Subjects: subject: Chaotic Dynamics (nlin.CD)
subject: FOS: Physical sciences

description: To a unitary matrix U we associate a doubly stochastic matrix M by taking the modulus squared of each element of U. To study the connection between onset of quantum chaos on graphs and ergodicity of the underlying Markov chain, specified by M, we study the limiting distribution of the spectral gap of M when U is taken from the Circular Unitary Ensemble and the dimension N of U is taken to infinity. We prove that the limiting distribution is degenerate: the gap tends to its maximal value 1. The shape of the gap distribution for finite N is also discussed.

description: We present new methodology and a case study in use of a class of Bayesian predictive synthesis (BPS) models for multivariate time series forecasting. This extends the foundational BPS framework to the multivariate setting, with detailed application in the topical and challenging context of multistep macroeconomic forecasting in a monetary policy setting. BPS evaluates—sequentially and adaptively over time—varying forecast biases and facets of miscalibration of individual forecast densities for multiple time series, and—critically—their time-varying inter-dependencies. We define BPS methodology for a new class of dynamic multivariate latent factor models implied by BPS theory. Structured dynamic latent factor BPS is here motivated by the application context—sequential forecasting of multiple U.S. macroeconomic time series with forecasts generated from several traditional econometric time series models. The case study highlights the potential of BPS to improve of forecasts of multiple series at multiple forecast horizons, and its use in learning dynamic relationships among forecasting models or agents.

description: After 28 years from the conception of the pyramid WFS several new kind of devices able to convert wavefront shape into some sort of different illumination on a detector have been conceived. While, suspending momentarily any kind of modesty, I claim credit for being among the few that contributed to show at the time that there could be much more than just a lenslet array I continued -with alternating successes- to conceive other types of such devices. I revise here only the one that I conceived on my own and, sometime stretching up and down the definition of novel concept I piled up 28 different WFSs, one per year from the pivotal introduction of the most successful it took to me to write down on paper.

description: The existing calculations of the nuclear matrix elements of the neutrinoless double $β$-decay differ by about a factor three. This uncertainty prevents quantitative interpretation of the results of experiments searching for this process. We suggest here that the observation of the neutrinoless double $β$-decay of {\em several} nuclei could allow to test calculations of the nuclear matrix elements through the comparison of the ratios of the calculated lifetimes with experimental data. It is shown that the ratio of the lifetimes is very sensitive to different models.

description: This study measures the impact of corn-based ethanol production in the United States on land use in other countries, or indirect land use. Indirect land use is a change from non-cropland to cropland (e.g. deforestation) that may occur in response to increasing scarcity of cropland. As farmers worldwide respond to higher crop prices in order to maintain the global food supply and demand balance, pristine lands are cleared and converted to new cropland to replace the crops for feed and food that were diverted elsewhere to biofuel production. The results show that increasing ethanol production in the US has a positive and significant relation to U.S corn price. However, U.S. corn price does not have a significant impact on changes in corn acreage in Brazil and other countries such as Canada, Japan and China. Although many authors have hypothesized that increased ethanol production in the U.S. will increase corn prices, which will result in increased change in land use in other countries, these results suggest that the effect is minimal at best. This is important because although production of ethanol for fuel is often criticized for negatively impacting the environment because of indirect land use, this study was unable to prove the existence of indirect land use.

description: This study was conducted to prepare new complexes and their metal-based nanodrugs in order to reduce the growth of human carcinoma cell lines. For this purpose, an extensive study was performed. First, the mixed-chelate Cu(II) complexes Casiopeínas® ([Cu(TTA)(phen)(C1O4)] 1 and [Cu(TTA)(phen)(N3)Cu(TTA)(phen)H2O] (C1O4)·H2O 2 (TTA = 4,4,4-trifluoro-1-(2-furyl)-1,3-butanedione) were synthesized and characterized by X-ray, FT-IR, UV–Vis spectroscopy, conductivity measurements, diffuse reflection spectroscopy and elemental analysis studies. Complexes 1 and 2 exhibited tetragonal pyramidal geometry. In the following, nanoparticles (NPs) of complexes 3 and 4 with the average size of 81 and 33 nm, respectively, were prepared by an ultrasonic process. Scanning Electron Microscope (SEM) images of samples 3 and 4 showed that the morphologies of the obtained materials are rod and sphere, respectively. Furthermore, the cytotoxic activity of complexes and nanoparticles was investigated against MKN-45 cell lines. The cell proliferation was inhibited for all compounds and nanocompounds in a dose-dependent manner 1 > 2 > 3 > 4 on MKN-45 cells. Finally, docking calculations were performed to describe the mode of binding to DNA of these complexes. Docking simulations suggested that the compounds bind in the minor groove and preferentially bind to A-T base pair regions. Both complexes also interacted with DNA through one hydrogen-bond.
Surface Quasigeostrophic Turbulence : The Study of an Active Scalar

