description: This article introduces Transition 2.0, a paradigm shift designed to study and support students with disabilities’ transition to higher education. Transition 2.0 is the result of a qualitative study about how a group of young people with vision impairments used digital technologies for their transition to university. The findings draw from observations, a researcher diary, focus groups, individual interviews, and data from social media. The article discusses a conventional view of transition, referred to here as Transition 1.0, which has dominated disability-related research and service provision in higher education. It counters this view by further developing the conceptual framework for Transition 2.0. The findings expand current conceptual approaches to transition by incorporating in the analysis the role played by digital tools such as social media and mobile devices. They also provide a new lens through which to study and understand student engagement in higher education.

description: We analyzed a 115 ks XMM-Newton observation and the stacking of 8 days of INTEGRAL observations, taken during the raise of the 2015 outburst of the accreting millisecond X-ray pulsar SAX J1748.9-2021. The source showed numerous type-I burst episodes during the XMM-Newton observation, and for this reason we studied separately the persistent and burst epochs. We described the persistent emission with a combination of two soft thermal components, a cold thermal Comptonization component (~2 keV) and an additional hard X-ray emission described by a power-law (photon index ~2.3). The continuum components can be associated with an accretion disc, the neutron star (NS) surface and a thermal Comptonization emission coming out of an optically thick plasma region, while the origin of the high energy tail is still under debate. In addition, a number of broad (~0.1-0.4 keV) emission features likely associated to reflection processes have been observed in the XMM-Newton data. The estimated 1.0-50 keV unabsorbed luminosity of the source is ~5x10^37 erg/s, about 25% of the Eddington limit assuming a 1.4 solar mass NS. We suggest that the spectral properties of SAX J1748.9-2021 are consistent with a soft state, differently from many other accreting X-ray millisecond pulsars which are usually found in the hard state. Moreover, none of the observed type-I burst reached the Eddington luminosity. Assuming that the burst ignition and emission are produced above the whole NS surface, we estimate a neutron star radius of ~7-8 km, consistent with previous results.

description: In this note the Chernoff Theorem is used to approximate evolution semigroups constructed by the procedure of subordination. The considered semigroups are subordinate to some original, unknown explicitly but already approximated by the same method, counterparts with respect to subordinators either with known transitional probabilities, or with known and bounded Lévy measure. These results are applied to obtain approximations of semigroups corresponding to subordination of Feller processes, and (Feller type) diffusions in Euclidean spaces, star graphs and Riemannian manifolds. The obtained approximations are based on explicitly given operators and hence can be used for direct calculations and computer modelling. In several cases the obtained approximations are given as iterated integrals of elementary functions and lead to representations of the considered semigroups by Feynman formulae.

description: Variable emission is one of the defining characteristic of active galactic nuclei (AGN). While providing precious information on the nature and physics of the sources, variability is often challenging to observe with time- and field-of-view-limited astronomical observatories such as Imaging Atmospheric Cherenkov Telescopes (IACTs). In this work, we address two questions relevant for the observation of sources characterized by AGN-like variability: what is the most time-efficient way to detect such sources, and what is the observational bias that can be introduced by the choice of the observing strategy when conducting blind surveys of the sky. Different observing strategies are evaluated using simulated light curves and realistic instrument response functions of the Cherenkov Telescope Array (CTA), a future gamma-ray observatory. We show that strategies that makes use of very small observing windows, spread over large periods of time, allows for a faster detection of the source, and are less influenced by the variability properties of the sources, as compared to strategies that concentrate the observing time in a small number of large observing windows. Although derived using CTA as an example, our conclusions are conceptually valid for any IACTs facility, and in general, to all observatories with small field of view and limited duty cycle.

description: We examine the effect of an accretion disc on the orbits of stars in the central star cluster surrounding a central massive black hole by performing a suite of 39 high-accuracy direct N-body simulations using state-of-the art software and accelerator hardware, with particle numbers up to 128k. The primary focus is on the accretion rate of stars by the black hole (equivalent to their tidal disruption rate for black holes in the small to medium mass range) and the eccentricity distribution of these stars. Our simulations vary not only the particle number, but disc model (two models examined), spatial resolution at the centre (characterised by the numerical accretion radius) and softening length. The large parameter range and physically realistic modelling allow us for the first time to confidently extrapolate these results to real galactic centres. While in a real galactic centre both particle number and accretion radius differ by a few orders of magnitude from our models, which are constrained by numerical capability, we find that the stellar accretion rate converges for models with N > 32k. The eccentricity distribution of accreted stars, however, does not converge. We find that there are two competing effects at work when improving the resolution: larger particle number leads to a smaller fraction of stars accreted on nearly-circular orbits, while higher spatial resolution increases this fraction. We scale our simulations to some nearby galaxies and find that the expected boost in stellar accretion (or tidal disruption, which could be observed as X-ray flares) in the presence of a gas disc is about a factor of 10. Even with this boost, the accretion of mass from stars is still a factor of ~ 100 slower than the accretion of gas from the disc. Thus, it seems accretion of stars is not a major contributor to black hole mass growth.

