Evolution of a migrating giant planet in the presence of an inclined binary companion
Authors: Roisin A. , Libert A.-S. 
Published: October 2020

Aims. There are a growing number of giant planets discovered moving around one stellar component of a binary star, most of which have very diverse eccentricity. These discoveries raise the question of their formation and long-term evolution because the stellar companion can strongly affect the planet formation process. We aim to study the dynamical influence of a wide binary companion on the evolution of a single giant planet migrating in a protoplanetary disk.
Methods. Using a symplectic N-body integrator adapted for binary star systems and modeling the dissipation due to the disk by appropriate formulae emerging from hydrodynamical simulations, we carried out 3200 simulations with different orbital parameters for the planet and different eccentricity and inclination values for the binary companion. The long-term evolution of the planets was followed for 100 Myr and the different dynamical behaviors were unveiled using a quadrupolar Hamiltonian approach.
Results. We show that a capture in a Lidov-Kozai resonant state is far from automatic when the binary companion star is highly inclined, since only 36% of the systems end up locked in the resonance at the end of the simulations. Nevertheless, in the presence of a highly inclined binary companion, all the planetary evolutions are strongly influenced by the Lidov-Kozai resonance and the nonresonant evolutions present high eccentricity and inclination variations associated with circulation around the Lidov-Kozai islands.
The spin-orbit alignment of visual binaries
Authors: Justesen A. B. , Albrecht S. 
Published: October 2020

Context. The angle between the stellar spin-axis and the orbital plane of a stellar or planetary companion has important implications for the formation and evolution of such systems. A study by Hale (1994, AJ, 107, 306) found that binaries with separations a ≲ 30 au are preferentially aligned while binaries on wider orbits are frequently misaligned.
Aims. We aim to test the robustness of the Hale study results by reanalysing the sample of visual binaries with measured rotation periods using independently derived stellar parameters and a Bayesian formalism.
Methods. Our analysis is based on a combination of data from the Hale study and newly obtained spectroscopic data from the Hertzsprung SONG telescope, combined with astrometric data from Gaia DR2 and the Washington Double Star Catalog. We combine measurements of stellar radii and rotation periods to obtain stellar rotational velocities v. Rotational velocities v are combined with measurements of projected rotational velocities v sin i to derive posterior probability distributions of stellar inclination angles i. We determine line-of-sight projected spin-orbit angles by comparing stellar inclination angles with astrometric orbital inclination angles.
Results. We find that the precision of the available data is insufficient to make inferences about the spin-orbit alignment of visual binaries. The data are equally compatible with alignment and misalignment at all orbital separations.
Conclusions. We conclude that the previously reported trend that binaries with separations a ≲ 30 au are preferentially aligned is spurious. The spin-orbit alignment distribution of visual binaries is unconstrained. Based on simulated observations, we predict that it will be difficult to reach the sufficient precision in v sin i, rotation periods, and orbital inclination required to make robust statistical inferences about the spin-orbit alignment of visual binaries.

Published: October 2020

Context.The colour-ratio technique has been widely used in mapping planetary surfaces, but its solar phase-angle dependence is not well understood. Understanding the phase-angle dependence of the colour ratio would enhance our abilities in interpreting planetary remote sensing data.Aims.We aim to investigate the dependence of the colour ratio indices on mineralogy, phase angle, particle size, and the degree of simulated space weathering.Methods.We measured the multi-band (i.e. 458, 633, 750, and 905 nm) and multi-angle reflectance spectra of four typical lunar-type minerals with different particle sizes using a custom multi-angular imaging device.Results.The colour ratio does have a phase-angle dependence that is more sensitive to the mineralogy and wavelength and less sensitive to particle size distribution.Conclusions.The combined analysis of the colour ratio and its phase dependence can improve efficiency in mapping the lunar surface. With a prior knowledge of the phase behaviours of colour ratios of specific lunar-type minerals, an optimised colour ratio at certain phase angles can be found to efficiently distinguish the composition of a target surface.
Pankreasinsuffizienz – oft spät erkannt: Was kann die Ernährungstherapie leisten?
Authors: Jagemann Bettina , Manthey Carolin 
Published: October 2020

