description:
 An Attic kylix (drinking-cup) with a stemmed base, a deep bowl and twin, upturned loop handles, all upon a concave base. The rim is thin and gently waving. The exterior walls are decorated with black-figure technique on red background: two draped young men in himatia facing each other stand at the side of a swan with open wings, associated with Aphrodite and Apollo. The interior of the bowl is black. Close to the handles, are stylized palmette and floral decorations. Black glazed bands on the body and handles as well as a concentric circle on the base further adorn the piece. The foot is short with a thick disc mostly black except for the lower section. Stylistic remarks: compare with object numbers 127.007 and 127.030?, particularly the left wing of the swan with the beard of the man on 127.007. The style is remarkably similar to that of the Haimon Painter, especially in the rendering of facial features, and feet. Date: 500–450 BCE

description: We investigate nonlinear effects in an electromechanical system consisting of a superconducting charge qubit coupled to transmission line resonator and a nanomechanical oscillator, which in turn is coupled to another transmission line resonator. The nonlinearities induced by the superconducting qubit and the optomechanical coupling play an important role in creating optomechanical entanglement as well as the squeezing of the transmitted microwave field. We show that strong squeezing of the microwave field and robust optomechanical entanglement can be achieved in the presence of moderate thermal decoherence of the mechanical mode. We also discuss the effect of the coupling of the superconducting qubit to the nanomechanical oscillator on the bistability behaviour of the mean photon number.

description: В статье представлен обзор проблем, сложившихся в сфере управления РСЧС и связанных, в первую очередь, с последствиями реорганизации управления на межрегиональном уровне. Показаны недостатки в деятельности РСЧС на уровне Головных ГУ МЧС России, а также их практические последствия, связанные со своевременностью и обоснованностью принятия решений относительно ликвидации последствий ЧС, в особенности межрегионального уровня. Выделены такие проблемы как обеспечение взаимодействия сил МЧС на межрегиональном уровне, отсутствие у Головных ГУ МЧС России достаточных полномочий по распоряжению силами МЧС, в том числе, относящихся к другим регионам. Отмечены также проблемы, связанные с недостатками практического опыта кадрового состава на уровне Головных ГУ МЧС России и в системе управления финансированием постоянно действующих органов МЧС России. Показано, что для решения этих проблем необходимо, в первую очередь, достижение упорядоченности в управлении РСЧС на межрегиональном уровне, организация работы по передаче опыта между сотрудниками МЧС, а также более эффективное управление финансированием межрегиональных подразделений.
Hilltop inflation with preinflation from coupling to matter fields

description: We propose a class of models of supersymmetric hilltop inflation (also called "new inflation") where the initial conditions of the inflaton close to the hilltop are generated through "matter field preinflation". This is achieved via a coupling term between the inflaton and matter fields (i.e. Standard Model fields or a right-handed neutrino). The same coupling also opens up a decay channel for the inflaton into Standard Model fields, which allows efficient reheating of the universe. We discuss the multifield dynamics of the inflaton and matter fields during inflation using the delta N formalism and show under which conditions the model effectively reduces to single-field hilltop inflation during the last 60 e-folds. We also study perturbative reheating through the matter-inflaton coupling for a specific example where the matter field is identified with a right-handed (s)neutrino, and demonstrate that in this case the model can generate the observed baryon asymmetry through nonthermal leptogenesis.

title: Countermonumentality and memory: the case of the Glorieta de Colón monument in Mexico City
Creators: name: Ruiz Peralta, Nadia
Publisher: name: Memorial University of Newfoundland
Year: 2023

description: The Christopher Columbus monument on Reforma Avenue in Mexico City stood for over one hundred years. However, since the turn of the twenty-first century, the monument has become the target of countermonumental actions. This research project questions the entanglement between countermonumentality, collective memory, and heritage through the analysis of the materiality at the site of the monument. Themes of feminism, anti-monumentality, public space appropriation, and the use of archaeological artifacts to construct a state-sanctioned history arose via this study.

Subjects: Black, Past, Slavery, Present, Identity, Afrofuturism.

description: Abstract
This paper delineates Butler's postmodern technique of instilling hope for an Afrofuturistic vision from the state of dystopian social reality in Octavia Estelle Butler's Kindred. Butler is the poster child for establishing black female heroines in science fiction and Afrofuturism as viable identities. The novel, Kindred, describes a white supremacist society in which African Americans are treated as second-class citizens despite having darker skin than white people. Dana, the main character, only makes the difficult decision to travel to her ancestral home after learning about the connections between the freedom of plantation slaves from Rufus, her ancestor. Dana suffers from psychological problems related to heteroclite potential difference, slavery, and racial prejudice that are upheld by the societies of her ancestors' past and present.

description:
 Small black-figure neck-amphora (storage jar) on beige ground of Attic manufacture depicting: (a) Theseus and the Minotaur between woman (Ariadne?) and youth. Theseus on the left, dressed in a short chiton (seemingly without lion skin), hair pulled back, carrying sword in right hand, and holding Minotaur’s arm with left. (b) Satyr and Maenads. Palmette and lotus chain motif on neck, above fretted band; black foot with rays towards solid black band. Stylistic remarks: The example can be attributed to the Light-make class, a group of small neck-amphorae of light manufacture, defined by J. D. Beazley. The general composition and the execution of the single decorative elements (stylised palmettes on the neck, the fretted band, as well as the radiating decoration from the foot to the solid band below the main scene) is extremely close to the style of the Mariani Painter and very close to certain examples attributed to the Painter of Pescia.

