Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: We present a concept for a spacecraft that can controllably alter the trajectory of an Earth threatening asteroid using gravity as a towline. The spacecraft hovers near the asteroid with thrusters angled outward so the exhaust does not impinge on the surface. This deflection method is insensitive to the structure, surface properties, and rotation state of the asteroid.

description: The discussions of ethics and literature, like discussions of psychology and literature, law and Literature, usually tend to fall into the cadre of familiar patterns. One major part of the discussion is apprehensive with the depiction of ethical relations in literature. While a reader or the commentators focus on this viable question, they are generally concerned with the ethical effects of reading the work of art.

description: Condensation occurs in nonequilibrium steady states when a finite fraction of particles in the system occupies a single lattice site. We study condensation transitions in a one-dimensional zero-range process with a single defect site. The system is analysed in the grand canonical and canonical ensembles and the two are contrasted. Two distinct condensation mechanisms are found in the grand canonical ensemble. Discrepancies between the infinite and large but finite systems' particle current versus particle density diagrams are investigated and an explanation for how the finite current goes above a maximum value predicted for infinite systems is found in the canonical ensemble.

description: We propose that the different angular distributions in two-photon collisions observed at low and high center-of-mass energies $W_{γγ}$ indicate the transition from nonperturbative to perturbative QCD. We calculate the differential cross sections of $γγ\toππ$, $KK$ in the angle $θ$ of one of the final-state mesons using QCD sum rules and the perturbative QCD approach based on $k_T$ factorization theorem. Our predictions from sum rules (perturbative QCD) decrease (increase) with $|\cosθ|$, consistent with the Belle data of $γγ\to K^+K^-$ for $W_{γγ}\approx 1.5$-1.7 (2.2-2.4) GeV.

description: As proteins typically have charges of around 10, they will interact strongly with charged surfaces. We calculate the electrostatic contribution to the interaction of crystals of protein with charged surfaces. The surfaces repel like-charged crystals and attract oppositely-charged crystals, with free energies which can be easily several kT per protein molecule brought into contact with the surface. This means that oppositely charged surfaces can act as a nucleant, they can induce nucleation of a protein crystal by lowering the free energy barrier to heterogeneous nucleation of the crystal from a dilute solution.

description: Coordination is important in large-scale software development because of the many people involved and the complex dependencies present in software tasks. Even small improvements in productivity can lead to substantial cost-savings and competitive advantage. But despite great technological advances in software engineering and collaboration tools in recent years, coordination in software development projects continues to be problematic. Traditional theories suggest that team members coordinate by programming their tasks and by communicating with each other, but more recent research also suggest that they coordinate through work familiarity and team cognition mechanisms like shared mental models. This paper reports on the results of a multi-method research investigation of how shared mental models, work familiarity and geographic dispersion affect coordination in software teams. This research is based on three studies conducted at a large telecommunications company: face-to-face interviews, survey, and archival studies. Results show that shared mental models have a positive effect on team coordination and that prior familiarity with the same software parts and projects reduces software development time. Results also indicate that geographic dispersion increases software development time and that the effect of work familiarity is stronger for geographically distributed teams than for co-located teams.

description: BINSWANGER, HANS PETER. The Measurement of Biased Efficiency Gainp in U, S. and Japanese Agriculture to Test the Induced Innovation Hypothesis. (Under the direction of RICHARD ADAMS KING.) The basic purpose of this study was to test the induced innovation hypothesis at a very basic level. The hypothesis states that biases in efficiency gains arising from technical change and other sources are endogenously determined by economic forces rather than exogenously by the physicaJ., chemical and biological laws of nature. The key ide;:i of the test i1;, as follows: If biases are determined exogenously, two countries with different factor endowments and differ­ences in other economic variables would experience the same patterns of biases over a prolonged period of time. If the biases differ, there is a strong presumption that these differences have been determined by endogenous economic forces. Biases were measured for the agricultural sectors of the United States and Japan, Estimation equations for the biases in the case of a many-factor production process were developed using a Transcendental Logarithmic cost function in factor-augmenting form. Using these equations it is possible to divide observed share changes into a com­ponent due to efficiency gains and a component due to price changes, The components due to efficiency gains were then used to construct indices of biases, The application of this method required that one first estimate the parameters of the Translog cost function. This was done with cross­section sta:e data for the United States using generalized least squares techniques. The estimated parameters also provided estimates of a set of elasticities and cross elasticities of factor demand and a set of elasticities of substitution. The resulting indices of bias indicate marked differences between the United States and the Japanese experience. The conclusion reached is that the basic premise of the induced innovation hypothesis is cor­rect, Biases are determined by economic forces. However, little evidence as to the precise inducement mechanisms was found.

