description: The idea to simulate pedestrian flow by the application of fluid dynamics equations has a certain history in that field. This approach is based on the application of partial differential equations, which makes it a macroscopic method. The need to simulate several different species of pedestrians is a need from the start, which has not been matched very well by numerical simulations of macroscopic type. The basis of the description of non dense pedestrian movement by incompressible fluid flow models consists in the introduction of an empty phase as a species of a multiphase system of distinct phases.

description: We consider a generalization of the Connected Facility Location problem where clients may connect to open facilities via access trees shared by multiple clients. The task is to choose facilities to open, to connect these facilities by a core Steiner tree (of infinite capacity), and to design and dimension the access trees, such that the capacities installed on the edges of these trees suffice to simultaneously route all clients' demands to the open facilities. We assume that the available edge capacities are given by a set of different cable types whose costs obey economies of scale. The objective is to minimize the total cost of opening facilities, building the core Steiner tree among them, and installing capacities on the access tree edges. In this paper, we devise the first constant-factor approximation algorithm for this problem. We also present a factor 6.72 approximation algorithm for a simplified version of the problem where multiples of only one single cable type can be installed on the access edges.

description: Many statistical methods have been proposed in the last years for analyzing the spatial distribution of galaxies. Very few of them, however, can handle properly the border effects of complex observational sample volumes. In this paper, we first show how to calculate the Minkowski Functionals (MF) taking into account these border effects. Then we present a multiscale extension of the MF which gives us more information about how the galaxies are spatially distributed. A range of examples using Gaussian random fields illustrate the results. Finally we have applied the Multiscale Minkowski Functionals (MMF) to the 2dF Galaxy Redshift Survey data. The MMF clearly indicates an evolution of morphology with scale. We also compare the 2dF real catalog with mock catalogs and found that Lambda-CDM simulations roughly fit the data, except at the finest scale.

description: We examine when a matrix whose elements are differentiable functions in one variable commutes with its derivative. This problem was discussed in a letter from Issai Schur to Helmut Wielandt written in 1934, which we found in Wielandt's Nachlass. We present this letter and its translation into English. The topic was rediscovered later and partial results were proved. However, there are many subtle observations in Schur's letter which were not obtained in later years. Using an algebraic setting, we put these into perspective and extend them in several directions. We present in detail the relationship between several conditions mentioned in Schur's letter and we focus in particular on the characterization of matrices called Type 1 by Schur. We present several examples that demonstrate Schur's observations.

description: We propose and analyze two strategies for preconditioning linear operator equations that arise in PDE constrained optimal control in the framework of conjugate gradient methods.

We construct a preconditioner that yields favorable robustness properties with respect to critical parameters.

description: Various microorganisms and some mammalian cells are able to swim in viscous fluids by performing nonreciprocal body deformations, such as rotating attached flagella or by distorting their entire body. In order to perform chemotaxis, i.e. to move towards and to stay at high concentrations of nutrients, they adapt their swimming gaits in a nontrivial manner. We propose a model how microswimmers are able to autonomously adapt their shape in order to swim in one dimension towards high field concentrations using an internal decision making machinery modeled by an artificial neural network. We present two methods to measure chemical gradients, spatial and temporal sensing, as known for swimming mammalian cells and bacteria, respectively. Using the NEAT genetic algorithm surprisingly simple neural networks evolve which control the shape deformations of the microswimmer and allow them to navigate in static and complex time-dependent chemical environments. By introducing noisy signal transmission in the neural network the well-known biased run-and-tumble motion emerges. Our work demonstrates that the evolution of a simple internal decision-making machinery, which we can fully interpret and is coupled to the environment, allows navigation in diverse chemical landscapes. These findings are of relevance for intracellular biochemical sensing mechanisms of single cells, or for the simple nervous system of small multicellular organisms such as C. elegans.

