description: We simulate the central reactions of $^{20}$Ne+$^{20}$Ne, $^{40}$Ar+$^{45}$Sc, $^{58}$Ni+$^{58}$Ni, $^{86}$Kr+$^{93}$Nb, $^{129}$Xe+$^{118}$Sn, $^{86}$Kr+$^{197}$Au, and $^{197}$Au+$^{197}$Au at different incident energies for different equations of state, different binary cross sections and different widths of Gaussians. A rise-and-fall behavior of the multiplicity of intermediate mass fragments (IMFs) is observed. The system size dependence of peak center-of-mass energy E$_{c.m.} ^{max}$ and peak IMF multiplicity $^{max}$ is also studied, where it is observed that E$_{c.m.}^{max}$ follows a linear behavior and $^{max}$ shows a power-law dependence. A comparison between two clusterization methods, the minimum spanning tree and the minimum spanning tree method with binding energy check (MSTB), is also made. We find that the MSTB method reduces the $^{max}$, especially in heavy systems. The power-law dependence is also observed for fragments of different sizes at E$_{c.m.} ^{max}$ and the power-law parameter $τ$ is found to be close to unity in all cases except A$^{max}$.

Culture and identity : language use in intercultural theatre
Creators: name: Holman, Anna Caitlin
Publisher: name: University of British Columbia
Year: 2017

description: In the practice and production of intercultural theatre, language has held a variety of functions. However, the connection between language and culture in the theoretical models of intercultural theatre has been largely unexplored. The theories of linguistic anthropologists Dell Hymes, Richard Bauman, Joel Sherzer, and Charles Briggs postulate that language is a fundamental component of culture and that performative events present ideal sites for analysis. Mary Bucholtz, Kira Hall, and Norma Mendoza-Denton theorize that identity is a performative act of the self and other through language. Given these theories, this research asks: how does language function as a property of culture and identity in intercultural theatre? To answer this question, I have examined the role of language in two intercultural theatre productions which previewed in Vancouver, Canada in 2016. The analysis of these two works, Kayoi Komachi: A Noh Chamber Opera and Lady Sunrise, includes live and video-recorded performance analyses, script analysis, and interviews with the participating artists. This thesis demonstrates that language in intercultural theatre both informs cultural representation and influences the identities of the performers and their characters. With these findings, this research suggests that future models of intercultural theatre frame culture within a linguistic context.

description: We study the transmission of classical information in quantum channels. We present a decoding procedure that is very simple but still achieves the channel capacity. It is used to give an alternative straightforward proof that the classical capacity is given by the regularized Holevo bound. This procedure uses only projective measurements and is based on successive "yes"/"no" tests only.

description: $J/Ψ$-nuclear bound state energies are calculated for a range of nuclei by solving the Proca (Klein-Gordon) equation. Critical input for the calculations, namely the medium-modified $D$ and $D^*$ meson masses, as well as the nucleon density distributions in nuclei, are obtained from the quark-meson coupling model. The attractive potential originates from the $D$ and $D^*$ meson loops in the $J/Ψ$ self-energy in nuclear medium. It appears that $J/Ψ$-nuclear bound states should produce a clear experimental signature provided that the $J/Ψ$ meson is produced in recoilless kinematics.

description: We investigate the transmission and reflection survival probabilities for the chaotic stadium billiard with two holes placed asymmetrically. Classically, these distributions are shown to have algebraic or exponential decays depending on the choice of injecting hole and exact expressions are given for the first time and confirmed numerically. As there is no reported quantum theoretical or experimental analogue we propose a model for experimental observation of the asymmetric transport using semiconductor nano-structures and comment on the relevant quantum time-scales.

