description: $\Kbar N$ interactions are investigated {\it via} an effective non-linear chiral meson-baryon Lagrangian. The adjustable parameters are determined by a fitting procedure on the $K^-p$ threshold branching ratios and total cross-section data for $p^{lab}_K\le$ 250 MeV/c. We produce predictions for the $Σπ$ mass spectrum, and scattering lenghts $a_{K^-p}$, $a_n(K^-n \to K^-n)$, $a_n0(\Kbar0 n \to \Kbar0 n)$, and $a_{ex}(K^-p \to \Kbar0 n)$. The $\Kbar N$ amplitudes thus obtained, as well as those for other two-body channels ($πN$, $NN$, and $YN$) are used as input to predict the scattering length $A_{K^-d}$, for which we have devised a relativistic version of the three-body Faddeev equations. Results for all two- and three-body coupled channels are reported both in isospin and particle bases. All available $\Kbar N$ data are well reproduced and our best results for the $K^-p$ and $K^-d$ scattering lenghts are $a_{K^-p} = (-0.90 + i 0.87) fm$ and $A_{K^-d} = (-1.80 + i 1.55) fm$.

description: The Dirac mass of a two-dimensional QAH insulator is directly related to the parity anomaly of planar quantum electrodynamics, as shown initially in Phys. Rev. Lett. 52, 18 (1984). In this work, we connect the additional momentum-dependent Newtonian mass term of a QAH insulator to the parity anomaly. By calculating the effective action, we reveal that the Newtonian mass term acts like a parity-breaking element of a high-energy regularization scheme. As such, it is directly related to the parity anomaly. In addition, the calculation of the effective action allows us to determine the finite frequency correction to the DC Hall conductivity of a QAH insulator. We derive that the leading order AC correction contains a term proportional to the torsional Hall viscosity. This paves the way to measure this non-dissipative transport coefficient via electrical or magneto-optical experiments. Moreover, we prove that the Newtonian mass significantly changes the resonance structure of the AC Hall conductivity in comparison to pure Dirac systems like graphene.

description: Many simulations of stochastic processes require colored noises: I describe here an exact numerical method to simulate power-law noises: the method can be extended to more general colored noises, and is exact for all time steps, even when they are unevenly spaced (as may often happen for astronomical data, see e.g. N. R. Lomb, Astrophys. Space Sci. {\bf 39}, 447 (1976)). The algorithm has a well-behaved computational complexity, it produces a nearly perfect Gaussian noise, and its computational efficiency depends on the required degree of noise Gaussianity.

description: The article deals with the extension of the relativistic double-ionization equation-of-motion coupled-cluster (DI-EOMCC) method [H. Pathak et al. Phys. Rev. A 90, 010501(R) (2014)] for the molecular systems. The Dirac-Coulomb (DC) Hamiltonian with four-component spinors is considered to take care of the relativistic effects. The implemented method is employed to compute a few low-lying doubly ionized states of noble gas atoms (Ar, Kr, Xe, and Rn) and Cl 2 , Br 2 , HBr, and HI. Additionally, we presented results with two intermediate schemes in the four-component relativistic DI-EOMCC framework to understand the role of electron correlation. The computed double ionization spectra for the atomic systems are compared with the values from the non-relativistic DI-EOMCC method with spin-orbit coupling (SOC) [Z. Wang et al. J. Chem. Phys. 142, 144109 (2015)] and the values from the National Institute of Science and Technology (NIST) database. Our atomic results are found to be in good agreement with the NIST values. Further, the obtained results for the molecular systems agree well with the available experimental values.

