THE ATHYRIDOIDS OF THE TRANSITIONAL BEDS BETWEEN BELLEROPHON AND WERFEN FORMATIONS (UPPERMOST PERMIAN, SOUTHERN ALPS, ITALY)
Creators: name: POSENATO, RENATO
Publisher: name: Università degli Studi di Milano
Year: 2001

description: The transitional beds between Bellerophon and Werfen Formations, few centimetres thick and latest Permian in age, contain a brachiopod fauna with a relatively rich athyridoid assemblage, among which Janiceps is the most common and characteristic genus. The internal morphology of the type species (J. peracuta) is here described for the first time, and a taxonomical revision of the South Alpine species is proposed. The new subfamily Janicepsinae is proposed, which contains Janiceps and the new genus Comelicothyris. Among the latter genus, Comelicothyris laterosulcata n. sp. is suggested. Lectotypes are selected and illustrated for Spirigera janiceps Stache, S. confinalis Stache, S. bipartita Stache, S. ? archimedis Stache, Spirifer ? sextensis Stache, Athyris irregularis Merla, A. semilunaris Merla, and A janiceps var globulus Merla. The athyridoids of the transitional beds are characterized by a broad morphological variability which induced past authors to create many species and ìvarietiesî generally on the bais of a single or few individuals. As concerns Janiceps, only four species-versus the 14 species and 7 ìvarietiesî cited in the literature of the Souther Alps-are here considered valid (J. peracuta (Stache), J. cadorica (Stache), J. papilio (Stache), and J. bipartita (Stache)). Besides other four species are identified here; these are Comelicothyris recticardinis (Merla), Septospirigerella ? sp., Spirigerellinae gen. et sp. indet., and Comelicania merlai Posenato.

description: We consider triad dynamics as it was recently considered by Antal \emph{et al.} [T. Antal, P. L. Krapivsky, and S. Redner, Phys. Rev. E {\bf 72}, 036121 (2005)] as an approach to social balance. Here we generalize the topology from all-to-all to a regular one of a two-dimensional triangular lattice. The driving force in this dynamics is the reduction of frustrated triads in order to reach a balanced state. The dynamics is parameterized by a so-called propensity parameter $p$ that determines the tendency of negative links to become positive. As a function of $p$ we find a phase transition between different kind of absorbing states. The phases differ by the existence of an infinitely connected (percolated) cluster of negative links that forms whenever $p\leq p_c$. Moreover, for $p\leq p_c$, the time to reach the absorbing state grows powerlike with the system size $L$, while it increases logarithmically with $L$ for $p > p_c$. From a finite-size scaling analysis we numerically determine the critical exponents $β$ and $ν$ together with $γ$, $τ$, $σ$. The exponents satisfy the hyperscaling relations. We also determine the fractal dimension $d_f$ that fulfills a hyperscaling relation as well. The transition of triad dynamics between different absorbing states belongs to a universality class with new critical exponents. We generalize the triad dynamics to four-cycle dynamics on a square lattice. In this case, again there is a transition between different absorbing states, going along with the formation of an infinite cluster of negative links, but the usual scaling and hyperscaling relations are violated.

description: Conodonts from the latest Carnian - Middle Norian pelagic limestone and Late Norian - Rhaetian bedded chert-section at Hisaidani, southern Chichibu Belt, Shikoku, SW Japan, are described. Taxonomy of conodont-genera Metapolygnathus Hayashi, Ancyrogondolella Budurov, MockinaKozur and Misikella Kozur & Mock is discussed. Middle Norian Mockina sakurae n. sp., M. shamiseni n. sp. and Late Norian M. hisaidaniensisn. sp. are described.
The affinities of the Hisaidani - fauna are rather Tethyan. The Early - Middle Norian conodont-association at Hisaidani is dominated by Ancyrogondolella spatulata (Hayashi). Towards the Middle and Late Norian, affinities with Pacific taxa are present. The three new species provide also a provincial character that typifies the pre-accretionary Izanami plateau from which the rocks of Hisaidani were derived.

description: Beam-helicity asymmetries for the two-pion-photoproduction reaction gamma + p --> p pi+ pi- have been studied for the first time in the resonance region for center-of-mass energies between 1.35 GeV and 2.30 GeV. The experiment was performed at Jefferson Lab with the CEBAF Large Acceptance Spectrometer using circularly polarized tagged photons incident on an unpolarized hydrogen target. Beam-helicity-dependent angular distributions of the final-state particles were measured. The large cross-section asymmetries exhibit strong sensitivity to the kinematics and dynamics of the reaction. The data are compared with the results of various phenomenological model calculations, and show that these models currently do not provide an adequate description for the behavior of this new observable.

