Kristallkieselhölzer aus dem basalen Schilfsandstein des württembergischen Keupers (km2), Trias
Creators: name: Nikel, Siegfried
Publisher: name: Jahreshefte der Gesellschaft für Naturkunde in Württemberg
Year: 2004

description: Aus dem basalen Schilfsandstein (Stuttgart-Gruppe, km2) konnten in den vergangenen Jahren eine ganze Reihe von Kieselhölzern geborgen werden. Das Fundgebiet liegt nahe der Ortschaft Kottspiel (Nordwürttemberg). Der basale Teil des Schilfsandsteins ist in der Umgebung von Kottspiel als konglomeratischer Sandstein ausgebildet, der aufgearbeitete Gesteinsfragmente zusammen mit permineralisiertem Holz und Wirbeltierknochen enthält. Der vorliegende Beitrag beschreibt die Lokalität, in der die Hölzer eingebettet und mit SiO2 permineralisiert wurden. Auf Grund der Einbettung der Treibhölzer über einem wasserundurchlässigen Tonhorizont kam es zu einer hohen Si(OH)4-Konzentration im Grundwasserstrom. Das sich zersetzende Holz und die entstandenen kleineren und größeren Fäulnishohlräume, Schwundrisse und Ritzen wurden mit Kieselsäure Si(OH)4 verfüllt. In einigen Hölzern herrschten optimale Bedingungen für die syngenetische Entstehung von permineralisiertem Holz, Quarzkristallrasen, radialstrahligen Sphärolithen, Tracheiden-Holosphärolithen, Festungsachaten und Chalcedonvarietäten. Der vorliegende Beitrag beschreibt und dokumentiert diese Kristallisationphänomene. Beschrieben werden ferner makroskopisch und mikroskopisch erkennbare holzanatomische Details von zwei verschiedenen Dadoxylon-Holztypen.

Abelian Chern-Simons Theory for the Fractional Quantum Hall Effect in Graphene
Creators: name: Fräßdorf, Christian

description: We develop a theory for the pseudorelativistic fractional quantum Hall effect in graphene, which is based on a multicomponent abelian Chern-Simons theory in the fermionic functional integral approach. Calculations are performed in the Keldysh formalism, directly giving access to real-time correlation functions at finite temperature. We obtain an exact effective action for the Chern-Simons gauge fields, which is expanded to second order in the gauge field fluctations around the mean-field solution. The one-loop fermionic polarization tensor as well as the electromagnetic response tensor in random phase approximation are derived, from which we obtain the Hall conductivities for various FQH states, lying symmetrically around charge neutrality.
Schwankende Umweltbedingungen des südwestdeutschen Oberjura dokumentiert in Kalk-Mergel-Wechselfolgen

description: Die Entstehung von Kalk-Mergel-Wechselfolgen, wie man sie so auffallend im Oberjura („Malm“) von Südwestdeutschland findet, ist ein seit langem diskutiertes, jedoch immer noch kontroverses Thema. Sowohl die Entstehung des rhythmischen Wechsels von Kalken und Mergeln (die sog. „Couplets“), als auch die großmaßstäblichen Trends von mehr kalkigen und mehr mergeligen Abschnitten der Oberjura-Abfolge (Impressamergel-, Wohlgebankte Kalke- und Lacunosamergel-Formationen) wurde in zahlreichen Arbeiten thematisiert. Dagegen hat die Entstehung der Variabilität mittleren Maßstabes, d. h. von im Meterbereich wechselnden Kalk- und Mergel-dominierten Bereichen („Bündel“), bislang deutlich weniger Beachtung gefunden. Auf diesen mittleren Maßstab konzentrieren wir uns hier. Ein Grundproblem bei der Entzifferung von Umweltinformation in Karbonatabfolgen ist in der Regel eine starke diagenetische Überprägung, die insbesondere von der Umwandlung metastabiler Karbonatphasen (z.B. Aragonit) in diagenetisch stabile (Calcit) herrührt. Dadurch wird unter anderem ein Verlust der Information über die ursprüngliche Mineralogie verursacht. Gerade in der mineralogischen Zusammensetzung der Ausgangssedimente, und insbesondere im primären Aragonitgehalt spiegeln sich jedoch die Umweltbedingungen zur Zeit der Ablagerung wider. In der vorliegenden Arbeit stellen wir eine Methode vor, mit der die Ausgangsmineralogie rekonstruiert werden kann, und diskutieren die Paläoumwelt-Information, die in den Bündeln überliefert ist. Dazu bedienen wir uns eines neuen, von uns entwickelten Modells zur Rekonstruktion der primären mineralogischen Zusammensetzung solcher Abfolgen am Beispiel des Oberjura von SW-Deutschland (Steinbruch Neuffen). Mit diesem Ansatz werden Schwankungen des Eintrags von Karbonatmaterial aus angrenzenden flachmarinen Plattformen sichtbar, die bislang unbekannt waren, und die sich als Änderungen der biogenen Karbonat-Produktivität interpretieren lassen. Dadurch kann das Bild der schwankenden Umweltbedingungen im süddeutschen Jurameer zur Zeit der Ablagerung der Impressamergel-, Wohlgebankte Kalke- und Lacunosamergel-Formationen rekonstruiert werden.