description: When a charged particle travels across the vacuum chamber of an accelerator, it induces electromagnetic fields, which are left mainly behind the generating particle. These electromagnetic fields act back on the beam and influence its motion. Such an interaction of the beam with its surro undings results in beam energy losses, alters the shape of the bunches, and shifts the betatron and synchrotron frequencies. At high beam current the fields can even lead to instabilities, thus limiting the performance of the accelerator in terms of beam quality and current intensity. We discuss in this lecture the general features of the electromagnetic fields, introducing the concepts of wakefields and giving a few simple examples in cylindrical geometry. We then show the effect of the wakefields on the dynamics of a beam in a linac, dealing in particular with the beam breakup instability and how to cure it.

description: Research on transition to higher education and young people with disabilities has increased in recent years. However, there is still limited understanding of transition issues and how digital technologies, such as social media and mobile devices, are used by this group of students to manage these issues. This article presents the findings of an empirical study that addressed this matter based on young people’s views and experiences. The qualitative study was conducted in the context of a group of students with vision impairments transitioning to a New Zealand university. The findings draw from observations, a researcher diary, focus groups, individual interviews, and data from social media. The study shows that, like their non-disabled peers, the students actively engaged with interactive and collaborative digital technologies to make sense, individually and collectively, of different transition issues before, during and after the first academic trimester of their university journey.

description: Access to high-quality and continuous education is a fundamental right for all children, including those affected by conflict and protracted crises. Yet despite ongoing efforts, significant barriers to access, quality and continuity of education remain. In this paper, we apply a conceptual framework recently developed as part of the Education Research in Conflict and Protracted Crises (ERICC) project to carry out a systematic review of evidence about the state of education in Cox’s Bazar, Bangladesh, where education delivery to conflict-affected Rohingya communities remains particularly challenging. Following an ERICC-informed analysis of 127 studies, we identify critical knowledge gaps in existing evidence: there is little to no evidence for what works; data on access, and on the quality and continuity of education are lacking; and few studies provide analysis at policy systems level. This is a significant concern since these gaps limit the ability of existing evidence to ensure that the new policy shift to the Myanmar curriculum delivers high-quality education in Cox’s Bazar. The implications of these findings provide national stakeholders, development agencies, and their partners with a comprehensive understanding of the analytical work taking place on the ground.

description: We study a variant of the quantum approximate optimization algorithm [ E. Farhi, J. Goldstone, and S. Gutmann, arXiv:1411.4028] with slightly different parametrization and different objective: rather than looking for a state which approximately solves an optimization problem, our goal is to find a quantum algorithm that, given an instance of MAX-2-SAT, will produce a state with high overlap with the optimal state. Using a machine learning approach, we chose a "training set" of instances and optimized the parameters to produce large overlap for the training set. We then tested these optimized parameters on a larger instance set. As a training set, we used a subset of the hard instances studied by E. Crosson, E. Farhi, C. Yen-Yu Lin, H.-H. Lin, and P. Shor (CFLLS) [arXiv:1401.7320]. When tested on the full set, the parameters that we find produce significantly larger overlap than the optimized annealing times of CFLLS. Testing on other random instances from $20$ to $28$ bits continues to show improvement over annealing, with the improvement being most notable on the hardest instances. Further tests on instances of MAX-3-SAT also showed improvement on the hardest instances. This algorithm may be a possible application for near-term quantum computers with limited coherence times.

