Surfing on the Edge: Chaos vs. Near-Integrability in the System of Jovian Planets

description: We demonstrate that the system of Jovian planets (Sun+Jupiter+Saturn+Uranus+Neptune), integrated for 200 million years as an isolated 5-body system using many sets of initial conditions all within the uncertainty bounds of their currently known positions, can display both chaos and near-integrability. The conclusion is consistent across four different integrators, including several comparisons against integrations utilizing quadruple precision. We demonstrate that the Wisdom-Holman symplectic map using simple symplectic correctors as implemented in Mercury 6.2 (Chambers 1999) gives a reliable characterization of the existence of chaos for a particular initial condition only with timesteps less than about 10 days, corresponding to about 400 steps per orbit. We also integrate the canonical DE405 initial condition out to 5 Gy, and show that it has a Lyapunov Time of 200--400 My, opening the remote possibility of accurate prediction of the Jovian planetary positions for 5 Gy.

Evaluating The Implementation Of Wastewater-Based Surveillance For COVID-19 In Kisumu, Kenya

description: The World Health Organization (WHO) has recommended various COVID-19 surveillance tools, including wastewater-based surveillance (WBS), which has demonstrated promising results in high-income countries (HICs). However, its application in low- and middle-income countries (LMICs) remains limited. This study explores WBS's potential as a complementary surveillance tool in a resource-constrained environment, Kisumu, Kenya, where sewer infrastructure is inadequate.
Conducted from March 2022 to March 2023by University of Illinois Chicago (UIC) researchers and the Kenyan non-profit Safe Water and AIDS Project, the research involved sporadic sampling of wastewater from centralized and decentralized sites, yielding 161 samples with 23 positive for SARS-CoV-2 and epidemiological data from 4 major hospitals in Kisumu. Time series analysis shows that by combining centralized and decentralized samples wastewater surveillance has the capacity to predict an upcoming wave 6 to 11 days prior to a positive case report. Additionally, wastewater testing in Kisumu has detected SARS-CoV-2, highlighting a chance to enhance COVID-19 surveillance among high-risk groups in resource limited settings.
The study also addresses the barriers to utilizing WBS data for decision-making in Kisumu. Key barriers identified include the absence of a policy framework for use of WBS, financial limitations, and insufficient awareness among stakeholders. In-depth interviews with 14 stakeholders were conducted. Participants noted that although WBS has potential to support public health, it was rarely used in public health decisions in Kisumu due to above challenges. To address these challenges, we recommend establishing a comprehensive network that includes a broader range of stakeholders. This collaborative approach is crucial for successfully implementing WBS for COVID-19 in any setting.

Effective health communication requires understanding the demographics, COVID-19 knowledge, attitudes, and information preferences of informal settlement residents compared to those in formal communities. We conducted intercept interviews at public toilets near informal settlements to evaluate these factors. Analysis of data from 752 study participants shows that informal settlement residents perceive a higher risk of contracting COVID-19 and struggle more with accessing and understanding related health information. These insights suggest the need for tailored health communication strategies to better address the specific needs of informal settlement residents.

description: Brownian Dynamics algorithms are widely used for simulating soft-matter and biochemical systems. In recent times, their application has been extended to the simulation of coarse-grained models of cellular networks in simple organisms. In these models, components move by diffusion, and can react with one another upon contact. However, when reactions are incorporated into a Brownian Dynamics algorithm, attention must be paid to avoid violations of the detailed-balance rule, and therefore introducing systematic errors in the simulation. We present a Brownian Dynamics algorithm for reaction-diffusion systems that rigorously obeys detailed balance for equilibrium reactions. By comparing the simulation results to exact analytical results for a bimolecular reaction, we show that the algorithm correctly reproduces both equilibrium and dynamical quantities. We apply our scheme to a ``push-pull'' network in which two antagonistic enzymes covalently modify a substrate. Our results highlight that the diffusive behaviour of the reacting species can reduce the gain of the response curve of this network.

