 Ceit-IK4 lidera un proyecto que permitirá fabricar con polvos metálicos la carcasa de la turbina del avión
 01/04/2019
 La innovación que están desarrollando los investigadores de Ceit-IK4 consiste en utilizar el prensado isostático en caliente de polvo Astroloy (super-aleación base níquel) para fabricar la carcasa de la turbina del motor de nueva generación Ultrafan para la empresa Rolls Royce. Unos motores que alcanzan temperaturas muy altas y requieren a su alrededor de materiales que las soporten sin ningún tipo de alteración.
 El proyecto HUC, encuadrado en el programa europeo CleanSky2, pretende abordar los retos tecnológicos que han surgido a la hora de garantizar la inalterabilidad de la carcasa: acertar con la microestructura del polvo o material con que se fabricará la misma, lograr un polvo metálico de costo asumible y una buena calidad para el mecanizado. El proyecto culminará con la fabricación de carcasas y su ensayo en motores reales. https://www.izaro.com/ceit-ik4-lidera-un-proyecto-que-permitira-fabricar-con-polvos-metalicos-la-carcasa-de-la-turbina-del-avion/c-1553941214/ 1/1

description: Through Earth history, atmospheric oxygen has increased from initial values near zero to its present day level of about 21 % by volume; concomitantly, changes in ocean redox conditions have fundamentally altered global biogeochemical cycles. While there is a reasonable understanding of where oxygen history begins and ends, the quantitative timetable of oxygenation that links the endpoints has proven contentious. Equilibrium between marine surface environments and the overlying atmosphere suggests that carbonate-based redox proxies could refine palaeoredox records in time and space. Here we explore the use of Zn/Fe ratios to infer the evolution of atmospheric O2 through time, based on marine carbonate rocks that are well characterised in terms of depositional age, environmental setting, and diagenetic history. While Fe and Zn in the shallow ocean are mainly sourced from hydrothermal inputs, their redox sensitivities differ significantly, so that geological intervals with higher O2 would be characterised by stepped increases in Zn/Fe as preserved in shallow marine carbonates. Therefore, Zn/Fe analyses of ancient carbonates allow us to constrain past atmospheric pO2 levels, providing a secular record of atmospheric O2 over the past 3.5 billion years. In particular, we corroborate an earlier proposal that for much of the Proterozoic Eon, O2 levels were as low as 0.1-1 % of present atmospheric level. We conclude that Zn/Fe in shallow marine carbonate rocks has potential to provide a quantitative tracer for the long-term redox evolution of the oceans and the rise of atmospheric O2

description: Studies on human decision-making focused on humanitarian aid have found that cognitive biases can hinder the fair allocation of resources. However, few HCI and Information Visualization studies have explored ways to overcome those cognitive biases. This work investigates whether the design of interactive resource allocation tools can help to promote allocation fairness. We specifically study the effect of presentation format (using text or visualization) and a specific framing strategy (showing resources allocated to groups or individuals). In our three crowdsourced experiments, we provided different tool designs to split money between two fictional programs that benefit two distinct communities. Our main finding indicates that individual-framed visualizations and text may be able to curb unfair allocations caused by group-framed designs. This work opens new perspectives that can motivate research on how interactive tools and visualizations can be engineered to combat cognitive biases that lead to inequitable decisions.

The analytical expression of the QFI of its ground state is evaluated explicitly. And finite-size scaling analysis is performed with the large accessible system size due to the effective bosonic coherent-state technique. We also investigate the large-size scaling behavior of the scaled QFI of the reduced $N$-atom state and show the accurate exponent.

