description: Star-forming regions show a rich and varied chemistry, including the presence of complex organic molecules - both in the cold gas distributed on large scales, and in the hot regions close to young stars where protoplanetary disks arise. Recent advances in observational techniques have opened new possibilities for studying this chemistry. In particular, the Atacama Large Millimeter/submillimeter Array (ALMA) has made it possible to study astrochemistry down to Solar System size scales, while also revealing molecules of increasing variety and complexity. In this review, we discuss recent observations of the chemistry of star-forming environments, with a particular focus on complex organic molecules, taking context from the laboratory experiments and chemical models that they have stimulated. The key takeaway points are: The physical evolution of individual sources plays a crucial role in their inferred chemical signatures, and remains an important area for observations and models to elucidate. Comparisons of the abundances measured toward different star-forming environments (high-mass versus low-mass, Galactic center versus Galactic disk) reveal a remarkable similarity, an indication that the underlying chemistry is relatively independent of variations in their physical conditions. Studies of molecular isotopologs in star-forming regions provide a link with measurements in our own Solar System, and thus may shed light on the chemical similarities and differences expected in other planetary systems.

description: Drones or Unmanned Aerial Vehicles (UAVs) have become a reliable and efficient tool for road traffic monitoring. Compared to loop detectors and bluetooth receivers (with high capital and operational expenditure), drones are a low-cost alternative that offers great flexibility and high quality data. In this work, we derive optimized tour plans that a fleet of drones can follow for rapid traffic monitoring across particular regions of transportation network. To derive these tours, we first identify monitoring locations over which drones should fly through and then compute minimum travel-time tours based on realistic resource constraints. Evaluation results are presented over a real road network topology to demonstrate the applicability of the proposed approach.

description: Welfare economics is often employed to measure the impact of economic policies or externalities. When demand is characterized by discrete choices, static models of consumer demand are employed for this type of analysis because of the difficulty in estimating dynamic discrete choice models. In this paper we provide a tractable approach to estimating dynamic discrete choice models of the Generalized Extreme Value (GEV) family that addresses many of the problems identified in the literature and provides a rich set of parameters describing dynamic choice. We apply this model to the case of recreational fishing site choice, comparing dynamic to static versions. In natural resource damage assessment cases, static discrete choice models of recreational site choice are often employed to calculate welfare measures, which will be biased if the underlying preferences are actually dynamic in nature. In our empirical case study we find that the dynamic model provides a richer behavioral model of site choice, and reflects the actual choices very well. We also find significant differences between static and dynamic welfare measures. However, we find that the dynamic model raises several concerns about the specification of the policy impact and the subsequent welfare measurement that are not raised in static cases.

description: Achieving oral communication has become the focus and ultimate goal of the second language learning and teaching process. However, the students do not have enough opportunities to interact in the classroom which can greatly help them develop their speaking skills. In this article, I will try to give some suggestions for students. In order to carry out this project, the qualitative methodology will be used to gather data through classroom observations and the use of oral activities such as simulations, jigsaw and story completion activities. The findings of this research should provide valuable information regarding the effect of using oral activities that involve interaction to develop student’s speaking skills.

description: Few studies have reported the survival outcomes of myeloid leukemia associated with Down syndrome (DS) in resource-limited countries. This study aimed to compare characteristics and survival outcomes of children with acute myeloid leukemia (AML) between those with and without DS in Thailand. The medical records of AML patients aged 0-15 years treated in a major tertiary center in Southern Thailand between October 1978 and December 2019 were reviewed retrospectively. The overall (OS) and event-free survivals (EFS) rates were calculated using the Kaplan-Meier method. A total of 362 AML patients were included, of which 41 (11.3%) had DS. The mean age at diagnosis of the DS patients was 2.5 ± 1.9 years and most of them (90.2%) were under the age of five. The DS patients had lower initial white blood cell counts and peripheral blasts compared to the non-DS patients. The AML-M7 subtype was more common in the DS than in the non-DS patients (80.5% vs. 9.1%, p < 0.01, respectively). The 5-year OS and EFS rates of the DS patients were lower compared to the non-DS patients (12.9% vs. 20.5%, p = 0.05 and 13.7% vs. 18.4%, p = 0.03, respectively). DS patients had a significantly higher rate of early and treatment-related deaths compared to non-DS patients (30.3% vs. 13.5%, p < 0.01 and 39.4% vs. 19.5%, p = 0.02, respectively). Over the study period, there were a decrease in early death rate and an increase in survival rates of DS patients, which suggests that chemotherapy regimens and supportive care have improved over time.

