description: We demonstrate that the interfacial dipole associated with bonding across the SrTiO3/Si heterojunction can be tuned through space charge, thereby enabling the band alignment to be altered via doping. Oxygen impurities in Si act as donors that create space charge by transferring electrons across the interface into SrTiO3. The space charge induces an electric field that modifies the interfacial dipole, thereby tuning the band alignment from type-II to type-III. The transferred charge, resulting in built-in electric fields, and change in band alignment are manifested in electrical transport and hard x-ray photoelectron spectroscopy measurements. Ab initio models reveal the interplay between polarization and band offsets. We find that band offsets can be tuned by modulating the density of space charge across the interface. Functionalizing the interface dipole to enable electrostatic altering of band alignment opens new pathways to realize novel behavior in semiconducting heterojunctions.

description: We consider Higgs boson production by gluon fusion in hadron collisions. We study the doubly-differential transverse-momentum (q_T) and rapidity (y) distribution of the Higgs boson in perturbative QCD. In the region of small q_T (q_T << M_H, M_H being the mass of the Higgs boson), we include the effect of logarithmically-enhanced contributions due to multiparton radiation to all perturbative orders. We use the impact parameter and double Mellin moments to implement and factorize the multiparton kinematics constraint of transverse- and longitudinal-momentum conservation. The logarithmic terms are then systematically resummed in exponential form. At small q_T, we perform the all-order resummation of large logarithms up to next-to-next-to-leading logarithmic accuracy, while at large q_T (q_T ~ M_H), we apply a matching procedure that recovers the fixed-order perturbation theory up to next-to-leading order. We present quantitative results for the differential cross section in q_T and y at the LHC, and we comment on the comparison with the q_T cross section integrated over y.

A behavioural study of human responses to the arctic and antarctic environments
Creators: name: Mocellin, Jane Schneider Pereyron
Publisher: name: University of British Columbia

description: This is a study of human response to the Arctic and Antarctic environments. It is based on two sources of data: the content analysis of original diaries of polar explorers, and the behavioural evaluation of contemporary crews in polar locations. In the latter, four polar stations were chosen, two in each polar region with a total of fifty-five experimental subjects. Twenty-seven other subjects acted as controls for both polar regions: a northern control group located at a semi-isolated site in Canada, and the southern group located in an Argentinian city. Methods applied in this research included the design and coding of categories which were content analyzed from the original diaries of explorers, and on-site procedures. On-site procedures included psychometric material, participant-observation reports and unstructured interviews. Fifteen behavioural measures within the domain of personality, perception of the environment, affection, social stress and community behaviour were administered. It was hypothesized that the human response would be similar in both polar regions because of environmental and sociological similarities, and that the polar setting would affect men and women in a negative way. Results showed that: (i) the polar environment is not perceived as stressful by the crews - a low anxiety state across both polar regions was found, (ii) traumatic experiences of the explorers had led to the perception of the environment in a negative perspective - yet the winter seemed to be a relaxing phase for the crews rather than stressful, (iii) personnel stationed at polar sites may possess special characteristics which distinguish them from the majority of the population, (iv) although cross-cultural differences exist, they are not as strong as might be anticipated - the environment exerts a unifying influence, (v) differences in gender-response are difficult to assess due to the small number of women subjects, but some differences with controls were noted.

description: This thesis focuses on Muslim literature, a diverse literature that
      includes literary works produced in English by Muslim authors of different
      ethnicities and cultural heritages. Uniquely, it approaches this
      literature from a religious perspective and concentrates on the religious
      domain, which has been usually avoided by postcolonial studies examining
      Muslim literature. Muslim literature is usually analysed from a secular
      perspective that focuses on highlighting cultural diversity among Muslim
      authors but sheds limited light on their religious diversity. This secular
      approach dominates partly because of the limitation of postcolonial theory
      in relation to Islam, and partly because of the conflict created between
      Islam and literature by Muslim critics, both secular and religious.

