description: We introduce a unified framework for random forest prediction error estimation based on a novel estimator of the conditional prediction error distribution function. Our framework enables simple plug-in estimation of key prediction uncertainty metrics, including conditional mean squared prediction errors, conditional biases, and conditional quantiles, for random forests and many variants. Our approach is especially well-adapted for prediction interval estimation; we show via simulations that our proposed prediction intervals are competitive with, and in some settings outperform, existing methods. To establish theoretical grounding for our framework, we prove pointwise uniform consistency of a more stringent version of our estimator of the conditional prediction error distribution function. The estimators introduced here are implemented in the R package forestError.

description: This paper presents a detailed description, analysis and example of practical application of a wide frequency band voltage-to-current converter. The converter is characterized by a combination of positive and negative feedback loops. This feature allows compensation for parasitic impedance connected in parallel with the useful load, which in turn keeps an excitation current flowing through the useful load independent of its impedance. The simplicity of the circuit and its good electrical properties are additional advantages of the scheme.

description: We have recently introduced a realistic, covariant, interpretation for the reduction process in relativistic quantum mechanics. The basic problem for a covariant description is the dependence of the states on the frame within which collapse takes place. A suitable use of the causal structure of the devices involved in the measurement process allowed us to introduce a covariant notion for the collapse of quantum states. However, a fully consistent description in the relativistic domain requires the extension of the interpretation to quantum fields. The extension is far from straightforward. Besides the obvious difficulty of dealing with the infinite degrees of freedom of the field theory, one has to analyze the restrictions imposed by causality concerning the allowed operations in a measurement process. In this paper we address these issues. We shall show that, in the case of partial causally connected measurements, our description allows us to include a wider class of causal operations than the one resulting from the standard way for computing conditional probabilities. This alternative description could be experimentally tested. A verification of this proposal would give a stronger support to the realistic interpretations of the states in quantum mechanics.

description: Bollobás and Nikiforov [J. Combin. Theory, Ser. B. 97 (2007) 859--865] conjectured the following. If $G$ is a $K_{r+1}$-free graph on at least $r+1$ vertices and $m$ edges, then $λ^2_1(G)+λ^2_2(G)\leq \frac{r-1}{r}\cdot2m$, where $λ_1(G)$ and $λ_2(G)$ are the largest and the second largest eigenvalues of the adjacency matrix $A(G)$, respectively. In this paper, we confirm the conjecture in the case $r=2$, by using tools from doubly stochastic matrix theory, and also characterize all families of extremal graphs. Motivated by classic theorems due to Erdős and Nosal respectively, we prove that every non-bipartite graph $G$ of order $n$ and size $m$ contains a triangle, if one of the following is true: (1) $λ_1(G)\geq\sqrt{m-1}$ and $G\neq C_5\cup (n-5)K_1$; and (2) $λ_1(G)\geq λ_1(S(K_{\lfloor\frac{n-1}{2}\rfloor,\lceil\frac{n-1}{2}\rceil}))$ and $G\neq S(K_{\lfloor\frac{n-1}{2}\rfloor,\lceil\frac{n-1}{2}\rceil})$, where $S(K_{\lfloor\frac{n-1}{2}\rfloor,\lceil\frac{n-1}{2}\rceil})$ is obtained from $K_{\lfloor\frac{n-1}{2}\rfloor,\lceil\frac{n-1}{2}\rceil}$ by subdividing an edge. Both conditions are best possible. We conclude this paper with some open problems.

description: Diese Bachelorarbeit befasst sich mit der Frage, wie es gelingen kann, Compassion Fatigue in der Sozialen Arbeit durch Maßnahmen der Selbstfürsorge vorzubeugen. Hierzu wurde das amerikanische Konzept Compassion Fatigue untersucht, seine Relevanz für die Soziale Arbeit in Deutschland herausgearbeitet und präventive Maßnahmen der individuellen und professionellen Selbstfürsorge vorgestellt. Im Rahmen der Literaturrecherche wurde insbesondere englischsprachige Primärliteratur des Forschers C. R. Figley berücksichtigt. Als Ergebnis kann festgehalten werden, dass Compassion Fatigue eine Kumulation verschiedener Belastungsfaktoren darstellt und sich u.a. aus sekundärer Traumatisierung und Burnout zusammensetzt. In Deutschland wurde Compassion Fatigue bei Sozialarbeiter_innen bislang nicht statistisch erfasst. Die internationale Literatur verdeutlicht jedoch, dass Compassion Fatigue eine ernstzunehmende Berufsgefahr für Sozialarbeiter_innen darstellt. Sozialarbeiter_innen sollten daher in der Ausbildung und Weiterbildung für das Thema Compassion Fatigue sensibilisiert werden. Individuelle und professionelle Maßnahmen der Selbstfürsorge können dabei behilflich sein, die biopsychosoziale Gesundheit von Sozialarbeiter_innen zu erhalten.

