Schutzlos ausgeliefert. Kultur und Natur in Pompeji

description: Natur besiegt Kultur, bewahrt sie aber auch: Das zeigen deutlich die Ausgrabungen in Pompeji. Der Ausbruch des Vesuvs im Jahr 79 n. Chr. bereitete dem Leben in der römischen Kleinstadt ein jähes Ende – mit all ihrer Pracht, die rund 2.000 Jahre später konserviert besichtigt werden kann. Heute ist die Kultur Pompejis größter Feind: Denn mehr als drei Millionen Besucher jährlich, die über antike Bürgersteige wandern, Fresken berühren und Müll hinterlassen, sind ein konservatorischer Super-GAU. Einmal freigelegt, sind archäologische Funde, die Jahrhunderte oder gar Jahrtausende unter Erde oder Asche begraben und damit geschützt waren, konstant gefährdet.

description: The influence of the environment on gas surface density and star formation efficiency of cluster spiral galaxies is investigated. We extend previous work on radial profiles by a pixel-to pixel analysis looking for asymmetries due to environmental interactions. The star formation rate is derived from GALEX UV and Spitzer total infrared data. As in field galaxies, the star formation rate for most Virgo galaxies is approximately proportional to the molecular gas mass. Except for NGC 4438, the cluster environment does not affect the star formation efficiency with respect to the molecular gas. Gas truncation is not associated with major changes in the total gas surface density distribution of the inner disk of Virgo spiral galaxies. In three galaxies, possible increases in the molecular fraction and the star formation efficiency with respect to the total gas, of factors of 1.5 to 2, are observed on the windward side of the galactic disk. A significant increase of the star formation efficiency with respect to the molecular gas content on the windward side of ram pressure-stripped galaxies is not observed. The ram-pressure stripped extraplanar gas of 3 highly inclined spiral galaxies shows a depressed star formation efficiency with respect to the total gas, and one of them (NGC 4438) shows a depressed rate even with respect to the molecular gas. The interpretation is that stripped gas loses the gravitational confinement and associated pressure of the galactic disk, and the gas flow is diverging, so the gas density decreases and the star formation rate drops. However, the stripped extraplanar gas in one highly inclined galaxy (NGC 4569) shows a normal star formation efficiency with respect to the total gas. We propose this galaxy is different because it is observed long after peak pressure, and its extraplanar gas is now in a converging flow as it resettles back into the disk.

Recht, Gerechtigkeit und Moral. Die Debatte um Naturrecht und Rechtspositivismus
Creators: name: Borowski, Martin
Publisher: name: Ruperto Carola
Year: 2019

description: Muss Recht notwendig gerecht sein? Der Umgang mit dieser Frage zeigt einen zentralen Unterschied zwischen Naturrecht und Rechtspositivismus auf: Während das Naturrecht von einem notwendigen Zusammenhang zwischen Recht und Moral ausgeht, existiert nach dem Rechtspositivismus keine solche Verbindung. Praktische Bedeutsamkeit erlangt diese Unterscheidung vor allem bei der Überwindung der Folgen von Unrechtssystemen. Hier hat der Heidelberger Rechtsphilosoph Gustav Radbruch mit seiner „Radbruchschen Formel“ Maßstäbe gesetzt, die auch beim Umgang mit der deutschen Vergangenheit im 20. Jahrhundert zum Tragen kamen.

description: Impatiens glandulifera, an annual species native to the Himalayas, is the tallest annual plant in Europe, where it has become invasive and destabilises riverbanks. This study explored between- and within-site trait variation in the invasive range of I. glandulifera to identify trait relationships that underlie the large size and local invasion success of this species. Leaf chlorophyll content, vegetative growth traits (plant height, leaf length, leaf width, number of side branches, leaves and nodes), the number of reproductive units (sum of flower buds, flowers and seed pods) and seed pod length were determined for five I. glandulifera stands in the south-west of Ireland. Plant vegetative growth traits and the number of reproductive units were positively correlated, with the highest trait values observed at a shaded site with high disturbance. Chlorophyll content in the upper leaves declined with an increasing number of reproductive units at sites with low soil nitrogen, suggesting that nutrient allocation to the reproductive sinks is prioritised over photosynthetic capacity of the upper leaves. The ability to grow to a remarkably large size under shaded, disturbed conditions contributes to the invasion success of I. glandulifera.

