Aims. We present the first three-dimensional internal motions for individual stars in the Draco dwarf spheroidal galaxy.
Methods. By combining first-epoch Hubble Space Telescope observations and second-epoch Gaia Data Release 2 positions, we measured the proper motions of 149 sources in the direction of Draco. We determined the line-of-sight velocities for a sub-sample of 81 red giant branch stars using medium resolution spectra acquired with the DEIMOS spectrograph at the Keck II telescope. Altogether, this resulted in a final sample of 45 Draco members with high-precision and accurate 3D motions, which we present as a table in this paper.
Results. Based on this high-quality dataset, we determined the velocity dispersions at a projected distance of ∼120 pc from the centre of Draco to be σR = 11.0−1.5+2.1 km s−1, σT = 9.9−3.1+2.3 km s−1 and σLOS = 9.0−1.1+1.1 km s−1 in the projected radial, tangential, and line-of-sight directions. This results in a velocity anisotropy β = 0.25−1.38+0.47 at r ≳ 120 pc. Tighter constraints may be obtained using the spherical Jeans equations and assuming constant anisotropy and Navarro-Frenk-White (NFW) mass profiles, also based on the assumption that the 3D velocity dispersion should be lower than ≈1/3 of the escape velocity of the system. In this case, we constrain the maximum circular velocity Vmax of Draco to be in the range of 10.2−17.0 km s−1. The corresponding mass range is in good agreement with previous estimates based on line-of-sight velocities only.
Conclusions. Our Jeans modelling supports the case for a cuspy dark matter profile in this galaxy. Firmer conclusions may be drawn by applying more sophisticated models to this dataset and with new datasets from upcoming Gaia releases.

Context.Comet 8P/Tuttle is a nearly isotropic comet whose physical properties are poorly known and might be different from those of ecliptic comets owing to their different origin. Two independent observations have shown that 8P/Tuttle has a bilobate nucleus.Aims.Our goal is to determine the physical properties of the nucleus (size, shape, thermal inertia, and albedo) and coma (water and dust) of 8P/Tuttle.Methods.We observed the inner coma of 8P/Tuttle with the infrared spectrograph and the infrared camera of theSpitzerSpace Telescope. We obtained one spectrum (5–40μm) on 2 November 2007 and a set of 19 images at 24μm on 22–23 June 2008 sampling the rotational period of the nucleus. The data were interpreted using thermal models for the nucleus and the dust coma, and we considered two possible shape models of the nucleus derived fromHubbleSpace Telescope visible and Arecibo radar observations.Results.We favor a model for the nucleus shape that is composed of two contact spheres with respective radii of 2.7 ± 0.1 km and 1.1 ± 0.1 km and a pole orientation with RA = 285 ± 12° and Dec = +20 ± 5°. The thermal inertia of the nucleus lies in the range 0–100 J K−1m−2s−1∕2and theR-band geometric albedo is 0.042 ± 0.008. The water production rate amounts to 1.1 ± 0.2 × 1028molecules s−1at 1.6 AU from the Sun pre-perihelion, which corresponds to an active fraction of ≈9%. At the same distance, theɛfρquantity amounts to 310 ± 34 cm, and it reaches 325 ± 36 cm at 2.2 AU post-perihelion. The dust grain temperature is estimated to be 258 ± 10 K, which is 37 K higher than the thermal equilibrium temperature at 1.6 AU. This indicates that the dust grains that contribute to the thermal infrared flux have a typical size of ≈10μm. The dust spectrum exhibits broad emission around 10μm (1.5σconfidence level) and 18μm (5σconfidence level) that we attribute to amorphous pyroxene.

Aims. NGC 6240 is a well-studied nearby galaxy system in the process of merging. Based on optical, X-ray, and radio observations, it is thought to harbor two active nuclei. We carried out a detailed optical 3D spectroscopic study to investigate the inner region of this system in connection with existing MERLIN and VLBA data.
Methods. We observed NGC 6240 with very high spatial resolution using the MUSE instrument in the Narrow-Field Mode with the four-laser GALACSI adaptive optics system on the ESO VLT under seeing conditions of 0″.49. Our 3D spectra cover the wavelength range from 4725 to 9350 Å at a spatial resolution of ∼75 mas.
Results. We report the discovery of three nuclei in the final state of merging within a region of only 1 kpc in the NGC 6240 system. Thanks to MUSE we are able to show that the formerly unresolved southern component actually consists of two distinct nuclei separated by only 198 pc. In combination with Gaia data we reach an absolute positional accuracy of only 30 mas that is essential to compare optical spectra with MERLIN and VLBA radio positions.
Conclusions. The verification and detailed study of a system with three nuclei, two of which are active and each with a mass in excess of 9 × 107 M⊙, is of great importance for the understanding of hierarchical galaxy formation via merging processes since multiple mergers lead to a faster evolution of massive galaxies in comparison to binary mergers. So far it has been suggested that the formation of galactic nuclei with multiple supermassive black holes (SMBHs) is expected to be rare in the local universe. Triple massive black hole systems might be of fundamental importance for the coalescence of massive black hole binaries in less than a Hubble time leading to the loudest sources of gravitational waves in the millihertz regime.

