Spectroscopic factor of the 1+, 25Al(p,g)26Si resonance at Ex=5.68 MeV

description: Nuclear shell model predictions for the proton spectroscopic factor of the 1+, Ex = 5.68 MeV level in 26Si are about fifty times smaller than the value suggested by the measured (a,3He) cross section for the Ex = 5.69 MeV mirror level in 26Mg, assuming purely single-particle transfer. Given that the 5.69 MeV level has been very weakly, if it all, populated in previous studies of the simpler 25Mg(d,p) reaction, it is unclear if the (a,3He) result is a true single-particle spectroscopic factor. If we assume the (a,3He) result, the thermonuclear rate of the 25Al(p,g)26Si reaction would increase by factors of 6 - 50 over stellar temperatures of T = 0.05 - 0.2 GK. We examine the implications of this enhanced rate for model predictions of nucleosynthesis in classical nova explosions.

description: We discuss some inequalities for N nonnegative numbers.

The inequalities characterize the degree of quantum correlations in addition to noncontextuality and quantum discord. We use the subadditivity and strong subadditivity conditions for qudit tomographic-probability distributions depending on the unitary-group parameters in order to derive new inequalities for Shannon, Renyi, and Tsallis entropies of spin states.

Process Model Difference Analysis for Supporting Process Evolution

Subjects: subject: Software Engineering (cs.SE)
subject: FOS: Computer and information sciences

description: Software development processes are subject to variations in time and space, variations that can originate from learning effects, differences in application domains, or a number of other causes. Identifying and analyzing such differences is crucial for a variety of process activities, like defining and evolving process standards, or analyzing the compliance of process models to existing standards, among others. In this paper, we show why appropriately identifying, describing, and visualizing differences between process models in order to support such activities is a highly challenging task. We present scenarios that motivate the need for process model difference analysis, and describe the conceptual and technical challenges arising from them. In addition, we sketch an initial tool-based approach implementing difference analysis, and contrast it with similar existing approaches. The results from this paper constitute the requirements for our ongoing development effort, whose objectives we also describe briefly.

description: Previous radio observations of the galaxy cluster A3560 in the Shapley Concentration showed complex radio emission associated with the brightest cluster member.To understand its origin we observed it with the GMRT, the VLA and ATCA at 240 and 610 MHz, 1.28,1.4, 2.3,4.8 and 8.4 GHz, and performed a detailed morphological and spectral study of the radio emission associated with the BCG. We also observed the cluster with XMM-Newton and Chandra to derive the properties of the ICM. The radio emission of the N-E nucleus of the dumb-bell BCG shows an active radio galaxy, plus aged diffuse emission, which is not refurbished at present. Our Chandra data show that the radio active nucleus of the BCG has extended X-ray emission, which we classify as a low-luminosity corona. A residual image of the XMM-Newton brightness shows the presence of a spiral-like feature, which we interpret as the signature of gas sloshing. The presence of a subgroup is clear in the surface brightness residual map, and in the XMM-Newton temperature analysis. The optical 2D analysis shows substructure in A3560. A galaxy clump was found at the location of the X-ray subgroup, and another group is present south of the cluster core, close to the spiral-like feature. The aged part of the radio emission closely follows the spiral pattern of the X-ray residual brightness distribution, while the two active radio lobes are bent in a completely different direction. We conclude that the complex radio emission associated with the cluster BCG is the result of a minor merger event in A3560. The aged diffuse emission is strongly affected by the sloshing motion in the ICM. On the other hand, the bent jets and lobes of the current radio AGN activity may reflect a complex gas velocity field in the innermost cluster regions and/or sloshing-induced oscillations in the motion of the cD galaxy.

description: We consider particle production in high energy pA collisions. In addition to the coherent interactions with the nuclear color field, we take into account coherent interactions with the nuclear electromagnetic Coulomb field. Employing the dipole model, we sum up the leading multiple color and electromagnetic interactions and derive inclusive cross sections for photon and dilepton production. We found that the Coulomb corrections are up to $10\%$ at $\sqrt{s}=200$~GeV per nucleon.

