description: The proposed design includes the construction of a stormwater detention facility under the field along with a two storey underground parkade under the stadium building. Collected stormwater is stored under the field and diverted to a water treatment system. The treated water will be distributed to the stadium and the botanical garden and reused for irrigation and flushing toilets. The stored water can also infiltrate into the native soils and act as a groundwater recharge source. In case of an extreme event corresponding to a 10-year and a 100-year return period, water can be diverted to the lower level of the parkade which serves as a secondary water tank and discharged through the UBC's current pipe network. This design is effective and efficient to properly deal with the UBC's current concern related to stormwater management and prevention of floods and potential slope stability around Point Grey. The demands and capacities of the parkade were analyzed using software such as S-Frame™, S-Steel™ and S-Concrete™. The loads on the structure are composed of the dead load, vehicles load, exit load, soil pressure and snow load. The steel sections and rebar of this structure were chosen based on the CSA S16-14 and determined to be 350W and 400W respectively. The preliminary schedule for the project indicates a start on May 1st, 2019 and completion in October 2019; a total of 6 months. Additionally, the report reviews a detailed cost estimate including first costs, annual operating cost, and maintenance costs. The total expected cost is estimated at CAD $15.7 million for the parkade, detention tank and accompanying facilities construction. The parkade and water storage facility is mindful of the local environment and stakeholder interests.

description: The solution of eigenproblems is often a key computational bottleneck that limits the tractable system size of numerical algorithms, among them electronic structure theory in chemistry and in condensed matter physics. Large eigenproblems can easily exceed the capacity of a single compute node, thus must be solved on distributed-memory parallel computers. We here present GPU-oriented optimizations of the ELPA two-stage tridiagonalization eigensolver (ELPA2). On top of cuBLAS-based GPU offloading, we add a CUDA kernel to speed up the back-transformation of eigenvectors, which can be the computationally most expensive part of the two-stage tridiagonalization algorithm. We benchmark the performance of this GPU-accelerated eigensolver on two hybrid CPU-GPU architectures, namely a compute cluster based on Intel Xeon Gold CPUs and NVIDIA Volta GPUs, and the Summit supercomputer based on IBM POWER9 CPUs and NVIDIA Volta GPUs. Consistent with previous benchmarks on CPU-only architectures, the GPU-accelerated two-stage solver exhibits a parallel performance superior to the one-stage counterpart. Finally, we demonstrate the performance of the GPU-accelerated eigensolver developed in this work for routine semi-local KS-DFT calculations comprising thousands of atoms.

description: In the garnet structure compound Yb3Ga5O12, the Yb3+ ions (ground state effective spin S' = 1/2) are situated on two interpenetrating corner sharing triangular sublattices such that frustrated magnetic interactions are possible. Previous specific heat measurements evidenced the development of short range magnetic correlations below 0.5K and a lambda-transition at 54mK (Filippi et al. J. Phys. C: Solid State Physics 13 (1980) 1277). From 170-Yb M"ossbauer spectroscopy measurements down to 36mK, we find there is no static magnetic order at temperatures below that of the lambda-transition. Below 0.3K, the fluctuation frequency of the short range correlated Yb3+ moments progressively slows down and as the temperature tends to 0, the frequency tends to a quasi-saturated value of 3 x 10^9 s^-1. We also examined the Yb3+ paramagnetic relaxation rates up to 300K using 172-Yb perturbed angular correlation measurements: they evidence phonon driven processes.

description: Developers often need to use appropriate APIs to program efficiently, but it is usually a difficult task to identify the exact one they need from a vast of candidates. To ease the burden, a multitude of API recommendation approaches have been proposed. However, most of the currently available API recommenders do not support the effective integration of users' feedback into the recommendation loop. In this paper, we propose a framework, BRAID (Boosting RecommendAtion with Implicit FeeDback), which leverages learning-to-rank and active learning techniques to boost recommendation performance. By exploiting users' feedback information, we train a learning-to-rank model to re-rank the recommendation results. In addition, we speed up the feedback learning process with active learning. Existing query-based API recommendation approaches can be plugged into BRAID. We select three state-of-the-art API recommendation approaches as baselines to demonstrate the performance enhancement of BRAID measured by Hit@k (Top-k), MAP, and MRR. Empirical experiments show that, with acceptable overheads, the recommendation performance improves steadily and substantially with the increasing percentage of feedback data, comparing with the baselines.

