description: The interdisciplinary study of two deep cores drilled in Pleistocene basin fill at Northern margin of Po Plain, has been integrated with qualitative and quantitative malacological analysis. The potential of quantitative malacological analysis, to refine results obtained from interdisciplinary studies, is here highlighted. The evolution of malacological assemblages has been recorded and correlated to the general regressive trend recognized all over the Po Basin. Lower Pleistocene marine deposits, found at core base (Jaramillo Subchron and older), were gradually replaced by transitional and continental deposits since latest early Pleistocene. Area was eventually covered by continental conglomerate deposits (“Ceppo” facies) during middle-late Pleistocene. Within this general trend, regional significance of a major unconformity (“r” surface), related to onset of Pleistocene glacial cycle, is confirmed. However, as evidenced by malacology, the roughly synchronous onset of coarse clastic progradation did not result in a synchronous shift from marine to transitional and continental settings all over the study area, as an effect of inherited topography and other local factors. During marine sedimentation, fossil record allowed us to recognize a transgressive event, reliably correlated to Marine Isotope Stage 35.

Stellar halos of Milky Way-type galaxies in Eagle high resolution simulations

Year: 2019

description: We study the stellar halos of Milky Way-type galaxies in the Eagle simulations and in a new set of zoomed Milky Way-mass galaxies resimulated at higher resolution. We analyse the surface brightness, metallicity, colour and age profiles of simulated halos - both across the major and minor axes - and find good agreement with observations. We find that the observed properties of stellar halos can be explained by a mixture of in situ and accreted components.We suggest that observations of stellar halos need to target also the major axes of galaxies (where most of the in situ halo stars reside), in order to get a complete picture of stellar halos of galaxies.

description: The Arene Candide Cave (Finale Ligure, Northern Italy) is considered one of the most important prehistoric site in Italy. The archaeological excavations conducted by the “Istituto Italiano di Paleontologia Umana” of Rome revealed 3 different horizons: an upper horizon with Holocene human presence dated from the Neolithic to the Byzantine period, and two underlying Pleistocene horizons with Gravettian and Epigravettian lithic artefacts. The stratigraphical sequence of the upper Palaeolithic is divided in two groups of strata separated by a depositional gap: the “P” complex, divided in 13 layers, dated from 25,620 to 18,560 years BP, and the 5 “M” layers dated between 11,750 and 9,980 years BP (14C non-calibrated dating).
In this paper the fossil bone remains of bats from “M” layers are described. Fifteen taxa, divided into 3 families and 6 genera have been identified: Rhinolophus ferrumequinum, R. mehelyi, R. euryale, R. hipposideros, Myotis myotis, M. blythii, M. capaccinii, M. emarginatus, M. mystacinus s.l., Myotis sp. (small sized), Plecotus auritus s.l., Nyctalus lasiopterus, N. noctula, Barbastella barbastellus and Miniopterus schreibersii. Comments for each of these taxa on current ecological and geographical distributions are presented, together with some osteometric measures and recent data referred to Late Pleistocene fossils bats in Italy. Finally, the value of this bat tanathocoenoses as a microclimatic, environmental, and human activity indicators is discussed.

description: Dynamical models of inflation are given with composite inflatons by means of massive supersymmetric gauge theory. Nearly flat directions and stable massive ones in the potential are identified and slow-roll during inflation is examined. This kind of dynamical inflations may be ubiquitous in fundamental unified theory with supersymmetry, which should contain gauge theories for interactions of elementary particles.

We introduces one basic concepts of the operator theory in Hilbert spaces, the order of the selfadjoint and positive operators and the orthogonal projections. The basic idea of the theorem is that a linear, bounded and selfadjoint operator can represent as a Riemanns Stieltjes integral. The present proof of the theorem is based in the decomposition of the operator into positive and negative part and is a detailed representation of the proof of the B.A. Lengyel-M.H. Stone and S.J.

description: It was shown in [hep-th/0503009], in the context of bosonic theory that the IR singular terms that arise as a result of integrating out high momentum modes in nonplanar diagrams of noncommutative gauge theory can be recovered from low lying tree-level closed string exchanges. This follows as a natural consequence of world-sheet open-closed string duality. Here using the same setup we study the phenomenon for noncommutative ${\cal N}=2$ gauge theory realised on a $D_3$ fractional brane localised at the fixed point of $C^2/Z_2$. The IR singularities from the massless closed string exchanges are exactly equal to those coming from one-loop gauge theory. This is as a result of cancellation of all contributions from the massive modes.

