Ferroelectricity Induced by Incommensurate Magnetism

description: Ferroelectricity has been found to occur in several insulating systems, such as TbMnO$_3$ (TMO) and Ni$_3$V$_2$O$_8$ (NVO) which have more than one phase with incommensurately modulated long-range magnetic order. Here we give a phenomenological model which relates the symmetries of the magnetic structure as obtained from neutron diffraction to the development and orientation of a spontaneous ferroelectric moment induced by the magnetic ordering. This model leads directly to the formulation of a microscopic spin-phonon interaction which gives explains the observed phenomena. The results are given in terms of gradients of the exchange tensor with respect to generalized displacements for the specific example of NVO. It is assumed that these gradients will now be the target of first-principles calculations using the LDA or related schemes.

description: The science of cities seeks to understand and explain regularities observed in the world's major urban systems. Modelling the population evolution of cities is at the core of this science and of all urban studies. Quantitatively, the most fundamental problem is to understand the hierarchical organization of cities and the statistical occurrence of megacities, first thought to be described by a universal law due to Zipf, but whose validity has been challenged by recent empirical studies. A theoretical model must also be able to explain the relatively frequent rises and falls of cities and civilizations, and despite many attempts these fundamental questions have not been satisfactorily answered yet. Here we fill this gap by introducing a new kind of stochastic equation for modelling population growth in cities, which we construct from an empirical analysis of recent datasets (for Canada, France, UK and USA) that reveals how rare but large interurban migratory shocks dominate city growth. This equation predicts a complex shape for the city distribution and shows that Zipf's law does not hold in general due to finite-time effects, implying a more complex organization of cities. It also predicts the existence of multiple temporal variations in the city hierarchy, in agreement with observations. Our result underlines the importance of rare events in the evolution of complex systems and at a more practical level in urban planning.

description: For gamma-ray bursts (GRBs) with a plateau phase in the X-ray afterglow, a so called $L-T-E$ correlation has been found which tightly connects the isotropic energy of the prompt GRB ($E_{γ,\rm{iso}}$) with the end time of the X-ray plateau ($T_{a}$) and the corresponding X-ray luminosity at the end time ($L_{X}$). Here we show that there is a clear redshift evolution in the correlation. Furthermore, since the power-law indices of $L_{X}$ and $E_{γ,\rm{iso}}$ in the correlation function are almost identical, the $L-T-E$ correlation is insensitive to cosmological parameters and cannot be used as a satisfactory standard candle. On the other hand, based on a sample including 121 long GRBs, we establish a new three parameter correlation that connects $L_{X}$, $T_{a}$ and the spectral peak energy $E_{\rm{p}}$, i.e. the $L-T-E_{\rm{p}}$ correlation. This correlation strongly supports the so-called Combo-relation established by Izzo et al. (2015). After correcting for the redshift evolution, we show that the de-evolved $L-T-E_{\rm{p}}$ correlation can be used as a standard candle. By using this correlation alone, we are able to constrain the cosmological parameters as $Ω_{m}=0.389^{+0.202}_{-0.141}$ ($1σ$) for the flat $Λ$CDM model, or $Ω_{m}=0.369^{+0.217}_{-0.191}$, $w=-0.966^{+0.513}_{-0.678}$ ($1σ$) for the flat $w$CDM model. Combining with other cosmological probes, more accurate constraints on the cosmology models are presented.

description: Wildfires are a natural part of the boreal forest ecosystem, which is largely present in Alaska. However, in recent years, the fires seem to be more frequent and intense due to human-forced warming and an overall lengthening of the fire season, which affects local communities, flora and fauna. Alaskan ecosystems are already significantly exposed to impacts of climate change, not least due to temperature increase, which is almost twice the global average rate, largely due to a phenomenon known as Arctic amplification (US Global Change Research Program). Summer 2019 recorded some of the highest temperatures and lowest moisture levels since records are kept (1952) (NASA Earth Observatory). This led to an extreme fire season in the northern state, burning an area of over 1 million hectares. This situation additionally contributed to exacerbating climate change, since the CO2 stored in the soil and permafrost of these ecosystems had been released. Keeping forest fires under control is becoming an urgent and challenging task for the Arctic region. Predicting this type of events could improve preparedness and help to better protect the towns and communities that are at risk of destruction, e.g. help authorities make evacuations in time or allow the relocation of firefighting resources.