description: Highly oriented polymer films can show considerable anisotropy in the thermoelectric properties leading to power factors beyond those predicted by the widely obeyed power law linking the thermopower $S$ and the electrical conductivity $σ$ as $S\proptoσ^{-1/4}$. This has led to encouraging practical results with respect to the electrical conductivity, notwithstanding that the conditions necessary to enhance $σ$ and $S$ simultaneously are less clear. Here, kinetic Monte Carlo simulations are used to study the impact of structural anisotropy on the thermoelectric properties of disordered organic semiconductors. We find that stretching is a suitable strategy to improve the conductivity along the direction of strain, while the effect on the power factor depends on the morphology the polymer crystallizes. In general, crystalline polymers show a simultaneous increase in $σ$ and $S$ which is not the case for amorphous polymers. Moreover, we show that the trends resulting from simulations based on variable-range hopping are in good agreement with experiments and can describe the different functional dependencies in the $S$ versus $σ$ behaviour of different directions.

description: We discover several magnetic Feshbach resonances in collisions of ultracold K(39) atoms, by studying atom losses and molecule formation. Accurate determination of the magnetic-field resonance locations allows us to optimize a quantum collision model for potassium isotopes. We employ the model to predict the magnetic-field dependence of scattering lengths and of near-threshold molecular levels. Our findings will be useful to plan future experiments on ultracold potassium atoms and molecules.

description: We present the serendipitous discovery of a young stellar cluster in the Galactic disk at l=12deg. Using Keck/NIRSPEC, we obtained high- and low-resolution spectroscopy of several stars in the cluster, and we identified one red supergiant and two blue supergiants. The radial velocity of the red supergiant provides a kinematic cluster distance of 4.7pm0.4 kpc, implying luminosities of the stars consistent with their spectral types. Together with the known Wolf-Rayet star located 2.4' from the cluster center, the presence of the red supergiant and the blue supergiants suggests a cluster age of 6-8 Myr, and an initial mass of 2000 Msun. Several stars in the cluster are coincident with X-ray sources, including the blue supergiants and the Wolf-Rayet star. This is indicative of a high binary fraction, and is reminiscent of the massive young cluster Westerlund 1. The cluster is coincident with two supernova remnants, SNR G12.72-0.0 and G12.82-0.02, and the highly magnetized pulsar associated with the TeV gamma-ray source HESS J1813-178. The mixture of spectral types suggests that the progenitors of these objects had initial masses of 20 - 30 Msun.

description: A set of multi-room compartment fire experiments were conducted to obtain measurements of hot gas layer temperature and depth. These measurements were used as an input to an inverse fire model that coupled a genetic algorithm with a zone fire model to calculate a unique solution to the original fire size and door opening used in the experiments. The objective of this research was to calculate simultaneously the real-time fire size and fire door opening of the experiment using a combination of hot gas layer temperature and hot gas layer height measurements from a multi-room compartment in concert with an inverse fire model. This research focused on increasing the robustness of an inverse fire model (IFM) with respect to physical accuracy and multi-variable calculations. The IFM successfully identified a unique solution and calculated fire size within 10-40% of experimental values.

description: The magneto-rotational instability (MRI) is the most likely mechanism for transportation of angular momentum and dissipation of energy within hot, ionized accretion discs. This instability is produced through the interactions of a differentially rotating plasma with an embedded magnetic field. Like all substances in nature, the plasma in an accretion disc has the potential to become magnetically polarized when it interacts with the magnetic field. In this paper, we study the effect of this magnetic susceptibility, parameterized by $χ_m$, on the MRI, specifically within the context of black hole accretion. We find from a linear analysis within the Newtonian limit that the minimum wavelength of the first unstable mode and the wavelength of the fastest growing mode are shorter in paramagnetic ($χ_m>0$) than in diamagnetic ($χ_m<0$) discs, all other parameters being equal. Furthermore, the magnetization parameter (ratio of gas to magnetic pressure) in the saturated state should be smaller when the magnetic susceptibility is positive than when it is negative. We confirm this latter prediction through a set of numerical simulations of magnetically polarized black hole accretion discs. We additionally find that the vertically integrated stress and mass accretion rate are somewhat larger when the disc is paramagnetic than when it is diamagnetic. If astrophysical discs are able to become magnetically polarized to any significant degree, then our results would be relevant to properly interpreting observations.

