AbstractEndometriosis is a chronic inflammatory disease associated with an impaired immune response at the site of lesion implantation. The ability of macrophages to respond to changes in their environment is critical for an effective immune response. However, the existing knowledge of the peritoneal immune cell populations, their activation state and contribution to the immunological changes that occur in endometriosis are still controversial and inconclusive. In this study, we have examined the relative abundance of peritoneal macrophage subtypes, in women with (n = 21) versus without (n = 18) endometriosis and disease-associated changes in the adaptive T cell response. Using flow cytometry, we showed that peritoneal fluid monocyte/macrophages are composed of two populations of cells that exhibit major differences in the levels of the CD14 and CD68 markers, which we classified as the CD14+low/CD68+low and CD14+high/CD68+high subpopulations. Moreover, endometriosis-associated changes in the macrophage subtypes occurred only in the CD14+low/CD68+low subpopulation. In this subpopulation, we found an increased macrophage type 2 response that was coupled with an increase in peritoneal T-helper 2 and T-regulatory cell populations in women with endometriosis, compared with controls. In summary, this study resolves conflicting data in the literature regarding changes in the peritoneal immune cell population in endometriosis and identifies CD14+low/CD68+low macrophages as the subpopulation that changes in response to the disease.
Ultraholomorphic extension theorems in the mixed setting
Authors: Jiménez-Garrido Javier , Sanz Javier , Schindl Gerhard 
Published: June 2020

AbstractThe aim of this work is to generalize the ultraholomorphic extension theorems from V. Thilliez in the weight sequence setting and from the authors in the weight function setting (of Roumieu type) to a mixed framework. Such mixed results have already been known for ultradifferentiable classes and it seems natural that they have ultraholomorphic counterparts. In order to have control on the opening of the sectors in the Riemann surface of the logarithm for which the extension theorems are valid we are introducing new mixed growth indices which are generalizing the known ones for weight sequences and functions. As it turns out, for the validity of mixed extension results the so-called order of quasianalyticity (introduced by the second author for weight sequences) is becoming important.
MITCHELL-INSPIRED FORCING, WITH SMALL WORKING PARTS AND COLLECTIONS OF MODELS OF UNIFORM SIZE AS SIDE CONDITIONS, AND GAP-ONE SIMPLIFIED MORASSES
Authors: MORGAN CHARLES 
Published: June 2020

AbstractWe show that a
$(\kappa ^{+},1)$
-simplified morass can be added by a forcing with working parts of size smaller than
$\kappa $
. This answers affirmatively the question, asked independently by Shelah and Velleman in the early 1990s, of whether it is possible to do so.Our argument use a modification of a technique of Mitchell’s for adding objects of size
$\omega _2$
in which collections of models – all of equal, countable size – are used as side conditions. In our modification, whilst the individual models are, as in Mitchell’s technique, taken ad hoc from quite general classes, the collections of models are very highly structured, in a way that is somewhat different from, perhaps more stringent than, Mitchell’s original, arguably making the method more wieldy and giving the prospect of further uses with more delicate working parts.

Published: June 2020

ABSTRACTAnnually resolved tree-ring samples of the time period 1625–1510 BCE were analyzed from the German oak tree-ring chronology. Blocks of the same tree rings were previously used to generate IntCal calibration data. The new dataset shows an offset to the calibration data IntCal13 of 24 years and resembles annual data for the same time period derived from tree-ring records in other growth locations. A subset of samples of the period 1625–1585 BCE was additionally measured in three other laboratories (ETH, AAR, AA) for quality control.

ABSTRACTWith the popularization of carbon and nitrogen stable-isotope analysis methods used on archaeological samples from Xinjiang, the ancient paleodiet there has been revealed. However, research about isotopic analysis combined with environmental factors is rare, especially in such a variable and complex climate as that of the Tianshan region. We systematically analyzed the δ13C and δ15N results from animals and humans for dietary reconstruction of nomadic pastoralists from the Tianshan region during 3900–1200 cal BP. The δ13C and δ15N values for animals (sheep/goat, horse and cattle; n = 57) have a wide range from –20.8‰ to –14.7‰ for δ13C (–19.2 ± 1.0‰) and 3.2‰ to 9.9‰ for δ15N (7.0 ± 1.2‰). The δ13C and δ15N values from humans range from –19.6 to –12.3‰ (–16.0 ± 1.5‰) and 7.1 to 16.7‰ (–13.6 ± 1.5‰), respectively. The animal δ15N results indicate that the dry environment in the Tianshan region may result in elevated δ15N values. Synthesizing animal and human isotope results suggests that the inhabitants engaged in mobile herding economies subsidized with crops and wild animal meat from the Tianshan Mountains. In conclusion, we found that the regional environment closely relates to crop types, and temporal climate change has an effect on human dietary structure. Therefore, climate condition cannot be ignored when studying human paleodiet.
Terrestrial kaolin deposits trapped in Miocene karstic sinkholes on planation surface remnants, Transdanubian Range, Pannonian Basin (Hungary)