Furthermore, the singular and logarithmic tail contributions are calculated. We also consider the non--local tail contributions. Further steps towards the complete calculation are discussed and first comparisons are given to results in the literature.

description: This paper gives results for the spectrum, all allowed E1 radiative partial widths (and some important M1 widths) and all open-charm strong decay amplitudes of all 40 c-cbar states expected up to the mass of the 4S multiplet, just above 4.4 GeV. The spectrum and radiative widths are evaluated using two models, the relativized Godfrey-Isgur model and a nonrelativistic potential model. The electromagnetic transitions are evaluated using Coulomb plus linear plus smeared hyperfine wavefunctions, both in a nonrelativistic potential model and in the Godfrey-Isgur model. The open-flavor strong decay amplitudes are determined assuming harmonic oscillator wavefunctions and the 3P0 decay model. This work is intended to motivate future experimental studies of higher-mass charmonia, and may be useful for the analysis of high-statistics data sets to be accumulated by the BES, CLEO and GSI facilities.

description: We have developed a linear scaling algorithm for calculating maximally-localized Wannier functions (MLWFs) using atomic orbital basis. An O(N) ground state calculation is carried out to get the density matrix (DM). Through a projection of the DM onto atomic orbitals and a subsequent O(N) orthogonalization, we obtain initial orthogonal localized orbitals. These orbitals can be maximally localized in linear scaling by simple Jacobi sweeps. Our O(N) method is validated by applying it to water molecule and wurtzite ZnO. The linear scaling behavior of the new method is demonstrated by computing the MLWFs of boron nitride nanotubes.

description: We present inelastic neutron scattering data on highly overdoped Bi_2 Sr_2 Ca Cu_2 O_{8+δ} single crystals with superconducting transition temperature T_C=70 K and, for comparison, a nearly optimally doped crystal with T_C=87 K. In both samples, magnetic resonant modes with odd and even symmetry under exchange of the two CuO_2 layers in the unit cell are observed. In the overdoped sample, the linewidth of the odd mode is reduced compared with the optimally doped sample. This finding is discussed in conjunction with recent evidence for intrinsic inhomogeneities in this compound. The data on odd and even resonant excitations are otherwise fully consistent with trends established on the basis of data on YBa_2Cu_3O_{6+x}. This confirms the universality of these findings and extends them into the highly overdoped regime of the phase diagram.

description: We study the effect of clustering on the organization of cooperation, by analyzing the evolutionary dynamics of the Prisoner's Dilemma on scale-free networks with a tunable value of clustering. We find that a high value of the clustering coefficient produces an overall enhancement of cooperation in the network, even for a very high temptation to defect. On the other hand, high clustering homogeneizes the process of invasion of degree classes by defectors, decreasing the chances of survival of low densities of cooperator strategists in the network.

description: We perform stochastic simulations of the quantum Zeno and anti-Zeno effects for two level system and for the decaying one. Instead of simple projection postulate approach, a more realistic model of a detector interacting with the environment is used. The influence of the environment is taken into account using the quantum trajectory method. The simulation of the measurement for a single system exhibits the probabilistic behavior showing the collapse of the wave-packet. When a large ensemble is analysed using the quantum trajectory method, the results are the same as those produced using the density matrix method. The results of numerical calculations are compared with the analytical expressions for the decay rate of the measured system and a good agreement is found. Since the analytical expressions depend on the duration of the measurement only, the agreement with the numerical calculations shows that otherparameters of the model are not important.

