description: We study the $2e^-2e^+$ equal-mass charge-neutral four-body system in the adiabatic hyperspherical framework. The lowest few adiabatic potentials are calculated for zero orbital angular momentum, positive parity, and charge conjugation symmetries. Propagating the R-matrix, the low-energy $s$-wave scattering lengths of the singlet-singlet and triplet-triplet spin configurations are calculated. Lastly, we calculate the S-matrix for energies above the ionic threshold to estimate the transition rates between the single ionic fragmentation channel and the lowest few dimer-dimer fragmentation channels.

description: We are merging a large participatory science effort with machine learning to enhance the Hobby-Eberly Telescope Dark Energy Experiment (HETDEX). Our overall goal is to remove false positives, allowing us to use lower signal-to-noise data and sources with low goodness-of-fit. With six million classifications through Dark Energy Explorers, we can confidently determine if a source is not real at over 94% confidence level when classified by at least ten individuals; this confidence level increases for higher signal-to-noise sources. To date, we have only been able to apply this direct analysis to 190,000 sources. The full sample of HETDEX will contain around 2-3M sources, including nearby galaxies ([O II] emitters), distant galaxies (Lyman-alpha emitters or LAEs), false positives, and contamination from instrument issues. We can accommodate this tenfold increase by using machine learning with visually-vetted samples from Dark Energy Explorers. We have already increased by over ten-fold in number of sources that have been visually vetted from our previous pilot study where we only had 14,000 visually vetted LAE candidates. This paper expands on the previous work increasing the visually-vetted sample from 14,000 to 190,000. In addition, using our currently visually-vetted sample, we generate a real or false positive classification for the full candidate sample of 1.2 million LAEs. We currently have approximately 17,000 volunteers from 159 countries around the world. Thus, we are applying participatory or citizen scientist analysis to our full HETDEX dataset, creating a free educational opportunity that requires no prior technical knowledge.

description: Correlated-electron systems support a wealth of magnetic excitations, ranging from conventional spin waves to exotic fractional excitations in low-dimensional or geometrically-frustrated spin systems. Probing such excitations on nanometre length scales is essential for unravelling the underlying physics and developing new spintronic nanodevices. However, no established technique provides real-space, few-nanometre-scale probing of correlated-electron magnetic excitations under ambient conditions. Here we present a solution to this problem using magnetometry based on single nitrogen-vacancy (NV) centres in diamond. We focus on spin-wave excitations in a ferromagnetic microdisc, and demonstrate local, quantitative, and phase-sensitive detection of the spin-wave magnetic field at ~50 nm from the disc. We map the magnetic-field dependence of spin-wave excitations by detecting the associated local reduction in the disc's longitudinal magnetization. In addition, we characterize the spin-noise spectrum by NV-spin relaxometry, finding excellent agreement with a general analytical description of the stray fields produced by spin-spin correlations in a 2D magnetic system. These complementary measurement modalities pave the way towards imaging the local excitations of systems such as ferromagnets and antiferromagnets, skyrmions, atomically assembled quantum magnets, and spin ice.

Zur Chronologie der Spätwerke Johann Sebastian Bachs

description: Die Grundlage für eine genaue Chronologie des Spätwerks von Bach bilden datierte Dokumente, eine detaillierte Untersuchung der Handschrift Bachs aus seinen späteren Jahren sowie die Identifizierung von Wasserzeichen und Handschriften von Kopisten. Auf der Grundlage dieser Kriterien wird die h-Moll-Messe BWV 232 als letzte abgeschlossene Arbeit identifiziert. Die Kunst der Fuge BWV 1080, die bisher der letzten Lebensperiode von Bach zugeordnet war, scheint dagegen bereits zu einem großen Teil Anfang der 1740er Jahre entstanden zu sein.

