description: Several supersymmetric models with extended gauge structures, motivated by either grand unification or by neutrino mass generation, predict light doubly-charged Higgsinos. In this work we study productions and decays of doubly-charged Higgsinos present in left-right supersymmetric models, and show that they invariably lead to novel collider signals not found in the minimal supersymmetric model (MSSM) or in any of its extensions motivated by the μproblem or even in extra dimensional theories. We investigate their distinctive signatures at the Large Hadron Collider (LHC) in both pair-- and single--production modes, and show that they are powerful tools in determining the underlying model via the measurements at the LHC experiments.

description: Flexammina gen. nov.
 Etymology. ‘ Flex ’ from English ‘flexible’ denoting the plasticity of the test shape; ‘ ammina ’—from the Greek ‘psammon’ meaning ‘sand’—refers to the agglutinated mineral material covering the test.
 Type species. Flexammina islandica.
 Diagnosis. Test free or attached, monothalamous. The test shape is subspherical or elongated when free, domelike when attached; aperture subcircular to irregular, surrounded by a short collar; test wall flexible, formed by a thick layer of mineral grains with an underlying layer of organic material.
 Phylogenetic position. The type species F. islandica branches in the clade M of monothalamous foraminifera, based on the phylogenetic analysis of SSU rDNA gene sequences.
 Remarks. There are some monothalamids that morphologically resemble Flexammina. Of these, Leptammina Cedhagen et al. (2009) is a genus from the deep Weddell Sea, with a similar test morphology possessing a flexible spherical test composed of fine mineral particles and a collared aperture. However, there is no evidence that Leptammina is able to assume attached dome-shaped form; its test wall agglutination is more uniform and finer. Moreover, this genus is very distant genetically, belonging to the ‘clade C’ of monothalamids. Some species of Hemisphaerammina Loeblich and Tappan (1957) and Crithionina Goës (1894) superficially resemble the attached form of Flexammina by the test shape and the character of their test wall agglutination. However, their tests lack the aperture on the upper surface and the basal test wall in Hemisphaerammina is completely absent. According to genetic data, Hemisphaerammina is branching at the base of the ‘clade F’ of monothalamous foraminifera, while the genus Crithionina is polyphyletic.
 Finally, some foraminifera reported further in this study, mostly the undetermined saccamminids ICEMON 3 and ICEMON 6 were poorly distinguishable from smaller, free individuals of F. islandica. We did not find enough specimens of these saccamminids to provide the full descriptive information and clearly outline the essential morphological differences, but none of them were genetically close to Flexammina.

description: We use chiral perturbation theory to investigate hadronic properties in strong electric and magnetic fields. A strong-field power counting is employed, and results for pions and nucleons are obtained using Schwinger's proper-time method. In the limit of weak fields, we accordingly recover the well known one-loop chiral perturbation theory results for the electric and magnetic polarizabilities of pions and nucleons. In strong constant fields, we extend the Gell-Mann-Oakes-Renner relation. For the case of electric fields, we find that non-perturbative effects result in hadron decay. For sufficiently strong magnetic fields, the chiral analysis confirms that the nucleon hierarchy becomes inverted giving rise to proton beta-decay. Properties of asymptotic expansions are explored by considering weak field limits. In the regime where the perturbative expansion breaks down, the first-order term gives the best agreement with the non perturbative result.

description: The main goal of coding theory is to devise efficient systems to exploit the full capacity of a communication channel, thus achieving an arbitrarily small error probability. Low Density Parity Check (LDPC) codes are a family of block codes--characterised by admitting a sparse parity check matrix--with good correction capabilities. In the present paper the orbits of subspaces of a finite projective space under the action of a Singer cycle are investigated.

