description: We report the results of a search for 6.4 keV Fe fluorescent emission in Young Stellar Objects (YSOs) with measured accretion luminosities in the rho Oph cloud, using all existing chandra and XMM-Newton observations of the region. A total of nine such YSOs have X-ray data with sufficiently high S/N for the 6.4 keV line to be potentially detected if present. A positive detection of the Fe 6.4 keV line is reported for one object, Elias 29, in both the XMM-Newton and the chandra data. The 6.4 keV line is detected in Elias 29 both during quiescent and flaring emission, unlikely all previously reported detections of 6.4 keV Fe fluorescence in YSOs which were made during intense flaring. The observed equivalent width of the fluorescent line is large, at W_alpha approx 140 eV, ruling out fluorescence from diffuse circumstellar material. It is also larger than expected for simple reflection from a solar-composition photosphere or circumstellar disk, but it is compatible with being due to fluorescence from a centrally illuminated circumstellar disk. The X-ray spectrum of Elias 29 is also peculiar in terms of its high (ionized) Fe abundance, as evident from the very intense Fe xxv 6.7 keV line emission; we speculate on the possible mechanism leading to the observed high abundance.

description: In the discussion of agrarian reform in Brazil, a central concern is the competitiveness of farms on land settlements. This comparative study between milk producers on land settlement schemes and outside aims to enhance understanding of the settlers’ technical and economical potential. The analysis is based on data collected from 39 milk producers from the Rio das Pedras settlement and 42 milk producers located in the bordering municipalities of Uberlândia and Monte Alegre, State of Minas Gerais. The field research took place on April and June but the farm data refer to production, costs, and income occurred in March 2006. We use various technical and economic measures to assess farm performance, though focused on the gross margin per liter and per hectare. The survey results reveal that the average gross margin per liter of milk obtained by producers from outside the settlement was higher than for the settlers. However, the difference in the two averages can be explained by the higher average price per liter obtained by producers from outside the settlement. The larger total gross margin were found among producers ranging from 600 to 1400 liters. Both outside and on the settlement there was wide variation in farm performance. The highest gross margins per liter were obtained on some of the small and medium-size farms, including a few settler farms. The full range of performance indicators which we used did not demonstrate an absolute superiority of non-settler producers over the settlers: producers with poor performance were found among small and large farms, regardless their location. These results lead us to recommend the identification and implementation of actions designed to raise the price of the liter of milk for small scale producers. The study also revealed a need to reassess the optimum intensity of use of purchased feed-stuffs and for the transfer of best practice between farms with similar resource endowments.

description: The Deep Extragalactic Exploratory Probe (DEEP) is a multi-phase research program dedicated to the study of the formation and evolution of galaxies and of large scale structure in the distant Universe. This paper describes the first five-year phase, denoted DEEP1. A series of ten DEEP1 papers will discuss a range of scientific topics (e.g., the study of photometric and spectral properties of a general distant galaxy survey, the evolution observed in galaxy populations of varied morphologies). The observational basis for these studies is the Groth Survey Strip field, a 127 square arcminute region which has been observed with the Hubble Space Telescope in both broad I-band and V-band optical filters and with the Low Resolution Imaging Spectrograph on the Keck Telescopes. Catalogs of photometric and structural parameters have been constructed for 11,547 galaxies and stars at magnitudes brighter than 29, and spectroscopy has been conducted for a magnitude-color weighted subsample of 818 objects. We evaluate three independent techniques for constructing an imaging catalog for the field from the HST data, and discuss the depth and sampling of the resultant catalogs. The selection of the spectroscopic subsample is discussed, and we describe the multifaceted approach taken to prioritizing objects of interest for a variety of scientific subprograms. A series of Monte Carlo simulations then demonstrates that the spectroscopic subsample can be adequately modeled as a simple function of magnitude and color cuts in the imaging catalog.