description: Analyzing DISTO data of $pp -> p Lambda K^+$ at $T_p = 2.50$ and 2.85 GeV to populate a previously reported X(2265) resonance with $M_X = 2267$ MeV/$c^2$ and $Gamma_X = 118$ MeV at 2.85 GeV, we found that the production of X(2265) at 2.50 GeV is much less than that at 2.85 GeV (less than 10%), though it is expected from a kinematical consideration to be produced as much as 33% of that at 2.85 GeV. The small population of X(2265) at 2.50 GeV is consistent with the very weak production of Lambda (1405) at the same incident energy toward its production threshold, thus indicating that Lambda (1405) plays an important role as a doorway state for the formation of X(2265).

description: Estimating causal interactions in complex dynamical systems is an important problem encountered in many fields of current science. While a theoretical solution for detecting the causal interactions has been previously formulated in the framework of prediction improvement, it generally requires the computation of high-dimensional information functionals -- a situation invoking the curse of dimensionality with increasing network size. Recently, several methods have been proposed to alleviate this problem, based on iterative procedures for assessment of conditional (in)dependences. In the current work, we bring a comparison of several such prominent approaches. This is done both by theoretical comparison of the algorithms using a formulation in a common framework, and by numerical simulations including realistic complex coupling patterns. The theoretical analysis highlights the key similarities and differences between the algorithms, hinting on their comparative strengths and weaknesses. The method assumptions and specific properties such as false positive control and order dependence are discussed. Numerical simulations suggest that while the accuracy of most of the algorithms is almost indistinguishable, there are substantial differences in their computational demands, ranging theoretically from polynomial to exponential complexity, and leading to substantial differences in computation time in realistic scenarios depending on the density and size of networks. Based on analysis of the algorithms and numerical simulations, we propose a hybrid approach providing competitive accuracy with improved computational efficiency.

description: Patients with Alzheimer's disease (AD) display a multiplicity of cognitive deficits in domains such as memory, language, and attention, all of which can be clearly linked to the underlying neuropathological alterations. The typical degenerative changes occur early on in the disease in the temporal–parietal lobes, with other brain regions, such as the frontal cortex, becoming more affected as the disease progresses. In light of the importance of the parietal cortex in mediating visuospatial attentional processing, in the present study, we investigated a deficit in covert orienting of visual attention and its relationship to cortical hypoperfusion in AD. We characterized the visual attentional profile of 21 AD patients, relative to that of 26 matched normal individuals, and then assessed the correspondence between behavior and hypoperfusion, as measured by regional cerebral blood flow using SPECT. Relative to controls, the AD group demonstrated a unilateral attentional deficit, with disproportionate slowing in reorienting attention to targets in the left compared to the right hemispace, especially following an invalid peripheral cue. Furthermore, even in the presence of bilateral pathology typical of AD, there was a positive correlation between this unilateral attentional disorder and the magnitude of the right superior parietal lobe hypoperfusion. The association of the altered attentional processing profile (i.e., greater difficulty disengaging attention from right-sided stimuli) with right-hemisphere-predominant hypoperfusion not only confirms the critical role of the right parietal lobe in covert attentional orienting but, more importantly, identifies a potential locus of the behavioral alterations in visuospatial processing in AD.

The Galactic Center Region Gamma Ray Excess from A Supersymmetric Leptophilic Higgs Model

Year: 2011
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: In a recent paper by Hooper and Goodenough, data from the Fermi Gamma Ray Telescope was analyzed and an excess of gamma rays was claimed to be found in the emission spectrum from the Galactic Center Region. Hooper and Goodenough suggest that the claimed excess can be well explained by 7-10 GeV annihilating dark matter with a power law density profile if the dark matter annihilates predominantly to tau pairs. In this paper we present such a dark matter model by extending the MSSM to include four Higgs doublets and one scalar singlet. A Z2 symmetry is imposed that enforces a Yukawa structure so that the up quarks, down quarks, and leptons each receive mass from a distinct doublet. This leads to an enhanced coupling of scalars to leptons and allows the model to naturally achieve the required phenomenology in order to explain the gamma ray excess. Our model yields the correct dark matter thermal relic density and avoids collider bounds from measurements of the Z width as well as direct production at LEP.

