description: Efficiency has been proven to be an important managerial tool in improving total factor productivity in agriculture. The four sources of economic inefficiency: allocative, technical, pure technical and scale inefficiency of a sample of seventy-six Nepalese rice farmers were examined using the data envelopment analysis (DEA) decomposition method. The inefficiency indices computed by the DEA were then used as the dependent variable in a Tobit (censored) regression model using decision- makers’ attributes as the explanatory variables. The results revealed relatively large inefficiencies among the farms sampled. The average economic, allocative, technical, pure technical and scale inefficiencies were 34%, 13%, 24%, 18%, and 7% respectively. There is also a significant variation in the level of inefficiency across farms. The inefficiencies are attributed to the variations in use intensities of resources such as farm land, seed, human labour, fertilisers and mechanical power. The inefficiencies were explained by farmers’ level of age, education, gender, family labour endowment and risk aversion. Therefore, to be successful the efficiency improvement program must be flexible enough to accommodate the diversity of farmers and their improvement needs. The results also suggest that increasing effort towards educating farmers on best practices can enhance efficiency in Nepalese rice farming. Other policy implications and development strategies are also drawn from the findings.

description: Australian agriculture has suffered from a long-term decline in its terms of trade and a persistent cost-price squeeze. The effects on farm viability have led to declining and aging rural populations, rising rural unemployment, and substantial agricultural restructuring. To cushion these effects and assist in rural restructuring Australian State and Federal Governments have provided support to primary producers including drought aid, reconstruction aid and other support mechanisms. In Queensland the principle agency responsible for providing this support is the Queensland Rural Adjustment Authority (QRAA). This paper will examine the recent pattern of support QRAA has provided the Queensland beef industry and comment on its effectiveness and flow-on effects.

description: This paper suggests a new approach to econometrically estimate parameters of multi-level Constant Elasticity of Transformation (CET) functional forms which are widely used in developing Computable General Equilibrium (CGE) models. An illustrative CET functional form is estimated using the proposed method based on historical data taken from the U.S. economy for the time period of 1996-210 to evaluate the performance of the new method. The proposed estimation process may be used to improve the existing cropland frontier used in GTAP-BIO model. Currently, the cropland frontier in GTAP-BIO model supplies land to different crops using a simple one-level CET function due to the lack of empirically estimated more flexible functional forms. The proposed method provides an opportunity to estimate more flexible multi-level CET functional forms according to available historical data. This will help to change the land supply side of the GTAP-BIO model based on historical observations.

description: A many-body system of fermion atoms with a model interaction characterized by the scattering length $a$ is considered. We treat both $a$ and the density as parameters assuming that the system can be created artificially in a trap. If $a$ is negative the system becomes strongly correlated at densities $ρ\sim |a|^{-3}$, provided the scattering length is the dominant parameter of the problem. It means that we consider $|a|$ to be much bigger than the radius of the interaction or any other relevant parameter of the system. The density $ρ_{c1}$ at which the compressibility vanishes is defined by $ρ_{c1}\sim |a|^{-3}$. Thus, a system composed of fermion atoms with the scattering length $a\to -\infty$ is completely unstable at low densities, inevitably collapsing until the repulsive core stops the density growth. As a result, any Fermi system possesses the equilibrium density and energy if the bare particle-particle interaction is sufficiently strong to make $a$ negative and to be the dominant parameter. This behavior can be realized in a trap. Our results show that a low density neutron matter can have the equilibrium density.

description: This article studies a Bi-criteria Multiple-choice Secretary Problem (BMSP) with full information. A sequence of candidates arrive one at a time, with a two-dimensional attribute vector revealed upon arrival. A decision maker needs to select a total number of η candidates to fill η job openings, based on the attribute vectors of candidates. The objective of the decision maker is to maximize the expected sum of attribute values of selected candidates for both dimensions of the attribute vector. An approach for generating Pareto-optimal policies for BMSP is proposed using the weighted sum method. Moreover, closed-form expressions for values of both objective functions under Pareto-optimal policies for BMSP are provided to help a decision maker in the policy planning stage. These analysis techniques can be applied directly to solve the more general class of multi-criteria multiple-choice Secretary Problems, provided the objective functions are in the form of accumulating a product-form reward for each selected candidate.

description: This paper examines the short run sensitivity of willingness to pay (WTP) estimates for groundwater quality and quantity in the presence of external shocks, using data from two choice experiments implemented in Zagreb, Croatia. To assess the sensitivity of WTP estimates we take advantage of a sudden deterioration in political stability, expressed by a series of public protests that took place in the city during the data collection and compare mean WTP estimates before and during the protests. We find that mean WTP for groundwater quality and quantity is sensitive to the occurrence of the protest. The result indicates that events unrelated to environmental quality and especially political instability can influence the valuation of environmental goods. We interpret the result as an indication that the choice experiment method is sensitive enough to capture changes in WTP that are a result of sudden changes in the state of the world.