An investigation into a grocery store in the new Student Union Building

Year: 2014

description: When the new Student Union Building at the University of British Columbia opens in 2014, the Alma Mater Society and independent tenants will be operating a variety of food outlets, shops and services. A student grocery store has been proposed as an alternative to the ready-made, pre-packaged food currently available in the old Student Union Building. The Alma Mater Society is interested in an environmentally friendly, healthy alternative to the ready-made pre-packaged food outlets but needs more information on the viability of operating a grocery store. Ideally, the Alma Mater Society would like to lease space in the new Student Union Building to a third party tenant who has expertise as well as experience operating a grocery store. To advise the Alma Mater society, a triple bottom line analysis was conducted analyzing the economic, social and environmental aspects of various third party store options. Economically, the Alma Mater Society is willing to experiment with this project and is not concerned with having a large return on the investment but would like the potential grocery store to stay net positive. As environmental factors are very important to UBC, and how large a carbon footprint produced by the store is looked at closely, the produce is restricted to being locally grown. Plastic bags will be either charged a nominal fee or not be included in the purchase of food. Socially, students from varying disciplines were polled to obtain date that would show whether or not there is public interest in a student grocery store. The results of the poll were positive, and indicated that a student grocery store would be well used. Local produce stores were phoned to obtain data that would show if the market place was interested in the proposition. The results of phoning varying produce stores was positive, and only asked that there be more information on hand to give them so that they can make a more informed decision. The results from the triple bottom line analysis concluded that the Student Grocery Store appears to be feasible. A more in-depth analysis is recommended to peruse the concept of a grocery store.

Subjects: Financial Economics

description: The market for multi-channel video programming has undergone considerable change in the last 15 years. Direct-Broadcast Satellite service, spurred by 1999 legislation that leveled the playing field with cable television systems, has grown from 3% to 33% of the U.S. MVPD (cable, satellite, and telco video) market. Telephone operators have entered in some parts of the US and online video distributors are a growing source of television viewing. This chapter considers the merits of cable television regulation in light of these developments. It surveys the dismal empirical record on the effects of price regulation in cable and the more encouraging but incomplete evidence on the benefits of satellite and telco competition. It concludes with a consideration of four open issues in cable markets: horizontal concentration and vertical integration in the programming market, bundling by both cable systems and programmers, online video distribution, and temporary programming blackouts from failed carriage negotiations for both broadcast and cable programming. While the distribution market is clearly now more competitive, concerns in each of these areas remain.

description: The modulational instability of spatially uniform states in the nonlinear Schrödinger equation is examined in the presence of higher-order dissipation. The study is motivated by results on the effects of three-body recombination in Bose-Einstein condensates, as well as by the important recent work of Segur et al. on the effects of linear damping in NLS settings. We show how the presence of even the weakest possible dissipation suppresses the instability on a longer time scale. However, on a shorter scale, the instability growth may take place, and a corresponding generalization of the MI criterion is developed. The analytical results are corroborated by numerical simulations. The method is valid for any power-law dissipation form, including the constant dissipation as a special case.

description: Motivated by the astonishing capabilities of natural intelligent agents and inspired by theories from psychology, this paper explores the idea that perception gets coupled to 3D properties of the world via interaction with the environment. Existing works for depth estimation require either massive amounts of annotated training data or some form of hard-coded geometrical constraint. This paper explores a new approach to learning depth perception requiring neither of those. Specifically, we train a specialized global-local network architecture with what would be available to a robot interacting with the environment: from extremely sparse depth measurements down to even a single pixel per image. From a pair of consecutive images, our proposed network outputs a latent representation of the observer's motion between the images and a dense depth map. Experiments on several datasets show that, when ground truth is available even for just one of the image pixels, the proposed network can learn monocular dense depth estimation up to 22.5% more accurately than state-of-the-art approaches. We believe that this work, despite its scientific interest, lays the foundations to learn depth from extremely sparse supervision, which can be valuable to all robotic systems acting under severe bandwidth or sensing constraints.

description: Special features of surface gravity waves in deep fluid flow with constant vertical shear of velocity is studied. It is found that the mean flow velocity shear leads to non-trivial modification of surface gravity wave modes dispersive characteristics. Moreover, the shear induces generation of surface gravity waves by internal vortex mode perturbations. The performed analytical and numerical study provides, that surface gravity waves are effectively generated by the internal perturbations at high shear rates. The generation is different for the waves propagating in the different directions. Generation of surface gravity waves propagating along the main flow considerably exceeds the generation of surface gravity waves in the opposite direction for relatively small shear rates, whereas the later wave is generated more effectively for the high shear rates. From the mathematical point of view the wave generation is caused by non self-adjointness of the linear operators that describe the shear flow.