description: To comprehend the mechanical behavior of a polycrystalline material, an in-depth analysis of individual grain boundary (GB) and dislocation interactions is of prime importance. In the past decade, nanoindentation emerged as a powerful tool to study the local mechanical response in the vicinity of the GB. The improved instrumentation and test protocols allow to capture various GB–dislocation interactions during the nanoindentation in the form of strain bursts on the load–displacement curve. Moreover, the interaction of the plastic zone with the GB provides important insight into the dislocation transmission effects of distinct grain boundaries. Of great importance for the analysis and interpretation of the observed effects are microstructural investigations and computational approaches. This review paper focused on recent advances in the dislocation–GB interactions and underlying mechanisms studied via nanoindentation, which includes GB pop-in phenomenon, localized grain movement under ambient conditions, and an analysis of the slip transfer mechanism using theoretical treatments and simulations.

description: Using the isospin dependent quantum molecular dynamics model, we study the effect of charge asymmetry and isospin dependent cross-section on $\frac{dN}{d()}$ and $\frac{dN}{p_tdp_t}$. Simulations have been carried out for the reactions of $^{124}X_{m}+^{124}X_{m}$, where m = (47, 50 and 59) and $^{40}S_{16}+^{40}S_{16}$. Our study shows that these parameters depend strongly on the isospin of cross-section and charge asymmetry. The distribution of nucleons and fragments is not symmetric around the beam axis.

description: En los libros del artista y escritor puertorriqueño Eduardo Lalo (Cuba, 1960) se plasma una ‘contra -­‐‑ escritura geográfica’ de su país y de su ciudad, San Juan de Puerto Rico, metrópolis que al haber sido colonizada por Estados Unidos se ha trasformado en texto urbano especular de las ciudades norteamericanas. La urbe alternativa de Lalo cobra espesor a medida que un observador – n arrador recorre sus calles escribiendo, dibujando o haciendo fotos para liberarla del estatuto de imagen turística estereotipada. Gracias a un entrelazado iconotextual de formas identitarias, la ciudad se vuelve experiencia sensible que deja entrever las c icatrices y las huellas de la verdadera San Juan: su genius loci.

description: Za cel niniejszego artykułu należy uznać przedstawienie referendum lokalnego jako jednego z dwóch wariantów demokracji bezpośredniej, które powinno sprzyjać zwiększonej aktywności wspólnoty samorządowej. Drugim wariantem bezpośredniej władzy sprawowanej przez mieszkańców w j.s.t. są powszechne wybory do organów tejże jednostki. Partycypacja społeczna jest dziś szczególnie pożądana w związku z faktem, że to obywatele sprawują największy wymiar władzy nie tylko w j.s.t., lecz w całej Rzeczypospolitej Polskiej, zgodnie z treścią art. 4 Konstytucji RP. Stanowi ona aktywny udział obywateli w życiu wspólnoty oraz możliwość zaangażowania się w szeroko pojęte sprawy lokalne. W opracowaniu przedstawiono, z pominięciem szczegółowej analizy, także istotę i cel referendum lokalnego oraz partycypacji obywatelskiej. Istotne jest również rozważenie danych statystycznych, dotyczących liczby referendów odwoławczych organu wykonawczego gminy w latach 2002-2023. W tym celu zgłębić należy zarówno aspekty prawne, jak i społeczne. Uwaga zostanie skupiona wyłącznie na odwołaniu organu wykonawczego gminy, ponieważ to gmina jest podstawową j.s.t.1 oraz tylko tam występuje jednoosobowy organ wykonawczy, który ponadto jest wybierany w wyborach bezpośrednich.

