description: Composites play an increasingly important role in contemporary aircraft. Delaminations are of significant concern for composites and have been observed in aircraft in operational use. Compliance with criteria defined in JSSG2006 requires growth of delaminations to be either avoided, or to be predictable, slow and stable. This thesis examines historical approaches to delamination modelling, and proposes methods for accounting for the extensive data scatter seen in carbon/epoxy composites to provide indicative thresholds for airframe design. The growth of delaminations from naturally occurring material defects is also studied, and a novel approach of modelling delaminations and non-linearity in composites is proposed.

0037 Phonemes, Graphemes, Dabs of Paint: Roman Jakobson, the Russian avant-garde and the search for the shared basic elements of painting and poetry
Creators: name: Hofstede, Bregje
Publisher: name: RIHA Journal
Year: 2019

description: The subject of this paper is the supposed affinity between painting and poetry as theorised by the linguist Roman Jakobson who played a crucial role for the Russian avant-garde and its close association of painting and poetry. The paper focuses on Jakobson's relation to the two 1913 manifestos "The Word as Such" and "The Letter as Such", written by the poets Chlebnikov and Kruchenyck, and on Jakobson's own (lost) reply. It calls into question the accuracy of Jakobson's claim of having influcenced the poets' manifestos, and describes what Jakobson considered to be the shared 'core elements' of the visual and literary arts. According to him, they share a visuality, not on the level of the written sign or grapheme, but on a deeper level, visible only to the mind's eye.

description: We measure the correlation of clustering to color and stellar mass in spectroscopic galaxies at 0.6 < z < 0.65 using data from the Baryon Oscillation Spectroscopic Survey (BOSS) component of the Sloan Digital Sky Survey (SDSS-III). The clustering strength of each spectroscopic galaxy is measured as the number of photometric galaxies found within a specified radius annulus around it. We cross-correlate 66,657 (after redshift selection) spectroscopic galaxies with 6,625,645 imaging galaxies to measure clustering coefficients ωred and ωblue for red and blue galaxies (defined as g — i > or < 2.35). We find the ratio of these coefficients, wred/wblue, to be 1.921 \(\pm\) 0.11 in our smallest annulus of 75-125 kpc. At our largest radii (2-4 Mpc), we find wred/wblue to be 1.243 span class="math-tex">\(\pm\)/span> 0.05. Red galaxies therefore have denser environments that their blue counterparts at span class="math-tex">\(z \approx\)/span> 0.625, and this effect heightens with decreasing radius. Irrespective of color, we find that omega; does not obey a simple power law relation with radius, showing a dip around 1 Mpc attributable to the transition from one- to two-halo regimes in HOD models. Holding mass fixed, we find a clear differentiation between clustering in red and blue galaxies, showing that clustering is not solely determined by stellar mass. Holding color fixed, we find that clustering increases with mass, and that this relationship is especially strong in red galaxies at small scales (a factor of 2 effect)./p>

Comparing Positions Of Molecular Clouds And Masers In The Milky Way

description: In my project I compare Thomas Rice's dendrogram catalog of molecular gas in the Milky Way with data from the Bar and Spiral Structure Legacy (BeSSeL) Survey. Rice, a member of Harvard University's class of 2012, created this catalog as his senior thesis. He used the dendrogram technique to segment CO in the Milky Way into individual clouds. The dendrogram creates a tree diagram, in which the leaves are peaks in CO intensity. The BeSSeL Survey found parallaxes for methanol maser sources using the Very Large Baseline Array (VLBA). Because these sources are associated with regions of massive star formation in the spiral arms of the galaxy, their locations in the Milky Way yield information about the star forming regions in the spiral arms. They should correspond to peaks in CO, which were identified as clouds in the dendrogram. By matching points between the catalogs based on their locations and by plotting BeSSeL points directly on the dendrogram, I show correspondence between the two data sets. A parallax distance could be assigned to those clouds that have an associated maser, and these parallax distances could change what we know about the molecular clouds. I also show that the dendrogram technique is a viable automated technique for segmenting CO into clouds and assigning masers to those clouds.