description: We measured high resolution Cu $L_3$ edge resonant inelastic x-ray scattering (RIXS) of the undoped cuprates La$_2$CuO$_4$, Sr$_2$CuO$_2$Cl$_2$, CaCuO$_2$ and NdBa$_2$Cu$_3$O$_6$. The dominant spectral features were assigned to $dd$ excitations and we extensively studied their polarization and scattering geometry dependence. In a pure ionic picture, we calculated the theoretical cross sections for those excitations and used them to fit the experimental data with excellent agreement. By doing so, we were able to determine the energy and symmetry of Cu-3$d$ states for the four systems with unprecedented accuracy and confidence. The values of the effective parameters could be obtained for the single ion crystal field model but not for a simple two-dimensional cluster model. The firm experimental assessment of $dd$ excitation energies carries important consequences for the physics of high $T_c$ superconductors. On one hand, having found that the minimum energy of orbital excitation is always $\geq 1.4$ eV, i.e., well above the mid-infrared spectral range, leaves to magnetic excitations (up to 300 meV) a major role in Cooper pairing in cuprates. On the other hand, it has become possible to study quantitatively the effective influence of $dd$ excitations on the superconducting gap in cuprates.

Stacked graphs and symmetric groups : modelling the conformation space of nucleic acids
Creators: name: Roosenmaallen, Morgan Antony
Publisher: name: University of British Columbia
Year: 2017

description: This work introduces a technique for approximating the conformation space of rigid and semi-rigid kinematic chains with finite inverse kinematic solutions using graph-like constructs called stacked graphs. The technique is developed in the context of nucleic acids, in particular ribonucleic acid (RNA), whose phosphate backbone can be modelled as a kinematic chain. Additionally, a process for identifying stable RNA conformations and likely conformational pathways is demonstrated. As a secondary result, a potentially novel relationship between stacked graphs and symmetric groups is uncovered and briefly investigated.

description: In the Higgs inflation scenario the Higgs field is strongly coupled to the Ricci scalar in order to drive primordial inflation. However, in its original form in pure metric formulation of gravity, the ultraviolet (UV) cutoff of the Higgs interactions and the Hubble rate are of the same magnitude, and this makes the whole inflationary evolution dependent of the unknown UV completion of the Higgs sector. This problem, the unitarity violation, plagues the Higgs inflation scenario. In this letter we show that, in the Palatini formulation of gravitation, Higgs inflation does not suffer from unitarity violation since the UV cutoff lies parametrically much higher than the Hubble rate so that unknown UV physics does not disrupt the inflationary dynamics. Higgs-Palatini inflation, as we call it, is, therefore, UV-safe, minimal and endowed with predictive power.

description: Graphical rule, describing that any single-mode homodyne detection turns a given continuous-variable (CV) graph state into a new one, is presented. Employing two simple graphical rules: local complement operation and vertex deletion (single quadrature-amplitude $\hat{x}$ measurement), the graphical rule for any single-mode quadrature component measurement can be obtained. The shape of CV weighted graph state may be designed and constructed easily from a given larger graph state by applying this graphical rule.

description: Approximately 1/4-1/2 of short duration Gamma-Ray Bursts are followed by variable X-ray emission lasting ~ 100 s with a fluence comparable or exceeding that of the initial burst itself. The long duration and significant energy of this `extended emission'(EE) poses a major challenge to the standard binary neutron star merger model. metzger08 recently proposed that the EE is powered by the spin-down of a strongly magnetized neutron star. However, the effects of surrounding material on the magnetar outflow have not yet been considered. Here we present time-dependent axisymmetric relativistic magnetohydrodynamic simulations of the interaction of the relativistic proto-magnetar wind with a surrounding 10^-1 10^-3 M_\odot envelope, which represents material ejected during the merger; the supernova following AIC; or via outflows from the accretion disk. The collision between the relativistic magnetar wind and the expanding ejecta produces a magnetized nebula inside the ejecta. A strong toroidal magnetic field builds up in the nebula, which drives a bipolar jet out through the ejecta, similar to the magnetar model developed in the case of long duration GRBs. We quantify the `break-out' time and opening angle of the jet theta_j as a function of the wind energy flux dot{E} and ejecta mass M_ej. We show that dot{E} and theta_j are inversely correlated, such that the beaming-corrected (isotropic) luminosity of the jet is primarily a function of M_ej. Both variability arguments, and the lower limit on the power of magnetar outflows capable of producing bright emission, suggest that the true opening angle of the magnetar jet must be relatively large. The model thus predicts a class of events for which the EE is observable with no associated short GRB. These may appear as long-duration GRBs or X-Ray Flashes, which may be detected by future all-sky X-ray survey missions.