Boundary Green's Function for Spin-Incoherent Interacting Electrons in One Dimension

description: The spin-incoherent regime of one-dimensional electrons has recently been explored using the Bethe ansatz and a bosonized path integral approach, revealing that the spin incoherence dramatically influences the correlations of charge excitations. We here introduce a bosonization scheme for strongly interacting electrons, allowing us to generalize the description to account for the presence of an open boundary. By calculating the single-electron Green's function we find that the charge sector power-law scaling is highly sensitive to the boundary. Our result allows for a detailed description of the crossover between boundary and bulk regimes. We predict that scanning tunneling microscopy on a spin-incoherent system will pick up oscillations in the differential tunneling conductance as a function of the applied voltage $V$ at "intermediate" distances $x$ from a real or a dynamically generated boundary. The wavelength of the oscillations, $πv_c/x$, probes the speed $v_c$ of the charge excitations, and therefore the strength of the electron-electron interaction.

Kohlberg and ethical universalism
Creators: name: Yeung, Kwok Wing Anthony
Publisher: name: University of British Columbia
Year: 2009

description: This dissertation is a study of Kohlberg's moral psychology, which is a six-stage model of moral development. Kohlberg claims that his stages form a universal invariant sequence and that they are hierarchical, i.e., higher stages are better than lower stages. Accordingly, he claims that Stage 6 morality, which centers on justice, is universally valid. This ethic of justice is embodied mainly in respect for persons, fairness, and the procedural principle of ideal role taking. Kohlberg claims not only that Stage 6 values and principles are universally valid, but also that they are determinate. In other words, reasoning in terms of these values and principles guarantees that, for each particular moral problem, there will be a distinct solution on which all morally mature people could agree. By making these claims Kohlberg is advocating a strong and traditional version of universalism, which I call 'paradigm universalism.' The dissertation is divided into five chapters. In the first two chapters I outline Kohlberg's theory and explore its philosophical implications. In Chapter 3 I discuss Kohlberg's debates with two important critics, Gilligan and Flanagan. Gilligan claims that Kohlberg's emphasis on justice rather than care indicates a gender bias in his model. Flanagan, on the other hand, argues that since morality is multifarious it is wrong to equate morality either with justice or care of a combination of both. While these criticism do point out certain shortcomings of Kohlberg's theory, I argue that they do not seriously threaten the universal validity of Stage 6 moral values and principles in general. Chapter 4 introduces the main philosophical arguments of this dissertation. In this chapter I argue that (1) moral psychology is relevant to moral philosophy; (2) that the claim of hierarchy for the Kohlbergian stages does receive significant support from his research; and therefore (3) Stage 6 does plausibly reflect certain universal moral ideals. At the same time I allow (4) that there is clearly certain cultural bias in Kohlberg's theory and (5) that he is excessively optimistic about the determinacy of Stage 6 moral reasoning. In the final Chapter, I reflect on the universalism-relativism debate in light of Kohlberg's theory. I argue that paradigm universalism is too strong for Kohlberg to support, and that universalism is acceptable only in a weakened form which I call 'minimal universalism.' Contrary to the hope of paradigm universalists, this minimal universalism cannot serve as a comprehensive theory for solving moral problems. Neither does it exclude all forms of ethical relativism, but it does set important limits to any acceptable relativist theory.