description: We summarize panchromatic Extragalactic Background Light data to place upper limits on the integrated near-infrared surface brightness (SB) that may come from Population III stars and possible accretion disks around their stellar-mass black holes (BHs) in the epoch of First Light, broadly taken from z$\simeq$7-17. Theoretical predictions and recent near-infrared power-spectra provide tighter constraints on their sky-signal. We outline the physical properties of zero metallicity Population III stars from MESA stellar evolution models through helium-depletion and of BH accretion disks at z$\gtrsim$7. We assume that second-generation non-zero metallicity stars can form at higher multiplicity, so that BH accretion disks may be fed by Roche-lobe overflow from lower-mass companions. We use these near-infrared SB constraints to calculate the number of caustic transits behind lensing clusters that the James Webb Space Telescope and the next generation ground-based telescopes may observe for both Population III stars and their BH accretion disks. Typical caustic magnifications can be $μ$$\simeq$10$^4$-10$^5$, with rise times of hours and decline times of $\lesssim$1 year for cluster transverse velocities of $v_{T}$$\lesssim$1000 km s$^{-1}$. Microlensing by intracluster medium objects can modify transit magnifications, but lengthen visibility times. Depending on BH masses, accretion-disk radii and feeding efficiencies, stellar-mass BH accretion-disk caustic transits could outnumber those from Population III stars. To observe Population III caustic transits directly may require to monitor 3-30 lensing clusters to AB$\lesssim$29 mag over a decade.

Genomic analysis and biology of a novel variant of Xylella fastidiosa subspecies multiplex infecting different host plants in Tuscany, Italy
Creators: name: Saponari Maria
Publisher: name: Zenodo
Year: 2019

description: Abstract: An increasing number of Xylella fastidiosa outbreaks associated with strains of the
 subspecies multiplex has been reported in southern Europe, currently the most common strains being
 detected in Corsica, the Balearic Islands, the province of Alicante (Spain) and, more recently, reported
 for the first time in Portugal and in the region of Tuscany (northen Italy). The Tuscany outbreak raised
 major concerns, being associated with a new variant of X. fastidiosa subsp. multiplex, characterised
 as sequence type ST87, capable of infecting, among the others, almond. Although this sequence type
 is closely related to the more common ST6 and ST7 variants, remarkable differences were recorded
 when culturing the ST87 isolates on different media as well as when comparing their draft genomes. In
 contrast to the majority of the strains of the subspecies multiplex, the ST87 isolates grow on PD3 solid
 medium, a peculiar feature described for a few and highly virulent strains associated with almond leaf
 scorch disease in North America (Almeida and Purcell, 2003). Analyses based on core genome
 alignments and single nucleotide polymorphisms of currently available Xylella genomes show they are
 genetically related to strains previously characterised in North America, but in a separate clade from
 strains of the subspecies multiplex previously sequenced in Europe, supporting the hyphothesis that
 they originate from a distinct introduction that occured in Europe. Pathogenicity tests on Prunus spp.
 and grapes are ongoing to assess the virulence and the host range of this newly discovered variant of
 X. fastidiosa.

description: The spread of computer based instructional materials makes it important to determine the relative merits and effects of virtual materials vs. physical materials in early science instruction. In this paper we first lay out a framework for comparing key aspects of this virtual-physical issue, and then we describe three studies addressing it. In two studies with middle school children we found that children using virtual and physical materials made equally large gains in their knowledge while learning a complex procedure (control of variables) under conditions of direct instruction (Study 1) and while learning about specific physical effects in a engineering design challenge in a discovery learning content (Study 2). These results suggest that simply replacing the physical materials with virtual materials does not affect the amount of learning or transfer when other aspects of the instruction are preserved. In the third study we describe our progress in creating a virtual tutor for teaching experimental design procedures and concepts to middle school children.

description: In order to calculate correlation functions of the chiral Potts model, one only needs to study the eigenvectors of the superintegrable model. Here we start this study by looking for eigenvectors of the transfer matrix of the periodic tau_2(t)model which commutes with the chiral Potts transfer matrix. We show that the degeneracy of the eigenspace of tau_2(t) in the Q=0 sector is 2^r, with r=(N-1)L/N when the size of the transfer matrix L is a multiple of N. We introduce chiral Potts model operators, different from the more commonly used generators of quantum group U-tilde_q(sl-hat(2)). From these we can form the generators of a loop algebra L(sl(2)). For this algebra, we then use the roots of the Drinfeld polynomial to give new explicit expressions for the generators representing the loop algebra as the direct sum of r copies of the simple algebra sl(2).