description: Die folgende Arbeit setzt sich kritisch mit dem fehlenden strafprozessualen Zeugnisverweigerungsrecht nach § 53 StPO für Sozialarbeiter*innen sowie den daraus resultierenden Folgen auseinander. Sie zeigt auf, dass die Forderung nach einem ZVR für Sozialarbeitende seit Jahrzehnten besteht, in der Fachwelt als unstrittig gilt und durch eine Vielzahl von Argumenten gestützt wird. Dies wird insbesondere an zwei umfangreichen Rechtsgutachten deutlich, die in der Arbeit analysiert und verglichen werden. Dem gegenüber steht die Argumentation des Bundesverfassungsgerichts von 1972, die bis heute in Teilen immer noch als Grundlage gegen das ZVR für Sozialarbeitende dient sowie die neoliberale Ausrichtung des Staates, welche Strafverfolgung vor gelingende Hilfe zu stellen scheint. Diese Situation bedeutet für die Soziale Arbeit, sich nunmehr auf politischer Ebene organisieren zu müssen, um einen Gesetzgebungsprozess im Interesse ihrer Profession zu erwirken.

description: We present the first measurements of Charon's far-ultraviolet surface reflectance, obtained by the Alice spectrograph on New Horizons. We find no measurable flux shortward of 1650 A, and Charon's geometric albedo is $<0.019$ ($3σ$) at 1600 A. From 1650--1725 A Charon's geometric albedo increases to $0.166\pm0.068$, and remains nearly constant until 1850 A. As this spectral shape is characteristic of H$_2$O ice absorption, Charon is the first Kuiper belt object with a H$_2$O ice surface to be detected in the far-ultraviolet. Charon's geometric albedo is $\sim3.7$ times lower than Enceladus' at these wavelengths, but has a very similar spectral shape. We attribute this to similarities in their surface compositions, and the difference in absolute reflectivity to a high concentration or more-absorbing contaminants on Charon's surface. Finally, we find that Charon has different solar phase behavior in the FUV than Enceladus, Mimas, Tethys, and Dione, with a stronger opposition surge than Enceladus and a shallower decline at intermediate solar phase angles than any of these Saturnian satellites.

description: Realizing a large-scale quantum computer requires hardware platforms that can simultaneously achieve universality, scalability, and fault tolerance. As a viable pathway to meeting these requirements, quantum computation based on continuous-variable optical systems has recently gained more attention due to its unique advantages and approaches. This review introduces several topics of recent experimental and theoretical progress in the optical continuous-variable quantum computation that we believe are promising. In particular, we focus on scaling-up technologies enabled by time multiplexing, bandwidth broadening, and integrated optics, as well as hardware-efficient and robust bosonic quantum error correction schemes.

description: Two-dimensional ($p_{x}+ip_{y}$) superfluids/superconductors offer a playground for studying intriguing physics such as quantum teleportation, non-Abelian statistics, and topological quantum computation. Creating such a superfluid in cold fermionic atom optical traps using p-wave Feshbach resonance is turning out to be challenging. Here we propose a method to create a $p_{x}+ip_{y}$ superfluid directly from an s-wave interaction making use of a topological Berry phase, which can be artificially generated. We discuss ways to detect the spontaneous Hall mass current, which acts as a diagnostic for the chiral p-wave superfluid.

Membership and language use : an investigation into the internal sequential organization of naturally occurring stories from a social interaction perspective
Creators: name: Gardner, Holly
Publisher: name: University of British Columbia
Year: 2010

description: The research reported here constitutes an investigation into features of internal ordering of stories narrated in natural conversation. Following the work of Sacks, Schegloff and other sociological analysts of conversational structure, this report focuses on methodical ways in which utterances are interpretable by reference to, e.g., sequential placement. An existing literature on the social organization of the telling of jokes and stories suggests that slots designed for utterance-types can be analytically identified. The present study aims to show that there is an identifiable position, story closing, which provides for orderly expectations concerning the items that may be found in such a location. The report argues that there are two independently describeable organizations which structure naturally occuring stories: the course-of-action framework and an organization oriented to giving a grounding identity to the story's teller. The former is concerned with the series of connected, temporally unfolding events, marked by beginning and end, which the story proposes to represent by a sequence of utterances. In that story-tellers exhibit selectivity and coherence, it is evident that such stories are formulated from the point of view of the character that teller allocates to self within the narration. The latter organization provides for the story's recipients a "members adequate sociological explanation" of the teller's character's point of view. It does so by assigning to teller's character a social identity which is the locus of commonly known, socially organized motives and attitudes. The story closing is a sequential position that closes off the course-of-action from the teller's character's point of view. The expectation that such an item will fill that slot can be used by the story's recipients to decide among different possible interpretations of a story's last utterance.