description: Application of the standard canonical quantization rules of quantum field theory to macroscopic electromagnetism has encountered obstacles due to material dispersion and absorption. This has led to a phenomenological approach to macroscopic quantum electrodynamics where no canonical formulation is attempted. In this paper macroscopic electromagnetism is canonically quantized. The results apply to any linear, inhomogeneous, magnetodielectric medium with dielectric functions that obey the Kramers-Kronig relations. The prescriptions of the phenomenological approach are derived from the canonical theory.

description: Die Publikationslandschaft an PHs und FHs ist heterogen und unterscheidet sich von jener der Universitäten: Neben internationalen Journals spielen landessprachliche, anwendungsorientierte Fachzeitschriften eine wichtige Rolle. Eine Publikationsanalyse, die im Rahmen des Projektes OA-EASI (Open Access for Educational and Applied Sciences) durchgeführt wurde, hat gezeigt, dass unter den Journals, bei denen Autoren*innen aus FHs und PHs am häufigsten publizieren, praxisorientierte Publikationsorgane in den Landessprachen die grosse Mehrheit ausmachen. Diese Zeitschriften und Verlage stehen jedoch nicht im Fokus der nationalen und internationalen Bemühungen um Open Access. Es zeigt sich also, dass im Unterschied zu den Universitäten konsortiale Read & Publish-Agreements für die FHs und PHs einen vergleichsweise geringen Teil der Publikationslandschaft abdecken.
 Im Vortrag werden die Ergebnisse des im Sommer 2021 abgeschlossenen Projektes OA-EASI vorgestellt: Neben der breit angelegten Publikationsanalyse mit mehr als 17'000 Publikationen von FHs und PHs (2017-2019) und den Resultaten aus 10 Experteninterviews werden Erfahrungen diskutiert, die bei der Beratung zweier Zeitschriften aus dem genannten Bereich in Hinblick auf eine Transformation zu Open Access gemacht werden konnten.
 Zudem werden Überlegungen angestellt, wie Open Access im Kontext von FHs und PHs gezielter gefördert werden kann:
 Welche Open Access-Modelle eignen sich für diese tendenziell praxisorientierten Publikationen?
 Wie kann die Transformation von Zeitschriften hin zu Open Access finanziert werden?
 Welche Unterstützungsmassnamen braucht es bei einer solchen Umstellung?
 Für Finanzierungen von Flippings/Gold OA könnten ähnliche konsortiale Modelle in Frage kommen wie sie im Rahmen der Read&Publish-Agreements ausgearbeitet wurden. Bei Publikationen, die sich vornehmlich an eine nichtakademische Leserschaft wenden, könnte der Grüne Weg eine effiziente Alternative zur vollen Transformation sein. Ergänzend dazu verlangen Supportangebote für Verlage und Herausgeber*innen hinsichtlich Infrastruktur und rechtlicher Grundlagen besondere Aufmerksamkeit.

Termination of the system is achieved through pattern-based blocking. Previous approaches to related logics all rely on chain-based blocking. Besides being conceptually simple and suitable for efficient implementation, the pattern-based approach gives us a NExpTime complexity bound for the decision procedure.

description: The spiral magnetic structure and underlying spin lattice of BiMnFe2O6 are investigated by low-temperature neutron powder diffraction and density functional theory band structure calculations. In spite of the random distribution of the Mn3+ and Fe3+ cations, this compound undergoes a transition into an incommensurate antiferromagnetically ordered state below TN ~ 220 K. The magnetic structure is characterized by the propagation vector k=[0,beta,0] with beta ~ 0.14 and the P22_12_11'(0 β0)0s0s magnetic superspace symmetry. It comprises antiferromagnetic helixes propagating along the b-axis. The magnetic moments lie in the ac plane and rotate about pi*(1+beta) ~ 204.8 deg angle between the adjacent magnetic atoms along b. The spiral magnetic structure arises from the peculiar frustrated arrangement of exchange couplings in the ab plane. The antiferromagnetic coupling along the c-axis leads to the cancellation of electric polarization, and results in the lack of ferroelectricity in BiMnFe2O6.

