description: We present two possible approaches to calculate the momentum distribution n(p) and the Compton profile within the framework of the ab initio GW approximation on the self-energy. The approaches are based on integration of the Green's function along either the real or the imaginary axes. Examples will be presented on the jellium model and on real bulk sodium. Advantages and drawbacks of both methods are discussed in comparison with accurate quantum Monte Carlo (QMC) calculations and x-ray Compton scattering experiments. We illustrate the effect of many-body correlations and disentangle them from band-structure and anisotropy effects by a comparison with density functional theory in the local density approximation. Our results suggest the use of G0W0 momentum distributions as reference for future experiments and theory developments.

description: The ultimate accuracy as regards controlling a qubit with a coherent field is studied in terms of degradation of the fidelity by employing a fully quantum mechanical treatment. While the fidelity error accompanied by pi/2 pulse control is shown to be inversely proportional to the average photon number in a way similar to that revealed by the Gea-Banacloche's results. Our results show that the error depends strongly on the initial state of the qubit. When the initial state of the qubit is in the ground state, the error is about 20 times smaller than that of the control started from the exited state, no matter how large N is. This dependency is explained in the context of an exact quantum mechanical description of the pulse area theorem. By using the result, the error accumulation tendency of successive pulse controls is found to be both non-linear and initial state-dependent.

Local topological order inhibits thermal stability in 2D

description: We study the robustness of quantum information stored in the degenerate ground space of a local, frustration-free Hamiltonian with commuting terms on a 2D spin lattice. On one hand, a macroscopic energy barrier separating the distinct ground states under local transformations would protect the information from thermal fluctuations. On the other hand, local topological order would shield the ground space from static perturbations. Here we demonstrate that local topological order implies a constant energy barrier, thus inhibiting thermal stability.

Stress-induced patterns in ion-irradiated Silicon: a model based on anisotropic plastic flow

Subjects: subject: Mathematical Physics (math-ph)

description: We present a model for the effect of stress on thin amorphous films that develop atop ion-irradiated silicon, based on the mechanism of ion-induced anisotropic plastic flow. Using only parameters directly measured or known to high accuracy, the model exhibits remarkably good agreement with the wavelengths of experimentally-observed patterns, and agrees qualitatively with limited data on ripple propagation speed. The predictions of the model are discussed in the context of other mechanisms recently theorized to explain the wavelengths, including extensive comparison with an alternate model of stress.

description: We study by computer simulation a recently introduced generalised model of self-interacting self-avoiding trails on the square lattice that distinguishes two topologically different types of self-interaction: namely crossings where the trail passes across itself and collisions where the lattice path visits the same site without crossing. This model generalises the canonical interacting self-avoiding trail model of polymer collapse which has a strongly divergent specific heat at its transition point. We confirm the recent prediction that the asymmetry does not affect the universality class for a range of asymmetry. Certainly, where the weighting of collisions outweighs that of crossings this is well supported numerically. When crossings are weighted heavily relative to collisions the collapse transition reverts to the canonical theta-point-like behaviour found in interacting self-avoiding walks.

description: We briefly review the correspondence principle proposed in our previous paper, which claims that if we regard a matrix element defined in terms of the future state at time $T_B$ and the past state at time $T_A$ as an expectation value in the complex action theory whose path runs over not only past but also future, the expectation value at the present time $t$ of a future-included theory for large $T_B-t$ and large $t-T_A$ corresponds to that of a future-not-included theory with a proper inner product for large $t-T_A$. This correspondence principle suggests that the future-included theory is not excluded phenomenologically.