description: We investigate the effect of hydrogen coverage on the optical conductivity of single-side hydrogenated graphene from first principles calculations. To account for different degrees of uniform hydrogen coverage we calculate the complex optical conductivity for graphene supercells of various sizes, each containing a single additional hydrogen atom. We use the linearized augmented plane wave (LAPW) method, as implemented in the WIEN2k density functional theory code, to show that the hydrogen coverage strongly influences the complex optical conductivity and thus the optical properties, such as absorption, of hydrogenated graphene. We find that the optical conductivity of graphene in the infrared, visible, and ultraviolet range has different characteristic features depending on the degree of hydrogen coverage. This opens up new possibilities to tailor the optical properties of graphene by reversible hydrogenation, and to determine the hydrogen coverage of hydrogenated graphene samples in the experiment by contact-free optical absorption measurements.

description: A simple model for simulating flows of active suspensions is investigated. The approach is based on dissipative particle dynamics. While the model is potentially applicable to a wide range of self-propelled particle systems, the specific class of self-motile bacterial suspensions is considered as a modeling scenario. To mimic the rod-like geometry of a bacterium, two dissipative particle dynamics particles are connected by a stiff harmonic spring to form an aggregate dissipative particle dynamics molecule. Bacterial motility is modeled through a constant self-propulsion force applied along the axis of each such aggregate molecule. The model accounts for hydrodynamic interactions between self-propelled agents through the pairwise dissipative interactions conventional to dissipative particle dynamics. Numerical simulations are performed using a customized version of the open-source LAMMPS (Large-scale Atomic/Molecular Massively Parallel Simulator) software package. Detailed studies of the influence of agent concentration, pairwise dissipative interactions, and Stokes friction on the statistics of the system are provided. The simulations are used to explore the influence of hydrodynamic interactions in active suspensions. For high agent concentrations in combination with dominating pairwise dissipative forces, strongly correlated motion patterns and a fluid-like spectral distributions of kinetic energy are found. In contrast, systems dominated by Stokes friction exhibit weaker spatial correlations of the velocity field. These results indicate that hydrodynamic interactions may play an important role in the formation of spatially extended structures in active suspensions.

description: It is shown that each quadrangulation of the 2-torus by the Cartesian product of two cycles can be geometrically realized in (Euclidean) 4-space without hidden symmetries---that is, so that each combinatorial cellular automorphism of the quadrangulation extends to a geometric symmetry of its Euclidean realization. Such realizations turn out to be new regular toroidal geometric 2-polyhedra which are inscribed in the Clifford 2-torus in 4-space, just as the five regular spherical 2-polyhedra are inscribed in the 2-sphere in 3-space. The following are two open problems: Realize geometrically (1) the regular triangulations and (2) the regular hexagonizations of the 2-torus without hidden symmetries in 4-space.

We show that these elementary excitations are modified Bogoliubov oscillations, or phonons with an helical wave structure. These twisted phonon modes can contribute to the total vorticity in a quantum fluid, thus complementing the contribution of the traditional quantum vortices. Linear and nonlinear versions of twisted phonon modes will be discussed. New envelope soliton solutions are shown to exist in a condensate.

description: This work examines infalling matter following an enormous Coronal Mass Ejection (CME) on 2011 June 7. The material formed discrete concentrations, or blobs, in the corona and fell back to the surface, appearing as dark clouds against the bright corona. In this work we examined the density and dynamic evolution of these blobs in order to formally assess the intriguing morphology displayed throughout their descent. The blobs were studied in five wavelengths (94, 131, 171, 193 and 211 Å) using the Solar Dynamics Observatory Atmospheric Imaging Assembly (SDO/AIA), comparing background emission to attenuated emission as a function of wavelength to calculate column densities across the descent of four separate blobs. We found the material to have a column density of hydrogen of approximately 2 $\times$ 10$^{19}$ cm$^{-2}$, which is comparable with typical pre-eruption filament column densities. Repeated splitting of the returning material is seen in a manner consistent with the Rayleigh-Taylor instability. Furthermore, the observed distribution of density and its evolution are also a signature of this instability. By approximating the three-dimensional geometry (with data from STEREO-A), volumetric densities were found to be approximately 2 $\times$ 10$^{-14}$ g cm$^{-3}$, and this, along with observed dominant length-scales of the instability, was used to infer a magnetic field of the order 1 G associated with the descending blobs.

