description: We synthesized a range of geographically-explicit forest, grassland and cropland biomass and soil carbon input data sources and used geographic information systems (GIS) software to calculate new estimates of soil and biomass carbon stocks for use with global economic models, particularly for the Global Trade and Analysis Project (GTAP). Our results quantify the average amount of carbon stored in soil and biomass in each of the 246 countries, stratified by agro-ecological zones (available in the accompanying spreadsheet). We also provide the data aggregated to the 134 regions defined for the GTAP 8.1 database both in spreadsheet form and in GTAPâ€™s native binary file format. Finally, we provide an add-on to FlexAgg2 program to further aggregate the 134 regions as desired. Our analysis makes substantial refinements to the estimates of carbon stocks used for modeling carbon emissions from indirect land use change. The spatial detail of our analysis is a major advantage over previous databases because it provides estimates tailored to the regions of interest and better accounts for the variation of carbon stocks across the landscape, and between wetland and non-wetland regions.
Mott insulator to superfluid transition of ultracold bosons in an optical lattice near a Feshbach resonance

description: We study the phase diagram of ultracold bosons in an optical lattice near a Feshbach resonance. Depending on the boson density, the strength of the optical lattice potential and the detuning from resonance, the ground state can be a Mott insulator, a superfluid phase with both an atomic and a molecular condensate, or a superfluid phase with only a molecular condensate. Mott insulator to superfluid transitions can be induced either by decreasing the strength of the optical lattice potential or by varying the detuning from the Feshbach resonance. Quite generally, we find that for a commensurate density the ground-state may undergo several insulator-superfluid or superfluid-insulator transitions as the magnetic field is varied through the resonance.

Strong-correlation effects in Born effective charges

description: Large values of Born effective charges are generally considered as reliable indicators of the genuine tendency of an insulator towards ferroelectric instability. However, these quantities can be very much influenced by strong electron correlation and metallic behavior, which are not exclusive properties of ferroelectric materials. In this paper we compare the Born effective charges of some prototypical ferroelectrics with those of magnetic, non-ferroelectric compounds using a novel, self-interaction free methodology that improves on the local-density approximation description of the electronic properties. We show that the inclusion of strong-correlation effects systermatically reduces the size of the Born effective charges and the electron localization lengths. Furthermore we give an interpretation of the Born effective charges in terms of band energy structure and orbital occupations which can be used as a guideline to rationalize their values in the general case.

description: Many Australians are requiring mental health care, including families, leading to long wait times in order to access support. Walk-in therapy reduces barriers to mental health support services by providing support at the time that families seek help. This paper presents a proof-of-concept study investigating the acceptability and short-term effectiveness of an online walk-in family therapy service, Walk-in Together (WIT). Part 1 of the paper describes the experiences of 44 family members from 22 families who presented to a public family therapy clinic for a virtual walk-in family therapy session. The session was conducted by a team of three experienced family therapists. Family members' experiences were sought pre-session, post-session, and at 6 weeks follow-up via survey and interview. Part 2 of the paper explores therapist perceptions (n = 7) of the WIT approach, through thematic analysis of semi-structured interview data. Post-session feedback showed 85% of family members found WIT to be helpful and 50% were optimistic about their future as a family after their WIT session. Six weeks post-session it was revealed that WIT supported planning for families in equipping them to move forward with 88% of family members reporting that they knew what to do after the session. All therapists uniformly experienced the model as offering a timely and beneficial service, suitable for diverse presentations and constellations of families. These preliminary results suggest the significant utility of this WIT intervention as a well-received and helpful service for families, who valued the easy access and rapid therapeutic response afforded by the online, walk-in delivery model. This proof-of-concept paper suggests the potential for further development and growth of WIT, as well as other mental health support services using a walk-in, telehealth model to meet the rising demand for therapeutic support for families in distress.

description: The Bethe roots describing the ground state energy of the integrable 1D model of interacting bosons with weakly repulsive two-body delta interactions are seen to satisfy the set of Richardson equations appearing in the strong coupling limit of an integrable BCS pairing model. The BCS model describes boson-boson interactions with zero centre of mass momentum of pairs. It follows that the Bethe roots of the weakly interacting boson model are given by the zeros of Laguerre polynomials. The ground state energy and the lowest excitation are obtained explicitly via the Bethe roots. A direct link has thus been established, in the context of integrable 1D models, between bosons interacting via weakly repulsive two-body delta-interactions and strongly interacting Cooper pairs of bosons.

