description: In this paper we propose to use Lie sphere-geometry as a new tool to systematically construct time-symmetric initial data for a wide variety of generalised black-hole configurations in lattice cosmology. These configurations are iteratively constructed analytically and may have any degree of geometric irregularity. We show that for negligible amounts of dust these solutions are similar (in a sense made precise) to the swiss-cheese models at the moment of maximal expansion. As Lie sphere-geometry has so far not received much attention in cosmology, we will devote a large part of this paper to explain its geometric background in a language familiar to general relativists.

(Non-)Abelian Kramers-Wannier duality and topological field theory
Creators: name: Severa, Pavol
Publisher: name: arXiv
Year: 2002
Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: We study a connection between duality and topological field theories. First, 2d Kramers-Wannier duality is formulated as a simple 3d topological claim (more or less Poincare duality), and a similar formulation is given for higher-dimensional cases. In this form they lead to simple TFTs with boundary coloured in two colours. The statistical models live on the boundary of these TFTs, as in the CS/WZW or AdS/CFT correspondence. Classical models (Poisson-Lie T-duality) suggest a non-abelian generalization in the 2dcase, with abelian groups replaced by quantum groups. Amazingly, the TFT formulation solves the problem without computation: quantum groups appear in pictures, independently of the classical motivation. Connection with Chern-Simons theory appears at the symplectic level, and also in the pictures of the Drinfeld double: Reshetikhin-Turaev invariants of links in 3-manifolds, computed from the double, are included in these TFTs. All this suggests nice phenomena in higher dimensions.

description: The first part of the dissertation presents Michal's biography according to 1-2 Sam. The literary quality of the Hebrew text is discussed as well as the questions which it raises, its lacunae and how these are filled in other ancient Jewish texts (1 Chr, LXX, Josephus, rabbinical literature) and in German translations of the last two centuries. The second part elucidates the attractivity of the Michal-figure as a protagonist in the work of German-Jewish poets from the past century to the present, the significance of the choice of this protagonist for their biography and work, their filling of the gaps of the Hebrew text and the contribution of their literary creations to the broadening of the scholarly horizon and of academic interpretations. Due to the focus in the second part of the dissertation, Jewish biblical scholarly approaches are used in dealing with the Hebrew text. Both, the German-Jewish literature and the Hebrew text, are approached from the point of view of literary studies.

description: This paper presents a literature review on recent applications and design aspects of the intelligent reflecting surface (IRS) in the future wireless networks. Conventionally, the network optimization has been limited to transmission control at two endpoints, i.e., end users and network controller. The fading wireless channel is uncontrollable and becomes one of the main limiting factors for performance improvement. The IRS is composed of a large array of scattering elements, which can be individually configured to generate additional phase shifts to the signal reflections. Hence, it can actively control the signal propagation properties in favor of signal reception, and thus realize the notion of a smart radio environment. As such, the IRS's phase control, combined with the conventional transmission control, can potentially bring performance gain compared to wireless networks without IRS. In this survey, we first introduce basic concepts of the IRS and the realizations of its reconfigurability. Then, we focus on applications of the IRS in wireless communications. We overview different performance metrics and analytical approaches to characterize the performance improvement of IRS-assisted wireless networks. To exploit the performance gain, we discuss the joint optimization of the IRS's phase control and the transceivers' transmission control in different network design problems, e.g.,~rate maximization and power minimization problems. Furthermore, we extend the discussion of IRS-assisted wireless networks to some emerging use cases. Finally, we highlight important practical challenges and future research directions for realizing IRS-assisted wireless networks in beyond 5G communications.

description: We analyze the response of a complex quantum-mechanical system (e. g., a quantum dot) to a time-dependent perturbation. Assuming the dot energy spectrum and the perturbation to be described by the Gaussian Orthogonal Ensemble of random matrices we find the quantum corrections to the energy absorption rate as a function of dephasing time. If the perturbation is a sum of d harmonics with incommensurate frequencies, the quantum corrections behave similarly to those of conductivity for the d-dimensional Anderson model of the orthogonal symmetry class. For periodic perturbations, the leading quantum corrections are generically absent as in the systems of the unitary symmetry class. Exceptions are the harmonic perturbation and all other periodic perturbations that obey the generalized time-reversal condition (with an arbitrary time shift). Such cases fall into the quasi-1d orthogonal universality class.

