description: Geographic markets are extremely important to agriculture because agricultural products are bulky and/or perishable and production and consumption areas are separated. This study investigates how mandatory price reporting has influenced the degree of spatial market integration between U.S. regional fed cattle markets. Results indicate the market prices across the regional cattle markets are cointegrated. In addition, the amount of time it took for one market to react to the other market's change in price varied across the three time periods used in this study. This suggests mandatory price reporting has not substantially increased market integration.

description: Mitotic counting is a vital prognostic marker of tumor proliferation in breast cancer. Deep learning-based mitotic detection is on par with pathologists, but it requires large labeled data for training. We propose a deep classification framework for enhancing mitosis detection by leveraging class label information, via softmax loss, and spatial distribution information among samples, via distance metric learning. We also investigate strategies towards steadily providing informative samples to boost the learning. The efficacy of the proposed framework is established through evaluation on ICPR 2012 and AMIDA 2013 mitotic data. Our framework significantly improves the detection with small training data and achieves on par or superior performance compared to state-of-the-art methods for using the entire training data.

description: The mid-rapidity (dsigma_(pN)/dy at y=0) and total sigma_(pN) production cross sections of J/Psi mesons are measured in proton-nucleus interactions. Data collected by the HERA-B experiment in interactions of 920 GeV/c protons with carbon, titanium and tungsten targets are used for this analysis. The J/Psi mesons are reconstructed by their decay into lepton pairs. The total production cross section obtained is sigma_(pN)(J/Psi) = 663 +- 74 +- 46 nb/nucleon. In addition, our result is compared with previous measurements.

description: We use line-of-sight velocity information on the filamentary emission-line nebula of NGC 1275 to infer a dynamical model of the nebula's flow through the surrounding intracluster gas. We detect outflowing gas and flow patterns that match simulations of buoyantly rising bubbles from which we deduce that some of the nebula filaments have been drawn out of NGC 1275. We find a radial gradient of the ratio [NII]6584/H-alpha which may be due to a variation in metallicity, interactions with the surrounding intracluster medium or a hardening of the excitation mechanism. We find no preferred spatial correlation of stellar clusters within the filaments and there is a notable lack of [OIII]5007 emission, therefore it is unlikely that the filaments are ionized by stellar UV.

description: Hybrid encoding of quantum information is a promising approach towards the realisation of optical quantum protocols. It combines advantages of continuous variables encoding, such as high efficiencies, with those of discrete variables, such as high fidelities. In particular, entangled hybrid states were shown to be a valuable ressource for quantum information protocols. In this work, we present a hybrid entanglement witness that can be implemented on currently available experiments and is robust to noise currently observed in quantum optical set-ups. The proposed witness is based on measurements of genuinely hybrid observables. The noise model we consider is general. It is formally characterised with Kraus operators since the considered hybrid system can be expressed in a finite dimension basis. A practical advantage of the witness is that it can be tested by measuring just a few experimentally available observables.

description: We present a numerical study of the structural correlations associated to gas adsorption/desorption in silica aerogels in order to provide a theoretical interpretation of scattering experiments. Following our earlier work, we use a coarse-grained lattice-gas description and determine the nonequilibrium behavior of the adsorbed gas within a local mean-field analysis. We focus on the differences between the adsorption and desorption mechanisms and their signature in the fluid-fluid and gel-fluid structure factors as a function of temperature. At low temperature, but still in the regime where the isotherms are continuous, we find that the adsorbed fluid density, during both filling and draining, is correlated over distances that may be much larger than the gel correlation length. In particular, extended fractal correlations may occur during desorption, indicating the existence of a ramified cluster of vapor filled cavities. This also induces an important increase of the scattering intensity at small wave vectors. The similarity and differences with the scattering of fluids in other porous solids such as Vycor are discussed.

