description: We have searched for dust in an optical sample of 910 Early-Type Galaxies (ETG) in the Virgo cluster (447 of which are optically complete at m_pg <= 18.0), extending also to the dwarf ETG, using Herschel images at 100, 160, 250, 350 and 500 microns. Dust was found in 52 ETG (46 are in the optically complete sample), including M87 and another 3 ETG with strong synchrotron emisssion. Dust is detected in 17% of ellipticals, 41% of lenticulars, and in about 4% of dwarf ETG. The dust-to-stars mass ratio increases with decreasing optical luminosity, and for some dwarf ETG reaches values similar to those of the dusty late-type galaxies. Slowly rotating ETG are more likely to contain dust than fast rotating ones. Only 8 ETG have both dust and HI, while 39 have only dust and 8 have only HI, surprisingly showing that only rarely dust and HI survive together. ETG with dust appear to be concentrated in the densest regions of the cluster, while those with HI tend to be at the periphery. ETG with an X-ray active SMBH are more likely to have dust and vice versa the dusty ETG are more likely to have an active SMBH.

description: We propose a novel lattice calculation of spontaneous chiral symmetry breaking in QED model with 2+1 dimensional fermion brane. Considering the relativistic action with gauge symmetry we rigorously carry out path integral in Monte-Carlo simulation with Fermi-velocity relevant to effective coupling constant. We numerically show the evidence of spontaneous chiral symmetry breaking in strong coupling region with chiral condensate, low-lying mode distribution and Nambu-Goldstone boson spectrum in bare Fermi-velocty $v=0.1$. This is a feasible study to investigate the phase structure of Graphene.

description: We present an empirical determination of the white dwarf cooling sequence in the globular cluster 47 Tucanae. Using spectral models, we determine temperatures for 887 objects from Wide Field Camera 3 data, as well as 292 objects from data taken with the Advanced Camera for Surveys. We make the assumption that the rate of white dwarf formation in the cluster is constant. Stellar evolution models are then used to determine the rate at which objects are leaving the main sequence, which must be the same as the rate at which objects are arriving on the white dwarf sequence in our field. The result is an empirically derived relation between temperature ($T_{eff}$) and time ($t$) on the white dwarf cooling sequence. Comparing this result to theoretical cooling models, we find general agreement with the expected slopes between 20,000K and 30,000K and between 6,000K and 20,000K, but the transition to the Mestel cooling rate of $T_{eff} \propto t^{-0.4}$ is found to occur at hotter temperatures, and more abruptly than is predicted by any of these models.

description: THE 25TH YEAR is a collection that seeks to understand what it means to bear witness. Cataloging their environment is how the speaker reconciles their fraught reality, making sense of the disorder of living. This disorder is reflected in the form of the work, as most of the poems are in free verse, with occasional variation. The poems in this collection explore themes of memory, community, and ordinary human kindness – and meditate on how powerful the practice of witness can be. In the tradition of Baldwin, Baudelaire, and the flâneur, the speaker observes what can often be missed, in order to connect to their community and themselves.

description: Recent experiments demonstrated the generation of entanglement by quasiadiabatically driving through quantum phase transitions of a ferromagnetic spin-1 Bose-Einstein condensate in the presence of a tunable quadratic Zeeman shift. We analyze, in terms of the Fisher information, the interferometric value of the entanglement accessible by this approach. In addition to the Twin-Fock phase studied experimentally, we unveil a second regime, in the broken axisymmetry phase, which provides Heisenberg scaling of the quantum Fisher information and can be reached on shorter time scales. We identify optimal unitary transformations and an experimentally feasible optimal measurement prescription that maximize the interferometric sensitivity. We further ascertain that the Fisher information is robust with respect to nonadiabaticity and measurement noise. Finally, we show that the quasiadiabatic entanglement preparation schemes admit higher sensitivities than dynamical methods based on fast quenches.