description: We study the statistical and geometrical properties of the potential temperature (PT) field in the Surface Quasigeostrophic (SQG) system of equations. In addition to extracting information in a global sense via tools such as the power spectrum, the g-beta spectrum and the structure functions we explore the local nature of the PT field by means of the wavelet transform method. The primary indication is that an initially smooth PT field becomes rough (within specified scales), though in a qualitatively sparse fashion. Similarly, initially 1D iso-PT contours (i.e., PT level sets) are seen to acquire a fractal nature. Moreover, the dimensions of the iso-PT contours satisfy existing analytical bounds. The expectation that the roughness will manifest itself in the singular nature of the gradient fields is confirmed via the multifractal nature of the dissipation field. Following earlier work on the subject, the singular and oscillatory nature of the gradient field is investigated by examining the scaling of a probability measure and a sign singular measure respectively. A physically motivated derivation of the relations between the variety of scaling exponents is presented, the aim being to bring out some of the underlying assumptions which seem to have gone unnoticed in previous presentations. Apart from concentrating on specific properties of the SQG system, a broader theme of the paper is a comparison of the diagnostic inertial range properties of the SQG system with both the 2D and 3D Euler equations.

description: We analyze the unitary time evolution of a conduction electron, described by a two-level system, interacting with two-level systems (spins) through a spin-spin interaction and prove that coherent spin states of the conduction electron are obtained in the strong coupling regime, when the number of the spins is taken to be, formally, infinitely large (thermodynamic limit). This model describes a spin interacting with a spin-bath in a strong coupling regime and gives a dephasing time at zero temperature that agrees with the recent experimental results for quantum dots. Dephasing is proved to occur as the conduction electron oscillates between the two states with frequency going to infinity in the thermodynamic limit, that is, increasing the number of spins. Then, it is shown that the only meaning that can be attached to such oscillations with infinite frequency is by an average in time, eliminating the off-diagonal terms of the density matrix. This model is in agreement with a recent proposal of appearance of classical states in quantum mechanics due to the large number of components of a quantum system, if properly prepared for the states of each component part. The strong coupling study of the model is accomplished through the principle of duality as recently introduced in perturbation theory [M.Frasca, Phys. Rev. A {\bf 58}, 3439 (1998)].

description: The reduction in the availability of irrigation water and the increase in pumping costs resulting from the decline in the Ogallala Aquifer make good management decisions more critical for the survival of the farm firm and the success of the agricultural sector in the Texas Panhandle. Response functions for irrigation and percentage potential evapotranspiration (PET) in the production of grain sorghum are estimated. The response functions are transferred into value product functions and combined with an irrigation energy cost function to determine the profit maximizing irrigation strategy. Three management decision variables; total water available, the level of irrigation and the water to meet crop ET requirements are evaluated. Grain sorghum yield, natural precipitation, irrigation, soil moisture content, potential evapotranspiration, and percent potential evapotranspiration (PET) data, collected over the period from 1998 through 2007 by commercial producers participating in the AgriPartners program are used to estimate the response functions. Results indicate that the optimum level of irrigation increases as the price of sorghum increases and decreases as the price of natural gas increases.

description: Dynamical tunneling between symmetry related invariant tori is studied in the near-integrable regime. Using the kicked Harper model as an illustration, we show that the exponential decay of the wave functions in the classically forbidden region is modified due to coupling processes that are mediated by classical resonances. This mechanism leads to a substantial deviation of the splitting between quasi-degenerate eigenvalues from the purely exponential decrease with 1 / hbar obtained for the integrable system. A simple semiclassical framework, which takes into account the effect of the resonance substructure on the KAM tori, allows to quantitatively reproduce the behavior of the eigenvalue splittings.

Master equation approach to the conjugate pairing rule of Lyapunov spectra for many-particle thermostatted systems

description: The master equation approach to Lyapunov spectra for many-particle systems is applied to non-equilibrium thermostatted systems to discuss the conjugate pairing rule. We consider iso-kinetic thermostatted systems with a shear flow sustained by an external restriction, in which particle interactions are expressed as a Gaussian white randomness. Positive Lyapunov exponents are calculated by using the Fokker-Planck equation to describe the tangent vector dynamics. We introduce another Fokker-Planck equation to describe the time-reversed tangent vector dynamics, which allows us to calculate the negative Lyapunov exponents. Using the Lyapunov exponents provided by these two Fokker-Planck equations we show the conjugate pairing rule is satisfied for thermostatted systems with a shear flow in the thermodynamic limit. We also give an explicit form to connect the Lyapunov exponents with the time-correlation of the interaction matrix in a thermostatted system with a color field.

