description: The UBC farm is in need of buying a pickup truck to continue its daily operations, since the current one is quite old. UBC farm representative Véronik Campbell asked the APSC 261 students to carry out research on the best potential type truck that is currently on the market. This report presents a triple-bottom line assessment on some of the types of trucks that can be used. During the research 3 types of trucks have been of a particular interest: combustion engine with a biodiesel option, hybrid and electric. This report also considers using a truck from a car co-op. Taking into account the economical, environmental and social impacts, it was suggested that the best choice would be buying an electric truck (Might-E Truck) for UBC Farm. The economical impact analyses the price of a vehicle, fuel and maintenance costs. The environmental impact analysis highlights factors such as GHG emissions and air pollutions. The social impact mainly addresses the health issues due to the air pollution produced by the trucks.

description: Microwave resonators made from high-temperature superconducting (HTS) films are becoming increasingly commercially competitive in the market of modern communication technologies. However, unlike normal metals, the HTS device performance suffers from intrinsically nonlinear electrodynamics, resulting in harmonic generation and intermodulation (IM) distortion at all levels of circulating power. The dominant sources of IM response are believed to be inductive and localized in only small regions of the HTS film having the highest current densities J_RF(x,y). In our previous papers, examining microwave resonators of simple microstrip geometry, we have demonstrated that local nonlinearity imaging is possible with the technique of low temperature laser scanning microscopy (LTLSM) adapted to microwave experiments. Unique contrast due to IM current density J_IM(x,y) was generated by the IM imaging method. It was applied to display the regions showing large nonlinear LTLSM photoresponse (PR) in HTS devices with a few-micrometer spatial resolution. Direct local correlation between J_IM(x,y) and high J_RF(x,y) at the edges of the strips, typical defects like twindomain blocks, in-plane rotated grains and micro-cracks was shown. Here we want to indicate that the geometrical features in HTS circuit layout for microwave devices of more complex geometry also radically affect the linear device performance.

description: In this paper, we report the measurement of the energy flow, the cross section and the average inelasticity of forward neutrons (+ antineutrons) produced in $\sqrt{s} = 13$ TeV proton-proton collisions. These quantities are obtained from the inclusive differential production cross section, measured using the LHCf Arm2 detector at the CERN Large Hadron Collider. The measurements are performed in six pseudorapidity regions: three of them ($η> 10.75$, $8.99 < η< 9.21$ and $8.80 < η< 8.99$), albeit with smaller acceptance and larger uncertainties, were already published in a previous work, whereas the remaining three ($10.06 < η< 10.75$, $9.65 < η< 10.06$ and $8.65 < η< 8.80$) are presented here for the first time. The analysis was carried out using a data set acquired in June 2015 with a corresponding integrated luminosity of $\mathrm{0.194~nb^{-1}}$. Comparing the experimental measurements with the expectations of several hadronic interaction models used to simulate cosmic ray air showers, none of these generators resulted to have a satisfactory agreement in all the phase space selected for the analysis. The inclusive differential production cross section for $η> 10.75$ is not reproduced by any model, whereas the results still indicate a significant but less serious deviation at lower pseudorapidities. Depending on the pseudorapidity region, the generators showing the best overall agreement with data are either SIBYLL 2.3 or EPOS-LHC. Furthermore, apart from the most forward region, the derived energy flow and cross section distributions are best reproduced by EPOS-LHC. Finally, even if none of the models describe the elasticity distribution in a satisfactory way, the extracted average inelasticity is consistent with the QGSJET II-04 value, while most of the other generators give values that lie just outside the experimental uncertainties.

description: Tobacco use is detrimental to both oral and general health. However, the prevalence of tobacco use continues to rise especially among students. In this study, a descriptive cross-sectional research design was used to determine the level of awareness on the effects of tobacco use on oral health among undergraduates of Applied Biology and Biotechnology, Enugu State University of Science and Technology, (ESUT) Agbani Enugu State through a multistage random sampling technique.