description: This study investigates the factors that impact the duration of trade relationships in U.S. fresh fruit and vegetable imports. We employ both the survival analysis (KM estimates and Cox PH model) as well as a count data model. The preliminary results indicate that SPS treatment requirements positively impact duration while new market access issued during the study period negatively impacts duration. Developed countries and countries located in North America experience longer duration. Other factors typically included in trade duration models were also investigated. Additionally, we employ a Heckman two-step procedure to understand the impact of duration on the probability of trading and trade volume, and find that both are positively impacted therefore suggesting that more stable trade relationships also tend to involve a higher volume of trade.

description: Demographic projections of future mortality rates involve a high level of uncertainty and require stochastic mortality models. The current paper investigates forward mortality models driven by a (possibly infinite dimensional) Wiener process and a compensated Poisson random measure. A major innovation of the paper is the introduction of a family of processes called forward mortality improvements which provide a flexible tool for a simple construction of stochastic forward mortality models. In practice, the notion of mortality improvements are a convenient device for the quantification of changes in mortality rates over time that enables, for example, the detection of cohort effects. We show that the forward mortality rates satisfy Heath-Jarrow-Morton-type consistency conditions which translate to the forward mortality improvements. While the consistency conditions of the forward mortality rates are analogous to the classical conditions in the context of bond markets, the conditions of the forward mortality improvements possess a different structure: forward mortality models include a cohort parameter besides the time horizon; these two dimensions are coupled in the dynamics of consistent models of forwards mortality improvements. In order to obtain a unified framework, we transform the systems of Itô-processes which describe the forward mortality rates and improvements: in contrast to term-structure models, the corresponding stochastic partial differential equations (SPDEs) describe the random dynamics of two-dimensional surfaces rather than curves.

description: Background: While the relations between sleep, cognition and behavior have been extensively studied in adolescents and school-aged children, very little attention has been given to preschoolers. Objective: In this systematic review, our aim was to survey articles that address the link between sleep and both cognition and behavior in preschoolers (24 to 72 months old). Methods: Four electronic databases were searched, namely Medline, Web of Science, PsycINFO and ERIC, completed by forward and backward citation search. Results: Among the 1590 articles identified (minus duplicates), 26 met the inclusion criteria. Globally, studies with the largest sample sizes (N=13) found that a greater quantity or quality of sleep was associated with better behavioral and cognitive outcomes, while the others were less consistent. Conclusion: Although the current literature seems to indicate that sleep is related to behavioral and cognitive development as early as preschool years, the strength of the associations (i.e. effect sizes) was relatively small. In addition to taking stock of the available data, this systematic review identifies potential sources of improvement for future research.

description: We develop a double mean-field theory for charged macrogels immersed in electrolyte solutions in the spirit of the cell model approach. We first demonstrate that the equilibrium sampling of a single explicit coarse-grained charged polymer in a cell yields accurate predictions of the swelling equilibrium if the geometry is suitably chosen and all pressure contributions have been incorporated accurately. We then replace the explicit flexible chain by a suitably modeled penetrable charged rod that allows to compute all pressure terms within the Poisson-Boltzmann approximation. This model, albeit computationally cheap, yields excellent predictions of swelling equilibria under varying chain length, polymer charge fraction, and external reservoir salt concentrations when compared to coarse-grained molecular dynamics simulations of charged macrogels. We present an extension of the model to the experimentally relevant cases of pH-sensitive gels.

description: Helobdella papillata (Verrill, 1872) Siddall and Borda, 2003   Figure 17
 The presence of one pair of eyespots, longitudinal dorsal pigmented stripes, and rows of black-tipped papillae as well as one annulus between gonopores and diffuse salivary glands match the description of Helobdella papillata. This species belongs to the “ triserialis ” complex of species defined by Sawyer, 1986. Helobdella triserialis (Blanchard, 1894) was originally described based on specimens collected in Chile. However, because of the high degree of variation in the various forms in the New World, Ringuelet (1943) lumped them all under “ H. triserialis. ” Siddall and Borda (2003) found that at least North and South American forms each constitute distinct evolutionary lineages and resurrected Verrill’s name, Helobdella papillata, for North American forms, all of which are genetically similar regardless of pigmentation. Specimens were found on the underside of submerged rocks and wood.

