subject: Philosophy and religious studies

description: The history of doctrinal affiliations in the Gulf countries is one of the scarcely studied topics. In a time when religion and politics were deeply entwined Qatar adopted Wahhabism since the inauguration of its Sheikhdom and yet maintained a separate orientation in politics from the Saudi state. This study aims to explore the adoption of Wahhabism in Qatar through tracing early Saudi-Wahhabi attempts of expanding towards Qatar in the late eighteenth century until the time of its adoption by the founding Sheikh Qassim in the mid-nineteenth century. This adoption shall be studied through the vein of the private social, political, and economic context of that time period. The study also aims to define this adoption by Sheikh Qassim by examining a body of his formal and intimate writings, including his correspondence, poetry, and will. Using this material, a study of the interaction between the religious and the political shall be conducted, keeping in mind the Sheikh’s adherence to Wahhabism and its interaction with his political practices and alliances.

description: We construct the theory of non-abelian gauge antisymmetric tensor fields, which generalize the standard Yang-MIlls fields and abelian gauge p-forms. The corresponding gauge group acts on the space of inhomogeneous differential forms and it is shown to be a supergroup. The wide class of generalized Chern-Simons actions is constructed.

description: Contrary to the electric charge that generates the electric field, magnetic charge (namely magnetic monopoles) does not exist in the elementary electromagnetism. Consequently, magnetic flux lines only form loops and cannot have a source or a sink in nature. It is thus extraordinary to find that magnetic monopoles can be pictured conceptually in topological materials. Specifically in the 2D topological insulators, the topological invariant corresponds to the total flux of an effective magnetic field (the Berry curvature) over the reciprocal space.It is thus tempting to wrap the 2D reciprocal space into a compact manifold--a torus, and imagine the total flux to originate from magnetic monopoles inside the torus with a quantized total charge. However, such a physically appealing picture has not been realized quantitatively: other than their existence in a toy (actually misleading) picture, the properties of the magnetic monopoles remain unknown. Here, we will address this long-standing problem by hunting down the magnetic monopoles in the reciprocal $k$-space. We will show that a simple and physically useful picture will arrive upon analytically continuing the system to a third imaginary momentum space. We then illustrate the evolution of the magnetic monopoles across the topological phase transition and use it to provide natural explanations on: 1) discontinuous jump of integer topological invariants, 2) the semi-metallic nature on the phase boundary, and 3) how a change of global topology can be induced via a local change in reciprocal space.

description: Using ultra-high-frequency data extracted from the order flows of 23 stocks traded on the Shenzhen Stock Exchange, we study the empirical regularities of order placement in the opening call auction, cool period and continuous auction. The distributions of relative logarithmic prices against reference prices in the three time periods are qualitatively the same with quantitative discrepancies. The order placement behavior is asymmetric between buyers and sellers and between the inside-the-book orders and outside-the-book orders. In addition, the conditional distributions of relative prices in the continuous auction are independent of the bid-ask spread and volatility. These findings are crucial to build an empirical behavioral microscopic model based on order flows for Chinese stocks.

title: Downward Nominal Wage Rigidity Meets the Zero Lower Bound
Creators: name: Amano, Robert

Publisher: name: Bank of Canada
Year: 2017

description: We add downward nominal wage rigidity to a standard New Keynesian model with sticky prices and wages, where the zero lower bound on nominal interest rates is allowed to bind. We find that wage rigidity not only reduces the frequency of zero bound episodes but also mitigates the severity of corresponding recessions. As a result, previous studies abstracting from the presence of wage rigidity may have overemphasized the need for increasing the inflation target to offset the costs associated with hitting the zero bound. Moreover, our findings add to the recent debate on the presumed benefits of wage flexibility that has arisen in the aftermath of the Great Recession.