description: : Despite the broad distribution of several species in Gleicheniaceae in the neotropical region, Diplopterygium is the only genus having a restricted distribution. Species of Gleicheniaceae occupy open (including anthropogenic) habitats and produce large amounts of wind-dispersed propagules – so why does Diplopterygium bancroftii, the only neotropical species in the genus, have a restricted distribution? : We investigated if the restricted distribution of Diplopterygium in the Neotropics reflected the absence of suitable areas for the establishment. : We used species distribution modeling to identify suitability areas during different periods of the Pleistocene (Last Glacial Maximum and Last Interglacial), the Holocene, and the present. : The environmental suitability model at the present time corroborated the current distribution of D. bancroftii, and also evidenced additional suitable potential areas where the species has so far not been recorded, especially in eastern Brazil. In projections of the past, no connectivity was observed between suitable areas in the Andes and eastern Brazil. : As neither the dispersal ability nor the absence of suitable areas at the present time or in the past were limiting factors to the range expansion of Diplopterygium, we discuss possible migration barriers and propose a hypothesis for its colonization history in the Neotropics.

The most important results of our investigations in this field are also listed. All these investigations indicate that the broad Fe Kα line is a powerful tool for studying the properties of the supermassive black holes (such as their masses and spins), space-time geometry (metric) in their vicinity, their accretion physics, probing the effects of their strong gravitational fields, and for testing the certain predictions of General Relativity.

description: We present high-precision radial velocity (RV) observations of four solar-type (F7-G5) stars - HD 79498, HD 155358, HD 197037, and HD 220773 - taken as part of the McDonald Observatory Planet Search Program. For each of these stars, we see evidence of Keplerian motion caused by the presence of one or more gas giant planets in long-period orbits. We derive orbital parameters for each system, and note the properties (composition, activity, etc.) of the host stars. While we have previously announced the two-gas-giant HD 155358 system, we now report a shorter period for planet c. This new period is consistent with the planets being trapped in mutual 2:1 mean-motion resonance. We therefore perform an in-depth stability analysis, placing additional constraints on the orbital parameters of the planets. These results demonstrate the excellent long-term RV stability of the spectrometers on both the Harlan J. Smith 2.7 m telescope and the Hobby-Eberly telescope.

The Origin and Distribution of Cold Gas in the Halo of a Milky Way-Mass Galaxy

description: We analyze an adaptive mesh refinement hydrodynamic cosmological simulation of a Milky Way-sized galaxy to study the cold gas in the halo. HI observations of the Milky Way and other nearby spirals have revealed the presence of such gas in the form of clouds and other extended structures, which indicates on-going accretion. We use a high-resolution simulation (136-272 pc throughout) to study the distribution of cold gas in the halo, compare it with observations, and examine its origin. The amount (10^8 Msun in HI), covering fraction, and spatial distribution of the cold halo gas around the simulated galaxy at z=0 are consistent with existing observations. At z=0 the HI mass accretion rate onto the disk is 0.2 Msun/yr. We track the histories of the 20 satellites that are detected in HI in the redshift interval 0.5>z>0 and find that most of them are losing gas, with a median mass loss rate per satellite of 3.1 x 10^{-3} Msun/yr. This stripped gas is a significant component of the HI gas seen in the simulation. In addition, we see filamentary material coming into the halo from the IGM at all redshifts. Most of this gas does not make it directly to the disk, but part of the gas in these structures is able to cool and form clouds. The metallicity of the gas allows us to distinguish between filamentary flows and satellite gas. We find that the former accounts for at least 25-75% of the cold gas in the halo seen at any redshift analyzed here. Placing constraints on cloud formation mechanisms allows us to better understand how galaxies accrete gas and fuel star formation at z=0.