description: This research aims to determine whether Generation Z are using the GIF as a method of culture preservation. To do this, 10 of the most popular GIF’s from the 2003 film Mean Girls, have been analysed. The analysis is focused on two aspects, the first being the content of the GIF itself, namely the phrase used, or what is visible within the frame. The second aspect is the wider culture context of the GIF, meaning that aspects of society such as recreations of the film, songs that feature lyrics from Mean Girls and examples of items for sale that replicate items used within the film, have also been analysed. This two part analysis is based on the factors determined in the literature review, and these aspects of the research are used to conclude that Generation Z is using the GIF to preserve this particular aspect of popular culture, but not in a conscious manor. Factors such as nostalgia, collective memory and the richness of a GIF itself can be suggested as the factors as to both why Generation Z is preserving culture in this way and why they have chosen this particular subject matter to preserve. However, while this research provides a solid basis into this topic further research is required to prove the extent as to which culture is being preserved in this way.

Για να γίνει αυτό, αναλύθηκαν 10 από τα πιο δημοφιλή GIF από την ταινία Mean Girls του 2003. Η ανάλυση επικεντρώνεται σε δύο πτυχές, η πρώτη είναι το περιεχόμενο του ίδιου του GIF, δηλαδή η φράση που χρησιμοποιείται ή αυτό που είναι ορατό μέσα στο πλαίσιο. Η δεύτερη πτυχή είναι το ευρύτερο πολιτισμικό πλαίσιο του GIF, πράγμα που σημαίνει ότι έχουν αναλυθεί κοινωνικές πτυχές, όπως διασκευές της ταινίας, τραγούδια με στίχους από Mean Girls και παραδείγματα αντικειμένων προς πώληση που αντιγράφουν αντικείμενα που χρησιμοποιούνται στην ταινία. Αυτή η ανάλυση δύο μερών βασίζεται στους παράγοντες που προσδιορίζονται στην ανασκόπηση της βιβλιογραφίας, και αυτές οι πτυχές της έρευνας μας οδηγούν στο συμπέρασμα ότι η Generation Z χρησιμοποιεί το GIF για να διατηρήσει τη συγκεκριμένη πτυχή της λαϊκής κουλτούρας. Παράγοντες όπως η νοσταλγία, η συλλογική μνήμη και ο πλούτος του ίδιου του GIF μπορούν να εξηγήσουν το γιατί η Generation Z διατηρεί τον πολιτισμό με αυτόν τον τρόπο αλλά και γιατί επέλεξε αυτό το συγκεκριμένο θέμα. Ωστόσο, αν και αυτή η έρευνα παρέχει μια σταθερή βάση κατανόησης πάνω στο θέμα, απαιτείται περαιτέρω έρευνα για να αποδειχθεί ο βαθμός στον οποίο ο πολιτισμός διατηρείται με αυτόν τον τρόπο.

description: The boxdot conjecture asserts that every normal modal logic that faithfully interprets T by the well-known boxdot translation is in fact included in T. We confirm that the conjecture is true. More generally, we present a simple semantic condition on modal logics $L_0$ which ensures that the largest logic where $L_0$ embeds faithfully by the boxdot translation is $L_0$ itself. In particular, this natural generalization of the boxdot conjecture holds for S4, S5, and KTB in place of T.

description: Stabilization of the Si(553) surface by Au adsorption results in two different atomically defined chain types, one of Au atoms and one of Si. At low temperature these chains develop two- and threefold periodicity, respectively, previously attributed to Peierls instabilities. Here we report evidence from scanning tunneling microscopy that rules out this interpretation. The x3 superstructure of the Si chains vanishes for low tunneling bias, i.e., close the Fermi level. In addition, the Au chains remain metallic despite their period doubling. Both observations are inconsistent with a Peierls mechanism. On the contrary, our results are in excellent, detailed agreement with the Si(553)-Au ground state predicted by density-functional theory, where the x2 periodicity of the Au chain is an inherent structural feature and every third Si atom is spin-polarized.

description: Using spectra obtained by the EIS instrument onboard Hinode, we present a detailed spatially resolved abundance map of an active region (AR)-coronal hole (CH) complex that covers an area of 359 arcsec x 485 arcsec. The abundance map provides first ionization potential (FIP) bias levels in various coronal structures within the large EIS field of view. Overall, FIP bias in the small, relatively young AR is 2-3. This modest FIP bias is a consequence of the AR age, its weak heating, and its partial reconnection with the surrounding CH. Plasma with a coronal composition is concentrated at AR loop footpoints, close to where fractionation is believed to take place in the chromosphere. In the AR, we found a moderate positive correlation of FIP bias with nonthermal velocity and magnetic flux density, both of which are also strongest at the AR loop footpoints. Pathways of slightly enhanced FIP bias are traced along some of the loops connecting opposite polarities within the AR. We interpret the traces of enhanced FIP bias along these loops to be the beginning of fractionated plasma mixing in the loops. Low FIP bias in a sigmoidal channel above the AR's main polarity inversion line where ongoing flux cancellation is taking place, provides new evidence of a bald patch magnetic topology of a sigmoid/flux rope configfiuration.

