description: We review the constraints given by the linear matter power spectra data on cosmological and bias parameters, comparing the data from the PSCz survey (Hamilton et al., 2000) and from the matter power spectrum infered by the study of Lyman alpha spectra at z=2.72 (Croft et al., 2000). We consider flat--$Λ$ cosmologies, allowing $Λ$, $H_0$ and $n$ to vary, and we also let the two ratio factors $r_{pscz}$ and $r_{lyman}$ ($r^2_i = \frac{P_{i}(k)}{P_{CMB}(k)}$) vary independently. Using a simple $χ^2$ minimisation technique, we find confidence intervals on our parameters for each dataset and for a combined analysis. Letting the 5 parameters vary freely gives almost no constraints on cosmology, but requirement of a universal ratio for both datasets implies unacceptably low values of $H_0$ and $Λ$. Adding some reasonable priors on the cosmological parameters demonstrates that the power derived by the PSCz survey is higher by a factor $\sim 1.75$ compared to the power from the Lyman $α$ forest survey.

description: Demand for pesticides, inorganic and organic fertilizers were jointly estimated using survey data from a randomly selected 81 BRAC `contract hybrid vegetables and cereal seed growers' in northwestern Bangladesh applying a simultaneous equation framework. Pesticide cost accounts for 6.9% of the gross value of output in hybrid seeds of vegetables and 3.2% in cereals. About 87% of farmers used pesticides at least once with mean number of application of 4.4 times. Twenty-seven brands of pesticides were used including a substantial number of banned pesticides. Price elasticity of demand for pesticides, fertilizers and biofertilizers were estimated at -0.83, -0.21 and -1.13, respectively. Farmers treat chemical fertilizers and pesticides as complements. Increase in prices of both vegetable and cereal seeds significantly increases pesticide demand. Farmers who use mask as a precaution during pesticide application apply significantly higher amount of all three inputs. Farmers' level of education and experience significantly reduce pesticide use. Major thrust for pesticides regulation and effective implementation, promotion of education and increasing farmers' awareness on effects of pesticide use were suggested to safeguard the farmers.

description: The key concern of this research is to assess the growth, fluctuation and price flexibility of Aus, Aman, Boro, wheat and jute crops during the last two decades of the twentieth century. Real prices of all the crops have been falling significantly during the study period. The price instability was higher than area and yield instability for all these crops studied. The extent of real price fluctuations was higher relative to area, production and yield fluctuation of all the crops. It was observed that supply of Aus, wheat and jute production played insignificant role to determine their own post-harvest prices, but Boro, Aman and Aus production had significant role on the prices of crops of Aus, wheat and jute through significant cross effects. On the other hand, Aman and Boro production had significant influence on post-harvest price determination of these rice varieties as revealed by price flexibility co-efficients. So price policy measures cannot be taken on a single crop basis in Bangladesh.

description: We present results of a high-statistics study of scalar and pseudoscalar meson propagators in quenched QCD at two values of lattice spacing, beta = 5.7 and 5.9, with clover-improved Wilson fermions. The study of the chiral limit is facilitated by the pole-shifting ansatz of the modified quenched approximation. Pseudoscalar masses and decay constants are determined as a function of quark mass and quenched chiral log effects are estimated. A study of the flavor singlet eta prime hairpin diagram yields a precise determination of the eta prime mass insertion. The corresponding value of the quenched chiral log parameter delta is compared with the observed QCL effects. Removal of QCL effects from the scalar propagator allows a determination of the mass of the lowest lying isovector scalar $q\bar{q}$ meson.

description: The paper evaluates the agricultural incentives in terms of levels of protection of selected agricultural commodities in Bangladesh for the period 1980-1998. Secondary data from various official and private sources were collected and compiled to derive the necessary parameters and co-efficients used in the analysis. NPC and NRP were measured by the proportional difference between the domestic producer price and the border price (adjusting for distribution, transportation, and other marketing costs). Likewise EPC and ERP were measured by considering the value-added components for fuller protection representation of incentive. The results showed that the main cereal crop rice was marginally protected for the policy goal of self-sufficiency. Wheat, jute, and potato were negatively protected during the period under review. But sugar production was highly protected due to inefficiency in publicly managed enterprise.