Role of Nella in Giacomo Puccini’s Gianni Schicchi

description: This Master's Thesis for the Master of Music (Opera) was the presentation of the role of NELLA in Puccini's GIANNI SCHICCHI, performed March 9 and 10, 2002 at the Chan Centre for the Performing Arts. The role of NELLA is that of one of the greedy relatives of the now deceased BUOSO DONATI, a pious Italian gentleman of considerable fortune, who has left all of his money to the church rather than his relatives. NELLA is a niece of BUOSO. NELLA is approximately 35, shrewish and greedy, with a taste for the finer things in life. The greed of the entire family is used by the title character, GIANNI SCHICCHI, to rob them of the choicer pieces of property - the mills at Signa, a mule worth 30 florins, and the house of BUOSO DONATI. SCHICCHI pretends to be BUOSO and changes the will to benefit the relatives, but at the last moment leaves the best items to himself, and the relatives can do nothing as they will have their hands cut off for forgery if they are caught. NELLA is a high soprano role, which can also be sung by a dramatic soprano, as Puccini's orchestration requires a sizable voice with easy access to the top. My voice type is dramatic coloratura, which is a combination of agility, dark colour, large size and extreme registers, so this role is ideally suited for me vocally.
Precision measurement of cosmic magnification from 21 cm emitting galaxies

description: We show how precision lensing measurements can be obtained through the lensing magnification effect in high redshift 21cm emission from galaxies. Normally, cosmic magnification measurements have been seriously complicated by galaxy clustering. With precise redshifts obtained from 21cm emission line wavelength, one can correlate galaxies at different source planes, or exclude close pairs to eliminate such contaminations. We provide forecasts for future surveys, specifically the SKA and CLAR. SKA can achieve percent precision on the dark matter power spectrum and the galaxy dark matter cross correlation power spectrum, while CLAR can measure an accurate cross correlation power spectrum. The neutral hydrogen fraction was most likely significantly higher at high redshifts, which improves the number of observed galaxies significantly, such that also CLAR can measure the dark matter lensing power spectrum. SKA can also allow precise measurement of lensing bispectrum.

Physical properties and thermal stability of Fe5GeTe2 single crystals

description: The magnetic and transport properties of Fe-deficient Fe5GeTe2 single crystals (Fe5-xGeTe2 with x~0.3) were studied and the impact of thermal processing was explored. Quenching crystals from the growth temperature has been previously shown to produce a metastable state that undergoes a strongly hysteretic first-order transition upon cooling below ~100K. The first-order transition impacts the magnetic properties, yielding an enhancement in the Curie temperature T_C from 270 to 310K. In the present work, T_HT ~550K has been identified as the temperature above which metastable crystals are obtained via quenching. Diffraction experiments reveal a structural change at this temperature, and significant stacking disorder occurs when samples are slowly cooled through this temperature range. The transport properties are demonstrated to be similar regardless of the crystal's thermal history. The scattering of charge carriers appears to be dominated by moments fluctuating on the Fe(1) sublattice, which remain dynamic down to 100-120K. Maxima in the magnetoresistance and anomalous Hall resistance are observed near 120K. The Hall and Seebeck coefficients are also impacted by magnetic ordering on the Fe(1) sublattice. The data suggest that both electrons and holes contribute to conduction above 120K, but that electrons dominate at lower temperature when all of the Fe sublattices are magnetically ordered. This study demonstrates a strong coupling of the magnetism and transport properties in Fe5-xGeTe2 and complements the previous results that demonstrated strong magnetoelastic coupling as the Fe(1) moments order.

description: We study a possibly integrable model of abelian gauge fields on a two-dimensional surface M, with volume form mu. It has the same phase space as ideal hydrodynamics, a coadjoint orbit of the volume-preserving diffeomorphism group of M, SDiff(M,mu). Gauge field Poisson brackets differ from the Heisenberg algebra, but are reminiscent of Yang-Mills theory on a null surface. Enstrophy invariants are Casimirs of the Poisson algebra of gauge invariant observables. Some symplectic leaves of the Poisson manifold are identified. The Hamiltonian is a magnetic energy, similar to that of electrodynamics, and depends on a metric whose volume element is not a multiple of mu. The magnetic field evolves by a quadratically non-linear `Euler' equation, which may also be regarded as describing geodesic flow on SDiff(M,mu). Static solutions are obtained. For uniform mu, an infinite sequence of local conserved charges beginning with the hamiltonian are found. The charges are shown to be in involution, suggesting integrability. Besides being a theory of a novel kind of ideal flow, this is a toy-model for Yang-Mills theory and matrix field theories, whose gauge-invariant phase space is conjectured to be a coadjoint orbit of the diffeomorphism group of a non-commutative space.

