description: We report on the first detection of X-ray dust scattered rings from the Galactic low mass X-ray binary V404 Cyg. The observation of the system with Swift/XRT on June 30 2015 revealed the presence of five concentric ring-like structures centred at the position of V404 Cyg. Follow-up Swift/XRT observations allowed a time-dependent study of the X-ray rings. Assuming that these are the result of small-angle, single X-ray scattering by dust grains along the line of sight, we find that their angular size scales as $θ\propto\sqrt{t}$ in agreement with theoretical predictions. The dust grains are concentrated in five dust layers located at about 2.12, 2.05, 1.63, 1.50 and 1.18 kpc from the observer. These coincide roughly with locations of enhanced extinction as determined by infrared photometry. Assuming that the grain size distribution is described by a generalized Mathis-Rumpl-Nordsieck model, we find that the power-law index of the most distant cloud is $q\sim 4.4$, while $q \sim 3.5-3.7$ in all other clouds. We constrain at a $3σ$ level the maximum grain size of the intermediate dust layers in the range $0.16-0.20\,μ$m and set a lower limit of $\sim 0.2\,μ$m in the other clouds. Hints of an exponential cutoff at the angular intensity profile of the outermost X-ray ring suggest that the smallest grains have sizes $0.01 μ{\rm m}\le α_{\min} \lesssim 0.03\,μ$m. Based on the relative ratios of dust column densities we find the highest dust concentration at $\sim 1.6$ kpc. Our results indicate a gradient in the dust properties within 1 kpc from V404 Cyg.

description: I examine the systematic patterns underlying the amount of media attention obtained by members of Congress from national television broadcasts, including ideological cable news outlets and Sunday morning political talk shows. I posit that members’ media visibility is determined by a two-step process: first, the perceived utility of media appearances for members in pursuing their goals, and second, by their ability to satisfy the media’s crucial objectives of highlighting powerful figures and political conflict. Based on my theory, I predict that ideologically extreme members will make up a disproportionate share of members interviewed on cable news, while institutional leaders within Congress (such as party and committee leaders) will comprise a disproportionate share of members interviewed on the Sunday talk shows. I find that institutional leaders make significantly more appearances on Sunday shows than other members, while ideologically extreme members do not gain a substantively meaningful boost in visibility from these shows relative to less extreme members. Meanwhile, institutional leaders and ideologically extreme members make significantly more appearances on cable news than other members of Congress. My results display that the faces of Congress presented to the public differ across media types, with the goal-seeking behavior of members appearing to reinforce the permanent campaign in Congress.

description: We study a form of cyclic pursuit on Riemannian manifolds with positive injectivity radius. We conjecture that on a compact manifold, the piecewise geodesic loop formed by connecting consecutive pursuit agents either collapses in finite time or converges to a closed geodesic. The main result is that this conjecture is valid for nonpositively curved compact manifolds.

description: In order to fill the knowledge gap on the reduction of losses and waste of bread and other bakery and confectionery products (BBCP) in the selected retail level, studies have been conducted to estimate the scale of waste of this type of food at retailers, cause of occurrence of such losses have been determined, along with methods of limiting and preventing this phenomenon. Data about the scale of losses have been collected by monitoring diary from the sample of small shops (N = 5), bakeries with own shops (N = 5). Additionally, data from a retail network (N = 29 shops) taken from the cash register system. The qualitative data came from 9 individual in-depth reviews with trade experts. The analysis of the data shows that the total volume of losses in BBCP trade in small shops was around 2 kg/week (excluding goods returned for reprocessing). Based on the value BBCP’s losses in the retail network accounted for 42% of the total losses. Moreover, they reach 20% of the bakery & confectionery department turnover. The BBCP returns from trade to reprocessing were recorded at 8-10% of the average daily order value. The 3 main categories of causes behind this phenomenon have been: related to the organisation of the bakery section at the retailer, the manner of displaying products and human errors. The ways of preventing losses and waste in the examined product category have also been named. The obtained results can be used for developing programs and strategies to limit trade losses in bakery & confectionery sections. The examined product category should be understood as the main goal of indexation programs and other steps aiming to limit food waste.

