Published: March 2021

Abstract
Recent years have seen the development of display technology with the transformation from flat to flexible displays. This has led to changes in the typical shape of such displays, and curved displays with constant curvature have been developed recently. As the shape of the display changes, the sophistication of the lamination process for joining a flat and curved window cover glass with a panel substrate also increases, and continuous research and development is required. In this paper, we report the results of our study on the characteristics of resin spreading on flat and curved substrates using optical clear resin. We confirmed the consistency by comparing the results obtained from the theoretical analysis and experiments. These results are expected to be widely used in the lamination and manufacturing technologies for next-generation displays that will evolve in the future.

Penelitian ini bertujuan untuk mengetahui berapa besar pengaruh variable saluran distribusi (X1), biaya pemasaran (X2) dan volume penjulan (X3) terhadap pendapatan petani kentan (Y). Dan tujuan berikutnya adalah untuk mengetahui saluran distribusi pemasaran yang paling efisien dari petani hingga ke konsumen akhir. Metode penelitian yang digunakan adalah metode survey dengan menggunakan 143 responden petani kentan yang ada dilokasi peneklitian. Hasil penelitian menunjukkan bahwa variable biaya pemasaran (X2) kurang berpengaruh terhadap tingkat pendapatan petani kentan sedangkan hipotesi yang dikemukakan berpengaruh. Adanya temuan yang berbeda dengan hasil uji statika (uji t), dimana biaya pemasaran kurang berpengaruh dibanding variable X1 dan X3, karena pedagang perantara langsung ke lokasi petani sehingga kurang mengeluarkan biaya pemasaran dan secara lagsung mempengaruhi tingkat pedapatan petani. Saluran distribusi yang paling efisien berdasarkan uji formulasi efsiensi pemasaran adalah pada saluran pemasaran yang IV ( dari produsen- pedagang perantara- konsumen = 21,39 ) .Teknik pengambilan sampel menggunakan teknik simple jenuh. Hasil penelitian menunjukan bahwa saluran pemasaran merupakan variable dominan yang mempengaruhi tingkat pedapatan petani kentan di Kecamatan Tombolo Pao sebesar 0,586 dan disusul pada variable volume penjualan sebesar 0,249.
This study aims to determine how much the influence of the distribution channel variable (X1), marketing costs (X2) and sales volume (X3) on the income of potato farmers (Y). The next goal is to find out the most efficient marketing distribution channel from farmers to the consumers. The research method used was a survey method using 143 respondents of potato farmers who were in the research location. The results show that the marketing cost variable (X2) has less effect on the income level of potato farmers, while the hypothesis stated it has an effect. There are findings that are different from the results of the statistical test (t test), where marketing costs are less influential than variables X1 and X3, because the intermediary traders go directly to the location of the farmers so that they spend less marketing costs and directly affect the level of farmers’ income. The most efficient distribution channel based on the marketing efficiency formulation test is the IV marketing channel (from producer-trader to intermediary-consumer = 21.39). The sampling technique uses saturated simple technique. The results showed that the marketing channel is the dominant variable that affects the income level of potato farmers in the District of Tapio Pao by 0.586 and followed by the variable sales volume of 0.249.

Action affects perception through modulation of attention

Published: March 2021

AbstractThe present study explored the origin of perceptual changes repeatedly observed in the context of actions. In Experiment 1, participants tried to hit a circular target with a stylus movement under restricted feedback conditions. We measured the perception of target size during action planning and observed larger estimates for larger movement distances. In Experiment 2, we then tested the hypothesis that this action specific influence on perception is due to changes in the allocation of spatial attention. For this purpose, we replaced the hitting task by conditions of focused and distributed attention and measured the perception of the former target stimulus. The results revealed changes in the perceived stimulus size very similar to those observed in Experiment 1. These results indicate that action’s effects on perception root in changes of spatial attention.
“She finds you abhorrent” - The impact of emotional context information on the cortical processing of neutral faces in depression

AbstractDepression is associated with abnormalities in patterns of information processing, particularly in the context of processing of interpersonal information. The present study was designed to investigate the differences in depressive individuals in cortical processing of facial stimuli when neutral faces were presented in a context that involved information about emotional valence as well as self-reference. In 21 depressive patients and 20 healthy controls, event-related potentials (ERPs) were recorded during the presentation of neutral facial expressions, which were accompanied by affective context information that was either self- or other-related. Across conditions, depressive patients showed larger mean P100 amplitudes than healthy controls. Furthermore, mean late positive potential (LPP) amplitudes of depressive patients were larger in response to faces in self-related than in other-related context. In addition, irrespective of self-reference, mean LPP responses of depressive patients to faces presented after socially threatening sentences were larger compared with faces presented after neutral sentences. Results regarding self-reference supported results of previous studies indicating larger mean amplitudes in self-related conditions. Findings suggest a general heightened initial responsiveness to emotional cues and a sustained emotion processing of socially threatening information in depressive patients.
Stellar Collapse Diversity and the Diffuse Supernova Neutrino Background
Authors: Kresse Daniel , Ertl Thomas , Janka Hans-Thomas 
Published: March 2021

