Abstract
Turbulence is ubiquitous in space and astrophysical plasmas, such as the solar wind, planetary magnetospheres, and the interstellar medium. It plays a key role in converting electric and magnetic energies into kinetic energy of the plasma particles. Here, the properties of MHD and kinetic-scale magnetic fluctuations in the Mercury environment are investigated using data collected by the MESSENGER spacecraft from 2011 March 23 to 2015 April 28. It is found that spectral indices at MHD scales vary from ∼−5/3 in the near-Planet solar wind (possibly the foreshock) to ∼−1.3 within the magnetosheath close to bow shock. The spectra steepen further in the magnetosheath close to magnetopause, and reach ∼−2.2 within the magnetosphere. Only 15% of events were found to have the Kolmogorov scaling ∼−5/3 in the magnetosheath. The high variability of the spectral indices implies that the scaling of turbulent fluctuations in the magnetosheath is not universal, and it emphasizes the role of the bow shock on the turbulence dynamics, at least at the largest scales. Analysis of the magnetic compressibility shows that only ∼30% of events with Kolmogorov inertial range in the magnetosheath are dominated by (shear) Alfvénic fluctuations, which contrasts with well-known features of solar wind turbulence. At kinetic scales, the steepest spectra (slopes ∼−2.8) occur in the solar wind, before flattening to ∼−2 near the bow shock, then steepening again to ∼−2.8 in the magnetosheath. The spectral indices at kinetic scales are close to the ones at large scales in the magnetosphere, which may be caused by the presence of heavy ions in the latter. The statistical results are compared with previous observations reported in other planetary plasma environments.
HST/COS Observations of Quasar Outflows in the 500–1050 Å Rest Frame. II. The Most Energetic Quasar Outflow Measured to Date
Authors: Xu Xinfeng , Arav Nahum , Miller Timothy , Kriss Gerard A. , Plesha Rachel 
Published: March 2020

Abstract
We present a study of the BAL outflows seen in quasar SDSS J1042+1646 (z = 0.978) in the rest-frame 500–1050 Å (EUV500) region. The results are based on the analysis of recent Hubble Space Telescope/Cosmic Origins Spectrograph observations. Five outflow systems are identified, where, in total, they include ∼70 outflow troughs from ionic transitions. These include the first non-solar detections from transitions of O v*, Ne v*, Ar vi, Ca vi, Ca vii, and Ca viii. The appearance of very high-ionization species (e.g., Ne viii, Na ix, and Mg x) in all outflows necessitates at least two ionization phases for the observed outflows. We develop an interactive Synthetic Spectral Simulation method to fit the multitude of observed troughs. Detections of density sensitive troughs (e.g., S iv* λ661.40 Å and the O v* multiplet) allow us to determine the distance of the outflows (R) as well as their energetics. Two of the outflows are at R ≃ 800 pc and one is at R ≃ 15 pc. One of the outflows has the highest kinetic luminosity on record (

erg s−1), which is 20% of its Eddington luminosity. Such a large ratio suggests that this outflow can provide the energy needed for active galactic nucleus feedback mechanisms.
YZiCS: Unveiling the Quenching History of Cluster Galaxies Using Phase-space Analysis
Authors: Rhee Jinsu , Smith Rory , Choi Hoseung , Contini Emanuele , Jung S. Lyla , Han San , Yi Sukyoung K. 
Published: March 2020

Abstract
We used the time since infall (TSI) of galaxies, obtained from the Yonsei Zoom-in Cluster Simulation, and the star formation rate (SFR) from the Sloan Digital Sky Survey Data Release 10 to study how quickly the star formation of disk galaxies is quenched in cluster environments. We first confirm that both simulated and observed galaxies are consistently distributed in phase space. We then hypothesize that the TSI and SFR are causally connected; thus, both the TSI and SFR of galaxies at each position of phase space can be associated through abundance matching. Using a flexible model, we derive the star formation history (SFH) of cluster galaxies that best reproduces the relationship between the TSI and SFR at z ∼ 0.08. According to this SFH, we find that galaxies with M

⊙ generally follow the so-called “delayed-then-rapid” quenching pattern. Our main results are as follows: (i) part of the quenching takes place outside clusters through mass quenching and preprocessing. The e-folding timescale of this “ex situ quenching phase” is roughly 3 Gyr with a strong inverse mass dependence. (ii) The pace of quenching is maintained roughly for 2 Gyr (“delay time”) during the first crossing time into the cluster. During the delay time, quenching remains gentle, probably because gas loss happens primarily on hot and neutral gases. (iii) Quenching becomes more dramatic (e-folding timescale of roughly 1 Gyr) after delay time, probably because ram pressure stripping is strongest near the cluster center. Counterintuitively, more massive galaxies show shorter quenching timescales mainly because they enter their clusters with lower gas fractions due to ex situ quenching.
Improving Geometric and Dynamical Constraints on Cosmology with Intrinsic Alignments of Galaxies
Authors: Taruya Atsushi , Okumura Teppei 
Published: March 2020

