description: In this white paper (WP), we highlight several examples of small and moderate aperture telescopes that are being used for education and/or research. We further discuss potential costs for establishing new, small observatories, as well as joining existing international consortia. The WP includes a brief overview of select observing sites, with a discussion on how small telescopes at exceptional observing locations can be competitive, under certain circumstances, with larger and more expensive facilities located at poorer sites. In addition to research, these facilities enable many different types of educational experiences for wide range of people, from high school students to undergraduates to graduate students to postdocs. Canada should remain committed to partnering with large, international observatories such as CFHT, Gemini, and TMT, but it should also negotiate international agreements and commit funding to expand the use of small and moderate research observatories at domestic and international sites through coordination with the NRC, the Tri-Council, and the Canadian Foundation for Innovation. Both capital and operational costs (with site rental costs allowed) need to be included in support possibilities. CASCA should establish and maintain a small to moderate telescope expression of interest database that would help to facilitate Canadian institutions in organizing consortia, particularly for smaller institutions. The astronomical community should work with the NRC to make existing facilities more accessible to the astronomical community for research. This could involve, for example, automating the Plaskett and/or providing travel funds for supporting classical observing modes. Finally, a small to moderate aperture facility in the Arctic would be a world-class observatory and should be advanced over the next decade.

description: An ultra-wide bandwidth (UWB) remote-powered positioning system for potential use in tracking floating objects inside space stations is presented. It makes use of battery-less tags that are powered-up and addressed through wireless power transfer in the UHF band and embed an energy efficient pulse generator in the 3-5 GHz UWB band. The system has been mounted on the ESA Mars Rover prototype to demonstrate its functionality and performance. Experimental results show the feasibility of centimeter-level localization accuracy at distances larger than 10 meters, with the capability of determining the position of multiple tags using a 2W-ERP power source in the UHF RFID frequency band.

title: Shared Facilities, School and Community: Practice and Implications.
Creators: name: Young, Ian William
Publisher: name: The Open University
Year: 1981

description: "Shared Facilities" - an exciting educational experience ora political manoeuvre for economic expediency? In the fifty years since Henry Morris promoted the concept of opening the school to the community, his idea has been interpreted in many forms. This research was intended to examine the various methods used in England and Wales to implement the philosophy of "shared use" of school premises. The examination of the schemes in operation shows their varying characteristics according to the local authorities' individual interpretations of the concept of the community school. Apart from a fairly extensive system of Community Colleges in Cambridgeshire, a legacy of Henry Morris, community schools were not widely developed until the Plowden Commission Report on Primary Education (1967) recommended that the idea of community schools should be promoted as part of an attempt to involve parents more closely in the education of their children. Plowden asserted the importance of discovering ways of linking home and school and of gaining the understanding and support of parents through an active involvement with the school rather than a passive acceptance of the school’s policies. This need was felt to be greatest in "educational priority areas", i.e. areas with poor housing and social conditions. L.E.As were further encouraged to consider the establishment of community schools in the Ministry Circular 2/70, "A Chance to Share". One interpretation of "community school" is that of "shared use", i.e. opening the school premises and facilities to the wider community. In the investigation an attempt will be made to discover whether "shared use" does encourage parents to become involved in the education of their children through their increased contact with the school. The investigations at Boldon and Hedworthfield were an attempt to discover whether parental contact with the school through "shared use" significantly benefited child and school. Following a pilot survey conducted at Hedworthfield School, the Boldon survey included a questionnaire to parents of pupils in the school, observation of the scheme in operation, discussions with participants and a thorough investigation of all the literature pertaining to the inception of the scheme.

