description: We report the results of two XMM-Newton observations of the ultra-compact low-mass X-ray binary 4U1850-087 located in the galactic globular cluster NGC6712. A broad emission feature at 0.7keV was detected in an earlier ASCA observation and explained as the result of an unusual Ne/O abundance ratio in the absorbing material local to the source. We find no evidence for this feature and derive Ne/O ratios in the range 0.14-0.21, consistent with that of the interstellar medium. During the second observation, when the source was 10% more luminous, there is some evidence for a slightly higher Ne/O ratio and additional absorption. Changes in the Ne/O abundance ratio have been detected from another ultra-compact binary, 4U1543-624. We propose that these changes result from an X-ray induced wind which is evaporated from an O and Ne rich degenerate donor. As the source X-ray intensity increases so does the amount of evaporation and hence the column densities and abundance ratio of Ne and O.

A note on Bödewadt-Hartmann layers
Creators: name: Davidson, Peter A.

Year: 2020
Subjects: subject: Fluid Dynamics (physics.flu-dyn)
subject: FOS: Physical sciences

description: This paper addresses the problem of axisymetric rotating flows bounded by a fixed horizontal plate and subject to a permanent, uniform, vertical magnetic field (the so-called Bödewadt-Hartmann problem). The aim is to find out which one of the Coriolis or the Lorentz force dominates the dynamics (and hence the boundary layer thickness) when their ratio, represented by the Elsasser number $A$, varies. After a short review of existing linear solutions of the semi infinite Ekman-Hartmann problem, weakly non-linear analytical solutions as well as fully non-linear numerical solutions are given. The case of a rotating vortex in a finite depth fluid layer is then studied, first when the flow is steady under a forced rotation and second for spin-down from some initial state. The angular velocity in the first case and decay time in the second are obtained analytically as a function of $A$ using the weakly non linear results of the semi-infinite Bödewadt-Hartmann problem.

description: Numerical Simulation is an essential part of the design and optimisation of astronomical adaptive optics systems. Simulations of adaptive optics are computationally expensive and the problem scales rapidly with telescope aperture size, as the required spatial order of the correcting system increases. Practical realistic simulations of AO systems for extremely large telescopes are beyond the capabilities of all but the largest of modern parallel supercomputers. Here we describe a more cost effective approach through the use of hardware acceleration using field programmable gate arrays. By transferring key parts of the simulation into programmable logic, large increases in computational bandwidth can be expected. We show that the calculation of wavefront sensor image centroids can be accelerated by a factor of four by transferring the algorithm into hardware. Implementing more demanding parts of the adaptive optics simulation in hardware will lead to much greater performance improvements, of up to 1000 times.

description: Engaging students with well-designed multiple-choice questions during class and asking them to discuss their answers with their peers after each student has contemplated the response individually can be an effective evidence-based active-engagement pedagogy in physics courses. Moreover, validated sequences of multiple-choice questions are more likely to help students build a good knowledge structure of physics than individual multiple-choice questions on various topics. Here we discuss a framework to develop robust sequences of multiple-choice questions and then use the framework for the development, validation and implementation of a sequence of multiple-choice questions focusing on helping students learn quantum mechanics via the Stern-Gerlach experiment that takes advantage of the guided inquiry-based learning sequences in an interactive tutorial on the same topic. The extensive research in developing and validating the multiple-choice question sequence strives to make it effective for students with diverse prior preparation in upper-level undergraduate quantum physics courses. We discuss student performance on assessment task focusing on the Stern-Gerlach experiment after traditional lecture-based instruction vs. after engaging with the research-validated multiple-choice question sequence administered as clicker questions in which students had the opportunity to discuss their responses with their peers.

description: This paper first identifies an interesting pattern in farm household livestock production in many developing countries: an inverted-U shape relationship between household livestock production and the levels of economic development (or farm household income). Using backyard hog production as a case study, the paper documents the ways in which trends in market development appear to correspond with observed trends in household hog production. After providing theoretical explanation of linkage between market development and household hog production, the paper econometrically estimates the effects of market development on household hog production. The results indicate that grain and labor market development can explain a significant portion of the rise and fall in China's backyard hog sector over the past two decades.