description: In terminal Ediacaran strata of South China, the onset of calcareous biomineralization is preserved in the paleontological transition from Conotubus to Cloudina in repetitious limestone facies of the Dengying Formation. Both fossils have similar size, funnel-in-funnel construction, and epibenthic lifestyle, but Cloudina is biomineralized, whereas Conotubus is not. To provide environmental context for this evolutionary milestone, we conducted a high-resolution elemental and stable isotope study of the richly fossiliferous Gaojiashan Member. Coincident with the first appearance of Cloudina is a significant positive carbonate carbon isotope excursion (up to +6‰) and an increase in the abundance and 34S composition of pyrite. In contrast, δ34S values of carbonate-associated sulfate remain steady throughout the succession, resulting in anomalously large (>70‰) sulfur isotope fractionations in the lower half of the member. The fractionation trend likely relates to changes in microbial communities, with sulfur disproportionation involved in the lower interval, whereas microbial sulfate reduction was the principal metabolic pathway in the upper. We speculate that the coupled paleontological and biogeochemical anomalies may have coincided with an increase in terrestrial weathering fluxes of sulfate, alkalinity, and nutrients to the depositional basin, which stimulated primary productivity, the spread of an oxygen minimum zone, and the development of euxinic conditions in subtidal and basinal environments. Enhanced production and burial of organic matter is thus directly connected to the carbon isotope anomaly, and likely promoted pyritization as the main taphonomic pathway for Conotubus and other soft-bodied Ediacara biotas. Our studies suggest that the Ediacaran confluence of ecological pressures from predation and environmental pressures from an increase in seawater alkalinity set the stage for an unprecedented geobiological response: the evolutionary novelty of animal biomineralization.
Long-term OVRO monitoring of LSI+61303: confirmation of the two close periodicities

description: Context: The gamma-ray binary LSI+61303 shows multiple periodicities. The timing analysis of 6.7 yr of GBI radio data and of 6 yr of Fermi-LAT GeV gamma-ray data both have found two close periodicities P1(GBI) = 26.49 \pm 0.07 d, P2(GBI)=26.92 \pm 0.07 d and P1(gamma)=26.48 \pm 0.08 d, P2(gamma) = 26.99 \pm 0.08 d. Aims: The system LSI+61303 is the object of several continuous monitoring programs at low and high energies. The frequency difference between f1 and f2 of only 0.0006 d(-1) requires long-term monitoring because the frequency resolution in timing analysis is related to the inverse of the overall time interval. The Owens Valley Radio Observatory (OVRO) 40 m telescope has been monitoring the source at 15 GHz for five years and overlaps with Fermi-LAT monitoring. The aim of this work is to establish whether the two frequencies are also resolved in the OVRO monitoring. Methods: We analysed OVRO data with the Lomb-Scargle method. We also updated the timing analysis of Fermi-LAT observations. Results: The periodograms of OVRO data confirm the two periodicities P1(OVRO) = 26.5 \pm 0.1 d and P2(OVRO) = 26.9 \pm 0.1 d. Conclusions: The three indipendent measurements of P1 and P2 with GBI, OVRO, and Fermi-LAT observations confirm that the periodicities are permanent features of the system LSI+61303. The similar behaviours of the emission at high (GeV) and low (radio) energy when the compact object in LSI+61303 is toward apastron suggest that the emission is caused by the same periodically (P1) ejected population of electrons in a precessing (P2) jet.

title: The 19th Kilbrandon Lecture (University of Strathclyde, 27 January 2022) : a rights respecting approach for children who offend: Building on Kilbrandon's vision
Creators: name: Lightowler, Claire
Publisher: name: Strathprints - University of Strathclyde
Year: 2022

description: This lecture was the second to be live-streamed as a webinar during COVID-19 restrictions. Dr Lightowler argued that the experiences of children in conflict with the law demonstrates that we need urgent action of a scale not seen since the Kilbrandon Report (1964). Children in conflict with the law are exposed to significant trauma, adversity, stigma, and injustice. These issues are often exacerbated by contact with the very systems and services intended to support them. Dr Lightowler will demonstrate the transformative change that could be achieved if Scotland viewed children in conflict with the law as rights-holders and devoted greater attention to upholding their rights. The lecture was followed by commentaries by Professor Ursula Kilkelly and Ms Ruth Kerracher, and a vote of thanks by Minister for Children and Early Years in the Scottish Government, Ms Claire Haughey MSP.