description: To date, investigations of carrier-envelope-phase (CEP) dependent effects have been limited to optical pulses with few cycles and high intensity, and have not been reported for other types of pulses. Optomechanical systems are shown to have the potential to go beyond these limits. We present an approach using optomechanics to extend the concept of the traditional CEP in the few-cycle regime to mechanical pulses and develop a two-step model to give a physical insight. By adding an auxiliary continuous optical field, we show that a CEP-dependent effect appears even in the multi-cycle regime of mechanical pulses. We obtain the approximated analytical solutions providing full understanding for these optomechanically induced CEP-dependent effects. In addition, our findings show that one can draw on the optomechanical interaction to revive the CEP-dependent effects on optical pulses with an arbitrary number of cycles and without specific intensity requirements. The effects of CEP, broadly extended to encompass few- and multi-cycle optical and mechanical pulses, may stimulate a variety of applications in the preparation of a CEP-stabilized pulse, the generation of ultrasonic pulses with a desired shape, the linear manipulation of optical combs, and more.

description: The idea that GRBs originate from uniform jets has been used to explain numerous observations of breaks in the GRB afterglow lightcurves. We explore the possibility that GRBs instead originate from a structured jet that may be quasi-universal, where the variation in the observed properties of GRBs is due to the variation in the observer viewing angle. We test how various models reproduce the jet data of Bloom, Frail, & Kulkarni (2003), which show a negative correlation between the isotropic energy output and the inferred jet opening angle (in a uniform jet configuration). We find, consistent with previous studies, that a power-law structure for the jet energy as a function of angle gives a good description. However, a Gaussian jet structure can also reproduce the data well, particularly if the parameters of the Gaussian are allowed some scatter. We place limits on the scatter of the parameters in both the Gaussian and power-law models needed to reproduce the data, and discuss how future observations will better distinguish between these models for the GRB jet structure. In particular, the Gaussian model predicts a turnover at small opening angles and in some cases a sharp cutoff at large angles, the former of which may already have been observed. We also discuss the predictions each model makes for the observed luminosity function of GRBs and compare these predictions with the existing data.

description: The dark exciton state in semiconductor quantum dots (QDs) constitutes a long-lived solid-state qubit which has the potential to play an important role in implementations of solid-state-based quantum information architectures. In this work, we exploit deterministically fabricated QD microlenses which promise enhanced photon extraction, to optically prepare and read out the dark exciton spin and observe its coherent precession. The optical access to the dark exciton is provided via spin-blockaded metastable biexciton states acting as heralding states, which are identified by deploying polarization-sensitive spectroscopy as well as time-resolved photon cross-correlation experiments. Our experiments reveal a spin-precession period of the dark exciton of (0.82 ± 0.01) ns corresponding to a fine-structure splitting of (5.0 ± 0.7) μeV between its eigenstates ||↑⇑±↓⇓⟩. By exploiting microlenses deterministically fabricated above pre-selected QDs, our work demonstrates the possibility to scale up implementations of quantum information processing schemes using the QD-confined dark exciton spin qubit, such as the generation of photonic cluster states or the realization of a solid-state-based quantum memory.

description: The interplay between religion and the economy has occupied social scientists for long. We construct a unique panel of income and Protestant church attendance for six waves of up to 175 Prussian counties spanning 1886-1911. The data reveal a marked decline in church attendance coinciding with increasing income. The cross-section also shows a negative association between income and church attendance. But the association disappears in panel analyses, including firstdifferenced models of the 1886-1911 change, panel models with county and time fixed effects, and panel Granger-causality tests. The results cast doubt on causal interpretations of the religioneconomy nexus in Prussian secularization.