description: We present a mesoscopic model of the fluid-wall interactions for flows in microchannel geometries. We define a suitable implementation of the boundary conditions for a discrete version of the Boltzmann equations describing a wall-bounded single phase fluid. We distinguish different slippage properties on the surface by introducing a slip function, defining the local degree of slip for mesoscopic molecules at the boundaries. The slip function plays the role of a renormalizing factor which incorporates, with some degree of arbitrariness, the microscopic effects on the mesoscopic description. We discuss the mesoscopic slip properties in terms of slip length, slip velocity, pressure drop reduction (drag reduction), and mass flow rate in microchannels as a function of the degree of slippage and of its spatial distribution and localization, the latter parameter mimicking the degree of roughness of the ultra-hydrophobic material in real experiments. We also discuss the increment of the slip length in the transition regime, i.e. at O(1) Knudsen numbers. Finally, we compare our results with Molecular Dynamics investigations of the dependency of the slip length on the mean channel pressure and local slip properties (Cottin-Bizonne et al. 2004) and with the experimental dependency of the pressure drop reduction on the percentage of hydrophobic material deposited on the surface -- Ou et al. (2004).

description: Приблизившись в начале 1960-х гг. к показателям продолжительности жизни развитых стран, Россия снова стала отставать от них. Долговременные неблагоприятные тенденции смертности, усиленные кризисом 1990-х гг., наряду со значительным увеличением ожидаемой продолжительности жизни в западных и в некоторых восточных странах привели к новому огромному отрыву России от стран-лидеров. В начале 2000-х гг. отставание от них по ожидаемой продолжительности жизни при рождении достигало почти 20 лет у мужчин и 13 лет у женщин. Начиная с 2004 г. положение стало меняться, и эти разрывы несколько сократились, вернувшись к уровню, наблюдавшемуся в начале 1990-х гг. (12–15 лет у мужчин и 7–10 лет у женщин). Их дальнейшее сокращение потребует серьезного прорыва в борьбе со смертностью взрослого населения, особенно в средних возрастах, где положение сейчас наиболее неблагополучно. Пока не очень понятно, как нынешний уровень государственных расходов на здравоохранение (3,6% к ВВП в 2016 г.), один из самых низких в мире среди индустриализованных стран, соотносится с решением столь амбициозной и ресурсоемкой задачи, как повышение продолжительности жизни россиян до 78 лет к 2024 г. и до 80 лет к 2030 г.

description: Motivated by the desire to understand the leading order nonlinear gravitational wave interactions around arbitrarily rapidly rotating Kerr black holes, we describe a numerical code designed to compute second order vacuum perturbations on such spacetimes. A general discussion of the formalism we use is presented in (arXiv:2008.11770); here we show how we numerically implement that formalism with a particular choice of coordinates and tetrad conditions, and give example results for black holes with dimensionless spin parameters $a=0.7$ and $a=0.998$. We first solve the Teukolsky equation for the linearly perturbed Weyl scalar $Ψ_4^{(1)}$, followed by direct reconstruction of the spacetime metric from $Ψ_4^{(1)}$, and then solve for the dynamics of the second order perturbed Weyl scalar $Ψ_4^{(2)}$. This code is a first step toward a more general purpose second order code, and we outline how our basic approach could be further developed to address current questions of interest, including extending the analysis of ringdown in black hole mergers to before the linear regime, exploring gravitational wave "turbulence" around near-extremal Kerr black holes, and studying the physics of extreme mass ratio inspiral.

