Context. Persistent tension between low-redshift observations and the cosmic microwave background radiation (CMB), in terms of two fundamental distance scales set by the sound horizon rd and the Hubble constant H0, suggests new physics beyond the Standard Model, departures from concordance cosmology, or residual systematics.
Aims. The role of different probe combinations must be assessed, as well as of different physical models that can alter the expansion history of the Universe and the inferred cosmological parameters.
Methods. We examined recently updated distance calibrations from Cepheids, gravitational lensing time-delay observations, and the tip of the red giant branch. Calibrating the baryon acoustic oscillations and type Ia supernovae with combinations of the distance indicators, we obtained a joint and self-consistent measurement of H0 and rd at low redshift, independent of cosmological models and CMB inference. In an attempt to alleviate the tension between late-time and CMB-based measurements, we considered four extensions of the standard ΛCDM model.
Results. The sound horizon from our different measurements is rd = (137 ± 3stat. ± 2syst.) Mpc based on absolute distance calibration from gravitational lensing and the cosmic distance ladder. Depending on the adopted distance indicators, the combined tension in H0 and rd ranges between 2.3 and 5.1 σ, and it is independent of changes to the low-redshift expansion history. We find that modifications of ΛCDM that change the physics after recombination fail to provide a solution to the problem, for the reason that they only resolve the tension in H0, while the tension in rd remains unchanged. Pre-recombination extensions (with early dark energy or the effective number of neutrinos Neff = 3.24 ± 0.16) are allowed by the data, unless the calibration from Cepheids is included.
Conclusions. Results from time-delay lenses are consistent with those from distance-ladder calibrations and point to a discrepancy between absolute distance scales measured from the CMB (assuming the standard cosmological model) and late-time observations. New proposals to resolve this tension should be examined with respect to reconciling not only the Hubble constant but also the sound horizon derived from the CMB and other cosmological probes.
Toward a large bandwidth photonic correlator for infrared heterodyne interferometry
Authors: Bourdarot G. , Guillet de Chatellus H. , Berger J-P. 
Published: June 2020

Context. Infrared heterodyne interferometry has been proposed as a practical alternative for recombining a large number of telescopes over kilometric baselines in the mid-infrared. However, the current limited correlation capacities impose strong restrictions on the sensitivity of this appealing technique.
Aims. In this paper, we propose to address the problem of transport and correlation of wide-bandwidth signals over kilometric distances by introducing photonic processing in infrared heterodyne interferometry.
Methods. We describe the architecture of a photonic double-sideband correlator for two telescopes, along with the experimental demonstration of this concept on a proof-of-principle test bed.
Results. We demonstrate the a posteriori correlation of two infrared signals previously generated on a two-telescope simulator in a double-sideband photonic correlator. A degradation of the signal-to-noise ratio of 13%, equivalent to a noise factor NF = 1.15, is obtained through the correlator, and the temporal coherence properties of our input signals are retrieved from these measurements.
Conclusions. Our results demonstrate that photonic processing can be used to correlate heterodyne signals with a potentially large increase of detection bandwidth. These developments open the way to photonic processing of wide bandwidth signals for mid-infrared heterodyne interferometry, in particular for a large number of telescopes and for direct imager recombiners.