description: Although linear regression models are fundamental tools in statistical science, the estimation results can be sensitive to outliers. While several robust methods have been proposed in frequentist frameworks, statistical inference is not necessarily straightforward. We here propose a Bayesian approach to robust inference on linear regression models using synthetic posterior distributions based on $γ$-divergence, which enables us to naturally assess the uncertainty of the estimation through the posterior distribution. We also consider the use of shrinkage priors for the regression coefficients to carry out robust Bayesian variable selection and estimation simultaneously. We develop an efficient posterior computation algorithm by adopting the Bayesian bootstrap within Gibbs sampling. The performance of the proposed method is illustrated through simulation studies and applications to famous datasets.

description: Vocal fold (VF) motion is a fundamental process in voice production, and is also a challenging problem for direct numerical computation because the VF dynamics depend on nonlinear coupling of air flow with the response of elastic channels (VF), which undergo opening and closing, and induce internal flow separation. A traditional modeling approach makes use of steady flow approximation or Bernoulli's law which is known to be invalid during VF opening. We present a new hydrodynamic semi-continuum system for VF motion. The airflow is modeled by a quasi-one dimensional continuum aerodynamic system, and the VF by a classical lumped two mass system. The reduced flow system contains the Bernoulli's law as a special case, and is derivable from the two dimensional compressible Navier-Stokes equations. Since we do not make steady flow approximation, we are able to capture transients and rapid changes of solutions, e.g. the double pressure peaks at opening and closing stages of VF motion consistent with experimental data. We demonstrate numerically that our system is robust, and models in-vivo VF oscillation more physically. It is also much simpler than a full two-dimensional Navier-Stokes system.

description: We study multiphoton blockade and photon-induced tunneling effects in the two-photon Jaynes-Cummings model, where a single-mode cavity field and a two-level atom are coupled via a two-photon interaction. We consider both the cavity-field-driving and atom-driving cases, and find that single-photon blockade and photon-induced tunneling effects can be observed when the cavity mode is driven, while the two-photon blockade effect appears when the atom is driven. For the atom-driving case (the two-photon transition process), we present a criterion of the correlation functions for the multiphoton blockade effect. Specifically, we show that quantum interference can enhance the photon blockade effect in the single-photon cavity-field-driving case. Our results are confirmed by analytically and numerically calculating the correlation function of the cavity-field mode. Our work has potential applications in quantum information processing and paves the way for the study of multiphoton quantum coherent devices.

description: A first theoretical study for neutrino-induced diffractive productions of heavy pseudoscalar-mesons, η_c and η_b, off a nucleon is performed based on factorization formalism in QCD. We evaluate the forward diffractive production cross section in perturbative QCD in terms of the light-cone wave functions of Z boson and η_{c,b} mesons, and the gluon distribution of the nucleon. The diffractive production of η_c is governed by the axial vector coupling of the longitudinally polarized Z boson to Q\bar{Q} pair, and the resulting η_c production cross section is larger than the J/ψone by one order of magnitude. The bottomonium η_b production, which shows up for higher beam energy, is also discussed.

We prove the Gaussian estimates for the kernel of $e^{-tL}$, as well as that of $\partial_t^le^{-tL}$, for any $l\in\mathbb{N}$. We show that the square root of $L$ satisfies the $L^p$ estimates $\left\Vert{L^{1/2}f}\right\Vert_{L^p}\lesssim\left\Vert{\nabla f}\right\Vert_{L^p}$ for $10$ depending on the ellipticity constant and the BMO semi-norm of the coefficients. Finally, we prove the $L^p$ estimates for square functions associated to $e^{-tL}$. In another article of the authors, these results are used to establish the solvability of the Dirichlet problem for elliptic equation ${\rm div}(A(x)\nabla u)=0$ in the upper half-space $(x,t)\in\mathbb{R}_+^{n+1}$ with the boundary data in $L^p(\mathbb{R}^n,dx)$ for some $p\in (1,\infty)$.

description: Although experimental evidence for the correlation between early flame kernel development and cycle-to-cycle variations (CCV) in spark ignition (SI) engines was provided long ago, there is still a lack of fundamental understanding of early flame/turbulence interactions, and accurate models for full engine simulations do not exist. Since the flame kernel is initiated with small size, i.e. with large positive curvature, differential diffusion is expected to severely alter early flame growth in non-unity-Lewis-number (${\mathrm{Le}\neq1}$) mixtures as typically used in engines. In this work, a DNS database of developing iso-octane/air flame kernels and planar flames has been established with flame conditions representative for stoichiometric engine part-load operation. Differential diffusion effects on the global heat release rate are analyzed by relating the present findings to equivalent flames computed in the ${\mathrm{Le}=1}$ limit. It is shown that in the early kernel development phase, the normal propagation velocity is significantly reduced with detrimental consequences on the global burning rate of the flame kernel. Besides this impact on the overall mass burning rate, the initial production of flame surface area by the normal propagation term in the flame area balance equation is noticeably reduced. By using the optimal estimator concept, it is shown that strong fluctuations in local heat release rate inherent to ${\mathrm{Le}\neq1}$ flames in the thin reaction zones regime are mainly contained in the parameters local equivalence ratio, enthalpy, and H-radical mass fraction. Differential diffusion couples the evolution of these parameters to the unsteady flame geometry and structure, which is analyzed in Part II of the present study (Falkenstein et al., Combust. Flame, 2019).

