description: Physics-guided deep learning (PG-DL) via algorithm unrolling has received significant interest for improved image reconstruction, including MRI applications. These methods unroll an iterative optimization algorithm into a series of regularizer and data consistency units. The unrolled networks are typically trained end-to-end using a supervised approach. Current supervised PG-DL approaches use all of the available sub-sampled measurements in their data consistency units. Thus, the network learns to fit the rest of the measurements. In this study, we propose to improve the performance and robustness of supervised training by utilizing randomness by retrospectively selecting only a subset of all the available measurements for data consistency units. The process is repeated multiple times using different random masks during training for further enhancement. Results on knee MRI show that the proposed multi-mask supervised PG-DL enhances reconstruction performance compared to conventional supervised PG-DL approaches.

description: We report the detection of a superorbital period in the high-mass X-ray binary 2S 0114+650. Analyses of data from the Rossi X-ray Timing Explorer (RXTE) All-Sky Monitor (ASM) from 1996 January 5 to 2004 August 25 reveal a superorbital period of 30.7 +/- 0.1 d, in addition to confirming the previously reported neutron star spin period of 2.7 h and the binary orbital period of 11.6 d. It is unclear if the superorbital period can be ascribed to the precession of a warped accretion disc in the system.

description: The coupling of electronic degrees of freedom in materials to create hybridized functionalities is a holy grail of modern condensed matter physics that may produce novel mechanisms of control. Correlated electron systems often exhibit coupled degrees of freedom with a high degree of tunability which sometimes lead to hybridized functionalities based on external stimuli. However, the mechanisms of tunability and the sensitivity to external stimuli are determined by intrinsic material properties which are not always controllable. A Mott metal-insulator transition, which is technologically attractive due to the large changes in resistance, can be tuned by doping, strain, electric fields, and orbital occupancy but cannot be, in and of itself, controlled externally with light. Here we present a new approach to produce hybridized functionalities using a properly engineered photoconductor/strongly-correlated hybrid heterostructure, showing control of the Metal-to-Insulator transition (MIT) using optical means. This approach combines a photoconductor, which does not exhibit an MIT, with a strongly correlated oxide, which is not photoconducting. Due to the close proximity between the two materials, the heterostructure exhibits large volatile and nonvolatile, photoinduced resistivity changes and substantial photoinduced shifts in the MIT transition temperatures. This approach can potentially be extended to other judiciously chosen combinations of strongly correlated materials with systems which exhibit optically, electrically or magnetically controllable behavior.

description: Internet is a key factor for the Society of Information as well for the growth of Ε-commerce. A substantial category of E-commerce is E-banking that includes, among others, I-banking (internet banking). There are many bank services offered through internet. The law adopts a quite narrow perception of consumer, who therefore has a limited protection regarding I-banking transactions. The most important stage of I-banking is the pre-contract one that includes negotiations and it is regulated thoroughly. The "general banking contract" theory can't be applied to I-banking. Banks are subject to both general and special obligations towards the client. Rescission from contract by client. Conclusion of contract is regulated mainly by the provisions of the Civil Code. There are issues regarding the electronic declaration of will and the form of the electronic contract. Issues regarding international private law. The issue of I-banking supervision.

description: The idea that mergers are more likely in dense groups or clusters coupled with the assumption that such events lead to cold gas flows onto black holes, suggests a direct relationship between the radiative efficiency of an active galactic nucleus and environmental richness. Observations, however, increasingly challenge this and other basic expectations. Mounting evidence, for example, shows an inverse trend between near-Eddington accreting objects and environmental richness. Broken down by radio galaxy subgroup, recent work has explored connections between low excitation radio galaxies with Fanaroff-Riley II jet morphology (FRII LERGs) and other radio galaxies. We make contact with that work by adding a discussion of the recently discovered FR0 radio galaxies and show how to fit them in a picture in which FRII LERGs are not initial nor final phases in the lifetime of a radio galaxy, but de facto transition states. We describe how to understand the observed X-ray luminosity/cluster richness relation as a fundamental correlation on the nature of the jet-disk connection.

