description: The radio galaxy Cen A has been detected all the way up to the TeV energy range. This raises the question about the dominant emission mechanisms in the high-energy domain. Spectral analysis allows us to put constraints on the possible emission processes. Here we study the hard X-ray emission as measured by INTEGRAL in the 3-1000 keV energy range, in order to distinguish between a thermal and non-thermal inverse Compton process. The hard X-ray spectrum of Cen A shows a significant cut-off at energies Ec = 434 (+106 -73) keV with an underlying power law of photon index 1.73 +- 0.02. A more physical model of thermal Comptonisation (compPS) gives a plasma temperature of kT = 206+-62 keV within the optically thin corona with Compton parameter y = 0.42 (+0.09 -0.06). The reflection component is significant at the 1.9 sigma level with R = 0.12 (+0.09 -0.10), and a reflection strength R>0.3 can be excluded on a 3 sigma level. Time resolved spectral studies show that the flux, absorption, and spectral slope varied in the range f(3-30 keV) = (1.2 - 9.2)e-10 erg/cm**2/s, NH = (7 - 16)e22 1/cm**2, and photon index 1.75 - 1.87. Extending the cut-off power law or the Comptonisation model to the gamma-ray range shows that they cannot account for the high-energy emission. On the other hand, also a broken or curved power law model can represent the data, therefore a non-thermal origin of the X-ray to GeV emission cannot be ruled out. The analysis of the SPI data provides no sign of significant emission from the radio lobes and gives a 3 sigma upper limit of f(40-1000 keV) < 0.0011 ph/cm**2/s. While gamma-rays, as detected by CGRO and Fermi, are caused by non-thermal (jet) processes, the main process in the hard X-ray emission of Cen A is still not unambiguously determined, being either dominated by thermal inverse Compton emission, or by non-thermal emission from the base of the jet.

description: In the present paper we study the scalar sector of the quasinormal modes of charged general relativistic, static and spherically symmetric black holes coupled to nonlinear electrodynamics and embedded in a class of scalar-tensor theories. We find that for certain domain of the parametric space there exist unstable quasinormal modes. The presence of instabilities implies the existence of scalar-tensor black holes with primary hair that bifurcate from the embedded general relativistic black-hole solutions at critical values of the parameters corresponding to the static zero-modes. We prove that such scalar-tensor black holes really exist by solving the full system of scalar-tensor field equations for the static, spherically symmetric case. The obtained solutions for the hairy black holes are non-unique and they are in one to one correspondence with the bounded states of the potential governing the linear perturbations of the scalar field. The stability of the non-unique hairy black holes is also examined and we find that the solutions for which the scalar field has zeros are unstable against radial perturbations. The paper ends with a discussion on possible formulations of a new classification conjecture.

description: Mutually unbiased bases for quantum degrees of freedom are central to all theoretical investigations and practical exploitations of complementary properties. Much is known about mutually unbiased bases, but there are also a fair number of important questions that have not been answered in full as yet. In particular, one can find maximal sets of ${N+1}$ mutually unbiased bases in Hilbert spaces of prime-power dimension ${N=p^\m}$, with $p$ prime and $\m$ a positive integer, and there is a continuum of mutually unbiased bases for a continuous degree of freedom, such as motion along a line. But not a single example of a maximal set is known if the dimension is another composite number ($N=6,10,12,...$). In this review, we present a unified approach in which the basis states are labeled by numbers ${0,1,2,...,N-1}$ that are both elements of a Galois field and ordinary integers. This dual nature permits a compact systematic construction of maximal sets of mutually unbiased bases when they are known to exist but throws no light on the open existence problem in other cases. We show how to use the thus constructed mutually unbiased bases in quantum-informatics applications, including dense coding, teleportation, entanglement swapping, covariant cloning, and state tomography, all of which rely on an explicit set of maximally entangled states (generalizations of the familiar two--q-bit Bell states) that are related to the mutually unbiased bases. There is a link to the mathematics of finite affine planes. We also exploit the one-to-one correspondence between unbiased bases and the complex Hadamard matrices that turn the bases into each other. The ultimate hope, not yet fulfilled, is that open questions about mutually unbiased bases can be related to open questions about Hadamard matrices or affine planes, in particular the ...[rest deleted]