Subjects: subject: Superconductivity (cond-mat.supr-con)

description: Recently deiscovered superconductivity in YbC$_6$ and CaC$_6$ at temperatures substantially higher than previously known for intercalated graphites, raised several new questions: (1) Is the mechanism considerably different from the previously known intercalated graphites? (2) If superconductivity is conventional, what are the relevant phonons? (3) Given extreme similarity between YbC$_6$ and CaCa$_6$, why their critical temperatures are so different? We address these questions on the basis of first-principles calculations and conclude that coupling with intercalant phonons is likely to be the main force for superconductivity in YbC$_6$ and CaC$_6$, but not in alkaline-intercalated compounds, and explain the difference in $T_c$ by the ``isotope effect'' due to the difference in Yb and Ca atomic masses.

description: Engaging students with well-designed clicker questions is one of the commonly used research-based instructional strategy in physics courses partly because it has a relatively low barrier to implementation. Moreover, validated robust sequences of clicker questions are likely to provide better scaffolding support and guidance to help students build a good knowledge structure of physics than an individual clicker question on a particular topic. Here we discuss the development, validation and in-class implementation of a clicker question sequence (CQS) for helping advanced undergraduate students learn about Larmor precession of spin, which takes advantage of the learning goals and inquiry-based guided learning sequences in a previously validated Quantum Interactive Learning Tutorial (QuILT). The in-class evaluation of the CQS using peer instruction is discussed by comparing upper-level undergraduate student performance after traditional lecture-based instruction and after engaging with the CQS.

Product term mode embedded memory arrays : algorithms and architectures
Creators: name: Lin, Ernest Wei-Lang
Publisher: name: University of British Columbia
Year: 2009

description: Field-Programmable Gate Arrays (FPGAs) are integrated circuits that can be programmed to implement virtually any digital circuit. Due to the ease with which a user can implement a circuit, FPGAs have become a low-cost, fast-turnaround time alternative to more traditional implementation technologies such as mask-programmed gate arrays and application-specific integrated circuits (ASICs). However, one of the major pitfalls of FPGAs is the area and speed penalty inherent in the technology. In order to help "bridge the gap" between FPGAs and ASICs, intelligent computer-aided design (CAD) tools that use the FPGA as efficiently as possible are needed. In this thesis, we focus on mapping logic to the on-chip memory arrays. In particular, our focus is on the architecture of the product-term mode memory arrays, and the CAD algorithms that target those architectures. First, we focus on an intelligent technology mapping algorithm that maps a circuit to product term mode memory arrays. We show that the algorithm can pack 22.8% more logic blocks into product term mode memory arrays over using conventional memory arrays alone. Second, we focus on the architecture of the product term mode memory array itself, and present several architectural enhancements for increasing the efficiency of the memory array in implementing logic.

description: We determine the structural relaxations around paramagnetic impurities (Ti, Cr, Fe) in corundum (alpha-Al2O3), by combining x-ray absorption near edge structure (XANES) experiments and ab initio calculations. The structural relaxations are found to be very local. We then show that XANES is sensitive to small variations in interatomic distances within the coordination shell of the absorbing atom. The experiments were carried out on single crystals of ruby and sapphires. Linear dichroic signals are essential to characterize the geometry of the impurity site. The calculations were performed within a self-consistent ``non muffin-tin'' framework, that uses pseudopotentials, plane-wave basis set, and the continued fraction for the absorption cross section.

description: There have been a number of high profile food safety disputes in trade over the past decade. These include the widely publicized dispute at the World Trade Organization between the U.S. and EU over hormone treated beef. Consumers in some industrialized countries have also expressed concern over the health implications of consuming beef produced with antibiotics and other artificial supplements. Developing countries are affected in a significant way in both how disputes are settled, as well as the balance between risk and safety reflected in how standards are set. This paper examines the impact of drug residue standards on trade in beef and trade affect of setting harmonized international standards. We find that if international standards set by Codex were followed in antibiotics, global trade in beef would rise by over $3.2 billion. Among other developing countries, South African exports would rise by $160 million, Brazil by $200 million, and Argentina's by over $300 million.
Mathematical estimates for the attractor dimension in MHD turbulence