description: All‐solid‐state batteries promise higher energy and power densities as well as increased safety compared to lithium‐ion batteries by using non‐flammable solid electrolytes and metallic lithium as the anode. Ensuring permanent and close contact between the components and individual particles is crucial for long‐term operation of a solid‐state cell. This study investigates the particle size dependent compression mechanics and ionic conductivity of the mechanically soft thiophosphate solid electrolyte tetragonal Li₇SiPS₈ (t‐LiSiPS) under pressure. The effect of stack and pelletizing pressure is demonstrated as a powerful tool to influence the microstructure and, hence, ionic conductivity of t‐LiSiPS. Heckel analysis for granular powder compression reveals distinct pressure regimes, which differently impact the Li ion conductivity. The pelletizing process is simulated using the discrete element method followed by finite volume analysis to disentangle the effects of pressure‐dependent microstructure evolution from atomistic activation volume effects. Furthermore, it is found that the relative density of a tablet is a weaker descriptor for the sample's impedance compared to the particle size distribution. The multiscale experimental and theoretical study thus captures both atomistic and microstructural effects of pressure on the ionic conductivity, thus emphasizing the importance of microstructure, particle size distribution and pressure control in solid electrolytes.

description: We investigate the Faraday rotation measure (RM) due to the intergalactic magnetic field (IGMF) through the cosmic web up to cosmological distances, using a model IGMF based on turbulence dynamo in the large-scale structure of the universe. By stacking the IGMF and gas density data up to redshift $z=5$ and taking account of the redshift distribution of polarized background radio sources against which the RM is measured, we simulate the sky map of the RM. The contribution from galaxy clusters is subtracted from the map, based on several different criteria of X-ray brightness and temperature. Our findings are as follows. The distribution of RM for radio sources of different redshifts shows that the root-mean-square (rms) value increases with redshift and saturates for $z \ga 1$. The saturated value is RM$_{\rm rms} \approx$ several ${\rm rad m^{-2}}$. The probability distribution function of $|{\rm RM}|$ follows the lognormal distribution. The power spectrum has a broad plateau over the angular scale of $\sim 1 - 0.1^\circ$ with a peak around $\sim 0.15^\circ$. The second-order structure function has a flat profile in the angular separation of $\ga 0.2^\circ$. Our results could provide useful insights for surveys to explore the IGMF with the Square Kilometer Array (SKA) and upcoming SKA pathfinders.

description: Coherent motion of cold atoms in a standing-wave field is interpreted as a propagation in two optical potentials. It is shown that the wave-packet dynamics can be either regular or chaotic with transitions between these potentials after passing field nodes. Manifestations of de Broglie-wave chaos are found in the behavior of the momentum and position probabilities and the Wigner function. The probability of those transitions depends on the ratio of the squared detuning to the Doppler shift and is large in that range of the parameters where the classical motion is shown to be chaotic.

Star Formation in Ram Pressure Stripped Tails

description: We investigate the impact of star formation and feedback on ram pressure stripping using high-resolution adaptive mesh simulations, building on a previous series of papers that systematically investigated stripping using a realistic model for the interstellar medium, but without star formation. We find that star formation does not significantly affect the rate at which stripping occurs, and only has a slight impact on the density and temperature distribution of the stripped gas, indicating that our previous (gas-only) results are unaffected. For our chosen (moderate) ram pressure strength, stripping acts to truncate star formation in the disk over a few hundred million years, and does not lead to a burst of star formation. Star formation in the bulge is slightly enhanced, but the resulting change in the bulge-to-disk ratio is insignificant. We find that stars do form in the tail, primarily from gas that is ablated from the disk and the cools and condenses in the turbulent wake. The star formation rate in the tail is low, and any contribution to the intracluster light is likely to be very small. We argue that star formation in the tail depends primarily on the pressure in the intracluster medium, rather than the ram pressure strength. Finally, we compare to observations of star formation in stripped tails, finding that many of the discrepancies between our simulation and observed wakes can be accounted for by different intracluster medium pressures.

description: We present a 1.16-\mum-radius disk cavity with ultrahigh quality (Q) factor by embedding the disk into a sunflower-type circular photonic crystal (CPC). The band gap of the CPC reduces the bending loss of the whispering-gallery mode of the disk, leading to a simulated Q of 10^7, at least one order of magnitude higher than a bare disk of the same size. The design is experimentally verified with a record high loaded Q of 7.4 \times 10^5 measured from an optimized device fabricated on a silicon-on-insulator substrate.