description: ABSTRACT Groundnut is the principal vegetable oil crop in India and occupies the top slot in terms of area as well as production of total oilseeds in the country. However, about 85 percent area under groundnut remains rainfed of which nearly 80 percent comes under dryland where irrigation facilities do not exist at all. There has been gradual increase in the productivity of this crop over the last three decades. However, the enhancement was particularly spectacular in better environments. In harsh environment, not only the yields are low but also it fluctuates violently. Introduction of exotic varieties could not mitigate this problem; rather increased the problem of insect pests and disease pathogens in rainfed groundnut. Concerns are also being raised on the very profitability and sustainability issues of this oilseed crop under free economy hypotheses. On the other hand, if yield gap statistics are any indication then there exists a large potential to raise productivity of this crop. Keeping these issues in mind efforts have been made in this study to identify and prioritize production constraints in rainfed groundnut production system and to explore major researchable issues.

description: This article quantifies the impact of H7N9 bird flu on chicken demand and consumer willingness to pay (WTP) in China. The surveys were administered to the same group of respondents in April 2012 and 2013. In 2012 we asked generic questions regarding food safety in chilled chicken without any mentioning of bird flu and in 2013 in the midst of the outbreak we resurveyed the group again. Since these respondents were surveyed both times (before and after the bird flu outbreak), the data formed a “natural experiment”. We measure risk perception, fear and trust against actual reduction in consumption and stated change in WTP for safe chicken between 2012 and 2013. Through a survey conducted in each year on the same Chinese urban consumers, we are able to construct a Marshallian-Hicksian elasticity measure signifying the relative welfare loss from a food risk. Furthermore, we found that: (1) like fear, the impact of distrust (especially the distrust in government) was negative for consumption; (2) macro fear of H7N9’s spreading, and distrust in government enhanced the deviation of consumption and WTP; (3) stronger consumer heterogeneity in consumption existed in cities with higher number of incidences; (4) the sheer mentioning of H7N9 is more important and negative than whether it was associated with a risk-perception reducing or risk-perception elevating message given to consumers; and (5) unlike what the conventional theory would predict that upon the rising of a specific risk factor, demand will drop and WTP for safter products will increase, while consumption of chicken never increased after the emergence of H7N9 in 2013, WTP for safer chicken did not increase either relative to generic risks associated with consuming chicken in 2012.

We derive a new, precise X-ray position for the source and determine its spin period, P=6.978977(24) s. Time resolved X-ray spectra show no significant variation as a function of pulse phase. We have detected excess emission beyond 4 arcsec from the central source extending to beyond 100 arcsec, due to the supernova remnant and possibly dust scattering from the interstellar medium.

TECHNOLOGICAL CHANGE AND FOOD PRODUCTION SUSTAINABILITY IN BANGLADESH AGRICULTURE

Subjects: Production Economics

description: Although `Green Revolution' technology is the major technological breakthrough in agricultural history, which is adopted by nations worldwide, including Bangladesh, to boost their foodgrain production, it is increasingly felt that productivity from this new agricultural technology is declining and is a threat to sustainability of economic development. The present study attempted to evaluate the role of technological change in augmenting aggregate crop growth and sustaining food production for the future in Bangladesh. The overall hypothesis is that, though modem technology diffusion has contributed to crop production increase, it has not spread uniformly across regions and the long-run crop production is reaching a saturation level, thereby, threatening food production sustainability. Database of the study consists of time-series data for 47 years (1948 - 1994) and regionwise (19 region) data for 29 years (1961 - 1992). Results revealed that technological change played a significant role in augmenting aggregate crop productivity. `Constant return to scale' prevails in the crop sector when only traditional inputs are used while incorporation of technological and infrastructural factors revealed `increasing returns to scale'. But, declining productivity of modem rice, the major vehicle of technological change, is raising doubts on sustaining food production. The current increase in food production is largely due to switching from local to modem rice varieties and may not be sustainable in the long run. Trend analyses of 47 years of foodgrain production revealed that productivity is reaching a saturation value of 2,200 kg/ha, raising further doubts on food production sustainability to meet the growing demand. A policy of crop diversification incorporating non-foodgrain crops (potatoes, vegetables, spices, and cotton) as a strategy to sustain agricultural growth is suggested. Also, effective price policy, crop insurance policies, transportation, marketing, storage, extension and rural infrastructure development is suggested.

