description: The rate of electron-positron pair production in linearly polarized counter-propagating lasers is evaluated from a recently discovered solution of the time-dependent Dirac equation. The latter is solved in momentum space where it is formally equivalent to the Schrödinger equation describing a strongly driven two-level system. The solution is found from a simple transformation of the Dirac equation and is given in compact form in terms of the doubly-confluent Heun's function. By using the analogy with the two-level system, it is shown that for high-intensity lasers, pair production occurs through periodic non-adiabatic transitions when the adiabatic energy gap is minimal. These transitions give rise to an intricate interference pattern in the pair spectrum, reminiscent of the Landau-Zener-Stückelberg phenomenon in molecular physics: the accumulated phase result in constructive or destructive interference. The adiabatic-impulse model is used to study this phenomenon and shows an excellent agreement with the exact result.

description: High-resolution vehicle headlamps are the technological way to intelligently illuminate the traffic area to increase safety and comfort. For the technical realization of these headlamps, different technologies come into question, which are the subject of intensive research at universities and among the manufacturers. We present an overview of the possible technologies and analyze their potential for use in high-resolution headlamps. Furthermore, we explain how the design of the optical system for the different technologies can be made. Another part of this paper is the comparison of published prototypes of high-resolution headlamps and the compilation of key properties.
Casimir-Polder Forces between Chiral Objects

description: The chiral component of the Casimir-Polder potential is derived within the framework of macroscopic quantum electrodynamics. It is shown to exist only if the particle and the medium are both chiral. Furthermore, the chiral component of the Casimir-Polder potential can be attractive or repulsive, depending on the chirality of the molecule and the medium. The theory is applied to a cavity geometry in the non-retarded limit with the intention of enantiomer separation. For a ground state molecule the chiral component is dominated by the electric component and thus no explicit separation will happen. If the molecule is initially in an excited state the electric component of the Casimir-Polder force can be suppressed by an appropriate choice of material and the chiral component can select the molecule based on its chirality, allowing enantiomeric separation to occur.

description: We present an almost fully analytical technique for computing Casimir interactions between periodic lamellar gratings based on a modal approach. Our method improves on previous work on Casimir modal approaches for nanostructures by using the exact form of the eigenvectors of such structures, and computing eigenvalues by solving numerically a simple transcendental equation. In some cases eigenvalues can be solved for exactly, such as the zero frequency limit of gratings modeled by a Drude permittivity. Our technique also allows us to predict analytically the behavior of the Casimir interaction in limiting cases, such as the large separation asymptotics. The method can be generalized to more complex grating structures, and may provide a deeper understanding of the geometry-composition-temperature interplay in Casimir forces between nanostructures.

description: This paper contributes to the development of collostructional analysis by taking up one of the long-standing issues in collostructional analysis, viz. the assessment and interpretation of the collexeme lists created. It uses the DWDS corpus documenting 20th century written German to study two modalverb constructions which contain either vermögen or bekommen as the first verb plus an infinitive. When expressing ‘possibility’/‘capability’, these constructions compete with the ubiquitous and strongly grammaticalized könnenconstruction. To compare their constructional semantics, the paper combines collostructional analyses with a close investigation of the verbal meanings characterizing their Vinf slots. To classify the collexemes occurring in these slots comprehensively, the semantic information provided about each Vinf collexeme by “GermaNet” is utilized in three different ways: A manual, context-sensitive classification of the top collexemes into the 15 generic verb classes provided by GermaNet is followed by cluster analyses over the semantic-relatedness values given out by the SemRel tool of GermaNet for the pairwise comparison of all possible collexeme combinations. This is complemented by a network analysis identifying collexemes that are salient or “central”, i.e. located on the largest number of “shortest paths” connecting any two collexemes. The implications of the results for the functional differential between the two constructions as well as the methodology itself are discussed.

description: We present the most energetic BALQSO outflow measured to date, with a kinetic luminosity of at least 10^46 ergs/s, which is 5% of the bolometric luminosity of this high Eddington ratio quasar. The associated mass flow rate is 400 solar masses per year. Such kinetic luminosity and mass flow rate should provide strong AGN feedback effects. The outflow is located at about 300 pc from the quasar and has a velocity of roughly 8000 km/s. Our distance and energetic measurements are based in large part on the identification and measurement of SIV and SIV* BALs. The use of this high ionization species allows us to generalize the result to the majority of high ionization BALQSOs that are identified by their CIV absorption. We also report the energetics of two other outflows seen in another object using the same technique. The distances of all 3 outflows from the central source (100-2000pc) suggest that we observe BAL troughs much farther away from the central source than the assumed acceleration region of these outflows (0.01-0.1pc).