Fig. 8
 Two stuffed specimens (one adult and one subadult), captured in the surroundings, were examined in the Basamfasal collection (cf. Masseti 2001, 2004). According to Abu Rabieh (1994, pers. comm.), there were numerous specimens in the Euphrates from Deir ez-Zor up to Abu Kamal (at the Iraqi border), Al Mayaddin and Doura Europos, but not in the north-westernmost area of Raqqa. Kock et al. (1994) reported the occurrence of this species from the Khabur valley, in north-eastern Syria. Additional data on the distribution of the species in eastern Syria were collected during a biological expedition organised inter alia by the National Museum (Natural History) of Prague in the period 11 June–7 July 1998. The occurrence of otters was confirmed from an island in the Euphrates at Doura Europos, from the site of Halabiyyeh and from Tell Sheikh, along the river Khabur, all sites in the district of Deir-ez-Zor (Uhrin et al. 2000). Data collected between 1989 and 1998 appear to indicate that a considerable population of otters is still present in this portion of eastern Syria, comprised between the Euphrates, its tributary the Khabur and the border with Iraq.
The carnivore is reported from the West Bank and northern Lebanon, and recent evidence is in favour of its presence in the western Bekaa valley and in the river Litani (Mounir R. Abi-Said 2008: pers. comm.). In neighbouring Israel otters are present in aquatic habitats and fishponds in the Hula Valley, in the northern Jordan River catchments and the Harod Valley (Dolev et al. 2006; Ben Ari et al. 2008); Guter et al. 2005; Guter et al. 2008). A single record from the Zvulun Valley and Carmel coastal area in 2000 suggests the existence of a remnant population along the coast, which may have become extinct (Dolev et al. 2006). New findings have indicated previously undocumented otter activity in the Golan Heights (Dolev et al. 2006).

Persistence in black hole lattice cosmological models

Year: 2020
Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)

description: Dynamical solutions for an evolving multiple network of black holes near a cosmological bounce dominated by a scalar field are investigated. In particular, we consider the class of black hole lattice models in a hyperspherical cosmology, and we focus on the special case of eight regularly-spaced black holes with equal masses when the model parameter $κ> 1$. We first derive exact time evolving solutions of instantaneously-static models, by utilizing perturbative solutions of the constraint equations that can then be used to develop exact 4D dynamical solutions of the Einstein field equations. We use the notion of a geometric horizon, which can be characterized by curvature invariants, to determine the black hole horizon. We explicitly compute the invariants for the exact dynamical models obtained. As an application, we discuss whether black holes can persist in such a universe that collapses and then subsequently bounces into a new expansionary phase. We find evidence that in the physical models under investigation (and particularly for $κ> 1$) the individual black holes do not merge before nor at the bounce, so that consequently black holes can indeed persist through the bounce.

description: The means applied for the macroscopic modeling of pedestrian crowd simulations have originally been designed to model systems in the field of physics. This physics-mathematics coevolved toolbox makes certain assumptions about the nature of the objects that are dealt with. A natural question that arises now, is how well these tools fit pedestrian crowd simulations which deal with "systems'' of interacting intelligent "particles''. In this article we try to shed some light on these questions and try to outline a possible modeling approach.

In the Levant the distribution of this mustelid is restricted to the northern areas of the region, including Lebanon (Serhal 1985; Harrison and Bates 1991) and northern Syria (Masseti 1995). In Palestine, for example, the species does not exist at present (Dayan and Tchernov 1988; Dayan 1989). It has not been reported from the northern Arabian peninsula since the Early Bronze Age (Boessneck 1977; Dayan and Tchernov 1988). In the course of this research it was possible to examine only one stuffed specimen on display in the Idlib museum. Thus, this site can be regarded as one of the southernmost stations of the weasel in the south-western Near East. Beyond this Levantine distribution gap in the southern Levant, the species occurs again in Egypt, along the Nile delta and valley, with a population characterised by large body size and regarded as almost completely commensal with man (Osborn and Helmy 1980).

