description: We consider the adiabatic evolution of the Dirac equation in order to compute its Berry curvature in momentum space. It is found that the position operator acquires an anomalous contribution due to the non Abelian Berry gauge connection making the quantum mechanic algebra noncommutative. A generalization to any known spinning particles is possible by using the Bargmann-Wigner equation of motions. The noncommutativity of the coordinates is responsible of the topological spin transport of spinning particle similarly to the spin Hall effect in spintronic physics or the Magnus effect in optics. As an application we predict new dynamics for nonrelativistic particles in an electric field and for photons in a gravitational field.

description: University Hill Secondary School (UHSS), located in Vancouver, British Columbia, will be moving to a new building near the UBC Farm. The UBC Farm is a research and educational facility located on UBC campus. This report aims to help the UHSS Home Economics teacher, Ellen Walker, reconnect her students with food, ecological systems, and the environment through new curriculum ideas for her Home Economics classes that utilize the resources of the UBC Farm. This project began with a primary literature review followed by the decision to focus on a ‘fall’ theme in order to collaborate with a second LFS group assigned to this project. We met with our stakeholders: the Land and Food System (LFS) teaching team, Ellen Walker and the students of UHSS, and Mark Bomford of the UBC Farm. The result of this project was three lesson plans (topics: chickens and eggs, apples, and pumpkins) which address the knowledge disconnect between farm and plate, tie into Ms. Walker’s existing lesson plans, and outline the many of BC Ministry of Education’s Prescribed Learning Outcomes given for grades 10-12 that they meet. Through our adapted lesson plans, students will acquire a greater understanding of the food system as well as gain hands-on learning opportunities at the UBC Farm. Three recommendations were given with clear and timely goals which aim to establish a lasting and meaningful connection between UHSS and the UBC Farm. First, we hope the connection is initiated with a minimum of two farm visits in the upcoming school year. We then hope UHSS encourages extracurricular student participation, and that future LFS student groups evaluate the progress to determine the success of and potential for expansion on these adapted lesson plans.

description: The interface of complex oxide heterostructures sets the stage for various electronic and magnetic phenomena. Many of these collective effects originate from the precise structural arrangement at the interface that in turn governs local spin- and charge interactions. Currently, interfacial straining, so the naturally evolving compressive or tensile strain by mismatch of the neighboring lattices, is the most common route towards engineering collective material properties -- yet, significant progress might require exploration of entirely new approaches towards interface correlations. In this work, we turn the page by looking at the interface of a perfectly relaxed, unstrained heterostructure, where we identify a highly ordered Moire lattice at an inherently disordered SrTiO$_3$ (STO) - LSAT interface. Using high-resolution reciprocal space mapping via synchrotron based X-Ray diffraction, we find long-ranged ordered supercells of 106/107 unit cells of STO/LSAT, caused by lattice relaxation through high-temperature annealing. Model calculations confirm the experimentally observed scattering phenomena, showing that cross-interfacial bonding is locally different at the Moire-overlap points. Notably, the presence of such super-ordered structures in the family of 2D electron gas systems sets the ideal conditions for Moire-motif tuned plasmonic responses and ferroelectric super-crystallinity and opens up the possibility to novel interface functionalities in these simple perovskites.

Inverse electromagnetic obstacle scattering problems with multi-frequency sparse backscattering far field data

description: This paper is dedicated to design a direct sampling method of inverse electromagnetic scattering problems, which uses multi-frequency sparse backscattering far field data for reconstructing the boundary of perfectly conducting obstacles. We show that a smallest strip containing the unknown object can be approximately determined by the multi-frequency backscattering far field data at two opposite observation directions. The proof is based on the Kirchhoff approximation and Fourier transform. Such a strip is then reconstructed by an indicator, which is the absolute value of an integral of the product of the data and some properly chosen function over the frequency interval. With the increase of the number of the backscattering data, the location and shape of the underlying object can be reconstructed. Numerical examples are conducted to show the validity and robustness of the proposed sampling method. The numerical examples also show that the concave part of the underlying object can be well reconstructed, and the different connected components of the underlying object can be well separated.

