description: Let W -> A^2 be the universal Weierstrass family of cubic curves over C. For each N >= 2, we construct surfaces parametrizing the three standard kinds of level N structures on the smooth fibers of W. We then complete these surfaces to finite covers of A^2. Since W -> A^2 is the versal deformation space of a cusp singularity, these surfaces convey information about the level structure on any family of curves of genus g degenerating to a cuspidal curve. Our goal in this note is to determine for which values of N these surfaces are smooth over (0,0). From a topological perspective, the results determine the homeomorphism type of certain branched covers of S^3 with monodromy in SL_2(Z/N).

subject: FOS: Physical sciences

description: Standard formulae of classical electromagnetism for the forces between electric charges in motion derived from retarded potentials are compared with those obtained from a recently developed relativistic classical electrodynamic theory with an instantaneous inter-charge force. Problems discussed include small angle Rutherford scattering, Jackson's recent `torque paradox' and circular Keplerian orbits. Results consistent with special relativity are obtained only with an instantaneous interaction. The impossiblity of stable circular motion with retarded fields in either classical electromagnetism or Newtonian gravitation is demonstrated.

description: Systems with strong spin-orbit coupling have been a topic of fundamental interest in condensed matter physics due to the exotic topological phases and the unconventional phenomenon they exhibit. In this particular study, we have investigated the superconductivity in the transition-metal ternary noncentrosymmetric compounds LaMSi (M = Ni, Pt) with different spin-orbit coupling strength, using muon-spin rotation and relaxation measurements. Transverse-field measurements made in the vortex state indicate that the superconductivity in both materials is fully gapped, with a conventional s-wave pairing symmetry and BCS-like magnitudes for the zero-temperature gap energies. Zero field measurements suggest a time-reversal symmetry preserved superconductivity in both the systems, though a small increase in muon depolarization is observed upon decreasing temperature. However, this has been attributed to quasi-static magnetic fluctuations.

description: The investigation of pulsars between millimetre and optical wavelengths is challenging due to the faintness of the pulsar signals and the relative low sensitivity of the available facilities compared to 100-m class telescopes operating in the centimetre band. The Kinetic Inductance Detector (KID) technology offers large instantaneous bandwidths and a high sensitivity that can help to substantially increase the ability of existing observatories at short wavelengths to detect pulsars and transient emission. To investigate the feasibility of detecting pulsars with KIDs, we observed the anomalous X-ray pulsar XTE J1810-197 with the New IRAM KIDs Array-2 (NIKA2) camera installed at the IRAM 30-m Telescope in Spain. We detected the pulsations from the pulsar with NIKA2 at its two operating frequency bands, 150 and 260 GHz ($λ$=2.0 and 1.15 mm, respectively). This is the first time that a pulsar is detected with a receiver based on KID technology in the millimetre band. In addition, this is the first report of short millimetre emission from XTE J1810-197 after its reactivation in December 2018, and it is the first time that the source is detected at 260 GHz, which gives us new insights into the radio emission process of the star.

Rotation periods for stars of the TW Hydrae association
Creators: name: Lawson, Warrick A.

Year: 2005
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: We have conducted a photometric study of late-type members of the TW Hydrae association (TWA) and measured the rotation periods for 16 stars in 12 systems. For TWA stars listed by Webb et al. and Sterzik et al. (TWA 1-13; led by TW Hya = TWA 1) we find a median period of 4.7 d. However, for stars that we measured in the TWA 14-19 group identified by Zuckerman et al., we find a median period of only 0.7 d. The period distributions of the two groups cannot be reconciled at the 3-sigma significance level. Using photometric arguments supported by the Hipparcos distance to HD 102458 (= TWA 19A), we find that TWA 14-19 reside at an average distance of d \approx 90 pc, spatially at the near boundary of the Lower Centaurus-Crux (LCC) subgroup of the Ophiuchus-Scorpius-Centaurus OB-star association (OSCA). Proper motions for HD 102458, TWA 14, 18 and 19B link these stars to the LCC subgroup. From Hertzsprung-Russell (H-R) diagram placement, we derive an age of \approx 17 Myr for the HD 102458 system that may be the representative age for the TWA 14-19 group. Merging various lines of evidence, we conclude that these stars form a spatially- and rotationally-distinct population of older pre-main sequence (PMS) stars, rather than being an extension of the TWA beyond those stars associated with TW Hya that have an age of \sim 10 Myr and reside at d \approx 55 pc. Instead, TWA 14-19 likely represent the population of low-mass stars still physically associated with the LCC subgroup.