description: The Ediacaran Period witnessed the first appearance of macroscopic animal life in Earth's history. However, the biogeochemical context for the stratigraphic occurrence of early metazoans is largely uncertain, in part due to the dearth of integrated paleobiological and chemostratigraphic datasets. In this study, a comprehensive geochemical analysis was conducted on the fossiliferous Khatyspyt Formation in Arctic Siberia, in order to gain insights into the Ediacaran paleoenvironments. This study was designed to specifically address the relationship between paleoredox conditions and Ediacaran fossil occurrences in the Khatyspyt Formation. Our data reveal a dramatic shift in pyrite sulfur isotope compositions (δ34Spyrite) from ca. − 20‰ to ca. 55‰, and this shift is intriguingly associated with the first occurrence of Ediacara-type macrofossils at the studied section, suggesting a possible link between seawater redox conditions and distribution of early macroscopic organisms. Based on multiple lines of sedimentological and geochemical evidence, we propose that the development of oceanic euxinia — which may be widespread in the continental margins due to enhanced oxidative weathering in the terminal Ediacaran Period — may have locally prohibited the colonization of Ediacara-type organisms and resulted in low δ34Spyrite values in the lower Khatyspyt Formation. In the middle and upper Khatyspyt Formation, progressive secular transition from euxinic to non-euxinic and more habitable conditions may have allowed for the colonization of Ediacara-type and other macro-organisms.

description: Li isotopes may be useful tracers of fluid flow in a number of geological environments and case studies of contact aureoles have highlighted the very large Li isotopic fractionation that can be generated in these settings. However, the amount of isotopic fractionation and the distance that Li travels into the country rocks vary greatly from place to place. Seeking to identify the parameters that govern Li distribution in contact aureoles, we apply a combination of Li isotope analyses, 1-D diffusion and 2-D advection-diffusion modeling to two country rock profiles adjacent to Li-rich pegmatite dikes from the Florence County pegmatite field, Wisconsin. Although less than ∼3 m thick, the pegmatite sheets have a large impact on the Li budget of the country rocks (amphibolites and schists); Li is enriched in adjacent country rocks by up to a factor of 20 over more distant amphibolites and schists. Li from the pegmatite has traveled more than 50 m into the country rocks, and Li isotopes are systematically fractionated with distance from the contacts (with δ7Li varying from +6 at the contact to-7 at 30 m from the contact in one case). These observations are consistent with diffusive fractionation of Li through an advecting grain-boundary fluid. Both one-dimensional diffusion and two-dimensional advection-diffusion models fail to reproduce the exact Li distribution in the profiles, suggesting that fluid advection, coupled with heterogeneous permeability, plays an important role in determining the final Li distribution within the contact aureoles.

description: The total cross sections for the $^{152}$Gd(p,$γ$)$^{153}$Tb and $^{152}$Gd(p,n)$^{152}$Tb reactions have been measured by the activation method at effective center-of-mass energies \mbox{$3.47 \leq E_\mathrm{c.m.}^\mathrm{eff}\leq 7.94$ MeV} and \mbox{$4.96 \leq E_\mathrm{c.m.}^\mathrm{eff} \leq 7.94$ MeV}, respectively. The targets were prepared by evaporation of 30.6\% isotopically enriched $^{152}$Gd oxide on aluminum backing foils, and bombarded with proton beams provided by a cyclotron accelerator. The cross sections were deduced from the observed $γ$-ray activity, which was detected off-line by a HPGe detector in a low background environment. The results are presented and compared with predictions of statistical model calculations. This comparison supports a modified optical proton+$^{152}$Gd potential suggested earlier.

description: Ce travail a pour but d’étudier l’influence de l’âge et de l’expérience des professeurs d’éducation physique sur leurs styles et leurs priorités enseignantes. En se référant à la littérature et aux différentes études connues sur le sujet, nous partons de l’hypothèse de départ que plus l’enseignant est expérimenté, plus il priorise le développement moteur de ses élèves. Afin de réfuter ou non cette hypothèse, nous avons effectué une prise de données quantitatives et qualitatives auprès d’enseignants d’éducation physique vaudois et québécois. La prise de données quantitatives s’est faite au travers d’un questionnaire transmis par internet, alors que les données qualitatives ont été récoltées par l’intermédiaire d’entretiens semi-directifs auprès de six enseignants suisses ayant des âges et des niveaux d’expérience bien différents. Nos résultats présentent des contradictions entre les entretiens et les questionnaires. Cependant, nos résultats quantitatifs, formés du plus grand échantillon, valident nos hypothèses en confirmant que plus les enseignants sont expérimentés, plus ils mettent l’accent sur le développement moteur de leurs élèves. Nous discutons ensuite ces différents résultats en les confrontant à plusieurs travaux déjà réalisés sur le sujet. Nous apportons également quelques pistes explicatives tirées de nos propres expériences.

