description: Gravitational wave (GW) sources are an excellent probe of the luminosity distance and offer a novel measure of the Hubble constant, $H_0$. This estimation of $H_0$ from standard sirens requires an accurate estimation of the cosmological redshift of the host galaxy of the GW source, after correcting for its peculiar velocity. Absence of an accurate peculiar velocity correction affects both the precision and accuracy of the measurement of $H_0$, particularly for nearby sources. We propose a framework to incorporate such a peculiar velocity correction for GW sources. A first implementation of our method to the event GW170817 combined with the Very Large Baseline Interferometry (VLBI) observation leads to a revised value of $H_0= 68.3^{+ 4.6}_{-4.5}$ km/s/Mpc. While this revision is minor, it demonstrates that our method makes it possible for obtaining an unbiased and accurate measurements of $H_0$ at the precision required for the standard siren cosmology.

description: Based on the construction of evaluation index system of marine-land economy system, this paper analyzes the coupling coordination between marine economy and land economy. The coupling coordinative model is used to analyze the coupling coordinative degree of the marine economy and land economy. The results show that from 2002 to 2012, the marine economy and land economy coupling degree was high and it achieved coordination from disorder gradually, resulting in mutual promotion and common development of marine economy and land economy.

description: The chemical characteristics of rapeseed meal (RSM) produced from two cultivars of UK-grown rapeseed, by both supercritical carbon dioxide extraction (ScCO2) and cold-pressed hexane extraction (CpHe) were examined. Their nutritional value, with and without protease, was then assessed in a broiler digestibility trial. Basal feed was substituted with one of four RSM batches (200 g/kg) following adjustments for dry matter (DM) and ether extract (EE) content. Half of each diet was supplemented with a mono-component protease derived from Bacillus subtilis (Axtra®PRO, Danisco Animal Nutrition, Malborough, UK) giving a total of eight test diets. Two control diets, with and without protease were also fed. At 13 d age male Ross 308 broilers were randomly allocated to seven replicate pens (five birds per pen) and assigned to one of 10 diets. Total excreta were collected from 17 to 21 d age and feed intake was recorded. Pre-caecal protein digestibility (pcPd) was determined using TiO2 as an indigestible marker. Colourimetrically CpHe RSM was substantially darker than ScCO2 counterparts. The influence of oil recovery method (ORM) was also evident in DM, EE, ash free neutral detergent fibre (aNDFom), neutral detergent insoluble crude protein (NDICP) and glucosinolate content (GLS). The content of DM, EE and GLS was higher in ScCO2 RSM whereas aNDFom and NDICP levels were greater in CpHe RSM. Protein solubility in KOH was greater in ScCO2 RSM whilst levels of NDICP were lower. Collectively these results suggest that less heat damage was incurred to the RSM during ScCO2 extraction. There was no significant main effect of cultivar nor were any significant interactions observed between treatment factors. Rapeseed meal ScCO2 produced greater metabolisable energy, pcPd, nitrogen retention and energy metabolisability (p p

description: Changes in hydrological processes, such as runoff and transport of sediment and nutrient loads brought about by warming air temperatures and variations in rainfall under climate change pose challenges to the integrated management of water resources at catchment scale. Extreme events are expected to compound these challenges. Most assessments have focused on effects of changes in climate and land use and landcover, but less on the dynamical responses of vegetation and soil to changing climate and the resulting effects on catchment hydrological processes under future conditions. The exploitation and utilization of freshwater resources by humans has changed the natural flow regimes in rivers, but little attention has been paid to the impact on the downstream freshwater aquatic ecosystems as well as saline intrusion within estuaries. Future population growth and sea level rise may exacerbate conflicts in water resource allocations among different users. This thesis assesses the impacts of future climate change, population growth and water resources management on the water resources and hydrodynamics of different systems within the Nerang River catchment of South-east Queensland (SEQ) in Australia.

description: The relation between single particle and ensemble measurements is adressed for semiconductor CdSe nanocrystals. We record their fluorescence at the single molecule level and analyse their emission intermittency, which is governed by unusual random processes known as Levy statistics. We report the observation of statistical aging and ergodicity breaking, both related to the occurrence of Levy statistics. Our results show that the behaviour of ensemble quantities, such as the total fluorescence of an ensemble of nanocrystals, can differ from the time averaged individual quantities, and must be interpreted with care.