description: The scattering of electrons on impurities with internal degrees of freedom is bound to produce the signatures of the scatterer's own dynamics and results in nontrivial electronic transport properties. Previous studies of polaronic impurities in low-dimensional structures, like molecular junctions and one-dimensional nanowire models, have shown that perturbative treatments cannot account for a complex energy dependence of the scattering cross section in such systems. Here we derive the exact solution of polaronic impurities shaping the electronic transport in bulk (3D) systems. In the model with a short-ranged electron-phonon interaction, we solve for and sum over all elastic and inelastic partial cross sections, abundant in resonant features. The temperature dependence of the charge mobility shows the power-law dependence, $μ(T)\propto T^{-ν}$, with $ν$ being highly sensitive to impurity parameters. The latter may explain nonuniversal power-law exponents observed experimentally, e.g. in high-quality organic molecular semiconductors.

description: This paper compares the technical and economic feasibilities of small scale production of fuel grade grain alcohol with those of sunflower oil. Three scales of ethanol and sunflower oil production are modeled, and sensitivity analysis is conducted for different operating conditions and costs of feedstocks and by-products. The general conclusion is that, ignoring government subsidies to alcohol production, sunflower oil is competitive with alcohol at these scales of operation.

description: With the recent release of large (i.e., > hundred million objects), well-calibrated photometric surveys, such as DPOSS, 2MASS, and SDSS, spectroscopic identification of important targets is no longer a simple issue. In order to enhance the returns from a spectroscopic survey, candidate sources are often preferentially selected to be of interest, such as brown dwarfs or high redshift quasars. This approach, while useful for targeted projects, risks missing new or unusual species. We have, as a result, taken the alternative path of spectroscopically identifying interesting sources with the sole criterion being that they are in low density areas of the g - r and r - i color-space defined by the DPOSS survey. In this paper, we present three peculiar broad absorption line quasars that were discovered during this spectroscopic survey, demonstrating the efficacy of this approach. PSS J0052+2405 is an Iron LoBAL quasar at a redshift z = 2.4512 with very broad absorption from many species. PSS J0141+3334 is a reddened LoBAL quasar at z = 3.005 with no obvious emission lines. PSS J1537+1227 is a Iron LoBAL at a redshift of z = 1.212 with strong narrow Mgii and Feii emission. Follow-up high resolution spectroscopy of these three quasars promises to improve our understanding of BAL quasars. The sensitivity of particular parameter spaces, in this case a two-color space, to the redshift of these three sources is dramatic, raising questions about traditional techniques of defining quasar populations for statistical analysis.

The metric dimension of critical Galton-Watson trees and linear preferential attachment trees

description: The metric dimension of a graph $G$ is the minimal size of a subset $R$ of vertices of $G$ that, upon reporting their graph distance from a distingished (source) vertex $v^\star$, enable unique identification of the source vertex $v^\star$ among all possible vertices of $G$. In this paper we show a Law of Large Numbers (LLN) for the metric dimension of some classes of trees: critical Galton-Watson trees conditioned to have size $n$, and growing general linear preferential attachment trees. The former class includes uniform random trees, the latter class includes Yule-trees (also called random recursive trees), $m$-ary increasing trees, binary search trees, and positive linear preferential attachment trees. In all these cases, we are able to identify the limiting constant in the LLN explicitly. Our result relies on the insight that the metric dimension can be related to subtree properties, and hence we can make use of the powerful fringe-tree literature developed by Aldous and Janson et al.
Determination of Young's modulus of samples of arbitrary thickness from force distance curves: numerical investigations and simple approximate formulae
Creators: name: Hermanowicz, Paweł

