description: The new locality with dinosaur footprints has been discovered in the port of Karigador village in Istria. The site is situated in peritidal limestones of late Cenomanian age. The track-bearing horizon is bioclastic wackestone-packstone deposited in a subtidal environment. A single trackway which consist of 28 pairs of footprints and a group of 4 track pairs was registered at the site. Trackways belong to quadrupedal dinosaurs and are assigned to sauropods. Oval-circular shaped footprints represent the pedal prints and horseshoe-semicircular shaped ones represent the manus prints. The trackway is of narrow-gauge type with outwardly rotated manus and pedal prints. The average length of the pedal prints is 33 cm what indicates the length of the individual of app. 10 m. The preferred gait of the individual was a normal walk, taking normal strides with a speed of around 3 km/h. The trackmaker was a non-titanosaurian sauropod. Together with the other late Cenomanian sauropod localities in Istria (Fenoliga and Ladin Gaj), the Karigador site represents an example of sauropod tracks in a carbonate platform environment which can be assigned to Brontopodus ichnofacies.

description: Super-high-\k{appa} materials that exhibit exceptionally high dielectric permittivity are recognized as potential candidates for a wide range of next-generation photonic and electronic devices. Generally, the high dielectricity for achieving a high-\k{appa} state requires a low symmetry of materials so that most of the discovered high-\k{appa} materials are symmetry-broken crystals. There are scarce reports on fluidic high-\k{appa} dielectrics. Here we demonstrate a rational molecular design, supported by machine-learning analyses, that introduces high polarity to asymmetric molecules, successfully realizing super-high-\k{appa} fluid materials (dielectric permittivity, ε > 104) and strong second harmonic generation with macroscopic spontaneous polar ordering. The polar structures are confirmed to be identical for all the synthesized materials. Our experiments and computational calculation reveal the unique orientational structures coupled with the emerging polarity. Furthermore, adopting this strategy to high-molecular-weight systems additionally extends the novel material category from monomer to polar polymer materials, creating polar soft matters with spontaneous symmetry breaking.
THE OLDEST ESCHRICHTIID MYSTICETE AND A NEW MORPHOLOGICAL DIAGNOSIS OF ESCHRICHTIIDAE (GRAY WHALES)

Publisher: name: Università degli Studi di Milano

description: A close inspection of the dentary of Eschrichtius robustus (Cetacea, Mysticeti, Eschrichtiidae) revealed a peculiar organization of the coronoid region. Similar morphologies have been observed in two specimens which are respectively from the Early Pliocene of Piedmont and the Late Miocene of Apulia, Italy. The peculiar organization of the coronoid region consists of the presence of a satellite process parallel or slightly anterior to the coronoid process with a groove interposed between them. The morphology of the dentary is used here to emend the diagnosis of the family Eschrichtiidae and for including the above Italian specimens in this family. Such an emendation is due to the unique mandibular organization shared by Eschrichtius robustus and the Italian specimens mentioned above. The new diagnosis allows the establishment of the new genus Archaeschrichtius from the Late Miocene of Apulia, which represents the oldest eschrichtiid mysticete to be formally described up to now. Italian specimens extends back to the Late Miocene the fossil record of Eschrichtiidae and document aspects of feeding evolution within Eschrichtiidae for the first time.

description: We study a system of two qubits interacting with a common environment, described by a two-spin boson model. We demonstrate two competing roles of the environment: inducing entanglement between the two qubits and making them decoherent. For the environment of a single harmonic oscillator, if its frequency is commensurate with the induced two-qubit coupling strength, the two qubits could be maximally entangled and the environment could be separable. In the case of the environment of a bosonic bath, the gap of its spectral density function is essential to generate entanglement between two qubits at equilibrium and for it to be used as a quantum data bus.

description: The rapid evolution of electronics, digital media, advanced materials, and other areas of technology, is opening up unprecedented opportunities for musical interface inventors and designers. The possibilities afforded by these new technologies carry with them the challenges of a complex and often confusing array of choices for musical composers and performers. New musical technologies are at least partly responsible for the current explosion of new musical forms, some of which are controversial and challenge traditional definitions of music. Alternative musical controllers, currently the leading edge of the ongoing dialogue between technology and musical culture, involve many of the issues covered at past CHI meetings. This workshop brings together interface experts interested in musical controllers and musicians and composers involved in the development of new musical interfaces.

