description: We present the calculation of the $K_{l3}$ form factors with $N_f = 2 + 1$ nonperturbatively $O(a)$-improved Wilson quark action and Iwasaki gauge action at the physical point on a large volume of (10.9 fm)$^3$ at one lattice spacing of $a = 0.085$ fm. We extract the form factors from 3-point functions with three different time separations between the source and sink operators to confirm suppression of excited state contributions. The form factors are calculated in very close to the zero momentum transfer, $q^2 = 0$, thanks to the large volume, so that stable interpolations to $q^2 = 0$ are carried out. Using our form factors, we obtain the form factor at $q^2 = 0$, $f_+(0) = 0.9603(16)(^{+14}_{\ -4})(44)(19)(1)$, where the first, second, and fifth errors are statistical, systematic errors from fit functions and the isospin breaking effect, respectively. The third and fourth errors denote the finite lattice spacing effects estimated from the renormalization factor and contribution beyond the leading order SU(3) chiral perturbation theory (ChPT). The result of $f_+(0)$ yields the Cabibbo-Kobayashi-Maskawa (CKM) matrix element, $|V_{us}| = 0.2255(13)(4)$, where the first error comes from our calculation and the second from the experiment. This value is consistent with the ones determined from the unitarity of the CKM matrix and the $K_{l2}$ decay within one standard deviation, while it is slightly larger than recent lattice calculations by at most 1.5 $σ$. Furthermore, we evaluate the shape of the form factors and the phase space integral from our results. We confirm that those results are consistent with the experiment, and also $|V_{us}|$ determined with our phase space integral agrees with the one in the above.

Paradox of Modeling Curved Faults Revisited with General Non-Hypersingular Stress Green's Functions

description: In a dislocation problem, a paradoxical discordance is known to occur between an original smooth curve and an infinitesimally discretized curve. To solve this paradox, we have investigated a non-hypersingular expression for the integral kernel (called the stress Green's function) which describes the stress field caused by the displacement discontinuity. We first develop a compact alternative expression of the non-hypersingular stress Green's function for general two- and three-dimensional infinite homogeneous elastic media. We next compute the stress Green's functions on a curved fault and revisit the paradox. We find that previously obtained non-hypersingular stress Green's functions are incorrect for curved faults, and that smooth and infinitesimally segmented faults are equivalent. Their compatibility bridges the gap between analytical methods featuring curved faults and numerical methods using subdivided flat patches.

description: In this paper we developed and tested an integrated methodology for assessing direct and indirect economic impacts of flooding. The methodology combines a spatial analysis of damage to physical stocks with a general economic equilibrium approach using a regionally-calibrated (to Italy) version of a Computable General Equilibrium (CGE) global model. We applied the model to the 2000 Po river flood. To account for the uncertainty in the induced effects on regional economies, we explored three disruption and two recovery scenarios. The results prove that: i) indirect losses are a significant share of direct losses, and ii) the model is able to capture both positive and negative economic effects of a disaster in different areas of the same country. The assessment of indirect impacts is essential for a full understanding of the economic outcomes of natural disasters.

description: This study explored the caregiving experiences and expectations of mothers of children with disabilities. Eighteen mothers agreed to participate and share their caregiving experiences and expectations through a semi-structured interview. Using thematic data analysis, three main themes emerged: transformation of a mother, expectations regarding own needs, and expectations regarding child’s needs. Findings indicated that mothers required support due to the loss of their role, changes in lifestyle, the impact on family structure, and shortened routines. Mothers reported needing support for their mental and physical health, as well as help with sleep problems. They also expressed a desire to learn how to improve their children’s social skills, body structure and function, and independence. The findings highlight the importance of occupational therapists using appropriate approaches based on the mothers’ experiences and expectations to improve caregiving.