Spatial and Temporal Taylor's Law in 1-Dim Chaotic Maps

description: By using low-dimensional chaos maps, the power law relationship established between the sample mean and variance called Taylor's Law (TL) is studied. In particular, we aim to clarify the relationship between TL from the spatial ensemble (STL) and the temporal ensemble (TTL). Since the spatial ensemble corresponds to independent sampling from a stationary distribution, we confirm that STL is explained by the skewness of the distribution. The difference between TTL and STL is shown to be originated in the temporal correlation of a dynamics. In case of logistic and tent maps, the quadratic relationship in the mean and variance, called Bartlett's law, is found analytically. On the other hand, TTL in the Hassell model can be well explained by the chunk structure of the trajectory, whereas the TTL of the Ricker model have a different mechanism originated from the specific form of the map.

Cosmological Parameters from the Comparison of the 2MASS Gravity Field with Peculiar Velocity Surveys

description: We compare the peculiar velocity field within 65 $h^{-1}$ Mpc predicted from 2MASS photometry and public redshift data to three independent peculiar velocity surveys based on type Ia supernovae, surface brightness fluctuations in ellipticals, and Tully-Fisher distances to spirals. The three peculiar velocity samples are each in good agreement with the predicted velocities and produce consistent results for $β_{K}=Ω\sbr{m}^{0.6}/b_{K}$. Taken together the best fit $β_{K} = 0.49 \pm 0.04$. We explore the effects of morphology on the determination of $β$ by splitting the 2MASS sample into E+S0 and S+Irr density fields and find both samples are equally good tracers of the underlying dark matter distribution, but that early-types are more clustered by a relative factor $b\sbr{E}/b\sbr{S} \sim 1.6$. The density fluctuations of 2MASS galaxies in $8 h^{-1}$ Mpc spheres in the local volume is found to be $σ\sbr{8,K} = 0.9$. From this result and our value of $β_{K}$, we find $σ_8 (Ω\sbr{m}/0.3)^{0.6} = 0.91\pm0.12$. This is in excellent agreement with results from the IRAS redshift surveys, as well as other cosmological probes. Combining the 2MASS and IRAS peculiar velocity results yields $σ_8 (Ω\sbr{m}^/0.3)^{0.6} = 0.85\pm0.05$.

description: We investigate roughening transitions in the context of transverse-field Ising models. As a modification of the transverse Ising model with short range interactions, which has been shown to exhibit domain wall roughening, we have looked into the possibility of a roughening transition for the case of long-range interactions, since such a system is physically realized in the insulator LiHoF4. The combination of strong Ising anisotropy and long-range forces lead naturally to the formation of domain walls but we find that the long-range forces destroy the roughening transition.

With this result we are able to extend the dichotomies of Bochi-Mañé and of Newhouse for flows with singularities. That is we obtain for a residual subset of the C^1 incompressible flows on 3-manifolds that: (i) either all Lyapunov exponents are zero or the flow is Anosov, and (ii) either the flow is Anosov or else the elliptic periodic points are dense in the manifold.

THE PLIOCENE DEPOSITS IN THE CENTRAL-EASTERN VALDELSA BASIN (FLORENCE, ITALY), REVISED THROUGH FACIES ANALYSIS AND UNCONFORMITY-BOUNDED STRATIGRAPHIC UNITS
Creators: name: BENVENUTI, MARCO

description: The Valdelsa Basin is one of the widest post-collisional basins developed in central Tuscany (Italy) since the late Miocene. More than 2,000 m of upper Miocene-Quaternary deposits fill the basin and1,000 of which, ascribed to the Pliocene, crop out extensively. In previous studies these deposits have been included in poorly defined lithostratigraphic schemes, and also a detailed chronologic calibration via biostratigraphic analysis has produced few results due to the paucity of biomarkers. In this study the Pliocene deposits have been subdividedinto eleven lithofacies associations, in turn included in five unconformity-bounded stratigraphic units (synthems) spanning in age from the uppermost Zanclean to most part of Piacenzian. Lithofacies associations, defined as the recurring vertical alternance of several basic lithofacies, are in fact recognized based on both the lithologic features and the sedimentary/bio-(marine to continental molluscs) facies content which formedin specific environments. Several depositional systems activated in the basin, from alluvial to fluvio-deltaic to paralic and inner shelf systems, in response to change of sediment supply and accommodation space. The Pliocene paleogeography of the portion of the basin considered in this study was characterized by the occurrence of a structural high that separated two distinctdepositional areas in theearly stage of the basin fill. A marine (delta front to inner shelf) area developed in the central part (Certaldo-Castelfiorentino area), while an alluvial plain was forming eastward (in the S. Casciano area). During the Piacenzian the basin was characterized by the progressive filling of a shallow marine area (central part) due to the southwestward progradation of fluvio deltaic systems.

