description: It has recently been shown that black holes can act as particle accelerators and two particles can collide with arbitrarily high center-of-mass (CM) energy under certain critical conditions. In this paper, we investigate particle collisions outside a Reissner-Nordström de Sitter (RN-dS) black hole. We find that infinite CM energy can be produced near the cosmological horizon for generic spacetime configurations. Remarkably, such infinite CM energy does not require the black hole to be extremal, in contrast to spacetimes in the absence of cosmological constants. However, since the charge of an astrophysical body is negligible, the required charge to mass ratio of the particle is extremely higher than that of any elementary particle.

description: Several energy spectra of cosmic rays with energies E_0 \geq 10^17 eV measured at the Yakutsk EAS, AGASA, Haverah Park, HiRes, Auger, and SUGAR arrays are considered. It is shown that the fairly good mutual agreement of the spectrum shapes can be achieved if the energy of each spectrum is multiplied by a factor K specific for each spectrum. These factors exhibit a pronounced dependence on the latitude of the above-mentioned arrays.

Rate Coefficients for D(1s) + H+ ⇆ D+ + H(1s) Charge Transfer and Some Astrophysical Implications

description: We have calculated the rate coefficients for D(1s) + H+ ⇆ D+ + H(1s) using recently published theoretical cross sections. We present results for temperatures T from 1 K up to 2 × 105 K and provide fits to our data for use in plasma modeling. Our calculations are in good agreement with previously published rate coefficients for 25 ≤ T ≤ 300 K, which covers most of the limited range for which those results were given. Our new rate coefficients for T ≳100 K are significantly larger than the values most commonly used for modeling the chemistry of the early universe and of molecular clouds. This may have important implications for the predicted HD abundance in these environments. Using our results, we have modeled the ionization balance in high-redshift QSO absorbers. We find that the new rate coefficients decrease the inferred D/H ratio by ≲0.4%. This is a factor of ≳25 smaller than the current ≳10% uncertainties in QSO absorber D/H measurements.

description: Magnitude is a numerical invariant of compact metric spaces. Its theory is most mature for spaces satisfying the classical condition of being of negative type, and the magnitude of such a space lies in the interval $[1, \infty]$. Until now, no example with magnitude $\infty$ was known. We construct some, thus answering a question open since 2010. We also give a sufficient condition for the magnitude of a space to converge to 1 as it is scaled down to a point, unifying and generalizing previously known conditions.

description: Includes bibliographical references.
description: In recent years scintillometry technology has become a recognized tool for the estimation of spatially-averaged vegetative ET rates. In particular, a Large Aperture Scintillometer (LAS) can provide estimates of the surface sensible heat flux (H) and, in combination with measurements of surface net radiation (Rn) and ground heat flux (G), can be used to solve for evaporative heat flux (λE) using the surface energy balance method. The LAS can operate over path lengths between 250 and 4500 m approximately and reports a path-averaged signal whose largest weight is at the path center. Two separate deployments of a Kipp and Zonen model LAS were considered; the first case (alfalfa deployment, site 1) during the 2010 summer over a fully irrigated alfalfa field and the second case (grassland deployment, site 2) at a dry grassland site during the 2011 summer. In each case, ancillary instrumentation was deployed for capturing necessary meteorological inputs and measurements of Rn and G. For the alfalfa deployment, a two-week subset of near-reference condition (50 cm crop height) data was processed and analyzed to derive hourly estimates of energy-balance ET from the LAS signal. The resulting H for this condition was generally less than 50 W m-2 during the morning/early afternoon periods, and negative H between 50-150 W m-2 was observed during the afternoon/evening periods, which suggests advective conditions. ET rates for the same data subset had a generally consistent daytime peak near 0.8 mm h-1. For the grassland deployment, hourly ET rates were derived from the LAS signal for a two-week subset of data following two significant precipitation events. Daytime peak hourly ET varied from approximately 0.6-0.7 mm h-1 following the precipitation events to approximately 0.3 mm h-1 at the end of the subset. Daytime peak H for the same period ranged from 150-300 W m-2.