description: Stimulated Brillouin interaction between sound and light, known to be the strongest optical nonlinearity common to all amorphous and crystalline dielectrics, has been widely studied in fibers and bulk materials but rarely in optical microresonators. The possibility of experimentally extending this principle to excite mechanical resonances in photonic microsystems, for sensing and frequency reference applications, has remained largely unexplored. The challenge lies in the fact that microresonators inherently have large free spectral range, while the phase matching considerations for the Brillouin process require optical modes of nearby frequencies but with different wavevectors. We rely on high-order transverse optical modes to relax this limitation. Here we report on the experimental excitation of mechanical resonances ranging from 49 to 1400 MHz by using forward Brillouin scattering. These natural mechanical resonances are excited in ~100 um silica microspheres, and are of a surface-acoustic whispering-gallery type.

description: The whole computer hardware industry embraced multicores. For these machines, the extreme optimisation of sequential algorithms is no longer sufficient to squeeze the real machine power, which can be only exploited via thread-level parallelism. Decision tree algorithms exhibit natural concurrency that makes them suitable to be parallelised. This paper presents an approach for easy-yet-efficient porting of an implementation of the C4.5 algorithm on multicores. The parallel porting requires minimal changes to the original sequential code, and it is able to exploit up to 7X speedup on an Intel dual-quad core machine.

description: We consider the 3-dimensional massive Gross-Neveu model at finite temperature as an effective theory for strong interactions. Using the Matsubara imaginary time formalism, we derive a closed form for the renormalized $T$-dependent four-point function. This gives a singularity, suggesting a phase transition. Considering the free energy we obtain the $T$-dependent mass, which goes to zero for some temperature. These results lead us to the conclusion that there is a second-order phase transition.

a novel missense mutation in IQSEC2 underlies Intellectual Disability in a Chinese Family

description: Intellectual disability (ID) is a very common heterogeneous disorder with a wide phenotypic spectrum. Over 1,700 OMIM genes have been associated with this condition, many of which reside on the X-chromosome. The IQSEC2 gene is located on chromosome X and encodes a guanine nucleotide exchange factor for the ADP ribosylation factor family of small GTPases. This gene is known to have a significant role in cytoskeletal organization, dendritic spine morphology and synaptic organization. Variants in IQSEC2 cause moderate to severe intellectual disability in males and a variable phenotype in females because this gene escapes from X-chromosome inactivation. In this study, we investigated a 11-years old Chinese boy with developmental delay and mental retardation. Both the younger brother and sister of the proband was also presented with developmental delay and mental retardation. Targeted next generation sequencing identified a novel missense (c.2422G>C) mutation in exon 6 of IQSEC2 gene that causes replacement of evolutionarily extremely conserved glycine by arginine (p.Gly808Arg). Sanger sequencing confirmed that this mutation is co-segregates with disease phenotype in this family diagnosed with an X-linked form of ID. Functional assays revealed that recombinant IQSEC2 G808R was not able to catalyze GDP-GTP exchange on Arf6 as efficiently as wild-type IQSEC2. In silico protein structure analysis showed that this mutation is destabilizing. The G808R mutation is located outside of the IQSEC2 protein, so it did not cause any steric clash. In conclusion, our results strongly suggest that the novel mutation in IQSEC2 is the underlying cause of XLID in the MRX78 family.

description: Quantum fields in compact stars can be amplified due to a semiclassical instability. This generic feature of scalar fields coupled to curvature may affect the birth and the equilibrium structure of relativistic stars. We point out that the semiclassical instability has a classical counterpart, which occurs exactly in the same region of the parameter space. For negative values of the coupling parameter the instability is equivalent to the well-known "spontaneous scalarization" effect: the plausible end-state of the instability is a static, asymptotically flat equilibrium configuration with nonzero expectation value for the quantum fields, which is compatible with experiments in the weak-field regime and energetically favored over stellar solutions in general relativity. For positive values of the coupling parameter the new configurations are energetically disfavored, and the end-point of the instability remains an open and interesting issue. The vacuum instability may provide a natural mechanism to produce spontaneous scalarization, leading to new experimental opportunities to probe the nature of vacuum energy via astrophysical observations of compact stars.