ZusammenfassungPankreaserkrankungen unterschiedlicher Genese führen langfristig zu Mangelernährung und Stoffwechselstörungen (z. B. pankreopriver Diabetes), wenn die Funktionsstörungen nicht medikamentös und diätetisch unterstützt werden.Obwohl das Pankreas mit einer Länge von ca. 15 cm und einem Gewicht von 120–150 g zu den kleinsten Organen des menschlichen Körpers zählt, spielt es für die Nährstoffversorgung des Menschen eine zentrale Rolle. Kein anderes Organ produziert täglich mehr Eiweiße (30–60 g/Tag; Leber im Vergleich: 15–50 g Eiweißproduktion) und auch die Sekretproduktion ist für die Größe des Organs mit 1,5–3 L beachtlich, davon 1–1,5 L Bauchspeichel.Da die klinischen Symptome einer Pankreaserkrankung unspezifisch sein können und Überlappungen zu vielen anderen Erkrankungen haben, wie zum Beispiel den Nahrungsmittelunverträglichkeiten, ist die Diagnosestellung schwierig. Insbesondere Einschränkungen der exokrinen Organfunktion führen zu schleichender Gewichtsabnahme und Mangelernährung, die in den meisten Fällen viel zu spät erkannt wird und den Verlauf der Erkrankung negativ beeinflussen kann. Dargestellt werden soll daher, wie eine frühzeitige begleitende Ernährungstherapie sowohl die Diagnostik unterstützen als auch frühzeitig Mangelzuständen entgegenwirken kann.

Published: October 2020

Zusammenfassung
Ziel Durch die Zunahme soziokultureller Vielfalt steigt auch im deutschen Gesundheitswesen die Bedeutung interkultureller Öffnungsprozesse. Die vorliegende Studie untersucht anhand von 4 Fallbeispielen, inwiefern eine organisational angelegte interkulturelle Öffnung (IKÖ) sich auf system- und sozialintegrativer Ebene auswirkt. Auf Basis der empirischen Ergebnisse können praxisorientierte Handlungsempfehlungen abgeleitet werden.
Methodik Mittels sozialwissenschaftlicher qualitativer Methoden wurde an 21 Beobachtungstagen in 2 Krankenhäusern und 2 ambulanten Pflegediensten in NRW eine teilnehmende Beobachtung durchgeführt. Die untersuchten Einrichtungen unterschieden sich hinsichtlich des interkulturellen Öffnungsgrades. Die Beobachtungen wurden systematisch protokolliert und anhand der dokumentarischen Methode mit MAXQDA induktiv kategorienbasiert ausgewertet. Die Herangehensweise knüpft an die Bourdieu’sche Feld-Habitus-Theorie 7 und die Beobachtungsfelder wurden in Anlehnung an Lockwood auf system- und sozialintegrativer Ebene 8 analysiert.
Ergebnisse Das ausgearbeitete Kategoriensystem setzt sich aus 4 Hauptkategorien (Methodologie, Arbeitsorganisation, Kommunikation, Pflege- und Medizinsystem) und 918 Sub-Kategorien zusammen. Eine interkulturelle Öffnung der Organisation in Form von einem interkulturellen Team und angebotenen Maßnahmen zur interkulturellen Öffnung gehen mit einem höheren Maß an Solidarität einher.
Schlussfolgerungen Der interkulturelle Öffnungsprozess im Gesundheitswesen ist auf system- und auf sozialintegrativer Ebene zu verankern, um effizientere Versorgungsabläufe und einen solidarischen Umgang zu befördern. Da IKÖ mit zusätzlichen zeitlichen, finanziellen und personellen Ressourcen verbunden ist, braucht es von Seiten der Geschäftsführung eine strategische Entscheidung einerseits und einen von oben bewusst gesteuerten Öffnungsprozess andererseits. Dieser ermöglicht es den Mitarbeitenden, die traditionelle Organisationskultur in einem Aushandlungsprozess partizipativ mitzugestalten.