Close Galaxy Pairs at z = 3: A Challenge to UV Luminosity Abundance Matching

description: We use a sample of z~3 Lyman Break Galaxies (LBGs) to examine close pair clustering statistics in comparison to LCDM-based models of structure formation. Samples are selected by matching the LBG number density and by matching the observed LBG 3-D correlation function of LBGs over the two-halo term region. We show that UV-luminosity abundance matching cannot reproduce the observed data, but if subhalos are chosen to reproduce the observed clustering of LBGs we are able to reproduce the observed LBG pair fraction, (Nc), defined as the average number of companions per galaxy. This model suggests an over abundance of LBGs by a factor of ~5 over those observed, suggesting that only 1 in 5 halos above a fixed mass hosts a galaxy with LBG-like UV luminosity detectable via LBG selection techniques. We find a total observable close pair fraction of 23 \pm 0.6% (17.7 \pm 0.5%) using a prototypical cylinder radius in our overdense fiducial model and 8.3 \pm 0.5% (5.6 \pm 0.2%) in an abundance matched model (impurity corrected). For the matched spectroscopic slit analysis, we find Ncs = 5.1\pm0.2% (1.68\pm0.02%), the average number of companions observed serendipitously in our for fiducial slits (abundance matched), whereas the observed fraction of serendipitous spectroscopic close pairs is 4.7\pm1.5 per cent using the full LBG sample and 7.1\pm2.3% for a subsample with higher signal-to-noise ratio. We show that the standard method of halo assignment fails to reproduce the break in the LBG close pair behavior at small scale. To reconcile these discrepancies we suggest that a plausible fraction of LBGs in close pairs with lower mass than our sample experience interaction-induced enhanced star formation that boosts their luminosity sufficiently to be detected in observational sample but are not included in the abundance matched simulation sample.

This measure enables to compare, e.g., deterministic devices which prepare entangled states with low amount of entanglement with probabilistic devices which generate highly entangled states but which fail sometimes. We provide examples demonstrating advantages of this new measure over the so far employed entangling power.

description: We present an experimental platform for measuring hydrogen Balmer emission and absorption line profiles for plasmas with white dwarf (WD) photospheric conditions (T_e ~ 1 eV, n_e ~ 10^17 cm^-3). These profiles will be used to benchmark WD atmosphere models, which, used with the spectroscopic method, are responsible for determining fundamental parameters (e.g., effective temperature, mass) for tens of thousands of WDs. Our experiment, performed at the Z Pulsed Power Facility at Sandia National Laboratories, uses the large amount of x-rays generated from a z-pinch dynamic hohlraum to drive plasma formation in a gas cell. The platform is unique compared to past hydrogen line profile experiments in that the plasma is radiation-driven. This decouples the heating source from the plasma to be studied in the sense that the radiation temperature causing the photoionization is independent of the initial conditions of the gas. For the first time we measure hydrogen Balmer lines in absorption at these conditions in the laboratory for the purpose of benchmarking Stark-broadened line shapes. The platform can be used to study other plasma species and to explore non-LTE, time-dependent collisional-radiative atomic kinetics.

The Second Bible of Charles the Bald: Patronage and Intellectual Community at St. Amand

description: Abstract: among the manuscripts produced for Charles the Bald, King of West Francia (843-77) and Holy Roman Emperor (875-77), the so-called Second Bible (Paris, BnF, MS Lat. 2) holds a special place. Illuminated in the scriptorium of the abbey of St. Amand between 870 and 873, the Bible—unlike all the other manuscripts presented to the king during this period—contains no human figures or royal portraits. It exhibits instead large initials patterned with geometric and zoomorphic designs. In addition, the volume opens with a long poem dedicated to Charles the Bald and written by Hucbald (ca. 840–930), master of the monastery school at St. Amand. Although Carolingian scholarship has investigated the manuscript’s ornament, the relationship between Hucbald’s poetry and the book’s decorative program has never been systematically examined. By analyzing both the use of script as image and Hucbald’s poem, this article sheds light on the Bible’s intended purpose and message. Moreover, the article contributes to a more precise understanding of Charles the Bald’s role as patron of St. Amand. It argues that the Bible not only represents the increasingly close relationship between the abbey and the crown, but also functions as a special vehicle that carries the abbey’s pleas straight to the king’s heart.

description: In-medium modification of the eta' mass is discussed in the context of partial restoration of chiral symmetry in nuclear medium. We emphasize that the U_A(1) anomaly effects causes the eta'-eta mass difference necessarily through the chiral symmetry breaking. As a consequence, the eta' mass is expected to be reduced by order of 100 MeV in nuclear matter where about 30% reduction of chiral symmetry takes place. The strong attraction relating to the eta' mass generation eventually implies that there should be also a strong attractive interaction in the scalar channel of the eta'-N two-body system. We find that the attraction can be strong enough to form a bound state.

