description: The issue of gully erosion is of major concern in the South-eastern part of Nigeria. The vegetation in the area is steadily being degraded thereby exposing the soil to erosion, especially the gully type. This feature is not only increasing in occurrence but also in magnitude. Large areas of agricultural lands are lost or have become unsuitable for cultivation due to gully erosion. There have been numerous attempts to curb gully erosion in the region; especially through large-scale engineering projects, however, little has been discussed about ways to prevent their onset or the use of community-based low-technology approaches to mitigate their development. The possibility of climate change playing a role in this has not been given the deserved attention. This paper therefore examined the extent the climate of Southeastern Nigeria is changing and its implication in soil erosion occurrence and magnitude. The method adopted was observation of some gully erosion sites in the area, interview with key stakeholders and review of relevant literature. Findings showed that there has been an upward trend in annual mean temperature and rainfall in the area. It also revealed that many eroding gullies in the region are human induced and therefore can be prevented. The gullies can be traced to poor land management practices and to a lack of innovation and awareness measures. It was concluded that community-based, low technology land management practices and public awareness programs through workshops as well as concerted efforts by governments at all levels could halt the development of many gullies in the South Eastern region of Nigeria.

description: Several steps are missing in the current high-speed race towards the holistic support of citizen needs in the domain of eGovernment. This paper is focused on how to provide support for the citizen profile. This profile, in a wide sense, includes personal information as well documents in possession of the citizen. This also involves the provision of those mechanisms required to publish, access and submit the convenient information to a Public Administration in due curse of a transactional services provided with the last one. Main features of the system are related to interoperability and possibilities for its inclusion in a cost effective manner in already developed platforms. To make that possible, this approach will take full advantage of semantic technologies and the RESTful paradigm to design the entire system. The paper presents the overall system with some notes on the deployment of the solution for its further reuse in similar contexts.

description: We present a galaxy group-finding algorithm, the Photo-z Probability Peaks (P3) algorithm, optimized for locating small galaxy groups using photometric redshift data by searching for peaks in the signal-to-noise of the local overdensity of galaxies in a three-dimensional grid. This method is an improvement over similar two-dimensional matched-filter methods in reducing background contamination through the use of redshift information, allowing it to accurately detect groups at lower richness. We present the results of tests of our algorithm on galaxy catalogues from the Millennium Simulation. Using a minimum S/N of 3 for detected groups, a group aperture size of 0.25 Mpc/h, and assuming photometric redshift accuracy of sigma_z = 0.05 it attains a purity of 84% and detects ~295 groups/deg.^2 with an average group richness of 8.6 members. Assuming photometric redshift accuracy of sigma_z = 0.02, it attains a purity of 97% and detects ~143 groups/deg.^2 with an average group richness of 12.5 members. We also test our algorithm on data available for the COSMOS field and the presently-available fields from the CFHTLS-Wide survey, presenting preliminary results of this analysis.

description: The object of the study - a four-level quantum system. The purpose of this work - to study theoretically the propagation of two- frequency radiation under conditions of coherent population trapping resonance in a closed excitation contour. In this paper, we study the interaction of an optically dense atomic ensemble with two-frequency laser radiation, which has four possible energy levels, under the condition of a closed excitation scheme. As a result of the study, a mathematical model was constructed, a system of equations for the density matrix was obtained, its numerical solution was performed, and the results were analyzed.
The targum (1884:Dec. 12)
Creators: name: No Name Supplied
Publisher: name: Targum Association
Year: 1884

description: Some University historians indicate that the Targum was first published as an annual in 1867, but of this we have no extant evidence. In January 1869, the Targum as we now know it, made its appearance as a monthly paper that concerned itself with student “literary contributions” and college news as well as serving as a vehicle for bringing news to alumni and the general public. The newspaper, which originally was for sale, varied in frequency over the years as did its title (The Targum, Rutgers Targum, Rutgers Daily Targum, and Daily Targum). The newspaper has continuously been published since 1869 with the exception of 19 months during the second world war, between February 1944 and October 1945. The Targum was published by the students of Rutgers College, and later Rutgers University—New Brunswick represented through the years as the Targum Association, Rutgers Targum Association, and Rutgers College Targum. As a student organization, the Targum operated under the oversight of the dean of students and student government but in October 1980, the Targum became an independent college paper.
Understanding communities of support for resettled refugee children and their families : a strengths-based study of partnership in Metro Vancouver
Creators: name: Goossen, Rachel
Publisher: name: University of British Columbia
Year: 2019

