description: Different network models have been suggested for the topology underlying complex interactions in natural systems. These models are aimed at replicating specific statistical features encountered in real-world networks. However, it is rarely considered to which degree the results obtained for one particular network class can be extrapolated to real-world networks. We address this issue by comparing different classical and more recently developed network models with respect to their generalisation power, which we identify with large structural variability and absence of constraints imposed by the construction scheme. After having identified the most variable networks, we address the issue of which constraints are common to all network classes and are thus suitable candidates for being generic statistical laws of complex networks. In fact, we find that generic, not model-related dependencies between different network characteristics do exist. This allows, for instance, to infer global features from local ones using regression models trained on networks with high generalisation power. Our results confirm and extend previous findings regarding the synchronisation properties of neural networks. Our method seems especially relevant for large networks, which are difficult to map completely, like the neural networks in the brain. The structure of such large networks cannot be fully sampled with the present technology. Our approach provides a method to estimate global properties of under-sampled networks with good approximation. Finally, we demonstrate on three different data sets (C. elegans' neuronal network, R. prowazekii's metabolic network, and a network of synonyms extracted from Roget's Thesaurus) that real-world networks have statistical relations compatible with those obtained using regression models.
Improving the evidence for European migration policy making

Subjects: migration, population, projections, Eu, age, sex, level of education, country of origin

description: This policy brief synthesizes central results from quantitative migration and population projections that were produced as part of the FUME project. The projections model future migration flows to and within the EU and project the population in EU member states at an unprecedented level of detail, including by age, sex, level of education, and country of origin. In addition, FUME projections cover various spatial levels, from the international to the national to the local. This policy brief also describes how emerging big data sources were used to gain a better understanding of migration flows. It concludes by highlighting key messages and recommendations. The Horizon 2020 project ‘Future migration scenarios for Europe (FUME)’ focuses on understanding the patterns, motivations, and modalities of migration at multiple geographical scales, from international through regional to the local, and on developing possible future scenarios of migration to Europe. These scenarios shall improve our understanding of the complexity and diversity of migration – and support migration policies, integration measures, labour market and cohesion policies at different governance levels.

description: High magnetic fields are a distinguishing feature of neutron stars and the existence of sources (the soft gamma repeaters and the anomalous X-ray pulsars) hosting an ultra-magnetized neutron star (or magnetar) has been recognized in the past few decades. Magnetars are believed to be powered by magnetic energy and not by rotation, as with normal radio pulsars. Until recently, the radio quietness and magnetic fields typically above the quantum critical value (Bq~4.4x10^{13} G), were among the characterizing properties of magnetars. The recent discovery of radio pulsed emission from a few of them, and of a low dipolar magnetic field soft gamma repeater, weakened further the idea of a clean separation between normal pulsars and magnetars. In this Letter we show that radio emission from magnetars might be powered by rotational energy, similarly to what occurs in normal radio pulsars. The peculiar characteristics of magnetars radio emission should be traced in the complex magnetic geometry of these sources. Furthermore, we propose that magnetar radio activity or inactivity can be predicted from the knowledge of the star's rotational period, its time derivative and the quiescent X-ray luminosity.

Bad Serine 170 - regulation and cellular effects
Creators: name: Waissbluth, Ivan
Publisher: name: University of British Columbia
Year: 2009

description: The balance between cell proliferation and cell death is imperative for homeostasis in multicellular organisms. This homeostasis had long been thought to be the result of two separate processes, but there is recent evidence indicating that the processes of proliferation and apoptosis are coupled. Here we demonstrate that Bad, a proapoptotic member of the Bcl-2 family of proteins that is thought to exert a deathpromoting effect by heterodimerization with Bcl-xL, is able to interact directly with the cell cycle machinery. Immunoprecipitation experiments indicate that Bad interacts with both Cdk2 and its late Gi cyclin partner, Cyclin E. This finding is relevant as we also demonstrate that prior to the conversion of Bad into a death factor; Bad’s phosphorylation state in healthy mammalian cells, specifically at Ser- 170, is able to influence cell cycle progression. Here we show that transfection with Bad Si 70A, a mutant form of Bad which mimics the unphosphorylated form, results in a prolonged S phase during cell cycle. We also show that the kinase activity towards Bad Ser- 170 increases in S phase of the cell cycle. Together this suggests that Bad Ser-170 is a phosphorylation site which is targeted during S phase and is able to interfere with the normal progression through S phase of the cell cycle. From this, it was of interest to elucidate the kinase responsible for phosphorylating Bad at Ser-170 as it may provide insight into signal transduction pathways that converge in terms of controlling both survival and cell proliferation, and ultimately cell expansion. Through a process of column purification, usage of chemical inhibitors, and gene knockdown, we show evidence that CaMKII-γ mediates the phosphorylation of Bad Ser 170, thus establishing a novel connection between CaMKII signaling and apoptosis in hematopoietic cells. We hypothesize that CaMKII-γ plays a major role in controlling Bad’s ability to induce apoptosis and to affect cell cycle progression, by controlling Bad’s phosphorylation state at Ser-170.