description: The rice production of Bangladesh has been investigated using a Cobb-Douglas stochastic production function which incorporates a model for the technical inefficiency effects. Farm level primary data collected by stratified random sampling technique are used for this study. The factors identified in the stochastic production frontiers which are responsible for the increase of production are extension service, farm size, bullock power, age and experience. Seed, fertilizer, human labour and irrigation cost were identified as important factors for the increase of production for only Boro rice and were not important factors for Aus and Aman rice crops. The models for the technical inefficiency effects in the Cobb-Douglas stochastic production frontiers include the farm-specific factors age, education, experience, extension contact and farm size. The factors which influence the technical inefficiency effects are identified by simultaneous estimations of stochastic production frontiers and technical inefficiency effect models for different rice crops. The study reveals that the impacts of age,, experience, extension contact and farm size on the technical inefficiency effects are significantly negative which means that technical inefficiency effects decrease significantly with the increase in the magnitudes of these factors. The study also indicates that there are significant technical inefficiency effects in the production of all rice crops and the random component of the inefficiency effects explains that a significant portion of the difference between the observed output and the maximum production frontier output is caused by differences in farmers' levels of technical efficiency.

description: The interaction of polymers with small-scale velocity gradients can trigger a coil-stretch transition in the polymers. We analyze this transition within a direct numerical simulation of shear turbulence with an Oldroyd-B model for the polymer. In the coiled state the lengths of polymers are distributed algebraically with an exponent alpha=2 gamma-1/De, where gamma is a characteristic stretching rate of the flow and De the Deborah number. In the stretched state we demonstrate that the length distribution of the polymers is limited by the feedback to the flow.
Towards Resolving the Crab $σ-$Problem: A Linear Accelerator?

description: Using the exact solution of the axisymmetric pulsar magnetosphere derived in a previous publication and the conservation laws of the associated MHD flow, we show that the Lorentz factor of the outflowing plasma increases linearly with distance from the light cylinder. Therefore, the ratio of the Poynting to particle energy flux, generically referred to as $σ$, decreases inversely proportional to distance, from a large value (typically $\gsim 10^4$)near the light cylinder to $\s \simeq 1$ at a transistion distance $R_{\rm trans}$. Beyond this distance the inertial effects of the outflowing plasma become important and the magnetic field geometry must deviate from the almost monopolar form it attains between $R_{lc}$ and $R_{\rm trans}$. We anticipate that this is achieved by collimation of the poloidal field lines toward the rotation axis, ensuring that the magnetic field pressure in the equatorial region will fall-off faster than $1/R^2$ ($R$ being the cylindrical radius). This leads both to a value $\s=ß\ll 1$ at the nebular reverse shock at distance $R_s$ ($R_s \gg R_{\rm trans}$) and to a component of the flow perpendicular to the equatorial component, as required by observation. The presence of the strong shock at $R = R_s$ allows for the efficient conversion of kinetic energy into radiation. We speculate that the Crab pulsar is unique in requiring $ß\simeq 3 \times 10^{-3}$ because of its small translational velocity, which allowed for the shock distance $R_s$ to grow to values $\gg R_{\rm trans}$.

description: We present the results of an extensive non-perturbative calculation of the renormalization constants of bilinear quark operators for the non-perturbatively O(a)-improved Wilson action. The results are obtained at four values of the lattice coupling, by using the RI/MOM and the Ward identities methods. A new non-perturbative renormalization technique, which is based on the study of the lattice correlation functions at short distance in x-space, is also numerically investigated. We then use our non-perturbative determination of the quark mass renormalization constants to compute the values of the strange and the average up/down quark masses. After performing an extrapolation to the continuum limit, we obtain ms^msbar(2 GeV) = (106 +- 2 +- 8) MeV and ml^msbar(2 GeV)=(4.4 +- 0.1 +- 0.4) MeV.

