description: The distribution of magnetic fields of positive and negative polarities over the surface of the Sun was studied on the basis of synoptic maps presented by the NSO/Kitt Peak (1978-2016). To emphasize the contribution of weak fields the following transformation of synoptic maps was made: for each synoptic map only magnetic fields with modulus less than 5G ($|B|\leq 5$G) were left unchanged while larger or smaller fields were replaced by the corresponding threshold values +5G or $-5$G. Cyclic variations of the magnetic field polarity have been observed associated with two types of magnetic field flows in the photosphere. Rush-to-the-Poles (RTTP) appear near the maximum of solar activity and have the same sign as the following sunspots. The lifetime of RTTP is $\sim 3$ yrs, during which time they drift from latitudes $30^\circ$-$40^\circ$ to the pole, causing the polarity change of the Sun's polar field. Our aim is the study of another type of variations which has the form of series of flows with individual flows of 0.5-1 yr with alternating polarity. These flows called ripples are located in time between two RTTP and drift from the equator to the latitudes of $~50^\circ$. The period of variation of ripples was shown to be 1.1 yr for the northern hemisphere and 1.3 yr for the southern hemisphere. It was found that the amplitude of variation was higher for the time intervals where the polar field had a positive sign. Within the same flow, fields of positive and negative signs developed in anti-phase. Two types of flows - RTTP and ripples - together formed a unique structure which had close connection to the magnetic solar cycle.

description: We present the first results on the new black hole candidate, MAXI J1305-704, observed by MAXI/GSC. The new X-ray transient, named as MAXI J1305-704, was first detected by the MAXI-GSC all-sky survey on 2012 April 9 in the direction to the outer Galactic bulge at (l,b)=(304.2deg,-7.6deg). The Swift/XRT follow-up observation confirmed the uncatalogued point source and localized to the position at (13h06m56s.44,-70d27'4".91). The source continued the activity for about five months until 2012 August. The MAXI/GSC light curve in the 2--10 keV band and the variation of the hardness ratio of the 4-10 keV to the 2-4 keV flux revealed the hard-to-soft state transition on the the sixth day (April 15) in the brightening phase and the soft-to-hard transition on the ~60th day (June 15) in the decay phase. The luminosity at the initial hard-to-soft transition was significantly higher than that at the soft-to-hard transition in the decay phase. The X-ray spectra in the hard state are represented by a single power-law model with a photon index of ~2.0, while those in the soft state need such an additional soft component as represented by a multi-color disk blackbody emission with an inner disk temperature ~0.5--1.2 keV. All the obtained features support the source identification of a Galactic black-hole binary located in the Galactic bulge.

Fault structure and mechanics of the Hayward Fault, California, from double-difference earthquake locations

description: The relationship between small-magnitude seismicity and large-scale crustal faulting along the Hayward Fault, California, is investigated using a double-difference (DD) earthquake location algorithm. We used the DD method to determine high-resolution hypocenter locations of the seismicity that occurred between 1967 and 1998. The DD technique incorporates catalog travel time data and relative P and S wave arrival time measurements from waveform cross correlation to solve for the hypocentral separation between events. The relocated seismicity reveals a narrow, near-vertical fault zone at most locations. This zone follows the Hayward Fault along its northern half and then diverges from it to the east near San Leandro, forming the Mission trend. The relocated seismicity is consistent with the idea that slip from the Calaveras Fault is transferred over the Mission trend onto the northern Hayward Fault. The Mission trend is not clearly associated with any mapped active fault as it continues to the south and joins the Calaveras Fault at Calaveras Reservoir. In some locations, discrete structures adjacent to the main trace are seen, features that were previously hidden in the uncertainty of the network locations. The fine structure of the seismicity suggests that the fault surface on the northern Hayward Fault is curved or that the events occur on several substructures. Near San Leandro, where the more westerly striking trend of the Mission seismicity intersects with the surface trace of the (aseismic) southern Hayward Fault, the seismicity remains diffuse after relocation, with strong variation in focal mechanisms between adjacent events indicating a highly fractured zone of deformation. The seismicity is highly organized in space, especially on the northern Hayward Fault, where it forms horizontal, slip-parallel streaks of hypocenters of only a few tens of meters width, bounded by areas almost absent of seismic activity. During the interval from 1984 to 1998, when digital waveforms are available, we find that fewer than 6.5% of the earthquakes can be classified as repeating earthquakes, events that rupture the same fault patch more than one time. These most commonly are located in the shallow creeping part of the fault, or within the streaks at greater depth. The slow repeat rate of 2–3 times within the 15-year observation period for events with magnitudes around M = 1.5 is indicative of a low slip rate or a high stress drop. The absence of microearthquakes over large, contiguous areas of the northern Hayward Fault plane in the depth interval from ∼5 to 10 km and the concentrations of seismicity at these depths suggest that the aseismic regions are either locked or retarded and are storing strain energy for release in future large-magnitude earthquakes.