description: We study the long wavelength shear modes (Tkachenko waves) of triangular lattices of singly quantized vortices in neutron star interiors taking into account the mutual friction between the superfluid and the normal fluid and the shear viscosity of the normal fluid. The set of Tkachenko modes that propagate in the plane orthogonal to the spin vector are weakly damped if the coupling between the superfluid and normal fluid is small. In strong coupling, their oscillation frequencies are lower and are undamped for small and moderate shear viscosities. The periods of these modes are consistent with the observed ~100-1000 day variations in spin of PSR 1828-11.

description: We study theoretically optomechanical interactions in a semiconductor microcavity with embedded quantum well under the optical pumping by a Bessel beam, carrying a non-zero orbital momentum. Due to the transfer of orbital momentum from light to phonons, the microcavity can act as an acoustic circulator: it rotates the propagation direction of the incident phonon by a certain angle clockwise or anticlockwise. Due to the optomechanical heating and cooling effects, the circulator can also function as an acoustic laser emitting sound with nonzero angular momentum. Our calculations demonstrate the potential of semiconductor microcavities for compact integrable optomechanical devices.

description: Non-platonic relationships are a significant stressor for women in college, and can lead to a variety of negative outcomes (Lindgren, Parkhill, George and Hendershot, 2008).  Flirting is how non-platonic interactions begin, yet it has not been studied in a university setting.  In this study, semi-structured interviews with twelve heterosexual female college students gathered information about women's intentions, behaviors, and outcomes in non-platonic heterosexual interactions.  Understanding college students' goals and communication strategies in non-platonic interactions may improve educational and intervention strategies (Lindgren, Blayney, Schacht, George & Pantalone, 2009).  Researchers analyzed interview data using Consensual Qualitative Research methods, which allow for rigorous exploratory analysis aimed at describing the actual experiences of college student women. Students spoke about their personal experiences as well as to their perceptions of norms on college campuses. The conclusions drawn from the data demonstrate the ways in which the college social environment, indirect interpersonal communication, and a desire for human connection characterize college student women's experiences of non-platonic relationships in college.

description: Prompted by a recent paper by Dima and Schad, we re-consider the problem of inferring magnetic properties of the corona using polarimetric observations of magnetic dipole (M1) lines. Dima and Schad point to a potential source of degeneracy in a formalism developed by Plowman, which under some circumstances can lead to the solution being under-determined. Here we clarify the nature of the problem. Its resolution lies in solving for the scattering geometry using the elongation of the observed region of the corona. We discuss some conceptual problems that arise when casting the problem for inversion in the observer's reference frame, and satisfactorily resolve difficulties identified by Plowman, Dima and Schad.

description: Real-time access to accurate and reliable timing information is necessary to profile scientific applications, and crucial as simulations become increasingly complex, adaptive, and large-scale. The Cactus Framework provides flexible and extensible capabilities for timing information through a well designed infrastructure and timing API. Applications built with Cactus automatically gain access to built-in timers, such as gettimeofday and getrusage, system-specific hardware clocks, and high-level interfaces such as PAPI. We describe the Cactus timer interface, its motivation, and its implementation. We then demonstrate how this timing information can be used by an example scientific application to profile itself, and to dynamically adapt itself to a changing environment at run time.

description: East African ecosystems have been shaped by long-term socio-ecological-environmental interactions. Although much previous work on human-environment interrelationships have emphasised the negative impacts of human interventions, a growing body of work shows that there have also often been strong beneficial connections between people and ecosystems, especially in savanna environments. However, limited information and understanding of past interactions between humans and ecosystems of periods longer than a century hampers effective management of contemporary environments. Here, we present a late Holocene study of pollen, fern spore, fungal spore, and charcoal analyses from radiocarbon-dated sediment sequences and assess this record against archaeological and historical data to describe socio-ecological changes on the Laikipia Plateau in Rift Valley Province, Kenya. The results suggest a landscape characterised by closed forests between 2268 years before present (cal year BP) and 1615 cal year BP when there was a significant change to a more open woodland/grassland mosaic that continues to prevail across the study area. Increased amounts of charcoal in the sediment are observed for this same period, becoming particularly common from around 900 cal year BP associated with fungal spores commonly linked to the presence of herbivores. It is likely these trends reflect changes in land use management as pastoral populations improved and extended pasture, using fire to eradicate disease-prone habitats. Implications for contemporary land use management are discussed in the light of these findings.