description: Nous intégrons la rigidité à la baisse des salaires nominaux à un modèle de type nouveau Keynésien standard à prix et salaires rigides dans lequel la borne du zéro des taux d’intérêt constitue parfois une contrainte. Nous constatons que la rigidité des salaires non seulement réduit la fréquence des épisodes où les taux d’intérêt nominaux atteignent la borne du zéro, mais atténue la gravité des récessions concomitantes. Il en découle que les études antérieures qui ne prenaient pas en compte la rigidité des salaires pourraient avoir accordé trop d’importance au relèvement de la cible d’inflation comme moyen de contrebalancer les coûts associés à l’atteinte de cette borne. De plus, nos constats contribuent à faire avancer le débat récent, lancé dans la foulée de la Grande Récession, sur les avantages présumés de la flexibilité des salaires.

description: We study a solvable QCD--like toy theory, a generalization of the Nambu--Jona-Lasinio model, which implements chiral symmetries of light quarks and heavy quark symmetry. The chiral symmetric and chiral broken phases can be dynamically tuned. This implies a parity doubled heavy--light meson system, corresponding to a $(0^-,1^-)$ multiplet and a $(0^+,1^+)$ heavy spin multiplet. Consequently the mass difference of the two multiplets is given by a Goldberger--Treiman relation and $g_A$ is found to be small. The Isgur--Wise function, $ξ(w)$, the decay constant, $f_B$, and other observables are studied.

All Abelian Symmetries of Landau-Ginzburg Potentials

description: We present an algorithm for determining all inequivalent abelian symmetries of non-degenerate quasi-homogeneous polynomials and apply it to the recently constructed complete set of Landau--Ginzburg potentials for $N=2$ superconformal field theories with $c=9$. A complete calculation of the resulting orbifolds without torsion increases the number of known spectra by about one third. The mirror symmetry of these spectra, however, remains at the same low level as for untwisted Landau--Ginzburg models. This happens in spite of the fact that the subclass of potentials for which the Berglund--Hübsch construction works features perfect mirror symmetry. We also make first steps into the space of orbifolds with $\ZZ_2$ torsions by including extra trivial fields.

An Analysis of Political Intolerance, Racism and Scapegoatism in Twentieth Century Germany
Creators: name: Hersh, Rebecca
Publisher: name: Carnegie Mellon University
Year: 1994
Subjects: History

description: Ideology is the source of all organized activity—there is no possibility of organized social activity without an internalized morality or ideology to legitimate it. Indeed, ideology is the transcendent phenomenon of everyday life, not as the causal or motivating factor in social activity, but as the link between organized mental activity and the organized social world. Ideology serves to legitimate realistic social activity, focus heterogeneous cognitive, moral, and wishful ambitions on the completion of social tasks, and define the range of appropriate behaviors in terms of those tasks. Ideology is the most important variable in the explanation of social stability and social change. Why does mankind have a much greater tendency change its ideology and produce feelings of fear and hatred in times of economic distress, hardship, or social upheaval? This paper attempts to answer this question and to provide socioeconomic, psychological, and political theory rationalizations for Germany's consistent history of racial and ethnic intolerance in the twentieth century. First, intolerance during pre- and post-World War II Germany are briefly discussed to provide a background and a greater understanding for what has occurred in more recent years. Since right extremist parties have once again entered parliamentary politics in the 1980s, it is necessary to examine the political focus and the socio-economic environment which helped mobilize voters and contributed to the success of the extreme right. Finally, the dramatic wave of intolerance and violence after the reunification of Germany is looked at and analyzed
Ghosts in the Phonograph: Tracking Black Canadian Postbody Poetics
Creators: name: Cleary, Emma
Publisher: name: Canadian Literature

description: Sound technologies enact cultural interventions and enable radical experiments of identity through the practice of stripping away, spinning, and splicing sounds — especially the sound of the human voice. This paper reads Black Canadian spoken word and turntable poetry for the symbolic use of sound technologies and other sonic schemas, focusing on Wayde Compton’s “The Reinventing Wheel” (2004) and Tanya Evanson’s “The African All Of It” (2013). In both of these works there is an emphasis upon the role of the body (and postbody) in the production of sound. I present both the spectral figure and sound recording technologies as postbody projections, and read the work of Compton and Evanson for transmissions that cross spatial, temporal, and body boundaries. The paper engages with posthumanist thought and the work of musicologist R. Murray Schafer to advance that sound technologies forge portals through time and space, as the dub plate reincarnates Compton’s disembodied, pre-recorded voice. Compton’s ghosts are quasi-material, zombies dancing in cargo holds — a reference to the Middle Passage — enacting a kinetic impulse capable of “moving the text” (103); Evanson’s acoustic experimentations with antiphony stress the kinetic and the sensory, and debinarize the relationship between speaker and audience. Finally, I argue that the ghostly emanation of postbody sounds from the turntable challenges culturally constructed binaries and forges a blended space for the celebration of plural, hybrid, and mobile identity formations, demolishing paradigms that work to enclose and encode Black Canada.