description: Current generation of Internet-based services are typically hosted on large data centers that take the form of warehouse-size structures housing tens of thousands of servers. Continued availability of a modern data center is the result of a complex orchestration among many internal and external actors including computing hardware, multiple layers of intricate software, networking and storage devices, electrical power and cooling plants. During the course of their operation, many of these components produce large amounts of data in the form of event and error logs that are essential not only for identifying and resolving problems but also for improving data center efficiency and management. Most of these activities would benefit significantly from data analytics techniques to exploit hidden statistical patterns and correlations that may be present in the data. The sheer volume of data to be analyzed makes uncovering these correlations and patterns a challenging task. This paper presents BiDAl, a prototype Java tool for log-data analysis that incorporates several Big Data technologies in order to simplify the task of extracting information from data traces produced by large clusters and server farms. BiDAl provides the user with several analysis languages (SQL, R and Hadoop MapReduce) and storage backends (HDFS and SQLite) that can be freely mixed and matched so that a custom tool for a specific task can be easily constructed. BiDAl has a modular architecture so that it can be extended with other backends and analysis languages in the future. In this paper we present the design of BiDAl and describe our experience using it to analyze publicly-available traces from Google data clusters, with the goal of building a realistic model of a complex data center.

description: We present newly derived stellar parameters and the detailed abundances of 19 elements of seven stars with small planets discovered by NASA's Kepler Mission. Each star save one has at least one planet with a radius <= 1.6 R_Earth, suggesting a primarily rocky composition. The stellar parameters and abundances are derived from high signal-to-noise ratio, high-resolution echelle spectroscopy obtained with the 10-m Keck I telescope and HIRES spectrometer using standard spectroscopic techniques. The metallicities of the seven stars range from -0.32 dex to +0.13 dex, with an average metallicity that is subsolar, supporting previous suggestions that, unlike Jupiter-type giant planets, small planets do not form preferentially around metal-rich stars. The abundances of elements other than iron are in line with a population of Galactic disk stars, and despite our modest sample size, we find hints that the compositions of stars with small planets are similar to stars without known planets and with Neptune-size planets, but not to those of stars with giant planets. This suggests that the formation of small planets does not require exceptional host-star compositions and that small planets may be ubiquitous in the Galaxy. We compare our derived abundances (which have typical uncertainties of <= 0.04 dex) to the condensation temperature of the elements; a correlation between the two has been suggested as a possible signature of rocky planet formation. None of the stars demonstrate the putative rocky planet signature, despite at least three of the stars having rocky planets estimated to contain enough refractory material to produce the signature, if real. More detailed abundance analyses of stars known to host small planets are needed to verify our results and place ever more stringent constraints on planet formation models.

description: We consider the Nekrasov-Shatashvili (NS) limit of the five-dimensional superconformal index and propose a novel prescription for selecting the finite contributions. Applying the latter to various examples of U(1) theories, we find that the 5D NS index can be reproduced using recent techniques of Córdova and Shao, who related the 4D Schur index to the BPS spectrum of the theory on the Coulomb branch. In this picture, the 5D instanton solitons are interpreted as additional flavour nodes in an associated 5D BPS quiver.

description: The layered perovskite cobaltite RBaCo$_2$O$_{5.5}$ (R: rare-earth elements or Yttrium) exhibits an abrupt temperature-induced metal$-$insulator transition (MIT) and has been attributed to spin-state ordering (SSO) of Co$^{3+}$ ions. Here we investigated the hole doping member of PrBaCo$_2$O$_{5.5+x}$ ($0 \le x \le 0.24$) with multiple techniques. The analysis on crystal and magnetic structures by electron and neutron diffraction confirm the SSO in the insulating phase of undoped PrBaCo$_2$O$_{5.5}$, which is melted by increasing the temperature across the MIT. In addition, we discovered that hole doping to PrBaCo$_2$O$_{5.5}$ also melts the SSO in conjunction with an insulator-metal transition. The experimental results from electron/neutron diffraction and soft x-ray absorption spectroscopy (XAS) all lead to the conclusion that hole-doping induced MIT occurs is in the same manner as the temperature-induced MIT. Therefore, we propose a unified mechanism that dominates the temperature- and hole-doping-induced MITs in the PrBaCo$_2$O$_{5.5+x}$ system. Specifically, this mechanism involves symmetry breaking coupled with a SSO in the paramagnetic phase.

description: The characteristic is a simple yet important invariant of an algebra. In this paper, we study the characteristic of a Rota-Baxter algebra, called the Rota-Baxter characteristic. We introduce an invariant, called the ascent set, of a Rota-Baxter characteristic. By studying its properties, we classify Rota-Baxter characteristics in the homogenous case and relate Rota-Baxter characteristics in general to the homogeneous case through initial ideals. We show that the Rota-Baxter quotients of Rota-Baxter characteristics have the same underlying sets as those in the homogeneous case. We also give a more detailed study of Rota-Baxter characteristics with special base rings. In particular, we determine the prime characteristics of Rota-Baxter rings.