description: We analyze the phenomenon of nonlinear stochastic resonance (SR) in noisy bistable systems driven by pulsed time periodic forces. The driving force contains, within each period, two pulses of equal constant amplitude and duration but opposite signs. Each pulse starts every half-period and its duration is varied. For subthreshold amplitudes, we study the dependence of the output signal-to-noise ratio (SNR) and the SR gain on the noise strength and the relative duration of the pulses. We find that the SR gains can reach values larger than unity, with maximum values showing a nonmonotonic dependence on the duration of the pulses.

description: The Vygotskian preschool education program (VPEP) is built around mediation in the context of preschool age-specific activities such as sociodramatic play, constructive play, listening and retelling fairy tales, playing with dollhouses, motor activities, and some others. We used the VPEP as part of the daily curriculum in two pre-K classes at PS 197 in Harlem, New York, to promote the development of children’s self-regulation and symbolic thought. Another pre-K class at PS 197 was used as the control group. For pre- and posttests, we administered the Coding and Symbol Search subtests of the Wechsler Preschool and Primary Scale of Intelligence–III (WPPSI-III), which target the ability to self-regulate, and the Block Design subtest of the WPPSI-III, which targets the ability to exercise symbolic thought. The results of the study demonstrate that the VPEP promotes the development of preschoolers’ self-regulation and is beneficial for the development of their symbolic thought.

description: We present a detailed spectral analysis of the black hole candidate MAXI J1836-194. The source was caught in the intermediate state during its 2011 outburst by Suzaku and RXTE. We jointly fit the X-ray data from these two missions using the relxill model to study the reflection component, and a steep inner emissivity profile indicating a compact corona as the primary source is required in order to achieve a good fit. In addition, a reflection model with a lamp-post configuration (relxilllp), which is normally invoked to explain the steep emissivity profile, gives a worse fit and is excluded at 99% confidence level compared to relxill. We also explore the effect of the ionization gradient on the emissivity profile by fitting the data with two relativistic reflection components, and it is found that the inner emissivity flattens. These results may indicate that the ionization state of the disc is not constant. All the models above require a supersolar iron abundance higher than 4.5. However, we find that the high-density version of reflionx can describe the same spectra even with solar iron abundance well. A moderate rotating black hole (a* = 0.84-0.94) is consistently obtained by our models, which is in agreement with previously reported values.

description: In this paper, we present a novel method to test the Einstein's Equivalence Principle (EEP) using (simultaneous) multi-wavelength radio observations of polarized blazars. We analyze simultaneous multi-wavelength polarization observations of 3C 279 at 22, 43, and 86 GHz obtained by two antennas of the Korean VLBI Network. We obtained 15 groups of polarization data, and applied the Metropolis-Hastings Markov Chain (MHMC) to simulate the parameters when considering the EEP effect and the simplest form of Faraday rotation (single external Faraday screen). The final results show the constraint of the parameterized post-Newtonian (PPN) parameter $γ$ discrepancy as $Δγ_{p} = (1.91\pm0.34)\times10^{-20}$. However, the single external Faraday screen is an oversimplification for blazars because there are numerous observations show complex Faraday rotation behavior for blazars due to internal/external Faraday dispersion, beam depolarization, etc. The value $Δγ_{p}$ results of this paper can only be considered as upper limits. Only if all other effects are revealed and considered, should the result be taken as a direct measurement of the violation of the EEP.