description: This study’s purpose is to create and improve inclusivity and participation with the University of British Columbia Aquatics Centre located on the Vancouver campus, by discovering the perceived barriers and facilitators students experience. By using an online survey, we identify student participation levels within the Vancouver Aquatics Centre, barriers to students that hinder participation, as well as facilitators that encourage the activity levels within the Aquatics Centre. The survey consisted of 13 questions in a clear and easy to read format and was distributed to students with hand sanitizers given out as incentives for completion of the survey. The goal of this study is to foster wellbeing within students as well as provide inclusive campus facilities that will ultimately generate resilient communities within undergraduate students. By removing barriers, we hope to instill active lifelong practices for students as well as create opportunities for friendships to foster leading to a stronger network as well as improving the UBC campus. Analysis of the data was conducted by the researchers and appropriate recommendations were made to address the main perceived barriers. The three largest barriers to students is the: lack of awareness of programs and offerings at the Aquatics Centre, this includes knowledge of accessing and registering for programs, the second barrier identified it the inadequate registration times, and the third barrier was the prices for attending programs other than a drop in swim. Our recommendations for removing these perceived barriers are create an easily accessible and distributable marketing campaign on the Aquatics Centre and their services, adjust registration times to be compatible with class schedules, and offer a greater discount on classes students are interested in rather than classes associated with older individuals like aquafit.

description: Using historical yield and rainfall data from three university-managed ranches in Kansas and Nebraska, we measure basis risk of Rainfall Index Insurance for Pasture, Rangeland, and Forage (PRF-RI). We investigate the relationship between forage yield and monthly precipitation and estimate the relationship between forage yield and PRF-RI indices. Finally, we estimate basis risk of PRF-RI. Our estimates suggest that using actual site-level precipitation values would reduce basis risk by only 5%–9%, indicating that basis risk stems mostly from nonprecipitation factors. Using more flexible contract forms with site-level precipitation would have little impact on decreasing the degree of basis risk.

description: Human conversations contain many types of information, e.g., knowledge, common sense, and language habits. In this paper, we propose a conversational word embedding method named PR-Embedding, which utilizes the conversation pairs $ \left\langle{post, reply} \right\rangle$ to learn word embedding. Different from previous works, PR-Embedding uses the vectors from two different semantic spaces to represent the words in post and reply. To catch the information among the pair, we first introduce the word alignment model from statistical machine translation to generate the cross-sentence window, then train the embedding on word-level and sentence-level. We evaluate the method on single-turn and multi-turn response selection tasks for retrieval-based dialog systems. The experiment results show that PR-Embedding can improve the quality of the selected response. PR-Embedding source code is available at https://github.com/wtma/PR-Embedding

description: We consider the problem of cotangent bundle reduction for non free group actions at zero momentum. We show that in this context the symplectic stratification obtained by Sjamaar and Lerman refines in two ways: (i) each symplectic stratum admits a stratification which we call the secondary stratification with two distinct types of pieces, one of which is open and dense and symplectomorphic to a cotangent bundle; (ii) the reduced space at zero momentum admits a finer stratification than the symplectic one into pieces that are coisotropic in their respective symplectic strata.

description: Groundwater is a valuable input to agricultural production in many areas, but its use imposes external costs on nearby producers. Little attention has been given to externalities that directly affect groundwater productivity. We develop a dynamic, spatially-explicit model of groundwater use that allows changes in saturated thickness to affect both the pumping cost and productivity of nearby wells.We compare gains from coordinated, socially optimal groundwater use to those that result from a user pursuing unilateral optimization. For wells with average saturated thickness, both unilateral and coordinated optimization can moderately increase the net present value of resource rents.

Further assume $G$ splits over $H$ with hyperbolic vertex and edge groups and the two inclusions of $H$ are quasi-isometric embeddings. Then $H$ is quasiconvex in $G$. This answers a question of Swarup and provides a partial converse to the main theorem of \cite{GMRS}.

