description: We present a survey for low-ionization metal absorption line systems towards 17 QSOs at redshifts z_em=5.8-6.4. Nine of our objects were observed at high resolution with either Keck/HIRES or Magellan/MIKE, and the remainder at moderate resolution with Keck/ESI. The survey spans 5.3 < z_abs < 6.4 and has a pathlength interval ΔX=39.5, or Δz=8.0. In total we detect ten systems, five of which are new discoveries. The line-of-sight number density is consistent with the combined number density at z~3 of DLAs and sub-DLAs, which comprise the main population of low-ionization systems at lower redshifts. This apparent lack of evolution may occur because low ionization systems are hosted by lower-mass halos at higher redshifts, or because the mean cross section of low-ionization gas at a given halo mass increases with redshift due to the higher densities and lower ionizing background. The roughly constant number density notably contrasts with the sharp decline at z > 5.3 in the number density of highly-ionized systems traced by C IV. The low-ionization systems at z~6 span a similar range of velocity widths as lower-redshift sub-DLAs but have significantly weaker lines at a given width. This implies that the mass-metallicity relation of the host galaxies evolves towards lower metallicities at higher redshifts. These systems lack strong Si IV and C IV, which are common among lower-redshift DLAs and sub-DLAs. This is consistent, however, with a similar decrease in the metallicity of the low- and high-ionization phases, and does not necessarily indicate a lack of nearby, highly-ionized gas. The high number density of low-ionization systems at z~6 suggests that we may be detecting galaxies below the current limits of i-dropout and Ly-alpha emission galaxy surveys. These systems may therefore be the first direct probes of the `typical' galaxies responsible for hydrogen reionization.

Real-time safety and mobility optimization of traffic signals in a connected-vehicle environment
Creators: name: Essa, Mohamed
Publisher: name: University of British Columbia
Year: 2020

description: Adaptive traffic signal control (ATSC) strategies are a promising approach to improving the efficiency of signalized intersections, especially in the era of connected vehicles (CVs) where real-time information on vehicle positions and trajectories is available. Recently, numerous ATSC algorithms have been proposed to accommodate real-time traffic conditions and optimize traffic efficiency. The common objective of these algorithms is to minimize total delays or maximize vehicle throughputs. Despite their positive impacts on traffic mobility, existing ATSC algorithms do not consider optimizing traffic safety. This is most likely due to the lack of tools to evaluate the safety of signalized intersections in real time. This thesis presents several advances toward the real-time safety and mobility optimization of traffic signals in a connected-vehicle environment. First, new models for the real-time safety evaluation of signalized intersections were developed and validated, using traffic video-data of six locations in two Canadian cities. The developed models relate the number of rear-end traffic conflicts, as a surrogate safety measure, to dynamic traffic parameters at the signal cycle level. Several traffic conflict indicators and multiple conflict severity levels were considered. The transferability of the developed models was also investigated and confirmed using additional traffic datasets for two corridors in the United States. Second, a new procedure to integrate the developed real-time safety models with traffic microsimulation models was proposed. The procedure was validated using real-world traffic video data of two signalized intersections in British Columbia. The results showed that the proposed models can predict traffic conflicts from traffic simulation with reasonable accuracy and subsequently can be used to investigate the safety impact of various CVs-based applications before field implementation. Third, a novel self-learning ATSC algorithm to optimize traffic safety using real-time CVs data was proposed. The algorithm was developed using the Reinforcement Learning approach, trained using a microsimulation model, and validated using real-world traffic data of two signalized intersections in British Columbia. Superior to the traditional actuated signal control system, the proposed algorithm showed positive safety and mobility impacts. The proposed ATSC algorithm was also found to be effective and feasible even under low market penetration rates of CVs.

description: Excerpts from the report: Lower U.S. cotton production in recent years, together with declining market price trends and rising costs, have resulted in serious economic problems for many cotton growers. Increased use of synthetics and imported fabrics has displaced cotton in many uses. Growers are looking for ways to increase their net returns from cotton, and a larger share of the textile market. The purpose of this study is to evaluate the opportunities for cotton growers to increase their net incomes from cotton through cooperative action to reduce gin and other costs. The primary gin cost data used in this study came from 32 Arkansas cooperative gins. The relationships, other findings, suggestions, and recommendations on ginning apply specifically to the cooperative gins studied but they also have broad application to similar gins in nearby States. And some of them, such as seasonality, apply to most or all other cooperative gins.

description: Template matching is one of the simplest methods used for eyes and mouth detection. However, it can be modified and extended to become a powerful tool. Since the patch itself plays a significant role in optimizing detection performance, a study on the influence of patch size and shape is carried out. The optimum patch size and shape is determined using the proposed method. Usually, template matching is also combined with other methods in order to improve detection accuracy. Thus, in this paper, the effectiveness of two image processing methods i.e. grayscale and Haar wavelet transform, when used with template matching are analyzed.