description: This paper presents an analysis of technical efficiency and technology gap ratio (TGR) in greenhouse cucumber in Fars Province, Iran. Cucumber production was chosen for this study for the reason that greenhouse productions in this province mainly have focused on this product. The data used in this study was obtained from a random sample of 127 greenhouse s in Fars Province for 2010 to 2011. Metafrontier production function model for firms was used within the parametric framework of stochastic frontier analysis (SFA). The frontier models are applied in the analysis of cross-sectional data by assuming a translog functional form. Results indicate that eliminating energy input subsidies has led to significant decrease in green- house cucumber production efficiency so that the mean technical efficiency declined from 98% to 67 % during 2010-2011. Furthermore, subsidies elimination has also led to decrease of the mean technology gap ratio in greenhouses from 0.92 to 0.87, in other words, it has caused more distance from efficient production frontier.

description: Present study investigates the effect of soaring residential electricity price on the welfare of rural individuals in Guilan Province by Almost Ideal Demand System (AIDS) in which the elasticity’s and welfare variations were calculated by Compensation Variations (CV) and Equivalent Variations (EV) for the time period of 1991-2012. It was shown that the absolute value of income and price elasticity of electricity was less than one unit. Low price elasticity of the demand shows the slight impact of price variations on the demand for electricity in the studied period, on the one hand, and the lack of an appropriate substitute for electricity in residential sector, on the other hand. The calculation of welfare variations and its comparison with the share of electricity in the paid subsidy shows that with 50% and 100% increase in residential electricity price, the cash paid to the households is less that the amount acquired. Accordingly, it can be argued that the direct effect of residential electricity price modification (increase) has not been compensated. In fact, the welfare loss of the households, due to more expensive electricity, is more than the acquired welfare. Yet, in a gradual increase scenario, the calculated CV is less than the payments to the families, and hence it is the only price policy that does not impose a loss on families and improves their welfare.

description: The crystal of a new tetrachlorocobalt(II) anion salt, [BzPy]2[CoCl4] (1) ([BzPy]+ = benzyl pyridinium), was grown by the slow evaporation solution growth method at room temperature. The salt 1 crystallizes in the monoclinic space group P2(1)/c and consists of two [BzPy]+ cations and one [CoCl4]2− anion in which the Co(II) ion is coordinated by four Cl atoms in a close to tetrahedral geometry. The crystal packing is stabilized by electrostatic interactions and C − H···Cl hydrogen bonds between [BzPy]+ cations and [CoCl4]2− anions. Powder XRD diffraction study confirms the crystalline nature and purity of the title compound. The Fourier transform infrared (FT-IR) spectrum was recorded and analyzed with the aid of DFT calculations in order to make a suitable assignment of the observed bands. The thermal stability of the hybrid crystal was analyzed by TG-DTA techniques revealing that the title crystal was stable up to 195 °C. The title salt exhibits violet and cyan fluorescence emissions upon excitation at 345 nm and weak antiferromagnetic interactions in the temperature range 2-300 K. The nonlinear optical (NLO) effect of this compound was predicted using DFT, suggesting that the title crystal is a good material for NLO applications.

description: Due to some accidents and illnesses, it is possible that bones are damaged and require repair, or it may be that bone need to be formed in jaw before dental implant. In some cases, medical intervention is required as the body cannot heal itself. Many approaches are used to repair bone defects in reconstructive medicine, with one of the most popular being the use of allograft bone. Surgeons have a variety of bone allograft structures and shapes to choose from in order to fill in a defect.
The aim of this study is to evaluate the increase in bone regeneration caused by different 3D bone matrix allografts, and asses this effectiveness by in vitro and in vivo models. In the laboratory phase, bone allografts of different shapes and sizes were seeded with mesenchymal stem cells for three weeks. Cell seeding on bone allografts, safety and cell proliferation were evaluated. To investigate the osteoinduction properties of allografts, the expression of osteogenic genes based on selective housekeeping genes using Real–Time PCR was assessed. The alkaline phosphatase enzyme activity in cells was measured by ELISA. In the dentistry phase, focus was made on the use of different size and shape of bone allografts for the treatment of sinus lift in humans. Radiographic evidence was used to evaluate the new bone formation after sinus lift and bone repairing was evaluated by CT scanning. Results showed all products have cell seeding capability. MTT assay tests revealed that none of the allografts exerted cytotoxic properties on Mesenchymal stem cells. Scanning electron microscopy images showed the appropriate pore size for stem cell seeding. The qualitative result of Alizarin red staining test indicates that mineral bone allografts of different structures, such as; cube product and bone powder size of 500- 1000 μm, have the highest mineralization. The expression of osteogenic-related genes increased significantly compared to the negative control group. ATP5B and RPL13A genes were selected as the best reference genes. The results show successful bone formation of allografts as extracellular matrix scaffolds both in vitro and in vivo conditions which have the necessary characteristics for stem cell proliferation and differentiation. This study can help the surgeon to choose suitable bone allograft based on their requirements.
Tidal dissipation in rotating giant planets

