Beyond the exoplanet mass-radius relation
Authors: Ulmer-Moll S. , Santos N. C. , Figueira P. , Brinchmann J. , Faria J. P. 
Published: September 2019

Context.Mass and radius are two fundamental properties for characterising exoplanets, but only for a relatively small fraction of exoplanets are they both available. Mass is often derived from radial velocity measurements, while the radius is almost always measured using the transit method. For a large number of exoplanets, either the radius or the mass is unknown, while the host star has been characterised. Several mass-radius relations that are dependent on the planet’s type have been published that often allow us to predict the radius. The same is true for a bayesian code, which forecasts the radius of an exoplanet given the mass or vice versa.Aims.Our goal is to derive the radius of exoplanets using only observables extracted from spectra used primarily to determine radial velocities and spectral parameters. Our objective is to obtain a mass-radius relation independent of the planet’s type.Methods.We worked with a database of confirmed exoplanets with known radii and masses, as well as the planets from our Solar System. Using random forests, a machine learning algorithm, we computed the radius of exoplanets and compared the results to the published radii. In addition, we explored how the radius estimates compare to previously published mass-radius relations.Results.The estimated radii reproduces the spread in radius found for high mass planets better than previous mass-radius relations. The average radius error is 1.8R⊕across the whole range of radii from 1–22R⊕. We find that a random forest algorithm is able to derive reliable radii, especially for planets between 4R⊕and 20R⊕for which the error is under 25%. The algorithm has a low bias yet a high variance, which could be reduced by limiting the growth of the forest, or adding more data.Conclusions.The random forest algorithm is a promising method for deriving exoplanet properties. We show that the exoplanet’s mass and equilibrium temperature are the relevant properties that constrain the radius, and do so with higher accuracy than the previous methods.
Hyperfine excitation of CH and OH radicals by He
Authors: Marinakis S. , Kalugina Y. , Kłos J. , Lique F. 
Published: September 2019

Context. Because of their high reactivity, the CH and OH radicals are of particular interest in astrochemistry. Modeling of CH and OH molecules requires the calculation of accurate radiative Einstein coefficients and rate coefficients for (de)excitation by collisions with the most abundant species such as H2 and He.
Aims. The present paper focuses on the calculation of inelastic rate coefficients among the lowest OH/CH hyperfine levels in their ground vibrational state induced by collisions with He atoms.
Methods. Calculations of hyperfine (de)excitation of CH/OH by He were performed using the close-coupling and recoupling methods from the most recent ab initio potential energy surfaces.
Results. Cross sections for transitions among the 60 and 56 lowest hyperfine levels of CH and OH, respectively, were calculated for collision energies up to 2500 cm−1. These cross-sections were used to calculate the rate coefficients for temperatures between 10 and 300 K. A propensity rule for transitions with ΔF = Δj was observed.
Conclusions. The new rate coefficients will help significantly in interpreting the CH/OH spectroscopic data observed with current and future telescopes, and help to accurately describe the OH masers and the hyperfine anomalies in CH emission spectra.

Erlöseinbußen nach Einführung des G-DRG Systems durch schlechte Kodierqualität? Qualifikation der Kodierer an 177 deutschen Kinderkliniken
Authors: Zemlin Michael , Goedicke-Fritz Sybelle 
Published: September 2019