Published: June 2020

AbstractIn the Transdanubian Range, Pannonian Basin, Hungary, karstic sinkholes on a planation surface of Triassic carbonates are filled by grey clayey–silty kaolin deposits. The provenance and accumulation age of these strongly altered terrestrial karst-filling sediments are constrained by X-ray powder diffraction, heavy mineral analysis and zircon U–Pb dating. The heavy minerals of the Southern Bakony Mountains samples are dominated by the ultra-stable zircon–rutile–tourmaline association. Zircon U–Pb data indicate accumulation between 20 and 16 Ma. Furthermore, Archaean to Palaeogene grains were also determined, reflecting the principally fluvial recycling of Eocene bauxites and their cover sequences. In contrast, the sample from the Keszthely Hills consists almost exclusively of airborne material including zircons of 18–14 Ma, reflecting a dominant contribution from the Carpathian–Pannonian Neogene volcanism. The shift in the Miocene age components is inferred to have been caused by the landscape evolution and burial history of the planation surface remnants controlled by local block tectonics.
Do Women Make More Credible Threats? Gender Stereotypes, Audience Costs, and Crisis Bargaining
Authors: Schwartz Joshua A. , Blair Christopher W. 
Published: June 2020

AbstractAs more women attain executive office, it is important to understand how gender dynamics affect international politics. Toward this end, we present the first evidence that gender stereotypes affect leaders’ abilities to generate audience costs. Using survey experiments, we show that female leaders have political incentives to combat gender stereotypes that women are weak by acting “tough” during international military crises. Most prominently, we find evidence that female leaders, and male leaders facing female opponents, pay greater inconsistency costs for backing down from threats than male leaders do against fellow men. These findings point to particular advantages and disadvantages women have in international crises. Namely, female leaders are better able to tie hands—an efficient mechanism for establishing credibility in crises. However, this bargaining advantage means female leaders will also have a harder time backing down from threats. Our findings have critical implications for debates over the effects of greater gender equality in executive offices worldwide.
A Goudstikker van Goyen in Gdańsk: A Case Study of Nazi-Looted Art in Poland
Authors: Grimsted Patricia Kennedy 
Published: June 2020

Abstract:This article traces the provenance and migration of a painting by Jan van Goyen (1595–1656),River Landscape with a Swineherd, from the Jacques Goudstikker Collection and now in Gdańsk Muzeum Narodowe. After the “red-flag sale” of the Goudstikker Collection in July 1940 to German banker Alois Miedl, and then to Hermann Göring, this painting—after its sale on Berlin’s Lange Auction in December 1940 to Hitler’s agent Almas-Dietrich—was returned to Miedl-Goudstikker in Amsterdam. Miedl then sold it (with two other Dutch paintings) to the Nazi Gauleiter of Danzig, Albert Forster, among many wartime Dutch acquisitions for the Municipal Museum (Stadtmuseum). Evacuated to Thuringia and captured by a Soviet trophy brigade, it thus avoided postwar Dutch claims. Returned to Poland from the Hermitage in 1956, it was exhibited in the Netherlands and the United States (despite its Goudstikker label). Tracing its wartime and postwar odyssey highlights the transparent provenance research needed for Nazi-era acquisitions, especially in former National Socialist (NS) Germanized museums in countries such as Poland, where viable claims procedures for Holocaust victims and heirs are still lacking. This example of many “missing” Dutch paintings sold to NS-era German museums in cities that became part of postwar Poland, raises several important issues deserving attention in provenance research for still-displaced Nazi-looted art.
Quasi-elliptic dual-band bandpass filters based on series-cascaded multi-resonant cells
Authors: Ashley Andrea , Simpson Dakotah J. , Psychogiou Dimitra 
Published: June 2020

AbstractThis paper reports on quasi-elliptic dual-band bandpass filters (BPFs) that were designed for the Filter Student Design Competition of the 2019 European Microwave Week. The proposed lumped-element (LE) BPF concept is based on two dual-band transversal cells and one multi-resonant cell that allow the realization of symmetric and asymmetric dual-band transfer functions shaped by six poles and five transmission zeros. A compact implementation scheme based on LE series resonators is proposed for size compactness and wide spurious free out-of-band response. For proof-of-concept demonstration purposes, a dual-band LE prototype with two passbands centered 1 and 1.5 GHz was designed, manufactured, and measured. It exhibited the following radio frequency measured performance characteristics. Passbands centered at 1.02 and 1.45 GHz, minimum insertion loss levels of 2.0 and 2.7 dB, and bandwidth of 146 and 105 MHz, respectively, for the first and the second passband, and out-of-band rejection >30 dB between 0 and 894 MHz, 1.17–1.34 GHz, and 1.72–6.9 GHz.
Giant reed (Arundo donax) responses to herbicides in a greenhouse study
Authors: Liu Mingyang , Hulting Andrew , Mallory-Smith Carol 
Published: June 2020