In the framework of cluster formation and decay mechanism for particle production, the universal transverse energy distributions for pion and proton can be described separately but not simultaneously.

description: The present paper presents descriptions of 10 bryozoan species from material deposited at the Geological Centrum Göttingen, Germany. The studied material comes from the Lower Devonian rocks (Konĕprusy Limestone, Pragian), exposed in a quarry near Zlatý Kůň in Central Bohemia. Described bryozoans comprise 8 trepostome and 2 cryptostome (rhabdomesine) species. One genus and species is new: the cryptostome (rhabdomesine) Paracuneatopora striata gen. n., n. sp., and 7 species are new: trepostomes Leioclema elegans n. sp., Atactotoechus divulgatus n. sp., Loxophragma fistulosum n. sp., Leptotrypella punctata n. sp., Microcampylus obscurus n. sp., Dyscritella bohemica n. sp., and the rhabdomesine Orthopora tenuis n. sp. Furthermore, two trepostomes Monotrypa bohemica Prantl, 1933 and Anomalotoechus cf. typicus Duncan, 1939 were identified in this material. The described fauna displays palaeozoogeographic relations to the Lower Devonian (Pragian) of Morocco and the Middle Devonian of Michigan (USA).

Ο Θεός λατρευόταν με διάφορες υποστάσεις δημόσια, σε ιερά που εκτός από το Δίον δεν είχαν μνημειακό χαρακτήρα, αλλά και ιδιωτικά, σε βωμούς προς τιμήν του που υπήρχαν στις αυλές των οικιών. Συνολικά εξετάστηκαν τριάντα έξι θέσεις, στις δεκατέσσερεις από τις οποίες μπορεί να επιβεβαιωθεί η ύπαρξη ιερού, ενώ οι υπόλοιπες αποτελούν ενδείξεις για τη λατρεία του.
description: The cult of Zeus in Macedonia was fundamental as it proved not only by the ancient literature but also by the archeological relics. The god, under different substances, was worshipped in public, in temples that were not monumental apart from Dion, and privately as well, in altars dedicated to his honour in the house yards. In all, thirty-six positions were examined: in fourteen the existence of a sanctuary can be confirmed whereas the other ones constitute indications for his cult.

description: Superconducting flux qubits with three Josephson junctions are promising candidates for the building blocks of a quantum computer. We have applied the imaginary time evolution method to study the model of this qubit accurately by calculating its wave functions and eigenenergies. Because such qubits are manipulated with magnetic flux microwave pulses they might be irradiated into non-computational states which is called the leakage effect. Through the evolution of the density matrix of the qubit under either hard-shaped pulse or Gaussian-shaped pulse to carry out quantum NOT operation, we show that the leakage effect is not a serious problem for a flux qubit.

description: Due to the presence of extra top quark T in the little Higgs models, the $CKM$ matrix is not unitary and the flavor changing neutral currents may exist at the tree level. In the context of the Littlest Higgs(LH) model, we discuss the top-charm production at the high-energy linear $e^{+}e^{-}$ collider $(LC)$ via the processes $e^{+}e^{-}\to \bar{t}c +t\bar{c}$, $e^{+}e^{-}\to (\bar{t}c +t\bar{c})ν_{e}\bar{ν_{e}}$, and $e^{-}γ\to e^{-}\bar{t}c$. We find that the resonance production cross section for the process $e^{+}e^{-}\to \bar{t}c+ t\bar{c} $ is significantly larger, which can be detected in future $LC$ experiments.

Presenting unity, performing diversity: Sto:lo identity negotiations in venues of cultural representation
Creators: name: Hiwasaki, Lisa
Publisher: name: University of British Columbia
Year: 2009

description: In the process of negotiating land claims, First Nations in British Columbia and Canada face the challenging task of presenting a unified identity without trampling on the inevitable diversity within their communities. This thesis explores the perceived conflict between unity and diversity amongst Native populations. It brings together fieldwork in Stó:lō territory in the Fraser Valley of British Columbia, performance theory, and contemporary discourse surrounding identity production at this particular point in time. The work examines performance of identity as a form of social action and the variability of identity performances. Data was gathered from interviews with people involved with two sites where educational programmes are being developed for local students: Xa:ytem Longhouse Interpretive Centre at Hatzic Rock, near Mission, and Longhouse Extension Programme/ Shxwt'a:selhawtxw on St6:l o Nation grounds in Chilliwack. The theme explored in this thesis is that just as unity is politically expedient, diversity and its management is an important facet of the performance of identity.

description: A new genus of Foraminifera (Miliolata, Cornuspiroidea, Neodiscidae) is erected from the late Guadalupian (Capitanian = Midian) to Lopingian sedimentary succession of the island of Hydra (Greece). It represents an important phylogenetic form, probably at the origin of several genera (or subfamilies of the authors) that became relatively widespread during the Lopingian (Late Permian). Glomomidiella n. gen. is characterized by an entirely glomospiral coiling and rudimentary pseudoseptation.