description: Ausgehend von der Analyse werrasulfatischer Sedimentgefüge am Osthang der zechsteinzeitlich wirksamen Eichsfeld-Schwelle und ihrem Vergleich mit bekannten Gefügetypen von Beckensulfaten, kann die Entstehung des Sulfatwalles der
Eichsfeld-Schwelle und anderer Sulfatwälle des Zechsteinbeckens erklärt und damit ein Beitrag zur paläotektonischen Entwicklung der Mitteleuropäischen Zechsteinsenke geleistet werden.
Morphologische Vorbedingungen führen zur Ausbildung unterschiedlicher Lösungstiefen und verursachen dadurch unterschiedlich wirksame Eindunstung. Diese bedingt verstärkten Lösungsnachstrom und damit erhöhte Stoffzufuhr zu den Schwellengebieten. Es entsteht ein starkes Konzentrationsgefälle, das über den Untiefen intensive Sulfatabscheidung, in den Beckenräumen jedoch wegen dort nur allmählich zunehmender Lösungskonzentration die Bildung von geringmächtigen Sulfatlaminiten hervorruft. Bei sich angleichender Lösungskonzentration gelangen Flaseranhydrite, zugleich auf die Schwellenhänge übergreifend, zur Ablagerung. Mehrfach sich wiederholende Lösungeverdünnungen und nachfolgende Konzentrationen erzeugen rhythmisch sich wiederholende Konzentrationsgefälle mit stark unterschiedlichen Sedimentationsraten über Schwellen- und Beckenregionen. Am Schwellenhang bildet sich allmählich eine Sedimentationsterrasse. Längere Perioden anhaltender Lösungsverdünnung bedingen stabile Konzentrations- und Mächtigkeitsungleichgewichte. Sedimentumlagerungen sind die Folge. Die Resedimentation erfaßt zunächst das Lockermaterial der Schwellen. Es entstehen Sulfatturbidite, die auf Grund des Transportmechanismus von Trübeströmen auch über die Schwellenhänge hinaus in benachbarte Beckenräume getragen werden (distale Turbidite) und dort eine Mächtigkeitsaufblähung der Laminite verursachen. Bei extremen Mächtigkeitsungleichgewichten geht die turbiditische Resedimentation in die Umlagerung teilverfestigter und verfestigter Materialien über. Es entstehen Sulfat-Olisthostrome

description: The entropy bound conjecture concerning black hole dynamical horizons is proved. The conjecture states, if a dynamical horizon, $D_H$, is bounded by two surfaces with areas of $A_B$ and $\abp$ ($\abp>A_B$), then the entropy, $S_D$, that crosses $D_H$ must satisfy $S_D\leq {1/4}(\abp-A_B)$. We show that this conjecture is implied by the generalized Bousso bound. Consequently, the generalized second law holds for dynamical horizons. Finally, we show that the lightlike bousso bound and its spacelike counterpart can be unified as one bound.

description: The permanent rotation of the N.E.Pacific Rift is divided into three first-order rotations covering the whole rift between 20° and 60° N. during the last 80 mio years. The general movement of a clockwise rotation (35-40° altogether) was interrupted during the time between 40 and 20 m.y.b.p. by a weak counterclockwise one (8° altogether). These superordinate rotations can be subdivided in smaller ones with an average duration of 10 m.y. only. It is to suppose that all these rotations are a readjustment of the rift to a changed position of the spreading pole. Compared to it, short-time, oscillatory rotations represent compensating movements of the rift and stabilizing efforts of the plate. For the S.E.Pacific Rift it is supposed that the. Counterclockwise rotation taking place there for the last 7 m.y. is continuing, as may be concluded from the distribution of earthquake epicentres.
Furthermore, the problems of pendulum movements and hinge zones at the S.E. and N.E.Pacific Rifts are discussed, which represent the magmatic activity of the rift. Hinge zones are lines of weakness of rifts, which can become fault zones. Up to now they were not mentioned in literature.
The internal deformations of the Pacific Plate and Juan de Fuca Plate off California indicated by kinks of the rift, fault-folding and strike slip faults became intense about 1-2 m.y.b.p.