The radial structure of protostellar accretion disks: influence of jets

description: The radial structure of accretion disks is a fundamental issue regarding star and planet formation. Many theoretical studies, focussing on different aspects such as e.g. disk emissivity or ionization, have been conducted in the context of the Standard Accretion Disk (SAD) model, where no jet is present. We wish to calculate the structure of YSO accretion disks in an approach that takes into account the presence of the protostellar jets. The radial structure of these Jet Emitting Disks (JED) should then be compared to that of standard accretion disks. The analytical treatment used in this work is very similar to that of standard accretion disks but is using the parameter space of Magnetised Accretion-Ejection Structures that include the jet torque on the underlying disk. In this framework, the analytical expressions of key quantities, such as mid-plane temperatures, surface densities or disk aspect ratio are derived. It is found that JEDs present a structure very different from the SADs and that can be observationally tested. The implications on planet formation in the inner regions of accretion disks are briefly discussed. We also supply sets of analytical formulae, valid in different opacity regimes, for the disk quantities. These expressions can be readily used for any work where the disk structure is needed as an input for the model.

description: This essay expands our understanding of nineteenth-century Black Canadian writing by introducing the case of Peter Edward Susand. Susand's 1856 volume of poetry, published in what is now Kitchener, has been lost, raising the questions: how do we write about authors whose work hasn’t survived? Can we recuperate the literary practices of these individuals in the absence of their writings? Is it possible to marshal other evidence to reconstruct their literary networks and affiliations? What might we gain by undertaking such scholarly excavations? And how might doing so on behalf of those authors whose works haven't survived shift our understanding of nineteenth-century Black Canadian literary culture?

description: A dominating set $D$ of a graph $G$ is a set of vertices such that any vertex in $G$ is in $D$ or its neighbor is in $D$. Enumeration of minimal dominating sets in a graph is one of central problems in enumeration study since enumeration of minimal dominating sets corresponds to enumeration of minimal hypergraph transversal. However, enumeration of dominating sets including non-minimal ones has not been received much attention. In this paper, we address enumeration problems for dominating sets from sparse graphs which are degenerate graphs and graphs with large girth, and we propose two algorithms for solving the problems. The first algorithm enumerates all the dominating sets for a $k$-degenerate graph in $O(k)$ time per solution using $O(n + m)$ space, where $n$ and $m$ are respectively the number of vertices and edges in an input graph. That is, the algorithm is optimal for graphs with constant degeneracy such as trees, planar graphs, $H$-minor free graphs with some fixed $H$. The second algorithm enumerates all the dominating sets in constant time per solution for input graphs with girth at least nine.
title: Constrained Efficiency with Adverse Selection and Directed Search