Year: 2020
Subjects: subject: Classical Physics (physics.class-ph)

description: We present simple expressions for load required to indent a layer of arbitrary thickness with a conical, paraboloidal or cylindrical punch. A rigid substrate underneath the sample leads to an increase of load required for indentation. This effect has to be corrected for to prevent overestimation of Young's modulus from indentation measurements, such as force - distance curves recorded with the Atomic Force Microscope (AFM). The problems of the frictionless contact of an axisymmetric punch and an isotropic, linear-elastic layer are reducible to Fredholm integral equations of the second kind. We solved them numerically and used the Remez algorithm to obtain piecewise polynomial approximations of the load - indentation relation for samples that are either in frictionless contact with the rigid substrate or bonded to it. Their relative error due to approximation is negligible and uniformly spread. Combining the numerical approximations with asymptotic solutions for very thin layers, we obtained equations appropriate for samples of arbitrary thickness. They were implemented in a new version of AtomicJ, our free, open source application for analysis of AFM recordings.

description: In the next few years, major expansion of the production of ethanol from grain could take place. With current technology and government subsidies, ethanol is economically competitive for use as an automotive fuel. The limiting factor to growth likely will be plant capacity. Projections indicate that annual production capacity could reach two billion gallons in several years (Tyner, and Meekhof, Gill and Tyner). Production of two billion gallons would use 770 million bushels of corn--equivalent to the corn production of Nebraska in recent years.

description: Wide-field magnetometry can be realized by imaging the optically-detected magnetic resonance of diamond nitrogen vacancy (NV) center ensembles. However, NV ensemble inhomogeneities significantly limit the magnetic-field sensitivity of these measurements. We demonstrate a double-double quantum (DDQ) driving technique to facilitate wide-field magnetic imaging of dynamic magnetic fields at a micron scale. DDQ imaging employs four-tone radio frequency pulses to suppress inhomogeneity-induced variations of the NV resonant response. As a proof-of-principle, we use the DDQ technique to image the dc magnetic field produced by individual magnetic-nanoparticles tethered by single DNA molecules to a diamond sensor surface. This demonstrates the efficacy of the diamond NV ensemble system in high-frame-rate magnetic microscopy, as well as single-molecule biophysics applications.

Subjects: Land Economics/Use

description: The NE-125 regional project was undertaken with a general hypothesis that the changing patterns of ownership (or owner characteristics) would affect attitudes of the owners. These changes are apt to result in conflicts and also affect land use patterns. It was believed, for example, that newer residents would be different in their views than those residents who had lived in an area for longer periods of time. Perhaps they would be more in favor of land use controls. Other socio-economic factors also were believed to be important in shaping people's attitudes.

description: The ability of autonomous vehicles to maintain an accurate trajectory within their road lane is crucial for safe operation. This requires detecting the road lines and estimating the car relative pose within its lane. Lateral lines are usually retrieved from camera images. Still, most of the works on line detection are limited to image mask retrieval and do not provide a usable representation in world coordinates. What we propose in this paper is a complete perception pipeline based on monocular vision and able to retrieve all the information required by a vehicle lateral control system: road lines equation, centerline, vehicle heading and lateral displacement. We evaluate our system by acquiring data with accurate geometric ground truth. To act as a benchmark for further research, we make this new dataset publicly available at http://airlab.deib.polimi.it/datasets/.

description: Our team has been retained by UBC to develop a multi-use stormwater retention system reflecting the need to address the event of a 100 year return period storm. This call to action is as result of of a need to address and prevent cliff erosion off the Southwest Marine Drive and Point Grey area. The system shall be situated adjacent to the UBC Center for Comparative Medicine (CCM) and shall encompass key design criteria as laid out by Mr. Doyle while adhering to UBC SEEDS Department’s criteria to sustainability at UBC. As result, our team is proposing a multi-use Velodrome design to combat the 100 year return period storm whilst also providing an excellent cornerstone for growth within the UBC community. The Velodrome will also be encompassing a park within it as to further push UBC SEEDS Department’s criteria to sustainability and a greener image. The system will limit the outflow to approximately 1.2 m3/s. Additionally, the volumetric capacity will contain 3,400 cubic meters of water and fulfills the BC Water Quality Guidelines for the discharge of water. Given the provided geological data, soil conditions and borehole data, our team has developed a design structure and ensuing calculations to support the development of the UBC Velodrome. Additionally, Issued for Construction (IFC) drawings are enclosed for the construction of this project. Utilizing UBC, Metro Vancouver, Canadian, and other applicable guidelines, the construction processes are identified and a proposed schedule of the entire project is enclosed. Using RSMeans, other notable municipal and federal projects information, and finalized details in our service life and maintenance plan including the time value of money and interest rates, our Class C cost estimate has been updated to a Class B cost estimate. Additionally, our team will include considerations for the service life and maintenance of the UBC Velodrome as well as recommendations for its design.