Abstract
Purpose To evaluate the effectiveness of cabergoline and the parameters affecting cabergoline response as add-on treatment to somatostatin analaogues (SSA) in patients with acromegaly uncontrolled with SSAs.
Material and Method One hundred and twenty-nine acromegalic patients uncontrolled with SSA who had cabergoline added to their treatment were included in this retrospective study. Patients were divided into the SSAs + cabergoline-responsive (group 1) and non-responsive groups (group 2), and biochemical, pathologic, and radiologic parameters were assessed.
Results IGF-1 normalization was achieved in 75 of 129 patients (58%) when cabergoline was added to the SSA treatment. Female patients were significantly higher in group 1 compared to group 2 (p=0.006). Group 1 had significantly smaller pre- and post-cabergoline tumor size (p=0.011, p=0.007 respectively), lower levels of IGF-1 in pre-and post-operative period (p=0.040, p=0.001), and lower levels of IGF-1 in pre- and post-cabergoline treatment (p<0.001). Cavernous invasion on sellar magnetic resonance imaging, dural invasion in pathologic examination were not significantly different between the groups. Sellar invasion in pathologic examination was significantly higher in group 1 (p=0.011). No significant difference was found in proliferation indices between two groups. The presence of fibrous bodies was significantly lower in group 1 (p=0.010).
Conclusion Cabergoline can be added to the treatment of acromegalic patients uncontrolled with SSAs due to its ease of use and low economic cost, especially in patients with acromegaly who have small adenomas and no fibrous bodies.
C–H Alkylation of Heteroarenes with Alkyl Oxalates by Molecular Photoelectrocatalysis
Authors: Xu Hai-Chao , Xu Fan , Lai Xiao-Li 
Published: October 2020

AbstractAn oxidant- and metal-free photoelectrocatalytic C–H alkylation reaction of heteroarenes with alkyl oxalates has been developed. Several classes of heteroaromatics, such as quinolines, isoquinolines, pyridines, and phenanthridines, can be alkylated with tertiary or secondary alkyl oxalates. The photoelectrochemical synthesis employs 2,4,5,6-tetra-9H-carbazol-9-ylisophthalonitrile as a molecular catalyst and allows the oxidative transformations to proceed through evolution of hydrogen without a sacrificial chemical oxidant.

Significance
HPV+ HNSCC is a growing problem in the United States. We show that HPV16 E6/E7 render HNSCC sensitive to WEE1 inhibition through a CDK1-FOXM1 circuit that drives premature mitosis and requires E6 activities beyond p53 inactivation. Primary HPV+ HNSCCs exhibit high FOXM1 activity, which may underlie their sensitivity to WEE1 inhibition. These data provide a mechanistic rationale for WEE1i incorporation into HPV+ HNSCC treatment.
Amyloid formation of fish β-parvalbumin involves primary nucleation triggered by disulfide-bridged protein dimers

Published: October 2020

Significance
Amyloid fibrils are generally related to neurodegenerative diseases, but they can also be part of normal protein function. Amyloid formation involves numerous steps and intermediate species. In this study, we investigated a fish protein, beta-parvalbumin, which readily forms amyloid on ligand removal. Using biophysical experiments, we provide evidence that the underlying mechanism of amyloid formation includes primary nucleation and elongation processes; we also reveal a key role for a disulfide-bridged dimer in the nucleation step. Little is known about intermolecular disulfides in amyloid formation, but covalent dimers and dimer-induced aggregation may be of clinical relevance, because oxidative stress, which can trigger covalent bond formation, is often a hallmark of human neurodegenerative diseases.
Study of multi-window electromagnetically induced transparency (EIT) and related dispersive signals in V-type systems in the Zeeman sublevels of hyperfine states of87Rb-D2line
Authors: Hazra Rohit , Hossain Md Mabud 
Published: October 2020

