description: Current-driven magnetization switching in low-resistance Co40Fe40B20/MgO/Co40Fe40B20 magnetic tunnel junctions (MTJs) is reported. The critical-current densities Jc required for current-driven switching in samples annealed at 270C and 300C are found to be as low as 7.8 x 10^5 A/cm^2 and 8.8 x 10^5 A/cm^2 with accompanying tunnel magnetoresistance (TMR) ratios of 49% and 73 %, respectively. Further annealing of the samples at 350C increases TMR ratio to 160 %, while accompanying Jc increases to 2.5 x 10^6 A/cm^2. We attribute the low Jc to the high spin-polarization of tunnel current and small MsV product of the CoFeB single free layer, where Ms is the saturation magnetization and V the volume of the free layer.

description: Which organization model is appropriate for a cooperative enterprise depends on the prerequisites in its business environment. When conditions are changing, the firm must adapt itself. The entry of Sweden, Finland, and Austria into the European Union led to radical changes for agricultural cooperation, especially for Swedish cooperatives since agricultural policy was not allowed a transitional period. After two years, Swedish cooperatives have still not adapted their organization model despite poor agricultural profitability. The hindering factors are conservatism among members and difficult institutional conditions with regard to legislation and public opinion.
CD44-dependent hyaluronan-binding and T-lymphocyte migration
Creators: name: Mohseni Koochesfahani, Kasra
Publisher: name: University of British Columbia
Year: 2009

description: CD44 has been suggested to play a role in adhesive interactions mediating migration and extravasation of T cells into the tissues. This mediation is believed to occur as a result of CD44 binding to hyaluronic acid (HA) on the surface of endothelium. Among factors suggested to regulate this binding is the pro-inflammatory cytokine TNFα, which has been suggested to upregulate HA-binding through sulfation of the CD44 molecule. One of the objectives of this research proposal was aimed at determining the role of T cell activation, TNFα and TNFα receptors in HA binding by T lymphocytes. It was found that only highly activated T cells, which are the largest in cell size and expressed the highest levels of CD44 were the most efficient HA binders. TNFα exerts its effect on HA binding by regulating T cell activation. It increases HA binding under conditions where the cells were not optimally activated. The effects of TNFR1 (p55) and TNFR2 (p75) on HA binding can also be explained by their role in T cell activation. Thus, p55, which is not required for optimal T cell activation, has no effect on HA binding by anti-CD3 activated CD8 T cells. By contrast, p75[sub +/-] CD8 T cells, which were less optimally activated by anti-CD3 stimulation, bind much less HA than similarly activated wild type cells. The role of CD44 in migration of T lymphocytes in vivo was also determined. Various in vivo assays were used to determine whether CD44 was required for migration of polarized TH1 and TH2 cells into sites of inflammation and whether this migration correlated with HA binding. The role of CD44 in the migration of antigen-specific CD8 T cells at various times after antigen activation into lymphoid and non-lymphoid tissues was also determined. All these assays failed to demonstrate an essential role for CD44 in T cell migration. Thus, alternative mechanisms other than those mediated by CD44 are likely responsible for regulating T cell migration in vivo.

description: A comparative institutional economics approach is used to investigate the question of whether the governance structure of cooperatives is flawed in ways that would make it an inefficient or ineffective organization form for the political-social-economic environment at this turn to the new century. Cooperatives in four settings around the globe were studied intensively. The findings suggest that, while greater use of federated cooperatives and co-op-IOF hybrid models is required, the cooperative may be an ideal economic organization form to deal with the complexities of a global society in the century ahead.

description: Recent empirical work suggests that cooperative presence in differentiated product markets lowers the consumer prices of all brands. This paper focuses on the theoretical basis for this competitive yardstick effect by cooperatives. It identifies two market structures where the competitive yardstick theorem for cooperatives can be extended from farmer-first handler markets to differentiated consumer product markets. They are (1) oligopoly with significant barriers to entry and (2) monopolistic competition with entry but only non-price competition. In the latter, the cooperative can also ensure that the socially optimal number of brands (product variety) is provided by the industry. The theory also provides useful guidance for determining when supply-limiting conduct in differentiated product markets should be challenged as undue price enhancement under the Capper-Volstead law.

