description: We investigate conditions for "simultaneous normalizability" of a family of reduced schemes, i.e., the normalization of the total space normalizes, fiber by fiber, each member of the family. The main result (under more general conditions) is that a flat family of reduced equidimensional projective complex varieties X_y with parameter y ranging over a normal space--algebraic or analytic--admits a simultaneous normalization if and only if the Hilbert polynomial of the integral closure of the structure sheaf O_{X_y} is locally independent of y. When the X_y are curves projectivity is not needed, and the statement reduces to the well known δ-constant criterion of Teissier. Proofs are basically algebraic, analytic results being related via standard techniques (Stein compacta, etc.) to more abstract algebraic ones.

description: It has recently been realized that the first-order moment of the Berry curvature, namely the Berry curvature dipole (BCD) can give rise to non-linear current in a wide variety of time-reversal invariant and non-centrosymmetric materials. While the BCD in two-dimensional Dirac systems is known to be finite only in the presence of either substantial spin-orbit coupling where low-energy Dirac quasiparticles form tilted cones or higher order warping of the Fermi surface, we argue that the low-energy Dirac quasiparticles arising from the merging of a pair of Dirac points without any tilt or warping of the Fermi surface can lead to a non-zero BCD. Remarkably, in such systems, the BCD is found to be independent of Dirac velocity as opposed to the Dirac dispersion with a tilt or warping effects. We further show that the proposed systems can naturally host helicity-dependent photocurrent due to their linear momentum-dependent Berry curvatures. Finally, we discuss an important byproduct of this work, i.e., nonlinear anomalous Nernst effect as a second-order thermal response.

description: Exploiting a rotating Schwarzschild black hole metric, we study hydrodynamic properties of perfect fluid whirling inward toward the black holes along a conical surface. On the equatorial plane of the rotating Schwarzschild black hole, we derive radial equations of motion with effective potentials and the Euler equation for steady state axisymmetric fuid. Moreover, numerical analysis is performed to figure out effective potentials of particles on the rotating Schwarzschild manifolds in terms of angular velocity, total energy and angular momentum per unit rest mass. Higher dimensional global embeddings are also constructed inside and outside the event horizons of the rotating Schwarzschild black holes.

description: The paper contains results of research realized in the rural area of Ucayali region in Peru, situated in the tropical zone in the Central East of the country. With the use of data acquired from agroforestry research on the demonstration plots and questionnaire survey on farmers´ households, the objective is to assess the economic effects of designed agroforestry multi-strata system by means of ex-ante approach. It was found out, that unfavorable financial results in first two years of the system, long production cycle of timber trees and low price of timber represent the principal challenges for adoption of agroforestry systems. The results drawn from the LP modeling described in this paper provided useful insight into the household’s economy which is based on agroforestry production system. The results were elaborated within the research intention IVZ MSM 6046070906.

description: Optical hyperspectral imaging based on absorption and scattering of photons at the visible and adjacent frequencies denotes one of the most informative and inclusive characterization methods in material research. Unfortunately, restricted by the diffraction limit of light, it is unable to resolve the nanoscale inhomogeneity in light-matter interactions, which is diagnostic of the local modulation in material structure and properties. Moreover, many nanomaterials have highly anisotropic optical properties that are outstandingly appealing yet hard to characterize through conventional optical methods. Therefore, there has been a pressing demand in the diverse fields including electronics, photonics, physics, and materials science to extend the optical hyperspectral imaging into the nanometer length scale. In this work, we report a super-resolution hyperspectral imaging technique that simultaneously measures optical absorption and scattering spectra with the illumination from a tungsten-halogen lamp. We demonstrated sub-5 nm spatial resolution in both visible and near-infrared wavelengths (415 to 980 nm) for the hyperspectral imaging of strained single-walled carbon nanotubes (SWNT) and reconstructed true-color images to reveal the longitudinal and transverse optical transition-induced light absorption and scattering in the SWNTs. This is the first time transverse optical absorption in SWNTs were clearly observed experimentally. The new technique provides rich near-field spectroscopic information that had made it possible to analyze the spatial modulation of band-structure along a single SWNT induced through strain engineering.