description: The mixing of active neutrinos with their sterile counterparts with keV mass is known to have a potentially major impact on the energy loss from the supernova core. By relying on a set of three static hydrodynamical backgrounds mimicking the early accretion phase and the Kelvin-Helmoltz cooling phase of a supernova, we develop the first self-consistent, radial- and time-dependent treatment of sterile and tau neutrinos mixing in the dense stellar core. We follow the flavor evolution by including ordinary matter effects, collisional production of sterile neutrinos, as well as reconversions of sterile states into active ones. The dynamical feedback of the sterile neutrino production on the matter background leads to the development of a tau lepton asymmetry that grows in time until it reaches a value larger than 0.15. Our results hint towards significant implications for the supernova physics, and call for a self-consistent modeling of the sterile neutrino transport in the supernova core to constrain the mixing parameters of sterile neutrinos.

description: We address the design and synthesis of optimal control strategies for high-dimensional stochastic dynamical systems. Such systems may be deterministic nonlinear systems evolving from random initial states, or systems driven by random parameters or processes. The objective is to provide a validated new computational capability for optimal control which will be achieved more efficiently than current state-of-the-art methods. The new framework utilizes direct single or multi-shooting discretization, and is based on efficient vectorized gradient computation with adaptable memory management. The algorithm is demonstrated to be scalable to high-dimensional nonlinear control systems with random initial condition and unknown parameters.

description: A dynamic model of transfrontier pollution is constructed to analyze production and residual emission decisions for two countries under cooperative and noncooperative behavior. Each country must allocate marginal resources between more commodity production or more residual (emission) reduction. while each country produces a different commodity (say, nickel and electricity), the jointly-produced residual (say, sulfur oxide) is identical. After emission and transport, the residuals are subject to deposition and possible accumulation in both countries. Cooperative and noncooperative behavior may lead to steady state equilibria. A comparison of the equations defining such equilibria permits the identification of corrective taxes, which depend not only on marginal damage but on the rates of transport, degredation and discount as well. While the cooperative solution is Pareto superior to the noncooperative solution, the necessary corrective taxes may not be adopted without side payments between countries. Movement toward the cooperative solution might be facilitated by an international control agency with the authority to impose emission standards on sources of transfrontier pollution. It is unlikely that sovereign states would vest unlimited control over domestic emissions to an international agency, and alternative regimes based on negotiated emission standards, emission taxes and marketable pollution permits are considered. Based on a subjective assessment of resource and transactions costs, a system of marketable emission permits may be least cost.

description: We propose a simple string bit formalism for interacting strings in a plane wave background, in terms of supersymmetric quantum mechanics with a symmetric product target-space. We construct the light-cone supersymmetry generators and Hamiltonian at finite string coupling. We find a precise match between string amplitudes and the non-planar corrections to the correlation functions of BMN operators computed from gauge theory, and conjecture that this correspondence extends to all orders in perturbation theory. We also give a simple RG explanation for why the effective string coupling is g_2 = J^2/N instead of g_s = g_{ym}^2.

description: Economic statistics can be used to inform policy as it is being designed, avoid policy design mistakes, or implement government programs once they are established into law. Oftentimes, statistics are used for all three purposes. This paper considers the relationships between statistics and agricultural policy in the case of the United States. We address first the broad historical picture of U.S. official economic statistics concerning agriculture, and then turn to selected examples that relate policies to economic statistics in more detail. The examples show diversity in the interplay between statistics and policy. As policies have become broader in scope, addressing not only farm commodity markets but also differences among farms and a widening set of activities on farms, policymakers have asked for more detailed information about the financial situation of individual farm businesses and households, sources of risk in farm returns, and production practices that affect the environment.

description: We consider the compressible Navier--Stokes equation in a perturbed half-space with an outflow boundary condition as well as the supersonic condition. For a half-space, it has been known that a certain planar stationary solution exist and it is time-asymptotically stable. The planar stationary solution is independent of the tangential directions and its velocities of the tangential directions are zero. In this paper, we show the unique existence of stationary solutions for the perturbed half-space. The feature of our work is that our stationary solution depends on all directions and has multidirectional flow. Furthermore, we also prove the asymptotic stability of this stationary solution.
Calculating exclusion limits for Weakly Interacting Massive Particle direct detection experiments without background subtraction