description: Rocks exhumed from ancient subduction zone interfaces often contain both coherent terranes and block-in-matrix mélanges, but the relationship between these two endmembers and its implications for underplating have not been closely examined. The Catalina Schist is a Cretaceous paleosubduction complex on Santa Catalina Island (California) that contains an amphibolite facies mélange with an underlying unit of coherent amphibolite. In this thesis, I present a metamorphic history of the coherent amphibolite that is based on field and petrographic evidence and pressure-temperature estimates from Raman elastic barometry and trace element thermometry. Rocks from the coherent amphibolite record peak metamorphic conditions of 1.20 to 1.29 GPa and 665 to 691 °C. This is consistent with several amphibolite mélange blocks, but the range of block conditions suggests that some upwards movement of the coherent amphibolite may have occurred at the subduction interface prior to the current juxtaposition of the two units.

description: A semi-numerical method is used in order to locate the position and calculate the period of periodic orbits in a 3D composite bisymmetrical potential, in a number of resonant cases. The potential consists of a 3D harmonic oscillator and a Plummer sphere. The outcomes are compared with results found using the numerical integration of the equations of motion and the agreement is very good. This agreement strongly suggests, that semi-numerical methods can be used in order to obtain fast and reliable results regarding the position and period of the periodic orbits in 3D composite potentials with a harmonic oscillator part and different kinds of perturbations. Comparison with other methods of obtaining 3D periodic orbits is discussed.

description: Treatment of periprosthetic femur fractures after total hip arthroplasty remains a major challenge in orthopedic surgery. Recently, a novel surgical technique using intraprosthetic screw fixation has been suggested. The purpose of this study was to evaluate the influence of drilling the femoral hip stem on integrity and strength of the implant. The hypothesis was that intraprosthetic drilling and screw fixation would not cause the load limit of the prosthesis to be exceeded and that deformation would remain within the elastic limit. A sawbone model with a conventional straight hip stem was used and a Vancouver C periprosthetic fracture was created. The fracture was fixed with a nine-hole less invasive stabilization system plate with two screws drilled and inserted through the femoral hip stem. Three different finite element models were created using ANSYS software. The models increased in complexity including joint forces and stress risers from three different dimensions. A variation of drilling positions was analyzed. Due to the complexity of the physiological conditions in the human femur, the most complex finite element model provided the most realistic results. Overall, significant changes in the stresses to the prosthesis caused by the drilling procedure were observed. While the stresses at the site of the bore hole decreased, the load increased in the surrounding stem material. This effect is more pronounced and further the holes were apart, and it was found that increasing the number of holes could counteract this. The maximum load was still found to be in the area of the prosthesis neck. No stresses above the load limit of titanium alloy were detected. All deformations of the prosthesis stem remained in the elastic range. These results may indicate a potential role for intraprosthetic screw fixation in the future treatment of periprosthetic femur fractures. © Institution of Mechanical Engineers.

description: Entanglement-enhanced atom interferometry has the potential of surpassing the standard quantum limit and eventually reaching the ultimate Heisenberg bound. The experimental progress is, however, hindered by various technical noise sources, including the noise in the detection of the output quantum state. The influence of detection noise can be largely overcome by exploiting echo schemes, where the entanglement-generating interaction is repeated after the interferometer sequence. Here, we propose an echo protocol that uses two-axis countertwisting as the main nonlinear interaction. We demonstrate that the scheme is robust to detection noise and its performance is superior compared to the already demonstrated one-axis twisting echo scheme. In particular, the sensitivity maintains the Heisenberg scaling in the limit of a large particle number. Finally, we show that the protocol can be implemented with spinor Bose-Einstein condensates. Our results thus outline a realistic approach to mitigate the detection noise in quantum-enhanced interferometry.
Heavy and Light Monopoles in Magnetic Reversion in Artificial Spin Ice

Subjects: subject: Mesoscale and Nanoscale Physics (cond-mat.mes-hall)

description: This work makes a theoretical study of the dynamics of emergent elemental excitations in artificial spin ice systems with hexagonal geometry during the magnetic reversion of the system. The magnetic and physical parameters of the nanoislands that form the array are considered as variables in the study. The parameters considered are: the energy barrier for the inversion of each nanoisland, the magnetic moment of the nanomagnets and the possible disorder in the sample. Our results show that the reversion dynamic presents two distinct mechanisms of magnetic reversion, with different elemental excitations for each mechanism. The first mechanism presents a reversion with the appearance of magnetic monopoles that do not move in the samples (heavy monopoles) and the absence of Dirac chains. In the other mechanism elemental magnetic excitations (light monopoles) appear that move great distances in the sample, giving rise to extensive Dirac chains during the magnetic reversion.

