description: High-spin states in the doubly-odd $^{198}$Bi nucleus have been studied by using the $^{185,187}$Re($^{16}$O, xn) reactions at the beam energy of 112.5 MeV. $γ-γ$ coincidence were measured by using the INGA array with 15 Compton suppressed clover HPGe detectors. The observed levels have been assigned definite spin-parity. The high spin structure is grouped into three bands (B1, B2 and B3), of which two (B1 and B2) exhibit the properties of magnetic rotation (MR). Tilted axis cranking calculations were carried out to explain the MR bands having large multi-quasiparticle configurations. The calculated results explain the bands B1 and B2 very nicely, confirming the shears mechanism and suggest a crossing of two MR bands in both the cases. The crossing is from 6-qp to 8-qp in band B1 and from 4-qp to 6-qp in band B2, a very rare finding. A semiclassical model has also been used to obtain the particle-hole interaction strengths for the bands B1 and B2, below the band crossing.

description: Breast cancer (BC) is a disease of aging and the number of older BC patients in the U.S. is rising. Immunohistochemical data show that with increasing age, the incidence of hormone receptor-positive tumors increases, whereas the incidence of triple-negative tumors decreases. Few data exist on the frequency of molecular subtypes in older women. Here, we characterize the incidence and outcomes of BC patients by molecular subtypes and age.

description: Moduli fields with Planck-suppressed couplings to light species are common in string compactifications. Decays of these moduli can reheat the universe at a late time and produce dark matter non-thermally. For generic moduli fields motivated by string theory with masses similar to that of the gravitino and TeV-scale superpartners in the minimal supersymmetric Standard Model (MSSM), the non-thermal production of the lightest superpartner (LSP) tends to create an unacceptably large relic density or too strong of an indirect detection signal. We call this the moduli-induced LSP problem of the MSSM. In this paper we investigate extensions of the MSSM containing new LSP candidates that can alleviate this tension. We examine the viability of this scenario in models with light Abelian and non-Abelian hidden sectors, and symmetric or asymmetric dark matter. In these extensions it is possible, though somewhat challenging, to avoid a moduli-induced LSP problem. In all but the asymmetric scenario, the LSP can account for only a small fraction of the observed dark matter density.

Forecasting Detectability of Protoplanets embedded in Disks using hydrodynamic simulations

Publisher: name: Zenodo
Year: 2018

description: We present an observability model that can be used to predict expected magnitudes for young planets embedded in transition disks, still affected by extinction due to material in the disk. We focus on Jupiter-size planets at a late stage of their formation when the planet has carved a deep gap in the gas and dust distribution and the disk could be transparent to the planet flux at certain wavelengths. The expected magnitude at typically observed bands in the IR is estimated by means of three-dimensional hydrodynamical models, performed for several planet masses. Observed fluxes are obtained by combining these models to giant planet evolutionary models for typical extinction properties of the material. We find the detectability of the embedded planets with masses approximately 1-2Mjup to be strongly dependent on the assumed disc masses and on the wavelength considered. For most cases these planets would be hard to observe at the J-, H- and K-bands. On the other hand planets of masses approaching 5Mjup are always detectable. We derive observability curves that we then apply to the transition disks around CQ Tau and TW Hya

description: A critical role of the transportation infrastructure in agricultural productivity has been widely recognized. Despite the widespread recognition and acceptance that such a relationship exists, empirical studies testing this hypothesis in the agricultural sector is rare both in Korea and abroad. With a focus on the transportation accessibility conditions among regions, this study intends to examine the effect of transportation infrastructure on agricultural productivity. Using panel data on 152 local autonomies throughout 2010-2016, the study employs spatial panel models that best fit our data’s spatial structure. The key findings of the study are that while both road and railway accessibility indices are negatively associated with agricultural productivity, the increase in railway accessibility in modal regions is closely related to the efficiency gains of neighboring areas concerning agricultural productivity. Presenting the problems of the negative relationship between transportation SOC and agricultural productivity, this study concludes with some policy implications and discusses limitations in research for future directions for related studies.

