Dem Schicksal ein Schnippchen schlagen. Die Bibel als Versuch, die Komplexität menschlichen Daseins literarisch in den Griff zu bekommen
Creators: name: Herweg, Nikola
Publisher: name: KULT_online
Year: 2007

description: In dem 2005 erschienenem Buch über die Bibel als literarisches Meisterwerk versucht der Journalist und Übersetzer Hans-Peter Schmidt, die hebräische Bibel "so religiös unvoreingenommen wie möglich" (Klappentext) zu lesen. Schmidt fragt nach den Motiven und Strategien der Schöpfer der ‚literarischen Figur Gott’. Dabei konzentriert er sich auf eine textimmanente Interpretation. Gerade aber dort, wo er seine literarische Lesweise in den Kontext theologischer Exegese und historisch-kritischer Bibelinterpretation stellt, gewinnt seine Studie an Gewicht.

description: Autonomous air traffic management (ATM) operations for urban air mobility (UAM) will necessitate the use of distributed protocols for decentralized coordination between aircraft. As UAM operations are time-critical, it will be imperative to have formal guarantees of progress for the distributed protocols used in ATM. Under asynchronous settings, message transmission and processing delays are unbounded, making it impossible to provide deterministic bounds on the time required to make progress. We present an approach for formally guaranteeing timely progress in a Two-Phase Acknowledge distributed knowledge propagation protocol by probabilistically modeling the delays using theories of the Multicopy Two-Hop Relay protocol and the M/M/1 queue system. The guarantee states a probabilistic upper bound to the time for progress as a function of the probabilities of the total transmission and processing delays being less than two given values. We also showcase the development of a library of formal theories, that is tailored towards reasoning about timely progress in distributed protocols deployed in airborne networks, in the Athena proof assistant.

description: User reviews have an essential role in the success of the developed mobile apps. User reviews in the textual form are unstructured data, creating a very high complexity when processed for sentiment analysis. Previous approaches that have been used often ignore the context of reviews. In addition, the relatively small data makes the model overfitting. A new approach, BERT, has been introduced as a transfer learning model with a pre-trained model that has previously been trained to have a better context representation. This study examines the effectiveness of fine-tuning BERT for sentiment analysis using two different pre-trained models. Besides the multilingual pre-trained model, we use the pre-trained model that only has been trained in Indonesian. The dataset used is Indonesian user reviews of the ten best apps in 2020 in Google Play sites. We also perform hyper-parameter tuning to find the optimum trained model. Two training data labeling approaches were also tested to determine the effectiveness of the model, which is score-based and lexicon-based. The experimental results show that pre-trained models trained in Indonesian have better average accuracy on lexicon-based data. The pre-trained Indonesian model highest accuracy is 84%, with 25 epochs and a training time of 24 minutes. These results are better than all of the machine learning and multilingual pre-trained models.

description: We use the global embedding of a black hole spacetime into a higher dimensional flat spacetime to define a local temperature for observers in free fall outside a static black hole. The local free-fall temperature remains finite at the event horizon and in asymptotically flat spacetime it approaches the Hawking temperature at spatial infinity. Freely falling observers outside an AdS black hole do not see any high-temperature thermal radiation even if the Hawking temperature of such black holes can be arbitrarily high.

Correlation potential and ladder diagrams

Subjects: subject: Atomic Physics (physics.atom-ph)

description: The all-order correlation potential method of accurate atomic structure calculations for atoms with one external electron is extended to include one more class of correlation diagrams to all orders. These are the so-called ladder diagrams which describe residual Coulomb interaction between an external electron and atomic core. This is in addition to the screening of Coulomb interaction by core electrons and the hole-particle interaction in the core polarization operator which are also included in all orders. Calculations of the energies of the lowest $s$, $p$ and $d$ states of cesium and thallium show that inclusion of the ladder diagrams leads to significant improvement of the accuracy of the calculations. The discrepancy between theoretical and experimental energies is reduced to a small fraction of a per cent in all cases. This widens the range of atoms and atomic states for which the correlation potential method can produce very accurate results.