description: Public schools fill a unique space in the settlement landscape, often serving as a first point of community-based contact for newcomers to Canada. Inspired by characteristics of appreciative inquiry as methodology, this qualitative study takes a strengths-based approach to examine the roles—both present and potential—of public schools in supporting refugee resettlement. Using a singular partnership between a service-providing organization (SPO) and a public primary school in Metro Vancouver, I explore the policies and practices where support of both refugee students and their families is encouraged and nurtured at the K–12 school level. School districts across British Columbia and Canada continue to take various innovative approaches to support newcomers, and specifically refugees, in their schools and communities. However, limited research has been done in the Canadian context to assess and collate best practices where refugee students are supported holistically, and in relation to the broader settlement service sector. Research methods include interviews conducted with key administrators at the school and district levels as well as staff in the SPO, nested in the context of relevant municipal and provincial policy documents. I suggest essential characteristics of program design and practice that promote integration of refugee students and families in the community, as well as considerations for future research to grow our understanding of the critical role of public schools in refugee resettlement and support in Canada.

description: Resource competition is a fundamental interaction in natural communities.However little is known about competition in spatial environments where organisms are able to regulate resource distributions. Here, we analyze the competition of two consumers for two resources in a one-dimensional habitat in which the resources are supplied from opposite sides. We show that the success of an invading species crucially depends on the slope of the resource gradients shaped by the resident. Our analysis reveals that parameter combinations which lead to coexistence in a uniform environment may favor alternative stable states in a spatial system, and vice versa. Furthermore, differences in growth rate, mortality or dispersal abilities allow a consumer to coexist stationarily with - or even outcompete - a competitor with lower resource requirements. Applying our theory to a phytoplankton model, we explain shifts in the community structure that are induced by environmental changes.
Sub-linear radiation power dependence of photo-excited resistance oscillations in two-dimensional electron systems

description: We find that the amplitude of the $R_{xx}$ radiation-induced magnetoresistance oscillations in GaAs/AlGaAs system grows nonlinearly as $A \propto P^α$ where $A$ is the amplitude and the exponent $α< 1$. %, with $α\rightarrow 1/2$ in %the low temperature limit. This striking result can be explained with the radiation-driven electron orbits model, which suggests that the amplitude of resistance oscillations depends linearly on the radiation electric field, and therefore on the square root of the power, $P$. We also study how this sub-linear power law varies with lattice temperature and radiation frequency.

We reexamine both the single component and the binary mixture cases for such a potential, and we investigate in which situations a simpler two-mode approach leads to an accurate description of their dynamics. We also estimate the validity of the most usual dimensionality reductions used to solve the Gross-Pitaevskii equations. To this end, we compare both the semi-analytical two-mode approaches and the numerical simulations of the 1D reductions with the full 3D numerical solutions of the Gross-Pitaevskii equation. Our analysis provides a guide to clarify the validity of several simplified models that describe mean field non-linear dynamics, using an experimentally feasible binary mixture of an F=1 spinor condensate with two of its Zeeman manifolds populated, m=+1 and m=-1.