description: The purpose of the agro-ecological zone emission factor model (AEZ-EF) is to estimate the total CO2-equivalent emissions from land use changes, e.g., from an analysis of biofuels impacts or policy analyses such as estimating the effect of changes in agricultural productivity on emissions from land use. The model combines matrices of carbon fluxes (Mg CO2/ha/y) with matrices of changes in land use (ha) according to land-use category as projected by GTAP or similar AEZ-oriented models. As published, AEZ-EF aggregates the carbon flows to the same 19 regions and 18 AEZs used by GTAP-BIO, the version of GTAP currently used by Purdue University researchers for modeling biofuel-induced ("indirect") land-use change (ILUC) (e.g., Tyner, Taheripour et al. 2010). The AEZ-EF model, however, is designed to work with an arbitrary number of regions, as described in the accompanying report.

description: The EU Single Farm Payment (SFP) is currently distributed in proportion to primary factor shares in version 8 of the GTAP database. In this paper, we investigate whether this way of modeling the EU SFP makes a difference in analyzing agricultural policy reforms. To do so, we create alternative versions of the GTAP database to compare the effects with the default setting in GTAP. Employing OECD data, along with the GTAP framework, we vary the assumptions about the allocation of the SFP. In the process, we demonstrate how to alter and update the GTAP database to implement domestic support of OECD PSE tables. We provide a detailed overview supplemented with assumptions of payment allocation, shock calculations and in particular, the Altertax procedure to update value flows and price equations extended in the GTAP model. Subsequently, we illustrate the impact of those assumptions by simulating a 100% removal of the SFP using the deviating versions of GTAP database. This sensitivity analysis reveals strong differences in results, but particularly in production responses of food and agricultural sectors that decrease with an increasing degree of decoupling. Furthermore, our analysis shows that the effect on welfare and the trade balance decreases with an increasing degree of decoupling. This experiment shows that the allocation of the SFP can have strong impacts on simulation results.

description: A newly developed demand system is used to estimate the response of food and food product demand to per capita expenditure changes. The resulting Engel elasticities are then used to project food and food product demand in 2020 assuming per capita expenditure and population changes. Results suggest that while food expenditure is projected to grow, it accounts for a smaller proportion of total expenditure. Further analysis indicates change in the composition of food demand away from a grain and towards livestock is projected to occur in lower income countries in 2020.
The role of quality early childhood programs in supporting long-term integration of immigrant children and their families

description: When immigrant families and their children leave their country of origin to live in Canada, they experience a variety of challenges. Many of these challenges can place immigrant children at risk of developmental delay and lower educational achievement. While research suggests that immigrant children and their families benefit from participation in high quality centre-based early childhood programs, there are a variety of barriers that affect immigrant children’s participation in early childhood programs. Immigrant children are less likely to be enrolled in centre-based early childhood programs compared to native children. Early identification of the barriers to participation can help early childhood educators acquire a better understanding of immigrant families’ life circumstances so that they are better able to support immigrant children and their families.
Second-order effects of the magnetic vector potential in the Aharonov-Bohm experiment

Year: 2019
Subjects: subject: Classical Physics (physics.class-ph)

description: Recent experiments with the Aharonov-Bohm geometry have shown that, in addition to an electron-interference fringe shift, there is also a lateral displacement of the electron diffraction envelope. In this paper, we derive a displacement force based on a second-order expansion of the magnetic vector potential. The analysis illustrates the conservation of canonical angular momentum, where the mechanical angular momentum and field angular momentum sum to a constant of the motion; the azimuthal force required to change the mechanical momentum is thus supplied by changes in field momentum associated with the second-order vector potential term. Our results are consistent with all known Aharonov-Bohm experiments, including interference fringe shifts, lateral displacement forces, and the absence of longitudinal forces.

description: This master thesis applies the Network Theory to the analysis of transportation networks based on the three most basic types of transportation: airline, railway, and bus network. The nodes will represent the most prominent cities of Europe, as edges the available route between nodes and as weight the average cost of each route and the estimated duration of travel. The centralities measure of networks can help to identify the most important airports/railway and bus stations. Moreover, entropy of each centrality can detect if the values of each centrality is diversified and the vertex entropy assesses the diversification of the weight. Centralizations can help to understand if in these networks exist a dominant node.

description: The purpose of this thesis is to measure customer satisfaction for the company "Paterakis Bakery Products." The research was conducted in two stages: initially, data were collected from the company's customers through the distribution of a specially designed questionnaire. In the second stage, the collected data were analyzed using the MUSA (Multicriteria Satisfaction Analysis) method. The results derived from this method indicate customer satisfaction both overall and across individual criteria, thereby helping the company identify areas of high satisfaction as well as those where it underperforms. Consequently, the company was provided with the opportunity to pinpoint areas of weakness and focus on further improvements aimed at increasing the overall level of customer satisfaction.