description: We present 39 nights of optical photometry, 34 nights of infrared photometry, and 4 nights of optical spectroscopy of the Type Ia SN 1999ac. This supernova was discovered two weeks before maximum light, and observations were begun shortly thereafter. At early times its spectra resembled the unusual SN 1999aa and were characterized by very high velocities in the Ca II H and K lines, but very low velocities in the Si II 6355 A line. The optical photometry showed a slow rise to peak brightness but, quite peculiarly, was followed by a more rapid decline from maximum. Thus, the B- and V-band light curves cannot be characterized by a single stretch factor. We argue that the best measure of the nature of this object is not the decline rate parameter Delta m_15 (B). The B-V colors were unusual from 30 to 90 days after maximum light in that they evolved to bluer values at a much slower rate than normal Type Ia supernovae. The spectra and bolometric light curve indicate that this event was similar to the spectroscopically peculiar slow decliner SN 1999aa.

description: This study examines the economic, social and environmental effects of alternative agricultural methods, traded through fair trade mechanisms, on producers in northern Thailand. These effects are compared with those of conventional agriculture and mixed agriculture (where alternative agriculture and conventional agriculture are practised on the same farm). The chosen research projects and areas in Chiang Mai province, Thailand were the government alternative agriculture project at Village Three in Pong Yang, and the nongovernmental organisations alternative agriculture project at San Pay Yang and the neighbouring San Lueng. The government and non-governmental organisations involved in the extension and marketing of alternative agriculture are outlined and associated labelling and certification issues are addressed. Economic comparisons found that alternative agriculture is a viable economic alternative to conventional agriculture and mixed agriculture when non-farm income and home consumption are included. However, the larger average size of alternative agriculture farms and the external funding of the organisations involved with alternative agriculture, must also be considered. Social comparisons indicated that alternative agriculture results in educational and health benefits when compared to conventional agriculture. Environmental comparisons showed that on average alternative agriculture has the highest level of crop and livestock integration, the lowest number of artificial agricultural inputs used, and the highest number of alternatives to artificial inputs applied.
Tidal disruption versus planetesimal collisions as possible origins for the dispersing dust cloud around Fomalhaut

description: Recent analysis suggests that the faint optical point source observed around Fomalhaut from 2004-2014 (Fomalhaut b) is gradually fading and expanding, supporting the case that it may be a dispersing dust cloud resulting from the sudden disruption of a planetesimal. These types of disruptions may arise from catastrophic collisions of planetesimals, which are perturbed from their original orbits in the Fomalhaut dust ring by nearby giant planets. However, disruptions can also occur when the planetesimals pass within the tidal disruption field of the planet(s) that perturbed them in the first place, similar to the Shoemaker-Levy event observed in the Solar System. Given that a gravitationally focusing giant planet has a much larger interaction cross-section than a planetesimal, tidal disruption events can match or outnumber planetesimal collision events in realistic regions of parameter space. Intriguingly, the Fomalhaut dust cloud offers an opportunity to directly distinguish between these scenarios. A tidal disruption scenario leads to a very specific prediction of ephemerides for the planet causing the event. At a most probable mass of 66 Mearth, a semi-major axis of 117 AU, and a system age of 400-500 Myr, this planet would be readily detectable with the James Webb Space Telescope. The presence or absence of this planet at the specific, predicted position is therefore a distinctive indicator of whether the dispersing cloud originated from a collision of two planetesimals or from the disruption of a planetesimal in the tidal field of a giant planet.

description: A taxonomy for describing property rights to natural resources is described and applied in a Zimbabwean case study. The taxonomy allows: tenures to be systematically compared and contrasted; incentives for natural resource management to be identified; and the evolution of tenure to natural resources to be assessed. In the case study, we find: key differences between tenure types, all termed "communal"; a wide range of tenure arrangements that transcend concepts of "tree" and "land tenure"; information suggesting that the promotion of tree planting may work on some tenure types, but is likely to fail on others; and that the evolution of indigenous tenure to natural resources seems to have been somewhat immune from external changes in institutional systems. Prospects for further theoretical and empirical advances are discussed within the context of the property rights framework presented.