Abstract
We show that the spatial correlation of the intrinsic alignments (IAs) of galaxies, measured in galaxy redshift surveys, offers a precision route to improve the geometrical and dynamical constraints on cosmology. The IA has been treated as a contaminant against cosmological probes such as weak gravitational lensing experiments. However, the large-scale correlation of IAs is expected to follow the coherent large-scale matter inhomogeneities. Here, making use of its anisotropic nature, we show that the large-scale IA correlations help to improve the measurements of the geometric distances and growth of structure. In combination with the conventional galaxy clustering statistics, we find that constraints on equation-of-state parameter for dark energy and Hubble parameter can be tighter than those from the clustering statistics alone by a factor of more than 1.5.
A preliminary phylogeny of cave trechine beetles from China (Coleoptera: Carabidae: Trechini)
Authors: Huang Sunbin , Tian Mingyi , Faille Arnaud 
Published: March 2020

Coleoptera is one of the most successful groups among the subterranean fauna. Within Carabidae, 25 tribes have been reported in subterranean habitats, including the first representative of the tribe Patrobini, just described from Southern China. Amongst them, Trechini is the most diverse and cave-specialized group, and the numerous lineages of this group which have diversified underground make it an excellent model for the study of evolutionary mechanisms.
In China, 152 species within 52 genera of Trechini have been described so far. In order to unveil the relationships and origin of this remarkable biodiversity and to understand the evolutionary success of this group, we infer the first phylogeny of the group by using molecular sequence data from four genes (two mitochondrial markers: cox1 and 16S; plus two nuclear: 18S and 28S). We found that the Chinese cave Trechini do not form a monophyletic clade and we identified three main independent subterranean clades. To define the systematic position of the main clades on a worldwide scale, we gathered other Trechini sequence data from different lineages and part of the world. The preliminary results will be presented in this talk.
SURGICAL ANATOMY OF THE RADIAL NERVE IN THE ARM: PRACTICAL CONSIDERATIONS OF THE BRANCHING PATTERNS TO THE TRICEPS BRACHII
Authors: Stanescu Stephan , Post James , Ebraheim Nabil A , Bailey Alexander S , Yeasting Richard 
Published: March 2020

ABSTRACT
Thirty-three cadaveric dissections were performed to identify radial nerve branching patterns to the triceps brachii. Radial innervation of the long head of the triceps originated in the axilla in 88% of the cases and the brachio-axillary angle in 12%. Innervation of the medial head of the triceps originated in the spiral groove in 52% of the cases, the brachio-axillary angle in 39%, and the axilla in 9%. The lateral head was innervated by branches arising in the spiral groove in 70% of the cases, the brachio-axillary angle in 24%, and the axilla in 6%. On average, the radial nerve crossed the midline in the proximal 45% of the arm, 3 cm superior to the level of the deltoid insertion. An intramuscular tendon was present in the medial head of the triceps. The tendon, located medial to the midline of the arm, was seen in all specimens. This tendon serves as an interneural plane with nerve branches descending on either side, but never crossing from one side to the other. Due to the complexity of radial nerve branching, this tendon may be used as a reference plane for longitudinal splitting of the medial head minimizing the risk of nerve damage.
Air quality in the eastern United States and Eastern Canada for 1990–2015: 25 years of change in response to emission reductions of SO2 and NOx in the region
Authors: Feng Jian , Chan Elton , Vet Robert 
Published: March 2020

Abstract. SO2 and NOx are precursors to form sulfate, nitrate, and ammonium particles in the air, which account for more than 50 % of PM2.5 mass in the eastern US (Bell et al., 2007) and are dominant components of PM2.5 during many smog events (Dabek-Zlotorzynska et al., 2011). H2SO4 and HNO3, formed from the oxidation of SO2 and NOx, respectively, are the main sources of acid deposition through wet and dry depositions. NOx is also a precursor to the formation of tropospheric O3, which is an important atmospheric oxidant and is also essential for the formation of other atmospheric oxidants, such as OH and H2O2. In the past 26 years from 1990 to 2015, emissions of SO2 and NOx in the US were significantly reduced from 23.1 and 25.2 million t yr−1 in 1990 to 3.7 and 11.5 million t yr−1 in 2015, respectively. In Canada, SO2 and NOx were reduced by 63 % and 33 % from 1990 to 2014. In response to the significant reductions of SO2 and NOx emissions, air quality in the eastern US and Eastern Canada improved tremendously during 1990–2015. In this study, we analyzed surface air concentrations of SO42-, NO3-, NH4+, HNO3,
and SO2 measured weekly by the Clean Air Status and Trends Network (CASTNET) in the US and measured daily from the Canadian Air and
Precipitation Monitoring Network (CAPMoN) in Canada to reveal the temporal
and spatial changes in each species during the 25-year period. For the whole
eastern US and Eastern Canada, the annual mean concentrations of
SO42-, NO3-, NH4+, HNO3, SO2, and TNO3 (NO3- + HNO3, expressed as the mass of equivalent NO3-) were reduced by 73.3 %, 29.1 %, 67.4 %, 65.8 %, 87.6 %, and 52.6 %, respectively, from 1990 to 2015. In terms of percentage, the reductions of all species except NO3- were spatially uniform. The reductions of SO2 and HNO3 were similar in the warm season (May–October) and the cold season (November–April), and the reductions of SO42-, NO3-, and NH4+ were more
significant in the warm season than in the cold season. The reductions of
SO42- and SO2 mainly occurred in 1990–1995 and 2007–2015 during the warm season and in 1990–1995 and 2005–2015 during the cold season. The reduction of NO3- mainly occurred in the Midwest after 2000. Other than in the Midwest, NO3- exhibited very little change during the cold season for the period. The reduction of NH4+ generally followed the reduction trend of SO42-; especially after 2000, the temporal trend of NH4+ was almost identical to that of SO42-. The ratio of S in SO42- to total S in SO42- plus SO2, as well as the ratio of NO3- to TNO3 increased by more than 50 % during the period. This indicates that a notable change in regional chemistry took place from the beginning to the end of the period, with a higher percentage of SO2 being oxidized to SO42- and a higher percentage of HNO3 being neutralized to NH4NO3 near the end of the period.