description: Constrained efficient allocation (CE) is characterized in a model of adverse selection and directed search (Guerrieri, Shimer, and Wright (2010)). CE is defined to be the allocation that maximizes welfare, the ex-ante utility of all agents, subject to the frictions of the environment. When equilibrium does not achieve the first best (the allocation that maximizes welfare under complete information), then welfare in the CE is strictly higher than welfare in the equilibrium allocation. That is, equilibrium is not constrained efficient. Under some conditions, welfare in the CE even attains welfare in the first best. Finally, sufficient conditions are provided under which equilibrium is not constrained Pareto efficient, either. Cross-subsidization is the key to all these results. In an asset market application, the first best is shown to be implementable through tax schedules that are monotone in the asset prices.
description: Une allocation efficace opérée sous contrainte est caractérisée dans un modèle de sélection adverse et de prospection ciblée (Guerrieri, Shimer et Wright, 2010). Cette allocation est définie comme une allocation maximisant le bien-être (l’utilité espérée de tous les agents) en présence de frictions. Lorsque l’optimum atteint à l’équilibre n’est pas de premier rang (l’allocation qui maximalise le bien-être en situation d’information parfaite), le bien-être associé à l’allocation efficace est strictement supérieur au bien-être produit par l’allocation d’équilibre. Autrement dit, l’équilibre n’est pas efficace en présence de frictions. À certaines conditions, le bien-être associé à l’allocation efficace est même égal à celui de l’optimum de premier rang. Enfin, nous établissons les conditions sous lesquelles, en présence de frictions, l’équilibre n’est pas un optimum de Pareto. Des subventions croisées expliquent l’ensemble des résultats. Dans le cadre d’un marché d’actifs, nous montrons que l’optimum de premier rang est réalisable si des barèmes de taxes uniformes sont appliqués aux prix des actifs.

description: We study shadows cast by a certain class of rotating wormholes and point out the crucial role of a rotating wormhole throat in the formation of a shadow. Overlooking this crucial role of a wormhole throat has resulted incomplete results in the previous studies on shadows of the same class of rotating wormholes. We explore the dependence of the shadows on the spin of the wormholes. We compare our results with that of the Kerr black hole. With increasing values of the spin, the shapes of the wormhole shadows start deviating considerably from that of the black hole. Such considerable deviation, if detected in future observations, may possibly indicate the presence of a wormhole. In other words, the results obtained here indicate that, through the observations of their shadows, the wormholes which are considered in this work and have reasonable spin, can be distinguished from a black hole.

description: Die voranschreitende Digitalisierung macht auch nicht vor dem Bereich der Kalibrierung halt. Angetrieben auch aus der Industrie ist daher der digitale Kalibrierschein (DCC) entwickelt worden. Dabei handelt es sich um eine XSD-Datei (XML-Schema-Definition), die als eine Art Vorlage für digitale Kalibrierscheine für alle Messgrößen im XML-Format (Extensible Markup Language) dient. Eine Umsetzung braucht daher immer noch weitere, fachspezifische Festlegungen. Für die Maschineninterpretierbarkeit eines Dokuments ist jedoch eine vereinheitlichte Struktur vorteilhaft, die nicht alle Freiheiten des XSD-Schemas zulässt. Dadurch werden Interpretationsfehler zwischen erzeugendem und verarbeitendem System des DCCs vermieden. Der Verzicht auf die Flexibilität ermöglicht dabei einen effizienten, digital durchgehenden Datenaustausch mittels eines DCC, der mit vertretbarem Aufwand implementiert werden kann. Innerhalb jeder Metrologie-Community ist eine einheitliche Nutzung von Begriffen für die Kommunikation der Messergebnisse unabdingbar, weshalb die universell definierten XML-Elemente mit menschen- und maschineninterpretierbaren Informationen ergänzt werden müssen. Im Rahmen des DKD-Fachausschusses Länge wurde ein Good-Practice-Beispiel (GP) für einen DCC für Parallelendmaße entwickelt, den dieser Expertenbericht vorstellt.