description: The analysis of market integration of agricultural commodities based on price information are limited because the effects of transaction costs are not considered in the adjustment process. The main objective of this paper was to estimate the possible transaction costs impacts on market integration of beef cattle between the states of Minas Gerais and São Paulo. It was estimated a Threshold Vector Error Correction Model (TVEC model) using monthly price data for the period from January 1972 to August 2005. The results indicated the presence of threshold cointegration implying that transaction costs have important effect on the price adjustment process.

description: Our understanding of the unification of jetted AGN has evolved greatly as jet samples have increased in size. Here, based on the largest-ever sample of over 2000 well-sampled jet spectral energy distributions, we examine the synchrotron peak frequency -- peak luminosity plane, and find little evidence for the anti-correlation known as the blazar sequence. Instead, we find strong evidence for a dichotomy in jets, between those associated with efficient or `quasar-mode' accretion (strong/type II jets) and those associated with inefficient accretion (weak/type I jets). Type II jets include those hosted by high-excitation radio galaxies, flat-spectrum radio quasars (FSRQ), and most low-frequency-peaked BL Lac objects. Type I jets include those hosted by low-excitation radio galaxies and blazars with synchrotron peak frequency above 10^15 Hz (nearly all BL Lac objects). We have derived estimates of the total jet power for over 1000 of our sources from low-frequency radio observations, and find that the jet dichotomy does not correspond to a division in jet power. Rather, type II jets are produced at all observed jet powers, down to the lowest levels in our sample, while type I jets range from very low to moderately high jet powers, with a clear upper bound at ~10^43 erg/s The range of jet power in each class matches exactly what is expected for efficient (i.e., a few to 100% Eddington) or inefficient (<0.5% Eddington) accretion onto black holes ranging in mass from 10^7-10^9.5 M_sol.

description: The strengthening of social organizations that made it possible for dairy production to become a market-driven activity has brought about deep changes in the sexual division of labour. The sociological analysis of the changes in family-farming intra-household roles shows that cultural traditions, gender-related power gaps, and social contexts that further deepen differences in market access between men and women are the social and cultural foundations of a hierarchy structured according to sex and generation, where women, especially the youngest, occupy greatly disadvantageous positions. With the strengthening of cooperatives, dairy production began to occupy a rather important role in providing resources to the household, yet the control over the activity shifted to men. This was an unexpected outcome of how the organizations conducted the process of modernizing the production and restructuring the markets, which further reinforced male control over the household production and increased the gender gap with regard to access to resources.

description: A continuous-time formulation of the Diffusion Monte Carlo method for lattice models is presented. In its simplest version, without the explicit use of trial wavefunctions for importance sampling, the method is an excellent tool for investigating quantum lattice models in parameter regions close to generalized Rokhsar-Kivelson points. This is illustrated by showing results for the quantum dimer model on both triangular and square lattices. The potential energy of two test monomers as a function of their separation is computed at zero temperature. The existence of deconfined monomers in the triangular lattice is confirmed. The method allows also the study of dynamic monomers. A finite fraction of dynamic monomers is found to destroy the confined phase on the square lattice when the hopping parameter increases beyond a finite critical value. The phase boundary between the monomer confined and deconfined phases is obtained.

description: This study simulates North Korean food supply and demand using an econometric regression based upon neo-classical economic theory. In doing so, this study at first describes the autarky condition that exists in the closed economy of North Korea and the relationship between pro-military oriented economic policy and deficiency in the dietary needs required by the average North Korean. This study then quantifies the impact agricultural resources and policy have had on the production of food for the sample period of 1995 to 2008. Results show that food production decreases along with a decrease in agricultural input factors and with the implementation of a more pro-military oriented economic policy. Finally, this study simulates ex ante food balance. In order to meet food demand, the rate at which agricultural input factors are made available should be much more greater than the increasing rate of population, regardless of whether pro-market oriented economic policy reforms are implemented or not. And if a more pro-market approach is implemented by North Korea, the food balance appears to recover more quickly from food deficiency to food surplus given a specific level of agricultural resources.