description: An object withdrawn from a liquid bath is coated with a thin layer of liquid. Along with the liquid, impurities such as particles present in the bath can be transferred to the withdrawn substrate. Entrained particles locally modify the thickness of the film, hence altering the quality and properties of the coating. In this study, we show that it is possible to entrain the liquid alone and avoid contamination of the substrate, at sufficiently low withdrawal velocity in diluted suspensions. Using a model system consisting of a plate exiting a liquid bath, we observe that particles can remain trapped in the meniscus which exerts a resistive capillary force to the entrainment. We characterize different entrainment regimes as the withdrawal velocity increases: from a pure liquid film, to a liquid film containing clusters of particles, and eventually individual particles. This capillary filtration is an effective barrier against the contamination of substrates withdrawn from a polluted bath and finds application against biocontamination.

description: The Large Survey Project (LSP) "MeerKAT Absorption Line Survey" (MALS) is a blind HI 21-cm and OH 18-cm absorption line survey in the L- and UHF-bands, with the primary goal to better determine the occurrence of atomic and molecular gas in the circum-galactic and inter-galactic medium, and its redshift evolution. Here we present the first results using the UHF-band, obtained towards the strongly lensed radio source PKS1830, detecting absorption in the lens galaxy. With merely 90min of data acquired on-source for science verification and processed using the Automated Radio Telescope Imaging Pipeline (ARTIP), we detect in absorption the known HI 21-cm and OH 18-cm main lines at z=0.89 at an unprecedented signal-to-noise ratio (4000 in the continuum, with 6km/s channels). For the first time we report the detection at z=0.89 of OH satellite lines, so far not detected at z $>$ 0.25. We decompose the OH lines into a thermal and a stimulated contribution, where the 1612 and 1720MHz lines are conjugate. The total OH 1720MHz emission line luminosity is 6100Lsun. This is the most luminous known 1720MHz maser line. The absorption components of the different images of the background source sample different light paths in the lensing galaxy, and their weights in the total absorption spectrum are expected to vary in time, on daily and monthly time scales. We compare our normalized spectra with those obtained more than 20 yrs ago, and find no variation. We interpret the absorption spectra with the help of a lens galaxy model, derived from an N-body hydro-dynamical simulation, with a morphology similar to its optical HST image. It is possible to reproduce the observations without invoking any central gas outflows. There are, however, distinct and faint high-velocity features, most likely high-velocity clouds. These clouds may contribute to broaden the HI and OH spectra.

description: In this article, we discuss the identity and indistinguishability of quantum systems and the consequent need to introduce an extra postulate in Quantum Mechanics to correctly describe situations involving indistinguishable particles. This is, for electrons, the Pauli Exclusion Principle, or in general, the Symmetrization Postulate. Then, we introduce fermions and bosons and the distributions respectively describing their statistical behaviour in indistinguishable situations. Following that, we discuss the spin-statistics connection, as well as alternative statistics and experimental evidence for all these results, including the use of bunching and antibunching of particles emerging from a beam splitter as a signature for some bosonic or fermionic states.

description: In this document we performed a series of experiments concerning videoconferencing over a wireless environment in order to study the behavior of some of the most popular audio & video codec used today. In the first chapter we explain everything that someone may need in case he wants to reproduce those experiments. That is, we describe all the software and hardware components used in our experiments. Furthermore, a reference is made to the operational principles of our wireless network. In the second chapter, we have recorded all the values of our measurements. These metrics depend on the state of the wireless channel as well as the performance of the audio & video codec and are showed within the form of numerous matrixes. In the end of the chapter, we mention some issues and problems we faced during the building of this project. In the last and final chapter, we present our conclusions using the help of diagrams we built by plotting the values of the metrics from the previous chapter.

description: Distefania, one of the several ammonites genera described during the thirties in the upper Pliensbachian faunas from Taormina (Sicily), is involved by a case of homonymy. A recent study on the ammonoid assemblages of the late Pliensbachian-early Toarcian transition in the Apennines evidenced that it would be useful to keep a separate and valid name for this previously underrated Mediterranean genus, in order to better understand the time intervals and improve correlations. Moreover, it shows morphologic and sutural differences compared to the genera with which it is usually mistaken, and its vertical range is partially different as well. Therefore, in accordance with the ICZN rules, the form in question is here renamed as Distefaniceras.

