description: We use the POMWIG Monte Carlo generator to predict the cross-sections for double diffractive higgs and di-photon production at the Tevatron and LHC. We find that the higgs production cross-section is too small to be observable at Tevatron energies, and even at the LHC observation would be difficult. Double diffractive di-photon production, however, should be observable within one year of Tevatron Run II.

description: This article describes a new command, gformula, that is an implementation of the g-computation procedure. It is used to estimate the causal effect of time-varying exposures on an outcome in the presence of time-varying confounders that are themselves also affected by the exposures. The procedure also addresses the related problem of estimating direct and indirect effects when the causal effect of the exposures on an outcome is mediated by intermediate variables, and in particular when confounders of the mediator–outcome relationships are themselves affected by the exposures. A brief overview of the theory and a description of the command and its options are given, and illustrations using two simulated examples are provided.

description: BMN operators are characterized by the fact that they have infinite R-charge and finite anomalous dimension in the BMN double scaling limit. Using this fact, we show that the BMN operators close under operator product expansion and form a sector in the N=4 supersymmetric Yang-Mills theory. We then identify short-distance limits of general BMN n-point correlators, and show how they correspond to the pp-wave string interactions. We also discuss instantons in the light of the pp-wave/SYM correspondence.

description: Despite the availability of ever more data enabled through modern sensor and computer technology, it still remains an open problem to learn dynamical systems in a sample-efficient way. We propose active learning strategies that leverage information-theoretical properties arising naturally during Gaussian process regression, while respecting constraints on the sampling process imposed by the system dynamics. Sample points are selected in regions with high uncertainty, leading to exploratory behavior and data-efficient training of the model. All results are finally verified in an extensive numerical benchmark.
Quantum chaos and fractals with atoms in cavities

description: We study the coupled translational, electronic, and field dynamics of the combined system "a two-level atom + a single-mode quantized field + a standing-wave ideal cavity". We derive Hamilton -- Schrödinger equations for probability amplitudes and averaged position and momentum of a point-like atom interacting with the quantized field in a standing-wave cavity. They constitute, in general, an infinite-dimensional set of equations with an infinite number of integrals of motion which may be reduced to a dynamical system with four degrees of freedom if the quantized field is supposed to be initially prepared in a Fock state. This system is found to produce semiquantum chaos with positive values of the maximal Lyapunov exponent. At large values of detuning $|δ|\gg 1$, the Rabi atomic oscillations are usually shallow, and the dynamics is found to be almost regular. The Doppler -- Rabi resonance, deep Rabi oscillations that may occur at any large value of $|δ|$ to be equal to $|αp_0|$, is found numerically and described analytically (with $α$ to be the normalized recoil frequency and $p_0$ the initial atomic momentum). Two gedanken experiments are proposed to detect manifestations of semiquantum chaos in real experiments. In the chaotic regime values of the population inversion $z_{out}$, measured with atoms after transversing a cavity, are so sensitive to small changes in the initial inversion $z_{in}$ that the probability of detecting any value of $z_{out}$ in the admissible interval becomes almost unity in a short time. Chaotic wandering of a two-level atom in a quantized Fock field is shown to be fractal. Fractal-like structures, typical for chaotic scattering, are numerically found in the dependence of the time of exit of atoms from the cavity on their initial momenta.

description: In this article, we describe the estimation of linear regression models with uncertainty about the choice of the explanatory variables. We introduce the Stata commands bma and wals, which implement, respectively, the exact Bayesian model-averaging estimator and the weighted-average least-squares estimator developed by Magnus, Powell, and Pr¨ufer (2010, Journal of Econometrics 154: 139–153). Unlike standard pretest estimators that are based on some preliminary diagnostic test, these model-averaging estimators provide a coherent way of making inference on the regression parameters of interest by taking into account the uncertainty due to both the estimation and the model selection steps. Special emphasis is given to several practical issues that users are likely to face in applied work: equivariance to certain transformations of the explanatory variables, stability, accuracy, computing speed, and out-of-memory problems. Performances of our bma and wals commands are illustrated using simulated data and empirical applications from the literature on model-averaging estimation.
Goldstone Boson Effects on Vacuum Decay