We find that PbBi1212 exhibits superconductivity when the Ca concentration $x$ exceeds 0.3. The effective number of holes per Cu atom $n_{\rm eff}$ is well described as $n_{\rm eff}=0.34x$. The highest onset temperature for the superconducting transition attained in the present study is 65 K. The resistivity measurement in a magnetic field reveals that the coherence lengths of Pb1212 ($y=0$) are approximately 25 and 2.7 Å, along the $ab$ plane and the $c$ axis, respectively.

description: Genomic erosion due to hybridisation is a problem which many endemisms face, including Italian pike Esox flaviae and marble trout Salmo marmoratus. These important freshwater species, which naturally occur in the Italian peninsula, are threatened by decades of stocking with non-native commercial lines, namely European pike Esox lucius and brown trout Salmo trutta. While supportive breeding programmes are in place for these species, screening of suitable breeders is based on traditional genetic methods such as microsatellite marker genotyping, which may have limited power to distinguish hybrids. Moreover, such markers are often surveyed through alternative laboratory protocols that can yield inconsistent results amongst research groups and hinder integration of molecular data from different local surveys on a larger biogeographical scale. In this doctoral thesis, I apply high-density Single Nucleotide Polymorphisms (SNPs) to the study of population substructure and genomic landscape within Italian pike, and I develop a large SNP panel to be implemented in a future genotyping array for large-scale genetic monitoring of Italian marble trout populations. In particular, I identified more than 20 million high-quality SNP markers from whole genome sequencing. Using these data sets, I found evidence of introgressive hybridisation in both species and reported a diminished ability of microsatellites to detect hybridisation compared to SNPs. Analyses of population structure confirm that at least four genetic clusters are present within Italian pike, and that anthropogenic translocations between geographically isolated basins have taken place. Moreover, I unveil genomic adaptations in Italian pike concerning olfactory perception, immune response and metabolism, emphasising the need to preserve the adaptive potential of endemic species. In marble trout, I filtered and validated in silico a set of more than 8 million high-quality SNPs after removing pseudo-SNPs from paralogous regions of the salmonid genome and potentially introgressed allochthonous alleles. Switching from current microsatellite-based screening to a SNP genotyping array would not only increase resolving power for hybrid detection but also produce faster results in a less invasive manner. Indeed, while current screening methods require up to a week during which time marble trout are confined in low density pools, genetic analyses with the proposed technology would reduce time of confinement by several days, resulting in lower stress levels and higher post-release survival rates in marble trout wild breeders. Findings from this study will greatly facilitate detection of genetic introgression from introduced European pike and brown trout into these Alpine endemics which will inform regional and national conservation practices.

description: We study the finite part of the sphere partition function of d-dimensional Conformal Field Theories (CFTs) as a function of exactly marginal couplings. In odd dimensions, this quantity is physical and independent of the exactly marginal couplings. In even dimensions, this object is generally regularization scheme dependent and thus unphysical. However, in the presence of additional symmetries, the partition function of even-dimensional CFTs can become physical. For two-dimensional N=(2,2) supersymmetric CFTs, the continuum partition function exists and computes the Kahler potential on the chiral and twisted chiral superconformal manifolds. We provide a new elementary proof of this result using Ward identities on the sphere. The Kahler transformation ambiguity is identified with a local term in the corresponding N=(2,2) supergravity theory. We derive an analogous, new, result in the case of four-dimensional N=2 supersymmetric CFTs: the S^4 partition function computes the Kahler potential on the superconformal manifold. Finally, we show that N=1 supersymmetry in four dimensions and N=(1,1) supersymmetry in two dimensions are not sufficient to make the corresponding sphere partition functions well-defined functions of the exactly marginal parameters.

Morphological and genetic diversification of Old-World marbled newts, with the description of a new and ‘not-at-all-cryptic’ subspecies from the Iberian Peninsula (Triturus, Salamandridae)

description: Morphological and genetic variation of organisms is generally lower in northern than in southern regions of the Palearctic. This ubiquitous geographical pattern has been associated with extinction and recolonization processes in the north versus persistence in the Mediterranean area, as governed by climate change in the Pleistocene. One area of differentiation and complexity is the Iberian Peninsula where two distinct sister-species of marbled newts possess adjoining and geographically sharply delimited ranges over the north (Triturus marmoratus) and the south of the peninsula (T. pygmaeus). Within the latter species two forms are here documented, with different colouration patterns and non-overlapping ranges. The southern form is striped, much as in T. marmoratus, and occurs to the south of the Guadalquivir River. The northern form, here described as a new subspecies, has a reticulated dorsal colouration. It occurs only north of the Guadalquivir and is thus sandwiched in between two striped marbled newt taxa. Both T. pygmaeus subspecies engage inside the Doñana National Park in a ca. 2,500 m narrow contact zone. Although an inferred substantial selection against hybrids goes a long way to support species status, a reanalysis of published genetic data is required to solve this issue, along with the wider investigation of the same type of (microsatelite) data for the southern, nominotypical subspecies.