description: Optical investigations on the dynamics of dense suspensions are challenging due to reduced optical accessibility. Furthermore, the suspension particle image size can strongly deviate from the optimal particle image size for PIV measurements. Optical accessibility can be achieved by refractive index matching of surface labelled suspension particles. This results in particle images that are transparent in the particle image center, but fluoresce at the particle image rim, resulting in ring-shaped particle images. In the present study the influence of particle image size of such ring-shaped particle images is compared with Gaussian and plateau-shaped particle images. Particles of Gaussian image shape result from fully labelled particles with small image diameters and are commonly used in PIV measurements. Such particles are also utilized for the determination of the continuous phase velocities in the experimental part of the present study. Monte Carlo simulations show that ring-shaped particle images have a superior behavior, i.e. they assume a reduced displacement estimation error for noisy as well as for noise-free image data, compared to Gaussian and plateau-shaped particle images. This is also true for large particle image diameters when particle images are intersected at interrogation window borders. Measurements are performed on a suspension containing 5 Vol.-% surface labelled, refractive index matched 60$μ$m PMMA particles. Simultaneously, $μ$PIV measurements of the carrier liquid flow are performed utilizing 1.19$μ$m fluorescent PS particles. Overall, the present study demonstrates theoretically and experimentally that the usage of suspension particles with ring-shaped images is suitable for $μ$PIV measurements to gain detailed insights into suspension bulk dynamics.
BIVALVES AND BRACHIOPODS NEAR THE PERMIAN-TRIASSIC BOUNDARY FROM THE BÜKK MOUNTAINS (BÁLVÁNY-NORTH SECTION, NORTHERN HUNGARY)

description: In the Bükk Mountains the Upper Permian is represented by the Nagyvisnyó Limestone, which contains very rich marine assemblages. It is overlain by the Gerennavár Limestone (uppermost Permian-Lower Triassic) which records the effects of the Permo-Triassic mass extinction with a dramatic decrease in diversity and abundance of fossils. The basal Gerennavár Limestone is represented by a clayey marl unit (basal beds) deposited in a quiet, low-energy marine environment below the storm wave-base, whose maximum thickness, about one meter, is recorded in the Bálvány-North section. From this locality a relatively diversified and abundant marine benthonic assemblage has been collected, and is here described. Bivalves are represented by: Bakevellia cf. ceratophaga (Schlotheim), ? Pterinopectinidae gen. et sp. indet., Eumorphotis lorigae sp. n., the most abundant species, Entolium piriformis (Liu) and Pernopecten latangulatus Yin. Brachiopods are less frequent, and the following four species have been identified: Spinomarginifera sp., Orthothetina ladina (Stache), Ombonia tirolensis (Stache) and Orbicoelia tschernyschewi (Likharew). An exact age of this fauna, based on conodonts, is not yet available, but the strong affinities with those of the lower Tesero Member (Dolomites) and the Lower Kathwai Member (Pakistan) suggest a latest Permian age (? Hindeodus praeparvus Zone). If so, the Bálvány-North section becomes one of the few in the world which records the last bioevents of the Palaeozoic.

A total of 14 magnetozones were observed. The Carnian-Norian boundary is placed in a thin stratigraphic interval between the last occurrence of Paragondolella nodosa and the first occurrence of Epigondolella abneptis. Data from Guri Zi are in substantial agreement with already published data from Silicka Brezova in Slovakia and Pizzo Mondello in Sicily, which complessively indicate that the conodont Carnian-Norian boundary, when magnetostratigraphically traced onto the Newark astrochronological polarity time scale (APTS), has an age of ~228-227 Ma.

