description: The 22.2 GHz water masers are often associated with the 6.7 GHz methanol masers but owing to the different excitation conditions they likely probe independent spatial and kinematic regions around the powering young massive star. We compared the emission of these two maser species on milliarcsecond scales to determine in which structures the masers arise and to test a disc-outflow scenario where the methanol emission arises in a circumstellar disc while the water emission comes from an outflow. We obtained high-angular and spectral resolution 22.2 GHz water maser observations of the two sources G31.581+00.077 and G33.641-00.228 using the EVN. In both objects the water maser spots form complex and filamentary structures of sizes 18-160 AU. The emission towards the source G31.581+00.077 comes from two distinct regions of which one is related to the methanol maser source of ring-like shape. In both targets the main axis of methanol distribution is orthogonal to the water maser distribution. Most of water masers appear to trace shocks on a working surface between an outflow/jet and a dense envelope. Some spots are possibly related to the disc-wind interface which is as close as 100-150 AU to the regions of methanol emission.

description: A theoretical investigation of the possible existence of the chiral polaron formation in graphene is reported. We present an analytical method to calculate the ground-state of the electron-phonon system within the framework of the Lee-Low and Pines theory. On the basis of our model, the influence of electron-optical phonon interaction onto the graphene electronic spectrum is examined. In this paper, we only considered doubly degenerate optical phonon modes of E_2g symmetry near the zone center Gamma. We show analytically that the energy dispersions of both valance and conduction bands of the pristine graphene differ significantly than those obtained through the standard electron self energy calculations due to the electron-phonon interactions. Furthermore, we prove that the degenerate band structure of the graphene promote the chiral polaron formation.

description: A role of the superposition principle is discussed for the quantum-mechanical Carnot engine introduced by Bender, Brody, and Meister [J. Phys. A 33, 4427 (2000)]. It is shown that the efficiency of the engine can be enhanced by superposition of quantum states. A finite-time process is also discussed, and the condition of the maximum power output is presented. Interestingly, the efficiency at the maximum power is lower than that without superposition.

description: In this investigation we quantify the metallicities of low mass galaxies by constructing the most comprehensive census to date. We use galaxies from the SDSS and DEEP2 survey and estimate metallicities from their optical emission lines. We also use two smaller samples from the literature which have metallicities determined by the direct method using the temperature sensitive [OIII]4363 line. We examine the scatter in the local mass-metallicity (MZ) relation determined from ~20,000 star-forming galaxies in the SDSS and show that it is larger at lower stellar masses, consistent with the theoretical scatter in the MZ relation determined from hydrodynamical simulations. We determine a lower limit for the scatter in metallicities of galaxies down to stellar masses of ~10^7 M_solar that is only slightly smaller than the expected scatter inferred from the SDSS MZ relation and significantly larger than what is previously established in the literature. The average metallicity of star-forming galaxies increases with stellar mass. By examining the scatter in the SDSS MZ relation, we show that this is mostly due to the lowest metallicity galaxies. The population of low mass, metal-rich galaxies have properties which are consistent with previously identified galaxies that may be transitional objects between gas-rich dwarf irregulars and gas-poor dwarf spheroidals and ellipticals.

description: We have completed an optical spectroscopic survey of an unbiased, extinction-limited sample of candidate young stars covering 1.3 square degrees of the Rho Ophiuchi star forming region. While infrared, X-ray, and optical surveys of the cloud have identified many young stellar objects (YSOs), these surveys are biased towards particular stages of stellar evolution and are not optimal for studies of the disk frequency and initial mass function.We have obtained over 300 optical spectra to help identify 135 association members based on the presence of H-alpha in emission, lithium absorption, X-ray emission, a mid-infrared excess, a common proper motion, reflection nebulosity, and/or extinction considerations. Spectral types along with R and I band photometry were used to derive effective temperatures and bolometric luminosities for association members to compare with theoretical tracks and isochrones for pre-main-sequence stars. An average age of 3.1 Myr is derived for this population which is intermediate between that of objects embedded in the cloud core of Rho Ophiuchi and low mass stars in the Upper Scorpius subgroup. Consistent with this age we find a circumstellar disk frequency of 27% plus or minus 5%. We also constructed an initial mass function for an extinction-limited sample of 123 YSOs (A_v less than or equal to 8 mag), which is consistent with the field star initial mass function for YSOs with masses > 0.2 M_sun. There may be a deficit of brown dwarfs but this result relies on completeness corrections and requires confirmation.