description: This article reports the structural and magnetic characterisation of a new hexagonal ($P6_3cm$) low-temperature phase of Ba$_3$Tb(BO$_3$)$_3$, isostructural with the heavier lanthanide borates with formula Ba$_3$Ln(BO$_3$)$_3$ (Ln = Dy-Lu). The crystal structure contains a quasi-two-dimensional (2D) triangular lattice of Tb$^{3+}$ ions and is predicted to display unusual magnetic behaviour as a result of the low dimensionality. Magnetic susceptibility $χ(T)$ shows antiferromagnetic interactions ($θ_{CW} = -7.15$ K) and no sharp ordering transition at $T \geq 2$ K, but analysis of $χ'(T)$, isothermal magnetisation and heat capacity suggests the possibility of short-range ordering at $T \approx 10$ K. The material exhibits an inverse magnetocaloric effect at $T < 4$ K.

description: We insert and manipulate a single chlorine atom in chlorine monolayer on a Si(100)-2x1 surface using a scanning tunneling microscope. Two objects were created - a Cl atom in a groove between two dimer rows, and bridge-bonded Cl on a silicon dimer. Changing the voltage polarity leads to conversion of the objects into each other. Anisotropic movement of the objects at 77 K is mediated by two different diffusion mechanisms: hopping and crowdion-like motion. Insertion of a Cl atom in a groove between two dimer rows leads to the formation of a dangling bond on a third-layer Si atom. At positive sample voltage bias, the first object is positively charged, while the second object can be neutral or negatively charged depending on silicon sample doping.

description: In recent years there has been a growing interest in universities promoting a more holistic approach to assessment and feedback. One of the best ways to gain this holistic approach is through a programme-focused approach (Jessop et al, 2014) to not only the curriculum design process, but assessment and feedback practices. A programme-focused approach can provide opportunities to support students so that they better understand how to move through their programme of study equipped with the skills needed to be self-regulated learners in both the present and the future. This means knowledge and skills are assessed in a variety of ways; assessments complement one another, and it is possible to obtain a picture of students’ broader skillsets. ‘Designing assessment programmatically can also help reduce over-assessment, as academic staff have greater visibility of the amount and type of assessment their students are required to complete’ (Learning Through Assessment, 2023). This presentation will focus on how to start incorporating programmatic approaches into your curriculum design to support students with their assessment and feedback literacy. We will look at constructively aligning intended learning outcomes to assessments, and how to map the skills that students learn throughout the programme.
Scaling of the Equilibrium Magnetization in the Mixed State of Type-II Superconductors

Year: 2004
Subjects: subject: Superconductivity (cond-mat.supr-con)

description: We discuss the analysis of mixed-state magnetization data of type-II superconductors using a recently developed scaling procedure. It is based on the fact that, if the Ginzburg-Landau parameter kappa does not depend on temperature, the magnetic susceptibility is a universal function of H/H_c2(T), leading to a simple relation between magnetizations at different temperatures. Although this scaling procedure does not provide absolute values of the upper critical fieldH_c2(T), its temperature variation can be established rather accurately. This provides an opportunity to validate theoretical models that are usually employed for the evaluation of H_c2(T) from equilibrium magnetization data. In the second part of the paper we apply this scaling procedure for a discussion of the notorious first order phase transition in the mixed state of high temperature superconductors. Our analysis, based on experimental magnetization data available in the literature, shows that the shift of the magnetization accross the transition may adopt either sign, depending on the particular chosen sample. We argue that this observation is inconsistent with the interpretation that this transition always represents the melting transition of the vortex lattice.