hepatic cell line

description: The increasing demand and hampered use of primary human hepatocytes for research purposes have urged scientists to search for alternative cell sources, such as immortalized hepatic cell lines. The aim of this study was to develop a human hepatic cell line using the combined overexpression of TERT and the cell cycle regulators cyclin D1 and mutant isoform CDK4R24C. Following transduction of adult human primary hepatocytes with the selected immortalization genes, cell growth was triggered and a cell line was established. When cultured under appropriate conditions, the cell line expressed several hepatocytic markers and liver-enriched transcription factors at the transcriptional and/or translational level, secreted liver-specific proteins and showed glycogen deposition. These results suggest that the immortalization strategy applied to primary human hepatocytes could generate a novel hepatic cell line that seems to retain some key hepatic characteristics.

description: We analyze how imperfections in single-photon detectors impact the characterization of photon-pair sources. We perform exact calculations to reveal the effects of multi-pair emissions and of noisy, non-unit efficiency, non photon-number resolving detections on the Cauchy-Schwarz parameter, on the second order auto-correlation and cross-correlation functions, and on the visibilities of both Hong-Ou-Mandel and Bell-like interferences. We consider sources producing either two-mode squeezed states or states with a Poissonian photon distribution. The proposed formulas are useful in practice to determine the impacts of multi-pair emissions and dark counts in standard tests used in quantum optics.

description: We apply Tsallis's q-indexed nonextensive entropy to formulate a random matrix theory (RMT), which may be suitable for systems with mixed regular-chaotic dynamics. We consider the super-extensive regime of q < 1. We obtain analytical expressions for the level-spacing distributions, which are strictly valid for 2 \times 2 random-matrix ensembles, as usually done in the standard RMT. We compare the results with spacing distributions, numerically calculated for random matrix ensembles describing a harmonic oscillator perturbed by Gaussian orthogonal and unitary ensembles.

description: The parity nonconserving longitudinal analyzing power A_L is calculated in elastic pp scattering at the energies below the approximate inelastic region T_lab = 350 MeV. The short-ranged heavy meson rho and omega exchanges as well as the longer-ranged two pion exchanges are considered as the mediators of the parity nonconserving interactions. The DDH "best" coupling values are used as the parity nonconserving meson-NN couplings. Also three different parity nonconserving two-pion exchange potentials by various authors are compared.

title: Revisiting the Fundamental Nature of Metal‐Ligand Bonding: An Impartial and Automated Fitting Procedure for Angular Overlap Model Parameters

description: The properties and reactivities of transition metal complexes are often discussed in terms of Ligand Field Theory (LFT), and with ab initio LFT a direct connection to quantum chemical wavefunctions was recently established. The Angular Overlap Model (AOM) is a widely used, ligand‐specific parameterization scheme of the ligand field splitting that has, however, been restricted by the availability and resolution of experimental data. Using ab initio LFT, we present here a generalised, symmetry‐independent and automated fitting procedure for AOM parameters that is even applicable to formally underdetermined or experimentally inaccessible systems. This method allows quantitative evaluations of assumptions commonly made in AOM applications, for example, transferability or the relative magnitudes of AOM parameters, and the response of the ligand field to structural or electronic changes. A two‐dimensional spectrochemical series of tetrahedral halido metalates ([MIIX₄]²⁻, M=Mn−Cu) served as a case study. A previously unknown linear relationship between the halide ligands’ chemical hardness and their AOM parameters was found. The impartial and automated procedure for identifying AOM parameters introduced here can be used to systematically improve our understanding of ligand–metal interactions in coordination complexes.

description: Using the linear response theory, the vibrational and dielectric properties are calculated for c-BN, w-BN and h-BN. Calculations of the zone-center optical-mode frequencies (including LO-TO splittings) are reported. All optic modes are identified and agreement of theory with experiment is excellent. The static dielectric tensor is decomposed into contributions arising from individual infrared-active phonon modes. It is found that all of the structures have a smaller lattice dielectric constant than that of electronic contribution. Finally, the infrared reflectance spectrums are presented. Our theoretical results indicate that w-BN shows a similar reflectivity spectrum as c-BN. It is difficult to tell the wurtzite structure from the zinc blende phase by IR spectroscopy.