description: We examined gender differences in bidding and learning behavior in Second Price Auctions (SPAs). Although bidding one’s true value is a weakly dominant strategy in SPAs, overbidding has been common and persistent in laboratory SPAs, i.e., bidding above one’s value. In our study, we found that inexperienced women overbid more than inexperienced men when they were provided with endowment money in the auctions. However, when participants were asked to bid using their own money, women became more cautious, bidding lower and closer to the optimal strategy (true value) even without experiences, while inexperienced men still overbid significantly deviating from the optimal strategy. As men gained more experiences, they learned from costly overbidding and eventually lowered their bids to the same level as those of women’s bids. In conclusion, we found that although women and men initially behaved differently in SPAs, both genders would eventually bid according to the optimal strategy and obtain the same outcome given sufficient learning experiences.

description: Recent sign-problem-free quantum Monte Carlo simulations of (2+1)-dimensional lattice quantum electrodynamics (QED$_3$) with $N_f$ flavors of fermions on the square lattice have found evidence of continuous quantum phase transitions between a critical phase and a gapped valence-bond-solid (VBS) phase for flavor numbers $N_f=4$, $6$, and $8$. We derive the critical theory for these transitions, the chiral $O(2)$ QED$_3$-Gross-Neveu model, and show that the latter is equivalent to the gauged Nambu--Jona-Lasinio model. Using known large-$N_f$ results for the latter, we estimate the order parameter anomalous dimension and the correlation length exponent for the transitions mentioned above. We obtain large-$N_f$ results for the dimensions of fermion bilinear operators, in both the gauged and ungauged chiral $O(2)$ Gross-Neveu models, which respectively describe the long-distance power-law decay of two-particle correlation functions at the VBS transition in lattice QED$_3$ and the Kekulé-VBS transition for correlated fermions on the honeycomb lattice.

description: We present a catalogue of previously unpublished optical and infrared photometry for a sample of 162 emission-line objects and shell stars visible from the southern hemisphere. The data were obtained between 1978 and 1997 in the Walraven (WULBV), Johnson/Cousins (UBV(RI)_c) and ESO and SAAO near-infrared (JHKLM) photometric systems. Most of the observed objects are Herbig Ae/Be (HAeBe) stars or HAeBe candidates appearing in the list of HAeBe candidates of Thé et al. (1994), although several B[e] stars, LBVs and T Tauri are also included in our sample. For many of the stars the data presented here are the first photo-electric measurements in the literature. The resulting catalogue consists of 1809 photometric measurements. Optical variability was detected in 66 out of the 116 sources that were observed more than once. 15 out of the 50 stars observed multiple times in the infrared showed variability at 2.2 microns (K band).

description: In this study, the annual GFSIs of Taiwan over the past 15 years were computed to investigate the association between food security, food self-sufficiency rate, and trade liberalization. Within the past 15 years, there were significantly sharp declines in 2002 and 2008. We inferred that the main reason for the sharp declines in 2002 is the import tariff decrease resulting from Taiwan’s entry into the World Trade Organization (WTO). And for 2008, an economic recession generated by the Global Financial Crisis should be responsible for the significant decline of Taiwan’s GFSI. In general, we found that there has been a steady growth trend of Taiwan’s GFSI since 2002 although food self-sufficiency rate has been declining. In conclusions, judging from the more comprehensive measurement of food security definition, trade liberalization improves the food security status of Taiwan.

description: Sufficient dimension reduction (SDR) using distance covariance (DCOV) was recently proposed as an approach to dimension-reduction problems. Compared with other SDR methods, it is model-free without estimating link function and does not require any particular distributions on predictors (see Sheng and Yin, 2013, 2016). However, the DCOV-based SDR method involves optimizing a nonsmooth and nonconvex objective function over the Stiefel manifold. To tackle the numerical challenge, we novelly formulate the original objective function equivalently into a DC (Difference of Convex functions) program and construct an iterative algorithm based on the majorization-minimization (MM) principle. At each step of the MM algorithm, we inexactly solve the quadratic subproblem on the Stiefel manifold by taking one iteration of Riemannian Newton's method. The algorithm can also be readily extended to sufficient variable selection (SVS) using distance covariance. We establish the convergence property of the proposed algorithm under some regularity conditions. Simulation studies show our algorithm drastically improves the computation efficiency and is robust across various settings compared with the existing method. Supplemental materials for this article are available.

