Sediment movement in a sub-alpine basin in the Coast Mountains of British Columbia
Creators: name: Jones, Penelope Sarah Ann
Publisher: name: University of British Columbia
Year: 2010

description: Sediment transfers in a small alpine valley were measured during the summer of 1981. The sediment budget concept was used to generate three hypotheses which guided the study. Data were collected at 20 sites using Gerlach troughs, splash troughs and bulk samplers. Spatial integration of site data established that wind was overall the most important component of the sediment budget. Eolian material included both direct deposition during the summer months and mineral material stored in the winter snowpack. Measured rates of deposition matched accumulation rates calculated from the soil profile and mineralogy suggested a regional source for windblown material. Animals (marmots) are the main agents of sediment transfer on talus sites but as their influence is spatially limited, they are less important than wind over the whole basin area. Overland flow and rainsplash perform some sediment transfer on unvegetated areas of fine debris. The same sites support needle ice which contributes little to the total sediment budget. This ranking is tentative as the field season had late snowmelt, early fall snow accumulation and an exceptionally warm, dry August. The stratified, random, replicated sampling scheme employed in this study was inefficient as many sites straddled two vegetation strata. Use of a plane table map rather than aerial photographs for a base map should improve efficiency.

description: We report a high-resolution resonant inelastic x-ray scattering study of La2CuO4. A number of spectral features are identified that were not clearly visible in earlier lower-resolution data. The momentum dependence of the spectral weight and the dispersion of the lowest energy excitation across the insulating gap have been measured in detail. The temperature dependence of the spectral features was also examined. The observed charge transfer edge shift, along with the low dispersion of the first charge transfer excitation are attributed to the lattice motion being coupled to the electronic system. In addition, we observe a dispersionless feature at 1.8 eV, which is associated with a d-d crystal field excitation.

description: Infolge der Gräueltaten durch die Nationalsozialisten wurde in Österreich unmittelbar nach Kriegsende das Verbotsgesetz beschlossen, das jegliche Betätigung im nationalsozialistischen Sinne untersagt. Das Gesetz wurde inzwischen mehrfach novelliert. Der vorliegende Beitrag behandelt ausgewählte Aspekte des Verbotsgesetzes sowie überblicksmäßig die Anzeige- und Verurteilungspraxis im Zeitverlauf. Weiters wird das Projekt „3g VerbotsGesetz“ vorgestellt, das es für junge Menschen ohne gefestigtes nationalsozialistisch-ideologisches Fundament durch einen Besuch der KZ-Gedenkstätte Mauthausen eine Auseinandersetzung mit dem Ort und seiner Geschichte ermöglicht (4.). Schließlich werden an einem ausgewählten Fallbeispiel verfahrensrechtliche Aspekte einer alternativen Verfahrenserledigung von Verstößen gegen das Verbotsgesetz diskutiert.

description: Der Beitrag handelt von „Krimmigration“, der Analyse des Zusammenspiels zwischen straf- und migrationsrechtlicher Kontrolle zulasten der Betroffenen. Er lehnt sich dafür an das für das US-amerikanische Recht beschriebene Phänomen des „Crimmigration law“ an und beschreibt anhand von Beispielen Entsprechendes im deutschen Recht. Dabei wird auf das Migrationsstrafrecht und Polizeikontrollen in Verbindung damit eingegangen. Es wird die Anwendung typischerweise aus dem Strafrecht bekannter Institutionen und Interventionen (z.B. gefängnisartige Haft, strafprozessuale Maßnahmen) im Migrationsrecht betrachtet. Besonderes Augenmerk liegt auf aufenthaltsrechtlichen Interventionen zu strafrechtlichen Zwecken und dem dadurch entstehenden abweichenden Straftatverdachtfolgenrecht für Nichtdeutsche im Gegensatz zu dem für deutsche Staatsangehörige. Es werden strafähnliche Maßnahmen im Migrationsrecht beschrieben, aber auch wie sich die migrationsrechtliche Logik auf den Straf- und Maßregelvollzug auswirkt. Es folgt das Resümee, wonach straf- und migrationsrechtliche Kontrolle im deutschen Recht miteinander verpuzzelt sind (statt wie in der US-amerikanischen Debatte verschmolzen). Die Eingriffskompetenzen und -instrumentarien aus beiden Bereichen greifen dabei gezielt ineinander.

