description: 2MASS J20395358+4222505 is an obscured early B supergiant near the massive OB star association Cyg OB2. Despite its bright infrared magnitude (K$_{s}$=5.82) it has remained largely ignored because of its dim optical magnitude (B=16.63, V=13.68). In a previous paper we classified it as a highly reddened, potentially extremely luminous, early B-type supergiant. We obtained its spectrum in the U, B and R spectral bands during commissioning observations with the instrument MEGARA@GTC. It displays a particularly strong H$α$ emission for its spectral type, B1 Ia. The star seems to be in an intermediate phase between super- and hypergiant, a group that it will probably join in the near (astronomical) future. We observe a radial velocity difference between individual observations and determine the stellar parameters, obtaining T$_{eff}$ = 24000 K, logg$_{c}$= 2.88 $\pm$ 0.15. The rotational velocity found is large for a B-supergiant, vsini= 110 $\pm$ 25 km s$^{-1}$. The abundance pattern is consistent with solar, with a mild C underabundance (based on a single line). Assuming that J20395358+4222505 is at the distance of Cyg OB2 we derive the radius from infrared photometry, finding R= 41.2 $\pm$ 4.0 R$_{\odot}$, log(L/L$_{\odot}$)= 5.71 $\pm$ 0.04 and a spectroscopic mass of 46.5 $\pm$ 15.0 M$_{\odot}$. The clumped mass-loss rate (clumping factor 10) is very high for the spectral type, $\dot{M}$ = 2.4x10$^{-6}$ M$_{\odot}$ a$^{-1}$. The high rotational velocity and mass-loss rate place the star at the hot side of the bi-stability jump. Together with the nearly solar CNO abundance pattern, they may also point to evolution in a binary system, J20395358+4222505 being the initial secondary.

Discovery of Spectroscopic Variations in the DAB White Dwarf GD 323

description: We report the discovery of spectroscopic variations in GD 323, the prototypical DAB white dwarf. Simultaneous optical spectroscopic observations over five consecutive nights of GD 323 and of PG 1234+482, a non-variable comparison DA white dwarf of similar brightness, are used to reveal quasi-periodic variations in both the hydrogen and helium absorption lines over a timescale of hours. The amplitude of the variation of the equivalent width of Hbeta is ~30 %. Moreover, the strength of the hydrogen lines is shown to vary in opposite phase from that of He I 4471. These results suggest that the model currently thought to be the most viable to account for the simultaneous presence of hydrogen and helium lines in GD 323, namely a static stratified atmosphere, may need to be reexamined. Instead, a model with an inhomogeneous surface composition, resulting perhaps from the dilution of a thin hydrogen atmosphere with the underlying helium convection zone, may be a better representation of GD 323. The observed variation timescale of ~3.5 hours is consistent with the slow rotation rate of white dwarf stars.

description: We measured the thickness of an insensitive surface layer of a PIN photodiode, Hamamatsu S3590-06, used in the Tokyo Axion Helioscope. We made alpha-particles impinge on the PIN photodiode in various incidence angles and measured the pulse height to estimate the thickness of the insensitive surface layer. This measurement showed its thickness was $0.31 \pm 0.02 μm$ on the assumption that the insensitive layer consisted of Si. We calculated the peak detection efficiency for low energy x-rays in consideration of the insensitive layer and escape of x-rays and Auger electrons. This result showed the efficiency for 4-10keV x-rays was more than 95%.

Associations of songbirds with their habitat in the Garry Oak (Quercus garryana) ecosystems of Victoria, British Columbia, Canada