description: A nearly complete but disarticulated skeleton of a small sized nothosaur is described. The specimen was collected in 2003 from an outcrop of the Besano Formation (Grenzbitumenzone of Swiss authors) of latest Anisian (Middle Triassic) age, in the Monte San Giorgio Area, northern Italy. The osteology of the postcranial skeleton supports the assignment to the genus Nothosaurus, and also excludes its belonging to Nothosaurus giganteus/Paranothosaurus amsleri already known from coeval localities of the Besano Formation in the Swiss part of the Monte San Giorgio area. Despite the lack of most of the skull, which contains diagnostic characters at the species level for Nothosaurus, the few preserved cranial elements suggest similarities with N. juvenilis which skull, and only known part, is also of comparable size. This specimen is particularly significant because it improves the knowledge of the osteology of N. juvenilis and because the second Nothosaurus species, smaller than N. giganteus/P. amsleri, suggests coexistence of sympatric species characterized by size and, probably, trophic differentiation within the genus Nothosaurus in the Monte San Giorgio area as occurred in the coeval Germanic Basin.

description: The research examines the reasons behind AI adoption for inventory management in Bahraini retail small and medium-sized enterprises (SMEs). This is because there have been radical transformations within the trade industry largely influenced by artificial intelligence incorporation into inventory control systems. Good control of stock has always been important to success in retail since many businesses grapple with it. Considering that nearly 30% of businesses here are SMEs, they are a critical component in Bahrain. This dissertation used qualitative methods through carrying out semi-structured interviews with top-ranking officials from various sectors who provided insights into inventory controls from their own experiences. The findings show that adoption of AI in inventory control is necessary for future planning although there are challenges which managers must confront with. Nevertheless, it was suggested that rather than entirely switching over, small and medium enterprises should adopt this technology gradually and train their staff more on its usage besides continually monitoring as well as upgrading such programs so as derive maximum benefits from them. Investigating into how artificial intelligence may impact on operational efficiency, customer satisfaction levels, profitability, and sustainable business practices during digital era among other things Highlighting the impact of Artificial Intelligence (AI) on Small Medium Enterprises (SMEs) in Bahrain this research looks also at ways through which these could be improved.

Unlike the well-known protocol for the epitaxy of ZnSe-based quantum structures on (001) GaAs, we find that the fabrication of quantum well structures on (110) GaAs requires significantly different growth conditions and sample architecture. We use magnetotransport measurements to confirm the formation of a two-dimensional electron gas in these samples, and then measure transverse electron spin relaxation times using time-resolved Faraday rotation. In contrast to expectations based upon known spin relaxation mechanisms, we find surprisingly little difference between the spin lifetimes in these (110)-oriented samples in comparison with (100)-oriented control samples.

description: A new taxon belonging to Neopterygians is described, based on very nicely preserved specimens from the rich vertebrate levels recently discovered in Luoping County, Yunnan Province, South China. This new assemblage dates to Pelsonian (Anisian, Middle Triassic), about the same age of the Panxian Fauna from the nearby Guizhou Province. The Luoping Fauna, yielding this new taxon, is turning out to be one of the most important fish faunas of the whole Middle Triassic and the oldest evidence of the fish radiation of this time span. This new genus of basal neopterygian shows unique derived characters, especially for the almost naked body, with a single row of urodermals covering the body lobe in the tail and a row of very small and thin scales bearing the lateral line canal along the flank. Also in the axial skeleton the new taxon shows peculiar characters such as the neural spines perfectly aligned to each paired neural arches and abdominal ribs well developed. Concerning skull bones, no suborbitals have been detected.

