description: Using the Karpman-Solov'ev method we derive the equations for the 2-soliton adiabatic interaction for solitons of the modified nonlinear Schrodinger equation (MNSE). Then we generalize these equations to the case of N interacting solitons with almost equal velocities and widths. On the basis of this result we prove that the N MNSE-soliton train interaction (N>2) can be modeled by the completely integrable complex Toda chain (CTC). This is an argument in favor of universality of the complex Toda chain which was previously shown to model the soliton train interaction for nonlinear Schrodinger solitons. The integrability of the CTC is used to describe all possible dynamical regimes of the N-soliton trains which include asymptotically free propagation of all N solitons, N-soliton bound states, various mixed regimes, etc. It allows also to describe analytically the manifolds in the 4N-dimensional space of initial soliton parameters which are responsible for each of the regimes mentioned above. We compare the results of the CTC model with the numerical solutions of the MNSE for 2 and 3-soliton interactions and find a very good agreement.

description: When choosing among retail store formats, consumers face two alternatives: everyday-low-price (EDLP) stores that offer lower mean prices, with less variation over time, or promotion-based (HILO) stores that offer higher mean prices but more variation over time. In this study, we investigate a relationship between consumers’ risk preferences and their store-choice decisions. We use data from a two-stage, incentive-compatible experiment to measure subjects’ risk preferences and to examine how their attitudes toward risk influence their preferences for store price format.We find that retailers’ pricing strategies allow consumers with different risk attitudes to choose a particular store price format.

description: In randomized clinical trials to compare overdispersed count data between treatment groups, blinded sample size re-estimation (BSSR) is an effective approach to ensure power control even under possible misspecifications of the variance function on overdispersion specified at the design stage. Based on interim clinical trial data, the existing BSSR methods try to find a more appropriate value of the dispersion parameter for a “fixed” variance function specified at the design stage. In this article, we develop a new BSSR method that allows for modification of the variance function itself. Simulation studies demonstrated a stable power control of the proposed method. An application to a phase III clinical trial in chronic obstructive pulmonary disease also demonstrated effectiveness of the proposed method.

description: The Eu{+2} spins-7/2 in EuNi2As2 with the body-centered tetragonal ThCr2Si2 structure order antiferromagnetically below the Neel temperature TN =15 K into a helical antiferromagnetic (AFM) structure with the helix axis aligned along the tetragonal c axis and the Eu ordered moments aligned ferromagnetically within the ab plane as previously reported from neutron diffraction measurements [T. Jin, et al., Phys. Rev. B 99, 014425 (2019)]. Here we study the crystallographic, magnetic, thermal, and electronic transport properties of Bi-flux-grown single crystals using single-crystal x-ray diffraction, anisotropic magnetic susceptibility chi, isothermal magnetization M, heat capacity Cp, and electrical resistivity rho measurements versus applied magnetic field H and temperature T. Vacancies are found on the Ni sites corresponding to the composition EuNi{1.95}As2. The chi{ab}(T) data below TN are fitted well by molecular field theory (MFT), and the helix turn angle kd and the Eu-Eu Heisenberg exchange constants are extracted from the fit parameters. The kd value is in good agreement with the neutron-diffraction result. The magnetic contribution to the zero-field heat capacity below TN is also fitted by MFT. The isothermal in-plane magnetization Mab exhibits two metamagnetic transitions versus H, whereas Mc(T = 2 K) is nearly linear up to H =14 T, both behaviors being consistent with MFT. The Mc(H,T), rho(Hc,T), and Cp(Hc,T) data yielded a Hc-T phase diagram separating the AFM and paramagnetic phases in good agreement with MFT. Anisotropic chi(T) literature data for the ThCr2Si2-type helical antiferromagnet EuRh2As2 are also fitted well by MFT. A comparison is made between the crystallographic and magnetic properties of ThCr2Si2- type EuM2Pn2 compounds with M = Fe, Co, Ni, Cu, or Rh, and Pn = P or As, where only ferromagnetic and c-axis helical AFM structures are found.

description: We derive an explicit expression for the coupling constants of individual eigenstates of a closed billiard which is opened by attaching a waveguide. The Wigner time delay and the resonance positions resulting from the coupling constants are compared to an exact numerical calculation. Deviations can be attributed to evanescent modes in the waveguide and to the finite number of eigenstates taken into account. The influence of the shape of the billiard and of the boundary conditions at the mouth of the waveguide are also discussed. Finally we show that the mean value of the dimensionless coupling constants tends to the critical value when the eigenstates of the billiard follow random-matrix theory.