Proportional stratified random technique was used to divide the students into 4 strata of year one, year two, year three and final year respectively. 40 undergraduates were randomly selected from each of the strata to make up a sample size of 160 undergraduates. The instrument for data collection was a structured questionnaire. The research hypothesis was tested using Z-test. It was discovered that the level of awareness on the effects of tobacco use among undergraduates of Applied Biology and Biotechnology, ESUT was significantly low (29.80%). Higher level of awareness was discovered amongst the male gender (17.88%). Final year students displayed the highest level of awareness (10.70%). The age range with the highest level of awareness was 26-30 (11.90%). The media was found to be the most common source of awareness for the students (39.38%). Nonetheless, only a small proportion of the students were found to use tobacco products.

It was recommended that regular oral health awareness program should be organized for the students in order to raise their level of awareness on the effects of tobacco use on oral health.

D 69, 094505 (2004)] for the energies and the charge (vector) and matter (scalar) distributions for S-wave states in a heavy-light meson, where the heavy quark is static and the light quark has a mass about that of the strange quark. We study the radial distributions of higher angular momentum states, namely P- and D-wave states. In nature the closest equivalent of this heavy-light system is the B_s meson. The calculation is carried out with dynamical fermions on a 16^3 times 32 lattice with a lattice spacing of about 0.10 fm generated with the non-perturbatively improved clover action. It is shown that several features of the energies and radial distributions are in qualitative agreement with what one expects from a simple one-body Dirac equation interpretation.

description: We report results of terahertz Faraday and Kerr rotation spectroscopy measurements on thin ﬁlms of Bi1−xSbx, an alloy system that exhibits a semimetal-to-topological-insulator transition as the Sb composition x increases. By using a single-shot time-domain terahertz spectroscopy setup combined with a table-top pulsed mini-coil magnet, we conducted measurements in magnetic ﬁelds up to 30 T, observing distinctly diﬀerent behaviors between semimetallic (x < 0.07) and topological insulator (x > 0.07) samples. Faraday and Kerr rotation spectra for the semimetallic ﬁlms showed a pronounced dip that blue-shifted with the magnetic ﬁeld, whereas spectra for the topological insulator ﬁlms were positive and featureless, increasing in amplitude with increasing magnetic ﬁeld and eventually saturating at high ﬁelds (>20 T). Ellipticity spectra for the semimetallic ﬁlms showed resonances, whereas the topological insulator ﬁlms showed no detectable ellipticity. To explain these observations, we developed a theoretical model based on realistic band parameters and the Kubo formula for calculating the optical conductivity of Landau-quantized charge carriers. Our calculations quantitatively reproduced all experimental features, establishing that the Faraday and Kerr signals in the semimetallic ﬁlms predominantly arise from bulk hole cyclotron resonances while the signals in the topological insulator ﬁlms represent combined eﬀects of surface carriers originating from multiple electron and hole pockets. These results demonstrate that the use of high magnetic ﬁelds in terahertz magnetopolarimetry, combined with detailed electronic structure and conductivity calculations, allows us to unambiguously identify and quantitatively determine unique contributions from diﬀerent species of carriers of topological and nontopological nature in Bi1−xSbx.

description: In the frame of an effective MSSM model without gaugino-mass unification at a grand unification (GUT) scale, we set a lower bound on the neutralino mass based on the new WMAP data on $Ω_{CDM}$. Our lower bound, $m_χ \gsim 6$ GeV, leaves much room for relic neutralinos significantly lighter than those commonly considered ($m_χ \gsim 50$ GeV). We prove that these light neutralinos may produce measurable effects in WIMP direct detection experiments of low energy threshold and large exposure.