description: Urbanization fragments habitat, which affects bird abundance and distribution. This study tested the effect of urbanization on birds in fragments of Garry oak (Quercus garryana) and Douglas-fir (Pseudotsuga menziesii) ecosystems in Victoria, British Columbia. Birds were surveyed along transects in seven Garry oak patches in May and June of 2000. The patches were stratified by surrounding habitat type; four were surrounded by coniferous forest and three were surrounded by urban development. Birds were also surveyed in these adjacent habitats. Relative species abundance was determined using point counts along transects and territory mapping. Associations between bird abundances and urbanization in the landscape, patch size and Garry oak stem volume were tested. Linear regression models related environmental variables to the abundances of 17 common birds. The best model was chosen via Akaike's Information Criterion. For 42 birds, relationships between species composition, adjacent habitat type and vegetation composition were analyzed with detrended and canonical correspondence analysis and cluster analysis. For the 17 common species, 10 were strongly associated with the level of urbanization in the surrounding landscape. Seven species were associated with Garry oak stem volume, three positively and five negatively. Garry oak patches surrounded by urbanization had substantially different species assemblages than those surrounded by coniferous forest, in part due to the influence of coniferous trees in Garry oak patches. The results indicate that the level of urbanization in the broader landscape and tree composition in patches are significant factors associated with Garry oak bird assemblages. Conservation of Victoria's songbirds requires conserving and restoring a spectrum of habitats, from open savanna to closed-canopy coniferous forests. Management should be targeted at the landscape-scale and explicitly consider the extent of urbanization in the landscape.
Numerical Simulation of Rotating Accretion Disk Around the Schwarzschild Black Hole Using GRH Code

description: The 2D time dependent solution of thin accretion disk in a close binary system have been presented on the equatorial plane around the Schwarzschild black hole. To do that, the special part of the General Relativistic Hydrodynamical(GRH) equations are solved using High Resolution Shock Capturing (HRSC) schemes. The spiral shock waves on the accretion disk are modeled using perfect fluid equation of state with adiabatic indices $γ= 1.05, 1.2$ and 5/3. The results show that the spiral shock waves are created for gammas except the case $γ=5/3$. These results consistent with results from Newtonian hydrodynamic code except close to black hole. Newtonian approximation does not give good solution while matter closes to black hole. Our simulations illustrate that the spiral shock waves are created close to black hole and the location of inner radius of spiral shock wave is around $10M$ and it depends on the specific heat rates. We also find that the smaller $γ$ is the more tightly the spiral winds.

A FARM-LEVEL ANALYSIS OF SOIL LOSS CONTROL: MODELING THE PROBABILISTIC NATURE OF ANNUAL SOIL LOSS

description: The Conservation Compliance provision of the Food Security Act of 1985 requires all farmers who farmed highly erodible land prior to the passage of the Act to have a locally approved conservation plan fully implemented by 1995 or lose eligibility for numerous farm programs. Soil loss estimates of various crop, tillage practices, and conservation practices, however, are stochastic in nature. A farm planning model is suggested that allows for stochastic soil loss estimates. The model is compared to other models used in farm level soil conservation studies. The model shows promise as a more acceptable tool in that the farm plans are more likely to be acceptable to the farmer.

We are interested in evaluating the quantities acceleration, rotation, expansion, shear, shear invariant and expansion rate. These kinematical quantities are discussed both in co-moving as well as in non-co-moving coordinates (only in radial direction). Finally, we would discuss the singularity feature of these solutions. It is expected that these properties would help in exploring some interesting features of the self-similar solutions.

description: Production agriculture in the Northeast represents a declining share of national agricultural production. Some of the characteristics of Northeast agriculture that affect its future are (1) an unfavorable resource base; (2) proximity to population centers; and (3) a diversity of enterprises. Major issues affecting the future include changing technology, changing structure, competitive advantage, regulation, and labor supply and demand. The role of specialty crops in Northeast agriculture was examined. Pesticide regulation and the labor requirement for specialty crops are serious constraints to widespread adoption.

description: A precision measurement of the double-differential production cross-section, ${d^2 σ^{π^+}}/{d p dΩ}$, for pions of positive charge, performed in the HARP experiment is presented. The incident particles are protons of 12.9 GeV/c momentum impinging on an aluminium target of 5% nuclear interaction length. The measurement of this cross-section has a direct application to the calculation of the neutrino flux of the K2K experiment. After cuts, 210000 secondary tracks reconstructed in the forward spectrometer were used in this analysis. The results are given for secondaries within a momentum range from 0.75 GeV/c to 6.5 GeV/c, and within an angular range from 30 mrad to 210 mrad. The absolute normalization was performed using prescaled beam triggers counting protons on target. The overall scale of the cross-section is known to better than 6%, while the average point-to-point error is 8.2%.

