description: The B -> X_s l+ l- decay rate is known at the next-to-next-to-leading order in QCD. It is proportional to alpha_em (mu)^2 and has a +- 4% scale uncertainty before including the O(alpha_em log(M_W^2/m_b^2)) electromagnetic corrections. We evaluate these corrections and confirm the earlier findings of Bobeth et al. >. Furthermore, we complete the calculation of logarithmically enhanced electromagnetic effects by including also QED corrections to the matrix elements of four-fermion operators. Such corrections contain a collinear logarithm log(m_b^2/m_l^2) that survives integration over the low dilepton invariant mass region 1 GeV^2 < q^2 < 6 GeV^2 and enhances the integrated decay rate in this domain. For the low-q^2 integrated branching ratio in the muonic case, we find B (B -> X_s mu^+mu^-) = (1.59 +- 0.11) 10^(-6), where the error includes the parametric and perturbative uncertainties only. For B (B -> X_s e^+e^-), in the current BaBar and Belle setups, the logarithm of the lepton mass gets replaced by angular cut parameters and the integrated branching ratio for the electrons is expected to be close to that for the muons.

The Demographics of Long-Period Comets

Year: 2005
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: The absolute magnitude and perihelion distributions of long-period comets are derived, using data from the Lincoln Near-Earth Asteroid Research (LINEAR) survey. The results are surprising in three ways. Firstly, the flux of comets through the inner solar system is much lower than some previous estimates. Secondly, the expected rise in comet numbers to larger perihelia is not seen. Thirdly, the number of comets per unit absolute magnitude does not significantly rise to fainter magnitudes. These results imply that the Oort cloud contains many fewer comets than some previous estimates, that small long-period comets collide with the Earth too infrequently to be a plausible source of Tunguska-style impacts, and that some physical process must have prevented small icy planetesmals from reaching the Oort cloud, or have rendered them unobservable. A tight limit is placed on the space density of interstellar comets, but the predicted space density is lower still. The number of long-period comets that will be discovered by telescopes such as SkyMapper, Pan-Starrs and LSST is predicted, and the optimum observing strategy discussed.

description: Dairy producers have focused on increasing production and ignored the implications this may have on resource allocation efficiency. Averaged comparative figures are used to justify the production message but these cannot distinguish the point at which diminishing profitability from additional inputs will occur. Resource allocation using Linear Programming allows the effects of a simultaneous variation in resources to be revealed. Dairy production profitability is optimised where technical and biological efficiency combine to provide the best economic and coincidentally, environmental outcomes.

description: In this paper the format of a Social Accounting Matrix (SAM) for use as a database for the Computable General Equilibrium (CGE) modelling of agricultural policy reform in South Africa is detailed. It is shown that the published South African SAMs impose limitations upon their suitability as databases for CGE models, but that they can be readily modified. An additional benefit of a SAM is its use as a framework for the specification of the behavioural relationships necessary to the development of a model. Finally, a Macro SAM for 1993 is reported and the proposed disaggregation of the agricultural sector is identified.

description: The Rotterdam model is used to estimate a demand system for South African (SA) beef, chicken, mutton and pork during 1971-1995 and identify the potential impacts on demand for these meat types of a Free Trade Agreement (FTA) between SA and the European Union. Conditional cross-price Slutsky elasticity estimates show that for a given 1% change in each meat price under an FTA, the beef price change would have the largest impact on consumption of the other meats. The net effect of the FTA would depend on the extent to which different meat prices fall if meat imports increase. Import competition may be felt particularly from poultry imports as most of SA beef imports are of a low quality.

Year: 2005

subject: FOS: Physical sciences

description: Fourier transform power spectra of major axis cuts in V and Halpha images were made for a sample of 9 irregular galaxies. These power spectra reveal structure over a wide range of scales. For 6 of the galaxies the power spectrum slopes at intermediate scales (1-400 pc) in the V-band images range from -1.3 to -1.5. The similarity of slopes suggests that the same processes are structuring these systems. These slopes are slightly shallower than what is observed in other galaxies in HI, molecular emission, dust extinction, and optical light. Three of the galaxies have flat power spectra like noise from the sky; these three galaxies are relatively indistinct in the direct images. The power spectrum slope for Halpha steepens with increasing star formation rate, ranging from a shallow value comparable to the noise at low rates to a steep value with a slope of -1.5 at high rates. This change reflects the increasing areal filling factor of Halpha emission with increasing star formation rate, and an apparently universal slope inside the Halpha regions that is comparable to that for Kolmogorov turbulence. The power spectrum of HI in one galaxy has a steeper power law, with a slope of -2.9. The fact that the power laws of star formation are about the same for dwarf galaxies and giant spiral galaxies suggests the microscopic processes are the same, independent of spiral density waves and galaxy size.