description: In conventional superconductors, magnetic impurities form an impurity band due to quantum interference of the impurity bound states, leading to suppression of the superconducting transition temperature. Such quantum interference effects can also be expected in d-wave superconductors. Here, we use scanning tunneling microscopy to investigate the effect of multiple non-magnetic impurities on the local electronic structure of the high-temperature superconductor Bi$_{2}$Sr$_{2}$Ca(Cu$_{1-x}$Zn$_{x}$)$_{2}$O$_{8+δ}$. We find several fingerprints of quantum interference of the impurity bound states including: (i) a two-dimensional modulation of local density-of-states with a period of approximately 5.4 Å along the $a$- and $b$-axes, which is indicative of the d-wave superconducting nature of the cuprates; (ii) abrupt spatial variations of the impurity bound state energy; (iii)an appearance of positive energy states; (iv) a split of the impurity bound state. All of these findings provide important insight into how the impurity band in d-wave superconductors is formed.

description: The paper explored how agriculture can be made more attractive for youth employment for attainment of economic diversification in an oil-based economy. It took a quick x-ray of the nation’s agricultural policies vis-à-vis youth employment in agriculture, identified some challenges militating against youth interestedness in agriculture and proffered workable solutions that could drive youth interest in agriculture. It is argued that, agriculture should be promoted as a sustainable livelihood source and as an initial entry point to propel Nigeria into a green economy where there is inclusivity and equity, resource use efficiency and minimal environmental risks in line with United Nations (UN) Post-2015 Sustainable Development Goals. In an era where the world economies are driven by knowledge, integration of information and communication technologies (ICTs) and agro-tourism into agricultural activities as obtainable in any truly business venture will make agriculture attractive to the youth. Positive changes in the way we consider the youth as mere beneficiaries of agricultural interventions to seeing them as co-actors/players in the agriculture space and along the e-agriculture value chain will lead to improved agricultural productivity. The use of ICT and promoting establishment of functional Agribusiness Incubators in strategically selected Nigerian universities is needed. Agricultural policy reforms that support training youth farmers and prospective ones as impact entrepreneurs will engender youth involvement in agriculture, give them a sense of ownership and protection from unfavourable policies including subsidies that, apparently, restrict or even hinder youth involvement.

description: A brief review of works on the microscopic theory of determining the upper critical field in two-band isotropic and anisotropic superconductors is given. The research is based on a set of the Ginzburg-Landau equations for the order parameters in a magnetic field that are studied in terms of the classical approach to a superconducting system in a magnetic field. Two inequivalent energy bands with different topology of Fermi surface cavities overlapping on the Fermi surface are discussed. The cases of the direction of the external magnetic field H\to// the (ab) plane and H\to // the crystallographic c axis are studied. The equations for determining Hc2(ab) and Hc2(c) for a pure superconductor and a superconductor doped with electrons and holes are derived.

description: The initial condition of young open star clusters provides important information to understand how star forms. However, we carried out star-by-star N-body models using PeTar and found that if OB stars randomly form, the fate of star clusters become unpredictable. The rich kinetical data from Gaia can help to identify the tidal streams of clusters, which can better constrain the initial OB content and improve our understanding of the nature of initial mass function.

description: The β decays of very neutron-rich nuclides in the Co-Zn region were studied experimentally at the National Superconducting Cyclotron Laboratory using the NSCL β-counting station in conjunction with the neutron detector NERO. We measured the branchings for β-delayed neutron emission (Pn values) for 74Co (18 +/- 15%) and 75-77Ni (10 +/- 2.8%, 14 +/- 3.6%, and 30 +/- 24%, respectively) for the first time, and remeasured the Pn values of 77-79Cu, 79,81Zn, and 82Ga. For 77-79Cu and for 81Zn we obtain significantly larger Pn values compared to previous work. While the new half-lives for the Ni isotopes from this experiment had been reported before, we present here in addition the first half-life measurements of 75Co (30 +/- 11 ms) and 80Cu (170+110 -50 ms). Our results are compared with theoretical predictions, and their impact on various types of models for the astrophysical rapid neutron-capture process (r-process) is explored. We find that with our new data, the classical r-process model is better able to reproduce the A = 78-80 abundance pattern inferred from the solar abundances. The new data also influence r-process models based on the neutrino-driven high-entropy winds in core collapse supernovae.

