description: Mergers of binary neutron stars (NSs) usually result in the formation of a hypermassive neutron star (HMNS). Whether- and when this remnant collapses to a black hole (BH) depends primarily on the equation of state and on angular momentum transport processes, both of which are uncertain. Here we show that the lifetime of the merger remnant may be directly imprinted in the radioactively powered kilonova emission following the merger. We employ axisymmetric, time-dependent hydrodynamic simulations of remnant accretion disks orbiting a HMNS of variable lifetime, and characterize the effect of this delay to BH formation on the disk wind ejecta. When BH formation is relatively prompt (~ 100 ms), outflows from the disk are sufficiently neutron rich to form heavy r-process elements, resulting in ~ week-long emission with a spectral peak in the near-infrared (NIR), similar to that produced by the dynamical ejecta. In contrast, delayed BH formation allows neutrinos from the HMNS to raise the electron fraction in the polar direction to values such that potentially Lanthanide-free outflows are generated. The lower opacity would produce a brighter, bluer, and shorter-lived ~ day-long emission (a `blue bump') prior to the late NIR peak from the dynamical ejecta and equatorial wind. This new diagnostic of BH formation should be useful for events with a signal to noise lower than that required for direct detection of gravitational waveform signatures.

description: Rates of self-harm among children and adolescents have risen significantly over thepast decade and clinical guidelines place children’s nurses at the heart of their care. This article reports on the evaluation of ‘Our Care Through Our Eyes’, an online self-harm learning programme for children’s nurses. A self-selected, convenience sample of registered children’s nurses (n = 42) completed scales pre- and postlearning programme that captured their attitudes, beliefs, empathy, anxiety, and confidence. Mean change scores were assessed, and qualitative comments captured postintervention were thematically summarized. There were small improvements in participants’ attitudes, empathy and confidence were reported. Anxiety scores increased in a small number of items. Qualitative comments confirmed the value of the online learning programme for improving children’s nurses’ knowledge and understanding of self-harm among CYP. Our findings demonstrate that children’s nurses agree on the importance of mental health training in self harm, and this could be a catalyst for renewal of both pre- and postregistration education including support structures within the National Health Service. This study is the first to explore the feasibility of evaluating ‘Our Care Through Our Eyes’ delivered using e-leaning and could be used to inform further investigations

description: We propose a timed and soft extension of Concurrent Constraint Programming. The time extension is based on the hypothesis of bounded asynchrony: the computation takes a bounded period of time and is measured by a discrete global clock. Action prefixing is then considered as the syntactic marker which distinguishes a time instant from the next one. Supported by soft constraints instead of crisp ones, tell and ask agents are now equipped with a preference (or consistency) threshold which is used to determine their success or suspension. In the paper we provide a language to describe the agents behavior, together with its operational and denotational semantics, for which we also prove the compositionality and correctness properties. After presenting a semantics using maximal parallelism of actions, we also describe a version for their interleaving on a single processor (with maximal parallelism for time elapsing). Coordinating agents that need to take decisions both on preference values and time events may benefit from this language. To appear in Theory and Practice of Logic Programming (TPLP).

description: We consider weakly magnetized non-rotating black holes. In the presence of a regular magnetic field the motion of charged particles in the vicinity of a black hole is modified. As a result, the position of the innermost stable circular orbit (ISCO) becomes closer to the horizon. When the Lorentz force is repulsive (directed from the black hole) the ISCO radius can reach the gravitational radius. In the process of accretion charged particles (ions) of the accreting matter can be accumulated near their ISCO, while neutral particles fall down to the black hole after they reach $6M$ radius. The sharp spectral line Fe K$α$, emitted by iron ions at such orbits, is broadened when the emission is registered by a distant observer. In this paper we study this broadening effect and discuss how one can extract information concerning the strength of the magnetic field from the observed spectrum.

