description: The emergence of the seeds of cosmic structure, from a perfect isotropic and homogeneous Universe, has not been clearly explained by the standard version of inflationary models as the dynamics involved preserve the homogeneity and isotropy at all times. A proposal that attempts to deal with this problem, by introducing "the self-induced collapse hypothesis," has been introduced by D. Sudarsky and collaborators in previous papers. In all these works, the collapse of the wave function of the inflaton mode is restricted to occur during the inflationary period. In this paper, we analyse the possibility that the collapse happens during the radiation era. A viable model can be constructed under the condition that the inflaton field variable must be affected by the collapse while the momentum variable can or cannot be affected. Another condition to be fulfilled is that the time of collapse must be independent of $k$. However, when comparing with recent observational data, the predictions of the model cannot be distinguished from the ones provided by the standard inflationary scenario. The main reason for this arises from the requirement that primordial power spectrum obtained for the radiation era matches the amplitude of scalar fluctuations consistent with the latest CMB observations. This latter constraint results in a limit on the possible times of collapse and ensures that the contribution of the inflaton field to the energy-momentum tensor is negligible compared to the contribution of the radiation fields.

description: (Abridged) The birth environment of the Sun will have influenced the conditions in the pre-solar nebula, including the attainable chemical complexity, important for prebiotic chemistry. The formation and distribution of complex organic molecules (COMs) in a disk around a T Tauri star is investigated for two scenarios: (i) an isolated disk, and (ii) a disk irradiated externally by a nearby massive star. The chemistry is calculated along the accretion flow from the outer disk inwards using a comprehensive network. Two simulations are performed, one beginning with complex ices and one with simple ices only. For the isolated disk, COMs are transported without major alteration into the inner disk where they thermally desorb into the gas reaching an abundance representative of the initial assumed ice abundance. For simple ices, COMs efficiently form on grain surfaces under the conditions in the outer disk. Gas-phase COMs are released into the molecular layer via photodesorption. For the irradiated disk, complex ices are also transported inwards; however, they undergo thermal processing caused by the warmer conditions in the irradiated disk which tends to reduce their abundance along the accretion flow. For simple ices, grain-surface chemistry cannot synthesise COMs in the outer disk because the necessary grain-surface radicals, which tend to be particularly volatile, are not sufficiently abundant on the grain surfaces. Gas-phase COMs are formed in the inner region of the irradiated disk via gas-phase chemistry induced by the desorption of strongly bound molecules such as methanol; hence, the abundances are not representative of the initial molecular abundances injected into the outer disk. These results suggest that the composition of comets formed in isolated disks may differ from those formed in externally irradiated disks with the latter composed of more simple ices.

description: In dieser Literaturarbeit befassen sich die Autor*innen Chiara Erni, Eric Waldvogel und Davina Wolfisberg mit der Frage, wie die sozialpädagogische Beratung für Menschen mit kognitiver Beeinträchtigung im stationären Bereich gestärkt werden kann. Um die Fragestellung zu beantworten, wurde eine fachliche und kritische Auseinandersetzung mit der hierfür relevanten Literatur vorgenommen.

Menschen mit kognitiver Beeinträchtigung haben einen unzureichenden Zugang zu Beratungsangeboten. Der Schattenbericht von Inclusion Handicap (2022) und weitere Analysen weisen darauf hin, dass entsprechende Forderungen der UNO-Behindertenrechtskonvention (UNO-BRK) noch nicht ausreichend umgesetzt wurden.

Menschen mit einer kognitiven Beeinträchtigung haben oft Schwierigkeiten in der verbalen Kommunikation und beim Ausdrücken von Bedürfnissen. Die SEED-Diagnostik hilft, die Beratung auf individuelle Bedürfnisse abzustimmen. Auf struktureller Ebene braucht es einen offenen Diskurs über Machtstrukturen, denn Menschen mit einer Beeinträchtigung sind besonders häufig von Unterdrückung und Gewalt betroffen. Für die Beratung von Menschen mit einer kognitiven Beeinträchtigung können unterschiedliche Beratungsmethoden und Hilfsmittel der Unterstützten Kommunikation (UK) angewendet werden. Diese müssen individuell auf die Ratsuchenden angepasst werden.