description: The Fermi surfaces (FS's) and band dispersions of EuRh2As2 have been investigated using angle-resolved photoemission spectroscopy. The results in the high-temperature paramagnetic state are in good agreement with the full potential linearized augmented plane wave calculations, especially in the context of the shape of the two-dimensional FS's and band dispersion around the Gamma (0,0) and X (pi,pi) points. Interesting changes in band folding are predicted by the theoretical calculations below the magnetic transition temperature Tn=47K. However, by comparing the FS's measured at 60K and 40K, we did not observe any signature of this transition at the Fermi energy indicating a very weak coupling of the electrons to the ordered magnetic moments or strong fluctuations. Furthermore, the FS does not change across the temperature (~ 25K) where changes are observed in the Hall coefficient. Notably, the Fermi surface deviates drastically from the usual FS of the superconducting iron-based AFe2As2 parent compounds, including the absence of nesting between the Gamma and X FS pockets.

description: From climate change effects to biodiversity loss and local population reduction in the internal areas even the mountain landscapes experimented dramatic changes in the last few decades. This contribution is the result of a self-financed initiative, supported by the warm hospitality of some locals and is based on a field-on research activity conducted through the involvement of some locals in a participative approach, taking into account also some valuable evidences deriving from local ecological knowledge.Similarly, to what happened in the ocean and coastal environment even the mountain landscape changed. Prolonged drought periods beside the dramatic reduction of pluvial income determined a significant variation in the overall ecosystem functioning.Despite the not so encouraging trends affecting some representative of terrestrial and marine ecosystems the study of biodiversity can be one of the most challenging field of investigation, able to give curious insight even in the less renowned sites and unbeaten localities.

description: The definition of 'classical state', and how it was used in earlier work to prove a decomposition theorem internally in the language of State Property Systems, presupposes as an additional datum an orthocomplementation on the property lattice of a physical system. In this paper we argue on the basis of the epsilon-model on the Poincare sphere that a notion of 'topologicity' for states can be seen as an alternative (operationally foundable) classicality notion in the absence of an orthocomplementation, and compare it to the known and operationally founded concept of classicality.

description: We report on optical spectroscopy of 165 Flat Spectrum Radio Quasars (FSRQs) in the Fermi 1LAC sample, which have helped allow a nearly complete study of this population. Fermi FSRQ show significant evidence for non-thermal emission even in the optical; the degree depends on the gamma-ray hardness. They also have smaller virial estimates of hole mass than the optical quasar sample. This appears to be largely due to a preferred (axial) view of the gamma-ray FSRQ and non-isotropic (H/R ~ 0.4) distribution of broad-line velocities. Even after correction for this bias, the Fermi FSRQ show higher mean Eddington ratios than the optical population. A comparison of optical spectral properties with Owens Valley Radio Observatory radio flare activity shows no strong correlation.

description: We explore the magnetoresistance (MC) effect in an organic semiconductor device based on the magnetic field related bipolaron formation. By establishing a group of dynamic equations, we present the transition among spin-parallel, spin-antiparallel polaron pairs and bipolarons. The transition rates are adjusted by the external magnetic field as well as the hyperfine interaction of the hydrogen nuclei. The hyperfine interaction is addressed and treated in the frame work of quantum mechanics. By supposing the different mobility of polarons from that of bipolarons, we obtain the MC in an organic semiconductor device. The theoretical calculation is well consistent to the experimental data. It is predicated that a maximum MC appears at a suitable branching ratio of bipolarons. Our investigation reveals the important role of hyperfine interaction in organic magnetic effect.

description: the storage infrastructure is the foundation on which information relies and therefore must support a company's business objectives and business model. In this environment, simply deploying more and faster storage devices is not enough; a new kind of infrastructure is needed, one that provides more enhanced network availability, data accessibility, and system manageability than is provided by today's infrastructure. The SAN meets this challenge. The SAN liberates the storage device, so it is not on a particular server bus, and attaches it directly to the network. In other words, storage is externalized and functionally distributed across the organization. The SAN also enables the centralizing of storage devices and the clustering of servers, which makes for easier and less expensive administration. So the idea is to create an intelligent SAN infrastructure that stretches to meet increased demands, allows highly available and heterogeneous access to expanding information.