      In focusing on the religious rather than the cultural domain, I limit the
      scope of my examination to include only contemporary Muslim writers who
      have the same ethnicity and similar cultural backgrounds. To be precisely,
      I concentrate on contemporary British Arab Muslim writers, specifically,
      Fadia Faqir (1956–, of Jordanian origin) and Leila Aboulela (1964–, of
      Sudanese and Egyptian origin). I also select Islamic feminism itself as a
      site of religious diversity. My main objective is to compare and contrast
      Islamic feminist consciousness as revealed by Aboulela and Faqir, whether
      explicitly or implicitly, in their fiction that they produced from the
      1990s to the 2010s. My aim in comparing and contrasting the Islamic
      feminism of Aboulela and Faqir is to illustrate my argument that their
      Islamic feminism varies enormously from a religious perspective. Faqir
      focuses on giving her female Muslim protagonists a voice and power in
      order to withstand patriarchal Arab cultural and social traditions and an
      inherited legal system and doctrinal rules that subvert Muslim women,
      whereas Aboulela makes the Islamic faith a source of spiritual
      emancipation that strengthens her female Muslim protagonists internally.

      This thesis is important because it contributes to expanding existing
      literary criticism in relation to Muslim literature, which is achieved by
      exploring the feminist consciousness of Aboulela and Faqir, two
      contemporary British Arab Muslim authors who emphasise the centrality of
      Islam in their postcolonial feminist fiction. It is also achieved by using
      Islamic feminism as a key methodology that provides a better understanding
      of how Aboulela and Faqir use Islam as a framework for their feminism,
      what challenges they face in doing so and how they manage to overcome
      these challenges.

description: We explore Lie superalgebra deformations of the Killing superalgebras of some ten-dimensional supergravity backgrounds. We prove the rigidity of the Poincare superalgebras in types I, IIA and IIB, as well as of the Killing superalgebra of the Freund-Rubin vacuum of type IIB supergravity. We also prove rigidity of the Killing superalgebras of the NS5, D0, D3, D4 and D5 branes, whereas we exhibit the possible deformations of the D1, D2, D6 and D7 brane Killing superalgebras, as well as of that of the type II fundamental string solutions. We relate the superalgebra deformations of the D2 and D6 branes to those of the (delocalised) M2 brane and the Kaluza-Klein monopole, respectively. The good behaviour under Kaluza-Klein reduction suggests that the deformed superalgebras ought to have a geometric interpretation.

description: This paper presents a summary of the first 10 years of operating the Hobby-Eberly Telescope (HET) in queue mode. The scheduling can be quite complex but has worked effectively for obtaining the most science possible with this uniquely designed telescope. The queue must handle dozens of separate scientific programs, the involvement of a number of institutions with individual Telescope Allocation Committees as well as engineering and instrument commissioning. We have continuously revised our queue operations as we have learned from experience. The flexibility of the queue and the simultaneous availability of three instruments, along with a staff trained for all aspects of telescope and instrumentation operation, have allowed optimum use to be made of variable weather conditions and have proven to be especially effective at accommodating targets of opportunity and engineering tasks. In this paper we review the methodology of the HET queue along with its strengths and weaknesses.

Development of a design procedure for greenhouse solar heating systems
Creators: name: Lau, Anthony Ka-Pong
Publisher: name: University of British Columbia
Year: 2010

description: The techniques of computer modeling and simulations are used to develop a design procedure for greenhouse solar heating systems. In this study a flexible computer program was written based on mathematical models that describe the various subsystems of the solar heating system that uses the greenhouse as the solar collector. Extensive simulation runs were carried out for predicting system thermal performance, and subsequently correlations were established between dimensionless variables and long term system performance. The combined greenhouse thermal environment - thermal storage model along with the empirical relationships and the values of constants approximated in the simulation yielded reasonably accurate computed results compared to observed data. The computer model was then applied to predict the system behaviour using long-term average climatological data as forcing functions. A parametric study was made to investigate the effects of various factors pertinent to greenhouse construction and thermal energy storage characteristics on system performance. The key performance indices were defined in terms of the 'total solar contribution' and the 'solar heating fraction'. Correlations were developed between monthly solar load ratio and total solar contribution, and between total solar contribution and solar heating fraction. The result is a simplified design method that covers a number of alternative design options. It requires users to obtain monthly average climatological data and determine the solar heating fraction in a sequence of computational steps. A crop photosynthesis model was used to compute the net photosynthetic rate of a greenhouse tomato canopy; the result may be used to compare crop performance under different aerial environments in greenhouses equipped with a solar heating system. This research program had attempted to generate technical information for a number of design alternatives, and as design optimization of greenhouse solar heating is subject to three major criteria of evaluation: thermal performance, crop yield and cost, recommendations were put forward for future work on economic analysis as the final step required for selecting the most cost effective solution for a given design problem.