A Unified Approach to Enhanced Sampling

description: The sampling problem lies at the heart of atomistic simulations and over the years many different enhanced sampling methods have been suggested towards its solution. These methods are often grouped into two broad families. On the one hand methods such as umbrella sampling and metadynamics that build a bias potential based on few order parameters or collective variables. On the other hand, tempering methods such as replica exchange that combine different thermodynamic ensembles in one single expanded ensemble. We instead adopt a unifying perspective, focusing on the target probability distribution sampled by the different methods. This allows us to introduce a new class of collective-variables-based bias potentials that can be used to sample any of the expanded ensembles normally sampled via replica exchange. We also provide a practical implementation, by properly adapting the iterative scheme of the recently developed on-the-fly probability enhanced sampling method [Invernizzi and Parrinello, J. Phys. Chem. Lett. 11.7 (2020)], which was originally introduced for metadynamics-like sampling. The resulting method is very general and can be used to achieve different types of enhanced sampling. It is also reliable and simple to use, since it presents only few and robust external parameters and has a straightforward reweighting scheme. Furthermore, it can be used with any number of parallel replicas. We show the versatility of our approach with applications to multicanonical and multithermal-multibaric simulations, thermodynamic integration, umbrella sampling, and combinations thereof.
Inelastic scattering effects and the Hall resistance in a 4-probe ring

description: Phase randomizing processes in mesoscopic systems can be described in a phenomenological way within the Landauer-Büttiker formalism by attaching extra voltage probes to the sample. In this paper, it is shown that a perturbation treatment of this idea allows for the incorporation of such effects without the need of giving up the efficiency of recursive techniques commonly used for calculating the transmission coefficients. The technique is applied to a 4-probe ring, where a Hall effect can be observed that originates from quantum interference rather than a Lorentz force acting on the electrons. The influence of inelastic scattering on both the Hall resistance and the Aharonov-Bohm oscillations in the longitudinal resistance are examined.

description: We study deep neural networks with binary activation functions (BDNN), i.e. the activation function only has two states. We show that the BDNN can be reformulated as a mixed-integer linear program which can be solved to global optimality by classical integer programming solvers. Additionally, a heuristic solution algorithm is presented and we study the model under data uncertainty, applying a two-stage robust optimization approach. We implemented our methods on random and real datasets and show that the heuristic version of the BDNN outperforms classical deep neural networks on the Breast Cancer Wisconsin dataset while performing worse on random data.

description: As success is achieved in raising agricultural output and incomes in general, increased attention is being paid to improving the incomes and nutritional status of the lower-income, more disadvantaged peoples. Food subsidies have become an increasingly important means of transferring income to the poor. Because low-income people spend a much higher proportion of their income on food, food is a relatively efficient area for use of subsidies. They increase nutritional status more than other sources of income (see IFPRI Research Report 5, Impact of Subsidies Rice on Food Consumption and Nutrition in Kerala, by Shubh Kumar), and they have greater political acceptance among those with higher incomes, making them an attractive means if innocent transfer. However, there are also serious fiscal policy problems associated with food subsidies, as IFPRI’s current research in Egypt where food subsidies are unusually large, has shown. Precisely because food subsidies attack a poverty problem of immense size, they can easily expand to the point where they prejudge other designed to increased future incomes of the poor. Thus research is needed to provide knowledge for increasing the efficiency of food subsidies in meeting their various objectives. This study by Cheryl Williamson Gray uses a detail, large-scale consumer budget survey of Brazil to shed light on these problems. It measures differences in consumption pattern among people in different region and income group as a basis for measuring the comparative effectiveness of subsidies levied on different types of food. The study shows that the commodity chosen for emphasis in a subsidy program has a major effect on who benefits and by how much and hence its efficiency in reaching particular equity objectives. From this base a variety of policy analysis are carried out. The International Food Policy Research Institute has a distinguished record of studies in this area, most notably those on India, Bangladesh, and Sri Lanka. A major study is under way in Egypt. Other work is examining the effects of rural employment schemes, a common rural analog to food subsidies, which tends to be urban oriented. Thus IFPRI is constructing a base for a major comparative income, food consumption, and the nutritional status of both rural and urban people. Cheryl Williamson Gray’s study is an important building block in this continuing effort.