description: In high dimensional quantum communication networks, quantum frequency convertor (QFC) is indispensable as an interface in the frequency domain. For example, many QFCs have been built to link atomic memories and fiber channels. However, almost all of QFCs work in a two-dimensional space. It is still a pivotal challenge to construct a high-quality QFC for some complex quantum states, e.g., a high dimensional single-photon state that refers to a qudit. Here, we firstly propose a high-dimensional QFC for an orbital angular momentum qudit via sum frequency conversion with a flat top beam pump. As a proof-of-principle demonstration, we realize quantum frequency conversions for a qudit from infrared to visible range. Based on the qudit quantum state tomography, the fidelities of converted state are 98.29(95.02)\%, 97.42(91.74)\%, and 86.75(67.04)\% for a qudit without (with) dark counts in 2,3, and 5 dimensions, respectively. The demonstration is very promising for constructing a high capacity quantum communication network.

description: After inflation occurs, a weakly coupled scalar field will in general not be in thermal equilibrium but have a distribution of values determined by the inflationary Hubble parameter. If such a field subsequently undergoes discrete symmetry breaking, then the different degenerate vacua may not be equally populated so the domain walls which form will be `biased' and the wall network will subsequently collapse. Thus the cosmological domain wall problem may be solved for sufficiently weakly coupled fields in a post-inflationary universe. We quantify the criteria for determining whether this does happen, using a Higgs-like potential with a spontaneously broken $Z_2$ symmetry.

description: With increasing popularity of digital cameras, the field of Computa- tional Photography emerges as one of the most demanding areas of research. In this thesis we study and develop novel priors and op- timization techniques to solve inverse problems, including disparity estimation and image restoration. The disparity map estimation method proposed in this thesis incor- porates multiple frames of a stereo video sequence to ensure temporal coherency. To enforce smoothness, we use spatio-temporal connec- tions between the pixels of the disparity map to constrain our solution. Apart from smoothness, we enforce a consistency constraint for the disparity assignments by using connections between the left and right views. These constraints are then formulated in a graphical model, which we solve using mean-field approximation. We use a filter-based mean-field optimization that perform efficiently by updating the dis- parity variables in parallel. The parallel updates scheme, however, is not guaranteed to converge to a stationary point. To compare and demonstrate the effectiveness of our approach, we developed a new optimization technique that uses sequential updates, which runs ef- ficiently and guarantees convergence. Our empirical results indicate that with proper initialization, we can employ the parallel update scheme and efficiently optimize our disparity maps without loss of quality. Our method ranks amongst the state of the art in common benchmarks, and significantly reduces the temporal flickering artifacts in the disparity maps. In the second part of this thesis, we address several image restora- tion problems such as image deblurring, demosaicing and super- resolution. We propose to use denoising autoencoders to learn an approximation of the true natural image distribution. We parametrize our denoisers using deep neural networks and show that they learn the gradient of the smoothed density of natural images. Based on this analysis, we propose a restoration technique that moves the so- lution towards the local extrema of this distribution by minimizing the difference between the input and output of our denoiser. Weii demonstrate the effectiveness of our approach using a single trained neural network in several restoration tasks such as deblurring and super-resolution. In a more general framework, we define a new Bayes formulation for the restoration problem, which leads to a more efficient and robust estimator. The proposed framework achieves state of the art performance in various restoration tasks such as deblurring and demosaicing, and also for more challenging tasks such as noise- and kernel-blind image deblurring.

description: In the standard cosmological model, dark matter drives the structure formation and constructs potential wells within which galaxies may form. The baryon fraction in dark halos can reach the universal value (15.7%) in massive clusters and decreases rapidly as the mass of the system decreases. The formation of dwarf galaxies is sensitive both to baryonic processes and the properties of dark matter owing to the shallow potential wells in which they form. In dwarf galaxies in the Local Group, dark matter dominates the mass content even within their optical-light half-radii (r_e ~ 1 kpc). However, recently it has been argued that not all dwarf galaxies are dominated by dark matter. Here we report 19 dwarf galaxies that could consist mainly of baryons up to radii well beyond r_e, at which point they are expected to be dominated by dark matter. Of these, 14 are isolated dwarf galaxies, free from the influence of nearby bright galaxies and high dense environments. This result provides observational evidence that could challenge the formation theory of low-mass galaxies within the framework of standard cosmology. Further observations, in particular deep imaging and spatially-resolved kinematics, are needed to constrain the baryon fraction better in such galaxies.