description: 4U 1705-44 is one of the best studied type I X-ray burster and atoll sources. Since it covers a wide range in luminosity (from a few to 50 x 10^{36} erg s^{-1}) and shows clear spectral state transitions, it represents a good laboratory to test the accretion models proposed for atoll sources. We analysed the energy spectrum accumulated with BeppoSAX observations (43.5 ksec) in August 2000 when the source was in a soft spectral state. The continuum of the wide band energy spectrum is well described by the sum of a blackbody (kT_{bb}~0.56 keV) and a Comptonized component (seed-photon temperature kT_W~1 keV, electron temperature kT_e~2.7 keV, and optical depth ~11). A hard tail was detected at energies above ~25 keV. The latter can be modeled by a power law having a photon index ~2.9 which contributes ~11% of the total flux in the range 0.1-200 keV. A broad emission line, possibly from a relativistic accretion disk, models the feature in the Fe K line region of the spectrum. This is the first time that a high energy tail has been observed during a soft state of the source.

By studying the invariant mass spectra we confirm that decays of the $X(2370)$ into three pseudo-scalars are well described by an effective chiral Lagrangian. We extract the branching ratio of $J/ψ\to X(2370)γ$ and show that it is an order of magnitude larger compared to the glueball production rate predicted by lattice QCD. This indicates that $X(2370)$ is not likely to be a glueball candidate.

Trotzanfänglicher Erwartungen hat sich die Verbreitung von Smart-Home-Technik nicht so schnell entwickelt wie gedacht, jedoch ist es eine kontinuierliche Steigerung über die Jahre zu beobachten. Die Vielzahl an Literatur zu diesem Thema zeigt das anhaltende Interesse daran. Das vorgestellte Untersuchungskonzept bietet die Möglichkeit, die tatsächliche Alltagsnutzung von Smart-Home in Mietwohnungen zu erforschen und die Bedürfnisse der Mieter/innen besser zu verstehen. Die Einbindung der Bewohner/innen in den Gestaltungsprozess kann den Komfort und die Akzeptanz der Technologie steigern, unterstützt durch die Wahl des flexiblen KNX-Standards. Die Methode der Problemzentrierten Interviews, die in dieser Arbeit vorgestellt wird, ermöglicht eine nutzendennhahe Annäherung an das Thema Smart-Home und die Gewinnung von umfassenden Informationen, um den Umgang mit dieser Technik in Mietwohnungen zu verbessern. Diese Methode erfordert jedoch sorgfältige Vorbereitung und tiefes Verständnis vom Untersuchungsgegenstand. Die Zukunft der Smart-Home-Technik bleibt spannend. Die verbreitung wird voraussichtlich weiter steigen. Es bleibt jedoch abzuwarten, ob sie zur Standardausstattung in Mietwohnungen wird und wie sie unseren Alltag in Zukunft verändern wird.

description: This study demonstrates how the incremental 4D-Var data assimilation method can be applied efficiently preconditione d in an application to an oceanographic problem. The approach consists in performing a few iterations of the reduced-order 4D-Var prior to the incremental 4D-Var in the full space in order to achieve faster convergence. An application performed in the tropical Pacific Ocean, with assimilation of TAO temperature data, shows the method to be both feasible and efficient. It allows the global cost of the assimilation to be reduced by a factor of 2 without affecting the quality of the solution.

description: We report on the observation of five Feshbach resonances in collisions between ultracold $^7$Li and $^{87}$Rb atoms in the absolute ground state mixture where both species are in their $|f,m_f>=|1,1>$ hyperfine states. The resonances appear as trap losses for the $^7$Li cloud induced by inelastic heteronuclear three-body collisions. The magnetic field values where they occur are important quantities for an accurate determination of the interspecies interaction potentials. Results of coupled channels calculations based on the observed resonances are presented and refined potential parameters are given. A very broad Feshbach resonance centered around 649 G should allow for fine tuning of the interaction strength in future experiments.