description: Eight almost complete medium-large sized (about 33 cm in s.l.) fossil fishes, belonging to the family Colobodontidae, are described from the Pelsonian (Anisian, Middle Triassic) of South China. Their cranial and postcranial features fit those of the genus Colobodus Agassiz, 1844 from the western Tethys. However, they are older than the previously known Colobodus species and, furthermore, they come far from the western Tethys, where most colobodontids have been found so far. The significance of our new findings, beyond the erection of a new species, lies in the fact that they are the first definite record of Colobodus outside the western Tethyan faunal province, and represent the oldest unequivocal colobodontids worldwide, as well as suggest that they could have originated in the East rather than the western Tethys, as previously thought.

SELECTED AMMONOID FAUNA FROM PRATI DI STUORES/STUORES WIESEN AND RELATED SECTIONS ACROSS THE LADINIAN-CARNIAN BOUNDARY (SOUTHERN ALPS, ITALY)

description: The ammonoid fauna of the Prati di Stuores/Stuores Wiesen section (Dolomites, north-eastern Italy) was studied in detail. This section was proposed as stratotype for the Carnian GSSP, with the first appearance of Daxatina cf. canadensis as primary marker, based on preliminary data. The validity of this proposal is confirmed by the present study, which integrates collections from the Prati di Stuores/Stuores Wiesen section and from others, particularly Bec de Roces (Passo Campolongo) and Antersass (Badia Valley). Ammonoids collected in these localities belong to three biostratigraphic units: regoledanus, canadensis and aon subzones. These subzones constitute, in the Southern Alps, the Ladinian/Carnian boundary interval. Regoledanus Subzone: the north American species Zestoceras enode is most probably documented in this biostratigraphic interval. Canadensis Subzone: the base is marked by the first appearance of Daxatina canadensis, and at least, another north American species, Daxatina laubei, seems to be present. Two species of Zestoceras were found: Z. barwicki e Z. lorigae sp.n. Two species of Trachyceras, distinct from T. aon, are represented in the canadensis Subzone: T. muensteri and T. bipunctatum. These species predate the first appearance of Trachyceras, justifying the canadensis Subzone to be included in the Carnian also on the basis of nomenclatural stability. Other significant taxa of this subzone are Rossiceras? armatum and Sirenotrachyceras thusneldae. Aon Subzone: the ammonoid fauna of this subzone is extensively treated in existing literature and thus not further discussed. Taxonomical notes and stratigraphic consequences: the new subfamily Anolcitinae (family Trachyceratidae) is erected. At present, Frankites regoledanus, F. apertus and F. sp. A have been recognized in the Southern Alps. The lectotype of Ammonites (Trachyceras ?) Regoledanus was defined. The latter species is exclusive of the regoledanus Subzone, whereas the distribution of the two other species encompasses the defined GSSP. The shell morphology of F. apertus and the north American species F. sutherlandi is identical. The suture line is also comparable, hence the two species are considered synonyms. This synonymy is relevant for long-distance correlations. The lectotypes of Trachyceras ruturanum and T. laricum were also defined.

To analyze different diffusive mechanisms, the water temperature was varied from $210\leq T\leq 380$~K. The results of our simulations reveal that water present a non-Arrhenius to Arrhenius diffusion crossover. The confinement shifts the diffusion transition to higher temperatures when compared with the bulk system. In addition, for narrower nanotubes, water diffuses in a single line which leads to a mobility independent of the activation energy.

We find that our model describes all inelastic scattering charged lepton data, the average of JLAB resonance data, and neutrino data at all Q2. This model is currently used by current neutrino oscillation experiments in the few GeV region.

Bounds on Crossing Symmetry

Subjects: subject: High Energy Physics - Theory (hep-th)

description: Proposed in 1954 by Gell-Mann, Goldberger, and Thirring, crossing symmetry postulates that particles are indistinguishable from anti-particles traveling back in time. Its elusive proof amounts to demonstrating that scattering matrices in different crossing channels are boundary values of the same analytic function, as a consequence of physical axioms such as causality, locality, or unitarity. In this work we report on the progress in proving crossing symmetry on-shell within the framework of perturbative quantum field theory. We derive bounds on internal masses above which scattering amplitudes are crossing-symmetric to all loop orders. They are valid for four- and five-point processes, or to all multiplicity if one allows deformations of momenta into higher dimensions at intermediate steps.

