description: This paper assesses the role that cereal markets have played in stimulating farm-level productivity growth and marketing of staple foods, in responding to changing demand patterns, in satisfying minimum food security needs, and in contributing to poverty reduction in both urban areas (through reductions in food prices) and rural areas (through increases in farm incomes). The paper uses a case study approach based on the Malian experience. Mali presents a particularly good case study of cereal market development because of (1) a unique approach to donor and government coordination during the early stages of market liberalization, (2) the contrasting development paths of the irrigated rice and the rainfed coarse grains subsectors, (3) Mali’s growing role in West Africa’s regional cereal trade, and (4) on-going policy debates that are relevant to the entire region. These policy debates include questions such as (1) how to balance consumer and producer interests via trade, tax, and safety net policies, (2) how to shape land policies that encourage a mix of family and commercial farms capable of meeting both national food production goals and poverty reduction objectives, and (3) how to provide incentives that reduce rural poverty by assisting resource poor farmers while also stimulating greater productivity among better-off farmers.
Heart failure self-monitoring toolkit
Creators: name: Green, Tanya
Publisher: name: University of Massachusetts Amherst
Year: 2015

Heart Failure (HF) is one of the most common cardiac syndromes encountered in the primary care setting amongst older adults; it affects more than 6 million people in the United States (Goroll & Mulley, 2009; Papasifakis, n.d.).  HF is one of the most common diagnosis of patient readmissions.  HF readmissions increase the cost of healthcare and affect the quality of life for individuals.  Different strategies such as disease management programs with a focus on patient education have been widely used to reduce the risk of patient readmissions.   Evidence-based research has shown that heart failure disease management programs that focus on patient education and telephone follow-up decrease the probability of patient readmissions and increase the individual’s quality of life.  In Puerto Rico, there is a dearth of research in heart failure disease management programs and the effectiveness of advanced practice nurses in the management and treatment of patients with heart failure. The purpose of this toolbox is to provide a standardized program for veterans that have had a recent hospital admission (30 days or less) with a diagnosis of decompensated heart failure at the VA Caribbean Healthcare System in San Juan, Puerto Rico.

description: This paper presents the identification of galaxy clusters from the photometric redshift catalog based on three imaging surveys of SCUSS, SDSS, and unWISE. By applying a fast clustering algorithm, we obtain a total of 19,610 clusters in the redshift range of $0.05 < z < 0.65$ over a sky area of about 3,700 deg$^2$ in the south Galactic gap. Monte Carlo simulations show that the false detection rate is about 8.9\%. The redshift uncertainty is estimated to be about 0.013. The mass and richness of detected clusters are derived through the calibration based on the measurements of X-ray emission and Sunyaev--Zel'dovich effect.

description: Wheat consumption in Sub-Saharan Africa (SSA) is increasing rapidly, faster than any other major food grain. Between 2000 and 2009, per capita wheat consumption in SSA increased at a rate of 0.35 kilogram (kg)/year, outpacing maize and rice. Total wheat consumption increased by nearly 650,000 Metric tons (MT)/year. Staple grain consumption in Sub-Saharan Africa is rising at the same time that the region is becoming more dependent on imported staples. Wheat consumed in SSA is increasingly coming from imports from non-SSA countries as wheat production in SSA has failed to keep up with growing demand. Africa’s growing reliance on imported staples including wheat received a great deal of attention in the 1980s and 1990s, yet there has been relatively little research on this issue in recent years. This paper takes stock of trends in wheat consumption and net imports in SSA since 1980, and identifies the drivers of growing demand for wheat at country-level in SSA. It also discusses the potential dilemmas posed by SSA’s increasing reliance on imported staples, and examines the pros and cons of various options for African countries to meet their staple grain needs.

description: A pilot Intensive Agricultural Development Program, popularly known as IADP, or Package Program, was undertaken by India in cooperation with the Ford Foundation in 1960. It was designed for participation by all farmers in selected districts. Assistance in adoption of a locally adapted "package" of improved technology was to be combined with adequate supplies of fertilizer and other inputs, credit to buy them, and assurance of remunerative prices. The program was only partially implemented and many unforeseen problems were encountered, but considerable progress was made before the advent of higher yielding seeds. The program has led in adoption of new research results, including the new seeds.