Context. LDN 1157 is one of several clouds that are situated in the cloud complex LDN 1147/1158. The cloud presents a coma-shaped morphology with a well-collimated bipolar outflow emanating from a Class 0 protostar, LDN 1157-mm, that resides deep inside the cloud.
Aims. The main goals of this work are (a) mapping the intercloud magnetic field (ICMF) geometry of the region surrounding LDN 1157 to investigate its relationship with the cloud morphology, outflow direction, and core magnetic field (CMF) geometry inferred from the millimeter- and submillimeter polarization results from the literature, and (b) to investigate the kinematic structure of the cloud.
Methods. We carried out optical (R-band) polarization observations of the stars projected on the cloud to map the parsec-scale magnetic field geometry. We made spectroscopic observations of the entire cloud in the 12CO, C18O, and N2H+ (J = 1–0) lines to investigate its kinematic structure.
Results. We obtained a distance of 340 ± 3 pc to the LDN 1147/1158, complex based on the Gaia DR2 parallaxes and proper motion values of the three young stellar objects (YSOs) associated with the complex. A single filament of ~1.2 pc in length (traced by the Filfinder algorithm) and ~0.09 pc in width (estimated using the Radfil algorithm) is found to run throughout the coma-shaped cloud. Based on the relationships between the ICMF, CMF, filament orientations, outflow direction, and the hourglass morphology of the magnetic field, it is likely that the magnetic field played an important role in the star formation process in LDN 1157. LDN 1157-mm is embedded in one of the two high-density peaks detected using the Clumpfind algorithm. The two detected clumps lie on the filament and show a blue-red asymmetry in the 12CO line. The C18O emission is well correlated with the filament and presents a coherent structure in velocity space. Combining the proper motions of the YSOs and the radial velocity of LDN 1147/1158 and an another complex, LDN 1172/1174, that is situated ~2° east of it, we found that the two complexes are moving collectively toward the Galactic plane. The filamentary morphology of the east-west segment of LDN 1157 may have formed as a result of mass lost by ablation through interaction of the moving cloud with the ambient interstellar medium.

Published: June 2020

Context.The Perseus cluster is one of the most massive nearby galaxy clusters and is fascinating in various respects. Though the galaxies in the central cluster region have been intensively investigated, an analysis of the galaxy population in a larger field is still outstanding.Aims.This paper investigates the galaxies that are brighter thanB ≈ 20 within a field corresponding to the Abell radius of the Perseus cluster. Our first aim is to compile a new catalogue in a wide field around the centre of the Perseus cluster. The second aim of this study is to employ this catalogue for a systematic study of the cluster galaxy population with an emphasis on morphology and activity.Methods.We selected the galaxies in a 10 square degrees field of the Perseus cluster on Schmidt CCD images in B and Hαin combination with SDSS images. Morphological information was obtained both from the “eyeball” inspection and the surface brightness profile analysis. We obtained low-resolution spectra for 82 galaxies and exploited the spectra archive of SDSS and redshift data from the literature.Results.We present a catalogue of 1294 galaxies with morphological information for 90% of the galaxies and spectroscopic redshifts for 24% of them. We selected a heterogeneous sample of 313 spectroscopically confirmed cluster members and two different magnitude-limited samples with incomplete redshift data. These galaxy samples were used to derive such properties as the projected radial velocity dispersion profile, projected radial density profile, galaxy luminosity function, supermassive black hole mass function, total stellar mass, virial mass, and virial radius, to search for indications of substructure, to select active galaxies, and to study the relation between morphology, activity, density, and position. In addition, we present brief individual descriptions of 18 cluster galaxies with conspicuous morphological peculiarities.

ZusammenfassungDie flächendeckende Verbreitung erfolgreicher Interventionen der Gesundheitsförderung ist eine wichtige Voraussetzung, um messbare und nachhaltige Gesundheitswirkungen auf Bevölkerungsebene zu erzielen. Das Konzept des Scaling-Up bietet Ansätze, um Pilotinterventionen auf andere Standorte oder ganze Systeme zu übertragen und sie so einer Vielzahl von Menschen zugänglich zu machen. Dieser Beitrag möchte für den deutschsprachigen Raum auf Basis einer Literatur-Review einen ersten Überblick über einige theoretische Scaling-Up-Modelle sowie praktische Leitlinien für ein erfolgreiches Scaling-Up geben. Der Blick in die aktuelle Forschung liefert wichtige Erkenntnisse zur Definition von Scaling-Up und von damit verbundenen Konzepten, den verschiedenen Typen von Scaling-Up, zu zentralen Akteuren und ihren spezifischen Rollen, zum Ablauf von Scaling-Up-Prozessen sowie zu begünstigenden und hinderlichen Kontextfaktoren für erfolgreiches Scaling-Up. Damit kann dieser Artikel einerseits die Planung und praktische Umsetzung konkreter Scaling-Up-Vorhaben unterstützen und andererseits Anregungen für die weitere Forschung auf diesem Gebiet bieten.