description: For certain negative rational numbers k0, called singular values, and associated with the symmetric group S_N on N objects, there exist homogeneous polynomials annihilated by each Dunkl operator when the parameter k = k0. It was shown by de Jeu, Opdam and the author (TAMS 346(1994),237-256) that the singular values are exactly the values m/n with 2<=n<=N, m = 1,2... and m/n is not an integer. For each pair (m,n) satisfying these conditions there is a unique irreducible S_N-module of singular polynomials for the singular value -m/n. The existence of these polynomials was established by the author (IMRN 2004,#67,3607-3635). The uniqueness is proven in the present paper. By using Murphy's (J. Alg. 69(1981), 287-297) results on the eigenvalues of the Murphy elements, the problem of existence of singular polynomials is first restricted to the isotype of a partition of N (corresponding to an irreducible representation of S_N) such that (n/gcd(m,n)) divides t+1 for each part t of the partition except the last one. Then by arguments involving nonsymmetric Jack polynomials it is shown that the assumption that the second part of the partition is greater than or equal to n/gcd(m,n) leads to a contradiction.This shows that the singular polynomials are exactly those already determined.

The group has created the opportunity for fruitful conversations in this area and has brought together voices from a range of different disciplinary backgrounds. This document shows an example of how conversations of this type can benefit and advance computational methods and understandings in and between the humanities and data science, bringing together a diverse community. We believe the Turing can act as a nexus of discussion on humanities and data science research at the national (and international) level, in areas such as education strategy, research best practices, and funding policy, and can promote and encourage research activities in this interdisciplinary area.

description: During their formation, emerging protoplanets tidally interact with their natal disks. Proto-gas-giant planets, with Hills radius larger than the disk thickness, open gaps and quench gas flow in the vicinity of their orbits. It is usually assumed that their type II migration is coupled to the viscous evolution of the disk. Although this hypothesis provides an explanation for the origin of close-in planets, it also encounter predicament on the retention of long-period orbits for most gas giant planets. Moreover, numerical simulations indicate that planets migrations are not solely determined by the viscous diffusion of their natal disk. Here we carry out a series of hydrodynamic simulations combined with analytic studies to examine the transition between different paradigms of type II migration. We find a range of planetary mass for which gas continues to flow through a severely depleted gap so that the surface density distribution in the disk region beyond the gap is maintained in a quasi-steady state. The associated gap profile modifies the location of corotation \& Lindblad resonances. In the proximity of the planet's orbit, high-order Lindblad \& corotation torque are weakened by the gas depletion in the gap while low-order Lindblad torques near the gap walls preserves their magnitude. Consequently, the intrinsic surface density distribution of the disk determines delicately both pace and direction of planets' type II migration. We show that this effect might stall the inward migration of giant planets and preserve them in disk regions where the surface density is steep.

description: Short- and long-run Hicksian and Marshallian elasticities are estimated, along with Morishima elasticities of substitution, using a restricted profit function and a series of decomposition equations. Convexity in prices and concavity in quasi-fixed factors of the restricted profit function are simultaneously imposed using Bayesian techniques. The empirical model is disaggregated in the input side, utilizes a Fuss-quadratic flexible functional form, incorporates the impact of agricultural policies, and introduces a new weather index. The methodology is applied to Illinois's agriculture, and implications for agriculture in the Corn Belt and the Northeast are briefly discussed.

description: The catalytic performance of these Ta2O5 nanoparticles was evaluated towards the photodegradation of nitrogen oxides (NOx) under UV–vis irradiation at room temperature. In comparison to the commercial TiO2 (Aeroxide P25 powder: 20 % rutile/80 % anatase, 50 m2/g), traditionally considered state-of-the-art material for the NOx degradation, as-synthesized Ta2O5 (41 m2/g specific surface area) nanoparticles offers NOx remediation with minimal toxic NO2 and excellent stability under UV irradiation. A 2-fold increase in the UV-photonic-efficiency (∼0.64 %) of Ta2O5 is observed compared to TiO2 P25 (∼0.30 %). NO conversion using Ta2O5 was noted to be 18.6 % compared to 8.8 % for TiO2.

description: We consider the possibility that the dark matter is coupled through its mass to a scalar field associated with the dark energy of the Universe. In order for such a field to play a role at the present cosmological distances, it must be effectively massless at galactic length scales. We discuss the effects of the field on the distribution of dark matter in galaxy halos. We show that the profile of the distribution outside the galaxy core remains largely unaffected and the approximately flat rotation curves persist. The dispersion of the dark matter velocity is enhanced by a potentially large factor relative to the case of zero coupling between dark energy and dark matter. The counting rates in terrestrial dark matter detectors are similarly enhanced. Existing bounds on the properties of dark matter candidates can be extended to the coupled case, by taking into account the enhancement factor.