It is shown, in the framework of the Bean critical-state model, that the radial temperature gradient appearing in tablets or annuli during a pulsed field magnetization can explain the negative magnetic relaxation in the superconductor.

Formation of galactic nuclei with multiple supermassive black holes at high redshifts

description: We examine the formation of groups of multiple supermassive black holes (SMBHs) in gas-poor galactic nuclei due to the high merger rate of galaxies at high redshifts. We calculate the relative likelihood of binary, triple, and quadruple SMBH systems, by considering the timescales for relevant processes and combining merger trees with N-body simulations for the dynamics of stars and SMBHs in galactic nuclei. Typical haloes today with mass $M_0\approx 10^{14}$ M$_\odot$ have an average mass $M_{z=6}=5\times 10^{11}$ M$_\odot$ at $z\sim 6$, while rare haloes with current mass $M_0\gtrsim 10^{15}$ M$_\odot$ have an average mass $M_{z=6}=5\times 10^{12}$ M$_\odot$ at that redshift. These cluster-size haloes are expected to host single galaxies at $z\sim 6$. We expect about 30% galaxies within haloes with present-day mass $M_0\approx 10^{14}$ M$_\odot$ to contain more than two SMBHs at redshifts $2\lesssim z\lesssim 6$. For larger present-day haloes, with $M_0\gtrsim 10^{15}$ M$_\odot$, this fraction is almost 60%. The existence of multiple SMBHs at high redshifts can potentially explain the mass deficiencies observed in the cores of massive elliptical galaxies, which are up to 5 times the mass of their central BHs. Multiple SMBHs would also lead to an enhanced rate of tidal disruption of stars, modified gravitational wave signals compared to isolated BH binaries, and slingshot ejection of SMBHs from galaxies at high speeds in excess of 2000 km s$^{-1}$.

Bewertung des unmittelbaren Wohnumfelds durch Affective Content Analysis und Computer Vision

description: Die unmittelbare Umgebung von Wohngebäuden hat einen erheblichen Einfluss auf das Wohlbefinden der Bewohner und damit auf den Wert von Immobilien. Inzwischen gibt es eine große Menge an verfügbaren multimodalen, halbstrukturierten und unstrukturierten nützlichen Informationen, die in Lagebewertungsmodelle integriert werden können. Die Integration alternativer Daten­extraktionsansätze, z. B. für visuelle oder textuelle Daten, sowie die Fähigkeit, größere Datensätze mit Hilfe von maschinellem Lernen zu verarbeiten, können die Schwierigkeiten bei der Modellierung erheblich verringern und gleichzeitig Daten aus neuen Quellen und Modalitäten einbeziehen. Wir stellen daher die Hypothese auf, dass die Informationsqualität bei den Daten für eine automatisierte Bewertung weniger Verzerrung aufweist, wenn die Datenannotation von mehreren unabhängigen Personen vorgenommen wird. Darüber hinaus sollten wiederholte Schätzungen einer Person auch die Gesamtfehlervarianz verringern und infolgedessen den Erwartungsbereich der Schätzungen verkleinern, was zu robusteren Ergebnissen führen sollte. Die Grundlage unseres Ansatzes zur Lagebewertung ist eine von Menschen vorgenommene Bewertung von Bildern der unmittelbaren Wohnumgebung unter Verwendung von Elo-Rating, Alternative Forced Choice und einer Back-End-Berechnung von Qualitätspunkten. Der i. d. R. große Aufwand, der für manuelle Ground-Truth-Annotationen erforderlich ist, rechtfertigt Erzeugung synthetischer Daten im Hinblick auf die benötigte Datenmenge für Machine Learning Modelle. Daher verwenden wir ein neuronales Netz für die Regressionsaufgabe, um neue synthetische Daten unter Einbeziehung menschlicher Schätzungen zu generieren und testen den Effekt synthetischer Daten in einem hedonischen Modell. Die experimentellen Ergebnisse zeigen, dass die Qualität der unmittelbaren Umgebung anhand der vorhergesagten Scores zuverlässig ermittelt werden kann. Der vorgestellte Ansatz ist nicht rechenintensiv, kann subjektive Bewertungen von visuellen Merkmalen durch mehrere Personen effizient fusionieren und leicht an maschinelle Lernansätze im weiteren Sinne adaptiert oder auf andere Anwendungsfälle übertragen werden.

