description: We use three dimensional time-dependent Schrödinger equation (3D--TDSE) to calculate angular electron momentum distributions and photoelectron spectra of atoms driven by spatially inhomogeneous fields. An example for such inhomogeneous fields is the locally enhanced field induced by resonant plasmons, appearing at surfaces of metallic nanoparticles, nanotips and gold bow-tie shape nanostructures. Our studies show that the inhomogeneity of the laser electric field plays an important role in the above threshold ionization process in the tunneling regime, causing significant modifications to the electron momentum distributions and photoelectron spectra, while its effects in the multiphoton regime appear to be negligible. Indeed, through tunneling ATI process, one can obtain higher energy electrons as well as high degree of asymmetry in the momentum space map. In this study we consider near infrared laser fields with intensities in the mid-$10^{14}$ W/cm$^{2}$ range and we use linear approximation to describe their spatial dependence. We show that in this case it is possible to drive electrons with energies in the near-keV regime. Furthermore, we study how the carrier envelope phase influences the emission of ATI photoelectrons for few-cycle pulses. Our quantum mechanical calculations are fully supported by their classical counterparts.

description: By using laboratory x-ray photoemission spectroscopy (XPS) and hard x-ray photoemission spectroscopy (HX-PES) at a synchrotron facility, we report an empirical semi-quantitative relationship between the valence/core-level x-ray photoemission spectral weight and electrical conductivity in La_{1-x}Sr_{x}MnO_{3} as a function of x. In the Mn 2p_{3/2} HX-PES spectra, we observed the shoulder structure due to the Mn^{3+} well-screened state. However, the intensity at x=0.8 was too small to explain its higher electrical conductivity than x=0.0, which confirms our recent analysis on the Mn 2p_{3/2} XPS spectra. The near-Fermi level XPS spectral weight was found to be a measure of the variation of electrical conductivity with x in spite of a far lower energy resolution compared with the energy scale of the quasiparticle (coherent) peak because of the concurrent change of the coherent and incoherent spectral weight.

description: Este artigo apresenta o perfil ambiental e económico dos betões de ultraelevado desempenho (Ultra High-Performance Concrete – UHPC) com formulações alternativas eco-eficientes desenvolvidos no âmbito do projeto Pre-Shell. Este estudo considerou um UHPC de referência e o levantamento do estado da arte relativo à sustentabilidade ambiental e económica destes materiais, a fim de potenciar a minimização dos impactes causados pelos componentes deste produto. Uma vez que o cimento usado nos UHPC é um dos grandes poluidores atmosféricos da indústria da Construção Civil, o projeto Pre-Shell visou a redução da dosagem desse material na composição do produto final através da adição de materiais cimentícios suplementares (Supplementary Cementitious Materials - SCMs). Obtiveram-se os resultados esperados para o contributo do cimento para os impactes ambientais das composições, mas as fibras metálicas também apresentaram valores relevantes para as análises de eco-eficiência na produção das misturas, tendo nomeadamente impacte negativo nas dimensões ambiental e económica.
description: This paper presents the environmental and economic profile of Ultra High-Performance Concrete (UHPC) with alternative eco-efficient formulations developed under the Pre-Shell project. This study considered a reference UHPC and the state of the art regarding the environmental and economic sustainability of these materials, in order to minimise the impacts caused by their components. Since the cement used in UHPCs is one of the biggest air polluters in the construction industry, the Pre-shell project aimed to reduce the dosage of this material in the final product by adding Supplementary Cementitious Materials (SCMs). The expected results for the contribution of cement to the environmental impacts of the compositions were achieved, but the metal fibres also showed relevant values for the eco-efficiency analyses in the production of the mixtures, having namely a negative impact on the environmental and economic dimensions.

description: Stability and reconnection of magnetic fields play a fundamental role in natural and man-made plasma. In these applications the field's topology determines the stability of the magnetic field. Here I will describe the importance of one topology quantifier, the magnetic helicity, which impedes any free decay of the magnetic energy. Further constraints come from the fixed point index which hinders the field to relax into the Taylor state.

Comparative effects of mesh resolution on predictions of shallow water flow

Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2018

description: - How can we generate more effcient and objectively built multiscale meshes for shallow water flow solvers?
- The finite element mesh development process often is challenging and time consuming.
     1. Accurate representation of boundaries while maintaining
numerical stability.
     2. Efficient and objective placement of resolution that does not exhaust your computing resources.
- Many model developers employ the expensive but reliable place-high-resolution-everywhere approach and run with a timestep between 0.25 s and 1 s.
- This is a suboptimal solution and perhaps we can place resolution only where it is necessary to produce lighter grids.