Phosphatidylcholine biosynthesis in hypercholesterolemic rats
Creators: name: Lim, Princeton H.
Publisher: name: University of British Columbia
Year: 2010

description: The regulation of the rate of phosphatidylcholine biosynthesis was investigated in the present study. Rats fed a high cholesterol/cholate diet had elevated levels of plasma cholesterol and phospholipids and this suggested that the rate of phosphatidylcholine biosynthesis might be altered during hypercholesterolemia. The activities of the enzymes of phosphatidylcholine biosynthesis were measured and the activities of phosphocholine cytidylyltransferase in cytosol and microsomes were increased 2- to 3-fold in the livers from hypercholesterolemia rats when compared to controls. The activities of choline kinase, phosphocholine-transferase and phosphatidylethanolamine methyltransferases, however, were unchanged. The stimulation of the cytidylyltransferase was not due to an adaptive increase in the quantity of enzyme and results suggested that a phospholipid modulator was responsible for the activation of the enzyme. The rate of phosphatidylcholine biosynthesis in the liver was measured after intraportal injection of labelled choline. The estimated rate of synthesis was 2- to 3-fold higher in the hypercholesterolemia rats and this correlated with the 2- to 3-fold stimulation of phosphocholine cytidylyltransferase activity. The results clearly showed that the cytidylyltransferase activity in the liver was rate-limiting in the de novo synthesis of phosphatidylcholine during hypercholesterolemia and strongly indicated that the increase in plasma phospholipids during hypercholesterolemia was, at least in part, the result of increased synthesis of phosphatidylcholine in the liver.

description: We investigate the evolution of high redshift seed black hole masses at late times and their observational signatures. The massive black hole seeds studied here form at extremely high redshifts from the direct collapse of pre-galactic gas discs. Populating dark matter halos with seeds formed in this way, we follow the mass assembly of these black holes to the present time using a Monte-Carlo merger tree. Using this machinery we predict the black hole mass function at high redshifts and at the present time; the integrated mass density of black holes and the luminosity function of accreting black holes as a function of redshift. These predictions are made for a set of three seed models with varying black hole formation efficiency. Given the accuracy of current observational constraints, all 3 models can be adequately fit. Discrimination between the models appears predominantly at the low mass end of the present day black hole mass function which is not observationally well constrained. However, all our models predict that low surface brightness, bulgeless galaxies with large discs are least likely to be sites for the formation of massive seed black holes at high redshifts. The efficiency of seed formation at high redshifts has a direct influence on the black hole occupation fraction in galaxies at z=0. This effect is more pronounced for low mass galaxies. This is the key discriminant between the models studied here and the Population III remnant seed model. We find that there exists a population of low mass galaxies that do not host nuclear black holes. Our prediction of the shape of the black hole mass - velocity dispersion relation at the low mass end is in agreement with the recent observational determination from the census of low mass galaxies in the Virgo cluster.

description: Single-line spectroscopic binaries recently contribute to the stellar-mass black hole discovery, independently of the X-ray transient method. We report the identification of a single-line binary system LTD064402+245919, with an orbital period of 14.50 days. The observed component is a subgiant with a mass of 2.77$\pm$0.68M$_{\odot}$, radius 15.5$\pm$2.5R$_{\odot}$, effective temperature $T_{\rm eff}$ 4500$\pm$200K, and surface gravity log\emph{g} 2.5$\pm$0.25dex. The discovery makes use of the LAMOST time-domain (LAMOST-TD) and ZTF survey. Our general-purpose software pipeline applies the Lomb-Scargle periodogram to determine the orbital period and uses machine-learning to classify the variable type from the folded light curves. We apply a combined model to estimate the orbital parameters from both the light and radial velocity curves, taking constraints on the primary star mass, mass function, and detection limit of secondary luminosity into consideration. We obtain a radial velocity semi-amplitude of 44.6$\pm$1.5 km s$^{-1}$, mass ratio of 0.73$\pm$0.07, and an undetected component mass of 2.02$\pm$0.49M$_{\odot}$ when the type of the undetected component is not set. We conclude that the inclination is not well constrained, and that the secondary mass is larger than 1M$_{\odot}$ when the undetected component is modelled as a compact object. According to our investigations using an MCMC simulation, increasing the spectra SNR by a factor of 3 would enable the secondary light to be distinguished (if present). The algorithm and software in this work are able to serve as general-purpose tools for the identification of compact objects quiescent in X-rays.

