CERVIDEA AND MOSCHIDAE (MAMMALIA, ARTIODACTYLA) FROM THE BACCINELLO V-3 ASSEMBLAGE (LATE MIOCENE, LATE TUROLIAN, GROSSETO, ITALY)
Creators: name: ABBAZZI, LAURA
Publisher: name: Università degli Studi di Milano
Year: 2001

description: Cervids and a moschid coming from various sites in the Baccinello-Cinigiano basin (Grosseto, Tuscany, Central Italy) are described. These remains have been recovered from levels correlatable with the horizon where the faunal assemblage known as V3 has been found. In the sedimentary succession within the Baccinello-Cinigiano basin, five successive faunal associations have been recognised. These assemblages document phases of population spanning the Late Miocene-Early Pliocene. The oldest assemblage, termed V0, is correlated with the MN11 "zone" (early Turolian), V1 and V2 assemblages with the MN12 "zone" (late Turolian), and V3 with the MN13 "zone" (late Turolian). Sediments bearing V3 assemblage are unconformably overlain by Lower Pliocene deposits containing remains of mammals referred to the early Villafranchian MN16a "zone". The cervid material studied here is referred to three taxa, Paracervulus cf. australis, Procapreolus cf. loczyi, Cervidae indet., and to a new representative of the family Moschidae Tuscomeryx huerzeleri (nov. gen., nov. sp.). Because of the occurrence of genus Paracervulus, the assemblage can be referred to a phase transitional between the Turolian and Ruscinian Mammal Ages of the biochronological continental scale.

description: White dwarfs that accrete the debris of tidally disrupted asteroids provide the opportunity to measure the bulk composition of the building blocks, or fragments, of exoplanets. This technique has established a diversity in compositions comparable to what is observed in the solar system, suggesting that the formation of rocky planets is a generic process. Whereas the relative abundances of lithophile and siderophile elements within the planetary debris can be used to investigate whether exoplanets undergo differentiation, the composition studies carried out so far lack unambiguous tracers of planetary crusts. Here we report the detection of lithium in the atmospheres of four cool (<5,000 K) and old (cooling ages 5-10 Gyr) metal-polluted white dwarfs, where one also displays photospheric potassium. The relative abundances of these two elements with respect to sodium and calcium strongly suggest that all four white dwarfs have accreted fragments of planetary crusts. We detect an infrared excess in one of the systems, indicating that accretion from a circumstellar debris disk is on-going. The main-sequence progenitor mass of this star was $4.8\pm0.2 M_\odot$, demonstrating that rocky, differentiated planets may form around short-lived B-type stars.

Στην έρευνα πήραν μέρος 285 ναυαγοσώστες (210 άνδρες, 75 γυναίκες). Για την αξιολόγηση χρησιμοποιήθηκε ένα σύνθετο εργαλείο που αποτελούνταν από τις κλίμακες α)Abridged Job Descriptive Index για την ικανοποίηση από την ίδια την εργασία, το μισθό, τις δυνατότητες εξέλιξης, την επίβλεψη από τον προϊστάμενο και τους συνεργάτες, β)Job In General για την ικανοποίηση από την εργασία γενικά και μια κλίμακα για την πρόβλεψη της αποχώρησης από της εργασία. Το εργαλείο περιλάμβανε ερωτήσεις σχετικά με τα δημογραφικά και επαγγελματικά χαρακτηριστικά των ναυαγοσωστών. Από τα αποτελέσματα προέκυψαν ότι οι γυναίκες δείχνουνε περισσότερο ικανοποιημένες από τους άνδρες όσον αφορά στην συμπεριφορά των προϊσταμένων. Επιπλέον, οι ηλικίες 18-25 φάνηκαν περισσότερο ικανοποιημένοι από τον μισθό και τις δυνατότητες εξέλιξης από τις άλλες ηλικιακές ομάδες. Τέλος, η έρευνα έδειξε πως οι ναυαγοσώστες επηρεάζονται στην πρόθεσή τους για αποχώρηση από την εργασία τους από το περιεχόμενο της εργασίας από τους προϊσταμένους τους και γενικά από την εργασία. Συμπερασματικά, οι Έλληνες ναυαγοσώστες που συμμετείχαν στην έρευνα, φάνηκαν να είναι αρκετά ικανοποιημένοι από το επάγγελμα τους, το οποίο η συντριπτική πλειοψηφία αυτών, το ασκούν εποχιακά σαν μια ευχάριστη καλοκαιρινή ενασχόληση η οποία απολαμβάνει χρηματικές απολαβές.
description: The purpose of the current study was to investigate the job satisfaction of Greek lifeguards and to show the profile of the job. Participants, were 285 lifeguards (210 men, 75 women). For this purpose, an instrument was designed, which comprise by the following scales a)Abridged Job Descriptive Index for job satisfaction by work itself, promotion opportunities, supervision and people at work , b)Job In General for the job in general c)a scale for the intention to quit. Additionally, the instrument provided demographic and professional data. The results revealed that the women seemed to be more satisfied from the men from the attitude of the supervisors. Furthermore, the ages between 18-25years seems to be more satisfied from the salary and the promotion opportunities than the other age categories. Finally, the research revealed that lifeguards get influenced to the intention to quit from the factors "work itself" and the "supervisors" and "gob in general". Conclusively, Greek lifeguards who participate to the research, seemed to be well satisfied form their job, which the most of them do only on summer as a pleasant summer work-activity which gets paid.