description: Cygnus X-3 is a strong X-ray source (L_X about 10^38 erg/s) which is thought to consist of a compact object, accreting matter from a helium star. We find analytically that the estimated ranges of mass-loss rate and orbital-period derivative for Cyg X-3 are consistent with two models: i) the system is detached and the mass loss from the system comes from the stellar wind of a massive helium star, of which only a fraction that allows for the observed X-ray luminosity is accreted, or ii) the system is semidetached and a Roche-lobe-overflowing low- or moderate-mass helium donor transfers mass to the compact object, followed by ejection of its excess over the Eddington rate from the system. These analytical results appear to be consistent with evolutionary calculations. By means of population synthesis we find that currently in the Galaxy there may exist ~1 X-ray binary with a black hole that accretes from a >~ 7 MSun Wolf-Rayet star and ~1 X-ray binary in which a neutron star accretes matter from a Roche-lobe-overflowing helium star with mass

description: This study evaluates the impacts of the Uruguay Round Agreement (URA) on Canadian agriculture in a single-country general equilibrium framework. For this purpose a computable general equilibrium model of the Canadian economy that involves six agricultural and two non-agricultural sectors was constructed and calibrated on 1991 data. To assess whether Canadian agriculture benefits from the URA, two sets of anticipated changes in world prices, taken from studies of the global effects of the URA, were introduced into the model exogenously. The simulation experiments show that the minimum increases in world prices from global studies are too small to offset the negative effects on agriculture of the reductions in tariffs, export subsidies and domestic support. However, if world prices were to change by the maximum level of global projections, Canadian agricultural producers gain from the URA. The sectors that benefit the most are wheat, other grains, and processed foods, for which production and exports increase appreciably. Imports of milk and poultry products increase substantially and livestock sector imports also increase. Labour and capital demand increase in agriculture, particularly in the wheat and other grains sectors. The highest increase in factor returns in agriculture is for agricultural land. Since the export prices applied above are exogenously determined, a third experiment is conducted to determine the extent of the world price changes for agricultural exports that would offset the negative effects on sectoral domestic production of the URA policy commitments. This would require world prices that are about eleven per cent higher than in the base period for wheat and about ten per cent higher for other grains. The greatest increase in prices--by nearly thirteen per cent--would be required for the milk and poultry sector. More modest changes in world prices for the other agricultural sectors are needed to offset the impacts of the reductions in sectoral support necessitated by the URA. Most of these price changes lie within the ranges of world price projections from studies of the global effects of the URA.

description: Our aim was to identify national consensus criteria for the management of children with chemotherapy-induced febrile neutropenia (FN), for evidence-based step-down treatment approaches for patients classified at low risk of severe infection. In 2018, a five-section, 38-item survey was e-mailed to all pediatric hematology and oncology units in France (n = 30). The five sections contained statements on possible consensus criteria for the (i) definition of FN, (ii) initial management of children with FN, (iii) conditions required for initiating step-down therapy in low-risk patients, (iv) management strategy for low-risk patients, and (v) antibiotic treatment on discharge. Consensus was defined by respondents’ combined answers (somewhat agree and strongly agree) at 75% or more. Sixty-five physicians (participation rate: 58%), all specialists in pediatric onco-hematology, from 18 centers completed the questionnaire. A consensus was reached on 22 of the 38 statements, including the definition of FN, the criteria for step-down therapy in low-risk children, and the initial care of these patients. There was no consensus on the type and duration of antibiotic therapy on discharge. In conclusion, a consensus has been reached on the criteria for initiating evidence-based step-down treatment of children with FN and a low risk of severe infection but not for the step-down antimicrobial regimen.