Hintergrund Die Pädiatrie wird häufig als „Verlierer“ des G-DRG-Systems angesehen, da sich seit Einführung des G-DRG-Systems im Jahr 2004 die wirtschaftliche Situation zahlreicher Kinderkliniken verschlechtert hat. Dies wird oft auf eine nicht kostendeckende Gewichtung der Fallpauschalen zurückgeführt. Bisher ist unbekannt, ob Erlöse durch mangelhafte Qualifikation der Kodierer verloren gehen.
Methode Alle in der Gesellschaft der Kinderkliniken und -abteilungen in Deutschland (GKinD) organisierten Kinderkliniken und Abteilungen wurden per E-Mail zu einer online-Umfrage eingeladen.
Ergebnisse 177 (52%) der 340 deutschen Kinderkliniken lieferten vollständig ausgefüllte Fragebögen. An 52% der Kliniken waren hauptamtliche Kodierer ohne klinische Aufgaben tätig. An 47% der Kliniken hatten die Kodierer für diese Tätigkeit keine spezifische berufliche Qualifikation und an 32% der Kliniken besuchten die Kodierer keine spezifischen Fortbildungsveranstaltungen. 35% der Kodierer wurden bei Abwesenheiten fachfremd oder gar nicht vertreten. Die Kodierstrukturen wurden von 2,8% der Kliniken als „schlecht“ oder „sehr schlecht“ beurteilt.
Diskussion An zahlreichen deutschen Kinderkliniken werden die medizinischen Leistungen von Mitarbeitern kodiert, die dafür ungenügend qualifiziert sind. Dies ist mit einem Risiko von fehlerhaften und unvollständigen Kodierungen verbunden und kann die wirtschaftliche Situation von Kinderkliniken gefährden. Die Zufriedenheit der ärztlichen Leiter und Leiterinnen mit den etablierten Kodierstrukturen deutet darauf hin, dass das ökonomische Potenzial von Verbesserungen der Kodierqualität wenig bekannt ist.
Schlussfolgerung Durch Einstellung von hauptamtlichen, qualifizierten Kodierern kann die wirtschaftliche Situation an vielen deutschen Kinderkliniken verbessert werden.
What's the Score? Do Pleural Effusion Clinical Scoring Systems Help in Management of Disease?
Authors: Grendelmeier Peter , Rahman Najib M. 
Published: September 2019

AbstractPleural effusion is a common condition, affecting over 3,000 people per million population every year. More than 50 causes of pleural effusions are known, including pleural infection and malignant pleural disease. These conditions place a large burden on healthcare systems with one-fourth of patients with pleural infection having a length of hospital stay of more than 1 month. Malignant pleural effusion represents advanced malignant disease with a correspondingly high mortality. Prognostic models using clinical information in combination with blood or pleural fluid biomarkers predicting survival and other outcome measures are therefore a priority in improving clinical care, and potentially outcomes. Identifying patients with poor prognosis may help avoid discomfort and unnecessary interventions at the end of their lives, while, on the other hand, individuals with scores predicting a particularly good prognosis might be selected for more aggressive early treatment. Such scores must be based on data representing routine practice in a general hospital and variables chosen based on their clinical availability at clinical decision points (i.e., before treatment is instituted), making the findings widely applicable.

AbstractTrisomy 9p syndrome is the fourth most frequent chromosome aberration seen in infants. Duplication of the critical region 9p22p24 leads to mental retardation, psychomotor delay, and craniofacial and digital anomalies. We report a 2-year-old Ecuadorian girl with Trisomy 9p syndrome. Although her phenotype shares characteristics of Noonan syndrome, Giemsa trypsin banding technique shows there is an extra chromosomal segment on chromosome 14, and array analysis shows that it belongs to a duplication of 38 Mb of 9p13.1p24.3. Fluorescence in situ hybridization analysis detected three signals from 9p chromosome. The duplication is de novo, being another unique case of the few reported in the literature.

Published: September 2019

ABSTRACT
The effect of Lactobacillus plantarum SNK12 (CPLP) supplementation on mRNA levels of hippocampal neurotrophic factors and gamma aminobutyric acid receptors (GABAR) was tested. In Experiment 1, stress-free, unsupplemented and CPLP (4 × 108 cells/head)-supplemented male C57BL/6J (B6) mice were the experimental animals. In Experiment 2, intruder (male, B6) mice [negative control; unsupplemented, sub-chronic mild social defeat stress (sCSDS)-induced; and CPLP-supplemented, sCSDS-induced] were exposed to aggressor mice (adult male Slc:ICR). mRNA levels of neurotrophic factors and GABAR in hippocampal samples of these mice were analyzed. In CPLP-supplemented mice of both experiments, mRNA levels of bdnf, nt-3, and GABAR were upregulated. Moreover, a tendency toward the improvement of habituation ability (Experiment 1) and behavior (Experiment 2) was observed in mice, which may be associated with upregulated neurotrophic factors and GABAR. We demonstrated that oral supplementation of CPLP to stress-free and stress-induced mice upregulated mRNA levels of hippocampal neurotrophic factors and GABAR.

