description: X-ray observations of shocked gas in novae can provide a useful probe of the dynamics of the ejecta. Here we report on X-ray observations of the nova V959 Mon, which was also detected in GeV gamma-rays with the Fermi satellite. We find that the X-ray spectra are consistent with a two-temperature plasma model with non-solar abundances. We interpret the X-rays as due to shock interaction between the slow equatorial torus and the fast polar outflow that were inferred from radio observations of V959 Mon. We further propose that the hotter component, responsible for most of the flux, is from the reverse shock driven into the fast outflow. We find a systematic drop in the column density of the absorber between Days 60 and 140, consistent with the expectations for such a picture. We present intriguing evidence for a delay of around 40 days in the expulsion of the ejecta from the central binary. Moreover, we infer a relatively small (a few times 10$^{-6}$ Msun) ejecta mass ahead of the shock, considerably lower than the mass of 10$^4$ K gas inferred from radio observations. Finally, we infer that the dominant X-ray shock was likely not radiative at the time of our observations, and that the shock power was considerably higher than the observed X-ray luminosity. It is unclear why high X-ray luminosity, closer to the inferred shock power, is never seen in novae at early times, when the shock is expected to have high enough density to be radiative.

description: We give a new approach to intersection theory. Our "cycles" are closed manifolds mapping into compact manifolds and our "intersections" are elements of a homotopy group of a certain Thom space. The results are then applied in various contexts, including fixed point, linking and disjunction problems. Our main theorems resemble those of Hatcher and Quinn, but our proofs are fundamentally different.

description: We study a model for a two-mode atomic-molecular Bose--Einstein condensate. Starting with a classical analysis we determine the phase space fixed points of the system. It is found that bifurcations of the fixed points naturally separate the coupling parameter space into four regions. The different regions give rise to qualitatively different dynamics. We then show that this classification holds true for the quantum dynamics.

description: This report presents the preliminary results of a statistically valid 2006 survey of small agricultural producers (sales of less than $50,000) in three Western states (Wyoming, Colorado and Arizona). The West has undergone significant change, and the composition of farm managers has changed with it. This report provides information from farm operators in the rural West on their perceived threats as well as characteristics of themselves and their operations. Topics of interest were demographics, reasons for involvement in agriculture, income, resource management (crops and livestock), and preferences for information delivery. The project was supported by the Western Center for Risk Management Education.

description: Fiber imaging bundles are widely used as thin, passive image conduits for miniaturised and endoscopic microscopy, particularly for confocal fluorescence imaging. Holographic microscopy through fiber bundles is more challenging; phase conjugation approaches are complex and require extensive calibration. This articles describes how simple inline holographic microscopy can be performed through an imaging bundle using a partially coherent illumination source from a multimode fiber. The sample is imaged in transmission, with the intensity hologram sampled by the bundle and transmitted to a remote camera. The hologram can then be numerically refocused for volumetric imaging, achieving a resolution of approximately 6 um over a depth range of 1 mm. The scheme does not require any complex prior calibration and hence is insensitive to bending.

Investigating the pion source function in heavy-ion collisions with the EPOS model

description: By measuring the momentum correlations of pions created in heavy-ion collisions we can gain information about the space-time geometry of the particle emitting source. Recent experimental results from multiple different collaborations demonstrated that to properly describe the shape of the measured correlation functions, one needs to go beyond the Gaussian approximation. Some studies suggest that the Levy distribution could provide a good description of the source. While there are already many experimental results, there is very little input from the phenomenology side in explanation of the observed non-Gaussian source shapes. The EPOS model is a sophisticated hybrid model where the evolution of the newly-created system is governed by Parton-Based Gribov-Regge theory. It has already proved to be successful in describing many different experimental observations for the systems characterized by baryon chemical potential close to zero, but so far the source shape has not been explored in detail. In this paper we discuss studies of the pion emitting source based on the theoretical approach of the EPOS model.