description: This note provides another proof for the {\em convexity} ({\em strict convexity}) of $\log \det ( I + KX^{-1} )$ over the positive definite cone for any given positive semidefinite matrix $K \succeq 0$ (positive definite matrix $K \succ 0$) and the {\em strictly convexity} of $\log \det (K + X^{-1})$ over the positive definite cone for any given $K \succeq 0$. Equivalent optimization representation with linear matrix inequalities (LMIs) for the functions $\log \det ( I + KX^{-1} )$ and $\log \det (K + X^{-1})$ are presented. Their optimization representations with LMI constraints can be particularly useful for some related synthetic design problems.

description: Intensity scintillations of cosmic radio sources are used to study astrophysical plasmas like the ionosphere, the solar wind, and the interstellar medium. Normally these observations are relatively narrow band. With Low Frequency Array (LOFAR) technology at the Kilpisjärvi Atmospheric Imaging Receiver Array (KAIRA) station in northern Finland we have observed scintillations over a 3 octave bandwidth. ``Parabolic arcs'', which were discovered in interstellar scintillations of pulsars, can provide precise estimates of the distance and velocity of the scattering plasma. Here we report the first observations of such arcs in the ionosphere and the first broad-band observations of arcs anywhere, raising hopes that study of the phenomenon may similarly improve the analysis of ionospheric scintillations. These observations were made of the strong natural radio source Cygnus-A and covered the entire 30-250\,MHz band of KAIRA. Well-defined parabolic arcs were seen early in the observations, before transit, and disappeared after transit although scintillations continued to be obvious during the entire observation. We show that this can be attributed to the structure of Cygnus-A. Initial results from modeling these scintillation arcs are consistent with simultaneous ionospheric soundings taken with other instruments, and indicate that scattering is most likely to be associated more with the topside ionosphere than the F-region peak altitude. Further modeling and possible extension to interferometric observations, using international LOFAR stations, are discussed.

description: A phase diagram for the step faceting phase, the step droplet phase, and the Gruber-Mullins-Pokrovsky-Talapov (GMPT) phase on a crystal surface is obtained by calculating the surface tension with the density matrix renormalization group method. The model based on the calculations is the restricted solid-on-solid (RSOS) model with a point-contact-type step-step attraction (p-RSOS model) on a square lattice. The point-contact-type step-step attraction represents the energy gain obtained by forming a bonding state with orbital overlap at the meeting point of the neighbouring steps. Owing to the sticky character of steps, there are two phase transition temperatures, $T_{f,1}$ and $T_{f,2}$. At temperatures $T < T_{f,1}$, the anisotropic surface tension has a disconnected shape around the (111) surface. At $T

description: The present study examined the characteristics of panic disorder and current treatments available for individuals seeking management of their panic-related symptoms. Panic disorder and agoraphobia, their impact on quality of life, and areas of dysfunction in various life domains for individuals with panic disorder are presented. Also presented is as an overview of rehabilitation counseling and its scope of practice, as it relates to possible areas of treatment and rehabilitation of individuals with panic disorder. Participants in the study were persons with panic disorder who were surveyed on treatments currently or previously received for panic-related symptoms, and their perceptions of the value or effectiveness of these services. These participants will then be asked about services they had not received, but perceived to be of possible value in coping with panic disorder symptoms and dysfunction as a consequence of panic symptoms in significant life areas. Services provided in the rehabilitation counseling scope of practice will be discussed in relation to survey responses, as well as implications for rehabilitation counselors.

description: The aim of the article is to recognise the characteristics of farms with loss of agricultural income, as well as to determine factors shaping income in this type of units. In the article, unpublished individual data of farms continuously keeping agricultural accounts in the FADN system in the period 2004-2019 were used. It was found that the productivity of intermediate consumption has a significant influence on the formation of the income situation. In the group of larger loss-making farms, the impact of asset value was statistically insignificant. This means that it is relatively poorly managed. The same is true of debt, whose low efficiency of use translates into failed investments (or overinvestment). In the context of the conducted analyses it can be concluded that there is a group of farms which to some extent adapted to the existing support system, and the considerable assets, provide safety for their functioning also in the context of the possibility to obtain credits.