Year: 2020

subject: FOS: Physical sciences

description: The aim of the present work is to derive rigorous estimates for turbulent MHD flow quantities such as the size and anisotropy of the dissipative scales, as well as the transition between 2D and 3D state. To this end, we calculate an upper bound for the attractor dimension of the motion equations, which indicates the number of modes present in the fully developed flow. This method has already been used successfully to derive such estimates for 2D and 3D hydrodynamic turbulence as a function of the $\mathcal L_\infty$ norm of the dissipation, as in \cite{doering95}. We tackle here the problem of a flow periodic in the 3 spatial directions (spatial period $2πL$), to which a permanent magnetic field is applied. In addition, the detailed study of the dissipation operator provides more indications about the structure of the flow. In section 2, we review the tools of the dynamical system theory as well as the results they have led to in the case of 3D hydrodynamic turbulence. Section 3 is devoted to the study of the set of modes which minimises the trace of the operator associated to the total dissipation in MHD turbulence (viscous and Joule). Eventually, the estimates for the attractor dimension and dissipative scales in MHD turbulence under strong magnetic field are derived in section 4 and compared to results obtained from heuristic considerations.

description: We propose a robust scheme involving atoms fixed in an optical cavity to directly implement the universal controlled-unitary gate. The present technique based on adiabatic passage uses novel dark states well suited for the controlled-rotation operation. We show that these dark states allow the robust implementation of a gate that is a generalisation of the controlled-unitary gate to the case where the control qubit can be selected to be an arbitrary state. This gate has potential applications to the rapid implementation of quantum algorithms such as of the projective measurement algorithm. This process is decoherence-free since excited atomic states and cavity modes are not populated during the dynamics.

description: The adoption of intelligent systems with Artificial Neural Networks (ANNs) embedded in hardware for real-time applications currently faces a growing demand in fields like the Internet of Things (IoT) and Machine to Machine (M2M). However, the application of ANNs in this type of system poses a significant challenge due to the high computational power required to process its basic operations. This paper aims to show an implementation strategy of a Multilayer Perceptron (MLP) type neural network, in a microcontroller (a low-cost, low-power platform). A modular matrix-based MLP with the full classification process was implemented, and also the backpropagation training in the microcontroller. The testing and validation were performed through Hardware in the Loop (HIL) of the Mean Squared Error (MSE) of the training process, classification result, and the processing time of each implementation module. The results revealed a linear relationship between the values of the hyperparameters and the processing time required for classification, also the processing time concurs with the required time for many applications on the fields mentioned above. These findings show that this implementation strategy and this platform can be applied successfully on real-time applications that require the capabilities of ANNs.

description: Observational data suggest that a belt of planetesimals is expected close to the snow line in protoplanetary disks. Assuming there is such a belt in TRAPPIST-1 system, we examine possibilities of water delivery to the planets via planetesimals from the belt. The study is accomplished by numerical simulations of dynamical evolution of a hypothetical planetesimal belt. Our results show that the inner part of the belt is dynamically unstable and planetesimals located in this region are quickly scattered away, with many of them entering the region around the planets. The main dynamical mechanism responsible for the instability are close encounters with the outermost planet Trappist-1h. A low-order mean-motion resonance 2:3 with Trappist-1h, located in the same region, also contributes to the objects transport. In our nominal model, the planets have received non-negligible amount of water, with the smallest amount of $15$\% of the current Earth's water amount (EWA) being delivered to the planet 1b, while the planets Trappist-1e and Trappist-1g have received more than $60$\% of the EWA. We have found that while the estimated efficiency of water transport to the planets is robust, the amount of water delivered to each planet may vary significantly depending on the initial masses and orbits of the planets. The estimated dynamical "half-lives" have shown that the impactors' source region should be emptied in less then 1~Myr. Therefore, the obtained results suggest that transport of planetesimals through the system preferably occurs during an early phase of the planetary system evolution.

description: It has been argued that the traditional regulatory approach of the Endangered Species Act, based on land-use restrictions, has failed to protect endangered species on private land. In response, there has been a call for the use of incentives to complement this regulatory approach. This paper examines the potential of incentives programs to elicit conservation-oriented management choices from landowners. Data obtained from a survey of non-industrial private forest owners in Oregon and Washington is used to examine the effectiveness of various incentives. The results indicate that incentives, in particular compensation and assurances, can be effective in increasing the conservation effort provided by landowners. The results also suggest that conservation policy for private lands could be improved by relying on a combination of incentives, including financial incentives and assurances, rather than exclusively on the threat of regulation.