 Die Autor*innen empfehlen eine Implementierung von Beratungsangeboten im Leistungsauftrag, um passende Unterstützungsangebote zu garantieren. Die Institutionen sollen passende Beratungskonzepte erarbeiten, die ihren Klient*innen Selbstbestimmung und Teilhabe gewährleisten.

description: Evanescent light excitation is widely used in super-resolution fluorescence microscopy to confine light and reduce background noise. Herein we propose a method of exploiting evanescent light in the context of emission. When a fluorophore is located in close proximity to a medium with a higher refractive index, its near-field component is converted into light that propagates beyond the critical angle. This so-called Supercritical Angle Fluorescence (SAF) can be captured using a hig-NA objective and used to determine the axial position of the fluorophore with nanometer precision. We introduce a new technique for 3D nanoscopy that combines direct STochastic Optical Reconstruction Microscopy (dSTORM) imaging with dedicated detection of SAF emission. We demonstrate that our approach of a Direct Optical Nanoscopy with Axially Localized Detection (DONALD) yields a typical isotropic 3D localization precision of 20 nm.

description: We perform cosmological hydrodynamics simulations with non-equilibrium primordial chemistry to obtain 59 minihalos that host first stars. The obtained minihalos are used as initial conditions of local three dimensional radiation hydrodynamics simulations to investigate the formation of the first stars. We find two-thirds of the minihalos host multiple stars, while the rest of them have single stars. The mass of the stars found in our simulations are in the range of 1 Msun \la M \la 300 Msun, peaking at several x 10 Msun. Most of the very massive stars of \ga 140 Msun are born as single stars, although not all of the single stars are very massive. We also find a few stars of \la 1 Msun that are kicked by the gravitational three body interactions to the position distant from the center of mass. The frequency that a star forming minihalo contains a binary system is \sim 50%. We also investigate the abundance pattern of the stellar remnants by summing up the contributions from the first stars in the simulations. Consequently, the pattern is compatible with that of the low metallicity Damped Lyman-alpha systems or the Extremely Metal Poor (EMP) stars, if the mass spectrum obtained in our experiment is shifted to the low mass side by 0.2 dex. If we consider the case that an EMP star is born in the remnant of the individual minihalo without mixing with others, the chemical signature of the pair instability supernova is more prominent, because most of them are born as single stars.

description: What are Type II-Linear supernovae (SNe II-L)? This class, which has been ill defined for decades, now receives significant attention -- both theoretically, in order to understand what happens to stars in the ~15-25Mo range, and observationally, with two independent studies suggesting that they cannot be cleanly separated photometrically from the regular hydrogen-rich SNe II-P characterised by a marked plateau in their light curve. Here, we analyze the multi-band light curves and extensive spectroscopic coverage of a sample of 35 SNe II and find that 11 of them could be SNe II-L. The spectra of these SNe are hydrogen deficient, typically have shallow Halpha absorption, may show indirect signs of helium via strong OI 7774 absorption, and have faster line velocities consistent with a thin hydrogen shell. The light curves can be mostly differentiated from those of the regular, hydrogen-rich SNe II-P by their steeper decline rates and higher luminosity, and we propose as a defining photometric characteristic the decline in the V band: SNe II-L seem to decline by more than 0.5 mag from peak brightness by day 50 after explosion. Using our sample we provide template light curves for SNe II-L and II-P in 4 photometric bands.

description: The Cross-Domain Interoperability Framework (CDIF) is designed to support FAIR implementation by establishing a ‘lingua franca’, based on existing standards and technologies to support interoperability, in both human- and machine-actionable fashion. CDIF is a set of implementation recommendations, based on profiles of common, domain-neutral metadata standards which are aligned to work together to support core functions required by FAIR.

This report presents a core set of five CDIF profiles, which address the most important functions for cross-domain FAIR implementation. 

Discovery (discovery of data and metadata resources)

Data access (specifically, machine-actionable descriptions of access conditions and permitted use)

Controlled vocabularies (good practices for the publication of controlled vocabularies and semantic artefacts)

Data integration (description of the structural and semantic aspects of data to make it integration-ready)

Universals (the description of ‘universal’ elements, time, geography, and units of measurement).