Published: June 2020

Zusammenfassung
Hintergrund Soziale Medien (Social Media) spielen sowohl in der Freizeit als auch im medizinischen Berufsleben zunehmend eine wichtige Rolle. Gesellschaften wie die Föderation der Europäischen Gesellschaften für Handchirurgie (FESSH) tragen der Bedeutung von Social Media Rechnung, indem sie Social-Media-Gremien eingerichtet haben. Über die Nutzung von sozialen Medien in der und für die Handchirurgie gibt es bis dato keine Publikationen.
Ziel Das Ziel dieser Studie war es, die derzeitige Nutzung sozialer Medien in der und für die Handchirurgie am Beispiel von Instagram zu analysieren.
Material und Methoden Jeweils die ersten 100 Top-Beiträge (Posts), die im Juli 2019 auf Instagram mit den Hashtags #handsurgery, #handsurgeon und #fessh veröffentlicht wurden, wurden in Hinblick auf Autor, Thema und Art des Beitrags sowie die Reaktion auf den Beitrag ausgewertet.
Ergebnisse 101 der 300 Beiträge stammten von Handchirurgen. Die meisten Beiträge (172 = 57,3 %) waren Eigenwerbung; 41 (13,7 %) dienten der Vermittlung medizinischen Wissens. 199 (66,3 %) Beiträge beinhaltete nur ein Foto, 63 (21,0 %) Beiträge zwei oder mehr Fotos, 38 (12,7 %) ein Video. Video-Beiträge und Beiträge von Handtherapeuten erhielten die meisten Likes und Kommentare.
Schlussfolgerung Soziale Medien werden für die Handchirurgie zur Eigenwerbung, aber auch zur Wissensvermittlung genutzt. Video-Beiträge werden von der Social-Media-Gemeinde besser bewertet als Foto-Posts.

Zusammenfassung
Ziel Die vorliegende Studie untersucht, ob es eine Korrelation zwischen der Schwere der Stenosierung des N. medianus im Karpalkanal sowie dem Geschlecht und Alter von Patienten mit einem Karpaltunnelsyndrom und der distalen motorischen Latenz des Nervens gibt.
Patienten und Methoden Bei 82 Patienten (59 Frauen und 23 Männer mit einem Durchschnittsalter von 66,6 (41–89) Jahren) wurde bei elektrophysiologisch gesichertem Karpaltunnelsyndrom (KTS) während der offenen Karpaltunnelspaltung mit einer sterilen Schieblehre der Durchmesser des N. medianus an seiner engsten Stelle in Höhe der Stenose und an seiner breitesten Stelle proximal davon gemessen und dann ins Verhältnis gesetzt als Grad der Einengung. Der Grad der Einengung wurde mit der distalen motorischen Latenz (dmL) des N. medianus sowie dem Alter und Geschlecht der Patienten korreliert. Des Weiteren wurden die Messdaten von Frauen und Männern miteinander verglichen.
Ergebnisse Der Durchmesser des N. medianus an seiner engsten Stelle im Karpalkanal betrug im Durchschnitt 6,0 (SD 1,1) mm, an seiner breitesten Stelle proximal der Stenose durchschnittlich 7,6 (SD 1,5) mm. Die durchschnittliche Entfernung der Stenose zur Raszetta betrug 17,6 (SD 3,7) mm. Die distale motorische Latenz betrug im Durchschnitt 6,4 ms. Eine Korrelation zwischen dem Grad der Einengung des Nervens und seiner distalen motorischen Latenz fand sich nicht. Hingegen bestand eine positive Korrelation zwischen Alter und der dmL. Statistisch signifikante Unterschiede zwischen Frauen und Männern fanden sich weder für das Alter der Patienten, den Grad der Einengung des N. medianus, noch der distalen motorischen Latenz des Nervens.
Schlussfolgerung Aus der Verlängerung der distalen motorischen Latenz des N. medianus bei Karpaltunnelsyndrom lässt sich nicht auf den Grad der Einengung des Nervens im Karpalkanal schließen. Mit höherem Patientenalter findet sich die distale motorische Latenz des N. medianus bei KTS stärker verlängert.