description: The cohesive collective motion (flocking, swarming) of autonomous agents is ubiquitously observed and exploited in both natural and man-made settings, thus, minimal models for its description are essential. In a model with continuous space and time we find that if two particles arrive symmetrically in a plane at a large angle, then (i) radial repulsion and (ii) linear self-propelling toward a fixed preferred speed are sufficient for them to depart at a smaller angle. For this local gain of momentum explicit velocity alignment is not necessary, nor are adhesion/attraction, inelasticity or anisotropy of the particles, or nonlinear drag. With many particles obeying these microscopic rules of motion we find that their spatial confinement to a square with periodic boundaries (which is an indirect form of attraction) leads to stable macroscopic ordering. After varying the density of particles at constant system size and varying the size of the system with constant particle density we predict that in the infinite system size (or density) limit the hysteresis loop disappears and the transition becomes continuous. We note that animals, humans, drones, etc. tend to move asynchronously and are often more responsive to motion than positions. Thus, for them velocity-based continuous models can provide higher precision than coordinate-based models. An additional characteristic and realistic feature of the model is that convergence to the ordered state is fastest at a finite density, which is in contrast to models applying (discontinuous) explicit velocity alignments and discretized time. In summary, we find that the investigated model can provide a minimal description of flocking.

The Vertical Structure of Inner Disks - Gray, Red, and Gas extinction
Creators: name: Schneider, P. Christian
Publisher: name: Zenodo
Year: 2018

description: The periodic occulations of the central star in AA Tau-like objects provides an excellent opportunity to study the vertical structure of the inner disk. We present a series of flux-calibrated Xshooter spectra covering the full variability range from the brightest to the dim state. The flux evolution requires two components, red and gray absorption with variable contributions. Combined with the rotation period, this gives the vertical heights of the two extinction components. We also measure the an increase in gas absorption lines during dimmer phases. However, the increase in gas column density falls short of expectations based on ISM ratios, which points to an absorber with a low gas content.
A Closer Look at the Inner Disks of Herbig Ae Stars HD 163296 and HD 190073

description: We combine multi-epoch, H- and K-band observations from the VLTI and the CHARA interferometers to present the most complete published sample of high angular resolution measurements of the Herbig Ae Stars HD 163296 and HD 190073. We confirm previous results suggesting that significant near-infrared emission originates from within the supposed dust destruction radius of this class of object, and further characterize the emission profile. In particular, we find that the inner-disk brightness profile for both objects is remarkably Gaussian-like, with little to no sign of a sharp edge expected from a sublimation front. Moreover, the observed H- and K-band sizes of these disks are the same within (3±3) % for HD 163296 and (6±10) % for HD 190073. We use these results to explore potential mechanisms for the observed inner emission and find evidence that the observed spectral types of these heavy accretors are biased towards higher temperatures due to emission from the accretion shock/boundary layer.

Dust concentration and emission in protoplanetary disks vortices
Creators: name: Sierra Morales, Anibal Estuardo
Publisher: name: Zenodo
Year: 2018

description: We study the dust concentration and emission in protoplanetary disks vortices. We extend the Lyra-Lin solution for the dust concentration of a single grain size to a power-law distribution of grain sizes. Assuming dust conservation in the disk, we find an analytic dust surface density as a function of the grain radius. We calculate the increase of the dust-to-gas mass ratio and the slope of the dust size distribution due to grain segregation within the vortex. We apply this model to a numerical simulation of a disk containing a persistent vortex and we find the disk emission at millimeter wavelengths corresponding to synthetic observations with ALMA and VLA. The simulated maps at 7mm and 1cm show a strong azimuthal asymmetry due to the disks becomes optically thin while the vortex remains optically thick. The large vortex opacity is mainly due to an increase in the dust-to-gas mass ratio, however, the change in the slope of the dust size distribution also increases the opacity by a factor of two.