AbstractWe have theoretically studied the multi-window electromagnetically induced transparency (EIT) and the related dispersive signals in multi-level V-type systems which are formed by the co-propagating circularly polarized pump (σ−) and probe (σ+) laser fields in the Zeeman sublevels of hyperfine states of87Rb-D2line. The optical Bloch equations (OBEs) are derived and numerically solved under the steady-state condition to obtain the probe absorption and dispersion spectra. We present the study of a single-window EIT for the three-level, double-window EIT for the four-level and triple-window EIT for the five-level V-type systems under both Doppler-free and Doppler-broadened conditions. The dispersive signals corresponding to the multi EIT windows for each system are also observed separately. From the knowledge of the slopes of the probe dispersion signals, we have calculated group index (ng) of the medium considering three different V-type schemes. The effect of temperature on the EIT, dispersion and group index profiles is also studied in detail. It is found that the amplitudes of EIT and dispersion signals and also the positive and negative values ofngare decreased as the temperature of the medium increases. To understand the Doppler-broadening effect on the group index profiles, we have considered three different velocity groups of atoms in the calculation of group index profiles. Moreover, the effects of probe intensity variation on the Doppler-broadened EIT and dispersive signals are studied extensively, and the conversions of EIT to EIA and dispersive positive slope to negative slope are observed under strong probe regime. Also, we have investigated the variation of dispersive slope and group index with the variation of probe intensity and probe frequency, respectively, at the multi-frequency position of the multi-window EIT. Finally, the switching between subluminal (slow light) to superluminal (fast light) propagation of light with the variation of both probe intensity and probe frequency is discussed in detail.
Thickness-dependent ultrafast hot carrier and phonon dynamics of PtSe2 films measured with femtosecond transient optical spectroscopy

Published: October 2020

Abstract
We systematically investigate the ultrafast hot carrier and phonon dynamics of PtSe2 with various van der Waals (vdW) layer numbers using femtosecond transient optical spectroscopy. The hot carrier dynamics of PtSe2 is found to be strongly dependent on its thickness. For semiconducting PtSe2 films (≤4 vdW layers), electron–phonon coupling, interlayer charge transfer and nonradiative recombination of electrons and holes contribute to the hot carrier decay, while electron–phonon coupling dominates the carrier decay in metallic PtSe2 films (with

vdW layers). The PtSe2 films with 2 vdW layers show the most pronounced interlayer charge transfer decay process and are thus most suitable for photoelectric sensors and energy harvesting devices. The phonon dynamics of PtSe2 is also thickness dependent; its LB mode phonon frequency decreases as the number of vdW layers increases, as a result of the thickness-dependent dielectric screening of the long-range Coulomb interaction.
Ignition phase of a typical plasma scalpel
Authors: Wu Fan , Li JiaYin , Liu FengWu , Lu XinPei 
Published: October 2020

Abstract
A plasma scalpel is one of the few applications of plasma medicine widely used in the clinic, but its ignition mechanism is poorly understood. This paper investigates the ignition phase of a plasma scalpel by obtaining the electrical waveforms, vaporization dynamics, plasma production and the plasma spectrum. Additionally, equivalent circuit and physical models are proposed based on the results. Two kinds of vapor layers are formed in plasma production. One is produced by Joule heating, which occurrs at the initial stage and the other is maintained by plasma heating at the stable discharge stage. When the plasma is generated, the vapor layer will become much thinner, leading to a significant increase in the electric field. The waveforms indicate the discharge has two kinds of patterns: asymmetric and symmetric patterns. The plasma intensity in the asymmetric is much stronger than the symmetric pattern. The fitted OH spectrum reveals that the gas temperature of the plasma can reach 2600 K, which can sustain the thin vapor layer. According to the broadening of the Hα line, the electron density is estimated to be about 7.1 × 1015 cm−3. Furthermore, when the stable vapor layer is formed, the impedance of the gap increases from 70 Ω to 2000 Ω when the plasma is established. The electron density is estimated again according to the plasma impedance to be about 1015–1016 cm−3.