description: We consider fact-checking approaches that aim to predict the veracity of assertions in knowledge graphs. Five main categories of fact-checking approaches for knowledge graphs have been proposed in the recent literature, of which each is subject to partially overlapping limitations. In particular, current text-based approaches are limited by manual feature engineering. Path-based and rule-based approaches are limited by their exclusive use of knowledge graphs as background knowledge, and embedding-based approaches suffer from low accuracy scores on current fact-checking tasks. We propose a hybrid approach -- dubbed HybridFC -- that exploits the diversity of existing categories of fact-checking approaches within an ensemble learning setting to achieve a significantly better prediction performance. In particular, our approach outperforms the state of the art by 0.14 to 0.27 in terms of Area Under the Receiver Operating Characteristic curve on the FactBench dataset. Our code is open-source and can be found at https://github.com/dice-group/HybridFC.

description: Eocene intermediate to felsic subvolcanic rocks of the Torud-Ahmad Abad magmatic belt (TAMB), in the northern part of the Central Iran zone, are exposed between the Torud and Ahmad Abad regions in South-Southeast Shahrood. These igneous rocks include hypabyssal dacite, trachyte, andesite, trachy-andesite, and basaltic andesite; they are mainly composed of phenocrysts and microcrystalline groundmass of pyroxene, amphibole, and plagioclase, with minor biotite and titanomagnetite; they form domal structures (plugs and stocks), dikes, and sills that intruded into Neoproterozoic to cogenetic Eocene volcano-sedimentary sequences. Based on isotopic analysis of these intermediate to acidic rocks, initial ratios of 143Nd/144Nd range from 0.512 775 to 0.512 893 and initial ratios of 87Sr/86Sr range from 0.703 746 to 0.705 314, with quite positive εNd(i) values of +3.69 to +6.00. They are enriched in light rare earth elements and large ion lithophile elements and depleted in heavy rare earth elements and high-field strength elements, the SiO2 content is (52–62) wt.%, and Na2O content >3 wt.%, Al2O3 content >16 wt.%, Yb <1.8 ppm, and Y <18 ppm. These geological, geochemical, and Sr and Nd isotopic data are consistent with adakitic signatures originating by partial melting of the subducted Neo-Tethys oceanic slab (Sabzevar branch) and lithospheric suprasubduction zone mantle. The mantle signatures typifying the rapidly emplaced adakitic rocks (slab (high-silica adakite) and suprasubduction zone (low-silica adakite) melts) together with their locally voluminous extent are evidences that support a locally extensional geodynamic setting; and the evidence is consistent with an evolution to local transpression in the Late Eocene in this convergent margin arc environment to rifting (basalts to adakites) towards submarine conditions in the Neogene.

description: We investigate scaling of work and efficiency of a photonic Carnot engine with the number of quantum coherent resources. Specifically, we consider a generalization of the "phaseonium fuel" for the photonic Carnot engine, which was first introduced as a three-level atom with two lower states in a quantum coherent superposition by [M. O. Scully, M. Suhail Zubairy, G. S. Agarwal, and H. Walther, Science {\bf 299}, 862 (2003)], to the case of $N+1$ level atoms with $N$ coherent lower levels. We take into account atomic relaxation and dephasing as well as the cavity loss and derive a coarse grained master equation to evaluate the work and efficiency, analytically. Analytical results are verified by microscopic numerical examination of the thermalization dynamics. We find that efficiency and work scale quadratically with the number of quantum coherent levels. Quantum coherence boost to the specific energy (work output per unit mass of the resource) is a profound fundamental difference of quantum fuel from classical resources. We consider typical modern resonator set ups and conclude that multilevel phaseonium fuel can be utilized to overcome the decoherence in available systems. Preparation of the atomic coherences and the associated cost of coherence are analyzed and the engine operation within the bounds of the second law is verified. Our results bring the photonic Carnot engines much closer to the capabilities of current resonator technologies.