Development of ecologically-based planning tools for managing cumulative effects in Jasper National Park: the ecosite representation and breeding bird habitat effectiveness models
Creators: name: Dobson, Brenda
Publisher: name: University of British Columbia
Year: 2009

description: Increasingly, National Park Managers have begun to recognize the importance of understanding, assessing and managing cumulative effects. In Jasper National Park, the rarest habitat, namely the montane, contains the greatest intensity of human use and development in the park. I developed the Ecosite Representation and Breeding Bird Habitat Effectiveness Models to contribute to an established framework for assessing and managing cumulative effects in the high use area of the park. The Breeding Bird Model integrates call-count survey results, data delineating habitat types and quantifying human use with parameters developed from the literature in an Arc/info GIS. Similarly, the Ecosite Representation Model integrates habitat and human use data with a set of parameters derived from the literature. To assess cumulative effects on breeding bird habitat, I describe a functional relationship depicting the response of breeding bird species detected in the surveys to human activity and development. The relationship for ecosite representation assumes that within a disturbance distance of a human use feature, habitat is degraded. Through these relationships, data layers are integrated to predict cumulative effects, expressed as a change in the effectiveness of habitat for the indicators. This method tracks how the area lost and degraded changes over time and in response to different land use scenarios. Prior to using the models, I conducted a sensitivity analysis identifying the sources and influence of ecological uncertainty on model results. Following this, I completed a cumulative effects analysis which indicates that failure to assess and act on cumulative effects has resulted in impacts on both indicators concentrated in a group of montane habitat types. Development in Three Valley Confluence has predominantly been concentrated in eight habitat types, some of which are rare in abundance and the most important in the park for supporting breeding bird richness. Therefore, I recommend strategic land use planning to ensure new development and expansion does not continue within these habitat types and restoration efforts be undertaken to improve conditions for both indicators. I present several realistic options including planning based on clustering development, reducing access points, restoration and continuing development of a framework for cumulative effects assessment and management.

description: A modified version of this article has been published in the May 2007 issue of the journal Ecological Economics. This paper presents the first comprehensive analysis of municipal-level open space referenda, both the decision to hold a referendum and referendum results, across the entire contiguous United States. We find that municipalities populated by more educated, environmentally aware and politically left-leaning people and that experienced substantial population growth in surrounding areas were more likely to hold open space referenda than other municipalities. Overall, there are fewer statistically significant relationships in the referenda results estimation than in the selection estimation. Referenda support was significantly affected only by the finance mechanism, unemployment rate, education and region dummy variables. We find limited evidence of selection bias in the estimated referenda results equations.
Galactic Globular Clusters with Luminous X-Ray Binaries

Publisher: name: arXiv
Year: 2005
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: Luminous X-ray binaries (>1E34 erg/s, LMXBs) have a neutron star or black hole primary, and in globular clusters, most of these close binaries are expected to be have evolved from wider binaries through dynamical interactions with other stars. We sought to find a predictor of this formation rate that is representative of the initial properties of globular clusters rather than of the highly evolved core quantities. Models indicate the half-light quantities best reflect the initial conditions, so we examine whether the associated dynamical interaction rate, proportional to L^1.5 r^-2.5, is useful in understanding the presence of luminous LMXBs in the Galactic globular cluster system. We find that while LMXB clusters with large values of L^1.5 r^-2.5 preferentially host LMXBs, the systems must also have half-mass relaxation times below about 1E9 yr. This relaxation time effect probably occurs because several relaxation times are required to modify binary separations, a timescale that must be shorter than cluster ages. The frequency of finding an LMXB cluster is enhanced if the cluster is metal-rich and if it is close to the bulge region. The dependence upon metallicity is most likely due either to differing initial mass functions at the high mass end, or because bulge systems evolve more rapidly from tidal interactions with the bulge. This approach can be used to investigate globular cluster systems in external galaxies, where core properties are unresolved.