An Exploration of the Time Element in the Linguistic Landscape and Reconstructing Culture: The Case of Langtou Village in China

description: The tourism industry has penetrated traditional Chinese villages, where the linguistic landscape reflects a dialogue between historical heritage and contemporary culture, thereby redefining the transformation of China's rural cultural ecology. The researchers gathered 475 images of the linguistic landscape through fieldwork in Langtou Village and conducted a qualitative investigation within the context of Chinese cultural history and village history. Based on Huebner's (2008) speaking model, researchers investigated the potential influence of time elements in the linguistic landscape on the cultural reconstruction of the village. We conclude that the linguistic landscape of Langtou Village encompasses seven types of time elements, which essentially observe content time, creation time, and feature time. The commonalities or differences among these elements give rise to time trajectories that influence the cultural reconstruction of Langtou Village. One is the cultural reconstruction of cherishing memory, which perpetuates historical information. Another is the cultural reconstruction of combining moments, which amalgamates contemporary culture and poses the risk of inauthenticity in historical villages. The study suggests that the distribution of time elements in linguistic landscapes exhibits hierarchy in real settings, which is related to the spatial regularity induced by the village's historical information. We believe that adopting a time-element-oriented perspective can deliver new recommendations for the linguistic landscape planning of traditional Chinese villages. This research inspires readers to comprehend the essence of the relationship between rural linguistic landscapes and cultural ecology, specifically: what is the smallest unit of interaction between historical and contemporary culture in the context of reconstruction?

Cosmic bulk flows on 50 {h}^{-1}Mpc scales: A Bayesian hyper-parameter method and multishells likelihood analysis

description: It has been argued recently that the galaxy peculiar velocity field provides evidence of excessive power on scales of $50\hmpc$, which seems to be inconsistent with the standard $Λ$CDM cosmological model. We discuss several assumptions and conventions used in studies of the large-scale bulk flow to check whether this claim is robust under a variety of conditions. Rather than using a composite catalogue we select samples from the SN, ENEAR, SFI++ and A1SN catalogues, and correct for Malmquist bias in each according to the IRAS PSCz density field. We also use slightly different assumptions about the small-scale velocity dispersion and the parameterisation of the matter power spectrum when calculating the variance of the bulk flow. By combining the likelihood of individual catalogues using a Bayesian hyper-parameter method, we find that the joint likelihood of the amplitude parameter gives $σ_8=0.65^{+0.47}_{-0.35}(\pm 1 σ)$, which is entirely consistent with the $Λ$CDM model. In addition, the bulk flow magnitude ($v \sim 310 \kms$) and direction, $(l,b)\sim (280^{\circ} \pm 8^{\circ}, 5.1^{\circ} \pm 6^{\circ})$, found by each of the catalogues are all consistent with each other, and with the bulk flow results from most previous studies. Furthermore, the bulk flow velocities in different shells of the surveys constrain $σ_{8}$--$Ω_{\rm{m}}$ to be ($1.01^{+0.26}_{-0.20},0.31^{+0.28}_{-0.14}$, SFI++) and ($1.04^{+0.32}_{-0.24},0.28^{+0.30}_{-0.14}$, ENEAR), which is consistent with {\it WMAP} 7-year best-fit values. We finally discuss the differences between our conclusions and those of the studies claiming the largest bulk flows.

description: There is convincing numerical evidence that fractional quantum Hall (FQH)-like ground states arise in fractionally filled Chern bands (FCB). Here we show that the Hamiltonian theory of Composite Fermions (CF) can be as useful in describing the FCB as it was in describing the FQHE in the continuum. We are able to introduce CFs into the FCB problem even though there is no external magnetic field by following a two-stage process. First we construct an algebraically exact mapping which expresses the electron density projected to the Chern band, $ρ_{\tiny FCB}$, as a sum of Girvin-MacDonald-Platzman density operators, $ρ_{\tiny GMP}$, that obey the Magnetic Translation Algebra. Next, following our Hamiltonian treatment of the FQH problem, we rewrite the GMP operators in terms of CF variables which reproduce the same algebra. This naturally produces a unique Hartree-Fock ground state for the CFs, which can be used as a springboard for computing gaps, response functions, temperature-dependent phenomena, and the influence of disorder. We give two concrete examples, one of which has no analog in the continuum FQHE with $ν= {1 \over 5}$ and $σ_{xy}={2\over 5}$. Our approach can be easily extended to fractionally filled, strongly interacting two-dimensional time-reversal-invariant topological insulators.

description: We study the self energy of a charged particle located in a static D-dimensional gravitational field. We show that the energy functional for this problem is invariant under an infinite dimensional (gauge) group of transformations parameterized by one scalar function of (D-1)-variables. We demonstrate that the problem of the calculation of the self energy for a pointlike charge is equivalent to the calculation of the fluctuations $$ for an effective (D-1)-dimensional Euclidean quantum field theory. Using point-splitting regularization we obtain an expression for the self energy and show, that it possesses anomalies. Explicit calculation of the self energy and its anomaly is done for the higher dimensional Majumdar-Papapetrou spacetimes.