description: White light interferometry (WLI) can be used to obtain surface morphology information on dimensional scale of millimeters with lateral resolution as good as ~1 μm and depth resolution down to 1 nm. By performing true three-dimensional imaging of sample surfaces, the WLI technique enables accurate quantitative characterization of the geometry of surface features and compares favorably to scanning electron and atomic force microscopies by avoiding some of their drawbacks. In this paper, results of using the WLI imaging technique to characterize the products of ion sputtering experiments are reported. With a few figures, several example applications of the WLI method are illustrated when used for (i) sputtering yield measurements and time-to-depth conversion, (ii) optimizing ion beam current density profiles, the shapes of sputtered craters, and multiple ion beam superposition and (iii) quantitative characterization of surfaces processed with ions. In particular, for sputter depth profiling experiments of 25Mg, 44Ca and 53Cr ion implants in Si (implantation energy of 1 keV per nucleon), the depth calibration of the measured depth profile curves determined by the WLI method appeared to be self-consistent with TRIM simulations for such projectile-matrix systems. In addition, high depth resolution of the WLI method is demonstrated for a case of a Genesis solar wind Si collector surface processed by gas cluster ion beam: a 12.5 nm layer was removed from the processed surface, while the transition length between the processed and untreated areas was 150 μm.

description: In a long-held preconception, photons play a central role in present-day quantum technologies. But what are sources producing photons one by one good for precisely? Well, in opposition to what many suggest, we show that single-photon sources are not helpful for point to point quantum key distribution because faint laser pulses do the job comfortably. However, there is no doubt about the usefulness of sources producing single photons for future quantum technologies. In particular, we show how single-photon sources could become the seed of a revolution in the framework of quantum communication, making the security of quantum key distribution device independent or extending quantum communication over many hundreds of kilometers. Hopefully, these promising applications will provide a guideline for researchers to develop more and more efficient sources, producing narrowband, pure and indistinguishable photons at appropriate wavelengths.

We show that the six-point amplitude in the maximally supersymmetric, N=8, theory can be arranged so that the kinematic factors satisfy the fundamental identity of three-algebras. We further show that the four- and six-point N=8 amplitudes can be "squared" into the amplitudes of N=16 three-dimensional supergravity, thus providing evidence for a hidden three-algebra structure in the dynamics of the supergravity.

description: The nearby dwarf starburst galaxy NGC 5253 hosts a deeply embedded radio-infrared supernebula excited by thousands of O stars. We have observed this source in the 10.5μm line of S+3 at 3.8 kms-1 spectral and 1.4" spatial resolution, using the high resolution spectrometer TEXES on the IRTF. The line profile cannot be fit well by a single Gaussian. The best simple fit describes the gas with two Gaussians, one near the galactic velocity with FWHM 33.6 km s-1 and another of similiar strength and FWHM 94 km s-1 centered \sim20 km s-1 to the blue. This suggests a model for the supernebula in which gas flows towards us out of the molecular cloud, as in a "blister" or "champagne flow" or in the HII regions modelled by Zhu (2006).

description: The diffusion of two dimensional adatom islands (up to 100 atoms) on Cu(111) has been studied, using the self-learning Kinetic Monte Carlo (SLKMC) method [1]. A variety of multiple- and single-atom processes are revealed in the simulations, and the size dependence of the diffusion coefficients and effective diffusion barriers are calculated for each. From the tabulated frequencies of events found in the simulation, we show a crossover from diffusion due to the collective motion of the island to a regime in which the island diffuses through periphery-dominated mass transport. This crossover occurs for island sizes between 13 and 19 atoms. For islands containing 19 to 100 atoms the scaling exponent is 1.5, which is in good agreement with previous work. The diffusion of islands containing 2 to 13 atoms can be explained primarily on the basis of a linear increase of the barrier for the collective motion with the size of the island.