description: With the launch of SDO, many EUV waves were observed during solar eruptions. However, the joint observations of Moreton and EUV waves are still relatively rare. We present an event that a small-scale filament eruption simultaneously results in a Moreton wave, an EUV wave and a Coronal Mass Ejection in active region NOAA 12740. Firstly, we find that some dark elongate lanes or filamentary structures in the photosphere existed under the small-scale filament and drifted downward, which manifests that the small-scale filament was emerging and lifting from subsurface. Secondly, combining the simultaneous observations in different Extreme UltraViolet (EUV) and H$α$ passbands, we study the kinematic characteristics of the Moreton and EUV waves. The comparable propagating velocities and the similar morphology of Moreton and different passbands EUV wavefronts were obtained. We deduce that Moreton and different passbands EUV waves were the perturbations in different temperature-associated layers induced by the coronal magneto-hydrodynamic shock wave. We also find the refracted, reflected and diffracted phenomena during the propagation of the EUV wave. By using power-law fittings, the kinematic characteristics of unaffected, refracted and diffracted waves were obtained. The extrapolation field derived by the potential field source surface (PFSS) model manifests that the existence of an interface of different magnetic system (magnetic separatrix) result in refraction, reflection and deviation of the EUV wave.

Motion of discrete solitons assisted by nonlinearity management

description: We demonstrate that periodic modulation of the nonlinearity coefficient in the discrete nonlinear Schrödinger (DNLS) equation can strongly facilitate creation of traveling solitons in the lattice. We predict this possibility in an analytical form, and test it in direct simulations. Systematic simulations reveal several generic dynamical regimes, depending on the amplitude and frequency of the time modulation, and on initial thrust which sets the soliton in motion. These regimes include irregular motion, regular motion of a decaying soliton, and regular motion of a stable one. The motion may occur in both the straight and reverse directions, relative to the initial thrust. In the case of stable motion, extremely long simulations in a lattice with periodic boundary conditions demonstrate that the soliton keeps moving as long as we can monitor without any visible loss. Velocities of moving stable solitons are in good agreement with the analytical prediction, which is based on requiring a resonance between the ac drive and motion of the soliton through the periodic potential. All the generic dynamical regimes are mapped in the model's parameter space. Collisions between moving stable solitons are briefly investigated too, with a conclusion that two different outcomes are possible: elastic bounce, or bounce with mass transfer from one soliton to the other. The model can be realized experimentally in a Bose-Einstein condensate trapped in a deep optical lattice.

description: We review the main tools which allow for the statistical characterization of weighted networks. We then present two case studies, the airline connection network and the scientific collaboration network, which are representative of critical infrastructures and social systems, respectively. The main empirical results are (i) the broad distributions of various quantities and (ii) the existence of weight-topology correlations. These measurements show that weights are relevant and that in general the modeling of complex networks must go beyond topology. We review a model which provides an explanation for the features observed in several real-world networks. This model of weighted network formation relies on the dynamical coupling between topology and weights, considering the rearrangement of weights when new links are introduced in the system.

description: This study provides an example of how implicit price and demand models can be developed and used for empirical analysis. In particular, empirical application of these models can quantify the impact of implicit economic variables representing preference, relative price, production efficiency, the degree of price sensitivity to quantity supplied, and substitutability on market price and demand for domestic and imported products. Furthermore, the simultaneous impact of these implicit economic variables on market price and demand can be quantified using these implicit price and demand models.