Allerdings sind die Zukunftsaussichten für das Überleben dieses Dialekts düster und es zeichnet sich auch das Verschwinden der neusyrischen Schriftsprache in wenigen Generationen ab. Dem Ziel, das Neusyrische nicht völlig dem Vergessen anheimfallen zu lassen, hat sich die Forschungsstelle für aramäische Studien an der Universität Heidelberg verschrieben.

Mittlerweile lassen sich immer genauer einzelne Nervenschaltkreise identifizieren, die das Zusammenspiel zwischen einem Gewebeschaden und der Struktur, der Funktion und den Eigenschaften neuronaler Bahnen sowie deren Einfluss auf Verhalten und psychisches Befinden steuern.

description: Motivated by recent interest in perovskite surfaces and heterostructures, we present an analysis of the Kubo conductivity of a two-dimensional electron gas (2DEG) formed in the $t_{2g}$ bands of an oxide with perovskite structure. We find that when the electric field is polarized in the plane of the 2DEG, the optical conductivity is dominated by nearly independent Drude contributions from two-dimensional subband Fermi surfaces, whereas for perpendicular-to-plane polarization it has strong intersubband features. Our analysis suggests that perpendicular-to-plane optical conductivity studies may help advance understanding of the interplay between lattice distortions and electron-electron interactions in complex oxide 2DEG quantum confinement physics.

description: Aims: Revealing the fragmentation, infall, and outflow processes in the immediate environment around massive young stellar objects is crucial for understanding the formation of the most massive stars. Methods: With this goal in mind we present the so far highest spatial-resolution thermal submm line and continuum observations toward the young high-mass protostar NGC7538 IRS1. Using the Plateau de Bure Interferometer in its most extended configuration at 843mum wavelength, we achieved a spatial resolution of 0.2"x0.17", corresponding to ~500AU at a distance of 2.7\,kpc. Results: For the first time, we have observed the fragmentation of the dense inner core of this region with at least three subsources within the inner 3000 AU. The outflow exhibits blue- and red-shifted emission on both sides of the central source indicating that the current orientation has to be close to the line-of-sight, which differs from other recent models. We observe rotational signatures in northeast-southwest direction; however, even on scales of 500 AU, we do not identify any Keplerian rotation signatures. This implies that during the early evolutionary stages any stable Keplerian inner disk has to be very small (<=500 AU). The high-energy line HCN(4-3)v2=1 (E_u/k=1050K) is detected over an extent of approximately 3000 AU. In addition to this, the detection of red-shifted absorption from this line toward the central dust continuum peak position allows us to estimate infall rates of ~1.8x10^(-3)Msun/yr on the smallest spatial scales. Although all that gas will not necessarily be accreted onto the central protostar, nevertheless, such inner core infall rates are among the best proxies of the actual accretion rates one can derive during the early embedded star formation phase. These data are consistent with collapse simulations and the observed high multiplicity of massive stars.

description: Die Natur befindet sich in einem kontinuierlichen Wandel, da sie sich immer wieder neu auf die Umwelt einstellt. Das hat eine unermessliche Vielfalt an Arten entstehen lassen – und Arten für immer ausgelöscht. Wie sehen die Anpassungsstrategien der Natur aus? Entwicklungsbiologen am Heidelberger „Centre for Organismal Studies“ versuchen, den Raum zwischen sprunghaften Änderungen und langsamen, graduellen Übergängen auszuleuchten und die Prinzipien der Änderungen und Erfindungen der Natur zu verstehen. Dabei gehen sie auch der Frage nach, welchen Einfluss das Auftreten neuer Gene auf die frühe Entwicklung von Organismen hat.