description: The seasonal variation of bioavailable phosphorus, BioP, was determined in vineyards in two farming systems, organic (OR) and conventional (CR). BioP was calculated as the sum of the inorganic Pi, organic Po and microbial Pm phosphorus after incubation. In the organic system (OR), the BioP varied between 30 and 40 mg/Kg εδ. while in the conventional system (CR), it fluctuated between 80 and 120 mg/Kg soil. In the (OR), the participation of Pm and Po in the BioP was almost 50%, while in the (CR), the participation of Pm was 40% in the winter and spring period and for Po was 30% for the summer and winter. In the (OR), the mineralization of P ranged between 10 and 25 mg/Kg soil, while in the (CR) it varied between 10 and 50 mg/Kg soil with observed minimum rate for the (OR), during winter while for the CR in the autumn.

description: Accretion onto the supermassive black hole in some active galactic nuclei (AGN) drives relativistic jets of plasma, which dissipate a significant fraction of their kinetic energy into gamma-ray radiation. The location of energy dissipation in powerful extragalactic jets is currently unknown, with implications for particle acceleration, jet formation, jet collimation, and energy dissipation. Previous studies have been unable to constrain the location between possibilities ranging from the sub-parsec-scale broad-line region to the parsec-scale molecular torus, and beyond. Here we show using a simple diagnostic that the more distant molecular torus is the dominant location for powerful jets. This diagnostic, called the seed factor, is dependent only on observable quantities, and is unique to the seed photon population at the location of gamma-ray emission. Using $62$ multiwavelength, quasi-simultaneous spectral energy distributions of gamma-ray quasars, we find a seed factor distribution which peaks at a value corresponding to the molecular torus, demonstrating that energy dissipation occurs $\sim 1$ parsec from the black hole (or $\sim 10^{4}$ Schwarzchild radii for a $10^{9}M_{\odot}$ black hole).

Artificial broadening of the high-energy end of electron spectrum in supernova remnants
Creators: name: Petruk, O.
Publisher: name: arXiv
Year: 2006
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: The observed spectrum of a supernova remnant (SNR) is a superposition of many ``local'' spectra emitted by regions of SNRs that are under different physical conditions. The question remains as to whether the broadening of the high-energy end of the observed nonthermal spectrum of SNRs, like in G347.3-0.5 and SN 1006, can be an artifact of observations or it is a consequence of the microphysics involved in the acceleration process. In this note we study the influence of parameters variations (inside the volume and over the surface of SNR) on the shape of the high-energy end of the synchrotron (and also inverse Compton) spectrum. We consider three possibilities for these parameter variations: i) gradients downstream of the shock with constant maximum energy of the accelerated electrons and the potential variation in time of the injection efficiency, ii) then we add the possibility of the maximum energy depending on time, and finally iii) the possible obliquity dependences of maximum energy and injection efficiency. It is shown that gradients of density and magnetic field strength downstream of the shock are ineffective in modifying the shape of the synchrotron spectrum, even if an SNR evolves in the nonuniform interstellar medium and/or the injection efficiency varies in time. The time dependence of the maximum energy of the electrons accelerated by the shock is also not able to make the observed spectrum much broader. The only possibility of producing considerable broadening in the spectrum is the variation in the maximum energy of electrons over the surface of SNR. In such a case, the obliquity dependence of the injection efficiency also affects the shape of the spectrum, but its role is less significant.