description: We present the results of our QCD analysis for nonsinglet unpolarized quark distributions and structure function $F_2(x,Q^2)$. New parameterizations are derived for the nonsinglet quark distributions for the kinematic wide range of $x$ and $Q^2$. The analysis is based on the Jacobi polynomials expansion of the structure function. The higher twist contributions of proton and deuteron structure function are obtained in the large $x$ region. Our calculations for nonsinglet unpolarized quark distribution functions based on the Jacobi polynomials method are in good agreement with the other theoretical models. The values of $Λ_{QCD}$ and $α_s(M_z^2)$ are determined.

Profitability of Farms Converting to Organic Farming in Germany

description: The Institute of Farm Economics of the FAL monitors 107 farms which have started conversion to organic farming in the crop year 1990/91. The objective is to identify the economic impacts of conversion to organic farming on different farm types. After three years of organic farming, a wide variety of changes in the farms can be observed. Because organic farming prohibits the use of chemical inputs, crop rotation and the cropping of legumes gain more importance. Furthermore, the land use system depends strongly on the marketing possibilities of organically grown products. Livestock numbers show a declining trend. On the other hand, labor requirements are increasing. In crop production, the yields decrease strongly. At this point in time, higher prices can only be realized for plant products. Overheads increased only slightly during the study period. The conversion to organic farming has led to positive income effects for the majority of farms. However, the profitability of organic farming depends largely on the extensification premium and the marketing possibilities for organic products.

Inflationary quantum dynamics and backreaction using a classical-quantum correspondence

Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)

description: We study inflationary dynamics using a recently introduced classical-quantum correspondence for investigating the backreaction of a quantum mechanical degree of freedom to a classical background. Using specifically a coupled Einstein-Klein-Gordon system, an approximation that holds well during the very early inflationary era when modes are very deep inside the Hubble horizon, we show that the backreaction of a mode of the quantum field will renormalize the Hubble parameter only if the mode's wavelength is longer than some threshold Planckian length scale. Otherwise, the mode will destabilize the inflationary era. We also present an approximate analytical solution that supports the existence of such short-wavelength threshold and compare the results of the classical-quantum correspondence with the traditional perturbative-iterative method in semiclassical gravity.

description: We use HAWK-I, the recently-commissioned near-IR imager on Yepun (VLT-UT4), to obtain wide-field, high-resolution images of the X-ray luminous galaxy cluster XMMU J2235.3-2557 in the J and Ks bands, and we use these images to build a colour-magnitude diagram of cluster galaxies. Galaxies in the core of the cluster form a tight red sequence with a mean J-Ks colour of 1.9 (Vega system). The intrinsic scatter in the colour of galaxies that lie on the red sequence is similar to that measured for galaxies on the red sequence of the Coma cluster. The slope and location of the red sequence can be modelled by passively evolving the red sequence of the Coma cluster backwards in time. Using simple stellar population (SSP) models, we find that galaxies in the core of XMMU J2235.3-2557 are, even at z=1.39, already 3 Gyr old, corresponding to a formation redshift of z ~ 4. Outside the core, the intrinsic scatter and the fraction of galaxies actively forming stars increase substantially. Using SSP models, we find that most of these galaxies will join the red sequence within 1.5 Gyr. The contrast between galaxies in the cluster core and galaxies in the cluster outskirts indicates that the red sequence of XMMU J2235.3-2557 is being built from the dense cluster core outwards.