description: The characteristics of intermediate mass fragments (IMFs: 3<=Z<=20) produced in mid-peripheral and central collisions are compared. We compare IMFs detected at mid-velocity with those evaporated from the excited projectile-like fragment (PLF*). On average, the IMFs produced at mid-velocity are larger in atomic number, exhibit broader transverse velocity distributions, and are more neutron-rich as compared to IMFs evaporated from the PLF*. In contrast, comparison of mid-velocity fragments associated with mid-peripheral and central collisions reveals that their characteristics are remarkably similar despite the difference in impact parameter. The characteristics of mid-velocity fragments are consistent with low-density formation of the fragments. Neutron deficient isotopes of even Z elements manifest higher kinetic energies than heavier isotopes of the same element for both PLF* and mid-velocity emission. This result may be due to the decay of long-lived excited states in the field of the emitting system.

description: Three-body continuum states are investigated with the hyperspherical method on a Lagrange mesh. The $R$-matrix theory is used to treat the asymptotic behaviour of scattering wave functions. The formalism is developed for neutral as well as for charged systems. We point out some specificities of continuum states in the hyperspherical method. The collision matrix can be determined with a good accuracy by using propagation techniques. The method is applied to the $^6$He (=$α$+n+n) and $^6$Be (=$α$+p+p) systems, as well as to $^{14}$Be (=$^{12}$Be+n+n). For $^6$He, we essentially recover results of the literature. Application to $^{14}$Be suggests the existence of an excited $2^+$ state below threshold. The calculated B(E2) value should make this state observable with Coulomb excitation experiments.

The Science of $ΘΔ^{cs}$

Subjects: subject: History and Philosophy of Physics (physics.hist-ph)
subject: FOS: Physical sciences

description: There is a long tradition of thinking of thermodynamics, not as a theory of fundamental physics (or even a candidate theory of fundamental physics), but as a theory of how manipulations of a physical system may be used to obtain desired effects, such as mechanical work. On this view, the basic concepts of thermodynamics, heat and work, and with them, the concept of entropy, are relative to a class of envisaged manipulations. This view has been dismissed by many philosophers of physics, in my opinion too hastily. This paper is a sketch and defense of a science of manipulations and their effects on physical systems. This is, I claim, the best way to make sense of thermodynamics as it is found in textbooks and as it is practiced. I call this science thermo-dynamics (with hyphen), or $ΘΔ^{cs}$, for short, to highlight that it may be different from the science of thermodynamics, as the reader conceives it. Even if one is not convinced that it is the best way to make sense of thermodynamics as it is practiced, it should be non-controversial that $ΘΔ^{cs}$ is a legitimate science. An upshot of the discussion is a clarification of the roles of the Gibbs and von Neumann entropies. Given the definition of statistical thermo-dynamic entropy, it can be proven that, under the assumption of availability of thermodynamically reversible processes, these functions are the unique (up to an additive constant) functions that represent thermo-dynamic entropy. Light is also shed on the use of coarse-grained entropies.}
A clique tree algorithm exploiting context specific independence
Creators: name: Tung, Leslie
Publisher: name: University of British Columbia
Year: 2009

description: Context specific independence can provide compact representation of the conditional probabilities in Bayesian networks when some variables are only relevant in specific contexts. We present eve-tree, an algorithm that exploits context specific independence in clique tree propagation. This algorithm is based on a query-based contextual variable elimination algorithm (eve) that eliminates in turn the variables not needed in an answer. We extend eve to producing the posterior probabilities of all variables efficiently and allow the incremental addition of evidence. We perform experiments that compare eve-tree and Hugin using parameterized random networks that exhibit various amounts of context specific independence, as well as a standard network, the Insurance network. Our empirical results show that eve-tree is efficient, both in time and in space, as compared to the Hugin architecture, on computing posterior probabilities for Bayesian networks that exhibit context specific independence.