Market Disruption, Export Market Disruption, Compensation, and GATT Reform
Creators: name: Bhagwati, Jagdish N.
Publisher: name: Columbia University
Year: 1976
Subjects: Economics

description: This paper analyzes the problem of market disruption as it currently afflicts the exporting countries, chiefly LDCs. Based on the analysis of optimal policy intervention under endogenous uncertainty, developed by Bhagwati and Srinivasan (Journal of International Economics, November 1976), it develops a complete set of rules by which the developed and less developed countries may abide, under a revised GATT code, when faced by the problem of increased competitiveness of LDC exports to DC markets. These rules include the compensation of LDCs by DCs, in varying degrees, for both potential and actual exercise of import restrictions by DCs.
Wind energy forecasting with missing values within a fully conditional specification framework

description: Wind power forecasting is essential to power system operation and electricity markets. As abundant data became available thanks to the deployment of measurement infrastructures and the democratization of meteorological modelling, extensive data-driven approaches have been developed within both point and probabilistic forecasting frameworks. These models usually assume that the dataset at hand is complete and overlook missing value issues that often occur in practice. In contrast to that common approach, we rigorously consider here the wind power forecasting problem in the presence of missing values, by jointly accommodating imputation and forecasting tasks. Our approach allows inferring the joint distribution of input features and target variables at the model estimation stage based on incomplete observations only. We place emphasis on a fully conditional specification method owing to its desirable properties, e.g., being assumption-free when it comes to these joint distributions. Then, at the operational forecasting stage, with available features at hand, one can issue forecasts by implicitly imputing all missing entries. The approach is applicable to both point and probabilistic forecasting, while yielding competitive forecast quality within both simulation and real-world case studies. It confirms that by using a powerful universal imputation method like fully conditional specification, the proposed approach is superior to the common approach, especially in the context of probabilistic forecasting.

description: We study parametric resonance of capillary waves on the interface between two immiscible Bose-Einstein condensates pushed towards each other by an oscillating force. Guided by analytical models, we solve numerically the coupled Gross-Pitaevskii equations for two-component Bose-Einstein condensate at zero temperature. We show that, at moderate amplitudes of the driving force, the instability is stabilized due to non-linear modifications of the oscillation frequency. When the amplitude of the driving force is large enough, we observe detachment of droplets from the Bose-Einstein condensates, resulting in generation of quantum vortices (skyrmions). We analytically investigate the vortex dynamics, and conditions of quantized vortex generation.

description: Euler-symmetric projective varieties, introduced by Baohua Fu and Jun-Muk Hwang in 2020, are nondegenerate projective varieties admitting many $\mathbb{C}^{\times}$-actions of Euler type. They are quasi-homogeneous and uniquely determined by their fundamental forms at a general point. In this paper, we study complete intersections in projective spaces which are Euler-symmetric. It is proven that such varieties are complete intersections of hyperquadrics and the base locus of the second fundamental form at a general point is again a complete intersection.

Heavy quark currents in ultra-high energy neutrino interactions

Year: 2011
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: We discuss heavy quark contributions to the neutrino-nucleon total cross section at very high energies, well above the real top production threshold. The top-bottom weak current is found to generate strong left-right asymmetry of neutrino-nucleon interactions. We separate contributions of different helicity states and make use of the $\bkappa$-factorization to derive simple and practically useful formulas for the left-handed ($F_L$) and right-handed ($F_R$) components of the conventional structure function $2xF_3=F_L-F_R$ in terms of the integrated gluon density. We show that $F_L\gg F_R$ and, consequently, $xF_3\approx F_T$, where $F_T$ is the transverse structure function. The conventional structure function $F_2=F_S+F_T$ at $Q^2\ll m_t^2$ appears to be dominated by its scalar (also known as longitudinal) component $F_S$ and the hierarchy $F_S\gg F_L\gg F_R$ arises naturally. We evaluate the total neutrino-nucleon cross section at ultra-high energies within the color dipole BFKL formalism.