description: Metropolitan agriculture is not homogeneous. This paper delves beneath metropolitan county averages using data on individual farms in the Northeast classified into three statistically distinct types. A small group of adaptive farms profit from intensive production on smaller acreage to accommodate themselves to the urban environment. Traditional farms have increased costs and pressures on their more extensive operations without compensating increases in revenue from better-adapted enterprises. A large group of recreational farms subsidize small-farm activities from nonfarm income. Operating characteristics of each farm type are presented and their importance to metropolitan agriculture is assessed. Implications for preserving farming and farmland in the Northeast are drawn.

description: Double-beta processes play a key role in the exploration of neutrino and weak interaction properties, and in the searches for effects beyond the Standard Model. During the last half century many attempts were undertaken to search for double-beta decay with emission of two electrons, especially for its neutrinoless mode ($0\nu2β^-$), the latter being still not observed. Double-electron capture (2EC) was not in focus so far because of its in general lower transition probability. However, the rate of neutrinoless double-electron capture ($0\nu2$EC) can experience a resonance enhancement by many orders of magnitude in case the initial and final states are energetically degenerate. In the resonant case, the sensitivity of the $0\nu2$EC process can approach the sensitivity of the $0\nu2β^-$ decay in the search for the Majorana mass of neutrinos, right-handed currents, and other new physics. We present an overview of the main experimental and theoretical results obtained during the last decade in this field. The experimental part outlines search results of 2EC processes and measurements of the decay energies for possible resonant $0ν$2EC transitions. An unprecedented precision in the determination of decay energies with Penning traps has allowed one to refine the values of the degeneracy parameter for all previously known near-resonant decays and has reduced the rather large uncertainties in the estimate of the $0\nu2$EC half-lives. The theoretical part contains an updated analysis of the electron shell effects and an overview of the nuclear structure models, in which the nuclear matrix elements of the $0\nu2$EC decays are calculated. One can conclude that the decay probability of $0ν$2EC can experience a significant enhancement in several nuclides.

description: This article investigates the possible negative effects of bovine somatotropin (bST) and antibiotic use in cows on fluid-milk consumption in New York State. Based on data from a consumer survey, the potential change in milk consumption due to bST and antibiotic use is estimated. In addition, the current perceptions of consumers about bST and antibiotics are measured, and the significant socioeconomic, demographic, and attitudinal characteristics of consumers that are related to their milk-consumption response to bST are identified. Depending upon consumer awareness of bST, the results indicate that milk consumption in New York State could decrease by 5.5% to 15.6% if bST is approved. The results also suggest that antibiotic use in cows could decrease milk consumption by 1.6% to 7%, depending upon consumer awareness. A major implication is that education will likely play an important role in influencing consumers' attitudes and perceptions about both bST and antibiotics.

description: The MBE-grown GaAs/AlGaAs superlattice with Si-doped barriers has been used to study a 3D-2D transition under the influence of the in-plane component of applied magnetic field. The longitudinal magnetoresistance data measured in tilted magnetic fields have been interpreted in terms of a simple tight-binding model. The data provide values of basic parameters of the model and make it possible to reconstruct the superlattice Fermi surface and to calculate the density of states for the lowest Landau subbands. Positions of van Hove singularities in the DOS agree excellently with magnetoresistance oscillations, confirming that the model describes adequately the magnetoresistance of strongly coupled semiconductor superlattices.