description: We introduce a new approach for the estimation of high-dimensional factor models with regime-switching factor loadings by extending the linear three-pass regression filter to settings where parameters can vary according to Markov processes. The new method, denoted as Markov-switching three-pass regression filter (MS-3PRF), is suitable for datasets with large cross-sectional dimensions, since estimation and inference are straightforward, as opposed to existing regime-switching factor models where computational complexity limits applicability to few variables. In a Monte Carlo experiment, we study the finite sample properties of the MS-3PRF and find that it performs favourably compared with alternative modelling approaches whenever there is structural instability in factor loadings. For empirical applications, we consider forecasting economic activity and bilateral exchange rates, finding that the MS-3PRF approach is competitive in both cases.
description: Nous introduisons une nouvelle méthode d’estimation des modèles factoriels de large dimension avec changements de régimes en élargissant le filtre de régression linéaire à trois passages afin d’intégrer des paramètres qui peuvent varier en fonction de processus de Markov. Cette nouvelle méthode, appelée filtre de régression à trois passages avec changements de régimes markoviens (MS-3PRF), convient à des ensembles de données dotés d’importantes dimensions transversales car l’estimation et l’inférence s’y font directement. À l’inverse, les modèles factoriels à changements de régimes existants ne peuvent s’employer qu’avec un petit nombre de variables compte tenu de la complexité des algorithmes utilisés pour estimer ces modèles. Nous nous servons d’une expérience de Monte Carlo pour étudier les propriétés du filtre MS-3PRF sur un échantillon fini. Ce filtre donne de bons résultats par rapport aux autres méthodes de modélisation lorsque les pondérations factorielles présentent une instabilité structurelle. Pour l’application empirique, nous examinons la qualité des prévisions de l’activité économique et des taux de change bilatéraux : dans les deux cas, le filtre MS-3PRF se compare favorablement aux autres approches.
Unconventional superstring derived E$_{\bf 6}$ models and neutrino phenomenology

Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: Conventional superstring derived E$_6$ models can accommodate small neutrino masses if a discrete symmetry is imposed which forbids tree level Dirac neutrino masses but allows for radiative mass generation. Since the only possible symmetries of this kind are known to be generation dependent, we explore the possibility that the three sets of light states in each generation do not have the same assignments with respect to the 27 of $E_6$, leading to non universal gauge interactions under the additional $U(1)'$ factors for the known fermions. We argue that models realising such a scenario are viable, with their structure being constrained mainly by the requirement of the absence of flavor changing neutral currents in the Higgs sector. Moreover, in contrast to the standard case, rank 6 models are not disfavoured with respect to rank 5. By requiring the number of light neutral states to be minimal, these models have an almost unique pattern of neutrino masses and mixings. We construct a model based on the unconventional assignment scenario in which (with a natural choice of the parameters) $m_{\nut}\sim O(10)$eV is generated at one loop, $m_{\num}$ is generated at two loops and lies in a range interesting for the solar neutrino problem, and $\nue$ remains massless. In addition, since baryon and lepton number are conserved, there is no proton decay in the model. To illustrate the non-standard phenomenology implied by our scheme we also discuss a second scenario in which an attempt for solving the solar neutrino puzzle with matter enhanced oscillations and practically massless neutrinos can be formulated, and in which peculiar effects for the $\num$ --> $\nut$ conversion of the upward-going atmospheric neutrinos could arise as well.

description: Thousands of immigrants flooded the southwestern hills of Pennsylvania as early as the 1830s, continuing until the country's immigration laws tightened in the 1920s. Pittsburgh's strong industrial economy created numerous jobs and labor opportunities that greatly appealed to the masses. Thus, people of various ethnic groups moved to the "Steel City" in search of a new life. According to one observer of the city's social composition, this influx led to the unavoidable reorganization of social constructs.

description: We perform an exact renormalization-group analysis of one-dimensional 4-state clock models with complex interactions. Our aim is to provide a simple explicit illustration of the behavior of the renormalization-group flow in a system exhibiting a rich phase diagram. In particular we study the flow in the vicinity of phase transitions with a first-order character, a matter that has been controversial for years. We observe that the flow is continuous and single-valued, even on the phase transition surface, provided that the renormalized Hamiltonian exist. The characteristics of such a flow are in agreement with the Nienhuis-Nauenberg standard scenario, and in disagreement with the ``discontinuity scenario'' proposed by some authors and recently disproved by van Enter, Fernández and Sokal for a large class of models (with real interactions). However, there are some points in the space of interactions for which a renormalized Hamiltonian cannot be defined. This pathological behavior is similar, and in some sense complementary, to the one pointed out by Griffiths, Pearce and Israel for Ising models. We explicitly see that if the transformation is truncated so as to preserve a Hamiltonian description, the resulting flow becomes discontinuous and multivalued at some of these points. This suggests a possible explanation for the numerical results that motivated the ``discontinuity scenario''.