description: [Abridged] Tides may play an important role in determining the observed distributions of mass, orbital period, and eccentricity of the extrasolar planets. In addition, tidal interactions between giant planets in the solar system and their moons are thought to be responsible for the orbital migration of the satellites, leading to their capture into resonant configurations. We treat the underlying fluid dynamical problem with the aim of determining the efficiency of tidal dissipation in gaseous giant planets. In cases of interest, the tidal forcing frequencies are comparable to the spin frequency of the planet but small compared to its dynamical frequency. We therefore study the linearized response of a slowly and possibly differentially rotating planet to low-frequency tidal forcing. Convective regions of the planet support inertial waves, while any radiative regions support generalized Hough waves. We present illustrative numerical calculations of the tidal dissipation rate and argue that inertial waves provide a natural avenue for efficient tidal dissipation in most cases of interest. The resulting value of Q depends in a highly erratic way on the forcing frequency, but we provide evidence that the relevant frequency-averaged dissipation rate may be asymptotically independent of the viscosity in the limit of small Ekman number. In short-period extrasolar planets, if the stellar irradiation of the planet leads to the formation of a radiative outer layer that supports generalized Hough modes, the tidal dissipation rate can be enhanced through the excitation and damping of these waves. These dissipative mechanisms offer a promising explanation of the historical evolution and current state of the Galilean satellites as well as the observed circularization of the orbits of short-period extrasolar planets.

description: This study aims to analyze the determinants of vertical integration (ownership and contracting) among peasant farmers in Northern Algeria. The choice of asset control is between ownership and a simple contracting. Thus, the integration of vertical stages of agricultural production leads to higher gross margins, influences the choice of marketing and supply channels, and improves market participation of farmers. Three different regression models were used to determine the likelihood of a peasant household to integrate vertically (and horizontally) in its enterprise. Data were collected from 635 smallholder farmers in Northern Algeria. Farm structure, farm size, farmers' age, farmers’ level of education, seasonality, and geographical location were assumed to be the key factors in accounting for a household’s likelihood to vertically integrate in its farming enterprise. These key factors affect the household’s likelihood of horizontal integration. The study, then, carries the implication that policy-makers should develop increased awareness of farm structure, its scale, seasonal and spatial nature of agricultural production, as well as of some farmers’ social characteristics in order to be able to improve the agricultural productivity.

description: Along the years HiRes and AGASA experiments have explored the fluorescence and the ground array experimental techniques to measure extensive air showers, being both essential to investigate the ultra-high energy cosmic rays. However, such Collaborations have published contradictory energy spectra for energies above the GZK cut-off. In this article, we investigate the acceptance of fluorescence telescopes to different primary particles at the highest energies. Using CORSIKA and CONEX shower simulations without and with the new pre-showering scheme, which allows photons to interact in the Earth magnetic field, we estimate the aperture of the HiRes-I telescope for gammas, iron nuclei and protons primaries as a function of the number of simulated events and primary energy. We also investigate the possibility that systematic differences in shower development for hadrons and gammas could mask or distort vital features of the cosmic ray energy spectrum at energies above the photo-pion production threshold. The impact of these effects on the true acceptance of a fluorescence detector is analyzed in the context of top-down production models.