description: We study the exchange interaction $J$ between two magnetic impurities in graphene (the RKKY interaction) by directly computing the lattice Green's function for the tight-binding band structure for the honeycomb lattice. The method allows us to compute $J$ numerically for much larger distances than can be handled by finite-lattice calculations as well as for small distances. % avoids the use of a cutoff function often invoked in the literature to curtail the diverging contributions from the linear bands and yields results that are valid for all distances. In addition, we rederive the analytical long-distance behavior of $J$ for linearly dispersive bands and find corrections to the oscillatory factor that were previously missed in the literature. The main features of the RKKY interaction in graphene are that unlike the $J \propto (2k_FR)^{-2} \sin (2k_FR) $ behavior of an ordinary 2D metal in the long-distance limit, $J$ in graphene falls off as $1/R^3$, shows the $1 + \cos ((K-K').R)$-type oscillations with additional phase factors depending on the direction, and exhibits a ferromagnetic interaction for moments on the same sublattice and an antiferromagnetic interaction for moments on the opposite sublattices as required by particle-hole symmetry. The computed $J$ with the full band structure agrees with our analytical results in the long-distance limit including the oscillatory factors with the additional phases.

Star clusters and associations

description: Young associations provide a star formation record that can be used to uncover the mechanisms of star formation across large scales in space and time. Through the SPYGLASS program, we use Gaia photometry and astrometry to identify young stars and the associations they reside in, the initial findings of which have recently been published. Updated data provided by Gaia EDR3 has allowed us to begin expanding our work, revealing smaller and more distant structures. In this poster, we summarize past results and provide updates on the discoveries of the SPYGLASS program, while revealing new active projects to deepen our knowledge in the clusters and associations already discovered.
Site specific heterogeneous catalysis : CO and C₂H₄ bonding with Fe-Terpyridine on a Ag(111) surface studied by scanning probe microscopy
Creators: name: DeJong, Miriam Dieneke
Publisher: name: University of British Columbia
Year: 2019

description: Heterogeneous catalysis is a key process in the manufacturing of chemicals, clean fuels, plastics, and pharmaceuticals, and often involves gaseous reactants catalyzed by solid surfaces producing gaseous products. At the solid-gas interface, a variety of potential nucleation sites and reaction pathways for chemical transformations exist. To track these different pathways and distinguish the main reaction from side reactions, it is essential to explore the surface site-by-site, at the atomic scale. Experimental techniques offering the ability to probe surfaces on a site- specific, atomic scale are limited, and rigorous knowledge of reaction mechanisms in many heterogeneous catalysis processes is lacking. In this work, Scanning Probe Microscopy (SPM) techniques including Scanning Tunneling Microscopy (STM), Scanning Tunneling Spectroscopy (STS), and non contact Atomic Force Microscopy (ncAFM) were utilized to examine the site-by-site surface transformation of small gaseous adsorbates at the single-molecule and submolecular scales. SPM techniques are able to access site-specific information from surfaces on the atomic scale, which is vital to elucidating reaction mechanisms in heterogeneous catalysis. For this work, an Fe-terpyridine coordination complex supported on a Ag(111) surface was tested as a catalyst for the transformation of gaseous carbon monoxide (CO) and ethylene (C₂H₄). Using SPM techniques, bonding was measured between CO and Fe-terpyridine active sites, and between C₂H₄ and the active sites at temperatures of T ≤ 30K. Physical structural changes in ncAFM and STM images as well as shifts in electronic structure obtained through STS measurements were used to characterize the bonds, and both Fe-CO and Fe-C₂H₄ bonds were preceded by metastable reaction intermediates. The measured bonding activity presented in this work demonstrates the potential of surface-supported Fe-terpyridine complexes as catalysts in the transformation of small hydrocarbons and oxides, and the fundamental mechanistic insight obtained through this SPM investigation opens the door to future optimization of these heterogeneous transformations.
An $\varepsilon$-regularity Theorem For The Mean Curvature Flow