 Diagnosis. Similar to P. leniusculus except rostrum with numerous sharp teeth. Postorbital ridges with sharp teeth. Major chela with out patches of setae, width of chela equal to or greater than length of mesial margin. Male abdomen narrower, major chelae heavier than those of female. Carapace length to 50 mm.
 Color in life. Dark brownish green to dark brown dorsally, bright orange ventrally, occasionally blue-green to bright blue with light salmon color below (Eng & Daniels 1982).
 Habitat and depth. Cool, clear, spring-fed lakes, streams; under rocks on clean firm sand or gravel, shallow.
 Range. Streams in Fall River, Hat Creek sub-drainages, area of Pit River connecting them, in Shasta County, California. Type localities Fall River Mills and Hat Creek near Cassel, California.
 Remarks. Riegel (1959) considered P. fortis to be a subspecies of P. nigrescens, and included records of P. fortis in his account of the range of P. nigrescens. His records from Fall River, Fall "City" [sic] Mills, (the correct name is Fall River Mills), and Hat Creek at Cassel surely belong to P. fortis. Eng & Daniels (1982) prepared an extensive report on the threatened Shasta crayfish.

description: Considering a regression model, we address the question of testing the nullity of the regression function. The testing procedure is available when the variance of the observations is unknown and does not depend on any prior information on the alternative. We first propose a single testing procedure based on a general symmetrickernel and an estimation of the variance of the observations. The corresponding critical values are constructed to obtain non asymptotic level-? tests. We then introduce an aggregation procedure to avoid the difficult choice of the kernel and of the parameters of the kernel. The multiple tests satisfy non-asymptotic properties and are adaptive in the minimax sense over several classes of regular alternatives.

description: The focus of modern marketing has shifted from products and enterprise level of traditional marketing to customer level, and customer equity is receiving closer attention. No. 1 document of central government proposed innovating agricultural production and operation system and establishing new agricultural business entities. Seizing these customers becomes a great challenge for pesticide enterprises in the new trend. Therefore, pesticide enterprises need to find out key factors driving customer equity, so as to carry out pertinent marketing and grab the maximum market share. Based on the first-hand survey data, this paper analyzed the influence of value equity, brand equity and relation equity on customer equity by factor analysis and structural equation analysis. It found that the relation equity has the highest driving effect, especially training, community building and visiting experience. Finally, it came up with some recommendations to make pertinent marketing.

description: GeCu$_2$O$_4$ is a high-pressure recoverable cuprate with a strongly tetragonally elongated spinel structure and magnetic lattice formed by $S=1/2$ CuO$_2$ linear chains with frustrated exchange interactions and exotic magnetic behavior. Here we report on the first stabilization of epitaxial thin films of GeCu$_2$O$_4$ on (001)-oriented MgAl$_2$O$_4$ substrate. Developed growth mode, surface morphology, crystal structure and copper valence state were characterized by \emph{in-situ} reflection high-energy electron diffraction, atomic force microscopy, X-ray reflectivity, X-ray diffraction and X-ray photoelectron spectroscopy. The availability of large single-crystalline GeCu$_2$O$_4$ thin films paves road to comprehensive investigation of physical properties including the puzzle of magnetism and multiferroicity in this peculiar compound.

Alfven-like waves along normal-superconductor phase boundaries
Creators: name: Hirsch, J. E.