description: The goal of this research is to find out if violence in children’s films has increased within the past five decades. In order to achieve this goal, 22 children’s films were given multiple reviews by college students, who carefully analyzed them using the same questionnaire. Using a simple random sampling method of research, films were chosen within clusters of decades and were analyzed using variables that depict violence. After collectively studying the results of the twenty-two children’s films, we discovered that violence in children’s films has increased over the past five decades.

description: In the framework of a nonrelativistic potential quark model, we investigate the mass spectrum of the $1S$-wave charmed-strange tetraquark states of $cn\bar{s}\bar{n}$ and $cs\bar{n}\bar{n}$ ($n=u$ or $d$) systems. The tetraquark system is solved by a correlated Gaussian method. With the same parameters fixed by the meson spectra, we obtained the mass spectra for the $1S$-wave tetraquark states. Furthermore, based on the predicted tetraquark spectra we estimate their rearrangement decays in a quark-exchange model. We find that the rearrangement decays of the tetraquarks may be mainly driven by the spin-spin interactions. The resonances $X_0(2900)^0$ and $T^a_{c\bar{s}0}(2900)^{++/0}$ reported from LHCb may be assigned to be the lowest $1S$-wave tetraquark states $\bar{T}_{cs0}^f(2818)$ and $T^{a}_{c\bar{s}0}(2828)$ classified in the quark model, respectively. It also allows us to extract the couplings for the initial tetraquark states to their nearby $S$-wave interaction channels. We find that some of these couplings turn out to be sizeable. Following the picture of the wavefunction renormalization for the near-threshold strong $S$-wave interactions, the sizeable coupling strengths can be regarded as an indication of their dynamic origins as candidates for hadronic molecules. Furthermore, our predictions suggest that signals for the $1S$-wave charmed-strange tetraquark states can also be searched in the other channels, such as $D^0K^+$, $D^+K^+$, $D^{*+}K^-$, $D^{*+}K^+$, $D^{*0}K^+$, $D^0\bar{K}^{*0}$, $D_s^+ρ^0$, etc.

The normative constitution of the European Union and the political project of European integration were rejected by the United Kingdom during its nationalist hour. But ninety seven years ago, Coudenhove-Kalergi's "Pan-Europe" project and book had excluded "Britain", because it "had grown out of Europe". The similarities between "then" and "now" are striking as nationalism collides with the philosophy and vision of democratic cosmopolitanism.
Giant molecular clouds: star factories of the galaxy

description: Stars are forming in our galaxy at a rate of between 1 and 4 solar masses of stars per year. In contrast to elliptical galaxies, which are largely devoid of star formation, star formation is still going on in spiral galaxies because of their reservoirs of molecular gas, the fuel for new stars. The discs of spiral galaxies are comprised not only of stars as we clearly see from Earth, but also gas (the interstellar medium, ISM). This is where this gas accumulates into cold, dense, molecular regions known as molecular clouds, in which new stars are formed. Most star formation occurs in massive molecular clouds, known as giant molecular clouds (GMCs). However, while we have a good understanding of how individual stars form, there is less consensus on how their natal clouds of gas accumulate, how long these clouds last, how star formation progresses over their lifetime, and indeed how star formation has progressed over the lifetime of the Milky Way.