description: Aberrant expression of the proto-oncogene BCL6 is a driver of tumorigenesis in diffuse large B cell lymphoma (DLBCL). Mice overexpressing BCL6 from the B cell-specific immunoglobulin heavy chain μ intron promoter (Iμ-Bcl6Tg/+) develop B cell lymphomas with features typical of human DLBCL. While the development of B cell lymphoma in these mice is tightly controlled by T cells, the mechanisms of this immune surveillance are poorly understood. Here we show that CD4 T cells contribute to the control of lymphoproliferative disease in lymphoma-prone Iμ-Bcl6Tg/+ mice. We reveal that this CD4 T cell immuno-surveillance requires signaling by the co-stimulatory molecule CD137 ligand (CD137L; also known as 4-1BBL), which may promote the transition of pre-malignant B cells with an activated phenotype into the germinal center stage via reverse signaling, preventing their hazardous accumulation. Thus, CD137L-mediated CD4 T cell immuno-surveillance adds another layer of protection against B cell malignancy to that provided by CD8 T cell cytotoxicity.

description: Formation of multi-solitons and vortex bright solitons in Bose-condensed alkali-metal atoms is analyzed by using the nonpolynomial Schordinger equation. A train of bright solitons is obtained from an axially homogeneous Bose-Einstein condensate by a sudden change of the scattering length from repulsive to attractive. We derive an analytical expression for the number of bright solitons generated by using this mechanism. The formula generalizes a previous formula obtained with the 1D Gross-Pitaevskii equation. In the second part we consider vortex bright solitons, namely cigar-shaped bright solitons with a nonzero angular quantum number $k$ along the axial direction. By using a variational approach we determine the shape of vortex bright solitons, showing that the critical number of atoms for the collapse of the vortex soliton increases with a larger $k$. Finally we calculate monopole and quadrupole collective oscillations of these vortex bright solitons.

description: Quantum-mechanical phenomena are playing an increasing role in information processing, as transistor sizes approach the nanometer level, and quantum circuits and data encoding methods appear in the securest forms of communication. Simulating such phenomena efficiently is exceedingly difficult because of the vast size of the quantum state space involved. A major complication is caused by errors (noise) due to unwanted interactions between the quantum states and the environment. Consequently, simulating quantum circuits and their associated errors using the density matrix representation is potentially significant in many applications, but is well beyond the computational abilities of most classical simulation techniques in both time and memory resources. The size of a density matrix grows exponentially with the number of qubits simulated, rendering array-based simulation techniques that explicitly store the density matrix intractable. In this work, we propose a new technique aimed at efficiently simulating quantum circuits that are subject to errors. In particular, we describe new graph-based algorithms implemented in the simulator QuIDDPro/D. While previously reported graph-based simulators operate in terms of the state-vector representation, these new algorithms use the density matrix representation. To gauge the improvements offered by QuIDDPro/D, we compare its simulation performance with an optimized array-based simulator called QCSim. Empirical results, generated by both simulators on a set of quantum circuit benchmarks involving error correction, reversible logic, communication, and quantum search, show that the graph-based approach far outperforms the array-based approach.

description: Graphene is a two-dimensional layer of carbon atoms arranged in a honeycomb lattice, whose outstanding properties makes it an excellent material for future electronic and photonic terahertz (THz) devices. In this work, we design hybrid graphene metasurfaces by using a monolayer graphene placed over a metallic grating, operating in the THz frequency range. Perfect absorption can be achieved at the resonance, where the electric field is greatly enhanced due to the coupling between the graphene and the grating plasmonic responses. The enhancement of the electric field along the graphene monolayer, as well as the large nonlinear conductivity of graphene, can dramatically boost the nonlinear response of the proposed THz device. In addition, the presented enhanced nonlinear effects can be significantly tuned by varying the doping level of graphene. The proposed structure can be used in the design of THz-frequency generators and all-optical processors.

description: The low-energy excitations of Cr, i.e. the Fincher-Burke (FB) modes, have been investigated in the transversely polarized spin-density-wave phase by inelastic neutron scattering using a single-(Q+-) crystal with a propagation vector (Q+-) parallel to [0,0,1]. The constant-momentum-transfer scans show that the energy spectra consist of two components, namely dispersive FB modes and an almost energy-independent cross section. Most remarkably, we find that the spectrum of the FB modes exhibits one peak at 140 K near Q = (0,0,0.98) and two peaks near Q = (0,0,1.02), respectively. This is surprising because Cr crystallizes in a centro-symmetric bcc structure. The asymmetry of those energy spectra decreases with increasing temperature. In addition, the observed magnetic peak intensity is independent of Q suggesting a transfer of spectral-weight between the upper and lower FB modes. The energy-independent cross section is localized only between the incommensurate peaks and develops rapidly with increasing temperature.