description: To shed light on the role of magnetism on the superconducting mechanism of the oxygen-free FeAs pnictides, we investigate the effect of magnetic ordering on phonon dynamics in the low-temperature orthorhombic parent compounds, which present a spin-density wave. The study covers both the 122 (AFe2As2; A=Ca, Sr, Ba) and 1111 (AFeAsF; A=Ca, Sr) phases. We extend our recent work on the Ca (122 and 1111) and Ba (122) cases by treating computationally and experimentally the 122 and 1111 Sr compounds. The effect of magnetic ordering is investigated through detailed non-magnetic and magnetic lattice dynamical calculations. The comparison of the experimental and calculated phonon spectra shows that the magnetic interactions/ordering have to be included in order to reproduce well the measured density of states. This highlights a spin-correlated phonon behavior which is more pronounced than the apparently weak electron-phonon coupling estimated in these materials. Furthermore, there is no noticeable difference between phonon spectra of the 122 Ba and Sr, whereas there are substantial differences when comparing these to CaFe2As2 originating from different aspects of structure and bonding.

description: Il mio Lavoro di Diploma si pone come obiettivo quello di rendere consapevoli gli allievi adolescenti sull’utilizzo corretto dei farmaci, un aspetto di grande rilevanza sociale. Questo percorso è stato pensato per delle classi di seconda liceo. Lo scopo del percorso didattico da me progettato è quello di implementare una cultura scientifica su questo argomento. Il percorso è composto da lezioni classiche che presentano i concetti più importanti e rilevanti su questo tema e da un’attività sperimentale, nella quale si esamina il profilo di dissoluzione di due compresse farmacologiche con lo stesso principio attivo che si disintegrano in sede diverse del nostro corpo e hanno pertanto funzioni terapeutiche differenziate. Attraverso l’apprendimento teorico durante le lezioni in aula, dalla lettura del foglietto illustrativo di un farmaco, e dall’esperienza interdisciplinare di laboratorio, gli allievi possono sviluppare conoscenze e competenze specifiche. L’inserimento di un progetto didattico di farmacologia già in seconda liceo permette di comprendere le relazioni fra i farmaci che si assumono spesso quasi automaticamente e quello che succede all’interno del corpo in seguito all’ingestione del farmaco stesso: le conoscenze acquisite a lezione diventano immediatamente spendibili nella realtà quotidiana e consentono di sviluppare un pensiero critico nella vita di tutti i giorni.

description: Excerpts from the report: During the past decade, dairy farmers moved rapidly into new bargaining activities to provide producers with more adequate incomes. Motivating factors have been depressed milk prices, depressed incomes, and reduced dairy farm numbers. Initially, a number of midwestern milk marketing cooperatives worked together in forming two large federated bargaining associations in the early to mid-1960’s. Then came a sequence of consolidations and mergers within these two federations by local cooperatives, resulting in several multimarket regional cooperatives. These merged regionals in turn became members of their respective federations. The specific objectives of the study were to: 1. Describe the changes which have occurred in the structure of fluid-milk markets in recent years, with emphasis on changes in producer organization. 2. Identify the activities of bargaining organizations in the dairy industry and their relation to bargaining success. 3. Analyze the effect of bargaining groups on milk prices, producer returns, and milk processors. 4. Analyze the implications of bargaining efforts in the dairy industry for producers and their cooperatives in other commodity areas.

description: Based on the method proposed in [ H. S. Zong, W. M. Sun, Phys. Rev. \textbf{D 78}, 054001 (2008)], we calculate the equation of state (EOS) of QCD at zero temperature and finite quark chemical potential under the hard-dense-loop (HDL) approximation. A comparison between the EOS under HDL approximation and the cold, perturbative EOS of QCD proposed by Fraga, Pisarski and Schaffner-Bielich is made. It is found that the pressure under HDL approximation is generally smaller than the perturbative result. In addition, we also calculate the quark number susceptibility (QNS) at finite temperature and finite chemical potential under hard-thermal/dense-loop (HTL/HDL) approximation and compare our results with the corresponding ones in the previous literature.