We also discuss research challenges for supporting sophisticated issues using our experience with DSMCTL, the Database of Government Officials of the Republic of China, and the Dream of the Red Chamber. Advanced techniques and tools for lexical, syntactic, semantic, and pragmatic processing of language information, along with more thorough data collection, are needed to strengthen the collaboration between historians and computer scientists.

description: Sulfurtransferases/rhodaneses (Str) are enzymes widely distributed in archaea, prokaryota and eukaryota, and catalyze the transfer of sulfur from a donor molecule to a thiophilic acceptor substrate. In this reaction, Str cycles between the sulfur-free and the sulfur-substituted form. Two-domain Str consist of two globular domains of nearly identical size and conformation connected by a short linker sequence, which is elongated in plant two-domain Str proteins compared to Str in other organisms. The two-domain Arabidopsis thaliana Str1 protein (At1g 79230) was expressed in Escherichia coli as a mature protein, as a variant without the elongated linker sequence, and as AtStr1C332S and AtStr1C339V. The persulfuration state of the purified recombinant proteins was investigated in the presence and absence of sulfur donors by fluorescence spectroscopy. The secondary structure was analyzed by circular dichroism (CD) in the far-UV range, while overall changes in tertiary structure were determined by CD in the near-UV range. Finally, protein stability was analyzed by tryptic digestion. The elongated linker sequence is essential for correct conformation and stability, and thereby affects the catalytic activity of AtStr1. Replacement of the catalytic cysteine residue C332 leads to higher rigidity of the molecule, whereas replacement of C339 does not lead to any conformational changes, providing evidence of the direct involvement of C339 in catalysis.

description: Understanding the origin of AGN absorption line profiles and their diversity could help to explain the physical structure of the accretion flow, and also to assess the impact of accretion on the evolution of the AGN host galaxies. Here we present our first attempt to systematically address the issue of the origin of the complexities observed in absorption profiles. Using a simple method, we compute absorption line profiles against a continuum point source for several simulations of accretion disk winds. We investigate the geometrical, ionization, and dynamical effects on the absorption line shapes. We find that significant complexity and diversity of the absorption line profile shapes can be produced by the non-monotonic distribution of the wind velocity, density, and ionization state. Non-monotonic distributions of such quantities are present even in steady-state, smooth disk winds, and naturally lead to the formation of multiple and detached absorption troughs. These results demonstrate that the part of a wind where an absorption line is formed is not representative of the entire wind. Thus, the information contained in the absorption line is incomplete if not even insufficient to well estimate gross properties of the wind such as the total mass and energy fluxes. In addition, the highly dynamical nature of certain portions of disk winds can have important effects on the estimates of the wind properties. For example, the mass outflow rates can be off up to two orders of magnitude with respect to estimates based on a spherically symmetric, homogeneous, constant velocity wind.

description: In this contribution we present an intrinsic description of time-variant Port Hamiltonian systems as they appear in modeling and control theory. This formulation is based on the splitting of the state bundle and the use of appropriate covariant derivatives, which guarantees that the structure of the equations is invariant with respect to time-variant coordinate transformations. In particular, we will interpret our covariant system representation in the context of control theoretic problems. Typical examples are time-variant error systems related to trajectory tracking problems which allow for a Hamiltonian formulation. Furthermore we will analyze the concept of collocation and the balancing/interaction of power flows in an intrinsic fashion.