description: Currently, water, as the most limiting factor in production, determines the priority of planting in different areas of Iran. Saffron is one of the good candidates for drought conditions since it has high economic value and low water requirements that can help with sustainable development. By identifying the factors influencing the decision on saffron cultivation and its expansion, appropriate policies can be implemented to improve the planting of this crop. Marand, located in East Azarbaijan Province, Iran, is one of the areas where farmers have started to grow saffron in recent years. The allocation of 68 hectares of agricultural land to this crop has turned the county into the hub of saffron production in the northwest of the country. This study investigated the factors affecting the decision on saffron cultivation and its development in Marand. To this end, a total of 140 farmers from two groups of saffron growers and non- saffron growers were chosen, and the Heckman’s two-step procedure was then employed. The results of estimating the first step of the Heckman procedure showed that age, familiarity with saffron growing, attending saffron training courses, the number of extension courses, marketing status, and profit status of saffron all had a positive effect on the decision on growing saffron. Moreover, the results of estimating the linear pattern of the second phase corroborated the view that the farmer’s education level, the total area under agricultural and horticultural cultivation, as well as features of agricultural land had a positive impact, and access to water resources had a negative effect on the cultivation area of saffron.
Spatial and temporal boundaries in global teams : Distinguishing where you work from when you work

description: While spatial boundaries include the geographic differences among team members (e.g., different cities), temporal boundaries include the workday differences among team members (e.g., different time zones). In global teams, members have to deal with both spatial and temporal boundaries, since their co-workers are often located in cities within and across time zones. For global team members with high spatial boundaries and low temporal boundaries (e.g., different cities in the same time zone), synchronous communication technologies such as the telephone and instant messenger provide a means for real-time interaction. However, for global team members with high spatial boundaries and high temporal boundaries (e.g., different cities in different time zones), asynchronous communication technologies such as e-mail and web software provide a way to interact intermittently. Using social network data from 625 team members (representing 5986 pairs) across 137 global teams in a multi-national semiconductor firm, we explore the impact of spatial and temporal boundaries on coordination delay. We also illustrate how member awareness can reduce coordination delay, thus increasing the likelihood of better global team performance.

description: The purpose of the study was to examine the relationship between the main components of role play, according to Vygotsky (object substitution, idea of play, play interaction), and executive functions (working memory, inhibition, cognitive flexibility, planning) in preschool age. The study involved 56 children, 5 to 6 years old (29 boys and 27 girls). Play observation was conducted in small groups of two to three children in a playroom in kindergarten with special multifunctional “open” materials. The results revealed significant relationships between planning and the role-play components associated with the stability and level of the play idea, object and space substitution, and the organizing interaction in play. Comparison of the play components in children with low and high levels of executive function showed that children with a high level had higher positional substitution, detalization of idea (the extent to which a child reveals their idea to partners) in play, and a higher general play level than children with low executive function levels. Thus, the study shows that high levels of executive function are related with high levels of play, and this makes play an effective tool for the development of executive functions.
Crowded trades, market clustering, and price instability

description: Crowded trades by similarly trading peers influence the dynamics of asset prices, possibly creating systemic risk. We propose a market clustering measure using granular trading data. For each stock the clustering measure captures the degree of trading overlap among any two investors in that stock. We investigate the effect of crowded trades on stock price stability and show that market clustering has a causal effect on the properties of the tails of the stock return distribution, particularly the positive tail, even after controlling for commonly considered risk drivers. Reduced investor pool diversity could thus negatively affect stock price stability.

description: Presently, the term transition radiation tends to denote a somewhat different physical phenomenon than the original transition radiation discovered by J. E. Lilienfeld in 1919, and re-employed in different forms again in 1953 and 1971. Lilienfeld transition radiation is a subtle kind of radiation with distinctive properties that may often be unexpected in prospect, yet is intuitive and readily understood in retrospect. This paper distinguishes in clear terms between the different kinds of transition radiation, and shows its link to modern apparatus such as possible applications in the area of x-ray microscopy, microholography, and the free electron laser .