On this occasion, we give a brief overview of his main scientific achievements in the field of quantum plasmas, complemented by some biographical background of his research and teaching environment at Rostock University. Kelbg's main achievement is the derivation of a regularized quantum pair potential. We demonstrate that it is still of high relevance for molecular dynamics and quantum Monte Carlo simulations of dense plasmas.

description: This is the third paper in a series describing the spectroscopic properties of a sample of 39 AGN at $z \sim 1.5$, selected to cover a large range in black hole mass ($M_{BH}$) and Eddington ratio ($L/L_{Edd}$). In this paper, we continue the analysis of the VLT/X-shooter observations of our sample with the addition of 9 new sources. We use an improved Bayesian procedure, which takes into account intrinsic reddening, and improved $M_{BH}$ estimates, to fit thin accretion disc (AD) models to the observed spectra and constrain the spin parameter ($a_*$) of the central black holes. We can fit 37 out of 39 AGN with the thin AD model, and for those with satisfactory fits, we obtain constraints on the spin parameter of the BHs, with the constraints becoming generally less well defined with decreasing BH mass. Our spin parameter estimates range from $\sim$$-$0.6 to maximum spin for our sample, and our results are consistent with the "spin-up" scenario of BH spin evolution. We also discuss how the results of our analysis vary with the inclusion of non-simultaneous GALEX photometry in our thin AD fitting. Simultaneous spectra covering the rest-frame optical through far-UV are necessary to definitively test the thin AD theory and obtain the best constraints on the spin parameter.

description: In der stationären Kinder- und Jugendhilfe wird der Umgang zwischen Kindern und ihren Eltern oftmals aus kindeswohlbezogenen Gründen an Bestimmungen wie eine Begleitung oder zeitliche oder räumliche Einschränkungen geknüpft. Solche Anordnungen können mithilfe digitaler Medien wie Smartphones immer einfacher umgangen werden. Dieses Phänomen hat in wissenschaftlichen Untersuchungen bislang keine Beachtung gefunden, obgleich die Vermutung naheliegt, dass es negative Auswirkungen für die Klientel und Herausforderungen für die Fachkräfte bedeutet. Das Ziel der Bachelorthesis liegt darin herauszufinden, wie sich die Schnittstelle zwischen digitalen Medien und Umgangsrecht in der Praxis verhält. Um der Forschungsfrage "Welche Bedeutung haben kommunikative Entgrenzungseffekte durch digitale Medien für die Umsetzung von Umgangsbestimmungen und die Praxis von Fachkräften in der stationären Kinder- und Jugendhilfe?" nachzugehen, wurde ein Experteninterview durchgeführt. Dieses wurde mithilfe der Qualitativen Inhaltsanalyse ausgewertet und unter anderem durch John Bowlbys Bindungstheorie gestützt und interpretiert. Zu den zentralen Ergebnissen gehört, dass die unerlaubten Umgangskontakte erhebliche Risiken für die Kinder, die Eltern-Kind-Beziehung sowie die Praxis Sozialer Arbeit bergen. Die Untersuchung zeigt, dass die Ziele der Umgangsbestimmungen kaum erreicht werden können und die Hilfeeinrichtungen ihren Schutzraum verlieren. Zudem wird deutlich, dass Fachkräften kaum Handlungsleitlinien vorliegen und sie den unerlaubten Kontakt nicht verhindern, sondern nur bestmöglich mit den Folgen umgehen können. Dies führt einerseits zu einer Machtlosigkeit auf Seiten der Fachkräfte und andererseits zu einer zunehmenden Wirkungslosigkeit bei der Umsetzung von Umgangsbestimmungen. Die Soziale Arbeit ist angehalten, diese Problematik im Fachdiskurs präsent zu machen, sodass ein bedachter Umgang mit ihr möglich wird, sowie die Theorie und Praxis an diese neuen und veränderten Umstände anzupassen.

description: Cox’s Bazar in Bangladesh remains one of the world’s most difficult places for education delivery in conflict and protracted crises, as Rohingya communities who fled state violence in Myanmar face multiple barriers to education access, quality, and continuity under a coherent system. Despite this situation, there is a critical lack of systematic evidence on the development, implementation, and impact of education interventions among host and Rohingya communities. Informed by the ERICC Conceptual Framework and consultations with local stakeholders, our research agenda tackles the problem by developing a series of studies on three key aspects of education in Cox’s Bazar: ongoing responses to the recently introduced Myanmar curriculum, the current role of madrasas and their potential as partners for education interventions, and an analysis on continuing education for girls and older adolescents. These studies will collect novel data on little-understood areas of education in host and refugee communities, fill knowledge gaps at policy system and local system levels, and provide much-needed insights to inform policy and research on education under conflict and protracted crises in Cox’s Bazar and beyond.
Identification of conserved moieties in metabolic networks by graph theoretical analysis of atom transition networks

