Canonical and DLPNO-based G4(MP2)XK-inspired composite wavefunction methods parametrized against large and chemically diverse training sets: Are they more accurate and/or robust than double hybrid DFT?

description: The large and chemically diverse GMTKN55 benchmark was used as a training set for parametrizing composite wave function thermochemistry protocols akin to G4(MP2)XK theory (Chan et al, JCTC 2019, 15, 4478-4484). Even after reparametrization, the GMTKN55 WTMAD2 (weighted mean absolute deviation, type 2) for G4(MP2)-XK is actually inferior to that of the best rung-4 DFT functional, wB97M-V. By increasing the basis set for the MP2 part to def2-QZVPPD, we were able to substantially improve performance at modest cost (if an RI-MP2 approximation is made), with WTMAD2 for this G4(MP2)-XK-D method now comparable to the better rung-5 functionals (albeit at greater cost). A three-tier approach with a scaled MP3/def2-TZVPP intermediate step, however, leads to a G4(MP3)-D method that is markedly superior to even the best double hybrids wB97M(2) and revDSD-PBEP86-D4. Evaluating the CCSD(T) component with a triple-zeta, rather than split-valence, basis set yields only a modest further improvement that is incommensurate with the drastic increase in computational cost. G4(MP3)-D and G4(MP2)- XK-D have about 40% better WTMAD2, at similar or lower computational cost, than their counterparts G4 and G4(MP2), respectively: detailed comparison reveals that the difference lies in larger molecules due to basis set incompleteness error. An E2/ {T,Q} extrapolation and a CCSD(T)/def2-TZVP step provided the G4-T method of high accuracy and with just three fitted parameters. Using KS orbitals in MP2 leads to the G4(MP3|KS)-D method, which entirely eliminates the CCSD(T) step and has no steps costlier than scaled MP3; this shows a path forward to further improvements in double-hybrid density functional methods. G4-T-DLPNO, a variant in which post-MP2 corrections are evaluated at the DLPNO- CCSD(T) level, achieves nearly the accuracy of G4-T but is applicable to much larger systems.

description: In this paper, we study the social efficiency of private carbon markets that include trading in agricultural soil carbon sequestration when there are significant co-benefits (positive environmental externalities) associated with the practices that sequester carbon. Likewise, we investigate the efficiency of government-run conservation programs that are designed to promote a broad array of environmental attributes (both carbon sequestration and its co-benefits) for the supply of carbon. Finally, policy design and efficiency issues associated with the potential interplay between a private carbon market and a government conservation program are studied. Empirical analyses for an area that represents a significant potential source of carbon sequestration and its associated co-benefits illustrate the magnitude and complexity of these issues in real-world policy design.

description: When is a nonlinear filter stable with respect to its initial condition? In spite of the recent progress, this question still lacks a complete answer in general. Currently available results indicate that stability of the filter depends on the signal ergodic properties and the observation process regularity and may fail if either of the ingredients is ignored. In this note we address the question of stability in a particular weak sense and show that the estimates of certain functions are always stable. This is verified without dealing directly with the filtering equation and turns to be inherited from certain one-step predictor estimates.

description: We present a real options model of an agent's decision to purchase or sell a good under conditions of uncertainty, irreversibility, and learning over time. Her WTP and WTA contain both the intrinsic value of the good and an option value associated with delaying the decision until more information is available. Consequently, the standard Hicksian equivalence between WTP/WTA and compen-sating and equivalent variation no longer holds. This helps to explain the WTP/WTA disparity often observed in laboratory experiments and surveys because subjects may have limited learning time and opportunities, thus generating option values. In contrast, the disparity may decrease or disappear entirely in real markets since agents are free to choose when to stop gathering information, thereby reducing or eliminating the option values. We also discuss experimental evidence that supports the option value hypothesis.