Implementation leadership characteristics of first-level leaders and nurses' use of mobile health technologies
Creators: name: Ronquillo, Charlene E.
Publisher: name: University of British Columbia
Year: 2021

description: Aims: The purpose of this study was to examine the effects of first-level leaders’ implementation leadership characteristics on nurses’ intention to use and actual use of mHealth in practice while controlling for nurses’ individual characteristics, voluntariness, perceived usefulness, and perceived ease of use of mHealth. Background: The use of mobile technologies in healthcare (mHealth) has increased exponentially since widespread availability of smartphones. Current understanding of nurses’ mHealth use focuses on individual-level factors. There is a need to consider broader contextual factors in shaping mHealth use. One group that may influence nurses’ mHealth use are first-level leaders, individuals who are responsible for implementing mHealth. Drawing from implementation science and informed by the importance of leadership in nursing, this study examined the impact of implementation leadership characteristics of first-level leaders on nurses’ use of mHealth in practice. Method: A cross-sectional exploratory correlational survey study of registered nurses in Canada (N = 288) was conducted between January and June 2018. Nurses were eligible to participate if they provided direct care in any setting and used employer provided mHealth in practice. Hierarchical multiple regression analyses were conducted for the two outcome variables, intention to use and actual use. Results: The implementation leadership characteristics of first-level leaders influenced nurses’ intention to use and actual use of mHealth, with two moderating effects found. Implementation leadership had a greater influence on the intention to use mHealth among nurses with an RN diploma or Bachelor of Nursing as compared to nurses with a Graduate degree. For participants of older ages, implementation leadership had less of an influence on nurses’ actual use of mHealth. Conclusion: Leaders responsible for the implementation of mHealth need to assess and consider their implementation leadership behaviours as these play a role in influencing nurses’ mHealth use. Education level and age of nurses may be important factors to consider as different groups may require varied approaches to optimize nurses’ use of mHealth in practice.

description: This paper explores a variety of strategies for understanding the formation, structure, efficiency and vulnerability of water distribution networks. Water supply systems are studied as spatially organized networks for which the practical applications of abstract evaluation methods are critically evaluated. Empirical data from benchmark networks are used to study the interplay between network structure and operational efficiency, reliability and robustness. Structural measurements are undertaken to quantify properties such as redundancy and optimal-connectivity, herein proposed as constraints in network design optimization problems. The role of the supply-demand structure towards system efficiency is studied and an assessment of the vulnerability to failures based on the disconnection of nodes from the source(s) is undertaken. The absence of conventional degree-based hubs (observed through uncorrelated non-heterogeneous sparse topologies) prompts an alternative approach to studying structural vulnerability based on the identification of network cut-sets and optimal connectivity invariants. A discussion on the scope, limitations and possible future directions of this research is provided.

description: We study the $(k,s)$-positivity for holomorphic vector bundles on compact complex manifolds. $(0,s)$-positivity is exactly the Demailly $s$-positivity and a $(k,1)$-positive line bundle is just a $k$-positive line bundle in the sense of Sommese. In this way we get a unified theory for all kinds of positivities used for semipositive vector bundles. Several new vanishing theorems for $(k,s)$-positive vector bundles are proved and the vanishing theorems for $k$-ample vector bundles on projective algebraic manifolds are generalized to $k$-positive vector bundles on compact Kähler manifolds.

description: The question of Lorentz invariance for finite N approximations of relativistic membranes is addressed. We find that one of the classical manifestations of Lorentz-invariance is not possible for NxN matrices (at least when N=2 or 3). How the symmetry is restored in the large N limit is studied numerically.

description: The electromagnetic form factors are the most fundamental quantities to describe the internal structure of the nucleon and are related to the charge radii of the baryons. We have calculated the charge radii of octet baryons in the framework of chiral constituent quark model with the inclusion of the spin-spin generated configuration mixing. This model is quite successful in predicting the low energy hadron matrix elements. The results obtained in the case of charge radii are also comparable to the latest experimental studies and show improvement over some theoretical interpretations.

description: Excerpts from the report: This report contains information provided and approved by 20 major regional cooperatives. A “regional cooperative” in this report refers to one that: (1) wholesales supplies to local retail cooperatives; (2) directly retails supplies to farmers over an area comprising a part of a State, an entire State, or several States; or performs both functions. A regional also may manufacture some of the supplies it distributes. The first section of this report gives detailed information on 20 of the major regional cooperatives handling supplies for their fiscal years ended in 1968 and 1969, and data on total sales, net margins, and total assets in 1970. Following the individual reports from the 20 associations, a summary is provided which consolidates the detailed information.