GU Boo: A New 0.6 Msun Detached Eclipsing Binary

Publisher: name: arXiv
Year: 2005
Subjects: subject: Astrophysics (astro-ph)

description: We have found a new low-mass, double-lined, detached eclipsing binary, GU Boo, among a sample of new variables from the ROTSE-I database. The binary has an orbital period of 0.488728 +/- 0.000002 days, and estimated apparent magnitudes Vrotse = 13.7 and I = 11.8. Our analysis of the light and radial velocity curves of the system yields individual masses and radii of M1= 0.610 +/- 0.007 Msun, M2 = 0.599 +/- 0.006 Msun, R1= 0.623 +/- 0.016 Rsun, R2= 0.620 +/- 0.020 Rsun. The stars in GU Boo are therefore very similar to the components of the eclipsing binary YY Gem. For this study we have adopted a mean effective temperature for the binary of Teff = 3870 +/- 130 K. Based on its space velocities we suggest that GU Boo is a main sequence binary, possibly with an age of several Gyr. The metallicity of the binary is not well constrained at this point but we speculate that it should not be very different from solar. We have compared the physical parameters of GU Boo with current low-mass stellar models, where we accounted for uncertainties in age and metallicity by considering a wide range of values for those parameters. Our comparisons reveal that all the models underestimate the radii of the components of GU Boo by at least 10-15%. This result is in agreement with the recent studies of YY Gem and CU Cnc.

description: The palaeontologic site at Lavini di Marco, near to Rovereto (Trento), reveals a wide fossil tidal flat of Early Jurassic age (Calcari Grigi Formations – lower Member; Hettangian to lower Sinemurian ). An extensive set of dinosaur prints were discovered a few years ago and are now the subject of ichnological and paleobiological studies. The prints which are described in present short note are believed to represent the right and left foot of the same individual, set in a side-by-side, sub-parallel, sitting posture. The prints can be classified as Anomoepus Hitchcock 1848. Amongst recognised ichnospecies, most of the charachteristics of the prints here described point to Moyenisauropus dodai Ellenberger 1974 (recte Anomoepus dodai Olsen & Galton 1984) of Lesotho. By contrast, the prints found at Lavini di Marco differ from the Anomoepus found in central-east Europe. These characters would seem to confirm the Gondwanic origins of the Rovereto ichnofauna as previously supposed from the study of other taxa.

description: Spin-torque ferromagnetic resonance (ST-FMR) particularly using magnetic insulators and heavy metals possessing a giant spin Hall effect (SHE) has gotten a lot of attention for the development of spintronic devices. To devise complex functional devices, it is necessary to construct the equivalent spin-circuit representations of different phenomena. Such representation is useful to translate physical equations into circuit elements, benchmarking experiments, and then proposing creative and efficient designs. We utilize the superposition principle in circuit theory to separate the spin Hall magnetoresistance and spin pumping contributions in the ST-FMR experiments. We show that the proposed spin-circuit representation reproduces the standard results in literature. We further consider multilayers like a spin-valve structure with an SHE layer sandwiched by two magnetic layers and show how the corresponding spin-circuit representation can be constructed by simply writing a vector netlist and solved using circuit theory.

description: We consider a holographic model of QCD at finite temperature with nonzero chemical potentials conjugate to $R$-charge densities. A critical surface of the confinement-deconfinement phase transition is shown for five-dimensional charged black hole solution given by Behrnd, Cvetič and Sabra. On a special section of the parameter space, we find an critical curve being similar to the one expected in QCD. We calculate meson spectra and decay constants in the confinement phase of this section to see their temperature and chemical potential dependences. We could assure generalized GellMann-Oakes-Renner relation and the reduction of pion velocity near the critical point.

description: In this Letter, we propose and experimentally demonstrate a simple method to provide additional in-formation by conductivity measurements of soils. The AC electrical conductance of the soil is measured while it is exposed to a periodic vibration. The vibration-induced density fluctuation implies a corresponding conductivity fluctuation that can be seen as combination frequency components, the sum and the difference of the mean AC frequency and the double of vibration frequency, in the current response. The method is demonstrated by measurements on clayey and sandy soils.

description: As a consequence of the approximate spin-valley symmetry in graphene, the ground state of electrons in graphene at charge neutrality is a particular SU(4) quantum-Hall ferromagnet to minimize their exchange energy. If only the Coulomb interaction is taken into account, this ferromagnet can appeal either to the spin degree of freedom or equivalently to the valley pseudo-spin degree of freedom. This freedom in choice is then limited by subleading energy scales that explicitly break the SU(4) symmetry, the simplest of which is given by the Zeeman effect that orients the spin in the direction of the magnetic field. In addition, there are also valley symmetry breaking terms that can arise from short-range interactions or electron-phonon couplings. Here, we build upon the phase diagram, which has been obtained by Kharitonov [Phys. Rev. B \textbf{85}, 155439 (2012)], in order to identify the different skyrmions that are compatible with these types of quantum-Hall ferromagnets. Similarly to the ferromagnets, the skyrmions at charge neutrality are described by the $\text{Gr}(2,4)$ Grassmannian at the center, which allows us to construct the skyrmion spinors. The different skyrmion types are then obtained by minimizing their energy within a variational approach, with respect to the remaining free parameters that are not fixed by the requirement that the skyrmion at large distances from their center must be compatible with the ferromagnetic background. We show that the different skyrmion types have a clear signature in the local, sublattice-resolved, spin magnetization, which is in principle accessible in scanning-tunneling microscopy and spectroscopy.