Near Mass Degeneracy in the Scalar Meson Sector: Implications for $B^*_{(s)0}$ and $B'_{(s)1}$ Mesons

description: The empirical observation of near degeneracy of scalar mesons above 1 GeV, namely, the mass of the strange-flavor scalar meson is similar to that of the non-strange one, is at variance with the naive expectation of the quark model. Qualitatively, the approximate mass degeneracy can be understood as a consequence of self-energy effects due to strong coupled channels which will push down the mass of the heavy scalar meson in the strange sector more than that in the non-strange partner. However, it works in the conventional model without heavy quark expansion, but not in the approach of heavy meson chiral perturbation theory as mass degeneracy and the physical masses of $D_{s0}^*$ and $D_0^*$ cannot be accounted for simultaneously. In the heavy quark limit, near mass degeneracy observed in the scalar charm sector will imply the same phenomenon in the $B$ system. We have the prediction $M_{B_0^*}\approx M_{B_{s0}^*}\approx 5715\,{\rm MeV}+δΔ_S$ based on heavy quark symmetry and the leading-order QCD correction, where $δΔ_S$ arises from $1/m_Q$ corrections. A crude estimate indicates that $δΔ_S$ is of order $-35$ MeV or less. We stress that the closeness of $B_{s0}^*$ and $B_0^*$ masses implied by heavy quark symmetry is not spoiled by $1/m_Q$ or QCD corrections. The mass-shift effect on $K_0^*(1430)$ is discussed.

description: Glaciers play a vital role in regulating the earth's climate and have societal as well as scientific significance. Acting as cultural heritage, ecosystem components, water storage and contributors to sea level rise, they have both direct and indirect impact on humanity. Vanishing glaciers are also some of the most readily available illustrations of climate change and emphasize the reality and urgency of climate change and its impact. There are approximately 216,000 glaciers globally, which are monitored and catalogued, providing large data sets for research in glaciology, hydrology, and climatology. Their mass changes provide valuable information about the state of the global climate and raise concerns about the potential impacts of climate change on freshwater resources and ecosystems. With their capacity for water storage, glacier mass change can affect and cause hydroclimatic events, including droughts and floods, and well as water availability: an essential aspect of the overall water cycle. In order for communities to increase their resilience to these changes, there is a need for reliable predictions of the magnitude and timing of glacier mass loss on seasonal to decadal time scales, referred to as near-term. The aim of this study is to improve our understanding of glacier modelling on this time scale and analyze the utility of seasonal to decadal scale forcing in a global glacier model. Through the application of a scenario-neutral approach, the concept of glacier sensitivity is explored, while providing a framework in which to analyze and better understand glacier response to changes in temperature and precipitation on various scales. Next, the potential of seasonal forecasting with Open Global Glacier Model (OGGM) is assessed. The glacier model is forced with a multi-model ensemble of seasonal forecasts. The results are interpreted in terms of predictive skill: whether the upcoming season would be above or below a certain mass balance threshold. This type of coarse information could provide valuable early warning information for water resource management, but is not attained with the current approach. The final component of this study is the application of decadal (retrospective) forecasts in mass balance and runoff modelling with OGGM. The results with this method show similar or better skill when compared to a simple persistence approach and to the current state of the art in predicting glacier evolution for the 21st century, climate projections. Forcing OGGM with these type of initialized forecasts could complement centennial scale glacier and climate modelling, providing information on a time scale that is particularly relevant for water resource management.

