description: As a novel type of fermionic state, hybrid nodal loop with the coexistence of both type-I and type- II band crossings has attracted intense research interest. However, it remains a challenge to realize hybrid nodal loop in both two-dimensional (2D) materials and in ferromagnetic (FM) materials. Here, we propose the first FM hybrid nodal loop in 2D CrN monolayer. We show that the material has a high Curie temperature (> 600 K) FM ground state, with the out-of-plane [001] magnetization. It shows a half-metallic band structure with two bands in the spin-up channel crossing each other near the Fermi level. These bands produce both type-I and type-II band crossings, which form a fully spin-polarized hybrid nodal loop. We find the nodal loop is protected by the mirror symmetry and robust against spin-orbit coupling (SOC). An effective Hamiltonian characterizing the hybrid nodal loop is established. We further find the configuration of nodal loop can be shifted under external perturbations such as strain. Most remarkably, we demonstrate that both type-I and type-II Weyl nodes can be realized from such FM hybrid nodal loop by simply shifting the magnetization from out-of-plane to in-plane. Our work provides an excellent candidate to realize FM hybrid nodal loop and Weyl fermions in 2D material, and is also promising for related topological applications with their intriguing properties.

description: Suppose $w$ is a sense-preserving harmonic mapping of the unit disk $\mathbb{D}$ such that $w(\mathbb{D})\subseteq\mathbb{D}$ and $w$ has a zero of order $p\geq1$ at $z=0$. In this paper, we first improve the Schwarz lemma for $w$, and then, we establish its boundary Schwarz lemma. Moreover, by using the automorphism of $\mathbb{D}$, we further generalize this result.

description: An all-order summation of core polarization diagrams using the low-momentum nucleon-nucleon interaction, V_low-k is presented. The summation is based on the Kirson-Babu-Brown (KBB) induced interaction approach in which the vertex functions are obtained self consistently by solving a set of non-linear coupled equations. It is found that the solution of these equations is simplified by using V_low-k, which is energy independent, and by employing Green functions in the particle-particle and particle-hole channels. We have applied this approach to the sd-shell effective interactions and find that the results calculated to all orders using the KBB summation technique are remarkably similar to those of second-order perturbation theory, average differences being less than 10%.

description: This paper presents a methodology to evaluate the impact of different policy scenarios using a farmer's utility function. The analysis shows the impact on farmers and on the environment. The case study is a community of irrigated farms (Bajo Carrión) in Northwestern Spain. The results obtained show how Agenda 2000 has little impact on farm crop distribution, gross margins, employment and environment (use of fertilizers and water). The most radical scenario (a 15 per cent COP price cut and no area payments) produces a 37.3 per cent reduction in farm gross margin, and an increase in fertilizer use of 6 per cent.
Homeward bound : a journey to cyberspace and back again in middle school French

description: Computer technology represents a new landscape for French teachers in British Columbia that is full of promise but barely explored. The purpose of writing this inquiry was to improve my teaching practice by examining my personal and professional life and to document how the decision to use technology influences pedagogy and impacts teaching and learning. Writing this narrative inquiry helped me understand the influence of my personal life history and the school culture on the teacher I have become, as well as how the development of personal practical knowledge led to my decision to learn to use technology to teach middle school French. By sharing my story I hope to offer insight into the possibilities that may be helpful to teachers interested in implementing technology in their French classes, and to administrators who are interested in finding ways to support teachers who are interested in implementing technology in their classrooms. The narrative inquiry formed the framework for the thesis as questions concerning the writing process, the development of self, and the significance of the selected stories were considered in reference to my experiences in the computer lab. Stories were selected from my childhood, from my experiences of parenting and teaching in northern British Columbia, and from my experiences learning to teach French in the regular classroom and in the computer lab. The process of selecting the stories and researching the literature regarding the development of teacher knowledge concerning using technology in second language instruction took place over a span of three years. Field texts consisting of journal entries, story fragments, student surveys, email messages and poetry, samples of student work and personal reflective writing were rewritten as the inquiry progressed into the final research text The author concluded by recognising that although technology offers tremendous possibilities for second language teachers there are significant constraints to successful implementation which are inherent in our current education system and teachers' personal beliefs about teaching and learning. Further, the role of examining beliefs about teaching and learning is tantamount to improving a practice. Conducting a narrative inquiry is one way to further understanding, which is the key to improving education.