In this talk we describe an application of this breakthrough to improve our understanding of the background to the search for a light Higgs boson at the LHC. In particular, we focus on the QCD corrections to the gluon fusion subprocess gg to gamma gamma, which forms an important component of the background in the di-photon channel. We find that the K factor for this subprocess is significantly smaller than estimated previously.

description: The nature of the knee in the all-particle spectrum of cosmic rays remains subject of much investigation, especially in the aftermath of recent measurements claiming the detection of a knee-like feature in the spectrum of the light component of cosmic rays at energy $\sim$700 TeV, at odds with the standard picture in which the knee in the all-particle spectrum is dominated by light cosmic rays. Here we investigate the implications of this and other scenarios in terms of the measured flux of atmospheric neutrinos. In particular we discuss the possibility that the spectrum of atmospheric neutrinos in the region $\gtrsim$50 TeV may provide information about the different models for the mass composition in the knee region. We investigate the dependence of the predicted atmospheric neutrino flux on the shape of the light cosmic ray spectra and on the interaction models describing the development of showers in the atmosphere. The implications of all these factors for the identification of the onset of an astrophysical neutrino component are discussed.

description: We compute the expectations of the squares of the electric and magnetic fields in the vacuum region outside a half-space filled with a uniform dispersive dielectric. We find a positive energy density of the electromagnetic field which diverges at the interface despite the inclusion of dispersion in the calculation. We also investigate the mean squared fields and the energy density in the vacuum region between two parallel half-spaces. Of particular interest is the sign of the energy density. We find that the energy density is described by two terms: a negative position independent (Casimir) term, and a positive position dependent term with a minimum value at the center of the vacuum region. We argue that in some cases, including physically realizable ones, the negative term can dominate in a given region between the two half-spaces, so the overall energy density can be negative in this region.

It is shown that the Hawking radiation of Dirac particles does not exist for $P_1, Q_2$ components, but for $P_2, Q_1$ components it does. Both the location and the temperature of the event horizon change with time. The thermal radiation spectrum of Dirac particles is the same as that of Klein-Gordon particles.

Mechanism of unconventional superconductivity induced by skyrmion excitations in two-dimensional strongly-correlated electron systems

Year: 2001
Subjects: subject: Strongly Correlated Electrons (cond-mat.str-el)

description: We propose a mechanism of unconventional superconductivity in two-dimensional strongly-correlated electron systems. We consider a two-dimensional Kondo lattice system or double-exchange system with spin-orbit coupling arising from buckling of the plane. We show that a Chern-Simons term is induced for a gauge field describing the phase fluctuations of the localized spins. Through the induced Chern-Simons term, carriers behave like skyrmion excitations that lead to a destruction mechanism of magnetic long-range order by carrier doping. After magnetic long-range order is destroyed by carrier doping, the Chern-Simons term plays a dominant role and the attractive interaction between skyrmions leads to unconventional superconductivity. For the case of the ferromagnetic interaction between the localized spins, the symmetry of the Cooper pair is p-wave ($p_x \pm ip_y$). For the case of the antiferromagnetic interaction between the localized spins, the symmetry of the Cooper pair is d-wave ($d_{x^2-y^2}$). Applications to various systems are discussed, in particular to the high-$T_c$ cuprates.

Impact of the mineralogical composition of natural pozzolan on properties of resultant geopolymers

Subjects: Biophysics

description: This article presents a comparison between the impact of different mineralogical compositions of natural pozzolans for geopolymer synthesis. Beyond an optimum silica modulus, the compressive strength either increases on low rate or decreases with age. The presence of zeolite minerals enhances the reactivity of natural pozzolans. In contrast, the presence of calcite can lead to the incorporation of calcium into the reaction products. At the same time, the carbonate can enhance the formation of sodium carbonate, which can deplete the alkalis and water from binder gel, thereby reducing the rate of compressive strength development. In severe cases, the crystallization pressure of sodium carbonate can cause a complete disintegration of the structure. These effects are pronounced for samples outside the optimum silica modulus range and for low reactive pozzolans.

description: The contactless selective manipulation of individual objects at the microscale is powerfully enabled by acoustical tweezers based on acoustical vortices [Baudoin et al., Sci. Adv., 5:eaav1967 (2019)]. Nevertheless, the ability to assemble multiple objects with these tweezers has not yet been demonstrated yet and is critical for many applications, such as tissue engineering or microrobotics. To achieve this goal, it is necessary to overcome a major difficulty: the ring of high intensity ensuring particles trapping at the core of the vortex beam is repulsive for particles located outside the trap. This prevents the assembly of multiple objects. In this paper, we show (in the Rayleigh limit and in 2D) that this problem can be overcome by trapping the target objects at the core of two synchronized vortices. Indeed, in this case, the destructive interference between neighboring vortices enables to create an attractive path between the captured objects. The present work may pioneer particles precise assembly and patterning with multi-tweezers.