Exploring strategic motives behind cost and time overruns in oil and gas infrastructure projects

description: Problems most frequently discussed in the regard of cost and time overruns in project management literature are planning failures, such as understated budgets, underrepresented technical complexity, and issues with public approval. Less frequent are discussions of changes in project scope and technical complexity related changes in market, industry, and policy environments. Most examples of impacts of market conditions on decision making prior to final investment decision (FID) are found, while little focus is found on how projects underway are impacted and dealt with. This thesis study will contribute to that latter strand of literature and explore how changes in project timeline and technical specifications can be interrelated to changes in market and policy parameters and therewith, may be justified from a project economics standpoint. To be specific, the study will focus the situation of significant drop in oil prices and natural gas prices and fast changing environmental regulations since 2014. On one hand, decreasing capital spending by oil and gas upstream companies led to decrease in supply. On the other hand, the prices of equipment are falling. Midstream companies may decide to increase the construction time of their projects to enjoy lower equipment costs, and to have the start of their project be associated with the return of higher oil and gas prices and therewith increased demand for newly-installed capacities which would warrant higher profits. This thesis performed decision tree analysis and net present value (NPV) calculation for a post-FID mid-construction pipeline infrastructure project to understand whether cost and time overruns may have potentially positive value from a theoretical and practical perspective. In particular, the study proposes how making decision changes to project timelines and specifications at that stage can alter the economic viability of the projects and give them a better chance at avoiding economic failure despite the overruns. This thesis will provide a decision-making method for project managers and contractors for situations where unexpected drastic changes in market conditions might affect the success for a mid-construction project. It will seek to provide information to potential investors and FID makers about the fate of similar projects.

description: Magnetic reconnection plays a crucial role in powering solar flares, production of energetic particles, and plasma heating. However, where the magnetic reconnections occur, how and where the released magnetic energy is transported, and how it is converted to other forms remain unclear. Here we report recurring bi-directional plasma outflows located within a large-scale plasma sheet observed in extreme ultraviolet emission and scattered white light during the post-impulsive gradual phase of the X8.2 solar flare on 2017 September 10. Each of the bi-directional outflows originates in the plasma sheet from a discrete site, identified as a magnetic reconnection site. These reconnection sites reside at very low altitudes ($< 180$ Mm, or 0.26 $R_{\odot}$) above the top of the flare arcade, a distance only $<3\%$ of the total length of a plasma sheet that extends to at least 10 $R_{\odot}$. Each arrival of sunward outflows at the looptop region appears to coincide with an impulsive microwave and X-ray burst dominated by a hot source (10-20 MK) at the looptop, which is immediately followed by a nonthermal microwave burst located in the loopleg region. We propose that the reconnection outflows transport the magnetic energy released at localized magnetic reconnection sites outward in the form of kinetic energy flux and/or electromagnetic Poynting flux. The sunward-directed energy flux induces particle acceleration and plasma heating in the post-flare arcades, observed as the hot and nonthermal flare emissions.

description: New uvby-βdata are provided for 442 high-velocity and metal-poor stars; 90 of these stars have been observed previously by us, and 352 are new. When combined with our previous two photometric catalogues, the data base is now made up of 1533 high-velocity and metal-poor stars, all with uvby-βphotometry and complete kinematic data, such as proper motions and radial velocities taken from the literature. Hipparcos, plus a new photometric calibration for M_v also based on the Hipparcos parallaxes, provide distances for nearly all of these stars; our previous photometric calibrations give values for E(b-y) and [Fe/H]. The [Fe/H],V(rot) diagram allows us to separate these stars into different Galactic stellar population groups, such as old-thin-disk, thick-disk, and halo. The X histogram, where X is our stellar-population discriminator combining V(rot) and [Fe/H], and contour plots for the [Fe/H],V(rot) diagram both indicate two probable components to the thick disk. These population groups and Galactic components are studied in the (b-y)_o,M_v diagram, compared to the isochrones of Bergbusch & VandenBerg (2001), to derive stellar ages. The two thick-disk groups have the mean characteristics: ([Fe/H], V(rot), Age, σ_W') ~ (-0.7 dex, 120 km/s, 12.5 Gyr, 62.0 km/s), and ~(-0.4, 160, 10.0, 45.8). The seven most metal-poor halo groups, -2.31 <= [Fe/H] <= -1.31, show a mean age of 13.0 +/-0.2 (mean error) Gyr, giving a mean difference from the WMAP results for the age of the Universe of 0.7 +/- 0.3 Gyr. These results for the ages and components of the thick disk and for the age of the Galactic halo field stars are discussed in terms of various models and ideas for the formation of galaxies and their stellar populations.