description: Obstructive sleep apnea (OSA) is gaining attention across the nation with a high prevalence in the United States. Limited research is available on the association between OSA and chronic oral health conditions, such as chronic periodontitis (CP) and temporomandibular disorder (TMD). The first chapter investigated an association between CP and OSA in a case-control study of 48 subjects. In the adjusted model, our results yielded that subjects with symptomatic mild OSA (OR=0.13, 95% CL: 0.01, 1.53) or moderate/severe OSA (OR=0.13, 95% CL: 0.01,1.29) were less likely to have moderate/severe CP than subjects without OSA. The second chapter explored if OSA risk predicted first-onset TMD independently of sleep and awake bruxism in a prospective cohort study of 2,660 subjects. We found that subjects with two or more signs/symptoms of OSA had 72% greater incidence of first-onset TMD than those with fewer signs/symptoms, independently of reported sleep and awake bruxism.

The western border of Carara National Park (CNP) and its surroundings were characterized at a landscape level in order to consider their implications for biodiversity conservation. 54 400 hectares of Costa Rican Central Pacific tree cover were analyzed (1997, 2000, 2005) to calculate the size of the PAs, mean shape index, mean patch fractal dimension and edge density. Aside from that, we performed eight habitat evaluations on the western border of the CNP (costanera-sur highway) to assess tree composition, regeneration, litter, horizontal obstruction, and canopy cover. It was determined that the PAs were between 36 and 5 242 hectares long. We observed that the tree cover increased from 21 231,8 hectares in 1997 to 29 006,9 hectares in 2000, and decreased to 26 933,4 hectares in 2005. We found out that most of the tree cover (2005) belongs to CNP and ZP Cerros de Turrubares, but both of them present high values of edge density and mean shape index, suggesting that they are susceptible to alteration and fragmentation. The four evaluated points have a similar successional stage. In order to maintain the potential of CNP as an area for biodiversity conservation, we recommend reducing the maximum speed limit in the region adjacent to the park. It is also important to establish frequent monitoring of the tree cover and promote reforestation programs to create corridors that stop the area's fragmentation and facilitate biodiversity conservation.

description: Given a Lorentzian manifold $(M,g_L)$ and a timelike unitary vector field $E$, we can construct the Riemannian metric $g_R=g_L+2ω\otimesω$, being $ω$ the metrically equivalent one form to $E$. We relate the curvature of both metrics, especially in the case of $E$ being Killing or closed, and we use the relations obtained to give some results about $(M,g_L)$.

description: We report on a study that compares the properties of magnetic clouds (MCs) during the first 73 months of solar cycles 23 and 24 in order to understand the weak geomagnetic activity in cycle 24. We find that the number of MCs did not decline in cycle 24, although the average sunspot number is known to have declined by ~40%. Despite the large number of MCs, their geoeffectiveness in cycle 24 was very low. The average Dst index in the sheath and cloud portions in cycle 24 was -33 nT and -23 nT, compared to -66 nT and -55 nT, respectively in cycle 23. One of the key outcomes of this investigation is that the reduction in the strength of geomagnetic storms as measured by the Dst index is a direct consequence of the reduction in the factor VBz (the product of the MC speed and the out-of-the-ecliptic component of the MC magnetic field). The reduction in MC-to-ambient total pressure in cycle 24 is compensated for by the reduction in the mean MC speed, resulting in the constancy of the dimensionless expansion rate at 1 AU. However, the MC size in cycle 24 was significantly smaller, which can be traced to the anomalous expansion of coronal mass ejections near the Sun reported by Gopalswamy et al. (2014a). One of the consequences of the anomalous expansion seems to be the larger heliocentric distance where the pressure balance between the CME flux ropes and the ambient medium occurs in cycle 24.

description: We study the effect of localized magnetic moments on the conductance of a helical edge. Interaction with a local moment is an effective backscattering mechanism for the edge electrons. We evaluate the resulting differential conductance as a function of temperature $T$ and applied bias $V$ for any value of $V/T$. Backscattering off magnetic moments, combined with the weak repulsion between the edge electrons results in a power-law temperature and voltage dependence of the conductance; the corresponding small positive exponent is indicative of insulating behavior. Local moments may naturally appear due to charge disorder in a narrow-gap semiconductor. Our results provide an alternative interpretation of the recent experiment by Li et al. \cite{Li15} where a power-law suppression of the conductance was attributed to strong electron repulsion within the edge, with the value of Luttinger liquid parameter $K$ fine-tuned close to $1/4$.