description: Reprocessing of X-ray pulsar radiation by the atmosphere of a companion in a binary system may result in reflected pulse radiation with a period of the pulses equal to the period of the pulsar under suitable conditions. In this paper the influence of the rotation of the source - the pulsar - about its axis on the parameters of thus reflected pulses is investigated. The binary system is modeled by the spherical reflective screen and the compact source uniformly rotating about its axis; the beam pattern (BP) of the source periodically runs over the surface of the screen. Irradiation of the screen by the pulses infinitely narrow in time and by the rectangular pulses is considered. In this model parameters of the pulses reflected in some directions are calculated. The main conclusion provided by the consideration of this model is that the properties of reflected pulses - their profile, and the moments of reaching the observer - substantially depend on the correlation between the light speed and the speed of the BP passing over the companion surface. The possibility of applying of the obtained results to the known X-ray accretion-powered pulsars and rotation-powered pulsars in binary systems is examined.

description: Finely modelled ceramic Gnathia-ware cup. Named after the ancient city of Gnathia in Southern Italy (region of Apulia), Gnathian ware vessels were painted in a variety of colours and were characteristic of the late 4th century BCE pottery production in Southern Italy, although also extensively traded to the rest of the Mediterranean. This cup has a loop strap handle coming off the shoulder and rolling onto the lower rim, which flares outward at the top. The round body is incised with grooves while the rim bears, from top to bottom, floral, dotted, and geometric decoration in white and ochre, finished off in a high black gloss. As for similar examples, the base is set on a narrow, slightly raised foot, the lower part of which was originally painted black as the rest of the body and rim; there is a reserved band just below the belly. This specific type of cup is sometimes also referred to as a ‘thistle mug’, due to its resemblance to a thistle in shape. Production was probably centered around Taras, with workshops in Gnathia (present-day Egnazia) and Canosa. Object number: 127.006.

description: A recent numerical lattice calculation of the kaon mixing matrix elements of general $ΔS=2$ four-fermion operators using staggered fermions relied on two auxiliary theoretical calculations. Here we describe the methodology and present the results of these two calculations. The first concerns one-loop matching coefficients between staggered lattice operators and the corresponding continuum operators. Previous calculations with staggered fermions have used a non-standard regularization scheme for the continuum operators, and here we provide the additional matching factors needed to connect to the standard regularization scheme. This is the scheme in which two-loop anomalous dimensions are known. We also observe that all previous calculations of this operator matching using staggered fermions have overlooked one matching step in the continuum. This extra step turns out to have no impact on three of the five operators (including that relevant for $B_K$), but does affect the other two operators. The second auxiliary calculation concerns the two-loop renormalization group (RG) evolution equations for the $B$-parameters of the $ΔS=2$ operators. For one pair of operators, the standard analytic solution to the two-loop RG equations fails due to a spurious singularity introduced by the approximations made in the calculation. We give a non-singular expression derived using analytic continuation, and check the result using a numerical solution to the RG equations. We also describe the RG evolution for "golden" combinations of $B$-parameters, and give numerical results for RG evolution matrices needed in the companion lattice calculation.

Charge and spin current in a quasi-one-dimensional quantum wire with spin-orbit coupling

description: We show that Rashba spin-orbit coupling may result in an energy gap in the spectrum of electrons in a two-mode quantum wire if a suitable confining potential is chosen. This leads to a dip in the conductance and a spike in the spin current at the corresponding position of the Fermi level. Therefore one may control the charge and spin currents by means of electrostatic gates without using magnetic field or magnetic materials.

description: We present a family of solutions of Einstein's gravity minimally coupled to a complex, massive scalar field, describing asymptotically flat, spinning black holes with scalar hair and a regular horizon. These hairy black holes (HBHs) are supported by rotation and have no static limit. Besides mass M and angular momentum J, they carry a conserved, continuous Noether charge Q measuring the scalar hair. HBHs branch off from the Kerr metric at the threshold of the superradiant instability and reduce to spinning boson stars in the limit of vanishing horizon area. They overlap with Kerr black holes for a set of (M,J) values. A single Killing vector field preserves the solutions, tangent to the null geodesic generators of the event horizon. HBHs can exhibit sharp physical differences when compared to the Kerr solution, such as J/M^2>1, quadrupole moment larger than J^2/M and larger orbital angular velocity at the innermost stable circular orbit. Families of HBHs connected to the Kerr geometry should exist in scalar (and other) models with more general self interactions.