description: The most important cool season grain legumes (dry pea, chickpea, broad bean, lentil, lupins, grass pea and common vetch) are widely grown in many parts of the world. The aim of the current study was to test some of them under the drought-prone area of Sadovo (south-central region of Bulgaria) and to evaluate their adaptability based on physiological and agro-biological traits. The investigation was carried out at the experimental field of IPGR including several local accessions of white lupin (Lupinus albus L.), chickpea (Cicer arietinum L.) and grass pea (Lathyrus sativum L.). The chlorophyll content index of the leaves, used as criteria for drought tolerance, was measured by portable CCM 200 plus- Chlorophyll Content Meter. The assessment of agro-biological traits was performed according to the International Descriptor for each crop. Under the drought stress conditions the highest value of the chlorophyll content index was observed in three lupin accessions (BGR 6341, BGR3080, BGR3085), in two from chickpea (BGR 40417 and B9E0149) and in four from grass pea (BGR 40415, BGR 4835, BGR4847, BGR4834). The highest yield potential was established in two lupin (BGR 6341 and BGR 3084), two chickpea accessions (BGR 23151 and B9E0149) and three grass pea (BGR4832 and BGR40415). The selected accessions were included in the list for further investigations concerning drought tolerance and maintenance of relatively high yield potential under drought stress conditions.

description: The SPI instrument has been launched on-board the INTEGRAL observatory on October 17, 2002. SPI is a spectrometer devoted to the sky observation in the 20 keV-8 MeV energy range using 19 germanium detectors. The performance of the cryogenic system is nominal and allows to cool the 19 kg of germanium down to 85 K with a comfortable margin. The energy resolution of the whole camera is 2.5 keV at 1.1 MeV. This resolution degrades with time due to particle irradiation in space. We show that the annealing process allows the recovery of the initial performance. The anticoincidence shield works as expected, with a low threshold at 75 keV, reducing the GeD background by a factor of 20. The digital front-end electronics system allows the perfect alignement in time of all the signals as well as the optimisation of the dead time (12%). We demonstrate that SPI is able to map regions as complex as the galactic plane. The obtained spectrum of the Crab nebula validates the present version of our response matrix. The 3 $σ$ sensitivity of the instrument at 1 MeV is 8 10$^{-7}$ph$\cdot$cm$^{-2}\cdot$s$^{-1}\cdot$keV$^{-1}$ for the continuum and 3 10$^{-5}$ph$\cdot$cm$^{-2}\cdot$s$^{-1}$ for narrow lines.

title: Secondary school realities
Creators: name: Woods, Peter E
Publisher: name: The Open University
Year: 1979

description: This is a symbolic interactionist account of certain aspects of life in a rural Secondary Modern School. A study of its subject choice system suggested two broad group perspectives among the pupils, one supportive of, the other rather indifferent towards school. These perspectives were reflected among the parents to some degree, along social class lines. There was considerable teacher direction, behind a rhetoric of choice. The many-sided nature of pupils' interests and reactions among curriculum, school and teachers was revealed. Three major categories of pupils’ existence ere examined — ’working’, ’having a laugh’, and ’being shown up'. All of those are shown to have a rational base and to be the product of complex negotiations. Teacher realities at the school are also categorized into three major, and highly contrasting areas of activity, namely ’surviving’, ’being professionals’, and ’being persons’. Much of the teacher’s classroom activity appears to have ’survival’ as the major goal, often under cover of ’teaching’. In other instances, for example when writing school reports, teachers act as 'professionals’, articulating ideal models of pupils and their expertise as teachers. In the staffroom, however, school matters are often viewed through a different perspective, not out of character with that employed in the private, as opposed to public sphere of life. As with the pupils, laughter is a key element. The thesis points to the effects of institutional forms upon the individual and upon relationships, over and above the considerable influence of external forces.