Subjects: subject: Astrophysics (astro-ph)

description: Competitive limits on the weakly interacting massive particle (WIMP) spin-independent scattering cross section are currently being produced by 76Ge detectors originally designed to search for neutrinoless double beta decay, such as the Heidelberg-Moscow and IGEX experiments. In the absence of background subtraction, limits on the WIMP interaction cross section are set by calculating the upper confidence limit on the theoretical event rate, given the observed event rate. The standard analysis technique involves calculating the 90% upper confidence limit on the number of events in each bin, and excluding any set of parameters (WIMP mass and cross-section) which produces a theoretical event rate for any bin which exceeds the 90% upper confidence limit on the event rate for that bin. We show that, if there is more than one energy bin, this produces exclusion limits that are actually at a lower degree of confidence than 90%, and are hence erroneously tight. We formulate criteria which produce true 90% confidence exclusion limits in these circumstances, including calculating the individual bin confidence limit for which the overall probability that no bins exceeds this confidence limit is 90% and calculating the 90% minimum confidence limit on the number of bins which exceed their individual bin 90% confidence limits. We then compare the limits on the WIMP cross-section produced by these criteria with those found using the standard technique, using data from the Heidelberg-Moscow and IGEX experiments.

description: As international agricultural markets become increasingly more integrated, internationally harmonized farm classification systems could become more useful for international comparisons of agricultural industries, as a tool for summarizing and analyzing micro-level data. Canada, Mexico, and the United States currently do not have a common farm classification system beyond the harmonized North American Industrial Classification System (NAICS), which the three countries developed and adopted shortly after the implementation of the North American Free Trade Agreement (NAFTA). While common policy themes exist among the three countries, such as competitiveness, innovation and sustainability, they have yet to be reflected in a comprehensive farm classification system. This paper compares farm structures in North America, using the NAICS and farm size. Additional classifications that are used in North America are summarized. Additional farm characteristics that could enhance the comprehensiveness of farm classification systems are discussed. Finally, data constraints which limit the ability to develop a harmonized classification system in the three jurisdictions are discussed.

description: Erosion of agricultural croplands is a significant contributor of sedimentation to reservoirs. Here, physiographic and economic models for a large agricultural watershed (2377 square miles with 27 subwatersheds) are integrated for the reduction of sedimentation of one Midwestern reservoir. Sediment reduction and the cost-effectiveness of three agricultural best management practices (no-till, filter strip, and permanent vegetation) implementation were considered under three modeling scenarios: random assignment; the globally most cost- effective approach; and a cost-effective targeting approach. This study demonstrates how physiographic and economic data can be harnessed to yield readily comprehendible cost-effective targeting maps. Cost-effective targeting may be preferable to watershed managers for its ‘‘user-friendliness’’ without too great a sacrifice of the globally most cost-efficient solution.

Eight of the nuclides, $^{161}$Pm, $^{163}$Sm, $^{164,165}$Eu, $^{167}$Gd, and $^{165,167,168}$Tb, were measured for the first time. The systematics of the mass surface has been studied via one- and two-neutron separation energies as well as neutron pairing-gap and shell-gap energies. The proton-neutron pairing strength has also been investigated. The impact of the new mass values on the astrophysical rapid neutron capture process has been studied. The calculated abundance distribution results in a better agreement with the solar abundance pattern near the top of the rare-earth abundance peak at around $A\approx165$.

Whereas a fractional D3-brane on the resolved conifold is not supersymmetric and has a naked singularity, our solution is supersymmetric and regular everywhere. We also consider an $S^1$-wrapped D3-brane on the resolved cone over T^{1,1}/Z_2, as well as on the deformed conifold. In the former case, we obtain a regular supergravity dual to a certain four-dimensional field theory whose Lorentz and conformal symmetries are broken in the IR region and restored in the UV limit.