Subjects: subject: Superconductivity (cond-mat.supr-con)
subject: FOS: Physical sciences

description: Alfven waves are transverse magneto-hydrodynamic waves resulting from motion of a conducting fluid in direction perpendicular to an applied magnetic field, that propagate along the magnetic field direction. I propose that Alfven-like waves can propagate along normal-superconductor phase boundaries in the presence of a magnetic field. This requires charge flow and backflow across the normal-superconductor phase boundary when the boundary moves, which is predicted by the theory of hole superconductivity but not by the conventional theory of superconductivity. The magnetic field and the domain wall energy provide elasticity, and the normal charge carriers' effective mass provides inertia. It is essential that the normal state charge carriers are holes. I propose an experimental search for Alfven-like waves in superconductors.

description: With economic development, the type and form of tourism products are constantly innovated, and rural tourism has become one of the main travel choices of contemporary Chinese people. In 2014, China formulated National New Urbanization Plan, providing a new opportunity for development of rural tourism. In this paper, we first summarize the development situation and connotation of new urbanization and rural tourism, then discuss the mutually reinforcing interaction between the two, analyze the main problems in Chinese rural tourism under new urbanization, and finally put forth the recommendations, in order to better meet the needs of new urbanization, and strive to create a new model of tourism urbanization.

description: We develop methods for constructing explicit generators, modulo torsion, of the K_3-groups of imaginary quadratic number fields. These methods are based on either tessellations of hyperbolic 3-space or on direct calculations in suitable pre-Bloch groups, and lead to the very first proven examples of explicit generators, modulo torsion, of any infinite K_3-group of a number field. As part of this approach, we make several improvements to the theory of Bloch groups for K_3 of any field, predict the precise power of 2 that should occur in the Lichtenbaum conjecture at -1 and prove that the latter prediction is valid for all abelian number fields.

description: Mapping built land cover at unprecedented detail has been facilitated by increasing availability of global high-resolution imagery and image processing methods. These advances in urban feature extraction and built-area detection can refine the mapping of human population densities, especially in lower income countries where rapid urbanization and changing population is accompanied by frequently out-of-date or inaccurate census data. However, in these contexts it is unclear how best to use built-area data to disaggregate areal, count-based census data. Here we tested two methods using remotely sensed, built-area land cover data to disaggregate population data. These included simple, areal weighting and more complex statistical models with other ancillary information. Outcomes were assessed across eleven countries, representing different world regions varying in population densities, types of built infrastructure, and environmental characteristics. We found that for seven of 11 countries a Random Forest-based, machine learning approach outperforms simple, binary dasymetric disaggregation into remotely-sensed built areas. For these more complex models there was little evidence to support using any single built land cover input over the rest, and in most cases using more than one built-area data product resulted in higher predictive capacity. We discuss these results and implications for future population modeling approaches.

 Diagnosis. Similar to P. leniusculus except rostrum concave, with prominent, acute apex; 5 or 6 lateral teeth, small spinules on postorbital ridges. Major chelae without clusters of setae, chela narrow, palm barely wider than closed fingers, fingers may be gaping. Abdominal pleura sharply triangular. Total length 78 mm.
 Color in life. Blackish.
 Habitat and depth. Streams near the coast. Depth not reported.
 Range. Unalaska, Alaska; Fort Steilacoom, Washington, Alameda Creek, Alameda County and Coyote Creek, Santa Clara County, California (Holmes 1900). Type locality given as San Francisco, California, but Stimpson said that he purchased his specimens in a market.
 Remarks. There have been no reliable records of live P. nigrescens since those of Holmes (1900). Subsequent reports by Bonnot (1930) quoted Holmes or considered P. fortis to be a subspecies of P. nigrescens (Riegel 1959). Holmes' specimens probably were burned in the fire following the San Francisco earthquake in 1906, so it is impossible to double-check the identification of his material from Washington and Alaska.

Based on 517 Chinese respondents with access to digital music, using the multiple liner regression model, this study indicates that free ideology, perceived benefits of free downloading, perceived benefits of paid downloading, subjective norm, habit strength have direct influence on WTP, and music affinity and the deterrence effect of the legislation have moderating effects. This study contributes theoretically to research on Chinese consumers’ WTP for digital music and offers practical recommendations for the digital music charging system setup.