Το ζήτημα αυτό είναι σίγουρο ότι θα συνεχίσει να απασχολεί τόσο τα νομοθετικά όργανα της Κοινότητας όσο και την ευρωπαϊκή κοινή γνώμη

description: In the early universe, the potential of a scalar field can be significantly modified, and the scalar field may be trapped for a long time in a different location than the current vacuum. The trapping effect can increase or decrease the scalar abundance. For instance, in thermal inflation, a scalar field is trapped at the top of the potential by a thermal effect and dominates the universe to drive inflation for a short period of time. On the other hand, a scalar abundance can be exponentially suppressed in the adiabatic suppression mechanism, where a scalar field moves adiabatically by a time-dependent trapping potential. In this study, we investigate such a trapping effect on the abundance of scalar fields. Specifically, we investigate how the abundance of a scalar field depends on its initial position in the case of a double well potential and identify the physical quantity that controls the abundance. Then, we study the QCD axion abundance for various values of the misalignment angle, where the axon potential receives a large temporal mass due to the Witten effect. We find that the axion abundance is suppressed due to the adiabatic suppression mechanism even when it is trapped near the maximum of the potential, if the trapping effect is sufficiently large.

description: We extend the analysis of asymmetric Dark Matter relic density with Sommerfeld enhancement to the case where the mediator is massive. In asymmetric Dark Matter models, the asymmetric Dark Matter is assumed to couple to light scalar or vector boson. Asymmetric Dark Matter annihilation cross section is enhanced by the Sommerfeld effect which exists due to the distortion of wavefunction of asymmetric Dark Matter particle and anti--particle by long--range interactions. The impacts of Sommerfeld enhancement on the relic densities of asymmetric Dark Matter particle and anti--particle are discussed. The effect of kinetic decoupling on the relic density is also probed when the annihilation cross section is enhanced by Sommerfeld enhancement. Finally, the constraints on the parameter space is given by using the observational data of Dark Matter.

description: We alleviate the circularity problem, whereby gamma-ray bursts are not perfect distance indicators, by means of a new model-independent technique based on Bézier polynomials. To do so, we use the well consolidate \textit{Amati} and \textit{Combo} correlations. We consider improved calibrated catalogs of mock data from differential Hubble rate points. To get our mock data, we use those machine learning scenarios that well adapt to gamma ray bursts, discussing in detail how we handle small amounts of data from our machine learning techniques. In particular, we explore only three machine learning treatments, i.e. \emph{linear regression}, \emph{neural network} and \emph{random forest}, emphasizing quantitative statistical motivations behind these choices. Our calibration strategy consists in taking Hubble's data, creating the mock compilation using machine learning and calibrating the aforementioned correlations through Bézier polynomials with a standard chi-square analysis first and then by means of a hierarchical Bayesian regression procedure. The corresponding catalogs, built up from the two correlations, have been used to constrain dark energy scenarios. We thus employ Markov Chain Monte Carlo numerical analyses based on the most recent Pantheon supernova data, baryonic acoustic oscillations and our gamma ray burst data. We test the standard $Λ$CDM model and the Chevallier-Polarski-Linder parametrization. We discuss the recent $H_0$ tension in view of our results. Moreover, we highlight a further severe tension over $Ω_m$ and we conclude that a slight evolving dark energy model is possible.

description: Identifying an efficient pathway to change the order parameter via a subtle excitation of the coupled high-frequency mode is the ultimate goal of the field of ultrafast phase transitions. This is an especially interesting research direction in magnetism, where the coupling between spin and lattice excitations is required for magnetization reversal. Despite several attempts however, the switching between magnetic states via resonant pumping of phonon modes has not yet been demonstrated. Here we show how an ultrafast resonant excitation of the longitudinal optical phonon modes in magnetic garnet films switches magnetization into a peculiar quadrupolar magnetic domain pattern, unambiguously revealing the magneto-elastic mechanism of the switching. In contrast, the excitation of strongly absorbing transverse phonon modes results in thermal demagnetization effect only.