description: Magnetized Quark Nuggets (MQNs) are a recently proposed dark-matter candidate consistent with the Standard Model and with Tatsumi's theory of quark-nugget cores in magnetars. Previous publications have covered their formation in the early universe, aggregation into a broad mass distribution before they can decay by the weak force, interaction with normal matter through their magnetopause, and first observation consistent MQNs, i.e. a nearly tangential impact limiting their surface-magnetic-field parameter B_o from Tatsumi's values of 0.1 to 10.0 TT to new value of 1.65 TT +/- 21%. The MQN mass distribution and interaction cross section depend strongly on B_o. Their magnetopause is much larger than their geometric dimensions and can cause sufficient energy deposition to form non-meteorite craters, which are reported approximately annually. We report computer simulations of the MQN energy deposition in water-saturated peat, soft sediments, and granite and report results from excavating such a crater. Five points of agreement between observations and hydrodynamic simulations of an MQN impact support this second observation consistent with MQN dark matter and suggest a method for qualifying additional MQN events. The results also redundantly constrain B_o to greater than 0.4 TT.

description: Based on the time-dependent Gutzwiller approximation for the extended Hubbard model we calculate the energy and momentum dependence of spin excitations for striped ground states. Our starting point correctly reproduces the observed doping dependence of the incommensurability in La-based cuprates and the dispersion of magnetic modes in the insulating parent compound. This allows us to make quantitative predictions for the doping evolution of the dispersion of magnetic modes in the stripe phase including the energy and intensity of the resonance peak as well as the velocity of the spin-wave like Goldstone mode. In the underdoped regime $n_h<1/8$ we find a weak linear dependence of $ω_{res}$ on doping whereas the resonance energy significantly shifts to higher values when the charge concentration in the stripes starts to deviate from half-filling for $n_h>1/8$. The velocity $c$ is non-monotonous with a minimum at 1/8 in coincidence with a well known anomaly in $T_c$. Our calculations are in good agreement with available experimental data. We also compare our results with analogous computations based on linear spin-wave theory.

description: In this paper we investigate the short-time decoherence from Ohmic and 1/f noise of single Josephson charge qubit (JCQ). At first, we use the short-time approximation to obtain the dynamics of the open JCQ. Then we calculate the decoherence the measure of which is chosen as the maximum norm of the deviation density operator. It is shown that the decoherence from 1/f noise plays the central role. The total decoherence from Ohmic and 1/f noise is serious at present experiential conditions according to the DiVincenzo criterion.

Typematerial. Holotype (intact ♀, MNHN-IU-2014- 21452), paratypes (2 intact ♀♀, MNHN-IU-2014-21453), anddissectedparatype (♀, figured) from Aplidium lobatum Savigny, 1816, Mont Dore, New Caledonia, Monniot coll., 19 March 1987.
Etymology. The specific name refers to the curved body of the new species as usual for the genus.
Description of female. Body (Fig. 429A, B) vermiform, cylindrical, unsegmented, curved, densely covered with numerous minute setules (setules not shown in Fig. 429 A-C). Bodylength 3.64 mm; body width 0.51 mm at widest region in middle, slightly narrowing in anterior and posterior quarters. Cephalosome poorly defined from metasome (Fig. 429C), with rounded anterior margin. Posterior part of body bearing horizontal sclerotization bar and weak cleft (as vestige of articulation between metasome and urosome) on dorsal surface (Fig. 429E), copulatory pore on ventral surface (Fig. 429F), and shallow posteromedian incision. Caudal rami absent (fully incorporated into posterior margin of abdomen), but 1 small caudal seta present on each side.
Rostrum (Fig. 429D) large, longerthanwide, weakly tapering towards rounded apex; surface covered with numerous setules. Antennule (Fig. 429G) as unsegmented lobe, much wider than long, densely setulose on ventral surface, armed with about 20 small setae. Antenna (Fig. 429H) stout, 3-segmented; coxa and basis unarmed; endopod distinctly shorter than basis, about 1.8 times longerthanwide (44×25 μm); armedwith 6 smallsetae (arranged as 2, 2, and 2) plus stout terminal claw, about half as long as endopod.
Labrum (Fig. 429D) broad with convex posterior margin. Mandible (Fig. 430A) represented only by lobate palp bearing 7 setae distally (4 on outer side and 3 on slightly projecting inner side). Maxillule (Fig. 430B) as lobe bearing 9 setae (3 on medial margin smaller than others). Maxilla (Fig. 430C) distinctly 3-segmented, with 2, 1, and 4 setae on first to third segments, respectively; setae on first segment weakly pinnate, remaining setae naked. Maxillipeds and legs absent.
Male. Unknown.
Remarks. Three characteristic features of N. curvus gen. et sp. nov. serve to differentiate itfrom its congeners: (1) the mandibular palp is armed with 7 setae; (2) the maxilla is distinctly 3-segmented and (3) is armed with 2, 1, and 4 setae on first to third segments, respectively. The presence of a single small caudal seta on the tip of the paired posteriorabdominal lobes seems to be an additional differential feature of the new species.