description: We study the effects of Goldstone modes on the stability of the vacuum in a $U(1)$ theory for a complex scalar field. The dynamics of the field resemble those of Keplerian motion in the presence of time-dependent friction, whose equations of motion imply a conserved quantity, $L$, reminiscent of conserved angular momentum. They also imply a persistent infinite barrier at $ρ=0$ and a divergent field value at the origin of coordinates in flat spacetime, rendering any solution physically unattainable. However, in a spacetime punctured at the origin of coordinates, we find finite-action solutions to the equations of motion, which correspond to the size of the hole $a_0$, which in turn determines the tunneling point $ρ_0$ and $L$. We find that the rates of vacuum decay get drastically enhanced by many orders of magnitude for all possible orderings in which the false and true vacua are placed in the potential. Finally, we show how Goldstone modes provide the necessary energy to overcome drag forces yielding finite-action solutions for any potential, including those that no such solutions exist for real scalar fields.

description: The behavior of an object-oriented software system is notoriously hard to understand from the source code alone. The main reason is the large gap between the program's static structure and its actual runtime behavior. Features inherent to object-orientation, like object aliasing and late binding, - while providing a high degree of expressiveness to model an application domain - make programs hard to understand, maintain, and analyze. Complementary to static analysis, dynamic analysis can help to close this gap by investigating the properties of a running program. The state of the art in dynamic analysis focuses on investigating runtime control flow and structures of object graphs, but a thorough analysis of how objects are passed through a system is missing. Tracking how object references are transferred, however, is essential to analyze the dependencies introduced by object aliasing. In this dissertation we propose Object Flow Analysis, our approach to track object flow by explicitly representing object references and reference transfer. Object Flow Analysis provides an effective and original way of analyzing and runtime monitoring dependencies introduced by object aliasing. To validate Object Flow Analysis, we propose three different reverse engineering applications that, based on Object Flow Analysis, reason about aliasing dependencies in object-oriented programs. Yet Object Flow Analysis extends beyond traditional reverse engineering applications. A key contribution of our work is that we advance the state of the art in back-in-time debugging by proposing and providing an implementation of the concept of Object Flow Analysis in a high-level language virtual machine.

description: Treatment effects may vary with the observed characteristics of the treated, often with important implications. In the context of experimental data, a growing literature deals with the problem of specifying treatment interaction terms that most effectively capture this variation. Some results of this literature are now implemented in Stata. With nonexperimental (observational) data, and in particular when selection into treatment depends on unmeasured factors, treatment effects can be estimated using Stata’s treatreg command. Though not originally designed for this purpose, treatreg can be used to consistently estimate treatment interaction parameters. With interactions, however, adjustments are required to generate predicted values and estimate the average treatment effect. In this article, we introduce commands that perform this adjustment for multiplicative interactions, and we show the required adjustment for more complicated interactions.

description: We derive a general expression for the gauge invariant mass (m_G) for an Abelian gauge field, as induced by vacuum polarization, in 1+1 dimensions. From its relation to the chiral anomaly, we show that m_G has to satisfy a certain quantization condition. This quantization can be, on the other hand, explicitly verified by using the exact general expression for the gauge invariant mass in terms of the fermion propagator. This result is applied to some explicit examples, exploring the possibility of having interesting physical situations where the value of $m_G$ departs from its canonical value. We also study the possibility of generalizing the results to the 2+1 dimensional case at finite temperature, showing that there are indeed situations where a finite and non-vanishing gauge invariant mass is induced.

description: In the first paper in this series, we introduced "persistent gravitational wave observables" as a framework for generalizing the gravitational wave memory effect. These observables are nonlocal in time and nonzero in the presence of gravitational radiation. We defined three specific examples of persistent observables: a generalization of geodesic deviation that allowed for arbitrary acceleration, a holonomy observable involving a closed curve, and an observable that can be measured using a spinning test particle. For linearized plane waves, we showed that our observables could be determined just from one, two, and three time integrals of the Riemann tensor along a central worldline, when the observers follow geodesics. In this paper, we compute these three persistent observables in nonlinear plane wave spacetimes, and we find that the fully nonlinear observables contain effects that differ qualitatively from the effects present in the observables at linear order. Many parts of these observables can be determined from two functions, the transverse Jacobi propagators, and their derivatives (for geodesic observers). These functions, at linear order in the spacetime curvature, reduce to the one, two, and three time integrals of the Riemann tensor mentioned above.