description: We present results for B-meson decay modes involving a charm meson, protons, and pions using 455 x 10^6 BBbar pairs recorded by the BaBar detector at the SLAC PEP-II asymmetric-energy e+ e- collider. The branching fractions are measured for the following ten decays: B0bar to D0 p pbar, B0bar to D*0 p pbar, B0bar to D+ p pbar pi-, B0bar to D*+ p pbar pi-, B- to D0 p pbar pi-, B- to D*0 p pbar pi-, B0bar to D0 p pbar pi- pi+, B0bar to D*0 p pbar pi- pi+, B- to D+ p pbar pi- pi-, and B- to D*+ p pbar pi- pi-, The four B- and the two five-body B0bar modes are observed for the first time. The four-body modes are enhanced compared to the three- and the five-body modes. In the three-body modes, the M(p pbar) and M(D(*)0 p) invariant mass distributions show enhancements near threshold values. In the four-body mode B0bar to D+ p pbar pi-, the M(p pi-) distribution shows a narrow structure of unknown origin near 1.5 GeV/c^2. The distributions for the five-body modes, in contrast to the others, are similar to the expectations from uniform phase-space predictions.

"The Echo, Not the Shot" : metamorphosis and mediation in William Faulkner
Creators: name: Smith, Philip Anthony James
Publisher: name: University of British Columbia
Year: 2009

description: This thesis is an attempt to situate and contextualize William Faulkner’s novels of the 1930s within the framework of the emerging mass culture forms of that period, and to investigate this author’s assimilation and inversion of the structures and the stylistic and formalistic devices afforded not only by film, but by animated cartoons, newsreels, and radio. Faulkner’s works are fully immersed in and reflective of a world of metamorphosis and mediation engendered by these mass culture forms, a world when social and artistic hierarchies also fully enter the modernist period of incessant flux. Chapter One will offer a brief overview of the perceptual and literary effects engendered in the early days of media culture as it may apply to Faulkner and his contemporary Sherwood Anderson, including a growing loathing of what was seen as an increasing tendency toward “standardization” in both literature and life. For Faulkner however the media culture which was partially responsible for standardization also provided new formal possibilities through which the writer could address it. Chapter Two will focus on two of Faulkner’s most beloved popular culture forms -the animated cartoon and the newsreel - and their relation to Light in August, Absalom, Absalom! and Pylon in particular. The interpolation and recuperation of mass culture devices and motifs and the concern with a standardized world reach an apotheosis in the 1939 novel "If I Forget Thee, Jerusalem" (now known as The Wild Palms), a work which also can be seen as the culmination of Faulkner’s decade-long experiments in the use of multiple narrative voices. Chapter Three of the thesis will examine this novel’s and its narrators’ relation to the contemporaneous culture of cacophony these media arts were producing, in particular that of radio’s. As this book also functions as a cautionary tale as to the convergence of writing and mass culture, Chapter Four will discuss the double transfiguration of genre codes and restrictions found within Jerusalem, as well as briefly examine the acceleration of the culture of celebrity and the attendant fragmenting mediation of literary works found in the later media age (that of television).

description: In 1967 Wolk proved that every well partial order (wpo) has a maximal chain; that is a chain of maximal order type. (Note that all chains in a wpo are well-ordered.) We prove that such maximal chain cannot be found computably, not even hyperarithmetically: No hyperarithmetic set can compute maximal chains in all computable wpos. However, we prove that almost every set, in the sense of category, can compute maximal chains in all computable wpos. Wolk's original result actually shows that every wpo has a strongly maximal chain, which we define below. We show that a set computes strongly maximal chains in all computable wpo if and only if it computes all hyperarithmetic sets.