description: Background and purpose — Knowledge regarding patient-reported outcomes (PROs) after dislocation and closed reduction is lacking. We report health- and hip-related quality of life (QoL) after dislocation, following primary total hip arthroplasty (THA). Patients and methods — We conducted a cross-sectional study with patients registered in the Danish Hip Arthroplasty Register from 2010 to 2014. Dislocations were captured based on diagnosis/procedure codes and patient file reviews. Patients with dislocation were matched 1:2, according to age, sex, date, and hospital of primary surgery, to patients without dislocation. 2 PRO questionnaires were applied (EQ-5D, HOOS). Results — We identified 1,010 living patients with dislocation. Mean follow-up was 7.2 years from index surgery and 4.9 years (range 0.6–9.7) from the latest dislocation. Patients without dislocation reported a higher EQ VAS score of 76 (95% CI 75–77) compared with 68 (CI 66–70) for the dislocation group. The EQ-5D-5L mean index score was 0.89 (CI 0.88–0.90) for the control group, compared with 0.78 (CI 0.76–0.80) for the cases with dislocation without revision. Patients with dislocation reported a lower HOOS-QoL domain score of 63 (CI 60–65), compared with 83 (CI 82–84) for the control group. Even 5 years after the latest dislocation, the HOOS-QoL score remained low, at 66 (CI 62–69). The other HOOS domains were consistently 8–10 points worse after dislocation. Interpretation — Both health- and hip-related QoL were markedly and persistently reduced among dislocation patients compared with those in controls, for several years. Therefore, the avoidance of the initial dislocation episode is important because the THA does not appear to achieve the full relieving potential.

description: Adopting the convection-diffusion model for energetic electron and proton propagation, and accounting for all the relevant hadronic and leptonic processes, the steady-state energy distributions of these particles in the starburst galaxies M82 and NGC253 can be determined with a detailed numerical treatment. The electron distribution is directly normalized by the measured synchrotron radio emission from the central starburst region; a commonly expected theoretical relation is then used to normalize the proton spectrum in this region, and a radial profile is assumed for the magnetic field. The resulting radiative yields of electrons and protons are calculated: the predicted >100MeV and >100GeV fluxes are in agreement with the corresponding quantities measured with the orbiting Fermi telescope and the ground-based VERITAS and HESS Cherenkov telescopes. The cosmic-ray energy densities in central regions of starburst galaxies, as inferred from the radio and gamma-ray measurements of (respectively) non-thermal synchrotron and neutral-pion-decay emission, are U=O(100) eV/cm3, i.e. at least an order of magnitude larger than near the Galactic center and in other non-very-actively star-forming galaxies. These very different energy density levels reflect a similar disparity in the respective supernova rates in the two environments. A L(gamma) ~ SFR^(1.4) relationship is then predicted, in agreement with preliminary observational evidence.

description: Herein, Keggin-type heteropolyacid (SiMo12) supported on magnetic polythiophene nanocomposite has been successfully synthesized. The obtained Fe3O4@SiO2@PT\SiMo12 magnetic nanocomposite has been characterized by XRD, FESEM and the relating XEDS energy mapping, UV–vis DRS, ICP-MS, and VSM. The catalytic and photocatalytic oxidative desulfurization (ODS) activities of the synthesized nanocatalysts were studied with T, BT, and DBT as the model sulfur compounds. Results showed that the Fe3O4@SiO2@PT\SiMo12 nanocatalyst exhibited significantly higher catalytic and photocatalytic ODS activities than pure SiMo12, PT, and Fe3O4@SiO2@PT at the same experimental conditions. In general, Fe3O4@SiO2@PT\SiMo12 showed higher photocatalytic ODS (under visible light) activity (97.2%, 99% and 99.7%) than catalytic ODS (87%, 89.6% and 96.2%) for T, BT, and DBT respectively after 45 min. Also, the Fe3O4@SiO2@PT\SiMo12 nanocatalyst possessed excellent stability after five reaction cycles.

description: The Frenkel Kontorova (FK) model is known to exhibit the so called Aubry's transition which is a jamming or frictional transition at zero temperature. Recently we found similar transition at zero and finite temperatures in a super-conducting Josephson junction array (JJA) on a square lattice under external magnetic field. In the present paper we discuss how these problems are related.

description: In the present work, the adsorption of H2S, SO2, and SO3 on the B36 surface was investigated by the density functional theory (DFT) method. The adsorption energy, geometrical parameters, thermodynamics quantities, electronic properties, state density, charge analysis, and chemical indices were calculated to describe sulfur-containing gases’ adsorption behavior. The most stable adsorption configurations of SO2 and SO3, of which O atoms bond to edge B atoms of the B36 surface, were found. These configurations of most stable adsorptions of SO2 and SO3 on the B36 surface are thermodynamically preferred, but H2S adsorbed on the B36 surface is non–spontaneous adsorption. The most potent adsorption energies of H2S, SO2, and SO3 on the B36 surface are −5.29, −43.85, and −80.57 kcal/mol, respectively. The B36 nanocluster has a high potential to be used as SO2 and SO3 storage and SO2 sensing material.