description: The study of planet occurrence as a function of stellar mass is important for a better understanding of planet formation. Estimating stellar mass, especially in the red giant regime, is difficult. In particular, stellar masses of a sample of evolved planet-hosting stars based on spectroscopy and grid-based modelling have been put to question over the past decade with claims they were overestimated. Although efforts have been made in the past to reconcile this dispute using asteroseismology, results were inconclusive. In an attempt to resolve this controversy, we study four more evolved planet-hosting stars in this paper using asteroseismology, and we revisit previous results to make an informed study of the whole ensemble in a self-consistent way. For the four new stars, we measure their masses by locating their characteristic oscillation frequency, $\mathrmν_{\mathrm{max}}$, from their radial velocity time series observed by SONG. For two stars, we are also able to measure the large frequency separation, $\mathrm{Δν}$, helped by extended SONG single-site and dual-site observations and new TESS observations. We establish the robustness of the $\mathrmν_{\mathrm{max}}$-only-based results by determining the stellar mass from $\mathrm{Δν}$, and from both $\mathrm{Δν}$ and $\mathrmν_{\mathrm{max}}$. We then compare the seismic masses of the full ensemble of 16 stars with the spectroscopic masses from three different literature sources. We find an offset between the seismic and spectroscopic mass scales that is mass-dependent, suggesting that the previously claimed overestimation of spectroscopic masses only affects stars more massive than about 1.6 M$_\mathrm{\odot}$.

description: Higher property taxes and uncertainty about post-easement tax levels may create a disincentive for landowners to participate in federal easement programs such as the Wetlands Reserve Program, and thus may distort participation levels in a manner inconsistent with the environmental benefits associated with individual parcels. Support for this hypothesis is provided in an exploratory analysis of state level participation in the Wetlands Reserve Program. If such distortions prove to be policy relevant, then either they should be accounted for in the bid acceptance process of future federal easement programs, or individual states and localities should correct property tax differentials and post-easement tax uncertainty.

description: We have studied the photoexcited carrier relaxation dynamics in the Kondo insulator SmB6 and the heavy fermion metal YbAgCu4 as a function of temperature and excitation level. The dynamic response is found to be both strongly temperature dependent and nonlinear. The data are analyzed with a Rothwarf-Taylor bottleneck model, where the dynamics are governed by the presence of a narrow gap in the density of states near the Fermi level. The remarkable agreement with the model suggests that carrier relaxation in a broad class of heavy electron systems (both metals and insulators) is governed by the presence of a (weakly temperature dependent) hybridization gap.

description: An indirect utility model is employed for measuring farmers' willingness to voluntarily accept yield losses for a reduction in environmental risk by decreasing pesticide use. Results support the hypothesis that farmers have self-described risk perceptions that enable them to make assessments of risk-yield tradeoffs. Policies designed to encourage and assist farmers making voluntary pesticide reductions can result in environmental risk reduction.

description: This paper studies the preferences and willingness-to-pay for individuals for volunteer water quality monitoring programs. The study involves supporting water quality monitoring at two ponds in the state of Rhode Island. The paper uses both a hypothetical and a real-payment contingent valuation survey to directly measure individual preferences and willingness-to-pay (WTP) for volunteer water quality monitoring at the two ponds. The overall results of the study suggest that hypothetical WTP is not statistically greater than real WTP, and that the average survey respondent is willing to support water quality monitoring on one of the two ponds. The study also finds that the specified purpose of water quality monitoring and certain socioeconomic characteristics of a respondent significantly affect the respondent's decision to support volunteer water quality monitoring.

description: Reducing costs of controlling nonpoint source (NPS) pollution will be a high public priority in the next century. Compliance and transaction costs of reducing nitrogen runoff from dairies in the Lower Susquehanna Watershed by 40% are estimated for perfectly targeted and uniform performance standards. The perfectly targeted standard reduces compliance and transaction costs by almost 75% compared with the uniform standard. Future NPS control policies should use spatial information to target policy resources to priority concerns, areas, and farms. Further research is needed to lower the costs and increase the accuracy of spatial information.

description: We propose an N=4 supersymmetric quantum mechanics of a charged particle on a sphere in the background of Dirac magnetic monopole and study the system using the CP(1) model approach. We explicitly calculate the symmetry algebra taking the operator ordering ambiguity into consideration. We find that it is given by the superalgebra SU(1|2)x SU(2). We show that the Hamiltonian can be written in terms of the Casimir invariant of SU(2). Using this relation and the lower bound for angular momentm we obtain the energy spectrum. We then examine the ground energy sector to find that the N=4 supersymmetry is spontaneously broken to N=2 for certain values of the monopole charge.