description: The Wilsonian renormalization group (RG) properties of the conformal factor of the metric are profoundly altered by the fact that it has a wrong-sign kinetic term. The result is a novel perturbative continuum limit for quantum gravity, which is however non-perturbative in $\hbar$. The ultraviolet part of the renormalized trajectory lies outside the diffeomorphism invariant subspace, entering this subspace only in the infrared, below a dynamically generated amplitude suppression scale. Interactions are dressed with coefficient functions of the conformal factor, their form being determined by the RG. In the ultraviolet, the coefficient functions are parametrised by an infinite number of underlying couplings. Choosing these couplings appropriately, the coefficient functions trivialise on entering the diffeomorphism invariant subspace. Here, dynamically generated effective diffeomorphism couplings emerge, including Newton's constant. In terms of the Legendre effective action, we establish the continuum limit to first order, characterising the most general form of such coefficient functions so as to verify universality.

description: This thesis argues for the importance of ritual and analyzes its use in Seneca’s Medea, emphasizing Act 4’s importance and its relevance for understanding Medea’s actions and identity in Act 5. I employ the ritual methodologies of Catherine Bell and Bruce Kapferer, and broader context of Roman religion, to argue that Medea uses ritual to transform herself, culminating in sacrificial murders which make her a divinity, escaping the mortal realm by the end of the play. Focusing first on prayer, I exhibit how it structures the mortal’s position with respect to divinities according to a recognizably ‘lived’ experience of its first century CE audience. Subsequently, I show how the magic ritual of Act 4 portrays Medea as a powerful sorceress and actively stages ritual to augment her existing power, entering her into the divine realm. I emphasize her divine heritage and special bond with Hecate as crucial factors to her success. Lastly, I posit that the child-murders of Act 5 function as a sacrifice that re-integrates Medea with her birth family, severs her from mortal community, and designates her as a vengeful deity. I build upon Senecan scholarship by suggesting a progressive arc for the play and treating ritual seriously. My work faces ritual as lived experience, one demanding the full engagement of the participant’s mind and matter. Contextualizing within Roman religion, I explore how ritual functions as a communication method between humans and gods. This ritual analysis also illuminates the interconnectedness of magic and public cult, casting doubt on the dominant assumption that any ritual performed in isolation is magical. Furthermore, I analyze the sacrificial murders to comment on perversion in Roman religion. I thus show the play’s embeddedness in early Imperial Rome’s culture and indicate that Seneca uses this to speak to the terrifying concept of abusing power.

description: The tracer equations are part of the primitive equations used in ocean modeling and describe the transport of tracers, such as temperature, salinity or chemicals, in the ocean. Depending on the number of tracers considered, several equations may be added to and coupled to the dynamics system. In many relevant situations, the time-step requirements of explicit methods imposed by the transport and mixing in the vertical direction are more restrictive than those for the horizontal, and this may cause the need to use very small time steps if a fully explicit method is employed. To overcome this issue, we propose an exponential time differencing (ETD) solver where the vertical terms (transport and diffusion) are treated with a matrix exponential, whereas the horizontal terms are dealt with in an explicit way. We investigate numerically the computational speed-ups that can be obtained over other semi-implicit methods, and we analyze the advantages of the method in the case of multiple tracers.

description: The virtual ant introduced by C. Langton has an interesting behavior, which has been studied in several contexts. Here we give a construction to calculate any boolean circuit with the trajectory of a single ant. This proves the P-hardness of the system and implies, through the simulation of one dimensional cellular automata and Turing machines, the universality of the ant and the undecidability of some problems associated to it.

Gravitational quasinormal radiation of higher-dimensional black holes

description: We find the gravitational resonance (quasinormal) modes of the higher dimensional Schwarzschild and Reissner-Nordstrem black holes. The effect on the quasinormal behavior due to the presence of the $λ$ term is investigated. The QN spectrum is totally different for different signs of $λ$. In more than four dimensions there excited three types of gravitational modes: scalar, vector, and tensor. They produce three different quasinormal spectra, thus the isospectrality between scalar and vector perturbations, which takes place for D=4 Schwarzschild and Schwarzschild-de-Sitter black holes, is broken in higher dimensions. That is the scalar-type gravitational perturbations, connected with deformations of the black hole horizon, which damp most slowly and therefore dominate during late time of the black hole ringing.