Background The majority of patients with symptomatic sterile walled-off necrosis (WON) can be treated conservatively. Although endoscopic transluminal drainage (ETD) is often performed in cases of persistent symptoms, post-procedural iatrogenic infection may occur. This study aimed to evaluate clinical outcomes after ETD of symptomatic sterile WON.
Methods This was a retrospective, multicenter, open-label case series of 56 patients with necrotizing pancreatitis who underwent ETD for symptomatic sterile WON between July 2001 and August 2018 at two tertiary referral hospitals. Primary end point was clinically relevant post-procedural iatrogenic infection, defined as need for endoscopic transluminal necrosectomy. Secondary end points included mortality, total number of interventions, hospital stay, and resolution of symptoms at 1-year follow-up.
Results ETD of sterile WON was performed in 56 patients (median age 55 years, 57 % male), who presented with abdominal pain (71 %), gastric outlet obstruction (45 %), jaundice (20 %), and failure to thrive (27 %). A total of 41 patients (73 %) developed clinically relevant post-procedural iatrogenic infection, resulting in a median of 3 (interquartile range [IQR] 2 – 4) endoscopic, radiological, and/or surgical interventions. Mortality rate was 2 %. Median total hospital stay was 12 days (IQR 6 – 17). Resolution of symptoms was reported in 40 of 46 patients (87 %) for whom long-term follow-up data were available (median follow-up 13 months, IQR 6 – 29).
Conclusions ETD of symptomatic sterile WON resulted in high clinical success. Nonetheless, the majority of patients required additional reinterventions for clinically relevant post-procedural iatrogenic infection.

Abstract
Opioid use is a major problem in India and has high morbidity and mortality with a prevalence of 2.06%. There is a huge treatment gap for opioid use disorders (OUDs). Due to limited mental health resources and limited psychiatric training of medical practitioners in OUDs, a significant proportion of patients do not receive appropriate medical intervention. This article demonstrates how a primary care doctor working in a remote opioid substitution therapy (OST) clinic received assistance from the optional opioid module of clinical schedule for primary care psychiatry (CSP) and collaborative video consultation (CVC) module to address specific difficulties of patients already on Buprenorphine OST and improve the quality of care, thereby reducing chances of relapses. CVC module is a part of one-year digitally driven primary care psychiatry program designed by National Institute of Mental Health and Neurosciences (NIMHANS), Bengaluru. The opioid module was designed by NIMHANS, Bengaluru in collaboration with the All India Institute of Medical Sciences (AIIMS), New Delhi These observations warrant replication of this approach across diverse settings and at a larger scale to explore and evaluate its impact and effectiveness.
Joint patronage in translating Chinese literature into English
Authors: Bai Liping 
Published: June 2020

Abstract
There has been a change in the form of patronage in translating Chinese culture/literature into English since the 1990s,
that is, from sole patronage to joint patronage. This article discusses joint patronage in translating Chinese literature from Chinese into
English through the case of the Chinese Literature Overseas Dissemination Project (中國文學海外傳播工程), which is under the joint patronage of Beijing Normal University, the Confucius Institute at University of
Oklahoma, and the University of Oklahoma Press. The goals of this project have been well achieved with the successful launch of the journal
Chinese Literature Today (CLT) and the publication of the CLT book series. The success of this project demonstrates that joint patronage is
an ideal form of translating Chinese literature into English, and the Chinese Literature Overseas Dissemination Project has
set a good example for the introduction of Chinese literature to the Western world.
Reframing news by different agencies
Authors: Zeng Weixin 
Published: June 2020