description: In this paper, we will derive a small energy regularity theorem for the mean curvature flow of arbitrary dimension and codimension. It says that if the parabolic integral of $|A|^2$ around a point in space-time is small, then the mean curvature flow cannot develop singularity at this point. As an application, we can prove that the 2-dimensional Hausdorff measure of the singular set of the mean curvature flow from a surface to a Riemannian manifold must be zero.
Universal intrinsic doping behavior of in-plane dc conductivity for hole-doped high-temperature cuprate superconductors

description: Understanding the normal state transport properties in hole-doped high-temperature cuprate superconductors (HTCSs) is a challenging task which has been widely believed to be one of the key steps toward revealing the pairing mechanism of high-temperature superconductivity. Here, we present a true intrinsic and universal doping dependence of in-plane dc conductivity for all underdoped HTCSs. The doping dependence of in-plane dc conductivity normalized to that at optimal doping can be represented by a simple exponential formula. The doping behavior of the square of the nodal Fermi velocity derived by the high-resolution laser-based angle-resolved photoemission spectroscopy in the superconducting state follows reasonably well the universal intrinsic doping behavior. Our findings suggest a commonality of the low-energy quasiparticles both in the normal and superconducting states that place a true universal and stringent constraint on the mechanism of high-temperature superconductivity for HTCSs.

The contribution of N-rich stars to the Galactic stellar halo using APOGEE red giants

description: The contribution of dissolved globular clusters (GCs) to the stellar content of the Galactic halo is a key constraint on models for GC formation and destruction, and the mass assembly history of the Milky Way. Earlier results from APOGEE pointed to a large contribution of destroyed GCs to the stellar content of the inner halo, by as much as 25 per cent per cent , which is an order of magnitude larger than previous estimates for more distant regions of the halo. We set out to measure the ratio between nitrogen-rich (N-rich) and normal halo field stars, as a function of distance, by performing density modelling of halo field populations in APOGEE DR16. Our results show that at 1.5 kpc from the Galactic Centre, N-rich stars contribute a much higher 16.8 +10.0−7.0 per cent−7.0+10.0 per cent fraction to the total stellar halo mass budget than the 2.7 +1.0−0.8 per cent−0.8+1.0 per cent ratio contributed at 10 kpc. Under the assumption that N-rich stars are former GC members that now reside in the stellar halo field, and assuming the ratio between first and second population GC stars being 1:2, we estimate a total contribution from disrupted GC stars of the order of 27.5 +15.4−11.5 per cent−11.5+15.4 per cent at r = 1.5 kpc and 4.2 +1.5−1.3 per cent−1.3+1.5 per cent at r = 10 kpc. Furthermore, since our methodology requires fitting a density model to the stellar halo, we integrate such density within a spherical shell from 1.5 to 15 kpc in radius, and find a total stellar mass arising from dissolved and/or evaporated GCs of MGC,total = 9.6 +4.0−2.6×−2.6+4.0× 107M⊙.
Highly under-expanded jets in the presence of a transverse density gradient

description: An experimental research concerning highly underexpanded jets made of different gases from the surrounding ambient is here described. By selecting different species of gases, it was possible to vary the jet-to-ambient density ratio in the 0.04 to 12 range and observe its effect on the jet morphology. By adjusting the stagnation and ambient pressures, it has been possible to select the Mach number of the jets, independently from the density ratio. Each jet is therefore characterized by its maximum Mach number, ranging from 10 to 50. The Reynolds number range of the nozzle is 1000 to 50000. The spatial evolution of the jets was observed over a much larger scale than the nozzle diameter. The gas densities were evaluated from the light emission induced by an electron beam and the gas concentrations were obtained by analyzing the color of the emitted light. The results have shown that the morphology of the jets depends to a greater extent on the density ratio. Jets that are lighter than the ambient exhibit a more intense jet-ambient mixing than jets that are heavier than the ambient, while the effects of changing the jet Mach number do not seem to be too large in the explored range. These results can be expressed by means of two simple scaling laws relevant to the near field (pre-Mach-disk) and the mid-long term field (post-Mach-disk), respectively.
Circulation and upwelling in Mackenzie Canyon, a dynamically wide submarine canyon in the Beaufort Sea
Creators: name: Machuca, Idalia Alicia
Publisher: name: University of British Columbia
Year: 2019

