo.

description: We present a new method to extract cosmological constraints from weak lensing (WL) peak counts, which we denote as `the hierarchical algorithm'. The idea of this method is to combine information from WL maps sequentially smoothed with a series of filters of different size, from the largest down to the smallest, thus increasing the cosmological sensitivity of the resulting peak function. We compare the cosmological constraints resulting from the peak abundance measured in this way and the abundance obtained by using a filter of fixed size, which is the standard practice in WL peak studies. For this purpose, we employ a large set of WL maps generated by ray-tracing through N-body simulations, and the Fisher matrix formalism. We find that if low-S/N peaks are included in the analysis (S/N ~ 3), the hierarchical method yields constraints significantly better than the single-sized filtering. For a large future survey such as Euclid or LSST, combined with information from a CMB experiment like Planck, the results for the hierarchical (single-sized) method are: Δn=0.0039 (0.004); ΔΩm=0.002 (0.0045); Δσ8=0.003 (0.006); Δw=0.019 (0.0525). This forecast is conservative, as we assume no knowledge of the redshifts of the lenses, and consider a single broad bin for the redshifts of the sources. If only peaks with S/N >= 6 are considered, then there is little difference between the results of the two methods. We also examine the statistical properties of the hierarchical peak function: Its covariance matrix has off-diagonal terms for bins with S/N <= 6 and aperture mass of M < 3 x 1e+14 Ms/h, the higher bins being largely uncorrelated and therefore well described by a Poisson distribution.

description: A new modified Gummel-Poon (MGP) based model has been developed and tested on heterojunction bipolar transistors (HBTs).This paper focuses on the comparison of the new MGP and the VBIC models under DC and small-signal operations.The DC parameters of the two models are extracted from Gummel forward and reverse measurements at various junction temperatures and Ic-Vce measurements.The small-signal intrinsic elements are extracted from multi-bias s- parameter measurements.DC comparisons between the twomodel predictions and measurements reveal that the newMGP model surpasses the VBIC DC performances.The s-parameter comparisons of simulated and measurements at various bias points,from 1Ghz to 30Ghz,show that the two models are equivalent.

description: Endonuklease G (EndoG) ist eine DNA/RNA‐unspezifische Endonuklease, die während der Apoptose aus dem Intermembranraum der Mitochondrien in das Zytoplasma entlassen wird und vermutlich am Abbau nukleärer DNA beteiligt ist. In dieser Studie wurden die EndoG und ihr spezifischer Inhibitor (EndoGI) aus Drosophila melanogaster untersucht, wobei das Augenmerk auf der Untersuchung des EndoGEndoGI‐Komplexes lag. Die intrazelluläre Lokalisation und Substratspezifität der Drosophila‐EndoG ist vergleichbar mit zuvor beschriebenen Enzymen der gleichen Nukleasefamilie. Bei EndoGI handelt es sich um ein vorherrschend nukleäres Protein, welches aus zwei tandemartig angeordneten, homologen Domänen besteht. EndoGI ist in der Lage die katalytische Aktivität von EndoG unmittelbar und sofort zu inhibieren, wobei vermutlich einfache Assoziation für die Bindung von EndoGI durch EndoG verantwortlich ist. Mittels analytischer Ultrazentrifugation konnte gezeigt werden, dass EndoG als Homodimer vorliegt und mit dem monomeren EndoGI einen 2:1‐Komplex bildet. In weiteren Titrationen wurde nachgewiesen, dass beide homologen EndoGI‐Domänen in der Lage sind EndoG alleine zu inhibieren. Mit einem Kd‐Wert im subpikomolaren Bereich und einer berechneten Halbwertszeit von 3 Tagen handelt es sich um einen sehr stabilen Poteinkomplex.

description: Recently, Chau [Quant. Inform. & Comp. 11, 721 (2011)] found a family of metrics and pseudo-metrics on $n$-dimensional unitary operators that can be interpreted as the minimum resources (given by certain tight quantum speed limit bounds) needed to transform one unitary operator to another. This result is closely related to the weighted $\ell^1$-norm on ${\mathbb R}^n$. Here we generalize this finding by showing that every weighted $\ell^p$-norm on ${\mathbb R}^n$ with $1\le p \le \limitingp$ induces a metric and a pseudo-metric on $n$-dimensional unitary operators with quantum information-theoretic meanings related to certain tight quantum speed limit bounds. Besides, we investigate how far the correspondence between the existence of metrics and pseudo-metrics of this type and the quantum speed limits can go.

description: It is proved that for memoryless vector channels, maximizing the mutual information over all source distributions with a certain average power or over the larger set of source distributions with upperbounded average power yields the same channel capacity in both cases. Hence, the channel capacity cannot decrease with increasing average transmitted power, not even for channels with severe nonlinear distortion.