description: Depuis la commercialisation du Smartphone et l'explosion des réseaux sociaux, la gestion de l'information et de la communication sont devenues une affaire personnelle surtout pour les jeunes adolescents de l'école obligatoire. Cette école a longtemps tourné le dos aux pratiques des écoliers exercées dans leurs cercles privés prétextant qu'il s'agissait de l'éducation des parents. Force est de constater que bon nombre de jeunes adolescents supplantent leurs parents en termes d'utilisation des outils numériques modernes. Si ce n'est l'école, qui donc peut se porter responsable de cette éducation aux médias ? Plus qu'une responsabilité morale, l'école, si elle se veut moderne, active et stimulante, peut utiliser la culture numérique des élèves comme prétexte pour les engager dans des apprentissages multiples. Ce travail a évalué les capacités techniques des élèves pour leur proposer des activités scolaires qui s'alignent sur leur culture numérique. Dans un premier temps, une activité sur Youtube est demandée comme devoirs réguliers, puis, dans un second temps, le visionnage d'une vidéo possédant les caractéristiques qui créent le succès d'une chaîne sur Youtube est montré aux élèves. Les résultats de ces travaux ont montré que les élèves auxquels les deux séquences pédagogiques leur avaient été proposées ont fait preuve d'un certain engagement face à ces activités. Cet engagement n'a pu être possible sans le développement d'une séquence didactique crédible dans sa construction faisant office de guide pour les élèves. La didactique disciplinaire s'est révélée, en effet, comme l'objet décisif permettant aux élèves d'utiliser ces ressources d'une certaine attraction, puisqu'issues de leur culture, à bon escient. En conclusion, ces séquences ont été surtout perçue comme un moyen d'aborder l'efficacité dans la communication de messages ou les problèmes de droits numériques (à l'image, à la propriété intellectuelle, etc.).

description: Coronal bright points (CBP) are ubiquitous small brightenings in the solar corona associated with small magnetic bipoles. We derive the solar differential rotation profile by tracing the motions of CBPs detected by the Atmospheric Imaging Assembly (AIA) instrument aboard the Solar Dynamics Observatory (SDO). We also investigate problems related to detection of coronal bright points resulting from instrument and detection algorithm limitations. To determine the positions and identification of coronal bright points we used a segmentation algorithm. A linear fit of their central meridian distance and latitude versus time was utilised to derive velocities. We obtained 906 velocity measurements in a time interval of only 2 days. The differential rotation profile can be expressed as $ω_{rot} = (14.47\pm 0.10 + (0.6\pm 1.0)\sin^{2}(b) + (-4.7\pm 1.7)\sin^{4}(b))$\degr day$^{-1}$. Our result is in agreement with other work and it comes with reasonable errors in spite of the very short time interval used. This was made possible by the higher sensitivity and resolution of the AIA instrument compared to similar equipment as well as high cadence. The segmentation algorithm also played a crucial role by detecting so many CBPs, which reduced the errors to a reasonable level. Data and methods presented in this paper show a great potential to obtain very accurate velocity profiles, both for rotation and meridional motion and, consequently, Reynolds stresses. The amount of coronal bright point data that could be obtained from this instrument should also provide a great opportunity to study changes of velocity patterns with a temporal resolution of only a few months. Other possibilities are studies of evolution of CBPs and proper motions of magnetic elements on the Sun.

