description: We count the number of pairs in the single j-shell model of {44}Ti for various interactions. For a state of total angular momentum I, the wave function can be written in terms of the probability amplitude D(Jp Jn) that the protons couple to Jp and the neutrons to Jn. For I=0 there are three states with (I=0,T=0) and one with (I=0,T=2). The latter is the double analog of {44}Ca. In that case (T=2), the magnitude of D(JJ) is the same as that of a corresponding two-particle fractional parentage coefficient. In counting the number of pairs with an even angular momentum J, we find a new relationship obtained by diagonalizing a unitary nine-j symbol. We are also able to get results for the `no-interaction' case for T=0 states, for which it is found, e.g., that there are less (J=1,T=0) pairs than on the average. Relative to this `no-interaction case', we find for the most realistic interaction used that there is an enhancement of pairs with angular momentum J=0,2,1 and 7, and a depletion for the others. Also considered are interactions in which only the (J=0,T=1) pair state is at lower energy, only the (J=1,T=0) pair state is lowered and where both are equally lowered, as well as the QQ interaction. We are also able to obtain simplified formulae for the number of J=0 pairs for the I=0 states in {46}Ti and {48}Ti by noting that the unique state with isospin |Tz|+2 is orthogonal to all the states with isospin |Tz|.

description: The collective dynamics of $N$ weakly coupled processive molecular motors are considered theoretically. We show, using a discrete lattice model, that the velocity-force curves strongly depend on the effective dynamic interactions between motors and differ significantly from a simple mean field prediction. They become essentially independent of $N$ if it is large enough. For strongly biased motors such as kinesin this occurs if $N\gtrsim 5$. The study of a two-state model shows that the existence of internal states can induce effective interactions.

Do Farmers Need Tax-Deferred Savings Accounts to Help Manage Income Risk?

name: Monke, James D.
Publisher: name: Unknown
Year: 1997
Subjects: Agricultural Finance

description: Farmers' incomes vary with market conditions and yields. The Federal Agriculture Improvement and Reform Act of 1996 places more risk management responsibility on farmers. Savings accounts are one mechanism that could help farmers manage their income variability. Tax incentives have been proposed to encourage the use of such savings accounts, with benefits expected to accrue both to individual farmers and their communities. Participation rules tied to farm income may favor larger, more prosperous farmers. Because many farmers already save or use other methods to smooth household consumption, tax-advantaged accounts may largely substitute for existing risk management methods and offer limited additional overall benefits to the farm sector and rural areas.

Using data from USDA's Agricultural Resource Management Study (ARMS, formerly known as the Farm Costs and Returns Survey), we examine farm size, financial structure, household income, management practices, and spousal participation in decision-making. We compare broiler operations with other farming enterprises and their earnings with that of the average U.S. household. Because most of the 7 billion broilers produced in the United States in 1995 were raised under contract, we also explore the use of contracts and the effects of contracting on the broiler sector.

description: The number of farms and other estates that must pay Federal estate taxes has increased in recent years. Concerns about this increase and its effect on farms and other small businesses have generated a number of proposals to change Federal estate tax laws. Some proposals would affect only farms and small businesses. Other proposals would lower taxes for all estates and reduce the number of estates required to file an estate tax return. Of the current proposals examined here, farm estate taxes would be reduced most by a new exclusion for familyowned businesses, including farms.

description: The earned income tax credit (EITC) has become a major source of income support for low-income rural workers and their families, especially in the South, where the rural poor are concentrated. Program benefits for rural areas are expected to total about $6 billion in 1996, nearly double the 1992 amount, providing benefits to an estimated 4.5 million low-income rural workers and their families. Increasing concerns about escalating costs and the targeting of benefits may result in changes to the EITC program that would reduce both benefit levels and the number of eligible low-income rural workers. Proposed changes to improve the targeting of benefits would exclude many farmers from the program.
Normal Heat Conductivity in a strongly pinned chain of anharmonic oscillators

description: We consider a chain of coupled and strongly pinned anharmonic oscillators subject to a non-equilibrium random forcing. Assuming that the stationary state is approximately Gaussian, we first derive a stationary Boltzmann equation. By localizing the involved resonances, we next invert the linearized collision operator and compute the heat conductivity. In particular, we show that the Gaussian approximation yields a finite conductivity $κ\sim\frac{1}{λ^2T^2}$, for $λ$ the anharmonic coupling strength.