description: Infectious diseases outbreaks are often characterized by a spatial component induced by hosts' distribution, mobility, and interactions. Spatial models that incorporate hosts' movements are being used to describe these processes, to investigate the conditions for propagation, and to predict the spatial spread. Several assumptions are being considered to model hosts' movements, ranging from permanent movements to daily commuting, where the time spent at destination is either infinite or assumes a homogeneous fixed value, respectively. Prompted by empirical evidence, here we introduce a general metapopulation approach to model the disease dynamics in a spatially structured population where the mobility process is characterized by a heterogeneous length of stay. We show that large fluctuations of the length of stay, as observed in reality, can have a significant impact on the threshold conditions for the global epidemic invasion, thus altering model predictions based on simple assumptions, and displaying important public health implications.

description: How can the information that a set ${X_{1},...,X_{n}}$ of random variables contains about another random variable $S$ be decomposed? To what extent do different subgroups provide the same, i.e. shared or redundant, information, carry unique information or interact for the emergence of synergistic information? Recently Williams and Beer proposed such a decomposition based on natural properties for shared information. While these properties fix the structure of the decomposition, they do not uniquely specify the values of the different terms. Therefore, we investigate additional properties such as strong symmetry and left monotonicity. We find that strong symmetry is incompatible with the properties proposed by Williams and Beer. Although left monotonicity is a very natural property for an information measure it is not fulfilled by any of the proposed measures. We also study a geometric framework for information decompositions and ask whether it is possible to represent shared information by a family of posterior distributions. Finally, we draw connections to the notions of shared knowledge and common knowledge in game theory. While many people believe that independent variables cannot share information, we show that in game theory independent agents can have shared knowledge, but not common knowledge. We conclude that intuition and heuristic arguments do not suffice when arguing about information.

description: When studying how human beings can make something that is absent present through signs, semioticians have mainly focused on the way human beings make the past present. In this monographic section of the journal, we offer a reflection on ways of making the future present. Our approach to temporality is relational and evenemential: to study semiotic forms in the representation of the future means to investigate its modes of existence and its relationship with past and present events. We will introduce the topic by illustrating, first, the evenemential and relational approach to the study of temporality; second, we will outline a semiotic approach to the analysis of the future as a time of history, drawing on the epistemological reflections of Charles Sanders Peirce and Jurij Lotman; third, we will offer an example and a general reflection on regimes of temporality and historicity in texts. We will conclude by giving an overview of the contributions we have the honour to include in this monographic section.

Simulations now cover a wide range of phenomena, from whole active regions, over individual sunspots and pores, magnetic flux concentrations and vortices in intergranular lanes, down to the intricate mixed-polarity structure of the magnetic field generated by small-scale dynamo action. The simulations in concert with high-resolution observations have provided breakthroughs in our understanding of the structure and dynamics of the magnetic fields in the solar photosphere.

Mixed state Pauli channel parameter estimation

Publisher: name: arXiv
Year: 2012
Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: The accuracy of any physical scheme used to estimate the parameter describing the strength of a single qubit Pauli channel can be quantified using standard techniques from quantum estimation theory. It is known that the optimal estimation scheme, with m channel invocations, uses initial states for the systems which are pure and unentangled and provides an uncertainty of O[1/m^(1/2)]. This protocol is analogous to a classical repetition and averaging scheme. We consider estimation schemes where the initial states available are not pure and compare a protocol involving quantum correlated states to independent state protocols analogous to classical repetition schemes. We show, that unlike the pure state case, the quantum correlated state protocol can yield greater estimation accuracy than any independent state protocol. We show that these gains persist even when the system states are separable and, in some cases, when quantum discord is absent after channel invocation. We describe the relevance of these protocols to nuclear magnetic resonance measurements.

description: The assessment of the probability of assimilating the material of an academic discipline by a student was carried out using an integral distribution function (probability) obtained by integrating a differential distribution function (probability density), which, in turn, was obtained by averaging individual distribution functions identifying students in the process of assimilating information. The differential distribution function defines the probability of finding a student in a single area of the information space, which is equivalent to the probability of the student's assimilation of information in this area of the information space. It has a U-shaped appearance due to the presence of the measurement scale boundaries. The integral distribution function calculated in a dimensionless coordinate system is in fact universal. It allows directly, knowing student’s knowledge assessment score obtained on any point scale, to determine for the probability of assimilating the material of the academic discipline by him.