description: State cooperative councils serve a valuable role for local cooperatives by providing services including education, legislative monitoring and lobbying, and promotion of the cooperative form of business. This paper outlines the specific challenges that state councils are experiencing in today's changing agribusiness environment. The results of a survey of members of the Colorado Cooperative Council are reported. Logit analysis is performed to identify the factors contributing to the cooperatives' satisfaction with the state council and the cooperatives' use of the council's services. The paper concludes with suggestions for action by state councils.

description: Recent studies have revealed the complex structure of nerve signals in axons. Besides the electrical signal, mechanical and thermal effects are also detected in many experimental studies. In this paper, the mathematical models of heat generation are analysed within the framework of a general model derived earlier by the authors. The main mechanisms of the heat generation are seemingly the Joule heating and endo- and exothermic reactions. The concept of internal variables permits to model the heat relaxation typical to these reactions. The general energy balance of the whole signal is analysed based on physical mechanisms responsible for emerging the components of a signal. Some open questions are listed for further studies.

description: This paper analyzes how the proportion of patronage refunds a cooperative pays in cash affects the cash flow of individual patrons and how an individual patron's preferences regarding patronage refunds and equity revolvement are affected by age and other factors. Using an estimated patron age distribution and a collective choice model based on the preferences of the median voter, we predict which patronage refund and equity revolvement practices should dominate under selected patron and cooperative characteristics. We also examine the role of former patrons in determining refund and revolvement practices and how outcomes may be affected by alternative voting schemes.

description: This paper employs household survey data to further examine whether biotech food labeling has an impact on consumers’ vegetable oil purchasing decision. Direct variables indicating consumers’ response to label regulation are employed to test label effect. Endogeneity issues impeding label effect measurement are especially addressed. The empirical results support our previous finding that in the short run the market share of biotech oil decreased significantly by a small amount as a result of label enforcement. To capture a comprehensive picture of the role played by biotech food label and the market trend in the long run, major concerns and needs for the future are raised including a series of data issues and a special focus on who make purchasing decision.

description: We study the role of noise on the nature of the transition to collective motion in dry active matter. Starting from field theories that predict a continuous transition at the deterministic level, we show that fluctuations induce a density-dependent shift of the onset of order, which in turns changes the nature of the transition into a phase-separation scenario. Our results apply to a range of systems, including the topological models in which particles interact with a fixed number of nearest neighbors, which were believed so far to exhibit a continuous onset of order. Our analytical predictions are confirmed by numerical simulations of fluctuating hydrodynamics and microscopic models.

description: Self-assembled Au atomic wires on stepped Si surfaces are metallic, as evidenced by one-dimensionally dispersing plasmonic excitation. Here, we investigate the effects of oxidation on metallicity along such Au atomic wires on a regularly stepped Si(553) surface by employing infrared absorption and high-resolution electron energy loss spectroscopies. Our results indicate that only the Si environment undergoes oxidation, which has a remarkably small effect on the plasmon dispersion. However, close to k∥ → 0 the plasmon dispersion starts at increasingly higher energies as a function of oxygen exposure, which is attributed to standing wave formation on small sections of Au wires generated by the introduction of O atoms as scattering centers, not to electronic gap opening. This interpretation is in full agreement with the findings by infrared spectroscopy and low-energy electron diffraction.

description: We show that twisting of an infinite straight three-dimensional tube with non-circular cross-section gives rise to a Hardy-type inequality for the associated Dirichlet Laplacian. As an application we prove certain stability of the spectrum of the Dirichlet Laplacian in locally and mildly bent tubes. Namely, it is known that any local bending, no matter how small, generates eigenvalues below the essential spectrum of the Laplacian in the tubes with arbitrary cross-sections rotated along a reference curve in an appropriate way. In the present paper we show that for any other rotation some critical strength of the bending is needed in order to induce a non-empty discrete spectrum.