A Grammar of Garifuna

Publisher: name: Universität Bern
Year: 2016
Subjects: 410 Linguistics

description: This dissertation is a grammatical description of Garifuna, and is the first booklength treatment of the entire grammatical system of this language. The language is spoken in Central America and belongs to the Arawak language family, which is the largest in South America. The book consists of 15 chapters, with Chapter 1 being an introduction to the study, the language and its speakers, fieldwork carried out by the author and the database upon which the analyses are based. The book is structured in a similar way to most grammatical descriptions, starting with phonology (Chapter 2), moving on to morphology (chapters 3-10), and lastly syntax (Chapters 11-14) with Chapter 15 treating the special issue of genderlects. There is also an appendix containing three texts transcribed, glossed and translated. The grammar makes important constributions in at least two ways: Garifuna is an endangered language, and its description and documentation will help preserve knowledge of the language for the future benefit of speakers and their descendants, as well as language scholars. Secondly, Garifuna displays a number of linguistic features which are cross-linguistically rare, and will be of interests to language typologists, and to linguists more generally, including: gendered speech (or genderlects), possessive classifiers encoding the relationship between possessor and the possessed, verb forms underspecified for tense and aspect accounting for the majority of verb tokens, suppletive verb forms (high frequency items) based on borrowed verbs.

On the Plumbing Structure of Fibre Surfaces
Creators: name: Misev, Filip
Publisher: name: Universität Bern
Year: 2016
Subjects: 510 Mathematics

description: This thesis is situated in the mathematical field of low-dimensional topology and is concerned with a particular class of knots and links known as fibred links. A link L in the three-sphere is fibred if its complement admits a fibration over the circle with fibres the interiors of Seifert surfaces for L. These surfaces, called fibre surfaces, are our main objects of study. For example, all torus links and all positive braid links are fibred. The simplest example of a fibred link is the Hopf link; its fibre surface is an annular band with a full twist. Using a geometric operation called plumbing, Hopf bands can be glued together so as to form more complicated fibre surfaces. The reverse operation, deplumbing, consists in removing a Hopf band from a fibre surface. It amounts to cutting that fibre surface along a proper arc. By a theorem of Giroux and Goodman's, every fibre surface has a plumbing structure: it can be obtained from the standard disk by plumbing and deplumbing some number of Hopf bands. Our main results concern the (non-)uniqueness of the plumbing structure of a given fibre surface. Specifically, we study the cases of torus links and positive arborescent Hopf plumbings. Among these, we characterise the links arising from simple plane curve singularities by the finiteness of proper arcs that correspond to deplumbing a Hopf band.

description: A decomposed generalised Chaplygin gas (gCg) with energy flux from dark energy to dark matter, represented by a negative value for the gas parameter $α$, is shown to alleviate the tension between EDGES data and the cosmological standard model. Using EDGES data and employing a Bayesian statistical analysis, the agreement with the standard model is only marginal. However, if $α$ is negative enough the gCg fits remarkably well the data, even in combination with SNe Ia datasets. On the other hand, when the CMB and BAO acoustic scales are included the preferred value for $α$ is near zero, implying that a small deviation from $Λ$CDM is predicted.

description: We discuss a recently demonstrated type of microwave spectroscopy of trapped ultra-cold atoms known as "echo spectroscopy" [M.F. Andersen et. al., Phys. Rev. Lett., in press (2002)]. Echo spectroscopy can serve as an extremely sensitive experimental tool for investigating quantum dynamics of trapped atoms even when a large number of states are thermally populated. We show numerical results for the stability of eigenstates of an atom-optics billiard of the Bunimovich type, and discuss its behavior under different types of perturbations. Finally, we propose to use special geometrical constructions to make a dephasing free dipole trap.

description: The purpose of this paper is to test specific hypotheses about the detenninants of temporary ruralto- urban migration (circulation) by male heads of households for the putpose of engaging in wage employmenL Data from a sample of 145 rural households located in the central Mexican highlands are used to estimate the model. The circulation equation is formulated as a polychotomous, ordered-response model and is estimated using logistic regression. The results of the model suggest that males' level of education and previous circulation experience have a positive and significant impact on the probability of circulation. By comparison, land has a negative effect, and ecooomic status has a U-shaped effect. Age and the nmnber of adults in the household are fotmd to have a statistically weak association with the dependent variable.