On the Phenomenology of Hydrodynamic Shear Turbulence
Creators: name: Longaretti, Pierre-Yves
Publisher: name: arXiv
Year: 2002
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: The question of a purely hydrodynamic origin of turbulence in accretion disks is reexamined, on the basis of a large body of experimental and numerical evidence on various subcritical (i.e., linearly stable) hydrodynamic flows. One of the main points of this paper is that the length scale and velocity fluctuation amplitude which are characteristic of turbulent transport in these flows scale like $Re_m^{-1/2}$, where $Re_m$ is the minimal Reynolds number for the onset of fully developed turbulence. From this scaling, a simple explanation of the dependence of $Re_m$ with relative gap width in subcritical Couette-Taylor flows is developed. It is also argued that flows in the shearing sheet limit should be turbulent, and that the lack of turbulence in all such simulations performed to date is most likely due to a lack of resolution, as a consequence of the effect of the Coriolis force on the large scale fluctuations of turbulent flows. These results imply that accretion flows should be turbulent through hydrodynamic processes. If this is the case, the Shakura-Sunyaev $α$ parameter is constrained to lie in the range $10^{-3}-10^{-1}$ in accretion disks, depending on unknown features of the mechanism which sustains turbulence. Whether the hydrodynamic source of turbulence is more efficient than the MHD one where present is an open question.

description: We extend our models of the vertical structure and emergent radiation field of accretion disks around supermassive black holes described in previous papers of this series. Our models now include both a self-consistent treatment of Compton scattering and the effects of continuum opacities of the most important metal species (C, N, O, Ne, Mg, Si, S, Ar, Ca, Fe, Ni). With these new effects incorporated, we compute the predicted spectrum from black holes accreting at nearly the Eddington luminosity (L/L_Edd = 0.3) and central masses of 10^6, 10^7, and 10^8 M_sun. We also consider two values of the Shakura-Sunyaev alpha parameter, 0.1 and 0.01. Although it has little effect when M > 10^8 M_sun, Comptonization grows in importance as the central mass decreases and the central temperature rises. It generally produces an increase in temperature with height in the uppermost layers of hot atmospheres. Compared to models with coherent electron scattering, Comptonized models have enhanced EUV/soft X-ray emission, but they also have a more sharply declining spectrum at very high frequencies. Comptonization also smears the hydrogen and the He II Lyman edges. The effects of metals on the overall spectral energy distribution are smaller than the effects of Comptonization for these parameters. Compared to pure hydrogen-helium models, models with metal continuum opacities have reduced flux in the high frequency tail, except at the highest frequencies, where the flux is very low. Metal photoionization edges are not present in the overall disk-integrated model spectra. In addition to our new grid of models, we also present a simple analytic prescription for the vertical temperature structure of the disk in the presence of Comptonization, and show under what conditions a hot outer layer (a corona) is formed.

description: We examine the hydrodynamic phonon spectrum of a monolayer film adsorbed on the wall of a spherical pore. Due to the boundary conditions, the monolayer film exhibits a discrete phonon spectrum. The corresponding density of states per unit frequency is thus a set of delta functions and the heat capacity exhibits Arrhenius behavior at low temperatures. At high temperatures, the heat capacity approaches the C ~ T^2 behavior of a two-dimensional monolayer film. Our results for the spherical surface film are compared to previous calculations for films confined to a cylindrical surface.