description: High cadence, multi-wavelength observations and simulations are employed for the analysis of solar photospheric magnetic bright points (MBPs) in the quiet Sun. The observations were obtained with the Rapid Oscillations in the Solar Atmosphere (ROSA) imager and the Interferometric BIdimensional Spectrometer (IBIS) at the Dunn Solar Telescope. Our analysis reveals that photospheric MBPs have an average transverse velocity of approximately 1 km/s, whereas their chromospheric counterparts have a slightly higher average velocity of 1.4 km/s. Additionally, chromospheric MBPs were found to be around 63% larger than the equivalent photospheric MBPs. These velocity values were compared with the output of numerical simulations generated using the MURaM code. The simulated results were similar, but slightly elevated, when compared to the observed data. An average velocity of 1.3 km/s was found in the simulated G-band images and an average of 1.8 km/s seen in the velocity domain at a height of 500 km above the continuum formation layer. Delays in the change of velocities were also analysed. Average delays of ~4 s between layers of the simulated data set were established and values of ~29 s observed between G-band and Ca II K ROSA observations. The delays in the simulations are likely to be the result of oblique granular shock waves, whereas those found in the observations are possibly the result of a semi-rigid flux tube.

description: Paragnetina media (Walker). With the exception of the southernmost U.S. states, this coolwater species is distributed throughout much of eastern North America (Stark & Szczytko 1981; Stark 2004). It is known historically from Illinois only as a single nymph collected from the Mississippi River in Carroll County in 1932 (Frison 1935). DeWalt et al. (2005) listed is it as extirpated from Illinois. Grubbs (2004) reported that no specimens or literature references were found for this species in Indiana, but stated that populations may be found in the northern tier counties of the state. We present two records from northern Indiana. IN, Elkhart Co., Little Elkhart River, 4 mi E Bristol, Bonneyville Mill County Preserve, 41.7188, -85.7649, 6/27/2006, R.E.

description: Multiple interlinked positive feedback loops shape the stimulus responses of various biochemical systems, such as the cell cycle or intracellular calcium release. Recent studies with simplified models have identified two advantages of coupling fast and slow feedback loops. Namely, this dual-time structure enables a fast response while enhancing resistances of responses and bistability to stimulus noise. We now find that in addition: 1) the dual-time structure confers resistance to internal noise due to molecule number fluctuations, and 2) model variants with altered coupling, which better represent some specific systems, share all the above advantages. We develop a similar bistable model with a fast autoactivation loop coupled to a slow loop, which minimally represents positive feedback that may be essential for long-term synaptic potentiation (LTP). The advantages of fast response and noise resistance carry over to this model. Empirically, LTP develops resistance to reversal over ~1 h. The model suggests this resistance may result from increased amounts of synaptic kinases involved in positive feedback.

description: Der Beitrag zeigt die vielfältigen Verflechtungen von Kunst und Architektur auf, die sowohl von Analogien und Überlagerungen als auch von Differenzen geprägt sind. Der Blick auf künstlerische Konzepte der Architektur der Gegenwart sowie Schnittstellenkonventionen und Bewegungen der Vergangenheit schaut über das gebaute Objekt hinaus auf mediale Produktionen, Wahrnehmungsweisen und Denkformen, die alternative Perspektiven anbieten und mit Konventionen brechen.
description: The article shows the diverse interweaving of art and architecture, which are characterized by analogies and overlays as well as differences. The look at artistic concepts of the architecture of the present as well as interface conventions and movements of the past looks beyond the built object to media productions, modes of perception and ways of thinking that offer alternative perspectives and break with conventions.

description: Thin viscous liquid films driven by capillarity are well described in the lubrication theory through the thin film equation. In this article, we present an analytical solution of this equation for a particular initial profile: a stepped perturbation. This initial condition allows a linearization of the problem making it amenable to Fourier analysis. The solution is obtained and characterized. As for a temperature step in the heat equation, self-similarity of the first kind of the full evolution is demonstrated and a long-term expression for the excess free energy is derived. In addition, hydrodynamical fields are described. The solution is then compared to experimental profiles from a model system: a polystyrene nanostep above the glass transition temperature which flows due to capillarity. The excellent agreement enables a precise measurement of the capillary velocity for this polymeric liquid, without involving any numerical simulation. More generally, as these results hold for any viscous system driven by capillarity, the present solution may provide a useful tool in hydrodynamics of thin viscous films.