description: Emotion states recognition using wireless signals is an emerging area of research that has an impact on neuroscientific studies of human behaviour and well-being monitoring. Currently, standoff emotion detection is mostly reliant on the analysis of facial expressions and/or eye movements acquired from optical or video cameras. Meanwhile, although they have been widely accepted for recognizing human emotions from the multimodal data, machine learning approaches have been mostly restricted to subject dependent analyses which lack of generality. In this paper, we report an experimental study which collects heartbeat and breathing signals of 15 participants from radio frequency (RF) reflections off the body followed by novel noise filtering techniques. We propose a novel deep neural network (DNN) architecture based on the fusion of raw RF data and the processed RF signal for classifying and visualising various emotion states. The proposed model achieves high classification accuracy of 71.67 % for independent subjects with 0.71, 0.72 and 0.71 precision, recall and F1-score values respectively. We have compared our results with those obtained from five different classical ML algorithms and it is established that deep learning offers a superior performance even with limited amount of raw RF and post processed time-sequence data. The deep learning model has also been validated by comparing our results with those from ECG signals. Our results indicate that using wireless signals for stand-by emotion state detection is a better alternative to other technologies with high accuracy and have much wider applications in future studies of behavioural sciences.

description: This paper adopts an approach based on the concepts of random utility maximization and builds on the general theoretical framework of Lancaster and on the conceptual and econometric innovations of McFadden. Recent research in this area explores models that account for context effects, as well as methods for characterizing heterogeneity, response variability and decision strategy selection by consumers. This makes it possible to construct much richer empirical models of individual consumer behavior. A Bayesian approach provides a useful way to estimate and interpret models that are difficult to accomplish by conventional maximization/minimization algorithms. The application reported in the paper involves analysis of reference dependence and product labeling as context effects and the assessment of heterogeneity and response variability.

description: We analyse the entanglement generation in a one dimensional scattering process. The two colliding particles have a Gaussian wave function and interact by hard--core repulsion.In our analysis results on the entanglement of two mode Gaussian states are used. The produced entanglement depends in a non-obvious way on the parameters ratio of masses and initial widths. The asymptotic wavefunction of the two particles and its associated ellipse yield additional geometric insight into these conditions. The difference to the quantitative analysis of the amount of entanglement generated by beam splitters with squeezed light is discussed.

description: The binary star system gamma Cephei is unusual in that it harbours a stable giant planet around the larger star at a distance only about a tenth of that of the stellar separation. Numerical simulations are carried out into the stability of test particles in the system. This provides possible locations for additional planets and asteroids. To this end, the region interior to the planet is investigated in detail and found to permit structured belts of particles. The region between the planet and the secondary star however shows almost no stability. The existence of an Edgeworth-Kuiper belt analogue is found to be a possibility beyond 65 au from the barycentre of the system, although it shows almost no structural features. Finally, the region around the secondary star is studied for the first time. Here, a zone of stability is seen out to 1.5 au for a range of inclinations. In addition, a ten Jupiter-mass planet is shown to remain stable about this smaller star, with the habitability and observational properties of such an object being discussed.

description: The EU has argued that some agricultural subsidies are needed to provide the optimal amount of externalities (both positive and negative) produced by agriculture. The argument is that agriculture is "multifunctional" and externalities such as rural development and landscape would be underproduced, while some forms of pollution (such as nitrogen runoff) would be overproduced without government intervention. Meanwhile, the United States has raised the concern that multifunctionality is primarily an argument to transfer income to producers. In this paper, we discuss the motivation for the EU agri-environmental measures and empirically test for those underlying causes. We find that the programs are not targeted at those regions with the highest environmental need, but neither are they purely a substitute for traditional forms of agricultural subsidies. Demand for general environmental expenditure does influence agri-environmental expenditure as well, as does political structure.

description: The heaviest neutron stars and lightest black holes expected to be produced by stellar evolution leave the mass-range $2.2$ M$_{\odot}\lesssim m \lesssim 5$ M$_\odot$ largely unpopulated. Objects found in this so-called lower mass gap likely originate from a distinct astrophysical process. Such an object, with mass $2.6$ M$_\odot$ was recently detected in the binary merger GW190814 through gravitational waves by LIGO/Virgo. Here we show that black holes in the mass gap are naturally assembled through mergers and accretion in AGN disks, and can subsequently participate in additional mergers. We compute the properties of AGN-assisted mergers involving neutron stars and black holes, accounting for accretion. We find that mergers in which one of the objects is in the lower mass gap represent up to $4$% of AGN-assisted mergers detectable by LIGO/Virgo. The lighter object of GW190814, with mass $2.6$ M$_\odot$, could have grown in an AGN disk through accretion. We find that the unexpectedly high total mass of 3.4 M$_\odot$ observed in the neutron star merger GW190425 may also be due to accretion in an AGN disk.