description: Adding transitions to an equilibrium system increases the activity. Naively, one would expect this to hold also in out of equilibrium systems. This surprising effect is caused by adding heretofore forbidden transitions into less and less active states. We demonstrate, using relatively simple models, how adding transitions to an out of equilibrium system may in fact reduce the activity and even cause it to vanish. We investigate six related kinetically-constrained lattice gas models, some of which behave as naively expected while others exhibit this non-intuitive behavior. We introduce a semi-mean-field approximation describing the models, which agrees qualitatively with our numerical simulation.

description: We construct numerical models of the newly discovered binary pulsar J0737-3039A, both with a fully relativistic, uniformly rotating, equilibrium code that handles arbitrary spins and in the relativistic, slow-rotation approximation. We compare results for a representative sample of viable nuclear equations of state (EOS) that span three, qualitatively different, classes of models for the description of nuclear matter. A future dynamical measurement of the neutron star's moment of inertia from pulsar timing data will impose significant constraints on the nuclear EOS. Even a moderately accurate measurement (

description: With the current methyl bromide (MeBr) system for producing Georgia’s peppers being phased out, alternative fumigant and herbicide systems for producers are analyzed. Using stochastic dominance analyses, two alternatives exceeding MeBr’s yield and financial efficiency were identified. A programming model, incorporating simulation-optimization techniques, generated optimal production and financial plans. Results indicate potential economic viability under alternative systems vis-à-vis the traditional MeBr production system. The Telone II and Chloropicrin combination with Metham potassium may offer a viable substitute for MeBr.

description: We study a mathematical model describing the growth process of a population structured by age and a phenotypical trait, subject to aging, competition between individuals and rare mutations. Our goals are to describe the asymptotic behaviour of the solution to a renewal type equation, and then to derive properties that illustrate the adaptive dynamics of such a population. We begin with a simplified model by discarding the effect of mutations, which allows us to introduce the main ideas and state the full result. Then we discuss the general model and its limitations. Our approach uses the eigenelements of a formal limiting operator, that depend on the structuring variables of the model and define an effective fitness. Then we introduce a new method which reduces the convergence proof to entropy estimates rather than estimates on the constrained Hamilton-Jacobi equation. Numerical tests illustrate the theory and show the selection of a fittest trait according to the effective fitness. For the problem with mutations, an unusual Hamiltonian arises with an exponential growth, for which we show existence of a global viscosity solution, using an uncommon a priori estimate and a new uniqueness result.

subject: conjectural variation model
subject: U.S. catfish industry

description: This paper addresses the issue of competition in the U.S. catfish industry. To this end, a conjectural variation oligopolistic model was developed. The model was estimated econometrically using the Generalized Method of Moments (GMM) procedure. Chi-square analysis implied that catfish processors do not exert market power over farmers or over consumers. The conjectural elasticity was estimated to be 0.073, the oligopoly power index 0.28, and the oligopsony power index 0.68, and none of these values were statistically significant. The results support competitive behavior of the catfish processing sector.

description: We present a simple activity based on the liquid-drop model which allows secondary school students to explore the uses of mathematical models and gain an intuitive understanding of the concept of binding energy, and in particular the significance of positive binding energy. Using spreadsheets provided as Supplementary Material, students can perform simple manipulations on the different coefficients of the model to understand the role of each of its five terms. Students can use the spreadsheets to determine model parameters by optimising the agreement with real atomic mass data. %This will subsequently be used to predict the limit of existence of the Segré chart and to find the minimum mass of a neutron star. This activity can be used as the starting point of a discussion about theoretical models, their validation when it comes to describing experimental data and their predictive power towards unexplored regimes.