Spherical collapse model with shear and angular momentum in dark energy cosmologies

description: We study, for the first time, how shear and angular momentum modify typical parameters of the spherical collapse model, in dark energy dominated universes. In particular, we study the linear density threshold for collapse $δ_\mathrm{c}$ and the virial overdensity $Δ_\mathrm{V}$, for several dark-energy models and its influence on the cumulative mass function. The equations of the spherical collapse are those obtained in Pace et al. (2010), who used the fully nonlinear differential equation for the evolution of the density contrast derived from Newtonian hydrodynamics, and assumed that dark energy is present only at the background level. With the introduction of the shear and rotation terms, the parameters of the spherical collapse model are now mass-dependant. The results of the paper show, as expected, that the new terms considered in the spherical collapse model oppose the collapse of perturbations on galactic scale giving rise to higher values of the linear overdensity parameter with respect to the non-rotating case. We find a similar effect also for the virial overdensity parameter. For what concerns the mass function, we find that its high mass tail is suppressed, while the low mass tail is slightly affected except in some cases, e.g. the Chaplygin gas case.

The Euler-Riemann Gases, and Partition Identities

description: The Euler theorem in partition theory and its generalization are derived from a non-interacting quantum field theory in which each bosonic mode with a given frequency is equivalent to a sum of bosonic mode whose frequency is twice ($s$-times) as much, and a fermionic (parafermionic) mode with the same frequency. Explicit formulas for the graded parafermionic partition functions are obtained, and the inverse of the graded partition function (IGPPF), turns out to be bosonic (fermionic) partition function depending on the parity of the order $s$ of the parafermions. It is also shown that these partition functions are generating functions of partitions of integers with restrictions. If the parity of the order $s$ is even, then mixing a system of parafermions with a system whose partition function is (IGPPF), results in a system of fermions and bosons. On the other hand, if the parity of $s$ is odd, then, the system we obtain is still a mixture of fermions and bosons but the corresponding Fock space of states is truncated. It turns out that these partition functions are given in terms of the Jacobi theta function $θ_{4}$, and generate sequences in partition theory. Our partition functions coincide with the overpartitions, and jagged partitions in conformal field theory. Also, The partition functions obtained are related to the Ramond characters of the superconformal minimal models, and in the counting of the Moore-Read edge spectra that appear in the fractional quantum Hall effect. The different partition functions for the Riemann gas that are the counter parts of the Euler gas are obtained by a simple change of variables. In particular the counter part of the Jacobi Theta function is $\frac{ζ(2t)}{ζ(t)^2}$.

description: The dynamics of a spring-block train placed on a moving conveyor belt is investigated both by simple experiments and computer simulations. The first block is connected by spring to an external static point, and due to the dragging effect of the belt the blocks undergo complex stick-slip dynamics. A qualitative agreement with the experimental results can only be achieved by taking into account the spatial inhomogeneity of the friction force on the belt's surface, modeled as noise. As a function of the velocity of the conveyor belt and the noise strength, the system exhibits complex, self-organized critical, sometimes chaotic dynamics and phase transition-like behavior. Noise induced chaos and intermittency is also observed. Simulations suggest that the maximum complexity of the dynamical states is achieved for a relatively small number of blocks, around five.

description: Alginate-gelatin systems are used in a wide range of applications, e.g., foods, cosmetics, drugs, and medicine. To target the techno-functionalities of alginate-gelatin systems such as texture, stability, or appearance it is necessary to understand the structure formation of gel systems, which is influenced by the molecular interactions and the phase behaviour. Therefore, the aim of this study was to characterise the molecular interactions and phase behaviour of dilute alginate-gelatin systems. For this purpose, we analysed alginate, gelatin A and their mixtures at pH 7. First, we characterised the effect of the sodium chloride concentration on the single polymer solutions by measuring the critical overlap concentration, the zeta potential, intrinsic viscosity, the Huggins coefficient as well as the molecular weight and the second virial coefficient. To gain a better understanding of the molecular interactions between alginate and gelatin, we determined the Huggins coefficient and the interaction parameter by Wolf as a function of mixing ratio, NaCl and urea concentration. Additionally, we calculated the second cross-virial coefficient. Lastly, we characterised the influence of the interactions on the secondary structure of gelatin by Fourier-transform-infrared-spectroscopy. The attractive interactions between alginate and gelatin potentially enabling the formation of soluble complexes, were demonstrated as deviations from additivity of intrinsic viscosity and negative cross-virial coefficients. Interestingly, the Wolf interaction parameter was affected by the NaCl concentration and the mixing ratio, whereas the presence of urea showed no impact. This indicates that the attractive interactions of alginate and gelatin A at pH 7 is rather caused by electrostatic interactions than hydrogen bonds. The present study clarifies the relevance of hydrogen bonds and electrostatic interactions as well as the impact of mixing ratio and solvent properties on the phase behaviour of alginate-gelatin systems. The insights contribute to a better understanding of the structure formation of concentrated alginate-gelatin systems, levelling the path to specific modifications of functionality.