It allows determination of sin^2θ_{12} to the accuracy of \simeq 2% at 1 σCL, which surpasses all the method so far proposed. Unlike reactor θ_{13} experiments, the requirement for the systematic error is very mild, \simeq 4%, which makes it an even more feasible experiment. If we place a detector at \sim 60 km away from the Kashiwazaki-Kariwa nuclear power plant, 0.5 kt yr exposure of SADO is equivalent to \sim 100 kt yr exposure of KamLAND assuming the same systematic error.

The pressure distribution in thermally bistable turbulent flows

Publisher: name: arXiv
Year: 2005

description: We present a systematic numerical study of the effect of turbulent velocity fluctuations on the thermal pressure distribution in thermally bistable flows. The simulations employ a random turbulent driving generated in Fourier space rather than star-like heating. The turbulent fluctuations are characterized by their rms Mach number M and the energy injection wavenumber, k_for. Our results are consistent with the picture that as either of these parameters is increased, the local ratio of turbulent crossing time to cooling time decreases, causing transient structures in which the effective behavior is intermediate between the thermal-equilibrium and adiabatic regimes. As a result, the effective polytropic exponent gamma_ef ranges between ~0.2 to ~1.1. The fraction of high-density zones with P>10^4 Kcm^-3 increases from roughly 0.1% at k_for=2 and M=0.5 to roughly 70% for k_for=16 and M=1.25. A preliminary comparison with the pressure measurements of Jenkins (2004) favors our case with M=0.5 and k_for=2. In all cases, the dynamic range of the pressure summed over the entire density range, typically spans 3-4 orders of magnitude. The total pressure histogram widens as the Mach number is increased, and develops near-power-law tails at high (resp.low) pressures when gamma_ef~ 1), which occurs at k_for=2 (resp.k_for=16) in our simulations. The opposite side of the pressure histogram decays rapidly, in an approx. lognormal form. Our results show that turbulent advection alone can generate large pressure scatters, with power-law high-P tails for large-scale driving, and provide validation for approaches attempting to derive the shape of the pressure histogram through a change of variable from the known form of the density histogram, such as that performed by MacLow et al.(2004).

Bars formed in galaxy merging and their classification with deep learning

description: Stellar bars are a common morphological feature of spiral galaxies. While it is known that they can form in isolation, or be induced tidally, few studies have explored the production of stellar bars in galaxy merging. We look to investigate bar formation in galaxy merging using methods from deep learning to analyse our N-body simulations. The primary aim is to determine the constraints on the mass ratio and orientations of merging galaxies that are most conducive to bar formation. We further aim to explore whether it is possible to classify simulated barred spiral galaxies based on the mechanism of their formation. We test the feasibility of this new classification schema with simulated galaxies. Using a set of 29,400 images obtained from our simulations, we first trained a convolutional neural network to distinguish between barred and non-barred galaxies. We then tested the network on simulations with different mass ratios and spin angles. We adapted the core neural network architecture for use with our additional aims. We find that a strong inverse relationship between mass ratio and the number of bars produced. We also identify two distinct phases in the bar formation process; (1) the initial, tidally induced formation pre-merger, and (2) the destruction and/or regeneration of the during and after the merger. Mergers with low mass ratios and closely-aligned orientations are considerably more conducive to bar formation compared to equal-mass mergers. We demonstrate the flexibility of our deep learning approach by showing it is feasible to classify bars based on their formation mechanism.

description: It has been suggested that Gamma Ray Bursts (GRB) may enable the expansion rate of our Universe to be measured out to very high redshifts ($z \gsim 5$) just as type Ia supernovae have done at $z \sim$1--1.5. We explore this possibility here, and find that GRB have the potential to detect dark energy at high statistical significance, but they are unlikely to be competitive with future supernovae missions, such as SNAP, in measuring the properties of the dark energy. The exception to this conclusion is if there is appreciable dark energy at early times, in which case the information from GRB's will provide an excellent complement to the $z\sim 1$ information from supernovae.

description: We discuss the incorporation of quarks in the fundamental representation of the color group into the non-critical string/gauge duality. We focus on confining theories and address this question using two different approaches: (i) by introducing flavor probe branes and (ii) by deriving backreacted flavored near extremal gravity backgrounds. In the former approach we analyze the near extremal AdS_6 model with D4 and anti-D4 probe flavor branes included. We study the meson spectrum and discuss the role played by the constituent quark mass, related to the integration constant that defines the embedding. As for the second approach we derive a class of flavored AdS_{n+1} x S^k black hole solutions. In particular we write down the flavored AdS_6 and AdS_5 black holes and the near extremal AdS_5 x S^1 backgrounds. We analyze several gauge dynamical properties associated with these models.