description: Mackenzie Canyon, in the southeastern Beaufort Sea, is a site for strong upwelling compared to the adjacent continental shelf and slope and potentially supplies the shelf with significant levels of nitrate. Research regarding the circulation and upwelling mechanisms in submarine canyons has previously been limited to dynamically narrow canyons, and most studies have used numerical models with idealized bathymetry. The main goal of the study presented in this thesis is to describe the circulation and upwelling in Mackenzie Canyon, which is classified as a dynamically wide canyon. This study also identifies key flow features that act as significant modifiers of upwelling, examines differences between idealized and realistic model simulations, and estimates the canyon-induced upwelling of nitrate. To address these goals, the circulation and upwelling associated with an upwelling event induced by an impulsive wind forcing in Mackenzie Canyon was simulated using a nested-grid modelling system configuration based on the Nucleus for European Modelling of the Ocean framework. Numerical simulations were conducted using realistic and idealized bathymetry and three cases of wind stress forcing. The model performance was evaluated using observational data from Mackenzie Canyon during an upwelling event. This study finds that near-geostrophic flows are topographically steered around the Mackenzie Canyon walls. Strong cyclonic vorticity is generated on the upstream corner of the canyon mouth and evolves into a closed, cyclonic eddy, which becomes a site for strong upwelling. A coastal trapped wave (CTW) is induced on the downstream side of the canyon and propagates upstream. It is characterized as a shelf wave using a model that searches for the free wave solutions of CTWs along straight coastlines. An upwelling signal in the canyon exits the canyon and propagates along the slope with the CTW. Unlike narrow canyons, upwelling in Mackenzie Canyon is stronger on the upstream side than on the downstream side, likely as a consequence of the upstream propagation of the CTW. The nitrate flux across the nitracline depth supplied by upwelling in Mackenzie Canyon during the initial 36 hours of an upwelling event is estimated to be twice the seasonal draw-down in the Beaufort Sea.

description: We obtained mid-infrared 3.6 and 4.5 micron imaging of a z=6.96 Lyman alpha emitter (LAE) IOK-1 discovered in the Subaru Deep Field, using Spitzer Space Telescope Infrared Array Camera observations. After removal of a nearby bright source, we find that IOK-1 is not significantly detected in any of these infrared bands to m_3.6 ~ 24.00 and m_4.5 ~ 23.54 at 3 sigma. Fitting population synthesis models to the spectral energy distribution consisting of the upper limit fluxes of the optical to infrared non-detection images and fluxes in detection images, we constrain the stellar mass M* of IOK-1. This LAE could have either a mass as low as M* 100 Myr) or the high dust reddening (A_V ~ 1.5). This would be within the range of masses of z ~ 3-6.6 LAEs studied to date, ~ 10^6-10^{10} Msun. Hence, IOK-1 is not a particularly unique galaxy with extremely high mass or low mass but is similar to one of the LAEs seen at the later epochs.

description: In 2006, Suzuki, and Akbari & Alipour independently presented a necessary and sufficient condition for edge-colored graphs to have a heterochromatic spanning tree, where a heterochromatic spanning tree is a spanning tree whose edges have distinct colors. In this paper, we propose $f$-chromatic graphs as a generalization of heterochromatic graphs. An edge-colored graph is $f$-chromatic if each color $c$ appears on at most $f(c)$ edges. We also present a necessary and sufficient condition for edge-colored graphs to have an $f$-chromatic spanning forest with exactly $m$ components. Moreover, using this criterion, we show that a $g$-chromatic graph $G$ of order $n$ with $|E(G)|>\binom{n-m}{2}$ has an $f$-chromatic spanning forest with exactly $m$ ($1 \le m \le n-1$) components if $g(c) \le \frac{|E(G)|}{n-m}f(c)$ for any color $c$.