description: Virtual reality (VR) has finally come of age for serious applications in the behavioral neurosciences. After capturing the public imagination a decade ago, enthusiasm for VR flagged due to hardware limitations, an absent commercial market and manufacturers who dropped the mass-market products that normally drive technological development. Recently, however, improvements in computer speed, quality of head-mounted displays and wide-area tracking systems have made VR attractive for both research and real-world applications in neuroscience, cognitive science and psychology. New and exciting applications for VR have emerged in research, training, rehabilitation, teleoperation, virtual archeology and tele-immersion.

description: We propose a new type of Dzyaloshinskii-Moriya (DM) interactions which act on high-rank multipolar moments such as quadrupolar and octupolar moments. Here we consider 5d1 systems with broken spatial inversion symmetry, where the interplay of electron correlation, the spin-orbit coupling, and inversion symmetry breaking plays a crucial role. Using a numerical diagonalization on a two-site multiorbital Hubbard model, we reveal that anti-symmetric products of multipole operators have finite expectation values, indicating the existence of DM interactions for multipoles. We also find that the spin-orbit coupling dependences of DM interactions for multipoles are significantly different depending on the lattice structure. Finally, we discuss the numerical results for small and large spin-orbit coupling region by using perturbative analysis.

description: Cancer is a world-famous deadly disease. According to the World Health Organization (WHO), cancer is the second leading cause of death globally and is responsible for an estimated 9.6 million deaths in 2018. One well-known technique for cancer detection is the DNA microarray technique. DNA microarray technology provides an opportunity for researchers to analyze thousands of gene expression profiles at the same time to determine whether a person has cancer or not. However, one of the problems in DNA microarray data is the large number of features that require feature selection. In overcoming these problems, this study will use the feature selection Support Vector Machine-Recursive Feature Elimination (SVM-RFE) and Chi-Square and use the Naïve Bayes classification method. The accuracy results from using feature selection with those that are not will be compared. The accuracy between using the two feature selection methods will also be compared to find which feature selection method is better when combined with the Naïve Bayes classification method. To get an overall picture of the performance comparison, this study also considers precision, recall, and F1-score. The best accuracy results obtained were 100% lung cancer data with SVM-RFE and Chi-Square, 99.6% ovarian cancer with SVM-RFE, 93.7% breast cancer with SVM-RFE, and 90% colon cancer with SVM- RFE.

Here we describe the efficient implementation of analytic BOPs in the BOPfox program and library. We discuss the integration of the underlying non-magnetic, collinear-magnetic and noncollinear-magnetic tight-binding models that are evaluated by the analytic BOPs. We summarize the flow of an analytic BOP calculation including the determination of self-returning paths for computing the moments, the self-consistency cycle, the estimation of the band-width from the recursion coefficients, and the termination of the BOP expansion. We discuss the implementation of the calculations of forces, stresses and magnetic torques with analytic BOPs. We show the scaling of analytic BOP calculations with the number of atoms and moments, present options for speeding up the calculations and outline different concepts of parallelisation. In the appendix we compile the implemented equations of the analytic BOP methodology and comments on the implementation. This description should be relevant for other implementations and further developments of analytic bond-order potentials.

description: In this paper, we review the low energy electronic structure of the kinetic energy driven d-wave cuprate superconductors. We give a general description of the charge-spin separation fermion-spin theory, where the constrained electron is decoupled as the gauge invariant dressed holon and spin. In particular, we show that under the decoupling scheme, the charge-spin separation fermion-spin representation is a natural representation of the constrained electron defined in a restricted Hilbert space without double electron occupancy. Based on the charge-spin separation fermion-spin theory, we have developed the kinetic energy driven superconducting mechanism, where the superconducting state is controlled by both superconducting gap parameter and quasiparticle coherence. Within this kinetic energy driven superconductivity, we have discussed the low energy electronic structure of the single layer and bilayer cuprate superconductors in both superconducting and normal states, and qualitatively reproduced all main features of the angle-resolved photoemission spectroscopy measurements on the single layer and bilayer cuprate superconductors. We show that the superconducting state in cuprate superconductors is the conventional Bardeen-Cooper-Schrieffer like with the d-wave symmetry, so that the basic Bardeen-Cooper-Schrieffer formalism with the d-wave gap function is still valid in discussions of the low energy electronic structure of cuprate superconductors, although the pairing mechanism is driven by the kinetic energy by exchanging spin excitations. We also show that the well pronounced peak-dip-hump structure of the bilayer cuprate superconductors in the superconducting state and double-peak structure in the normal state are mainly caused by the bilayer splitting.