description: In the Mount Messapion area (Chalkida, Greece) a continuous and expanded section of Triassic/Jurassic (T/J) limestone is exposed. This section consists of a 710 m thick pile of shallowing-upward peritidal cycles; the persistence of the facies and the lack of paleoenvironmental changes across the T/J boundary allowed studying the distribution of shallow water microfossils. The T/J boundary is placed in the upper part of the section defined by correspondence with (i) the last occurrence of Triasina hantkeni, (ii) the abrupt disappearance of megalodontid faunas and (iii) the presence of Early Jurassic microfossil assemblages. This paleontological reorganization happens suddenly, it is not controlled by any facies change, and surprisingly, it seems to produce no evident modification in the vertical stacking pattern of the cycles. A detailed facies analysis, performed along a 290 m thick stratigraphic interval (60 m above the T/J boundary and 230 m below), allowed the recognition of peritidal cycles: five different elementary cyclothemes are described and their distribution along the section is given. This integrated stratigraphic study attempts to highlight the relationship between the changes of carbonate producers and sea level fluctuations across the T/J boundary.

description: We study an asymptotic behavior of a special correlator known as the Emptiness Formation Probability (EFP) for the one-dimensional anisotropic XY spin-1/2 chain in a transverse magnetic field. This correlator is essentially the probability of formation of a ferromagnetic string of length $n$ in the antiferromagnetic ground state of the chain and plays an important role in the theory of integrable models. For the XY Spin Chain, the correlator can be expressed as the determinant of a Toeplitz matrix and its asymptotical behaviors for $n \to \infty$ throughout the phase diagram are obtained using known theorems and conjectures on Toeplitz determinants. We find that the decay is exponential everywhere in the phase diagram of the XY model except on the critical lines, i.e. where the spectrum is gapless. In these cases, a power-law prefactor with a universal exponent arises in addition to an exponential or Gaussian decay. The latter Gaussian behavior holds on the critical line corresponding to the isotropic XY model, while at the critical value of the magnetic field the EFP decays exponentially. At small anisotropy one has a crossover from the Gaussian to the exponential behavior. We study this crossover using the bosonization approach.

THE HETTANGIAN SHALLOW WATER CARBONATES AFTER THE TRIASSIC/JURASSIC BIOCALCIFICATION CRISIS: THE ALBENZA FORMATION IN THE WESTERN SOUTHERN ALPS

Subjects: Carbonate platform facies; Early Hettangian; Lombardy Basin; Calcified cyanobacteria

description: This study investigates the stratigraphic and sedimentologic setting of an early Hettangian carbonate platform in the Lombardy Basin, taking into account the Triassic-Jurassic (Tr-J) post-crisis evolution and the geodynamic setting related to the beginning of the Early Jurassic rifting. The historical name of this platform ("Conchodon Dolomite"), not adequate for the absence of Conchodon and for the mainly calcareous lithology, has been replaced with Albenza Formation. The depositional model of this carbonate platform unit is coherent with a leeward Great Bahama Bank-type environment, without any reefs facing deep water environments. The unusual abundance of ooids and marine cements, in the basal progradational ramp-type margins, reflects temporal variation in the saturation state of seawater after the Tr-J crisis, possibly due to marine calcified cyanobacteria blossom. The absence of biotically induced margins related to the (biocalcification) Tr-J crisis and the concomitant tectonic fragmentation, with different subsidence rates of the Tethyan passive margin, conditioned the drowning and the eastward retrogradation of the Albenza platform.

description: We investigate electromagnetically induced transparency (EIT) and Autler-Townes (AT) splitting in Rydberg rubidium atoms for a six-level excitation scheme. In this six-level system, one radio-frequency field simultaneously couples to two high-laying Rydberg states and results in interesting atomic spectra observed in the EIT lines. We present experimental results for several excitation parameters. We also present two theoretical models for this atomic system, where these two models capture different aspects of the observed spectra. One is a six-level model used to predict dominant spectral features and the other a more complex eight-level model used to predict the full characteristics of this system. Both models shows very good agreement with the experimental data.

