description: The method of asymptotic normalization coefficients is a standard approach for studies of two-body non-resonant radiative capture processes in nuclear astrophysics. This method suggests a fully analytical description of the radiative capture cross section in the low-energy region of the astrophysical interest. We demonstrate how this method can be generalized to the case of three-body $2p$ radiative captures. It was found that an essential feature of this process is the highly correlated nature of the capture. This reflects the complexity of three-body Coulomb continuum problem. Radiative capture $^{15}$O+$p$+$p \rightarrow ^{\,17}$Ne+$γ$ is considered as an illustration.

An ascending HNN extension of a free group inside SL(2,C)

description: We give an example of a subgroup of SL(2,C) which is a strictly ascending HNN extension of a non-abelian finitely generated free group F. In particular, we exhibit a free group F in SL(2,C) of rank 6 which is conjugate to a proper subgroup of itself. This answers positively a question of Drutu and Sapir. The main ingredient in our construction is a specific finite volume (noncompact) hyperbolic 3-manifold M which is a surface bundle over the circle. In particular, most of F comes from the fundamental group of a surface fiber. A key feature of M is that there is an element of its fundamental group with an eigenvalue which is the square root of a rational integer. We also use the Bass-Serre tree of a field with a discrete valuation to show that the group F we construct is actually free.

description: Neutrino-driven convection plays a crucial role in the development of core-collapse supernova (CCSN) explosions. However, the complex mechanism that triggers the shock revival and the subsequent explosion has remained inscrutable for many decades. Multidimensional simulations suggest that the growth of fluid instabilities and the development of turbulent convection will determine the morphology of the explosion. We have performed 3D simulations using spherical-polar coordinates covering a reduced angular extent (90 degree computational domain), and with angular resolutions of 2 degrees, 1 degree, 1/2 degree, and 1/4 degree, to study the development of turbulence in core-collapse supernova explosions on a time scale of order 100 ms. We have employed the multi-physics Chimera code that includes detailed nuclear physics and spectral neutrino transport. Coarse resolution models do not develop an inertial range, presumably due to the bottleneck effect, such that the energy is prevented from cascading down to small scales and tends to accumulate at large scales. High-resolution models instead, start to recover the k^{-5/3} scaling of Kolmogorov's theory. Stochasticity and few simulation samples limit our ability to predict the development of explosions. Over the simulated time period, our models show no clear trend in improving (or diminishing) conditions for explosion as the angular resolution is increased. However, we find that turbulence provides an effective pressure behind the shock (approx. 40 - 50 % of the thermal pressure), which can contribute to the shock revival and be conducive for the development of the explosion. Finally, we show that the turbulent energy power spectrum of reduced angular extent and full 4 pi models are consistent, thus indicating that a 90 degree computational domain is an adequate configuration to study the character of turbulence in CCSNe.

description: We investigate the strongly correlated ion dynamics and the degree of coupling achievable in the evolution of freely expanding ultracold neutral plasmas. We demonstrate that the ionic Coulomb coupling parameter $Γ_{\rm i}$ increases considerably in later stages of the expansion, reaching the strongly coupled regime despite the well-known initial drop of $Γ_{\rm i}$ to order unity due to disorder-induced heating. Furthermore, we formulate a suitable measure of correlation and show th at $Γ_{\rm i}$ calculated from the ionic temperature and density reflects the degree of order in the system if it is sufficiently close to a quasisteady state. At later times, however, the expansion of the plasma cloud becomes faster than the relaxation of correlations, and the system does not reach thermodynamic equilibrium anymore.

description: Motivated by theoretical predictions that first stars were predominantly very massive, we investigate the physics of the transition from an early epoch dominated by massive Pop III stars to a later epoch dominated by familiar low-mass Pop II/I stars by means of a numerically-generated catalogue of dark matter halos coupled with a self-consistent treatment of chemical and radiative feedback. Depending on the strength of the chemical feedback, Pop III stars can contribute a substantial fraction (several percent) of the cosmic star formation activity even at moderate redshifts, z = 5. We find that the three z = 10 sources tentatively detected in NICMOS UDFs should be powered by Pop III stars, if these are massive; however, this scenario fails to reproduce the derived WMAP electron scattering optical depth. Instead, both the UDFs and WMAP constraints can be fulfilled if stars at any time form with a more standard, slightly top-heavy, Larson IMF in the range 1 Msun < M < 100 Msun.