The algorithm, which we coin Recurrent Multilevel Splitting (RMS), relies on the Markov chain's underlying recurrent structure, in combination with the Multilevel Splitting method. Extensive simulation experiments are performed, including experiments with a nonlinear stochastic model that has some characteristics of complex climate models. The numerical experiments show that RMS can boost the computational efficiency by several orders of magnitude compared to the Monte Carlo method.

description: L-lysine is an essential amino acid used in various industrial sectors but mainly in food and animal feed. Intense research has been directed toward increasing its productivity. This literature review presents the state of the art and patent landscape of the industrial production of L-lysine, with a focus on the strain development and fermentation technologies, through geographic, social, and chronological analysis, using the text mining technique. The geographic analysis showed a greater tendency for countries with industrial plants with large production capacity to submit patents or publish articles, while the social analysis reflected the close relationship between educational units and companies. The technologies of each document were divided into optimization of fermentation parameters, conventional mutation, and genetic engineering. Corynebacterium glutamicum and Escherichia coli present the most attractive industrial phenotypes, and their cultivation occurs mainly in fed-batch processes with control parameters carefully selected to enhance metabolism. These strains are generally modified by conventional approaches (e.g., mutagenesis and selection of auxotrophic and/or regulatory mutants) or by genetic engineering technologies. The combination of both these approaches enables genomic breeding and the construction of strains with industrial potential, capable of accumulating more than 120 g/L of L-lysine. From the analysis of these approaches, we developed a descriptive flow of substrate uptake, amino acid metabolism, and mechanisms of excretion of a lysine-producing model cell. It is expected that the various mechanisms of L-lysine production, here shown and described, will become a guide that aids in increasing amino acid productivity without interfering with the strain stability.

description: We have used the Wisconsin H-Alpha Mapper (WHAM) to observe the spatially extended distribution of ionized hydrogen in M31 beyond the stellar disk. We obtained five sets of observations, centered near the photometric major axis of M31, that extend from the center of the galaxy to just off the edge of the southwestern HI disk. Beyond the bright stellar disk, but within the HI disk, weak H-alpha is detected with an intensity I(H-alpha) = 0.05 (+0.01 / -0.02) Rayleighs. Since M31 is inclined 77 degrees with respect to the line of sight, this implies that the ambient intergalactic ionizing flux onto each side of M31 is Phi_0 <= 1.6 x 10^4 photons cm^-2 s^-1. Just beyond the outer boundary of the HI disk we find no significant detection of H-alpha and place an upper limit I(H-alpha) <= 0.019 Rayleighs.

description: In the context that global grain security is still in very severe situation, the grain security situation in China is not optimistic as well. The “Red Line of Farmland Area” cannot completely solve the grain security problems in China. We still need to seek new breakthroughs in the quality and yield of farmland. The construction of high standard capital farmland is the important premise to guarantee national grain security. On this basis, this paper has summarized the difficulties we are facing in the construction of high standard capital farmland, and has proposed the methods and measures to construct high standard capital farmland and lay a solid foundation for grain security in China.
Correlated X-ray and optical variability in KV UMa

description: We present coordinated X-ray and optical observations of the X-ray transient KV UMa (= XTE J1118+480) at high time resolution. The optical variation associated with spikes in the X-rays consist of a dip preceding the spike by 0-5 s, and a peak following it. The cross-correlation function between X-rays and optical has the same shape. It rises sharply, within 30ms of the peak of the X-rays. The shape of the cross correlation shows significant intrinsic variability on time scales as short as 30s. Analyzing this variability with principal component analysis (calibrated with simulated data), we find two statistically independent components. The first is similar to the average cross-correlation. The second also consists of a dip followed by a peak, but on a 3x shorter time scale. These properties of the optical light, together with the high optical brightness of the transient, are not easily explained by reprocessing of the X-rays.

description: China has strengthened dairy food safety management with both industrial and trade policies since the melamine incident of 2008. Sanitary and Phytosanitary (SPS) measures constitute the majority of non-tariff measures (NTMs) for China’s dairy imports. Both Trade Restrictiveness Indexes (TRIs) and Overall Trade Restrictiveness Indexes (OTRIs) pertaining to SPS measures are greater than tariff rates for China’s dairy imports. The top ten countries that export dairy to China experienced different levels of market access barriers, depending on whether they export concentrated milk or cream. SPS related measures are essential for China to develop a safe dairy industry. Supplying China with safe and high quality dairy goods is the best method for dairy exporters to overcome barriers of China’s SPS measures.