Entre la arcilla y la madera. Reflexiones sobre la pervivencia de formas cerámicas romanas en la tornería tradicional asturiana

description: La vajilla de las casas campesinas asturianas entre el siglo XVI y el XIX era, casi en su totalidad, de madera torneada. Los cuencos y las fuentes de la tornería tradicional asturiana, sobre todo los fabricados en la zona de Ibias recuerdan y tienen una gran familiaridad con algunas formas de cerámica romana que se documentan en Asturias entre los siglos I y II d.C.. Pero… ¿a qué se debe éste hecho? Tomando como punto de partida el trabajo del Catedrático de Prehistoria de la Universidad de Oviedo, D. Miguel Ángel de Blas Cortina, en el que señala un posible origen romano para ciertas formas en las vasijas de madera de la tornería tradicional de Asturias. Aportaremos nuevos ejemplos que abalan esta tesis apoyados en los avances de los estudios arqueológicos sobre cerámica y ajuar doméstico romano, que se han obtenido en las últimas décadas. Así veremos cómo este tipo de menaje en madera de los siglos XVI al XIX, del que seguro que existió un precedente en época medieval, tiene grandes similitudes con diversas tipologías de Terra Sigillatta y con cerámicas comunes romanas. Una pervivencia de milenios, que se mantuvo hasta hace poco a través de una serie de centros productores, localizados principalmente en el occidente asturiano. Los investigadores apuntan que el menaje fabricado en madera debía de ser algo muy común en la Asturias prerromana y romana, aunque lamentablemente no sea posible rastrear este tipo de cuencos a través del registro material. Aun así, todo indica que en esta región del occidente de la península ibérica se han mantenido muchas de esas formas hasta el siglo XIX. Gracias a los avances en el conocimiento de las producciones cerámicas romanas, tanto de Terra Sigillatta como de cerámica común, encontradas en diferentes yacimientos asturianos podemos presentar nuevas semejanzas y nuevas influencias, que nos señalarán las grandes similitudes con las producciones de la tornería tradicional. Conociendo así la herencia romana en las tradiciones del norte peninsular a través de unos ejemplos muy particulares, hasta cierto punto muy poco conocidos y que casi han llegado hasta nosotros.
Deconfinement in Yang-Mills theory through toroidal compactification with deformation

description: We introduce field theory techniques through which the deconfinement transition of four-dimensional Yang-Mills theory can be moved to a semi-classical domain where it becomes calculable using two-dimensional field theory. We achieve this through a double- trace deformation of toroidally compactified Yang-Mills theory on R2 \times S1_L \times S1_β. At large N, fixed-L, and arbitrary β, the thermodynamics of the deformed theory is equivalent to that of ordinary Yang-Mills theory at leading order in the large N expansion. At fixed-N, small L and a range of β, the deformed theory maps to a two-dimensional theory with electric and magnetic (order and disorder) perturbations, analogs of which appear in planar spin-systems and statistical physics. We show that in this regime the deconfinement transition is driven by the competition between electric and magnetic perturbations in this two-dimensional theory. This appears to support the scenario proposed by Liao and Shuryak regarding the magnetic component of the quark-gluon plasma at RHIC.