The construction of spinfoam amplitudes uses the state-integral model of PSL(2,$\mathbb{C}$) Chern-Simons theory and the implementation of simplicity constraint. The formulation has 2 key features: (1) spinfoam amplitudes are all finite, and (2) With suitable boundary data, the semiclassical asymptotics of the vertex amplitude has two oscillatory terms, with phase plus or minus the 4-dimensional Lorentzian Regge action with cosmological constant for the constant curvature 4-simplex.

description: Graphene has shown great application potentials as the host material for next generation electronic devices. However, despite its intriguing properties, one of the biggest hurdles for graphene to be useful as an electronic material is its lacking of an energy gap in the electronic spectra. This, for example, prevents the use of graphene in making transistors. Although several proposals have been made to open a gap in graphene's electronic spectra, they all require complex engineering of the graphene layer. Here we show that when graphene is epitaxially grown on the SiC substrate, a gap of ~ 0.26 is produced. This gap decreases as the sample thickness increases and eventually approaches zero when the number of layers exceeds four. We propose that the origin of this gap is the breaking of sublattice symmetry owing to the graphene-substrate interaction. We believe our results highlight a promising direction for band gap engineering of graphene.

Subjects: Farm Management

description: This paper presents the background, development, content, successes, short comings, and possible sequel of a national farm management research conference recently held in the United States of America. The paper offers two benefits to the international farm management community. First, is an awareness of the conference and of the availability of conference proceedings. Second, is provision of a model that may be used and improved upon by farm management specialists in other countries who may wish to organise a similar conference. The conference included ten presented papers, discussions of those papers, a panel of two agricultural industry leaders, group discussions, and concluding comments. Possible improvements on a second conference include involvement of professional farm managers, more small group discussion, efforts to reach consensus on specific future priorities and agenda, and scheduled time for participants to specify and share their individual future priorities and agenda.

description: A pilot survey conducted at the Lookout Observatory has confirmed seven faint (V ~ 13 to 17) variables in the region of Kepler-76b that were recently discovered by the Asteroid Terrestrial-Impact Last Alert System (ATLAS). The ATLAS survey identified 315,000 probably variables within its wide-field survey in 2018. The faintness (down to r ~ 18) and small amplitudes (down to 0.02 mag) included in these candidates makes external validation difficult. Our confirmation of seven such variable stars gives credibility to the ATLAS list. Further, the agreement between various surveys and LO data validates the use of our new survey for variable star and exoplanet research.

description: We report magnetization experiments in two magnetically isolated ferromagnetic nanotubes of perovskite La$_{0.67}$Ca$_{0.33}$MnO$_3$. The results show that the magnetic anisotropy is determined by the sample shape although the coercive field is reduced by incoherent magnetization reversal modes. The temperature dependence of the magnetization reveals that the magnetic behavior is dominated by grain surface properties. These measurements were acquired using a Silicon micro-mechanical oscillator working in its resonant mode. The sensitivity was enough to measure the magnetic properties of these two samples with a mass lower than 14 picograms and to obtain for the first time the magnetization loop for one isolated nanotube.

description: We present a study for a sample of galaxies with active nuclei to characterize the main type of PAH molecules present in these objects and the local physical conditions of their irradiating sources, as well as the characteristics of the residing ionized gas, by combining optical and infrared data. Photoionization models were built with the {\sc CLOUDY} code to reproduce optical emission line ratios in combination with PAH intensity ratios. We find that the species containing 10 $-$ 82 carbon atoms are the most abundant in the sample. We suggest that family of species with only two or three fused rings of and a nitrogen hanging, such as small aromatic amides are important targets worthy of consideration in future experimental/theoretical as well as observational studies. We find that the AGN photoionization models reproduce most of the observational data in the log (6.2/11.3) versus log ([\ion{N}{ii}]$λ$6584/H$α$) diagram with the optical to X-ray spectral index of $α_{\rm ox}=-1.4$. The flux of small PAH, as well as the flux of ionized PAHs and PANH, decrease as the logarithm of the ionization parameter (log $U$) increases. The 6.2/11.3 PAH intensity ratio presents anti correlation between the oxygen abundance and log $U$, in the sense that the 6.2/11.3 ratio decreases as the oxygen abundance and log $U$ increases. Finally, we found that the ionization degree of PAH species increases with the decreasing of the 11.3/7.7 ratio and the log U, in agreement with the models proposed by Draine \& Li.