description: We consider two random walks evolving synchronously on a random out-regular graph of $n$ vertices with bounded out-degree $r\ge 2$, also known as a random Deterministic Finite Automaton (DFA). We show that, with high probability with respect to the generation of the graph, the meeting time of the two walks is stochastically dominated by a geometric random variable of rate $(1+o(1))n^{-1}$, uniformly over their starting locations. Further, we prove that this upper bound is typically tight, i.e., it is also a lower bound when the locations of the two walks are selected uniformly at random. Our work takes inspiration from a recent conjecture by Fish and Reyzin in the context of computational learning, the connection with which is discussed.

description: In radar systems, tracking targets in low signal-to-noise ratio (SNR) environments is a very important task. There are some algorithms designed for multitarget tracking. Their performances, however, are not satisfactory in low SNR environments. Track-before-detect (TBD) algorithms have been developed as a class of improved methods for tracking in low SNR environments. However, multitarget TBD is still an open issue. In this paper, multitarget TBD measurements are modeled, and a highly efficient filter in the framework of finite set statistics (FISST) is designed. Then, the probability hypothesis density (PHD) filter is applied to multitarget TBD. Indeed, to solve the problem of the target and noise not being separated correctly when the SNR is low, a shrinkage-PHD filter is derived, and the optimal parameter for shrinkage operation is obtained by certain optimization procedures. Through simulation results, it is shown that our method can track targets with high accuracy by taking advantage of shrinkage operations.

description: Global climate change has brought significant changes in hydrological environment. Those changes also have occurred in the Korea peninsular for the last several decades, increasing the magnitude of damage by droughts and floods. As an attempt to explore the impact of droughts which may be made worse by the climate change, we analyze the change in the water balance of the Han-river basin. To accomplish it, we suggest a procedure consisting of three successive sub-procedures: daily rainfall generation for 90 years by the RegCM3 with the A2 scenario, daily discharge simulations by SLURP using the generated daily rainfall data, and monthly water balance analysis by K-WEAP (Korean Water Evaluation and Planning System) based on the SLURP simulation. Since significant uncertainty is involved in forecasting the future water consumption and water yields, we assumed three water consumption scenarios and three water yields scenarios. Three water consumption scenarios are, namely, "LOW", "MEDIUM", and "HIGH" according to the expected amount of water consumption. The fifty daily discharges are obtained from the SLURP simulations during the drought period. To improve the representability of possible daily rainfall events, fifty sets of daily rainfall data for 90 years are generated and then each set is used as an input for the SLURP simulation. Finally, water balance analysis is performed by K-WEAP based on 150 combinations from three water consumption scenarios and the fifty daily discharges. By these procedures, it is possible to explore various water consumption and water yield scenarios and the results of this study can be used to establish appropriate plans for minimizing the impact of drought resulted from the climate change in Korean peninsula.

description: An effective interaction approach is used to describe the interactions between the spin 0 or spin 1/2 dark matter particle and the degrees of freedom of the standard model. This approach is applicable to those models in which the dark matter particles do not experience the standard-model interactions, e.g., hidden-sector models. We explore the effects of these effective interaction operators on (i) dark matter relic density, (ii) spin-independent and spin-dependent dark matter-nucleon scattering cross sections, (iii) cosmic antiproton and gamma ray fluxes from the galactic halo due to dark matter annihilation, and (iv) monojet and monophoton production plus missing energy at the Tevatron and the Large Hadron Collider (LHC). We combine the experimental data of relic density from WMAP7, spin-independent cross section from XENON100, spin-dependent cross section from XENON10, ZEPLIN-III, and SIMPLE, cosmic antiproton flux from PAMELA, cosmic gamma-ray flux from ${\it Fermi}$-LAT, and the monojet and monophoton data from the Tevatron and the LHC, to put the most comprehensive limits on each effective operator.

description: We examine the utility of the quadratic pseudospectrum in photonics and condensed matter. Specifically, the quadratic pseudospectrum represents a method for approaching systems with incompatible observables, as it both minimizes the "eigen-error" in the joint approximate spectrum of the incompatible observables and does not increase the system's computational complexity. Moreover, we derive an important estimate relating the Clifford and quadratic pseudospectra. Finally, we prove that the quadratic pseudospectrum is local, and derive the bounds on the errors that are incurred by truncating the system in the vicinity of where the pseudospectrum is being calculated.

