description: Here we report a comparison between reflectance spectroscopy of meteorites under asteroidal environment (high vacuum and temperature) and Main Belt and Near Earth Asteroids spectra. Focusing on the OH absorption feature around 3μm, we show that the asteroidal environment induces a reduction of depth and width of the band, as well as a shift of the reflectance minimum. We then decompose the OH feature into several components with a new model using Exponentially Modified Gaussians. Unlike previous studies, we confirme the link between these components, the aqueous alteration history and the amount of water molecules inside of the sample, using the shape of this spectral feature only. We then apply this deconvolution model to asteroids spectra which were obtained with a space-borne telescope and two space probes, and find a strong similarity with the components detected on meteorites, and among asteroids from a same type. Based on the conclusions drawn from our meteorites experiment, we suggest to use the 3-μm band as a tracer of the alteration history of the small bodies. Using the 3-μm band only, we show that Ryugu has been heavily altered by water, which is consistent with its parent body being covered with water ice, then went through a high temperature sequence, over 400°C. We also point out that the 3-μm band of Bennu shows signs of its newly discovered surface activity.

description: sing a theorem dubbed the {\em Multibreather Stabiliy Theorem} [Physica D 180 (2003) 235-255] we have obtained the stability properties of multibreathers in systems of coupled oscillators with on-site potentials, with an inhomogeneity. Analytical results are obtained for 2-site, 3-site breathers, multibreathers, phonobreathers and dark breathers. The inhomogeneity is considered both at the on-site potential and at the coupling terms. All the results have been checked numerically with excellent agreement. The main conclusion is that the introduction of a impurity does not alter the stability properties.

description: Agro-industries seem as an alternative to development to Sergipe semi-arid region that has to cope with the social and economic difficulties of local population and the climatic adversities as well. This study has the objective to identify the profile, management practices and the environmental management of agro-industries in Sergipe semi-arid region. Its data were collected both from secondary and primary sources such as structured personal interviews accomplished together with business owners and managers. From the universe of agro-industries of that region, a sample of forty-eight industries was selected, adopting non-proportional and non-probabilistic sampling criteria. As the main results of the study, it can be highlighted that the majority of these industries were of micro and small size and most were recently created, with predominance of manioc and diary products. In relation to management practices it was observed that there is no sanitary control of production, employment of temporary manpower in the harvest time, low sales competitiveness, and no costs control efficiently. Regarding the environmental management it was observed a low level of awareness related to the adoption of management practices that could guarantee a business sustained growth.

description: We study transport properties in boundary-driven asymmetric quantum spin chains given by $\mathit{XXZ}$ and $\mathit{XXX}$ Heisenberg models. Our approach exploits symmetry transformations in the Lindblad master equation associated to the dynamics of the systems. We describe the mathematical steps to build the unitary transformations related to the symmetry properties. For general target polarizations, we show the occurrence of the one-way street phenomenon for the energy current, namely, the energy current does not change in magnitude and direction as we invert the baths at the boundaries. We also analyze the spin current in some situations, and we prove the uniqueness of the steady state for all investigated cases. Our results, involving nontrivial properties of the energy flow, shall interest researchers working on the control and manipulation of quantum transport.

The overall objective of this work is to show the main efficiencies and institutional and organizational obstacles encountered in the core network that has been formed in that county. A key finding is that in that municipality of midsize and relevant generation of wealth for the state of São Paulo, there are small family farmers composing a network of local food security policy that has as a tool to foster the EAP (Acquisition Program Food) from the federal government. This will be demonstrated through an analysis of the characteristics of producers and the connections of the network of food safety policies.
Asymptotic behavior for nonlinear Schrödinger equations with critical time-decaying harmonic potential

description: Time-decaying harmonic oscillators yield dispersive estimates with weak decay, and change the threshold power of the nonlinearity between the short and the long range. In the non-critical case for the time-decaying harmonic oscillator, this threshold can be characterized by polynomial nonlinearities. However, in the critical case, it is difficult to characterize the threshold using only polynomial terms, and thus we use logarithmic nonlinear terms.