Dark matter and visible baryons in M33

Publisher: name: arXiv
Year: 2003
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: In this paper we present new measurements of the gas kinematics in M33 using the CO J=1-0 line. The resulting rotational velocities complement previous 21-cm line data for a very accurate and extended rotation curve. The implied dark matter mass, within the total gaseous extent, is a factor 5 higher than the visible baryonic mass. Dark matter density profiles with an inner cusp as steep as R^{-1}, are compatible with M33 data. The dark matter concentrations required for fitting the M33 rotation curve are very low but marginally consistent with halos forming in a standard Cold Dark Matter cosmology. The M33 virialized dark halo is at least 50 times more massive than the visible baryons and its size is comparable with the M33-M31 separation. Inner cusps as steep as R^{-1.5} are ruled out, while halo models with a large size core of constant density are consistent with the M33 data. A central spheroid of stars is needed and we evaluate its dynamical mass range. Using accurate rotational velocity gradients and the azimuthally averaged baryonic surface densities, we show that a disk instability can regulate the star formation activity in M33. Considering the gaseous surface density alone, the predicted outer star formation threshold radius is consistent with the observed drop of the H-alpha surface brightness if a shear rate criterion is used. The classical Toomre criterion predicts correctly the size of the unstable region only when the stellar or dark halo gravity, derived in this paper, is added to that of the gaseous disk.

description: Using lattice quantum chromodynamics (QCD) we perform an unquenched calculation of the gluon propagator in Landau gauge. We use configurations generated with the AsqTad quark action by the MILC collaboration for the dynamical quarks and compare the gluon propagator of quenched QCD (i.e., the pure Yang-Mills gluon propagator) with that of 2+1 flavor QCD. The effects of the dynamical quarks are clearly visible and lead to a significant reduction of the nonperturbative infrared enhancement relative to the quenched case.

description: We present MAESTROeX, a massively parallel solver for low Mach number astrophysical flows. The underlying low Mach number equation set allows for efficient, long-time integration for highly subsonic flows compared to compressible approaches. MAESTROeX is suitable for modeling full spherical stars as well as well as planar simulations of dynamics within localized regions of a star, and can robustly handle several orders of magnitude of density and pressure stratification. Previously, we have described the development of the predecessor of MAESTROeX, called MAESTRO, in a series of papers. Here, we present a new, greatly simplified temporal integration scheme that retains the same order of accuracy as our previous approaches. We also explore the use of alternative spatial mapping of the one-dimensional base state onto the full Cartesian grid. The code leverages the new AMReX software framework for block-structured adaptive mesh refinement (AMR) applications, allowing for scalability to large fractions of leadership-class machines. Using our previous studies on the convective phase of single-degenerate progenitor models of Type Ia supernovae as a guide, we characterize the performance of the code and validate the new algorithmic features. Like MAESTRO, MAESTROeX is fully open source.

description: The $SU(N_f)_L \otimes SU(N_f)_R$ chiral symmetry of QCD is of central importance for the nonperturbative low-energy dynamics of light quarks and gluons. Lattice field theory provides a theoretical framework in which these dynamics can be studied from first principles. The implementation of chiral symmetry on the lattice is a nontrivial issue. In particular, local lattice fermion actions with the chiral symmetry of the continuum theory suffer from the fermion doubling problem. The Ginsparg-Wilson relation implies Lüscher's lattice variant of chiral symmetry which agrees with the usual one in the continuum limit. Local lattice fermion actions that obey the Ginsparg-Wilson relation have an exact chiral symmetry, the correct axial anomaly, they obey a lattice version of the Atiyah-Singer index theorem, and still they do not suffer from the notorious doubling problem. The Ginsparg-Wilson relation is satisfied exactly by Neuberger's overlap fermions which are a limit of Kaplan's domain wall fermions, as well as by Hasenfratz and Niedermayer's classically perfect lattice fermion actions. When chiral symmetry is nonlinearly realized in effective field theories on the lattice, the doubling problem again does not arise. This review provides an introduction to chiral symmetry on the lattice with an emphasis on the basic theoretical framework.