The effects of resettlement on community recovery : an analysis of post-tsunami Aceh, Indonesia
Creators: name: Panjwani, Dilnoor
Publisher: name: University of British Columbia
Year: 2014

description: In a context of constrained time, resources and geographical space, populations displaced by natural disaster often face diverse and/or ad hoc resettlement schemes. The purpose of this dissertation is to understand factors that can influence successful resettlement several years after a natural disaster so that it may better inform the management and planning of recovery processes. As such, this research asks: ‘How do resettlement patterns influence long-term holistic community disaster recovery?’ To address this question, this study explores recovery across five communities affected by the 2004 Indian Ocean Tsunami in Aceh, Indonesia. Using a mixed methods comparative case study design, villages in Banda Aceh and Aceh Besar that represent differences in resettlement process and pattern were targeted. Findings are based on fieldwork across these communities – Bitai, Gampong Baro, Lampulo, Neheun Compound and Panteriek Compound – six years after the disaster. Data collection included key informant interviews (i.e., village chief, elders, etc.), key expert interviews (i.e., members of government, NGOs, and academia), focus group discussions (i.e., villagers), direct observations, and secondary data. In the absence of a generally accepted method to measure community disaster recovery, a survey tool was implemented to assess holistic wellbeing outcomes. This tool is developed by operationalizing a capabilities-based approach through a series of steps that lead to a multi- dimensional recovery index. Results show that differences in overall recovery across the villages are not explained by either resettlement process (participation versus non participation) or pattern (resettlement in previous location versus in new location). Further qualitative data analysis displays that resettlement success in the five cases is influenced by (1) location, which shapes livelihood, connectivity and safety, and (2) built environment, which shapes sociability, identity and belonging. Comparisons across cases highlight that these influences impact recovery through a number of mechanisms of importance, such as access to governance structures, availability of gathering places, and social norms and behaviours. The analysis also describes how mechanisms are mediated by leadership, proximity and community composition. The findings support a broader understanding of post-disaster processes, including an emphasis on intangible dimensions and a need to approach resettlement using a lens of ‘place’.

description: Die Arbeit stellt eine erste theoretische Analyse der Wirksamkeit und möglicher Probleme einer marktbasierten Eigenkapitalregulierung in Form einer regulatorischen Nachschusspflicht dar. Hart und Zingales (2011) schlagen vor, dass Finanzinstitute zusätzliches Eigenkapital aufnehmen sollen, wenn die Marktbewertung ihrer Ausfallwahrscheinlichkeit, gemessen am Preis für Kreditausfallversicherungen,eine kritische Grenze überschreitet. Andernfalls verpflichtet sich der Regulierer zu einer ex ante definierten Intervention. In der Arbeit wird untersucht, welche Auswirkung dieser Regulierungsvorschlag auf den Trade-off zwischen Finanzstabilität und Kreditvergabeeffizienz auch im Vergleich mit zentralen Elementen desBasel III Akkords hat. Ferner wird analysiert, inwiefern die Wirksamkeit der Nachschusspflicht von Informationsasymmetrien über die Qualität der Aktiva abhängt. Es wird argumentiert, dass es der zunehmenden Komplexität des Basler Regulierungsrahmens nicht zwingend bedarf.
description: This thesis constitutes a first theoretical analysis of the effects and potential problems of a market based capital requirement in the form of a regulatory margin call. Hart and Zingales (2011) propose that financial institutions will have to issue additional equity if the market evaluation of their probability of default measured based on the price of credit default swaps reaches a certain threshold. Otherwise the regulator is obliged to a predefined intervention. On the one hand I analyze the impact of this regulation on the trade-off between financial stability and efficient bank lending also in comparison with central instruments of the Basel III Accord. On the other hand, I study in how far the effectiveness of the margin call is hampered in the presence of asymmetric information with respect to the quality of bank assets. I argue that the currently observed increasing complexity of the Basel Accord is not needed.
Breakdown of the large-scale wind in Γ=1/2 rotating Rayleigh-Bénard flow