Each of these profiles is supported by specific recommendations, including the set of metadata fields in specific standards to use, and the method of implementation to be employed for machine-level interoperability.

A further set of topics is examined, establishing the priorities for further work. These include:

Provenance (the description of provenance and processing)

Context (the description of ‘context’ in the form of dependencies between fields within the data and a description of the research setting)

Perspectives on AI (discussing the impacts of AI and the role that metadata can play)

Packaging (the creation of archival and dissemination packages) 

Additional Data Formats (support for some of the data formats not fully supported in the initial release, such as NetCDF, Parquet, and HDF5). 

In each of these topics, current discussions are documented, and considerations for further work are provided.

description: Quantum chaotic interacting N-particle systems are assumed to show fast and irreversible spreading of quantum information on short (Ehrenfest) time scales ∼logN. Here we show that, near criticality, certain many-body systems exhibit fast initial scrambling, followed subsequently by oscillatory behavior between reentrant localization and delocalization of information in Hilbert space. Specifically, we consider quantum critical bosonic systems with attractive contact interaction that, despite being integrable, exhibit locally unstable dynamics in the corresponding many-body phase space of the large-N limit. Semiclassical quantization of the latter accounts for many-body correlations in excellent agreement with simulations. Most notably, it predicts an asymptotically constant local level spacing ℏ/τ, again given by τ∼logN. This governs the long-time behavior of out-of-time-order correlators that feature quasi-periodic recurrences indicating reversibility.

Die Ergebnisse zeigen, dass die Umstellungen von Lehre und Prüfungen während der Digitalsemester größtenteils als erfolgreich eingeschätzt werden. Zu einem bedeutenden Digitalisierungsschub anderer Bereiche der Hochschulen kam es aber nur bedingt. Hochschulen sollten ihr Lehrangebot konsequent ausbauen und in Zukunft auch nach der Coronapandemie eine geeignete Kombination aus Präsenz- und Onlineformaten anbieten. Ferner müssen Hochschulen ihre Digitalisierungsstrategien konsequent weiterentwickeln, Verantwortlichkeiten und Rollen klar definieren und Experimentierräume auch für Kooperationen über Hochschulgrenzen hinweg schaffen. Die Mittelausstattung der Hochschulen für die Digitalisierung muss dabei langfristig ausgelegt sein, um Planungssicherheit zu schaffen.

description: Stellar activity can be a source of radial velocity (RV) noise and can reproduce periodic RV variations similar to those produced by an exoplanet. We present the vigorous activity cycle in the primary of the visual binary HD200466, a system made of two almost identical solar-type stars with an apparent separation of 4.6 arcsec at a distance of 44+/-2 pc. High precision RV over more than a decade, adaptive optics (AO) images, and abundances have been obtained for both components. A linear trend in the RV is found for the secondary. We assumed that it is due to the binary orbit and once coupled with the astrometric data, it strongly constrains the orbital solution of the binary at high eccentricities (e~0.85) and quite small periastron of ~21 AU. If this orbital motion is subtracted from the primary radial velocity curve, a highly significant (false alarm probability <0.1%) period of about 1300 d is obtained, suggesting in a first analysis the presence of a giant planet, but it turned out to be due to the stellar activity cycle. Since our spectra do not include the Ca~II resonance lines, we measured a chromospheric activity indicator based on the Halpha line to study the correlation between activity cycles and long-term activity variations. While the bisector analysis of the line profile does not show a clear indication of activity, the correlation between the Halpha line indicator and the RV measurements identify the presence of a strong activity cycle.

description: Psi-calculi is a parametric framework for extensions of the pi-calculus with data terms and arbitrary logics. In this framework there is no direct way to represent action priorities, where an action can execute only if all other enabled actions have lower priority. We here demonstrate that the psi-calculi parameters can be chosen such that the effect of action priorities can be encoded. To accomplish this we define an extension of psi-calculi with action priorities, and show that for every calculus in the extended framework there is a corresponding ordinary psi-calculus, without priorities, and a translation between them that satisfies strong operational correspondence. This is a significantly stronger result than for most encodings between process calculi in the literature. We also formally prove in Nominal Isabelle that the standard congruence and structural laws about strong bisimulation hold in psi-calculi extended with priorities.