description: We explore the phenomenology of Grand Unified Models based on the E_6 group, focusing on the Z' with suppressed couplings to leptons that can appear in such models. We find that this Z' can accommodate the W+dijets anomaly reported by the CDF collaboration. Furthermore, a viable dark matter candidate in the form of a right-handed sneutrino is also present within the fundamental 27-dimensional representation of E_6. Through its sizable couplings to the Z', the dark matter is predicted to possess an elastic scattering cross section with neutrons which can generate the signals reported by the CoGeNT and DAMA/LIBRA collaborations. To avoid being overproduced in the early universe, the dark matter must annihilate to leptons through the exchange of charged or neutral fermions which appear in the 27 of E_6, providing an excellent fit to the gamma ray spectrum observed from the Galactic Center by the Fermi Gamma Ray Space Telescope.

description: Topological quantum computation provides an elegant way around decoherence, as one encodes quantum information in a non-local fashion that the environment finds difficult to corrupt. Here we establish that one of the key operations---braiding of non-Abelian anyons---can be implemented in one-dimensional semiconductor wire networks. Previous work [Lutchyn et al., arXiv:1002.4033 and Oreg et al., arXiv:1003.1145] provided a recipe for driving semiconducting wires into a topological phase supporting long-sought particles known as Majorana fermions that can store topologically protected quantum information. Majorana fermions in this setting can be transported, created, and fused by applying locally tunable gates to the wire. More importantly, we show that networks of such wires allow braiding of Majorana fermions and that they exhibit non-Abelian statistics like vortices in a p+ip superconductor. We propose experimental setups that enable the Majorana fusion rules to be probed, along with networks that allow for efficient exchange of arbitrary numbers of Majorana fermions. This work paves a new path forward in topological quantum computation that benefits from physical transparency and experimental realism.

description: The Exceptional Supersymmetric (SUSY) Standard Model predicts three families of Higgs doublets plus three Higgs singlets, where one family develops vacuum expectation values (VEVs), while the remaining two which do not are called Inert. The model can account for the dark matter relic abundance if the two lightest Inert neutralinos, identified as the (next-to) lightest SUSY particles ((N)LSPs), have masses close to half the Z mass. In this case we find that the usual SM-like Higgs boson decays more than 95% of the time into either LSPs or NLSPs. The latter case produces a final state containing two leptons l^{+}l^{-} with an invariant mass less than or about 10 GeV. We illustrate this scenario with a set of benchmark points satisfying phenomenological constraints and the WMAP dark matter relic abundance. This scenario also predicts other light Inert chargino and neutralino states below 200 GeV, and large LSP direct detection cross-sections close to current limits and observable soon at XENON100.

description: The decays $χ_{cJ}\toγV$ ($V=ϕ, ρ^0, ω$) are studied with a sample of radiative $\psip\toγχ_{cJ}$ events in a sample of $(1.06\pm0.04)\times 10^{8} \psip$ events collected with the BESIII detector. The branching fractions are determined to be: ${\cal B}(χ_{c1}\to γϕ)=(25.8\pm 5.2\pm 2.3)\times 10^{-6}$, ${\cal B}(χ_{c1}\to γρ^0)=(228\pm 13\pm 22)\times 10^{-6}$, and ${\cal B}(χ_{c1}\to γω)=(69.7\pm 7.2\pm 6.6)\times 10^{-6}$. The decay $χ_{c1}\to γϕ$ is observed for the first time. Upper limits at the 90% confidence level on the branching fractions for $χ_{c0}$ and $\chict$ decays into these final states are determined. In addition, the fractions of the transverse polarization component of the vector meson in $χ_{c1}\to γV$ decays are measured to be $0.29_{-0.12-0.09}^{+0.13+0.10}$ for $χ_{c1}\to γϕ$, $0.158\pm 0.034^{+0.015}_{-0.014}$ for $χ_{c1}\to γρ^0$, and $0.247_{-0.087-0.026}^{+0.090+0.044}$ for $χ_{c1}\to γω$, respectively. The first errors are statistical and the second ones are systematic.

description: Ward-Takahashi identities of the colored Boulatov model are derived using a generic unitary field transformation. In a specific instance, this generic transformation turns out to be a symmetry of the interaction so that particular classes of reduced Ward-Takahashi identities for that symmetry are consequently identified and interpreted.

description: In this paper, forward-backward asymmetry and differential cross section of top quark in flavor violating $Z'$ model up to $\mathscr{O}(α_s^2 α_X)$ at Tevatron are calculated. In order to account for the top observed large forward-backward asymmetry, the new coupling $g_X$ among $Z'$ and quarks will be not much less than strong coupling constant $g_s$. After including the new higher order correction, the differential cross section can fit the data better than those only including the leading contributions from $Z'$, while the forward-backward asymmetry is still in agreement with the measurement.