description: These slides were presented at the eResearch 2011 meeting in Melbourne, Australia. The workshop covered both using a web browser as an OPeNDAP client as well as application-clients like Matlab and other tolls. Also covered are some issues relating to clients like configuration of the .dodsrc file to enable certificate-based authentication. This slide deck is the last of a total of four sets of slides (all uploaded to Zenodo) that were used for this 1/2 day workshop.

Summary: 

Session 4 focuses on accessing OPeNDAP servers with geospatial services, aggregation services, virtual datasets, and data libraries. A short tutorial is provided on accessing these services using an OPeNDAP- and OGC-enabled client application or web servlet.

An OPeNDAP crawler is introduced, capable of crawling THREDDS catalogs, forming aggregations, optimizing data reads, and writing NCML and EML. The crawler consists of six shell programs for various tasks like crawling catalogs, retrieving DDX responses, and writing metadata.

NcML is discussed, highlighting its features for modifying datasets, combining multiple files into aggregations, and creating logical datasets. A demonstration involves accessing an aggregation of data files from a service and discussing the challenges and benefits of using NcML.

Certificates for clients accessing OPeNDAP servers are addressed, detailing the process of obtaining and installing PKI certificates for both netCDF C and Java clients.

Various data discovery services and data analysis/visualization services are listed, including NASA's Global Change Master Directory and NOAA PMEL's Live Access Server.

The technology behind THREDDS Data Server (TDS) and Hyrax is briefly discussed, outlining features such as virtual directories, support for multiple data formats, OPeNDAP access, metadata generation, and security measures.

The TPAC Digital Library and other digital library services are mentioned as resources for accessing open data.

An exercise is provided, instructing participants to visit several websites related to open data and explore their content.

Finally, a list of OPeNDAP servers is provided, including those hosted by various institutions like the Bureau of Meteorology, CSIRO, ANU/NCI, OPeNDAP, inc., and TPAC.

description: Previous experimental and theoretical evidence has shown that convective flow may appear in granular fluids if subjected to a thermal gradient and gravity (Rayleigh-Bénard-type convection). In contrast to this, we present here evidence of gravity-free thermal convection in a granular gas, with no presence of external thermal gradients either. Convection is here maintained steady by internal gradients due to dissipation and thermal sources at the same temperature. The granular gas is composed by identical disks and is enclosed in a rectangular region. Our results are obtained by means of an event-driven algorithm for inelastic hard disks.

description: The main purpose of this paper is to rigorously establish the Strutinsky method from the least squares principle. Thus, it is the mathematical basis of this method (aspect often neglected) which is revisited in an extensive way. Some formulas previously given without demonstration or in a simplified way are set out here with all the details. In this respect, the most important mathematical properties of the averaging functions are also established in this paper. When some conditions are met, it turns out that Strutinsky's method is nothing more than a polynomial moving average of the semi-classical level density.

description: This paper examines the economic impact of alternative climate change scenarios on representative cash crop farms in Quebec and Ontario. Mixed Integer Dynamic Linear Programming models are used to determine the annual optimal land and labor allocations over a 30 year time horizon. In the modeling process, five climate scenarios are modeled, along with different combinations of CO2 enhancement and water limitation. Parameters, such as crop prices, costs of production, and crop yields, are simulated and projected into the future using various methods, such as Monte Carlo simulation, Crystal Ball Predictor and DSSAT cropping system model. Rotation and diversification constraints, as well as participation in public risk management programs are also incorporated into the optimization procedures. The results show that the economic impact of climate change varies by scenario, with the CO2 effect and water limitation having a more significant effect than the specific climate scenarios. Technology development, as well as the public insurance programs can contribute to the reduction of economic vulnerability.

description: We cast M-brane interactions including intersecting membranes and five-branes in manifestly gauge invariant form using an arrangement of higher dimensional Dirac surfaces. We show that the noncommutative gauge symmetry present in the doubled M-theory formalism involving dual 3-form and 6-form gauge fields is preserved in a form quantised over the integers. The proper context for discussing large noncommutative gauge transformations is relative cohomology, in which the 3-form transformation parameters become exact when restricted to the five-brane worldvolume. We show how this structure yields the lattice of M-theory charges and gives rise to the conjectured 7D Hopf-Wess-Zumino term.