description: Purpose: The perception of a clinical condition or disorder can vary across patients from different cultural–linguistic backgrounds. There is insufficient evidence to inspect this potential impact on the perception of vocal fatigue (VF) as a common condition perceived by patients with voice disorders. In order to more comprehensively explore this phenomenon, a systematic review was carried out to investigate the differences in perceived VF in a variety of cultural–linguistic contexts, based on a standard self-assessment instrument—the Vocal Fatigue Index (VFI), as translated in different languages.Method: A thorough search was done in MEDLINE, CENTRAL, Web of Science, and Google Scholar by March 2024. Cross-sectional studies investigating the accuracy of the VFI to detect perceived VF in all available languages were considered. The VFI has three distinct parts or factors assessing: (a) tiredness of voice, (b) physical discomfort associated with voicing, and (c) improvement of symptoms with rest. The cutoff points and sensitivity and specificity of each factor were submitted to meta-analysis, and the summary receiver operating characteristic curves were used to determine pooled sensitivity and specificity of each factor of the VFI.Results: Eight papers that examined the diagnostic accuracy of the VFI in English, Malayalam, Turkish, German, Mandarin Chinese, Polish, Cantonese, and Finnish languages were identified as being eligible for this meta-analysis. The pooled sensitivity and specificity along with their confidence intervals (CIs) were as follows: 0.91 CI [0.80, 0.96] and 0.88 CI [0.78, 0.94] for Factor 1, 0.83 CI [0.69, 0.91] and 0.84 CI [0.76, 0.89] for Factor 2, and 0.75 CI [0.67, 0.82] and 0.77 CI [0.59, 0.89] for Factor 3.Conclusions: The present research demonstrates medium to high but heterogeneous accuracy of the VFI for detecting perceived VF across cultural–linguistic contexts. Given the promising results, future studies should focus on (a) further investigating the underlying factors for the observed heterogeneity in diagnostic accuracy and (b) adapting and validating the VFI in more languages toward establishing its validity as a cross-linguistic diagnostic tool for the perception of VF.Supplemental Material S1.

description: Historically, appearance of the quantum theory led to a prevailing view that Nature is indeterministic. The arguments for the indeterminism and proposals for indeterministic and deterministic approaches are reviewed. These include collapse theories, Bohmian Mechanics and the many-worlds interpretation. It is argued that ontic interpretations of the quantum wave function provide simpler and clearer physical explanation and that the many-worlds interpretation is the most attractive since it provides a deterministic and local theory for our physical Universe explaining the illusion of randomness and nonlocality in the world we experience.

description: The creation of a quantum network requires the distribution of coherent information across macroscopic distances. We demonstrate the entanglement of two superconducting qubits, separated by more than a meter of coaxial cable, by designing a joint measurement that probabilistically projects onto an entangled state. By using a continuous measurement scheme, we are further able to observe single quantum trajectories of the joint two-qubit state, confirming the validity of the quantum Bayesian formalism for a cascaded system. Our results allow us to resolve the dynamics of continuous projection onto the entangled manifold, in quantitative agreement with theory.

description: To harness the full potential of human pluripotent stem cells (hPSCs) we combined instrumented stirred tank bioreactor (STBR) technology with the power of in silico process modeling to overcome substantial, hPSC-specific hurdles toward their mass production. Perfused suspension culture (3D) of matrix-free hPSC aggregates in STBRs was applied to identify and control process-limiting parameters including pH, dissolved oxygen, glucose and lactate levels, and the obviation of osmolality peaks provoked by high density culture. Media supplements promoted single cell-based process inoculation and hydrodynamic aggregate size control. Wet lab-derived process characteristics enabled predictive in silico modeling as a new rational for hPSC cultivation. Consequently, hPSC line-independent maintenance of exponential cell proliferation was achieved. The strategy yielded 70-fold cell expansion in 7 days achieving an unmatched density of 35 × 106 cells/mL equivalent to 5.25 billion hPSC in 150 mL scale while pluripotency, differentiation potential, and karyotype stability was maintained. In parallel, media requirements were reduced by 75% demonstrating the outstanding increase in efficiency. Minimal input to our in silico model accurately predicts all main process parameters; combined with calculation-controlled hPSC aggregation kinetics, linear process upscaling is also enabled and demonstrated for up to 500 mL scale in an independent bioreactor system. Thus, by merging applied stem cell research with recent knowhow from industrial cell fermentation, a new level of hPSC bioprocessing is revealed fueling their automated production for industrial and therapeutic applications.