description: We report magnetism in carbon doped ZnO. Our first-principles calculations based on density functional theory predicted that carbon substitution for oxygen in ZnO results in a magnetic moment of 1.78 $μ_B$ per carbon. The theoretical prediction was confirmed experimentally. C-doped ZnO films deposited by pulsed laser deposition with various carbon concentrations showed ferromagnetism with Curie temperatures higher than 400 K, and the measured magnetic moment based on the content of carbide in the films ($1.5 - 3.0 μ_B$ per carbon) is in agreement with the theoretical prediction. The magnetism is due to bonding coupling between Zn ions and doped C atoms. Results of magneto-resistance and abnormal Hall effect show that the doped films are $n$-type semiconductors with intrinsic ferromagnetism. The carbon doped ZnO could be a promising room temperature dilute magnetic semiconductor (DMS) and our work demonstrates possiblity of produing DMS with non-metal doping.

description: We theoretically study frustrated double ionization (FDI) of atoms subjected to intense circularly polarized laser pulses using a three-dimensional classical model. We find a novel "knee" structure of FDI probability as a function of intensity, which is similar to the intensity dependence of nonsequential double ionization probability. The observation of FDI is more favourable when using targets with low ionization potentials and short driving laser wavelengths. This is attributed to the crucial role of recollision therein, which can be experimentally inferred from the photoelectron momentum distribution generated by FDI. This work provides novel physical insights into FDI dynamics with circular polarization.

description: Upper Tertiary aeolian strata (Río Negro Formation) outcrop in extensive sea cliffs at the Northeast of Patagonia. These outcrops show deposits corresponding to a complete suite of aeolian and aeolian related sub-environments, and also provide excellent exposures to analyse the sedimentology and internal architecture from a sequence stratigraphic point of view. Field studies, supplemented withline-drawings of oblique photographs, allowed the recognition of seven aeolian depositional sequences within the succession, each one bounded by regional super surfaces (or deflation surfaces). Internally these aeolian sequences display a cyclic recurrence in facies, that yields a tentative genetic model for their evolution. As documented from field examples, each basic aeolian depositional sequence was deposited during a single aggradational period, and is bounded by unconformities related to degradational periods. Degradational periods are regional deflationary events, that resulted in deep-scoured to flat surfaces, characterised by erosion / non deposition in which the only recognised accumulation is isolated and large angular blocks of fine-grained aggregates, interpreted as residual remnants of deposits of the previous sequence. Aggradational periods are characterised by a near- continuous accumulations responsible for the sequence building. Differences in the aeolian sediment budget to the area and the rising rate of water table control the related facies types, and allow to discriminateearly and late aggradational sub-periods. Early aggradational sub-periods form under conditions of relatively fast rising water tables associated with moderate aeolian sediment budget, thus resulting in the development of extended wet interduneslaterally associated with aeolian dunes and dry interdunes. During late aggradational sub-periods, the depositional surface outdistanced the water table, and aeolian dunes and dry interdunes tend to predominate. This sub-period is also characterised by an upward tendency to stabilisation, evidenced by the common occurrence of palaeosols in upper levels. Although the preserved thickness of each aeolian sequence is closely related to the average subsidence rate, the internal facies evolution suggests an overall climatic control for their origin.

description: We study the uniformly weighted ensemble of force balanced configurations on a triangular network of nontensile contact forces. For periodic boundary conditions corresponding to isotropic compressive stress, we find that the probability distribution for single-contact forces decays faster than exponentially. This super-exponential decay persists in lattices diluted to the rigidity percolation threshold. On the other hand, for anisotropic imposed stresses, a broader tail emerges in the force distribution, becoming a pure exponential in the limit of infinite lattice size and infinitely strong anisotropy.