description: The construction of Europe as a driving force for political solidarity between the Member States is the hypothesis that this Special Focus seeks to confront with the reality of the reaction to the COVID-19 crisis in Europe. There certainly is no academic or researcher in any discipline for whom this unprecedented situation does not raise many questions. More importantly, aren't these questions evolving and constantly changing as the health situation itself evolves? The present initiative does not seek to answer these questions prematurely, but to bring European researchers together to address the interrogation that currently unites us and has the humble, but hopefully useful, aim of asking the right questions, for opening up a fertile ground for our future research.

description: We provide a recurrent construction of entanglement witnesses for a bipartite systems living in a Hilbert space corresponding to $2N$ qubits ($N$ qubits in each subsystem). Our construction provides a new method of generalization of the Robertson map that naturally meshes with $2N$ qubit systems, i.e., its structure respects the $2^{2N}$ growth of the state space. We prove that for $N>1$ these witnesses are indecomposable and optimal. As a byproduct we provide a new family of PPT (Positive Partial Transpose) entangled states.

description: It is of course too early to draw conclusions about the European Union's response to the COVID-19 crisis in its Member States while we are still in the midst of the health crisis. On the other hand, it is already possible to correct the widely shared first impression that European solidarity had been shattered. The available public data systematized in Section II and the analyses in Section III show that European solidarity has been expressed in two ways: First, bilaterally between EU Member States; second, collectively under the recent impetus of the European Commission. To help explain this impression of the absence of a Union, Section IV proposes three paths that should be the subject of further research: public information and the policy of transparency of European public action, the Union's emergency-reaction autonomy in the face of third countries' Realpolitik strategies, and the gap between the expectations of the Union's citizens and its actual competences.

description: In 2019, the Court of Justice has ruled in an innovative case on the protection of the independence of Member States' judiciaries. In two judgments, delivered in June and November, the Court declared that several statutes amending the organisation of the Polish judicial system infringed the second subparagraph of Art. 19, para. 1, TEU because they did not respect judicial independence. This case law relies on two key legal arguments: an "ideal" holistic approach to judicial independence and the broadening of the material scope of Art. 19 TEU (see Court of Justice: judgment of 24 June 2019, case C-619/18, Commission v. Poland (Independence of the Supreme Court) [GC]; judgment of 5 November 2019, case C-192/18, Commission v. Poland (Independence of ordinary courts) [GC]). Both arguments may invite us to think that this case law is boundless. This Insight considers if some limits should nevertheless apply.

description: In this study, the Soil and Water Assessment Tool (SWAT) is coupled with the Bacteria Source Load Calculator (BSLC) to develop alternative scenarios of agricultural best management practice (BMP) implementation and septic system repair to achieve total maximum daily load (TMDL) targets for Escherichia coli (E. coli) in a small agricultural watershed located in Michigan, USA. Due to the uncertainty involved in bacterial source estimation from wildlife and failing septic systems in agricultural watersheds, we propose a method for estimating their respective bacteria loading during SWAT calibration, which was performed at eight sampling locations and validated at a ninth. BMP implementation scenarios were prioritized based on their ability to meet TMDL targets at the lowest cost using a spatially targeted subwatershed ranking identifying the greatest E. coli source contribution. BMP effectiveness is driven by E. coli source locations defined in the BSLC-SWAT linkage. The framework developed here, from linking BSLC to SWAT to ranking subwatersheds, was effective in meeting the TMDL targets and is readily transferable to other watersheds. Agricultural BMPs were unsuccessful in meeting TMDL targets, but the target can be met by repairing about 60 of 110 estimated failing septic tanks.