Small volume cell culture technology for the analysis of clonal heterogeneity in mammalian cell populations

description: The ability to culture individual cells provides a unique method to assess the heterogeneity of mammalian cell populations. However, there are many challenges when scaling down culture systems due to the complexity of re-creating a stimulating environment at the clonal level. Small volume culture systems such as integrated microfluidic platforms offer the potential to radically alter the throughput of clonal screening through the use of time-lapse imaging, dynamic stimulus control and economy of scale. In particular, the use of automated fluidic control allows for the characterization of single cells in a dynamic microenvironment similar to large-scale culture. This thesis describes how small volume cell culture practices such as the use of conditioned medium and microfluidic technology can be implemented to isolate large numbers of cells in small volumes and evaluate clonal populations under precise medium conditions. For a Chinese Hamster Ovary (CHO) cell system normal growth kinetics and specific productivity were sustained in small volumes. When exposed to conditioned medium from a parental CHO line, clones cultured at sub-mL scales matched the performance of large-scale cultures. A microfluidic bead assay was developed to detect Immunoglobulin G titers secreted from clones in nL volumes. The combination of microfluidic conditioned medium perfusion with the magnetic bead assay allowed for clonal productivity to be evaluated under simulated fed-batch conditions. Lastly, microfluidic cell culture was demonstrated on a human embryonic stem cell (hESC) system through the robust generation of colonies derived from single cells. hESCs propagated in the microfluidic system were observed to match the growth kinetics, marker expression and colony morphologies of larger cultures, while resolving response heterogeneity during differentiation induction. This thesis demonstrates how high-throughput, small volume culture systems can be used to screen clonal populations for therapeutic applications under complex culture conditions.

description: Ein Problem zahlreicher APC-freier Open-Access-Zeitschriften aus dem akademischen Umfeld ist, dass verlegerische Standards nicht oder nicht vollständig beachtet werden. Besonders für wissenschaftsnahe Open-Access-Zeitschriften ist es aber wichtig, sich mit diesen Standards zu befassen, um mit Zeitschriften bei kommerziellen Anbietern mithalten zu können. Verschiedene Organisationen aus dem Open-Access-Umfeld haben Kriterien entwickelt, die eine hohe formale Qualität von Open-Access-Zeitschriften garantieren. Zu nennen sind hier v.a. die technical implementation guidelines von Plan S, die Kriterien zur Erreichung des DOAJ Seal sowie die Mitgliedschaftskriterien der Open Access Scholarly Publishing Association (OASPA). Einige der von diesen Organisationen und Initiativen angewendeten Kriterien überschneiden sich, andere sind komplementär. Die Kriterien können verschiedenen Bereichen zugeordnet werden, wie z. B. Open-Access-Standards, Identifier, Metadaten und Richtlinien bzw. Webseiteninhalte. Für TIB Open Publishing, die neue Open-Access-Publikationsplattform der Technischen Informationsbibliothek (TIB), haben diese formalen Qualitätskriterien hohe Relevanz, da Zeitschriften und Konferenzpublikationen, die mit TIB Open Publishing veröffentlichen, von vorne herein konform mit aktuellen Förderrichtlinien (z.B. Plan S) und Datenbanken (z.B. DOAJ) sein sollen, um ein möglichst große Reichweite und Sichtbarkeit zu erreichen. Im Rahmen des Aufbaus von TIB Open Publishing sind diese Kriterien daher zusammengetragen worden und sollen im Vortrag anhand einiger Beispiele veranschaulicht werden. Dabei wird auch die Übertragbarkeit auf andere Plattformen und Zeitschriften analysiert und aufbereitet.