description: This work describes a new bovid, Asoletragus gentryi n. gen. et sp., from the late Pliocene/early Pleistocene fossiliferous fissure fillings (Cava VI,3) in the karst network at  Monte Tuttavista (Sardinia, Italy). It differs from other genera in its straight, almost conical, horn-cores, which diverge slightly from the sagittal plane, are very close together at their bases and slant strongly backwards (nearly parallel to the glenoid surface of the temporal bone). The very peculiar shape and position of these horn-cores render their phylogenetic relationship with other taxa from the Miocene of Europe and other circum-Mediterranean countries uncertain. Given the global features of the horn-cores and the absence of any alcelaphine-like tooth in the Monte Tuttavista samples, the hypothesis that Asoletragus belongs to an archaic "Caprinae" cannot be ruled out, despite the presence of quite a large frontal sinus rising through the pedicel and at least one-third of the horn-core proper. Pending the discovery of other fossils from this taxon, one may only hypothesize regarding its phylogeny.

description: We provide a systematic revision of the late Miocene caprine genus Sporadotragus Kretzoi, 1968, the type-species of which was described from Samos under the specific epithet schafferi. It is distinct from the poorly known Pseudotragus. Some specimens from Samos are rather distinctive, but the whole morphological variation there encompasses that of Palaeoryx parvidens from Pikermi, and we follow earlier authors in considering the two names as synonymous. New material from two late Miocene localities of south-western Bulgaria, Kalimantsi and Strumyani, is referred to a new species, S. vasili, which is more primitive than the Greek one in some skull features, but not in the horn-core morphology.

 Adult females of all Coccus species from Macaranga share the features of areolations on the dorsal derm, a cluster of preopercular pores anterior to the anal plates, a broad submarginal band of a ventral tubular ducts, and pregenital disc-pores confined to the area lateral to the vulva. Prior to molecular phylogenetic studies, we considered erecting a new genus for these Macaranga -associated coccids but, as discussed in the Introduction above, their close genetic relationship to C. hesperidum (the type species of Coccus) made this action untenable, despite the morphological distinctness of the Macaranga coccid species from C. hesperidum. For example, adult females of C. hesperidum lack ventral tubular ducts in the submarginal area of the body (prominent in the Macaranga coccids) and possess dorsal tubercles (lacking in the Macaranga -associated species).

MORPHOLOGY, TAXONOMY AND DISTRIBUTION OF THE CRETACEOUS CORAL GENUS PREVERASTRAEA (LATE BARREMIAN-CENOMANIAN; SCLERACTINIA)
Creators: name: LÖSER, HANNES
Publisher: name: Università degli Studi di Milano

description: The Cretaceous coral genus Preverastraea is being revised, mainly on the basis of sample material. This cerioid, occasionally astreoid or phaceloid, genus is characterised by round or polygonal calices, compact septa in a regular hexameral symmetry and lonsdaleoid septa. The wall is of the same structure as the septa. The genera Bogdanovicoenia, Paraacanthogyra, and Saxuligyra are considered synonyms of Preverastraea. Related genera are Aulastraeopora and Apoplacophyllia, which only differ by their solitary or dendroid growth forms. There are altogether 13 species of Preverastraea. The genus, which occurred worldwide, is restricted to the period from the Late Barremian to the Late Cenomanian, being most common in the Aptian to Early Albian. Eighty-three samples are either known from the literature or have been to hand. This makes Preverastraea a rather rare genus.

description: We study the gravitational collapse of a spherically symmetric anisotropic relativistic star within Einstein theory of gravity making use of one of our recently developed collapsing stellar models [{\it Astrophys. Space Sci.} {\bf361} 99 (2016)]. The final state of continual gravitational collapse of a massive star under regular initial conditions is analyzed in terms of the formation of black holes. To study the evolution of an anisotropic star undergoing gravitational collapse, it is assumed that the dissipation process happens in the form of radial heat-flux. The interior space-time is described by static metric matched at the boundary with Vaidya metric that describes the exterior to the radiating star. The initial static configuration is described by the relativistic solution obtained by Paul and Deb [{\it Astrophys. Space Sci.} {\bf354} 421 (2014)]. The impact of anisotropy on the dynamical gravitational collapse of a massive star is studied. The relativistic causal heat transport equation of the Maxwell-Cattaneo equation is utilized to show the dependence of anisotropy on the temperature profile of the collapsing system.