description: Nodal-chain fermions, as novel topological states of matter, have been hotly discussed in non-magnetic materials. Here, by using first-principles calculations and symmetry analysis, we propose the realization of fully spin-polarized nodal chain in the half-metal state of LiV$_2$O$_4$ compound. The material naturally shows a ferromagnetic ground state, and takes on a half-metal band structure with only the bands from the spin-up channel present near the Fermi level. The spin-up bands cross with each other, which form two types of nodal loops. These nodal loops arise from band inversion and are under the protection of the glide mirror symmetries. Remarkably, we find the nodal loops conjunct with each other and form chain-like nodal structure. Correspondingly, the w-shaped surface states are also fully spin-polarized. The fully spin-polarized nodal chain identified here has not been proposed in realistic materials before. An effective model is constructed to describe the nature of nodal chain. The effects of the electron correlation, the lattice strains, and the spin-orbit coupling are discussed. The fully spin-polarized bulk nodal-chain and the associated nontrivial surface states for a half-metal may open novel applications in spintronics.

description: We have investigated the dielectric and magnetic properties of Eu$_{0.595}$Y$_{0.405}$MnO$_{3}$ $without$ the presence of the 4$f$ magnetic moments of the rare earth ions, and have found two ferroelectric phases with polarization along the $a$ and $c$ axes in a zero magnetic field. A magnetic field induced switching from one to the other ferroelectric phase took plase in which the direction of ferroelectric polarization changed from the a axis to the c axis by the application of magnetic fields parallel to the a axis. In contrast to the case of TbMnO$_{3}$, in which the 4$f$ moments of Tb$^{3+}$ ions play an important role in such a ferroelectric phase switching, the magnetic-field-induced switching between ferroelectric phases in Eu$_{0.595}$Y$_{0.405}$MnO$_{3}$ does not originate from the magnetic transition of the rare-earth 4$f$ moments, but from that of the Mn 3$d$ spins.

description: Adult Equivalent Scales (AES) in household consumption analysis are profoundly more appropriate and more revealing than the "average per capita" consumption, which treats every household member on an equal basis. This paper provides estimates of AES parameters for five important food groups of the typical Greek diet (meat, fish, fruits and vegetables, dairy products and legumes). Data from the 1993/94 Household Budget Survey were used and a Tobit limited dependent variable model was employed for estimation purposes. The results of the empirical analysis indicate that the age and gender composition of Greek households is a major determinant of food demand and consumption. In addition, the true household size varies substantially among the examined food groups and differs significantly from the "number of persons" measure of household size.

description: The model developed in this paper is applied to cotton seed and maize industries and examines the welfare implications of the Common Agricultural Policy (CAP) cotton and maize policy regimes in Greece, after its accession in the European Union (1981). The results of the quantitative analysis indicate that in both markets remarkable amounts have been transferred in favor of producers. Cotton farmers received, however, considerably higher amounts and their income protection levels rose faster than was the case for maize farmers. On the other hand, maize consumers have lost, in terms of economic welfare, during the whole period under consideration and particularly after the mid-80's. This was not the case for cotton seed consumers, since they were buying during the whole period at world market prices. Finally, and in terms of economic efficiency, it has been shown that the CAP cotton regime is by far the more efficient compared to the maize regime due to the kind of practiced policies and the differences in the elasticities of supply.

description: Here, we systematically investigate the structure, phase stability, half-metallicity, and topological electronic structure for a new topological spintronic material NaV2O4. The material has a tetragonal structure with excellent dynamical and thermal stabilities. It shows a half-metallic ground state, where only the spin-up bands present near the Fermi level. These bands form a Weyl nodal line close to the Fermi level, locating in the kz = 0 plane. The nodal line is robust against SOC, under the protection of the mirror symmetry. The nodal line band structure is very clean, thus the drumhead surface states can be clearly identified. Remarkably, the nodal line and drumhead surface states have the 100% spin polarization, which are highly desirable for spintronics applications. In addition, by shifting the magnetic field in-plane, we find that the Weyl nodal line can transform into single pair of Weyl nodes. The Weyl-line and Weyl-node fermions in the bulk, as well as the drumhead fermions on the surface are all fully spin-polarized, which may generate new physical properties and promising applications.