description: This study discusses an experience of a group of small lemon growers in a public irrigation project called Jaíba, partnering with a private company called Itacitrus, besides Codevasf (Development Company of the Valleys of San Francisco and Parnaiba). Because of the known difficulties of turning small properties into profitable units inside public irrigation projects in Brazil, the study aims to understand which were the elements that allowed the sustainable growth of the growers’ association. This paper identifies and analyses investments of each party involved in the partnership and their shared responsibilities. The method used is the in-depth case study, along with documental research and observation that allowed bringing up multiple and different variables over the phenomenon. The concept of networks is used along with social capital and marketing. The conclusions indicate that small family producers should acquire or develop product quality management techniques as well as trade competences. Secondly, trading companies should be able to develop long term partnerships with producers and governmental entities must evaluate whether critical competences are present as a way to drive public investments.

description: The Constitution of 1988 promotes cooperatives as privileged forms of organizing for the diggers. This paper analyses how diamond diggers from a district of Minas Gerais utilize the cooperative form, having as presupposition that there is an inherent conflict between the cooperative form and the organization of digging activities. This is a case study, for which documents were analyzed and also some of the board members of the cooperative, diamonds diggers members of the coop, local authorities and other relevant informants were interviewed. In this research Contingency Theory and New Institutional Economy are used to explain the genesis of the organization. It is concluded that cooperative organization should not be proposed as a solution for any type of activity. One should take into account the kind of activity and the organizational culture already established by the organization, this time in diamonds digging, which led to an inadequate appropriation, although involuntarily, of a cooperative organizational form.

description: Recently N. Arkani-Hamed and S. Dimopoulos proposed a supersymmetric model \cite{Arkani-Hamed:2004fb}, dubbed "Split Supersymmetry" in Ref. \cite{Giudice:2004tc}, which can remove most of the unpleasant shortcomings of TeV Supersymmetry. In this model all scalars except one finely tuned Higgs boson are ultra heavy while the neutralino and chargino might remain light in order to achieve gauge coupling unification and accord with the dark matter density. In this paper, we investigated the impact of this new model on chargino pair production at next generation linear colliders. Our numerical results show that this process can be used to probe sneutrino mass up to 10 TeV. Therefore, precise measurements of chargino pair production at the linear colliders could distinguish Split Supersymmetry from TeV Supersymmetry.

description: Connected and automated vehicles have been recently categorized as cybephysical entities, tightly related with a part of the Internet of Things (IoT) network. As a consequence the attack surface of a modern vehicle is increased, which added to the automation trend, makes cibersecurity risks a higher threat in the road. In this work a framework for automated vehicles is described, with the objective of validating security strategies when performing cooperative maneuvers. A review of the state of the art in automotive cibersecurity is presented, along its effect in automated vehicles, making special emphasis in inter-vehicle (V2V) communication and to the infrastructure (V2I). Moreover, two maneuvers are studied and a series of safety factors, taking into consideration the posible intervention of external malicious agents.

description: We investigate the time evolution of the six-component electron pressure tensor in a hybrid code studying consequences for the two-dimensional reconnection process in an initially perturbed Harris sheet. We put forward that two tensor components (a diagonal and a non-diagonal one) grow in an unstable way unless an isotropization operator is considered. This isotropization term is physically associated with an electron heat flux. As a consequence, we put forward that an enhanced value of a diagonal component is observed in the very middle of field reversal at sub-ion scale. Because of the increase of the kinetic pressure, the magnetic field is decreased in this electron layer, hence increasing the associated out-of-plane current at its edges and leading to its bifurcation. The bifurcation mechanism is based on the presence of electron pressure anisotropy, related to the gradient of inflow electron bulk velocity. The gradient in the inflow direction of the enhanced diagonal electron pressure tensor component results in the deceleration of the ions entering the X-point region. We suggest that bifurcated current sheets resulting from the anisotropies/agyrotropies of the six-component electron pressure tensor correspond to smaller reconnection rates comparing to non-bifurcated ones.