description: Cosmetics and beauty products (including skincare) are the products used as body care or face care and used to accentuate the body alure. A product could give diverse sentiment to the consumers including positive and negative sentiment. Many consumers of beauty products are sharing their reviews to help other consumers to find the right products to buy and to give feedback to the brand of the beauty product itself. The number of reviews is inversely proportional to the lack of opinion identification towards product’s aspects. Hence, a study has been conducted to analyze beauty products reviews as toner, serum, sun protection, and exfoliator. The analysis process is conducted aspect based to determine sentiment towards aspect of beauty products based on the reviews. The result is addressed to people using skincare and beauty product brands in deducting consumer’s opinion. The solution to this problem is by using Random Forest with hyperparameters tuning as classification method, and TF-IDF and n-gram as feature extraction methods. The multi-aspect sentiment analysis in this study obtained highest accuracy for 90.48%, precision for 87.27%, recall for 70.13%, and F1-Score for 71.77%.

description: We propose a new approach to measuring persistent currents in normal metal rings. By integrating micron-scale metal rings into sensitive micromechanical cantilevers and using the cantilevers as torque magnetometers, it should be possible to measure the rings' persistent currents with greater sensitivity than the SQUID-based and microwave resonator-based detectors used in the past. In addition, cantilever-based detectors may allow for measurements in a cleaner electromagnetic environment. We have fabricated ultra sensitive cantilevers with integrated rings and measured their mechanical properties. We present an estimate of the persistent current sensitivity of these cantilever-based detectors, focusing on the limits set by the cantilever's Brownian motion and the shot noise in the laser interferometer that monitors the cantilever.

description: Cancer is a deadly disease caused by abnormal growth of tissue cells that are not controlled in the body. In 2018, according to Globocan data, the number of cancer sufferers has increased from the previous years which was 18.1 million people, with a mortality rate of 9.6 million. In recent years, cancer prediction using DNA microarrays data can help medical experts in analyzing whether a person has cancer or not. DNA microarray data have very large and complex gene expression, therefore a dimensional reduction method is needed. Then, the dimension reduction results will be used for classification into types of cancer or not. In this paper, Principal Component Analysis (PCA) is used as a feature extraction to reduce dimension and Functional Link Neural Network as a classifier. Based on the simulation, the average of accuracy using the FLNN and PCA about 76.08%. Keywords: cancer detection, Microarray data, Functional Link Neural Network, Principal Component Analysis.

description: Conversational recommender system created for helping users in searching information in a domain by using conversational mechanism. These systems help user to get recommendation by selecting items that most suitable to user’s preference by asking user needed. The recommendations generated by eliciting user’s experience e.g. his favourite movies, actor and director and then gives the item that match their interest. There are many methods to get the suitable recommendation that match the user’s preference. In this paper, we use ontology which represents knowledge to get result of recommendation that fit to user preference by using knowledge-based filtering to determine the user’s need. Our system has been implemented for movie domain. We test our system performance by studying user's perception.

description: The concept of subgroup commutativity degree of a finite group $G$ is arising interest in several areas of group theory in the last years, since it gives a measure of the probability that a randomly picked pair $(H,K)$ of subgroups of $G$ satisfies the condition $HK=KH$. In this paper, a stronger notion is studied and relations with the commutativity degree are found.

description: We give simple homological conditions for a rational homology 3-sphere Y to have infinite order in the rational homology cobordism group, and for a collection of rational homology spheres to be linearly independent. These translate immediately to statements about knot concordance when Y is the branched double cover of a knot, recovering some results of Livingston and Naik. The statements depend only on the homology groups of the 3-manifolds, but are proven through an analysis of correction terms and their behavior under connected sums.

On the nature of steady states of spin distributions in the presence of spin-orbit interactions

description: In the presence of spin-orbit interactions, the steady state established for spin distributions in an electric field is qualitatively different from the steady state for charge distributions. This is primarily because the steady state established for spin distributions involves spin precession due to spin-orbit coupling. We demonstrate in this work that the spin density matrix in an external electric field acquires two corrections with different dependencies on the characteristic momentum scattering time. One part is associated with conserved spins, diverges in the clean limit and is responsible for the establishment of a steady-state spin density in electric fields. Another part is associated with precessing spins, is finite in the clean limit and is responsible for the establishment of spin currents in electric fields. Scattering between these distributions has important consequences for spin dynamics and spin-related effects in general, and explains some recent puzzling observations, which are captured by our unified theory.