description: Galactic Archeology is a powerful tool for investigating the formation and evolution of the Milky Way. We use this technique to study kinematic groups of F- and G-stars in the solar neighbourhood. From correlations between orbital parameters, three new coherent groups of stars were recently identified and suggested to correspond to remnants of disrupted satellites. We determine detailed elemental abundances in stars belonging to one of these groups and compare their chemical composition with Galactic disc stars. The aim is to look for possible chemical signatures that might give information about the history of this kinematic group of stars. High-resolution spectra were obtained with the FIES spectrograph at the Nordic Optical Telescope, La Palma, and analysed with a differential model atmosphere method. Comparison stars were observed and analysed with the same method. The average value of [Fe/H] for the 20 stars investigated in this study is -0.69 +- 0.05 dex. Elemental abundances of oxygen and alpha-elements are overabundant in comparison with Galactic thin-disc dwarfs and thin-disc chemical evolution models. This abundance pattern has similar characteristics as the Galactic thick-disc. The homogeneous chemical composition together with the kinematic properties and ages of stars in the investigated Group 3 of the Geneva-Copenhagen survey provides evidence of their common origin and possible relation to an ancient merging event. The similar chemical composition of stars in the investigated group and the thick-disc stars might suggest that their formation histories are linked.

description: Surface barriers, constructed of earthen materials, are a viable option for long-term management of contaminated sites within arid and semi-arid environments. Design and licensing of surface barriers will require a demonstrated understanding of the multidimensional nonisothermal geohydrologic and coupled ground surface to atmosphere water mass and energy transport processes that control water infiltration to the subsurface. A prototype barrier on a shrug-steppe site at Hanford has been monitored since 1994, providing vegetation and water balance data that includes drainage from the sideslopes. As a prelude to inverse numerical modeling to estimate critical parameters for the prototype barrier, this paper describes and demonstrates a numerical simulator for modeling the prototype barrier in shrub-steppe environments. The numerical simulator comprises a three-dimensional nonisothermal multifluid subsurface flow and transport simulator fully coupled to a modified nonlinear sparsely vegetated (are substrate to closed canopy) evapotranspiration module that mechanistically predicts evaporation.

Capital Market Liberalization and Exchange Rate Regimes: Risk without Reward
Creators: name: Stiglitz, Joseph E.
Publisher: name: Columbia University
Year: 2002
Subjects: Economics

description: This paper examines the consequences of capital market liberalization, with special reference to its effects under different exchange rate regimes. Capital market liberalization has not lead to faster growth in developing countries, but has led to greater risks. It describes how International Monetary Fund policies have exacerbated the risks, as a result of the macro-economic response to crises, with bail-out packages that have intensified moral hazard problems. The paper provides a critique of the arguments for capital market liberalization. It argues that capital flows give rise to large externalities, which affect others than the borrower and lender, and whenever there are large externalities, there is potential scope for government interventions, some of which are welfare increasing.
Coping with Antiglobalization
Creators: name: Bhagwati, Jagdish N.
Publisher: name: Columbia University
Year: 2002
Subjects: Economics

description: This article discusses the anti-globalization movement and how attitudes of anti-capitalism among young people are helping to fuel the movement. This younger group of critics has found three common grounds of discontent with globalization--the idea of capitalism, the process of globalization, and the behavior of corporations--and have made their views clear at recent protests in the streets at world economic gatherings and on college campuses. Many of these youthful skeptics see capitalism as a system that cannot significantly address issues of social justice. The author discusses various influences on college students including the Deconstructionist theory of Jacques Derrida, the topic of anarchy and theories taught within sociology, and the use of the Internet in spreading anti-capitalist attitudes.