description: We revisit the construction of puncture black hole initial data in the conformal thin-sandwich decomposition of Einstein's constraint equations. It has been shown previously that this approach cannot yield quasiequilibrium wormhole data, which connect two asymptotically flat spatial infinities. This argument does not apply to trumpet data, which connect the spatial infinity in one universe with the future timelike infinity of another. As a numerical demonstration we present results for a single boosted trumpet-puncture black holes, constructed in the original version of the conformal thin-sandwich formalism.

description: Single-particle momentum spectra for a dynamically evolving one-dimensional Bose gas are analysed in the semi-classical wave limit. Representing one of the simplest correlation functions these give information about possible universal scaling behaviour. Motivated by the previously discovered connection between (quasi-)topological field configurations, strong wave turbulence, and nonthermal fixed points of quantum field dynamics, soliton formation is studied with respect to the appearance of transient power-law spectra. A random-soliton model is developed to describe the spectra analytically, and the analogies and difference between the appearing power laws and those found in a field theory approach to strong wave turbulence are discussed. The results open a view on solitary wave dynamics from the point of view of critical phenomena far from thermal equilibrium and on a possibility to study this dynamics in experiment without the necessity of detecting solitons in situ.

description: The recent trend towards the application of deep structured techniques has revealed the limits of huge models in natural language processing. This has reawakened the interest in traditional machine learning algorithms, which have proved still to be competitive in certain contexts, in particular low-resource settings. In parallel, model selection has become an essential task to boost performance at reasonable cost, even more so when we talk about processes involving domains where the training and/or computational resources are scarce. Against this backdrop, we evaluate the early estimation of learning curves as a practical mechanism for selecting the most appropriate model in scenarios characterized by the use of non-deep learners in resource-lean settings. On the basis of a formal approximation model previously evaluated under conditions of wide availability of training and validation resources, we study the reliability of such an approach in a different and much more demanding operationalenvironment. Using as case study the generation of PoS taggers for Galician, a language belonging to the Western Ibero-Romance group, the experimental results are consistent with our expectations.

Our SA is based on a new way of abstracting statement-level control-flow information to a representation with a graphical view that allows an intuitive identification of several provided patterns. Our DA is based on sequence alignments and only needs the position and size information of the functions. We manually validate the SA on a set of diverse executables and in one detailed case study, and automatically validate the DA on three sets of executables, namely sets of similar and dissimmilar executables as well as a set of academic executables obtained from a third party.

description: Eine Personalentwicklungsmassnahme gegen den aktuellen Fachkräftemangel bei der Stadt Luzern könnte die Realisierung eines Traineeprogramms sein. Die vorliegende Arbeit beantwortet die Fragestellung, was aus theoretischer und praktischer Perspektive Merkmale und Erfolgsfaktoren von Traineeprogrammen sind und wie sie sich in einem Grobkonzept für die Stadt Luzern realisieren lassen. Die Daten wurden qualitativ in Interviews mit Personen aus Unternehmen, welche bereits ein Traineeprogramm anbieten, und mit einer quantitativen Umfrage bei der Stadt Luzern, erhoben. Die Merkmale eines Traineeprogramms zeigen sich in der Organisation, in der Ausbildungsform, an der Ansprechperson für die Trainees, an der Gesamtdauer des Traineeprogramms und in den Job-Rotationen. Wichtige Erfolgsfaktoren sind die personellen Ressourcen und die Akzeptanz beziehungsweise die Bereitschaft des Teams, ein:e Trainee aufzunehmen. Auf Basis der Literatur sowie der qualitativen und quantitativen Datenerhebung wird für die Stadt Luzern ein Grobkonzept für zwei Traineeprogramme vorgeschlagen. Aufgrund der aktuellen Gegebenheiten bei der Stadt Luzern wären Traineeprogramme für Hochschulabsolvent:innen der Studiengänge (Umwelt-)Ingenieurwesen und Informatik geeignet. Die Investition in ein Traineeprogramm gegen den Fachkräftemangel und für die Ausbildung von Führungspersonen lohnt sich.

description: We present 230 GHz Submillimeter Array continuum and molecular line observations of the newly discovered FUor candidate HBC722. We report the detection of seven 1.3 mm continuum sources in the vicinity of HBC722, none of which correspond to HBC722 itself. We compile infrared and submillimeter continuum photometry of each source from previous studies and conclude that three are Class 0 embedded protostars, one is a Class I embedded protostar, one is a Class I/II transition object, and two are either starless cores or very young, very low luminosity protostars or first hydrostatic cores. We detect a northwest-southeast outflow, consistent with the previous detection of such an outflow in low-resolution, single-dish observations, and note that its axis may be precessing. We show that this outflow is centered on and driven by one of the nearby Class 0 sources rather than HBC722, and find no conclusive evidence that HBC722 itself is driving an outflow. The non-detection of HBC722 in the 1.3 mm continuum observations suggests an upper limit of 0.02 solar masses for the mass of the circumstellar disk. This limit is consistent with typical T Tauri disks and with a disk that provides sufficient mass to power the burst.