description: We have analysed the asymmetry of lines Fe I and Fe II in spectra of a solar flux using three FTS atlases and the HARPS atlas and also in spectra of 13 stars using observation data on the HARPS spectrograph. To reduce observation noise individual line bisectors of each star have been averaged. The obtained average bisectors in the stellar spectra are more or less similar to the shape C well known to the Sun. In stars with rotation speeds greater than 5 km/s the shape of the bisectors is more like /. The curvature and span of the bisectors increase with the temperature of the star. Our results confirm the known facts about strong influence of rotation velocity on the span and shape of bisectors. The average convective speed was determined based on the span of the average bisector, which shows the largest difference between the velocity of cold falling and hot rising convective flows of the matter. It's equal to -420 m/s for the Sun as a star. In solar-type stars, it grows from -150 to -700 m/s with an effective temperature of 4800 to 6200 K, respectively. For stars with greater surface gravity and greater metallicity, the average convective velocity decreases. It also decreases with star age and correlates with the speed of micro and macroturbulent movements. The results of solar flux analysis showed that absolute wavelength scales in the FTS atlases used coincide with an accuracy of about -10 m/s, except for the atlas of Hinkle, etc., whose scale is shifted and depends on the wavelength. In the range from 450 to 650 nm, the scale shift of this atlas varies from -100 to -330 m/s, respectively, and it equals on average of -240 m/s. The resulting average star bisectors contain information about the fields of convective velocities and may be useful for hydrodynamic modeling of stellar atmospheres in order to study the characteristic features of surface convection.

Subjects: Lagerstätte; Middle Triassic; Monte San Giorgio; Southern Alps; Plant fossils; Elatocladus

description: A newly opened excavation in the Cassina beds of the Lower Meride Limestone (Monte San Giorgio UNESCO WHL, Canton Ticino, Southern Alps) has yielded a small collection of Ladinian plant fossils, together with vertebrate (mostly fish) and invertebrate remains. The flora contains at least five species; conifer remains assignable to the genera Elatocladus, Voltzia and ?Pelourdea are the most common elements. A new species, Elatocladus cassinae n. sp., is formally described. Co-occurring with the conifers are seed ferns (Ptilozamites) and a few putative cycadalean remains (?Taeniopteris). Among the identified genera, only Voltzia has previously been reported from Monte San Giorgio. The fossils presented in this paper indicate that a diversified flora thrived in the region during the Ladinian. Floral composition and preservation patterns are suggestive of a taphonomically-biased record and a relatively far-away source area.

Stellar halos from deep VST surveys: comparing observations and theory
Creators: name: Spavone, Marilena
Publisher: name: Zenodo
Year: 2019

description: In the recent years, a big effort was made to develop deep photometric surveys aimed at studying galaxy structures down to the faintest levels of surface brightness of mu_g~27-30 mag/arcsec^2 .
 In this context, the VST Early-type GAlaxies Survey (VEGAS) is producing competitive results. Therefore, taking advantage of the deep photometry, we can address the build up history of the stellar halo by comparing the surface brightness profile and the stellar mass fraction with the prediction of cosmological galaxy formation. One of the priority science goals of VEGAS is to study the faint outer regions of the massive galaxies in groups and clusters. The deep observations can be directly compared with the predictions from the up-to-date theories for the stellar halo formation and the relation with the galaxy environment.
 In this talk, I will review the main results on the study of galaxy stellar halos of ETGs by using both VEGAS and FDS deep images.
REVISION OF THE EARLY CRETACEOUS CORAL GENUS FELIXIGYRA
Creators: name: LÖSER, HANNES
Publisher: name: Università degli Studi di Milano
Year: 2010
Subjects: Scleractinian corals; Systematics; Felixigyra; Cretaceous; Italy

description: The Early Cretaceous coral genus Felixigyra Prever, 1909 is revised on the basis of type material from Italy. Felixigyra has a hydnophoroid-meandroid colony organisation with conical monticules attached to each other. The very thick monticules are arranged in a way that calicular centres become apparent. The septa are compact and rhopaloid. The genus can be related to other genera of the Eugyridae family, but differs from them by its particularly developed monticules. It also shows certain resemblance to meandroid genera of the Trochoidomeandridae family. Of the six species originally assigned to Felixigyra only five are recognized, since the type of Felixigyra crassa is too poorly preserved to give a diagnosis. The remaining five species have almost no significant difference in calicular dimensions. In addition to the Italian material, one sample from the Early Cenomanian of Greece and one sample from the Early Albian of Mexico are also assigned to the genus. Material assigned to Felixigyra after Prever (1909) needs to be entirely reclassified to the genus Eohydnophora.

description: The organic walled dinoflagellate cyst Pseudorhombodinium cinguloindentatum gen. et sp. n. is formally described from the Upper Eocene of Sicily, Italy. It consists of a brown coloured, circumcavate wetzelielloid cyst with marked V-shaped cingular indentations in the pericyst. The proposed generic name refers to similarities existing in the overall morphology with the genus Rhombodinium Gocht. However, substantial differences in archeopyle styling, in the disposition of antapical horns, and in the amount of cingular indentation, advocate the erection of the new genus Pseudorhombodinium.