Estimating the Production Rate of Loosely-bound Hadronic Molecules using Event Generators
Creators: name: Artoisenet, Pierre
name: Braaten, Eric
Publisher: name: arXiv
Year: 2010
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: We examine the use of hadronic event generators, such as Pythia or Herwig, to estimate the production rate of loosely-bound hadronic molecules, such as the deuteron and the X(3872). In the case of the deuteron, we point out that there are large uncertainties in the normalization of the predictions using event generators, because baryon pair distributions are not among the inputs used to tune the event generators. Predictions using Pythia for anti-deuteron production in Upsilon decay are compared to measurements by the CLEO Collaboration. They suggest that Pythia overpredicts the probability of producing pairs of baryons, at least in Upsilon decay into three gluons, and that the standard value of the coalescence parameter underpredicts the probability for formation of a deuteron from a neutron and proton with small relative momentum. In the case of the X(3872), we discuss a proposed upper bound on the prompt cross section at the Tevatron that has been used as an argument against the X(3872) being a loosely-bound charm meson molecule. We demonstrate that this proposed upper bound is invalid by showing that the analogous upper bound for the anti-deuteron would be smaller than the observed anti-deuteron cross section.

Herakles at the ends of the Earth
Creators: name: Evans, Hampton
Publisher: name: University of British Columbia
Year: 2022

description: The hero-god Herakles was worshipped across the Mediterranean by the Greeks, from Spain in the west to Bactria in the east. The goal of this paper is to examine one specific facet and use of this figure, how he was utilized in order to justify appropriation of land and territory by the Greeks and legitimize their rule over non-Greek peoples. First, the wildly different versions of Herakles seen in several early sources, including Homer and Hesiod, are examined and discussed. Next, three case studies are examined in order to see how different groups of Greeks utilized and rewrote the story of Herakles to make irridentist claims to territory. The case studies are Sicily, focusing on the sites of Akragas and Agyrium, as well as the account of Diodoros of Sicily; Macedon, focusing first on how the Macedonian kings prior to Alexander used Herakles to claim Greek identity and justify their growing power, before turning to how Alexander himself utilized Herakles to justify his epoch-defining conquest of the Persian Empire and his rule over non-Greeks; and Bactria, focusing especially on the king Demetrios I and how he invoked Herakles and Alexander to justify his rule, building on centuries of narratives to secure their power at this far edge of the Greek world. Finally, the conclusions drawn from these case studies are summarized and tied together to see how Herakles was used to legitimize these claims and the relevance of this study for understanding both the ancient world and its utility for the modern one.

description: We describe ground states of correlated electron systems in which the electron fractionalizes into separate quasiparticles which carry its spin and its charge, and into real Majorana fermions which carry its Fermi statistics. Such parent states provide a unified theory of previously studied fractionalized states: their descendants include insulating and conducting states with neutral spin S=1/2 fermionic spinons, and states with spinless fermionic charge carriers. We illustrate these ideas on the honeycomb lattice, with field theories of such states and their phase transitions.

Late Roman pottery standardization: H85's case study

Year: 2016

description: The aim of this paper is to determine the degree of standardization of some late Roman pottery productions. We selected a form well represented in the ceramic contexts identified in the excavations of the Late Antique port-canal of Classe, the Hayes 85 cup. The discovery of a significant number of fragments and whole pieces of these forms at the port of Classe provided us with a high number of cases which allowed for statistical analyses and obtaining conclusive data. This cup is a form which is considered rare in Hayes’ monumental book, and only new discoveries of the last 10 years show us how much we still have to understand about the characteristics of late Roman production, trade and distribution. With this in mind, we used a new statistical system which analyses the main changes in the profile of this type and its variants.

description: The interfacial screening charge that arises to compensate electric fields of dielectric or ferroelectric thin films is now recognized as the most important factor in determining the capacitance or polarization of ultrathin ferroelectrics. Here we investigate using aberration-corrected electron microscopy and density functional theory how interfaces cope with the need to terminate ferroelectric polarization. In one case, we show evidence for ionic screening, which has been predicted by theory but never observed. For a ferroelectric film on an insulating substrate, we found that compensation can be mediated by interfacial charge generated, for example, by oxygen vacancies.