description: We use bosonization approach to investigate quantum phases in mixtures of bosonic and fermionic atoms confined in one dimensional optical lattices. The phase diagrams can be well understood in terms of polarons, which correspond to atoms that are "dressed" by screening clouds of the other atom species. For a mixture of single species of fermionic and bosonic atoms we find a charge density wave phase, a phase with fermion pairing, and a regime of phase separation. For a mixture of two species of fermionic atoms and one species of bosonic atoms we obtain spin and charge density wave phases, a Wigner crystal phase, singlet and triplet paired states of fermions, and a phase separation regime. Equivalence between the Luttinger liquid description of polarons and the canonical polaron transformation is established and the techniques to detect the resulting quantum phases are discussed.

description: We report results from a spectral and timing analysis of M82 X-1, one of the brightest known ultraluminous X-ray sources. Data from a new 105 ks {\it XMM-Newton} observation of M82 X-1, performed in April 2004, and of archival {\it RossiXTE} observations are presented. A very soft thermal component is present in the {\it XMM} spectrum. Although it is not possible to rule out a residual contamination from the host galaxy, modelling it with a standard accretion disk would imply a black hole mass of $\approx 10^3 M_{\odot}$. An emission line was also detected at an energy typical for fluorescent Fe emission. The power density spectrum of the {\it XMM} observation shows a variable QPO at frequency of 113 mHz with properties similar to that discovered by Strohmayer & Mushotzky (2003). The QPO was also found in 7 archival {\it RXTE} observations, that include those analyzed by Strohmayer & Mushotzky (2003) and Fiorito & Titarchuk (2004). A comparison of the properties of this QPO with those of the various types of QPOs observed in Galactic black hole candidates strongly suggests an association with the type-C, low frequency QPOs. Scaling the frequency inversely to the black hole mass, the observed QPO frequency range (from 50 to 166 mHz) would yield a black hole mass anywhere in the interval few tens to 1000 $M_\odot$.

description: Strongly correlated systems are often associated with an underlying quantum critical point which governs their behavior in the finite temperature phase diagram. Their thermodynamical and transport properties arise from critical fluctuations and follow universal scaling laws. Here, we develop a microscopic theory of thermal transport in the quantum critical regime expressed in terms of a thermal sum rule and an effective scattering time. We explicitly compute the characteristic scaling functions in a quantum critical model system, the unitary Fermi gas. Moreover, we derive an exact thermal sum rule for heat and energy currents and evaluate it numerically using the nonperturbative Luttinger-Ward approach. For the thermal scattering times we find a simple quantum critical scaling form. Together, the sum rule and the scattering time determine the heat conductivity, thermal diffusivity, Prandtl number and sound diffusivity from high temperatures down into the quantum critical regime. The results provide a quantitative description of recent sound attenuation measurements in ultracold Fermi gases.

description: We show that the RST model describing the exactly soluble black hole model can have a dynamical wormhole solution along with an appropriate boundary condition. The necessary exotic matter which is usually negative energy density is remarkably produced by the quantization of the infalling matter fields. Then the asymptotic geometry in the past is two-dimensional anti-de Sitter(AdS$_2$), which implies the exotic matter is negative. As time goes on, the wormhole eventually evolves into the black hole and its Hawking radiation appears. The throat of the static RST wormhole is lower-bounded but in the presence of infalling matter it collapses to a black hole.

description: We propose a platform for robust and tunable nonreciprocal phonon transport based on arrays of optomechanical microtoroids. In our approach, time-reversal symmetry is broken by the interplay of photonic spin-orbit coupling, engineered using a state-of-the-art geometrical approach, and the optomechanical interaction. We demonstrate the topologically protected nature of this system by investigating its robustness to imperfections. This type of system could find application in phonon-based information storage and signal processing devices.

description: We extract the long-range gravitational potential between two scalar particles with arbitrary masses from the two-to-two elastic scattering amplitude at 2nd Post-Minkowskian order in arbitrary dimensions. In contrast to the four-dimensional case, in higher dimensions the classical potential receives contributions from box topologies. Moreover, the kinematical relation between momentum and position on the classical trajectory contains a new term which is quadratic in the tree-level amplitude. A precise interplay between this new relation and the formula for the scattering angle ensures that the latter is still linear in the classical part of the scattering amplitude, to this order, matching an earlier calculation in the eikonal approach. We point out that both the eikonal exponentiation and the reality of the potential to 2nd post-Minkowskian order can be seen as a consequence of unitarity. We finally present closed-form expressions for the scattering angle given by leading-order gravitational potentials for dimensions ranging from four to ten.