Abstract
The aims of the study were to investigate characteristics of activated carbon prepared from banana peels as adsorbent for the removal gasesemission from motorcycles. The effect of differents chemocalactivators and contact time were studied on the characteristics of banana peels raw carbon (RC) and chemically activated carbon (CAC) such as moisture content, ash content, volatile matter. The best ofIodine adsorption capacity of CAC H2SO4 3N 3 hour contact, was obtained at 913,68 mg/g adsorbent. Structure and morphology ofRC and CAC were characterized by Fourier transform infrared (FTIR) and field emission scanning electron microscopy (SEM). The results showed that RC and CAC could significantly adsorbed the CO and SO2gasesemissions from motorcycles, but not applicable for NO, NOx gases. After 10 minutes analysis using gas emission Analyzer, CO gas could be removed, from initial 16014 ppm to 3578 ppm using CAC H2SO4 adsorbent, while SO2 gas could also be partly removed from 217 ppm to 19 ppm using CAC ZnCl2 adsorbent.Banana peels carbon produced was suitable for application in removing CO and SO2gases emissions from motorcycles and it helps to reduce the green house gas effects of fossil fuel usage to the environment.

Published: September 2019

Abstract
The activated ilmenite nanocomposite of TiO2 hybridized were prepared by natural ilmenite and commercial TiO2 anatase assembled using sugar as cross-link agents and carbon source. The heterostructure interface of anatase-ilmenite junction, crystallinity and chemical state were characterized by X-ray diffraction (XRD), UV-Vis diffuse reflectance spectroscopy and X-ray photoelectron spectroscopy (XPS). Composite morphologies and structures were investigated by scanning electron microscope (SEM). Synergistic of low energy gap in range of visible light and interfacial charge separate from TiO2 to ilmenite junction was evaluated in photocatalytic degradation of organic dye. The result from visible light catalytic dye degradation suggests that narrow bandgap energy is associated to ilmenite phase and sensitization by carbon with low recombination rate of generated electron-hole pair transfer. This mechanism occurred by multiphase junction could enhance visible light photocatalytic activity.

Published: September 2019

Abstract
Hybrid optical gas sensors based on Al-doped ZnO/Zinc porphyrin (AZO/ZnTPP) thin films have been fabricated and demonstrated to detect ethanol vapor. Double-sensing layer of AZO and ZnTPP films were deposited on a cleaned glass substrate by RF magnetron sputtering and spin-coating techniques, respectively. We have investigated the influences of Al-doping concentration (0%, 2% and 3 wt% Al2O3) on ZnO structure with regarding to enhancing optical gas sensing properties when exposed the films to the volatile. Structural, electrical and optical properties of the AZO thin films were characterized and related to the optical gas sensing responses. It was found that an increase of Al-doped concentration in ZnO structure can also induce a potentially optical sensing response. These results were mentioned that an enhancement of carrier concentration due to Al3+ substitution in Zn2+ on ZnO structure can generate the adsorbed oxygen ion on the AZO surface as well. Absorption spectra of AZO thin films showed blue shift in near UV region due to releasing of electrons when the adsorbed oxygen ions were interacted with ethanol molecules. According to the introduced the AZO layer to form AZO/ZnTPP sensing film, the results could be demonstrated significantly enhanced the optical responses to the ethanol in broaden range of near UV-visible region at room temperature. Finally, the authors have suggest that the A3ZO/ZnTPP thin film exhibiting a good performance to detect ethanol vapor and overcome a conventional ZnTPP, ZnO/ZnTPP and A2ZO/ZnTPP thin films may be promoted as one of the optical gas sensor in an optoelectronic nose system due to broaden responses at room temperature.