description: High-sensitivity imaging of ultracold atoms is often challenging when interference patterns are imprinted on the imaging light. Such image noises result in low signal-to-noise ratio and limit the capability to extract subtle physical quantities. Here we demonstrate an advanced fringe removal algorithm for absorption imaging of ultracold atoms, which efficiently suppresses unwanted fringe patterns using a small number of sample images without taking additional reference images. The protocol is based on an image decomposition and projection method with an extended image basis. We apply this scheme to raw absorption images of degenerate Fermi gases for the measurement of atomic density fluctuations and temperatures. The quantitative analysis shows that image noises can be efficiently removed with only tens of reference images, which manifests the efficiency of our protocol. Our algorithm would be of particular interest for the quantum emulation experiments in which several physical parameters need to be scanned within a limited time duration.

description: We generalize Dykhne's calculation of the effective resistance of a 2D two-component medium to the case of frictional drag between the two parallel two-component layers. The resulting exact expression for the effective transresistance, $ρ^D_{eff}$, is analyzed in the limits when the resistances and transresistances of the constituting components are strongly different - situation generic for the vicinity of the {\em classical} (percolative) metal-insulator transition (MIT). On the basis of this analysis we conclude that the evolution of $ρ^D_{eff}$ across the MIT is determined by the type of correlation between the components, constituting the 2D layers. Depending on this correlation, in the case of two electron layers, $ρ^D_{eff}$ changes either monotonically or exhibits a sharp maximum. For electron-hole layers $ρ^D_{eff}$ is negative and $|ρ^D_{eff}|$ exhibits a sharp minimum at the MIT.

Entrepreneurs strongly a§ect Örm growth patterns of both very young Örms and for Örms that have begun to mature. We do not Önd signiÖcant di§erences between small and larger Örms, family and non-family Örms, nor between Örms located in urban and rural areas, but we do Önd stronger e§ects for founders with high human capital.

description: Founded in 1817, the University of Michigan (U-M) is an internationally renowned research and undergraduate, graduate, and professional educational institution with a broad curriculum in the liberal arts. Spanning three campuses in Ann Arbor, Flint and Dearborn, the U-M's mission is: -"to serve the people of Michigan and the world through preeminence in creating, communicating, preserving and applying knowledge, art, and academic values, and in developing leaders and citizens who will challenge the present and enrich the future." The primary goal of the U-M is to fulfill this mission. Increasingly, however, it has recognized as a priority the need to do so in a way that is sustainable. Developed with the invaluable assistance of over 30 departments within the U-M and the peer review of a diverse group of external stakeholders, this report introduces a framework and indicators for assessing the "triple bottom line" sustainability of the U-M, and presents a first assessment of the U-M's historical and current performance.

description: The weighted voting system used by the International Monetary Fund creates problems of democratic legitimacy since each member's influence or voting power is not in general equal to its voting weight. Using voting power analysis to analyse both the Board of Governors and the Executive Board, we show that it tends to enhance the power of the United States at the expense of all other members. We investigate the constituency system as a form of representative democracy, idealizing it as a compound voting body, and find that it gives disproportionately large power to some smaller European countries, particularly Belgium and Netherlands. We also find that many countries are effectively disenfranchised. Separate analyses are done for 2006 and 2012, before and after recent reforms, which have been billed as being radical, enhancing the voice of the poor and emerging markets, but the effects are disappointingly small.