description: We present the phase diagram, in both the microcanonical and the canonical ensemble, of the Self-Gravitating-Ring (SGR) model, which describes the motion of equal point masses constrained on a ring and subject to 3D gravitational attraction. If the interaction is regularized at short distances by the introduction of a softening parameter, a global entropy maximum always exists, and thermodynamics is well defined in the mean-field limit. However, ensembles are not equivalent and a phase of negative specific heat in the microcanonical ensemble appears in a wide intermediate energy region, if the softening parameter is small enough. The phase transition changes from second to first order at a tricritical point, whose location is not the same in the two ensembles. All these features make of the SGR model the best prototype of a self-gravitating system in one dimension. In order to obtain the stable stationary mass distribution, we apply a new iterative method, inspired by a previous one used in 2D turbulence, which ensures entropy increase and, hence, convergence towards an equilibrium state.

description: The aim of this work is to contribute to the definition of an analytical approach for evaluating the dynamics in progress in the agricultural and rural development at a territorial level. For this purpose principal components analysis and cluster analysis were applied and the different methodological approaches reviewed. A two-stage method is also proposed. This could provide the analytical tools to simplify and interpret the results of the territorial analyses, also in order to supply a flexible instrument to policy-makers. A case-study on the Emilia-Romagna region, in Italy, is presented.

description: Image classification is central to the big data revolution in medicine. Improved information processing methods for diagnosis and classification of digital medical images have shown to be successful via deep learning approaches. As this field is explored, there are limitations to the performance of traditional supervised classifiers. This paper outlines an approach that is different from the current medical image classification tasks that view the issue as multi-class classification. We performed a hierarchical classification using our Hierarchical Medical Image classification (HMIC) approach. HMIC uses stacks of deep learning models to give particular comprehension at each level of the clinical picture hierarchy. For testing our performance, we use biopsy of the small bowel images that contain three categories in the parent level (Celiac Disease, Environmental Enteropathy, and histologically normal controls). For the child level, Celiac Disease Severity is classified into 4 classes (I, IIIa, IIIb, and IIIC).

description: Market reforms implemented in Poland, especially broader openness to international trade, should result in increasing price integration between Polish and world markets for such internationally traded commodities like wheat. However, in a period of economic transformation, Polish agricultural prices have been very volatile which led to government intervention in the market. Mainly because of such practises, Polish monthly wheat prices were found, using regression and cointegration analysis, to be generally unrelated to selected world prices over the period of 1990/91 through 1996/97. The intervention also caused such market distortions as deviations of prices from a normally expected seasonal pattern.

description: The bright gamma-ray burst GRB050525a has been detected with the Swift observatory, providing unique multiwavelength coverage from the very earliest phases of the burst. The X-ray and optical/UV afterglow decay light curves both exhibit a steeper slope ~0.15 days after the burst, indicative of a jet break. This jet break time combined with the total gamma-ray energy of the burst constrains the opening angle of the jet to be 3.2 degrees. We derive an empirical `time-lag' redshift from the BAT data of z_hat = 0.69 +/- 0.02, in good agreement with the spectroscopic redshift of 0.61. Prior to the jet break, the X-ray data can be modelled by a simple power law with index alpha = -1.2. However after 300 s the X-ray flux brightens by about 30% compared to the power-law fit. The optical/UV data have a more complex decay, with evidence of a rapidly falling reverse shock component that dominates in the first minute or so, giving way to a flatter forward shock component at later times. The multiwavelength X-ray/UV/Optical spectrum of the afterglow shows evidence for migration of the electron cooling frequency through the optical range within 25000 s. The measured temporal decay and spectral indices in the X-ray and optical/UV regimes compare favourably with the standard fireball model for Gamma-ray bursts assuming expansion into a constant density interstellar medium.

description: Fresh blueberries are sold through a marketing cooperative of the blueberry industry in Mississippi and Louisiana. Blueberry producers have numerous alternatives in assembling blueberries, and the cooperative needs to know the costs of different systems for assembling berries in order to provide better services to its members. The main objective of this study was to determine an efficient system for handling blueberries in Mississippi and Louisiana. Sixteen models with different combinations of drop stations and shipping points were evaluated. The results of this study will help the Miss-Lou Association and farmers to better develop strategies for handling and marketing blueberries in the future. It will assist the Miss-Lou Association in determining the number, size, and locations of drop stations/shipping points with change in production each year.