description: Motivated by the aero-acoustic feedback loop phenomenon in high speed free jets and impinging jets, a thorough examination of a POD (Proper Orthogonal Decomposition)-Galerkin method to determine the average convection velocity of coherent structures in the shear layer is presented in this paper. The technique is shown to be applicable to both time resolved as well as time unresolved data, if the data set meets certain requirements. Using a detailed sensitivity analysis on a synthetic data set, a quantitative estimate on the required time resolution for the technique has been found, which can be useful for both experimental, as well as numerical studies investigating the aero-acoustic feedback loop in high speed flows. Moreover, some innovative ways to apply the technique are also demonstrated using a simulated data set, showing the effectiveness of the technique to any general problem in supersonic jets, heat transfer, combustion or other areas in fluid mechanics, where an advection process can be identified.
Reducing bird-window collisions at a botanical garden : The effect of bird-friendly artwork and dirty windows
Creators: name: Crews, Christie
Publisher: name: The University of British Columbia
Year: 2022

description: With up to 42 million dying each year due to window strikes, evaluating the effectiveness of mitigation strategies is a must to protect vulnerable bird species. One of the most effective strategies is the application of decals to the outside surface of a window. Commercial products, such as Feather Friendly® bird deterrent film, use a grid pattern of small dots that helps reduce visual obstruction for humans. However, bird-friendly artwork has been suggested as a strategy that combines effectiveness and aesthetic appeal, but has not been critically evaluated. Dirty windows too, are suggested as being effective, but little research exists to support these claims. This study performed bird collision monitoring at the UBC Botanical Garden before and after the application of bird-friendly artwork to the Pavilion, and during a time where dirt was allowed to accumulate on the windows at the Garden Centre. Monitoring was performed 4 times a week for 8 weeks during February and March. Building facades were searched for collision evidence, such as carcasses, feather piles, and feather smears. The reduction in collisions was dramatic; collisions decreased from 11 to 0 at the Pavilion, and from 84 to 3 at the Garden Centre. The results of this study support the use of bird-friendly artwork and dirty windows as management strategies for bird collisions, but also support student engagement in identifying collision hotspots and informing mitigation. Continued monitoring of the garden is suggested. Future research is needed to quantify the level of dirt on a window and how that effects collision risk, as well as research into public perception of dirty windows. Overall, the results of this study are promising for the future of birds at the UBC Botanical Garden.

Anomalous diffusion, Localization, Aging and Sub-aging effects in trap models at very low temperature

description: We study in details the dynamics of the one dimensional symmetric trap model, via a real-space renormalization procedure which becomes exact in the limit of zero temperature. In this limit, the diffusion front in each sample consists in two delta peaks, which are completely out of equilibrium with each other. The statistics of the positions and weights of these delta peaks over the samples allows to obtain explicit results for all observables in the limit $T \to 0$. We first compute disorder averages of one-time observables, such as the diffusion front, the thermal width, the localization parameters, the two-particle correlation function, and the generating function of thermal cumulants of the position. We then study aging and sub-aging effects : our approach reproduces very simply the two different aging exponents and yields explicit forms for scaling functions of the various two-time correlations. We also extend the RSRG method to include systematic corrections to the previous zero temperature procedure via a series expansion in $T$. We then consider the generalized trap model with parameter $α\in [0,1]$ and obtain that the large scale effective model at low temperature does not depend on $α$ in any dimension, so that the only observables sensitive to $α$ are those that measure the `local persistence', such as the probability to remain exactly in the same trap during a time interval. Finally, we extend our approach at a scaling level for the trap model in $d=2$ and obtain the two relevant time scales for aging properties.

Coulomb Interactions via Local Dynamics: A Molecular--Dynamics Algorithm

Year: 2004
Subjects: subject: Statistical Mechanics (cond-mat.stat-mech)

description: We derive and describe in detail a recently proposed method for obtaining Coulomb interactions as the potential of mean force between charges which are dynamically coupled to a local electromagnetic field. We focus on the Molecular Dynamics version of the method and show that it is intimately related to the Car--Parrinello approach, while being equivalent to solving Maxwell's equations with freely adjustable speed of light. Unphysical self--energies arise as a result of the lattice interpolation of charges, and are corrected by a subtraction scheme based on the exact lattice Green's function. The method can be straightforwardly parallelized using standard domain decomposition. Some preliminary benchmark results are presented.