description: Ecosystem services (ES) are fundamental to sustaining life on earth, although they are under pressure due to anthropogenic activities. The aim of this study is to investigate the trend of ES valuation (ESV) associated with land use/land cover (LULC) change. LULC datasets from 1988 to 2018 and the global ESV coefficient were used to conduct the estimation of ESVs and their changes through ArcGIS. The agricultural provisioning ESVs were also collected from the field to compare with the global ESV data. The total ESV decreased from US$481.85 million in 1988 to US$445.5 million in 2018, with a decreasing rate of US$1.21 million per year. Within this period, the largest ESV increment was observed in cultivated land with an increasing of US$33.47 million, and the largest decreasing was observed in grazing land with a decreasing of US$47.35 million. Based on local and global data, the agriculture land ESV were US$8,610.34 and US$1.34 million ha−1 year−1, respectively. This indicates a significance difference between local study and global ESV data. Overall, the decreasing of ESVs indicated that the environment is degrading due to the land conversion and this suggest sustainable development projects as intervention are required.

description: The purpose of this Insight is to illustrate how State aid law will work in this troubled time. First, it focuses on Art. 107, para. 3, let. b) and c), TFEU and the Temporary Framework adopted by the European Commission to support the economy in the context of the COVID-19 outbreak. Furthermore, it clarifies the role that Art. 107, para. 2, let. b), TFEU may play. Finally, it takes into consideration the General Block Exemption Regulation, and the de minimis Regulations. It is argued that a new approach to State aid law will be needed in the coming years, based on a compensation mechanism and some other expedients to avoid competitive distortions.

description: The baryonic mass-to-light ratio used to perform the photometry-to-mass conversion has a tremendous influence on the measurement of the baryonic content and distribution, as well as on the determination of the dark halo parameters. Since numerous clues hint at an inside-out formation process for galaxies, a radius-dependant mass-to-light ratio is needed to physically represent the radially varying stellar population. In this article, we use chemo-spectrophotometric galactic evolution (CSPE) models to determine the mass-to-light ratio for a wide range of masses and sizes in the scenario of an inside-out formation process by gas accretion. We apply our method on a SINGS subsample of ten spiral and dwarf galaxies for stellar bands covering from the UV to the MIR. The CSPE models prove to be a good tool to weight the different photometric bands in order to obtain consistent stellar discs' masses regardless of the spectral band used. On the other hand, we show that colour index vs. the mass-to-light ratio relation is an imperfect tool to assign masses to young stellar populations because of the degeneracy affecting mass-to-light ratio in all bands at low colour index. Resulting discs from our analysis are compatible with the maximum disc hypothesis provided that adequate bulge/disc decomposition is performed and correction for the presence of a bar is not neglected since it disturbs the internal disc kinematics. Disc-mass models including mass-to-light ratio-as a free parameter as well as models using our physically motivated radial variation of mass-to-light ratio are presented and discussed for each galaxy.

ORIGINAL DESCRIPTION: 1848b: 67.
TYPE LOCALITY: “ Brasile [Brazil]” (Rondani 1848b: 63); [Belem (Pará), Brazil] (Papavero 1973: 343). See Remarks.
TYPE MATERIAL: 1 ♀, syntype (covered with mold) (MZUN: Box Coll. entomol. Extra-europea, Fam. Sirfidei - Gen. Aphritis a Phalacromya): Phalacromya submetallica Rnd., Brasile / M. Zool. N° 11216 / ♀.
CURRENT STATUS: valid species, as Copestylum submetallicum (Thompson et al. 1976: 85).
REMARKS: Rondani (1848b: 67) described Phalacromya submetallica from just the female sex, without specifying the exact number of specimens, but giving a single measurement of length, from material collected in South America by V. Ghiliani. Costa (1866: 31) listed a single MZUN specimen numbered “605”. We also found one syntype in this study. Although Rondani (1848b: 63) only gave the type locality as “ Brasile ”, Papavero (1973: 343) gave a more accurate type locality based on a note in Spinola (1853) that said all specimens collected by Ghiliani in 1846 were collected in Belem, Pará, Brazil.