description: Very deep near-infrared observations have recently uncovered a significant population of red galaxies at redshifts z>2. These distant red galaxies (DRGs) are efficiently selected by the criterion J-K>2.3. We use Chandra data to examine the X-ray emission from DRGs in the 5'x5' FIRES MS1054-03 field. Two of 40 DRGs with K<22 are detected by Chandra, and we infer that ~5 % of DRGs host active nuclei with L>1.2x10^43 ergs/s. This fraction is smaller than that inferred from optical and near-IR spectroscopy, probably largely due to strong spectroscopic selection biases. By stacking all undetected DRGs we find that their average X-ray flux in the 0.5-8 keV band is ~4.6x10^-17 ergs/s/cm^2. The detection is only significant in the soft and full energy bands. The mean detection may result from star formation, the presence of low luminosity AGN, or a combination of both. Assuming the detection is due exclusively to star formation, we find an average instantaneous star formation rate of 214 +- 68 (random) +- 73 (systematic) solar masses per year, in excellent agreement with previous results from spectral energy distribution fitting when constant star formation histories are assumed. These results may imply that DRGs contribute significantly to the cosmic star formation rate at z~2.5. However, the mean X-ray flux strictly provides only an upper limit to the star formation rate due to the uncertain contribution of low luminosity, possibly obscured AGNs. Observations at other wavelengths are needed to provide independent estimates of the star formation rate of DRGs.

description: Agricultural water is a preferred source for meeting growing demands, but permanent transfers often require formerly irrigated land to be fallowed, removing a key industry from the regional economy. One alternative allows farmers to lease water to cities by fallowing their land on a rotational basis or limiting irrigation to reduce the consumptive use of their cropping operations. A survey of irrigators in Colorado’s South Platte Basin examines the remuneration needed for a farmer to enter into a lease agreement; the amount of water the farmer will release; the provisions desired in a lease agreement; and the characteristics shared by farmers who are willing to lease.

description: We have carried out magnetization, heat capacity, electrical and magnetoresistance measurements (2-300 K) for the polycrystalline form of intermetallic compounds, R2RhSi3 (R= Gd, Tb, and Dy), forming in a AlB2 derived hexagonal structure with a triangular R network. This work was primarily motivated by a revival of interest on Gd2PdSi3 after about two decades in the field of Toplogical Hall Effect due to magnetic skyrmions. We report here that these compounds are characterized by double antiferromagnetic transitions (T_N= 13.5 and 12 K for Gd, 13.5 and 6.5 K for Tb; 6.5 and 2.5 for Dy), but antiferromagnerism seems to be complex. The most notable observations common to all these compounds are: (i) There are many features in the data mimicking those seen for Gd2PdSi3, including the two field-induced changes in isothermal magnetization as though there are two metamagnetic transitions well below T_N. In view of such a resemblance of the properties, we speculate that these Rh-based materials offer a good playground to study toplogical Hall effect in a centrosymmetric structure, with its origin lying in triangular lattice of magnetic R ions; (ii) There is an increasing contribution of electronic scattering with decreasing temperature towards T_N in all cases, similar to Gd2PdSi3, thereby serving as examples for a theoretical prediction for a classical spin-liquid phase in metallic systems due to geometrical frustration.

Further, by adapting an argument by Boucheron et al. we derive Sobolev type moment estimates which hold under these functional inequalities. We illustrate our results with applications to concentration of measure estimates (also of higher order, beyond the case of Lipschitz functions) for various stochastic models, including random permutations, zero-range processes, strong Rayleigh measures, exponential random graphs, and geometric functionals on the Poisson path space.

description: We discuss the implications of new relations between black holes' masses, X-ray luminosities and radio luminosities, as well as the properties of the next generation of radio telescopes, for the goal of finding isolated accreting black holes. Because accreting black holes have radio-to-X-ray flux ratios that increase with decreasing luminosity in Eddington units, and because deep surveys over large fields of view should be possible with planned instrumentation such as LOFAR, radio surveys should be significantly more efficient than X-ray surveys for finding these objects.