AbstractGiant reed recently was promoted as a biofuel crop in Oregon. Because giant reed is a highly invasive plant in North American rivers, the planting of this species in Oregon is a cause for concern to scientists and local land managers. However, some growers in the area were interested in producing giant reed as a rotational crop. To find potential herbicides to control the giant reed or to control it as a volunteer, 13 foliar and 13 cut-and-spray herbicide treatments were preevaluated in greenhouse studies. We chose 10% and 85% reduction in aboveground biomass for either crop safety or control, respectively. When applied at the standard rates, acetochlor and dimethenamid-p reduced aboveground dry biomass of the crop by 10% or less. Acetochlor+atrazine, atrazine, flufenacet, and mesotrione reduced aboveground biomass of the crop by at least 85%, indicating that these compounds have the potential to serve as controls against giant reed.
Response of the Equatorial Ionosphere to the Annular Solar Eclipse of 15 January 2010

Published: June 2020

AbstractThis paper presents the response of the equatorial ionosphere to the noon time annular solar eclipse of 15 January 2010. The observation has been made using a Digisonde, Meteor Wind Radar, and Proton Precession Magnetometer over Trivandrum, (8.5oE; 77oN; dip lat 0.5oN), a geomagnetic dip equatorial station in India. It has been found that the E, F1, and F2 regions of the equatorial ionosphere respond to solar eclipse with different time delays, F1 being responding faster and the E and F2 regions slower. Though there have been studies on the delayed response of F2 region during the solar eclipses, the delayed response of E region is quite unexpected since this region is dominated by the recombination chemistry. The plausible reasons for this have been explored, and it is suggested that the downward diffusion of atomic oxygen plays a major role for the observed phenomenon.

AbstractThe lunar floor‐fractured crater Gassendi and surrounding area were examined with high‐resolution Lunar Reconnaissance Orbiter imagery and other remote sensing data to characterize and understand the volcanic processes in the southwestern region of the Moon. This study was selected because the Gassendi region exhibits a variety of volcanic features (e.g., cryptomaria deposits, pyroclastic deposits, maria, and lava lakes) and team participants have studied this region for 30 years (Hawke et al., 1991, https://doi.org/10.1029/92GL02921). This study confirms the existence of a previously identified cryptomare deposit and identifies an additional cryptomare deposit west of Gassendi crater and a pyroclastic northeast of Gassendi. Spectral and geochemical anomalies associated with dark‐haloed impact craters reveal cryptomaria deposits in the western Gassendi crater floor and previously unmapped mare basalt within northeastern Gassendi. We identified three separate lava lakes on the northeast, northwest, and southwest floor of Gassendi crater based on morphology analogous to terrestrial lava lakes, geochemical signatures, and digital terrain data. Crater count (model) age data suggest that the lava lakes were active at ~3.6 Ga (300 Ma after floor emplacement). Criteria used to identify lava lakes in Gassendi were applied globally to locate candidate lava lakes within floor‐fractured craters. With the identification of lava lake morphology, both in Gassendi crater and in other floor‐fractured craters, the current ascent and eruption models should be revised to allow for at least short‐term connection between magma supply at depth and surface lava lakes. Hence, this integration of multiple perspectives afforded by recent remote data sets reveals new views about lunar volcanic processes.
Evolution and Propagation of an Active Plate Boundary: U‐Pb Ages of Fault‐Related Calcite From the Dead Sea Transform

Published: June 2020

AbstractWe utilize in situ U‐Pb geochronology of fault‐related calcite to date faulting activity along the Dead Sea Transform (DST) plate boundary and constrain the evolution of continental breakup. U‐Pb ages from 30 well‐constrained Tera‐Wasserburg data sets of syntectonic calcite precipitates along the northern part of the DST delineate two key periods of faulting activity: (1) Maastricht (latest Cretaceous) to Eocene (70–37 Ma) and (2) middle Miocene (18–10 Ma). The latter period is more extensive and is associated with normal and left‐lateral shearing deformation. Ages of ~18 Ma, obtained from the western and eastern most strands (~20 km apart), indicate that branching in the northern DST occurred during the initial stage of the DST development. Comparison of the new ages from the northern part of the DST with U‐Pb ages from the southern part highlights prominent faulting activity during the early to middle Miocene (20–10 Ma), with earliest ages of ~18 Ma in the south and younger ages of ~14 Ma in the north. This pattern suggests that the genesis of this plate boundary started adjacent to the Red Sea rift and migrated from south to north during a 3.5–4 Ma period (between 18 and 14 Ma) at an average rate of 11–13 cm/year. Such propagation data can be used to decipher the mechanical evolution of the lithosphere along evolving plate boundaries.
Pre‐breakup Extension in the Northern North Sea Defined by Complex Strain Partitioning and Heterogeneous Extension Rates