description: With the advancement of modern technologies, intensive longitudinal studies, where subjects get intensively measured in a relatively short period of time, have become popular in psychological and biomedical area. Challenges arise in better analyzing the rich amount of data and at the same time avoiding biased statistical inference introduced by potential informative missingness. Building upon previous studies by Lin et al. and Kapura et al., we aim to address the problem of informative missingness in the context of multivariate intensive longitudinal outcomes. In this article, we present a multivariate shared-parameter model, where the multivariate intensive longitudinal outcomes are modeled by a mixed-effects locations scale model and further linked with the corresponding missing mechanism by sharing the subject random effects. The proposed model is then estimated using Bayesian sampling approach. An adolescent mood study example is illustrated and results show that joint modeling of the mood assessments not only provide more accurate effect estimates, but also valuable information on the associations between multiple outcomes.

description: Due to their diverse nature, the faithful description of excited states within electronic structure theory methods remains one of the grand challenges of modern theoretical chemistry. Quantum Monte Carlo (QMC) methods have been applied very successfully to ground state properties but still remain generally less effective than other non-stochastic methods for electronically excited states. Nonetheless, we have recently reported accurate excitation energies for small organic molecules at the fixed-node diffusion Monte Carlo (FN-DMC) within a Jastrow-free QMC protocol relying on a deterministic and systematic construction of nodal surfaces using the selected configuration interaction (sCI) algorithm known as CIPSI (Configuration Interaction using a Perturbative Selection made Iteratively). Albeit highly accurate, these all-electron calculations are computationally expensive due to the presence of core electrons. One very popular approach to remove these chemically-inert electrons from the QMC simulation is to introduce pseudopotentials (also known as effective core potentials). Taking the water molecule as an example, we investigate the influence of Burkatzki-Filippi-Dolg (BFD) pseudopotentials and their associated basis sets on vertical excitation energies obtained with sCI and FN-DMC methods. Although these pseudopotentials are known to be relatively safe for ground state properties, we evidence that special care may be required if one strives for highly accurate vertical transition energies. Indeed, comparing all-electron and valence-only calculations, we show that using pseudopotentials with the associated basis sets can induce differences of the order of 0.05 eV on the excitation energies. Fortunately, a reasonable estimate of this shift can be estimated at the sCI level.

description: In thin-layer electrodeposition the dissipated electrical energy leads to a substantial heating of the ion solution. We measured the resulting temperature field by means of an infrared camera. The properties of the temperature field correspond closely with the development of the concentration field. In particular we find, that the thermal gradients at the electrodes act like a weak additional driving force to the convection rolls driven by concentration gradients.

description: We investigate the in-medium modification of pseudoscalar and vector mesons in a QCD motivated chiral quark model by solving the Dyson-Schwinger equations for quarks and mesons at finite temperature for a wide mass range of meson masses, from light (pi, rho) to open-charm (D, D*) states. At the chiral / deconfinement phase transition, the quark-antiquark bound states enter the continuum of unbound states and become broad resonances (the hadronic Mott effect). We calculate the in-medium cross sections for charmonium dissociation due to collisions with light hadrons in a chiral Lagrangian approach, and show that the D and D* meson spectral broadening lowers the threshold for charmonium dissociation by pi and rho meson impact. This leads to a step-like enhancement in the reaction rate. We suggest that this mechanism for enhanced charmonium dissociation may be the physical mechanism underlying the anomalous J/Psi suppression observed by NA50.

description: We present a micrometer scale, on-chip integrated, plasmonic enhanced graphene photodetector (GPD) for telecom wavelengths operating at zero dark current. The GPD is designed and optimized to directly generate a photovoltage and has an external responsivity~12.2V/W with a 3dB bandwidth~42GHz. We utilize Au split-gates with a$\sim$100nm gap to electrostatically create a p-n-junction and simultaneously guide a surface plasmon polariton gap-mode. This increases light-graphene interaction and optical absorption and results in an increased electronic temperature and steeper temperature gradient across the GPD channel. This paves the way to compact, on-chip integrated, power-efficient graphene based photodetectors for receivers in tele and datacom modules