Yet, after more than a decade of input subsidies, rural poverty rates have remained persistently high at around 80%. Poor targeting of FISP inputs may partially explain the lack of progress on addressing persistently high rural poverty levels over the last decade.

A Small-Change Approach to Weight Loss In Obese Adult Patients: A Research Translation Project
Creators: name: Beck, Aimee B
Publisher: name: University of Massachusetts Amherst
Year: 2015

Abstract
Obesity is a major health threat in the United States. Excess weight can have devastating effects on an individual’s overall health and well-being. This research translation project utilized the 12-week small-change approach to weight loss as an intervention, which is shown to be feasible and beneficial for weight loss. This intervention has been successful in the ASPIRE-VA pilot study with 14 sedentary, obese middle-aged male and female veterans (Damschroder, Lutes, Goodrich, Gillon, & Lowry, 2009). For this project the intervention was implemented in a family practice office in Gardner, Massachusetts. Ten female, predominantly Caucasian, participants volunteered to participate in this project in response to mailings and office flyers that were used to recruit eligible participants. The results included a significant weight loss in pounds, decrease in BMI, decreased waist circumference (in inches), and a decrease in systolic blood pressure readings. There was also a significant decrease in consumption of fast food at 12 weeks compared to baseline. Satisfaction with life scores increased post-intervention compared to pre-intervention. There was no significant change in fruit and vegetable consumption from baseline to 12 weeks. Although there was not a significant change observed in consumption of sugary sweetened beverages, most participants did not drink these beverages at baseline. There was no significant change in SF-12 health survey results pre-and post-intervention. There was no significant change in number of days per week an individual ate breakfast or exercised. Further studies are needed on weight loss interventions that are feasible in primary care patient settings.

Non-classical current noise and light emission of an ac-driven tunnel junction

description: The non-symmetrized current noise is crucial for the analysis of light emission in nanojunctions. The latter represent non-classical photon emitters whose description requires a full quantum approach. It was found experimentally that light emission can occur with a photon energy exceeding the applied dc voltage, which intuitively should be forbidden due to the Pauli principle. This overbias light emission cannot be described by the single-electron physics, but can be explained by two-electron or even three-electron processes, correlated by a local resonant mode in analogy to the well-known dynamical Coulomb blockade (DCB). Here, we obtain the non-symmetrized noise for junctions driven by an arbitrarily shaped periodic voltage. We find that when the junction is driven, the overbias light emission exhibits intriguingly different features compared to the dc case. In addition to kinks at multiples of the bias voltage, side kinks appear at integer multiples of the ac driving frequency. Our work generalizes the DCB theory of light emission to driven tunnel junctions and opens the avenue for engineered quantum light sources, which can be tuned purely by applied voltages.

description: M82 B is an old starburst site located in the eastern part of the M82 disc. We derive the distributions of age and metallicity of the star clusters located in this region of M82 by using theoretical evolutionary population synthesis models. Our analysis is based on the comparison of the $BVIJ$ photometry obtained by de Grijs et al. (2001) with the colours of single-generation stellar populations. We show that M82 B went through a chemical enrichment phase up to super-solar metallicities around the time of the last close encounter between M82 and its large neighbour galaxy M81. We date and confirm the event triggering the enhanced cluster formation at about 1 Gyr ago. At almost the same time an additional, distinct subpopulation of metal-poor clusters formed in the part of M82 B nearest to the galactic centre. The formation of these peculiar clusters may be related to infall of circumgalactic gas onto M82 B.