description: This article focuses on the voting behaviour of citizens in rural areas of the Czech Republic. Within the theoretical embodiment of the relationships between the individual in a social structure and voting behaviour, a so-called social-structural model for voting behaviour is often mentioned. However, when explaining the behaviour of the voting behaviour of citizens living under the conditions of the Czech Republic the applicability of this model is of course disputable. Due to the predominant inconsistencies of the social status of citizens of rural areas, it is not at all possible to determine the hypothesis of the applicability of a social-structural model of voting behaviour for citizens living in the conditions of the Czech rural countryside. The aim of this article is, through a case study of Zatec region, to prove the predominant (in)consistency of the social status of the given population.

description: We demonstrate that in an inversion-asymmetric two-dimensional electron system 2DES with both Rashba and Dresselhaus spin-orbit couplings taken into account, certain transport directions on which no spin precession occurs can be found when the injected spin is properly polarized. By analyzing the expectation value of spin with respect to the injected electron state on each space point in the 2DES, we further show that the adjacent regions with technically reachable widths along these directions exhibit nearly conserved spin. Hence a possible application in semiconductor spintronics, namely, precessionless spin transport wire, is proposed.

The mean value of the cross-correlation coefficients, plotted as a function of R_{4/2} has deep minima at values of R_{4/2}=2.2 and 2.9, which correspond to the critical dynamical symmetries of the interacting Boson model. The distribution of the calculated coefficients for nuclei belonging to different R_{4/2} classes has different pattern.

description: The subject of the relationship between state budget and trade balance is important as economic subject, not only at the level of developing countries, but also at of advanced ones, too. Such importance emerged clearly when 1980s witnessed in United States of America a deficit in both state budget and trade balance, which was called at that time as the twin or dual deficit. We can say that the analysis of relationship between state budget and trade balance states the extent of mutual effect between financial and trade policies of any economy, namely; any change in the outcome of either one may affect the other in the same degree. To put in other words, the instruments of financial policy represented by total incomes and total expenditures can affect the trade balance through the movement of exports and imports and vice-versa. One tracing properties and features of Libyan economy may remark its dependence greatly on the public sector in financing developmental projects and making development generally, as well as its dependence on incomes to supply consumer and investment goods. Further, it depends in collecting its incomes of foreign currency on exports of chief source which is crude oil. So, study and analysis of relationship between state budget and trade balance of Libyan economy means to study and analyze relationship of public sector through the state budget, with the external sector expressed as the external trade through trade balance.

description: Iteratively refining and critiquing sketches are crucial steps to developing effective designs. We introduce Scones, a mixed-initiative, machine-learning-driven system that enables users to iteratively author sketches from text instructions. Scones is a novel deep-learning-based system that iteratively generates scenes of sketched objects composed with semantic specifications from natural language. Scones exceeds state-of-the-art performance on a text-based scene modification task, and introduces a mask-conditioned sketching model that can generate sketches with poses specified by high-level scene information. In an exploratory user evaluation of Scones, participants reported enjoying an iterative drawing task with Scones, and suggested additional features for further applications. We believe Scones is an early step towards automated, intelligent systems that support human-in-the-loop applications for communicating ideas through sketching in art and design.

description: We set up the classical wave equation for a particle formed of an oscillatory zero-rest-mass charge together with its resulting electromagnetic waves, traveling in a potential field $V$ in a susceptible vacuum. The waves are Doppler-displaced upon the source motion, and superpose into a total, traveling- and in turn a standing- beat wave, or de Broglie phase wave, described by a corresponding total classical wave equation. By back-substitution of the explicitly known total, standing beat wave function and upon appropriate reductions at classic-velocity limit, we separate out from the total a component wave equation describing the kinetic motion of particle, which is equivalent to the Schrödinger equation. The Schrödinger wave function follows to be the envelope function of the standing beat wave at classic-velocity limit.

The analysis is aimed at deriving the fundamental relationships between milk prices at the individual levels of the chosen vertical. The results are then validated with the use of statistical hypotheses testing. From the derived single equation models, it is clear that there is a strong difference in the leverage of individual factors influencing the price at different levels of the milk value chain.