description: We revisit the stellar velocity distribution in the Galactic bulge/bar region with APOGEE DR16 and {\it Gaia} DR2, focusing in particular on the possible high-velocity (HV) peaks and their physical origin. We fit the velocity distributions with two different models, namely with Gauss-Hermite polynomial and Gaussian mixture model (GMM). The result of the fit using Gauss-Hermite polynomials reveals a positive correlation between the mean velocity ($\bar{V}$) and the "skewness" ($h_{3}$) of the velocity distribution, possibly caused by the Galactic bar. The $n=2$ GMM fitting reveals a symmetric longitudinal trend of $|μ_{2}|$ and $σ_{2}$ (the mean velocity and the standard deviation of the secondary component), which is inconsistent to the $x_{2}$ orbital family predictions. Cold secondary peaks could be seen at $|l|\sim6^\circ$. However, with the additional tangential information from {\it Gaia}, we find that the HV stars in the bulge show similar patterns in the radial-tangential velocity distribution ($V_{\rm R}-V_{\rm T}$), regardless of the existence of a distinct cold HV peak. The observed $V_{\rm R}-V_{\rm T}$ (or $V_{\rm GSR}-μ_{l}$) distributions are consistent with the predictions of a simple MW bar model. The chemical abundances and ages inferred from ASPCAP and CANNON suggest that the HV stars in the bulge/bar are generally as old as, if not older than, the other stars in the bulge/bar region.

The development of spelling in deaf and hard of hearing children
Creators: name: Cupit, Jennifer Margot
Publisher: name: University of British Columbia
Year: 2009

description: The purpose of the present study was to investigate the development of spelling in deaf and hard of hearing children. 16 deaf and hard of hearing children between the ages of 5 and 11 with a moderate-severe to profound hearing loss, who primarily communicated orally, formed the experimental group. 16 normal hearing children between the ages of 4 and 9 formed the control group. Both groups of children were asked to provide a spontaneous spelling sample as well as to label 20 pictures on a structured word list. In addition, they were asked to participate in 3 metalinguistic awareness tests (2 of which were phonological awareness tests). The metalinguistic measures were included in the study to examine the often reported relationship between spelling and metalinguistic awareness, in deaf and hard of hearing children. The major findings from the present study were that deaf and hard of hearing children make the same types of errors as are seen in the spelling of hearing children, but that their spelling follows a somewhat different developmental pattern. Most of the deaf and hard of hearing children were scored in a later spelling stage of the model, which is dominated by visual-orthographic errors, suggesting that the spelling development of the deaf and hard of hearing children may not fit a model of spelling development designed to describe the spelling development of hearing children (Roper, 1991). In regards to the metalinguistic abilities tested, hearing children outperformed deaf and hard of hearing children in the metalinguistic measures. In both groups there was evidence of a correlation between the 2 abilities.

This is the last carnivore of large dimensions still dispersed in the region, albeit seriously threatened with extinction (cf. Shalmon 2004). In the course of this study two stuffed specimens were observed in the collection of the Palmyra Archaeological Museum; according to the manager of the museum, Ali Tahr (pers. comm. 1994), they were captured in the vicinity between 1970 and 1975. The adult stuffed specimen in the Basamfasal collection was hunted in the area of Jabal Bishri, between Raqqa and Deir-ez-Zor (cf. Masseti 2001); it appeared not to be pure-blooded but more likely the result of a wolf-dog crossing. According to F. Al-Yassine (1994, pers. comm.), wolves were present but rare in the mountains of Shoëh and north of Ifreen, whereas Abu Mazen (1994, pers. comm.) claimed they were also present in the Alawit Mountains (Bab Janné). In April 1994, three live individuals were observed in the zoological garden at Douma, originating respectively from Jabal Deir ez-Zor, Mayadin and Abu Kamal. At that time, the species appeared to be still dispersed in eastern Syria.