Material examined. New Caledonia: CONCALIS cruise, stn. DW 2997, New Caledonia, 18°01.98’S 163°01.51’E, 430–438 m, 6 May 2008: 1 male (27.9 x 21.7 mm) (ZRC 2008.0978). Remarks. Homola mieensis is a relatively large-size species but rarely recorded. Described from Sagami Bay in Japan (Sakai 1979), it has been found in Taiwan (Ng et al. 2001) and New Caledonia (Guinot & Richer de Forges 1981, 1995). The species has a very distinctive colour pattern (Ng et al. 2001: Fig. 1A). Compared to congeners, the subhepatic spine is proportionately longer and stronger than the anterolateral one, pointing anteriorly and diverging only slightly. There are no fissures at the extremity of the rostrum on the male specimen on hand; it appears to be single. Very few specimens of H. mieensis are known because its preferred habitat appears to be steep rocky slopes. The material from Loyalty Islands off New Caledonia (Guinot & Richer de Forges 1981, 1995) was caught by traps and the present specimen from the north of New Caledonia by dredging. The dredge is generally used when the bottom is too rough or too steep for trawling.

description: We investigate the possibility of multi-band superconductivity in SrTiO$_{3}$ films and interfaces using a two-dimensional two-band model. In the undoped compound, one of the bands is occupied whereas the other is empty. As the chemical potential shifts due to doping by negative charge carriers or application of an electric field, the second band becomes occupied, giving rise to a strong enhancement of the transition temperature and a sharp feature in the gap functions, which is manifested in the local density of states spectrum. By comparing our results with tunneling experiments in Nb-doped SrTiO$_{3}$, we find that intra-band pairing dominates over inter-band pairing, unlike other known multi-band superconductors. Given the similarities with the value of the transition temperature and with the band structure of LaAlO$_{3}$/SrTiO$_{3}$ heterostructures, we speculate that the superconductivity observed in SrTiO$_{3}$ interfaces may be similar in nature to that of bulk SrTiO$_{3}$, involving multiple bands with distinct electronic occupations.

description: We consider hadronic transitions from the $h_b(2P)$ bottomonium resonance to lower states of bottomonium with emission of either $ω$ meson, or two pions, or $η$ meson. For the former two transitions the branching ratios are related to similar transitions from $χ_{b1}(2P)$ and the recently measured by Belle fractions of the radiative decays of $h_b(2P)$. We argue that the fraction of the $h_b(2P)$ total decay rate remaining for the annihilation rate is on the verge of contradiction with the `parton' picture of bottomonium annihilation resulting in similarity between the decays of $h_b(1,2P)$ and $χ_{b1}(1,2P)$. The contradiction gets even stronger, if the transition $h_b(2P) \to Υ(1S) \, η$ has branching fraction of a few percent or more. We argue that, although quite uncertain, the latter fraction may indeed be that significant.