Addressing uncertainty in forest planning
Creators: name: Cerda, Juan Pablo
Publisher: name: University of British Columbia

description: Forests are complex 'systems' with forest ecosystem, resource, stakeholder and policy 'subsystems'. Knowledge about forest systems is always incomplete, and uncertainty pervades decision-making. Uncertainty produces risk of losses and potential opportunities, which have to be recognized and characterized. From then, the best probabilistic predictions, guesses, judgments, and scenario models can be made. Good planning addresses uncertainty, and adapts to changes. It is based on constant learning, and includes processes that enable feedback on past outcomes to inform future planning. British Columbia (BC)'s forest land area is 60.6 million hectares. Most of it is publicly owned, and forest harvesting is licensed. Licensees must prepare Forest Development Plans (FDP's), which describe specific areas proposed for harvest. These plans allow for discussion and resolution of environmental and socioeconomic issues. The annual cost of preparing and reviewing FDPs province-wide exceeds $30 million. In spite of this expense, actual outcomes routinely differ from those described in the original FDPs because of uncertainty. This is due mostly to natural disturbance events, shifts in social values or policy, and timber market changes. FDPs are constantly amended. The annual cost of preparation and review exceeds $12 million. Furthermore, unexpected outcomes and frequent amendments undermine public confidence in the planning process. In addition to highlighting the weaknesses in the current planning processes, a method to address uncertainty through better forest planning in BC is proposed. Complexity in the forest system and uncertainty in planning have a spatial dimension, which is representable and analyzable using Geographic Information System (GIS) tools. Ecosystem dynamics, and the impact on biophysical attributes of the landscape of changes in resources prices and policies, and people's values can be mapped, and spatially matched with unexpected outcomes of planning. Using the "SAFEPLAN" method these outcomes can be explained, and improvements to the planning processes can be recommended. Results obtained for southeastern BC show how the adoption of this method could increase the efficacy of forest plans, and improve the cost-effectiveness of the whole planning process, including its role in the proposed context for forest planning in BC.

description: In this study, we examine citizens’ perceptions of recent livestock production in Germany. Thereby, we focus against the backdrop of seven animal species-specific guidelines written by Scientific Advisory Board on Agricultural Policy, Food and Consumer Health Protection at the Federal Ministry (WBA, 2015). We combine a qualitative study with focus group discussions about pig, cattle and poultry production systems and a quantitative online survey with factor analysis. Based upon the findings of the exploratory factor analysis, a cluster analysis was conducted to assign respondents to groups. The results provide an overview of citizens’ recent perceptions and attitudes, show differences and commonalities with regard to the three main livestock production systems pig, cattle and poultry production. We sum up our qualitative results as thesis for each animal species. Furthermore, we show relevant factors for respondents and divide them into clusters. We discuss these results against the background of the guidelines stated by the WBA.

description: Jeans showed analytically that, in an infinite uniform-density isothermal gas, plane-wave perturbations collapse to dense sheets if their wavelength, $λ$, satisfies $λ> λ_{_{\rm JEANS}} = (πa^2 / G ρ_{_0})^{1/2}$ (where $a$ is the isothermal sound speed and $ρ_{_0}$ is the unperturbed density); in contrast, perturbations with smaller $λ$ oscillate about the uniform density state. Here we show that Smoothed Particle Hydrodynamics reproduces these results well, even when the diameters of the SPH particles are twice the wavelength of the perturbation. Our simulations are performed in 3-D with initially settled (i.e. non-crystalline) distributions of particles. Therefore there exists the seed noise for artificial fragmentation, but it does not occur. We conclude that, although there may be -- as with any numerical scheme -- `skeletons in the SPH cupboard', a propensity to fragment artificially is evidently not one of them.

Productivity Analysis

description: To examine productivity growth in New Jersey's food-processing sector, this study conducts a joint analysis of total and partial factor productivity indexes. Results indicate growing material intensity, declining labor and capital intensities, and relatively slow material productivity growth. However, due to the high cost share of material inputs, material productivity growth contributed more to total factor productivity growth than did growth in the productivity of any other input. In fact, almost half of the growth in overall productivity is attributed to material productivity growth. Results also suggest that the 1973 decline in total factor productivity was characterized by greater decline in material productivity than in the productivities of labor and capital.

description: We have prepared crystalline nanowires (diameter ~ 50 nm, length ~ a few microns) of the charge ordering manganite Pr_0.5Ca_0.5Mn_O3 using a low reaction temperature hydrothermal method and characterized them using X-ray diffraction, transmission electron microscopy, SQUID magnetometry and electron magnetic resonance measurements. While the bulk sample shows a charge ordering transition at 245 K and an antiferromagnetic transition at 175 K, SQUID magnetometry and electron magnetic resonance experiments reveal that in the nanowires phase, a ferromagnetic transition occurs at ~ 105 K. Further, the antiferromagnetic transition disappears and the charge ordering transition is suppressed. This result is particularly significant since the charge order in Pr_0.5Ca_0.5MnO_3 is known to be very robust, magnetic fields as high as 27 T being needed to melt it.