description: Background: Meeting the growing industry demand for Data Science requires cross-disciplinary teams that can translate machine learning research into production-ready code. Software engineering teams value adherence to coding standards as an indication of code readability, maintainability, and developer expertise. However, there are no large-scale empirical studies of coding standards focused specifically on Data Science projects. Aims: This study investigates the extent to which Data Science projects follow code standards. In particular, which standards are followed, which are ignored, and how does this differ to traditional software projects? Method: We compare a corpus of 1048 Open-Source Data Science projects to a reference group of 1099 non-Data Science projects with a similar level of quality and maturity. Results: Data Science projects suffer from a significantly higher rate of functions that use an excessive numbers of parameters and local variables. Data Science projects also follow different variable naming conventions to non-Data Science projects. Conclusions: The differences indicate that Data Science codebases are distinct from traditional software codebases and do not follow traditional software engineering conventions. Our conjecture is that this may be because traditional software engineering conventions are inappropriate in the context of Data Science projects.

We show that the latter is rooted in an interplay between a direct radiation process occurring due to temperature bias between two thermal baths and the modulation process which is responsible for pumped radiation heat. Our theoretical results are confirmed via time-domain simulations with RF circuits.

description: We use spectra and maps of NH2D, ND2H, and ND3, obtained with the CSO, IRAM 30m and Arecibo telescopes, to study deuteration processes in dense cores. The data include the first detection of the hyperfine structure of ND2H. The emission of ND2H and ND3 does not seem to peak at the positions of the embedded protostars, but instead at offset positions, where outflow interactions may occur. A constant ammonia fractionation ratio in star-forming regions is generally assumed to be consistent with an origin on dust grains. However, in the pre-stellar cores studied here, the fractionation varies significantly when going from NH3 to ND3. We present a steady state model of the gas-phase chemistry for these sources, which includes passive depletion onto dust grains and multiply saturated deuterated species up to five deuterium atoms (e.g. CD5+). The observed column density ratios of all four ammonia isotopologues are reproduced within a factor of 3 for a gas temperature of 10 K. We also predict that deuterium fractionation remains significant at temperatures up to 20 K. ND and NHD, which have rotational transitions in the submillimeter domain are predicted to be abundant.

description: Results on $B \to μ^+ μ^-$ decays with the CMS experiment are reported, using 61 fb$^{-1}$ of data recorded during LHC Run 1 and 2016. With an improved muon identification algorithm and refined unbinned maximum likelihood fitting methods, the decay $B_s^0 \to μ^+ μ^-$ is observed with a significance of 5.6 standard deviations. Its branching fraction is measured to be BF($B^0_s \to μ^+ μ^-$) = [2.9+/-0.7(exp)+/-0.2(frag)]$\times 10^{-9}$, where the first error is the combined statistical and systematic uncertainty and the second error quantifies the uncertainty of the $B^0_s$ and $B^+$ fragmentation probability ratio. The $B^0_s \to μ^+ μ^-$ effective lifetime is $τ_{μ^+ μ^-} =1.70^{+0.61}_{-0.44}$ps. No evidence for the decay $B^0 \to μ^+ μ^-$ is found and an upper limit of BF($B^0 \to μ^+ μ^-$) < 3.6$\times 10^{-10}$ (at 95% confidence level) is determined. All results are consistent with the standard model of particle physics.

Although the anomaly cancellation conditions typically include cubic equations with integer variables that cannot be solved in general, we prove by construction that any chiral set of fermions can be embedded in a larger set of fermions which is chiral and anomaly-free. Applying these techniques to extensions of the Standard Model, we find anomaly-free models that have arbitrary quark and lepton charges under an additional U(1) gauge group.

description: Persistence of price-cost margins in the U.S. food and tobacco manufacturing industries is measured while accounting for price-cost margin risk. Direct measurement of persistence and of long- and short-run price-cost margin risk is accomplished by incorporating a partial-adjustment framework into the Single Index Model. Results indicate persistence of price-cost margins. Short-run margin risk is accounted for primarily by diversifiable risk. Long-run margin risk, which depends on systematic risk alone, is generally lower than the short-run measure. Factors influencing persistence and the systematic relationship between industry margins and a market index are explored.
Conceptualizing autonomy for education
Creators: name: Kerr, Donald
Publisher: name: University of British Columbia
Year: 2009