description: We prove that the classical set of moves for standard spines of 3-manifolds (i.e. the MP-move and the V-move) does not suffice to relate to each other any two standard skeleta of a 3-manifold with marked boundary. We also describe a condition on the 3-manifold with marked boundary that tells whether the generalised set of moves, made up of the MP-move and the L-move, suffices to relate to each other any two standard skeleta of the 3-manifold with marked boundary. For the 3-manifolds with marked boundary that do not fulfil this condition, we give three other moves: the CR-move, the T1-move and the T2-move. The first one is local and, with the MP-move and the L-move, suffices to relate to each other any two standard skeleta of a 3-manifold with marked boundary fulfilling another condition. For the universal case, we prove that the non-local T1-move and T2-move, with the MP-move and the L-move, suffice to relate to each other any two standard skeleta of a generic 3-manifold with marked boundary. As a corollary, we get that disc-replacements suffice to relate to each other any two standard skeleta of a 3-manifold with marked boundary.

description: Using a Ginzburg-Landau model, we study the phase transition behavior of compressible Ising systems at constant volume by varying the temperature $T$ and the applied magnetic field $h$. We show that two phases can coexist macroscopically in equilibrium within a closed region in the $T$-$h$ plane. It occurence is favored near tricriticality. We find a field-induced critical point, where the correlation length diverges, the difference of the coexisting two phases and the surface tension vanish, but the isothermal magnetic susceptibility does not diverge in the mean field theory. We also investigate phase ordering numerically.

Grazing, non-transiting disintegrating exoplanets observed with the planned Ariel space observatory -- A case study using Kepler-1520b

Subjects: subject: Earth and Planetary Astrophysics (astro-ph.EP)
subject: FOS: Physical sciences

description: Disintegrating/evaporating rocky exoplanets can be observed not only as transiting planets, but also in a grazing, non-transiting regime, where the solid body of the planet does not transit, but part of the comet-like tail can transit. In this case the forward scattering on the escaping particles is the dominant process, which amplifies the photometric signal of the parent star detected by the observer. The change in the flux is small, about 10^-3 (1000 ppm) at the best properties of the planetary system, but if the observation is enough precise, the detection is possible. The planned Ariel space observatory is designed to achieve a stability of < 100 ppm (the goal is 10 ppm) over the temporal bandwidth of the transit, typically less than 10 hours. In this case study we took the disintegrating exoplanet Kepler-1520b and changed the orbital properties of the system to get a grazing, non-transiting orbit scenario, and investigated, how different particle sizes, species, Ariel observational channels, and other factors affect the amplitude of the forward-scattering peak, and the detectability of the scattering event. Our most important result is that the forward-scattering amplitude is not sensitive to the dust composition, but is very sensitive to the particle size, observational channel, and other factors. These factors can reduce mainly the detectability of 1-micron grains. 0.1-micron grains will be detectable at short wavelengths. 0.01-micron grains generate long and very small forward scattering amplitude, which is below the detection limit. Based on our results we can conclude that using Ariel will be possible to detect and investigate not only transiting, but also grazing, non-transiting disintegrating exoplanets based on the forward scattering. From the viewpoint of such objects the big advantage of Ariel will be the possibility of multiwavelength observations.