description: Knowledge about the regional disparities in the development of different sectors is an issue of considerable importance for administrators, planners and policy makers of any country. In this study an attempt has been made to evaluate the regional disparities in the development of the agricultural sector of Bangladesh through computing composite indices and relevant statistics for different districts based on secondary data. It is observed that out of 21 former districts of Bangladesh, the district of Chittagong ranked the first and the district Bandarban ranked the last in agricultural development during 1980-81 while Sylhet ranked first and Bandarban continued to occupy the last position during 1990-91. It is also observed that the level of development in 10 districts, out of 21 districts moved down during 1980-91. Significant change in development has also been observed over the two time periods.

description: We investigate the properties of localized waves in systems governed by nonlocal nonlinear Schrodinger type equations. We prove rigorously by bounding the Hamiltonian that nonlocality of the nonlinearity prevents collapse in, e.g., Bose-Einstein condensates and optical Kerr media in all physical dimensions. The nonlocal nonlinear response must be symmetric, but can be of completely arbitrary shape. We use variational techniques to find the soliton solutions and illustrate the stabilizing effect of nonlocality.

description: This study uses stochastic Cobb-Douglas production frontier to estimate farm level technical efficiency of rice farms. Average technical efficiency of sampled farms was estimated to be 85 percent with a minimum of 57 percent and a maximum of 96 percent. The results further showed that the visits of agricultural extension agents on the farm or farmers' visits to extension office and the availability of agricultural credit played significant role in improving technical efficiency. More experienced (aged) and educated farmers also realized high productive efficiency and thus output; however, the effect was not statistically significant. These results imply that considerable scope exists in the sampled area to increase rice output by improving farm management and providing other facilities to the farmers.

description: We formulate a new power-counting scheme for a chiral effective field theory of nucleons, pions, and Deltas. This extends chiral perturbation theory into the Delta-resonance region. We calculate nucleon Compton scattering up to next-to-leading order in this theory. The resultant description of existing $γ$p cross section data is very good for photon energies up to about 300 MeV. We also find reasonable numbers for the spin-independent polarizabilities $α_p$ and $β_p$.

description: One major component of the VO will be catalogs measuring gigabytes and terrabytes if not more. Some mechanism like XML will be used for structuring the information. However, such mechanisms are not good for information retrieval on their own. For retrieval we use queries. Topic Maps that have started becoming popular recently are excellent for segregating information that results from a query. A Topic Map is a structured network of hyperlinks above an information pool. Different Topic Maps can form different layers above the same information pool and provide us with different views of it. This facilitates in being able to ask exact questions, aiding us in looking for gold needles in the proverbial haystack. Here we discuss the specifics of what Topic Maps are and how they can be implemented within the VO framework. URL: http://www.astro.caltech.edu/~aam/science/topicmaps/

description: We generate a pair of entangled beams from the interference of two amplitude squeezed beams. The entanglement is quantified in terms of EPR-paradox [Reid88] and inseparability [Duan00] criteria, with observed results of $Δ^{2} X_{x|y}^{+} Δ^{2} X_{x|y}^{-} = 0.58 \pm 0.02$ and $\sqrt{Δ^{2} X_{x \pm y}^{+} Δ^{2} X_{x \pm y}^{-}} = 0.44 \pm 0.01$, respectively. Both results clearly beat the standard quantum limit of unity. We experimentally analyze the effect of decoherence on each criterion and demonstrate qualitative differences. We also characterize the number of required and excess photons present in the entangled beams and provide contour plots of the efficacy of quantum information protocols in terms of these variables.

Applying the theory of Hermitian and positive semidefinite matrices we prove two results that give simple bounds on coupling strengths which ensure the stability of synchronized chaos. Previous results in this area involving particular coupling schemes (e.g. global coupling and nearest neighbor diffusive coupling) are included as special cases of the present work.

description: This paper reports an experimental demonstration of moiré metalens which shows wide focal length tunability from negative to positive by mutual angle rotation at the wavelength of 900 nm. The moiré metalens was developed using high index contrast transmitarray meta-atoms made of amorphous silicon octagonal pillars, which is designed to have polarization insensitivity and full 2$π$ phase coverage. The fabricated moiré metalens showed focal length tunability at the ranges between $\pm$1.73 -- $\pm$5 mm, which corresponds to the optical power ranges between $\pm$578 -- $\pm$200 m$^{-1}$ at the mutual rotation between $\pm$90 degrees.