description: Obtaining digital representations of multivariate continuous-time (CT) signals is a challenge encountered in many signal processing systems. In practice, these signals are often acquired to extract some underlying information, i.e., for a specific task. Employing conventional task-agnostic analog-to-digital converters (ADCs), typically designed to minimize the mean squared error (MSE) in reconstructing the CT input signal, can be costly and energy-inefficient in such cases. In this work, we study task-based ADCs, which are designed to obtain a digital representation of a multivariate CT input process with the goal of recovering an underlying statistically related parameter vector, referred to as \emph{the task}. The proposed system employs analog filtering, uniform sampling, and scalar uniform quantization of the input process before recovering the task vector using a linear digital recovery filter. We optimize the analog and digital filters and derive closed-form expressions for the achievable MSE in recovering the task vector from a set of analog signals when utilizing ADCs with a fixed sampling rate and amplitude resolution. Based on our derivation, we provide guidelines for designing practical acquisition systems subject to a constraint on the bit rate. Our analysis proves that the intuitive approaches of either recovering the task vector solely in digital or designing the analog filter to estimate the task vector are inferior to the proposed joint design. We then consider the recovery of a set of matched filter outputs under a rate budget. We numerically verify our theoretical observations and demonstrate that task-based ADCs substantially outperform analog matched filtering as well as applying the matched filter solely in the digital domain.

description: The statistical properties of speckle patterns have important applications in optics, oceanography, and transport phenomena in disordered systems. Here we obtain closed-form analytic results for the amplitude distribution of speckle patterns formed by a random number of partial waves characterized by an arbitrary phase distribution, generalizing classical results of the random walk theory of speckle patterns. We show that the functional form of the amplitude distribution is solely determined by the distribution of the number of scatterers, while the phase distribution only influences the scale parameters. In the case of a non-random number of scatterers, we find an analytic expression for the amplitude distribution that extends the Rayleigh law to non-uniform random phases. For a negative binomial distribution of the number of scatterers, our results reveal that large fluctuations of the wave amplitudes become more pronounced in the case of biased random phases. We present numerical results that fully support our analytic findings.

Подбор претендентов на руководящую должность организаторов среднего звена – заведующего отделением анестезиологии и реанимации многопрофильных стационаров – комплексная задача, одним из вопросов которой является отбор наиболее достойных работников с изучением их деловых и личностных качеств. Цель работы – изучить управленческие компетенции руководящих кадров здравоохранения среднего звена на примере заведующих отделениями анестезиологии и реанимации многопрофильных стационаров. В исследование были включены 156 заведующих отделениями анестезиологии и реанимации многопрофильного стационара (врачей из резерва на должность заведующего). Исследование проведено в виде педагогического эксперимента, проходившего на базе кафедры общественного здоровья и здравоохранения Медико-биологического университета инноваций и непрерывного образования ФГБУ «Государственный научный центр – Федеральный медицинский биофизический центр им. А.И. Бурназяна» ФМБА России, с января 2015 по январь 2017 г. Результаты. Эмпирические исследования показали, что комплекс тренинговых занятий, направленных на развитие управленческих компетенций и стратегий, используемых при их реализации, является эффективным средством развития управленческой компетентности руководителей среднего звена – заведующих отделениями анестезиологии и реанимации многопрофильных стационаров, которые могут быть использованы в практическом здравоохранении и для заведующих других отделений. Полученные в исследовании результаты позволяют рассматривать развитие управленческой компетентности руководителей среднего звена многопрофильного стационара как управляемый и эффективный процесс. Практическое обучение заведующих отделениями анестезиологии и реанимации многопрофильных стационаров, а также врачей из резерва на должность заведующего, развитие управленческих компетенций и стратегий их реализации как системы предполагает развитие каждого вида и обеспечение их интеграции.

description: Production of biomass from native prairie species offers the opportunity to produce energy and chemicals while providing substantial ecological services in the Northern Great Plains. This paper analyzes the application of rapid pyrolysis to produce bio-oil, which has the potential for use as a low-grade fuel oil or as a source for extraction of valuable chemicals. Yields of bio-oil, the quantities of extractable chemicals, and chemical prices drive the economics of this concept, which has a more extensive track record utilizing wood chips. A spreadsheet model was developed to determine gross margins available to defray costs to extract and refine such chemical products as hydroxyacetaldehyde, phenol, formic acid, acetic acid and various resins. Although efforts to hydrolyze anhydroglucose were successful, efforts to produce ethanol from the resulting six-carbon sugars were unsuccessful in a related trial. To understand the overall project economics, it was necessary to consider the availability and productivity of lands in the Northern Great Plains that can provide low cost native prairie grasses including Big Bluestem and Switchgrass. Production economics and transportation economics were analyzed to determine the costs of native prairie grasses delivered to a plant capable of pyrolyzing the biomass. Competing technologies that could also use native prairie grasses are considered as well as policy alternatives important for production of energy and chemicals from native prairie grasses.