It introduces the concept of social responsibility, the so-called triple-bottom line, in terms of which the company focuses not only on the economic growth but it also takes into account environmental and social aspects of its business activities. The article presents five norms and standards which stem from the triplebottom line concept. The norms and standards are in the article briefly characterised, which is followed by their comparison based on four previously stated criteria. The results of the comparison show that there is no such norm which would meet current company requirements.

description: We present comparisons between 3+1D quasiparticle anisotropic hydrodynamics (aHydroQP) predictions for a large set of bulk observables and experimental data collected in 5.02 TeV Pb-Pb collisions. We make aHydroQP predictions for identified hadron spectra, identified hadron average transverse momentum, charged particle multiplicity as a function of pseudorapidity, the kaon-to-pion ($K/π$) and proton-to-pion ($p/π$) ratios, and integrated elliptic flow. We compare to data collected by the ALICE collaboration in 5.02 TeV Pb-Pb collisions. We find that these bulk observables are quite well described by aHydroQP with an assumed initial central temperature of $T_0=630$ MeV at $τ_0 = 0.25$ fm/c and a constant specific shear viscosity of $η/s=0.159$ and a peak specific bulk viscosity of $ζ/s = 0.048$. In particular, we find that the momentum dependence of the kaon-to-pion ($K/π$) and proton-to-pion ($p/π$) ratios reported recently by the ALICE collaboration are extremely well described by aHydroQP in the most central collisions.

We demonstrate that, in a sharp contrast to the conventional left-handed perfect lens at $ε=μ=-1$, where $ε$ is the dielectric constant and $μ$ is the magnetic permeability, the birefringent left-handed lens can focus either TE or TM polarized waves or both of them, allowing a spatial separation of the TE and TM images. We discuss several applications of the birefringent left-handed lenses such as the beam splitting and near-field diagnostics at the sub-wavelength scale.

description: The objective of our research is to investigate retailer market conduct in the sale of beverage milk using a structural model of consumer behavior and retailer optimality conditions that embrace a range of competitive scenarios. The study is based on an aggregate level analysis of retailer behavior with milk quantity used as a strategic variable. We contribute to the literature by employing a Generalized Quadratic Almost Ideal Demand System (GQAIDS) to model milk demand. Furthermore, we derive the retailer optimality conditions that incorporate the slopes of inverse GQAIDS demand curves for the products under study. Lastly, we apply this generalized structural model to study the retailer behavior in marketing national brand (NB) and private label (PL) milk. The market in question is rather concentrated at the downstream level; however we believe that the retailer behavior is most consistent with a competitive atmosphere. Moreover, the results support the conjecture that retailers mainly use the leading NB milk to assure some store traffic while utilizing PL brands for rent extraction.

description: We use the numerical flow-equation renormalization method to study a nonlinear bath at low temperatures. The model of our nonlinear bath consists of a single two-level system coupled to a linear oscillator bath. The effects of this nonlinear bath are analyzed by coupling it to a spin, whose relaxational dynamics under the action of the bath is studied by calculating spin-spin correlation functions. As a first result, we derive flow equations for a general four-level system coupled to an oscillator bath, valid at low temperatures. We then treat the two-level system coupled to our nonlinear bath as a special case of the dissipative four-level system. We compare the effects of the nonlinear bath with those obtained using an effective linear bath, and study the differences between the two cases at low temperatures.

description: Increasingly, environmental problems are recognized to involve linkages across multiple environmental variables (e.g., pollution and a fishery). Prior work on managing these complex, linked systems generally focuses on efficiency rather than implementation. However, implementation is important and will generally involve changing human behaviors within the multiple economic sectors that impact upon the multiple environmental variables. Tradable permit markets are generally seen as a coordinating mechanism, within a particular regulated sector, that enhances efficiency by incentivizing agents to respond to behavioral choices of others within the sector. However, prior work stops short of coordinating behaviors across multiple sectors for cases where society benefits from regulation in both sectors and one sector harms the other. We analyze a multi-sector permit market involving both the externality-generating sector and the affected sector. This multi-sector market provides a mechanism for agents in one sector to respond to environmental behaviors made within the other sector. Moreover, unlike traditional permit markets in which the regulated externality sector incurs only costs, we show that the multi-sector market generates efficiency gains that may be redistributed using appropriate allocations of initial endowments. Accordingly, the multi-sector market may generate gains that benefit both sectors, resulting in a win-win outcome for both sectors. We use a simple example of a polluted fishery to illustrate the approach.