description: In this paper we study the latent demand structure for food diversity in India using data from the 2012 Consumer Expenditure Survey. We assume that consumers who have not yet attained calorie sufficiency favor calories over food diversity and once passing a threshold of subsistence substitute away from staples towards a more varied diet.This implies a latent demand pattern as calorie sufficiency depends on unobservable individual characteristics. Latent classes and consumption patterns are identified by means of finite mixture models. Therefore we examine the link between food diversity indices and socioeconomic indicators, explain component memberships in order to characterize latent classes and evaluate nutritional implications. Two clearly distinct demand patterns for diversity could be identified, consistent with the initial assumptions. The identified classes differ substantially in income, household composition and nutritional adequacy.

description: Using the Becker-DeGroot-Marschak (BDM) mechanism, we estimate the willingness-to-pay (WTP) for and impact of clean water technology through a field experiment in Ghana. Although WTP is low relative to the cost, demand is relatively inelastic at low prices. In the short-run, treatment effects are positive—the incidence of children’s diarrhea falls by one third—and consistent throughout the WTP distribution. After a year, usage has fallen, particularly for those with relatively low valuations. Strikingly, the long-run average treatment effect is negative for those with valuations below the median. Combining estimated treatment effects with individual willingness-to pay measures implies households’ valuations of health benefits are much smaller than those typically used by policymakers. Finally, we explore differences between BDM and take-it-or-leave-it valuations and make recommendations for effectively implementing BDM in the field.
Can Supersymmetry Naturally Explain the Positron Excess?

description: It has often been suggested that the cosmic positron excess observed by the HEAT experiment could be the consequence of supersymmetric dark matter annihilating in the galactic halo. Although it is well known that evenly distributed dark matter cannot account for the observed excess, if substantial amounts of local dark matter substructure are present, the positron flux would be enhanced, perhaps to the observed magnitude. In this paper, we attempt to identify the nature of the substructure required to match the HEAT data, including the location, size and density of any local dark matter clump(s). Additionally, we attempt to assess the probability of such substructure being present. We find that if the current density of neutralino dark matter is the result of thermal production, very unlikely ($\sim 10^{-4}$ or less) conditions must be present in local substructure to account for the observed excess.

Magnetic properties of Yb2Mo2O7 and Gd2Mo2O7 from rare earth Mossbauer measurements

description: Using 170-Yb and 155-Gd Mossbauer measurements down to 0.03K, we have examined the semiconducting pyrochlore Yb2Mo2O7 where the Mo intra-sublattice interaction is anti-ferromagnetic and the metallic pyrochlore Gd2Mo2O7 where this interaction is ferromagnetic. Additional information was obtained from susceptibility, magnetisation and 172-Yb perturbed angular correlation measurements. The microscopic measurements evidence lattice disorder which is important in Yb2Mo2O7 and modest in Gd2Mo2O7. Magnetic irreversibilities occur at 17K in Yb2Mo2O7 and at 75K in Gd2Mo2O7 and below these temperatures the rare earths carry magnetic moments which are induced through couplings with the Mo sublattice. In Gd2Mo2O7, we observe the steady state Gd hyperfine populations at 0.027K are out of thermal equilibrium, indicating that Gd and Mo spin fluctuations persist at very low temperatures. Frustration is thus operative in this essentially isotropic pyrochlore where the dominant Mo intra-sublattice interaction is ferromagnetic.