description: We present new results on how the presence of stellar companions affects disk evolution based on a study of the 5-11 Myr old Upper Scorpius OB Association. Of the 50 G0-M3 Upper Sco members with disks in our sample, only seven host a stellar companion within 2" and brighter than K = 15, compared to 35 of 75 members without disks. This matches a trend seen in the 1-2 Myr old Taurus region, where systems with a stellar companion within 40 au have a lower fraction of infrared-identified disks than those without such companions, indicating shorter disk lifetimes in close multiple systems. However, the fractions of disk systems with a stellar companion within 40 au match in Upper Sco and Taurus. Additionally, we see no difference in the millimeter brightnesses of disks in Upper Sco systems with and without companions, in contrast to Taurus where systems with a companion within 300 au are significantly fainter than wider and single systems. These results suggest that the effects of stellar companions on disk lifetimes occur within the first 1-2 Myr of disk evolution, after which companions play little further role. By contrast, disks around single stars lose the millimeter-sized dust grains in their outer regions between ages of 1-2 Myr and 5-11 Myr. The end result of small dust disk sizes and faint millimeter luminosities is the same whether the disk has been truncated by a companion or has evolved through internal processes.

description: Doctoral programs in agricultural economics have long been the primary source of agribusiness management faculty in the United States. One measure of doctoral training is the choice of a dissertation topic. Presumably, doctoral students will choose to work with faculty that have expertise in their area of interest. Thus, one measure of doctoral programs that have expertise in agribusiness management is the choice of dissertation research by graduate students. In this paper, we look at dissertation topics over time. In particular, we segment dissertation topics into 14 different subject categories and compare these over the 1951 to 2002 time period. Three categories are likely to be highly correlated with whether a department has expertise in doctoral training of agribusiness management faculty. These categories are agribusiness management, food business, and industrial organization. Agribusiness management, food business, and industrial organization represented only 6.6 percent of all agricultural economics dissertations over the 1951 to 2002 time period. We agree with Peter Barry who suggests that agribusiness management research has begun to mature and that a bright future exists for such research.

description: We consider the two-dimensional (2D) flow in a flat free-slip surface that bounds a three-dimensional (3D) volume in which the flow is turbulent. The equations of motion for the two-dimensional flow in the surface are neither compressible nor incompressible but strongly influenced by the 3D flow underneath the surface. The velocity correlation functions in the 2D surface and in the 3D volume scale with the same exponents. In the viscous subrange the amplitudes are the same, but in the inertial subrange the 2D one is reduced to 2/3 of the 3D amplitude. The surface flow is more strongly intermittent than the 3D volume flow. Geometric scaling theory is used to derive a relation between the scaling of the velocity field and the density fluctuations of a passive scalar advected on the surface.

Lorenz-like systems and classical dynamical equations with memory forcing: a new point of view for singling out the origin of chaos

description: A novel view for the emergence of chaos in Lorenz-like systems is presented. For such purpose, the Lorenz problem is reformulated in a classical mechanical form and it turns out to be equivalent to the problem of a damped and forced one dimensional motion of a particle in a two-well potential, with a forcing term depending on the ``memory'' of the particle past motion. The dynamics of the original Lorenz system in the new particle phase space can then be rewritten in terms of an one-dimensional first-exit-time problem. The emergence of chaos turns out to be due to the discontinuous solutions of the transcendental equation ruling the time for the particle to cross the intermediate potential wall. The whole problem is tackled analytically deriving a piecewise linearized Lorenz-like system which preserves all the essential properties of the original model.

description: We found 19 masters and doctoral courses in agribusiness management being taught within the 66 agricultural economics programs that have graduate programs. Four of the courses have not been taught since 2001, three are cross-listed with an undergraduate course by the same name, and 10 of the courses are taught annually. The most common textbook used was Besanko et al.’s Economics of Strategy, which was used in eight courses. There was a variety of subjects taught in the courses but industry analysis, firm analysis, and financial concepts appeared to be the most common. The emphasis on written and oral communication skills is greater in these courses than most other courses taught at the graduate level. University of Missouri and Purdue University have separate courses for masters and doctoral students. Michigan State University offers a graduate certificate in agribusiness management for graduate students in other disciplines while University of Missouri has a unique curriculum built around organizational economics.