description: Die Archäologie der frühesten Menschheitsgeschichte befindet sich in einer taxonomischen Krise, die sich vor allem aus den Ansprüchen von Open Science und der Verfügbarkeit moderner quantitativer Analyseverfahren ergibt. Wir legen die Motivation sowie die vorläufigen Ergebnisse des ersten vom Europäischen Wissenschaftsrat geförderten CLIOARCH Workshops zu diesem Thema dar und erörtern die Dringlichkeit einer grundlegenden Revision archäologischer Kultureinheiten in der frühen Menschheitsgeschichte. Der Bericht endet mit einem kurzen Plädoyer für einen neuen Dialog zwischen Archäologie und Wissenschaftsphilosophie.

description: Whenever observations are compared to theories, an estimate of the uncertainties associated with the observations is vital if the comparison is to be meaningful. However, many determinations of temperatures, densities and abundances in photoionized nebulae do not quote the associated uncertainty. Those that do typically propagate the uncertainties using analytical techniques which rely on assumptions that generally do not hold. Motivated by this issue, we have developed NEAT (Nebular Empirical Analysis Tool), a new code for calculating chemical abundances in photoionized nebulae. The code carries out an analysis of lists of emission lines using long-established techniques to estimate the amount of interstellar extinction, calculate representative temperatures and densities, compute ionic abundances from both collisionally excited lines and recombination lines, and finally to estimate total elemental abundances using an ionization correction scheme. NEAT uses a Monte Carlo technique to robustly propagate uncertainties from line flux measurements through to the derived abundances. We show that for typical observational data, this approach is superior to analytic estimates of uncertainties. NEAT also accounts for the effect of upward biasing on measurements of lines with low signal to noise, allowing us to accurately quantify the effect of this bias on abundance determinations. We find not only that the effect can result in significant over-estimates of heavy element abundances derived from weak lines, but that taking it into account reduces the uncertainty of these abundance determinations. Finally, we investigate the effect of possible uncertainties in R, the ratio of selective to total extinction, on abundance determinations. We find that the uncertainty due to this parameter is negligible compared to the statistical uncertainties due to typical line flux measurement uncertainties.

description: We describe the effect of thermal motion and buffer-gas collisions on a four-level closed N system interacting with strong pump(s) and a weak probe. This is the simplest system that experiences electromagnetically induced absorption (EIA) due to transfer of coherence via spontaneous emission from the excited to ground state. We investigate the influence of Doppler broadening, velocity-changing collisions (VCC), and phase-changing collisions (PCC) with a buffer gas on the EIA spectrum of optically active atoms. In addition to exact expressions, we present an approximate solution for the probe absorption spectrum, which provides physical insight into the behavior of the EIA peak due to VCC, PCC, and wave-vector difference between the pump and probe beams. VCC are shown to produce a wide pedestal at the base of the EIA peak, which is scarcely affected by the pump-probe angular deviation, whereas the sharp central EIA peak becomes weaker and broader due to the residual Doppler-Dicke effect. Using diffusion-like equations for the atomic coherences and populations, we construct a spatial-frequency filter for a spatially structured probe beam and show that Ramsey narrowing of the EIA peak is obtained for beams of finite width.

description: Topological defects have been playgrounds for many emergent phenomena in complex matter such as superfluids, liquid crystals, and early universe. Recently, vortex-like topological defects with six interlocked structural antiphase and ferroelectric domains merging into a vortex core were revealed in multiferroic hexagonal manganites. Numerous vortices are found to form an intriguing self-organized network. Thus, it is imperative to find out the magnetic nature of these vortices. Using cryogenic magnetic force microscopy, we discovered unprecedented alternating net moments at domain walls around vortices that can correlate over the entire vortex network in hexagonal ErMnO3 The collective nature of domain wall magnetism originates from the uncompensated Er3+ moments and the correlated organization of the vortex network. Furthermore, our proposed model indicates a fascinating phenomenon of field-controllable spin chirality. Our results demonstrate a new route to achieving magnetoelectric coupling at domain walls in single-phase multiferroics, which may be harnessed for nanoscale multifunctional devices.