description: In this thesis I develop a conceptualization of autonomy that, I argue, is not only defensible within liberal theory, but does not succumb to prominent criticisms raised of that theory. To do this I examine the requirements for a conceptualization of autonomy provided by our understanding of the tenets of liberalism, and also by the legitimate criticisms of liberalism raised by feminist and communitarian theorists. In particular I consider concerns about relational as opposed to atomistic conceptions of the self. I outline the criteria that a conceptualization of autonomy must meet if it is to be both useful and defensible, and I examine several prominent versions of autonomy against these criteria and show how I believe they fail to fulfill them adequately. I argue that conceptualizations of autonomy as sets of cognitive skills and abilities do not capture the criterion that a useful conceptualization reflect the liberal requirements of demonstrating an ability to act congruently with the demands of justice and equality. And conceptualizations of autonomy that discuss it in terms of being able and willing to make good decisions, or the kinds of decisions necessary of citizens in liberal democracies, are unclear on whether an action or decision must itself be seen as good in order to be considered autonomous. I suggest that autonomy is best understood as a descriptor of decisions and actions that meet specific criteria, and I show that such a conceptualization is useful in our discussions about education.
New Anisotropic Sudden Singularities and Dimensional Reduction

description: We demonstrate the existence of sudden, finite-time, singularities, with constant scale factor, expansion rate and density, in expanding Bianchi type IX universes with free anisotropic pressures. A new type of non-simultaneous anisotropic sudden singularity arises because of the divergences of the pressures, which may be of barrel or pancake type. The effect of one or more directions of expansion hitting a sudden singularity is tantamount to dimensional reductions as the non-singular directions continue expanding and can see the sudden singularity in their past.

description: The number and volume of meat and poultry recalls has increased substantially in recent years. This is likely due to regulatory emphasis on foodborne illness resulting in an increased frequency of testing for pathogens. We use an equilibrium-displacement model to examine the effects of recall costs on the beef, pork, and poultry industries. Results suggest that higher recall costs may have actually increased producer surplus to the broiler industry because of consumer substitution among products and that most losses resulting from recalls are accruing to the beef and pork industries.

description: We explain how the axioms of Conformal Field Theory are used to make predictions about critical exponents of continuous phase transitions in three dimensions, via a procedure called the conformal bootstrap. The method assumes conformal invariance of correlation functions, and imposes some relations between correlation functions of different orders. Numerical analysis shows that these conditions are incompatible unless the critical exponents take particular values, or more precisely that they must belong to a small island in the parameter space.

description: Spring security is tremendously popular among practitioners for its ease of use to secure enterprise applications. In this paper, we study the application framework misconfiguration vulnerabilities in the light of Spring security, which is relatively understudied in the existing literature. Towards that goal, we identify 6 types of security anti-patterns and 4 insecure vulnerable defaults by conducting a measurement-based approach on 28 Spring applications. Our analysis shows that security risks associated with the identified security anti-patterns and insecure defaults can leave the enterprise application vulnerable to a wide range of high-risk attacks. To prevent these high-risk attacks, we also provide recommendations for practitioners. Consequently, our study has contributed one update to the official Spring security documentation while other security issues identified in this study are being considered for future major releases by Spring security community.
Low density spin-polarized transport in 2D semiconductor structures: The enigma of temperature dependent magnetoresistance of Si MOSFETs in an in-plane applied magnetic field

description: The temperature dependence of 2D magnetoresistance in an applied in-plane magnetic field is theoretically considered for electrons in Si MOSFETs within the screening theory for long-range charged impurity scattering limited carrier transport. In agreement with recent experimental observations we find an essentially temperature independent magnetoresistivity for carrier densities well into the 2D metallic regime due to the field-induced lifting of spin and, perhaps, valley degeneracies. In particular the metallic temperature dependence of the ballistic magnetoresistance is strongly suppressed around the zero-temperature critical magnetic field ($B_s$) for full spin-polarization, with the metallic temperature dependence strongest at B=0, weakest around $B \sim B_s$, and intermediate at $B \gg B_s$.

description: The purpose of this study was to identify how consumer perceptions of selected attributes of beef steaks, individual consumer demographics and perceived changes in purchases of substitute meats affect willingness-to-pay for beef rib-eye steaks in the traditional overwrapped styrofoam tray and vacuum skin packages. A laboratory auction was used to obtain willingness-to-pay data. The results suggest that health related factors, particularly the concern regarding cholesterol, reduced the willingness-to-pay for beef rib-eye steaks, regardless of package type. For the vacuum skin package to be successful, information about the package is necessary, along with providing a consistent and quality product, particularly with respect to trim.