description: Experimental tests of gravity performed in the solar system show a good agreement with general relativity. The latter is however challenged by the Pioneer anomaly which might be pointing at some modification of gravity law at ranges of the order of the size of the solar system. As this question could be related to the puzzles of ``dark matter'' or ``dark energy'', it is important to test it with care. There exist metric extensions of general relativity which preserve the well verified equivalence principle while possibly changing the metric solution in the solar system. Such extensions have the capability to preserve compatibility with existing gravity tests while opening free space for the Pioneer anomaly. They constitute arguments for new mission designs and new space technologies as well as for having a new look at data of already performed experiments.

description: In late Paleocene-Eocene times, in the Tethyan area, the shallowest and most restricted carbonates deposited between the intertidal zone and the lower limit of the upper photic zones are characterized by Spirolina-dominated facies. This extremely shallow-water carbonate facies is recorded from the Cenomanian to the Miocene in the Tethyan realm with similar sedimentological characters and similar spiroliniform epiphytic taxa. All these taxa can be considered to reflect some kind of vicariance through time. In Southern Italy this peculiar facies is represented by the Trentinara Formation (Lower-Middle Eocene); in several stratigraphic sequences of this formation, three levels containing alveolinids were identified. The first is well known in the literature and allows us to assign the lowermost part of the Formation to the lowermost Ypresian (bio-chronozone SBZ 6, Alveolina ellipsoidalis zone); the second is not age diagnostic because alveolinids are rare and poorly preserved; the third allows the age of the upper part of the Trentinara Formation to be established as Early Lutetian (bio-chronozone SBZ 13, Alveolina stipes zone). The exact age of the top of the formation is still unclear, but probably falls within the Lutetian-Priabonian interval. The geographic locations of the most significant shallow-water carbonates of Early-Middle Eocene age, cropping out in the southern Apennines, have led to a first attempt to map their distribution within the central gyre of western Tethys.

description: We present a new suite of mock galaxy catalogs mimicking the low-redshift Universe, based on an updated halo occupation distribution (HOD) model and a scaling relation between optical properties and the neutral hydrogen (HI) content of galaxies. Our algorithm is constrained by observations of the luminosity function and luminosity- and colour-dependent clustering of SDSS galaxies, as well as the HI mass function and HI-dependent clustering of massive HI-selected galaxies in the ALFALFA survey. Mock central and satellite galaxies with realistic values of $r$-band luminosity, $g-r$ and $u-r$ colour, stellar mass and HI mass are populated in an $N$-body simulation, inheriting a number of properties of the density and tidal environment of their host halos. The host halo of each central galaxy is also `baryonified' with realistic spatial distributions of stars as well as hot and cold gas, along with the corresponding rotation curve. Our default HOD assumes that galaxy properties are a function of group halo mass alone, and can optionally include effects such as galactic conformity and colour-dependent galaxy assembly bias. The mocks predict the relation between the stellar mass and HI mass of massive HI galaxies, as well as the 2-point cross-correlation function of spatially co-located optical and HI-selected samples. They enable novel null tests for galaxy assembly bias, provide predictions for the HI velocity width function, and clarify the origin and universality of the radial acceleration relation in the $Λ$CDM framework.

Lithophyllum contii Mastrorilli, 1967 is transferred to the subfamily Mastophoroideae and the new combination Neogoniolithon contii is proposed. L. giammarinoi, L. embergeri, M. flexile and M. rigidum are considered to be younger heterotypic synonyms of L. contii, originally established on the basis of anatomical details herein considered to be artefacts due to improper orientation of studied thalli.
Each species is critically analysed on the basis of original Mastrorilli’s collections (Genoa University, Dip.Te.Ris) and additional material collected at the type localities.