description: Luego de alcanzar un pico histórico en 1986, el salario mínimo sufrió una caída estrepitosa, junto con el nivel medio de las remuneraciones, hasta inicios de los noventas. Sin embargo, desde mediados de los noventas se ha incrementado considerablemente, acercándose al nivel promedio de las remuneraciones tanto de trabajadores no calificados como de informales. Este estudio describe el marco institucional del salario mínimo en el mercado laboral peruano y analiza su relación con la distribución de los ingresos laborales para diferentes grupos del mercado laboral (trabajadores no calificados, informales, mujeres y jóvenes). Así mismo, aprovecha las variaciones recientes para identificar los efectos de un alza sobre las remuneraciones y el empleo a lo largo de la distribución de los ingresos laborales. A diferencia de lo que ocurre en otros países de América Latina, en el Perú el efecto del salario mínimo sobre las remuneraciones es muy limitado, afectando sólo a los trabajadores del sector formal cuyo nivel de salarios está alrededor del salario mínimo. Por otro lado, se encuentran efectos más amplios y negativos sobre el empleo tanto en el sector formal como en el informal.

X-ray diffraction measurements reveal that these compounds are single-phase materials and their in-plane lattice parameter depends systematically on the substituting content $x$. The magnetic susceptibility in different magnetic fields, the magnetization at different temperatures, and the resistivity at room temperature were measured, respectively. It is found that the spin gap deduced from the magnetic susceptibility measurements decreases with increasing of $x$ in both Cu- and B-site substitution. No superconductivity was found in these substituted compounds.

Subjects: subject: Mesoscale and Nanoscale Physics (cond-mat.mes-hall)

description: We study the transport properties of an Anderson-Holstein model with orbital degeneracies and a tunneling phase that allows for the formation of dark states. The resulting destructive interference yields a characteristic pattern of positive and negative differential conductance features with enhanced shot noise, without further asymmetry requirements in the coupling to the leads. The transport characteristics are strongly influenced by the Lamb-shift renormalization of the system Hamiltonian. Thus, the electron-vibron coupling cannot be extracted by a simple fit of the current steps to a Poisson distribution. For strong vibronic relaxation, a simpler effective model with analytical solution allows for a better understanding and moreover demonstrates the robustness of the described effects.

description: Chimbote es uno de los principales puertos pesqueros del Perú y alberga una parte importante de las fábricas de harina de pescado del país. Sin embargo, luego de más de cincuenta años de existencia, este puerto está lejos de haberse convertido en un cluster dinámico formado por negocios pesqueros altamente especializados y diversificados. Este trabajo pretende explicar esta situación, usando como tesis que la acción conjunta es primordial en el desarrollo de los clusters dinámicos y que ésta se ve obstaculizada en las actividades económicas que no cuentan con derechos de propiedad claramente establecidos, como es el caso de la pesca de anchoveta. La falta de acción conjunta se aprecia en la persistencia de problemas que afectan la eficiencia colectiva del cluster, como son la contaminación ambiental de la bahía y las deficiencias del puerto de Chimbote. El futuro del cluster pesquero de Chimbote depende de la intensificación de la cooperación entre sus agentes, lo cual requiere de una visión clara y compartida del futuro. Pero también requiere de la adopción de un sistema de cuotas de captura transferible para la anchoveta, que genere los incentivos económicos adecuados para evitar la sobreexplotación de los recursos marinos y el sobredimensionamiento de la industria.

description: We describe the beam characteristics of the first ballistic supermirror neutron guide H113 that feeds the neutron user facility for particle physics PF1B of the Institute Laue-Langevin, Grenoble (ILL). At present, the neutron capture flux density of H113 at its 20x6cm2 exit window is 1.35x10^10/cm^2/s, and will soon be raised to above 2x10^10/cm^2/s. Beam divergence is no larger than beam divergence from a conventional Ni coated guide. A model is developed that permits rapid calculation of beam profiles and absolute event rates from such a beam. We propose a procedure that permits inter-comparability of the main features of beams emitted from ballistic or conventional neutron guides.