Zusammenfassung
Hintergrund Opioidabhängige sind häufig von psychischen Komorbiditäten, insbesondere affektiven Störungen wie Depressionen betroffen. Die Diagnostik und Behandlung von depressiven Störungen in der Substitutionsbehandlung Opioidabhängiger stellen eine besondere Herausforderung dar. Dabei besteht die Gefahr, dass ein Teil der Patienten mit depressiven Symptomen unterversorgt bleibt.
Ziel Die Studie untersucht das Ausmaß depressiver Symptome bei opioidabhängigen Patienten in einer Substitutionsbehandlung und prüft die Übereinstimmung von Selbst- und Fremdbeurteilungen durch den Patienten und den jeweiligen substituierenden Arzt.
Methoden Zeitgleiche Fragebogenerhebung in 6 substituierenden Einrichtungen in Hamburg, Bremen und Kassel. Die Selbstbeurteilung zum Ausmaß von depressiven Symptomen erfolgte bei den Patienten mittels Beck Depressionsinventar (BDI-II). Zeitgleich wurden die substituierenden Ärzte anhand der Hamilton Depressions-Skala (HAMD) zur Beurteilung der depressiven Symptombelastung ihrer Patienten befragt.
Ergebnisse Opioidabhängige Patienten in Substitutionstherapie sind häufig in einem klinisch relevanten Ausmaß von depressiven Symptomen betroffen. Es konnte ein positiver Zusammenhang zwischen den Instrumenten in 4 kategorialen Ausprägungen bestätigt werden. Im Vergleich zur Selbstbeurteilung schätzten die Ärzte die depressive Belastung ihrer Patienten als weniger schwer ein.
Schlussfolgerung Die beiden verwendeten Instrumente sind geeignet, die Diagnostik von depressiven Symptomen bei Opioidabhängigen in Substitutionstherapie zu unterstützen, wobei die Fremdbeurteilung durch die substituierenden Ärzte zurückhaltender ausfällt. Die Studienergebnisse verweisen auf die hohe Relevanz der Diagnostik depressiver Symptomatik unter Opioid-Substituierten, um ggf. geeignete Behandlungsmaßnahmen einzuleiten.
The role of metaphor in categorization
Authors: Gong Yumiao , Zhou Rong 
Published: November 2019

This study is concerned with the processing of metaphor in real time for the purpose of elucidating metaphor categorization. We distinguish between attributive metaphors such as the surface of the lake is a mirror, in which the attributes of a lake are likened to those of a mirror, and conceptually complex relational metaphors like history is a mirror, which exhibit a structural resemblance between the topic history and the metaphorical vehicle mirror. We conducted an experiment that provided evidence that for attributive metaphors only literal meanings of the vehicle are activated, while in relational metaphors they are activated only for 300 ms, but then actively suppressed. Our experimental data suggest that, for relational metaphors, structure-mapping and schema induction underlie metaphorical categorization.
Linguistic and mental representations of caused motion in Chinese and English children
Authors: Ji Yinglin 
Published: November 2019

This study examines (non)linguistic representations of caused motion by Chinese and English children in two cartoon-based experiments. Findings of the language production task reveal that typological properties influence the semantic density of children’s utterances. Regardless of age, children express denser semantic information in Chinese than in English. In the non-linguistic match-to-sample task, children of 3 years are found to be predominantly path-oriented, as evidenced by their significantly longer fixation on path-match (rather than manner-match) videos. The analysis of reaction time indicates that children of 8 years and adults show significant variations in spatial cognition that can be related to linguistic differences: English speakers tend to be more manner-oriented while Chinese speakers are equally manner- and path-oriented.

Published: November 2019

Abstract
Health, safety and injury prevention actions should be prioritized in aquaculture, where workers are exposed to a wide range of risks. This paper is based on a scoping report by a group of international experts, funded by the Food and Agriculture Organization (FAO) and administered by Fisheries and Aquaculture Workers Network of the International Union of Food, Agricultural, Hotel, Restaurant, Catering, Tobacco and Allied Workers' Associations (IUF). Relevant literature was reviewed and the study drew on an international workshop to develop templates and related for regional and national aquaculture occupational safety and health (AOSH) profiles. The literature review included Scielo and Google Scholar databases as well as Google and Brazilian government websites. The searches included material in Portuguese, English and Spanish. The results reported here give an overview of Brazilian AOSH and hazards and cover Brazilian and relevant international worker health and safety laws and organization applicable to the particular hazards in aquaculture. There is a special emphasis on the position of children and women workers linked to the wider social organization of work and welfare, and finally the challenges to and possibilities for good AOSH. Despite major developments in aquaculture production, much still needs to be improved to ensure the safety and health of workers in the sector.