This generalization extends the Feynman-Dyson derivation and it admits discrete models. The methods of the present paper are diagrammatic. In this form, the theory is entirely a consequence of the choice of definition of space and time derivatives as commutators.

description: X-ray luminosity ($L_X$) originating from high-mass X-ray binaries (HMXBs) is tightly correlated with the host galaxy's star-formation rate (SFR). We explore this connection at sub-galactic scales spanning ${\sim}$7 dex in SFR and ${\sim}$8 dex in specific SFR (sSFR). There is good agreement with established relations down to ${\rm SFR {\simeq} 10^{-3}\,M_\odot \, yr^{-1}}$, below which an excess of X-ray luminosity emerges. This excess likely arises from low mass X-ray binaries. The intrinsic scatter of the $L_X$-SFR relation is constant, not correlated with SFR. Different star formation indicators scale with $L_X$ in different ways, and we attribute the differences to the effect of star formation history. The SFR derived from H$α$ shows the tightest correlation with X-ray luminosity because H$α$ emission probes stellar populations with ages similar to HMXB formation timescales, but the H$α$-based SFR is reliable only for $\rm sSFR{>}10^{-12}\,M_\odot \, yr^{-1}/M_\odot$.

Quality filtering and normalization for microarray-based CGH data
Creators: name: Khojasteh Lakelayeh, Mehrnoush
Publisher: name: University of British Columbia
Year: 2009

description: Altered copy numbers of DNA sequences are a characteristic of solid tumors. Microarray-based Comparative Genomic Hybridization (CGH) has emerged as a promising technology that has the potential to identify minute genomic changes, in the order of single DNA copy number changes, at the gene level. The data to be extracted from the two microarray images of a 2-color microarray experiment, in the image analysis step, are the ratios of the fluorescent intensities of each spot of the microarray in one image and that of the corresponding spot in the other image. Without identifying the sources of experimental error, and correcting for these errors or removing the data corrupted by significant errors, microarray results can lead to incorrect experimental conclusions. This research focuses on improving the "image analysis" step of array-CGH experiments. The aim is to reduce the variability and increase the validity of the experimental results. Two issues are addressed in this work: 1) identifying spots likely to be of poor quality, and 2) normalization of the data to remove systematic errors. In this work, we present a novel approach to quality filtering of microarray spots. We use a variety of shape and image texture measures and design a binary decision tree to discriminate between the spots likely to produce meaningful data and the ones with unreliable measurement data. The proposed procedure is shown to reduce the variability of the data resulting from the low quality spots. In addressing the second issue, possible sources of systematic variations are examined and accordingly a three-step normalization scheme is used to remove these systematic variations. The normalization scheme we used consists of the following steps. The spatial bias of the ratio of each spot is estimated using a sliding window centered on each spot and the median of the ratios of the spots inside the window is calculated. The spatial bias is then removed from the data. In the next step, microplate effects are removed from the data. In the final step, the intensity dependent bias is estimated by fitting a LOESS curve to the logarithm of ratios of spots as a function of the intensities of spots. This bias is then subtracted from the log ratios. This normalization scheme was shown to increase the accuracy and precision of microarray data.

As-grown high-quality films showed uniform surface topography and near ideal stoichiometry with a body-centered tetragonal crystal structure. Temperature-dependent longitudinal resistivity can be understood with dominant interband s-d electron-phonon scattering in the temperature range 5-40 K. Hall measurements confirmed the semimetallic nature of the films with electron dominated charge carrier density near 7.15*10^21 cm^-3 at 5 K.

Within the family tree of this process, we consider the smallest subtree containing the genealogy of the extant individuals together with the genealogy of the recorded extinct individuals. We introduce a novel representation of such subtrees in terms of a point-process, and provide asymptotic results on the distribution of this point-process as the number of extant individuals increases. We motivate the study within the scope of a coherent analysis for an a priori model for macroevolution.

description: The full use of resource capacities of agricultural enterprises favorably affects the general increase in economic efficiency and rational production making them more competitive in the market. This creates the need for constant improvement of business strategies that uses all available resources to create the most profitable production. The main objective of this study was to find the ideal structure of production in agricultural enterprise and to enable the realization of maximum profit using the available production resources (land, mechanization, labor forces). As the basic method of planning, this study used the simplex method of linear programming which gives the most profitable sowing structure after detailed analysis of resources and achieved results, based on the limitations and gross margin. This work showed that the use of modern methods in production planning is one of the cheapest and safest methods for development of agricultural enterprises.