Applications of Resource-Constrained Project Scheduling in Service Operations Management
Creators: name: Zimmermann, Adrian
Publisher: name: Universität Bern

Subjects: 650 Management & public relations

description: Service companies employ expensive personnel to provide services for their customers. Each service may involve a large number of individual activities that must be executed by the company's personnel. Furthermore, the customers often pay for the services provided once all these activities have been completed. Hence, in general, managers plan the service operations of their companies such that the time required to complete each service is minimized, i.e., the available personnel is utilized in the most efficient way. In this dissertation, we consider two complex planning problems that arise in service operations management: the short-term planning of assessment centers and the scheduling of projects with so-called work-content constraints. Both planning problems consist of a prescribed number of activities that must be executed by the available personnel such that the duration of the service, i.e., the duration of the assessment or the project, is minimized. We interpret these two planning problems as specific applications of the well-known resource-constrained project scheduling problem, and we devise novel solution approaches for the planning problems that are based on concepts and methods from the corresponding project-scheduling literature. For the short-term planning of assessment centers, we devise a multi-pass list-scheduling heuristic and five alternative mixed-integer linear programming formulations. For the scheduling of projects with work-content constraints, we develop a mixed-integer programming-based heuristic. Our computational results indicate that the proposed approaches obtain optimal or near-optimal solutions for the two respective planning problems in a short amount of computation time.

description: Integrated nonlinear photonic circuits received rapid development in recent years, providing all-optical functionalities enabled by cavity-enhanced photon-photon interaction for classical and quantum applications. A high-efficiency fiber-to-chip interface is key to the use of these integrated photonic circuits for quantum information tasks, as photon loss is a major source that weakens quantum protocols. Here, overcoming material and fabrication limitation of thin-film aluminum nitride by adopting a stepwise waveguiding scheme, we demonstrate low-loss adiabatic fiber-optic couplers in aluminum nitride films with a substantial thickness (600 nm) for optimized nonlinear photon interaction. For telecom (1550 nm) and near-visible (780 nm) transverse magnetic-polarized light, the measured insertion loss of the fiber-optic coupler is -0.97 dB and -2.6 dB, respectively. Our results will facilitate the use of aluminum nitride integrated photonic circuits as efficient quantum resources for generation of entangled photons and squeezed light on microchips.

description: The goal of this work was to increase the performance and to calibrate one of the ROSINA sensors, the Reflectron-type Time-Of-Flight mass spectrometer, currently flying aboard the ESA Rosetta spacecraft. Different optimization techniques were applied to both the lab and space models, and a static calibration was performed using different gas species expected to be detected in the vicinity of comet 67P/Churyumov-Gerasimenko. The database thus created was successfully applied to space data, giving consistent results with the other ROSINA sensors.

description: Agritourism is an important alternative farm enterprise strategy in the U.S., especially for farms operating under urban influence. This paper develops a logit model to identify the characteristics of farms engaged in agritourism using 2007 Census of Agriculture respondent-level records. New Jersey, which ranks first nationally in the proportion of farm income derived from agritourism, provides the geographic context. We find that fruit/vegetable farms, rural residential/retirement farms, and intermediate-scale farms are more likely to offer agritourism. We also find that the likelihood of engaging in agritourism is significantly higher for farms employing organic production techniques and farm conservation practices.

description: We investigate the pp-wave limit of the AdS_3\times S^3\times K3 compactification of Type IIB string theory from the point of view of the dual Sym_N(K3) CFT. It is proposed that a fundamental string in this pp-wave geometry is dual to the c=6 effective string of the Sym_N(K3) CFT, with the string bits of the latter being composed of twist operators. The massive fundamental string oscillators correspond to certain twisted Virasoro generators in the effective string. It is shown that both the ground states and the genus expansion parameter (at least in the orbifold limit of the CFT) coincide. Surprisingly the latter scales like J^2/N rather than the J^4/N^2 which might have been expected. We demonstrate a leading-order agreement between the pp-wave and CFT particle spectra. For a degenerate special case (one NS 5-brane) an intriguing complete agreement is found.