description: Cosmological LCDM simulations of 12 M_vir~10^14 Msun galaxy groups have been performed, invoking star formation, chemical evolution with non-instantaneous recycling, metallicity dependent radiative cooling, strong star-burst driven galactic super-winds and effects of a meta-galactic UV field. At z=0, intra-group light (IGL) fractions are found to be 12-45%. Low values refer to groups with only a small difference between the R-band magnitudes of the first and second ranked group galaxy, large are typical of "fossil" groups (FGs). The IG stars in the 4 FGs are 0.3-0.5 Gyr older than in the 8 nonFGs. For the IGL, B-R=~1.4, in good agreement with observations. For FGs/nonFGs the iron abundance of the IG stars is slightly sub-solar in the central parts (r~100 kpc) decreasing to about 40% solar at about 0.5 r_vir The IG stars are alpha-element enhanced with [O/Fe] increasing with r, and an overall [O/Fe]~0.45, indicating predominant SNII enrichment. The velocity distributions of the IG stars and group galaxies are, at r>~30 kpc, significantly more radially anisotropic for FGs than for nonFGs. So a characteristic of FG formation, apart from formation time (D'Onghia et al.), may be the "initial" velocity distribution of the group galaxies. For FGs one can dynamically infer the (dark matter dominated) mass distribution of the groups all the way to r_vir, from the kinematics of the IG stars or group galaxies. For the nonFGs this method overestimates the group mass at r>~200 kpc, by up to a factor of two at r_vir. This is interpreted as FGs being, in general, more relaxed than nonFGs. Finally, FGs of the above M_vir should host ~500 planetary nebulae at projected distances between 100 and 1000 kpc from the first ranked galaxy. All results appear consistent with the FG formation scenario of D'Onghia et al.

description: This paper studies a dynamic model of a market such as a labour market in which firms post wages and search for workers but trade may occur at a negotiated wage procedure in markets characterized by match-specific heterogeneity. We study a model of a market in which, in each time period, agents on one side (e.g., sellers) choose whether or not to post a price before they encounter agents of the opposite type. After a pair of agents have encountered each other, their match-specific values from trading with each other are realized. If a price was not posted, then the terms of trade (and whether or not it occurs) are determined by bargaining. Otherwise, depending upon the agents’ match-specific trading values, trade occurs (if it does) either on the posted price or at a renegotiated price. We analyze the symmetric Markov subgame perfect equilibria of this market game, and address a variety of issues such as the impact of market frictions on the equilibrium proportion of trades that occur at a posted price rather than at a negotiated price.

description: The Technologies for African Agricultural Transformation (TAAT) program is a comprehensive initiative designed to boost agricultural productivity in Africa. It recognizes the crucial role of the private sector in driving innovation and investment in this area. TAAT facilitates the adoption and commercialization of high-performance agricultural technologies by the private sector, reaching millions of farmers. The program also connects the private sector with large agricultural development investments. One of TAAT's key components is the African Cereal and Legume Breeding Consortium (ACLBC), which aims to scale the adoption of elite seed varieties among seed companies to enhance access by users.

description: Many governments wish to assess the quality of their universities. A prominent example is the UK’s new Research Excellence Framework (REF) 2014. In the REF, peer-review panels will be provided with information on publications and citations. This paper suggests a way in which panels could choose the weights to attach to these two indicators. The analysis draws in an intuitive way on the concept of Bayesian updating (where citations gradually reveal information about the initially imperfectly-observed importance of the research). Our study should not be interpreted as the argument that only mechanistic measures ought to be used in a REF.

description: We present a statistical study of the filamentary structures of the cosmic web in the large hydro-dynamical simulations Illustris-TNG, Illustris, and Magneticum at redshift z=0. We focus on the radial distribution of the galaxy density around filaments detected using the Discrete Persistent Structure Extractor (DisPerSE). We show that the average profile of filaments presents an excess of galaxy density (> 5 sigma) up to radial distances of 27 Mpc from the core. The relation between galaxy density and the length of filaments is further investigated showing that short (L_f < 9 Mpc) and long (L_f > 20 Mpc) filaments are two statistically different populations. Short filaments are puffier, denser, and more connected to massive objects, whereas long filaments are thinner, less dense, and more connected to less massive structures. These two populations trace different environments and may correspond to bridges of matter between over-dense structures (short filaments), and to cosmic filaments shaping the skeleton of the cosmic web (long filaments). Through Markov Chain Monte Carlo (MCMC) explorations, we find that the density profiles of both short and long filaments can be described by the same empirical models (generalised Navarro, Frenk and White, beta-model, a single and a double power law) with different and distinct sets of parameters.