Our main result asserts that such a system exists under the assumption of the uniform mass distribution on an interval at the starting moment. We introduce a stochastic integral with respect to such a flow and obtain the total local time as the density of the occupation measure for all particles.

Space and ground-based study of star-disc interaction processes in classical T Tauri-type stars
Creators: name: Siwak, Michal
Publisher: name: Zenodo
Year: 2018

description: Over the last decade, the MOST satellite provided a handful of high-precision light curves of pre-main sequence stars. TW Hya - the closest CTTS to us and accreting disc plasma with a moderate rate of 1e-9 solar mass per year - was observed seven times. It always showed slightly different light variations, either more or less irregular, what may be interpreted that accretion can switch between an unstable and a moderately stable regime. Interestingly, RU Lup having one of the highest known accretion rates (1e-8) always showed irregular behavior typical for unstable accretion, while slowly accreting (1e-11) IM Lup showed regular light variations both in space-based and in long-term ASAS data, what is typical for stable accretion regime. All the above appears to be in agreement with the numerical picture successively developed by Dr. M. Romanova group. Their models predict also waves induced in the disc plasma structure due to interactions with a rotating tilted magnetosphere of a star. In particular, the solution for CTTS with enhanced accretion is one of several possibilities that can be used for interpretation of quasi-periodic light variations arising in the inner disc of FU Ori.

description: After decreasing for nearly a decade, hunger is once again on the rise. The major drivers behind this reversal – especially in low- and middle-income countries – are conflict, climate extremes and variability, and economic downturns. This crisis – exacerbated by the economic shocks stemming from the COVID-19 pandemic containment measures – underlines the urgent need to transform food systems for food security, improved nutrition and affordable healthy diets. This prompted FAO, the International Fund for Agricultural Development (IFAD), the United Nations Children’s Fund (UNICEF), the World Food Programme (WFP) and the World Health Organization (WHO) to focus the theme of The State of Food Security and Nutrition in the World 2021 on possible transformative pathways and portfolios of policies to achieve these objectives. This paper analyses 136 case studies received from a call for best practices in transforming food systems to improve the affordability of healthy diets and build resilience to the major drivers of food security and nutrition. These can help countries formulate context-specific portfolios of policies, investments and laws that integrate different sectors – environmental, health and social protection, among others – to move from siloed approaches to integrated food systems solutions. The findings in this brief have been adapted from the FAO report "The State of Food Security and Nutrition in the World 2021 – Transforming food systems for food security, improved nutrition and affordable healthy diets for all" (https://doi.org/10.4060/cb4474en).

Molecular Dynamics Simulation of Water between Metal Walls under Electric Field: Dielectric Response and Dynamics after Field Reversal

description: We study water between parallel metal walls under applied electric field accounting for the image effect at $T=298$ K. The electric field due to the surface charges serves to attract and orient nearby water molecules, while it tends to a constant determined by the mean surface charge density away from the walls. We find Stern boundary layers with thickness about $5$ $\rm Å$ and a homogeneously polarized bulk region. The molecules in the layers more sensitively respond to the applied field than in the bulk. As a result, the potential drop in the layers is larger than that in the bulk unless the cell length exceeds 10 nm. We also examine the hydrogen bonds, which tend to make small angles with respect to the walls in the layers even without applied field. The average local field considerably deviates from the classical Lorentz field and the local field fluctuations are very large in the bulk. If we suppose a nanometer-size sphere around each molecule, the local field contribution from its exterior is nearly equal to that from the continuum electrostatics and that from its interior yields the deviation from the classical Lorentz field. As a nonequilibrium problem, we investigate the dynamics after a reversal of applied field, where the relaxation is mostly caused by large-angle rotational jumps after 1 ps due to the presence of the hydrogen bond network. The molecules undergoing these jumps themselves form hydrogen-bonded clusters heterogeneously distributed in space.