Identifying and Addressing Accessibility Priorities: An Ongoing Institutional Process

description: The University of British Columbia has been progressively working for at least two decades towards access improvement projects on campus. The recent Campus Plan (2010), which incorporates Universal Design Principles into all new construction and renovation projects, in conjunction with hosting the 2010 Paralympics, ushered in a “new era” with a clear focus on continued enhancement of accessibility at UBC. Since then, there has been significant improvement in the public realm as well as in buildings to, for example, provide multiple accessible route options to people with physical disabilities. A decentralized University structure has allowed for heightened awareness and has increased the profile of issues related to accessibility on campus. The biggest barrier to addressing existing deficiencies is a lack of adequate funding to make improvements. However, staff have been very creative in leveraging opportunities whenever they arise. Since a number of accessibility deficiencies continue to exist, it would be useful to have a way of communicating out the progress that has been made and any future plans for addressing outstanding issues. It would also be valuable to have a structured way for members of the university community to relay information about accessibility deficiencies as they arise. Temporary barriers, such as construction, and temporary disabilities pose specific challenges that should also be addressed through improved communication and education. This builds upon the recent decentralization of facilities management, which has improved relationships with building users. Overall, university staff have been creative in moving forward with the accessibility improvements in light of a tight fiscal environment.

description: Using the non-Abelian action for coincident Type IIB gravitational waves proposed in hep-th/0303183 we show that giant gravitons in the AdS_3 x S^3 x T^4 background can be described in terms of coincident waves expanding into a fuzzy cylinder, spanned by two embedding scalars and one worldvolume scalar. This fuzzy cylinder has dipole and magnetic moments with respect to the 2-form and 6-form potentials of the background, and can be interpreted as a bound state of D1-branes and D5-branes (wrapped on the 4-torus) wrapped around the basis of the cylinder. We show the exact agreement between this description and the Abelian, macroscopical description given in the literature.

Type III CRISPR systems

description: CRISPR-Cas systems offer prokaryotes an adaptive defence mechanism, allowing them to respond to the invading nucleic acids. Type III CRISPR systems feature the capacity of synthesising cyclic oligoadenylate (cOA) species, which serve as second messengers to activate ancillary effectors, enhancing immune response. A diverse array of ancillary proteins is predicted to participate in cOA-mediated signalling for immunity enhancement. Nevertheless, the specific functions of many of these ancillary effectors have remained elusive. Here we have unravelled the workings of two novel type III-B CRISPR systems. The first system, from the human gut bacteria Bacteroides fragilis (BfrCmr), associates with an uncharacterised CorA family membrane protein and a NrN family phosphodiesterase. BfrCmr provides defence against mobile genetic elements when expressed in the heterologous host E. coli. A remarkable discovery was the identification of a novel signal molecule, S-adenosyl methionine (SAM)-AMP by conjugating ATP to SAM through a phosphodiester bond, when the BfrCmr system was activated. SAM-AMP in turn binds to the membrane protein CorA, presumably leading to membrane disruption and ultimately cell death. The cognate phosphodiesterase NrN or SAM lyase from Clostridium botulinum degrades SAM-AMP, offering two different means of regulating the signalling pathway. The second type III CRISPR system investigated is associated with three ancillary proteins, including a Lon protease CalpL, extracytoplasmic function sigma factor CalpS and a toxin MazF homologue CalpT. CalpL consist of a SAVED sensor domain fused with a Lon protease effector domain. CalpL forms a tripartite complex with CalpS and CalpT. When SAVED domain bound to activator cA4, CalpL oligomerises and specifically cleaves CalpT, resulting in the release of the sigma factor CalpS from the complex. This identification of a SAVED domain-containing protease that responses to cOA and triggers the transcriptional regulation provides insights into the sophisticated multi-layered defence mechanisms characterised in type III CRISPR signal-mediated immunity.

description: We study the zero-temperature dynamic transition from the disordered flow to an ordered flow state in driven vortices in type-II superconductors. The transition current $I_{p}$ is marked by a sharp kink in the $V(I)$ characteristic with a concomitant large increase in the defect concentration. On increasing magnetic field $B$, the $I_{p}(B)$ follows the behaviour of the critical current $I_{c}(B)$. Specifically, in the peak effect regime $I_{p}(B)$ increases rapidly along with $I_{c}$. We also discuss the effect of varying disorder strength on $I_{p}$.