It is found to be especially useful for restricted geometries such as microstructures for which boundary conditions are well known to play an important role in ferroelectric properties. We have explored a new switching mechanism, which consists of an inhomogeneous rotational motion of the polarization and leads to an extended vortex state. The vortex appearance exhibits characteristic properties of a first-order field-induced phase transition: three critical electric fields and the possibility of hysteresis behavior.

description: In recent years, stem cell-derived organoids have become a cell culture standard that is widely used for studying various scientific issues that were previously investigated through animal experiments and using common tumor cell lines. After their initial hype, concerns regarding their standardization have been raised. Here, we aim to provide some insights into our experience in standardizing murine colonic epithelial organoids, which we use as a replacement method for research on inflammatory bowel disease. Considering good scientific practice, we examined various factors that might challenge the design and outcome of experiments using these organoids. First, to analyze the impact of antibiotics/antimycotics, we performed kinetic experiments using ZellShield® and measured the gene expression levels of the tight junction markers Ocln, Zo-1, and Cldn4, the proliferation marker Ki67, and the proinflammatory cytokine Tnfα. Because we found no differences between cultivations with and without ZellShield®, we then performed infection experiments using the probiotic Escherichia coli Nissle 1917 as an already established model setup to analyze the impact of technical, interexperimental, and biologic replicates. We demonstrate that interexperimental differences pose the greatest challenge for reproducibility and explain our strategies for addressing these differences. Additionally, we conducted infection experiments using freshly isolated and cryopreserved/thawed organoids and found that cryopreservation influenced the experimental outcome during early passages. Formerly cryopreserved colonoids exhibited a premature appearance and a higher proinflammatory response to bacterial stimulation. Therefore, we recommend analyzing the growth characteristics and reliability of cryopreserved organoids before to their use in experiments together with conducting several independent experiments under standardized conditions. Taken together, our findings demonstrate that organoid culture, if standardized, constitutes a good tool for reducing the need for animal experiments and might further improve our understanding of, for example, the role of epithelial cells in inflammatory bowel disease development.

description: Metallicity is a fundamental parameter that contributes to the physical characteristics of a star. However, the low temperatures and complex molecules present in M dwarf atmospheres make it difficult to measure their metallicities using techniques that have been commonly used for Sun-like stars. Although there has been significant progress in developing empirical methods to measure M dwarf metallicities over the last few years, these techniques have been developed primarily for early- to mid-M dwarfs. We present a method to measure the metallicity of mid- to late-M dwarfs from moderate resolution (R~2000) K-band (2.2 microns) spectra. We calibrate our formula using 44 wide binaries containing an F, G, K, or early M primary of known metallicity and a mid- to late-M dwarf companion. We show that similar features and techniques used for early M dwarfs are still effective for late-M dwarfs. Our revised calibration is accurate to 0.07 dex for M4.5-M9.5 dwarfs with -0.58

description: The Standard Model of particle physics fails to explain the important pieces in the standard cosmology, such as inflation, baryogenesis, and dark matter of the Universe. We consider the possibility that the sector to generate small neutrino masses is responsible for all of them; the inflation is driven by the Higgs field to break $B-L$ gauge symmetry which provides the Majorana masses to the right-handed neutrinos, and the reheating process by the decay of the $B-L$ Higgs boson supplies the second lightest right-handed neutrinos whose CP violating decays produce $B-L$ asymmetry, a la, leptogenesis. The lightest right-handed neutrinos are also produced by the reheating process, and remain today as the dark matter of the Universe. In the minimal model of the inflaton potential, one can set the parameter of the potential by the data from CMB observations including the BICEP2 and the Planck experiments. In such a scenario, the mass of the dark matter particle is predicted to be of the order of PeV. We find that the decay of the PeV right-handed neutrinos can explain the high-energy neutrino flux observed at the IceCube experiments if the lifetime is of the order of $10^{28}$ s.