description: Obtaining realistic supersymmetry preserving vacua in the minimal renormalizable supersymmetric $Spin(10)$ GUT model introduces considerations of the non-trivial topology of the vacuum manifold. The $D$-parity of low energy unification schemes gets lifted to a one-parameter subgroup $U(1)_D$ of $Spin(10)$. Yet, the choice of the fields signaling spontaneous symmetry breaking leads to disconnected subsets in the vacuum manifold related by the $D$-parity. The resulting domain walls, existing due to topological reasons but not stable, are identified as topological pseudodefects. We obtain a class of one-parameter paths connecting $D$-parity flipped vacua and compute the energy barrier height along the same. We consider the various patterns of symmetry breaking which can result in either intermediate scale gauge groups or a supersymmetric extension of the Standard Model. If the onset of inflation is subsequent to GUT breaking, as could happen also if inflation is naturally explained by the same GUT, the existence of such pseudodefects can leave signatures in the CMB. Specifically, this could have an impact on the scale invariance of the CMB fluctuations and LSS data at the largest scale.

description: The strength of an educational system largely depends upon the quality of teachers. A quality teacher is the major criterion for offering the quality education. Teacher has always been considered as one of the noblest human being and as second parent of students. Students are generally influenced by their teachers, because they spend most of their time under the guidance of teachers in schools Rashaan (2010, p.4) describes that teachers are professionally trained and certificated to manage and control instructional process in the school. For teaching learning activities, to take place, teacher must prepare lesson plans, produces instructional materials and adopts appropriate teaching strategies to achieve instructional objectives. For effective learning, a teacher needs to be equipped with all these skills and attitudes by which he can help his students to learn.

description: We investigate the effects of the spontaneous CP violation at finite temperature in the Minimal Supersymmetric Standard Model on the baryogenesis at the weak scale. After a brief discussion of the case in which the electroweak phase transition is of the second order, we study in details the baryogenesis scenario when the transition proceeds via bubble nucleation. We show that the space-time dependent phase for the Higgs vacuum expectation values coming from the spontaneous CP violation can give rise to a efficient generation of baryon number inside the bubble walls if the superpotential parameters and the soft supersymmetry breaking ones are complex. However we find that in order to get the observed value for the baryon asymmetry of the universe the phases of such parameters can be as small as $10^{-5}$, giving rise to an electron dipole moment of the neutron well below the current experimental limit. Moreover a light Higgs pseudoscalar is needed, and an upper bound on its mass is obtained.

description: We investigate the implications of a sterile neutrino on the physics potential of the proposed experiment DUNE and future runs of NO$ν$A using latest NO$ν$A results. Using combined analysis of the disappearance and appearance data, NO$ν$A reported preferred solutions at normal hierarchy (NH) with two degenerate best-fit points one in the lower octant (LO) and $δ_{13}$ = 1.48$π$ and other in higher octant (HO) and $δ_{13}$ = 0.74$π$. Another solution of inverted hierarchy (IH) which is 0.46$σ$ away from best fit was also reported. We discuss chances of resolving these degeneracies in the presence of sterile neutrino.

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.

Experimental investigation of dynamical structures formation due to flowing complex plasma past an obstacle

description: We report the experimental observation of dynamical behavior of flowing complex plasma past a spherical obstacle. The experiment has been carried out in a $Π$-shaped DC glow discharge experimental device using kaolin particles as the dust component in a background of Argon plasma. A stationary dust cloud is formed by maintaining the pumping speed and gas flow rate. A spherical obstacle vertically mounted on the cathode tray acts as an obstacle to the flow of dust particles. The controlled dust flow is generated by reducing the mass flow of the neutrals through a mass flow controller. The flowing dust particles are repelled by the electrostatic field of the negatively charged sphere and a microparticle free region (dust void) is formed surrounding the obstacle. The far particles are attracted towards the floating obstacle and reflected back when they have arrived at a minimum distance, causing a ring shaped structure around the obstacle. We characterize the shape of this structure over a range of dust flow speeds and obstacle biases. For a supersonic flow of dust fluid around a negatively biased obstacle, a bow shock is formed on the upstream side of the sphere, while the generation of wave structures is observed on the downstream side for a particular range of flow velocities. Reynolds numbers in this case is estimated as $R_e \gtrsim 50$. This wave structure reminds of the beginning of the formation of a Von-Kármán vortex street. A physical picture for the observed structure based on ion-drag, neutral streaming and electric forces is discussed.