description: We derive, in model independent way, the spin structure of the matrix element for the reaction of associative $Θ^+$ pentaquark production, $π^{\pm}+D\to Θ^+ +Σ^{\pm}, $ in the threshold region and in collinear kinematics. The expressions for the polarization observables in this reaction are found assuming spin 1/2 and different parities for $Θ^+ .$ We have proved that such reaction can be used for a model independent determination of the P-parity of $Θ^+$ only by measuring the $Θ^+$ polarization. Other polarization observables, such as the dependence of the $Σ^{\pm}$ polarization on the vector and tensor deuteron polarizations, are insensitive to the $Θ^+$ parity in the considered kinematical conditions. All linear and quadratic relations between polarization observables in $π^{\pm}+\vec D\to Θ^+ +\vecΣ^{\pm}(Θ^+ $ is unpolarized) do not depend on the parity of the $Θ^+$ pentaquark.

description: With continuing trends in increasing farm size and declining number, the impact of size of operation on risk may have significant policy implications. Diversification indexes for 288 Kansas farms from 1984 to 2003 indicated that sample farms had become slightly more diversified over time. Previous findings on the impact of farm size on diversification of farms have been controversial. To capture observed size impacts on enterprise-specific risks, a mean-variance model that allows for variance of enterprise returns to be decreasing in assets allocated is conceptualized. Efficient farm enterprise mixes are estimated using farm level data, showing that the optimal levels of diversification differ for farms of different sizes. For example, small farms should diversify more than large farms to achieve the same level of return. Results from a panel regression analysis showed that the relationship between farm size and diversification depended on how farm size was measured, reconciling the past findings.

description: Massive MIMO is seen as a main enabler for low latency communications, thanks to its high spatial degrees of freedom. The channel hardening and favorable propagation properties of Massive MIMO are particularly important for multiplexing several URLLC devices. However, the actual utility of channel hardening and spatial multiplexing is dependent critically on the accuracy of channel knowledge. When several low latency devices are multiplexed, the cost for acquiring accurate knowledge becomes critical, and it is not evident how many devices can be served with a latency-reliability requirement and how many pilot symbols should be allocated. This paper investigates the trade-off between achieving high spectral efficiency and high reliability in the downlink, by employing various power allocation strategies, for maximum ratio and minimum mean square error precoders. The results show that using max-min SINR power allocation achieves the best reliability, at the expense of lower sum spectral efficiency.

description: Strange Nuggets are believed to be among the relics of the early universe. They appear as dark matter due to their low charge-to-mass ratio. Their distribution is believed to be the same as that of dark matter. As such, they could be accreted by high magnetic field objects and their collisions with pulsars are inevitable. Pulsar glitches are commonly seen as sudden spin-ups in pulsar frequency. It is still an open debate with regard to mechanisms giving rise to such a phenomenon. However, there is a class of sudden changes in pulsar spin frequency known as microglitches. These event are characterized by sudden small change in pulsar spin frequency ($ δν/ν\approx \pm 10^{-9}$). Clearly, the negative signature seen in some of the events is inconsistent with the known glitch mechanisms. In this analysis, we suggest that accretion of strange nuggets with pulsars could readily give rise to microglitch events. The signature of the events depends on the energy of the strange nuggets and line of interaction.

description: This research used survey data to measure baseline levels of (1) openness to diversity and (2) diversity experience for students enrolled in the College of Agriculture at Kansas State University in Fall semester, 2004. The study also used regression analysis to identify and quantify the determinants of student openness to diversity and challenge and the level of experience with diversity. Regression results found that the determinants of openness to diversity and challenge included: experience with diversity, gender, size of hometown, enrolled credit hours, desire to obtain an advanced degree, outside work experience, and major field of study. Student experience with diversity was defined as a measure of the degree to which students have interacted with individuals who are different from themselves in race, ethnicity, philosophy of life, politics, religious beliefs, race, or a different country. The level of experience with diversity was found to be statistically associated with participation in courses and workshops in diversity, ethnicity, urban background, parent education levels, and desire to obtain an advanced degree, and major field of study. The major implication of the statistical results is that there is an opportunity to influence student openness to diversity and challenge, since: (1) experience with diversity was shown to be a highly statistically significant determinant of openness to diversity and challenge, and (2) the levels of diversity experience in the College of Agriculture were low. Therefore, enhanced programming for diversity appreciation and understanding as part of the university experience is likely to provide higher measurable levels of openness to diversity and challenge among students and graduates of the College. The identification of student characteristics associated with openness to diversity allows students, faculty, and administrators information useful for addressing the planning, implementation, and consequences of institutional diversity programming.