Abstract
The diffuse cosmic supernova neutrino background (DSNB) is an observational target of the gadolinium-loaded Super-Kamiokande (SK) detector and the forthcoming JUNO and Hyper-Kamiokande detectors. Current predictions are hampered by our still incomplete understanding of the supernova (SN) explosion mechanism and of the neutron star (NS) equation of state and maximum mass. In our comprehensive study we revisit this problem on grounds of the landscapes of successful and failed SN explosions obtained by Sukhbold et al. and Ertl et al. with parameterized one-dimensional neutrino engines for large sets of single-star and helium-star progenitors, with the latter serving as a proxy for binary evolution effects. Besides considering engines of different strengths, leading to different fractions of failed SNe with black hole (BH) formation, we also vary the NS mass limit and the spectral shape of the neutrino emission and include contributions from poorly understood alternative NS formation channels, such as accretion-induced and merger-induced collapse events. Since the neutrino signals of our large model sets are approximate, we calibrate the associated degrees of freedom by using state-of-the-art simulations of proto-NS cooling. Our predictions are higher than other recent ones because of a large fraction of failed SNe with long delay to BH formation. Our best-guess model predicts a DSNB

-flux of

cm−2 s−1 with

cm−2 s−1 in the favorable measurement interval of [10, 30] MeV and

cm−2 s−1 with

energies > 17.3 MeV, which is roughly a factor of two below the current SK limit. The uncertainty range is dominated by the still insufficiently constrained cosmic rate of stellar core-collapse events.
A Jet-bases Emission Model of the EHT2017 Image of M87*

Published: March 2021

Abstract
We carry out general relativistic ray-tracing radiative-transfer calculations to study whether a localized emission from plasma rings created at the stagnation surface in the jet funnel, to which we refer as stagnation rings, can explain the ring image of M87* observed by the Event Horizon Telescope (EHT) 2017. The resultant images consist of the direct image of the stagnation rings and the ring images formed via the strong deflection by the black hole (BH) gravity, to which we refer as quasi photon-ring. For the model with the BH spin a
* = 0.99, the direct image of the counter-jet and quasi photon-ring are almost coincident to the photon ring with diameter ∼ 40 μas, while the approaching jet shows the small ring image inside them. The synthetic observation image assumes that the EHT2017 array is consistent with that observed in M87*, because the array is a bit sparse to detect the inner ring image. This indicates that the ring image in M87* may contain the important feature of the jet bases in addition to the photon ring. We find that forthcoming EHT observations can resolve the stagnation ring image and may enable us to explore the plasma-injection mechanism in the jet funnel.

Abstract
The Maunder Minimum (1645–1715; hereafter MM) is generally considered as the only grand minimum in the chronological coverage of telescopic sunspot observations. Characterized by scarce sunspot occurrences and their asymmetric concentrations in the southern solar hemisphere, the MM has frequently been associated with a special state of solar dynamo activity. As such, it is important to analyze contemporary observational records and improve our understanding of this peculiar interval, whereas the original records are frequently preserved in historical archives and can be difficult to access. In this study, we consult historical archives in the National Library of Russia, St. Petersburg, and analyze a series of sunspot observations conducted at the Eimmart Observatory from 1681 to 1709, which is the second-richest sunspot data set produced during the MM, following La Hire's series, among existing data sets. We have further extended our analyses to neighboring observations to extend our investigations up to 1718. We first analyze source documents and descriptions of observational instruments. Our analyses have significantly revised the existing data set, removed contaminations, and updated and labeled them as Eimmart Observatory (78 days), Altdorf Observatory (4 days), Hoffmann (22 days), and Wideburg (25 days). The revisions have updated the temporal coverage of the contemporary sunspot observations from 73.4% to 66.9% from 1677 to 1709. We have also derived the positions of the observed sunspot groups in comparison with contemporary observations. Our results indicate hemispheric asymmetry in the MM and recovery of sunspot groups in both hemispheres after 1716, supporting the common paradigm of the MM.

Abstract
We present the results of a detailed investigation of the poorly studied X-ray pulsar (XRP) XTE J1858+034 based on the data obtained with the NuSTAR observatory during the outburst of the source in 2019. The spectral analysis resulted in the discovery of a cyclotron absorption feature in the source spectrum at ∼48 keV in both the pulse phase-averaged and resolved spectra. Accurate X-ray localization of the source using the NuSTAR and Chandra observatories allowed us to accurately determine the position of the X-ray source and identify the optical companion of the pulsar. The analysis of the counterpart properties suggested that the system is likely a symbiotic binary hosting an XRP and a late-type companion star of the K-M classes rather than a Be X-ray binary as previously suggested.
Spectroscopic Monitoring of the Candidate Tidal Disruption Event in F01004–2237