Planetella gallarum

description: Planetella gallarum (Rübsaamen, 1899)
 Dichrona gallarum Rübsaamen 1899a: 542. Type locality: Germany.
 Type material. SYNTYPEs: 1J 8♀♀, in alcohol, Berlin, 30.i.–12.v.1896, (vial No. 380a, coll. ZMHB Berlin), examined.
 Additional material examined. DENMARK: East Jutland, Strandkaer (Biowide 060; Brunbjerg et al. 2019), 7.vi.2016, 1 J 1 ♀, reared from galls on Carex nigra var. recta, H. H. Bruun leg., specimens after DNA extraction, prepared on slides, No. PLA 6a, PLA 6b (coll. JSL-UOC). 1 larva: the same data, specimen after DNA extraction, No. PLA 6c (coll. JSL-UOC); 1 larva: West Jutland, Ejstrup (Biowide 031), 9.vi.2016, reared from gall on Carex nigra var. recta, H. H. Bruun leg., specimen after DNA extraction, prepared on slide, No. PLA 10 (coll. JSL-UOC).
 Diagnosis. This species can be recognized by the short, apically blunt gonostylus, only about half as long as gonocoxite, hypoproct subrectangular and posteriorly straight, aedeagus broad and apically rounded, reaching to two thirds of gonocoxite, and gonocoxites relatively broad (Figs 5A,B). It belongs to the group with 12 flagellomeres, narrow eye bridge, and mostly light orange-brown coloration, without distinct dark markings.
 Discussion. This species is represented in our material only by specimens from Denmark. It is interesting that we have not found it yet in the Czech Republic or Slovakia. It appears as not restricted to a single species of Carex. In the original description by RȖBsAAMEN (1899b), three different Carex species are mentioned as hosts, i.e. Carex stricta (= C. elata), C. gracilis (= C. acuta), C. goodenoughii (= C. nigra). All these three Carex species are rather closely related, several of them forming hybrids. They are all part of the large Carex sect. Phacocystis, and even a smaller and tighter group within it. It is thus possible that Planetella gallarum may be specific to this group of carices.

Understanding the decision-making from a cognitive and metacognitive perspective: A theoretical framework

Publisher: name: Zenodo
Year: 2023

description: Human decision-making depends on a complex system and several factors (interests, environment, motivation, emotions, etc.). This research examines human decision-making from a perspective outside the financial determinants that interfere with the decision. In fact, several factors are involved in decision making, both internal and external. In order to show the impact of these factors, using the documentary research method, we distinguish between cognitive and metacognitive factors. The findings of the literature review highlight the existence of certain cognitive factors, such as heuristics that are described as shortcuts, which can bias information and lead to errors of judgement. Apart from the mental processes which handle and analyse information in order to make a decision, we also notice that external factors are taken into account which are outside the scope of cognition, such as culture as a meta-cognitive factor.
Quantum vacuum radiation in optical glass

description: A recent experimental claim of the detection of analogue Hawking radiation in an optical system [PRL 105 (2010) 203901] has led to some controversy [PRL 107 (2011) 149401, 149402]. While this experiment strongly suggests some form of particle creation from the quantum vacuum (and hence it is per se very interesting), it is also true that it seems difficult to completely explain all features of the observations by adopting the perspective of a Hawking-like mechanism for the radiation. For instance, the observed photons are emitted parallel to the optical horizon, and the relevant optical horizon is itself defined in an unusual manner by combining group and phase velocities. This raises the question: Is this really Hawking radiation, or some other form of quantum vacuum radiation? Naive estimates of the amount of quantum vacuum radiation generated due to the rapidly changing refractive index --- sometimes called the dynamical Casimir effect --- are not encouraging. However we feel that naive estimates could be misleading depending on the quantitative magnitude of two specific physical effects: "pulse steepening" and "pulse cresting". Plausible bounds on the maximum size of these two effects results in estimates much closer to the experimental observations, and we argue that the dynamical Casimir effect is now worth additional investigation.