Semiclassical Tunneling in 1+1 Dimensional String Theory

description: We describe time-dependent tunneling of massless particles in 1+1 dimensional string field theory. Polchinski's description of the classical solutions in terms of the Fermi sea is used to identify the leading instanton contribution connecting the two half-lines. The field theory lagrangian is proportional to $1/g^2$, where $g$ is the string coupling constant, but the $S$-matrix for tunneling from one half-line to the other behaves as $\exp(-C/g)$. We note the constant~$C$ involves curious boundary contributions and observe that a prescription connecting the two half-lines unifies treatments of the Fermi level above and below the barrier. We also note the relation to recent work of Brustein and Ovrut.

title: Accounting for Real Exchange Rates Using Micro‐Data
Creators: name: Crucini, Mario J.
name: Landry, Anthony
Publisher: name: Bank of Canada
Year: 2017

description: The classical dichotomy predicts that all of the time-series variance in the aggregate real exchange rate is accounted for by non-traded goods in the consumer price index (CPI) basket because traded goods obey the Law of One Price. In stark contrast, Engel (1999) claimed the opposite: that traded goods accounted for all of the variance. Using micro-data and recognizing that final good prices include both the cost of the goods themselves and local, non-traded inputs into retail such as labor and retail space, our work re-establishes the conceptual value of the classical dichotomy. We also carefully show the role of aggregation, consumption expenditure weighting and assignment of covariance terms in the differences between our findings and those of Engel.
description: Selon la dichotomie classique, les biens non échangeables du panier de l’indice des prix à la consommation (IPC) expliquent intégralement la variance au sein des séries chronologiques du taux de change réel agrégé, car les biens échangeables suivent la loi du prix unique. Engel (1999) soutient à l’inverse que ce sont les biens échangeables qui expliquent toute la variance. Nous rétablissons la valeur conceptuelle de la dichotomie classique en nous appuyant sur des microdonnées et en reconnaissant que les prix des biens finaux renferment le coût même des biens et les coûts d’intrants locaux non échangeables, comme ceux du travail et des espaces commerciaux, qui sont liés au commerce de détail. Nous démontrons en outre que l’agrégation, la pondération des dépenses de consommation et la répartition des termes de covariance jouent un rôle dans les différences observées entre nos résultats et ceux d’Engel.
Differentiability of the volume of a region enclosed by level sets

description: The level of a function f on an n-dimensional space encloses a region. The volume of a region between two such levels depends on both levels. Fixing one of them the volume becomes a function of the remaining level. We show that if the function f is smooth, the volume function is again smooth for regular values of f. For critical values of f the volume function is only finitely differentiable. The initial motivation for this study comes from Radiotherapy, where such volume functions are used in an optimization process. Thus their differentiability properties become important.

Majorana neutrino masses in the scenario of gauge-Higgs unification

description: In this paper we consider possible mechanisms to generate small Majorana neutrino masses for active neutrinos in the scenario of gauge-Higgs unification, a candidate for physics beyond the standard model. We stress that it is non-trivial to find a gauge-invariant operator, responsible for the Majorana masses, which is the counterpart of the well-known SU(2)$_L \times$ U(1)$_Y$ invariant higher-mass-dimensional ($d = 5$) operator. As the first possibility we discuss the seesaw mechanism by assigning leptonic fields to the adjoint representation of the gauge group, so that a $d = 5$ gauge-invariant operator can be formed. It turns out that the mechanism leading to the small Majorana masses is the admixture of the Type I and Type III seesaw mechanisms. As the second possibility, we consider the case where the relevant operator has $d = 7$, by introducing a matter scalar belonging to the fundamental representation of the gauge group. Reflecting the fact that the mass dimension of the operator is higher than usually expected, the Majorana masses are generated by a "double seesaw mechanism."