description: During the 14-month period from May 2002 to June 2003, approximately 10 percent of U.S. supermarkets began to offer fresh irradiated ground beef under the stores' own labels. Using a survey of supermarket store managers from this time period, this paper investigates the factors that influenced new product offerings and adoptions. Results from the adoption model show that factors associated with competition and structure in the food retailing industry play a strong role in the decision. Among other results, we find that variables relating to a competitor's adoption status and proximity significantly affect a store's decision to offer fresh irradiated ground beef.

description: Economists who address economic development problems are in a position to contribute a great deal to reduce the disequilibria cited, to bring about a more efficient allocation of the world's resources, and to improve equity in the distribution of income on a global scale. Moreover, as will be explained below, I believe the American Agricultural Economic Association should do a great deal more to help the members of our profession to become more effectively involved in these important tasks. The remainder of my remarks is divided into three parts. The first section provides an analytical framework that can be used to address development problems in the international economy. In the second part contains a description of some of the opportunities available to economists in the international economy. In the third section I offer some suggestions on what the Association might do to expand the opportunities for its members to contribute to a more efficient, equitable allocation of the world's resources. At the end I will have some concluding comments.

description: The authors address the fundamental question, "How does one analyze the potential of a given product for a given market?" A review of the literature suggests that numerous authors have proposed a relatively consistent set of questions that need to be addressed, information sought and key issues to consider when conducting market assessments. The goal of this paper is to review this literature and assemble a set of references that provide insights on how to analyze the market potential of agricultural and food products. This process is of growing importance as U.S. agricultural producers and processors seek to market differentiated products, seek out direct marketing opportunities and focus on meeting consumer preferences for food product attributes.

description: We develop a multi-market equilibrium displacement model that allows for demand linkages (substitutes or complements) across downstream product markets, and supply linkages through the common use of a raw commodity as the key input. Applying the model to the dairy sector, we find that the effectiveness of producer-funded advertising, and thus optimal advertising intensities, depends on the demand relationships across dairy product markets (cross-price and cross-advertising elasticities), as well as the re-allocation of raw milk towards the advertised market. We argue that the previous literature, which ignores the horizontal linkages highlighted here, tends to overstate the effectiveness of generic commodity promotion for dairy, and thus results in too much advertising.

Because people in low-income neighborhoods may have fewer grocery stores and transportation alternatives, the effects of store size and competition on the price of a market basket is estimated.
The Role of Child Support in Texas Welfare Dynamics: Statistical Supplement for Local Workforce Development Areas
Creators: name: Schexnayder, Deanna T.

Publisher: name: Ray Marshall Center for the Study of Human Resources
Year: 1999
Subjects: Family and Social Policy

description: he Role of Child Support in Texas Welfare Dynamics was published in September 1998. That four-year study measured the influence that increased child support enforcement strategies had on Texas welfare dynamics in the period following the implementation of the Family Support Act but prior to passage of the Personal Responsibility and Work Opportunity Reconciliation Act of 1996, the country’s latest round of welfare reform. This supplement provides descriptive statistics about Texas’ adult welfare recipients and the noncustodial parents of their children for each of Texas’ 28 local workforce development areas. It should be used as a companion piece to the statewide publication and provides statistics about both welfare caretakers and noncustodial parents that are often difficult to obtain, especially at the substate level. With the increased emphasis on improving the employability of noncustodial parents in welfare families, these statistics should provide background information to guide local planners in developing appropriate services for this group.