description: Based on the results of our questionnaire survey, our study presents the major operational features of LEADER LAGs established in Hungary in the second half of 2007. Our national survey indicated that most of the partnerships established do not have experience in the implementation of community-based rural development programmes and there are no traditions and practices for development cooperation, which may cause problems as the success of programme implementation highly depends on the preparedness of local society, on the cooperation of local people. The survey indicates that the development of areas covered by LAGs is hindered by so-called soft factors characterizing human resources (rural people and communities). Therefore human resources are not only factors of the rural economy but areas for development as well. Having examined the tasks of LAGs, it can be established that they deem it to be their principal task to grant support funds. In our opinion, performance of this task is obviously necessary but far from sufficient to fulfil their catalyst role expected in local developments. For this purpose, it is essential for action groups to play a proactive role in organizing and thereby increase the capacity of local communities, a prerequisite for implementing a LEADER programme. In accordance with the basic principle of subsidiarity, rural development should be implemented locally, managed by local communities, and decisions should be made at local levels in a decentralized manner. At the same time, the survey points out that LAGs operate under strong government influence and control, leading to the conclusion that the Hungarian practice of the LEADER programme is characterized by decentralization without subsidiarity. In the present structure, the activities of LAGs are predominantly financed from central resources. Administration is the primary goal of their financing, which restricts their effective and efficient operations, thereby the successful implementation of the LEADER programme. It is unquestionable that LAGs need to be centrally financed since their operation is fundamental for programme implementation, but this requires more than acting in their present role of distributing resources. In order for action groups to fulfil their real roles to boost local developments, they need to recognize their mission; and from the financing and regulatory side, they must be enabled to complete the tasks expected from them and their function.

description: The quantum Hall superfluid is presently the only viable candidate for a realization of quasiparticles with fractional Berry phase statistics. For a simple vortex excitation, relevant for a subset of fractional Hall states considered by Laughlin, non-trivial Berry phase statistics were demonstrated many years ago by Arovas, Schrieffer, and Wilczek. The quasiparticles are in general more complicated, described accurately in terms of excited composite fermions. We use the method developed by Kjonsberg, Myrheim and Leinaas to compute the Berry phase for a single composite-fermion quasiparticle, and find that it agrees with the effective magnetic field concept for composite fermions. We then evaluate the "fractional statistics", related to the change in the Berry phase for a closed loop caused by the insertion of another composite-fermion quasiparticle in the interior. Our results support the general validity of fractional statistics in the quantum Hall superfluid, while also giving a quantitative account of corrections to it when the quasiparticle wave functions overlap. Many caveats, both practical and conceptual, are mentioned that will be relevant to an experimental measurement of the fractional statistics. A short report on some parts of this article has appeared previously.

We show that by including the helicity flipping amplitudes (with energy dependence given by the generalized counting rule) and their interference with the Landshoff amplitude, we are able to reproduce the energy dependence of all cross-section and spin-correlation (A$_{NN}$) data available above the resonance region. The pion-photoproduction data can also be described by this approach, but in this case data with much finer energy spacing is needed to confirm the oscillations about the scaling behavior.

description: The general objective of this paper is to present the world importance of dairy sector and to illustrate present tendency of milk production, consumption, trade and prices mainly based on FAO data base. World milk production was 711 million tonnes in 2010 and it is expected to increase in the future. The most significant milk producers are the EU(27), the United States and from the Asian countries, India and China. Developed countries give one-third of world milk production, while more than two-third of world dairy herd can be found in developing countries. Milk production growth is a future tendency mainly in China, India, Pakistan, Argentina and Brazil. The average level of consumption of milk and milk products is 103,6 kg/capita/year and it will increase in developing and developed countries as well. The ratio of international trade of milk and milk products to production is 6 percent and it may expand in the future. New Zealand, the EU(27), the United States and Australia are the major exporters. There is a strong demand for milk and milk products among others from the Asian countries, the Russian Federation, Algeria, Mexico, Saudi Arabia and the United States. Analysis of world market price of the most important dairy products it represents a strong recovery from last year, but it still remains 20 percent below its peak value in early 2008. However prices have doubled compared with prices of period of 2002–2004.