description: Machine-learning algorithms have shown promise for streamflow forecasts, reservoir operations, and scheduling, but have exhibited lower accuracy in predicting extended time horizons of peak storage volume (PSV). Deep learning algorithms exhibited improved inflow forecasting accuracy, but existing research has been mostly limited to real-time operation and short-term planning. We evaluate a new approach based on a hybrid ResCNN-LSTM Encoder-Decoder algorithm, enabling long-term multi-step reservoir forecasts. The proposed approach provides a three-month, weekly averaged prediction of reservoir storage volume (RSV) during the runoff season based on historical snow water equivalent (SWE). The optimal architecture and hyper-parameters for the model are configured through five-fold cross validation resulting in a twelve-layered residual convolutional neural network (ResCNN) as the encoder and a four-layered long short-term memory (LSTM) neural network as the decoder. We evaluate the algorithm using 30 years of RSV and SWE data at the Upper Stillwater Reservoir located in Utah. The most accurate long-term predictions occurred during periods of large runoff (in excess of 28,000 ac-ft). The periods where the model performed the worst were during small runoff and late-season SWE accumulation. We find that the ResCNN-LSTM consistently outperforms three widely used statistical models, with an average PSV absolute percent error of 2.66% for the proposed algorithm compared to SARIMA (14.22%), TBATS (13.82%), and VAR (18.14%).

description: An increasing number of farmers in the United States are finding more opportunity to participate in value-added activities beyond their commodity production. Issues' such as low farm income, increasing marketing margins, and a desire to enhance demand for local commodities-generate more interest in identifying suitable value-added activities. Many states are providing programs to help promote and support farmers interested in leading the development of new food products. This paper examines the objectives and development strategies of several value-added state programs. Special attention is paid to the extent to which the programs create opportunities for farmers in different income groups. Programs profiled in this research include Iowa's Rural Economic Value-Added Mentoring Program (REVAMP), North Dakota's Agricultural Utilization Research Institute (AURI), Minnesota's Agricultural Products Utilization Commission (APUC), and other centers and programs in Colorado, Tennessee, Mississippi, and Oklahoma. A survey is conducted of the center directors to provide a profile of each program's scope and state's objectives, development strategy, and performance measures. This paper assesses the effectiveness of variously structured value-added programs as stated by the survey; it also summarizes recommended strategies for improvement. Cost considerations and long-term justification of these value-added centers is also considered. Institutional design, recommendations, central policy issues, and program performance measures are discussed. States considering the implementation or expansion of such programs will want to evaluate their design based on these findings.

description: A challenge still to be overcome in the field of visual perception for vehicle and robotic navigation on heavily damaged and unpaved roads is the task of reliable path and obstacle detection. The vast majority of the researches have as scenario roads in good condition, from developed countries. These works cope with few situations of variation on the road surface and even fewer situations presenting surface damages. In this paper we present an approach for road detection considering variation in surface types, identifying paved and unpaved surfaces and also detecting damage and other information on other road surface that may be relevant to driving safety. We also present a new Ground Truth with image segmentation, used in our approach and that allowed us to evaluate our results. Our results show that it is possible to use passive vision for these purposes, even using images captured with low cost cameras.

description: In recent years, convolutional neural networks have demonstrated promising performance in a variety of medical image segmentation tasks. However, when a trained segmentation model is deployed into the real clinical world, the model may not perform optimally. A major challenge is the potential poor-quality segmentations generated due to degraded image quality or domain shift issues. There is a timely need to develop an automated quality control method that can detect poor segmentations and feedback to clinicians. Here we propose a novel deep generative model-based framework for quality control of cardiac MRI segmentation. It first learns a manifold of good-quality image-segmentation pairs using a generative model. The quality of a given test segmentation is then assessed by evaluating the difference from its projection onto the good-quality manifold. In particular, the projection is refined through iterative search in the latent space. The proposed method achieves high prediction accuracy on two publicly available cardiac MRI datasets. Moreover, it shows better generalisation ability than traditional regression-based methods. Our approach provides a real-time and model-agnostic quality control for cardiac MRI segmentation, which has the potential to be integrated into clinical image analysis workflows.