description: We obtained spectra, covering the CaII H and K region, for 49 exoplanet host (EH) stars, observable from the southern hemisphere. We measured the chromospheric activity index, Rhk. We compiled previously published values of this index for the observed objects as well as the remaining EH stars in an effort to better smooth temporal variations and derive a more representative value of the average chromospheric activity for each object. We used the average index to obtain ages for the group of EH stars. In addition we applied other methods, such as: Isochrone, lithium abundance, metallicity and transverse velocity dispersions, to compare with the chromospheric results. The kinematic method is a less reliable age estimator because EH stars lie red-ward of Parenago's discontinuity in the transverse velocity dispersion vs dereddened B-V diagram. The chromospheric and isochrone techniques give median ages of 5.2 and 7.4 Gyr, respectively, with a dispersion of 4 Gyr. The median age of F and G EH stars derived by the isochrone technique is 1--2 Gyr older than that of identical spectral type nearby stars not known to be associated with planets. However, the dispersion in both cases is large, about 2--4 Gyr. We searched for correlations between the chromospheric and isochrone ages and Lir/L* (the excess over the stellar luminosity) and the metallicity of the EH stars. No clear tendency is found in the first case, whereas the metallicy dispersion seems to slightly increase with age.

description: Real-time online interaction is the norm today. Tabletops and other dedicated interactive surface devices with direct input and tangible interaction can enhance remote collaboration, and open up new interaction scenarios based on mixed physical/virtual components. However, they are only available to a small subset of users, as they usually require identical bespoke hardware for every participant, are complex to setup, and need custom scenario-specific applications.
We present SurfaceCast, a software toolkit designed to merge multiple distributed, heterogeneous end-user devices into a single, shared mixed-reality surface. Supported devices include regular desktop and laptop computers, tablets, and mixed-reality headsets, as well as projector-camera setups and dedicated interactive tabletop systems. This device-agnostic approach provides a fundamental building block for exploration of a far wider range of usage scenarios than previously feasible, including future clients using our provided API.
In this paper, we discuss the software architecture of SurfaceCast, present a formative user study and a quantitative performance analysis of our framework, and introduce five example application scenarios which we enhance through the multi-user and multi-device features of the framework. Our results show that the hardware- and content-agnostic architecture of SurfaceCast can run on a wide variety of devices with sufficient performance and fidelity for real-time interaction.

description: The multiple ferroelectric polarization tuned by external electric field could be used to simulate the biological synaptic weight. Ferroelectric synaptic devices have two advantages compared with other reported ones: One is the intrinsic switching of ferroelectric domains without invoking of defect migration as in resistive oxides contributes reliable performance in these ferroelectric synapses. Another tremendous advantage is the extremely low energy consumption because the ferroelectric polarization is manipulated by electric field which eliminate the Joule heating by current as in magnetic and phase change memory. Ferroelectric synapses are potential for the construction of low-energy and effective brain-like intelligent networks. Here we summarize recent pioneering work of ferroelectric synapses involving the structure of ferroelectric tunnel junctions (FTJs), ferroelectric diodes (FDs) and ferroelectric field effect transistors (FeFETs), respectively, and shed light on future work needed to accelerate their application for efficient neural network.

We measure the inclusive B cross-section to be sigma(Y(5S)-->BB(X))=(0.176+-0.030+-0.016) nb and make the first measurements of the production rates of sigma(Y(5S)-->B*B*)=(0.131+-0.025+-0.014) nb and sigma(Y(5S)-->BB*)=(0.043+-0.016+-0.006) nb, respectively. We set 90% confidence level limits of sigma(Y(5S)-->B B-bar)<0.038 nb, sigma(Y(5S)-->B(*)B(*)(pi))<0.055 nb and sigma(Y(5S)-->BBpipi)<0.024 nb. We also extract the most precise value of the B_s* mass to date, M(B_s*)=(5411.7+-1.6+-0.6) MeV/c^2.

description: The internal structure and strength of small asteroids and large meteoroids is poorly known. Observation of bright fireballs in the Earth's atmosphere can prospect meteoroid structure by studying meteoroid fragmentation during the flight. Earlier evaluations showed that meteoroid strength is significantly lower than that of the recovered meteorites. We present detailed study of atmospheric fragmentation of seven meteorite falls, all ordinary chondrites, and 14 other fireballs, where meteorite fall was predicted but the meteorites, probably also ordinary chondrites, were not recovered. All observations were made by the autonomous observatories of the European Fireball Network and include detailed radiometric light curves. A model, called the semi-empirical fragmentation model, was developed to fit the light curves and decelerations. Videos showing individual fragments were available in some cases. The results demonstrated that meteoroids do not fragment randomly but in two distinct phases. The first phase typically corresponds to low strengths of 0.04 - 0.12 MPa. In 2/3 of cases, the first phase was catastrophic or nearly catastrophic with at least 40% of mass lost. The second phase corresponds to 0.9 - 5 MPa for confirmed meteorite falls and to somewhat lower strengths, from about 0.5 MPa for smaller meteoroids. All these strengths are lower than tensile strengths of ordinary chondritic meteorites cited in the literature, 20 - 40 MPa. We interpret the second phase as being due by cracks in meteoroids and the first phase as separation of weakly cemented fragments, which reaccumulated at surfaces of asteroids after asteroid collisions.