description: Abstract

This study examines the relationship between intermediate EFL learners' writing performance and their lexical and grammatical knowledge. While previous research has explored the individual effects of vocabulary and grammar on writing, few studies have investigated their combined influence. This study seeks to determine whether grammatical or lexical knowledge plays a more significant role in predicting writing performance. A sample of 100 Iranian intermediate EFL learners was selected based on their scores on the Cambridge Placement Test. Participants completed grammar and vocabulary assessments, followed by a writing task evaluated by two independent raters. Pearson correlation and regression analyses were conducted to measure the relationships among the variables. The findings revealed a significant correlation between both grammatical and lexical knowledge with writing performance, with lexical knowledge displaying a slightly stronger predictive value. This suggests that while grammar is essential for structuring coherent sentences, lexical knowledge is more influential in determining the overall quality of writing. The study supports previous research emphasizing the importance of vocabulary in second language acquisition, highlighting its role in enhancing learners’ writing proficiency. These findings have pedagogical implications for EFL instruction, suggesting that language teachers should place a balanced emphasis on both vocabulary acquisition and grammar instruction. Providing learners with extensive exposure to academic vocabulary, along with opportunities for contextualized grammar practice, may improve their writing proficiency. Future research could explore additional variables, such as cognitive factors or writing strategies, that may contribute to EFL learners' writing development.

description: In this Letter we discuss the issues of the graceful exit from inflation and of matter creation in the context of a recent scenario \cite{RHBrev} in which the back-reaction of long wavelength cosmological perturbations induces a negative contribution to the cosmological constant and leads to a dynamical relaxation of the bare cosmological constant. The initially large cosmological constant gives rise to primordial inflation, during which cosmological perturbations are stretched beyond the Hubble radius. The cumulative effect of the long wavelength fluctuations back-reacts on the background geometry in a form which corresponds to the addition of a negative effective cosmological constant to the energy-momentum tensor. In the absence of an effective scalar field driving inflation, whose decay can reheat the Universe, the challenge is to find a mechanism which produces matter at the end of the relaxation process. In this Letter, we point out that the decay of a condensate representing the order parameter for a ``flat'' direction in the field theory moduli space can naturally provide a matter generation mechanism. The order parameter is displaced from its vacuum value by thermal or quantum fluctuations, it is frozen until the Hubble constant drops to a sufficiently low value, and then begins to oscillate about its ground state. During the period of oscillation it can decay into Standard Model particles similar to how the inflaton decays in scalar-field-driven models of inflation.

description: We use density-functional theoretical methods to examine the recent prediction, based on a mean-field solution of the Zener model, that diamond doped by Mn (with spin S=5/2) would be a dilute magnetic semiconductor that remains ferromagnetic well above room temperature. Our findings suggest this to be unlikely, for four reasons: (1) substitutional Mn in diamond has a low-spin S=1/2 ground state; (2) the substitutional site is energetically unfavorable relative to the much larger "divacancy" site; 3) Mn in the divacancy site is an acceptor, but with only hyperdeep levels, and hence the holes are likely to remain localized; (4) the calculated Heisenberg couplings between Mn in nearby divacancy sites are two orders of magnitude smaller than for substitutional Mn in germanium.

description: We report studies of charge-independent (CI) and charge-dependent (CD) two-particle differential number correlation functions, $R_{2} \left( Δη, Δφ\right)$, and transverse momentum correlation functions, $P_2 \left( Δη, Δφ\right)$ of charged particles produced in \PbPb\ collisions at the LHC centre-of-mass energy $\sqrt{s_{\rm NN}} =$ 2.76 TeV with the UrQMD, AMPT and EPOS models. Model predictions for $R_2$ and $P_2$ correlation functions are presented for inclusive charged hadrons ($h^\pm$) in selected transverse momentum ranges and with full azimuthal coverage in the pseudorapidity range $|η|< 1.0$. We compare these predictions for the strength, shape, and particularly the width of the correlation functions with recent measurements of these observables by the ALICE collaboration. Our analysis indicate that comparative studies of $R_2$ and $P_2$ correlation functions provide valuable insight towards the understanding of particle production in Pb--Pb collisions. We find, in particular, that these models have quantitatively different predictions for these three observables but none reproduce the measured correlation functions reported by the ALICE collaboration. Accounting for quantum number conservation in models, particularly charge conservation, is mandatory to reproduce the detailed measurements of number and transverse momentum correlation functions.