description: Comparative spectroscopic investigation of Biphenyl-4-carboxylic acid (BCA), 4-Acetylbiphenyl (ACB) and 2,4-difluorobiphenyl (DFB) are obtained by using Density Functional Theory (DFT) with B3LYP functional at 6-311++G(d, p) basis set. The vibrational assignments have been proposed with aid of the results of Normal Coordinate Analysis (NCA). The effects of carboxyl, acetyl and fluoro substituents on the vibrational frequencies of biphenyl have been investigated and compared. The molecular stability and bond strength was investigated by applying the Natural Bond Orbital (NBO) analysis. The other molecular properties like Mulliken charge analysis, HOMO-LUMO analysis and Molecular Electrostatic Potential (MESP) of the title compounds have been reported. In vitro analysis have been performed with two fungal pathogens Aspergillus niger and Candida albicans using well diffusion method. BCA compound exhibited excellent activity against the Aspergillus niger with zone of inhibition values in the range of 22 and 25 mm in 40 and 80 µl with 10 mg/ml. Molecular docking studies of the most active compound are carried out, and results showed reasonable binding modes in the fungicide active site of phytase protein Fophys and Succinate dehydrogenase (SDH) proteins. A preliminary Structure-Activity Relationship study of the biphenyl derivatives has led to the recognition of some important structural requirements for antifungal activity. Furthermore the fungicide-likeness analysis of BCA, DFB and ACB compounds have been developed to predict its fungicide activity by using fungiPAD webtool.
Cartel Stability, Mark-Up Cyclicality and Government Spending Multipliers

description: Mark-up cyclical behaviour is relevant in determining the size of government spending multiplier on output. While theoretical literature priviliged the counteryclical hypothesis, empirical evidence is far from being conclusive. Based on seminal Rotemberg and Saloner (1986) contribution, we build a theoretical framework based on Bertrand duopoly, stochastic demand and product differentiation, where the analysis of cartel stability under partial collusion points towards procyclical pricing. According to the intensity of marginal cost cyclicality, this can produce a procyclical mark up or - at least- render it less countercyclical than expected, with relevant effects on the transmission mechanism of government spending stimuli.
Emotional engagement and brain potentials: repetition in affective picture processing

Subjects: M-PSI/01 Psicologia generale

description: The present thesis addresses several experimental questions regarding the nature of the processes underlying the larger centro-parietal Late Positive Potential (LPP) measured during the viewing of emotional(both pleasant and unpleasant) compared to neutral pictures. During a passive viewing condition, this modulatory difference is significantly reduced with picture repetition, but it does not completely habituate even after a massive repetition of the same picture exemplar. In order to investigate the obligatory nature of the affective modulation of the LPP, in Study 1 we introduced a competing task during repetitive exposure of affective pictures. Picture repetition occurred in a passive viewing context or during a categorization task, in which pictures depicting any mean of transportation were presented as targets, and repeated pictures (affectively engaging images) served as distractor stimuli. Results indicated that the impact of repetition on the LPP affective modulation was very similar between the passive and the task contexts, indicating that the affective processing of visual stimuli reflects an obligatory process that occurs despite participants were engaged in a categorization task.
In study 2 we assessed whether the decrease of the LPP affective modulation persists over time, by presenting in day 2 the same set of pictures that were massively repeated in day 1. Results indicated that the reduction of the emotional modulation of the LPP to repeated pictures persisted even after 1-day interval, suggesting a contribution of long-term memory processes on the affective habituation of the LPP. Taken together, the data provide new information regarding the processes underlying the affective modulation of the late positive potential.