This canonical ensemble framework corresponds to the experimental conditions, the number of particles being fixed for each experimental sequence. We show that, in the strongly interacting regime, the contact rescaled by the contact at the Tonks-Girardeau limit is an universal function of two parameters, the rescaled interaction strength and temperature. This means that all pair and correlation effects in the Tan's contact are embedded in the Tan's contact in the Tonks-Girardeau limit.

description: Traditionally, water policy has focused on coordinating the public effort required to fuel economic growth by supplying water services demanded as a result of the progress in the many areas of the economy. Under this supply-oriented paradigm, population growth and the improvement of living standards brought about by development have driven water demand up and the pressures over water resources have escalated. The failure to acknowledge the limited availability of water and to decouple economic development from water demand has resulted in a water dependent growth model that in many areas is currently threatened by increasing scarcity and more frequent and intense droughts. Consequently, there is an urgent need to use sparse water resources in a sustainable and efficient way. This demands a comprehensive assessment of water productivity dynamics as well as of the linkages among economic sectors in order to calculate the actual costs of eventual water reallocations to the environment and establish priorities in the design of strategic actions such as river basin or drought management plans. However, available studies only offer static analyses that are insufficient to attain the dual objective of reverting current water scarcity trends without impairing economic growth. This paper develops a methodology based on the Hypothetical Extraction Method to estimate inter-temporal indirect (i.e., including intersectoral linkages) water productivity values. The method is applied in the Spanish region of Castile and León for the period 2000-2006. The intensive use and the low water productivity found for agriculture confirms the intuition that this sector has to play a fundamental role in any water saving policy. However, the relevant linkages between agriculture and the rest of the economy, which acts as an indirect consumer of water for irrigation, may complicate the finding of a Pareto improvement in water allocation. Results also show increasing returns to scale in the manufacturing industry and the service sector, which may be regarded as an evidence of the existence of a Verdoorn’s Law for water.

On the signature of positive braids and adjacency for torus knots
Creators: name: Feller, Peter
Publisher: name: Universität Bern
Year: 2014
Subjects: 510 Mathematics

description: The objects of study in this thesis are knots. More precisely, positive braid knots, which include algebraic knots and torus knots. In the first part of this thesis, we compare two classical knot invariants - the genus g and the signature σ - for positive braid knots. Our main result on positive braid knots establishes a linear lower bound for the signature in terms of the genus. In the second part of the thesis, a positive braid approach is applied to the study of the local behavior of polynomial functions from the complex affine plane to the complex numbers. After endowing polynomial function germs with a suitable topology, the adjacency problem arises: for a fixed germ f, what classes of germs g can be found arbitrarily close to f? We introduce two purely topological notions of adjacency for knots and discuss connections to algebraic notions of adjacency and the adjacency problem.
Three essays on prices and selection

description: Competitive Market Segmentation Abstract In a two-firm model where each firm sells a high-quality and a low-quality version of a product, customers differ with respect to their brand preferences and their attitudes towards quality. We show that the standard result of quality-independent markups crucially depends on the assumption that the customers' valuation of quality is identical across firms. Once we relax this assumption, competition across qualities leads to second-degree price discrimination. We find that markups on low-quality products are higher if consuming a low-quality product involves a firm-specific disutility. Likewise, markups on high-quality products are higher if consuming a high-quality product creates a firm-specific surplus. Selection upon Wage Posting Abstract We discuss a model of a job market where firms announce salaries. Thereupon, they decide through the evaluation of a productivity test whether to hire applicants. Candidates for a job are locked in once they have applied at a given employer. Hence, such a market exhibits a specific form of the bargain-then-ripoff principle. With a single firm, the outcome is efficient. Under competition, what might be called "positive selection" leads to market failure. Thus our model provides a rationale for very small employment probabilities in some sectors. Exclusivity Clauses: Enhancing Competition, Raising Prices Abstract In a setting where retailers and suppliers compete for each other by offering binding contracts, exclusivity clauses serve as a competitive device. As a result of these clauses, firms addressed by contracts only accept the most favorable deal. Thus the contract-issuing parties have to squeeze their final customers and transfer the surplus within the vertical supply chain. We elaborate to what extent the resulting allocation depends on the sequence of play and discuss the implications of a ban on exclusivity clauses.