description: Summer temperatures are often above freezing along the Antarctic coastline, which makes ice shelves and coastal snowpacks vulnerable to warming events (understood as periods of consecutive days with warmer than usual conditions). Here, we project changes in the frequency, duration and amplitude of summertime warming events expected until end of century according to two emission scenarios. By using both global and regional climate models, we found that these events are expected to be more frequent and last longer, continent-wide. By end of century, the number of warming events is projected to double in most of West Antarctica and to triple in the vast interior of East Antarctica, even under a moderate-emission scenario. We also found that the expected rise of warming events in coastal areas surrounding the continent will likely lead to enhanced surface melt, which may pose a risk for the future stability of several Antarctic ice shelves.

description: We present a new efficient numerical approach for representing anisotropic physical quantities and/or matrix elements defined on the Fermi surface of metallic materials. The method introduces a set of numerically calculated generalized orthonormal functions which are the solutions of the Helmholtz equation defined on the Fermi surface. Noteworthy, many properties of our proposed basis set are also shared by the Fermi Surface Harmonics (FSH) introduced by Philip B. Allen [Physical Review B 13, 1416 (1976)], proposed to be constructed as polynomials of the cartesian components of the electronic velocity. The main motivation of both approaches is identical, to handle anisotropic problems efficiently. However, in our approach the basis set is defined as the eigenfunctions of a differential operator and several desirable properties are introduced by construction. The method demonstrates very robust in handling problems with any crystal structure or topology of the Fermi surface, and the periodicity of the reciprocal space is treated as a boundary condition for our Helmholtz equation. We illustrate the method by analysing the free-electron-like Lithium (Li), Sodium (Na), Copper (Cu), Lead(Pb), Tungsten (W) and Magnesium diboride (MgB2).

description: Tool grinding is an essential process for the production of cemented carbide tools. In that context, the investigation of specific effects like the resulting surface profile and the fluid dynamic processes is of great interest, but requires microscopic modeling of the grinding wheel including its individual grains and bonding material. This paper introduces an approach for a parametric grinding wheel model, which provides a topography on microscopic scale depending on the grinding wheel specification and dressing conditions for subsequent use in material removal simulations. Scalable abrasive grains and variable distributions embedded in a shiftable bond layer are applied. Optical laser scans are used to derive surface parameters for an adaption and evaluation of the model. The prediction quality in terms of surface roughness is evaluated in surface grinding reference experiments.

description: We present large scale observations of C18O(1-0) towards four massive star forming regions for MON R2, S156, DR17/L906 and M17/M18. The transitions of H2CO(110-111), C18O(1-0) and 6 cm continuum were compared towards the four regions. Analysis of observation and Non--LTE model results shows that the brightness temperature of the formaldehyde absorption line is strongest in background continuum temperature range of about 3 - 8 K. The excitation of the H2CO absorption line is affected by strong background continuum emission. From the comparison of H2CO and C18O maps, we found that the extent of H2CO absorption is broader than that of C18O emission in the four regions. Except for the DR17 region, the H2CO absorption maximum is located at the same position with the C18O peak. The good correlation between intensities and widths of H2CO absorption and C18O emission lines indicate that the H2CO absorption line can trace dense and warm regions of the molecular cloud. Finding that N(H2CO) was well correlated with N(C18O) in the four regions and that the average column density ratio is ~ 0.03.