description: Three dinuclear complexes of composition [NiII2(L)2][ClO4]2 and [CuII2(L)2(OClO3)2].3H2O have been synthesized using a new tripodal ligand [(2-pyridyl)methyl](2-benzyl)-aminomethyl}-phenol (HL)], in its deprotonated form, providing a N2O donor set. Crystallographic analyses reveal that [CuII2(L)2(OClO3)2].3H2O has a diphenoxo-bridged structure. In [CuII2(L)2(OClO3)2].3H2O, each metal center is MIIN2O3-coordinated with a square-pyramidal environment for each copper(II) center. In this work, the molecular structure, harmonic vibrational frequencies and UV-Vis of [NiII2(L)2]2+ and [CuII2(L)2]2+ has been explored. With the help of density functional theory (DFT)/B3LYP techniques and LANL2DZ as a basis set, the ground-state molecule shape and vibrational frequencies were computed. The basic vibrations were allocated using the VEDA program to compute the potential energy distribution (PED) of the vibrational modes. The band gap energies of the title complexes ([NiII2(L)2]2+ and [CuII2(L)2]2+) are 3.21 eV and 1.59 eV, respectively, according to HOMO-LUMO energies. The maximal absorption wavelength and band gap energy of the title complexes were calculated theoretically using the UV absorption spectra. MEP analysis identifies electrophilic and nucleophilic sites. Hirshfeld surface analysis was used to characterize the 3D intermolecular interactions in ([NiII2(L)2]2+ and [CuII2(L)2]2+) of the crystal surface, whereas fingerprint plots were used to explain the 2D interactions. The biological activity of the complexes was investigated using molecular docking.

description: We compute in small temperature expansion the two-loop renormalization constants and the three-loop coefficient of the beta-function, that is the first non-universal term, for the sigma-model with O(N) invariance on the triangular lattice at N=-1. The partition function of the corresponding Grassmann theory is, for negative temperature, the generating function of unrooted forests on such a lattice, where the temperature acts as a chemical potential for the number of trees in the forest. To evaluate Feynman diagrams we extend the coordinate space method to the triangular lattice.

Creators: name: Johnson, Robert Bennett
Publisher: name: University of British Columbia
Year: 2010

description: The inter and intra-observer reliabilities of data collected by observers trained in the use of the Coach Analysis Instrument (CAI) are reported. The CAI is part of the Computerized Coaching Analysis System (CCAS). The CAI collects data related to the learning environment created by the coach in a team-sport practice situation. Both inter and intra-observer reliabilities are reported for each of the instrument's seven dimensions as well as for the overall instrument. The reliability measures reported are Total Percent Agreement (T) and Cohen's kappa (K). Recommendations pertaining to the development of systematic observation instruments, training program considerations, and reliability measures are presented and discussed.

description: Important biological compounds, namely, methyl 3-amino-4-(4-bromophenyl)thiophene-2-carboxylate (BPTC) and methyl 3-amino-4-(4-chlorophenyl)thiophene-2-carboxylate (CPTC), were characterized using complementary techniques of Fourier transform infrared (FT-IR), Raman spectroscopy. Nuclear magnetic resonance spectroscopy (NMR) confirmed the structural features, while Ultra Violet–Visible Spectroscopy was used to investigate the electronic properties of both compounds. The quantum chemical calculations for both compounds were performed using the DFT/B3LYP functional with the 6-311++G(d,p) basis set. This study computes electrostatic potential observation, electron localization function (ELF) assessment, and atoms-in-molecules (AIM) analysis. In the present investigation, the global hardness, chemical softness, electrophilicity, nucleophilicity indices, and dipole moment of both compounds were calculated. In addition, a molecular docking analysis was conducted to determine the binding potential of target molecules with protein tyrosine phosphatase. A 200-ns molecular dynamics (MDs) simulation had been performed to assess the compound’s binding stability.
Spin foam model from canonical quantization

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

description: We suggest a modification of the Barrett-Crane spin foam model of 4-dimensional Lorentzian general relativity motivated by the canonical quantization. The starting point is Lorentz covariant loop quantum gravity. Its kinematical Hilbert space is found as a space of the so-called projected spin networks. These spin networks are identified with the boundary states of a spin foam model and provide a generalization of the unique Barrette-Crane intertwiner. We propose a way to modify the Barrett-Crane quantization procedure to arrive at this generalization: the B field (bi-vectors) should be promoted not to generators of the gauge algebra, but to their certain projection. The modification is also justified by the canonical analysis of Plebanski formulation. Finally, we compare our construction with other proposals to modify the Barret-Crane model.