description: Experiments and simulations of rotating Rayleigh-Bénard convection in cylindrical samples have revealed an increase in heat transport with increasing rotation rate. This heat transport enhancement is intimately related to a transition in the turbulent flow structure from a regime dominated by a large-scale circulation (LSC), consisting of a single convection roll, at no or weak rotation to a regime dominated by vertically-aligned vortices at strong rotation. For a sample with an aspect ratio Γ= D/L = 1 (D is the sample diameter and L its height) the transition between the two regimes is indicated by a strong decrease in the LSC strength. In contrast, for Γ= 1/2 Weiss and Ahlers [J. Fluid Mech. {\bf{688}}, 461 (2011)] revealed the presence of a LSC-like sidewall temperature signature beyond the critical rotation rate. They suggested that this might be due to the formation of a two-vortex state, in which one vortex extends vertically from the bottom into the sample interior and brings up warm fluid, while another vortex brings down cold fluid from the top; this flow field would yield a sidewall temperature signature similar to that of the LSC. Here we show by direct numerical simulations for Γ= 1/2 and parameters that allow direct comparison with experiment that the spatial organization of the vertically-aligned vortical structures in the convection cell do indeed yield (for the time average) a sinusoidal variation of the temperature near the sidewall, as found in the experiment. This is also the essential and non-trivial difference with the Γ=1 sample, where the vertically-aligned vortices are distributed randomly.

description: We present a theory for manipulation of d-wave interaction of cold atoms with two lasers strongly driving two photoassociative transitions. The theory predicts the occurrence of a coherence between two excited ro-vibrational bound states due to the photoassociative dipole-couplings of ground-state d-wave scattering state to the bound states. We show that this excited-state coherence significantly influences atom-atom interaction. In particular, this leads to the enhancement of d-wave elastic scattering and to the suppression of inelastic scattering. In the presence of an s-wave magnetic Feshbach resonance, the two lasers can couple the s-wave resonance with the d-wave scattering state leading to the further enhancement in d-wave scattering at relatively low energy. Our numerical calculations based on realistic parameters show that d-wave manipulation would be most effective in case of atoms having excited diatomic states with narrow natural linewidth. We estimate that at 100 $μ$K the inelastic scattering rate in Yb can be reduced to 20 s$^{-1}$ while the elastic scattering rate can be two orders of magnitude larger.

description: This paper presents a new methodology which provides easy layout data compatibility between microwave CADs (mw-CADs) or between an mw-CAD and a mask design CAD. With storing all parameters for representing parameterized cell (p-cell) into pattern- or attribute-text areas on GDS-II format, the methodol-ogy enables easy data transfer including p-cells between commercial mw-CADs, and promises time-saving de-sign cycles for MMICs.
The targum (1869:May)
Creators: name: No Name Supplied
Publisher: name: Targum Association
Year: 1869

description: Some University historians indicate that the Targum was first published as an annual in 1867, but of this we have no extant evidence. In January 1869, the Targum as we now know it, made its appearance as a monthly paper that concerned itself with student “literary contributions” and college news as well as serving as a vehicle for bringing news to alumni and the general public. The newspaper, which originally was for sale, varied in frequency over the years as did its title (The Targum, Rutgers Targum, Rutgers Daily Targum, and Daily Targum). The newspaper has continuously been published since 1869 with the exception of 19 months during the second world war, between February 1944 and October 1945. The Targum was published by the students of Rutgers College, and later Rutgers University—New Brunswick represented through the years as the Targum Association, Rutgers Targum Association, and Rutgers College Targum. As a student organization, the Targum operated under the oversight of the dean of students and student government but in October 1980, the Targum became an independent college paper.

Hierarchical Object Parsing from Structured Noisy Point Clouds
Creators: name: Barbu, Adrian

description: Object parsing and segmentation from point clouds are challenging tasks because the relevant data is available only as thin structures along object boundaries or other features, and is corrupted by large amounts of noise. To handle this kind of data, flexible shape models are desired that can accurately follow the object boundaries. Popular models such as Active Shape and Active Appearance models lack the necessary flexibility for this task, while recent approaches such as the Recursive Compositional Models make model simplifications in order to obtain computational guarantees. This paper investigates a hierarchical Bayesian model of shape and appearance in a generative setting. The input data is explained by an object parsing layer, which is a deformation of a hidden PCA shape model with Gaussian prior. The paper also introduces a novel efficient inference algorithm that uses informed data-driven proposals to initialize local searches for the hidden variables. Applied to the problem of object parsing from structured point clouds such as edge detection images, the proposed approach obtains state of the art parsing errors on two standard datasets without using any intensity information.