description: When measuring quantum spins at two or more different times, the later measurements are affected by measurement backaction occurring due to the earlier measurements. This makes the measurement of temporal quantum correlation functions challenging. In this paper, I propose a measurement protocol that mitigates the effect of measurement backaction by exploiting spin selection rules. I show that, under suitable conditions, the effect of measurement backaction on two-time quantum correlations becomes negligible when probing a system consisting of spins with large spin quantum numbers $l\gg s$ by coupling it to a spin-$s$ ancilla degree of freedom. A potential application of such a measurement protocol is the probing of an array of Bose-Einstein condensates by light.

description: The excitation function for the $pd\rightarrow$ $d p π^{0}$ reaction has been measured by WASA-at-COSY experiment with the aim of searching for $^{3}\hspace{-0.03cm}\mbox{He}$-$η$ mesic nuclei. The measurement in the vicinity of $η$ meson production was performed using a ramped proton beam. The data analysis and interpretation was carried out with the assumption that the $η$-mesic Helium decays via the formation of an intermediate N$^{*}$(1535) resonance. No direct signal of the $η$-mesic nucleus is observed in the excitation function. We determine a new improved upper limit for the total cross section for the bound state production and decay in the $pd\rightarrow$ $(^{3}\hspace{-0.03cm}\mbox{He}$-$η)_{bound} \rightarrow$ $d p π^{0}$ process. It varies between 13 nb to 24 nb for the bound state with width in the range $Γ\in (5,50)$ MeV.

description: In agricultural chains in the Netherlands, there are many initiatives to produce more sustainably. However, the growth of these chains is proceeding more slowly than is socially desirable. On the basis of nine case studies of niche products, this study attempts to provide an insight into where the obstacles to the growth of such chains lie. In addition, we examine the role of the chain parties and others (for example, the government) in removing these obstacles. In de Nederlandse landbouw zijn diverse initiatieven om in ketenverband duur& zamer te produceren. Echter, de groei van deze ketens is minder snel dan maatschappelijk gewenst is. Dit onderzoek wil op basis van negen cases van ni& cheproducten inzichtelijk maken waar de groeibelemmeringen in deze ketens zitten. Ook wordt ingegaan op de rol van de ketenpartijen en anderen (bijvoor& beeld de overheid) bij het oplossen van deze belemmeringen.

description: Microfluidic tools have recently made possible many advances in biological and biomedical research. Research in fields such as Physics, Engineering, Chemistry and Biology have combined to produce innovation in Microfluidics which has positively impacted diverse areas such as nucleotide sequencing, functional genomics, single-cell studies, single molecules assays and biomedical diagnostics. Among these areas, regenerative medicine and stem cells have benefited from Microfluidics since these tools have had a profound impact on their applications. In this study, we present a high-performance droplet-based system for transfecting individual human-induced pluripotent stem cells. We will demonstrate that this system has great efficiency in single cells and captured droplets, like other microfluidic methods but with lower cost. Moreover, this microfluidic approach can be associated with the PiggyBac transposase-based system to increase its transfection efficiency. Our results provide a starting point for subsequent applications in more complex transfection systems, single-cell differentiation interactions, cell subpopulations, cell therapy, among other potential applications.

description: Thirteen transitions within the ground 3d^2 configuration of Fe VII are identified in ultraviolet and optical spectra of the symbiotic star RR Telescopii obtained with the STIS instrument of the Hubble Space Telescope. The line fluxes are compared with theoretical data computed with the recent atomic data of K.A. Berrington et al., and high resolution optical spectra from VLT/UVES are used to identify blends. Seven branching ratios are measured, with three in good agreement with theory and one affected by blending. The lambda5277/lambda4943 branching ratio is discrepant by > 3 sigma, indicating errors in the atomic data for the lambda5277 line. A least-squares minimization scheme is used to simultaneously derive the temperature, T, and density, N_e, of the RR Tel nebula, and the interstellar extinction, E(B-V), towards RR Tel from the complete set of emission lines. The derived values are: log T/K = 4.50 +/- 0.23, log N_e/cm^-3=7.25 +/- 0.05, and E(B-V)<0.27. The extinction is not well-constrained by the Fe VII lines, but is consistent with the more accurate value E(B-V)=0.109^{+0.052}_{-0.059} derived here from the Ne V lambda2974/lambda1574 ratio in the STIS spectrum. Large differences between the K.A. Berrington et al. electron excitation data and the earlier F.P. Keenan & P.H. Norrington data-set are demonstrated, and the latter is shown to give worse agreement with observations.

description: To cope with globalisation and other changes in the industry, in the last 20 years the Dutch Ministry of Agriculture has reorganised its system for education, extension and research considerably. It moved away from the concept of a linear process of innovation to that of an agro-innovation system. This paper describes the main changes. The paper argues that an evaluation of the changes is problematic. In an open economy where a large part of the public investments are targeted to reduce negative externalities of production (especially on environmental impact), a part of productivity is due to persons leaving the sector and income in farming is dependent on value added processes in its multinational cooperatives, causes and effects are hard to disentangle. The changes in the education, extension and research system cannot easily be evaluated by productivity analyses. Most research on this topic tries to develop methods for monitoring and evaluation from social learning or public administration.