description: Shortages of injectable drugs affect many cancer patients and providers in the U.S. today. Scholars and policymakers have recently begun to devote increased attention to these issues, but only a few tangible resources exist to guide clinical oncologists in developing strategies for dealing with drug shortages on a recurring basis. This article discusses existing information from the scholarly literature, policy analyses, and other relevant sources and seeks to provide practical ethical guidance to the broad audience of oncology professionals who are increasingly confronted with such cases in their practice. We begin by providing a brief overview of the history, causes, and regulatory context of oncology drug shortages in the U.S., followed by a discussion of ethical frameworks that have been proposed in this setting. We conclude with practical recommendations for ethical professional behavior in these increasingly common and challenging situations.
Revealing the circumstellar environment of the Herbig Be star VV Ser by emission line modelling
Creators: name: Tambovtseva, Larisa
Publisher: name: Zenodo
Year: 2018

description: Great progress in understanding the principal physical mechanisms acting in emitting regions and regulating accretion and outflow processes were achieved by non-LTE modelling of the emission spectra of Herbig AeBe stars. Nevertheless, modelling of individual stars opens new problems in the interpretation of these mechanisms. We present results of non-LTE modelling of the H-alpha and Br-gamma lines in the spectrum of the Herbig Be star VV Ser, as well as the comparison of the spatial extension of the line and continuum emitting regions obtained by infrared interferometric observations. VV Ser belongs to a subclass of the UX Ori type stars (UXORs) with large extinction and that are observed nearly edge-on through its dusty protoplanetary disk. We give possible different explanations of a mutual presence of the narrow single-peaked Br-gamma and wide double-peaked H-alpha line profiles of this star. The influence of the accreting matter, outflows in the form of a disk or polar wind, and dust scattering on the line profiles is shown. The results of modelling can be applied to young stars with large circumstellar extinction and to UXORs during their phase of its brightness minima.

description: We perform dynamical simulations of a two-dimensional active nematic fluid in coexistence with an isotropic fluid. Drops of active nematic become elongated, and an effective anchoring develops at the nematic-isotropic interface. The activity also causes an undulatory instability of the interface. This results in defects of positive topological charge being ejected into the nematic, leaving the interface with a diffuse negative charge. Quenching the active lyotropic fluid results in a steady state in which phase-separating domains are elongated and then torn apart by active stirring.

A Multiwavelength Glimpse of the End of Accretion in T Tauri Stars
Creators: name: Thanathibodee, Thanawuth
Publisher: name: Zenodo
Year: 2018

description: It is accepted that accretion of T Tauri Stars follows the magnetospheric accretion paradigm. Under this framework, the inner gas disk is truncated at a few stellar radii; material from the disk flows along the stellar magnetic field lines onto the star, producing accretion shocks near the stellar surface. However, it is still unclear how the accretion proceeds at very low accretion rates, or how accretion stops. Here we present observations and modeling of a number of low accretors covering a large parameter space, in a search for a possible connection between the properties of the inner gas disk and accretion onto the star. We apply magnetospheric accretion and accretion shock models to optical and near-infrared observations of accretion signatures to calculate mass accretion rates onto the star and estimate the geometry of the magnetosphere. The inner gas disk is probed by HST FUV spectroscopic observations of H2 lines. Our results give insights into the star-disk interface near the final stages of accretion.

Risk-limiting Economic Dispatch for Electricity Markets with Flexible Ramping Products

description: The expected increase in the penetration of renewables in the approaching decade urges the electricity market to introduce new products - in particular, flexible ramping products - to accommodate the renewables' variability and intermittency. CAISO and MISO are leading the design of the new products. However, it is not clear how such products may affect the electricity market. In this paper, we are specifically interested in assessing how the new products distort the optimal energy dispatch by comparing with the case without such products. The distortion may impose additional cost, which we term as the "distortion cost". Using a functional approach, we establish the relationship between the distortion cost and the key parameters of the new products, i.e., the up and down flexible ramping requirements. Such relationship yields a novel routine to efficiently construct the functions, which makes it possible to efficiently perform the minimal distortion cost energy dispatch while guaranteeing a given supply reliability level. Both theoretical analysis and simulation results suggest that smartly selecting the parameters may substantially reduce the distortion cost. We believe our approach can assist the ISOs with utilizing the ramping capacities in the system at the minimal distortion cost.