Thesis - Optimization of Steelmaking processes in an EAF
Creators: name: Busa, Neel Hemal
Publisher: name: Purdue University Graduate School
Year: 2023
Subjects: Numerical modelling and mechanical characterisation

description: The Electric Arc Furnace is being used quite frequently and significantly in today’s environment due to its energy saving and improved product quality features. It is even more important to study more about optimizing the processes involved in the EAF in order to capitalize on its positive features and thus able to contribute to the world in our bid to fight global climate change. During the refining stage of the Electric Arc Furnace (EAF) operation, molten steel is stirred to facilitate steel/slag reactions and the removal of impurities, which determines the quality of the steel . The stirring process is driven by the injection of oxygen, which is carried out by burners operating in lance mode. In this study, a computational platform is used to analyze the flow dynamics produced during the stirring of the steel bath in an industry-scale EAF. Namely, non-reacting, three-dimensional, transient simulations of the liquid bath stirred by oxygen injection are carried out to analyze the mixing process. The CFD domain includes the liquid bath and the oxygen injected by three coherent jets. The study includes a baseline case, where the oxygen is injected at 1000 SCFM in all the burners. Two sets of cases are also included: first set considers cases where oxygen is injected at a reduced and at an increased uniform flow rate: 750 and 1250 SCFM, respectively. Second set considers cases with non-uniform injection rates in each burner, which keep the same total flow rate of the baseline case, 3000 SCFM. The analysis is also quantified by defining two variables: the mixing time and the standard deviation of the flow velocity. Results indicate that the mixing rate of the bath is determined by flow dynamics near the injection cavities, and that the formation of very low velocity regions or ‘dead zones’ at the center of the furnace and at the balcony regions prevent the flow mixing. All the non-uniform injection cases reduce the mixing time obtained in the baseline case. The melting of HBI/scrap in an electric arc furnace (EAF) is studied by using a computational fluid dynamics (CFD) platform. A previously developed scrap melting model is extended to investigate the different physical phenomena involved in melting of HBI/scrap charges. The CFD platform merges three computational models, namely a scrap/HBI melting model, an electric arc model and a coherent jet model. The simulation conditions were selected to match those typically seen in industry-scale EAFs.
Are GRU Cells More Specific and LSTM Cells More Sensitive in Motive Classification of Text?

description: In the Thematic Apperception Test, a picture story exercise (TAT/PSE; Heckhausen, 1963), it is assumed that unconscious motives can be detected in the text someone is telling about pictures shown in the test. Therefore, this text is classified by trained experts regarding evaluation rules. We tried to automate this coding and used a recurrent neuronal network (RNN) because of the sequential input data. There are two different cell types to improve recurrent neural networks regarding long-term dependencies in sequential input data: long-short-term-memory cells (LSTMs) and gated-recurrent units (GRUs). Some results indicate that GRUs can outperform LSTMs; others show the opposite. So the question remains when to use GRU or LSTM cells. The results show (N = 18000 data, 10-fold cross-validated) that the GRUs outperform LSTMs (accuracy = .85 vs. .82) for overall motive coding. Further analysis showed that GRUs have higher specificity (true negative rate) and learn better less prevalent content. LSTMs have higher sensitivity (true positive rate) and learn better high prevalent content. A closer look at a picture x category matrix reveals that LSTMs outperform GRUs only where deep context understanding is important. As these both techniques do not clearly present a major advantage over one another in the domain investigated here, an interesting topic for future work is to develop a method that combines their strengths.

description: Introducing spin-polarized carriers in semiconductor lasers reveals an alternative path to realize room-temperature spintronic applications, beyond the usual magnetoresistive effects. Through carrier recombination, the angular momentum of the spin-polarized carriers is transferred to photons, thus leading to the circularly polarized emitted light. The intuition for the operation of such spin-lasers can be obtained from simple bucket and harmonic oscillator models, elucidating their steady-state and dynamic response, respectively. These lasers extend the functionalities of spintronic devices and exceed the performance of conventional (spin-unpolarized) lasers, including an order of magnitude faster modulation frequency. Surprisingly, this ultrafast operation relies on a short carrier spin relaxation time and a large anisotropy of the refractive index, both viewed as detrimental in spintronics and conventional lasers. Spin-lasers provide a platform to test novel concepts in spin devices and offer progress connected to the advances in more traditional areas of spintronics.