description: A general mathematical framework for quantum key distribution based on the concepts of quantum channel and Turing machine is suggested. The security for its special case is proved. The assumption is that the adversary can perform only individual (in essence, classical) attacks. For this case an advantage of quantum key distribution over classical one is shown.

description: Identity documents automatic reading and verification is an appealing technology for nowadays service industry, since this task is still mostly performed manually, leading to waste of economic and time resources. In this paper the prototype of a novel automatic reading system of identity documents is presented. The system has been thought to extract data of the main Italian identity documents from photographs of acceptable quality, like those usually required to online subscribers of various services. The document is first localized inside the photo, and then classified; finally, text recognition is executed. A synthetic dataset has been used, both for neural networks training, and for performance evaluation of the system. The synthetic dataset avoided privacy issues linked to the use of real photos of real documents, which will be used, instead, for future developments of the system.

description: The motivation of this project was to investigate WSR-88D Doppler radar data and nearstorm environments to improve severe thunderstorm detection and verification across northern New York and Vermont. This research focused on assessing instability and shear parameters to identify near-storm environments conducive for severe thunderstorm development, along with establishing severe thunderstorm warning thresholds based on reflectivity (Z) and differential reflectivity (Zdr) values and heights.  All severe thunderstorm warnings and severe weather reports from the National Weather Service (NWS) Burlington, VT, (BTV) County Warning Area (CWA) from 2017 through 2019 during May, June, July, and August were examined. Rapid Refresh (RAP) proximity soundings were utilized to evaluate near-storm thermodynamic and vertical shear parameters. Storms were subsequently classified based on WSR-88D radar reflectivity characteristics into four distinct types; single cell (SC), multi-cell cluster (MCC), multi-cell linear (MCL), and supercell (SP). Radar interrogation of the 50 and 60 dBZ heights were examined, including vertical cross sections of reflectivity and differential reflectivity. An evaluation of traditional height-based reflectivity thresholds at 0°C, -10°C, and -20°C isotherm levels were investigated to identify critical warning thresholds.  The four distinct convective modes demonstrated a large range of environmental parameters conducive for producing severe weather across the BTV CWA. MCL events had the highest shear and lowest instability parameters, while displaying the lowest (Z) and (Zdr) columns. Additionally, if a Zdr column of 3 dB or greater was present above the -10°C isotherm, severe weather was observed 89% of the time and 63% of the time if above the 0°C isotherm.

description: The aim of this work is to efficiently and robustly solve the statistical inverse problem related to the identification of the elastic properties at both macroscopic and mesoscopic scales of heterogeneous anisotropic materials with a complex microstructure that usually cannot be properly described in terms of their mechanical constituents at microscale. Within the context of linear elasticity theory, the apparent elasticity tensor field at a given mesoscale is modeled by a prior non-Gaussian tensor-valued random field. A general methodology using multiscale displacement field measurements simultaneously made at both macroscale and mesoscale has been recently proposed for the identification the hyperparameters of such a prior stochastic model by solving a multiscale statistical inverse problem using a stochastic computational model and some information from displacement fields at both macroscale and mesoscale. This paper contributes to the improvement of the computational efficiency, accuracy and robustness of such a method by introducing (i) a mesoscopic numerical indicator related to the spatial correlation length(s) of kinematic fields, allowing the time-consuming global optimization algorithm (genetic algorithm) used in a previous work to be replaced with a more efficient algorithm and (ii) an ad hoc stochastic representation of the hyperparameters involved in the prior stochastic model in order to enhance both the robustness and the precision of the statistical inverse identification method. Finally, the proposed improved method is first validated on in silico materials within the framework of 2D plane stress and 3D linear elasticity (using multiscale simulated data obtained through numerical computations) and then exemplified on a real heterogeneous biological material (beef cortical bone) within the framework of 2D plane stress linear elasticity (using multiscale experimental data obtained through mechanical testing monitored by digital image correlation).

description: We present a state-of-the-art evaluation of the polarizability corrections--the inelastic nucleon corrections--to the hydrogen ground-state hyperfine splitting using analytic fits to the most recent data. We find a value $Δ_{\rm pol} = 1.3 \pm 0.3$ ppm. This is 1--2 ppm smaller than the value of $Δ_{\rm pol}$ deduced using hyperfine splitting data and elastic nucleon corrections obtained from modern form factor fits.