description: We discuss the nature of quantum field theories involving gravity that are classically scale-invariant. We show that gravitational radiative corrections are crucial in the determination of the nature of the vacuum state in such theories, which are renormalisable, technically natural, and can be asymptotically free in all dimensionless couplings. In the pure gravity case, we discuss the role of the Gauss-Bonnet term, and we find that Dimensional Transmutation (DT) à la Coleman-Weinberg leads to extrema of the effective action corresponding to nonzero values of the curvature, but such that these extrema are local maxima. In even the simplest extension of the theory to include scalar fields, we show that the same phenomenon can lead to extrema that are local minima of the effective action, with both non-zero curvature and non-zero scalar vacuum expectation values, leading to spontaneous generation of the Planck mass. Although we find an asymptotically free (AF) fixed point exists, unfortunately, no running of the couplings connect the region of DT to the basin of attraction of the AF fixed point. We also find there remains a flat direction for one of the conformal modes. We suggest that in more realistic models AF and DT could be compatible, and that the same scalar vacuum expectation values could be responsible both for DT and for spontaneous breaking of a Grand Unified gauge group.

title: "Klagemauer, Sozialberatung, Therapeut*in, Schwester/Bruder (…)" - außerunterrichtliche Herausforderungen für Lehrende in geförderten Deutschkursen für Erwachsene
Creators: name: Golser, Magdalena

description: Die Anforderungen an die Rolle als Deutschlehrende*r in geförderten Deutschkursen steigen stetig und gehen in der Praxis in der Regel weit über die geforderten Kompetenzen für diesen Berufszweig hinaus, was bei Lehrenden zu Rollenkonflikten führt, deren Lösung als Herausforderung betrachtet wird. In der Literatur finden sich bislang nur sehr wenige Studien und Arbeiten in Bezug auf die Herausforderungen, mit denen sich Unterrichtende in geförderten Deutschkursen konfrontiert sehen. Jedoch ist deren Betrachtung für die Praxis des Unterrichtens in geförderten Deutschkursen relevant, um diese in Zukunft besser lösen zu können und somit die Arbeitsbedingungen der Lehrkräfte und die Qualität des Förderangebots zu verbessern. Deshalb wurden die außerunterrichtlichen Herausforderungen für Lehrende in geförderten Deutschkursen als Untersuchungsgegenstand für die vorliegende Arbeit gewählt. Im Rahmen einer empirischen Studie wurden sechs problemzentrierte Interviews mit Lehrenden in geförderten Deutschkursen durchgeführt. Die Ergebnisse der Studie zeigten, dass sich die Lehrenden mit einer Reihe von Herausforderungen konfrontiert sehen, deren Gründe vor allem in den vielen Aufgaben und Rollen als Lehrkraft, den Umgang mit Trauma und Flucht, den Konflikten im Kurs sowie den kulturbezogenen Schwierigkeiten bzw. allgemein in der Spezifik der Zielgruppe liegen und zum Teil aufgrund mangelnder Unterstützung oder fehlender Kompetenz nicht gelöst werden können.