description: We are interested in reflection symmetric (x → - x) evolution problems on the infinite line. In the systems which we have in mind, a trivial ground state loses stability and bifurcates into a temporally oscillating, spatial periodic pattern. A famous example of such a system is the Taylor-Couette problem in the case of strongly counter-rotating cylinders. In this paper, we consider a system of coupled Kuramoto-Shivashinsky equations as a model problem for such a system. We are interested in solutions which are slow modulations in time and in space of the bifurcating pattern. Multiple scaling analysis is used in the existing literature to derive mean-field coupled Ginzburg-Landau equations as approximation equations for the problem. The aim of this paper is to give exact estimates between the solutions of the coupled Kuramoto-Shivashinsky equations and the associated approximations.

description: For hyperbolic systems in one spatial dimension ∂tu + C∂xu = f(u), u(t, x) ∈ ℝd, we study sequences of oscillating solutions by their Young-measure limit, μ, and develop tools to study the evolution of μ directly from the Young measure, v, of the initial data. For d ≤ 2 we construct a flow mapping, St, such that μ(t) = St(v) is the unique Young-measure solution for initial value v. For d ≥ 3 we establish existence and uniqueness of Young measures that have product structure, that is the oscillations in direction of the Riemann invariants are independent. Counterexamples show that neither μ nor the marginal measures of the Riemann invariants are uniquely determined from v, except if a certain structural interaction condition for f is satisfied. We rely on ideas of transport theory and make use of the Wasserstein distance on the space of probability measures.

description: We explore the effects of active galactic nuclei (AGN) and star formation activity on the infrared (0.3-1000 microns) spectral energy distributions of luminous infrared galaxies from z = 0.5 to 4.0. We have compiled a large sample of 151 galaxies selected at 24 microns (S24 > 100 uJy) in the GOODS-N and ECDFS fields for which we have deep Spitzer IRS spectroscopy, allowing us to decompose the mid-IR spectrum into contributions from star formation and AGN activity. A significant portion (~25%) of our sample is dominated by an AGN in the mid-IR. Based on the mid-IR classification, we divide our full sample into four sub-samples: z~1 star-forming (SF) sources; z~2 SF sources; AGN with clear 9.7 micron silicate absorption; and AGN with featureless mid-IR spectra. From our large spectroscopic sample and wealth of multi-wavelength data, including deep Herschel imaging at 100, 160, 250, 350, and 500 microns, we use 95 galaxies with complete spectral coverage to create a composite spectral energy distribution (SED) for each sub-sample. We then fit a two-temperature component modified blackbody to the SEDs. We find that the IR SEDs have similar cold dust temperatures, regardless of the mid-IR power source, but display a marked difference in the warmer dust temperatures. We calculate the average effective temperature of the dust in each sub-sample and find a significant (~20 K) difference between the SF and AGN systems. We compare our composite SEDs to local templates and find that local templates do not accurately reproduce the mid-IR features and dust temperatures of our high redshift systems. High redshift IR luminous galaxies contain significantly more cool dust than their local counterparts. We find that a full suite of photometry spanning the IR peak is necessary to accurately account for the dominant dust temperature components in high redshift IR luminous galaxies.

The art of being spoken through: Ventriloquism as feminism after conceptualism
Creators: name: Mcmichael, Hazel
Publisher: name: Loughborough University
Year: 2023
Subjects: Other earth sciences not elsewhere classified