description: In Low Earth Orbit (LEO) mega constellations, there are relevant use cases, such as inference based on satellite imaging, in which a large number of satellites collaboratively train a machine learning model without sharing their local datasets. To address this problem, we propose a new set of algorithms based on Federated learning (FL), including a novel asynchronous FL procedure based on FedAvg that exhibits better robustness against heterogeneous scenarios than the state-of-the-art. Extensive numerical evaluations based on MNIST and CIFAR-10 datasets highlight the fast convergence speed and excellent asymptotic test accuracy of the proposed method.

description: We have determined the Galactic rotation parameters and the solar Galactocentric distance R_0 by simultaneously solving Bottlinger's kinematic equations using data on masers with known line-of-sight velocities and highly accurate trigonometric parallaxes and proper motions measured by VLBI. Our sample includes 73 masers spanning the range of Galactocentric distances from 3 to 14 kpc. The solutions found are Omega_0 = 28.86 +/- 0.45 km/s/kpc, Omega'_0 = -3.96 +/- 0.09 km/s/kpc^2, Omega"_0 =0.790 +/- 0.027 km/s/kpc^3, and R_0=8.3 +/- 0.2 kpc.In this case, the linear rotation velocity at the solar distance Ro is V_0=241 +/- 7 km/s. Note that we have obtained the Ro estimate, which is of greatest interest, from masers for the first time; it is in good agreement with the most recent estimates and even surpasses them in accuracy.

description: Die Bachelorarbeit Bildung für nachhaltige Entwicklung in der Schweiz – Ein Argumentarium zur Integration in den Auftrag der Sozialen Arbeit von Leonie Flückiger und Adina Nussbaumer stellt sich den Fragen, warum Bildung für nachhaltige Entwicklung [BNE] auch Aufgabe der Sozialen Arbeit ist und in welchen Handlungsfeldern der Sozialen Arbeit sie eingesetzt werden kann. Das Ziel der Arbeit ist die Schaffung eines Argumentariums, welches Professionelle verwenden können, um die Implikation von BNE in ihren Berufsalltag zu begründen. Gestartet wird mit einem Einstieg ins Thema BNE mittels Definition der Kernbegriffe. Gefolgt von einer Analyse zur Bedeutung und den Möglichkeiten, welche der non-formale und informelle Bildungskontext bietet. Anschliessend wird im weiteren Verlauf der Arbeit durch einen Vergleich von BNE mit der Lebensweltorientierung nach Thiersch, der Habitustheorie nach Bourdieu, der Systemtheorie nach Luhmann, den Menschenrechten und dem Berufskodex festgestellt, dass BNE viele Ähnlichkeiten in der Arbeitsweise und der Wertehaltung zur Sozialen Arbeit aufweist. Aus diesem Grund wird konkludiert, dass eine Integration in den Berufsalltag Sozialarbeitender gut möglich ist. Anschliessend wird am Beispiel von drei Handlungsfeldern der Sozialen Arbeit aufgezeigt, wie BNE von Sozialarbeitenden angewendet werden könnte. Aus den Erkenntnissen wird konkludiert, dass BNE in allen Handlungsfeldern der Sozialen Arbeit eingesetzt werden kann. Zum Abschluss folgt das Argumentarium, welches nationale, internationale, methodische und rechtliche Aspekte beinhaltet sowie ein Ausblick für die mögliche weitere Behandlung des Themas.

description: Strong electron interactions in solids increase effective mass, and shrink the electronic bands [1]. One of the most unique and robust experimental facts about iron-based superconductors [2-4] is the renormalization of the conduction band by factor of 3 near the Fermi level [5-9]. Obviously related to superconductivity, this unusual behaviour remains unexplained. Here, by studying the momentum-resolved spectrum of the whole valence band in a representative material, we show that this phenomenon originates from electronic interaction on a much larger energy scale. We observe an abrupt depletion of the spectral weight in the middle of the Fe $3d$ band, which is accompanied by a drastic increase of the scattering rate. Remarkably, all spectral anomalies including the low-energy renormalization can be explained by coupling to excitations, strongly peaked at about 0.5 eV. Such high-energy interaction distinguishes all unconventional superconductors from common metals.