description: Multi-epoch GHz Very Long Baseline Interferometry (VLBI) data of the radio-loud quasar J1101+7225 were analyzed to estimate the proper motion of extended optically thin jet components. Two components separated from the core could be mapped at 1.66 GHz, which is consistent with earlier observations. In one case we found evidence of high apparent superluminal motion (beta_app= 22.5+/-4) at large (deprojected) distances to the core (22 mas ~ 4 kpc at z= 1.46). Typically in other quasars such high separation velocities are only found much closer to the core component. Furthermore the Doppler factor, the magnetic field strength, and the angular size of the optically thick core were derived using published X-ray data. Analysis of 5 GHz VLBI data reveals the existence of further jet components within the central 5 mas. Additionally the data published so far on the GHz-spectrum were discussed at all angular resolutions. J1101+7225 turns out to be a standard quasar for studying different aspects of radio jet kinematics out to kpc-scales.

description: The International Food Policy Research Institute, as part of the Conservative Group on International Agricultural Research, is profoundly concern about the new agricultural technology and the policies needed to encourage its adoption and increase its effectiveness in meeting major societal objectives. The spread of high-yielding varieties depends greatly on increased in fertilizer availability to farmers. Likewise, continued rapid growth in fertilizer uses depends on new crops varieties that can provide greater yields in response to larger doses of fertilizer. It is clear that during the next few decades the food supplies necessary to meet even minimum expected rates of population growth and growth in per capita income cannot be realized without the development of this symbiotic fertilizer research relationship. In this research report, Gunvant M. Desai demonstrates that growth in fertilizer uses is a complex function of many variables that must be seen in relation to each other if an effective expansionary policy is to be developed. He notes that in the past there has been a lack of understanding of the importance of ample, assured supplies of fertilizer use will not be possible, and fertilizers will be confined to the crops and places where they have been most profitable in the past. He suggest that growth in fertilizer use has been constrained by the role of foreign assistance in financing fertilizer imports for developing countries, the large fluctuations in the size and timing of such foreign exchange availability due to change in export demands and prices. This has been exacerbated by deficiencies in administration of fertilizer supplies. Desai analyzes these and other issues through the Indian experience. He provides a basis for understanding that experience and developing policies to continue fertilizer growth in India in the face of the more difficult economic environment for fertilizer use. Perhaps most valuable, this research provides a model for similar in dept analyses in other countries. Desai has spent almost 20 years exploring the complex factors of fertilizer use, which his study reflects in its thorough and highly integrated approach. This analysis will be followed by another research report that will be followed by another research report that will include a comparison of other intensive analyses at the country level.
Myosin light chain phosphorylation facilitates in vivo myosin filament reassembly after mechanical perturbation

description: It is generally believed that the myosin thick filaments in smooth muscle are structurally less stable than those in striated muscle. In vitro studies have shown that phosphorylation of the 20-kD myosin light chain (MLC) facilitates formation of the thick filaments from monomeric myosins in solution. It appears that the structural integrity of the thick filaments can be enhanced by phosphorylation of the MLC. It is however not known whether the transition from monomeric to filamentous myosin occurs in intact smooth muscle when the light chains are phosphorylated during muscle activation. The physiological significance of the thick filament lability and the role of MLC phosphorylation in modulating the filament integrity in intact smooth muscle are still being debated. It has been shown in our laboratory that mechanical strain is able to induce partial dissolution of unphosphorylated myosin thick filaments in intact smooth muscle; repolymerization of the thick filaments occurs when the muscle is subjected to cycles of contraction and relaxation. The objective of my thesis research is to determine whether MLC phosphorylation is required for repolymerization of the thick filaments after they have been partially disassembled by mechanical agitation. We used the conventional electron microscopy to quantify the cross-sectional density of myosin thick filaments in airway smooth muscle; partial dissolution of the thick filaments was induced by applying length oscillations to the muscle preparation; recovery of the thick filament density after oscillation was examined in the presence and absence of wortmannin, a potent inhibitor of myosin light chain kinase (MLCK). The results showed that isometric force production in airway smooth muscle was totally dependent on MLC phosphorylation. The inhibition of MLC phosphorylation alone did not cause disassembly of myosin filaments. The unphosphorylated thick filaments however partially dissolved when the muscle was subjected to oscillatory strains, as evidenced by a 25% decrease in the filament density. The post-oscillation filament density did not recover when wortmannin was present; it recovered to the pre-oscillation level when wortmannin was removed. Based on the above findings, we conclude that thick filament formation in vivo is MLC phosphorylation dependent.