description: The European Union (EU) ban on the production and importation of meat derived from animals treated with growth-promoting hormones has spurred considerable debate. However, relatively little research has considered how EU consumers have been affected or how they feel about the ban. The purpose of this research is to determine beef product preferences of EU consumers and to elicit how much, if anything, these consumers are willing to pay for their preferred attributes. More specifically, this study uses a non-hypothetical choice experiment to evaluate how EU consumers value beef steaks from animals produced using growth hormones, fed genetically modified feeds, and from U.S. origin relative to their typical, domestically produced steaks. Results reveal that consumers in London, England; Frankfurt, Germany; and Paris, France are on average willing to pay a premium ($8.75/lb, $3.25/lb, and $0.98/lb, respectively) for a "USDA Choice No Hormones or GMOs" steak as opposed to their "Domestic Typical" steak. Additionally, these consumers indicated a willingness to pay a premium for both U.S. produced hormone-free beef ($0.86/lb in London, $1.93/lb in Frankfurt, and $0.30/lb in Paris) and for U.S. produced beef free of genetically modified organisms ($8.88/lb in London, $2.55/ lb in Frankfurt, and $2.79/lb in Paris) relative to USDA Choice beef.

description: This investigation of the potential savings to the State of North Dakota because of reduced office space and labor costs and alternatively, the potential benefits to rural communities of increasing employment by adding some state agency jobs was stimulated by Senate Concurrent Resolution No. 4006, which directed the Legislative Council to study state agency office space needs to determine the feasibility and desirability of transferring state agencies or state employees to rural areas. The objective of this analysis was two-fold; (1) determine the cost difference of operating offices in Bismarck versus rural communities and (2) determine the local/regional economic impacts of the potential jobs. The results indicated that development of satellite data processing offices may be a way for the State of North Dakota to save resources by decreasing operating expenses for wages and office rent. The increase in telecommunication costs would not outweigh the benefits. Furthermore, the metro areas of North Dakota do not have an excess capacity in local services (e.g., schools, city services) which means the metro areas are faced with additional investments in public infrastructure that many rural communities would not be faced with. The economic benefits to rural areas could be substantial; a satellite office with 5 employees in Bowman, North Dakota, would have the same relative impact as a new employer with 209 jobs in Bismarck.

description: We consider a new phenomenological model for a $1/f^μ$ classical intermittent noise and study its effects on the dephasing of a two-level system. Within this model, the evolution of the relative phase between the $|\pm>$ states is described as a continuous time random walk (CTRW). Using renewal theory, we find exact expressions for the dephasing factor and identify the physically relevant various regimes in terms of the coupling to the noise. In particular, we point out the consequences of the non-stationarity and pronounced non-Gaussian features of this noise, including some new anomalous and aging dephasing scenarii.

description: This report provides estimates of the lignite industry's contribution to the North Dakota economy, using key economic indicators such as retail trade activity, personal income, total business activity, employment, and tax revenues. The estimates are based on actual industry expenditures for 1999 and projected expenditures for 2000. This analysis contains two measures of the relative importance of the lignite energy industry in North Dakota. First, the industry's share of the state's total sales to final demand (or exports) is evaluated. Second, the business volume generated by the industry is compared to the total gross business volume for the state. Expenditures were obtained from a survey of firms involved in lignite related activities (mining or conversion) in North Dakota. Finally, wages paid by the coal mining sector are compared to those paid by other sectors of the state economy.

description: We present experimental evidence for small-moment magnetism below the ferromagnetic transition temperature (T_c3 = 183 K) in the quasi-one-dimensional metal BaIrO_3. Further, we identify rearrangement of the local magnetic moment distribution, which leaves the bulk magnetization unchanged, at the Mott-like transition (T_c1 = 26 K). These results are only possible via muon-spin relaxation ($μ$SR) techniques, since neutron scattering studies are hindered by the large absorption of neutrons by Ir. The low temperature characteristics of this compound, as revealed by $μ$SR, are unconventional, and suggest that its magnetic properties are driven by changes occuring at the Fermi surface due to the formation of a charge-density wave state.