description: Das Ziel ist unstrittig: Es muss ein Umdenken hin zu mehr Nachhaltigkeit in Wirtschaft, Gesellschaft und Politik geben – nur so lassen sich Umwelt und Klima schützen und der soziale Zusammenhalt erhalten. Wie dieses Ziel aber zu erreichen ist, ist noch weitgehend offen. Wo und wann beginnt ein solcher Transformationsprozess? Wer unterstützt ihn und wer verzögert ihn? Und wo und wann endet Transformation, was kommt nach dem (erfolgreichen) Abschluss eines solchen Prozesses? Ein interdisziplinärer Blick, wie ihn die Forschung am Heidelberg Center for the Environment hat, kann dabei helfen, den Wert dieser Fragen zu erkennen und gleichzeitig Wege zu deren Beantwortung zu eröffnen.

description: We consider conservation laws on moving hypersurfaces. In this work the velocity of the surface is prescribed. But one may think of the velocity to be given by PDEs in the bulk phase. We prove existence and uniqueness for a scalar conservation law on the moving surface. This is done via a parabolic regularization of the hyperbolic PDE. We then prove suitable estimates for the solution of the regularized PDE, that are independent of the regularization parameter. We introduce the concept of an entropy solution for a scalar conservation law on a moving hypersurface. We also present some numerical experiments. As in the Euclidean case we expect discontinuous solutions, in particular shocks. It turns out that in addition to the "Euclidean shocks" geometrically induced shocks may appear.

description: Let $G$ be a graph and let $A(G)$ be the adjacency matrix of $G$. The signature $s(G)$ of $G$ is the difference between the positive inertia index and the negative inertia index of $A(G)$. Ma et al. [Positive and negative inertia index of a graph, Linear Algebra and its Applications 438(2013)331-341] conjectured that $-c_3(G)\leq s(G)\leq c_5(G),$ where $c_3(G)$ and $c_5(G)$ respectively denote the number of cycles in $G$ which have length $4k+3$ and $4k+5$ for some integers $k \ge 0$, and proved the conjecture holds for trees, unicyclic or bicyclic graphs. It is known that $s(G)=0$ if $G$ is bipartite, and the signature is closely related to the odd cycles or nonbipartiteness of a graph from the existed results. In this paper we show that the conjecture holds for the line graph and power trees.

Approximated Lax Pairs for the Reduced Order Integration of Nonlinear Evolution Equations
Creators: name: Gerbeau, Jean-Frédéric
name: Lombardi, Damiano
Publisher: name: arXiv
Year: 2014
Subjects: subject: Numerical Analysis (math.NA)

description: A reduced-order model algorithm, called ALP, is proposed to solve nonlinear evolution partial differential equations. It is based on approximations of generalized Lax pairs. Contrary to other reduced-order methods, like Proper Orthogonal Decomposition, the basis on which the solution is searched for evolves in time according to a dynamics specific to the problem. It is therefore well-suited to solving problems with progressive front or wave propagation. Another difference with other reduced-order methods is that it is not based on an off-line / on-line strategy. Numerical examples are shown for the linear advection, KdV and FKPP equations, in one and two dimensions.

Self-Consistent Ion Cyclotron Anisotropy-Beta Relation for Solar Wind Protons

description: We derive a set of self-consistent marginally stable states for a system of ion-cyclotron waves propagating parallel to the large-scale magnetic field through a homogeneous proton-electron plasma. The proton distributions and the wave dispersions are related through the condition that no further ion-cyclotron resonant particle scattering or wave growth/damping may take place. The thermal anisotropy of the protons in these states therefore defines the threshold value for triggering the proton-cyclotron anisotropy instability. A number of recent papers have noted that the anisotropy of solar wind protons at 1 AU does not seem to be limited by the proton-cyclotron anisotropy threshold, even at low plasma beta. However, this puzzle seems to be due solely to the estimation of this anisotropy threshold under the assumption that the protons have a bi-Maxwellian distribution. We note that bi-Maxwellian distributions are never marginally stable to the resonant cyclotron interaction, so these estimates do not represent physically valid thresholds. The threshold anisotropies obtained from our marginally stable states are much larger, as a function of proton parallel beta, than the bi-Maxwellian estimates, and we show that the measured data remains below these more rigorous thresholds. Thus, the results of this paper resolve the apparent contradiction presented by the solar wind anisotropy observations at 1 AU: The bi-Maxwellian anisotropies are not rigorous thresholds, and so do not limit the proton distributions in the solar wind.