We based our study on $^{12}$CO(2-1), $^{13}$CO(2-1), and C$^{18}$O(2-1) data obtained with the APEX telescope, molecular data of high density tracers from the MALT90 survey and IR images from Spitzer, Herschel and ATLASGAL. The study reveals two clumps at -44 km/s towards the IRDC, with densities of > 10$^4$ cm$^{-3}$ , typical of IRDCs, while high density tracers show H$_2$ densities > 10$^5$ . FIR images reveals the presence of cold dust linked to the molecular clumps and EGOs. A comparison of spectra of the optically thin and optically thick molecular lines towards the EGOs suggests the existence of infall and outflow motions.

A Cosmological basis for E=mc^2

Year: 2019
Subjects: subject: General Physics (physics.gen-ph)

description: The Universe has a gravitational horizon with a radius R_h=c/H coincident with that of the Hubble sphere. This surface separates null geodesics approaching us from those receding, and as free-falling observers within the Friedmann-Lemaitre-Robertson-Walker spacetime, we see it retreating at proper speed c, giving rise to the eponymously named cosmological model R_h=ct. As of today, this cosmology has passed over 25 observational tests, often better than LCDM. The gravitational/Hubble radius R_h therefore appears to be highly relevant to cosmological theory, and in this paper we begin to explore its impact on fundamental physics. We calculate the binding energy of a mass m within the horizon and demonstrate that it is equal to mc^2. This energy is stored when the particle is at rest near the observer, transitioning to a purely kinetic form equal to the particle's escape energy when it approaches R_h. In other words, a particle's gravitational coupling to that portion of the Universe with which it is causally connected appears to be the origin of rest-mass energy.

description: This study estimates the carbon footprint of a Henderson County, Kentucky grain farmer under different production strategies; traditional farming and precision agriculture technologies. Four constrained optimization, whole farm analysis models were formulated under no-till conditions. One of the models was optimized without utilizing any precision agriculture techniques and was used as a base model to compare the other three models which incorporated precision agriculture technologies (PAT). The three technologies investigated include sub-meter auto-steer, RTK auto-steer and automatic section control (ASC). These models are used to analyze the different production systems to determine if said technologies increase expected net returns and enhance the carbon input:output ratio. Given the levels of anthropogenic greenhouse gases released by the agricultural sector, quantifying the potential reduction in these gases due to the adoption of PAT is essential in seeing exactly how PAT can alter the impacts to the environment. The results show that all precision agriculture techniques produce a Pareto improvement over the base model. Specifically, automatic section control gave the greatest improvement with a mean net return that was 0.59% over the base. RTK provided the most significant enhancement in the carbon ratio with an improvement of 2.42% over the base model. All of these improvements over the base scenario can to the adoption of precision agriculture technology.

description: Biosorption technology has been acknowledged as one of the most successful treatment approaches for colored industrial effluents. The problems such as its high manufacturing cost and poor regeneration capability in the use of activated carbon as a biosorbent have prompted the environmental scientists to develop alternative biosorbent materials. In this context, as a sustainable green generation alternative biosorbent source, the discarded seed biomass from pepper (Capsicum annuum L.) processing industry was explored for the biotreatment of colored aqueous effluents in this study. To test the wastewater cleaning ability of biosorbent, Basic red 46 was selected as a typical model synthetic dye. Taguchi DoE methodology was employed to study the effect of important operational parameters, contact time, pH and synthetic dye concentration, on the biosorption process and to develop a mathematical model for the estimation of biosorption potential of biosorbent. The percentage contribution of each of these process variables on the dye biosorption was found to be 19.31%, 41.39%, and 38.74%, respectively. The biosorption capacity under the optimum environmental conditions, contact time of 360 min, pH of 8 and dye concentration of 30 mg L−1, was estimated to be 92.878 mg g−1 (R2: 99.45). This value was very close to the experimentally obtained dye removal performance value (92.095 mg g−1). These findings indicated the high ability of Taguchi DoE technique in the optimization and simulation of dye biosorption system. The kinetic and equilibrium modeling studies showed that the pseudo-second-order and Langmuir models were the best models for the elucidation of dye removal behavior of biosorbent. The thermodynamic studies displayed that the dye biosorption was a feasible, spontaneous and exothermic process. This parametric and phenomenological survey revealed that the discarded pepper seed biomass can be introduced as a potential and efficient biosorbent for the bioremediation of colored industrial effluents.