description: Star-formation within galaxies appears on multiple scales, from spiral structure, to OB associations, to individual star clusters, and often sub-structure within these clusters. This multitude of scales calls for objective methods to find and classify star-forming regions, regardless of spatial size. To this end, we present an analysis of star-forming groups in the local group spiral galaxy M33, based on a new implementation of the Minimum Spanning Tree (MST) method. Unlike previous studies which limited themselves to a single spatial scale, we study star-forming structures from the effective resolution limit (~20pc) to kpc scales. We find evidence for a continuum of star-forming group sizes, from pc to kpc scales. We do not find a characteristic scale for OB associations, unlike that found in previous studies, and we suggest that the appearance of such a scale was caused by spatial resolution and selection effects. The luminosity function of the groups is found to be well represented by a power-law with an index, -2, similar to that found for clusters and GMCs. Additionally, the groups follow a similar mass-radius relation as GMCs. The size distribution of the groups is best described by a log-normal distribution and we show that within a hierarchical distribution, if a scale is selected to find structure, the resulting size distribution will have a log-normal distribution. We find an abrupt drop of the number of groups outside a galactic radius of ~4kpc, suggesting a change in the structure of the star-forming ISM, possibly reflected in the lack of GMCs beyond this radius.

Population III Wolf-Rayet Stars in the CAK Regime

Publisher: name: arXiv
Year: 2007
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: Wolf-Rayet (WR) stars near solar metallicity are believed to be driven by radiation pressure on the UV spectral lines of metal ions. As the metallicity decreases so does the line opacity, therefore the mass-loss rate. However, since the composition of a WR atmosphere is determined by the burn products of the core, there is a lower limit on the line opacity -- and therefore the mass-loss rate -- of a WR star, even in a star with zero initial metallicity. This presentation is the result of attempt to calculate the mass-loss rate of a Population III-type WO star using a modified version of the CAK approximation. I find that n_e greater than or equal to 10^{13} cm^{-3} and Gamma between 0.5 and 0.7 give the most plausible results, with the resulting mass-loss rate between 2x10^{-9} M_sun yr^{-1} and 3x10^{-8} M_sun yr^{-1}.

description: The proposed cyclotron gas-stopping scheme for the efficient thermalization of intense rare isotope beams is examined. Simulations expand on previous studies and expose many complications of such an apparatus arising from physical effects not accounted for properly in previous work. The previously proposed cyclotron gas-stopper geometry is found to have a near null efficiency, but extended simulations suggest that a device with a much larger pole gap could achieve a stopping efficiency approaching roughly 90% and at least a 10 times larger acceptance. However, some of the advantages that were incorrectly predicted in previous simulations for high intensity operation of this device are compromised.

Influence of the polarization in grazing scattering of fast hellium atoms from LiF(001) surfaces

description: Grazing scattering of neutral atoms from insulator surfaces is investigated in the intermediate velocity range, in which interference effects have been recently observed. To describe this process we introduce a distorted-wave method, based on the use of the eikonal wave function, which takes into account the phase of the scattering state along the classical projectile path. The eikonal theory is applied to evaluate the angular distribution of few keV helium atoms after impinging on a LiF(001) surface along low-index crystallographic directions. The interest focuses on the role played by the projectile polarization produced by cations and anions of the crystal surface. For the considered collision system we found a polarization channel, corresponding to the direction <110>, which is affected by this effect, while for incidence in the direction <100> the polarization contribution is nearly negligible. The proposed eikonal approach, including polarization effects, provides angular projectile spectra in good agreement with the experimental data.

description: Multivariate statistics are often available as well as necessary in hypothesis tests. We study how to use such statistics to control not only false discovery rate (FDR) but also positive FDR (pFDR) with good power. We show that FDR can be controlled through nested regions of multivariate $p$-values of test statistics. If the distributions of the test statistics are known, then the regions can be constructed explicitly to achieve FDR control with maximum power among procedures satisfying certain conditions. On the other hand, our focus is where the distributions are only partially known. Under certain conditions, a type of nested regions are proposed and shown to attain (p)FDR control with asymptotically maximum power as the pFDR control level approaches its attainable limit. The procedure based on the nested regions is compared with those based on other nested regions that are easier to construct as well as those based on more straightforward combinations of the test statistics.

description: Most of the properties of black holes can be mimicked by horizonless compact objects such as gravastars and boson stars. We show that these ultra-compact objects develop a strong ergoregion instability when rapidly spinning. Instability timescales can be of the order of 0.1 seconds to 1 week for objects with mass M=1-10^6 solar masses and angular momentum J> 0.4 M^2. This provides a strong indication that ultra-compact objects with large rotation are black holes. Explosive events due to ergoregion instability have a well-defined gravitational-wave signature. These events could be detected by next-generation gravitational-wave detectors such as Advanced LIGO or LISA.