description: This research compares the outcomes of two computer-assisted second language (L2) idiom learning conditions: deliberate and contextual. Low-intermediate proficiency Japanese learners of English studied 36 idioms online by either using flashcards or reading them in sentences with contextual clues to their meanings over three learning sessions. Posttest results of these two learning conditions were compared with each other and with a baseline condition in which no learning occurred. In an idiom translation posttest, L2 participants showed superior declarative knowledge of the idioms learned in the flashcard condition. Nondeclarative knowledge gains were measured on a self-paced reading (SPR) task validated in a pilot study with 60 native (L1) readers. Although the idioms primed semantic probes during reading for the L1 participants, this was not the case for the L2 learners. Nevertheless, the two learning conditions had some positive effects on the semantic probes compared to the baseline. The finding that participants had fluent access to the idioms’ figurative meanings while reading the semantic probes is particularly important for the flashcard condition because it suggests that this learning approach results in knowledge relevant in real-time language use.

description: The purpose of the present study was to investigate whether the markers of oxidative stress could be altered in workers exposed to asbestos. A comparative cross-sectional research was conducted in a group of 50 subjects exposed to asbestos and another group of 50 with the same age and sex unexposed to asbestos. Malondialdehyde (MDA), total thiol molecule (TTM), total antioxidant capacity (TAC), and DNA damage, were measured in the blood samples of workers and controls. Compared to the control group, the workers showed higher blood levels of DNA damage (P=0.0001) and MDA (P=0.0001). The workers showed lower TTM (P=0.02) as compared with the control group. There was no considerable difference on the level of TAC (P=0.1) between the groups. The workers indicated clinical symptoms such as breathlessness, phlegm, coughing and wheezing. There was a positive correlation between levels of 8-OHdG and MDA of asbestos workers and the smoking status suggesting the negative role of smoking.

Some Systematics of Galactic Globular Clusters

subject: FOS: Physical sciences

description: The global properties of all known Galactic globular clusters are examined. The relationship between the luminosities and the metallicities of Galactic globular clusters is found to be complex. Among luminous clusters there is a correlation in the sense that the oldest clusters are slightly more metal deficient than are younger clusters. However, no such clear-cut relationship is found among the faintest globular clusters. The central concentration index C of globular clusters is seen to be independent of metallicity. The dependence of the half-light radii of globular clusters on their Galactocentric distances can be approximated by the relation $R_h α R^{2/3}_{gc}$. Clusters with collapsed cores are mostly situated close to the Galactic nucleus. For $R_{gc} < 10$ kpc the luminosities and the radii of clusters appear to be uncorrelated. The Galaxy differs from the LMC and the SMC in that it appears to lack highly flattened luminous clusters. Galactic globular clusters with ages $\geq$ 13.0 Gyr are all of Oosterhoff type II, whereas almost all of those with ages $

This phenomenon can be called inverse transverse magneto-optical Kerr effect. The femtosecond laser pulse of peak intensity of 500 W/μm2 generates in nickel an effective magnetic field of about 100 Oe. The value of the effective magnetic field can be increased by more than an order of magnitude at the surface plasmon polariton resonance excited in smooth metal dielectric structures or in plasmonic crystals.

description: Chaperone-Usher Pathway (CUP) pili are major adhesins in Gram-negative bacteria, mediating bacterial adherence to biotic and abiotic surfaces. While classical CUP pili have been extensively characterized, little is known about so-called archaic CUP pili, which are phylogenetically widespread and promote biofilm formation by several human pathogens. In this study, we present the electron cryomicroscopy structure of the archaic CupE pilus from the opportunistic human pathogen Pseudomonas aeruginosa. We show that CupE1 subunits within the pilus are arranged in a zigzag architecture, containing an N-terminal donor β-strand extending from each subunit into the next, where it is anchored by hydrophobic interactions, with comparatively weaker interactions at the rest of the inter-subunit interface. Imaging CupE pili on the surface of P. aeruginosa cells using electron cryotomography shows that CupE pili adopt variable curvatures in response to their environment, which might facilitate their role in promoting cellular attachment. Finally, bioinformatic analysis shows the widespread abundance of cupE genes in isolates of P. aeruginosa and the co-occurrence of cupE with other cup clusters, suggesting interdependence of cup pili in regulating bacterial adherence within biofilms. Taken together, our study provides insights into the architecture of archaic CUP pili, providing a structural basis for understanding their role in promoting cellular adhesion and biofilm formation in P. aeruginosa.