Universal nature of the nonlinear stage of modulational instability

Year: 2015
Subjects: subject: Pattern Formation and Solitons (nlin.PS)

description: We characterize the nonlinear stage of modulational instability (MI) by studying the long-time asymptotics of focusing nonlinear Schrodinger (NLS) equation on the infinite line with initial conditions that tend to constant values at infinity. Asymptotically in time, the spatial domain divides into three regions: a far left field and a far right field, in which the solution is approximately equal to its initial value, and a central region in which the solution has oscillatory behavior and is described by slow modulations of the periodic traveling wave solutions of the focusing NLS equation. These results demonstrate that the asymptotic stage of MI is universal, since the long-time behavior of a large class of perturbations is described by the same asymptotic state.

The iodine-plutonium-xenon age of the Moon-Earth system revisited

Year: 2015
Subjects: subject: Earth and Planetary Astrophysics (astro-ph.EP)

description: From iodine-plutonium-xenon isotope systematics, we re-evaluate time constraints on the early evolution of the Earth-atmosphere system and, by inference, on the Moon-forming event. Two extinct radioactivites (129I, T1/2 = 15.6 Ma, and 244Pu, T1/2 = 80 Ma) have produced radiogenic 129Xe and fissiogenic 131-136Xe, respectively, within the Earth, which related isotope fingerprints are seen in the compositions of mantle and atmospheric Xe. Recent studies of Archean rocks suggest that xenon atoms have been lost from the Earth's atmosphere and isotopically fractionated during long periods of geological time, until at least the end of the Archean eon. Here we build a model that takes into account these results. Correction for Xe loss permits to compute new closure ages for the Earth's atmosphere that are in agreement with those computed for mantle Xe. The minimum Xe formation interval for the Earth- atmosphere is 40 (-10+20) Ma after start of solar system formation, which may also date the Moon-forming impact.

Restoration of estuarine habitats supports changes in nitrogen cycling and removal over time
Creators: name: Onorevole, Kathleen
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2016

description: Salt marshes and oyster reefs can be restored as living shorelines to prevent coastal erosion and provide ecosystem functions, including denitrification. This microbial process transforms N to a non-bioavailable gas, possibly also producing the powerful greenhouse gas N2O. This study used a chronosequence space-for-time replacement design spanning 0 to 20 years to evaluate N cycling following restoration. Sediment cores were collected seasonally. Dissolved N2 and O2 fluxes in the overlying water were analyzed with a membrane inlet mass spectrometer (MIMS). Denitrification always increased from the 0- to 7-year-old sites; changes in rates between the 7- and 20-year-old sites were not consistent across seasons. Sediment oxygen demand (SOD) was significantly correlated with annual denitrification and may be a viable proxy. These habitats may be a small sink for N2O. This research shows that restored salt marshes and oyster reefs can augment denitrification without increasing fluxes of N2O.

description: The aim of the study was to evaluate the economic efficiency of spring triticale varieties at different levels of production intensity. Three-year field results for the years 2017, 2018 and 2020 were used for the calculations. Factors such as tillage methods (conventional and reduced tillage), varying levels of nitrogen fertilisation (0, 70 and 100 kg N/ha) and varieties – Sopot and Milewo – were included in the analysis. Direct surplus was used as a measure of economic efficiency. The economic efficiency of spring triticale cultivation was assessed taking into account the use of one of the main production factors, i.e. land. For individual variants of the experiment, the gross profitability index was calculated as the ratio of production value to direct costs. The analysis of the production-economic indices showed that the technology with the use of traditional tillage (plough) and a nitrogen fertilisation rate of 70 kg N/ha were the more favourable variant for spring triticale cultivation. It was also found that the level of obtained direct surplus was more influenced by the level of obtained yields and purchase prices of triticale than by the level of direct costs incurred for tillage and sowing operations.

description: The statement of the Riemann hypothesis makes sense for all global fields, not just the rational numbers. For function fields, it has a natural restatement in terms of the associated curve. Weil's work on the Riemann hypothesis for curves over finite fields led him to state his famous "Weil conjectures", which drove much of the progress in algebraic and arithmetic geometry in the following decades. In this article, I describe Weil's work and some of the ensuing progress: Weil cohomology (etale, crystalline); Grothendieck's standard conjectures; motives; Deligne's proof; Hasse-Weil zeta functions and Langlands functoriality.