description: We have used kinetic Monte Carlo (kMC) simulations of a lattice gas to study front fluctuations in the spreading of a non-volatile liquid droplet onto a solid substrate. Our results are consistent with a diffusive growth law for the radius of the precursor layer, $R \sim t^δ$, with $δ\approx 1/2$ in all the conditions considered for temperature and substrate wettability, in good agreement with previous studies. The fluctuations of the front exhibit kinetic roughening properties with exponent values which depend on temperature $T$, but become $T$-independent for sufficiently high $T$. Moreover, strong evidences of intrinsic anomalous scaling have been found, characterized by different values of the roughness exponent at short and large length scales. Although such a behavior differs from the scaling properties of the one-dimensional Kardar-Parisi-Zhang (KPZ) universality class, the front covariance and the probability distribution function of front fluctuations found in our kMC simulations do display KPZ behavior, agreeing with simulations of a continuum height equation proposed in this context. However, this equation does not feature intrinsic anomalous scaling, at variance with the discrete model.

description: We have examined the ratio between the integrated luminosity of massive young stellar objects detected by the Red MSX Source (RMS) survey and the mass of molecular clouds in the Galactic Ring Survey region, as a function of Galactocentric radius. The results indicate that 60--80% of the observed increases in the star-formation rate density associated with spiral-arm features are due to source crowding within the arms. Of the remainder, most of the increase in the inner Sagittarius arm is due to an enhancement in the simple star-formation efficiency, i.e. in the number of RMS sources per unit molecular gas mass. In the inner Perseus arm, the residual increase is due to a higher than average mean source luminosity, which implies a top-heavy IMF, and this is entirely due to the presence, in the GRS region, of the W49 star-forming complex, which appears to be exceptional in its nature. The results also suggest that there is little or no increase in the star-formation efficiency on kiloparsec scales in the Scutum tangent region which includes W43. We discuss the possible role played by the spiral arms in influencing the star-formation efficiency and conclude that the most likely mechanisms are related to orbit crowding within the arms.

description: Canada is one of the most ethnically diverse countries in the world, and thus issues relating to integration of immigrants into Canada are increasingly important to understand, since they have diverse material consequences for immigration policies, successful transitions for persons coming to Canada, and ethno-cultural identities. The goal of this research is use an Australian model developed by Nesdale and Mak (2000) to expand our knowledge of what factors are important to the development of a sense of belonging to a host country, focusing on Canada. It builds on previous Canadian research by using a more comprehensive dependent variable and includes representatives of all ethnic groups immigrating to Canada. The results indicate that factors including ethnic identification, acculturation attitudes, demographic variables (age, gender, education), and acceptance by the host society are all important to developing a sense of belonging to a host country, whereas unexpectedly, indicators of material success are not.

description: The seasonal snowpack in Rocky Mountain National Park is critical to the local and downstream water supply and the ecosystem of the park, and is important for winter recreational opportunities. Recent regional studies of trends in observed snow water equivalent (SWE) over the past three and a half decades have illustrated that temperatures are rising. Snow accumulation is decreasing, averaging on the order of a 2 to 4 cm/decade decline with snowmelt tending to be earlier, averaging on the order of 2 to 4 days/decade sooner. To place these SWE trends observed over the past few decades into a longer-term context, multi-century SWE reconstructions were derived from tree-ring widths and examined to determine whether similar multi-decade trends have occurred in the past. Possible SWE trends were examined into the future using projections from the Coupled Model Inter-comparison Project-Phase 5 (CMIP5) climate models linked to hydrologic models to identify models that best fit the observed data. From these model projections, possible SWE trends were estimated for the remainder of the 21st century. Results of the paleo-analysis suggest that similar multi-decade declining trends in SWE have occurred in the study area at certain times over the past four centuries. Results of the model projections suggest that recently observed trends (past 3+ decades) are likely to continue over the next eight or so decades.

description: All near horizon geometries of supersymmetric black holes in a N=2, D=5 higher-derivative supergravity theory are classified. Depending on the choice of near-horizon data we find that either there are no regular horizons, or horizons exist and the spatial cross-sections of the event horizons are conformal to a squashed or round S^3, S^1 * S^2, or T^3. If the conformal factor is constant then the solutions are maximally supersymmetric. If the conformal factor is not constant, we find that it satisfies a non-linear vortex equation, and the horizon may admit scalar hair.