description: We consider the problem of recognizing AT-free graphs. Although there is a simple O(n3) algorithm, no faster method for solving this problem had been known. Here we give three different algorithms which have a better time complexity for graphs which are sparse or have a sparse complement; in particular we give algorithms which recognize AT-free graphs in O(n m} + n2), O( m}3/2 + n2), and O(n2.82 + n m). In addition we give a new characterization of graphs with bounded asteroidal number by the help of the knotting graph, a combinatorial structure which was introduced by Gallai for considering comparability graphs.
The gravitational collapse of ONe electron-degenerate cores and white dwarfs: the role of $^{24}$Mg and $^{12}$C revisited

description: The final stages of the evolution of electron--degenerate ONe cores, resulting from carbon burning in ``heavy weight'' intermediate--mass stars ($8 M_{\sun}\la M \la 11 M_{\sun}$) and growing in mass, either from carbon burning in a shell or from accretion of matter in a close binary system, are examined in the light of their detailed chemical composition. In particular, we have modelled the evolution taking into account the abundances of the following minor nuclear species, which result from the previous evolutionary history: $^{12}$C, $^{23}$Na, $^{24}$Mg, and $^{25}$Mg. Both $^{23}$Na and $^{25}$Mg give rise to Urca processes, which are found to be unimportant for the final outcome of the evolution. $^{24}$Mg was formerly considered a major component of ONe cores (hence called ONeMg cores), but updated evolutionary calculations in this mass range have severely reduced its abundance. Nevertheless, we have parameterized it and we have found that the minimum amount of $^{24}$Mg required to produce NeO burning at moderate densities is $\sim 23%$, a value exceedingly high in the light of recent evolutionary models. Finally, we have determined that models with relatively small abundances of unburnt carbon ($X(^{12}$C)$\sim 0.015$) could be a channel to explosion at low to moderate density ($\sim 1\times 10^9$ g cm$^{-3}$). This is clearly below the current estimate for the explosion/collapse threshold and would have interesting consequences.

description: Extended full-waveform inversion (FWI) has shown promising results for accurate estimation of subsurface parameters when the initial models are not sufficiently accurate. Frequency-domain applications have shown that the augmented Lagrangian (AL) method solves the inverse problem accurately with a minimal effect of the penalty parameter choice. Applying this method in the time domain, however, is limited by two main factors: (1) The challenge of data-assimilated wavefield reconstruction due to the lack of an explicit time-stepping and (2) The need to store the Lagrange multipliers, which is not feasible for the field-scale problems. We show that these wavefields are efficiently determined from the associated data (projection of the wavefields onto the receivers space) by using explicit time stepping. Accordingly, based on the augmented Lagrangian, a new algorithm is proposed which performs in "data space" (a lower dimensional subspace of the full space) in which the wavefield reconstruction step is replaced by reconstruction of the associated data, thus requiring optimization in a lower dimensional space (convenient for handling the Lagrange multipliers). We show that this new algorithm can be implemented efficiently in the time domain with existing solvers for the FWI and at a cost comparable to that of the FWI while benefiting from the robustness of the extended FWI formulation. The results obtained by numerical examples show high-performance of the proposed method for large scale time-domain FWI.

description: We investigate spreading and recovery of disease in a square lattice, and in particular, emphasize the role of the initial distribution of infected patches in the network, on the progression of an endemic and initiation of a recovery process, if any, due to migration of both the susceptible and infected hosts. The disease starts in the lattice with three possible initial distribution patterns of infected and infection-free sites, infected core patches (ICP), infected peripheral patches (IPP) and randomly distributed infected patches (RDIP). Our results show that infection spreads monotonically in the lattice with increasing migration without showing any sign of recovery in the ICP case. In the IPP case, it follows a similar monotonic progression with increasing migration, however, a self-organized healing process starts for higher migration, leading the lattice to full recovery at a critical rate of migration. Encouragingly, for the initial RDIP arrangement, chances of recovery are much higher with a lower rate of critical migration. An eigenvalue based semi-analytical study is made to determine the critical migration rate for realizing a stable infection-free lattice. The initial fraction of infected patches and the force of infection play significant roles in the self-organized recovery. They follow an exponential law, for the RDIP case, that governs the recovery process. For the frustrating case of ICP arrangement, we propose a random rewiring of links in the lattice allowing long-distance migratory paths that effectively initiate a recovery process. Global prevalence of infection thereby declines and progressively improves with the rewiring probability that follows a power law with the critical migration and leads to the birth of emergent infection-free networks.