Abstract
This study aims to investigate how news reports are reframed and how a stance is in turn mediated in the process of translation by news agencies in the Chinese mainland and Taiwan when they cover the same news event. A database is built from 50 reports on the US-China trade dispute, half from Reference News (RN), a news agency based in Chinese mainland and the other half from Liberty Times (LT), a media outlet in Chinese Taiwan, as well as their corresponding source texts from foreign news agencies. The results show that the reframing practices in the two agencies vary from each other in framing the US-China trade dispute and the image of China and America. The overall pattern of stance shift in the translation by RN is towards a pro-China/anti-US direction while in the translation by LT towards a more anti-China/pro-US direction. These might be caused by the political stance of the news agency, the media environment and the relationship with the United States.
The construction of a Practice-Teaching-Research (PTR) model for the accomplishments of college interpreting teachers in
China
Authors: Kang Zhifeng , Shi Ying 
Published: June 2020

Abstract
This article focuses on the issues of unclear self-positioning, vague objectives and unbalanced factors among the
interpreting practice (IP), interpreting teaching (IT) and interpreting research (IR) of interpreting teachers in Chinese colleges. Based on
the research thread of diachronic and synchronic development in the accomplishments of college interpreting teachers’ in China, and the
approach to analysing the three dimensions of practice, teaching and research, this study investigates interpreting teachers at five
universities in Shanghai. Based on the investigation in Shanghai, this study puts forward a Practice-Teaching-Research (PTR) model as
a three-in-one approach to cultivating comprehensive interpreting teachers’ positioning and strategies in the transition period. It
constructs Overall Interpreting (OI) = Interpreting Practice (IP) + Interpreting Teaching (IT) + Interpreting Research (IR), OI=IP+IT+IR as
the formula, which is the realization of constructing a PTR model as a three-in-one approach for college interpreting teachers in China.
This study has a certain guiding significance in the new era for setting up college interpreting teacher teams and improving their
accomplishments in China.
Sparse dynamic tomography: a shearlet-based approach for iodine perfusion in plant stems
Authors: Bubba Tatiana A , Heikkilä Tommi , Help Hanna , Huotari Simo , Salmon Yann , Siltanen Samuli 
Published: June 2020

Abstract
In this paper we propose a motion-aware variational approach to reconstruct moving objects from sparse dynamic data. The motivation of this work stems from x-ray imaging of plants perfused with a liquid contrast agent, aimed at increasing the contrast of the images and studying the phloem transport in plants over time. The key idea of our approach is to deploy 3D shearlets as a space-temporal prior, treating time as the third dimension. The rationale behind this model is that a continuous evolution of a cartoon-like object is well suited for the use of 3D shearlets. We provide a basic mathematical analysis of the variational model for the image reconstruction. The numerical minimization is carried out with primal-dual scheme coupled with an automated choice of the regularization parameter. We test our model on different measurement setups: a simulated phantom especially designed to resemble a plant stem, with spreading points to simulate a spreading contrast agent; a measured agarose gel phantom to demonstrate iodide diffusion and geometry prior to imaging living sample; a measured living tree grown in vitro and perfused with a liquid sugar–iodine-mix. The results, compared against a 2D static model, show that our approach provides reconstructions that capture well the time dynamic of the contrast agent onset and are encouraging to develop microCT as a tool to study phloem transport using iodine tracer.
Composition dependence of the superconducting properties of UTe2
Authors: Cairns Luke Pritchard , Stevens Callum R , O’Neill Christopher D , Huxley Andrew 
Published: June 2020

Abstract
A better understanding of the synthesis conditions, composition and physical properties of UTe2 are required to interpret previously reported unconventional superconductivity. Here we report how the superconducting properties of single crystals depend on the ratio of elements present in their synthesis by chemical vapour transport. We have obtained crystals with the highest reported ambient pressure T
c and a larger superconducting heat capacity jump from a growth with a U:Te ratio different from that widely used in the literature. For these crystals, the ratio of residual heat capacity in the superconducting state to that of the normal state, γ*/γ
N, is significantly lower than 0.5, reported elsewhere. An upturn in the heat capacity below 200 mK is also reduced compared to other studies and is well described by a Schottky anomaly and residual Sommerfeld term rather than quantum critical behaviour.