description: This work presents the LPMO (Learning Problems Modeling Ontology), an ontology for the domain oflearning problems that models the types of problems learners are faced with, their most importantdimensions (such as complexity, structure and abstractness), the types of their representations and solutionsand also the learner’s skills required to solve them. In general, the proposed ontology is an effort toformalize the domain of learning problems in order to enable its representation in a machine-processableway. Developing the ontology is a first step towards building adaptive and interoperable web-basedenvironments for problem-based learning, which can support a variety of learners in a variety of problemsolvingtasks. The paper presents the key aspects of the domain and the proposed ontology and it furtherexplores how the ontology can be used in technology-enhanced learning environments that store, manageand share problem-based learning information concerning different kinds of learning problems and theirinstantiations.

description: In order to identify the exact criteria for the formation of two-ring structures in galaxies, we studied the issue of gravitational instability of the corresponding structural vibration modes against the background of a composite disk model [1-3], which has an exact nonlinear law of nonstationarity. Nonstationary analogs of dispersion equations for the given structural vibration modes of the model are derived and the results of their analysis are obtained. A comparative analysis of the increments of instabilities of ring-like oscillation modes is carried out to determine the dependence of their characteristic times of manifestation on the main physical parameters of the model.

description: We study the classical and quantum cosmology of a 4+1-dimensional space-time with a non-zero cosmological constant coupled to a self interacting massive spinor field. We consider a spatially flat Robertson-Walker universe with the usual scale factor $R(t)$ and an internal scale factor $a(t)$ associated with the extra dimension. For a free spinor field the resulting equations admit exact solutions, whereas for a self interacting spinor field one should resort to a numerical method for exhibiting their behavior. These solutions give rise to a degenerate metric and exhibit signature transition from a Euclidean to a Lorentzian domain. Such transitions suggest a compactification mechanism for the internal and external scale factors such that $a\sim R^{-1}$ in the Lorentzian region. The corresponding quantum cosmology and the ensuing Wheeler-DeWitt equation have exact solutions in the mini-superspace when the spinor field is free, leading to wavepackets undergoing signature change. The question of stabilization of the extra dimension is also discussed.

Magnetic Reynolds number dependence of reconnection rate and flow structure of the self-similar evolution model of fast magnetic reconnection
Creators: name: Nitta, Shin-ya
Publisher: name: arXiv
Year: 2005
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: This paper investigates Magnetic Reynolds number dependence of the ``self-similar evolution model'' (Nitta et al. 2001) of fast magnetic reconnection. I focused my attention on the flow structure inside and around the reconnection outflow, which is essential to determine the entire reconnection system (Nitta et al. 2002). The outflow is consist of several regions divided by discontinuities, e.g., shocks, and it can be treated by a shock-tube approximation (Nitta 2004). By solving the junction conditions (e.g., Rankine-Hugoniot condition), the structure of the reconnection outflow is obtained. Magnetic reconnection in most astrophysical problems is characterized by a huge dynamic range of its expansion ($sim 10^7$ for typical solar flares) in a free space which is free from any influence of external circumstances. Such evolution results in a spontaneous self-similar expansion which is controlled by two intrinsic parameters: the plasma-$beta$ and the magnetic Reynolds number. The plasma-$beta$ dependence had been investigated in our previous paper. This paper newly clarifies the relation between the reconnection rate and the inflow structure just outside the Petschek-like slow shock: As the magnetic Reynolds number increases, strongly converging inflow toward the Petschek-like slow shock forms, and it significantly reduces the reconnection rate.

description: Was bedeuten Megatrends wie der Klimawandel für die Rolle von Planern? Wie verändert sich planerisches Handeln während der Aufstellung von verbindlichen Plänen? Bekannte Ideen, Verhaltens- und Denkweisen oder historische Vorläufer müssen geprüft und verändert werden, neue Verhaltensweisen und Rollenverständnisse hinzugefügt werden. Räumliche Planung als absichtsvolle und in die Zukunft gerichtete Tätigkeit in komplexen realen Situationen ist dafür auf kontextbezogene Strategien zur Reduktion von Unsicherheit und Komplexität angewiesen. Einerseits in Bezug auf zur Verfügung stehende Informationen und Zusammenhänge, anderseits in Verbindung mit Wertvorstellungen, raumwirksamen Entscheidungen anderer Akteure, Zukunftsprognosen und Wirkungen heutiger Handlungen. Das vorliegende Buch zeichnet Rollenverständnisse in der Planungstheorie nach und fügt sie in einem Prozessmodell zusammen. Dieses wird zur empirischen Überprüfung auf die Aufstellung des neuen Regionalplans Ruhr durch den Regionalverband Ruhr (RVR) angewendet. Dieses Buch bietet eine umfassende Grundlage zur Reflexion, Selbstreflexion und Verbesserung des eigenen planerischen Handelns.