description: We question the use of triangle diagrams in the broken phase of the Standard Model Effective Field Theory (SMEFT) to derive sum-rules on certain dimension-six coefficients, as recently put forward by Cata, Kilian and Kreher in Ref. [arXiv:2011.09976]. Indeed, the aforementioned sum-rules are violated at tree level in simple consistent BSM scenarios. The underlying reason is that gauge-invariant combinations of Goldstone bosons and massive gauge fields are allowed to couple to matter currents which are not conserved. We show this in a toy model by computing the relevant triangle diagrams, as well as by working out Wess--Zumino terms in the bosonic EFT below all fermion masses. The same approach applies also to the Standard Model and it provides a convenient and unusual way to check that the SM is anomaly free. We then apply similar techniques to the SMEFT in presence of various dimension-6 operators.

description: External fields are a powerful tool to probe optical excitations in a material. The linear energy shift of an excitation in a magnetic field is quantified by its effective g factor. Here we show how exciton g factors and their sign can be determined by converged first-principles calculations. We apply the method to monolayer excitons in semiconducting transition metal dichalcogenides and to interlayer excitons in MoSe2/WSe2 heterobilayers and obtain good agreement with recent experimental data. The precision of our method allows us to assign measured g factors of optical peaks to specific transitions in the band structure and also to specific regions of the samples. This revealed the nature of various, previously measured interlayer exciton peaks. We further show that, due to specific optical selection rules, g factors in van der Waals heterostructures are strongly spin and stacking-dependent. The calculation of orbital angular momenta requires the summation over hundreds of bands, indicating that for the considered two-dimensional materials the basis set size is a critical numerical issue. The presented approach can potentially be applied to a wide variety of semiconductors.

description: В статье выявлены термины, концепции и интерпретации, которые формируют научный дискурс, связанный с исследованием такого феномена системы международных отношений как «цветные революции». Особым примером в статье выступают события на Украине 2004 г. Автор приходит к выводу, что зарубежные научные исследования сформировали такие трактовки цветных революций как ненасильственное сопротивление, демократизация и электоральная революция. Однако в настоящий момент в зарубежной науке о цветных революциях наблюдается волна ревизионизма, которая предлагает новые интерпретации украинских событий и последствий смены режима. Более того, события в Ливии, Сирии и Венесуэле также оказывают влияние на научные дискуссии в силу наличия насильственного компонента в виде гибридной и гражданской войн, а также гуманитарной катастрофы как последствий протестных движений. В российском научном направлении выявлены такие дискурсы как мягкая сила, внешнее вмешательство и демонтаж государственной системы. Российские ученые делают акцент на негативных последствиях политических трансформаций, связанных с искусственной сменой политических режимов. Кроме этого, российские исследователи подробно останавливаются на вопросе о противодействии России распространению цветных революций. Точкой соприкосновения зарубежного и российского направлений по изучению темы о цветных революциях выступает вопрос о том, как политические трансформации в одной стране оказывают влияние на изменения политики других государств по сдерживанию цветных революций. Научный дискурс смещается к изучению действий реципиентов политических трансформаций.
Exploring the relationship between parity and cardiovascular risk in older females with mild cognitive impairment

Publisher: name: University of British Columbia

description: As the population of older adults is expected to rise exponentially, the necessity for a clearer understanding of the components that contribute to age-related changes in cognitive function cannot be overstated. It is critical to understand the risk factors for cognitive decline and dementia in order to improve early detection and prevention. Females are disproportionately affected by Alzheimer’s Disease and other dementias due to contributing factors such as age and sex hormones. Pregnancy is a significant hormonal event in a female’s life and has been found to be associated with increased cardiovascular risk. While the relationship between pregnancy and cardiovascular risk in later life is well-established, whether the number of pregnancies influences this risk still requires further exploration. In this cross-sectional study, the differences in cardiovascular risk as well as executive function among levels of parity in older females with mild cognitive impairment were assessed. Further, the influence physical fitness has on the relationships between parity and cardiovascular risk as well as parity and executive function in older females with mild cognitive impairment was explored. Baseline data were compiled from two ongoing randomized controlled trials within the Aging, Mobility, and Cognitive Health Lab. Results showed that cardiovascular risk was lowest among primiparous females compared with multiparous females and yet, executive function was lowest among primiparous females and highest among females having given birth twice. In addition, physical fitness did not moderate the relationship between cardiovascular risk and parity nor did it moderate the relationship between parity and executive function. The findings from this highlight the importance of taking reproductive health into consideration when evaluating cardiovascular and cognitive health in females in later life.