Im Mittelpunkt steht dabei die Fragestellung, wie sich die psychosoziale Unterstützungsarbeit im Zusammenspiel aller Akteure in der Akutphase der ersten zwei Tage im Einsatz am Breitscheidplatz gestaltet hat. Dabei werden die psychosozialen Bedürfnisse von Betroffenen bei Terroranschlägen mit Bezug zur internationalen Forschungsliteratur aus kriminologischer und psychologischer Perspektive herausgearbeitet und deren Bearbeitung durch die Netzwerke der psychosozialen Notfallversorgung am Beispiel des Einsatzes am Berliner Weihnachtsmarkt untersucht. Im Ergebnis lässt sich feststellen, dass insbesondere unmittelbare Bedürfnisse der Betroffenen, wie Einordnung und Orientierung, Sicherheit und Emotionsausdruck von den interviewten PSNV-Akteuren aufgegriffen wurden, während mittelbare Bedürfnisse kaum adressiert wurden. Für die weitere Entwicklung einer funktionalen psychosozialen Notfallversorgung ist daher die verstärkte Vernetzung der zivilgesellschaftlich verankerten Hilfsnetzwerke der PSNV sowie die Fortentwicklung der methodischen Handlungskonzepte für komplexe Schadenslagen anzuraten.

description: An analysis of four new production systems for sows and weaners with an improved animal welfare and reduced capital shows, that the new production systems are competitive to the traditional systems with fixed sows. The most significant difference between the production systems is the rate of return on the total capital invested, where the outdoor systems have close to a 24 percentage rate of return, which is roughly five to eight percentage points higher than for the other systems. The low capital input for outdoor systems (only one third corresponding to traditional inddoor systems) and a very simple technical set up makes it possible for the farmer to react on price fluctuations, extreme weather conditions and other unexpected conditions. It is also easier to practise gradual expansion. The analysis has shown that profitable and competitive systems exist which meet future requirements of animal welfare.

description: Neurofeedback games are an effective and playful approach to enhance certain social and attentional capabilities in children with autism, which are promising to become widely accessible along with the commercialization of mobile EEG modules. However, little industry-based experiences are shared, regarding how to better design neurofeedback games to fine-tune their playability and user experiences for autistic children. In this paper, we review the experiences we gained from industry practice, in which a series of mobile EEG neurofeedback games have been developed for preschool autistic children. We briefly describe our design and development in a one-year collaboration with a special education center involving a group of stakeholders: children with autism and their caregivers and parents. We then summarize four concrete implications we learnt concerning the design of game characters, game narratives, as well as gameplay elements, which aim to support future work in creating better neurofeedback games for preschool children with autism.