In this trial, children with LR-FN with an afebrile period of at least 24 h, sterile blood culture, and negative/normalized PCT were randomized at 72 h of starting antibiotics into two groups: intervention arm and standard arm. The antibiotics were stopped in the intervention arm regardless of absolute neutrophil count (ANC), while in the standard arm, antibiotics were continued for at least 7 days or until recovery of ANC (>500/mm3). The primary objective was to determine the treatment failure rates, and the secondary objective was to compare the duration of antibiotics and all-cause mortality between the two arms. A total of 46 children with LR-FN were randomized to either the intervention arm (n = 23) or the standard arm (n = 23). Treatment failure was observed in 2/23 (8.7%) of patients in the intervention arm compared to 1/23 (4.3%) in the standard arm [RR: 2 (95% CI: 0.19–20.6); p = 0.55]. The median duration of antibiotics in the intervention arm and standard arm were 3 days vs 7 days (P= <0.001). There was no mortality in this study. PCT-guided early discontinuation of empirical antibiotics in LR-FN is feasible. There was no significant difference observed in treatment failure between the early discontinuation of antibiotics vs standard therapy. The total duration of antibiotic exposure was significantly lesser in the discontinuation arm. Further, larger multicenter studies are needed to confirm the finding of this study.
Debating sacred space in the city : religion and taxation in interwar Victoria and Vancouver
Creators: name: Cunningham, Kara Lynn

description: Scholars have sorely neglected the subject of religion in British Columbia during the interwar years. This thesis will address this gap through a study of the relationship between Protestantism and society in the province's major urban centers, Vancouver and Victoria. I will approach the issue through a new window into the role of churches in British Columbia - the church taxation debates of the 1920's. This work begins with a review of the literature that sets the historical context of the church tax issue and reveals gaps in our knowledge of the role of religion in British Columbia. Primary source material is derived largely from newspapers, magazines, and archival material including private correspondences, City Council documents, pamphlets, and booklets. The church taxation issue illustrates the agenda of British Columbia's urban churches in a rapidly changing and secularizing society. In order to remain relevant, they were forced to consider their purpose and persuade society to agree. Exemptionists employed different strategies to convince the public of their indispensability. In Victoria, churches clung to tradition, while in Vancouver churches responded by redefining the relationship between church and state. Victoria's churches wanted the role of churches to remain unchanged while Vancouver churches sought to harmonize the churches' agenda with that of the state. In both cities, the exemptionists won their cases. However, their victories did not permanently define or secure the future role of churches.

description: GRB 200219A is a short gamma-ray burst (GRB) with an extended emission (EE) lasting $\sim 90$s. By analyzing data observed with the {\em Swift}/BAT and {\em Fermi}/GBM, we find that a cutoff power-law model can adequately fit the spectra of the initial short pulse with $\rm E_{p}=1387^{+232}_{-134}$ keV. More interestingly, together with the EE component and early X-ray data, it exhibits plateau emission smoothly connected with a $\sim t^{-1}$ segment and followed by an extremely steep decay. The short GRB composed of those three segments is unique in the {\em Swift} era and is very difficult to explain with the standard internal/external shock model of a black hole central engine, but could be consistent with the prediction of a magnetar central engine from the merger of an NS binary. We suggest that the plateau emission followed by a $\sim t^{-1}$ decay phase is powered by the spin-down of a millisecond magnetar, which loses its rotation energy via GW quadrupole radiation. Then, the abrupt drop decay is caused by the magnetar collapsing into a black hole before switching to EM-dominated emission. This is the first short GRB for which the X-ray emission has such an intriguing feature powered by a magnetar via GW-dominated radiation. If this is the case, one can estimate the physical parameters of a magnetar, the GW signal powered by a magnetar and the merger-nova emission are also discussed.

description: We study a global game in which actions are strategic complements over some region and strategic substitutes over another region. An agent's payoff depends on a market fundamental and the actions of other agents. If the degree of congestion is sufficiently large, agents' strategies are non-monotonic in their signal about the market fundamental. In this case, a signal that makes them believe that the market fundamental is more favorable for an action may make them less likely to take the action, because of the risk of overcrowding.