description: Mit dem Research Infrastructure Self-Evaluation (RISE)-Modell für die Erarbeitung einer Forschungsdaten-Strategie im Projekt „FDMentor“ (2017-2019) und der Entwicklung disziplinspezifischer FDM-Services am Beispiel der Humanwissenschaftlichen Fakultät im Projekt „FDNext“ (2021-2023) wurden an der Universität Potsdam bereits grundlegende strategische wie fakultätsspezifische Strukturen im Forschungsdatenmanagement geschaffen. Die Ergebnisse und Erfahrungen aus beiden Projekten zeigen allerdings, dass Forschende und Studierende bei der Implementierung von FDM und der Umsetzung von Open- und FAIR-Data-Prinzipien noch besser unterstützt werden müssen. FDM-Services der Hochschule sowieAngebote von Konsortien der Nationalen Forschungsdateninfrastruktur (NFDI) werden von den Forschenden noch nicht ausreichend zur Kenntnis genommen. Oft blockiert ein vorherrschender Zeitmangel die Auseinandersetzung mit FDM-Diensten und Richtlinien und somit deren Anwendung. Zudem werden FDM- und FAIR-Data-Prinzipien in hochschulspezifischen Strukturen wie Berufungsverfahren, Promotionskolloquien oder Qualifikationsarbeiten bisher nicht explizit berücksichtigt.

Ziel des Arbeitspaketes der Universität Potsdam des DFG-Verbundprojektes FDLink (2024 –2027) ist deshalb, den Mehrwert sowie die Relevanz von FDM in den Anwendungsfeldern 1) Hochschullehre, 2) Promotionsphase, 3) Anreizsysteme sowie 4) einerseits hochschulinterne (bspw. FDM-Kontaktpunkt, Data Stewards in strukturierten Projekten) und andererseits externe FDM-Supportstrukturen (bspw. dem Projekt der NFDI-Sektion „Common Infrastructures“) effizient zu schärfen.

In dem Poster werden Methoden und Vorgehensweisen für die Umsetzung dieser Prozesse vorgestellt. Dazu gehören u. a. die Anwendung eines nachnutzbaren Frameworks für Fakultäten und FDLink-Fachforen, die Stakeholder überregionaler FDM Akteure (European Open Science Cloud, NFDI, Datenkomepetenzzentren etc.) mit den FDM-Kontaktstellen der Hochschulen und ihrer Fachbereiche vernetzen sollen.

FDLink (2024-2027) wird gefördert von der DFG (Project Number: 534689364).

Subjects: Early Jurassic; Calcareous Nannofossils; Calcari e marne a Posidonia; Tuscan Nappe; Tuscany; Italy

description: In this paper is for the first time dated the inception of the Lower Jurassic marly sedimentation and the lower Toarcian black shales in the Tuscan Nappe, based on semiquantitative analysis of the calcareous nannofossils recovered from the Calcare selcifero di Limano/Calcari e marne a Posidonia transition and the lower part of this latter unit. The boundary between these formations lies within the nannofossil NJT5 Lotharingius hauffii Zone (uppermost Pliensbachian to lower Toarcian), the lower portion of the Calcari e marne a Posidonia ranges from the nannofossil NJT5 Lotharingius hauffii Zone to the NJT7 Discorhabus striatus Zone (middle Toarcian) and the organic-rich interval lies in the nannofossil NJT6 Carinolithus superbus Zone (lower Toarcian). Consequently, the changes from carbonate-dominated to marly-dominated sedimentation (NJT5 Zone) and the black shales accumulation (NJT6 Zone) in the Tuscan and Umbria-Marche basins are two coeval sedimentary events.

description: Στην παρούσα μελέτη επιχειρείται να σκιαγραφηθεί μια πτυχή της διπλωματικής παρουσίας της Βενετίας στην Οθωμανική Αυτοκρατορία. Θέμα της είναι ο θεσμός του Βενετού βαΐλου (πρεσβευτή) στην Οθωμανική Αυτοκρατορία και οι βενετοτουρκικοί πόλεμοι κατά το διάστημα από τον 15ο ως τον 18ο αι. Η εργασία στηρίχτηκε σε βοηθήματα και δημοσιευμένες πηγές, που στην πλειοψηφία τους ήταν οι εκθέσεις των ίδιων των βαΐλων. Συγκεκριμένα μελετούνται οι αρμοδιότητες και τα καθήκοντα με τα οποία ήταν επιφορτισμένος ο βάιλος, καθώς δίνεται και μια εικόνα του τρόπου ζωής του στην Κωνσταντινούπολη. Επιπλέον, καταγράφονται και οι σχέσεις που διατηρούσε με τις εκάστοτε οθωμανικές κυβερνήσεις κατά τους επτά βενετοτουρκικούς πολέμους.
description: In the present survey there is an attempt to outline one aspect of the diplomatic presence of Venice in the Ottoman Empire. The subject of the survey is the the institution of Venetian bailo (ambassador) in the Ottoman Empire and the Venetian-Turkish Wars during the period between the 15th and 18th century. The project was based on respective books and public sources the majority of which were reports of the Venetian bailos themselves. Specifically, the issues examined are the responsibilities and the duties which the baili were entrusted with and a view of their way of life in Constantinople is also presented. Moreover, the relations that they maintained with the ottoman governments during the Venetian - Turkish Wars are also reported.
Ultrafast spin dynamics in inhomogeneous systems: a density-matrix approach applied to Co/Cu interfaces