description: Innerhalb der rechtsextremen als auch der salafistisch jihadistischen Szene spielt Musik einen wichtigen integrativen und radikalisierenden Faktor. Musik wird zur Verbreitung der eigenen Propaganda genutzt, spezifische Ideologeme werden mit Musik unterlegt und als „Schulhof-CD“ oder in Form von Nashids über das Internet und die Sozialen Medien verbreitet und strategisch zur Gewinnung von neuen Mitgliedern genutzt. Ziel rechtsextremer Musik, die mittlerweile in allen musikalischen Genre aufzufinden ist, als auch der salafistisch jihadistischen Nashids, ist unter anderem die Inspiration der Jugend, das weltweite Erreichen von Sympathisanten, sowie die Verbreitung ihrer absolutistischen Weltanschauung mit Hilfe von vermeintlich objektiven Schilderungen von negativen Alltagserfahrungen, von Unterdrückung und der Notwendigkeit Widerstand zu leisten. Dabei sind die Lieder meist verknüpft mit gewaltverherrlichenden Inhalten, die auf einen fatalen Realismus abzielen und in Verbindung mit Videos die vermeintlich empfundene Notwendigkeit verdeutlichen, sich verteidigen zu müssen. Innerhalb dieses Beitrags werden die Inhalte von ausgewählten rechtsextremen als auch salafistisch jihadistischen Liedern, die innerhalb der einzelnen Szenen zirkulieren, in den Fokus genommen. Die Analyse der Inhalte basiert dabei auf einer Methodentriangulation (sequenzieller Textanalysen) und soll in einem abschließenden Schritt die Unterschiede aber auch die vergleichbaren Elemente der Ideologien herausarbeiten. Ziel dieses Beitrages ist es, die Musik extremistischer Gruppierungen auf ihren Inhalt und ihre mögliche Wirkung zu untersuchen.

The single crystals of RAg$_2$Ge$_2$ (R = Pr, Nd and Sm) were grown by self-flux method using Ag:Ge binary alloy as flux. From the magnetic studies on single crystalline samples we have found that PrAg$_2$Ge$_2$ and NdAg$_2$Ge$_2$ order antiferromagnetically at 12 K and 2 K respectively, thus corroborating the earlier polycrystalline results. SmAg$_2$Ge$_2$ also orders antiferromagnetically at 9.2 K. The magnetic susceptibility and magnetization show a large anisotropy and the easy axis of magnetization for PrAg$_2$Ge$_2$ and NdAg$_2$Ge$_2$ is along the [100] direction where as it changes to [001] direction for SmAg$_2$Ge$_2$. Two metamagnetic transitions were observed in NdAg$_2$Ge$_2$ at $H_{\rm m1}$ = 1.25 T and $H_{\rm m2}$ =3.56 T for the field parallel to [100] direction where as the magnetization along [001] direction was linear indicating the hard axis of magnetization.

description: Die relative Unauffälligkeit des Täters vor der Tat, die häufig bei hochexpressiver Gewalt (z.B. sog. Amokläufen) imponiert, stellt für die Kriminologie eine gewisse Herausforderung dar. Am Empirismus orientierte Modelle zum Verständnis solcher Taten greifen hier zu kurz, wie auch lediglich beschreibende und (z.B. im Hinblick auf das Konzept der Persönlichkeit) kulturell kontingente Psychopathologiekonzepte, da die verfügbaren Daten oft nicht ausreichen und die Gefahr der Reifikation besteht. Daher wird hier alternativ ein konfigurativer Ansatz skizziert, der Erkenntnisse aus der Soziologie und der Psychoanalyse bzw. kulturelle und individualpsychologische Aspekte konvergiert sowie ihre immanente Logik herausstellt. Als zentral für derartige Taten werden nichtintegrierte aggressive Impulse angesehen, sowie damit in Verbindung ein primärer, globaler Modus der Identifizierung, der einen kompulsiven Charakter annimmt und die Fähigkeit zur eigenständigen Affektregulierung beeinträchtigt. Auf diese Weise können Vortaten handlungsbestimmend werden. Als Ausgangspunkt einer solchen Entwicklung werden frühe, vor allem bindungsbezogene Traumata postuliert, die in der Folge zu erheblichen Retraumatisierungen in sozialen Kontexten geführt haben.
A comprehensive investigation of data dictionaries
Creators: name: Diersch, Thomas Karl Julius
Publisher: name: University of British Columbia
Year: 2010