description: (Abridged) We present a search for the progenitor star of the Type Ic Supernova 2002ap in deep, high quality pre-explosion observations taken with the Canada-France-Hawaii Telescope (CFHT). Aligning high-resolution Hubble Space Telescope (HST) observations of the supernova itself with the archival CFHT images allowed us to pinpoint the location of the progenitor site on the ground based observations. We find that a source visible in the B and R band pre-explosion images close to the position of the SN is (1) not coincident with the SN position within the uncertainties of our relative astrometry, and (2) is still visible ~ 4.7 yrs post-explosion in late-time observations taken with the William Herschel Telescope. We therefore conclude that it is not the progenitor of SN 2002ap. Comparing our luminosity limits with stellar models of single stars at appropriate metallicity (Z=0.008) we conclude that any single star progenitor must have experienced at least twice the standard mass loss rates during pre-Wolf-Rayet evolution, been initially > 30-40M(Sun) and exploded as a Wolf-Rayet star of final mass 10-12M(Sun). Alternatively an initially less massive progenitor may have evolved in an interacting binary system. We constrain any possible binary companion to a main sequence star of < 20M(Sun), a neutron star or a black hole. By combining the pre-explosion limits with the ejecta mass estimates and constraints from X-ray and radio observations we conclude that any binary interaction most likely occurred as Case B mass transfer, either with or without a subsequent common envelope evolution phase.

Metabolic studies on the locust rectum
Creators: name: Chamberlin, Mary Ella
Publisher: name: University of British Columbia
Year: 2010

description: The in vitro, short-circuited locust rectum actively transports chloride. This electrogenic transport is energized by aerobic metabolism, based primarily upon proline oxidation. Isolated rectal mito-chondrialoxidize a variety of substrates, but the highest state 3 rate of 0₂ consumption occurs when proline is the stubstrate. An enzyme profile of the rectal tissue indicates that the rectum can oxidize amino acids and carbohydrates but has a limited capacity for lipid oxidation. Analysis of the two fluids which bathe the rectum in vivo, the hemolymph and the Malpighian tubule fluid, reveals that proline is present in bothethe hemolymph (12-15 mM) and tubule fluid (38-43 mM). Although glycine is also found in high concentration in the hemolymph (13-17 mM), far lower concentrations of this and other amino acids are found in the Malpighian tubule fluid. Glucose is also found in the hemolymph (2 mM) and Malpighian tubule fluid (4 mM). The high concentraion of proline in the tubule fluid indicated that this amino acid may be actively transported by tubules. This prediction was confirmed by experiments with in vitro tubules. This is the first evidence of aetive secretion of a metabolically useful compound by insect Malpighian tubules. Experiments involving the measurement of short-circuit current (Isc) across the locust rectum were also performed. The results of these experiments indicate that high levels (50 mM) of proline stimulate the Isc of substrate-depleted recta better than high levels of any other substrate tested. Physiological levels of proline also cause a large increase in the Isc of substrate-depleted recta, while physiological levels of glucose produce a much smaller stimulation. Over 90% of the Isc stimulation can be produced by adding proline (15 mM) solely to the lumen side of the tissue. Other studies were performed to estimate the metabolic cost of actively transporting chloride. The oxygen consumption of chloride-depleted recta were measured before and after reintroduction of chloride. From these data a Cl⁻/ATP ratio of 3-4 was obtained. Further calculations indicated that tissue proline oxidation is sufficient to energize active chloride transport. The results outlined here suggest that in vivo, the rectal lumen is bathed with a high concentration of proline which can be readily oxidized by the rectal mitochondria to support the work of actively transporting chloride.

description: The efficacy of machine learning models is typically determined by computing their accuracy on test data sets. However, this may often be misleading, since the test data may not be representative of the problem that is being studied. With QuantifyML we aim to precisely quantify the extent to which machine learning models have learned and generalized from the given data. Given a trained model, QuantifyML translates it into a C program and feeds it to the CBMC model checker to produce a formula in Conjunctive Normal Form (CNF). The formula is analyzed with off-the-shelf model counters to obtain precise counts with respect to different model behavior. QuantifyML enables i) evaluating learnability by comparing the counts for the outputs to ground truth, expressed as logical predicates, ii) comparing the performance of models built with different machine learning algorithms (decision-trees vs. neural networks), and iii) quantifying the safety and robustness of models.

description: Torsional harmonic cantilevers allow measurement of time varying tip-sample forces in tapping-mode atomic force microscopy. Accuracy of these force measurements is important for quantitative nanomechanical measurements. Here we demonstrate a method to convert the torsional deflection signals into a calibrated force waveform with the use of non-linear dynamical response of the tapping cantilever. Specifically the transitions between steady oscillation regimes are used to calibrate the torsional deflection signals.