Bose-glass phase of a one-dimensional disordered Bose fluid: metastable states, quantum tunneling and droplets

Subjects: subject: Quantum Gases (cond-mat.quant-gas)

description: We study a one-dimensional disordered Bose fluid using bosonization, the replica method and a nonperturbative functional renormalization-group approach. We find that the Bose-glass phase is described by a fully attractive strong-disorder fixed point characterized by a singular disorder correlator whose functional dependence assumes a cuspy form that is related to the existence of metastable states. At nonzero momentum scale $k$, quantum tunneling between the ground state and low-lying metastable states leads to a rounding of the cusp singularity into a quantum boundary layer (QBL). The width of the QBL depends on an effective Luttinger parameter $K_k\sim k^θ$ that vanishes with an exponent $θ=z-1$ related to the dynamical critical exponent $z$. The QBL encodes the existence of rare "superfluid" regions, controls the low-energy dynamics and yields a (dissipative) conductivity vanishing as $ω^2$ in the low-frequency limit. These results reveal the glassy properties (pinning, "shocks" or static avalanches) of the Bose-glass phase and can be understood within the "droplet" picture put forward for the description of glassy (classical) systems.

description: Background: Retirement, one of the major life transitions for middle-aged and older people, results in changes in the individual’s daily routine and time allocation. Previous findings suggested that retirement provides a good opportunity for people to adapt to a new lifestyle, and physical activity (PA) increases with retirement. However, the impact of PA on the older population over 75 years old remains unclear, and evidence regarding the type and intensity of PA is inconsistent in the previous literature. Purpose: To examine the association of retirement and Leisure-time physical activity (LTPA) among middle-aged and older US adults. Methods: The study sample consisted of participants aged 55 years and older (N = 148,849; Female = 52.9%) from the Behavioral Risk Factor Surveillance System (2017). Employment status, LTPA, and other social-demographic characteristics were self-reported by participants. The primary outcome was LTPA, for which we included 3 aspects -- PA participation, guidelines compliance, and PA intensity -- to capture the characteristics of LTPA. Binary logistic regression was conducted to explore the relationship between retirement and LTPA variables in each 5-year age group for both genders. Results: Overall 88,293 participants were retired (M = 44.5%, F = 55.5%). Retired men had higher odds (OR 1.04; 95% CI 1.00-1.07) of participating in the exercise in the past 30 days relative to employed men; retired women had lower odds (OR 0.77; 95% CI 0.75-0.80) relative to employed women to exercise in the past 30 days. Retirement was associated with higher odds of meeting the aerobic recommendations for both men (OR 1.33; 95% CI 1.29-1.37) and women (OR 1.06; 95% CI 1.03-1.09) and the same association was observed in most of the age groups. Retirement was associated with higher odds for men (OR 1.04; 95% CI 1.00-1.07) and lower odds for women (OR 0.91; 95% CI 0.88-0.94) of meeting the muscle-strengthening recommendations; the associations, however, varied by age group for both genders. Additionally, retirement was associated with lower odds of participating in moderate PA, but higher odds of participating in vigorous PA. Conclusion: Retirement is associated with an increase in LTPA for both genders. Aerobic activity is the major contributor to the LTPA with retirement, while muscle-strengthening activity is less influenced by the retirement status, which highlights the need for promoting muscle-strengthening activity among the middle-aged and older population.

description: Government support uncertainty, scarce yiel d information, and the inherent risk in bio- economic phenomena are some of the deterrents faced by investors in the nascent cellulosic biofuel industry. A financial probabilistic model was developed to contrast the economic feasibility of producing cellulosic biofuels from energy cane and sweet sorghum using three technologies: hydrolysis, pyrolysis, and gasification. Hydrolysis and pyrolysis proved feasible (showed possibilities of a positive net present value) without government support and conditioned to stochastic feedstock yields and biofuel prices. Gasification was feasible with government support. Improved feedstock and biofuel productivity would considerably raise the feasibility probabilities for hydrolysis and pyrolysis without government support.

description: Using mixtures of soap, water, and long chain polymers, free-floating soap bubbles can be formed with volumes approaching 100 m$^3$. Here we investigate how such thin films are created and maintained over time. We show how the extensional rheology is the most important factor in creating the bubble, and how polydispersity in molecular weight of the solvated polymers leads to better performance at lower concentrations. Additionally, using IR absorption, we measure soap film thickness profiles and film lifetimes. Although the initial thickness mostly depends on the choice of detergent, polymers can dramatically increase film lifetime at high molecular weights and high concentrations, although such high concentrations can inhibit the initial film formation. Thus, the ideal concentration of polymer additives for making giant bubbles requires a robust viscoelastic rheology during extension, and is aided by long film lifetimes during gravitational drainage and evaporation.