Magnetic and ferroelectric properties of Sr$_{1-x}$Ba$_{x}$MnO$_3$ from first principles

description: Density functional theory (DFT) calculations are used to study the magnetic and ferroelectric properties of Sr$_{1-x}$Ba$_{x}$MnO$_3$, with focus on $x=0.5$, under isotropic volume expansion/compression and biaxial strain. Our results indicate that, unexpectedly, Ba substitution alters the electronic structure in a way that, at fixed lattice parameter, notably enhances the interatomic magnetic exchange interactions. However, increasing Ba-content also causes a volume expansion which tends to weaken these interactions, leading to a net effect of weakly suppressed magnetism, as observed in experiments. The ferroelectric properties, on the other hand, are found to be less affected by changes in the electronic structure and can largely be understood in terms of the volume expansion caused by Ba-substitution. The calculated electric polarization as a function of biaxial strain in Sr$_{1-x}$Ba$_{x}$MnO$_3$ for $x=0$ and $x=0.5$, shows that the difference between the two is mainly due to differences in the magnetic order at certain strain values, accompanied by enormous magnetoelectric coupling.

description: One potentially serious problem in evaluating the effectiveness of extension programs is that participants are not picked at random. Self-selection can be a problem, and it can be compounded if extension officials concentrate on the most progressive farms. This study explores the relationships between adoption of maize high-yielding varieties (HYVs) and participation in field trials intended to foster HYV usage, drawing on data from Swaziland. Results indicate that it is impossible to say if field trials had any effect on adoption. Participating farms used more HYVs, but this could have been due to self-selection or the government's selection process.

description: This study's objective is to identify and understand the factors important to hardwood processors' location decisions in the northern and central Appalachian region. Concepts from neoclassical and behavioral location theories were integrated to develop a general framework for analyzing these decisions. Logit regression analysis was used to determine those establishment characteristics related to the likelihood of location search. To a great extent, establishments locate based on personal ties and do not conduct searches. Most variables found to influence the likelihood of search are not controllable by state or local governments. The implications are that existing establishments should be targeted for retention and expansion, rather than focusing on recruitment.

description: We study many-class few-shot (MCFS) problem in both supervised learning and meta-learning settings. Compared to the well-studied many-class many-shot and few-class few-shot problems, the MCFS problem commonly occurs in practical applications but has been rarely studied in previous literature. It brings new challenges of distinguishing between many classes given only a few training samples per class. In this paper, we leverage the class hierarchy as a prior knowledge to train a coarse-to-fine classifier that can produce accurate predictions for MCFS problem in both settings. The propose model, "memory-augmented hierarchical-classification network (MahiNet)", performs coarse-to-fine classification where each coarse class can cover multiple fine classes. Since it is challenging to directly distinguish a variety of fine classes given few-shot data per class, MahiNet starts from learning a classifier over coarse-classes with more training data whose labels are much cheaper to obtain. The coarse classifier reduces the searching range over the fine classes and thus alleviates the challenges from "many classes". On architecture, MahiNet firstly deploys a convolutional neural network (CNN) to extract features. It then integrates a memory-augmented attention module and a multi-layer perceptron (MLP) together to produce the probabilities over coarse and fine classes. While the MLP extends the linear classifier, the attention module extends the KNN classifier, both together targeting the "few-shot" problem. We design several training strategies of MahiNet for supervised learning and meta-learning. In addition, we propose two novel benchmark datasets "mcfsImageNet" and "mcfsOmniglot" specially designed for MCFS problem. In experiments, we show that MahiNet outperforms several state-of-the-art models on MCFS problems in both supervised learning and meta-learning.

description: We revisit the interlayer tunneling theory of high temperature superconductors and formulate it as a mechanism by which the striking systematics of the transition temperature within a given homologous series can be understood. We pay attention not only to the enhancement of pairing, as was originally suggested, but also to the role of competing order parameters that tend to suppress superconductivity, and to the charge imbalance between inequivalent outer and inner CuO2 planes in a unit cell. Calculations based on a generalized Ginzburg-Landau theory yield results that bear robust and remarkable resemblance to experimental observations.