MARCMUS, a repository of music paper-types and handwriting: proposals and challenges in the establishment of a method
Creators: name: Chaves, Zuelma
name: Sousa, Pedro
Publisher: name: Zenodo
Year: 2023

description: MARCMUS is a project that focuses on the virtually unexplored music manuscripts from the collection of the 15th Count of Redondo, now housed at Biblioteca Nacional de Portugal (BNP, National Library of Portugal).
The characteristics of the collection of the Count of Redondo make it ideal for a case study of source criticism in Portuguese music.
The project aims to systematically record and digitally preserve the watermarks and paper-types (the conjunction of the watermark and the number and size of staves drawn by rastra) of the collection's music manuscripts. It will also record the literary and music handwritings of the copyists and composers involved (preliminary research has shown that the collection possesses a significant number of autographs). The project site will allow free access to the resulting interrelational databases (watermarks, rastrologies, paper-types and handwritings).
In an initial phase of the MARCMUS project, three major stages were established, namely, the identification and selection of the elements to be digitised, the digitisation itself and the respective processing of the images, and, finally, the availability of results.
In this paper, read at the final MARCMUS colloquium, the methodological proposal for the treatment of the data obtained was presented, which, taking into account the current state of the art, incorporates the results of a discussion between specialists from fields as diverse as musicology, paper studies, archival science and librarianship, photography, IT and linguistics.
title: Efficacy of the Eastport Marine Protected Area for American lobster, Homarus americanus

description: Given global targets of protecting 10% of marine habitats by 2020, managers increasingly looked to Marine Protected Areas (MPAs) as a conservation tool. The Eastport MPA, designated in 2005, was established to protect a portion of the local American lobster (Homarus americanus) population. To determine MPA impacts on local lobster growth and reproduction, I analyzed 15 years of capture-mark-recapture data and egg samples from Eastport. Despite no significant trend in fecundity or size along a distance gradient from the MPA boundary, I detected increased egg production over time in the MPA. Female growth inside and outside remained steady over the tagging period in contrast to more variable male growth. Comparison of Eastport population fecundity and growth to other populations indicated higher fecundity at commercial size and slower rate of growth. These analyses provide inconclusive evidence regarding attainment of the original MPA conservation objectives, however, community-driven conservation could provide ecological benefits such as more careful handling of lobster that indirectly support these broader Eastport MPA objectives.

description: Der ökologische Landbau gilt als Leitbild für eine ressourcenschonende, biodiversitätsfördernde und umweltverträgliche Landbewirtschaftungsform. Wo genau sich die ökologisch bewirtschafteten Flächen befinden, geht aus den bisher veröffentlichten amtlichen statistischen Daten nicht hervor. Für eine Lokalisierung der ökologisch bewirtschafteten Flächen bieten sich Daten des Integrierten Verwaltungs- und Kontrollsystem (InVeKoS) an. InVeKoS dient als Kontrollinstrument für die Agrarausgaben der EU. Im Rahmen der Beantragung von EU-Agrarförderungen wird jährlich die Bewirtschaftung der Agrarflächen parzellenspezifisch von den Landbewirtschaftenden gemeldet. Neben Angaben zur Kulturart, können auch Angaben zur ökologischen Bewirtschaftung von Ackerschlägen aus diesen Daten gewonnen werden. So ermöglichen die Daten eine lagebezogene Auswertung der Ökoflächen, beispielsweise zum Anteil des Ökolandbaus in Schutzgebieten. Im Rahmen des Projektes „Diversity of Insects in Nature protected Areas“ (DINA) erfolgte eine Abfrage der ökologisch bewirtschafteten Ackerschläge aus InVeKoS bei den zuständigen Stellen aller Bundesländer. Erkenntnisse zur Lage der Ökolandbauflächen, den dort angebauten Kulturen und der Entwicklung des Flächenanteils über die letzten 3-5 Jahre konnten aus diesen Daten gewonnen werden.

description: In graphene, we report the first theoretical demonstration of how the intrinsic spin orbit interaction can be deduced from the theory and how it can be controlled by tuning a uniform magnetic field, and/or by changing the strength of a long range Coulomb like impurity (adatom), as well as gap parameter. In the impurity context, we find that intrinsic spin-orbit interaction energy may be enhanced by increasing the strength of magnetic field and/or by decreasing the band gap mass term. Additionally, it may be strongly enhanced by increasing the impurity strength. Furthermore, from the proposal of Kane and Mele [Phys. Rev. Lett. 95, 226801 (2005)], it was discussed that the pristine graphene has a quantized spin Hall effect regime where the Rashba type spin orbit interaction term is smaller than that of intrinsic one. Our analysis suggest the nonexistence of such a regime in the ground state of flat graphene.