Eight-year-olds’ construction of narratives and levels of literacy
Creators: name: Dunn, Sheri Lynn
Publisher: name: University of British Columbia
Year: 2009

description: The purpose of this study was to explore the ability of 8-year-old children to construct oral narratives from a wordless picture book, "Frog. Where Are You?" (Mayer, 1969) and to investigate whether there was a correlation between the children's narrative ability and reading comprehension. Specifically, there were two goals of this study: The first was to explore the way children globally organized their narratives in terms of plot components (I Onset, II Unfolding, and III Resolution), their narration specific events, and their methods of linguistically combining clauses, and linguistically packaging events; and to compare these characteristics to the narratives of 5-year-olds and 9-year-olds reported in Berman and Slobin (1994). The second was to attempt to correlate these characteristics with the children's performance on a reading comprehension assessment. Twelve children between the ages of 8;1.0 and 9;2.0 participated in this study, 6 of whom were in second-grade and of 6 whom were in third grade. Six of the children were part of previous narrative studies conducted at the University of British Columbia. Each child narrated the story twice, with one week between each telling, during which the children "read" the book with or to their caregiver(s). The children's reading abilities were measured using the Gates-MacGinite Reading Test (MacGinitie & MacGinitie, 1989). Results showed that with respect to the use of plot components these children's narratives were generally comparable to those of the 9-year-old children reported by Berman and Slobin. Their use of event components was proportionately higher than Berman and Slobin's 9-year-olds'. The majority of the children performed above grade level on the reading assessment, and little variation was found between reading scores. Therefore, grade level was used as an indirect measure of literacy exposure. An association was found between grade level and inclusion of plot components, as well as, the use of 'linguistically mature' methods of event packaging. No association was found between grade level and the inclusion of plot components, use of multiclause sentences, or linguistically mature methods of syntactically combining sentences.

description: Eosclerocalyptus tapinocephalus (Cabrera) from the Huayquerian (Late Miocene) of the Pampean region, was known previously only from the type material. The recent finding of a well preserved specimen, mainly the caudal tube and limb bones, allows improved knowledge of its morphology and comparison with related forms, particularly Eosclerocalyptus proximus (Moreno and Mercerat) of the "Araucanian" (Late Miocene-Early Pliocene) from the northwest of Argentina, and Neosclerocalyptus Paula Couto (Pleistocene of Argentina, Paraguay and Uruguay). Our observations support the recent proposal of Perea to include Hoplophractus Cabrera within Eosclerocalyptus C. Ameghino. Morphologically, E. tapinocephalus is characterized by: a) the parieto-occipital region of the skull tilting posteriorly; b) the low zygomatic arch descending towards the orbital notch; c) the lateral osteoderms of the dorsal carapace, with anterior peripheral figures of greater development than the posterior ones; d) dorsal carapace of dorsal contour similar to the that of E. proximus; e) caudal tube similar to that of E. proximus but with less development of the small peripheral figures; f) femoral morphology intermediate between Propalaehoplophorus and Neosclerocalyptus. Finally, and from a palaeozoogeographic and stratigraphic point of view, Eosclerocalyptus tapinocephalus represents (together with E. proximus) the first certain species of the tribe Hoplophorini, limited to the Huayquerian Stage (Late Miocene; ca. 8.7-6.8 Ma) of the central area of the Buenos Aires province, characterized by the presence of open environments (savannas, grasslands and herbaceous steppes).

description: The combination of two-dimensional (2D) materials into heterostructures enabled the formation of atomically thin devices with designed properties. To achieve a high density, bottom-up integration, the growth of these 2D heterostructures via van der Waals epitaxy (vdWE) is an attractive alternative to the currently mostly employed mechanical transfer, which is still problematic in terms of scaling and reproducibility. However, controlling the location of the nuclei formation remains a key challenge in vdWE. Here, we use a focused He ion beam for a deterministic placement of defects in graphene substrates, which act as preferential nucleation sites for the growth of insulating, 2D hexagonal boron nitride (h-BN). We demonstrate a mask-free, selective-area vdWE (SAvdWE), where nucleation yield and crystal quality of h-BN is controlled by the ion beam parameter used for the defect formation. Moreover, we show that h-BN grown via SAvdWE has electron tunneling characteristics comparable to those of mechanically transferred layers, thereby lying the foundation for a reliable, high density array fabrication of 2D heterostructures for device integration via defect engineering in 2D substrates.