description: The celebrated Michaelis-Menten (MM) expression provides a fundamental relation between the rate of enzyme catalysis and substrate concentration. The validity of this classical expression is, however, restricted to macroscopic amounts of enzymes and substrates and, thus, to processes with negligible fluctuations. Recent experiments have measured fluctuations in the catalytic rate to reveal that the MM equation, though valid for bulk amounts, is not obeyed at the molecular level. In this mini-review, we show how new statistical measures of fluctuations in the catalytic rate identify a regime in which the MM equation is always violated. This regime, characterized by temporal correlations between enzymatic turnovers, is absent for a single enzyme and unobservably short in the classical limit.

description: Objectives: Peptidylarginine deiminases (PADs) are a family of calcium-dependent enzymes catalysing the conversion of arginine residues to citrulline, which may constitute a risk factor in rheumatoid arthritis (RA) pathogenesis. We investigated PAD activation by serum (PADAct) in early RA, and the associations between PAD activation and disease characteristics, treatment response, and progression of radiographic damage. Method: Sera from disease-modifying anti-rheumatic drug (DMARD)-naïve early RA patients (n = 225), classified according to the 2010 American College of Rheumatology/European League Against Rheumatism criteria, and healthy controls (n = 63) were analysed for PAD4 activating capacity at 0, 3, 12, and 24 months using a high-performance liquid chromatography fluorometric method. Associations for PADAct were evaluated by Mann–Whitney U and chi-squared tests. Changes in PADAct levels were compared using the Wilcoxon signed-rank test. Results: PADAct positivity occurred in 42% (n = 95) of the patients and was more prevalent in anti-citrullinated protein antibody (ACPA)-positive vs ACPA-negative patients (47% vs 20%, p = 0.002), but not in rheumatoid factor (RF)-positive vs RF-negative patients (44% vs 38%, p = 0.49). PADAct-positive were younger than PADAct-negative patients [mean ± sd 48.7 ± 13.5 vs 53.2 ± 13.7 years, p = 0.011]. Median [25th, 75th percentile] PADAct levels were higher in patients than in controls (8768 [7491, 11 393] vs 7046 [6347, 7906], p Conclusion: Serum capacity to activate PAD4 was associated with ACPA and RF positivity and earlier disease onset in early RA patients, and decreased after initiation of DMARD treatment, indicating that anti-PAD treatment could potentially be beneficial in RA.
Characterizing the QPO Behavior of the X-ray Nova XTE J1550--564

description: For all 209 RXTE observations of the X-ray nova XTE J1550-564 during its major outburst of 1998-1999, we have analyzed the X-ray power spectra, phase lags, and coherence functions. The phase lags and coherence measures are used to distinguish three types of low-frequency QPOs (one more than those reported by Wijnands, Homan, & van der Klis 1999). For the most common type, the phase lag is correlated with both the QPO frequency and the amplitude. The physical significance of the QPO types is evident in the relationships between QPO properties and the apparent temperature and flux from the accretion disk. There is also a clear pattern in how the QPO types relate to the presence of high-frequency QPOs. In general, both the amplitude and the Q value (freq./FWHM) of low-frequency QPOs decrease as the high-frequency oscillations increase in frequency (100 to 284 Hz) and in Q value. We speculate that the antagonism between low-frequency and high-frequency QPOs arises from competing structures in a perturbed accretion disk. However, we find that the frequencies of slow (< 20 Hz) and fast (> 100 Hz) QPOs are not correlated. In addition, we encounter systematic problems in attempting to reliably compare the QPO frequencies with broad features in the power continuum, since there are a variable number of such features in the power spectra. These results cast some doubt on the reported global relationship between QPOs from neutrons stars and those from black hole systems.