description: A new class of solutions of the Einstein field equations in spherical symmetry is found. The new solutions are mathematically described as the metrics admitting separation of variables in area-radius coordinates. Physically, they describe the gravitational collapse of a class of anisotropic elastic materials. Standard requirements of physical acceptability are satisfied, in particular, existence of an equation of state in closed form, weak energy condition, and existence of a regular Cauchy surface at which the collapse begins. The matter properties are generic in the sense that both the radial and the tangential stresses are non vanishing, and the kinematical properties are generic as well, since shear, expansion, and acceleration are also non-vanishing. As a test-bed for cosmic censorship, the nature of the future singularity forming at the center is analyzed as an existence problem for o.d.e. at a singular point using techniques based on comparison theorems, and the spectrum of endstates - blackholes or naked singularities - is found in full generality.

description: The galaxy bispectrum contains a wealth of information about the early universe, gravity, as well as astrophysics such as galaxy bias. In this paper, we study the parity-odd part of the galaxy bispectrum which is hitherto unexplored. In the standard cosmological model, the odd-parity bispectrum is generated by galaxy velocities through redshift-space distortions. While small in the case of General Relativity coupled with smooth dark energy, the signal could be larger in modified gravity scenarios. Thus, apart from being a very useful consistency test of measurements of galaxy clustering, the odd bispectrum offers a novel avenue for searching for new physics.

description: Fiber-optical networks are a crucial telecommunication infrastructure in society. Wavelength division multiplexing allows for transmitting parallel data streams over the fiber bandwidth, and coherent detection enables the use of sophisticated modulation formats and electronic compensation of signal impairments. In the future, optical frequency combs may replace multiple lasers used for the different wavelength channels. We demonstrate two novel signal processing schemes that take advantage of the broadband phase coherence of optical frequency combs. This approach allows for a more efficient estimation and compensation of optical phase noise in coherent communication systems, which can significantly simplify the signal processing or increase the transmission performance. With further advances in space division multiplexing and chip-scale frequency comb sources, these findings pave the way for compact energy-efficient optical transceivers.

description: Many farmers in West Timor operate small-scale mixed crop-livestock farms. In most of these farms, productivity of livestock production systems is quite low. There is, however, a potential to improve the contribution of livestock to total household income. Combining breeding and fattening represents an alternative for improving livestock production systems. To examine the feasibility of this production system, a study was conducted in three districts in West Timor. A model of small ruminant production systems was constructed. The production model included economics as well as biological parameters such as age of sexual maturity, age at first mating and age at first kidding. Results of the study indicated that both enterprises would yield positive returns. The financial indicators all showed favourable return from these investments.

description: A systematic study of hole compensation effect on magnetic properties, which is controlled by defect compensation through ion irradiation, in (Ga,Mn)As, (In,Mn)As and (Ga,Mn)P is presented in this work. In all materials, both Curie temperature and magnetization decrease upon increasing the hole compensation, confirming the description of hole mediated ferromagnetism according to the p-d Zener model. The material dependence of Curie temperature and magnetization versus hole compensation reveals that the manipulation of magnetic properties in III-Mn-V dilute ferromagnetic semiconductors by ion irradiation is strongly influenced by the energy level location of the produced defect relative to the band edges in semiconductors.

description: We have considered the structure of the fundamental symmetry violating part of the photon refractive index in vacuum in the presence of constant electric and magnetic fields. This part of the refractive index can, in principle, contain CPT symmetry breaking terms. Some of the terms violate Lorentz invariance, whereas the others violate locality and causality. Estimates of these effects, using laser experiments are considered.

description: Erpobdella punctata (Leidy, 1870)   Figure 22
 Erpobdella punctata is widely distributed in North America with highly variable pigmentation patterns (see diagrams in Klemm, 1982; Madill and Hovingh, 2007). The presence of two longitudinal paramedial stripes on the dorsal surface, as well as three pairs of eyespots, two annuli between gonopores and ejaculatory ducts not forming preatrial loops are consistent with the characteristics of E. punctata. Found on the underside of submerged rocks and wood.

description: The effects of plasticization of poly(methyl methacrylate) glass on the boson peaks observed by Raman and neutron scattering are compared. In plasticized glass the cohesion heterogeneities are responsible for the neutron boson peak and partially for the Raman one, which is enhanced by the composition heterogeneities. Because the composition heterogeneities have a size similar to that of the cohesion ones and form quasiperiodic clusters, as observed by small angle X-ray scattering, it is inferred that the cohesion heterogeneities in a normal glass form nearly periodic arrangements too. Such structure at the nanometric scale explains the linear dispersion of the vibrational frequency versus the transfer momentum observed by inelastic X-ray scattering.