description: What does it matter who is speaking? Voice is a vital concern, strategy, and trope in twenty-first century feminist discourses, where it is inextricable from identity politics. Imperatives to “speak out” have increasingly been superseded by cautions to “speak as” rather than “speak for”. Ventriloquism has frequently been invoked by feminists as a dead metaphor to name and problematise practices of speaking for others. This thesis questions what ventriloquism can contribute to feminist practices and politics of identity, location, and voice. Ventriloquism is reanimated as a political practice that has throughout history been predominantly deployed by women figured as oracles, witches, and hysterics. These figures are brought into transhistorical dialogues with a heterogeneous set of contemporary ventriloquial practices in Billie Whitelaw’s performances and Company SJ’s site-specific installation of Samuel Beckett’s Not I, Theresa Hak Kyung Cha’s performance video Mouth to Mouth, Caroline Bergvall’s book and performance Drift, and Vanessa Place’s book and performance of rape jokes. Close readings of these case studies examine how recitational and transmedial approaches that emerged in art, performance, and writing after conceptualism are mobilised to speak and witness various voices and stories that have been culturally, legally, and/or violently silenced. These include hysterical and “contained” women and children in residential institutions of postcolonial Catholic Ireland, women of the Korean diaspora in the US and US military sex workers in Korea, Black African migrants crossing the Mediterranean Sea and queer citizens in Europe, and men who tell rape jokes on social media and feminists who “call out” and “cancel” them. Each chapter responds to the question of when and where it is strategic to speak as, for, with, and through other voices, bodies, and spaces.

It describes the design of a high flux discharge source of atoms and a robust laser system using a DBR diode coupled with a high power Yb doped fiber amplifier for manipulating the beam of metastable atoms. The atoms are trapped in a small quartz cell in an extreme high vacuum. The trapping design uses an additional laser (repumper) and allows the capture of a large number of metastable helium atoms (approximately 109) in a geometry favorable for loading a tight magnetostatic trap.

Die Veranstaltungen finden über das Konferenzsystem BigBlueButton statt. Den Kaffee und die Kekse, die es in der Universitätsbibliothek normalerweise gratis dazu gibt, müssen sich die Teilnehmerinnen und Teilnehmer vorübergehend selbst neben ihre Rechner stellen, was dem Interesse in keiner Weise Abbruch getan hat. Im Gegenteil: An den ersten beiden Coffee Lectures im digitalen Raum nahmen jeweils 80 Interessierte teil. Sie wählten sich von verschiedenen Orten in ganz Deutschland und der Welt (Österreich, Schweiz, Großbritannien, USA und Kasachstan) in die Veranstaltung ein. Die Coffee-Lecture-Themen des digitalen Onlinesemesters sind: 1. Ethische Grundsätze und Reflexionsprozesse. Forschungsethik 2. Planen und Strukturieren. Forschungsdatenspeicherung 3.

description: We study the influence of a boundary point contact voltage on Coulomb blockadelike oscillations of the conductance in mesoscopic quantum wires of strongly correlated electrons. Bethe ansatz techniques allow one to understand lattice boundary effects together with nonconformal many-body behavior for such systems. We predict a nonlinear dependence of the initial (coherent) shift on oscillations with boundary potentials. The results are obtained for both spinless and spin cases.

description: Due to remarkable advances in colloid synthesis techniques, systems of squares and cubes, once an academic abstraction for theorists and simulators, are nowadays an experimental reality. By means of a free minimization of the free-energy functional, we apply Fundamental Measure Theory to analyze the phase behavior of parallel hard squares and hard cubes. We compare our results with those obtained by the traditional approach based on the Gaussian parameterization, finding small deviations and good overall agreement between the two methods. For hard squares our predictions feature at intermediate packing fraction a smectic phase, which is however expected to be unstable due to thermal fluctuations. This implies that for hard squares the theory predicts either a vacancy-rich second-order transition or a vacancy-poor weakly first-order phase transition at higher density. In accordance with previous studies, a second-order transition with a high vacancy concentration is predicted for hard cubes.

Das Phänomen der Komplexität beschäftigt die linguistische Forschung bereits seit einiger Zeit, insbesondere die Begriffsbestimmung sowie die Operationalisierung des Begriffs. Das Ziel der Tagung war, „durch einen möglichst breiten Blick auf Detailfragen linguistischer Komplexität in ‚well-defined areas‘ eine Ausgangsbasis für übergreifende Diskussionen zu den Beziehungen zwischen Komplexitätsbefunden auf verschiedenen linguistischen Ebenen und unter verschiedenen Gesichtspunkten zu schaffen“ (Tagungsexposé M. Hennig). In insgesamt vierzehn Beiträgen beleuchteten die Vortragenden das Phänomen der linguistischen Komplexität aus unterschiedlichen Blickwinkeln. Mit Fragen der Begriffsbestimmung befassten sich explizit Fischer, Engelberg, Lobin, Warnke und Staffeldt. Die Möglichkeiten der Operationalisierung und der Anwendung wurden in allen Beiträgen angesprochen; fokussiert wurden dabei unterschiedliche linguistische Beschreibungsebenen sowie vielfältige Zusammenhänge mit anderen semiotischen Ressourcen.