description: Στόχος της εργασίας είναι η μελέτη των επιδράσεων της δυτικής και ειδικότερα της βενετικής τέχνης, στη ζωγραφική των μεταβυζαντινών εικόνων του πρώτου αιώνα μετά την Αλωση. Σε πρώτο επίπεδο, ερευνάται το κοινωνικοπολιτικό υπόβαθρο μέσα στο οποίο νοείται ο προσανατολισμός της τέχνης των εικόνων προς τη Δύση και εξετάζονται οι βασικοί παράγοντες που συντέλεσαν στη γένεση και διατήρηση της εκτελεκτικιστικής τεχνοτροπίας : οι δημιουργοί και οι αγοραστές. Κατόπιν, εντοπίζονται τα θεμελιώδη χαρακτηριστικά του ιταλοκρητικού καλλιτεχνικού ύφους και υπογραμμίζεται η συμβολή της βενετσιάνικης ζωγραφικής στη διαμόρφωσή τους. Τέλος, παρατίθεται ένας εκτενής κριτικός κατάλογος των δυτικότροπων έργων που αποτέλεσαν αντικείμενο της εργασίας
description: Aim of the thesis is the study of the various influences of european , and more specifically venetian art, on post-byzantne icon-painting during the first century after the fall of Constantinople. There has been an effort to investigate the sociopolitical background which explains the orientation of icon-painting towards western art, as well as to point out the primordial factors that conduced to the creation and perpetuation of such an eclectic style : the painters and patrons. Moreover, there has been an attempt to define the fundamental characteristics of the so called italo-cretan style and also to stress the contribution of venetian painting to its formation. Last but not least, all the icons included in the thesis are presented in a critical and illustrated catalogue
THE POGGIO ROSSO LOCALITY CALIBRATED TO THE END-PLIOCENE AND ITS SIGNIFICANCE FOR DATING THE LATE VILLAFRANCHIAN MAMMAL FAUNAS OF THE UPPER VALDARNO, CENTRAL ITALY

description: A rich deposit of mammals was discovered in September 1995 at Poggio Rosso, the hill-top of the Matassino clay pit, in the Upper Valdarno Basin, 30 m above another deposit whose local fauna was assembled 30 years earlier. This latter provided the Matassino Locality, assigned to the beginning of the late Villafranchian Mammal Neogene age on the basis of its affinity with the Olivola faunal unit, which was also taken to represent the earliest assemblage in the Pleistocene. The paleomagnetic record in the short section across the Matassino Locality revealed the Olduvai chron, which was imprinted also in the fossil-bearing stratum of Poggio Rosso, so constraining both their ages to the latest Pliocene. The Poggio Rosso fauna, yet to be paleontologically determined, and the other late Villafranchian faunas collected in the Upper Valdarno from the Montevarchi complex fit a similar time span. Therefore, their magnetostratigraphically calibrated ages provide the time constraints for the biochronological relationships between faunas which can be tuned to several tie points for numerically evaluating their diversification steps during the whole Olduvai chron and shortly out of it.

description: Using finite gap methods, we find the leading order finite size corrections for an arbitrary number of giant magnons on physical strings, where the sum of the momenta is a multiple of 2π. Our results are valid for the Hofman-Maldacena fundamental giant magnons as well as their dyonic generalizations. The energy corrections turn out to be surprisingly simple, especially if all the magnons are fundamental, and at leading order are independent of the magnon flavors. We also show how to use the Bethe ansatz to find finite size corrections for dyonic giant magnons with large R-charges.