description: Models fail to reproduce observations of the coldest parts of the Sun's atmosphere, where interactions between multiple ionized and neutral species prevent an accurate MHD representation. This paper argues that a meter-scale electrostatic plasma instability develops in these regions and causes heating. We refer to this instability as the Thermal Farley-Buneman instability, or TFBI. Using parameters from a 2.5D radiative MHD Bifrost simulation, we show that the TFBI develops in many of the colder regions in the chromosphere. This paper also presents the first multi-fluid simulation of the TFBI and validates this new result by demonstrating close agreement with theory during the linear regime. The simulation eventually develops turbulence, and we characterize the resulting wave-driven heating, plasma transport, and random motions. These results all contend that effects of the TFBI contribute to the discrepancies between solar observations and radiative MHD models.

description: We introduce an iterative solution to the problem of interference alignment (IA) over MIMO channels based on a message-passing formulation. We propose a parameterization of the messages that enables the computation of IA precoders by a min-sum algorithm over continuous variable spaces -- under this parameterization, suitable approximations of the messages can be computed in closed-form. We show that the iterative leakage minimization algorithm of Cadambe et al. is a special case of our message-passing algorithm, obtained for a particular schedule. Finally, we show that the proposed algorithm compares favorably to iterative leakage minimization in terms of convergence speed, and discuss a distributed implementation.

description: A number of platform economy services are composite insofar as they consist of an element provided by electronic means and another that is not provided by electronic means. Determining whether platforms provide only the online intermediation service or an overall service comprising the underlying physical service as well is instrumental in ascertaining which EU law provisions apply to these platforms. The aim of this Insight is to explore the legal classification of composite platform economy services and its policy implications, in order to propose a way forward at the moment when the Commission is drafting a proposal for a new Digital Services Act (DSA).

Estimate on dust scale height from continuum image of the HD 163296 protoplanetary disk
Creators: name: Doi, Kiyoaki
Publisher: name: Zenodo
Year: 2020

description: We aim at estimating the dust scale height of protoplanetary disks from millimeter continuum observations. First, we present a general expression of intensity of a ring in a protoplanetary disk, and show that we can constrain the dust scale height by the azimuthal variation of the intensity. Then, we apply the presented methodology to the two distinct rings at 68 au and at 100 au of the protoplanetary disk around HD 163296. We constrain the dust scale height by comparing the DSHARP high-resolution millimeter dust continuum image with radiative transfer simulations using RADMC-3D. We find that hd/hg > 0.55 at the inner ring and hd/hg < 0.44 at the outer ring in the 2 ? error range, where hd is the dust scale height and hg is the gas scale height. This indicates that the dust is flared at the inner ring and settled at the outer ring. We further constrain the ratio of turbulence parameter ? to gas-to-dust-coupling parameter St from the derived dust scale height; ?/St > 0.48 at the inner ring, and ?/St < 0.19 at the outer ring. This results show that the turbulence is stronger or the dust is smaller at the inner ring than at the outer ring.

description: Axions are hypothetical particles that were postulated to solve one of the puzzles arising in the standard model of particle physics, namely the strong CP (Charge conjugation and Parity) problem. The new International AXion Observatory (IAXO) will incorporate the most promising solar axions detector to date, which is designed to enhance the sensitivity to the axion-photon coupling by one order of magnitude beyond the limits of the current state-of-the-art detector, the CERN Axion Solar Telescope (CAST). The IAXO detector relies on a high-magnetic field distributed over a very large volume to convert solar axions into X-ray photons. Inspired by the successful realization of the ATLAS barrel and end-cap toroids, a very large superconducting toroid is currently designed at CERN to provide the required magnetic field. This toroid will comprise eight, one meter wide and twenty one meter long, racetrack coils. The system is sized 5.2 m in diameter and 25 m in length. Its peak magnetic field is 5.4 T with a stored energy of 500 MJ. The magnetic field optimization process to arrive at maximum detector yield is described. In addition, materials selection and their structure and sizing has been determined by force and stress calculations. Thermal loads are estimated to size the necessary cryogenic power and the concept of a forced flow supercritical helium based cryogenic system is given. A quench simulation confirmed the quench protection scheme.