Locating the ideal homeland in the literature of Edwidge Danticat
Creators: name: Okot Bitek, Juliane
Publisher: name: University of British Columbia
Year: 2009

description: Edwidge Danticat, who has lived most of her life in the United States, retains a strong link with Haiti and primarily writes about the Haitian experience inside and outside the country. For Danticat, the ‘ideal homeland’ is a psychic space where she can be Haitian, American, and belong to both countries. Danticat's aspiration and position as one who can make claim to both Haiti and the United States somewhat supports Stuart Hall’s notion of cultural identity as a fluid entity and an identity that is becoming and is, not one that is static and was. However, Danticat locates her ‘ideal homeland’ within the Haitian Dyaspora, as a social construct that includes all the people of the Haitian descent in the diaspora, whatever their countries of citizenship. This ideal homeland is an emotional and literary space for continued expression and creation of Haitian identity, history and culture. It is not a geographical space and as such, requires that membership in it engage through text. This paper investigates ways in which Danticat expresses the ideal homeland in her fiction and nonfiction works. I use Dionne Brand, Kamau Brathwaite, Edward Soja and Judith Lewis Herman among others, as theorists to discover this ideal homeland in order to show that Danticat, like many diasporic writers, is actively engaged in locating for themselves where they can engage in their work as they create new communities and take charge of how they tell their stories and how they identify themselves. Danticat’ s work is a valuable contribution to the re-clamation of the Haitian storytelling tradition which she writes in English to a readership that is wider than the borders of both United States and Haiti, thereby redefining the Haitian borders and indeed, the citizenship of who can claim Haitian-ness by being able to relate to and access her work.

description: Aerated chocolate is one important lipid based product and its texture differentiation is of great importance for the food industry. The aim of this project is to find the most suitable process control for various dimensions of consumer preference. The high pressure aeration was experimentally investigated with the aim to develop a kinetic model of foam formation. It was found, that the differentiation through product texture can be realised by varying the chocolate composition or the process parameters. A MATLAB Model for the prediction of bubble formation, growth and coalescence was successfully developed and evaluated. This findings could further enable a better control of the chocolate aeration process to obtain the production of various aerated chocolate products.

Evolution of proto-neutron stars with the hadron-quark phase transition

description: The Poyakov-Nambu-Jona-Lasinio (PNJL) model was developed recently, which includes both the chiral dynamics and (de)confinement effect and gives a good description of lattice QCD data. In this study we use the PNJL model to describe the quark phase, and first use it to study the evolution of proto-neutron star (PNS) with a hadron-quark phase transition. Along the line of a PNS evolution, we take several snapshots of PNS profiles, presenting the fractions of different species, the equations of state (EOS), and the mass-radius relations at different stages. The calculation shows the mixed phase may exist during the whole evolving process, and the onset density of quark phase decreases with the radiation of neutrinos in the heating stage. In the cooling stage, the EOS of the mixed phase softens and the center density increases. In this process a part of nuclear matter transforms to quark matter, which may lead to a PNS collapsing into a black hole.

description: The distribution of dust in the ecliptic plane between 0.96 and 1.04 AU has been inferred from impacts on the two STEREO spacecraft through observation of secondary particle trails and unexpected off-points in the Heliospheric Imager (HI) cameras. This study made use of analysis carried out by members of a distributed web-based project, Solar Stormwatch. A comparison between observations of the brightest particle trails and a survey of fainter trails shows consistent distributions. While there is no obvious correlation between this distribution and the occurrence of individual meteor streams at Earth, there are some broad longitudinal features in these distributions that are also observed in sources of the sporadic meteor population. The asymmetry in the number of trails seen by each spacecraft and the fact that there are many more unexpected off-points in the HI-B than in HI-A, indicates that the majority of impacts are coming from the apex direction. For impacts causing off-points in the HI-B camera these dust particles are estimated to have masses in excess of 10-17 kg with radii exceeding 0.1 μm. For off-points observed in the HI-A images, which can only have been caused by particles travelling from the anti-apex direction, the distribution is consistent with that of secondary 'storm' trails observed by HI-B, providing evidence that these trails also result from impacts with primary particles from an anti-apex source. It is apparent that the differential mass index of particles from the apex direction is consistently above 2. This indicates that the majority of the mass is within the smaller particles of this population. In contrast, the differential mass index of particles from the anti-apex direction (causing off-points in HI-A) is consistently below 2, indicating that the majority of the mass is to be found in larger particles of this distribution.