Do Metal-Rich Stars Make Metal-Rich Planets? New Insights on Giant Planet Formation from Host Star Abundances

description: The relationship between the compositions of giant planets and their host stars is of fundamental interest in understanding planet formation. The solar system giant planets are enhanced above solar composition in metals, both in their visible atmospheres and bulk compositions. A key question is whether the metal enrichment of giant exoplanets is correlated with that of their host stars. Thorngren et al. (2016) showed that in cool (Teq < 1000 K) giant exoplanets, the total heavy-element mass increases with total Mp and the heavy element enrichment relative to the parent star decreases with total Mp. In their work, the host star metallicity was derived from literature [Fe/H] measurements. Here we conduct a more detailed and uniform study to determine whether different host star metals (C, O, Mg, Si, Fe, and Ni) correlate with the bulk metallicity of their planets, using correlation tests and Bayesian linear fits. We present new host star abundances of 19 cool giant planet systems, and combine these with existing host star data for a total of 22 cool giant planet systems (24 planets). Surprisingly, we find no clear correlation between stellar metallicity and planetary residual metallicity (the relative amount of metal versus that expected from the planet mass alone), which is in conflict with common predictions from formation models. We also find a potential correlation between residual planet metals and stellar volatile-to-refractory element ratios. These results provide intriguing new relationships between giant planet and host star compositions for future modeling studies of planet formation.

Measuring 2beta+gamma with color-allowed B0 -> D+- Ks pi-+ decays

Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: We present a method to measure the weak phase 2beta+gamma in the three-body decay B0 -> D+- Ks pi-+. These decays are mediated by interfering amplitudes which are color-allowed and hence relatively large. In addition, the three-body decay helps to resolve discrete ambiguities present in measurements of the weak phase. The experimental implications are discussed, and the sensitivity of the method is evaluated using a simulation.

description: We present results from a deep (174 ks) Chandra observation of the FR-II radio galaxy 3C 220.1, the central brightest cluster galaxy (BCG) of a $kT \sim$ 4 keV cluster at $z=0.61$. The temperature of the hot cluster medium drops from $\sim5.9$ keV to $\sim3.9$ keV at $\sim$ 35 kpc radius, while the temperature at smaller radii may be substantially lower. The central active galactic nucleus (AGN) outshines the whole cluster in X-rays, with a bolometric luminosity of $2.0\times10^{46}$ erg s$^{-1}$ ($\sim10$% of the Eddington rate). The system shows a pair of potential X-ray cavities $\sim35$ kpc east and west of the nucleus. The cavity power is estimated within the range of $1.0\times10^{44}$ erg s$^{-1}$ and $1.7\times10^{45}$ erg s$^{-1}$, from different methods. The X-ray enhancements in the radio lobes could be due to inverse Compton emission, with a total 2-10 keV luminosity of $\sim8.0\times10^{42}$ erg s$^{-1}$. We compare 3C 220.1 with other cluster BCGs, including Cygnus A, as there are few BCGs in rich clusters hosting an FR-II galaxy. We also summarize the jet power of FR-II galaxies from different methods. The comparison suggests that the cavity power of FR-II galaxies likely under-estimates the jet power. The properties of 3C 220.1 suggest that it is at the transition stage from quasar-mode feedback to radio-mode feedback.

description: The Mott insulator state created by loading an atomic Bose-Einstein condensate (BEC) into an optical lattice may be used as a means to prepare a register of atomic qubits in a quantum computer. Such architecture requires a lattice commensurately filled with atoms, which corresponds to the insulator state only in the limit of zero inter-well tunneling. We show that a lattice with spatial inhomogeneity created by a quadratic magnetic trapping potential can be used to isolate a subspace in the center which is impervious to hole-hoping. Components of the wavefunction with more than one atom in any well can be projected out by selective measurement on a molecular photo-associative transition. Maintaining the molecular coupling induces a quantum Zeno effect that can sustain a commensurately filled register for the duration of a quantum computation.