description: We report on the discovery of a large-scale wall in the direction of Abell 22. Using photometric and spectroscopic data from the Las Campanas Observatory and Anglo-Australian Telescope Rich Cluster Survey, Abell 22 is found to exhibit a highly unusual and striking redshift distribution. We show that Abell 22 exhibits a foreground wall-like structure by examining the galaxy distributions in both redshift space and on the colour-magnitude plane. A search for other galaxies and clusters in the nearby region using the 2dF Galaxy Redshift Survey database suggests that the wall-like structure is a significant large-scale, non-virialized filament which runs between two other Abell clusters either side of Abell 22. The filament stretches over at least >40 Mpc in length and 10 Mpc in width at the redshift of Abell 22.

description: What is the impact of democratic control on cooperative decision making? The purpose of this article is to present a conceptual framework for the analysis of democratic control. It suggests that democratic control does not guarantee optimal decisions for the cooperative. Suboptimal decisions result from simple majority rule, the activity of cooperative interest groups, members pursuing their interests to the detriment of the cooperative firm, and management pursuing its interests at the expense of the membership. This paper also outlines strategies cooperatives can adopt to correct the problems due to democratic control.

This includes equivariant BV formalism. In particular, an analogue of intertwiner between Weil and Cartan models allows to clarify the general relation between integrated and unintegrated vertex operators in string worldsheet theory.

Reverse Engineering the Behaviour of Twitter Bots

description: Online social media platforms such as Twitter offer flexible and effective means of communication on a large scale. The use of Twitter by political figures and government officials increases the wider acceptance of the medium. However, the use of automated accounts known as bots for election campaigns raises concerns that the medium is now being used to disseminate political propaganda aimed at manipulating public opinion. Recent research has shown significant success in the detection of bots. While there are approaches to distinguish automated from regular user accounts, information about their masters, targets, strategies, biases and antagonisms remains harder to obtain. This is a challenging task but can lead to a better understanding of their use in political campaigns. In this thesis, we proposed an approach to reverse engineering the behaviour of Twitter bots to create a visual model explaining their actions. We use machine learning to infer a set of understandable rules governing the behaviour of a bot and a visual notation to make such rules accessible to a non-technical audience. We propose the notion of differential sentiment to provide means of understanding their behaviour with respect to the topics on their network in relation to both their sources of information (friends) and their target audience (followers). Respectively, this provides insights into their bias and antagonism with the target audience. We evaluated our approach using prototype bots we created and selected real Twitter bots. The results show that the approach is successful in describing the behaviour of the bots correctly and that the approach can help to understand their role and impact.This thesis contributes to knowledge with regard to understanding the behaviour and strategies of Twitter bots. As shown by two case studies, the approach can help to monitor the use of bots to manipulate public opinion and to create transparency in public debate.

description: In this paper, we investigate the residual deformation field in the vicinity of nano-scratch tests using two orientations of a Berkovich tip on an (001) Cu single crystal. We compare the deformation with that from indentation, in an attempt to understand the mechanisms of deformation in tangential sliding. The lattice rotation fields are mapped experimentally using high-resolution electron backscatter diffraction (HR-EBSD) on cross-sections prepared using focused ion beam (FIB). A physically-based crystal plasticity finite element model (CPFEM) is used to simulate the lattice rotation fields, and provide insight into the 3D rotation field surrounding nano-scratch experiments, as it transitions from an initial static indentation to a steady-state scratch. The CPFEM simulations capture the experimental rotation fields with good fidelity, and show how the rotations about the scratch direction are reversed as the indenter moves away from the initial indentation.

description: We have collected and analyzed data taken in different spectral bands (from X-ray to optical and infrared) of the field of GRB031220 and we present results of such multiband observations. Comparison between images taken at different epochs in the same filters did not reveal any strong variable source in the field of this burst. X-ray analysis shows that only two of the seven Chandra sources have a significant flux decrease and seem to be the most likely afterglow candidates. Both sources do not show the typical values of the R-K colour but they appear to be redder. However, only one source has an X-ray decay index (1.3 +/- 0.1) that is typical for observed afterglows. We assume that this source is the best afterglow candidate and we estimate a redshift of 1.90 +/- 0.30. Photometric analysis and redshift estimation for this object suggest that this GRB can be classified as a Dark Burst and that the obscuration is the result of dust extinction in the circum burst medium or inside the host galaxy.