Der Arabische Frühling im algerischen Blick. Aus den Erfahrungen des algerischen Bürgerkriegs lernen. Literarisches Schaffen und intellektuelles Engagement bei Boualem Sansal und Maїssa Bey
Creators: name: Wilzek, Jessica
Publisher: name: HeLix - Dossiers zur romanischen Literaturwissenschaft
Year: 2016

description: The article chooses an unusual perspective on the Arab Spring by analyzing Algerian literature. Unlike its neighbouring countries, Algeria was not largely effected by the revolutionary changes in 2011. However, the country has a revolutionary past: it had its own “Algerian spring” in 1988, followed by a civil war in the 1990’s. This time gap allowed literature to reflect upon the consequences of such massive political and social changes. The article analyses two different literary approaches of this period of Algerian history – a novel and an essay – from well-known Algerian writers, Maїssa Bey and Boualem Sansal, with the intention to shed light upon the current developments within the region. The consequences of the Algerian civil war have been a social and political taboo for a long time. To include the topic in political or academic discussions, intellectuals recognized and emphasized the importance of literary works. In this context the article points out two literary functions: literature as a medium for cultural and collective memories and the literary potential to extend past the national and cultural boundaries in order to develop timeless and transcultural significance.

description: This paper presents a novel set of algorithms for heap abstraction, identifying logically related regions of the heap. The targeted regions include objects that are part of the same component structure (recursive data structure). The result of the technique outlined in this paper has the form of a compact normal form (an abstract model) that boosts the efficiency of the static analysis via speeding its convergence. The result of heap abstraction, together with some properties of data structures, can be used to enable program optimizations like static deallocation, pool allocation, region-based garbage collection, and object co-location. More precisely, this paper proposes algorithms for abstracting heap components with the layout of a singly linked list, a binary tree, a cycle, and a directed acyclic graph. The termination and correctness of these algorithms are studied in the paper. Towards presenting the algorithms the paper also presents concrete and abstract models for heap representations.

Выявлено, что при отсутствии обработки поч-вы растения сои запаздывают в росте и соответственно площадь листовой поверхности меньше в фазе ветвления, что связано с меньшей температурой почвы, чем по рекомендо-ванной технологии, однако к моменту цветения показатели листовой поверхности вырав-ниваются по обеим технологиям возделывания. Минеральные удобрения, внесённые сов-местно с семенами при посеве отрицательно повлияли на всхожесть и соответственно гу-стоту стояния по обеим технологиям, поэтому площадь листьев максимальной была без внесения минеральных удобрений.
description: The article presents the features of photosynthetic activity of soybean crops in the cultivation of No-till technology with different doses of mineral fertilizers in comparison with the previously recommended technology. It was revealed that in the absence of tillage soybean plants lag in growth and, accordingly, the leaf surface area is less in the branching phase, which is associated with lower soil temperature than the recommended technology, but by the time of flowering leaf surface indicators are aligned on both cultivation technologies. Mineral fertilizers introduced to-gether with seeds during sowing had a negative impact on germination and, accordingly, the density of standing on both technologies, so the maximum leaf area was without mineral ferti-lizers.

Different sequences prepared by all the available empirical data for low-lying energy levels of even and odd-mass nuclei in the 34 < A < 206 mass region. A deviation to more regular dynamics is apparent for even-mass nuclei in compare to odd-mass ones, and there are suggestions of effects due to unclosed proton shells on more chaotic dynamics.

description: We present a new methodology for studying non-Hamiltonian nonlinear systems based on an information theoretic extension of a renormalization group technique using a modified maximum entropy principle. We obtain a rigorous dimensionally reduced description for such systems. The neglected degrees of freedom by this reduction are replaced by a systematically deefined stochastic process under a constraint on the second moment. This then forms the basis of a computationally efficient method. Numerical computations for the generalized Kuramoto-Sivashinsky equation sup- port our method and reveal that the long-time underlying stochastic process of the fast (unresolved) modes obeys a universal distribution which does not depend on the initial conditions and which we rigorously derive by the maximum entropy principle.

description: Представлены результаты исследований о влиянии сроков сева на влагообеспеченность и урожайность подсолнечника, возделываемого без обработки почвы в зоне неустойчивого увлажнения Ставропольского края. Установлено, что в засушливых условиях 2018 г. бо-лее благоприятные водные условия сложились в посевах подсолнечника, посеянного в пе-риод с 25 по 30 апреля, но более эффективно почвенную влагу использовали посевы вто-рой декады мая, которые сформировали большую вегетативную массу и урожайность.
description: The article presents the results of studies on the impact of sowing time on water availability and yield of sunflower cultivated without tillage in the zone of unstable moisture of the Stavropol region. It is established that in arid conditions of 2018 more favorable water conditions were formed in the crops of sunflower sown in the period from 25 to 30 April. However, sunflower plants of the second decade of may used the moisture available in the soil more productively, and therefore formed a large vegetative mass and, consequently, yield.