description: Guided by the analogy with the Rayleigh-Plesset dynamics of multielectron bubbles in superfluid He-4, we consider the cosmological FLRW evolution equation with additional cubic and sixth powers of the inverse of the scale factor of the universe. For the barotropic parameter w=2/3 (coasting universe), along with zero cosmological constant in the absence of viscous terms, by using the Sundman time as evolution parameter, we present parametric solutions for the scale factor of the universe in terms of rational expressions of Weierstrass elliptic functions and their particular cases thereof. For other values of the equation of state parameter w, such as w=-1, but also the same coasting case, we present a more standard discussion in the conformal time variable using solutions obtained by numerical integration.

On the Whitham equations for the defocusing nonlinear Schrodinger equation with step initial data

description: The behavior of solutions of the finite-genus Whitham equations for the weak dispersion limit of the defocusing nonlinear Schrodinger equation is investigated analytically and numerically for piecewise-constant initial data. In particular, the dynamics of constant-amplitude initial conditions with one or more frequency jumps (i.e., piecewise linear phase) are considered. It is shown analytically and numerically that, for finite times, regions of arbitrarily high genus can be produced; asymptotically with time, however, the solution can be divided into expanding regions which are either of genus-zero, genus-one or genus-two type, their precise arrangement depending on the specifics of the initial datum given. This behavior should be compared to that of the Korteweg-deVries equation, where the solution is devided into the regions which are either genus-zero or genus-one asymptotically. Finally, the potential application of these results to the generation of short optical pulses is discussed: the method proposed takes advantage of nonlinear compression via appropriate frequency modulation, and allows control of both the pulse amplitude and its width, as well as the distance along the fiber at which the pulse is produced.

description: Knowledge on evolving physical fields is of paramount importance in science, technology, and economics. Dynamical field inference (DFI) addresses the problem of reconstructing a stochastically driven, dynamically evolving field from finite data. It relies on information field theory (IFT), the information theory for fields. Here, the relations of DFI, IFT, and the recently developed supersymmetric theory of stochastics (STS) are established in a pedagogical discussion. In IFT, field expectation values can be calculated from the partition function of the full space-time inference problem. The partition function of the inference problem invokes a functional Dirac function to guarantee the dynamics, as well as a field-dependent functional determinant, to establish proper normalization, both impeding the necessary evaluation of the path integral over all field configurations. STS replaces these problematic expressions via the introduction of fermionic ghost and bosonic Lagrange fields, respectively. The action of these fields has a supersymmetry, which means there exists an exchange operation between bosons and fermions that leaves the system invariant. In contrast to this, measurements of the dynamical fields do not adhere to this supersymmetry. The supersymmetry can also be broken spontaneously, in which case the system evolves chaotically. This affects the predictability of the system and thereby make DFI more challenging. We investigate the interplay of measurement constraints with the non-linear chaotic dynamics of a simplified, illustrative system with the help of Feynman diagrams and show that the Fermionic corrections are essential to obtain the correct posterior statistics over system trajectories.

description: We investigate the dynamics of a double quantum dot charge qubit which is coupled to piezoelectric acoustic phonons, appropriate for GaAs heterostructures. At low temperatures, the phonon bath induces a non-Markovian dynamical behavior of the oscillations between the two charge states of the double quantum dot. Upon applying the numerically exact quasiadiabatic propagator path-integral scheme, the reduced density matrix of the charge qubit is calculated, thereby avoiding the Born-Markov approximation. This allows a systematic study of the dependence of the Q-factor on the lattice temperature, on the size of the quantum dots, as well as on the interdot coupling. We calculate the Q-factor for a recently realized experimental setup and find that it is two orders of magnitudes larger than the measured value, indicating that the decoherence due to phonons is a subordinate mechanism.