description: We implement, at next-to-next-to-leading order, the QCD corrections to Standard Model Higgs boson production in association with vector bosons at hadron colliders, $q\bar{q} \to HV$ with $V=W,Z$. They consist of the two--loop corrections to the Drell--Yan process for the production of off-shell vector bosons, $q\bar{q} \to V^*$, and in the case of $Z$ final states, of the additional contribution from heavy-quark loop mediated processes, in particular $gg \to HZ$. For the Higgs boson masses relevant at the Tevatron and the LHC, $M_H \lsim 200$--300 GeV, the two-loop corrections are small, increasing the production cross sections by less than 5% and 10%, respectively; the scale dependence is reduced to a level of less than a few per cent. This places these processes among the most theoretically clean Higgs boson production channels at hadron colliders.

description: Volumetric video is an emerging technology for immersive representation of 3D spaces that captures objects from all directions using multiple cameras and creates a dynamic 3D model of the scene. However, processing volumetric content requires high amounts of processing power and is still a very demanding task for today's mobile devices. To mitigate this, we propose a volumetric video streaming system that offloads the rendering to a powerful cloud/edge server and only sends the rendered 2D view to the client instead of the full volumetric content. We use 6DoF head movement prediction techniques, WebRTC protocol and hardware video encoding to ensure low-latency in different parts of the processing chain. We demonstrate our system using both a browser-based client and a Microsoft HoloLens client. Our application contains generic interfaces that allow for easy deployment of various augmented/mixed reality clients using the same server implementation.

description: The issue of environment and sustainability has been one of the most debated topics within the last fifty years. Governments and companies around the world have been looking into numerous sustainable solutions in which environmental footprints can be minimized without jeopardizing the living standards. A major environmental concern today deals with paper and how environmentally unsustainable it is to produce paper from wood fibre. Therefore, manufacturers and scientists have developed a more sustainable paper solution: the sugar cane and wheat waste paper. The papers are made from the remains of sugar cane and wheat straw that is traditionally plowed back into the soil. Thus, by making use of such waste materials, the use of resources is maximized. While both the sugar cane and wheat waste paper can be a sustainable paper solution, a suitable alternative must be chosen as the substitute for wood fibre paper. In order to differentiate which alternative is the best, this report looks into the impact of selecting both sugar cane and wheat waste paper on the Canadian economy. Note that this report only focuses on the economic impacts of the alternatives; therefore the environmental and social factors are ignored. This report compares the advantages and disadvantages of both sugar cane and wheat waste fibre paper on the Canadian economy in order to recommend the best alternatives for replacing wood fibre paper. Furthermore, these advantages and disadvantages is determined by analyzing the origin of raw materials and products, manufacturing costs, labour and long run effect once chosen as an alternative. Once these data is obtained, a prediction of the impact on the Canadian economy when a suitable alternative is chosen is made. This prediction is based on previous similar occurrences that have occurred within the pulp and paper industry.

description: In the United States, the predominant mode of personal transportation is the automobile with over 90% of all passenger miles traveled in 1997 (Davis and Diegel 2002). Similarly, total passenger miles traveled annually in the U.S. have been growing at nearly three times the rate of population over past two decades. With transportation contributing more than 25% of global carbon dioxide emissions (WBCSD 2001) and personal vehicles accounting for 14% of U.S. energy use (Davis and Diegel 2002), the critical role of the automobile in sustainability challenges is clear. The development of meaningful sustainable mobility solutions requires detailed understanding of the relationships between vehicle economics, vehicle performance, individual behavior, emissions, and more general societal and community factors. This study provides a framework for understanding overall vehicle economics and key economic variables in relation to individual ownership costs, operating decisions and replacement intervals. In combination with a parallel study of vehicle emissions and the implications for retirement (Kim et al. 2003), a more comprehensive view of the complex economic, environmental, and social system surrounding automobile use in the US is possible.