description: Two Stage Least Squares and principal component analysis were used to estimate the export demand and supply of South African (SA) fresh oranges in the United Kingdom (UK) during 1976-1993. Export demand was negatively related to the SA fresh orange price relative to the price of fresh oranges from Israel, and positively related to lagged orange exports (consumer brand loyalty proxy). Export supply was positively related to lagged net export realisation price relative to domestic orange price, the SA fresh orange price in the UK relative to the SA fresh orange price in France, lagged exports (export orientation), and supply shocks. The relative price elasticity of export demand was inelastic in both the short- and long-run, indicating that Capespan International and other future exporters may need to diversify fresh orange exports to alternative export markets to increase real revenue. Long-run export supply was inelastic with respect to relative price, implying that if SA fresh orange exports are included in a Free Trade Agreement with the EU, they are unlikely to have a marked adverse affect on EU fresh orange producers.

The results are compared to a break-up diagram of shearless invariant curves. The existence of meanders (invariant tori that are not graphs) is demonstrated numerically for both odd and even period reconnection for certain regions in parameter space, and some of the implications on transport are discussed.

description: The true value of irrigation water in the Olifants river irrigation system is determined using a static deterministic linear programming model. This paper illustrates that a water market will generate price signals which will reflect the true scarcity of water. If the water market is left to operate pareto optimality will be reached and the general welfare of the nation will increase. What is more, water which is a true scarce resource in South Africa will be used more effectively.

description: Chandra observations of the merging galaxy cluster A520 reveal a prominent bow shock with M=2.1+0.4-0.3. This is only the second clear example of a substantially supersonic merger shock front in clusters. Comparison of the X-ray image with that of the previously known radio halo reveals a coincidence of the leading edge of the halo with the bow shock, offering an interesting experimental setup for determining the role of shocks in the radio halo generation. The halo in A520 apparently consists of two spatially distinct parts, the main turbulence-driven component and a cap-like forward structure related to the shock, where the latter may provide pre-energized electrons for subsequent turbulent re-acceleration. The radio edge may be caused by electron acceleration by the shock. If so, the synchrotron spectrum should have a slope of 1.2 right behind the edge with quick steepening further away from the edge. Alternatively, if shocks are inefficient accelerators, the radio edge may be explained by an increase in the magnetic field and density of pre-existing relativistic electrons due to gas compression. In the latter model, there should be radio emission in front of the shock with the same spectrum as that behind it, but 10-20 times fainter. If future sensitive radio measurements do not find such pre-shock emission, then the electrons are indeed accelerated (or re-accelerated) by the shock, and one will be able to determine its acceleration efficiency. We also propose a method to estimate the magnetic field strength behind the shock, based on measuring the dependence of the radio spectral slope upon the distance from the shock. In addition, the radio edge provides a way to constrain the diffusion speed of the relativistic electrons.

description: This study was aimed at examining the role of Women farmers’ cooperative Societies in Agricultural Production in Bauchi Local Government Area of Bauchi State Nigeria. A total of eighty (80) women farmers were randomly selected from eight Cooperative societies which represent 50% of all registered and viable Cooperative Societies in the study area. Data were collected using well-structured pre-tested interview schedules, and analysed by means of descriptive statistics (frequency distribution, percentages and means). The results indicated that women Cooperative Societies in the study area were engaged in agricultural activities, such as land clearance (62.5%), planting and transplanting (62.5%) weeding (40%), fertilizer application (75%), food processing (87.5%), food storage (95%) and animal production and management (94%) respectively. The average land size of the respondents was 1.3 hectare. Constraints to their development efforts included inadequacy of finance; lack of training of their members, inadequate farm implements and lack of suitable machines for Women farmer’s use. Government should provide soft and medium term loan to women cooperative societies. Extension staff should make women cooperative societies as a target group for quick delivery of extension services. Apparently technologies for Women farmers should be made available and affordable to all women farmers particularly members of Cooperative Societies.

description: Measurements of polarization-dependent soft x-ray absorption reveal that the electronic states determining the low-energy excitations of Na$_{x}$CoO$_2$ have predominantly $a_{1g}$ symmetry with significant O $2p$ character. A large transfer of spectral weight observed in O $1s$ x-ray absorption provides spectral evidence for strong electron correlations in the layered cobaltates. Comparing Co $2p$ x-ray absorption with calculations based on a cluster model, we conclude that Na$_{x}$CoO$_2$ exhibits a charge-transfer electronic character rather than a Mott-Hubbard character.