description: Secondary interventions after endovascular repair of abdominal aortic aneurysms are frequent because stent-graft (SG) related complications may occur (mainly endoleak and SG thrombosis). Complications have been related to insufficient SG flexibility, especially when devices are deployed in tortuous arteries. Little is known on the relationship between SG design and flexibility. Therefore, the aim of this study was to simulate numerically the bending of two manufactured SGs (Aorfix-Lombard Medical (A) and Zenith-Cook Medical Europe (Z)) using finite element analysis (FEA). Global SG behavior was studied by assessing stent spacing variation and cross-section deformation. Four criteria were defined to compare flexibility of SGs: maximal luminal reduction rate, torque required for bending, maximal membrane strains in graft and maximal Von Mises stress in stents. For angulation greater than 60\degree, values of these four criteria were lower with A-SG, compared to Z-SG. In conclusion, A-SG was more flexible than Z-SG according to FEA. A-SG may decrease the incidence of complications in the setting of tortuous aorto-iliac aneurysms. Our numerical model could be used to assess flexibility of further manufactured as well as newly designed SGs.

description: The classical method for measure the Earth-Sun distance is due to Aristarchus and it is based upon the measure of the angle Moon-Earth-Sun when the Moon is exactly in quadrature. Such an angle is only 9 arcminutes smaller than 90 degrees, and it is very difficult to evaluate, being necessary to look directly towards the Sun. The distance Earth-Moon and the Earth's diameter are necessary ingredients in order to derive the value of the astronomical unit. This method requires also the knowledge of the Moon's distance and the Earth's diameter, but it can permit a more precise measurement of the involved angles.

description: We present CARMA 1.3 mm continuum observations of the T Tauri star LkCa 15,which resolve the circumstellar dust continuum emission on angular scales between 0.2-3 arcsec, corresponding to 28-420 AU at the distance of the star. The observations resolve the inner gap in the dust emission and reveal an asymmetric dust distribution in the outer disk. (Abridge) We calculate that 90% of the dust emission arises from an azimuthally symmetric ring that contains about 5x10^{-4} M_sun of dust. A low surface-brightness tail that extends to the northwest out to a radius of about 300 AU contains the remaining 10% of the observed continuum emission. The ring is modeled with a rather flat surface density profile between 40 and 120 AU, while the inner cavity is consistent with either a sharp drop of the 1.3 mm dust optical depth at about 42 AU or a smooth inward decrease between 3 and 85 AU. (Abridge). Within 40 AU, the observations constrain the amount of dust between 10^{-6} and 7 Earth masses, where the minimum and maximum limits are set by the near-IR SED modeling and by the mm-wave observations of the dust emission respectively. In addition, we confirm the discrepancy in the outer disk radius inferred from the dust and gas, which corresponds to 150 AU and 900 AU respectively. We cannot reconcile this difference by adopting an exponentially tapered surface density profile as suggested for other systems, but we instead suggest that the gas surface density in the outer disk decreases less steeply than that predicted by model fits to the dust continuum emission. The lack of continuum emission at radii lager than 120 AU suggests a drop of at least a factor of 5 in the dust-to-gas ratio, or in the dust opacity. We show that a sharp dust opacity drop of this magnitude is consistent with a radial variation of the grain size distribution as predicted by existing grain growth models.

We correct for randomness and for finite size effects and we find significant prob- ability of joint drawups for certain pairs of CDS. We also find significant probability of trend rein- forcement, i.e. drawups in a given CDS followed by drawups in the same CDS. Finally, we take the matrix of probability of joint drawups as an estimate of the network of financial dependencies among institutions. We then carry out a network analysis that provides insights into the role of systemically important financial institutions.

description: We identify the ring of odd symmetric functions introduced by Ellis and Khovanov as the space of skew polynomials fixed by a natural action of the Hecke algebra at q=-1. This allows us to define graded modules over the Hecke algebra at q=-1 that are `odd' analogs of the cohomology of type A Springer varieties. The graded module associated to the full flag variety corresponds to the quotient of the skew polynomial ring by the left ideal of nonconstant odd symmetric functions. The top degree component of the odd cohomology of Springer varieties is identified with the corresponding Specht module of the Hecke algebra at q=-1.