description: We examine how much on-farm reservoirs can increase groundwater quantity and improve surface water quality using a spatial-dynamic model of farm profit maximization in the Arkansas Delta. Sensitivity analysis of the farm profit objective by including the value of surface water quality and the groundwater buffer value evaluates how accounting for environmental value affects the optimal crop mix, water use, and farm profits. The best policy for a critical water resource area is to have the government cost share construction of on-farm reservoirs because groundwater conservation and surface water quality goals are achieved efficiently for a modest redistribution of income.

description: We quantify weather effects on output and incomes for a panel of Kansas farmers. The effects of weather are largely asymmetric with negative temperature and precipitation values affecting output and income differently than above average observations. Precipitation effects depend on timing and seasonal averages. The number of days exceeding 32.2°C (i.e., the ‘‘hot’’ years) negatively impacts production and income measures, although the impact is positive for crop output in the cooler years. The results indicate the importance of including weather in predicting output and income and designing risk management instruments to mitigate weather trends and variability.

description: We derive non-asymptotic quantitative bounds for convergence to equilibrium of the exact preconditioned Hamiltonian Monte Carlo algorithm (pHMC) on a Hilbert space. As a consequence, explicit and dimension-free bounds for pHMC applied to high-dimensional distributions arising in transition path sampling and path integral molecular dynamics are given. Global convexity of the underlying potential energies is not required. Our results are based on a two-scale coupling which is contractive in a carefully designed distance.

description: A new viewpoint for the gauge hierarchy problem is proposed: compactification at a large scale, 1/R, leads to a low energy effective theory with supersymmetry softly broken at a much lower scale, α/R. The hierarchy is induced by an extremely small angle αwhich appears in the orbifold compactification boundary conditions. The same orbifold boundary conditions break Peccei-Quinn symmetry, leading to a new solution to the μproblem. Explicit 5d theories are constructed with gauge groups SU(3) \times SU(2) \times U(1) and SU(5), with matter in the bulk or on the brane, which lead to the (next-to) minimal supersymmetric standard model below the compactification scale. In all cases the soft supersymmetry-breaking and μparameters originate from bulk kinetic energy terms, and are highly constrained. The supersymmetric flavor and CP problems are solved.

description: Factors associated with purchase likelihoods and amounts spent on fresh and preserved vegetables in Malaysia are investigated. A sample selection system is applied to data from a national survey in Malaysia. Statistical test supports separate analyses for urban and rural households. Income and sociodemographic characteristics such as ethnicity, location of residence, household size, and education are closely associated with household expenditure patterns of fresh and preserved vegetables. Urban–rural differences are also uncovered in these effects. Several observations are noted vis-a-vis the expenditure patterns for fresh and preserved vegetables in Malaysia.

description: The commitment of the government in promoting and encouraging the welfare of cocoa farmers makes cocoa policies critical in Ghana. Having dropped below global production levels, however, technical efficiency in Ghana has continued to decline over the years. This study aims to analyse the extent of productivity and find the sources of technical efficiency in cocoa-producing households by applying the stochastic frontier approach to the Ghana-Living Standards Survey Round Five of 2005/06. The estimated technical efficiency has a mean of 47.82%. Crop diversification, mechanised farming and hired labour enhance technical efficiency, while emigration results in its deterioration. Other critical factors that influence efficiency are also identified.

description: The objective of this study is to estimate Korean consumers’ willingness to pay (WTP) for beef products with BSE testing and country of origin labeling. We use a choice experiment to examine consumers’ valuation for beef products with these labels. In addition to analysis using the pooled sample, we also conduct sub-sample analyses based on consumers’ level of risk perception about beef consumption and selected socio-demographic characteristics. Results suggest that Korean consumers value BSE tested beef. They also have a preference for domestic beef vis-à-vis imported beef. Results also suggest that those with high risk perception tend to value BSE testing more than country of origin labeling while those with low risk perception value country of origin labeling more than BSE testing. Moreover, we found that young or high educated respondents tend to value BSE testing and imported beef from countries which have not experienced BSE outbreaks more than do older or lower educated respondents.
