description: Arkansas rice production is highly dependent on energy related inputs such as water and nitrogen. This analysis uses Data Envelopment analysis (DEA) to calculate non-radial technical efficiency scores and quantifies input overuse for rice fields enrolled in the University of Arkansas, Rice Research Verification Program (RRVP), with special emphasis placed on estimation of water and nitrogen input overuse. The results reveal technical inefficiency exists in both water and nitrogen application, but other inputs may play more of a role in the overall technical inefficiency on rice fields. Average estimated overuse of water and nitrogen was 27.9% and 14.7%, respectively.

description: Magnetic fields force ballistic electrons injected from a narrow contact to move along skipping orbits and form caustics. This leads to pronounced resistance peaks at nearby voltage probes as electrons are effectively focused inside them, a phenomenon known as magnetic focusing. This can be used not only for the demonstration of ballistic transport but also to study the electronic structure of metals. Here we use magnetic focusing to probe narrow bands in graphene bilayers twisted at 2 degrees. Their minibands are found to support long-range ballistic transport limited at low temperatures by intrinsic electron-electron scattering. A voltage bias between the layers causes strong valley splitting and allows selective focusing for different valleys, which is of interest for using this degree of freedom in frequently-discussed valleytronics.

description: Two-dimensional (2D) materials with intrinsic ferromagnetism provide unique opportunity to engineer new functionalities in nano-spintronics. One such material is CrI$_3$, showing long-range magnetic order in monolayer with the Curie temperature ($T_c$) of 45 K. Here we study detailed evolution of magnetic transition and magnetic critical properties in response to systematic reduction in crystal thickness down to 50 nm. Bulk $T_c$ of 61 K is gradually suppressed to 57 K, however, the satellite transition at $T^*$ = 45 K is observed layer-independent at fixed magnetic field of 1 kOe. The origin of $T^*$ is proposed to be a crossover from pinning to depinning of magnetic domain walls. The reduction of thickness facilitates a field-driven metamagnetic transition around 20 kOe with out-of-plane field, in contrast to the continuous changes with in-plane field. The critical analysis around $T_c$ elucidates the mean-field type interactions in microscale-thick CrI$_3$.

description: This paper is concerned with the trends of stress fluctuations in dry granular materials as functions of the sample size D and of the grain diameter d. Results are obtained in the plateau regime of large axial deformation, during axi-symmetric uni-axial compression. Two cases have to be distinguished depending on whether the material generates or does not generate stick-slip. When no stick-slip is generated (Fig.1), it is found that the relative stress fluctuations dq/q of the deviatoric stress q scales linearly with the ratio d/D >. The coefficient A relating dq/q and d/D ranges from 1 to 3 about, depending on the grain size d; this is probably due to the effect of the piston roughness. This result is compatible with a contact force network with a random force distribution and a short range correlation length L,i.e. L<3d; this leads to estimate the representative elementary volume REV to contain few grains (from 1 to 30) as it has been defended already in [1]. We turn now to cases exhibiting stick-slip (Fig. 2). It has been shown in [2] that the distribution of delays between events is rather "exponential" when the sample is small, and Gaussian-like when the sample is larger. The cross-over between the random to quasi periodic regime occurs for a typical sample which contains 10 000 000 grains [2]. In this paper we show an analogy between the statistics of stick-slip amplitude Dq/q and the seismicity of the Los Angeles area during 1979-1997 period [3]. Similarity of the two trends is quite surprising. The seismicity has been cut off at Magnitude M=3.5. These results have to be handled with care since similarity may be fortuitous.

description: Agricultural wastes have, of recent, been utilized as useful coarse aggregates in concrete to reduce/eliminate harmful effects on the environment and the hazard to the residents in the locations, where they are deposited as wastes. This study focused on the replacement of conventional aggregate with palm kernel shell (PKS) in the production of palm kernel shell concrete (PKSC) kerb. PKS was characterized as coarse aggregate in concrete production. Ten (10) Nos. 150x150x150 mm cubes of PKSC were produced, cured and crushed after 7 and 28 days (Five cubes on each day) to determine the compressive strength in accordance with BS 1881 (1986). Thirty (30) Nos. of PKSC kerbs of dimension 0.5x0.35x0.10 m were then produced based on the 28th compressive strength of the cubes produced. Results sieve analysis showed that palm kernel shell is well graded and a good replacement for conventional coarse aggregate in concrete. Also, the physical properties of palm kernel shell fall within the specified value for lightweight aggregate,
confirming PKS as a lightweight aggregate. The density and compressive strength after 28-day curing were 1583.80 kg/m3 and 17.59 N/mm2, respectively. These values are within the specified values 1700-2050 kg/m3 and 15-25 N/mm2, correspondingly for lightweight concrete, further confirming PKS as a lightweight aggregate. Palm kernel shell concrete is, therefore suitable for the production kerbs for application in pavement works