description: Eighty-four specimens collected from 13 populations from Malaysia, Thailand, and Vietnam were analysed, revealing 21 putative haplotypes with overall estimated haplotype and nucleotide diversities of 0.79 and 0.0079, respectively. High levels of diversity and an absence of founder effects were observed among populations in peninsular Malaysia. In contrast, populations from Sarawak exhibited low genetic diversity, which is a typical sign of colonies introduced from a single source. Historical translocation of Trichopodus pectoralis from Thailand to Malaysia, as well as to the Philippines, Indonesia, and Myanmar was apparent. Historical introduction of T. pectoralis from Vietnam was also detected in peninsular Malaysia.

description: At a boundary between two transparent, linear, isotropic, homogeneous materials, derivations of the electromagnetic boundary conditions and the Fresnel relations typically proceed from the Minkowski {E,B,D,H} representation of the macroscopic Maxwell equations. However, equations of motion for macroscopic fields in a transparent linear medium can be written using Ampere {E,B}, Chu {E,H}, Lorentz, Minkowski, Peierls, Einstein-Laub, and other formulations of continuum electrodynamics. We present a representation-independent derivation of electromagnetic boundary conditions and Fresnel relations for the propagation of monochromatic radiation through a piecewise-homogeneous, transparent, linear, magneto-dielectric medium. The electromagnetic boundary conditions and the Fresnel relations are derived from energy conservation coupled with the application of Stokes's theorem to the wave equation. Our representation-independent formalism guarantees the general applicability of the Fresnel relations. Specifically, the new derivation is necessary so that a valid derivation of the Fresnel equations exists for alternative, non-Minkowski formulations of the macroscopic Maxwell field equations.

description: An introductory course in agribusiness management is the third most required course in agricultural economics programs. It is also one of the most widely taught after agricultural marketing and agricultural finance. Advanced agribusiness management is often a course in strategy and was not being taught in agricultural economics programs in 1985. Many of the instructors for this class have been hired in recent years. It is no surprise why case research has become more popular in recent years given its importance for use in teaching and integrating concepts in strategy courses. The number of food business courses remains small but is concentrated in departments that have a history of doctoral research in this subject. Many of these programs teach agribusiness marketing and retail or wholesale marketing.

description: A wide range of engineering applications uses optimisation techniques as part of their solution process. The researcher uses specialized software that implements well-known optimisation techniques to solve his problem. However, when it comes to develop original optimisation techniques that fit a particular problem the researcher has no option but to implement his own new method from scratch. This leads to large development times and error prone code that, in general, will not be reused for any other application. In this work, we present a novel methodology that simplifies, fasten and improves the development process of scientific software. This methodology guide us on the identification of design patterns. The application of this methodology generates reusable, flexible and high quality scientific software. Furthermore, the produced software becomes a documented tool to transfer the knowledge on the development process of scientific software. We apply this methodology for the design of an optimisation framework implementing Newton's type methods which can be used as a fast prototyping tool of new optimisation techniques based on Newton's type methods. The abstraction, reusability and flexibility of the developed framework is measured by means of Martin's metric. The results indicate that the developed software is highly reusable.

description: Suppression of prairie fires enabled Eastern Red Cedar (ERC) to invade and thrive on more than 12 million infested acres previously dominated by native grasses. Feedstock procurement for a biorefinery designed to use ERC biomass, would be unique relative to energy crop production systems such as switchgrass that can be expected to harvest feedstock produced on the same unit of land each year. Density of ERC is heterogeneous. After cutting, ERC does not regrow and after ERC is removed landowners could be expected to take measures such as prescribed fire to control it. A mixed integer mathematical programming model is constructed to determine the cost to obtain the rights to harvest, harvest, and deliver a specified quantity of ERC biomass each year, for a period of 20 years, to a biorefinery location. The optimal strategy depends critically on several assumptions including the proportion of ERC biomass under contract enabling ERC harvest once during the 20 years; ERC growth rate; ERC density; discount rate; harvest and transportation cost; and quantity of biomass required per day. Optimal harvest strategy, optimal biorefinery location, and maximum daily biorefinery capacity, are sensitive to tree density and the proportion of ERC biomass in the region from which ERC can be removed. The expected cost of delivered biomass ranges from $41 to $92 per ton depending on the assumption of proportion of ERC biomass under contract, quantity of biomass required at the biorefinery, harvest cost, growth rate of unharvested trees under contract, and discount rate.