description: Using quantum Monte Carlo simulations, results of a strong-coupling expansion, and Luttinger liquid theory, we determine quantitatively the ground state phase diagram of the one-dimensional extended Hubbard model with on-site and nearest-neighbor repulsions U and V. We show that spin frustration stabilizes a bond-ordered (dimerized) state for U appr. V/2 up to U/t appr. 9, where t is the nearest-neighbor hopping. The transition from the dimerized state to the staggered charge-density-wave state for large V/U is continuous for U up to appr. 5.5 and first-order for higher U.

The ways of referential deficiency: Impersonal on and its kin
Creators: name: Rezac, Milan
name: Jouitteau, Mélanie
Publisher: name: Zenodo
Year: 2016

description: This work is a study of the French impersonal on and a theory of the unique "referential deficiency" of impersonals: a range of uses that spans those covered by indefinites and definites; neutrality about content like number; systematic participation in syntactic and semantic dependencies but with unparalleled restrictions like binding of only local, number-neutral anaphora. Current understanding of the syntax and semantics of DPs and properties of French let us study this behavior in depth and extend previous findings, often in unexpected ways. The study reveals a DP with content unique in French but drawing only on options available in UG. It leads to a theory of impersonal on as an indefinite DP whose content interacts with certain theories of phi-features, indefinites and definites, and anaphoric dependencies to give an explanatory account of the nature of impersonals. In turn, impersonal on contributes to the theories that enter into its analysis: the relationship between syntactic underspecification and semantic neutrality, the nature of indefinites and their relationship to definites (Heim 1991, 2011; Heim 1982, Elbourne 2013), and minimal pronoun anaphora (Kratzer 2009). The study is extended to the grammaticalisation of a distinct 1PL on, whose complex properties reflect the colexicalisation of impersonal on and a 1PL element. We end the book on the place of impersonals in the landscape of argument coding and explore the expected parameter space through on-like impersonals cross-linguistically. The work builds on the analysis of on and its kin in Cinque (1988), Chierchia (1995b), Egerland (2003b), Kayne (2010), and explores them in the Principles-and-Parameters approach to syntax and the "situated descriptions" (Elbourne 2013) extension of the syntax-semantics mapping of Heim and Kratzer (1998).

description: We investigate the linearized gravity on a single de Sitter brane in the anti-de Sitter (AdS) bulk in the Einstein Gauss-Bonnet (EGB) theory. We find that the Einstein gravity is recovered for a high energy brane, i.e., in the limit of the large expansion rate, $H\ell\gg 1$, where $H$ is the de Sitter expansion rate and $\ell$ is the curvature radius of the AdS bulk. We also show that, in the short distance limit $r\ll \min\{\ell,H^{-1}\}$, the Brans-Dicke gravity is obtained, whereas in the large distance limit $r\gg\max\{\ell,H^{-1}\}$, the Brans-Dicke gravity is obtained for $H\ell=O(1)$, and the Einstein gravity is recovered both for $H\ell\gg1$ and $H\ell\ll1$. In the limit $H\ell\to0$, these results smoothly match to the results known for the Minkowski brane.

Argumental null subjects in Old Icelandic
Creators: name: Rezac, Milan
Publisher: name: Zenodo
Year: 2017

description: This work presents a study of argumental null subjects in Old Icelandic (OIc) that leads to a partly new picture of human impersonals and 3rd person referential pro in the language and of their theoretical consequence. OIc human impersonals have the profile of generic impersonal pronouns crosslinguistically, with formal counterparts in the generic pro of Modern Icelandic and Finnish, but different distribution and usage that contribute to understanding this impersonal class. Of particular interest are apparently nongeneric and specific uses, both of which affect the study of referential pro. OIc referential pro has been a focus of theoretical interest because of its unusual rarity and contested formal restrictions. These findings are confirmed globally, but a different picture emerges on a more fine-grained study relativised to antecedent and dependency types. Global rarity is punctuated by islands where pro is either the rule or on par with overt pronouns. Some are theoretically distinct subsystems of restricted pro-drop such as pro for reference to weapons, while others like quantifier-bound pro contribute to understanding the major pro-drop system of the language. Characteristics of the major system – preference of quantifiers for pro, availability of low-topicality antecedents, limits on nonexhaustive antecedence, and role of cohesion – suggest that it fits best in the "cohesive" pro-drop type emerging from work on 3rd person pro in Hebrew and Finnish. Throughout emphasis is placed on issues that restrictions on null subjects raise for theories of conventionalisation, such as parameter theory, which are discussed in synchronic and diachronic perspectives.