description: Break junctions in noble‐metal films can exhibit electroluminescence (EL) through inelastic electron tunneling. The EL spectrum can be tuned by depositing a single‐layer crystal of a transition‐metal dichalcogenide (TMDC) on top. Whereas the emission from the gaps between silver or gold nanoparticles formed in the break junction is spectrally broad, the hybrid metal/TMDC structure shows distinct luminescence from the TMDC material. The EL from individual hotspots is found to be linearly polarized, with a polarization axis apparently oriented randomly. Surprisingly, the degree of polarization is retained in the EL from the TMDC monolayer at room temperature. In analogy to polarized photoluminescence experiments, such polarized EL can be interpreted as a signature of valley‐selective transitions, suggesting that spin‐flip transitions and dephasing for excitons in the K valleys are of limited importance. However, polarized EL may also originate from the metal nanoparticles formed under electromigration which constitute optical antenna structures. Such antennae can apparently change over time since jumps in the polarization are observed in bare silver‐nanoparticle films. Remarkably, photon‐correlation spectroscopy reveals that gold‐nanoparticle films exhibit signatures of deterministic single‐photon emission in the EL, suggesting a route to designing room‐temperature polarized single‐photon sources with tunable photon energy through the choice of TMDC overlayer.

description: Reinforcement Learning (RL) presents a new approach for controlling Adaptive Optics (AO) systems for Astronomy. It promises to effectively cope with some aspects often hampering AO performance such as temporal delay or calibration errors. We formulate the AO control loop as a model-based RL problem (MBRL) and apply it in numerical simulations to a simple Shack-Hartmann Sensor (SHS) based AO system with 24 resolution elements across the aperture. The simulations show that MBRL controlled AO predicts the temporal evolution of turbulence and adjusts to mis-registration between deformable mirror and SHS which is a typical calibration issue in AO. The method learns continuously on timescales of some seconds and is therefore capable of automatically adjusting to changing conditions.

description: In this research work, the high-yielding and simple synthesis of 5-substituted 1H-tetrazoles derivatives through the one-pot three-component reaction of aldehydes, hydroxylamine hydrochloride and sodium azide catalyzed by MNPs-Picolylamine-Cu(OAc)2 nanocomposite in water under microwave irradiation has been reported. The MNPs-Picolylamine-Cu(OAc)2 nanocomposite is successfully fabricated through the immobilization of copper (II) acetate stabilized on magnetic Fe3O4 nanoparticles modified with Picolylamine [MNPs-Picolylamine-Cu(OAc)2] and then is well analyzed by various techniques such as FT-IR, XRD, TGA, SEM, TEM, EDS, VSM and ICP-OES. At the end of the reaction, the MNPs-Picolylamine-Cu(OAc)2 catalyst can be easily recycled and reused and the products obtained had high efficiency and purity.

description: We consider ferromagnetic Ising models on graphs that converge locally to trees. Examples include random regular graphs with bounded degree and uniformly random graphs with bounded average degree. We prove that the "cavity" prediction for the limiting free energy per spin is correct for any positive temperature and external field. Further, local marginals can be approximated by iterating a set of mean field (cavity) equations. Both results are achieved by proving the local convergence of the Boltzmann distribution on the original graph to the Boltzmann distribution on the appropriate infinite random tree.

description: Intelligent reflecting surface (IRS) is being considered as a prospective candidate for next-generation wireless communication due to its ability to significantly improve coverage and spectral efficiency by controlling the propagation environment. One of the ways IRS increases spectral efficiency is by adjusting phase shifts to perform passive beamforming. In this letter, we integrate the concept of IRS-aided communication to the domain of multi-direction beamforming, whereby multiple receive antennas are selected to convey more information bits than existing spatial modulation (SM) techniques at any specific time. To complement this system, we also propose a successive signal detection (SSD) technique at the receiver. Numerical results show that the proposed design is able to improve the average successful bits transmitted (ASBT) by the system, which outperforms other state-of-the-art methods proposed in the literature.