Exact calculation of the one-loop effective Higgs potential at finite temperature suggests that for the Higgs boson with its mass between 115 and 132 GeV the strongly first-order electroweak phase transition is possible if a dimension-six operator is present.

description: We use propensity score matching to estimate the level of additionality from enrollment in federal cost-share programs for six agricultural conservation practices. We analyze farmer conservation adoption decisions based on survey data of farmers in southwest Ohio. We also develop a new methodological approach to decompose the average treatment effect on the treated (ATT) according to the relative contributions of adopters and non-adopters. Our results indicate that enrollment in federal conservation programs achieves positive and significant levels of additionality for each of the six practices. But the percent additionality varies dramatically between practices types. Specifically, the percent additionality is highest for filter strips (92.0%), hayfields (91.0%), and cover crops (86.7%), while it is lowest for conservation tillage (18.0%).

description: We report Chandra X-ray Observatory and 1.4 GHz Australian Long Baseline Array (LBA) observations of the radio galaxy PKS 2153--69 and its environment. The Chandra image reveals a roughly spherical halo of hot gas extending out to 30 kpc around PKS 2153--69. Two depressions in the surface brightness of the X-ray halo correspond to the large scale radio lobes, and interpreting these as cavities inflated with radio plasma we infer a jet power of 4x10^42 erg/s. Both radio lobes contain hot spots that are detected by Chandra. In addition, the southern hot spot is detected in the 1.4 GHz LBA observation, providing the highest linear resolution image of a radio lobe hot spot to date. The northern hot spot was not detected in the LBA observation. The radio to X-ray spectra of the hot spots are consistent with a simple power law emission model. The nucleus has an X-ray spectrum typical of a type 1 active galactic nucleus, and the LBA observation shows a one-sided nuclear jet on 0.1" scales. Approximately 10" northeast of the nucleus, X-ray emission is associated with an extra-nuclear cloud. The X-ray emission from the cloud can be divided into two regions, an unresolved western component associated with a knot of radio emission (in a low resolution map), and a spatially extended eastern component aligned with the pc-scale jet and associated with highly ionized optical line-emitting clouds. The X-ray spectrum of the eastern component is very soft (Gamma > 4.0 for a power law model or kT ~0.22 keV for a thermal plasma). The LBA observation did not detect compact radio emission from the extra-nuclear cloud. (Abstract truncated).

description: We analyze the time-varying volatility in crude oil, heating oil, and natural gas futures markets by incorporating changes in important macroeconomic variables and major political and weather-related events into the conditional variance equations. We allow asymmetric responses to random disturbances in each market as well as to good and bad economic news in the overall economy. We also investigate whether there are spillover effects among these energy markets. A bi-directional volatility spillover effect is found between heating oil and natural gas markets. Among the macro variables considered the spread between the 10-year and 2-year Treasury constant maturity rate is found to have a positive relationship between the volatilities of all commodities. The events that had a major impact on the volatilities of energy commodities include the September 11th terrorist attacks, hurricane Katrina, and the 2008 U.S. financial crisis. The theory of storage is not supported in any of the three commodities. Seasonality and day-of-the week effects are found for all three commodities. Key

Log-Poisson Statistics and Extended Self-Similarity in Driven Dissipative Systems

description: The Bak-Chen-Tang forest fire model was proposed as a toy model of turbulent systems, where energy (in the form of trees) is injected uniformly and globally, but is dissipated (burns) locally. We review our previous results on the model and present our new results on the statistics of the higher-order moments for the spatial distribution of fires. We show numerically that the spatial distribution of dissipation can be described by Log-Poisson statistics which leads to extended self-similarity (ESS). Similar behavior is also found in models based on directed percolation; this suggests that the concept of Log-Poisson statistics of (appropriately normalized) variables can be used to describe scaling not only in turbulence but also in a wide range of driven dissipative systems.

description: A variety of screening approaches have been proposed to diagnose epileptic seizures, using electroencephalography (EEG) and magnetic resonance imaging (MRI) modalities. Artificial intelligence encompasses a variety of areas, and one of its branches is deep learning (DL). Before the rise of DL, conventional machine learning algorithms involving feature extraction were performed. This limited their performance to the ability of those handcrafting the features. However, in DL, the extraction of features and classification are entirely automated. The advent of these techniques in many areas of medicine, such as in the diagnosis of epileptic seizures, has made significant advances. In this study, a comprehensive overview of works focused on automated epileptic seizure detection using DL techniques and neuroimaging modalities is presented. Various methods proposed to diagnose epileptic seizures automatically using EEG and MRI modalities are described. In addition, rehabilitation systems developed for epileptic seizures using DL have been analyzed, and a summary is provided. The rehabilitation tools include cloud computing techniques and hardware required for implementation of DL algorithms. The important challenges in accurate detection of automated epileptic seizures using DL with EEG and MRI modalities are discussed. The advantages and limitations in employing DL-based techniques for epileptic seizures diagnosis are presented. Finally, the most promising DL models proposed and possible future works on automated epileptic seizure detection are delineated.
Numerical study of fractionalization in an Easy-axis Kagome antiferromagnet