description: The evaluation of Yukawa-enhanced two-loop contributions to the MSSM Higgs-boson mass is considered. We prove the common assumption that regularization by dimensional reduction preserves supersymmetry at the required level. Thus generating counterterms by multiplicative renormalization is correct. Technically, we identify a suitable Slavnov-Taylor identity, use a recently developed method to evaluate it at the two-loop level, and show that it is valid in dimensional reduction.

description: A new lanthanide metal-organic framework (MOF), {[Eu2(BPS)3(H2O)4]·18(H2O)}n (1) with a wavy infinite chain secondary unit, has been prepared via utilizing 4,4′-bibenzoic acid-2,2′-sulfone (H2BPS) as the ligand under solvothermal conditions and characterized via single crystal X-ray diffraction, element analysis, TGA and PXRD. Due to its good water stability and strong emission under UV irradiation at room temperature, 1 could be used as a luminescent probe for acetone molecules. Furthermore, the inhibitory effect of 1 against bacteria was explored. The inhibitory effects of 1 on gram positive and negative bacteria cells were detected by RT-PCR. ELISA was performed to evaluate the IL-1β and TNF-α in the plasma.

TYPE LOCALITY AND TYPE REPOSITORY. Bhopal, now Madhya Pradesh, India; BMNH.
TYPE MATERIAL EXAMINED. Burma, leg. H. M. Phipson, 1♀ (holotype), BMNH No. 1893.12.20.4.
 OTHER MATERIAL EXAMINED. India, Maharashtra State, Bhimashankar, 19º4'N, 73º32'E, 1–2.II.1990, 2♀, leg. V. & B. Roth, CASC; Maharashtra State, Dhasai env., II.1998, 2♀ leg. P. Rojek, FKCP; Rajasthan State, Mt. Abu, II.1998, 1♂, leg. P. Rojek, FKCP.
DISTRIBUTION. India (Madhya Pradesh) (Pocock, 1897b: 114) (Maharashtra) (first record) (Rajasthan) (first record).
COMMENTS. Pocock (1897b: 114) does not mention the sex of the type and gives the type locality as “Bhopal, Central India (Surgn.-Lieut.-Col. Dane)“. Tikader & Bastawade (1983: 266) say the type is a female No. 1893.12.20.4. Fet & Lowe (2000: 153) give the type locality as “Bhopal, now Madhya Pradesh, India “ and list the holotype as a male No. 1893.12.20.4. I examined the type and found it to be a female with two labels: (1) “1893.12.20.4., Isometrus rigidulus Poc., TYPE, Burma, H. M. Phipson“, and (2) “ Isometrus (Reddyanus) rigidulus Pocock 1897 Spécimen examiné en 1972 par Max Vachon“. There can be no doubt that it is the holotype, but the difference in label and original description makes its locality doubtful.
 Examination of an adult male reveals the sexual dimorphism of this species to be less obvious than in other species of the subgenus Reddyanus. The manus of pedipalps is of the same width in both sexes. The male has slightly narrower and longer metasomal segments, and the terminal tubercle of each dorsal carina is more enlarged on the third than on the second metasomal segment. In the female the terminal tubercle enlargement is to a lesser degree apparent on the third segment and is absent on the second segment.

description: The World Bank (2015) reports that, in 2014, almost 1.9 billion individuals in the developing world – roughly one-third of the population in these countries – benefitted from social protection programmes. This is disproportionately driven by the size of the programmes in large countries such as China and India. The World Bank estimates that nearly one-third of individuals in the developing world receive benefits from a social protection programme. This compares favourably with the estimated average coverage rate of 25.0 per cent in SSA. The latter suggests that approximately 250 million individuals in SSA are beneficiaries of some form of social protection programme, almost equivalent to the number of beneficiaries of India’s National Rural Employment Guarantee Act (NREGA).