DESCRIPTION OF AN EARLY ONTOGENETIC EVOLUTIONARY STEP IN LEPIDORBITOIDES (LEPIDORBITOIDES) BISAMBERGENSIS ASYMMETRICA, EARLY MAASTRICHTIAN (CENTRAL TURKEY)
Creators: name: ÖZCAN, ERCAN

description: Lepidorbitoides bisambergensis is characterised by having a ‘quadriserial’ embryo without any chamberlet directly arising from the deuteroconch and is a very diagnostic and common species in Lower Maastrichtian flysch successions in Anatolia. Some populations of this species present an early ontogenetic morphologic feature which is characterised by distinctly asymmetric early chamber arrangement recognised in the horizontal sections. This asymmetry is mainly caused by the pronounced difference in the size of auxiliary chamberlets which rest on both, protoconch and deuteroconch and also enhanced by the development of unequal number of chamberlets in the series arising from these auxiliary chamberlets on the protoconchal side. These asymmetric specimens are commonly identified in stratigraphic horizons below the symmetric ones after the introduction of a new auxiliary chamberlet and progressively replaced by symmetric ones in the younger populations. Asymmetric "quadriserial" specimens representing the early phylogenetic stage of L. bisambergensis described in the stratigraphic horizons corresponding to G. havanensis and G. aegyptiaca (?) zones are thought to deserve a particular taxonomic status and are attributed to Lepidorbitoides bisambergensis asymmetrica Özcan & Özkan-Altiner, 1999a.

description: Deep neural networks power most recent successes of artificial intelligence, spanning from self-driving cars to computer aided diagnosis in radiology and pathology. The high-stake data intensive process of surgery could highly benefit from such computational methods. However, surgeons and computer scientists should partner to develop and assess deep learning applications of value to patients and healthcare systems. This chapter and the accompanying hands-on material were designed for surgeons willing to understand the intuitions behind neural networks, become familiar with deep learning concepts and tasks, grasp what implementing a deep learning model in surgery means, and finally appreciate the specific challenges and limitations of deep neural networks in surgery.

description: The objective of the study was the determination of the moisture of extinction andthe probability of ignition of the annual herbaceous species Avena barbata Pott.exLink.Multiple ignition tests were conducted in situ from June 2006 until November2006. Meteorological data were recorded during the ignition tests using a weather beltkit and the fuel moisture content was determined by the oven-drying method. Theresults were analyzed using stepwise logistic regression to define the probability ofignition based on moisture content values and meteorological parameters. Stepwiselogistic regression indicated that only the fuel moisture content was statisticallysignificant (p<0.001), and consequently, it was the variable that was kept in theanalysis.The logistic model correctly predicted fire ignition in 97.2% of the tests. Moistureof extinction was determined at 52.5% o.d.w. for 50% ignition probability, while for1% ignition probability, moisture of extinction was estimated at 71,3%.Key words: ignition potential, moisture of extinction, stepwise logistic regression,Avena barbata Pott. ex Link.

description: Limestones of the latest Carboniferous-early Permian Rattendorf Group (Lower Pseudoschwagerina Limestone, Grenzland Formation and Upper Pseudoschwagerina Limestone) of the Carnic Alps (Austria/Italy) contain a rich and interesting assemblage of smaller foraminifers, algae and pseudo-algae. The foraminiferal assemblage of the Lower Pseudoschwagerina Limestone is identical to that of the Auernig Formation. The Grenzland Formation is characterized by the appearance of the genus Geinitzinaand Pseudovermiporella, and the disappearance of Bradyinidae. The Upper Pseudoschwagerina Limestone contains the same species as the Grenzland Formation, but is characterized by the local appearance of Neoendothyra (?) and diverse species of Hemigordiidae and Nodosarioidea. The biostratigraphical value of diverse species of Hemigordius, ìArenovidalinaîsensu Baryshnikov = ìNeohemigordiusîsensu Pinard & Mamet, Nodosinelloides, Protonodosariaand Geinitzinafor the Asselian and early Sakmarian stages is briefly discussed. The systematical part contains some generic remarks on the Hemigordiidae and Nodosarioidea. Due to the porcelaneous wall, the microfossils Ellesmerellapermica(Pia) (= ìGirvanellaî subparallelaFlügel & Flügel-Kahler) and Pseudovermiporella spp., which are generally interpreted as algae, are considered as attached miliolinid foraminifera. A new genus of problematical Chlorophyta, Homannisiphon,is established.