description: We present an analysis of an extended Rayleigh-Plesset (RP) equation for a three dimensional cell of microorganisms such as bacteria or viruses in some liquid, where the cell membrane in bacteria or the envelope (capsid) in viruses possess elastic properties. To account for rapid changes in the shape configuration of such microorganisms, the bubble membrane/envelope must be rigid to resist large pressures while being flexible to adapt to growth or decay. Such properties are embedded in the RP equation by including a pressure bending term that is proportional to the square of the curvature of the elastic wall. Analytical solutions to this extended equation are obtained in terms of elliptic functions.

description: Pedestrians are arguably one of the most safety-critical road users to consider for autonomous vehicles in urban areas. In this paper, we address the problem of jointly detecting pedestrians and recognizing 32 pedestrian attributes from a single image. These encompass visual appearance and behavior, and also include the forecasting of road crossing, which is a main safety concern. For this, we introduce a Multi-Task Learning (MTL) model relying on a composite field framework, which achieves both goals in an efficient way. Each field spatially locates pedestrian instances and aggregates attribute predictions over them. This formulation naturally leverages spatial context, making it well suited to low resolution scenarios such as autonomous driving. By increasing the number of attributes jointly learned, we highlight an issue related to the scales of gradients, which arises in MTL with numerous tasks. We solve it by normalizing the gradients coming from different objective functions when they join at the fork in the network architecture during the backward pass, referred to as fork-normalization. Experimental validation is performed on JAAD, a dataset providing numerous attributes for pedestrian analysis from autonomous vehicles, and shows competitive detection and attribute recognition results, as well as a more stable MTL training.

description: Let $s_1, s_2, s_3, \cdots$ be the set of squarefree numbers in ascending order. In this paper, we prove that the following asymptotic on moments of gaps between squarefree numbers \[ \sum_{s_{k+1} \le x} (s_{k+1} - s_k)^γ\sim B(γ) x \; \; \mbox{ with some constant} \; \; B(γ) > 0 \] is true for $0 \le γ< 3.75$. This improves the previous best range $0 \le γ< 3.6875$.

description: This paper discusses the Laser Astrometric Test Of Relativity (LATOR) mission. By using a combination of independent time-series of highly accurate gravitational deflection of light in the immediate proximity to the Sun along with measurements of the Shapiro time delay on the interplanetary scales (to a precision respectively better than $10^{-13}$ radians and 1 cm), LATOR will significantly improve our knowledge of relativistic gravity. The primary mission objective is to i) measure the key post-Newtonian Eddington parameter $γ$ with accuracy of a part in 10$^9$. $(1-γ)$ is a direct measure for presence of a new interaction in gravitational theory, and, in its search, LATOR goes a factor 30,000 beyond the present best result, Cassini's 2003 test. Other mission objectives include: ii) first measurement of gravity's non-linear effects on light to $\sim$0.01% accuracy; including both the traditional Eddington $β$ parameter and also the spatial metric's 2nd order potential contribution (never been measured before); iii) direct measurement of the solar quadrupole moment $J_2$ (currently unavailable) to accuracy of a part in 200 of its expected size; iv) direct measurement of the ``frame-dragging'' effect on light by the Sun's rotational gravitomagnetic field to one percent accuracy. LATOR's primary measurement pushes to unprecedented accuracy the search for cosmologically relevant scalar-tensor theories of gravity by looking for a remnant scalar field in today's solar system. The key element of LATOR is a geometric redundancy provided by the laser ranging and long-baseline optical interferometry. We discuss the mission and optical designs of this proposed experiment.

description: The Hennessy and Wahl model of optimal grain blending and segregation (GBS) is extended to the case where it is not possible to separate components within a load. Analytical solutions are not available when segregation is the optimal strategy, and so solutions are obtained with nonlinear optimization. The model is then used to determine the optimal sorting of hard red winter wheat by protein content. Most of the benefits from sorting can be obtained with only two bins.