description: We present high-quality spectra of the majority of stars that have been classified as Oe and find that their published spectral types are generally too early, most likely due to infilling of HeI lines. As a matter of fact, all stars classified as Oe actually fall inside the range O9-B0 with the important exception of HD155806 (O7.5III) and perhaps HD39680 (difficult to classify, but likely O8.5V). Observations of a sample of objects with published spectral types in the O9-B0 range previously classified as peculiar or emission-line stars fail to reveal any new Oe star with spectral type earlier than O9.5. Most objects classified as peculiar in ``classical'' literature show signs of binarity in our spectra, but no spectral anomalies. We conclude that there is likely a real decline in the fraction of Be stars for spectral types earlier than B0, not due to observational bias. The few Oe stars with spectral types earlier than O9.5 deserve detailed investigation in order to provide constraints on the physical reasons of the Be phenomenon.

description: Emotional labour, as a self-contained field of research, is only three decades old. This study aims to summarize key findings from investigations of the last ten years in an attempt to provide a reference for interpretation of organizational emotions and the organizational aspects of emotional labour. It makes no secret of its aim being to call the attention of anybody dealing with people as workforce that work no longer has only physical or mental aspects, but an emotional dimension as well. Most often this latter dimension lives an independent life. Normally, it is not regulated, tracked, appreciated or rewarded properly, which might send a message to employees that it is not really important. However, emotional labour is a concomitant of most professions and jobs. Where it is not given any conscious consideration by either the employer nor its employees, numerous opportunities of making it easier or improving it may be lost.

description: The advent of topological phases of matter revealed a variety of observed boundary phenomena, such as chiral and helical modes found at the edges of two-dimensional (2D) topological insulators. Antichiral states in 2D semimetals, i.e., copropagating edge modes on opposite edges compensated by a counterpropagating bulk current, are also predicted, but, to date, no realization of such states in a solid-state system has been found. Here, we put forward a procedure to realize antichiral states in twisted van der Waals multilayers, by combining the electronic Dirac-cone spectra of each layer through the combination of the orbital moiré superstructure, an in-plane magnetic field, and inter-layer bias voltage. In particular, we demonstrate that a twisted van der Waals heterostructure consisting of graphene/two layers of hexagonal boron nitride [(hBN)$_2$]/graphene will show antichiral states at in-plane magnetic fields of 8 T, for a rotation angle of 0.2$^{\circ}$ between the graphene layers. Our findings engender a controllable procedure to engineer antichiral states in solid-state systems, as well as in quantum engineered metamaterials.

description: We discuss the derivation and the solutions of integro-differential equations (variable-order time-fractional diffusion equations) following as continuous limits for lattice continuous time random walk schemes with power-law waiting-time probability density functions, whose parameters are position-dependent. We concentrate on subdiffusive cases and discuss two situations as examples: A system consisting of two parts with different exponents of subdiffusion, and a system in which the subdiffusion exponent changes linearly from one end of the interval to another one. In both cases we compare the numerical solutions of generalized master equations describing the process on the lattice with the corresponding solutions of the continuous equations, which follow by exact solution of the corresponding equations in the Laplace domain with subsequent numerical inversion using the Gaver-Stehfest algorithm.

Towards Complete Neutrino Mixing Matrix and CP-Violation
Creators: name: Petcov, S. T.
Publisher: name: arXiv
Year: 2004
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)
subject: FOS: Physical sciences

description: The compelling experimental evidences for oscillations of solar, atmospheric and reactor neutrinos imply the existence of 3-neutrino mixing in vacuum. We review the phenomenology of 3-neutrino mixing, and the current data on the 3-neutrino mixing parameters. The opened questions and the main goals of future research in the field of neutrino mixing and oscillations are outlined. A phenomenological approach for understanding the pattern of neutrino mixing as an interplay between the mixing, arising from the charged lepton sector, and bimaximal mixing, arising from a neutrino Majorana mass matrix, is considered with emphasis on the CP-violating case. We comment also on planned future steps in the experimental studies of neutrino mixing.