description: Johann Sebastian Bach lernte während seiner Schulzeit in Lüneburg (1700-1702) zweifellos Georg Böhm (1661-1733) kennen, der damals als Organist der Johanniskirche tätig war. Dennoch zeigt eine Analyse von Bachs frühen Orgel- und Klavierwerken, dass sie erst um 1708 wesentlich vom Kompositionsstil Böhms beeinflusst wurden. Viele spezifische Merkmale deuten auf die Verwendung von Böhms Werken als Modelle hin. Dies betrifft Struktur, Modulationen, Verzierungen, Behandlung von Choralmelodien und Einbeziehung von Tanzarten. (Übertragung des englischen Resümees am Ende des Bandes)

Data Management Plan

description: This deliverable presents the final version of the Data Management Plan, which is directly connected with the work performed under tasks T10.1 – “Project coordination and management” and T10.2 - “T10.2 – Scientific & Technical MGT”, in the context of WP10 – “Project Coordination and Quality Assurance”. It serves as the final plan for the collection, organisation, storing and sharing of the knowledge and data created within the project. The described data management plan is formulated based on several inputs, namely: a) the SnR Description of Action (DOA) document, b) the European Commission guidelines for data management of H2020 research projects and c) the input from the project consortium members.
 The document contains the appropriate methodologies, tools and repositories for data management and dissemination of all available information generated by the SnR project. Such information includes, but is not limited to, scientific publications issued by the project’s consortium members, Open-Source software components along with the generated source code, simulation datasets, anonymous user statistics, project deliverables, etc.
 Most of this information is openly accessed and is compliant to EC’s Horizon 2020 guidelines and regulations regarding Open Research Data. For this reason, a descriptive template has been formulated, based on the FAIR principles, which was followed by all datasets during their lifetime and was updated if there was need.
 Finally, it is important to underline that the current deliverable is the final version of a living document which was continuously adapted depending on the needs of the project research and development objectives and based on the direct input from members of the consortium and actual system users.

Jahrhunderts hatten viele der in diesem Bereich tätigen Musiker ihre Ausbildung bei den Bach-Schülern Johann Friedrich Doles und Gottfried August Homilius erhalten. Eine Besonderheit der Musikgeschichte stellen die Werke von Johann Christian Kuntze (1747-1821) dar. Kuntze war zwar als Landwirt und Stadtrat in seiner Heimat Grumbach tätig, komponierte aber auch in seiner Freizeit und produzierte sechs Fugen zum Thema B-a-c-h in Erinnerung an J. S. Bach.

First-principles study of PbTiO$_3$ under uniaxial strains and stresses

description: The behavior of PbTiO$_3$ under uniaxial strains and stresses is investigated from first-principles calculations within density functional theory. We show that irrespectively of the uniaxial mechanical constraint applied, the system keeps a purely ferroelectric ground-state, with the polarization aligned either along the constraint direction ($FE_z$ phase) or along one of the pseudo-cubic axis perpendicular to it ($FE_x$ phase). This contrasts with the cases of isotropic or biaxial mechanical constraints for which novel phases combining ferroelectic and antiferrodistortive motions have been previously reported. Under uniaxial strain, PbTiO$_3$ switched from a $FE_x$ ground state under compressive strain to $FE_z$ ground-state under tensile strain, beyond a critical strain $η_{zz}^c \approx +1$\%. Under uniaxial stress, PbTiO$_3$ exhibits either a $FE_x$ ground state under compression ($σ_{zz} < 0$) or a $FE_z$ ground state under tension ($σ_{zz} > 0$). Here, however, an abrupt jump of the structural parameters is also predicted under both compressive and tensile stresses at critical values $σ_{zz} \approx$ $+2$ GPa and $- 8$ GPa. This behavior appears similar to that predicted under negative isotropic pressure and might reveal practically useful to enhance the piezoelectric response in nanodevices.

description: Recently normalized Laplacian matrices of graphs are studied as density matrices in quantum mechanics. Separability and entanglement of density matrices are important properties as they determine the nonclassical behavior in quantum systems. In this note we look at the graphs whose normalized Laplacian matrices are separable or entangled. In particular, we show that the number of such graphs is related to the number of 0-1 matrices that are line sum symmetric and to the number of graphs with at least one vertex of degree 1.