description: Conserved moieties are groups of atoms that remain intact in all reactions of a metabolic network. Identification of conserved moieties gives insight into the structure and function of metabolic networks and facilitates metabolic modelling. All moiety conservation relations can be represented as nonnegative integer vectors in the left null space of the stoichiometric matrix corresponding to a biochemical network. Algorithms exist to compute such vectors based only on reaction stoichiometry but their computational complexity has limited their application to relatively small metabolic networks. Moreover, the vectors returned by existing algorithms do not, in general, represent conservation of a specific moiety with a defined atomic structure. Here, we show that identification of conserved moieties requires data on reaction atom mappings in addition to stoichiometry. We present a novel method to identify conserved moieties in metabolic networks by graph theoretical analysis of their underlying atom transition networks. Our method returns the exact group of atoms belonging to each conserved moiety as well as the corresponding vector in the left null space of the stoichiometric matrix. It can be implemented as a pipeline of polynomial time algorithms. Our implementation completes in under five minutes on a metabolic network with more than 4,000 mass balanced reactions. The scalability of the method enables extension of existing applications for moiety conservation relations to genome-scale metabolic networks. We also give examples of new applications made possible by elucidating the atomic structure of conserved moieties.

(Figure 2, a–e)
 Closed pileus initially ellipsoid, 13–18 × 9–13 mm, ochraceous brown to gray-brown, becoming lighter towards the margin, naked, with several setose pileocystidia, hardly observable in stereomicroscopy. Expanded pileus campanulate, 25–27 mm in diameter, dark gray to whitish. Veil absent. Lamellae free, rarely adnexed, initially whitish, finally dark gray to black with the maturation of basidia and basidiospores. Stipe central, cylindrical, hollow, pubescent, straight or crooked, whitish, 25–50 mm long, 1.5–2 mm in diameter. Ring absent. Volva absent. Pileocystidia abundant, setose, 75–110 μm, lageniform, decreasing considerably in diameter towards the apex, about 10–15 μm in diameter at the proximal end, tapering to 1–2 μm near the distal end, hyaline, smooth, thin-walled. Cheilocystidia not observed. Pleurocystidia not observed. Basidia 4-spored, club-shaped, surrounded by hyphidial elements. Basidiospores mitriform in frontal view, cylindrical to ellipsoid in side view, flat, dark reddish brown, 7.2–8.5 × 6–7.5 μm, thick-walled, with a central germ pore.
 Material examined: — BRAZIL. Pernambuco, Instituto Agronômico de Pernambuco (IPA), Serra Talhada, on horse dung, 04. Jun 2012, R.F. R. Melo (URM86793!); Universidade Federal Rural de Pernambuco (UFRPE), Recife, on cattle dung, 19. Jun 2012, R.F. R. Melo (URM86794 a!, 86794b!).
 Distribution: —Europe (Netherlands, Switzerland). This is the first record from Brazil.
 Notes: — Coprinellus angulatus, a rare species on herbivore dung, has small basidiomata forming directly on incubated dung, with a thinner stipe than the specimens described from soil or plant material. It can be easily distinguished by the combination of the following characters: naked pileus, with setose pileocystida exceeding 100 mm in length and mitriform basidiospores in frontal view.

description: Action languages have emerged as an important field of Knowledge Representation for reasoning about change and causality in dynamic domains. This article presents Cerbere, a production system designed to perform online causal, temporal and epistemic reasoning based on the Event Calculus. The framework implements the declarative semantics of the underlying logic theories in a forward-chaining rule-based reasoning system, coupling the high expressiveness of its formalisms with the efficiency of rule-based systems. To illustrate its applicability, we present both the modeling of benchmark problems in the field, as well as its utilization in the challenging domain of smart spaces. A hybrid framework that combines logic-based with probabilistic reasoning has been developed, that aims to accommodate activity recognition and monitoring tasks in smart spaces.

High-cadence spectroscopy of M-dwarfs. I. Analysis of systematic effects in HARPS-N line profile measurements on the bright binary GJ 725A+B

description: Understanding the sources of instrumental systematic noise is a must to improve the design of future spectrographs. In this study, we alternated observations of the well-suited pair of M-stars GJ 725A+B to delve into the sub-night HARPS-N response. Besides the possible presence of a low-mass planet orbiting GJ 725B, our observations reveal changes in the spectral energy distribution (SED) correlated with measurements of the width of the instrumental line profile and, to a lower degree, with the Doppler measurements. To study the origin of these effects, we searched for correlations among several quantities defined and measured on the spectra and on the acquisition images. We find that the changes in apparent SED are very likely related to flux losses at the fibre input. Further tests indicate that such flux losses do not seriously affect the shape of the instrumental point spread function of HARPS-N, but identify an inefficient fitting of the continuum as the most likely source of the systematic variability observed in the FWHM. This index, accounting for the HARPS-N cross-correlation profiles width, is often used to decorrelate Doppler time-series. We show that the Doppler measurement obtained by a parametric least-squares fitting of the spectrum accounting for continuum variability is insensitive to changes in the slope of the SED, suggesting that forward modeling techniques to measure moments of the line profile are the optimal way to achieve higher accuracy. Remaining residual variability at ~1 m/s suggests that for M-stars Doppler surveys the current noise floor still has an instrumental origin.