Published: October 2020

Abstract
The coupling system with dynamic manipulation characteristics is of great importance for the field of active plasmonics and tunable metamaterials. However, the traditional metal-based architectures suffer from a lack of electrical tunability. In this study, a metamaterial composed of perpendicular or parallel graphene-Al2O3-graphene stacks is proposed and demonstrated, which allows for the electric modulation of both graphene layers simultaneously. The resultant absorption of hybridized modes can be modulated to more than 50% by applying an external voltage, and the absorption bandwidth can reach 3.55 μm, which is 1.7 times enhanced than the counterpart of single-layer graphene. The modeling results demonstrate that the small relaxation time of graphene is of great importance to realize the broadband absorption. Moreover, the optical behaviors of the tunable metamaterial can be influenced by the incident polarization, the dielectric thickness, and especially by the Fermi energy of graphene. This work is of a crucial role in the design and fabrication of graphene-based broadband optical and optoelectronic devices.
One-dimensional twisted and tubular structures of zinc oxide by semiconductor-catalyzed vapor–liquid–solid synthesis

Published: October 2020

Abstract
The exploration of unconventional catalysts for the vapor–liquid–solid synthesis of one-dimensional materials promises to yield new morphologies and functionality. Here, we show, for the model ZnO system, that unusual nanostructures can be produced via a semiconductor (Ge) catalyst. As well as the usual straight nanowires, we describe two other distinct morphologies: twisted nanowires and twisted nanotubes. The twisted nanotubes show large hollow cores and surprisingly high twisting rates, up to 9°/μm, that cannot be easily explained through the Eshelby twist model. A combination of ex situ and in situ transmission electron microscopy measurements suggest that the hollow core results from a competition between growth and etching at the Ge–ZnO interface during synthesis. The twisting rate is consistent with a softening of elastic rigidity. These results indicate that the use of unconventional, nonmetallic catalysts provides opportunities to synthesize unusual oxide nanostructures with potentially useful properties.
Features of non-classical light during its interaction with atoms and semiconductor nano-systems

Published: October 2020

Abstract
The interactions of a three-level atomic system with a single mode of quantized field is investigated analytically. The effect of coherent population trapping is demonstrated for an arbitrary initial quantum field state and the peculiarities of this regime in squeezed vacuum light are found. Mutual influence between atomic and field subsystems and their entanglement arising during the interaction is demonstrated. A significant change of the field state during the interaction is shown. The possibility of photon bunching and anti-bunching and the formation of a quantum field with non-Gaussian properties is found.
Microscopic approach to the macrodynamics of matter with broken symmetries
Authors: Mabillard Joël , Gaspard Pierre 
Published: October 2020

Abstract
A unified set of hydrodynamic equations describing condensed phases of matter with broken continuous symmetries is derived using a generalization of the statistical-mechanical approach based on the local equilibrium distribution. The dissipativeless and dissipative parts of the current densities and the entropy production are systematically deduced in this approach by expanding in powers of the gradients of the macrofields. Green–Kubo formulas are obtained for all the linear transport coefficients. The consequences of microreversibility and spatial symmetries are investigated, leading to the prediction of cross effects resulting from Onsager–Casimir reciprocal relations. Crystalline solids and liquid crystals are potential examples of application. The approach is clarifying the links between the microscopic Hamiltonian dynamics and the thermodynamic and transport properties at the macroscale.