description: In recent years, there has been growing interest in using Precipitable Water Vapor (PWV) derived from Global Positioning System (GPS) signal delays to predict rainfall. However, the occurrence of rainfall is dependent on a myriad of atmospheric parameters. This paper proposes a systematic approach to analyze various parameters that affect precipitation in the atmosphere. Different ground-based weather features like Temperature, Relative Humidity, Dew Point, Solar Radiation, PWV along with Seasonal and Diurnal variables are identified, and a detailed feature correlation study is presented. While all features play a significant role in rainfall classification, only a few of them, such as PWV, Solar Radiation, Seasonal and Diurnal features, stand out for rainfall prediction. Based on these findings, an optimum set of features are used in a data-driven machine learning algorithm for rainfall prediction. The experimental evaluation using a four-year (2012-2015) database shows a true detection rate of 80.4%, a false alarm rate of 20.3%, and an overall accuracy of 79.6%. Compared to the existing literature, our method significantly reduces the false alarm rates.

description: In this paper we probe the Sivers asymmetries through $\rm J/ψ$ photoproduction in $\rm p^\uparrow p$ collision within the non-relativistic QCD framework, based on color octet model and the Transverse Momentum Dependent Parton Distributions (TMDs). Both the DGLAP evolution and the TMD evolution are included. The intensity and the sign of the Sivers asymmetry is strongly related on evolution model used to investigate the Gluon Sivers Function (GSF). A sizable asymmetry is obtained as a function of the rapidity, $\rm log{(x_γ)}$ or $\rm log{(x_{g})}$ dependence using a recent parametrization of GSF at the RHIC and AFTER@LHC experiments with the LHC planned forward detector acceptances.

description: Sorrel, Hibiscus sabdariffa, has autogamous flowers that self-pollinate prior to flower opening resulting in inbred varieties. Cross pollination of inbred plants normally results in hybrid with vigor that out-perform both parents. Two varieties of red sorrel, 'TTB', which is deep crimson and open, and a 'KDN', which is day neutral and red, were use as parents. 'TTB' was late flowering with a crimson fruit and 'KDN' was day-neutral with red fruit. The objective was to study two parental sorrel lines and the F1 and F3 progeny to evaluate plant vigor for production, floral initiation, fruit color and shape. Selection of plants from the F2 population were used to obtain seed for the F3 progeny. Plant vigor was determined by measuring plant height and number of branches at two week intervals as well as recording when floral buds became visible. Though the F1 population of 'TTB' χ 'KDN' had a trend of being taller than the parents, it wasn't significant for plant height and branch development. The F3 populations were significantly taller than the F1 and parent varieties. The F1 and F3 'TTB'x'KDN' plants initiated flowers at the same time as 'TTB' which was two weeks later than 'KDN'. However, the F3 line of 'KDN'x'TTB' initiated flowers at the same time as 'KDN' indicating a new day neutral variety. Hybrid vigor can be obtained from specific controlled crosses in sorrel. The day neutral characteristic can be recovered in F3 population where 'KDN' was the female parent. This research was funded through USDA-NIFA- Insular Tropical Grant funds and USDA-NIFA-SCBG from the VI Department of Agriculture.

description: We consider existence and stability properties of nonlinear spatially periodic or quasiperiodic standing waves (SWs) in one-dimensional lattices of coupled anharmonic oscillators. Specifically, we consider Klein-Gordon (KG) chains with either soft (e.g., Morse) or hard (e.g., quartic) on-site potentials, as well as discrete nonlinear Schroedinger (DNLS) chains approximating the small-amplitude dynamics of KG chains with weak inter-site coupling. The SWs are constructed as exact time-periodic multibreather solutions from the anticontinuous limit of uncoupled oscillators. In the validity regime of the DNLS approximation these solutions can be continued into the linear phonon band, where they merge into standard harmonic SWs. For SWs with incommensurate wave vectors, this continuation is associated with an inverse transition by breaking of analyticity. When the DNLS approximation is not valid, the continuation may be interrupted by bifurcations associated with resonances with higher harmonics of the SW. Concerning the stability, we identify one class of SWs which are always linearly stable close to the anticontinuous limit. However, approaching the linear limit all SWs with nontrivial wave vectors become unstable through oscillatory instabilities, persisting for arbitrarily small amplitudes in infinite lattices. Investigating the dynamics resulting from these instabilities, we find two qualitatively different regimes for wave vectors smaller than or larger than pi/2, respectively. In one regime persisting breathers are found, while in the other regime the system rapidly thermalizes.