description: We discuss a method of solving $n^{th}$ order scalar ordinary differential equations by extending the ideas based on the Prelle-Singer (PS) procedure for second order ordinary differential equations. We also introduce a novel way of generating additional integrals of motion from a single integral. We illustrate the theory for both second and third order equations with suitable examples. Further, we extend the method to two coupled second order equations and apply the theory to two-dimensional Kepler problem and deduce the constants of motion including Runge-Lenz integral.

Social justice pedagogy and teacher-student activism : a collaborative study of school-based projects
Creators: name: Lund, Darren E.
Publisher: name: University of British Columbia
Year: 2009

description: This research seeks a clearer understanding of the field of social justice education in Canada. Informed by multicultural and antiracist pedagogy, I explore the theoretical underpinnings and practical realities of this work among 11 activist Alberta teachers and students. Collaborative interviews with these participants reveal portraits of current activism in voluntary coalitions in secondary schools. Through guided critical self-reflection, fellow activists and I examine forming and sustaining ongoing projects. I present guiding hypotheses and assumptions that steer this research, and a theoretical framework that accommodates complex intersections of "race," class, gender, sexual orientation, and other considerations of social justice pedagogy and activism. This research addresses omissions in the educational literature; one such gap is a lack of research attention to young people—particularly to their role as active participants in social justice movements. In addition, I address teachers' previously undervalued role as crucial participants in educational policy development, reform efforts, and research on social justice education. Attending to the relatively few accounts of school-based action projects, I describe the integrative STOP model of student and community activism. An overview of the unique Canadian and regional contexts and recent political developments around social justice issues, and a summary of relevant research and theory from British and American literature, suggest specific areas of contention, influence, and overlap of relevance to this study. I employ a qualitative research methodology using a specific collaborative approach, and include details of participant selection, data gathering and analysis, and ethical considerations. Two chapters develop my research results along the lines traced by my guiding hypotheses. A concluding chapter outlines the specific significance of this research, factors that promote coalition-building, and promising avenues for further scholarly study. A value of this investigation is the rich offerings from my participants, whose reflections on their work are solidly grounded in understandings of daily activism. Their contributions show the potential mutual benefits of respectful research collaborations that both reveal and share the wisdom of social justice practitioners as theorists.

description: We present an overview of pulsating stars in close binaries, focusing on the question what role the dupliticity plays in triggering and/or modifying stellar oscillations and on how it can help us to interpret the oscillatory behaviour of (one of) the components. We give examples of characteristic types of oscillations observed in binaries: forced oscillations and free oscillations in both, short- and long-period binaries. The importance of studies of oscillations in eclipsing binaries is also pointed out. A list of line-profile and rapid light variables in close binaries with their basic properties is provided. No obvious relations among the orbital eccentricity, orbital frequency, rotational frequency and intrinsic frequencies of oscillations were found. The value and future prospects of asteroseismic studies of binary stars are briefly outlined while the complexity of the problem and its possible complications are also discussed.

description: The federally funded Women, Infants, and Children (WIC) program issues redeemable food instruments (or vouchers) to low-income mothers and their small children who demonstrate nutritional need. Not all such food instruments are actually redeemed. Both ethnicity and home language preferences were found to be significantly correlated with individuals' WIC food instrument redemption likelihood. However, these correlations provided little indication that any food type (except cheese for Asians) is more or less culturally acceptable to any particular ethnic or language group. Regardless of ethnicity, persons who show English as their family language preference tend to have lower food instrument redemption rates than do those who prefer to speak any other language, at least among family members. This redemption rate disparity indicates that, to induce participants to follow dietary guidelines consistent with general public health goals, even a food assistance program, such as WIC, needs to employ some marketing techniques. Use of the English language should be a major consideration in segmenting WIC markets.