description: Organic light-emitting diodes (OLEDs) have attracted a lot of attentions because of their high performance in display applications. Organic emitters are still being developed to improve efficiency, colour gamut and sustainability, and thermally activated delayed fluorescence (TADF) materials are widely regarded as one of the most promising next-generation OLED emitters. To date, green TADF emitters have been developed, and the corresponding OLEDs show high light-emitting efficiency and long operation lifetimes. However, the performance of red and blue TADF OLEDs still lag their green-emitting counterparts. For this reason, this work focuses on developing new red and deep-blue TADF materials. A group of red and blue TADF emitters were designed and synthesized. Their photophysical properties and electroluminescence performance were also studied. In addition, it was found that doping some of these new emitters into common host materials, such as 2,8-bis(diphenyl-phosphoryl)dibenzo[b,d]thiophene (PPT), 2,2',2"-(1,3,5-Benzinetriyl)-tris(1-phenyl-1-H-benzimidazole) (TPBi) or poly(methyl methacrylate) (PMMA), can lead to organic long-persistent luminescence (OLPL) lasting for thousands of seconds at room temperature. As traditional room-temperature OLPL materials are based on exciplex emitters, the new OLPL systems discovered here demonstrates that exciplex formation is not required for harvesting OLPL. This enables a wide range of host materials to be used including materials as simple as PMMA. Expanding this concept further, the author developed a method for large-scale PMMA-based OLPL sample fabrication to take full advantage of its low expense. This method gives thick (> 2 mm) and clear OLPL products, and all the required equipment is easily accessed in lab condition. Combining the flexible design of TADF emitters and mature PMMA industry, this work opens the ‘door’ of large-scale, colour tuneable and cost-efficient room-temperature OLPL materials. At the same time, the light-emitting properties and mechanism of these new OLPL emitters were studied, which provides a guideline for further OLPL emitter improvements.

description: The Verwey transition in magnetite (Fe3O4) is the ﬁrst metal-insulator transition ever observed [1] and involves a concomitant structural rear- rangement and charge-orbital ordering. Due to the complex interplay of these intertwined de- grees of freedom, a complete characterization of the low-temperature phase of magnetite and the mechanism driving the transition have long re- mained elusive. It was demonstrated in recent years that the fundamental building blocks of the charge-ordered structure are three-site small po- larons called trimerons [2]. However, electronic collective modes of this trimeron order have not been detected to date, and thus an understand- ing of the dynamics of the Verwey transition from an electronic point of view is still lack- ing. Here, we discover spectroscopic signatures of the low-energy electronic excitations of the trimeron network using terahertz light. By driv- ing these modes coherently with an ultrashort laser pulse, we reveal their critical softening and hence demonstrate their direct involvement in the Verwey transition. These ﬁndings represent the ﬁrst observation of soft modes in magnetite and shed new light on the cooperative mechanism at the origin of its exotic ground state.
An investigation into UBC Farm Sustainability College : what are the social, ecological and economic factors to consider when planning sustainable housing options?

description: UBC Farm emphasizes the importance of “down-to-earth” and “low-tech” sustainability philosophy. And, Véronik Campbell, the project stakeholder, emphasizes two essential factors for this UBC Farm Sustainability College Project: a housing option must have minimum environmental impact and must be able to create community involvement (Campbell, 2012). With these essential considerations, the research has thoroughly done. Due to limited academic resources, three commercial products representing today’s leading sustainable housing are presented in this report: m-ch, Dwelle and 4Treehouse. Then, a triple bottom line assessment has been performed to analyze each housing option. As stated in the project guideline, the sustainability college shall have single occupancy units and family occupancy units. Approximately, it should be able to occupy 75-100 residents. Since a single house of each option cannot satisfy the desired number of occupants, multiple of those houses will be applied during assessment. The definition of sustainability is very broad; no single housing option can fulfill the purposes. Thus, a combination of m-ch, dewell.ing, and 4Treehouse will be ultimately selected for UBC Farm Sustainability College project.

description: A string basis is constructed for each subalgebra of invariants of the function algebra on the quantum special linear group. By analyzing the string basis for a particular subalgebra of invariants, we obtain a ``canonical basis'' for every finite dimensional irreducible $U_q({\mathfrak{sl}}(n))$-module. It is also shown that the algebra of functions on any quantum homogeneous space is generated by quantum minors.