While determining such a transformation is not considered glamorous in any sense of the word, it is nonetheless crucial for many modern autonomous systems. Indeed, an error of a few degrees in rotation or a few percent in translation can lead to 20 cm translation errors at a distance of 5 m when overlaying a LiDAR image on a camera image. The biggest impediments to determining the transformation accurately are the relative sparsity of LiDAR point clouds and systematic errors in their distance measurements. This paper proposes (1) the use of targets of known dimension and geometry to ameliorate target pose estimation in face of the quantization and systematic errors inherent in a LiDAR image of a target, and (2) a fitting method for the LiDAR to monocular camera transformation that fundamentally assumes the camera image data is the most accurate information in one's possession.

description: The mass-varying neutrino scenario is analyzed for three trial quintessence potentials (Ferreira-Joyce, inverse exponential, and thawing oscillating). The neutrino mass is generated via Yukawa coupling to the scalar field which represents dark energy. The inverse exponential and oscillating potentials are shown to successfully generate the neutrino masses in the range $m \sim 10^{-2}-10^{-3}~$eV and to yield the current dark energy density in the regime of the late-time acceleration of the Universe. Depending on the choice of potentials, the acceleration could occur in two different regimes: (1) the regime of instability, and (2) the stable regime. The first regime of instability is after the Universe underwent a first-order transition and is rolling toward the new stable vacuum. The imaginary sound velocity $c^2_s < 0$ in this regime implies growing fluctuations of the neutrino density (clustering). In the second regime, the Universe smoothly changes its stable states via a continuous transition. Since $c^2_s > 0$, the neutrino density is stable. For all cases the predicted late-time acceleration of the Universe is asymptotically very close to that of the $Λ$CDM model. Further extensions of the theory to modify the neutrino sector of the Standard Model and to incorporate inflation are also discussed. It is also shown that in the stable regimes where the neutrino mass is given by the minimum of the thermodynamic potential, the tree-level dynamics of the scalar field is robust with respect to one-loop bosonic and fermionic corrections to the potential.

description: This study analyze what contracting terms provides sufficient incentives for farmer’s to enter into a contract to produce energy beets for biofeul production. A stated choice experiment was designed to elicit farmer’s preferences to grow energy beet under alternative contractual arrangements. A latent class rank-ordered logit [LCROL] model is used to empirically analyze the effects of contract attributes, farmer’s risk preferences, and farm characteristics on willingness to adopt energy beet. The results shows that the way the contract mechanism is designed significantly affects farmer’s preference to rank contract alternatives. Few risk perception factors extracted from farmer’s response play a role on the preference of contracts.

description: The nature and physical properties of asteroids, in particular those orbiting in the near-Earth space, are of scientific interest and practical importance. Exoplanet surveys can be excellent resources to detect asteroids, both already known and new objects. This is due their similar observing requirements: large fields of view, long sequences, and short cadence. If the targeted fields are not located far from the ecliptic, many asteroids will cross occasionally the field of view. We present two complementary methodologies to identify asteroids serendipitously observed in large-area astronomical surveys. One methodology focuses on detecting already known asteroids using the Virtual Observatory tool SkyBoT, which predicts their positions and motions in the sky at a specific epoch. The other methodology applies the ssos pipeline, which is able to identify known and new asteroids based on their apparent motion. The application of these methods to the 6.4 deg 2 of the sky covered by the Wide-Field CAMera Transit Survey in the J-band is described. We identified 15 661 positions of 1 821 different asteroids. Of them, 182 are potential new discoveries. A publicly accessible online, Virtual Observatory compliant catalogue was created. We obtained the shapes and periods for five of our asteroids from their light-curves built with additional photometry taken from external archives. We demonstrated that our methodologies are robust and reliable approaches to find, at zero cost of observing time, asteroids observed by chance in astronomical surveys. Our future goal is to apply them to other surveys with adequate temporal coverage.