description: In the high-Tc cuprates, the unusual dependence of Tc on external pressure results from the combination of the nonmonotonic dependence of Tc on hole doping or hole-doping distribution among inequivalent layers, and from an ``intrinsic'' contribution. After reviewing our work on the interplay among Tc, hole content, and pressure in the bilayered and multilayered cuprate superconductors, we will discuss how the proximity to an electronic topological transition (ETT) may give a microscopic justification of the ``intrinsic'' pressure dependence of Tc in the cuprates. As a function of the proximity to an ETT, we recover a nonmonotonic behaviour of the superconducting gap at T=0, regardless of the pairing symmetry of the order parameter. This is in agreement with the trend observed for Tc as a function of pressure and other material specific quantities in several high-Tc cuprates. In the case of epitaxially strained cuprate thin films, we argue that an ETT can be driven by a strain-induced modification of the in-plane band structure, at constant hole content, at variance with a doping-induced ETT, as is usually assumed. We also find that an increase of the in-plane anisotropy enhances the effect of fluctuations above Tc on the normal-state transport properties, which is a fingerprint of quantum criticality at T=0.

description: Sub-Saharan Africa (SSA) has witnessed impressive progress on human development over the past 25 years. Indeed, using the Human Development Index (HDI) as a measure of development, since 2000, SSA has experienced more rapid growth than any other region, growing at 1.68 per cent from 2000 to 2010 and 0.94 per cent from 2010 to 2014 (UNDP, 2015a). The rate of progress in some countries – for example, Rwanda, Ethiopia and Mozambique – has been particularly remarkable.

description: The three-dimensional organization of chromatin, on the length scale of a few genes, is crucial in determining the functional state - accessibility and the amount of gene expression - of the chromatin. Recent advances in chromosome conformation capture experiments provide partial information on the chromatin organization in a cell population, namely the contact count between any segment pairs, but not on the interaction strength that leads to these contact counts. However, given the contact matrix, determining the complete 3D organization of the whole chromatin polymer is an inverse problem. In the present work, a novel Inverse Brownian Dynamics (IBD) method based on a coarse grained bead-spring chain model has been proposed to compute the optimal interaction strengths between different segments of chromatin such that the experimentally measured contact count probability constraints are satisfied. Applying this method to the α-globin gene locus in two different cell types, we predict the 3D organizations corresponding to active and repressed states of chromatin at the locus. We show that the average distance between any two segments of the region has a broad distribution and cannot be computed as a simple inverse relation based on the contact probability alone. The results presented for multiple normalization methods suggest that all measurable quantities may crucially depend on the nature of normalization. We argue that by experimentally measuring predicted quantities, one may infer the appropriate form of normalization.

description: Malawi is a small country located in Southern Africa. It has a surface area of 118,000 km2, a total length of 540 miles and a maximum width of 150 miles. The country is landlocked and the nearest harbours, Beira and Nacala (both located in Mozambique), are around 1,000 km from Lilongwe, Malawi’s capital. The country became a British colony in 1893 and gained independence in 1964. In 2011, the last year with inequality data, the total population was 15.5 million and its growth rate was around 3.0 per cent (UN DESA, Population Division, 2015). The population density is high, at 182.6 people per km2, against an average of 37 for sub-Saharan Africa (SSA). The mainstay of the economy is agriculture, which currently employs 65.0 per cent of the workforce and generates about 36.0 per cent of GDP and 90.0 per cent of foreign exchange earnings. This sector is characterised, historically, by the dualism between small subsistence farms versus large estates run by white settlers during colonial times and by domestic elites after independence.

title: Matrix Metalloproteinase Activation and Inhibition
Creators: name: O'Connell, James Philip
Publisher: name: The Open University
Year: 1995

description: Processes leading to the in vitro activation of progelatinase-A, progelatinase-B and procollagenase were examined. Progelatinase-A can be activated by treatment with 4-aminophenyl mercuric acetate or by matrilysin and collagenase. The former induces an intramolecular self-cleavage before further intermolecular cleavages generate the mature enzyme. Whilst matrilysin can process progelatinase-A to the mature form, collagenase can only generate an intermediate by cleaving after N37 in the bait region. This intermediate is identical to that produced by a human tumour cell-line in culture. Gelatinase-A reciprocates the action of collagenase by completing the activation of the latter to generate a form of collagenase with full collagenolytic activity. This has been described as superactivation and is commonly associated with the action of stromelysin. It correlates with the appearance of F81 at the amino-terminus.