Modulation of versican expression by smooth muscle cells and myofibroblasts in cardiovascular disease
Creators: name: McDonald, Paul Christopher
Publisher: name: University of British Columbia
Year: 2009

description: Aberrant accumulation of proteoglycans, particularly versican, is a hallmark of vascular lesions and is potentially important in the development of myxomatous cardiac valve lesions. My overarching hypothesis is that the dysregulation of proteoglycan expression plays an important role in the pathogenesis of accelerated vascular disease and valvular heart disease. I tested three specific hypotheses relating to this overarching framework. First, that the overexpression of versican by smooth muscle cells (SMCs) is due to modulation of its expression by specific molecules present within the tissue microenvironment. Second, that versican is spatially associated with modified lipoproteins in human atheromatous disease. Third, that the exposure of cardiac valves to certain anorexigens (appetite suppressants) produces a proteoglycan-rich lesion morphologically distinct from lesions characterizing other valve diseases and related to the dysregulation of versican expression by myofibroblasts (MFBs). To address the first hypothesis, growth factor-mediated modulation of versican expression by rat aortic SMCs was examined. Treatment of SMCs with either epidermal growth factor (EGF) or insulin-like growth factor-I (IGF-I) significantly upregulated versican mRNA levels and increased core protein expression. Stimulation of SMCs with a combination of EGF and IGF-I further increased versican expression. The oxidative status of lipoproteins present in coronary arteries from human heart allografts and their localization relative to versican and vessel wall cells were examined to address the second hypothesis. Lipoproteins in mild and severe lesions were oxidatively modified, although certain forms of oxidative modification only appeared in severe lesions. The oxidized lipoproteins were often associated with versican and intimal SMCs. The third hypothesis was addressed by examining the geometric and compositional characteristics of normal and diseased heart valves. Valves excised from patients exposed to anorexigens exhibited a glycosaminoglycan-rich lesion distinct from lesions characterizing other myxomatous valve diseases. The myxomatous process was present in both the valve onlays and the valve proper. Myxomatous regions were rich in versican and MFBs cultured from human cardiac valve tissue expressed versican. In summary, these data provide key insights into the modulation of versican expression and lay the groundwork for future experiments aimed at further understanding the regulation of versican expression and development of potential novel therapies for the treatment of cardiovascular disorders.

description: The time-convolutionless (TCL) projection operator technique allows a systematic analysis of the non-Markovian quantum dynamics of open systems. We introduce a class of projection superoperators which project the states of the total system onto certain correlated system-environment states. It is shown that the application of the TCL technique to this class of correlated superoperators enables the non-perturbative treatment of the dynamics of system-environment models for which the standard approach fails in any finite order of the coupling strength. We demonstrate further that the correlated superoperators correspond to the idea of a best guess of conditional quantum expectations which is determined by a suitable Hilbert space average. The general approach is illustrated by means of the model of a spin which interacts through randomly distributed couplings with a finite reservoir consisting of two energy bands. Extensive numerical simulations of the full Schroedinger equation of the model reveal the power and efficiency of the method.

description: Over the past 50 years public agricultural research has contributed enormously to humanity, enabling the supply of food to grow faster than demand in spite of a rapidly growing population, income growth, and shrinking natural resources. Nonetheless, in many countries we see waning public support for agricultural R&D, especially in Africa, a diversion of research resources from farm productivity towards other agendas, and early warning signs of a slowdown in agricultural productivity. The world has continued to collectively underinvest in agricultural R&D because of domestic and international market failures associated with appropriability problems. Governments have failed to effectively address these problems, often doing too little, too late. This tragedy of the international commons may be getting worse. In the past, developing countries benefited considerably from technological spillovers from developed countries, but because of changes occurring in developed countries, spillovers from developed countries may not be available to developing countries in the same ways or to the same extent. In this article, the factors contributing to persistent global underinvestment in agricultural R&D are described from a developing-country perspective, estimates of agricultural R&D spending trends are presented, and incentive mechanisms for increasing rates of investment in agricultural R&D are described and assessed.