description: It is demonstrated theoretically that the absorptivity of bulk shear sagittal waves by an ultra-thin layer of viscous fluid between two different elastic media has a strong maximum (in some cases as good as 100%) at an optimal layer thickness. This thickness is usually much smaller than the penetration depths and lengths of transverse and longitudinal waves in the fluid. The angular dependencies of the absorptivity are demonstrated to have significant and unusual structure near critical angles of incidence. The effect of non-Newtonian properties and non-uniformities of the fluid layer on the absorptivity is also investigated. In particular, it is shown that the absorption in a thin layer of viscous fluid is much more sensitive to non-zero relaxation time(s) in the fluid layer than the absorption at an isolated solid-fluid interface.

description: This paper introduces a new method for discretizing and solving integral equation formulations of Maxwell's equations which achieves spectral accuracy for smooth surfaces. The approach is based on a hybrid Nyström-collocation method using Chebyshev polynomials to expand the unknown current densities over curvilinear quadrilateral surface patches. As an example, the proposed strategy is applied the to Magnetic Field Integral Equation (MFIE) and the N-Müller formulation for scattering from metallic and dielectric objects, respectively. The convergence is studied for several different geometries, including spheres, cubes, and complex NURBS geometries imported from CAD software, and the results are compared against a commercial Method-of-Moments solver using RWG basis functions.

Participation in online environments : its relationship to adolescent self-concept
Creators: name: Law, Danielle M.
Publisher: name: University of British Columbia
Year: 2009

description: The purpose of this study was to investigate the relationship between online participation and adolescent self-concept. Specifically, this study examined (a) how online participation differed across five online venues (Multi-player Online Role Playing Games, Chatrooms, Instant Messaging, Email, and Newsgroups/Forums), as a function of gender and age, (b) how subjective importance of online venues and the nature of online relationships influenced domain and general self-conceptions, (c) whether online selfconceptions moderate the relationship between domains of self-concept and global selfworth, and (d) whether online self-conceptions mediate the relationship between domain self-conceptions and global self-worth. A total of 363 (184 males, and 179 females) students, whose ages ranged from 11 to 19 years of age, participated in this study. Overall, males used Multi-player Online Role Playing Games, Chatrooms, and Newsgroups/Forums more than females, while females tended to use Email and IM slightly more than males. With regards to Internet participation and self-concept, significant main and interaction effects were found; however, these effects varied according to the online venue, the domain of self-concept, and with whom the adolescents were participating. Additionally, moderation and mediation effects were confirmed for some online venues, thus suggesting that a relationship between online participation and self-concept exists. Several recommendations for future research are discussed.

description: Network representation learning (NRL) plays a vital role in a variety of tasks such as node classification and link prediction. It aims to learn low-dimensional vector representations for nodes based on network structures or node attributes. While embedding techniques on complete networks have been intensively studied, in real-world applications, it is still a challenging task to collect complete networks. To bridge the gap, in this paper, we propose a Deep Incomplete Network Embedding method, namely DINE. Specifically, we first complete the missing part including both nodes and edges in a partially observable network by using the expectation-maximization framework. To improve the embedding performance, we consider both network structures and node attributes to learn node representations. Empirically, we evaluate DINE over three networks on multi-label classification and link prediction tasks. The results demonstrate the superiority of our proposed approach compared against state-of-the-art baselines.

description: In this work, we study the relativistic quantum kinetic equations in 2+1 dimensions from Wigner function formalism by carrying out a systematic semi-classical expansion up to $\hbar$ order. The derived equations allow us to explore interesting transport phenomena in 2+1 dimensions. Within this framework, the parity-odd transport current induced by the external electromagnetic field is self-consistently derived. We also examine the dynamical mass generation by implementing four-fermion interaction with mean-field approximation. In this case, a new kind of transport current is found to be induced by the gradient of the mean-field condensate. Finally, we also utilize this framework to study the dynamical mass generation in an external magnetic field for the 2+1 dimensional system under equilibrium.

description: We present experimental results, as well as numerical simulations, for the transverse velocity distribution of ions stored in an electrostatic ion beam trap. The measurements indicate that the transverse velocity spread is about 1% of the longitudinal velocity, and that the ions fill the whole transverse stable phase space. We also demonstrate that ion losses from the trap due to multiple scattering with molecules from the residual gas is an important factor limiting the lifetime of the beam.