description: Fourier transform infrared (FTIR) spectroscopy was used to study two kinds of broad beans with white and green cotyledons respectively. The results show that the infrared spectra of the two kinds of broad beans are similar and mainly made up of the absorption bands of protein, and polysaccharides. The second derivative infrared spectra amplified the differences and revealed that there were some obvious differences in the range of 1 800-700cm-1 and 1 200-700cm-1. Hierarchical cluster analysis (HCA) were used for the discrimination of the two kinds broad beans based on the second derivative spectral data in the region of 1 611-1 100cm-1, and yielded 88.9 % accuracy. The spectra in the range from 1700 to 1600cm-1 were used to perform Fourier self-deconvolution and curve fitting, which obtained nine peaks. The ratios of relative areas of the bands at α-helix, β-sheet, β-turn and the unordered structure of protein in white beans were 67.71%, 35.6%, 35.6% and 21.09% respectively, while the ratios in green beans were 8.02%, 31.59%, 37.12% and 23.27% respectively. The results indicate that the secondary structure of protein was different in the two kinds of broad beans.

description: Ab initio-calculated ideal strength and toughness describe the upper limits for mechanical properties attainable in real systems and can, therefore, be used in selection criteria for materials design. We employ density-functional ab initio molecular dynamics (AIMD) to investigate the mechanical properties of defect-free rocksalt-structure (B1) TiN and B1 Ti1-xAlxN (x = 0.25, 0.5, 0.75) solid solutions subject to [001], [110], and [111] tensile deformation at room temperature. We determine the alloys' ideal strength and toughness, elastic responses, and ability to plastically deform up to fracture as a function of the Al content. Overall, TiN exhibits greater ideal moduli of resilience and tensile strengths than TiAlN solid solutions. Nevertheless, AIMD modelingshows that, irrespective of the strain direction, the binary compound systematically fractures by brittle cleavage at its yield point. The simulations also indicate that Ti0.5Al0.5N and Ti0.25Al0.75N solid solutions are inherently more resistant to fracture and possess much greater toughness than TiN, due to the activation of local structural transformations (primarily of B1 -> wurtzite type) beyond the elastic-response regime. In sharp contrast, TiAlN alloys with 25% Al exhibit similar brittleness as TiN. The results of this work are examples of the limitations of elasticity-based criteria for prediction of strength, brittleness, ductility, and toughness in materials able to undergo phase transitions with loading. Furthermore, comparing present and previous findings, we suggest a general principle for design of hard ceramic solid solutions that are thermodynamically inclined to dissipate extreme mechanical stresses via transformation toughening mechanisms.

description: We consider a two-dimensional fully frustrated Josephson-junction array, which is driven uniformly by oscillating currents. As the temperature is lowered, there emerges a dynamic phase transition to an ordered state with nonzero dynamic order parameter for small currents. The transition temperature decreases monotonically with the driving amplitude, approaching zero at a certain critical value of the amplitude. Above the critical value, the disordered phase and the dynamically ordered phase are observed to appear alternatively. The characteristic stochastic resonance behavior of the system is also examined, which reveals that the resonance behavior of odd and even harmonics can be different according to the zero-temperature state.

description: One of the main purposes of publication is to influence on the new generation of knowledge through citation. Publishing is not enough: to transcend it is necessary to be cited. However, the issue is complex and requires attention on several points; one of them is the strategies of visibility that allow future citations. This systematic literature review (SLR) aims to analyze articles about citation impact, published between 2016 and 2018, filed on Scopus and Web of Science databases, to identify visibility strategies for scientific literature. The paper focuses on three aspects: the context and type of studies, the strategies used, and recommendations to increase citation impact in open access journals. Among the findings, it is possible to highlight the use of the Internet for visibility because of its tools. Also, the article recommends different strategies to be replicated in this type of publications.

description: We derive the one-loop perturbative formula of the redshift-space matter power spectrum after density field reconstruction in the Zeldovich approximation. We find that the reconstruction reduces the amplitudes of nonlinear one-loop perturbative terms significantly by partially erasing the nonlinear mode-coupling between density and velocity fields. In comparison with N-body simulations, we find that both the monopole and quadrupole spectra of reconstructed matter density fields agree with the one-loop perturbation theory up to higher wavenumber than those before reconstruction. We also evaluate the impact on cosmic growth rate assuming the survey volume and the number density like the Baryon Oscillation Spectroscopic Survey and find that the total error, including statistical and systematic ones due to one-loop approximation, decreases by half.