description: We present results from a series of hydrodynamic simulations investigating ram pressure stripping of galactic haloes as the host galaxy falls radially into a cluster. We perform a parameter study comprising of variations in initial gas content, gas injection rate (via stellar mass loss processes), galaxy mass and amplitude of infall. From the simulation results we track variations in both physical quantities (e.g. gas mass) and directly observable quantities (e.g. X-ray luminosities). The luminosity of the galaxy's X-ray halo is found to compare favourably with the observationally determined correlation with optical blue band luminosity (L_X:L_B) relation. Factors affecting the X-ray luminosity are explored and it is found that the gas injection rate is a dominant factor in determining the integrated luminosity. Observational properties of the material stripped from the galaxy, which forms an X-ray wake, are investigated and it is found that wakes are most visible around galaxies with a substantial initial gas content, during their first passage though the cluster. We define a statistical skewness measure which may be used to determine the direction of motion of a galaxy using X-ray observations. Structures formed in these simulations are similar to the cold fronts seen in observation of cluster mergers where a sharp increase in surface brightness is accompanied by a transition to a cooler region.

description: In regional income comparisons, relative and absolute measures sometimes produce apparently contradictory results. These can be reconciled if a proper time perspective is utilized. An income gap between regions, relative or absolute, indicates the situation at a particular time, while growth rates and changes in proportions point to long-run implications. As long as a regional growth rate exceeds the national rate, the absolute regional income gap may increase or decrease in the short run, but in the long run the ratio of per capita incomes must approach unity and the income gap must approach zero.

description: In the past years, large particle-physics experiments have shown that muon rate variations detected in underground laboratories are sensitive to regional, middle-atmosphere temperature variations. Potential applications include tracking short-term atmosphere dynamics, such as Sudden Stratospheric Warmings. We report here that such sensitivity is not only limited to large surface detectors under high-opacity conditions. We use a portable muon detector conceived for muon tomography for geophysical applications and we study muon rate variations observed over one year of measurements at the Mont Terri Underground Rock Laboratory, Switzerland (opacity of ~700 meter water equivalent). We observe a direct correlation between middle-atmosphere seasonal temperature variations and muon rate. Muon rate variations are also sensitive to the abnormal atmosphere heating in January-February 2017, associated to a Sudden Stratospheric Warming. Estimates of the effective temperature coefficient for our particular case agree with theoretical models and with those calculated from large neutrino experiments under comparable conditions. Thus, portable muon detectors may be useful to 1) study seasonal and short-term middle atmosphere dynamics, especially in locations where data is lacking such as mid-latitudes; and 2) improve the calibration of the effective temperature coefficient for different opacity conditions. Furthermore, we highlight the importance of assessing the impact of temperature on muon rate variations when considering geophysical applications. Depending on latitude and opacity conditions, this effect may be large enough to hide subsurface density variations due to changes in groundwater content, and should therefore be removed from the time-series.

Complete Two Loop Electroweak Contributions to the Muon Lifetime in the Standard Model

Publisher: name: arXiv
Year: 2003
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)
subject: FOS: Physical sciences

description: An independent result for the two loop fermionic contributions to the muon lifetime in the Standard Model is obtained. Deviations are found with respect to \cite{Freitas:2000gg}, which result in a shift of the W boson mass by approximately -1.3 MeV over the range of Higgs boson masses from 100 GeV to 1 TeV. Supplied with the bosonic contributions from \cite{Awramik:2002wn,Onishchenko:2002ve,Awramik:2002vu}, this shift, due to the complete electroweak contributions, varies from -2.4 MeV to -0.6 MeV. Additionally, a new test of the matching procedure defining the Fermi constant is presented, which uses fermion masses as infrared regulators.

description: An extensive analysis has been carried out of the performance of standard families of basis sets with the hierarchy of coupled cluster methods CC2, CCSD, CC3 and CCSDT in computing selected Oxygen, Carbon and Nitrogen K-edge (vertical) core excitation and ionization energies within a core-valence separated scheme in the molecules water, ammonia, and carbon monoxide. Complete basis set limits for the excitation energies have been estimated via different basis set extrapolation schemes. The importance of scalar relativistic effects has been established within the spin-free exact two-component theory in its one-electron variant (SFX2C-1e).