description: We studied different levels of resummations of the exactly solvable Bloch-Nordsieck model in order to be able to compare the approximations with an exact result. We studied one-loop perturbation theory, 2PI resummation and Schwinger-Dyson equations truncated in a way to maintain Ward-identities. At all levels we carefully performed renormalization. We found that although the 2PI resummation does not exhibit infrared sensitivity at the mass shell (the one-loop perturbation theory does), but it is still far from the exact solution. The method of truncated Schwinger-Dyson equations, however, is exact in this model, so it provides a new way of solving the Bloch-Nordsieck model. This method can also be generalized to other, more complicated theories.

Considering, for example, the advances in CMB science made possible by Boltzmann-solvers such as CMBFast, CAMB and CLASS, there are clear precedents for how theorists working in a well-defined subfield can mutually benefit from such a code base. Motivated by these and other examples, I present Halotools: an open-source, object-oriented python package for building and testing models of the galaxy-halo connection. Halotools is community-driven, and already includes contributions from over a dozen scientists spread across numerous universities. Designed with high-speed performance in mind, the package generates mock observations of synthetic galaxy populations with sufficient speed to conduct expansive MCMC likelihood analyses over a diverse and highly customizable set of models. The package includes an automated test suite and extensive web-hosted documentation and tutorials (halotools.readthedocs.org). I conclude the talk by describing how Halotools can be used to analyze existing datasets to obtain robust and novel constraints on galaxy evolution models, and by outlining the Halotools program to prepare the field of cosmology for the arrival of Stage IV dark energy experiments.

description: In \cite{hZ09}, Zessin constructed the so-called Pólya sum process via partial integration technique. This process shares some important properties with the Poisson process such as complete randomness and infinite divisibility. This work discusses H-sufficient statistics for the Pólya sum process as it was done for the Poisson process in \cite{hZ76}.

description: The Causal Dynamical Triangulation model of quantum gravity (CDT) has a transfer matrix, relating spatial geometries at adjacent (discrete lattice) times. The transfer matrix uniquely determines the theory. We show that the measurements of the scale factor of the (CDT) universe are well described by an effective transfer matrix where the matrix elements are labeled only by the scale factor. Using computer simulations we determine the effective transfer matrix elements and show how they relate to an effective minisuperspace action at all scales.

description: Carbon-enhanced metal-poor (CEMP) stars are believed to show the chemical imprints of more massive stars (M > 0.8 Msun) that are now extinct. In particular, it is expected that the observed abundance of Li should deviate in these stars from the standard Spite lithium plateau. We study here a sample of 11 metal-poor stars and a double-lined spectroscopic binary with -1.8

Quantum interference in timed Dicke basis and its effect on bipartite entanglement

Subjects: subject: Quantum Physics (quant-ph)

description: We analyze the effect of position dependent excitation phase on the properties of entanglement between two qubits formed in atomic systems. We show that the excitation phase induces a vacuum mediated quantum interference in the system that affects the dynamical behavior of entanglement between the qubits. It is also found that the quantum interference leads to a coherent population transfer between the symmetric and antisymmetric states which can considerably modify the dynamics of two-qubit entanglement and can even prevent finite time disentanglement (sudden death) under certain conditions.

description: A theoretical description of the radial density profile for charged particles with Yukawa interaction in a harmonic trap is described. At strong Coulomb coupling shell structure is observed in both computer simulations and experiments. Correlations responsible for such shell structure are described here using a recently developed model based in density functional theory. A wide range of particle number, Coulomb coupling, and screening lengths is considered within the fluid phase. A hypernetted chain approximation shows the formation of shell structure, but fails to give quantitative agreement with Monte Carlo simulation results at strong coupling. Significantly better agreement is obtained within the hypernetted chain structure using a renormalized coupling constant, representing bridge function corrections.