description: It is well known that any 4-dimensional hyperkahler metric with two commuting Killing fields may be obtained explicitly, via the Gibbons-Hawking Ansatz, from a harmonic function invariant under a Killing field on R^3. In this paper, we find all selfdual Einstein metrics of nonzero scalar curvature with two commuting Killing fields. They are given explicitly in terms of a local eigenfunction of the Laplacian on the hyperbolic plane. We discuss the relation of this construction to a class of selfdual spaces found by Joyce, and some Einstein-Weyl spaces found by Ward, and then show that certain `multipole' hyperbolic eigenfunctions yield explicit formulae for the quaternion-kahler quotients of HP(m-1) by an (m-2)-torus first studied by Galicki and Lawson. As a consequence we are able to place the well-known cohomogeneity one metrics, the quaternion-kahler quotients of HP(2) (and noncompact analogues), and the more recently studied selfdual Einstein hermitian metrics in a unified framework, and give new complete examples.

description: The microscopic structure of a charge stripe in an antiferromagnetic insulator is studied within the t-Jz model using analytical and numerical approaches. We demonstrate that a stripe in an antiferromagnet should be viewed as a system of composite holon-spin-polaron excitations condensed at the self-induced antiphase domain wall (ADW) of the antiferromagnetic spins. The properties of such excitations are studied in detail with numerical and analytical results for various quantities being in very close agreement. A picture of the stripe as an effective one-dimensional (1D) band of such excitations is also in very good agreement with numerical data. These results emphasize the primary role of kinetic energy in favoring the stripe as a ground state. A comparative analysis suggests the effect of pairing and collective meandering on the energetics of the stripe formation to be secondary. The implications of this microscopic picture of fermions bound to the 1D antiferromagnetic ADW for the effective theories of the stripe phase in the cuprates are discussed.

Transportation Economics: Some Developments Over the Past 30 Years

description: This paper looks at the changes that have occurred since the 1970s in the types of economic tools used, the ways they have been used, and the impacts they have had in shaping the way we now understand transportation. Over the past 30 years, society’s views on transport have changed and, with this, the issues to which we attach priority have altered. Additionally, there have been important changes in our more generic understanding of economics and this has added to the toolkit of concepts that can be applied to transport matters. The tradition of transportation economics up until the late 1960s was largely one of defining ‘optimal’ pricing principles in regulated markets, in understanding market domination for mergers and similar policies, and in providing advice to engineers dealing with investment decisions. There is now, however, an appreciation that providing transport services is more complex than was once thought and, therefore, it is better to leave as much as possible to market forces; but this has also happened at a time when our understanding of markets has changed. There has additionally been the emergence of novel political and governance structures, such as the Single European Market, that have resurrected older interests in such things as links between economic development and transport quality. Despite this shift to the market as a primary means of resource allocation, parallel moves have taken place to embrace more fully the external costs of environmental damage. The advent of computers, more sophisticated econometric and programming techniques, and the availability of new data sources, such as GIS, have facilitated more efficient estimation of parameters and added to the quantitative contribution of economics.

description: An inhomogeneous cosmological magnetic field creates vortical perturbations that survive Silk damping on much smaller scales than compressional modes. This ensures that there is no sharp cut-off in anisotropy on arc-minute scales. As we had pointed out earlier, tangled magnetic fields, if they exist, will then be a potentially important contributor to small-angular scale CMBR anisotropies. Several ongoing and new experiments, are expected to probe the very small angular scales, corresponding to multipoles with l>1000. In view of this observational focus, we revisit the predicted signals due to primordial tangled magnetic fields, for different spectra and different cosmological parameters. We also identify a new regime, where the photon mean-free path exceeds the scale of the perturbation, which dominates the predicted signal at very high l. A scale-invariant spectrum of tangled fields which redshifts to a present value B_{0}=3\times 10^{-9} Gauss, produces temperature anisotropies at the 10 micro Kelvin level between l ~ 1000-3000. Larger signals result if the univese is lambda dominated, if the baryon density is larger, or if the spectral index of magnetic tangles is steeper, n > -3. The signal will also have non-Gaussian statistics. We predict the distinctive form of the increased power expected in the microwave background at high l in the presence of significant tangled magnetic fields. We may be on the verge of detecting or ruling out the presence of tangled magnetic fields which are strong enough to influence the formation of large-scale structure in the Universe.

description: Spring load restrictions (SLR) regulate the weight per axle carried by heavy trucks during the spring thaw period. This policy aims to reduce pavement damage caused by heavy vehicles and extend the useful life of roads, but it also imposes costs on the trucking industry. A cost/benefit study, based on the results of surveys of industry costs, a pavement performance model, and a freight demand model, concludes that the benefits of lifting the existing SLR policy outweigh the additional costs. The cost of additional damage should be recovered from those who benefit from the change in policy.