description: Land use is an important piece of information with many applications. Commonly, land use is stored in geospatial databases in the form of polygons with corresponding land use labels and attributes according to an object catalogue. The object catalogues often have a hierarchical structure, with the level of detail of the semantic information depending on the hierarchy level. In this paper, we extend our prior work for the CNN (Convolutional Neural Network)-based prediction of land use for database objects at multiple semantic levels corresponding to different levels of a hierarchical class catalogue. The main goal is the improvement of the classification accuracy for small database objects, which we observed to be one of the largest problems of the existing method. In order to classify large objects using a CNN of a fixed input size, they are split into tiles that are classified independently before fusing the results to a joint prediction for the object. In this procedure, small objects will only be represented by a single patch, which might even be dominated by the background. To overcome this problem, a multi-scale approach for the classification of small objects is proposed in this paper. Using this approach, such objects are represented by multiple patches at different scales that are presented to the CNN for classification, and the classification results are combined. The new strategy is applied in combination with the earlier tiling-based approach. This method based on an ensemble of the two approaches is tested in two sites located in Germany and improves the classification performance up to +1.8% in overall accuracy and +3.2% in terms of mean F1 score.

description: Let $E$ be a non-Archimedian local field of characteristic zero and residue characteristic $p$. Let ${\bf G}$ be a connected reductive group defined over $E$ and $π$ an irreducible admissible representation of $G={\bf G}(E)$. A result of C. Mœglin and J.-L. Waldspurger (for $p \neq 2$) and S. Varma (for $p=2$) states that the leading coefficient in the character expansion of $π$ at the identity element of ${\bf G}(E)$ gives the dimension of a certain space of degenerate Whittaker forms. In this paper we generalize this result of Mœglin-Waldspurger to the setting of covering groups $\tilde{G}$ of $G$.

description: A self-consistent exposition of the theory of tree-level superamplitudes of the 4d N=4 and 6d N=(1,1) maximally supersymmetric Yang-Mills theories is provided. In 4d we work in non-chiral superspace and construct the superconformal and dual superconformal symmetry generators of the N=4 SYM theory using the non-chiral BCFW recursion to prove the latter. In 6d we provide a complete derivation of the standard and hidden symmetries of the tree-level superamplitudes of N=(1,1) SYM theory, again using the BCFW recursion to prove the dual conformal symmetry. Furthermore, we demonstrate that compact analytical formulae for tree-superamplitudes in N=(1,1) SYM can be obtained from a numerical implementation of the supersymmetric BCFW recursion relation. We derive compact manifestly dual conformal representations of the five- and six-point superamplitudes as well as arbitrary multiplicity formulae valid for certain classes of superamplitudes related to ultra-helicity-violating massive amplitudes in 4d. We study massive tree superamplitudes on the Coulomb branch of the N=4 SYM theory from dimensional reduction of the massless superamplitudes of the six-dimensional N=(1,1) SYM theory. We exploit this correspondence to construct the super-Poincare and enhanced dual conformal symmetries of massive tree superamplitudes in N=4 SYM theory which are shown to close into a finite dimensional algebra of Yangian type. Finally, we address the fascinating possibility of uplifting massless 4d superamplitudes to 6d massless superamplitudes proposed by Huang. We confirm the uplift for multiplicities up to eight but show that finding the uplift is highly non-trivial and in fact not of a practical use for multiplicities larger than five.

description: Die (Re-)Konstruktion und räumliche Situierung kollektiver Identitäten stellt einen zentralen Bestand­teil altertumswissenschaftlicher Praxis dar. Doch obwohl Karten als Analyseinstrument und Darstel­lungsmethode eine wesentliche Rolle spielen, sind ihre Implikationen und Effekte bislang nur unzurei­chend vergleichend untersucht. Dabei hat man in den Altertumswissenschaften nicht nur immer wieder versucht, geographische Informationen über die Herkunft und Verbreitung von Sprachen, Artefakten, Völkern oder Kulturen narrativ darzustellen, sondern eben auch karto­gra-phisch zu fixieren. Solche kartographischen Identitätskonstruktionen können als direkte oder auch indizielle Erfassung historischer Handlungsträger verstanden werden. So gibt es Karten, auf denen etwa Völker oder Sprachgruppen unmittelbar geographisch situiert werden; andere Karten geben lediglich die geographische Verteilung bestimmter Merkmale (linguistische Charakteristika, materielle Objekte etc.) wieder, die als Hinweis auf die Präsenz oder gar Handlungen kollektiver Identitäten angesehen werden. In diesem Sammelband werden Kartierungspraktiken aus unter­schied­lichen fachlichen Perspektiven in ihren verschiedenen Ausprägungen und Transformationen kritisch beleuchtet.
Reconstructing the Thermal Sunyaev-Zel'dovich Effect in 3D