D1 and D5-brane giant gravitons on $AdS_3 \times S^3 \times S^3 \times S^1$

description: We construct various examples of 1/4-BPS giant gravitons embedded into the type IIB supergravity background $AdS_{3} \times S^{3}_{+} \times S^{3}_{-} \times S^{1}$ with pure R-R flux: two D1-brane giants wrapping 1-cycles in $AdS_{3}$ and $S^{3}_{+} \times S^{3}_{-}$, and one D5-brane giant wrapping a 4-cycle in $S^{3}_{+} \times S^{3}_{-}$ and the $S^{1}$. These D-branes are supported by angular momenta $α$ P on one 3-sphere and $(1-α)$ P on the other. We then construct a general class of 1/8-BPS D5-brane giant gravitons wrapping 4-cycles $Σ$ in $S^{3}_{+} \times S^{3}_{-}$ and the $S^{1}$. Here $Σ$ is the intersection of a holomorphic surface $\mathcal{C}$ in $\mathbb{C}^{2}_{+} \times \mathbb{C}^{2}_{-}$ with the $S^{3}_{+} \times S^{3}_{-}$ submanifold. The holomorphic surface $\mathcal{C}$ is defined by $f(y_{1}z_{1},y_{1}z_{2},y_{2}z_{1},y_{2}z_{2}) = 0$, with $y_{a}$ and $z_{a}$ the $\mathbb{C}^{2}_{\pm}$ complex coordinates. There is supersymmetry enhancement to 1/4-BPS in the special case $f(y_{1}z_{1}) = 0$ of which our original D5-brane giant graviton is an example.

PHARMACOLOGICAL AND FUNCTIONAL CHARACTERISATION OF NEURONAL NICOTINIC ACETYLCHOLINE RECEPTORS IN LUNG CANCER CELL LINES: A CHALLENGE FOR NEW THERAPEUTICAL STRATEGIES?
Creators: name: MUCCHIETTO, VANESSA

description: Lung cancer is the leading cause of cancer-related deaths worldwide and cigarette smoking is related to 90% of all deaths due to lung cancer. Tobacco smoke contains many classes of carcinogens and, although nicotine, the addictive and most active component of tobacco smoke, is unable to initiate tumourigenesis in humans and rodents, it promotes tumour growth and metastasis by inducing cell-cycle progression, cell migration, angiogenesis and the evasion of apoptosis in a variety of systems. Nicotine and its metabolites are highly lipophilic compounds that bind and activate a family of ligand-gated cation channels (the neuronal nicotinic acetylcholine receptors, nAChRs) that are widely expressed in the central and peripheral nervous systems. Over the last few decades, the extra-neuronal localisation of nAChRs has been demonstrated in a large number of cell types including endothelial cells, glia, immune cells, lung tissue and cancer cells, indicating that they might have functions well beyond simple neurotransmission. Recent studies have shown that most of the tumour-promoting effects of nicotine are primarily due to the binding and the activation of nAChRs, which lead to downstream intracellular signalling cascades. However, identifying the receptor subtypes expressed in lung tumour cells and their signalling pathways is still in its early stage. For these reasons, we investigated the pathophysiological role of nAChRs in lung cancer cells. We found that different non-small cell lung cancer (NSCLC) cells express distinctive nicotinic receptor subtypes and that this variety affects nicotine-induced proliferation and migration. In the A549 adenocarcinoma cell line, nAChRs containing the ?7, ?9 and ?5 subunits regulate not only the nicotine-induced cell proliferation and migration but also the activation of anti-apoptotic and proliferative pathways. Blocking nAChRs containing the ?7 or ?9 or ?5 subunits with specific toxins or silencing their expression by means of subunit-specific siRNAs abolishes the nicotine-induced proliferation, migration and signalling. Prompted by these results, we also studied oxystylbene compounds previously characterised by our group and started to syntehesise some new oxystylbene/resveratrol derivatives with specific modifications. We found that these 4-oxystilbene derivates act on both ?7 and ?9-containing receptors and block NSCLC cell proliferation and viability in a dose-dependent manner. These results highlight the pathophysiological role of specific nAChR subtypes in promoting NSCLC cell growth and migration and raise the possibility of targeting them in order to treat tobacco related cancer.
Magnetic Fields and Planets of Weak-line T Tauri Stars
Creators: name: Hill, Colin
Publisher: name: Zenodo
Year: 2018