description: The gastrointestinal tract in the adult Drosophila serves as a model system for exploring the mechanisms underlying digestion, absorption and excretion, stem cell plasticity, and inter-organ communication, particularly through the gut–brain axis. It is also useful for studying the cellular and adaptive responses to dietary changes, alterations in microbiota and immunity, and systematic and endocrine signals. Despite the various cell types and distinct regions in the gastrointestinal tract, few tools are available to target and manipulate the activity of each cell type and region, and their gene expression. Here, we report 353 GAL4 lines and several split-GAL4 lines that are expressed in enteric neurons (ENs), progenitors (ISCs and EBs), enterocytes (ECs), enteroendocrine cells (EEs), or/and other cell types that are yet to be identified in distinct regions of the gut. We had initially collected approximately 600 GAL4 lines that may be expressed in the gut based on RNA sequencing data, and then crossed them to UAS-GFP to perform immunohistochemistry to identify those that are expressed selectively in the gut. The cell types and regional expression patterns that are associated with the entire set of GAL4 drivers and split-GAL4 combinations are annotated online at http://kdrc.kr/index.php (K-Gut Project). This GAL4 resource can be used to target specific populations of distinct cell types in the fly gut, and therefore, should permit a more precise investigation of gut cells that regulate important biological processes.

description: I've been building Powerpoint-based quantum computers with electron spins in silicon for 20 years. Unfortunately, real-life-based quantum dot quantum computers are harder to implement. Materials, fabrication, and control challenges still impede progress. The way to accelerate discovery is to make and measure more qubits. Here I discuss separating the qubit realization and testing circuitry from the materials science and on-chip fabrication that will ultimately be necessary. This approach should allow us, in the shorter term, to characterize wafers non-invasively for their qubit-relevant properties, to make small qubit systems on various different materials with little extra cost, and even to test spin-qubit to superconducting cavity entanglement protocols where the best possible cavity quality is preserved. Such a testbed can advance the materials science of semiconductor quantum information devices and enable small quantum computers. This article may also be useful as a light and light-hearted introduction to quantum dot spin qubits.

Chern-Simons Solitons, Chiral Model, and (affine) Toda Model on Noncommutative Space

Year: 2004
Subjects: subject: High Energy Physics - Theory (hep-th)

description: We consider the Dunne-Jackiw-Pi-Trugenberger model of a U(N) Chern-Simons gauge theory coupled to a nonrelativistic complex adjoint matter on noncommutative space. Soliton configurations of this model are related the solutions of the chiral model on noncommutative plane. A generalized Uhlenbeck's uniton method for the chiral model on noncommutative space provides explicit Chern-Simons solitons. Fundamental solitons in the U(1) gauge theory are shaped as rings of charge `n' and spin `n' where the Chern-Simons level `n' should be an integer upon quantization. Toda and Liouville models are generalized to noncommutative plane and the solutions are provided by the uniton method. We also define affine Toda and sine-Gordon models on noncommutative plane. Finally the first order moduli space dynamics of Chern-Simons solitons is shown to be trivial.

description: We report on measurements of charge transfer in GEM structures in high magnetic fields. These were performed in the framework of the R&D work for a Time Projection Chamber at a future Linear Collider. A small test chamber has been installed into the aperture of a superconducting magnet with the GEM structures mounted perpendicular to the B field direction. The charge transfer is derived from the electrical currents monitored during irradiation with an ${}^{55}$Fe source. No severe loss of primary ionisation charge is observed, but an improved ion feedback suppression is achieved for high magnetic fields. Additionally, the width of the charge cloud released by individual ${}^{55}$Fe photons is measured using a finely segmented strip readout after the triple GEM structure. Charge widths between 0.3 and 0.5 mm RMS are observed, which originate from the charge broadening inside the GEM readout. This charge broadening is only partly suppressed at high magnetic fields.

description: Using concepts developed in string theory, Cohen, Moore, Nelson and Polchinski calculated the propagator for a relativistic point particle. Following these authors we extend the technique to include the case of closed world lines. The partition function found corresponds to the Feynmann and Schwinger proper time formalism. We also explicitly verify that the partition function is equivalent to the usual path length action partition function. As an example of a sum over closed world lines, we compute the Euler-Heisenberg effective Lagrangian in a novel way.