description: The thermal Sunyaev-Zel'dovich (tSZ) effect measures the line-of-sight projection of the thermal pressure of free electrons and lacks any redshift information. By cross correlating the tSZ effect with an external cosmological tracer we can recover a good fraction of this lost information. Weak lensing (WL) is thought to provide an unbiased probe of the dark Universe, with many WL surveys having sky coverage that overlaps with tSZ surveys. Generalising the tomographic approach, we advocate the use of the spherical Fourier-Bessel (sFB) expansion to perform an analysis of the cross-correlation between the projected (2D) tSZ Compton $y$-parameter maps and 3D weak lensing convergence maps. We use redshift dependent linear biasing and the halo model as a tool to investigate the tSZ-WL cross-correlations in 3D. We use the Press-Schechter (PS) and the Sheth-Tormen (ST) mass-functions in our calculations, finding that the results are quite sensitive to detailed modelling. We provide detailed analysis of surveys with photometric and spectroscopic redshifts. The signal-to-noise (S/N) of the cross-spectra $\mathcal{C}_{\ell} (k)$ for individual 3D modes, defined by the radial and tangential wave numbers $(k;\ell)$, remains comparable to, but below, unity though optimal binning is expected to improve this. The results presented can be generalised to analyse other CMB secondaries, such as the kinetic Sunyaev-Zel'dovich (kSZ) effect.

Neutrinoless double-$β$ decay of ${}^{82}$Se in the shell model: beyond closure approximation

description: We recently proposed a new method to calculate the standard nuclear matrix elements for neutrinoless double-$β$ decay ($0νββ$) of ${}^{48}$Ca going beyond the closure approximation. Here we extend this analysis to the important case of ${}^{82}$Se, which was chosen as the base isotope for the upcoming SuperNEMO experiment. We demonstrate that using a mixed method that considers information from closure and non-closure approaches, one can get excellent convergence properties for the nuclear matrix elements, which allows one to avoid unmanageable computational costs. We show that in contrast with the closure approximation the mixed approach has a very weak dependence on the average closure energy. The matrix elements for the heavy neutrino-exchange mechanism that could contribute to the $0νββ$ decay of ${}^{82}$Se are also presented.

Die ethnische Komponente im Aufbau der antiken Karte
Creators: name: Marcotte, Didier
Publisher: name: Edition Topoi

description: Der vorliegende Beitrag untersucht die Rolle der ethnischen Aufteilung in den Raumerfassungen von Eratosthenes bis Ptolemaios. Er stellt die ursprüngliche Beziehung zwischen dem Verfahren des antiken Periplus und dem Aufbau der Karte dar und zeigt, inwieweit die Art und Weise der ‚Stamm für Stamm‘ angelegten Küstenbeschreibung die Grundlagen der Kartographie geprägt hat. Anhand von theoretischen Überlegungen des Strabo wird in diesem Aufsatz auch ein gewisses Misstrauen des griechischen Geographen, bzw. Kartographen gegenüber den politischen Daten hervorgehoben. Eine solche Haltung, die sich bei Strabo durch den Gebrauch des Begriffskairos (‚Umstände’, ‚ständi­ger Wandel’) äußert, kann z. B. erklären, dass die augusteische Aufteilung Italiens in Provinzen einen geringen Einfluss auf die Kartographie der kaiserlichen Zeit geübt hat.