Energy density balance during shock wave implosion in water

description: Analytical modeling of the evolution of cylindrical and spherical shock waves (shocks) during an implosion in water is presented for an intermediate range of convergence radii. Up to now this range is determined only in experiments observations as a range of implosion radii which are already far from the piston influence, but yet not described by well-known self-similar solutions. The model is based on an analysis of the change in pressure and kinetic energy density, as well as on the corresponding fluxes of internal and kinetic energy densities behind the shock front. It shows that the spatial evolution of the shock velocity strongly depends on the initial compression, the adiabatic index of water, and the geometry of convergence. The model also explains the transition to a rapid like self-similar increase in the shock velocity at only a certain radius of the shock that is observed in experiments. The dependence of the threshold radius, where the shock implosion follows the power law (quasi self-similarity), on the initial compression is determined. It is stated that in the entire range of the shock radii the internal and kinetic energy density fluxes are equal, which is in agreement with known experimental data.

Metastable supergravity vacua with F and D supersymmetry breaking

Subjects: subject: High Energy Physics - Theory (hep-th)

description: We study the conditions under which a generic supergravity model involving chiral and vector multiplets can admit viable metastable vacua with spontaneously broken supersymmetry and realistic cosmological constant. To do so, we impose that on the vacuum the scalar potential and all its first derivatives vanish, and derive a necessary condition for the matrix of its second derivatives to be positive definite. We study then the constraints set by the combination of the flatness condition needed for the tuning of the cosmological constant and the stability condition that is necessary to avoid unstable modes. We find that the existence of such a viable vacuum implies a condition involving the curvature tensor for the scalar geometry and the charge and mass matrices for the vector fields. Moreover, for given curvature, charges and masses satisfying this constraint, the vector of F and D auxiliary fields defining the Goldstino direction is constrained to lie within a certain domain. The effect of vector multiplets relative to chiral multiplets is maximal when the masses of the vector fields are comparable to the gravitino mass. When the masses are instead much larger or much smaller than the gravitino mass, the effect becomes small and translates into a correction to the effective curvature. We finally apply our results to some simple classes of examples, to illustrate their relevance.

description: In the arithmetic of function fields Drinfeld modules play the role that elliptic curves take on in the arithmetic of number fields. As higher dimensional generalizations of Drinfeld modules, and as the appropriate analogues of abelian varieties, G. Anderson introduced pure t-motives. In this article we study the arithmetic of the later. We investigate which pure t-motives are semisimple, that is, isogenous to direct sums of simple ones. We give examples for pure t-motives which are not semisimple. Over finite fields the semisimplicity is equivalent to the semisimplicity of the endomorphism algebra, but also this fails over infinite fields. Still over finite fields we study the endomorphism rings of pure t-motives and criteria for the existence of isogenies. We obtain answers which are similar to Tate's famous results for abelian varieties.

description: A multi-target detection system XAX, comprising concentric 10 ton targets of 136Xe and 129/131Xe, together with a geometrically similar or larger target of liquid Ar, is described. Each is configured as a two-phase scintillation/ionization TPC detector, enhanced by a full 4pi array of ultra-low radioactivity Quartz Photon Intensifying Detectors (QUPIDs) replacing the conventional photomultipliers for detection of scintillation light. It is shown that background levels in XAX can be reduced to the level required for dark matter particle (WIMP) mass measurement at a 10^-10 pb WIMP-nucleon cross section, with single-event sensitivity below 10^-11 pb. The use of multiple target elements allows for confirmation of the A^2 dependence of a coherent cross section, and the different Xe isotopes provide information on the spin-dependence of the dark matter interaction. The event rates observed by Xe and Ar would modulate annually with opposite phases from each other for WIMP mass >~100 GeV/c^2. The large target mass of 136Xe and high degree of background reduction allow neutrinoless double beta decay to be observed with lifetimes of 10^27-10^28 years, corresponding to the Majorana neutrino mass range 0.01-0.1 eV, the most likely range from observed neutrino mass differences. The use of a 136Xe-depleted 129/131Xe target will also allow measurement of the pp solar neutrino spectrum to a precision of 1-2%.