An empirical application drawn from the Total Maximum Daily Load standard implemented to control in-stream water temperature pollution for the Navarro River watershed, located in northern California provides the basis for this inquiry.
Supersymmetric SO(10) for fermion masses and mixings: rank-1 structures of flavour
Creators: name: Berezhiani, Z.
name: Nesti, F.
Publisher: name: arXiv
Year: 2005
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)
subject: FOS: Physical sciences

description: We consider a supersymmetric SO(10) model with a SU(3) symmetry of flavour in which fermion masses emerge via the see-saw mixing with superheavy fermions in 16+16bar representations. In this model the dangerous D=5 operators of proton decay are naturally suppressed and flavour-changing supersymmetric effects are under control. The mass matrices for all fermion types (up and down quarks, charged leptons as well as neutrinos) appear in the form of combinations of three rank-1 matrices, common to all types of fermions, with different coefficients that are successive powers of small parameters, related to each other by SO(10) symmetry properties. Two versions of the model are considered, in which approximate grand unification of masses takes place between quarks and leptons of the first family (with very small \tanβ) or for the ones of the second family (predicting moderate \tanβ~ 7-8). The second version exhibits an interesting mechanism of unification of the determinants of the Yukawa matrices of all types of fermions at the GUT scale and it provides a perfect fit of the known data for fermion masses, mixing and CP-violation. It predicts a hierarchical pattern of neutrino masses with non-zero theta_e3, within 2-7 degrees. In addition, it predicts the correct sign of the baryon asymmetry of the Universe via the leptogenesys scenario.

Deformation under the constant stress state and its effect on stress-strain behaviour of Fraser River Sand
Creators: name: Shozen, Takahiro
Publisher: name: University of British Columbia
Year: 2009

description: This study was carried out to improve our understanding of the behaviour of Fraser River Sand during and after ageing The main objectives of this study are (a) the effects of ageing time under constant stress state on the stiffness of sand and (b) the effects of stress path during subsequent shear. Identical soil samples were aged under constant stresses for 1, 10, 100 and 1,000 minutes prior to shear along a variety of stress paths. The effects of the levels of confining stress and initial effective stress ratio on changes in stiffness due to ageing under a given stress path were also investigated. The effect of ageing time is recognized regardless of the condition applied under the triaxial test. The magnitude of the considerable increase occurs in shear modulus with increased holding duration. In addition, this increase becomes more significant when the ageing stress ratio is higher. Also, the ageing time effect seems to remain only within a small strain. The effects of applied stress paths are also observed. However, this effect is strongly dependant on the initial stress ratios.
PESTICIDES AND CHILD HEALTH: EVIDENCE FROM HISPANIC CHILDREN IN THE U.S.
Creators: name: MacInnis, Bo

Publisher: name: Unknown
Year: 2004
Subjects: Health Economics and Policy

description: This paper examines whether there is an externality of parental occupational exposure to pesticides on children's health, and whether some children are more severely affected by the externality than others. Using the Hispanic Health and Nutrition Examination survey, we find children of exposed parents are more likely to develop chronic conditions and less likely to attain good health than children of unexposed parents, after controlling for a large set of child and family characteristics. Furthermore, children from low socioeconomic status are most vulnerable to health shocks resulting from pesticides and other related environmental toxins. Our analysis suggests that terminating the pathway of parental occupational exposure would be cost effective to correct the externality. Taken together with earlier findings that poor childhood health is associated with lower adult earnings, our results suggest more attention to be paid to the health shocks from environmental toxins for the poor as a potential mechanism through which the increasing poverty across generations at the very poor takes place: poverty makes individuals more susceptible to health shocks at childhood, which is associated with worse poverty for their children.
MODELING STRUCTURAL CHANGE IN FRENCH BEEF, POULTRY, AND FISH DEMAND: A MARKOV SWITCHING AIDS MODEL

description: Structural change in the French demand of beef, poultry and fish is originally investigated. Rather than applying the traditional switching AIDS (S-AIDS) model, we reconsider the analysis of structural change through the Markov switching AIDS (MS-AIDS). The main feature of this model is that the switching mechanism is controlled by an unobserved variable that follows a Markov chain. As such, it captures more complex dynamic patterns than does the S-AIDS model. The MS-AIDS and the S-AIDS are compared to determine which model provides the better explanation of beef, poultry, and fish dynamic demand. We find that a MS-AIDS displaying habit formation detects the two mad cow crises in 1996 and 2000 and may identify the structural changes emanating from nutritional recommendations.