description: In the present study we examined the trafficking pathways of connexin49 (Cx49) fused to green fluorescent protein (GFP) in polar and non-polar cell lines. The Cx49 gene was isolated from ovine lens by RT-PCR. Cx49 cDNA was fused to GFP and the hybrid cDNA was transfected into several cell lines. After transfection of Cx49-GFP cDNA into HeLa cells, it was shown using the double whole-cell patch-clamp technique that the expressed fusion protein was still able to form conducting gap junction channels. Synthesis, assembly, and turnover of the Cx49-GFP hybrid protein were investigated using a pulse-chase protocol. A major 78-kDa protein band corresponding to Cx49-GFP could be detected with a turnover of 16-20 h and a half-life time of 10 h. The trafficking pathways of Cx49-GFP were monitored by confocal laser microscopy. Fusion proteins were localized in subcellular compartments, including the endoplasmic reticulum (ER), the ER-Golgi intermediate compartment, the Golgi apparatus, and the trans-Golgi network, as well as vesicles traveling towards the plasma membrane. Time-dependent sequential localization of Cx49-GFP in the ER and then the Golgi apparatus supports the notion of a slow turnover of Cx49-GFP compared to other connexins analyzed so far. Gap junction plaques resembling the usual punctuate distribution pattern could be demonstrated for COS-1 and MDCK cells. Basolateral distribution of Cx49-GFP was observed in polar MDCK cells, indicating specific sorting behavior of Cx49 in polarized cells. Together, this report describes the first characterization of biosynthesis and trafficking of lens Cx49.

description: Kontrolliertes Einfrieren in den Temperaturbereich zwischen – 80 °C und – 196 °C erlaubt es Zellen, bei gleichzeitigem Erhalt ihrer Vitalität nach dem Auftauprozess, langfristig zu lagern. Durch die Verwendung von Antioxidantien sollte in der vorliegenden Arbeit eine Steigerung der Rekultivierbarkeit von mesenchymalen Stammzellen nach der Kryokonservierung erzielt werden. Der Zusatz von 100 μM α–Tocopherol steigerte die Rekultivierungseffzienz der Stammzellen um 117,5 % gegenüber der Kontrolle ohne Antioxidans. Darüber hinaus konnte gezeigt werden, dass eine Reduzierung der DMSO-Konzentration möglich ist, da Versuche mit 200 μM α–Tocopherol und 2,5 % bzw. 5 % DMSO vergleichbare Resultate von ca. 164 % bzw. 170 % Rekultivierbarkeit erzielten.
A Semi-Social Magazine: Love, Life, and Architectural Design

Publisher: name: Histories of Postwar Architecture

description: This paper analyses the magazine Architectural Design (AD) under the post-war editorship of Monica Pidgeon. Through extensive archival research, content analysis, oral histories, and interviews, I adopt a unique biographical approach to understand the people behind the magazine and their networks, and argue that Pidgeon had a very different idea of criticism to how we might today interpret it in retrospect. Pidgeon was neither an architect nor an ideologue and did not run her magazine on the basis of a campaign for how she believed the world should be reconstructed. Instead, her commitment was primarily to people – the architects whom she accepted into her network – rather than their buildings. I argue that Pidgeon’s personal and professional life became so entangled that she developed this network as a type of social ‘club’ to the extent that AD turned into her life and her life into AD. The paper is split into two halves: the first explores Pidgeon’s background in order to develop an understanding of her approach to editing an architectural magazine; the second describes the contents of the magazine and the networks of its contributors during the tenure of the first three Technical Editors, Theo Crosby, Kenneth Frampton, and Robin Middleton. In contrast to conventional understandings of architectural criticism and history, the paper emphasises the messy personal, human, back-stories as a fundamental driver of the decisions that are made about what is ‘given ink’ and, as a consequence, what is ultimately nominated to the canon of architectural history.