description: Predictions of the anisotropic magnetic susceptibility chi below the antiferromagnetic (AFM) ordering temperatures TN of local moment Heisenberg AFMs have been made previously using molecular field theory (MFT) but are very limited in their applicability. Here a MFT calculation of chi(T<=TN) is presented for a wide variety of collinear and noncollinear Heisenberg AFMs containing identical crystallographically equivalent spins without recourse to magnetic sublattices. The results are expressed in terms of directly measurable experimental parameters and are fitted with no adjustable parameters to experimental chi(T<=TN) data from the literature for several collinear and noncollinear AFMs. The influence of spin correlations and fluctuations beyond MFT is quantified by the deviation of the theory from the data. The origin of the universal chi(T<=TN) observed for triangular lattice AFMs exhibiting coplanar noncollinear 120 degree AFM ordering is clarified.

Subjects: re3data, repository, registry, research data, NFDI, open science, re3data COREF

description: For more than ten years, re3data, a global registry of research data repositories (RDR), has supported researchers, funding agencies, libraries, and data centers with finding, identifying and referencing RDR. As the world's largest directory of RDR, re3data currently describes over 3000 RDR on the basis of a comprehensive metadata schema. The service allows searching for RDR of any type and from all disciplines, and users can filter results based on a wide range of characteristics. The re3data RDR descriptions are available as open data accessible through an API and are utilized by numerous open science services. re3data is engaged in various initiatives and projects concerning data management and is mentioned in the policies of many scientific institutions, funding organizations, and publishers.

 As a central international registry for research data repositories, the re3data team is ready to explore how re3data can effectively contribute to the emerging NFDI network in Germany. A key goal of the presentation was to hear the views of NFDI consortium members on the topic of research data repositories and how we as re3data can further support their activities in the NFDI. You can find the recorded presentation on Youtube.

Proton-nucleus total reaction cross sections in the optical limit Glauber theory: Subtle dependence on the equation of state of nuclear matter

description: We calculate the proton-nucleus total reaction cross sections at different energies of incident protons within the optical limit approximation of the Glauber theory. The isospin effect has been taken into account. The nucleon distribution is obtained in the framework of macroscopic nuclear models in a way depending on the equation of state of uniform nuclear matter near the saturation density. We find that at an energy of order 40 MeV, the reaction cross section calculated for neutron- rich isotopes significantly increases as the parameter L characterizing the density dependence of the symmetry energy increases, while at energies of order 300 and 800 MeV, it is almost independent of L. This is a feature of the optical limit Glauber theory in which an exponential dependence of the reaction cross section on the neutron skin thickness remains when the total proton-neutron cross section is small enough.

description: Based on the largest homogeneously reduced set of Type Ia supernova luminosity data currently available -- the Union2 sample -- we reconstruct the expansion history of the Universe in a model-independent approach. Our method tests the geometry of the Universe directly without reverting to any assumptions made on its energy content. This allows us to constrain Dark Energy models and non-standard cosmologies in a straightforward way. The applicability of the presented method is not restricted to testing cosmological models. It can be a valuable tool for pointing out systematic errors hidden in the supernova data and planning future Type Ia supernova cosmology campaigns.

description: A special theme session and workshop on data-limited stock assessments was held at the 67th annual conference of the Gulf and Caribbean Fisheries Institute (GCFI) in Barbados, West Indies during November 3-7, 2014. Contributors to the GCFI special session provided presentations on a variety of topics relating to fishery-dependent data collection. The 1.5 day GCFI workshop provided an opportunity for scientists, managers, and stakeholders to identify and prioritize the optimal elements to incorporate in designing efficient data-dependent statistical collections. A pre-workshop questionnaire survey was employed to obtain information on the backgrounds of attendees and level of involvement in data collection systems. Presentations included an overview linking management to data collection, and case studies describing existing data collection systems in the region. Participants listened to presentations on best practices for biological data collections and novel approaches for engaging stakeholders in data collection. Participants also engaged in an interactive activity to design a data collection system for a specified level of resources. During the workshop, participants were involved in breakout group sessions addressing: 1) linkages between data and management needs, 2) stakeholder involvement and improving communication, 3) electronic monitoring, and 4) the use of management strategy evaluation (MSE) as a tool to simulate the effectiveness of management advice. Participants addressed key questions on what data collection practices are currently being used to minimize uncertainty in data-limited assessments. Finally, the workshop participants identified best practices relating to minimum data collection for improving data-limited stock assessments in the Caribbean region, taking into consideration financial resource availability.