description: In this paper, we use semi-structured interviews with firm representatives and original survey data to study the factors influencing farmers’ participation in modern supply chains in the Ecuadorian blackberry sector. Previous research has emphasized the important role of farm size and non-farm assets enabling participation in these chains. Going beyond this scope of analysis, we argue that farmers’ social networks can be an important avenue to facilitate inclusion. Using different probit model specifications, we find that individual farmers’ social networks are important determinants for participation in modern supply chains in an environment characterized by a homogenous farm sector. Further research is needed to explore the specific pathways through which social networks exert their influence.

description: Dark matter substructure can contribute significantly to local dark matter searches and may provide a large uncertainty in the interpretation of those experiments. For direct detection experiments, sub-halos give rise to an additional dark matter component on top of the smooth dark matter distribution of the host halo. In the case of dark matter capture in the Sun, sub-halo encounters temporarily increase the number of captured particles. Even if the encounter happened in the past, the number of dark matter particles captured by the Sun can still be enhanced today compared to expectations from the host halo as those enhancements decay over time. Using results from an analytical model of the sub-halo population of a Milky Way-like galaxy, valid for sub-halo masses between $10^{-5}\,M_\odot$ and $10^{11}\,M_\odot$, we assess the impact of sub-halos on direct dark matter searches in a probabilistic way. We find that the impact on direct detection can be sizable, with a probability of $\sim 10^{-3}$ to find an $\mathcal{O}(1)$ enhancement of the recoil rate. In the case of the capture rate in the Sun, we find that $\mathcal{O}(1)$ enhancements are very unlikely, with probability $\lesssim 10^{-5}$, and are even impossible for some dark matter masses.

description: Giving up the assumption of the gaugino mass unification at the GUT scale, the latest LEP and Tevatron data still allow the lightest supersymmetric Higgs to have a large branching fraction into invisible neutralinos. Such a Higgs may be difficult to discover at the LHC and is practically unreachable at the Tevatron. We argue that, for some of these models to be compatible with the relic density, light sleptons with masses not far above the current limits are needed. There are however models that allow for larger sleptons masses without being in conflict with the relic density constraint. This is possible because these neutralinos can annihilate efficiently through a Z-pole. We also find that many of these models can nicely account, at the 2σlevel, for the discrepancy in the latest g-2 measurement. However, requiring consistency with the g-2 at the 1σlevel, excludes models that lead to the largest Higgs branching fraction into LSP's. In all cases one expects that even though the Higgs might escape detection, one would have a rich SUSY phenomenology even at the Tevatron, through the production of charginos and neutralinos.

description: L'ensemble de ces notes ont été crée par John Baldwin lors d'une de ses premières périodes de résidence à Paris. Ces documents comprennent tous les magistri qu’il avait pu rencontrer dans ses sources. Aux XIIème et XIIIème siècles, les universités n'existant pas encore, le titre de magister s'il évoque certainement une compétence n'est pas rattaché de façon systématique au passage par les écoles. De surcroît, les magistris sont le plus souvent désignés par leur seul prénom. La lecture de ces données est donc difficile et suppose un long travail pour tenter d'identifier un individu auquel on pourrait rattacher plusieurs mentions. John Baldwin avait donc renoncé à utiliser ces données pour donner un prolongement à sa magnifique étude sur les gradués d'université et leur emploi par les Capétiens et les Plantagenêts. Néanmoins, il a conservé ces données et elles sont potentiellement très utile dans le cadre de Studium, comme le sont toutes les mentions dans les volumes des Fasti Ecclesiae Gallicanae de chanoines portant ce titre de magister sans autres précisions. L'ampleur des dépouillements rend ces données très utiles et nous devons une grande reconnaissance à John Baldwin pour avoir pris la peine de faire photocopier ses fiches et de nous les avoir transmises amicalement.
Les données ainsi que les images des fiches sont accessibles sur le site Internet à l'adresse suivante : http://studium-baldwin.lamop.fr/.
Les transcriptions des fiches ont été effectuées par des étudiants de Paris 1 Panthéon - Sorbonne mais elles n'ont pas été corrigées par la suite.