description: Gamma-ray burst light curves show quite different patterns: from very simple to extremely complex. We present a temporal and spectral study of the light curves in three energy bands (2-5, 5-10, 10-26 keV) of ten GRBs detected by the Wide Field Cameras on board BeppoSAX. For some events the time profiles are characterized by peaks superposed on a slowly evolving pedestal, which in some cases becomes less apparent at higher energies. We describe this behaviour with the presence of two components (slow and fast) having different variability time scales. We modelled the time evolution of slow components by means of an analytical function able to describe asymmetric rising and decaying profiles. The residual light curves, after the subtraction of the slow components, generally show structures more similar to the original curves in the highest energy band. Spectral study of these two components was performed evaluating their hardness ratios, used also to derive photon indices. Slow components are found generally softer than the fast ones suggesting that their origin is likely different. Being typical photon indices lower than those of the afterglows there is no evidence that the emission processes are similar. Another interesting possibility is that slow components can be related to the presence of a hot photosphere having a thermal spectrum with kT around a few keV superposed to a rapid variable non-thermal emission of the fast component.

Soft Hydraulics in Channels with Thick Walls: The Finite-Reynolds-Number Base State and Its Stability

description: We analyze the linear stability of the base state of the problem of coupled flow and deformation in a long and shallow rectangular soft hydraulic conduit with a thick top wall. Specifically, the steady base state is computed at low but finite Reynolds number. Then, we show that with the upstream flux fixed and the outlet pressure set to gauge, the flow is linearly stable to infinitesimal flow-wise perturbations. Multiple oscillatory but stable eigenmodes are computed in a range of the reduced Reynolds number, $\hat{Re}$, and the so-called fluid--structure interaction (FSI) parameter, $λ$, indicating the stiffness of this FSI system. These results provide a framework to address, in future work, the individual effects of various aspects of two-way FSI coupling on instability and flow transition in soft hydraulic conduits.

description: The role of land values in the dairy industry of an urban-influenced region is investigated by estimating a dairy herd equation based on pooled cross-section and time-series data from counties in New Jersey, Pennsylvania, and New York. The use of cross-terms between hypothesized causal variables and a dummy variable capturing the effect of location allowed the estimation of the differences across states in the effects of milk, feed, and land prices. Results confirm the important role of rising land values in the decline of the dairy industry in the tri-state area, and suggest greater vulnerability of dairy enterprises in urban-influenced areas to rising adverse economic forces. The adverse effects of declining milk prices and higher land values are greatest in New Jersey. The results support the notion that programs such as price support, farmland preservation, farmland assessment, and right-to-farm may have to be maintained in order to retain dairy farms at the urban fringe, where land values are rising rapidly.

description: This paper examines the impact of pesticide regulation on the number of new pesticide registrations and pesticide toxicity. Results suggest that regulation adversely affects new pesticide introductions but encourages the development of pesticides with fewer toxic side effects. The estimated regression model implies that a 10% increase in regulatory costs (about $1.5 million per pesticide) causes a 5% reduction in the number of pesticides with higher toxicity.

Photometric biases due to stellar blending: implications for measuring distances, constraining binarity and detecting exoplanetary transits

description: We investigate blending, binarity and photometric biases in crowded-field CCD imaging. For this, we consider random blend losses, which correspond to the total number of stars left undetected in unresolved blends. We present a simple formula to estimate blend losses, which can be converted to apparent magnitude biases using the luminosity function of the analyzed sample. Because of the used assumptions, our results give lower limits of the total bias and we show that in some cases even these limits point toward significant limitations in measuring apparent brightnesses of ``standard candle'' stars, thus distances to nearby galaxies. A special application is presented for the OGLE-II BVI maps of the Large Magellanic Cloud. We find a previously neglected systematic bias up to 0.2-0.3 mag for faint stars (V~18.0-19.0) in the OGLE-II sample, which affects LMC distance measurements using RR Lyrae and red clump stars. We also consider the effects of intrinsic stellar correlations, i.e. binarity, via calculating two-point correlation functions for stellar fields around seven recently exploded classical novae. In two cases, for V1494 Aql and V705 Cas, the reported close optical companions seem to be physically correlated with the cataclysmic systems. Finally, we find significant blend frequencies up to 50-60% in the samples of wide-field exoplanetary surveys, which suggests that blending calculations are highly advisable to be included into the regular reduction procedure.