We show the hybridization of moiré interlayer exciton with photons in a planar 2D cavity leads to two types of moiré polaritons that exhibit distinct forms of topological transport phenomena including the spin/valley Hall and polarization Hall effects, which feature remarkable electrical tunability through the control of exciton-cavity detuning by the interlayer bias.

description: Increasing concerns about a healthy diet, food safety and support for the local economy provide new opportunities for farmers to increase their farm income by selling their farm products locally. The major challenge for the farmers is to predict consumer preferences correctly and provide goods to the market accordingly. By analyzing a consumer survey conducted in the Midwest region of the US, the current study analyzes the consumer preferences for domestic and imported artisan cheese. The results of the econometric analysis show that consumer preferences vary between domestic and imported artisan cheese. The results also show that consumer preferences vary with location. Hence, producers of local artisan cheese might need to adopt different marketing and production strategies to match the local consumer demand.

description: Veränderung ist eine Konstante im heutigen unternehmerischen Wettbewerb - sei es eine Veränderung der Kundenbedürfnisse, eine Veränderung im Sinne des technologischen Fortschritts oder eine Veränderung des Wettbewerberumfelds. Dadurch werden Unternehmen kontinuierlich vor die Herausforderung gestellt, ihre unternehmerische Wertschöpfung regelmässig an die jeweilige Veränderung anzupassen. Nur wenn diese Anpassung gelingt, können Unternehmen einen nachhaltigen Unternehmenserfolg erzielen. Für die Anpassung der unternehmerischen Wertschöpfung ist ein abgestimmtes Set an Fähigkeiten erforderlich. So müssen Unternehmen zunächst in der Lage sein, Veränderung in den verschiedenen Dimensionen – Kunden, Technologie, Wettbewerber – zu erkennen. Anschliessend müssen Unternehmen aus der erkannten Veränderung angemessene Handlungskonzepte ableiten können, anhand derer die unternehmerische Wertschöpfung angepasst werden kann. Schliesslich müssen Unternehmen über Fähigkeiten verfügen, die Handlungskonzepte realisieren zu können. Diese drei Arten von Fähigkeiten bilden das Grundgerüst des Konzepts dynamischer Fähigkeiten („Dynamic Capabilities“) nach David J. Teece. Mit dem Konzept der Rekonfiguration unternehmerischer Wertschöpfung anhand dynamischer Fähigkeiten hat Teece eine Möglichkeit geschaffen, nachhaltigen Unternehmenserfolg in veränderlichen Märkten zu erklären. Durch das Konzept wird allerdings noch nicht die Frage beantwortet, wie sich die Rekonfiguration konkret manifestiert und zum Unternehmenserfolg beiträgt. In der vorliegenden Untersuchung wird eine Antwort auf diese Frage entwickelt. Es wird die These aufgestellt und überprüft, nach der die dynamischen Fähigkeiten positiv auf die Unternehmensinnovativität wirken. Als Resultat der verbesserten Unternehmensinnovativität sollten Unternehmen dann einen nachhaltigen Erfolg erzielen können. Dazu werden im ersten Teil der Untersuchung (Kapitel 1-4) die Forschungsfragen aus der Literatur abgeleitet, und es werden die zu überprüfenden Hypothesen entwickelt. Im zweiten Teil (Kapitel 5-9) werden zunächst die Ergebnisse einer qualitativen Vorstudie vorgestellt. Danach folgen die Erläuterungen der Operationalisierungen sowie der Untersuchungsmethodik. Im Anschluss werden die Ergebnisse der quantitativen Untersuchung präsentiert und erläutert. Abschliessend werden die Ergebnisse kritisch diskutiert und Schlussfolgerungen für die Forschung sowie die unternehmerische Praxis abgeleitet.