description: In order to study the location of circumnuclear rings (CNR) and their possible relation with the inner Lindblad resonances (ILR), we investigate a sample of spiral galaxies. For this purpose, we have obtained and analyzed medium resolution spectra of 5 spiral galaxies in the range 6200 Å\ to 6900 Å.\, Through the H$α$ emission line, we constructed the radial velocity curves, and then the rotation curves. By fitting them, considering two or three components of an axisymetric Miyamoto$-$Nagai gravitational potential, we constructed the angular velocity and Lindblad curves. In addition, we determined the CNR radius by using the 2D spectra and generating the H$α$ spatial emission radial profiles. We determined the position of the resonances and we calculated the angular velocity pattern, which are in the range of 26 $-$ 47 km s$^{-1}$ kpc$^{-1}$ for the galaxies of the sample. According to our results, the CNRs are located between the inner ILR (iILR) and the outer ILR (oILR), or between the center of the galaxy and the ILR, when the object has only one of such resonance; in agreement with previous results. In addition, we calculated the dimensionless parameter defined as $\mathcal{R}=$ R$_{CR}$ / R$_{bar}$, being in the range 1.1 $-$ 1.6, in agreement with previous results found in the literature.

description: The objective of this study is to estimate the impact of natural amenity on farmland values in the contiguous United States using a quantile regression approach and data from the 2006, 2007, and 2008 Agricultural Resource Management Surveys. The contribution of this study is three-fold. First, we explicitly include variables representing natural amenity and soil characteristics of farmland. Second, we employ a quantile regression approach to examine potentially heterogeneous impacts of natural amenity and soil characteristics at different quantiles of farmland values. Third, we utilized data from a nationwide survey of farm household to examine findings in studies using regional data are consistent at a national scale. Our quantile regression analysis offers some insightful results. Natural amenity is positively correlated with farmland values and its impact is often more pronounced at a higher price range of farmland.

description: The sustainable integration of Learning Analytics (complying with the FAIR principles) in an eXtended Reality application is complex. Following an iterative process, a framework and ecosystem were developed to overcome this and provide guidance for producing research software with reproducibility, reusability, and accuracy in mind. Using the solution, the requirements for new projects have been seamlessly expanded. We observed seven Computer Science students while integrating Learning Analytics into a Virtual Reality application to explore the current state of the framework and ecosystem regarding productivity, workflow, usability, functionality, and challenges. This paper presents and reflects the method and results of our observation study.

description: Die wachsende Bedeutung von Data Literacy sowie Kompetenzen im Umgang mit Künstlicher Intelligenz (KI) spiegelt sich zunehmend auch im Bildungswesen wider. Dies führt zu einem wachsenden Bedarf an Aus- und Weiterbildung über KI. Bislang mangelt es dabei noch an
koordinierten Herangehensweisen und einem strukturierten Austausch, um Ergebnisse verschiedener Initiativen und individueller Bemühungen zu integrieren und Erkenntnisse wechselseitig nutzbar zu machen. Der Workshop zielte darauf ab, Forschende, Lehrende sowie Akteur:innen aus der Praxis, die sich mit Aus- und Weiterbildung zu KI beschäftigen, zusammenzubringen und den Wissenstransfer zu unterstützen. Der Workshop fokussierte dabei auf Ansätze zur empirischen Analyse von Aus- und Weiterbildung zu KI sowie den Austausch von Erfahrungen aus bestehenden Initiativen und Projekten, beispielsweise zur curricularen Integration oder praxisorientierten Lehre. Dabei wurde deutlich, dass eine stärkere Vernetzung der Initiativen und Forschungsprojekte im Kontext von KI und Bildung erstrebenswert und Austauschformate nötig sind. Weiterhin zeigte sich eine große
Bandbreite an Themen und Erfahrungsständen in der Community. Es scheint empfehlenswert, weitere Austauschformate zu planen und Synthese von Erkenntnissen von Forschung und Praxis über ein dezidiertes Kompetenzzentrum voranzutreiben.
Transverse Momentum Spectra of Pions in Particle and Nuclear Collisions and Some Ratio-Behaviours: Towards A Combinational Approach

description: The nature of transverse momentum dependence of the inclusive cross-sections for secondary pions produced in high energy hadronic($PP$), hadronuclear($PA$) and nuclear($AA$) collisions has here been exhaustively investigated for a varied range of interactions in a unified way with the help of a master formula. This formula evolved from a new combination of the basic Hagedorn's model for particle(pion) production in PP scattering at ISR range of energies, a phenomenological approach proposed by Peitzmann for converting the results of $NN(PP)$ reactions to those for either $PA$ or $AA$ collisions, and a specific form of parametrization for mass number-dependence of the nuclear cross sections. This grand combination of models(GCM) is then applied to analyse the assorted extensive data on various high energy collisions. The nature of qualitative agreement between measurements and calculations on both the inclusive cross-sections for production of pions, and some ratios of them as well, is quite satisfactory. The modest successes that we achieve here in dealing with the massive data-sets are somewhat encouraging in view of the diversity of the reactions and the very wide range of interaction energies.