ZERNIKE WAVEFRONT SENSOR
EXOPLANET IMAGING AND SPECTROSCOPY

description: We propose to explore a cascade extreme Adaptive optics (ExAO) approach with a second stage based on a Zernike wavefront sensor (ZWFS) for exoplanet imaging and spectroscopy. Most exoplanet imagers currently use a single-stage ExAO to correct for the effects of atmospheric turbulence and produce high-Strehl images of observed stars in the near-infrared. While such systems enable the observation of warm gaseous companions around nearby stars, adding a second-stage AO enables to push the wavefront correction further and possibly observe colder or smaller planets. This approach is currently investigated in different exoplanet imagers (VLT/SPHERE, Mag-AOX, Subaru/SCExAO) by considering a Pyramid wavefront sensor (PWFS) in the second arm to measure the residual atmospheric turbulence left from the first stage. Since these aberrations are expected to be very small (a few tens of nm in the near-infrared domain), we propose to investigate an alternative approach based on the ZWFS. This sensor is a promising concept with a small capture range to estimate residual wavefront errors thanks to its large sensitivity, simple phase reconstruction and easiness of implementation. In this contribution, we perform preliminary tests on the GHOST testbed at ESO to validate this approach experimentally. Additional experiments with petalling effects are also showed, giving promising wavefront correction results. Finally, we briefly discuss a first comparison between PWFS-based and ZWFS-based second-stage AO to draw preliminary conclusions on the interests of both schemes for exoplanet imaging and spectroscopy with the upgrade of the current exoplanet imagers and the envisioned ExAO instruments for ELTs.

Explicit-Duration Markov Switching Models
Creators: name: Chiappa, Silvia
Publisher: name: arXiv

subject: FOS: Computer and information sciences

description: Markov switching models (MSMs) are probabilistic models that employ multiple sets of parameters to describe different dynamic regimes that a time series may exhibit at different periods of time. The switching mechanism between regimes is controlled by unobserved random variables that form a first-order Markov chain. Explicit-duration MSMs contain additional variables that explicitly model the distribution of time spent in each regime. This allows to define duration distributions of any form, but also to impose complex dependence between the observations and to reset the dynamics to initial conditions. Models that focus on the first two properties are most commonly known as hidden semi-Markov models or segment models, whilst models that focus on the third property are most commonly known as changepoint models or reset models. In this monograph, we provide a description of explicit-duration modelling by categorizing the different approaches into three groups, which differ in encoding in the explicit-duration variables different information about regime change/reset boundaries. The approaches are described using the formalism of graphical models, which allows to graphically represent and assess statistical dependence and therefore to easily describe the structure of complex models and derive inference routines. The presentation is intended to be pedagogical, focusing on providing a characterization of the three groups in terms of model structure constraints and inference properties. The monograph is supplemented with a software package that contains most of the models and examples described. The material presented should be useful to both researchers wishing to learn about these models and researchers wishing to develop them further.

description: Adiabatic (curvature) perturbations are produced during a period of cosmological inflation that is driven by a single scalar field, the inflaton. On particle physics grounds -- though -- it is natural to expect that this scalar field is coupled to other scalar degrees of freedom. This gives rise to oscillations between the perturbation of the inflaton field and the perturbations of the other scalar degrees of freedom, similar to the phenomenon of neutrino oscillations. Since the degree of the mixing is governed by the squared mass matrix of the scalar fields, the oscillations can occur even if the energy density of the extra scalar fields is much smaller than the energy density of the inflaton field. The probability of oscillation is resonantly amplified when perturbations cross the horizon and the perturbations in the inflaton field may disappear at horizon crossing giving rise to perturbations in scalar fields other than the inflaton. Adiabatic and isocurvature perturbations are inevitably correlated at the end of inflation and we provide a simple expression for the cross-correlation in terms of the slow-roll parameters.