description: Sometimes a vegetable is just a vegetable, but how and where it is grown and sold can imbue a lowly potato with status: organic, local, Fairtrade, Peruvian! This paper examines the symbolic value of Community Supported Agriculture (CSA) as a vegetable delivery system using a focus group study. We find that for both current and former members, CSA has both symbolic and private meaning and confers status to vegetables, but has little influence on the perceived status of agriculture. However, only continuing CSA members demonstrate learned cues, perceptions of appraisal, improved role performance, and confer status to the CSA farmer.

description: Most of the empirical work addressing imperfect competition in international agricultural trade has focused on grains and meats. The present study is an attempt to help fill the gap by assessing market competitiveness in the US fresh papaya market, which can be characterized as oligopolistic whereby Mexico, Belize, and Brazil are the main suppliers. In order to assess the intensity of competition among fresh papaya exporters in the US market, an inverse residual demand model is specified and estimated. The findings suggest that Mexico, Belize, and Brazil are completely constrained in exercising market power in the US fresh papaya market.

description: Tuning the frequency of a resonant element is of vital importance in both the macroscopic world, such as when tuning a musical instrument, as well as at the nanoscale. In particular, precisely controlling the resonance frequency of isolated nanoelectromechanical resonators (NEMS) has enabled innovations such as tunable mechanical filtering and mixing as well as commercial technologies such as robust timing oscillators. Much like their electronic device counterparts, the potential of NEMS grows when they are built up into large-scale arrays. Such arrays have enabled neutral-particle mass spectroscopy and have been proposed for ultralow-power alternatives to traditional analog electronics as well as nanomechanical information technologies like memory, logic, and computing. A fundamental challenge to these applications is to precisely tune the vibrational frequency and coupling of all resonators in the array, since traditional tuning methods, like patterned electrostatic gating or dielectric tuning, become intractable when devices are densely packed. Here, we demonstrate a persistent, rewritable, scalable, and high-speed frequency tuning method for graphene-based NEMS. Our method uses a focused laser and two shared electrical contacts to photodope individual resonators by simultaneously applying optical and electrostatic fields. After the fields are removed, the trapped charge created by this process persists and applies a local electrostatic tension to the resonators, tuning their frequencies. By providing a facile means to locally address the strain of a NEMS resonator, this approach lays the groundwork for fully programmable large-scale NEMS lattices and networks.

description: We investigate the sensitivity of a disordered system with diffractive scatterers to a weak external perturbation. Specifically, we calculate the fidelity M(t) (also called the Loschmidt echo) characterizing a return probability after a propagation for a time $t$ followed by a backward propagation governed by a slightly perturbed Hamiltonian. For short-range scatterers we perform a diagrammatic calculation showing that the fidelity decays first exponentially according to the golden rule, and then follows a power law governed by the diffusive dynamics. For long-range disorder (when the diffractive scattering is of small-angle character) an intermediate regime emerges where the diagrammatics is not applicable. Using the path integral technique, we derive a kinetic equation and show that M(t) decays exponentially with a rate governed by the classical Lyapunov exponent.