description: The supernova remnant G15.4+0.1 is considered to be the possible counterpart of the gamma-ray source HESSJ1818-154. With the goal of getting a complete view of this remnant and understanding the nature of the gamma-ray flux, we conducted a detailed radio study that includes the search for pulsations and a model of the broadband emission for the G15.4+0.1/HESSJ1818-154 system. Low-frequency imaging at 624 MHz and pulsar observations at 624 and 1404 MHz towards G15.4+0.1 were carried out with the Giant Metrewave Radio Telescope (GMRT). We correlated the new radio data with observations of the source at X-ray and infrared wavelengths from XMM-Newton and Herschel observatories, respectively. To characterize the neutral hydrogen medium (HI) towards G15.4+0.1, we used data from the Southern Galactic Plane Survey. We modelled the spectral energy distribution using both hadronic and leptonic scenarios. From the combination of the new GMRT observations with existing data, we derived a continuum spectral index alpha=-0.62+-0.03 for the whole remnant. The local synchrotron spectra of G15.4+0.1, calculated from the combination of the GMRT data with 330 MHz observations from the VLA, tends to be flatter in the central part of the remnant, accompanying the region where the blast wave is impinging molecular gas. No spectral index trace was found indicating the radio counterpart to the pulsar wind nebula proposed from X-ray observations. In addition, the search for radio pulsations yielded negative results. Emission at far-infrared wavelengths is observed in the region where the SNR shock is interacting with dense molecular clumps. We also identified HI features forming a shell that wraps most of the outer border of G15.4+0.1. Characteristic parameters were estimated for the shocked HI gas. We found that either a purely hadronic or leptonic model is compatible with the broadband emission known so far.

description: L’objectif principal de cette étude est d’analyser l’effet d’un support vidéo dans le processus d’apprentissage des élèves en EPS dans deux écoles de niveau secondaire 1 du canton de Vaud. Basé sur un modèle permettant d’évaluer l’intérêt en situation (IS) dans les cours d’EPS, ce présent travail se penche sur les feedbacks donnés à l’aide d’un support vidéo comme moyen permettant d’améliorer la motivation des élèves lors d’un exercice tactique au handball. L’outil (questionnaire IS, Roure 2016) nous a permis d’évaluer les effets des retours vidéos sur l’IS des élèves au cours de l’activité proposée. Les résultats obtenus n’ont pas montré de différence significative sur l’intérêt total des élèves entre les leçons accompagnées de feedbacks oraux (sans vidéo) et les leçons guidées par des feedbacks vidéos. Nous avons également pu constater qu’il existe une relation de proportionnalité entre l’intérêt individuel et l’intérêt en situation : plus l’élève est intéressé par le handball plus son intérêt en situation sera élevé et inversement. Ces constats nous mènent à la réflexion sur l’utilisation d’un support vidéo. Souvent présenté comme un outil miracle, ce présent travail réfute cette croyance et prouve que le numérique n’est donc pas la panacée dans le domaine de l’enseignement. Il doit être utilisé avec parcimonie et justesse. Il peut se montrer intéressant dans certaines activités et dans certains contextes. De plus, cette étude nous aura aussi permis de comprendre que l’intérêt individuel influence fortement l’intérêt en situation. Il est donc du devoir de l’enseignant d’élaborer des tâches motivantes permettant à ceux qui ne sont pas intrinsèquement attirés par le sport proposé de s’engager dans la leçon. De manière générale, cette présente recherche nous a fait réfléchir au sujet du rôle primordial de l’enseignant que ce soit dans la réflexion lors de l’élaboration d’une leçon ou dans l’utilisation de tout type d’outil didactique.

description: This paper presents the linear theory of adjoint equations as applied to thermo-acoustics. The purpose is to describe the mathematical foundations of adjoint equations for linear sensitivity analysis of thermo-acoustic systems, recently developed by Magri and Juniper (J. Fluid Mech. (2013), vol. 719, pp. 183--202). This method is applied pedagogically to a damped oscillator, for which analytical solutions are available, and then for an electrically heated Rijke tube with a mean-flow temperature discontinuity induced by the compact heat source. Passive devices that most affect the growth rate / frequency of the electrical Rijke-tube system are presented, including a discussion about the effect of modelling the mean-flow temperature discontinuity.