description: This paper examines the potential benefits of introducing a new payment scheme in a sugarcane processing cooperative. Findings suggest that a use-value payment system would increase individual and total members’ net returns significantly over a sugar-based system. The proposed payment system would change the incentive structure so varieties with higher processing quality would become more appealing. In addition, the cooperative plant would be used more uniformly throughout the processing season and payments to members would be more consistent with their contribution to cooperative surplus.

description: Hot spot of Berry curvature is usually found at Bloch band anti-crossings, where the Hall effect due to the Berry phase can be most pronounced. With small gaps there, the adiabatic limit for the existing formulations of Hall current can be exceeded in a moderate electric field. Here we present a theory of non-adiabatic Hall effect, capturing non-perturbatively the across gap electron-hole excitations by the electric field. We find a general connection between the field induced electron-hole coherence and intrinsic Hall velocity. In coherent evolution, the electron-hole coherence can manifest as a sizeable ac Hall velocity. When environmental noise is taken into account, its joint action with the electric field favors a form of electron-hole coherence that is function of wavevector and field only, leading to a dc nonlinear Hall effect. The Hall current has all odd order terms in field, and still retains the intrinsic role of the Berry curvature. The quantitative demonstration uses the example of gapped Dirac cones, and our theory can be used to describe the bulk pseudospin Hall current in insulators with gapped edge such as graphene and 2D MnBi$_{2}$Te$_{4}$

description: We study how the proportion of star-forming galaxies evolves between z=0.8 and z=0 as a function of galaxy environment, using the [OII] line in emission as a signature of ongoing star formation. Our high-z dataset comprises 16 clusters, 10 groups and another 250 galaxies in poorer groups and the field at z=0.4-0.8 from the ESO Distant Cluster Survey, plus another 9 massive clusters at similar redshifts. As a local comparison, we use samples of galaxy systems selected from the Sloan Digital Sky Survey at 0.04< z < 0.08. At high-z most systems follow a broad anticorrelation between the fraction of star-forming galaxies and the system velocity dispersion. At face value, this suggests that at z=0.4-0.8 the mass of the system largely determines the proportion of galaxies with ongoing star formation. At these redshifts the strength of star formation (as measured by the [OII] equivalent width) in star-forming galaxies is also found to vary systematically with environment. Sloan clusters have much lower fractions of star-forming galaxies than clusters at z=0.4-0.8 and, in contrast with the distant clusters, show a plateau for velocity dispersions $ \ge 550 km s^-1$, where the fraction of galaxies with [OII] emission does not vary systematically with velocity dispersion. We quantify the evolution of the proportion of star-forming galaxies as a function of the system velocity dispersion and find it is strongest in intermediate-mass systems (sigma ~ 500-600 km s^-1 at z=0). To understand the origin of the observed trends, we use the Press-Schechter formalism and the Millennium Simulation and show that galaxy star formation histories may be closely related to the growth history of clusters and groups. We propose a scheme that is able to account for the observed relations between the star-forming fraction and σ[abridged].

description: We investigate the possible progenitors of the planetary nebulae (PNs) which populate the top 0.5 mag of the [O III] 5007 planetary nebula luminosity function (PNLF). We show that the absolute luminosity of the PNLF cutoff demands that the central stars of these most luminous planetaries be greater than 0.6 Msun, and that such high-mass PN cores must exist in every galaxy. We also use the bolometric-luminosity specific PN number density to show that in early-type galaxies, [O III]-bright planetaries are relatively rare, with only about 10% of stars evolving to these bright magnitudes. We demonstrate that the combination of these two facts implies that either all early-type systems contain a small, smoothly distributed component of young (< 1 Gyr old) stars, or another mechanism exists for creating high-core mass planetaries. We argue that binary-star evolution is this second mechanism, and demonstrate that blue stragglers have the appropriate core properties and number density to explain the observations. We discuss the implications of this alternative mode of stellar evolution, and speculate on how coalesced binaries might affect the use of PNs for measuring a galaxy's star-formation history and chemical evolution.