description: A palynological study of the Nayband Formation (central eastern Iran) has been carried out in order to review and update its stratigraphic framework. In its type locality the formation crops out on the southern flank of Nayband Mountain, about 200 km south of Tabas. It consists of a thick, mixed siliciclastic-carbonate sequence subdivided into four members; in ascending order: the Gelkan Member (mainly shales and silstones), the Bidestan Member (marls, siltstones with minor sandstones and fossiliferous limestones), the Howz-e-Sheikh Member (sandstones and siltstones), and the Howz-e-Khan Member (sponge and coral dominated reefs alternating with marls and sandstones). Three palynological assemblages have been recognised; in ascending order: a) an assemblage characterised by the presence of Annulispora folliculosa and A. microannulata which allows the Gelkan Member and most of the Bidestan Member to be assigned an early Norian age; (b) an assemblage marked by the first occurrence of Polycingulatisporites mooniensis, which indicates the upper part of the Bidestan Member is mid-late Norian; c) an assemblage containing Classopollis chateaunovi in association with Retitriletes austroclavatidites, Gliscopollis meyeriana, Limbosporites lundbladii, Rugaletes awakinoensis and Callialasporites dampieri that allows the Howz-e-Sheikh Member to be assigned a Rhaetian age. The presence of some Eurasian and/or cosmopolitan forms in the Rhaetian microflora reflects the position of the Iranian plate on the southern margin of Eurasia.

description: We present a new assessment of the contribution of Blazars to the extragalactic background radiation across the e.m. spectrum. Our calculations rely on deep Blazar radio counts that we derived combining several multifrequency surveys. The integrated Blazar emission yields a broad-band non-thermal background that in some parts of the e.m. spectrum dominates the extragalactic brightness. Blazars are the main point-like contributors to the CMB. Their integrated emission causes an apparent T increase of 5-50 muK in the 50-250 GHz range. The CMB fluctuation spectrum is sensibly contaminated at l>300, for a Poissonian source distribution, or at lower l values if spatial clustering is present. We estimate that well over 100,000 Blazars will produce a significant signal in the PLANCK CMB anisotropy maps. Because of the microwave-Xray flux correlation, these sources are expected to have flux > a few 10^{-15} erg/s in the soft X-ray band. Thus, a large fraction of the foreground sources in CMB anisotropy maps could be identified and removed using a multi frequency approach, provided that a sufficiently deep all sky X-ray survey will be available. We further show that Blazars are a major constituent of all high-E extragalactic backgrounds. Their contribution is 11-12% at X-ray frequencies and possibly 100% in the 0.5-50 MeV band. At E>100 MeV, the Blazar collective emission, obtained extrapolating their integrated micro-wave flux to the gamma-ray band using the SED of EGRET detected sources, over-predicts the extragalactic background by a large factor, implying that Blazars not only dominate the gamma-ray sky but also that their average duty cycle at these frequencies must be rather low. We also find that Blazars of the HBL type may produce a significant amount of flux at TeV energies.

description: We present the second data release for the HI-MaNGA programme of HI follow-up observations for the SDSS-IV MaNGA survey. This release contains measurements for 3669 unique galaxies, combining 2108 Green Bank Telescope observations with an updated crossmatch of the MaNGA sample with the ALFALFA survey. We combine these data with MaNGA spectroscopic measurements to examine relationships between HI-to-stellar mass ratio (M_HI/M_*) and average ISM/star formation properties probed by optical emission lines. M_HI/M_* is very weakly correlated with the equivalent width of Halpha, implying a loose connection between the instantaneous star formation rate and the HI reservoir, although the link between M_HI/M_* and star formation strengthens when averaged even over only moderate timescales (~30 Myrs). Galaxies with elevated HI depletion times have enhanced [OI]/Halpha and depressed Halpha surface brightness, consistent with more HI residing in a diffuse and/or shock heated phase which is less capable of condensing into molecular clouds. Of all optical lines, M_HI/M_* correlates most strongly with oxygen equivalent width, EW(O), which is likely a result of the existing correlation between M_HI/M_* and gas-phase metallicity. Residuals in the M_HI/M_*-EW(O) relation are again correlated with [OI]/Halpha and Halpha surface brightness, suggesting they are also driven by variations in the fraction of diffuse and/or shock-heated gas. We recover the strong anti-correlation between M_HI/M_* and gas-phase metallicity seen in previous studies. We also find a relationship between M_HI/M_* and [OI]/Halpha, suggesting that higher fractions of diffuse and/or shock-heated gas are more prevalent in gas-rich galaxies.