description: We investigate the crossed Andreev reflections between two graphene leads connected by a narrow superconductor. When the leads are respectively of the n-and p- type, we find that electron elastic cotunneling and local Andreev reflection are both eliminated even in the absence of any valley-isospin or spin polarizations. We further predict oscillations of both diagonal and cross conductances as a function of the distance between the graphene-superconductor interfaces.

description: We introduce a new technique for constructing three-dimensional (3D) models of incompressible Riemann S-type ellipsoids and compressible triaxial configurations that share the same velocity field as that of Riemann S-type ellipsoids. Our incompressible models are exact steady-state configurations; our compressible models represent approximate steady-state equilibrium configurations. Models built from this method can be used to study a variety of relevant astrophysical and geophysical problems.

description: Glioma is the most deadly brain tumor with high mortality. Treatment planning by human experts depends on the proper diagnosis of physical symptoms along with Magnetic Resonance(MR) image analysis. Highly variability of a brain tumor in terms of size, shape, location, and a high volume of MR images makes the analysis time-consuming. Automatic segmentation methods achieve a reduction in time with excellent reproducible results. The article aims to survey the advancement of automated methods for Glioma brain tumor segmentation. It is also essential to make an objective evaluation of various models based on the benchmark. Therefore, the 2012 - 2019 BraTS challenges database evaluates state-of-the-art methods. The complexity of tasks under the challenge has grown from segmentation (Task1) to overall survival prediction (Task 2) to uncertainty prediction for classification (Task 3). The paper covers the complete gamut of brain tumor segmentation using handcrafted features to deep neural network models for Task 1. The aim is to showcase a complete change of trends in automated brain tumor models. The paper also covers end to end joint models involving brain tumor segmentation and overall survival prediction. All the methods are probed, and parameters that affect performance are tabulated and analyzed.

description: The conversion efficiency of ultra-thin solar cells based on layered materials has been limited by their open-circuit voltage, which is typically pinned to a value under 0.6 V. Here we report an open-circuit voltage of 1.02 V in a 120 nm-thick vertically stacked homojunction fabricated with substitutionally doped MoS2. This high open-circuit voltage is consistent with the band alignment in the MoS2 homojunction, which is more favourable than in widely-used TMDC heterostructures. It is also attributed to the high performance of the substitutionally doped MoS2, in particular the p-type material doped with Nb, which is demonstrated by the observation of electroluminescence from tunnelling graphene/BN/MoS2 structures in spite of the indirect nature of bulk MoS2. We find that illuminating the TMDC/metal contacts decreases the measured open-circuit voltage in MoS2 van der Waals homojunctions because they are photoactive, which points to the need of developing low-resistance, ohmic contacts to doped MoS2 in order to achieve high efficiency in practical devices. The high open-circuit voltage demonstrated here confirms the potential of layered transition-metal dichalcogenides for the development of highly efficient, ultra-thin solar cells.
NGC 4254: a spiral galaxy entering the Virgo cluster

description: Deep Effelsberg HI spectra of the one-armed, bright Virgo cluster spiral galaxy NGC 4254 are presented.Five different positions were observed in the 21 cm HI line with the Effelsberg 100-m telescope: one in the center and 4 located one HPBW to the NE, NW, SW, and SE, respectively, from the galaxy center. The spectra are compared to existing deep VLA observations, and the single dish and interferometric HI data are used to constrain a dynamical model which includes the effects of ram pressure. The peculiar, one-armed spiral pattern of NGC 4254 and its distorted and kinematically perturbed atomic gas distribution can be explained by a close and rapid encounter ~280 Myr ago with another massive Virgo galaxy, followed by ram pressure stripping that is still ongoing. The stripping occurs almost face-on, since the angle between the disk and the orbital plane is 70 degrees. The galaxy with which NGC 4254 had its encounter is tentatively identified as the lenticular NGC 4262.

description: We conjecture the inversion relations for thermalized solvable interaction round the face (IRF) two dimensional lattice models. We base ourselves on an ansatz for the Baxterization described by the author in the 90's. We solve these inversion relations in the four main regimes of the models, to give the free energy of the models, in these regimes. We use the method of Baxter in the calculation of the free energy of the hard hexagon model. We believe these results to be quite general, shared by most of the known IRF models. Our results apply equally well to solvable vertex models. Using the expression for the free energy we calculate the critical exponent $α$, and from it the dimension of the perturbing (thermal) operator in the fixed point conformal field theory (CFT). We show that it matches either the coset ${\cal O}/{\cal G}$ or ${\cal G}/{\cal O}$, where $\cal O$ is the original CFT used to define the model and $\cal G$ is some unknown CFT, depending on the regime. This agrees with known examples of such models by Huse and Jimbo et al.