description: We analyzed deep $Chandra$ ACIS-I exposures of the cluster-scale X-ray halo surrounding the radio source 4C+37.11. This remarkable system hosts the closest resolved pair of super-massive black hole and an exceptionally luminous elliptical galaxy, the likely product of a series of past mergers. We characterize the halo with $r_{500} = 0.95$ Mpc, $M_{500} = (2.5 \pm 0.2) \times 10^{14} \ M_{\rm{\odot}}$, $ kT = 4.6\pm 0.2$ keV, and a gas mass of $M_{\rm g,500} = (2.2 \pm 0.1) \times 10^{13} M_\odot$. The gas mass fraction within $r_{500}$ is $f_{\rm g} = 0.09 \pm 0.01$. The entropy profile shows large non-gravitational heating in the central regions. We see several surface brightness jumps, associated with substantial temperature and density changes, but approximate pressure equilibrium, implying that these are sloshing structures driven by a recent merger. A residual intensity image shows core spiral structure closely matching that seen for the Perseus cluster, although at $z=0.055$ the spiral pattern is less distinct. We infer the most recent merger occurred $1-2$ Gyr ago and that the event that brought the two observed super-massive black holes to the system core is even older. Under that interpretation, this black hole binary pair has, unusually, remained at pc-scale separation for more than 2 Gyr.

On the Active Region Bright Grains Observed in the Transition Region Imaging Channels of IRIS

description: The Interface Region Imaging Spectrograph (IRIS) provides spectroscopy and narrow band slit-jaw (SJI) imaging of the solar chromosphere and transition region at unprecedented spatial and temporal resolution. Combined with high-resolution context spectral imaging of the photosphere and chromosphere as provided by the Swedish 1-m Solar Telescope (SST), we can now effectively trace dynamic phenomena through large parts of the solar atmosphere in both space and time. IRIS SJI 1400 images from active regions, which primarily sample the transition region with the Si IV 1394 and 1403 Å lines, reveal ubiquitous bright "grains" which are short-lived (2-5 min) bright roundish small patches of sizes 0.5-1.7" that generally move limbward with velocities up to about 30 km s$^{-1}$. In this paper we show that many bright grains are the result of chromospheric shocks impacting the transition region. These shocks are associated with dynamic fibrils (DFs), most commonly observed in Hα. We find that the grains show strongest emission in the ascending phase of the DF, that the emission is strongest towards the top of the DF and that the grains correspond to a blueshift and broadening of the Si IV lines. We note that the SJI 1400 grains can also be observed in the SJI 1330 channel which is dominated by C II lines. Our observations show that a significant part of the active region transition region dynamics is driven from the chromosphere below rather than from coronal activity above. We conclude that the shocks that drive DFs also play an important role in the heating of the upper chromosphere and lower transition region.

Generation of mechanical force by grafted polyelectrolytes in an electric field

description: We study theoretically and by means of molecular dynamics (MD) simulations the generation of mechanical force by grafted polyelectrolytes in an external electric field, which favors its adsorption on the grafting plane. The force arises in deformable bodies linked to the free end of the chain. Varying the field, one controls the length of the non-adsorbed part of the chain and hence the deformation of the target body, i.e., the arising force too. We consider target bodies with a linear force-deformation relation and with a Hertzian one. While the first relation models a coiled Gaussian chain, the second one describes the force response of a squeezed colloidal particle. The theoretical dependencies of generated force and compression of the target body on applied field agree very well with the results of MD simulations. The analyzed phenomenon may play an important role in a future nano-machinery, e.g. it may be used to design nano-vices to fix nano-sized objects.

description: The electronic structure of Mn doped GaAs and GaN have been examined within a multiband Hubbard model. By virtue of the positioning of the Mn d states, Mn doped GaAs is found to belong to the p-d metal regime of the Zaanen-Sawatzky-Allen phase diagram and its variants while Mn doping in GaN belongs to the covalent insulator regime. Their location in the phase diagram also determines how they would behave under quantum confinement which would increase the charge transfer energy. The ferromagnetic stability of Mn doped GaAs, we find, increases with confinement therefore providing a route to higher ferromagnetic transition temperatures.
