Ist die EWU ein Modell für eine EU der zwei Geschwindigkeiten?

Die schwierigen Beratungen zu dem auf dem EU-Gipfel des Europäischen Rates im Juni beschlossenen Reformvertrag haben einmal mehr die Frage nach einer Europäischen Union der verschiedenen Geschwindigkeiten aufgeworfen. Entwickelt sich die EU bereits in diese Richtung und was wären die Vor- und Nachteile? Ist die Währungsunion dafür ein Modell? Bietet der EU-Reformvertrag unterschiedliche Integrationsoptionen? --

Magyar orvostanhallgatók angol nyelvi kommunikációs hajlandóságának fejlesztése szaknyelvi órákon

Tanulmányunk egy kvalitatív, feltáró jellegű kutatás keretében írja le, hogy milyen benyomásaik voltak a magyar orvostanhallgatóknak, mialatt kortárs oktatássegítőkkel orvosbeteg szerepjátékokban vettek részt angol orvosi szaknyelvi órákon. A kortárs oktatássegítők, demonstrátorok, a Pécsi Tudományegyetem Általános Orvostudományi Kar (PTE ÁOK) angol nyelvű programjának nemzetközi hallgatói voltak. Elsődleges célunk a magyar hallgatók angol nyelvi kommunikációs hajlandóságának fejlesztése volt a szaknyelvi órákon. Egy motiválóbb és természetesebb nyelvtanulási környezetet kívántunk biztosítani, amelyben a célnyelv volt a résztvevő tanulók közös nyelve. Ezen túlmenően arra is törekedtünk, hogy javítsuk a résztvevők interkulturális kompetenciáját egy olyan platform biztosításával, ahol az Általános Orvostudományi Kar magyar és nemzetközi hallgatói találkozhatnak, megismerkedhetnek, és együtt dolgozhatnak. A szemeszter végén a résztvevő magyar hallgatók véleményét félig strukturált, fókuszcsoportos interjú keretében kérdeztük meg. Az adatokat tematikusan elemeztük, és az eredmények azt mutatták, hogy a magyar orvostanhallgatók lelkesek és motiváltak voltak a szerepjátékok során, nőtt az angol nyelvi kommunikációs hajlandóságuk és ezzel együtt az órai teljesítményük is. Az interjú eredményei arra is rámutattak, hogy a közös szerepjátékkal sikerült közelebb hozni a magyar és a külföldi diákoka

Search for eccentric black hole coalescences during the third observing run of LIGO and Virgo

Despite the growing number of confident binary black hole coalescences observed through gravitational waves so far, the astrophysical origin of these binaries remains uncertain. Orbital eccentricity is one of the clearest tracers of binary formation channels. Identifying binary eccentricity, however, remains challenging due to the limited availability of gravitational waveforms that include effects of eccentricity. Here, we present observational results for a waveform-independent search sensitive to eccentric black hole coalescences, covering the third observing run (O3) of the LIGO and Virgo detectors. We identified no new high-significance candidates beyond those that were already identified with searches focusing on quasi-circular binaries. We determine the sensitivity of our search to high-mass (total mass M>70 M⊙) binaries covering eccentricities up to 0.3 at 15 Hz orbital frequency, and use this to compare model predictions to search results. Assuming all detections are indeed quasi-circular, for our fiducial population model, we place an upper limit for the merger rate density of high-mass binaries with eccentricities 0<e≤0.3 at 0.33 Gpc−3 yr−1 at 90\% confidence level

Ultralight vector dark matter search using data from the KAGRA O3GK run

Among the various candidates for dark matter (DM), ultralight vector DM can be probed by laser interferometric gravitational wave detectors through the measurement of oscillating length changes in the arm cavities. In this context, KAGRA has a unique feature due to differing compositions of its mirrors, enhancing the signal of vector DM in the length change in the auxiliary channels. Here we present the result of a search for U(1)B−L gauge boson DM using the KAGRA data from auxiliary length channels during the first joint observation run together with GEO600. By applying our search pipeline, which takes into account the stochastic nature of ultralight DM, upper bounds on the coupling strength between the U(1)B−L gauge boson and ordinary matter are obtained for a range of DM masses. While our constraints are less stringent than those derived from previous experiments, this study demonstrates the applicability of our method to the lower-mass vector DM search, which is made difficult in this measurement by the short observation time compared to the auto-correlation time scale of DM

Hyperlog: A Graph-Based System for Database Browsing, Querying and Update

Hyperlog is a declarative, graph-based language that supports database querying and update. It visualises schema information, data, and query output as sets of nested graphs, which can be stored, browsed and queried in a uniform way. Thus, the user need only be familiar with a very small set of syntactic constructs. Hyperlog queries consist of a set of graphs that are matched against the database. Database updates are supported by means of programs consisting of a set of rules. This paper discusses the formulation, evaluation, expressiveness and optimisation of Hyperlog queries and programs. We also describe a prototype implementation of the language, and we compare and contrast our approach with work in a number of related areas, including visual database languages, graph-based data models, database update languages and production rule systems. Index terms: database query languages, database update languages, visual query languages, database browsing, hypernodes. 1 Introduction Vis..

Predictability of ab-interno trabeculectomy success in the subsequent eye: A contralateral eye comparison study

Background To determine whether the outcome of the first eye may serve as a predictor for intraocular pressure (IOP)-lowering effectiveness in the second eye following bilateral ab interno trabeculectomy. Methods This retrospective single-centre study included 168 eyes from 84 participants, who underwent combined Trabectome surgery with phacoemulsification cataract surgery in a hospital setting. The clinical endpoint was defined as either 'success' or 'failure' based on four separate scores at the longest follow-up time point: IOP at follow-up 20%; IOP = 40% (Score C); and the sole absence of re-surgery according to the discretion of the surgeon (Score D). Results No significant difference was observed between the outcomes of first and second eyes. The frequency of success in the second eye after effective surgery in the first eye significantly exceeded that after prior failure. Within our analysis, the probability calculations determined a 75% chance of success following prior success for Score A. If surgery in the first eye failed, the chance of success in the subsequent eye was 37%. The corresponding probabilities were 79% and 32% for Score B, 56% and 9% for Score C, and 99% and 50% for Score D. Conclusion The results of our study offer a useful tool to assess the success of subsequent eye surgeries based on the outcome in the initial eye, owing to the high predictive potential