description: In this paper, we compute holographically the two-point and three-point functions of giant gravitons with open strings. We consider the maximal giant graviton in $S^5$ and the string configurations corresponding to the ground states of Z=0 and Y=0 open spin chain, and the spinning string in AdS$_5$ corresponding to the derivative type impurities in Y=0 or Z=0 open spin chain as well. We treat the D-brane and open string contribution separately and find the corresponding D3-brane and string configurations in bulk which connect the composite operators at the AdS$_5$ boundary. We apply a new prescription to treat the string state contribution and find agreements for the two-point functions. For the three-point functions of two giant gravitons with open strings and one certain half-BPS chiral primary operator, we find that the D-brane contributions to structure constant are always vanishing and the open string contribution for the Y=0 ground state is in perfect match with the prediction in the free field limit.

description: Basic proof-search tactics in logic and type theory can be seen as the root-first applications of rules in an appropriate sequent calculus, preferably without the redundancies generated by permutation of rules. This paper addresses the issues of defining such sequent calculi for Pure Type Systems (PTS, which were originally presented in natural deduction style) and then organizing their rules for effective proof-search. We introduce the idea of Pure Type Sequent Calculus with meta-variables (PTSCalpha), by enriching the syntax of a permutation-free sequent calculus for propositional logic due to Herbelin, which is strongly related to natural deduction and already well adapted to proof-search. The operational semantics is adapted from Herbelin's and is defined by a system of local rewrite rules as in cut-elimination, using explicit substitutions. We prove confluence for this system. Restricting our attention to PTSC, a type system for the ground terms of this system, we obtain the Subject Reduction property and show that each PTSC is logically equivalent to its corresponding PTS, and the former is strongly normalising iff the latter is. We show how to make the logical rules of PTSC into a syntax-directed system PS for proof-search, by incorporating the conversion rules as in syntax-directed presentations of the PTS rules for type-checking. Finally, we consider how to use the explicitly scoped meta-variables of PTSCalpha to represent partial proof-terms, and use them to analyse interactive proof construction. This sets up a framework PE in which we are able to study proof-search strategies, type inhabitant enumeration and (higher-order) unification.

description: We present Herschel SPIRE-FTS observations of Arp~220, a nearby ULIRG. The FTS continuously covers 190 -- 670 microns, providing a good measurement of the continuum and detection of several molecular and atomic species. We detect luminous CO (J = 4-3 to 13-12) and water ladders with comparable total luminosity; very high-J HCN absorption; OH+, H2O+, and HF in absorption; and CI and NII. Modeling of the continuum yields warm dust, with T = 66 K, and an unusually large optical depth of ~5 at 100 microns. Non-LTE modeling of the CO shows two temperature components: cold molecular gas at T ~ 50 K and warm molecular gas at T ~1350 K. The mass of the warm gas is 10% of the cold gas, but dominates the luminosity of the CO ladder. The temperature of the warm gas is in excellent agreement with H2 rotational lines. At 1350 K, H2 dominates the cooling (~20 L_sun/M_sun) in the ISM compared to CO (~0.4 L_sun/M_sun). We found that only a non-ionizing source such as the mechanical energy from supernovae and stellar winds can excite the warm gas and satisfy the energy budget of ~20 L_sun/M_sun. We detect a massive molecular outflow in Arp 220 from the analysis of strong P-Cygni line profiles observed in OH+, H2O+, and H2O. The outflow has a mass > 10^{7} M_sun and is bound to the nuclei with velocity < 250 km/s. The large column densities observed for these molecular ions strongly favor the existence of an X-ray luminous AGN (10^{44} ergs/s) in Arp 220.

description: We consider Zeeman field effects on a Spin Bose-Metal (SBM) phase on a two-leg triangular ladder. This phase was found in a spin-1/2 model with ring exchanges [D. N. Sheng et. al., Phys. Rev. B {\bf 79}, 205112 (2009)], and was also proposed to appear in an interacting electronic model with longer-ranged repulsion [Lai et. al., Phys. Rev. B {\bf 81}, 045105 (2010)]. Using bosonization of a spinon-gauge theory, we study the stability of the SBM phase and its properties under the field. We also explore phases arising from potential instabilities of the SBM; in all cases, we find a gap to spin-1 excitations while spin-nematic correlations are power law. We discuss two-dimensional analogues of these phases where spinons can pair with their own species.