description: 1973 stellte Peter Schleuning die Frage, ob C. P. E. Bachs 1753 veröffentlichte Fantasie für Klavier in c-Moll Wq 63/6 nach dem Tod von Johann Sebastian Bach als "Tombeau" gedacht gewesen wäre. Eine gründliche Analyse des Werkes bestätigt diesen Verdacht; die unmissverständlichen B-a-c-h-Motive, ihre kompositorische Behandlung sowie der Gesamtaufbau der Fantasie deuten darauf hin, dass das Werk nach dem Vorbild einer nach den Regeln der Rhetorik gestalteten Trauerrede gestaltet ist. Wesentlich ist, dass Bachs Sohn seine Komposition auch mit der Tonsprache der berühmten Chromatischen Fantasie BWV 903 seines Vaters verbindet.

A Two-dimensional Algebraic Quantum Liquid Produced by an Atomic Simulator of the Quantum Lifshitz Model

Year: 2014
Subjects: subject: Quantum Gases (cond-mat.quant-gas)

description: Bosons have a natural instinct to condense at zero temperature. It is a long-standing challenge to create a high-dimensional quantum liquid that does not exhibit long-range order at the ground state, as either extreme experimental parameters or sophisticated designs of microscopic Hamiltonian are required for suppressing the condensation. Here, we show that ultra cold atoms with synthetic spin-orbit coupling provide physicists a simple and practical scheme to produce a two-dimensional algebraic quantum liquid at the ground state. This quantum liquid arises at a critical Lifshitz point, where the single-particle ground state shrinks to a point from a circle in the momentum space, and many fundamental properties of two-dimensional bosons are changed in its proximity. Such an ideal simulator of the quantum Lifshitz model allows experimentalists to directly visualize and explore the deconfinement transition of topological excitations, an intriguing phenomenon that is difficult to access in other systems.

description: Le dediche riportate nelle pubblicazioni di musica rappresentano spesso un tassello fondamentale nella ricostruzione del contesto storico-sociale in cui un'edizione di musica a stampa è stata concepita. Le dediche presenti nelle edizioni di Carlo Gesualdo, a motivo dello status sociale del Principe, evidenziano dinamiche eccentriche rispetto al normale rapporto tra musicista dedicante e mecenate dedicatario tipica delle pubblicazioni di quel periodo. Analizzando le dediche contenute nelle edizioni del primo Seicento del V libro di madrigali di Carlo Gesualdo si getta un fascio di luce sul mecenatismo nelle città italiane del Cinque e Seicento, evidenziando l'intenso impatto che l'opera del principe di Venosa ebbe sui suoi contemporanei.
description: The dedications found in music publications often represent a key piece in the reconstruction of the socio-historical context in which a printed music edition was conceived. The dedications found in the editions of Carlo Gesualdo, because of the Prince's social status, highlight eccentric dynamics with respect to the normal relationship between dedicating musician and dedicatory patron typical of publications of that period. Analyzing the dedications contained in the early seventeenth-century editions of Carlo Gesualdo's fifth book of madrigals sheds a beam of light on patronage in Italian cities in the sixteenth and seventeenth centuries, highlighting the intense impact that the work of the Prince of Venosa had on his contemporaries.

description: This paper presents a new color image enhancement technique based on modified MultiScale Retinex(MSR) algorithm and visual quality of the enhanced images are evaluated using a new metric, namely, wavelet energy. The color image enhancement is achieved by down sampling the value component of HSV color space converted image into three scales (normal, medium and fine) following the contrast stretching operation. These down sampled value components are enhanced using the MSR algorithm. The value component is reconstructed by averaging each pixels of the lower scale image with that of the upper scale image subsequent to up sampling the lower scale image. This process replaces dark pixel by the average pixels of both the lower scale and upper scale, while retaining the bright pixels. The quality of the reconstructed images in the proposed method is found to be good and far better then the other researchers method. The performance of the proposed scheme is evaluated using new wavelet domain based assessment criterion, referred as wavelet energy. This scheme computes the energy of both original and enhanced image in wavelet domain. The number of edge details as well as wavelet energy is less in a poor quality image compared with naturally enhanced image. Experimental results presented confirms that the proposed wavelet energy based color image quality assessment technique efficiently characterizes both the local and global details of enhanced image.