Published: November 2019

AbstractThis study aimed to determine the optimal accelerometer wear‐site specific cut‐points for discrimination of the sedentary time, light physical activity and moderate‐to‐vigorous physical activity (MVPA) in older adults. Twenty‐three adults (14 females) aged 55–77 years wore a GENEActiv accelerometer on their non‐dominant wrist, dominant wrist, waist and dominant ankle whilst undertaking eight, five‐minute bouts of activity: lay supine, seated reading, slow walking, medium walking, fast walking, folding laundry, sweeping and stationary cycling. VO2 was assessed concurrently using indirect calorimetry. Receiver‐operating‐characteristic (ROC) analyses were used to derive wear‐site specific cut‐points for classifying intensity. Indirect calorimetry indicated that being lay supine and seated reading were classified as sedentary (<1.5 METs), laundry as light (1.51–2.99 METs) and sweeping, slow, medium and fast walking and cycling all classified as moderate intensity (>3 METs). Areas under ROC curves indicated that the classification of sedentary activity was good for the non‐dominant wrist and excellent for all other wear sites. Classification of MVPA was excellent for the waist and ankle, good for the waist and poor for the dominant and non‐dominant wrists. Overall, the ankle location performed better than in other locations. Ankle‐worn accelerometry appears to provide the most suitable wear‐site to discriminate between sedentary time and MVPA in older adults.

Published: November 2019

Abstract
This paper addresses the improved science resulting from joint observations performed by the different instruments onboard the Advanced Space-based Solar Observatory (ASO-S) mission along with ancillary instruments on missions flying at the same time. It first describes the three major instruments along with their stated objectives. Then it presents some basic science issues concerning jointly observed flares, coronal mass ejections (CMEs) and eruptive prominences (EPs). Each physical candidate (magnetic reconnection, instability, hard X-ray emission and magnetic coronal field topology) is discussed in terms of its signature and identification with ASO-S instrumentation. The importance of Lyα detection and non-LTE modeling is stressed. Some instrumental and science challenges are briefly discussed.

Published: November 2019

Abstract
In the area presence of remnants of a historical Speelwijk castle friary built in 1681 – 1684 and in 1780 the inside building ruined. It different if we see from map Speelwijk castle around earlier years when the inside of the building is still there. To see the traces of the building we used geophysical methods i.e GPR. GPR survey using mostly a 600 MHz frequency antenna to get high-resolution and low penetration. GPR works by sending a tiny pulse of energy into a material via antenna. Subsurface variations create reflections that are picked up by the material content. GPR can provide high resolution imaging of shallow subsurface targets based on changes in the electromagnetic properties of the material. The visualization data GPR will image two dimensional (2D) where we can see the depth from anomalies body. The 2D view allows the enhanced targets to an identification of potential archaeological object buried.

Published: November 2019

Abstract
Mach Zehnder interferometer (MZI) based on plastic optical fiber (POF) is interesting due to its robustness and simple fabrication. In this work, MZI-POF was designed and its sensitivity to temperature change was characterized to investigate its performance for sensor application. The MZI-POF was fabricated by forming two tapers at several distance by simple heat-pull method. The spectra was investigated by launching white light emitting diode (LED) and the output were observed using VIS-NIR spectrometer. It is shown that the wavelength of spectrum peak and spectrum dip were shifted compared to that of un-tapered POF which indicates that the structure serves well as MZI. Sensor sensitivity to temperature was determined by measuring the spectrum for various temperature which was varied from 40°C to 80°C with increment of 5°C. The result showed that the sensor sensitivity is 0.0693nm/°C in terms of peak measurement and 0.0487nm/°C for dip measurement. Therefore, MZI-POF is a potential candidate for temperature sensor.

Authors: Chairunisa W , Imawan C 
Published: November 2019

Abstract
The effect of the pH on the color change characteristics of the methyl red solution, when exposed by gamma radiation, is the main objective of this study. The colorwas characterized using a UV-Visible spectrophotometer and a digital photography camera. The used irradiator source is 60Co with doses varied from 5-100 kGy and a dose rate of 5.5 kGy/h. The color stability was studied by observing the effects of the storage conditions of the solution: temperature, light, and humidity. The original methyl red solution at pH 6.3 has a red color and gives a radiochromic phenomenon with a change of color from red to dark red for a dose of 5-20 kGy, then the color fades and turns colorless gradually at a dose of 25-100 kGy. On the other hand, for a methyl red solution of pH 7.1 before irradiation has a yellow color, turns to dark yellow at doses of 5-25 kGy, then the color fades and becomes colorless at a dose 40 kGy. The color of the methyl red solution at pH 7.1 is more stable against storage light conditions compared to pH 6.3. These results suggest that this methyl red solution can be used as a gamma-ray dosimeter in the dose range of 5-40 kGy.