description: This paper proposes a novel technique for the design of miniaturized waveguide filters based on locally resonant metamaterials (LRMs). We implement ultra-small metamaterial filters (Meta-filters) by exploiting a subwavelength (sub-lambda guiding mechanism in evanescent hollow waveguides, which are loaded by small resonators. In particular, we use composite pin-pipe waveguides (CPPWs) built from a hollow metallic pipe loaded by a set of resonant pins, which are spaced by deep subwavelength distances. We demonstrate that in such structures, multiple resonant scattering nucleates a sub-lambda mode with a customizable bandwidth below the induced hybridization bandgap (HBG) of the LRM. The sub-lambda guided mode and the HBG, respectively, induce pass- and rejection- bands in a finite-length CPPW, creating a filter whose main properties are largely decoupled from the specific arrangement of the resonant inclusions. To guarantee compatibility with existing technologies, we propose a unique subwavelength method to match the small CPPW filters to standard waveguide interfaces, which we call a meta-port. Finally, we build and test a family of low- and high-order ultra-compact aluminum CPPW filters in the Ku-band (10-18GHz). Our measurements demonstrate the customizability of the bandwidth and the robustness of the passband against geometrical scaling. The 3D-printed prototypes, which are one order of magnitude smaller and lighter than traditional filters and are also compatible with standard waveguide interfaces, may find applications in future satellite systems and 5G infrastructures.

description: The commonly applied self-similar solution of the problem of the converging shock wave (shock) evolution with constant compression of the medium behind the shock front results in an unlimited increase of the medium velocity in the vicinity of the implosion. In this paper, the convergence of cylindrical shocks in water is analyzed using the mass conservation law, when the water compression behind the shock front is a variable. The model predicts a finite range of radii, which depends on the adiabatic index of water and where the increase in pressure exceeds the sum of the change of the kinetic and internal energy densities behind the shock front. In this range of radii only the finite increase of the shock and water flow velocities is realized.

Survival and growth curve analyses applied to a barnacle data set
Creators: name: Freund, Vivien
Publisher: name: University of British Columbia
Year: 2010

description: A data set relating to the survival and growth of barnacles is examined. Survival distributions are compared by means of three nonparametric tests. The exponential model is then fitted for the survival distributions and a random effects model is developed for the slope. Polynomial growth curves are fitted and various hypotheses relating to the parameters are tested using firstly the model of Pothoff and Roy and secondly the model of Rao. Owing to the nature of the growth data, which is not longitudinal, this presents various statistical problems which are discussed.

description: AIMS: To study the structure of nearby (< 500 pc) dense starless and star-forming cores with the particular goal to identify and understand evolutionary trends in core properties, and to explore the nature of Very Low Luminosity Objects (< 0.1 L_sun; VeLLOs). METHODS: Using the MAMBO bolometer array, we create maps unusually sensitive to faint (few mJy per beam) extended (approx. 5 arcmin) thermal dust continuum emission at 1.2 mm wavelength. Complementary information on embedded stars is obtained from Spitzer, IRAS, and 2MASS. RESULTS: Our maps are very rich in structure, and we characterize extended emission features (``subcores'') and compact intensity peaks in our data separately to pay attention to this complexity. We derive, e.g., sizes, masses, and aspect ratios for the subcores, as well as column densities and related properties for the peaks. Combination with archival infrared data then enables the derivation of bolometric luminosities and temperatures, as well as envelope masses, for the young embedded stars. CONCLUSIONS: (abridged) Starless and star-forming cores occupy the same parameter space in many core properties; a picture of dense core evolution in which any dense core begins to actively form stars once it exceeds some fixed limit in, e.g., mass, density, or both, is inconsistent with our data. Comparison of various evolutionary indicators for young stellar objects in our sample (e.g., bolometric temperatures) reveals inconsistencies between some of them, possibly suggesting a revision of some of these indicators.