The EU TRQs are described and their origin is explained. Descriptive statistics are provided in order to assess the implementation of the market access provisions of the 1994 UR Agreement. Transparency of the EU TRQ system and fill rates of TRQs are examined. Overall, the EU's record in the area of TRQs is relatively satisfactory, compared with those of other countries. Concerns remain, however, as to the exact articulation of the (regional) Europe Agreement and some quotas under minimum access.

description: The turbulent Prandtl number has been calculated in the two-loop approximation of the $\eps$ expansion of the stochastic theory of turbulence. The strikingly small value obtained for the two-loop correction explains the good agreement of the earlier one-loop result with the experiment. This situation is drastically different from other available nontrivial two-loop results, which exhibit corrections of the magnitude of the one-loop term. The reason is traced to the mutual cancellation of additional divergences appearing in two dimensions which have had a major effect on the results of previous calculations of other quantities.

description: Endometrial cancer (EC) is the commonest gynaecologic malignancy in developed countries and its incidence is rising. Although excellent prognosis is associated with early stage disease, treatment for late stage cases is challenging and the treatment options limited.Racial differences have been shown in Black and Caucasian women diagnosed with EC however, evidence for other racial groups is limited with Asian patients being particularly under-represented in the literature.The aims of the study were to propose effective targeted drug treatments suitable for subsequent testing in animal models of EC and to identify differences in the mutational profile of endometrial tumours between British White (BW) and South Asian (BSA) women.CUDC-907, a PI3K and HDAC inhibitor, was the most effective monotherapy treatment in EC cells. Several combination treatments showed synergism and efficacy in EC cell lines with the most efficacious being CUDC-907 and S63845 (MCL1 inhibitor) combined with the MEK inhibitor PD0325901.Although there was no significant difference in the overall mutation frequency of the 10 genes analyzed, numerous differences were observed between the two racial groups. PIK3CA and PTEN mutations were positively associated in the BSA but not in the BW group. On the contrary, BW women had co-existent ARID1A and PI3K pathway mutations, which was not shown in BSA women. BSA women had higher grade disease in our cohort and survival data are eagerly anticipated.A range of targeted inhibitory drugs emerged from this study showing in vitro efficacy, alone or in combination, in endometrial cancer cells. Further validation of these therapeutic options in animal models is needed prior to confirming their suitability for use in EC. This study, the first to attempt a comparison between a Caucasian and South Asian cohort of women in genes frequently driving carcinogenesis in EC, showed several differences with translational and clinical relevance.

description: We compute families of spherically symmetric neutron-star models in two-derivative scalar-tensor theories of gravity with a massive scalar field. The numerical approach we present allows us to compute the resulting spacetimes out to infinite radius using a relaxation algorithm on a compactified grid. We discuss the structure of the weakly and strongly scalarized branches of neutron-star models thus obtained and their dependence on the linear and quadratic coupling parameters $α_0$, $β_0$ between the scalar and tensor sectors of the theory, as well as the scalar mass $μ$. For highly negative values of $β_0$, we encounter configurations resembling a "gravitational atom", consisting of a highly compact baryon star surrounded by a scalar cloud. A stability analysis based on binding-energ calculations suggests that these configurations are unstable and we expect them to migrate to models with radially decreasing baryon density {\it and} scalar field strength.

description: Na emergência da discussão sobre a pobreza enquanto um mecanismo de exclusão social, mediada pelas relações interpessoais e institucionais, emerge a categoria dos afetos, da qual pouco se evoca na análise da exclusão, como aponta Sawaia (2008) em sua análise sobre o sofrimento ético-político como categoria de exclusão. Nesse cenário em que urge a necessidade de consideração do humano na totalidade de sua subjetividade, pontuando seus desejos, afetos e emoções, e no combate à pobreza do país a partir de implementação de políticas públicas, enquadra-se como interesse de pesquisa e de intervenção a reflexão sobre o movimento intersubjetivo realizado pelos sujeitos em situação de exclusão pela pobreza acerca da elaboração psicossocial de seu projeto de vida e dos sentidos do trabalho (Vigotski, 2000, 2004).