description: This thesis reviews data dictionary systems, approaching the subject from four directions. First, the contents of dictionaries are examined. Second, the users and their interaction and use of the data dictionary are reviewed. Third, some popular commercial data dictionary packages are reviewed. Finally, data dictionaries are examined as a package to be implemented by a data processing department. Data dictionary entities can be grouped into four classes, each adding to the information stored by the preceeding layer. They are, the data dictionary which stores data entity data, data directories, which store processing entity data and process-data relationships, data resource dictionaries, which store data about processing environment entities such as hardware, and the metadata dictionary which stores data about conceptual entities such as events and functions. Using this structure, each class of dictionary is examined to identify the entities and their attributes. Users are examined in the following groups: the database administrator, systems analysts, programmers, the data processing operations department, and the user group. Five commercially available dictionaries are examined in detail, DATAMANAGER, DB/DC Data Dictionary, Data Catalogue 2, UCC-10, and IDD. In addition, the thesis examines two dictionaries in overview, highlighting their advanced thinking. ICL DDS, which allows the user to model both implementation and conceptual views of data, and CINCOM's DCS which includes the dictionary in a package containing a screen design aid, a programmer workstation, and security system all integrated with the dictionary. The data dictionary is examined from a system application view point addressing the questions to which any application is subjected when evaluated. Identifying the need for a data dictionary, three areas are examined. First the control of data as an organizational resource, second the use of system development methodologies and third, the management of change in data processing systems. The ability of the data dictionary to support a data processing environment which uses conventional file structures, a simple database or a complex environment with multiple databases, or distributed processing is addressed. Software selection criteria are examined, defining the dictionary content, and utilities which should be investigated, and criteria for environment such as data processing hardware and software, user-vendor relationships and cost and maintenance are proposed. Finally we propose some events in the data processing life cycle which may assist in the successful implementation of a data dictionary. Implementation in a complex environment where no other project proposed is critical, or before a major database management system conversion may be warranted. Or implementation may be undertaken before a large systems project, or as part of a data processing standards project.
Fluctuations of the Casimir-Polder force between an atom and a conducting wall

description: We consider the quantum fluctuations of the Casimir-Polder force between a neutral atom and a perfectly conducting wall in the ground state of the system. In order to obtain the atom-wall force fluctuation we first define an operator directly associated to the force experienced by the atom considered as a polarizable body in an electromagnetic field, and we use a time-averaged force operator in order to avoid ultraviolet divergences appearing in the fluctuation of the force. This time-averaged force operator takes into account that any measurement involves a finite time. We also calculate the Casimir-Polder force fluctuation for an atom between two conducting walls. Experimental observability of these Casimir-Polder force fluctuations is also discussed, as well as the dependence of the relative force fluctuation on the duration of the measurement.

In Ha Bik Chuen’s ‘Thinking Studio’ Beyond the Archive Reflections on the Exhibition Non-history (2020) at the Hong Kong Fringe Club

description: The fever for archives benumbs. This essay explores the daze through the example of the Ha Bik Chuen Archive, a documentation, conservation and digitization project at Hong Kong’s Asia Art Archive (2014-ongoing). Working with the distinction between Aby Warburg’s concepts of Zwischenraum (intermediate space) and Denkraum (space of thinking) theorized by philologist Victoria Cirlot, it stakes a claim for differentiating between the ‘archive’ and what Hong Kong artist Ha Bik Chuen called his 思考工作室 (Cantonese for ’thinking studio’ or ‘studio of thoughts’). Ha used the term ‘thinking studio’ to describe the aggregation of materials that, over five decades, came together in his home in To Kwa Wan, Kowloon. AAA’s work with Ha’s ‘thinking studio’ transformed it, not only by making it public, but by presenting it and circulating it as a new object called “archive”. In describing the “industrialization of digital technology”, philosopher Yuk Hui has written, “we are all archivists, since we have to be. We don’t have a choice”. What is lost when all aggregations of materials are subsumed under the ‘archive’? The exhibition, Non-history (2020) curated by Vennes Cheng at the Hong Kong Fringe Club, showed items from Ha’s ‘thinking studio’ alongside works by artists Morgan Wong and Lee Kai Chung; it also suggested connections between the ‘thinking studio’ and Aby Warburg’s practice of gathering images and creating critical constellations, as in the famous Bilderatlas Mnemosyne (Mnemosyne Atlas, 1924-1929). By making an explicit connection – not made in the exhibition – between Ha’s “thinking space” and the theorization of Warburg’s Denkraum, the essay opens a passage back to the ‘thinking studio’ that, by venturing through the critical interventions of artists Wong and Lee, reveals other sensibilities for smallness – other temporalities, other narratives, other technologies and other phantoms – calling to be scavenged from under the voracious ‘archive’.
Symplectic symmetries of 4-manifolds