A numerical approach for radiative cooling in relativistic outflows

Subjects: subject: High Energy Astrophysical Phenomena (astro-ph.HE)

description: In high energy astrophysics scenarios such as blazars, GRBs or PWNe, it is highly probable that ultra-relativistic particles interact with photons in their environment through scattering. As long as the energy of the particle is greater than the energy of the interacting photon, the (classical) scattering is known to be in the Thomson regime. Otherwise, quantum effects will affect the scattering cross section, and we enter into the so-called Klein-Nishina regime. It is well known that radiative cooling in the Thomson regime is very efficient, leading to soft high-energy spectra. However, observations have shown that, in many cases, the high energy spectrum of some objects is rather hard. This has led to think that maybe particles are not being cooled down efficiently. Asymptotic approximations of the Klein-Nishina regime have been formulated in the last decades in order to account for these corrections in the distribution of particles responsible for the observed spectrum of high energy sources. In this work we presenta a numerical approach of the Klein-Nishina corrections to the radiative cooling. It has been developed to simulate the evolution of a distribution of particles interacting with photons in their surroundings via inverse Compton scattering.

description: The research examines the reasons behind AI adoption for inventory management in Bahraini retail small and medium-sized enterprises (SMEs). This is because there have been radical transformations within the trade industry largely influenced by artificial intelligence incorporation into inventory control systems. Good control of stock has always been important to success in retail since many businesses grapple with it. Considering that nearly 30% of businesses here are SMEs, they are a critical component in Bahrain. This dissertation used qualitative methods through carrying out semi-structured interviews with top-ranking officials from various sectors who provided insights into inventory controls from their own experiences. The findings show that adoption of AI in inventory control is necessary for future planning although there are challenges which managers must confront with. Nevertheless, it was suggested that rather than entirely switching over, small and medium enterprises should adopt this technology gradually and train their staff more on its usage besides continually monitoring as well as upgrading such programs so as derive maximum benefits from them. Investigating into how artificial intelligence may impact on operational efficiency, customer satisfaction levels, profitability, and sustainable business practices during digital era among other things Highlighting the impact of Artificial Intelligence (AI) on Small Medium Enterprises (SMEs) in Bahrain this research looks also at ways through which these could be improved.

description: As further progress in the accurate and efficient computation of coupled partial differential equations (PDEs) becomes increasingly difficult, it has become highly desired to develop new methods for such computation. In deviation from conventional approaches, this short communication paper explores a computational paradigm that couples numerical solutions of PDEs via machine-learning (ML) based methods, together with a preliminary study on the paradigm. Particularly, it solves PDEs in subdomains as in a conventional approach but develops and trains artificial neural networks (ANN) to couple the PDEs' solutions at their interfaces, leading to solutions to the PDEs in the whole domains. The concepts and algorithms for the ML coupling are discussed using coupled Poisson equations and coupled advection-diffusion equations. Preliminary numerical examples illustrate the feasibility and performance of the ML coupling. Although preliminary, the results of this exploratory study indicate that the ML paradigm is promising and deserves further research.

description: A nonlinear Schrödinger equation (NLSE) has been derived by employing reductive perturbation method for investigating the modulational instability of dust-ion-acoustic waves (DIAWs) in a four-component plasma having stationary negatively charged dust grains, inertial warm ions, and inertialess non-thermal electrons and positrons. It is observed that under consideration, the plasma system supports both modulationally stable and unstable domains, which are determined by the sign of the dispersive and nonlinear coefficients of NLSE, of the DIAWs. It is also found that the nonlinearity as well as the height and width of the first and second-order rogue waves increases with the non-thermality of electron and positron. The relevancy of our present investigation to the observations in space plasmas is pinpointed.