Double neutron/proton ratio of nucleon emissions in isotopic reaction systems as a robust probe of nuclear symmetry energy

description: The double neutron/proton ratio of nucleon emissions taken from two reaction systems using four isotopes of the same element, namely, the neutron/proton ratio in the neutron-rich system over that in the more symmetric system, has the advantage of reducing systematically the influence of the Coulomb force and the normally poor efficiencies of detecting low energy neutrons. The double ratio thus suffers less systematic errors. Within the IBUU04 transport model the double neutron/proton ratio is shown to have about the same sensitivity to the density dependence of nuclear symmetry energy as the single neutron/proton ratio in the neutron-rich system involved. The double neutron/proton ratio is therefore more useful for further constraining the symmetry energy of neutron-rich matter.

description: This paper describes an engine to optimize web publisher revenues from second-price auctions. These auctions are widely used to sell online ad spaces in a mechanism called real-time bidding (RTB). Optimization within these auctions is crucial for web publishers, because setting appropriate reserve prices can significantly increase revenue. We consider a practical real-world setting where the only available information before an auction occurs consists of a user identifier and an ad placement identifier. The real-world challenges we had to tackle consist mainly of tracking the dependencies on both the user and placement in an highly non-stationary environment and of dealing with censored bid observations. These challenges led us to make the following design choices: (i) we adopted a relatively simple non-parametric regression model of auction revenue based on an incremental time-weighted matrix factorization which implicitly builds adaptive users' and placements' profiles; (ii) we jointly used a non-parametric model to estimate the first and second bids' distribution when they are censored, based on an on-line extension of the Aalen's Additive model. Our engine is a component of a deployed system handling hundreds of web publishers across the world, serving billions of ads a day to hundreds of millions of visitors. The engine is able to predict, for each auction, an optimal reserve price in approximately one millisecond and yields a significant revenue increase for the web publishers.

description: In this paper different models of vertical relationships between manufacturers and retailers in the supermarket industry are compared. Demand estimates are used to compute price-cost margins for retailers and manufacturers under different supply models when wholesale prices are not observed. The purpose is to identify which set of margins is compatible with the margins obtained from estimates of cost, and to select the model most consistent with the data among non-nested competing models. The models considered are : (1) a simple linear pricing model; (2) a vertically integrated model; and (3) a variety of alternative (strategic) supply scenarios that allow for collusion, non-linear pricing and strategic behavior with respect to private label products. Using data on yogurt sold in several stores in a large urban area of the United States the results imply that wholesale prices are close to marginal cost and that retailers have pricing power in the vertical chain. This is consistent with non-linear pricing by the manufacturers, or high bargaining power of the retailers.
Minimum search space and efficient methods for structural cluster optimization

description: A novel unification for the problem of search of optimal clusters under a well pair potential function is presented. My formulation introduces appropriate sets and lattices from where efficient methods can address this problem. First, as results of my propositions a discrete set is depicted such that the solution of a continuous and discrete search of an optimal cluster is the same. Then, this discrete set is approximated by a special lattice IF. IF stands for a lattice that combines lattices IC and FC together. In fact, two lattices IF with 9483 and 1739 particles are obtained with the property that they include all putative optimal clusters from 2 trough 1000 particles, even the difficult optimal Lennard-Jones clusters, C*38, C*98, and the Ino's decahedrons. C*98 is the only cluster where its initial configuration has a different geometry than the putative optimal cluster in term of the adjacency matrix stated by Hoare. My paper is not a benchmark, I develop a theory and a numerical experiment for the state of the art of the optimal Lennard-Jones clusters and even I found new optimal Lennard-Jones clusters with a greedy search method called Modified Peeling Method. The paper includes all the necessary data to allow the researchers reproduce the state of the art of the optimal Lennard-Jones clusters at April 8, 2005. This novel formulation unifies the geometrical motifs of the optimal Lennard-Jones clusters and gives new insight towards the understanding of the complexity of the NP problems.