description: Charged-current single pion production in scattering off 12C is investigated for neutrino energies up to 1 GeV. An impact of nuclear effects with in-medium modifications of the Delta(1232) resonance properties as well as an effective field theory nonresonant background contribution are discussed. Dependence of the fraction of Delta(1232) decays into npnh states on incident neutrino energy is estimated. A model of Nieves et al. [1] is further developed by performing exact integration avoiding several approximations. The effect of exact integration is investigated both for double-differential and total neutrino-nucleus cross sections.
Italy, 1980s: Touring Club Italiano’s Guides and the Non-monumental Heritage

description: Between 1983 and 1985, the T.C.I. (Touring Club Italiano) published the three hardcover, large size volumes of the collection Città da scoprire. Guida ai centri minori, literally Cities to be discovered. A guide to Italy’s secondary towns, directed by historian and geographer Lucio Gambi. The guide label is misleading for such an ambitious editorial project. A notable series of long form essays by prominent scholars reconstruct the architectural and urban development of each of the more than 200 selected Italian towns. All texts are accompanied by a rich iconography, also featuring specifically commissioned aerial views, and cartography, including diagrams detailing the main phases and events of the agglomeration’s growth. The Guida ai centri minori seamlessly fitted into the T.C.I.’s cultural agenda of the time, aimed at rerouting mass tourism away from its traditional destinations. As a matter of fact, the three books reached a wide, lay public, as they were delivered as Christmas gifts to hundreds of thousands of the association’s members. They were more than a practical tool for tourists, though. The focus on the centri minori was the occasion to shape an innovative, comprehensive representation of a non-monumental Italy, one which could replace the outdated stereotypes of the Bel Paese. Moreover, thanks to its one-of-a-kind positioning between scholarly research and dissemination, the Guida ai centri minori acted as a powerful tool to mainstreaming this up-to-date representation. Starting from this case study, this paper aims at outlining the 1980s T.C.I.’s cultural project for the dissemination to a larger audience of the latest advancements of the high-culture debate on Italy’s non-monumental heritage.

The New Brutalism: Ethic vs. Marxism? Ideological Collisions in Post-War English Architecture
Creators: name: Groaz, Silvia
Publisher: name: Histories of Postwar Architecture
Year: 2021

description: At the end of the Second World War, an intense ideological confrontation took place in England, where the principles of reconstruction were established around the ‘low rise’ and ‘high rise’ dichotomy. The debate was influenced by a politicized generational divide, pitting the legacy of Howard’s Garden City model, supported by those who called themselves ‘Marxists’, against Le Corbusier’s Unité at Marseille, defended by a younger generation of architects who took a ‘non-Marxist’ position. The various political tendencies were translated into stylistic rules that addressed types, city configuration, and even materials, according to a rich constellation of new labels: the New Humanism derived from Soviet Social Realism, the William Morris Revival and People’s Detailing, the New Picturesque advocated as a democratic model by Nikolaus Pevsner, and the New Empiricism reworked by Eric de Maré on the Cooperative Housing Schemes of the Swedish welfare state. It is in this context that the New Brutalism originated. The term disguised subversive attributes with respect to the relationship of urban and architectural models with political demands. The rigid ideological instances that configured a conventional model for the reconstruction were purged in the New Brutalism through the introduction of a category that supplanted Marxist ideology. Ethics, translated into the truth to materials and structure, as well as into the concept of ‘as found’, paved its way through an argument rooted in the architectural discourse.

description: Context. The QUBIC collaboration is building a bolometric interferometer dedicated to the detection of B-mode polarization fluctuations in the Cosmic Microwave Background. Aims. We introduce a self-calibration procedure related to those used in radio-interferometry to control a large range of instrumental systematic errors in polarization-sensitive instruments. Methods. This procedure takes advantage of the fact that in the absence of systematic effects, measurements on redundant baselines should exactly match each other. For a given systematic error model, measuring each baseline independently therefore allows to write a system of nonlinear equations whose unknowns are the systematic error model parameters (gains and couplings of Jones matrices for instance). Results. We give the mathematical basis of the self-calibration. We implement this method numerically in the context of bolometric interferometry. We show that, for large enough arrays of horns, the nonlinear system can be solved numerically using a standard nonlinear least-squares fitting and that the accuracy achievable on systematic effects is only limited by the time spent on the calibration mode for each baseline apart from the validity of the systematic error model.