On the specific heat of a fermionic atomic cloud in the unitary regime
Creators: name: Bulgac, Aurel

Subjects: subject: Statistical Mechanics (cond-mat.stat-mech)

description: In the unitary regime, when the scattering amplitude greatly exceeds in magnitude the average inter-particle separation, and below the critical temperature thermal properties of an atomic fermionic cloud are governed by the collective modes, specifically the Bogoliubov-Anderson sound modes. The specific heat of an atomic cloud in a elongated trap in particular has a rather compex temperature dependence, which changes from an exponential behavior at very low temperatures ($T\ll\hbarω_{||}$), to $\propto T$ for $\hbarω_{||}\ll T \ll \hbarω_\perp$ and then continuosly to $\propto T^4$ at temperatures just below the critical temperature, when the surface modes play a dominant role. Only the low ($\hbarω_{||} \ll T \ll \hbarω_\perp$) and high ($\hbarω_\perp \ll T < T_c$) temperature power laws are well defined. For the intermediate temperatures one can introduce at most a gradually increasing with temperature exponent.

description: The electronic structure of Si(111)-(6x6)Au surface covered with submonolayer amount of Pb is investigated using scanning tunneling spectroscopy. Already in small islands of Pb with thickness of 1 ML Pb$_{(111)}$ and with the diameter of only about 2 nm we detected the quantized electronic state with energy 0.55 eV below the Fermi level. Similarly, the I(V) characteristics made for the Si(111)-(6x6)Au surface reveal a localized energy state 0.3 eV below the Fermi level. These energies result from fitting of the theoretical curves to the experimental data. The calculations are based on tight binding Hubbard model. The theoretical calculations clearly show prominent modification of the I(V) curve due to variation of electronic and topographic properties of the STM tip apex.

description: Thin-film lithium niobate on insulator (LNOI) has emerged as a superior integrated-photonics platform for linear, nonlinear, and electro-optics. Here we combine quasi-phase-matching, dispersion engineering, and tight mode confinement to realize nonlinear parametric processes with both high efficiency and wide wavelength tunability. On a millimeter-long, Z-cut LNOI waveguide, we demonstrate ultra-efficient ($1900\pm500 \% $W$^{-1}$cm$^{-2}$) and highly tunable (-1.71 nm/K) second-harmonic generation from 1530 to 1583 nm by type-0 quasi-phase-matching. Our technique is applicable to optical harmonic generation, quantum light sources, frequency conversion, and many other photonic information processing across visible to mid-IR spectral bands.

description: Economic expansion revaluates continuously the economic and social role of agriculture. Population explosion in the world generates continuously growing demand on foods and industrial raw materials. Supply of increased demand is supported by R&D, at the same time using results of it polarizes the economies. In the agriculture the technical development (i.e. development of technical, technological and biological basis of production, chemicalization, education of human resources) produces potential for increasing efficiency of production. The first period of technical development serves characteristically the supply of quantitative demand, but after it reached the equilibrium of supply and demand, then qualitative development becomes aim. Development releases labour, which can be positive or negative externalities for society. Later on demand of sustainability appears, with its ecological, economical and social aspects. Based on experiences of Hungarian model realized in the 1970s and 1980s, the paper examines how technical development is realizable successfully in the frame of segmented farm structure, how competitive and efficient farming could be done in this structure, keeping in mind in advantages of large farms. The paper analyses the competitiveness of virtual large-scale farms (which are based on cooperation and coordination of small farms), and confirms their efficiency with model examinations. Research was supported by the K 63231 theme of the Hungarian Research Fund (OTKA).

description: This study investigated the cost structure of the floriculture industry in the United States. Economies of scale and input elasticities were estimated with a normalized quadratic cost function. Results suggest that economies of scale exist in the floriculture industry. As producers become large and more automated, they have a cost advantage relative to smaller producers who are producing the same output product mix. The existence of economies of scale suggests that average grower size can increase in the future as growers increase in size to take advantage of cost efficiencies.

description: Public health experts are concerned about the diminishing efficacy of antibiotics. Some have called for a ban on growth-promoting antibiotics in animal agriculture. This study identifies the contribution of growth-promoting antibiotics in the grower/finisher phase of U.S. pork production. With National Animal Health Monitoring System swine data, relationships are estimated between growth-promoting antibiotic use and productivity. Results indicate improvements in average daily gain (0.5%), feed conversion ratio (1.1%), and mortality rate (reduced 0.22 percentage points); these productivity improvements translate into a profitability gain of $0.59 per pig marketed, or an improvement of 9% in net profits associated with growth promotion antibiotics.

description: With this work we elaborate on the physics of quantum noise in thermal equilibrium and in stationary non-equilibrium. Starting out from the celebrated quantum fluctuation-dissipation theorem we discuss some important consequences that must hold for open, dissipative quantum systems in thermal equilibrium. The issue of quantum dissipation is exemplified with the fundamental problem of a damped harmonic quantum oscillator. The role of quantum fluctuations is discussed in the context of both, the nonlinear generalized quantum Langevin equation and the path integral approach. We discuss the consequences of the time-reversal symmetry for an open dissipative quantum dynamics and, furthermore, point to a series of subtleties and possible pitfalls. The path integral methodology is applied to the decay of metastable states assisted by quantum Brownian noise.