Theatre couple

description: The present study is the first treatment of the careers of two professional actors as a couple in early modern Italy. It examines the success achieved by Giovan Battista Andreini (1576-1654) and his wife Virginia Ramponi (1583-ca.1631) as a result of the self-representation and marketing strategies they devised and adopted. Their careers are considered as a unicum; two faces of a single product to be sold on the market: the professional theatre couple. This thesis presents a pair of mirrored images: it looks at specific moments of the careers of Andreini and Ramponi from both his perspective and hers, in order to define their individual contributions to the success they enjoyed together and to show that their achievements were the result of a synergy. Against the historical background of post-Tridentine Italy, this study illustrates their literary, performative, iconographic and epistolary tactics as both a reaction to the opposition to professional performers led by Counter-Reformation clergy and a response to the promotion of professional performers led by academicians. By exploring Andreini and Ramponi’s engagement with Counter-Reformation thought, their relation with cultural and political institutions, their power and artistic networks, this study offers a new perspective on the historical and cultural context of early modern Italy. In revealing the leading role of Ramponi in the company of which the Andreinis were part, and the impact of her international prestige in the reception of professional performers, it aims to enrich the scholarly discourse on the agency of women in early modern Italy. By looking at the career of the comici as a couple, it writes a new chapter in the social history of early modern theatre which opens up new avenues of research on professional theatre.

description: We present mid-infrared data of a sample of 57 AGNs obtained with the instrument ISOCAM on board the satellite ISO. The images were obtained through the LW2 (6.75 microns) and LW7 (9.62 microns) filters. This is a new analysis of Clavel et al. (2000) galaxy sample, which is divided into 26 type 1 (< or = 1.5) and 28 type 2 (> 1.5) Seyfert galaxies, plus three QSOs. The spatial resolution of the images allow us to separate the nuclear and the extended contributions to the total emission after decomposing the brightness profiles into different morphological components. The most common components are a central point source (identified as the active nucleus) and an exponential disk. In some cases a bulge, a bar or a ring are needed. The relative contribution of the nucleus to the total emission appears larger in Seyfert 1 than in Seyfert 2. This result confirms that both types of Seyfert galaxies are different in the mid-infrared and supports the existence of an structure which produces anisotropic emission in this wavelength range. We have also explored correlations between the mid-infrared and the radio and X-ray wavelength ranges. The well established radio/infrared correlation is mantained in our sample for the global emission of the galaxies. If only the nuclear infrared emission is considered then a non-linear correlation is apparent in the luminosity-luminosity scatter diagram. The ratio between the intrinsic hard X-ray and the nuclear mid-infrared emission presents large scatter and slightly larger values for type 2 Seyfert galaxies. These results seem to be consistent with the presence of a clumpy dusty torus surrounding the active nucleus.

description: We drive a quantum kinetic equation under discrete impurities for the Wigner function from the quantum Liouville equation. To attain this goal, the electrostatic Coulomb potential is separated into the long- and short-range parts, and the self-consistent coupling with Poisson's equation is explicitly taken into account. It is shown that the collision integral associated with impurity scattering as well as the usual drift term is derived on an equal footing and that the conventional treatment of impurity scattering under the Wigner function scheme is inconsistent in the sense that the collision integral is introduced in an ad hoc way and, thus, the short-range part of the impurity potential is double-counted. The Boltzmann transport equation (BTE) is derived without imposing an assumption of random impurity configurations over the substrate. The derived BTE is able to describe the discrete nature of impurities such as potential fluctuations and, thus, appropriate to analyze electron transport under semiconductor nanostructures.