description: In this letter, we present a novel and extremely fast steganalysis method of Voice over IP (VoIP) streams, driven by the need for a quick and accurate detection of possible steganography in VoIP streams. We firstly analyzed the correlations in carriers. To better exploit the correlation in code-words, we mapped vector quantization code-words into a semantic space. In order to achieve high detection efficiency, only one hidden layer is utilized to extract the correlations between these code-words. Finally, based on the extracted correlation features, we used the softmax classifier to categorize the input stream carriers. To boost the performance of this proposed model, we incorporate a simple knowledge distillation framework into the training process. Experimental results show that the proposed method achieves state-of-the-art performance both in detection accuracy and efficiency. In particular, the processing time of this method on average is only about 0.05\% when sample length is as short as 0.1s, attaching strong practical value to online serving of steganography monitor.

description: Variations in the width of a quantum well (QW) are known to be a source of broadening of the exciton line. Using low temperature near-field optical microscopy, we have exploited the dependence of exciton energy on well-width to show that in GaAs QWs, these seemingly random well-width fluctuations actually exhibit well-defined order -- strong long-range correlations appearing laterally, in the plane of the QW, as well as vertically, between QWs grown one on top of the other. We show that these fluctuations are correlated with the commonly found mound structure on the surface. This is an intrinsic property of molecular beam epitaxial growth.

description: We use high-resolution angle-resolved photoemission spectroscopy to investigate the electronic structure of the antiferromagnetic heavy fermion compound CePt2In7, which is a member of the CeIn3-derived heavy fermion material family. Weak hybridization among 4f electron states and conduction bands was identified in CePt2In7 at low temperature much weaker than that in the other heavy fermion compounds like CeIrIn5 and CeRhIn5. The Ce 4f spectrum shows fine structures near the Fermi energy, reflecting the crystal electric field splitting of the 4f^1_5/2 and 4f^1_7/2 states. Also, we find that the Fermi surface has a strongly three-dimensional topology, in agreement with density-functional theory calculations.

description: An analysis of the elastic and one-neutron removal channel for the reaction 8Li+208Pb reaction at energies around the Coulomb barrier is presented. For the elastic scattering, an optical model analysis of the experimental data is performed. The observed 7Li is interpreted as the superposition of the one-neutron transfer reaction, 208Pb(8Li,7Li)209Pb, and the breakup reaction. The separate contribution of each one of these processes has been calculated within the DWBA formalism. The sum of both contributions explains adequately the experimental angular distribution of 7Li.

description: Estimation in GARMA models has traditionally been carried out under the frequentist approach. To date, Bayesian approaches for such estimation have been relatively limited. In the context of GARMA models for count time series, Bayesian estimation achieves satisfactory results in terms of point estimation. Model selection in this context often relies on the use of information criteria. Despite its prominence in the literature, the use of information criteria for model selection in GARMA models for count time series have been shown to present poor performance in simulations, especially in terms of their ability to correctly identify models, even under large sample sizes. In this work, we study the problem of order selection in GARMA models for count time series, adopting a Bayesian perspective considering the Reversible Jump Markov Chain Monte Carlo approach. Monte Carlo simulation studies are conducted to assess the finite sample performance of the developed ideas, including point and interval inference, sensitivity analysis, effects of burn-in and thinning, as well as the choice of related priors and hyperparameters. Two real-data applications are presented, one considering automobile production in Brazil and the other considering bus exportation in Brazil before and after the COVID-19 pandemic, showcasing the method's capabilities and further exploring its flexibility.

description: The last ten years have seen the growth of linkages between many of the world’s cap-and-trade systems for greenhouse gases (GHGs), both directly between systems, and indirectly via connections to credit systems such as the Clean Development Mechanism. If nations have tried to act in their own self-interest, this proliferation of linkages implies that for many nations, the expected benefits of linkage outweighed expected costs. In this paper, we draw on the past decade of experience with carbon markets to test a series of hypotheses about why systems have demonstrated this revealed preference for linking. Linkage is a multi-faceted policy decision that can be used by political jurisdictions to achieve a variety of objectives, and we find evidence that many economic, political, and strategic factors — ranging from geographic proximity to integrity of emissions reductions — influence the decision to link. We also identify some potentially important effects of linkage, such as loss of control over domestic carbon policies, which do not appear to have deterred real-world decisions to link. These findings have implications for the future role that decentralized linkages may play in international climate policy architecture. The Kyoto Protocol has entered what is probably its final commitment period, covering only a small fraction of global GHG emissions. Under the Durban Platform for Enhanced Action, negotiators may now gravitate toward a hybrid system, combining top-down elements for establishing targets with bottom-up elements of pledge-and-review tied to national policies and actions. The incentives for linking these national policies are likely to continue to produce direct connections among regional, national, and sub-national cap-and-trade systems. The growing network of decentralized, direct linkages among these systems may turn out to be a key part of a future hybrid climate policy architecture.