description: We consider a simple model of a bistable system under the influence of multiplicative noise. We provide a path integral representation of the overdamped Langevin dynamics and compute conditional probabilities and escape rates in the weak noise approximation. The saddle-point solution of the functional integral is given by a diluted gas of instantons and anti-instantons, similarly to the additive noise problem. However, in this case, the integration over fluctuations is more involved. We introduce a local time reparametrization that allows its computation in the form of usual Gaussian integrals. We found corrections to the Kramers' escape rate produced by the diffusion function which governs the state dependent diffusion for arbitrary values of the stochastic prescription parameter. Theoretical results are confirmed through numerical simulations.

Dein Gott ist ein Esel. Griechische und römische Tierkarikaturen als Spiegel antiker Wertvorstellungen

description: Die Doktorarbeit “Dein Gott ist ein Esel. Griechische und römische Tierkarikaturen als Spiegel antiker Wertvorstellungen” hat sowohl die lange und intensive Beziehung zwischen Mensch und Tier als auch das antike Humorverständnis zum Thema. Trotz seiner verschiedenen Rollen als Helfer und Freund blieb (und bleibt) das Tier der Stereotyp des ‚Anderen’, das Gegenbild, das alle Menschen teilen. Das Lachen und damit die Karikatur wiederum helfen uns, zu reflektieren und Distanz zu den Dingen und vielleicht zu uns selbst zu gewinnen. Tierkarikaturen sind deshalb besonders geeignet, ein Spiegel menschlicher Fehler und Schwächen zu sein. In der Regel handelt es sich bei den antiken Tierkarikaturen um Bilder von Menschen, die tiergestaltig ‚verzerrt’ sind, zum Beispiel ein Lehrer mit dem Äusseren eines Esels. Solche Darstellungen sind ab dem 6. Jh. v. Chr. zu finden und werden in hellenistischer und römischer Zeit häufiger, wo der Fokus der Arbeit liegt. Meist sind es Terrakotta- oder Bronzefiguren, die verschiedenen gesellschaftlichen Bereichen zugeordnet werden können wie Religion, Politik, Freizeit usw. Unter Berücksichtigung des spezifischen kulturellen und funktionalen Kontextes jedes Stückes sowie zeitgenössischen schriftlichen Quellen wird die Bedeutung dieser Karikaturen erarbeitet.
description: The doctoral thesis “Your god is an ass. Greek and Roman caricatures of animals as a mirror of ancient values” deals with the history of humour as well as with the long and intense relationship of man and animal. Despite of its different roles as assistant and friend the animal always remains “the other” as a stereotype, the contrast all human beings share. Laughter and therefore caricature on the other hand help us to gain distance to things, to reflect on them and, at the same time, on ourselves. In consequence, caricatures of animals are especially suitable to be a mirror that shows human weakness and faults. Animal caricatures usually are pictures of animals acting like men, for example an ass being a teacher. They have existed since the 6th century BC but become more frequent in Hellenistic and Roman times, where the study focuses. They are represented mostly in terracotta and bronze figurines and can be allocated to different social areas like myth and religion, politics and education, leisure and so on. Considering the different cultural and functional contexts of each example as well as contemporary literary sources, the meaning of the selected caricatures is found.

description: Synchronized artificial insemination was used to inseminate cows using different types of sire genetics, including low-accuracy, calving-ease, and high-accuracy. These three sire groups were compared to calves born to cows bred using natural service. We found substantial production efficiency gains, carcass merit improvement, and economic value for calves of cows bred using a synchronized artificial insemination program with highaccuracy semen. The economic advantage of the high-accuracy sire group of calves was computed to be in the neighborhood of $40 to $80/head, relative to the natural service sire group of calves.