description: Possibility of a ferromagnetic semiconductor single wall carbon nanotube (SWCNT), where ferromagnetism is due to coupling between doped magnetic impurity on a zigzag SWCNT and electrons spin, is investigate. We found, in the weak impurity-spin couplings, at low impurity concentrations the spin up electrons density of states remain semiconductor while the spin down electrons density of states shows a metallic behavior. By increasing impurity concentrations the semiconducting gap of spin up electrons in the density of states is closed, hence a semiconductor to metallic phase transition is take place. In contrast, for the case of strong coupling, spin up electrons density of states remain semiconductor and spin down electron has metallic behavior. Also by increasing impurity spin magnitude, the semiconducting gap of spin up electrons is increased.

description: When the College of Fine Arts Lawn went missing, a map of the lawn the size of the lawn was created to take its place. That map is illustrated on the cover of this book. It’s an arrangement of 22,500 photographs that documents the missing lawn, point for point.A map of such magnitude, however, must be abandoned. In addition to being cumbersome, it will soon yield little semblance to place it once mapped, and, not without irreverence, it is imperative the map be abandoned in due time. Hence, the purpose of this foreword is to announce the deconstruction of the map of the lawn the size of the lawn.A book of the lawn the size of the lawn will be constructed in its place. Every point of the map will become a page in the book. Co-authorship from below (i.e. readers of this book) will transform the map into a book, page by page.Consider this an invitation to author a page and dismantle the map.

description: A factor analysis examined underlying relationships of selected performance indicators for U.S. ISO 9000-registered agribusiness sites. The factoring technique uniquely identified five of six primary factors-namely, improved quality performance, better training of personnel and document control, product prices, external audits, and cost of nonconformity. A sixth ill-defined factor is also identified. Each identified factor could influence the market position and/or profitability of an ISO 9000 registered agribusiness site.
Generation of Small Neutrino Majorana Masses in a Randall-Sundrum Model

Publisher: name: arXiv
Year: 2005
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)
subject: FOS: Physical sciences

description: We propose a model, in the framework of 5D with warped geometry, in which small neutrino Majorana masses are generated by tree level coupling of lepton doublets to a SU(2)_{L}-triplet scalar field, which is coupled to a bulk SM-singlet. The neutrino mass scale is determined by the bulk mass term (alpha_{S}) of the singlet as ve^{-2(alpha_{S}-1)*pi*kR}. This suppression is due to a small overlap between the profile of the singlet zero mode and the triplet, which is confined to the TeV brane. The generic form for the neutrino mass matrix due to the overlap between the fermions is not compatible with the LMA solution. This is overcome by imposing a Z_{4} symmetry, which is softly broken by couplings of the triplet Higgs to the lepton doublets. This model successfully reproduces the observed masses and mixing angles in charged lepton sector as well as in the neutrino sector, in addition to having a prediction of |U_{e3}| ~ O(0.01). The mass of the triplet is of the order of a TeV, and could be produced at upcoming collider experiments. The doubly charged member of the triplet can decay into two same sign charged leptons yielding the whole triplet coupling matrix which, in turn, gives the mixing matrix in the neutrino sector.

description: Economic questionnaires were administered in 1997 and 1998 to farmers in the Indiana/Illinois, Kansas, and Iowa sites involved in the Areawide Pest Management (AWPM) program for the control of corn rootworms. These questionnaires provided information regarding variable and fixed costs of production for fields located within the management site and also the companion acreage. The economic analysis indicated that yields, variable costs per acre, and machinery costs per acre were not statistically different within a site across the inner core, outer ring, and companion acreage, with relatively few exceptions. This gives a solid baseline for a Net Present Value comparison between the soil insecticide and AWPM methods for control of corn rootworms, since fixed and variable costs of production not associated with corn rootworm control can be assumed to be statistically the same between the inner core, outer ring, and companion acreage. Various information regarding farming practices among the sites was obtained from the economic questionnaires, such as adoption rates of GPS (site-specific farming) and Bt corn (resistant to the European corn borer). Other observations included soil insecticide use, crop rotations, tillage types, and crop consultant use.

description: ADM was at the center of two large global price-fixing conspiracies. Buyers were overcharged $116 to $378 million in the United States. Market structure and corporate management style facilitated these cartels. The criminal prosecutions and defendants' legal strategies were both laudatory, but civil plaintiffs were short-changed. ADM has undergone severe management restructuring, but the effectiveness of apprehending global cartels with national legal enforcement is questionable.