Low-complexity iterative decoding for bit-interleaved coded modulation
Creators: name: Liu, Jeff Tai-Lin
Publisher: name: University of British Columbia
Year: 2009

description: In this thesis, bandwidth-efficient transmission with bit-interleaved coded modulation (BICM) over fading channels is considered. The main focus of this work is on the design and analysis of iterative decoding schemes employing hard-decision feedback. Although suboptimum by nature, hard-decision feedback allows for low-complexity iterative decoders, which renders this approach advantageous for practical implementations. Two particular 16-ary modulation schemes with their corresponding decoders are considered for bandwidth-efficient transmission. The first scheme is 16-ary quadrature amplitude modulation (16QAM) with coherent iterative decoding (ID), so-called BICM-ID, which relies on (possibly imperfect) channel estimation. We analyze the reliability of the output of the demodulator, which is the inner component decoder in the iterative decoding scheme, and we propose the application of a metric truncation technique to improve the quality of the decision variable and thus the performance of hard-decision feedback iterative decoding. Simulation results for different variants of this metric truncation show notable gains in power efficiency, while decoding complexity is not increased. The second scheme we consider is so-called twisted absolute amplitude and differential phase-shift keying (TADPSK), which allows for iterative decoding without the need for channel estimation. We extend previous work on iterative decision-feedback decoding for TADPSK, so-called iterative decision-feedback differential demodulation (DFDM), and propose a sliding-window DFDM (SWDFDM) module as inner component decoder. Similar to the case of 16QAM, the application of metric truncation yields significant performance improvements also for TADPSK transmission. Finally, we compare 16QAM and TADPSK transmission by means of simulations. Depending on the quality of channel estimation, TADPSK with low-complexity iterative DFDM is shown to outperform 16QAM BICM-ID in some cases.

description: Over the past decade the global agri-food industry has come under increasing attack by advocacy groups related to their production and marketing processes (Bowmar and Gow, 2009). Advocacy groups have used these attacks to exploit the growing intergenerational disconnect between consumers and farming to campaign for narrowly defined political ideals while challenging traditional agricultural practices (Olin, 1999). This disconnect has provided advocacy groups the opportunity to use boycotts and other media attacks to severely adverse impact not only branded manufacturers and retailers, but their farmer suppliers. The agri-food industry’s challenge is to understand how to develop appropriate individual and collective responses to these attacks that minimize their current and future adverse impact and provide mutually beneficial outcomes for all of the channel members. Using an instrumental case study of the international cocoa and chocolate industry’s response to the child labour abuse and trafficking claims, we analyse and evaluate the alternative individual and collective responses that firms can implement to minimize their current and future adverse impact from advocacy attacks and provide mutually beneficial outcomes for all of the channel members. This paper follows a comparative institutional analysis methodology to analyse the multiple nested case studies and evaluate the impact and implications of each alternative.

description: Developing agents that can perform challenging complex tasks is the goal of reinforcement learning. The model-free reinforcement learning has been considered as a feasible solution. However, the state of the art research has been to develop increasingly complicated techniques. This increasing complexity makes the reconstruction difficult. Furthermore, the problem of reward dependency is still exists. As a result, research on imitation learning, which learns policy from a demonstration of experts, has begun to attract attention. Imitation learning directly learns policy based on data on the behavior of the experts without the explicit reward signal provided by the environment. However, imitation learning tries to optimize policies based on deep reinforcement learning such as trust region policy optimization. As a result, deep reinforcement learning based imitation learning also poses a crisis of reproducibility. The issue of complex model-free model has received considerable critical attention. A derivative-free optimization based reinforcement learning and the simplification on policies obtain competitive performance on the dynamic complex tasks. The simplified policies and derivative free methods make algorithm be simple. The reconfiguration of research demo becomes easy. In this paper, we propose an imitation learning method that takes advantage of the derivative-free optimization with simple linear policies. The proposed method performs simple random search in the parameter space of policies and shows computational efficiency. Experiments in this paper show that the proposed model, without a direct reward signal from the environment, obtains competitive performance on the MuJoCo locomotion tasks.