description: В настоящей работе представлены материалы по влиянию стимуляторов роста растений и микроудобрений на фотосинтетическую деятельность клевера гибридного первого года жизни. При этом исходили из положения, что физиологическое состояние растений перво-го года жизни в значительной мере определяет их семенную продуктивность. Наилучшие результаты отмечены при некорневой подкормке препаратами биологического происхож-дения Агропон С и Регоплант, которые повышали площадь листовой поверхности и фото-синтетический потенциал суммарной листовой поверхности.
description: This paper presents materials on the effect of plant growth stimulants and micronutrients on the photosynthetic activity of a hybrid clover of the first year of life. At the same time, they pro-ceeded from the position that the physiological state of plants in the first year of life largely de-termines their seed productivity. The best results were observed with foliar nutrition with prepa-rations of biological origin Agropon C and Regoplant, which increased the leaf surface area and the photosynthetic potential of the total leaf surface.
The paradox of soft singularity crossing avoided by distributional cosmological quantities

description: A flat Friedmann universe filled with a mixture of anti-Chaplygin gas and dust-like matter evolves into a future soft singularity, where despite infinite tidal forces the geodesics can be continued. In the singularity the pressure of the anti-Chaplygin gas diverges, while its energy density is zero. The dust energy density however does not vanish, neither does the Hubble parameter, which implies further expansion, if its evolution is to be continuous. If so, the energy density and the pressure of the anti-Chaplygin gas would become ill-defined, hence only a contraction would be allowed. Paradoxically, the universe in this cosmological model would have to expand and contract simultaneously. The paradox can be avoided by redefining the anti-Chaplygin gas in a distributional sense. Then the Hubble parameter could be mirrored to have a jump at the singularity, allowing for a subsequent contraction. With this modification the set of Friedmann, Raychaudhuri and continuity equations are all obeyed both at the singularity and in its vicinity.

description: We prove that the expected value and median of the supremum of $L^2$ normalized random holomorphic fields of degree $n$ on $m$-dimensional Kähler manifolds are asymptotically of order $\sqrt{m\log n}$. This improves the prior result of Shiffman-Zelditch (arXiv:math/0303335) that the upper bound of the media is of order $\sqrt{\log n}$ The estimates are based on the entropy methods of Dudley and Sudakov combined with a precise analysis of the relevant pseudo-metric and its covering numbers, which can be precisely evaluated using off-diagonal asymptotics of Bergman kernels. Recent work of the authors on the value distribution of these fields are also used to get precise constants.

description: We demonstrate Optical-Resolution Photoacoustic Microscopy (OR-PAM), where the optical field is focused and scanned using Digital Phase Conjugation (DPC) through a multimode fiber. The focus is scanned across the field of view using digital means, and the acoustic signal induced is collected by a transducer. Optical-resolution photoacoustic images of a knot made by two absorptive wires are obtained and we report on resolution smaller than 1.5μm across a 201μm by 201μm field of view. The use of a multimode optical fiber for the optical excitation part can pave the way for miniature endoscopes that can provide optical-resolution photoacoustic images at large optical depth.

description: The following electromagnetism (EM) inverse problem is addressed. It consists in estimating local radioelectric properties of materials recovering an object from global EM scattering measurements, at various incidences and wave frequencies. This large scale ill-posed inverse problem is explored by an intensive exploitation of an efficient 2D Maxwell solver, distributed on high performance computing machines. Applied to a large training data set, a statistical analysis reduces the problem to a simpler probabilistic metamodel, on which Bayesian inference can be performed. Considering the radioelectric properties as a hidden dynamic stochastic process, that evolves in function of the frequency, it is shown how advanced Markov Chain Monte Carlo methods, called Sequential Monte Carlo (SMC) or interacting particles, can take benefit of the structure and provide local EM property estimates.

Quantum dynamics of a nano-rod under compression

description: A nano-rod under compression, which is capacitively coupled to a Cooper-pair box, can be modeled in terms of a quartic oscillator linearly interacting with a tunnelling pseudo-spin. We have integrated numerically the quantum dynamics of this system in the partial Wigner representation and calculated the pseudo-spin population difference. Depending on the coupling, we have verified that the quantum tunnelling of the oscillator can lead to a more effective reduction of the Rabi oscillation amplitude of the pseudo-spin. Such findings suggests an experimental set-up that might be able to discriminate between the quantum and the classical motion of a nano-rod.