Abstract. The speciation of dissolved iron (DFe) in the ocean is widely
assumed to consist almost exclusively of Fe(III)-ligand complexes. Yet in
most aqueous environments a poorly defined fraction of DFe also exists as
Fe(II), the speciation of which is uncertain. Here we deploy flow injection
analysis to measure in situ Fe(II) concentrations during a series
of mesocosm/microcosm/multistressor experiments in coastal environments in
addition to the decay rate of this Fe(II) when moved into the dark. During
five mesocosm/microcosm/multistressor experiments in Svalbard and Patagonia,
where dissolved (0.2 µm) Fe and Fe(II) were quantified
simultaneously, Fe(II) constituted 24 %–65 % of DFe, suggesting that
Fe(II) was a large fraction of the DFe pool. When this Fe(II) was allowed to
decay in the dark, the vast majority of measured oxidation rate constants
were less than calculated constants derived from ambient temperature,
salinity, pH, and dissolved
O2. The oxidation rates of Fe(II) spikes added to Atlantic seawater
more closely matched calculated rate constants. The difference between
observed and theoretical decay rates in Svalbard and Patagonia was most
pronounced at Fe(II) concentrations <2 nM, suggesting that the effect may
have arisen from organic Fe(II) ligands. This apparent enhancement of Fe(II)
stability under post-bloom conditions and the existence of such a high
fraction of DFe as Fe(II) challenge the assumption that DFe speciation in
coastal seawater is dominated by ligand bound-Fe(III) species.
USE OF AGRICULTURAL SERVICES IN EUROPEAN UNION REGIONS – A TYPOLOGICAL ANALYSIS
Authors: Kołodziejczak Małgorzata 
Published: March 2020

The purpose of this paper is to identify types that represent differing classes of European Union regions and agricultural service consumption indicators as of 2017. A comparison of the characteristics of agricultural farms in the identified types was used to search for a relationship between selected farm characteristics and the level of use of agricultural services. Data from the Farm Accountancy Data Network (FADN) were used in the research. The analysis covered 131 FADN regions located in 25 countries. The Ward method clustering procedure resulted in identifying five types of EU regions differing from one another in service consumption levels and selected agricultural indicators. The costs of agricultural services per hectare of agricultural land was the lowest on farms classified as types with the lowest average area of agricultural land (I and II), higher on farms encompassed by the types with a high average area of agricultural land (III and V), while in the type composed of regions with the highest average area of agricultural land (IV), it was lower than in types III and V. It can be supposed that farms with a small area of agricultural land almost exclusively used own equipment, neighborhood assistance and joint machinery ownership, while limiting the use of commercial agricultural services. Agricultural farms classified as the fourth type of regions primarily used own high-effective machines in plant production, while on large farms, but not large-scale farms, it was economically more favorable to purchase the services. The costs of agricultural services per 1 AWU were subject to similar regularities as the costs of agricultural services per hectare of agricultural land.
INSTITUTIONAL BARRIERS TO THE DEVELOPMENT OF ORGANIC FARMING IN POLAND
Authors: Łuczka Władysława 
Published: March 2020

The purpose of this paper is to identify and describe institutional barriers to the development of organic farming in Poland. As a secondary objective, this paper seeks feedback from organic farmers on measures taken by the institutional environment to promote the development of organic farming. This paper is based on literature reviews and selected findings from empirical research carried out in 2019 with 262 organic farms. The sample used in this study was representative of the general population of certified organic farms. The survey was a CAWI. The study found that organic farming faces many barriers, with frequent amendments to regulations being of key importance. This destabilizes and adds uncertainty to the functioning of organic farms. Another significant barrier are the high standards of organic production and low levels of financial and non-financial support. To a certain extent, these barriers result from the inefficiency of institutions surrounding organic farming. As a consequence, they are considered to poorly contribute to organic farming development.