Self-organized electronic superlattices in layered materials

description: We show that in layered systems with electronic phase separation tendency, the long-range Coulomb interaction can drive the spontaneous formation of unidirectional superlattices of electronic charge in a completely homogeneous crystalline background. In this self-organized electronic heterostructure, the ratio among the number of crystalline planes in the minority and majority electronic phases corresponds to Farey fractions with the superlattice period controlled by the background charge density and the frustrating Coulomb interaction strength. The phase diagram displays Arnold tongues obeying a modified Farey tree hierarchy and a devil's staircase typical of systems with frustration among different scales. We further discuss the competition of these electronic superlattices, recently observed in iron-based superconductors and mixed valence compounds, with in-plane electronically modulated phases.

Matching in the Pi-Calculus

description: We study whether, in the pi-calculus, the match prefix-a conditional operator testing two names for (syntactic) equality-is expressible via the other operators. Previously, Carbone and Maffeis proved that matching is not expressible this way under rather strong requirements (preservation and reflection of observables). Later on, Gorla developed a by now widely-tested set of criteria for encodings that allows much more freedom (e.g. instead of direct translations of observables it allows comparison of calculi with respect to reachability of successful states). In this paper, we offer a considerably stronger separation result on the non-expressibility of matching using only Gorla's relaxed requirements.

A Policy Iteration Approach for Flock Motion Control

description: The flocking motion control is concerned with managing the possible conflicts between local and team objectives of multi-agent systems. The overall control process guides the agents while monitoring the flock-cohesiveness and localization. The underlying mechanisms may degrade due to overlooking the unmodeled uncertainties associated with the flock dynamics and formation. On another side, the efficiencies of the various control designs rely on how quickly they can adapt to different dynamic situations in real-time. An online model-free policy iteration mechanism is developed here to guide a flock of agents to follow an independent command generator over a time-varying graph topology. The strength of connectivity between any two agents or the graph edge weight is decided using a position adjacency dependent function. An online recursive least squares approach is adopted to tune the guidance strategies without knowing the dynamics of the agents or those of the command generator. It is compared with another reinforcement learning approach from the literature which is based on a value iteration technique. The simulation results of the policy iteration mechanism revealed fast learning and convergence behaviors with less computational effort.

description: This paper deals with the thermal performances of roof-mounted radiant barriers. Using dynamic simulations of a mathematical model of a whole test cell including a radiant barrier installed between the roof top and the ceiling, the thermal performance of the roof is calculated. The mean method is more particularly used to assess the thermal resistance of the building component and lead to a value which is compared to the one obtained for a mass insulation product such as polyurethane foam. On a further stage, the thermal mathematical model is replaced by a thermo-aeraulic model which is used to evaluate the thermal resistance of the roof as a function of the airflow rate. The results shows a better performance of the roof in this new configuration, which is widely used in practice. Finally, the mathematical relation between the thermal resistance and the airflow rate is proposed.
INCOME TAX ASSIGNMENT UNDER THE ETHIOPIAN CONSTITUTION : ISSUES TO WORRY ABOUT

Ethiopian Constitution
fiscal federalism
revenue assignment

description: The revenue provisions of the Ethiopian Constitution are striking on a number
 of levels. By and large, the revenue provisions do not evince conformity with
 what the theories of fiscal federalism generally prescribe in the area of
 assignment of revenue powers. In addition, the revenue provisions of the
 Ethiopian Constitution are more detailed than their counterparts elsewhere.
 And, the Ethiopian Constitution departs from the assignment formula set for
 expenditure powers and prescribes a special procedure for assignment of
 ‘undesignated taxes’. These features of the Ethiopian Constitution raise a
 number of questions and concerns. This article uses the income tax assignment
 in the Ethiopian Constitution to highlight some of these questions and
 concerns. There is ample evidence to show that the assignment formula adopted
 by the Constitution, indeed its predecessor - the 1992 law - was motivated by
 the desire to divide the power of taxation over existing taxes in Ethiopia rather
 than to reinvent the wheel. However, there might be a tension between the
 formula the Constitution adopts to assign tax powers and the prescriptions of
 the theories of fiscal federalism. The article explores the implications of this
 assignment.