description: Ziel vorliegender Arbeit ist, das Disziplinarrecht und dessen tendenzielle Abschaffung aufzu-arbeiten. Dazu wird im ersten Teil der Arbeit geprüft, ob die Grundlagen des Disziplinarrechts - die disziplinarrechtliche Verantwortlichkeit, das besondere Rechtsverhältnis sowie die Treuepflicht - nach wie vor bedeutsam sind. Weiter wird das Disziplinarwesen als rechtliches Institut begründet und die Restbestimmungen des Disziplinarrechts werden veranschaulicht. Gegenstand der Aufzeichnung des Ist-Zustandes ist weiter, den Inhalt des Disziplinarrechts aufzuzeigen und dieses von der Administrativuntersuchung, dem Strafverfahren, dem perso-nalrechtlichen Verfahren und der Umsetzung ethischer Standards abzugrenzen, um festzu-stellen, ob eines dieser Verfahren in der modernen Verwaltung dazu geeignet ist, die Funkti-on des Disziplinarverfahrens zu übernehmen. Im zweiten Teil der Arbeit werden die gewonnenen Erkenntnis verarbeitet, indem der Rege-lungsbedarf aufgezeigt und ein gesetzlicher Lösungsvorschlag präsentiert wird. Obwohl seit dem Abschluss der Dissertation wesentliche Änderungen in der Gesetzgebung vollzogen wurden, bleibt die Analyse in den Grundzügen relevant und die darauf gestützte Diskussion grundsätzlicher Fragen als Diskussionsgrundlage der disziplinarrechtlichen Ver-antwortlichkeit wesentlich. Die gewonnenen Erkenntnisse dienen dazu, interdisziplinäre Lö-sungen zu entwickeln, welche langfristig institutionelle Ordnung sicherzustellen und das Ver-trauen der Bevölkerung in staatliche Institutionen aufrecht zu erhalten vermögen.

description: This research examines the integration of commodity markets in Uganda. Weekly maize price data collected during 2001-2011in 13 regional markets is used to assess the degree to which these markets are cointegrated, i.e., market prices tend to share a long-term trend. A threshold autoregressive model is used to determine if symmetric or asymmetric threshold behavior is evident. All except one regional market is found to be linearly cointegrated with the central market. Threshold behavior only becomes apparent in the latter portion of time frame under analysis when 6 regional markets show evidence of thresholds (symmetric or asymmetric).

description: Simple quark models for the low lying vector mesons suggest a mixing between the u- and d-flavors and a violation of the isospin symmetry for the rho-omega system much stronger than observed. It is shown that the chiral dynamics, especially the QCD anomaly, is responsible for a restoration of the isospin symmetry in the rho-omega system.

Further tests of lepton flavour universality from the charged lepton energy distribution in $b\to c$ semileptonic decays: The case of $Λ_b\to Λ_c \ell \barν_\ell$

description: In a general framework, valid for any $H\to H'\ell^-\barν_\ell$ semileptonic decay, we analyze the $d^2Γ/(dωd\cosθ_\ell)$ and $d^2Γ/ (dωdE_\ell)$ distributions, with $ω$ being the product of the hadron four-velocities, $θ_\ell$ the angle made by the three-momenta of the charged lepton and the final hadron in the $W^-$ center of mass frame and $E_\ell$ the charged lepton energy in the decaying hadron rest frame. Within the Standard Model (SM), $ d^2Γ/(dωdE_\ell)\propto \left(c_0(ω)+c_1(ω)E_\ell/M+c_2(ω)E^2_\ell/M^2\right)$, with $M$ the initial hadron mass. We find that $c_2(ω)$ is independent of the lepton flavor and thus it is an ideal candidate to look for lepton flavor universality (LFU) violations. We also find a correlation between the $a_2(ω)$ structure function, that governs the $(\cosθ_\ell)^2$ dependence of $d^2Γ/(dωd\cosθ_\ell)$, and $c_2(ω)$. Apart from trivial kinematical and mass factors, the ratio of $a_2(ω)/c_2(ω)$ is a universal function that can be measured in any semileptonic decay, involving not only $b\to c$ transitions. These two SM predictions can be used as new tests in the present search for signatures of LFU violations. We also generalize the formalism to account for some new physics (NP) terms. Finally, in order to illustrate our findings, we apply our general framework to the $Λ_b\to Λ_c \ell \barν_\ell$ decay. We show that a measurement of $c_2$ (or $a_2$) for $τ$ decay would not only be a direct measurement of the possible existence of NP, but it would also allow to distinguish from NP fits to $b\to cτ\barν_τ$ anomalies in the meson sector, that otherwise give the same total and differential $dΓ/dω$ widths.
description: We show how NP scenarios predicting fully compatible ${\cal R}_D$, ${\cal R}_{D^*}$ and ${\cal R}_{\Lambda_c}$ ratios give rise to results for an observable, extracted from the charged lepton energy distribution in the $\Lambda_b \to \Lambda_c \ell \bar\nu_\ell$ decay, which are separated by 5$\sigma$.