Published: June 2020

AbstractThe early stages of continental rifting are accommodated by the growth of upper crustal normal fault systems that are distributed relatively evenly across the rift width. Numerous fault systems define fault arrays, the kinematics of which are poorly understood due to a lack of regional studies drawing on high‐quality subsurface data. Here we investigate the long‐term (~150 Myr) growth of a rift‐related fault array in the East Shetland Basin, northern North Sea, using a regionally extensive subsurface data set comprising 2‐D and 3‐D seismic reflection surveys and 107 boreholes. We show that rift‐related strain during the pre‐Triassic to Middle Triassic was originally distributed across several subbasins. The Middle to Late Triassic saw a decrease in extension rate (~14 m/Myr) as strain localized in the western part of the basin. Early Jurassic strain initially migrated eastward, before becoming more diffuse during the main, Middle‐to‐Late Jurassic rift phase. The highest extension rates (~89 m/Myr) corresponded with the main rift event in the East Shetland Basin, before focusing of strain within the rift axis and ultimate abandonment of the East Shetland Basin in the Early Cretaceous. We also demonstrate marked spatial variations in timing and magnitude of slip along strike of major fault systems during this protracted rift event. Our results imply that strain migration patterns and extension rates during the initial, prebreakup phase of continental rifting may be more complex than previously thought; this reflects temporal and spatial changes in both thermal and mechanical properties of the lithosphere, in addition to varying extension rates.

AbstractExtreme and persistent haze events frequently occur during wintertime China. While recent emissions reductions reduced annual mean fine particulate matter (PM2.5) concentrations over eastern China, their effectiveness on wintertime PM2.5 trend remains uncertain. We use observations and model simulations to quantify seasonal differences in PM2.5 trends and investigate the underlying chemical mechanisms driving such differences. We find a much slower decrease in observed wintertime PM2.5 (−3.2% yr−1) since 2014, in contrast to a drastic summertime decrease (−10.3% yr−1). Simulations show two previously underappreciated mechanisms buffering wintertime PM2.5 decrease, including an increase in oxidation capacity due to nitrogen oxides (NOx) reductions under wintertime volatile organic compound (VOC)‐limited chemistry, and an enhanced conversion of nitric acid to nitrate by ammonia due to sulfur dioxide reductions. Our findings suggest that control policies targeting VOC and deep NOx reductions are needed to improve wintertime PM2.5 air quality over China.

AbstractEastern Boundary Upwelling Systems (EBUSs) are coastal hotspots of the potent greenhouse gas nitrous oxide (N2O). However, estimates of their emissions suffer from large uncertainties due to their significant spatial and temporal heterogeneity. Here, we derive the first multiyear, monthly resolution N2O emissions from three of the four major EBUSs using high‐frequency coastal atmospheric measurements and an inverse method. We find average combined N2O emissions from the northern California, Benguela, and southern Canary upwelling systems to be 57.7 (51.4–63.9) Gg‐N yr−1. We also find an offshore region near the Benguela EBUS that exhibits large pulses of emissions with emissions that reach 677 Gg‐N yr−1 in 1 month. Our findings highlight that atmospheric measurements coupled with inverse modeling can capture the large variability in EBUS emissions by quantifying emissions over large spatial distances and over long time periods compared to previous methods using traditional oceanographic measurements.

AbstractBetween 1992 and 2017, the Antarctic Ice Sheet (AIS) lost ice equivalent to 7.6 ± 3.9 mm of sea level rise. AIS mass loss is mitigated by ice shelves that provide a buttress by regulating ice flow from tributary glaciers. However, ice‐shelf stability is threatened by meltwater ponding, which may initiate, or reactivate preexisting, fractures, currently poorly understood processes. Here, through ground penetrating radar (GPR) analysis over a buried lake in the grounding zone of an East Antarctic ice shelf, we present the first field observations of a lake drainage event in Antarctica via vertical fractures. Concurrent with the lake drainage event, we observe a decrease in surface elevation and an increase in Sentinel‐1 backscatter. Finally, we suggest that fractures that are initiated or reactivated by lake drainage events in a grounding zone will propagate with ice flow onto the ice shelf itself, where they may have implications for its stability.