From single-shot towards general work extraction in a quantum thermodynamic framework

description: This paper considers work extraction from a quantum system to a work storage system (or weight) following reference [1]. An alternative approach is here developed that relies on the comparison of subspace dimensions without a need to introduce thermo-majorisation used previously. Optimal single shot work for processes where a weight transfers from (a) a single energy level to another single energy level is then re-derived. In addition we discuss the final state of the system after work extraction and show that the system typically ends in its thermal state, while there are cases where the system is only close to it. The work of formation in the single level transfer setting [1] is also re-derived. The approach presented now allows the extension of the single shot work concept to work extraction (b) involving multiple final levels of the weight. A key conclusion here is that the single shot work for case (a) is appropriate only when a \emph{resonance} of a particular energy is required. When wishing to identify "work extraction" with finding the weight in a specific available energy or any higher energy a broadening of the single shot work concept is required. As a final contribution we consider transformations of the system that (c) result in general weight state transfers. Introducing a transfer-quantity allows us to formulate minimum requirements for transformations to be at all possible in a thermodynamic framework. We show that choosing the free energy difference of the weight as the transfer-quantity one recovers various single shot results including single level transitions (a), multiple final level transitions (b), and recent results on restricted sets of multi-level to multi-level weight transfers.

Who were the first urban settlers of Oslo? A discussion of early medieval urbanization based on isotopic analyses of human remains

description: This paper investigates the process of early urbanization in Oslo, Norway, during the initial period of early 11th–late 12th Century using a bioarchaeological approach. Through the use of isotope analyses performed on teeth and bone from 20 humans buried in Oslo during the first phases of urban settlement, individual dietary change and mobility are reconstructed. Oslo is traditionally perceived as one of many urban settlements initiated by royal power, and this paper contributes to this discussion by investigating the origin of the first settlers, and also how the early urban process affected their way of living. Results suggest that most individuals in the study were of local origin, and had a constant diet throughout life from childhood to its last phase. The absence of individual dietary change sharply contrasts the dynamic dietary patterns observed in people from the Viking age. Dietary variation between individuals does suggest, however, social differences among the early urban population of Oslo.
Can a Dove prism change the past of a single photon?

description: We reexamine the thought experiment and real experiment of Vaidman et al., by placing Dove prisms in the nested Mach-Zehnder interferometer arms. In those previous works, the criterion of whether a single photon was present, or not, was the presence of a "weak trace", indicating the presence of a nonzero weak value. This was verified by slightly varying the mirror angle at a given frequency, which was then detected on a position sensitive detector at the oscillation frequency. We show the presence of the Dove prisms gives identical weak values everywhere to the previous configuration because the prisms change neither the path difference, nor the mode profile in the aligned case. Nevertheless, the same slight variations of the interferometer mirrors now give a signal at the first mirror of the nested interferometer. We can interpret this result as a misaligned optical interferometer, whose detailed response depends on the stability of the elements, or as the detector coupling to a nonzero effective weak value.

Interpreting two-dimensional cuts through broken geologic objects: Fractal and non-fractal size distributions
Creators: name: Mills, R.D.
name: Glazner, A.F.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2012

description: Numerical simulations and physical fragmentation experiments confirm the theoretical prediction that the fractal dimension of a two-dimensional (2-D) cut through a set of three-dimensional objects with fractal dimension D is approximately equal to D - 1. This leads to a size distribution in twodimensional cuts that is skewed strongly toward larger objects compared to the three-dimensional distribution. Threedimensional shape (aspect ratio) does not significantly affect the resulting 2-D size distribution except for highly nonequant objects, such as prolate ellipsoids with aspect ratios of 10 or more. In contrast, fragmentation of an object by breakage along persistent fractures results in a non-fractal distribution of sizes and far fewer small objects than predicted by fractal statistics. Powdering a rock by extensive crushing also results in non-fractal size distributions because particles are reduced to sizes on the order of 1 m, a comminution limit below which further brittle fracture is difficult. Natural examples of fragmental objects observed in two-dimensional cuts, such as crushed rocks, breccias, and xenoliths, are generally consistent with a three-dimensional fractal dimension near 2.5 over one or two orders of magnitude in size. However, a limestone breccia from Death Valley exhibits a nonfractal size distribution consistent with fragmentation of a strongly jointed rock. Mafic enclaves in Yosemite National Park have a restricted size range of about one order of magnitude and a three-dimensional fractal dimension of ~3.1, consistent with other enclave swarms. The restricted size range of enclaves may reflect the apertures of mafic dikes that fed them.