description: The purpose of this paper is to review past trade relations in the grains sector between the United States and Canada and to document trade barriers and the potential for the evolution of reciprocal trade. Historical trade flows between the United States and Canada in the grains sector are reviewed. Terms of recent trade agreements and other trade restrictions are described. Then, some of the important differences in the marketing system are described and compared as well as changes in the Canadian grain marketing system. Finally, the concept of reciprocal access is developed in the context of the evolving trading relations between these two countries.
OVNI (Object Virtual Network Integrator) : a new fast algorithm for the simulation of very large electric networks in real time
Creators: name: Linares-Rojas, Luis R.
Publisher: name: University of British Columbia
Year: 2009

description: A portable fast algorithm for solving power electric and electronic networks, and its implementation in the real-time simulator OVNI, are introduced. The implementation of OVNI, object virtual network integrator, on an off-the-shelf hardware platform, a 400 MHz Pentium-II workstation is presented. Simplified fast-models, based on those used by the EMTP1 , are included for the network elements: lumped resistors, capacitors, inductors —both linear and nonlinear— and a constant parameters transmission lines model. Real-time models for HVDC rectifying and inverting bridges, and for the corresponding PIcontrollers, using node hiding, were created specially for OVNI and reported in this thesis. Core saturation and zero sequence flux in three phase core transformers are modelled. Fast non-linear models are included for current and potential transformers. A fast modelling scheme to account for switching operations is presented, and its successful implementation on an industrial product, reported. Multilayer segmentation of the network, topological segmentation followed by MATE2 segmentation, the node hiding technique, and a history sources limited encapsulation scheme are introduced. Two fast asynchronous commutation modelling techniques —DSDI3 and BIFE4— to eliminate spikes and numerical oscillations are introduced. Industrial real-time test cases are included for power system protective relays, and for high-voltage DC bridges and their corresponding controllers.

description: Energy relaxation of photo-excited charge carriers is of significant fundamental interest and crucial for the performance of monolayer (1L) transition metal dichaclogenides (TMDs) in optoelectronics. We measure light scattering and emission in 1L-WSe$_2$ close to the laser excitation energy (down to~$\sim$0.6meV). We detect a series of periodic maxima in the hot photoluminescence intensity, stemming from energy states higher than the A-exciton state, in addition to sharp, non-periodic Raman lines related to the phonon modes. We find a period $\sim$15meV for peaks both below (Stokes) and above (anti-Stokes) the laser excitation energy. We detect 7 maxima from 78K to room temperature in the Stokes signal and 5 in the anti-Stokes, of increasing intensity with temperature. We assign these to phonon cascades, whereby carriers undergo phonon-induced transitions between real states in the free-carrier gap with a probability of radiative recombination at each step. We infer that intermediate states in the conduction band at the $Λ$-valley of the Brillouin zone participate in the cascade process of 1L-WSe$_2$. The observations explain the primary stages of carrier relaxation, not accessible so far in time-resolved experiments. This is important for optoelectronic applications, such as photodetectors and lasers, because these determine the recovery rate and, as a consequence, the devices' speed and efficiency.

Influence of local treatments of convection upon solar p mode excitation rates

description: We compute the rates P at which acoustic energy is injected into the solar radial p modes for several solar models. The solar models are computed with two different local treatments of convection: the classical mixing-length theory (MLT hereafter) and Canuto et al (1996)'s formulation (CGM hereafter). Among the models investigated here, our best models reproduce both the solar radius and the solar luminosity at solar age and the observed Balmer line profiles. For the MLT treatment, the rates P do depend significantly on the properties of the atmosphere whereas for the CGM's treatment the dependence of P on the properties of the atmosphere is found smaller than the error bars attached to the seismic measurements. The excitation rates P for modes associated with the MLT models are significantly underestimated compared with the solar seismic constraints. The CGM models yield values for P closer to the seismic data than the MLT models. We conclude that the solar p-mode excitation rates provide valuable constraints and according to the present investigation clearly favor the CGM treatment with respect to the MLT, although neither of them yields values of P as close to the observations as recently found for 3D numerical simulations.

description: Over one-half (57%) of the 1,757 respondents to a random survey of North Dakota households agree that all remaining natural wetlands in the state should be preserved. Nearly two- thirds (63%) of the respondents support compensating landowners for preserving wetlands. However, the amount most respondents were willing to pay landowners was $10 or less per year. Over one-third (38%) of the respondents used wetlands for outdoor recreation. Responses were somewhat related to socioeconomic characteristics such as age, gender, income, education, and place of residence.