Spin Susceptibility in Underdoped Cuprates: Insights from a Stripe-Ordered Crystal

description: We report a detailed study of the temperature and magnetic-field dependence of the spin susceptibility for a single crystal of La(1.875)Ba(0.125)CuO(4). From a quantitative analysis, we find that the temperature-dependent anisotropy of the susceptibility, observed in both the paramagnetic and stripe-ordered phases, directly indicates that localized Cu moments dominate the magnetic response. A field-induced spin-flop transition provides further corroboration for the role of local moments. Contrary to previous analyses of data from polycrystalline samples, we find that a commonly-assumed isotropic and temperature-independent contribution from free carriers, if present, must be quite small. Our conclusion is strengthened by extending the quantitative analysis to include crystals of La(2-x)Ba(x)CuO(4) with x=0.095 and 0.155. On the basis of our results, we present a revised interpretation of the temperature and doping dependence of the spin susceptibility in La(2-x)(Sr,Ba)(x)CuO(4).

description: Cow/calf producers operating in the Dakotas were surveyed on their price discovery strategies, marketing channel preferences, and their perceptions of how regime change in the public price reporting system for fed cattle affected the beef industry in general and the cow/calf industry in particular. Survey results indicate cow/calf producers consider local institutions (auction barns, etc.) to be more reliable for price discovery than regional or national institutions (futures market, USDA public price reports, satellite auctions, etc.). The auction barn marketing channel is the preferred channel for marketing cattle and is considered the most reliable source of market information by producers. Dakota cow/calf producers perceive livestock mandatory price reporting as benefiting the beef industry in general, but consider public price reports to be less reliable than local sources of market information.

description: The impact of Idaho’s wine and grape industry was assessed as an agribusiness and as a tourist industry. Idaho’s grape and wine industry is in its infancy, with wine sales of $15 million from 15 wineries and growers cultivating about 1,000 acres, primarily in southwestern Idaho’s Canyon County. Synthesized output multipliers for wine tourism were virtually identical to the agribusiness output multipliers (1.86 and 2.10 for Canyon County and the state of Idaho, respectively). The wine and grape industry’s agribusiness impact is $15 million in sales and 120 jobs in Idaho, and $23 million and 140 jobs for Canyon County. In contrast, tourism expenditures stimulate other businesses in addition to the agribusiness linkages of grape and wine production. Thus, only about three-fourths of the current wine production would be required to be sold to out-of-region tourists to equal the impact of the wine and grape industry as an agribusiness industry.
Multi-strange baryon production in Au+Au collisions at top RHIC energy as a probe of bulk properties

Subjects: subject: Nuclear Experiment (nucl-ex)
subject: FOS: Physical sciences

description: We report STAR preliminary results on multi-strange baryon production in Au+Au collisions at sqrt(s_NN)=200 GeV at RHIC. Its implication for the formation of a new state of matter is discussed. The system size dependence on the production of strange baryons is investigated to study the onset of strange quark equilibration in the medium. The nuclear modification factor of Lambda, Xi and Omega is also presented. Its suppression at p_T>3 GeV/c supports the formation of a dense interacting medium at RHIC. The spectra of multi-strange baryons reveal that within a hydro-inspired model, they may decouple prior than lighter particles and that their flow may be mostly developed at a partonic level. This idea is emphasized by the measurement of the v_2 of Xi+AntiXi and Omega+AntiOmega whose behaviour is close to the Lambda+AntiLambda baryon elliptic flow in the intermediate p_T region where a constituent quark scaling of v_2 is observed.