Massive Stellar Content of Giant HII Regions in M 33 and M 101
Creators: name: Pellerin, Anne
Publisher: name: arXiv
Year: 2005
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: Far-ultraviolet (900-1200A) spectral synthesis of nine giant extragalactic HII regions in M 33 and M 101 is performed to study their massive stellar content. Several parameters are quantified, predicted, and compared to the literature: age, stellar mass, IMF slope, number of O-type and Wolf-Rayet stars, Halpha and 5500A continuum fluxes. The results of this particular technique are consistent with other methods and observations. This work shows that a total stellar mass of a few 10^3 Msun is needed to populate the IMF bins well enough at high masses to obtain accurate results from the spectral synthesis technique in the far-ultraviolet. A flat IMF slope seems to characterize better the stellar line profiles of these objects, which is likely the first sign of a small number statistic effect on the IMF. Finally, the HII region NGC 5461 is identified as a good candidate for hosting a second generation of stars, not yet seen at far-ultraviolet wavelengths.

EMPLOYMENT IN THE DIGITAL ECONOMY

description: The development of the digital economy does not necessarily reduce the size of employment, but rather the substitution effect and the suppression of the substitution effect co-exist, resulting in the digital economy not reducing employment. However, the labor market is characterized by a combination of technological unemployment and competition for talent. On the one hand, technological unemployment includes not only low-education groups but also highly educated people; on the other hand, the competition for talent is not limited to highly educated people, but also to some low-education groups. This has a definite impact on current education. This paper focuses on the substitution effects of the digital economy on employment, and also explains the two-way influence mechanism between the digital economy and education in the context of new employment.
The Epidemic-Driven Collapse in a System with Limited Economic Resource

description: We consider a possibility of socioeconomic collapse caused by the spread of epidemic in a basic dynamical model with negative feedback between the infected population size and a formal collective economic resource. The epidemic-resource coupling is supposed to be of activation type, with the recovery rate governed by the Arrhenius-like law and resource playing the role of temperature. Such a coupling can result in the collapsing effect opposite to thermal explosion because of the limited resource. In this case, the system can no longer stabilize and return to the stable pre- or post-epidemic states. We demonstrate that such a collapse can partially be mitigated by means of a negative resource or debt.

description: We study metal abundances in the z=0.9313 damped Lya system observed in the two lines-of-sight, A and B, toward the gravitationally-lensed double QSO HE0512-3329. Spatially resolved STIS spectra constrain the neutral-gas column density to be LogN(HI)=20.5 in both Aand B. UVES spectra (spectral resolution FWHM=9.8 km/s) show, in contrast, significant line-of-sight differences in the column densities of MnII and FeII; these are not due to observational systematics. We find that [Mn/H]=-1.44 and [Fe/H]=-1.52 in damped Lya system A, while [Mn/H]=-0.98 and [Fe/H]>-1.32, and possibly as high as [Fe/H] approx. -1 in damped Lya system B. A careful assessment of possible systematic errors leads us to conclude that these transverse differences are significant at a 5 sigma level or greater. Although nucleosynthesis effects may also be at play, we favor differential dust-depletion as the main mechanism producing the observed abundance gradient. The transverse separation is 5 kpc at the redshift of the absorber, which is also likely to be the lensing galaxy. The derived abundances therefore probe two opposite sides of a single galaxy hosting both damped Lya systems. This is the first time firm abundance constraints have been obtained for a single damped system probed by two lines-of-sight. The significance of this finding for the cosmic evolution of metals is discussed.

description: The paper investigates the selection mechanisms of rural development policy using a survey among farmers in the Southern Great Plain region characterising by the high level of unemployment and strong agricultural background. We focus on the farmers social-economic characteristics explaining of success of application for rural development subsidies employing selection and count models. Estimations show that the higher educated and older farmers more likely apply for rural supports, whilst the share of less favoured land affects negatively on the application for subsidy. We found selection bias in the success of application. Results imply that farmers with less favoured land less likely receive, whilst higher educated and older farmers more likely receive rural supports. Similarly, the share of less favoured area affects negatively for number of successful application both in terms of type and number of subsidy