The effects of this quenched randomness on population densities, transient oscillations, spatial correlations, and invasion fronts are investigated. We find that spatial variability in the predation rate results in more localized activity patches, which in turn causes a remarkable increase in the asymptotic population densities of both predators and prey, and accelerated front propagation.

description: INTRODUCTION: Combination vaccines containing whole-cell pertussis antigens were phased out from the Australian national immunisation programme between 1997 and 1999 and replaced by the less reactogenic acellular pertussis (aP) antigens. In a large case-control study of Australian children born during the transition period, those with allergist diagnosed IgE-mediated food allergy were less likely to have received whole-cell vaccine in early infancy than matched population controls (OR: 0.77 (95% CI, 0.62 to 0.95)). We hypothesise that a single dose of whole-cell vaccine in early infancy is protective against IgE-mediated food allergy. METHODS AND ANALYSIS: This adaptive double-blind randomised controlled trial is investigating whether a mixed whole-cell/aP vaccine schedule prevents allergic disease in the first year of life. The primary outcome is IgE-mediated food allergy by 12 months of age.

description: The Muscovy duck is a poultry for its cost-effective breeding and significant economic importance. It has undergone a systematic process of artificial domestication and natural selection, resulting in the emergence of distinct characteristics among different lines of Muscovy duck. Our comparative genomic analysis, encompassing ROH, HBD, and selective sweep in the Crimo and Fujian populations, provides valuable insights for the breeding of Muscovy ducks in the Fujian population. This study contributes to the understanding of the genetic basis among different Muscovy duck lines, providing knowledge for their breeding and genetic improvement.

description: The tracking of symmetry-breaking events in space is a longlasting goal of astrochemists, aiming at an understanding of homochiral Earth chemistry. One current effort at this frontier aims at the detection of small chiral molecules in the interstellar medium. For that, high-resolution laboratory spectroscopy data is required, providing blueprints for the search and assignment of these molecules using radioastronomy. Here, we used chirped-pulse Fourier transform microwave and millimeter-wave spectroscopy and frequency modulation absorption spectroscopy to record and assign the rotational spectrum of the chiral aromatic molecule styrene oxide, $\mathrm{C_{6}H_{5}C_{2}H_{3}O}$, a relevant candidate for future radioastronomy searches. Using experimental data from the 2-12, 75-110, 170-220, and 260-330 GHz regions, we performed a global spectral analysis, complemented by quantum chemistry calculations. A global fit of the ground state rotational spectrum was obtained, including rotational transitions from all four frequency regions. Primary rotational constants as well as quartic and sextic centrifugal distortion constants were determined. We also investigated vibrationally excited states of styrene oxide, and for the three lowest vibrational states, we determined rotational constants including centrifugal distortion corrections up to the sextic order. In addition, spectroscopic parameters for the singly-substituted $^{13}$C and $^{18}$O isotopologues were retrieved from the spectrum in natural abundance and used to determine the effective ground state structure of styrene oxide in the gas phase. The spectroscopic parameters and line lists of rotational transitions obtained here will assist future astrochemical studies of this class of chiral organic molecules.

description: The thermochemical structure of lithospheric and asthenospheric mantle exert primary controls on surface topography and volcanic activity. Volcanic rock compositions and mantle seismic velocities provide indirect observations of this structure. Here, we compile and analyze a global database of the distribution and composition of Neogene-Quaternary intraplate volcanic rocks. By integrating this database with seismic tomographic models, we show that intraplate volcanism is concentrated in regions characterized by slow upper mantle shear-wave velocities and by thin lithosphere (i.e. <100 km). We observe a negative correlation between shear-wave velocities at depths of 125-175 km and melt fractions inferred from volcanic rock compositions. Furthermore, mantle temperature and lithospheric thickness estimates obtained by geochemical modeling broadly agree with values determined from tomographic models that have been converted into temperature. Intraplate volcanism often occurs in regions where uplifted (but undeformed) marine sedimentary rocks are exposed. Regional elevation of these rocks can be generated by a combination of hotter asthenosphere and lithospheric thinning. Therefore, the distribution and composition of intraplate volcanic rocks through geologic time will help to probe past mantle conditions and surface processes.