(TISUR), y único puerto peruano entregado en concesión hasta el momento. El objetivo es evaluar las características del proceso de concesión, estimar su impacto en la economía e identificar las implicancias de entregar en concesión otros puertos del país. Con este fin, se analizó el modelo utilizado para introducir la participación privada, se examinó si existe evidencia de una mejor operación del puerto con la concesión y se estimó el impacto sobre el bienestar de cada grupo involucrado. Los resultados revelan que la concesión tuvo un efecto positivo neto sobre el bienestar, estimado en 47,7 millones de soles. El principal beneficiado habría sido el Gobierno, que a pesar de perder los flujos resultantes de la operación de la infraestructura, ha resultado más que compensado por otros efectos: el pago inicial, la retribución, la tasa regulatoria y una mayor recaudación. En segundo lugar, los consumidores, quienes reciben una tercera parte de este cambio en el bienestar y, por último, el concesionario. Los grupos perjudicados serían los trabajadores y el grupo de usuarios intermedios.

description: We propose a model for the acceleration of charged particles in interplanetary space that appear during quiet time periods, that is, not associated with solar activity events like intense flares or coronal mass ejections. The interaction of charged particles with modeled turbulent electromagnetic fields, which mimic the fields observed in the interplanetary medium, is studied. The turbulence is modeled by means of a dynamical system,the Gledzer-Ohkitani-Yamada (GOY) shell model, which describes the gross features of the Navier-Stokes equations. The GOY model is used to build a 3-D velocity field, which in turn is used to numerically solve the ideal magneto-hydrodynamic (MHD) induction equation, while the electric field is calculated from the ideal Ohm's law. Particle acceleration in such an environment is investigated by test particle simulations, and the resulting energy distributions are discussed and compared to observations of suprathermal electrons and ions during quiet periods in interplanetary space.

description: We report an ab initio study of the electric-field gradient tensor (EFG) at Cd impurities located at both inequivalent cationic sites in the semiconductor In2O3. Calculations were performed with the FLAPW method, that allows us to treat the electronic structure of the doped system and the atomic relaxations introduced by the impurities in the host lattice in a fully self-consistent way. From our results for the EFG (in excellent agreement with the experiments), it is clear that the problem of the EFG at impurities in In2O3 cannot be described by the point-charge model and antishielding factors.

description: Given the stochastic nature of gene expression, genetically identical cells exposed to the same environmental inputs will produce different outputs. This heterogeneity has been hypothesized to have consequences for how cells are able to survive in changing environments. Recent work has explored the use of information theory as a framework to understand the accuracy with which cells can ascertain the state of their surroundings. Yet the predictive power of these approaches is limited and has not been rigorously tested using precision measurements. To that end, we generate a minimal model for a simple genetic circuit in which all parameter values for the model come from independently published data sets. We then predict the information processing capacity of the genetic circuit for a suite of biophysical parameters such as protein copy number and protein-DNA affinity. We compare these parameter-free predictions with an experimental determination of protein expression distributions and the resulting information processing capacity of E. coli cells. We find that our minimal model captures the scaling of the cell-to-cell variability in the data and the inferred information processing capacity of our simple genetic circuit up to a systematic deviation.

description: A fines de la década pasada el gobierno peruano implementó dos seguros públicos para mejorar el acceso a los servicios de salud de las mujeres y de los niños más pobres de la población: el Seguro Escolar Gratuito (SEG) y el Seguro Materno Infantil (SMI). Según la teoría, dichos seguros deberían haber contribuido a disminuir las barreras de acceso a los servicios de salud, redistribuyendo recursos hacia los más pobres, e induciendo, por lo tanto, a una mejora en la equidad. El presente estudio intenta establecer si este objetivo logró concretarse en la realidad. Un primer nivel de análisis encuentra que la implementación de los seguros tuvo un efecto positivo sobre la cobertura ante los riesgos de salud y que tanto el SEG como el SMI se convirtieron en las principales fuentes de aseguramiento en salud para la población. Esto, a su vez, impactó positivamente sobre el acceso a servicios de salud. Sin embargo, los análisis de incidencia de la afiliación, de los errores de focalización y la estimación de una función de demanda de salud muestran que los beneficios no se concentraron particularmente en los segmentos más pobres de población, sino en los más ricos. El efecto sobre la equidad ha sido, en consecuencia, negativo. El ahora Seguro Integral de Salud, que unifica los seguros estudiados, tiene, pues, una importante tarea pendiente para mejorar la equidad del acceso a los servicios de salud.