description: Neue Anwendungsgebiete für amorphes Silizium in der integrierten Optik werden entwickelt. Zunächst wird der Einfluss der Methode der Abscheidung sowie der Prozessparameter auf die Materialeigenschaften untersucht. Die Auswirkungen einer thermischen Nachbehandlung werden analysiert. Verlustarme, einmodige Wellenleiter werden hergestellt. Zudem wird Plasma-unterstützte Abscheidung aus der Gasphase genutzt, um dreidimensionale Taper mit Hilfe von Schattenmasken zu realisieren. Die Möglichkeit des Stapelns von Wellenleitern unter Anwendung eines Planarisierungsprozesses wird untersucht, und vertikales Koppeln zwischen den Wellenleitern wird simuliert, um Spezifikationen für die beteiligten Herstellungsprozesse abzuleiten. Darüberhinaus werden horizontal geschlitzte Wellenleiter hergestellt.
description: New fields of application for amorphous silicon in integrated optics are developed. First, the influence of deposition method and process parameters on the material properties is investigated. The effects of thermal treatments are analyzed. Low-loss, monomode waveguides are fabricated. Then, a low-temperature PECVD process is used to realize a three-dimensional taper concept with shadow masks. The feasibility to stack waveguides application of a planarization process is studied, and vertical coupling between waveguides is simulated in order to estimate process specifications. Furthermore, waveguides with horizontal slots are fabricated.
Galactic substructure traced by RR Lyraes in SDSS Stripe 82

description: Using a sample of 407 RR Lyrae stars extracted from SDSS Stripe 82, we study the degree of substructure in the Galactic halo. We identify overdensities associated with the known substructures of the Hercules-Aquila Cloud and the Sagittarius Stream, and find a further previously-unknown substructure, the Pisces Overdensity, at ~100 kpc from the Sun. Together, the three substructures account for ~80% of our RR Lyrae sample. We also study the density distribution of RR Lyraes in the halo and find that the profile is best fit by a broken power law with an inner slope of -2.4 and a break radius of ~25 kpc, consistent with previous studies. We conclude that the halo is predominantly made up of the debris from in-falling satellites, with little or no underlying smooth component.

description: Die Dissertation beschäftigt sich mit der Entwicklung der taktischen Optimierungsmodelle für globale und regionale Containersteuerung. Die Modelle beinhalten gemeinsame, spezifische Durchschnittsparameter, die den Zusammenhang zwischen den Steuerungsebenen ermöglichen. Die Probleme werden als dynamische Netzwerkflussmodelle formuliert welche mit Gurobi 6.5.0 gelöst werden. Das Ziel ist die Maximierung des Gesamtgewinns aus der Containersteuerung. Das Maritime Modell beinhaltet eine realistischere Darstellung des kurzfristigen Leasings und ermöglicht die Untersuchung des Einsatzes von angemieteten Containern im globalen Transportnetzwerk in verschiedenen Szenarien. Das Inland Modell berücksichtigt eine Strategie zur Reduzierung der landseitigen Transportdienste einer Reederei und demonstriert ihre Optimierungspotenzial in bestimmten Umgebungen.
description: The thesis proposes the tactical optimization models for global and regional container management. Both models incorporate certain common parameters, which enable the interconnection and coherence between the models. The problems are formulated as dynamic network flow models that seek to maximize the total profit from container management, and solved using Gurobi 6.5.0. The Maritime Model includes a more realistic representation of the short-term leasing, and enables the study of the deployment of leased containers in the global shipping network in different scenarios. The Inland Model considers an option of restricting the carrier’s inland transport services, and demonstrates that it can present an optimization potential in certain settings.

description: We have synthesized the intermetallic YPrFe17 compound by arc-melting. X-ray and neutron powder diffraction show that the crystal structure is rhombohedral with View the MathML source space group (Th2Zn17-type). The investigated compound exhibits a broad isothermal magnetic entropy change ΔSM(T) associated with the ferro-to-paramagnetic phase transition (TC \approx 290 K). The |ΔSM| (\approx 2.3 J kg-1 K-1) and the relative cooling power (\approx 100 J kg-1) have been calculated for applied magnetic field changes up to 1.5 T. A single master curve for ΔSM under different values of the magnetic field change can be obtained by a rescaling of the temperature axis. The results are compared and discussed in terms of the magneto-caloric effect in the isostructural R2Fe17 (R = Y, Pr and Nd) binary intermetallic alloys.