 The C-terminal domain plays no role in catalysis but may be important for in vivo activity. This is particularly evident for collagenase which loses the ability to cleave collagen in its absence. The interaction between collagenase and collagen was shown to be a potential target for designing inhibitors of collagen breakdown.

 The properties of a series of reversible, competitive hydroxamic acid matrix metalloproteinase inhibitors were studied. Incorporation of a phenylpropyi group in the P1' position produced inhibitors with picomolar affinities for the gelatinases and discriminated against collagenase and matrilysin and other classes of zinc metallopeptidases. The high affinity of these inhibitors for gelatinase-A was shown to derive from a combination of diffusion limited association rates and very slow dissociation rates.

 Methods were developed to allow the study of the pharmacokinetic properties of these inhibitors. Chemical modifications at the P2’ and P3’ positions were shown to result in inhibitors with oral bioavailabilities of greater than 30% in the mouse.

On the (un)interpretability of phi-agreement
Creators: name: Rezac, Milan
Publisher: name: Zenodo
Year: 2016
Subjects: agreement, phi-features, semantics, syntax

description: Phi-features in agreement have usually been analysed as uninterpretable. This hypothesis is important evidence about the autonomy of syntax and about particular syntactic mechanisms. However, there are also interpretive approaches to phi-agreement. This study looks at potentials and challenges of interpretive proposals against known phi-agreement phenomena. First are taken up prototypical cases, such as local argument-predicate phi-agreement, and their natural extensions, such as phi-agreement under A'-movement. These cases are interpretable under independently motivated analyses of phi-features and syntactic structures. Long-distance phi-agreement is recalcitrant on its standard analysis, and an alternative is developed that attributes a key role to apparent expletives. Next are taken up more challenging phi-agreements: nonstandard target-controller pairs like objects agreeing with subjects; partial agreement in coordinate structures; and agreement with quantitative/qualitative controllers like a minority of jurors, the last with a case study of interpretive approaches through silent plurality/group denotation shifters. Last are discussed grammatical phi-features, which seem uninterpretable even on controllers. Available approaches are outlined and extended to agreement. The crosslinguistic variety of grammatical phi-agreement is emphasised, including heterogenous agreement patterns and constructional phi-features with missing controllers. The study suggests that independently motivated interpretations of phi-features and structures go far in interpreting phi-agreement but face a significant residue that requires unmotivated stipulations. Moreover, motivations of interpretability fail to replace syntactic conditions on agreement like person-hierarchy interactions. In the conclusion is surveyed evidence for interpreting phi-agreement, which is at present rather weak.

description: Our primary objective is to construct a plausible unified model of inflation, dark energy and dark matter from a fundamental Lagrangian action first principle, where all fundamental ingredients are systematically dynamically generated starting from a very simple model of modified gravity interacting with a single scalar field employing the formalism of non-Riemannian spacetime volume-elements. The non-Riemannian volume element in the initial scalar field action leads to a hidden nonlinear Noether symmetry which produces energy-momentum tensor identified as a sum of a dynamically generated cosmological constant and a dust-like dark matter. The non-Riemannian volume-element in the initial Einstein-Hilbert action upon passage to the physical Einstein-frame creates dynamically a second scalar field with a non-trivial inflationary potential and with an additional interaction with the dynamically generated dark matter. The resulting Einstein-frame action describes a fully dynamically generated inflationary model coupled to dark matter. Numerical results for observables such as the scalar power spectral index and the tensor-to-scalar ratio conform to the latest 2018 PLANCK data.

description: Ethiopia is a landlocked, multi-ethnic and ecologically diverse country of 1.1 million square kilometres, with a population of 99 million people growing at 2.5 per cent a year (UNDESA, 2015). The country occupies much of the Horn of Africa, a drought-prone area frequently affected by food crisis. Despite these structural handicaps, between 2000 and 2011, Ethiopia recorded GDP growth of 8.0 per cent, 6.0 per cent growth in agriculture, a rapid increase in cereal production, stable and low inequality, and declining poverty (table 13.1).