description: Based on exact numerical calculations, we show that the generalized Kagome spin model in the easy axis limit exhibits a spin liquid, topologically degenerate ground state over a broad range of phase space. We present an (to our knowledge the first) explicit calculation of the gap (and dispersion) of ``vison'' excitations, and exponentially decaying spin and vison 2-point correlators, hallmarks of deconfined, fractionalized and gapped spinons. The region of the spin liquid phase includes a point at which the model is equivalent to a Heisenberg model with purely two-spin interactions. Beyond this range, a negative ``potential'' term tunes a first order transition to a magnetic ordered state. The nature of the phase transition is also discussed in light of the low energy spectrum. These results greatly expand the results and range of a previous study of this model in the vicinity of an exactly soluble point.

description: With the rise in obesity levels across the nation, policy makers and public interest groups are taking more interest in advertising of unhealthful foods. The Better Business Bureau has formed the Children’s Food and Beverage Advertising Initiative (CFBAI), which has recruited carbonated soft drink (CSD) manufactures to voluntarily restrict their advertising directed at children less than 12 years of age. This research explores the effects of the CFBAI on firm level advertising to children and adults using nonlinear time series processes. Estimated ARCH processes are significant in all models and capture varying pulse-advertising strategies by all major firms. We find that the market leader does in fact reduce its advertising to both adults and children and the second largest firm reduces advertising to adults. Advertising for the non-participating firm, however, increased for adults following the ban. The results emphasize the potential benefits and difficulty of coordinating cooperative behavior in this type of industry. It appears that policy strategies of this nature may be more effective if directed at industries as a whole and not at individual firms.

Assimilation of atmospheric infrasound data to constrain tropospheric and stratospheric winds

description: This data assimilation study exploits infrasound from explosions to probe an atmospheric wind component from the ground up to stratospheric altitudes. Planned explosions of old ammunition in Finland generate transient infrasound waves that travel through the atmosphere. These waves are partially reflected back towards the ground from stratospheric levels, and are detected at a receiver station located in northern Norway at 178 km almost due North from the explosion site. The difference between the true horizontal direction towards the source and the backazimuth direction (the horizontal direction of arrival) of the incoming infrasound wave-fronts, in combination with the pulse propagation time, are exploited to provide an estimate of the average cross-wind component in the penetrated atmosphere. We perform offline assimilation experiments with an ensemble Kalman filter and these observations, using the ERA5 ensemble reanalysis atmospheric product as background (prior) for the wind at different vertical levels. We demonstrate that information from both sources can be combined to obtain analysis (posterior) estimates of cross-winds at different vertical levels of the atmospheric slice between the explosion site and the recording station. The assimilation makes greatest impact at the 12-60 km levels, with some changes with respect to the prior of the order of 0.1-1.0 m/s, which is a magnitude larger than the typical standard deviation of the ERA5 background. The reduction of background variance in the higher levels often reached 2-5%. This is the first published study demonstrating techniques to implement assimilation of infrasound data into atmospheric models. It paves the way for further exploration in the use of infrasound observations - especially natural and continuous sources - to probe the middle atmospheric dynamics and to assimilate these data into atmospheric model products.

description: Besides being a fascinating class of new materials, magnetic molecules provide the opportunity to study concepts of condensed matter physics in zero dimensions. This contribution will exemplify the impact of molecular magnetism on concepts of frustrated spin systems. We will discuss spin rings and the unexpected rules that govern their low-energy behavior. Rotational bands, which are experimentally observed in various molecular magnets, provide a useful, simplified framework for characterizing the energy spectrum, but there are also deviations thereof with far-reaching consequences. It will be shown that localized independent magnons on certain frustrated spin systems lead to giant magnetization jumps, a new macroscopic quantum effect. In addition a frustration-induced metamagnetic phase transitions will be discussed, which demonstrates that hysteresis can exist without anisotropy. Finally, it is demonstrated that frustrated magnetic molecules could give rise to an enhanced magnetocaloric effect.