Published: March 2021

Abstract
We present results of spectroscopic monitoring observations of the ultraluminous infrared galaxy F01004−2237. This galaxy was observed to undergo changes in its optical spectrum, detected by comparing a spectrum from 2015 with one from 2000. These changes were coincident with photometric brightening. The main changes detected in the optical spectrum are enhanced He ii
λ4686 emission and the appearance of He i
λ3898,λ5876 emission lines. The favored interpretation of these changes was that of a tidal disruption event (TDE) happening in 2010. However, subsequent work suggested that these changes are caused by another hitherto unknown effect related to variations in the accretion rate in the active galactic nucleus (AGN). Our optical spectroscopic monitoring observations show that the evolution of the He lines is in line with the evolution seen in TDEs and opposite of what is observed from reverberation-mapping studies of AGNs, renewing the discussion of the interpretation of the flare as a TDE.
Data-driven MHD Simulation of Successive Solar Plasma Eruptions
Authors: Kaneko Takafumi , Park Sung-Hong , Kusano Kanya 
Published: March 2021

Abstract
Solar flares and plasma eruptions are sudden releases of magnetic energy stored in the plasma atmosphere. To understand the physical mechanisms governing their occurrences, three-dimensional magnetic fields from the photosphere up to the corona must be studied. The solar photospheric magnetic fields are observable, whereas the coronal magnetic fields cannot be measured. One method for inferring coronal magnetic fields is performing data-driven simulations, which involves time-series observational data of the photospheric magnetic fields with the bottom boundary of magnetohydrodynamic simulations. We developed a data-driven method in which temporal evolutions of the observational vector magnetic field can be reproduced at the bottom boundary in the simulation by introducing an inverted velocity field. This velocity field is obtained by inversely solving the induction equation and applying an appropriate gauge transformation. Using this method, we performed a data-driven simulation of successive small eruptions observed by the Solar Dynamics Observatory and the Solar Magnetic Activity Telescope in 2017 November. The simulation well reproduced the converging motion between opposite-polarity magnetic patches, demonstrating successive formation and eruptions of helical flux ropes.

A total of 96 species of lichens taxa belonging to 45 genera and 20 families are enumerated from Similipal Biosphere Reserve, in Mayurbhanj district as an addition to the lichen biota of Odisha, India. Most of the crustose lichen taxa usually growing as epiphytes on different phorophytes of the biosphere reserve exhibit their dominance. Among crustose lichens the members of family Graphidaceae with 26 species of 14 genera shown their maximum dominance. Together with Graphidaceae the lichen genus Pyrenula represented by 15 species found growing luxuriantly on smooth barked trees of the biosphere reserve. The dominant trees in the biosphere such as Shorea robusta Gaertn. followed by Mangifera indica L., Simarouba glauca DC. and Madhuca longifolia (L.) J. F. Macbr., provided suitable habitat for a number of lichen taxa to colonize. The south-west (SW) region of Similipal Biosphere Reserve exhibits the maximum additions of lichens, followed by north-west (NW), north-east (NE) and south-east (SE) respectively.
Sponge-dwelling fauna: a review of known species from the Northwest Tropical Atlantic coral reefs

Published: March 2021

Within tropical shallow-water coral reefs, marine sponges provide microhabitats for a wide range of fauna. Although there have been numerous studies and reports of symbiotic relationships amongst sponges and their associated fauna, those pieces of information are isolated and disconnected. For this reason, based on the available literature, we compiled a species-interaction dataset of coral reef marine sponge-associated fauna known to date.
We introduce a dataset that includes 67 literature items that report 101 species of sponge hosts clustered in 12 Orders having a host/guest interaction with 284 guest species from six Phyla present in the Northwestern Tropical Atlantic coral reefs. This dataset consists of two types of information: 1. Machine-readable data and 2. Human-readable data. These two types of coding improve the scope of the dataset and facilitate the link between machine platforms and human-friendly displays. We also created an interactive visualisation of the species-interactions dataset and of a dynamic Chord Diagram of the host-guest species connections to generate a user-friendly link between the user and the dataset.

Alors qu’il devrait être une force (Cummins, 1976, 2001), le bilinguisme des élèves immigrés semble plutôt constituer une faiblesse sur le plan scolaire, même sous contrôle du niveau socio-économique des élèves (Jacobs et Rea, 2011). À la suite de plusieurs projets de valorisation des langues et cultures d’origine à travers le monde (Hirst et al. , 2010 ; Hope, 2011 ; Iddings, 2009 ; Masny, 2008), nous avons mis en œuvre un dispositif expérimental qui consiste à donner aux parents d’élèves allophones de deuxième année primaire la traduction en langue maternelle des textes travaillés en classe. Sur la base d’une quantification des moments de lecture à domicile offerts par les parents à leur enfant via des questionnaires, cette recherche montre que proposer ces textes bilingues aux parents d’élèves allophones, faire un premier pas vers eux, a un effet positif sur l’engagement de ces parents.