description: We introduce a 3D compact U(1) lattice gauge theory having nonlocal interactions in the temporal direction, and study its phase structure. The model is relevant for the compact QED$_3$ and strongly correlated electron systems like the t-J model of cuprates. For a power-law decaying long-range interaction, which simulates the effect of gapless matter fields, a second-order phase transition takes place separating the confinement and deconfinement phases. For an exponentially decaying interaction simulating matter fields with gaps, the system exhibits no signals of a second-order transition.

description: A scanning SQUID microscope was used to image vortex trapping as a function of the magnetic induction during cooling in thin-film YBCO strips for strip widths W from 2 to 50 um. We found that vortices were excluded from the strips when the induction Ba was below a critical induction Bc. We present a simple model for the vortex exclusion process which takes into account the vortex - antivortex pair production energy as well as the vortex Meissner and self-energies. This model predicts that the real density n of trapped vortices is given by n=(Ba-BK)/Phi0 with BK = 1.65Phi0/W^2 and Phi0 = h/2e the superconducting flux quantum. This prediction is in good agreement with our experiments on YBCO, as well as with previous experiments on thin-film strips of niobium. We also report on the positions of the trapped vortices. We found that at low densities the vortices were trapped in a single row near the centers of the strips, with the relative intervortex spacing distribution width decreasing as the vortex density increased, a sign of longitudinal ordering. The critical induction for two rows forming in the 35 um wide strip was (2.89 + 1.91-0.93)Bc, consistent with a numerical prediction.
BIOSTRATIGRAPHY OF UPPER TRIASSIC-LOWER JURASSIC CARBONATE PLATFORM SEDIMENTS OF THE CENTRAL-SOUTHERN APENNINES (ITALY)

description: The results of a biostratigraphic study on the Upper Triassic-Lower Jurassic carbonate platform sediments are outlined. Three stratigraphic successions cropping out in different areas were analysed: Monte Cefalo, (Aurunci Mts, southern Latium), Costa dei Frascari (Matese, northern Campania) and Monte Meta (Gran Sasso d’Italia, Abruzzi). The study of microfossil assemblages composed of benthic foraminifers and calcareous algae allowed identification of four biozones and one subzone. From the bottom upwards, the biostratigraphic units are: the Triasina hantkeni and Griphoporella curvata Zone; the Thaumatoporella parvovesiculifera Zone; the Palaeodasycladus mediterraneus Zone; the Valvulinidae and Rivulariaceae Zone; and the Orbitopsella Subzone. Besides, the lower part of the Costa dei Frascari section was referred to the portion of the Norian below the first occurrence of the Triasina hantkeni and Griphoporella curvata. These sediments are characterized by a rich assemblages mostly composed of pseudoudoteaceans algae, echinoderm remains, chaetetids and large gastropods. Microbiostratigraphic study of the Upper Triassic-Lower Jurassic sediments highlighted a similar succession of bioevents in all the sections analysed allowing precise bio- and chronostratigraphic correlations to be made. In contrast, the paleoecological data obtained from biofacies analysis combined with lithological features observed in coeval units point to different depositional environments, reflecting time and space variation within the context of a single, large carbonate platform. In fact, both sedimentation, and the observed associations of organisms, were controlled by chemical-physical factors connected to variations in water energy and water circulation. Instead, in other cases tectonics and subsidence seem to have played an essential role.

 In the course of this research it was possible to examine one adult stuffed specimen in the collections of the Palmyra Archaeological Museum (PAM), another in the house of the taxidermist Mohammed Al Salie in the village of Salamieh (which had been captured in the vicinity), and another which was on sale in a shop at Damascus airport, very likely captured in the surroundings in 1992. The occurrence of the wild cat in the protected desert area of Al talila, Tadmor (= Palmyra) was confirmed in 2001 by the results of a camera trapping campaign carried out by Serra et al. (2007).