description: Research throughout the developing world has shown a potentially strong relationship between agro-industrial investments and growth in smallholder agriculture and poverty reduction. This paper suggests that agro-industrial investments, if properly structured to relate to smallholder producers, can play a very important role in rural poverty reduction strategies in Mozambique. Current agro-industrial investments in the country demonstrate various degrees of connectedness with rural households. The choice of how, and how closely, to relate to smallholders is determined by the characteristics of the commodity, by the physical, political, and economic environment in which the investment takes place, and by the knowledge, skills, experience, and preferences of the smallholders and of the investors and company management. Given the breadth of factors involved, different approaches can emerge under apparently very similar circumstances, each with differing implications for rural poverty reduction. Therefore, knowledge of the likely effects of alternative investment options in the food and fiber industries on rural incomes and firm profits becomes an important asset in the design of rural poverty reduction strategies.

description: Chromospheric activities prior to solar flares provide important clues to solar flare initiation, but are as yet poorly understood. We report a significant and rapid H$α$ line broadening before the solar flare SOL2011-09-29T18:08, that was detected using the unprecedented high-resolution H$α$ imaging spectroscopy with the Fast Imaging Solar Spectrograph (FISS) installed on the 1.6 m New Solar Telescope (NST) at Big Bear Solar Observatory.The strong H$α$ broadening extends as a blue excursion up to -4.5 A and as a red excursion up to 2.0 A, which implies a mixture of velocities in the range of -130 km/s to 38 km/s by applying the cloud model, comparable to the highest chromospheric motions reported before. The H$α$ blueshifted broadening lasts for about 4 minutes, and is temporally and spatially correlated with the start of a rising filament, which is later associated with the main phase of the flare as detected by the Atmosphere Imaging Assembly (AIA) onboard Solar Dynamics Observatory (SDO). The potential importance of this H$α$ blueshifted broadening as a preflare chromospheric activity is briefly discussed within the context of the two-step eruption model.

Novel Gravity Probe B Gravitational Wave Detection

description: The Gravity Probe B (GP-B) satellite experiment will measure the precession of on-board gyroscopes to extraordinary accuracy. Such precessions are predicted by General Relativity (GR), and one component of this precession is the `frame-dragging' or Lense-Thirring effect, which is caused by the rotation of the earth, and the other is the geodetic effect. A new theory of gravity predicts, however, a second and much larger `frame-dragging' or vorticity induced spin precession. This spin precession component will also display the effects of novel gravitational waves which are predicted by the new theory of gravity, and which have already been seen in several experiments. The magnitude and signature of these gravitational wave induced precession effects is given for comparison with the GP-B experimental data.

description: Facial appearance matters in social networks. Individuals frequently make trait judgments from facial clues. Although these face-based impressions lack the evidence to determine validity, they are of vital importance, because they may relate to human network-based social behavior, such as seeking certain individuals for help, advice, dating, and cooperation, and thus they may relate to centrality in social networks. However, little to no work has investigated the apparent facial traits that influence network centrality, despite the large amount of research on attributions of the central position including personality and behavior. In this paper, we examine whether perceived traits based on facial appearance affect network centrality by exploring the initial stage of social network formation in a first-year college residential area. We took face photos of participants who are freshmen living in the same residential area, and we asked them to nominate community members linking to different networks. We then collected facial perception data by requiring other participants to rate facial images for three main attributions: dominance, trustworthiness, and attractiveness. Meanwhile, we proposed a framework to discover how facial appearance affects social networks. Our results revealed that perceived facial traits were correlated with the network centrality and that they were indicative to predict the centrality of people in different networks. Our findings provide psychological evidence regarding the interaction between faces and network centrality. Our findings also offer insights in to a combination of psychological and social network techniques, and they highlight the function of facial bias in cuing and signaling social traits. To the best of our knowledge, we are the first to explore the influence of facial perception on centrality in social networks.

description: Wave-particle duality is one of the basic features of quantum mechanics, giving rise to the use of complex numbers in describing states of quantum systems, their dynamics, and interaction. Since the inception of quantum theory, it has been debated whether complex numbers are actually essential, or whether an alternative consistent formulation is possible using real numbers only. Here, we attack this long-standing problem both theoretically and experimentally, using the powerful tools of quantum resource theories. We show that - under reasonable assumptions - quantum states are easier to create and manipulate if they only have real elements. This gives an operational meaning to the resource theory of imaginarity. We identify and answer several important questions which include the state-conversion problem for all qubit states and all pure states of any dimension, and the approximate imaginarity distillation for all quantum states. As an application, we show that imaginarity plays a crucial role for state discrimination: there exist real quantum states which can be perfectly distinguished via local operations and classical communication, but which cannot be distinguished with any nonzero probability if one of the parties has no access to imaginarity. We confirm this phenomenon experimentally with linear optics, performing discrimination of different two-photon quantum states by local projective measurements. These results prove that complex numbers are an indispensable part of quantum mechanics.