description: A study of symplectic actions of a finite group $G$ on smooth 4-manifolds is initiated. The central new idea is the use of $G$-equivariant Seiberg-Witten-Taubes theory in studying the structure of the fixed-point set of these symmetries. The main result in this paper is a complete description of the fixed-point set structure (and the action around it) of a symplectic cyclic action of prime order on a minimal symplectic 4-manifold with $c_1^2=0$. Comparison of this result with the case of locally linear topological actions is made. As an application of these considerations, the triviality of many such actions on a large class of 4-manifolds is established. In particular, we show the triviality of homologically trivial symplectic symmetries of a $K3$ surface (in analogy with holomorphic automorphisms). Various examples and comments illustrating our considerations are also included.

description: Professor Jayanta Kumar Ghosh has contributed massively to various areas of Statistics over the last five decades. Here, we survey some of his most important contributions. In roughly chronological order, we discuss his major results in the areas of sequential analysis, foundations, asymptotics, and Bayesian inference. It is seen that he progressed from thinking about data points, to thinking about data summarization, to the limiting cases of data summarization in as they relate to parameter estimation, and then to more general aspects of modeling including prior and model selection.

HST Observations of Chromospheres in Metal Deficient Field Giants

description: HST high resolution spectra of metal-deficient field giants more than double the stars in previous studies, span about 3 magnitudes on the red giant branch, and sample an abundance range [Fe/H]= -1 to -3. These stars, in spite of their age and low metallicity, possess chromospheric fluxes of Mg II (2800 Angstrom) that are within a factor of 4 of Population I stars, and give signs of a dependence on the metal abundance at the lowest metallicities. The Mg II k-line widths depend on luminosity and correlate with metallicity. Line profile asymmetries reveal outflows that occur at lower luminosities (M_V = -0.8) than detected in Ca K and H-alpha lines in metal-poor giants, suggesting mass outflow occurs over a larger span of the red giant branch than previously thought, and confirming that the Mg II lines are good wind diagnostics. These results do not support a magnetically dominated chromosphere, but appear more consistent with some sort of hydrodynamic, or acoustic heating of the outer atmospheres.

description: We systematically study the phases of generic toric singularities, using methods initiated in hep-th/0612046. These correspond to Gauged Linear Sigma Models with arbitrary charges. We show that complete information about generic $U(1)^r$ GLSMs can be obtained by studying the GLSM Lagrangian, appropriately modified in the different phases of the theory. This can be used to study the different phases of $L^{a,b,c}$ spaces and their non-supersymmetric counterparts.

description: We theoretically evaluate changes in the magnetic potential arising from the magnetic field near superconducting thin films. An example of an atom chip based on a three-wire configuration has been simulated in the superconducting and the normal conducting state. Inhomogeneous current densities within the superconducting wires were calculated using an energy-minimization routine based on the London theory. The Meissner effect causes changes to both trap position and oscillation frequencies at short distances from the superconducting surface. Superconducting wires produce much shallower micro traps than normal conducting wires. The results presented in this paper demonstrate the importance of taking the Meissner effect into account when designing and carrying out experiments on magnetically trapped neutral atoms near superconducting surfaces.

description: We present the calculation of the Wt single-top production channel to next-to-leading order in QCD, interfaced with parton showers within the MC@NLO formalism. This channel provides a complementary way of investigating the properties of the Wtb vertex, with respect to the s- and t-channels. We pay special attention to the separation of this process from top quark pair production.