description: New instruments and software are producing radical changes in the way in which archaeologists can gather information and create a site record. Photogrammetries are part of these new techniques that provide very accurate records. That is why these tools were applied during recent excavations carried out in the Neolithic tomb of Campa San Juan (Salas, Asturias). This archaeological site was dug for the first time last summer as part of a research project funded by the Valdés-Salas foundation. All the data recovered will allow us to develop several research lines which will enable a deeper understanding of the prehistoric structure.
 Regarding photogrammetries, a group of photos were taken during excavations with the goal of developing 3D models with Agisoft Photosocan software. As a consequence, eleven models were created along this year. These models constitute a parallel record of the excavation, providing very precise shortcuts to data. In this way, sections, measures and other information that have always disappeared after diggings, remain available.

description: Украинский кризис стал самым серьезным и опасным вызовом для европейской безопасности после распада Советского Союза и Югославии, а также серии этнополитических конфликтов на Балканах и в постсоветских республиках. Это событие соединило в себе наиболее масштабное противостояние России и Запада с момента окончания «холодной войны», российско-украинские противоречия из-за Крыма и юго-восточных областей Украины, а также трансформацию украинского государственного проекта в сторону формирования более жесткого контура национальной идентичности. Вокруг Украины столкнулись интересы России, Евросоюза и США, что обусловило выход этого, по сути, внутригосударственного кризиса на региональный и глобальный уровень. Все эти события заставили многих политиков и экспертов рассматривать процессы, происходящие на пространстве бывшего СССР сквозь украинскую призму, как ранее в 2006-2008 гг. они виделись в привязке к «казусу Косово». Настоящая статья посвящена рассмотрению того влияния, которое оказывала (и продолжают оказывать) политическая динамика вокруг Украины на другие постсоветские конфликты (приднестровский, грузино-абхазский, грузино-осетинский и нагорно-карабахский). Рассматривается прямое и косвенное воздействие украинского фактора на этнополитические противостояния на территории бывшего Советского Союза, дается дифференциация символического, идеологического и военно-политического влияния Киева на ситуацию в Приднестровье и на Кавказе. Автор особое внимание уделяет подходам России, показывая отсутствие универсализма в действиях Москвы на постсоветском пространстве. Он также анализирует позиции, как различных конфликтующих сторон, так и мотивацию акторов, вовлеченных в процессы мирного урегулирования.

description: Heavy elements, those produced by neutron-capture reactions, have traditionally shown no star-to-star dispersion in all but a handful of metal-poor globular clusters (GCs). Recent detections of low [Pb/Eu] ratios or upper limits in several metal-poor GCs indicate that the heavy elements in these GCs were produced exclusively by an r-process. Reexamining GC heavy element abundances from the literature, we find unmistakable correlations between the [La/Fe] and [Eu/Fe] ratios in 4 metal-poor GCs (M5, M15, M92, and NGC 3201), only 2 of which were known previously. This indicates that the total r-process abundances vary star-to-star (by factors of 2-6) relative to Fe within each GC. We also identify potential dispersion in two other GCs (M3 and M13). Several GCs (M12, M80, and NGC 6752) show no evidence of r-process dispersion. The r-process dispersion is not correlated with the well-known light element dispersion, indicating it was present in the gas throughout the duration of star formation. The observations available at present suggest that star-to-star r-process dispersion within metal-poor GCs may be a common but not ubiquitous phenomenon that is neither predicted by nor accounted for in current models of GC formation and evolution.