description: Energy and angular dependence of double differential cross sections d$^2σ$/d$Ω$dE was measured for reactions induced by 2.5 GeV protons on Au target with isotopic identification of light products (H, He, Li, Be, and B) and with elemental identification of heavier intermediate mass fragments (C, N, O, F, Ne, Na, Mg, and Al). It was found that two different reaction mechanisms give comparable contributions to the cross sections. The intranuclear cascade of nucleon-nucleon collisions followed by evaporation from an equilibrated residuum describes low energy part of the energy distributions whereas another reaction mechanism is responsible for high energy part of the spectra of composite particles. Phenomenological model description of the differential cross sections by isotropic emission from two moving sources led to a very good description of all measured data. Values of the extracted parameters of the emitting sources are compatible with the hypothesis claiming that the high energy particles emerge from pre-equilibrium processes consisting in a breakup of the target into three groups of nucleons; small, fast and hot fireball of $\sim$ 8 nucleons, and two larger, excited prefragments, which emits the light charged particles and intermediate mass fragments. The smaller of them contains $\sim$ 20 nucleons and moves with velocity larger than the CM velocity of the proton projectile and the target. The heavier prefragment behaves similarly as the heavy residuum of the intranuclear cascade of nucleon-nucleon collisions. %The mass and charge dependence of the total production cross %sections was extracted from the above analysis for all observed %reaction products. This dependence follows the power low behavior %(A$^{-τ}$ or Z$^{-τ}$).

description: The upcoming X-ray missions based on the microcalorimeter technology require exquisite precision in spectral simulation codes in order to match the unprecedented spectral resolution. In this work, we improve the fluorescence K$α$ energies for Si II-XI and S II-XIII in the code Cloudy. In particular, we provide here a patch to update the Cloudy fluorescence energy table, originally based on Kaastra & Mewe (1993), with the laboratory energies measured by Hell et al. (2016). The new Cloudy simulations were used to model the Chandra/HETG spectra of the High Mass X-ray Binary Vela X-1 previously presented in Amato et al. (2021), showing a remarkable agreement and a dramatic improvement with respect to the current release version of Cloudy (C17.02).

Remittance bards : the places, tribes, and dialects of Patrick White and Malcolm Lowry
Creators: name: Williams, Clifton Mark
Publisher: name: University of British Columbia
Year: 2010

description: This thesis traces the efforts of Patrick White and Malcolm Lowry between the years 1933 and 1957 to "purify the dialect of the tribe." As young writers in the England of the Thirties both felt the language of the English middle class, the pre-dominant dialect of English fiction, to be exhausted. Some time in the Forties, both chose to live and write in isolated places where they believed there to be English dialects which possessed a vigour and a contact with reality absent in the England they had abandoned. The texture and structure of their subsequent writing demonstrate the effects of this choice of locales. My introductory chapter surveys the concern of both novelists, up to the end of the Fifties, with language, class, and place, and addresses the biographical facts relevant to these concerns. This discussion establishes the formal, linguistic, and ideological parameters of my approach to these novelists. The body of the thesis is divided into two sections: the first deals with the period up to 1941, the second with the post-war period. Part A, chapter I addresses the cultural background and the ideological confusion of young middle-class writers in England during the Thirties. The following three chapters set the early novels of both writers in this context. Part B begins by establishing the post-war literary milieu in England from which the fiction of White and Lowry offers a sharp break. The following five chapters consider the continuing influence of Thirties dilemmas on their approach to form and the use of language, the attempts of both writers to find formal means adequate to their readings of the contemporary world, and their progressive break with literary realism. The conclusion evaluates the literary results of these struggles with language: in particular, the degree to which a creative use of dialect has extended the range of the English novel during a period characterized in England by caution and retrenchment.
Suppression of forward dilepton production from an anisotropic quark-gluon plasma

description: We calculate the rapidity dependence of leading-order medium dilepton yields resulting from a quark-gluon plasma which has a local time-dependent anisotropy in momentum space. We present a phenomenological model which includes temporal evolution of the plasma anisotropy parameter, xi, and the hard momentum scale, p_hard. Our model interpolates between 1+1 dimensional collisionally-broadened expansion at early times and 1+1 dimensional ideal hydrodynamic expansion at late times. Using our model, we find that at LHC energies, forward high-energy medium dilepton production would be suppressed by up to a factor of 3 if one assumes an isotropization/thermalization time of 2 fm/c. Therefore, it may be possible to use forward dilepton yields to experimentally determine the time of onset of locally isotropic hydrodynamic expansion of the quark-gluon plasma as produced in ultrarelativistic heavy-ion collisions.