description: Purpose: The purpose of this paper is to examine quadratic convergence of finite element analysis for hyperelastic material at finite strains via Abaqus-UMAT as well as classification of the rates of convergence for iterative solutions in regular cases. Design/methodology/approach: Different formulations for stiffness - Hessian form of the free energy functionals - are systematically given for getting the rate-independent analytical tangent and the numerical tangent as well as rate-dependent tangents using the objective Jaumann rate of Kirchoff stress tensor as used in Abaqus. The convergence rates for available element types in Abaqus are computed and compared for simple but significant nonlinear elastic problems, such as using the 8-node linear brick (B-bar) element - also with hybrid pressure formulation and with incompatible modes - further the 20-node quadratic brick element with corresponding modifications as well as the 6-node linear triangular prism element and 4-node linear tetrahedral element with modifications. Findings: By using the Jaumann rate of Kirchoff stress tensor for both, rate dependent and rate independent problems, quadratic or nearly quadratic convergence is achieved for most of the used elements using Abaqus-UMAT interface. But in case of using rate independent analytical tangent for rate independent problems, even convergence at all is not assured for all elements and the considered problems. Originality/value: First time the convergence properties of 3D finite elements available in Abaqus sre systematically treated for elastic material at finite strain via Abaqus-UMAT. © Emerald Group Publishing Limited.

description: A Large Quasar Group (LQG) of particularly large size and high membership has been identified in the DR7QSO catalogue of the Sloan Digital Sky Survey. It has characteristic size (volume^1/3) ~ 500 Mpc (proper size, present epoch), longest dimension ~ 1240 Mpc, membership of 73 quasars, and mean redshift = 1.27. In terms of both size and membership it is the most extreme LQG found in the DR7QSO catalogue for the redshift range 1.0 <= z <= 1.8 of our current investigation. Its location on the sky is ~ 8.8 deg north (~ 615 Mpc projected) of the Clowes & Campusano LQG at the same redshift, = 1.28, which is itself one of the more extreme examples. Their boundaries approach to within ~ 2 deg (~ 140 Mpc projected). This new, huge LQG appears to be the largest structure currently known in the early universe. Its size suggests incompatibility with the Yadav et al. scale of homogeneity for the concordance cosmology, and thus challenges the assumption of the cosmological principle.

description: Purpose: The authors' research was carried out with the aim of analyzing perception of luxury and luxury brands among an international sample of young people. Design/methodology/approach: This article was based on an empirical study among 233 respondents. First, a qualitative analysis of content using the respondents' own words was conducted. Then, to show whether there are differences between countries and significant groups of countries, an analysis of variance (one-way ANOVA) was performed and analyzed with Fisher F-test and post-hoc Duncan tests. Findings: Beyond the belief in the existence of two stable groups of developed and developing countries with regard to luxury, this study shows a situation that requires further analysis. The main results show some strong cross-cultural differences in the perception of luxury, which is multi-faceted as demonstrated by previous studies in this field. Research limitations/implications: Results of this exploratory study confirm that the concept of luxury presents multiple facets, and the authors' analysis provides an in-depth survey of the main categories and attributes that can be used to describe this concept. Although this study was only exploratory in nature, a number of comments can be made to highlight the congruence between the concept of luxury for young people and recent academic literature. Practical implications: To maintain their brand equity, companies in the luxury sector seek to improve their image within younger targets. Managerial implications of the authors' research indicate that international luxury companies should take into consideration the multi-faceted concept of luxury in general, but also the main differences between countries in the continuum between the "status" and "emotional" dimensions of luxury. According to the authors' research, luxury companies cannot adopt a global strategy when addressing the six countries analyzed. Some managerial recommendations are developed in this perspective. Originality/value: The additional value of this article stems from its reliance on a cross-cultural in-depth study between six countries (Italy, France, Germany, China, Japan, and USA). The balance between qualitative and quantitative techniques makes this article particularly relevant when drawing both conceptual and managerial conclusions. © Emerald Group Publishing Limited.