Bifurcation Synthesis by means of Harmonic Balance and Conversion Matrix
Creators: name: Leuzzi, Giorgio
name: Di Paolo, F.
Publisher: name: Alma Mater Studiorum - Università di Bologna
Year: 2003
Subjects: ING-INF/01 Elettronica

description: In this paper a new bifurcation synthesis procedure is described. Its foundations are built on an extension of the Conversion Matrix concept, applied to the nonlinear sub network of the circuit simulated through Harmonic Balance. The Cross-frequency Stability Curves (CSC) are defined, which are the nonlinear equivalent of the Stability Circles valid for linear networks. The CSC gives us regions of reflection coefficient values for the loads that yield potential eriod doubling in the circuit. The proposed synthesis method can be used within any simulation  program based on the Harmonic Balance algorithm, allowing the designer the possibility to check the nonlinear stability of any simulated circuit, or to design intentionally unstable circuits. Results of the CSC method are given for a GaAs FET circuit synthesized to operate as a divider-by-two.

description: SAMP is a messaging protocol that enables astronomy software tools to interoperate and communicate. IVOA members have recognised that building a monolithic tool that attempts to fulfil all the requirements of all users is impractical, and it is a better use of our limited resources to enable individual tools to work together better. One element of this is defining common file formats for the exchange of data between different applications. Another important component is a messaging system that enables the applications to share data and take advantage of each other's functionality. SAMP builds on the success of a prior messaging protocol, PLASTIC, which has been in use since 2006 in over a dozen astronomy applications and has proven popular with users and developers. It is also intended to form a framework for more general messaging requirements.

description: In astrophysics and meteorology there exist numerous situations where flows exhibit small velocities compared to the sound speed. To overcome the stringent timestep restrictions posed by the predominantly used explicit methods for integration in time the Euler (or Navier-Stokes) equations are usually replaced by modified versions. In astrophysics this is nearly exclusively the anelastic approximation. Kwatra et al. have proposed a method with favourable time-step properties integrating the original equations (and thus allowing, for example, also the treatment of shocks). We describe the extension of the method to the Navier-Stokes and two-component equations. - However, when applying the extended method to problems in convection and double diffusive convection (semiconvection) we ran into numerical difficulties. We describe our procedure for stabilizing the method. We also investigate the behaviour of Kwatra et al.'s method for very low Mach numbers (down to Ma = 0.001) and point out its very favourable properties in this realm for situations where the explicit counterpart of this method returns absolutely unusable results. Furthermore, we show that the method strongly scales over 3 orders of magnitude of processor cores and is limited only by the specific network structure of the high performance computer we use.

description: An unsolved problem in relativistic quantum information research is how to model efficient, directional quantum communication between localised parties in a fully quantum field theoretical framework. We propose a tractable approach to this problem based on solving the Heisenberg evolution of localized field observables. We illustrate our approach by analysing, and obtaining approximate analytical solutions to, the problem of communicating coherent states between an inertial sender, Alice and an accelerated receiver, Rob. We use these results to determine the efficiency with which continuous variable quantum key distribution could be carried out over such a communication channel.

Cooperation and colony size as drivers of differential resource use among sympatric social predators
Creators: name: Harwood, Gyan
Publisher: name: University of British Columbia
Year: 2013

description: Dietary differentiation is an integral component of species coexistence, and among solitary predators, body size differences allow each species to capture a different range of prey sizes. Social predators, however, are able to capture much larger prey than an individual, so prey size use is additionally influenced by group size and behavioural dynamics. To investigate this, we looked at cooperative hunting among three species of sympatric group-living spiders in Brazil that construct colonies of different sizes and are known to capture different sizes of prey. We performed feeding experiments to determine whether differential prey size use is produced by differences in group behaviour and group size. For each species we measured the level of cooperation and examined how colony size influenced group behaviour. We found that two of the species which live in equally large, multi-generational colonies displayed differences in their cooperation and prey size selectivity that are consistent with differences in prey size use previously observed: the species which captures larger prey in natural hunting scenarios showed higher levels of cooperation among hunters during the trials, and had more individuals participate when presented with large prey. The third species, which lives in smaller, temporary colonies, displayed the highest levels of cooperation and prey capture success, despite capturing the smallest prey on average in natural hunting scenarios. This disparity likely reflects the natural size distribution of colonies of this species, which is greatly dominated by solitary individuals that cannot capture the largest prey on their own. This study shows that behavioural differences among group-living predators, in addition to colony size differences, may be responsible for differential prey size use.