description: A challenging problem in both engineering and computer science is that of minimising a function for which we have no mathematical formulation available, that is expensive to evaluate, and that contains continuous and integer variables, for example in automatic algorithm configuration. Surrogate-based algorithms are very suitable for this type of problem, but most existing techniques are designed with only continuous or only discrete variables in mind. Mixed-Variable ReLU-based Surrogate Modelling (MVRSM) is a surrogate-based algorithm that uses a linear combination of rectified linear units, defined in such a way that (local) optima satisfy the integer constraints. This method outperforms the state of the art on several synthetic benchmarks with up to 238 continuous and integer variables, and achieves competitive performance on two real-life benchmarks: XGBoost hyperparameter tuning and Electrostatic Precipitator optimisation.

description: We have analyzed the ${\bar B}^0\to π^0π^0$ puzzle in three kinds of models beyond the standard model (SM). It is shown that the minimal flavor violation (MFV) models, the minimal supersymmetric standard model (MSSM), and the two Higgs doublet models (2HDM) I and II can not give an explanation of the ${\bar B}^0\to π^0π^0$ puzzle within $1 σ$ experimental bounds and the model III 2HDM can explain the puzzle without a conflict with other experimental measurements. If the constraint on $C_{8g}$ from $b\to s g$ is not imposed, for all kinds of insertions considered there are regions of parameter space, where the scalar quark mass is larger (much larger) than the gluino mass in the case of LR or RL (LL or RR), in which the puzzle can be resolved within $1 σ$ experimental bounds.

description: We study both the classical and the quantum target space of (p,q) minimal string theory, using the FZZT brane as a probe. By thinking of the target space as the moduli space of FZZT branes, parametrized by the boundary cosmological constant x, we see that classically it consists of a Riemann surface \CM_{p,q} which is a p-sheeted cover of the complex x plane. However, we show using the dual matrix model that the exact quantum FZZT observables exhibit Stokes' phenomenon and are entire functions of x. Along the way we clarify some points about the semiclassical limit of D-brane correlation functions. The upshot is that nonperturbative effects modify the target space drastically, changing it from \CM_{p,q} to the complex x plane. To illustrate these ideas, we study in detail the example of (p,q)=(2,1), which is dual to the Gaussian matrix model. Here we learn that the other sheets of the classical Riemann surface describe instantons in the effective theory on the brane. Finally, we discuss possible applications to black holes and the topological string.

description: Aiming to identify how marketing tools influence the coffee consumer’s purchasing behavior, a piece of marketing research with exploratory and descriptive analyses, of qualitative nature was accomplished. The survey was used, with structured questionnaires applied to 800 consumers (São Paulo, Belo Horizonte and Rio de Janeiro) in hypermarkets from July to December 2001. The questionnaires were tabulated and analyzed by utilizing the SSPS software (v.10) with descriptive and multivariate statistic analyses. The sample consisted mostly of consumers of the female gender, married, aged between 20 and 40 years, belonging, in general, to the social class B, senior high school educated. Among the marketing tools, it was found that the features related to the produce (flavor, smell and quality) have greater perception and influence on the consumer’s behavior. Price also plays an important role, as part of the sample belongs to social class C. It was verified that the consumer would not regard as relevant tools such as advertisement and package, proving themselves faithful to the brand. The consumer proved indifferent to the appeals and advertising announcements which, in general, are not very attractive.