description: T-Tauri stars are late-type pre-main-sequence stars that are gravitationally contracting towards the main sequence. Magnetic fields largely dictate the angular momentum evolution of these stars and can affect the formation and migration of planets. Thus, characterizing their magnetic fields is critical for testing and developing stellar dynamo models, and theories of low-mass star and planet formation. I will present the results so far of the MaTYSSE project, that aims to map the magnetic fields of weak-line T Tauri stars, and detect close-in giant planets.
title: Geschichtskultur - Darstellungen der Weimarer Republik anhand von "Berlin Alexanderplatz - die Geschichte vom Franz Biberkopf" und "Der nasse Fisch - Gereon Raths erster Fall"
Creators: name: Dai Zotti, Daniel
Year: 2022

description: Die vorliegende Arbeit befasst sich mit zwei geschichtskulturellen Produkten, welche die Weimarer Republik zum Thema haben. Die untersuchten Romane sind „Berlin Alexanderplatz“ von Alfred Döblin und „Der nasse Fisch“ von Volker Kutscher. Zunächst wird ein historischer Überblick der Weimarer Republik anhand von fünf Themen gegeben, um dann die Romane mit Hilfe von Rüsens Dimensionen der Geschichtskultur zu analysieren und miteinander zu vergleichen. Es wurde festgestellt, dass die Autoren sowohl über ähnliche als auch über ganz unterschiedliche Themen schreiben. Döblin konzentriert sich auf die Lebensbedingungen der Arbeiterklasse, während Kutscher großteils über die bürgerliche Klasse schreibt. Die Gemeinsamkeit besteht in der Beschreibung von nonkonformen Verhalten. Beide Autoren beschäftigen sich mit der Kriminalität, wobei Kutscher diese recht abenteuerlich beschreibt, wohingegen Döblin eine nüchterne Beschreibung liefert. Dieser Unterschied resultiert aus der zeitlichen Distanz zum Erzählungszeitraum. Döblin war Zeitzeuge und hatte als solcher keinen distanzierten Blick auf die Entwicklungen wie Kutscher. Döblin schrieb aus seiner Lebenswelt heraus, nicht über die politischen Veränderungen in Deutschland. Kutscher hingegen hat Zugang zu Quellen und Literatur. Er bettet die Erlebnisse des Gereon Rath in einen größeren historischen Zusammenhang ein, den der Protagonist zu deuten und damit umzugehen versucht.

Non-exponential tunneling ionization of atoms by an intense laser field

description: We discuss the possibility of non-exponential tunneling ionization of atoms irradiated by intense laser field. This effect can occur at times, which are greater than the lifetime of a system under consideration. The mechanism for non-exponential depletion of an initial quasi-stationary state is the cutting of the energy spectrum of final continuous states at long times. We first consider the known examples of cold emission of electrons from metal, tunneling alpha-decay of atomic nuclei, spontaneous decay in two-level systems and the single-photon atomic ionization by a weak electromagnetic field. The new physical situation discussed is tunneling ionization of atoms by a strong low-frequency electromagnetic field. In this case the decay obeys ~1/t power-law dependence on the (long) interaction times.

description: The application of effective field theory (EFT) methods to nuclear systems provides the opportunity to rigorously estimate the uncertainties originating in the nuclear Hamiltonian. Yet this is just one source of uncertainty in the observables predicted by calculations based on nuclear EFTs. We discuss the goals of uncertainty quantification in such calculations and outline a recipe to obtain statistically meaningful error bars for their predictions. We argue that the different sources of theory error can be accounted for within a Bayesian framework, as we illustrate using a toy model.

description: Geriatric assessment (GA) is an important tool for management of older cancer patients; however, GA research has been performed primarily in the outpatient setting. The primary objective of this study was to determine feasibility of GA during an unplanned hospital stay. Secondary objectives were to describe deficits found with GA, to assess whether clinicians recognized and addressed deficits, and to determine 30-day readmission rates.