Tightly-coupled Fusion of Global Positional Measurements in Optimization-based Visual-Inertial Odometry

description: Motivated by the goal of achieving robust, drift-free pose estimation in long-term autonomous navigation, in this work we propose a methodology to fuse global positional information with visual and inertial measurements in a tightly-coupled nonlinear-optimization-based estimator. Differently from previous works, which are loosely-coupled, the use of a tightly-coupled approach allows exploiting the correlations amongst all the measurements. A sliding window of the most recent system states is estimated by minimizing a cost function that includes visual re-projection errors, relative inertial errors, and global positional residuals. We use IMU preintegration to formulate the inertial residuals and leverage the outcome of such algorithm to efficiently compute the global position residuals. The experimental results show that the proposed method achieves accurate and globally consistent estimates, with negligible increase of the optimization computational cost. Our method consistently outperforms the loosely-coupled fusion approach. The mean position error is reduced up to 50% with respect to the loosely-coupled approach in outdoor Unmanned Aerial Vehicle (UAV) flights, where the global position information is given by noisy GPS measurements. To the best of our knowledge, this is the first work where global positional measurements are tightly fused in an optimization-based visual-inertial odometry algorithm, leveraging the IMU preintegration method to define the global positional factors.

description: Form Factor Perturbation Theory is applied to study the spectrum of the O(3) non--linear sigma model with the topological term in the vicinity of $θ= π$. Its effective action near this value is given by the non--integrable double Sine--Gordon model. Using previous results by Affleck and the explicit expressions of the Form Factors of the exponential operators $e^{\pm i\sqrt{8π} ϕ(x)}$, we show that the spectrum consists of a stable triplet of massive particles for all values of $θ$ and a singlet state of higher mass. The singlet is a stable particle only in an interval of values of $θ$ close to $π$ whereas it becomes a resonance below a critical value $θ_c$.

Mechanistic studies of a “Declick” reaction

description: A kinetic analysis of a “declick” reaction is described. Compound 1, previously reported to couple an amine and a thiol (i.e. “click”) under mild aqueous conditions to create 2, undergoes release of the unaltered coupling partners upon triggering with dithiothreitol (DTT). In the study reported herein various aniline derivatives possessing para-electron donating and withdrawing groups were used as the amines. UV/vis spectroscopy of the declick reaction shows time-dependent spectra lacking isosbestic points, implying a multi-step mechanism. Global data ﬁtting using numerical integration of rate equations and singular value decomposition aﬀorded the spectra and time-dependence of each species, as well as rate constants for each step. The kinetic analysis reveals a multi-step process with an intermediate where both thiols of DTT have added prior to expulsion of the aniline leaving group, followed by rearrangement to the ﬁnal product. Hammett plots show a negative rho value on two of the steps, indicating positive charge building (i.e. reduction of a negative charge) in the step leading to the intermediate and its rate- determining breakdown. Overall, the kinetic study reported herein gives a complete mechanistic picture of the declick reaction.

description: We study the anomalous dimensions of single trace operators composed of field strengths $F_{μν}$ in large-N QCD. The matrix of anomalous dimensions is the Hamiltonian of a compact spin chain with two spin one representations at each vertex corresponding to the selfdual and anti-selfdual components of $F_{μν}$. Due to the special form of the interaction it is possible to study separately renormalization of purely selfdual components. In this sector the Hamiltonian is integrable and can be exactly solved by Bethe ansatz. Its continuum limit is described by the level two SU(2) WZW model.