description: Ultrafast spin dynamics on femto- to picosecond timescales is simulated within a density-operator approach for a Co/Cu bilayer. The electronic structure is represented in a tight-binding form; during the evolution of the density operator, optical excitation by a femtosecond laser pulse, coupling to a bosonic bath as well as dephasing are taken into account. Our simulations corroborate the importance of interfaces for ultrafast transport phenomena and demagnetisation processes. Moreover, we establish a reflow from Cu $d$ orbitals across the interface into Co $d$ orbitals, which shows up prominently in the mean occupation numbers. On top of this, this refilling manifests itself as a minority-spin current proceeding several layers into the Cu region. The present study suggests that the approach captures essential ultrafast phenomena and provides insight into microscopic processes.

description: To simulate a quantum system with continuous degrees of freedom on a quantum computer based on quantum digits, it is necessary to reduce continuous observables (primarily coordinates and momenta) to discrete observables. We consider this problem based on expanding quantum observables in series in powers of two and three analogous to the binary and ternary representations of real numbers. The coefficients of the series ("digits") are, therefore, Hermitian operators. We investigate the corresponding quantum mechanical operators and the relations between them and show that the binary and ternary expansions of quantum observables automatically leads to renormalization of some divergent integrals and series (giving them finite values).

description: This paper deals with radiolarian biostratigraphy of the Calcare Selcifero di Fonzaso at the type-section of Ponte Serra (Southern Alps, Italy). The Ponte Serra section is located on the easternmost part of the Trento Plateau and represents an early-drowned sector that marks the transition to the Belluno Trough.The Calcare Selcifero di Fonzaso consists of pelagic siliceous limestones of Middle to Late Jurassic age for a total thickness of about 70 m. A 24 metres thick package of resedimented limestone is interstratified. This research is focused on the lowermost part, 9 metres thick, that mainly consists of red and green siliceous micrites with interbedded clay beds and abundant chert lenses and nodules. The studied interval lies between the lower member of the Rosso Ammonitico Veronese Formation below and the resedimented limestone above. The recovered radiolarian assemblages indicate a Callovian age for the base of the Calcare Selcifero di Fonzaso. Correlation with other sections of the Trento Plateau reveals a significant diachronism in siliceous sedimentation that we relate to highly irregular sea-bottom paleotopography. The base of siliceous deposits can be even older (Bathonian) on the eastern margin of the Trento Plateau, but younger (Oxfordian) on its western margin. The Callovian succession of the Belluno Trough consists of radiolarian-bearing micrite alternating with oolitic limestone. The oolitic sands that filled in the Belluno Trough during the Middle Jurassic prograded over the eastern margin of the Trento Plateau in the early Oxfordian.

COUPLING AMPULLINID GASTROPODS: SEXUAL BEHAVIOUR FROZEN IN PALAEOGENE DEPOSITS OF NORTHERN ITALY

description: Couples of the ampullinid gastropods Globularia (Eocernina) vulcani (Brogniart, 1823), Amaurellina (Crommium) angustata (Grateloup, 1827) and Amaurellina (Pachycrommium) cf. suessoniensis (d'Orbigny, 1850), composed of dimorphed shells tightly conjoined at the apertures, from the Palaeogene (Eocene and Oligocene) marine successions of northern Italy, are interpreted as buried while mating, specimens being "frozen" while suddenly covered by a mass of sediment. Violent depositional events were responsible for their rapid burial, primarily by volcanoclastics, the formation of which had also involved acidification. The consequent poisoning of sea water and/or overwarming beyond the range in which the gastropods could survive, induced mass mortality. A similar set of conditional circumstances is also discussed for differently sized coupled specimens of Ampullinopsis crassatina (Lamarck, 1804), preserved with their shells slightly apart but with their apertures almost in contact. With reference to the catastrophic eruption of Vesuvius in A.D. 79, when Pompei was buried under tephra, it is thought that volcanic activity caused the death and burial of all these pairing gastropods in a "Pompeian" way.