description: In den oberen Schichten der Erde bis herab zur Tiefe D werden räumliche Dichteanomalien verteilt, und an der Erdoberfläche wird eine Flächenbelegung angenommen. Diese werden so bestimmt, daß das Integral über ihre Quadrate zu einem Minimum wird. Ferner sollen ihre gravimetrischen Wirkungen zusammen mit denen der Gebirgsmassen und deren isostatischer Kompensation im Außenraum das aus Satelliten bestimmte Potentialfeld ergeben und in Tiefen größer als D zu keiner Änderung des Potentials führen. Durch Integration der Differentialgleichungen des elastischen Gleichgewichts ergeben sich aus den Dichteanomalien die elastische Deformation und aus·ihr der Spannungstensor und die Spannungsunterschiede.

description: Das Ziel der vorliegenden Arbeit ist die Untersuchung der photoelektrischen Registrierung von Sterndurchgangszeiten, um einen Beitrag zur Entwicklung des photoelektrischen Zenitrohrs (PEZR) zu leisten.
Nach Hinweisen zur Zielstellung werden zunächst in einem Überblick verschiedene bisher angewendete photoelektrische Meßverfahren vorgestellt und dann das ausgewählte Meßverfahren sowie die Entwicklung der Versuchsapparatur beschrieben. Daneben wird das Auswerteverfahren der registrierten Meßwerte mit einer EDVA zur Ermittlung der Sterndurchgangszeit vorgelegt. Anschließend werden die Reichweite und die Genauigkeit der entwickelten Versuchsapparatur abgeschätzt. Weiter werden die Ergebnisse sowie die Erfahrungen aus der Erprobung in 5 Beobachtungsserien mit 5 verschiedenen Gittern und 870 Sterndurchgangsbeobachtungen dargestellt. (Bei einem Objektiv mit der effektiven Öffnung von 16,7 cm und der Brennweite von 100 cm waren die Sterne bis zur Größenklasse 10 zu beobachten, und es wurden durchschnittliche Meßfehler in 2 Koordinaten von 0,082" erreicht.) Zum Schluß erfolgen die Einschätzung und die Diskussion von Verbesserungsmöglichkeiten für den endgültigen Einsatz am PEZR.

description: In peripheral collisions of relativistic heavy ions highly excited spectators containing Lambda-hyperons can be produced. Such strange spectator matter may undergo a break-up into many fragments (multifragmentation) as it is well established for ordinary nuclear systems. We generalize the statistical multifragmentation model, previously successfully used for the description of experimental data, for the case of hypernuclear systems. We predict relative yields of hypernuclei and the main characteristics of such a break-up. We point at a connection of this phenomenon with a liquid-gas phase transition in hypermatter.

description: We study heat transport in quantum spin systems analytically and numerically. First, we demonstrate that heat current through a two-level quantum spin system can be modulated from zero to a finite value by tuning a magnetic field. Second, we show that a spin system, consisting of two dissimilar parts - one is gapped and the other is gapless, exhibits current rectification and negative differential thermal resistance. Possible experimental realizations by using molecular junctions or magnetic materials are discussed.

description: The correct treatment of d electrons is of prime importance in order to predict the electronic properties of the prototype chalcopyrite semiconductors. The effect of d states is linked with the anion displacement parameter u, which in turn influences the bandgap of these systems. Semilocal exchange-correlation functionals which yield good structural properties of semiconductors and insulators often fail to predict reasonable u because of the underestimation of the bandgaps arising from the strong interplay between d electrons. In the present study, we show that the meta-generalized gradient approximation (meta-GGA) obtained from the cuspless hydrogen density (MGGAC) [Phys. Rev. B 100, 155140 (2019)] performs in an improved manner in apprehending the key features of the electronic properties of chalcopyrites, and its bandgaps are comparative to that obtained using state-of-art hybrid methods. Moreover, the present assessment also shows the importance of the Pauli kinetic energy enhancement factor, $α=(τ-τ^W)/τ^{unif}$ in describing the d electrons in chalcopyrites. The present study strongly suggests that the MGGAC functional within semilocal approximations can be a better and preferred choice to study the chalcopyrites and other solid-state systems due to its superior performance and significantly low computational cost.