description: This BRIDGES national report analyses the main narratives developed in traditional and social media around three different case studies in Italy: the Sea Watch 3 landing to Lampedusa (2019), which was the first challenge of the new ‘populist’ government’s ‘closed ports’ policy; the debate on Ius soli (2017), charged with identity issues in clashing political and cultural narratives; and the attempted supremacist massacre in Macerata (2018), occurred during the election campaign and characterised by a debate conveying implicit ideas about deserving and non-deserving victims. Following WP3 main objectives, the report addresses four interrelated questions: who accesses the public arena and shapes prevailing narratives; where these narratives emerge and how do they travel across different media and platforms; what the main features of successful narratives are; and in which contexts and circumstances (thus when) certain narratives obtain a competitive edge. Each event is analysed considering the news published during the peak period by three major newspapers and two prime-time news broadcasts, as well as using meta and textual data from Twitter. Interviews with relevant stakeholders involved in each event are also used to improve interpretation. The analysis of three case studies very different in nature shows the extreme polarisation of the political debate on immigration in Italy, the almost total exclusion of migrants’ voices from the public sphere, and the different – successful or unsuccessful – strategies employed by the two major political sides.

description: Melody Leung interviews her mother, Bonnie Lau, about her experiences of energy systems from her childhood in rural, mainland China during the Great Leap Forward to her move to Hong Kong. Lau recalls that in the village, everyone relied on a nearby river for water. On a nearby plain, villagers grew vegetables and rice. Lau reflects on the sharing of natural resources and on government flood management during seasons of heavy rain. She also discusses the distribution of labor among her family and among the entire village, along with the distribution of food and resources. Lau recalls burning straw for cooking and relying on manual labor for farming. She also describes moving to Hong Kong in her late teens. Lau discusses the slow introduction of electricity in the 1970s, replacing kerosene lamps. She also reflects on the different forms of energy used in urban and rural China and discusses what day-to-day life resembled for Chinese families. Lau concludes by discussing lifestyle changes in Chinese villages due to automation and describing the main forms of transportation during her childhood.

description: This letter and its two attached reports concern observations made in June of 2005 at Building 4193, Fort Sam Houston, Texas. Geo-Marine, Inc. (GMI), and its consultants, Mr. Joe Freeman (Historic Architect) and Jaster-Quintanilla (Structural Engineers), were asked to evaluate the structural and architectural conditions of the building, its integrity, and its potential for reuse in an administrative or similar function. This evaluation includes consideration of building code requirements, floor load requirements, accessibility, and the property’s historic status. Building 4193, built in 1941, is one of a collection of World War II-era warehouses located outside of the National Historic Landmark District and Conservation District at Fort Sam Houston. However, the building is recognized as eligible for inclusion in the National Register of Historic Places under National Register Criterion A (historical significance).

description: Glasses and other non-crystalline solids exhibit thermal and acoustic properties at low temperatures anomalously different from those found in crystalline solids, and with a remarkable degree of universality. Below a few K, these universal properties have been successfully interpreted using the Tunneling Model, which has enjoyed (almost) unanimous recognition for decades. Here we present low-temperature specific-heat measurements of ultrastable glasses of indomethacin that clearly show the disappearance of the ubiquitous linear contribution traditionally ascribed to the existence of tunneling two-level systems (TLS). When the ultrastable thin-film sample is thermally converted into a conventional glass, the material recovers a typical amount of TLS. This remarkable suppression of the TLS found in ultrastable glasses of indomethacin is argued to be due to their particular anisotropic and layered character, which strongly influences the dynamical network and may hinder isotropic interactions among low-energy defects, rather than to the thermodynamic stabilization itself. This explanation may lend support to the criticisms by Leggett and others to the standard Tunneling Model, although more experiments in different kinds of ultrastable glasses are needed to ascertain this hypothesis.