Current-current correlations in hybrid superconducting and normal metal multiterminal structures

description: We consider a hybrid system consisting of two normal metal leads weakly connected to a superconductor. Current-current correlations of the normal leads are studied in the tunneling limit at subgap voltages and temperatures. We find that only two processes contribute to the cross-correlation: the crossed Andreev reflection (emission of electrons in different leads) and the elastic cotunneling. Both processes are possible due to the finite size of the Cooper pair. Noise measurements can thus be used to probe directly the superconducting wave function without the drawbacks appearing in average current measurements where the current is dominated by direct Andreev reflection processes. By tuning the voltages it is possible to change the sign of the cross correlation. Quantitative predictions are presented both in the diffusive and ballistic regimes.

Subjects: subject: Natural Resources and Environment
subject: Science

description: Microgrid systems powered with distributed generation (DG) technologies offer an alternative to the conventional system of centralized power and on-site thermal heating and cooling. A microgrid is defined here as a system of multiple power sources of potentially different sizes and technologies for serving aggregated electrical and thermal loads, where the power and thermal energy can be produced at or near the locations of the users. The potential benefits of microgrids are greater efficiency, reduced emissions, and lower cost (both social and financial). The analysis presented here uses the framework of life-cycle analysis (LCA) to determine the magnitude of the total fuel cycle use and emissions impact of a proposed microgrid system in Detroit, compared with the conventional system of grid-based electricity and on-site thermal heating and cooling. This analysis is a result of a partnership between NextEnergy and the University of Michigan’s Center for Sustainable Systems (CSS). NextEnergy provided a grant to CSS to build an analytical tool for evaluating the life-cycle performance of its microgrid system.

description: We report IRAM Plateau de Bure, millimeter interferometry of three z=~2.4 to 3.4, SCUBA deep field galaxies. Our CO line observations confirm the rest-frame UV/optical redshifts, thus more than doubling the number of confirmed, published redshifts of the faint submillimeter population and proving their high-z nature. In all three sources our measurements of the intrinsic gas and dynamical mass are large (1e10 to 1e11 Msun). In at least two cases the data show that the submillimeter sources are part of an interacting system. Together with recent information gathered in the X-ray, optical and radio bands our observations support the interpretation that the submm-population consists of gas rich (gas to dynamical mass ratio ~0.5) and massive, composite starburst/AGN systems, which are undergoing a major burst of star formation and are evolving into m*-galaxies.

description: We study the behaviour of a universal combination of susceptibility and correlation length in the Ising model in two and three dimensions, in presence of both magnetic and thermal perturbations, in the neighbourhood of the critical point. In three dimensions we address the problem using a parametric representation of the equation of state. In two dimensions we make use of the exact integrability of the model along the thermal and the magnetic axes. Our results can be used as a sort of "reference frame" to chart the critical region of the model. While our results can be applied in principle to any possible realization of the Ising universality class, we address in particular, as specific examples, three instances of Ising behaviour in finite temperature QCD related in various ways to the deconfinement transition. In particular, in the last of these examples, we study the critical ending point in the finite density, finite temperature phase diagram of QCD. In this finite density framework, due to well know sign problem, Montecarlo simulations are not possible and thus a direct comparison of experimental results with QFT/Statmech predictions like the one we discuss in this paper may be important. Moreover in this example it is particularly difficult to disentangle "magnetic-like" from "thermal-like" observables and thus universal quantities which do not need a precise identification of the magnetic and thermal axes, like the one we address in this paper, can be particularly useful.

description: We have derived explicit non-perturbative expression for decoherence of quantum oscillations in a qubit by low-frequency noise. Decoherence strength is controlled by the noise spectral density at zero frequency while the noise correlation time $τ$ determines the time $t$ of crossover from the $1/\sqrt{t}$ to the exponential suppression of coherence. We also performed Monte Carlo simulations of qubit dynamics with noise which agree with the analytical results and show that most of the conclusions are valid for both Gaussian and non-Gaussian noise.