description: Neuronal networks provide living organisms with the ability to process information. They are also characterized by abundant recurrent connections, which give rise to strong feedback that dictates their dynamics and endows them with fading (short-term) memory. The role of recurrence in long-term memory, on the other hand, is still unclear. Here we use the neuronal network of the roundworm C. elegans to show that recurrent architectures in living organisms can exhibit long-term memory without relying on specific hard-wired modules. A genetic algorithm reveals that the experimentally observed dynamics of the worm's neuronal network exhibits maximal complexity (as measured by permutation entropy). In that complex regime, the response of the system to repeated presentations of a time-varying stimulus reveals a consistent behavior that can be interpreted as soft-wired long-term memory.

description: A possibility for a new family of intermetallic perovskite superconductors Sc3XB, with X = Tl, In, Ga and Al, is presented as a result of KKR electronic structure and pseudopotential phonon calculations. The large values of computed McMillan--Hopfield parameters on scandium suggest appearance of superconductivity in Sc3XB compounds. On the other hand, the possibility of weak itinerant ferromagnetic behavior of Sc3X systems is indicated by the small magnetic moment on Sc atoms in two cases of X =~ l and In. Also the electronic structure and resulting superconducting parameters for more realistic case of boron--deficient systems Sc3XB_x are computed using KKR--CPA method, by replacing boron atom with a vacancy. The comparison of the calculated McMillan--Hopfield parameters of the Sc3XB series with corresponding values in MgCNi3 and YRh3B superconductors is given, finding the favorable trends for superconductivity.

description: Detailed investigations about consumer food practices provide interesting information concerning the different manners consumers think about their own behaviors. Considering that consumers have objectives and different anxieties in terms of food that may result in distinct food models, this paper proposes a low-fat consumer typology. The main goal of this work was to better understand the profile of both consumer types (low-fat and non low fat consumers). A survey was applied about consumption frequency, reasons that lead to his/her acceptation or rejection of low fat products and their opinions about what it means to eat well. Recognizing an extensive data set of qualitative variables, multivariate statistical analyses was adopted. Moreover, a lexical analysis was applied so as to interpret the content of survey. It was concluded that low-fat consumers who accept such products are concerned with health and physical shape and non low-fat consumers who reject such products have stated doubts in terms of their efficacy.

description: Our goal, in this research, was to describe the perception of the image of a supermarket of the city of Belo Horizonte for its consumers. Studies regarding the image in the marketing environment and in special in the retail market, already come being carried through since the last half of century XX. In its theoretical base are evidenced the main authors who study the retail market and also bring the theoretical contribution of the relation of the image and organization, starting from the classic article written for Pierre Martineau “The personality of the Retail Store”. It presents a descriptive research carried through questions structuralized and halfstructuralized the consumers of a supermarket, for verification of the perception of the image of this supermarket. The presented results demonstrate that the intrinsic aspects to the organization can influence the behavior of its consumers and that these aspects must be seen as a differential of market to be explored in this segment of the food retail. In the conclusion, the final consideration on the accomplished research and the suggestions about the reached results of research are presented.