title: The effect of different flicker contrasts on the Dynamic Vessel Analysis

Subjects: subject: 610

description: Purpose : Retinal arterioles and venules dilate when stimulated with flickering light. This phenomenon is described as functional hyperemia and closely associated with neurovascular coupling. The flicker causes a short period of heightened cellular metabolism which increases the need for blood. As a result the retinal vessels dilate and the blood flow increases. The dynamic vessel analysis (DVA) is a non-invasive method to measure these processes. However, the influence of different flicker contrasts on the vaso-dilation is still unclear. This work aims to clarify whether the DVA is affected by different flicker contrasts. Methods : The relative vaso-dilation values of 15 volunteers (12m, 3f, 23.2±1.6 years, one eye) were measured using a modified Retinal Vessel Analyzer (Imedos Systems GmbH; standard protocol: duration of 350 seconds). Exclusion criteria were visual acuity less than 0.5, astigmatism >2.0 D, myopia > 5.0 D and ocular and systemic diseases. We investigated two primary vessel segments (superior temporal artery (STa) and vein (STv)) located between 0.5 and 2.0 disc diameters from the optic disc. For each volunteer the DVA was performed six times (rest period: 10min) in a randomized order using different flicker contrasts (c: 0.98, 0.92, 0.85, 0.72, 0.50, 0.20; based on Michelson). To modulate the contrast we used a spatial light modulator (Sony Cooperation; controlled by a VGA interface) placed in the optically conjugated fundus plane. Contrast values below 0.98 were achieved by controlling with gray values greater than zero (graphics card space 8bit, R=G=B>0). For statistical analysis the t-test and the Wilcoxon test for paired samples were used and Bonferroni corrected. Results : In all volunteers a reduction of flicker contrasts showed a reduction of the vaso-dilation values for both veins and arteries. Based on the almost ideal contrast (0.98), the following p-values for the differences were obtained: c=0.98-0.92/0.98-0.85/0.98-0.72/0.98-0.50/0.98-0.20 STa: p=0.999/0.999/0.032/0/0; STv: p=0.807/0.002/0.001/0/0. Conclusions : The presented work revealed, that a reduction in flicker contrast leads to less vaso-dilation values. Already at about 70% (for arteries) or 85% (for veins) contrast the vaso-dilation is significantly reduced compared to ideal contrasts (≥98%). In studies with patients who suffer e.q. from clouded lenses this should be considered.

description: Purpose : Ocular electrical stimulation exhibit potential for the treatment of neurodegenerative ocular diseases. However, the underlying mechanism in the retinal cells remains subject of research. Studies applying transcranial electrical stimulation show that direct current stimulation (DCS) over the visual cortex manipulates the amplitudes of visual evoked potentials. An anodal DCS leads to increased amplitudes while a cathodal DCS decreased these amplitudes. We hypothesize that the retinal cells show similar reactions. Methods : We stimulated 15 volunteers (8m, 7f, 23.5 ± 1.6 years, one eye) with a cathodal DCS of 500 µA (DC-stimulator MC, neuroConn GmbH, Ilmenau) for 10 minutes. For DCS we used six cup electrodes (diameter: 0.95 cm) placed around one eye . Before, during and after DCS we measured the electrophysiological answer of the retinal ganglion cells using a pattern-reversal stimulus (stimulus field: 1° individual checks, 16° total; reversals per second: 4; Michelson contrast: 99%; mean luminance: 186 cd/m^2). For recording, we used Ag/AgCl ring electrodes located at the lower eyelid and the earlobe. For statistical analysis the Friedman test for paired samples and a confidence interval analysis was performed. Results : The characteristic amplitudes of the the electrophysiological answer (P50 and N95 component) as well as its peak-to-peak difference (PPD) were decreased during the stimulation. The visible trend was statistically not significant (Friedman test P50/N95/PPD: p = 0.527/0.574/0.297). Under consideration of specific volunteers (showed expected reduction of the N95 component, n = 9) we found a significant change of the N95 component for the difference between before and during DCS (confidence interval analysis, lower limit: -2.45 µV; upper limit: -0.38 µV; after Bonferroni correction α = 0.0143). Conclusions : The performed study indicates a trend that a cathodal DCS decreasing electrophysiological activity in the retina.

description: We present a next-to-leading order (NLO) computation of the full set of polarized and unpolarized electroweak semi-inclusive DIS (SIDIS) structure functions, whose knowledge is crucial for a precise extraction of polarized parton distributions. We focus on the phenomenology of the polarized structure functions for the kinematical conditions that could be reached in an Electron-Ion-Collider. We show that the NLO corrections are sizeable, particularly in the small-$x$ range. We test the sensitivity of these structure functions on certain quark distributions and compare it to the situation of inclusive DIS and electromagnetic SIDIS.

description: Over the past two decades, processes of digitalization and mediatization have shaped the communication landscape and have had a strong impact on various facets of communication. The digitalization of communication results in completely new forms of digital traces that make communication processes observable in new and unprecedented ways. Although many scholars in the social sciences acknowledge the chances and requirements of the digital revolution in communication, they are also facing fundamental challenges in implementing successful research programs, strategies, and designs that are based on computational methods and “big data.” This Special Section aims at bringing together seminal perspectives on challenges and chances of computational communication science (CCS). In this introduction, we highlight the impulses provided by the research presented in the Special Section, discuss the most pressing challenges in the context of CCS, and sketch a potential roadmap for future research in this field.