description: Preserving Culture Through PintaRebirth: How Public Institutions Can Better Serve Minority Teens examines a mural painting program at the Mexican American Cultural Center involving ten local Austin Hispanic teens. The researcher sought to better understand PintaRebirth’s goal of helping teens learn about personal and communal history through collaboration between researcher, public institution, professional mural artist, and local businesses and how other public institutions might reach that goal. Museums and historical/cultural centers have the ability to provide engaging and pertinent educational programming to minority teens. The PintaRebirth program and this subsequent research give some indications of how institutions might accomplish that goal. Stories the students in the program told provide readers an uncommon look into making a connection with this population. Findings show how that connection was made and give note to why it is important

description: The d+d->alpha+eta reaction has been investigated near threshold using the ANKE facility at COSY-Juelich. Both total and differential cross sections have been measured at two excess energies, Q=2.6 MeV and 7.7 MeV, with a subthreshold measurement being undertaken at Q=-2.6 MeV to study the physical background. While consistent with isotropy at the lower energy, the angular distribution reveals a pronounced anisotropy at the higher one, indicating the presence of higher partial waves. Options for the decomposition into partial amplitudes and their consequences for determination of the s-wave eta-alpha scattering length are discussed.

description: U.S. peanut, sugar, and tobacco tariff rate quotas (TRQs) are allocated to suppliers on an historical market share basis. Once allocated they become difficult to redistribute to accommodate changes in comparative advantage among suppliers. The distribution of trade departs increasingly from the tariff-equivalent distribution advocated by the WTO principle of nondiscrimination. Article XIII of the GATT regarding the rules for historical allocation is examined and applied to four cases of historical allocation: domestic tobacco quota and TRQs for peanuts, sugar and tobacco. The difference between the law enforcement objective of the WTO and the Pareto optimization objective assumed by economists is stressed throughout.

description: Supersymmetric models with Dirac instead of Majorana gaugino masses have distinct phenomenological consequences. In this paper, we investigate the electroweakino sector of the Minimal Dirac Gaugino Supersymmetric Standard Model (MDGSSM) with regards to dark matter (DM) and collider constraints. We delineate the parameter space where the lightest neutralino of the MDGSSM is a viable DM candidate, that makes for at least part of the observed relic abundance while evading constraints from DM direct detection, LEP and lowenergy data, and LHC Higgs measurements. The collider phenomenology of the thus emerging scenarios is characterised by the richer electroweakino spectrum as compared to the Minimal Supersymmetric Standard Model (MSSM) -- 6 neutralinos and 3 charginos instead of 4 and 2 in the MSSM, naturally small mass splittings, and the frequent presence of long-lived particles, both charginos and/or neutralinos. Reinterpreting ATLAS and CMS analyses with the help of SModelS and MadAnalysis 5, we discuss the sensitivity of existing LHC searches for new physics to these scenarios and show which cases can be constrained and which escape detection. Finally, we propose a set of benchmark points which can be useful for further studies, designing dedicated experimental analyses and/or investigating the potential of future experiments.

description: We analyse the optical (or microwave) tunnelling properties of electromagnetic waves passing through thin films presenting a specific index profile providing a cut-off frequency, when they are used below this frequency. We show that contrary to the usual case of a square index profile, where tunnelling is accompanied with a strong attenuation of the wave due to reflection, such films present the possibility of a reflectionless tunnelling, where the incoming intensity is totally transmitted.

description: Using a survey of over 320 consumers from across the state of Indiana, we estimate an ordered probit model to determine the demographic and attitudinal factors which are most important in predicting the likelihood of consumers to purchase products that are produced within the state. Our results indicate that the willingness to purchase locally produced agricultural products increases with time of residency in the state, and we find a greater tendency for female consumers to purchase such products. We also find that quality perceptions play a critical role in these food purchase-decisions. We underscore the importance of maintaining minimum quality standards to maximize the effectiveness of state level agricultural promotion programs.