description: We study the Maker-Breaker game on the hypergraph of chains of fixed size in a poset. In a product of chains, the maximum size of a chain that Maker can guarantee building is $k-\lfloor r/2\rfloor$, where $k$ is the maximum size of a chain in the product, and $r$ is the maximum size of a factor chain. We also study a variant in which Maker must follow the chain in order, called the {\it Walker-Blocker game}. In the poset consisting of the bottom $k$ levels of the product of $d$ arbitrarily long chains, Walker can guarantee a chain that hits all levels if $d\ge14$; this result uses a solution to Conway's Angel-Devil game. When d=2, the maximum that Walker can guarantee is only 2/3 of the levels, and 2/3 is asymptotically achievable in the product of two equal chains.

description: We study constraints on the models of bosonic super-weakly interacting particle (super-WIMP) dark matter (DM) with DM masses $m_X \sim \mathcal{O}(1 - 100)$ keV from leptonic decays $M\rightarrow \ell \barν_\ell + X$, where $M=B^\pm, D^\pm, D_s^\pm$ is a heavy meson state. We focus on two cases where $X$ denotes either a light pseudoscalar (axion-like), or a light vector state that couples to the standard model (SM) through kinetic mixing. We note that for a small DM mass these decays are separately sensitive to DM couplings to quarks, but not its mass.

Indirect Signatures of Type I See-Saw Scenarios

description: We consider the low energy constraints that can be applied to type I see-saw extensions of the Standard Model in which the right-handed neutrinos are taken at the electroweak scale. In the reported scenarios, the flavour structure of the charged current and neutral current weak interactions of the Standard Model leptons with the heavy right-handed neutrinos is essentially determined by the neutrino oscillation parameters. In this case, correlations among different measurable phenomena in the lepton sector may provide compelling indirect evidence of low energy see-saw mechanism of neutrino mass generation.

Arbitrary control of multiple-qubit systems in the symmetric Dicke subspace
Creators: name: Zheng, Shi-Biao
Publisher: name: arXiv
Year: 2012
Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: We discuss a general physical mechanism for arbitrary control of the quantum states of multiple qubits in the symmetric Dicke subspace. The qubit-qubit coupling leads to unequal energy spacing in the symmetric Dicke subspace. This allows one to manipulate a prechosen transition with an external driving source, with other transitions remaining off-resonant. Any entangled state in the symmetric Dicke subspace can be created from the initial ground state by tuning the driving source. We illustrate the idea in cavity QED, but it should be applicable to other related systems.
Core-collapse model of broadband emission from SNR RX J1713.7-3946 with thermal X-rays and Gamma-rays from escaping cosmic rays

description: We present a spherically symmetric, core-collapse model of SNR RX J1713.7-3946 that includes a hydrodynamic simulation of the remnant evolution coupled to the efficient production of cosmic rays (CRs) by nonlinear diffusive shock acceleration (DSA). High-energy CRs that escape from the forward shock (FS) are propagated in surrounding dense material that simulates either a swept-up, pre-supernova shell or a nearby molecular cloud. The continuum emission from trapped and escaping CRs, along with the thermal X-ray emission from the shocked heated ISM behind the FS, integrated over the remnant, is compared against broadband observations. Our results show conclusively that, overall, the GeV-TeV emission is dominated by inverse-Compton from CR electrons if the supernova is isolated regardless of its type, i.e., not interacting with a >>100 Msun shell or cloud. If the SNR is interacting with a much larger mass >10^4 Msun, pion-decay from the escaping CRs may dominate the TeV emission, although a precise fit at high energy will depend on the still uncertain details of how the highest energy CRs are accelerated by, and escape from, the FS. Based on morphological and other constraints, we consider the 10^4 Msun pion-decay scenario highly unlikely for SNR RX J1713.7-3946 regardless of the details of CR escape. Importantly, even though CR electrons dominate the GeV-TeV emission, the efficient production of CR ions is an essential part of our leptonic model.