Poussiére sur la ville : l’influence de L’étranger de Camus sur le rôle des codes sociaux et littéraires
Creators: name: Abell, Ourania Marthe
Publisher: name: University of British Columbia

description: Dans son livre Surprendre les voix Andre Belleau fait remarquer, entre autres, que les codes socio-culturels et les codes litteraires du Quebec et ceux de l a France s'amalgament dans la litterature quebecoise. Il affirme que la litterature quebecoise a emprunte les codes de la France et que cet acte a "doublement marginalise" cette litterature . Cette idee sert de base a ma these ou je considere deux romans: L'Etranqer d’Albert Camus et Poussiere sur la ville d'Andre Langevin. Commencant par une etude des protagonistes pour elucider comment Langevin a pu bien manipuler les codes socio-culturels et les codes litteraires des deux pays pour passer son message; je ferais ensuite une discussion des femmes fatales des romans de Langevin et Camus dans le deuxieme chapitre. Au coeur de cette discussion sont la couleur, la sensualite et la violence que les femmes fatales exhibent pour faire ce qu'elles desirent. Dans le dernier chapitre j'analyse les elements qui ont une influence sur les protagonistes. Le temps, la religion et le regard de la collectivite ont une puissance certaine a influer sur les agissements des protagonistes. En faisant cette etude j'affirme que Langevin a pu emprunter les codes sociaux et litteraires de Camus, comme Camus a pu les emprunter a d'autres. Les enonces et meme les mots qui nous parviennent ainsi ne sont pas inertes, neutres, sans attaches, comme le dit Bakhtine. Au contraire, ces enonces sont deja des fragments de discours existants, ils sont proprement des enonces de discours (Belleau 167). Dans cette these je demontrerai que justement, il existe plusieurs singularites entre Langevin et Camus et que c'est une chose qui suit la nature des choses.

description: Highly unconventional behavior of the thermodynamic response functions has been experimentally observed in a narrow gap semiconductor samarium hexaboride. Motivated by these observations, we use renormalization group technique to investigate many-body instabilities in the f-orbital narrow gap semiconductors with band inversion in the limit of weak coupling. After projecting out the double occupancy of the f-orbital states, we formulate a low-energy theory describing the interacting particles in two hybridized electron- and hole-like bands. The interactions are assumed to be weak and short-ranged. We take into account the difference between the effective masses of the quasiparticles in each band. Upon carrying out the renormalization group analysis we find that there is only one stable fixed point corresponding to the excitonic instability with time-reversal symmetry breaking for small enough mismatch between the effective masses.

description: We consider the proton structure corrections to hydrogen ground-state hyperfine structure, focusing on a state-of-the-art evaluation of the inelastic nucleon corrections--the polarizability corrections--using analytic fits to the most recent data. We find a value for the fractional correction Delta_{pol} of 1.3 \pm 0.3 ppm. This is 1--2 ppm smaller than the value of Delta_{pol}$ one would deduce using hyperfine splitting data and elastic proton structure corrections obtained from modern form factor fits. In addition, we discuss the derivations of the relevant formulas, paying attention to lepton mass effects and to questions surrounding the use of unsubtracted dispersion relations.

description: We describe and illustrate a partial skull and mandible of a large sabertooth cat from Sahabi, Libya, and refer it to Amphimachairodus aff. A. kabir. A review shows the Miocene Machairodontinae from Africa to be a heterogeneous assemblage, with both small and large forms spanning the entire Late Miocene. The Sahabi form belongs to the group of larger sized taxa, along with A. kabir from Chad and some previously undescribed specimens from the Wembere-Manonga Formation, Tanzania. Both the Sahabi and Chad specimens have relatively slender lower carnassials, similarly to Homotherium, though derived features of the skull and mandible suggest that they are not in the direct ancestry of that genus.