description: A maior parte das espécies que conhecemos atualmente são insetos. Com mais de 1 milhão de espécies descritas, o estudo da classificação e relações evolutivas dos insetos é praticamente a única maneira tangível de atingir uma compreensão razoável da grande diversidade biológica representada por este grupo. Os insetos são parte do filo Arthropoda, como mencionado no capítulo anterior; mais precisamente, do subfilo Hexapoda, que por sua vez é subdividido na classe Entognatha (um grupo provavelmente não monofilético constituído por 3 ordens) e na classe Ectognatha ou Insecta, que contém cerca de 28 a 31 ordens, dependendo da classificação utilizada (Figura 1).

description: The aim of this thesis was to investigate the culture of drinking in a rural community. The emphasis on culture in the title was to distinguish it from the type of research normally found in the alcohol field. So much of the literature in alcohol research has been dominated by a concern with alcohol problems. The research for this thesis was based on two years fieldwork in an East Anglian community and involved extensive participant observation both in the pubs in the village and in the homes of the residents. I examined the way in which drinking both publicly and privately was organised into particular social groups which were based on class, gender, community membership and age. The major findings of my research were as follows: First I discovered that the pubs in the village did not conform to the popular idea of pubs as public drinking places open to people from different social backgrounds. Instead they tended to reinforce the social divisions which already operated in the community. Second although I had set out to investigate the culture of drinking I found that each social group possessed its own distinctive culture of drinking which determined who drank where, when, with whom and in what way. Moreover none of these cultures were organised solely around drinking but instead were developed around ways of pursuing a particular type of social life. Third I was struck by the fact that in spite of a relatively high consumption of alcohol by some people, drinking was not seen as a social problem. Finally I attempted to make use of some anthropological ideas to show how group culture worked to control potentially problematic aspects of drinking. I hope that these efforts will be of benefit to researchers involved in the study of alcohol problems.
STRATIGRAPHY OF RHAETIAN TO LOWER SINEMURIAN CARBONATE PLATFORMS IN WESTERN LOMBARDY (SOUTHERN ALPS, ITALY): PALEOGEOGRAPHIC IMPLICATIONS

description: A stratigraphical revision of the Upper Triassic-Lower Jurassic succession of the western Southern Alps (Varese area) leads to the introduction of one new lithostratigraphical unit: the ?upper Hettangian-lower Sinemurian Alpe Perino Limestone and the recognition, also in the western Lombardy, of the Rhaetian Zu Limestone, consisting of subtidal cycles, with inner platform facies at the base (Campo dei Fiori Dolomite). These formations represent lagoonal-peritidal to subtidal carbonate depositional systems. A locally angular unconformity between the Rhaetian (or the lower Hettangian) and the upper Hettangian-Sinemurian formations, characterised by ‘terra rossa’ paleosols and pedogenetic carbonate breccias, can be correlated through all of the investigated profiles. The Lower Jurassic paleogeography of the western Lombardy Basin was characterised by an emerged area from Hettangian until earliest Sinemurian times in a warm humid paleoclimate. The Alpe Perino Limestone represents a small peritidal to subtidal carbonate platform developed only in a shallow-water gulf of the M. Nudo area. The platform was surrounded by a wide emerged area (island or peninsula ?), in the west to southeast, and by open subtidal and basinal environments, in the east to northeast (M. Generoso basin).

description: Background : Recently, Bijker et al. [Phys. Rev. Lett. 122, 162501 (2019)] explained the rotation-vibration spectrum of 13C by assuming triangular nuclear shape with D'3h symmetry. Purpose : The purpose of this work is to test the shape and symmetry of 13C based on a microscopic nuclear model without assumption of nuclear shape. Method : We have applied the real-time evolution method to 13C. By using the equation-of-motion of clusters, the model describes the 3alpha+n system without any assumption of symmetry. Results : REM described the low-lying states more accurately than the previous cluster model studies. The analysis of the wave functions showed that the ground band has approximate triangular symmetry, while the excited bands deviate from it. Conclusion : This work confirmed that the ground band has the intrinsic structure with the triangular arrangement of three alpha particles.