description: The nuclear symmetry energy plays a key role in determining the equation of state of dense, neutron-rich matter, which governs the properties of both terrestrial nuclear matter as well as astrophysical neutron stars. A recent measurement of the neutron skin thickness from the PREX collaboration has lead to new constraints on the slope of the nuclear symmetry energy, L, which can be directly compared to inferences from gravitational-wave observations of the first binary neutron star merger inspiral, GW170817 In this paper, we explore a new regime for potentially constraining the slope, L, of the nuclear symmetry energy with future gravitational wave events: the post-merger phase a binary neutron star coalescence. In particular, we go beyond the inspiral phase, where imprints of the slope parameter L may be inferred from measurements of the tidal deformability, to consider imprints on the post-merger dynamics, gravitational wave emission, and dynamical mass ejection. To this end, we perform a set of targeted neutron star merger simulations in full general relativity using new finite-temperature equations of state, which systematically vary L. We find that the post-merger dynamics and gravitational wave emission are mostly insensitive to the slope of the nuclear symmetry energy. In contrast, we find that dynamical mass ejection contains a weak imprint of L, with large values of L leading to systematically enhanced ejecta.

description: Insectonomy is an evolving interdisciplinary initiative that redefines how we see, value, and manage insects in agri-food systems. Rooted in science and expanded through art, it recognizes insects not merely as resources, but as vital agents in socio-ecological resilience. By integrating conservation, pest control, wild gathering, and farming strategies, Insectonomy invites collaboration across research, policy, local knowledge, and creative practices.

Facing climate uncertainty, biodiversity loss, and broken food systems, this poster brings together voices from science, economics, policy, and art to explore insects' multifaceted contributions—from pollination to cultural heritage. Marcel Dicke emphasizes stakeholder perceptions, Menale Kassie highlights economic viability, Thaïs Nuñez questions trade and biodiversity, Olivier Dangles reframes resilience, and David Giron calls for stronger science-policy-society bridges.

Crucially, Hypersystms—as proposed by Umberto Diecinove—adds a philosophical and aesthetic layer. Through unsupervised machine learning and data visualization, insect ecosystem services are revealed as vast, decentralized networks—what Timothy Morton calls hyperobjects: complex, distributed realities that transcend human-scale perception. This perspective invites us to step beyond anthropocentric systems and embrace coexistence within a larger ecological matrix.

Together, Insectonomy and Hypersystms propose a transformation: from managing insects to co-evolving with them. It is an invitation to redesign our agri-food systems through empathy, complexity, and imagination.

description: Controlling magnetic order in magnetic topological insulators (MTIs) is a key to developing spintronic applications with MTIs, and is commonly achieved by changing the magnetic doping concentration, which inevitably affects spin-orbit-coupling strength and the very topological properties. Here, we demonstrate tunable magnetic properties in topological heterostructures over a wide range, from a ferromagnetic phase with Curie temperature of around 100 K all the way to a paramagnetic phase, while keeping the overall chemical composition the same, by controlling the thickness of non-magnetic spacer layers between two atomically-thin magnetic layers. This work showcases that spacer-layer control is a powerful tool to manipulate magneto-topological functionalities in MTI heterostructures. Furthermore, the interaction between the MTI and the Cr2O3 buffer layers also led to robust topological Hall effect surviving up to a record-high 6 T of magnetic field, shedding light on the critical role of interfacial layers in thin film topological materials.

description: Building on earlier work, we discuss a general framework for exploring the cosmological dynamics of Higher Order Theories of Gravity. We show that once the theory of gravity has been specified, the cosmological equations can be written as a first-order autonomous system and we give several examples which illustrate the utility of our method. We also discuss a number of results which have appeared recently in the literature.

description: The nonperturbative nature of nucleon-nucleon interactions evolved to low momentum has recently been investigated in free space and at finite density using Weinberg eigenvalues as a diagnostic. This analysis is extended here to the in-medium eigenvalues near the Fermi surface to study pairing. For a fixed value of density and cutoff Lambda, the eigenvalues increase arbitrarily in magnitude close to the Fermi surface, signaling the pairing instability. When using normal-phase propagators, the Weinberg analysis with complex energies becomes a form of stability analysis and the pairing gap can be estimated from the largest attractive eigenvalue. With Nambu-Gorkov Green's functions, the largest attractive eigenvalue goes to unity close to the Fermi surface, indicating the presence of bound states (Cooper pairs), and the corresponding eigenvector leads to the self-consistent gap function.
