Historical Disaster Exposure and Household Preparedness Across the United States
Authors: Malmin Natasha P. 
Published: January 2020

ABSTRACTObjectives:The study determined whether households in disaster-exposed communities were more likely to be prepared.Methods:Three measures of preparedness were created using the 2013 American Housing Survey: cumulative, adequate, and minimal preparedness. Cumulative and adequate preparedness were created based on the existing literature. Minimal preparedness measured whether households had at present food, water, access to a vehicle, and funds with which to evacuate. Disaster exposure was measured using historical FEMA disaster declarations. The various preparedness measures were regressed onto historical disaster exposure, controlling for sociodemographic factors.Results:Across all measures of preparedness, historical disaster exposure was a statistically significant predictor of preparedness. Vulnerable households included those where children or the disabled were present. African-American headed households emerged as vulnerable only when minimal preparedness was assessed.Conclusions:Prior disaster exposure increased household preparedness regardless of how preparedness was defined. However, assessing minimal preparedness may better reflect the changing disaster landscape where more and more households are asked to evacuate or shelter-in-place by policy-makers.
RELIABILITY OF AMS 14C DATES OF MOSS TEMPER PRESERVED IN NEOLITHIC POTTERY FROM THE SCHELDT RIVER VALLEY (BELGIUM)

Published: January 2020

ABSTRACTDirect dates of pottery obtained from food crusts or other organic residues on the vessel surfaces can be affected by a reservoir effect and/or an old wood effect and therefore be unreliable. Hence, there is a need for alternative ways to directly date pottery. Moss is used as temper by several cultural groups of the late 6th to early 4th millennium cal BC in northwestern Europe. After the pottery is fired, charred moss remains are often preserved in the clay, so that relatively short-lived plant material with a direct chronological link to the pottery and human occupation is available for radiocarbon (14C) dating. In this study, charred moss temper is extracted for accelerator mass spectrometry (AMS) 14C dating from pottery of the Swifterbant Culture and Spiere group in the Scheldt river valley (Belgium). The moss dates are then compared to reference dates of organic macro-remains from the same sites and food crust dates with or without a reservoir effect of the same pottery. Eleven out of 13 moss dates are in line with the expected pottery age. The paired dates of moss temper and food crusts from the same potsherds confirm a freshwater reservoir effect (FRE) for the latter. We conclude that moss temper has great potential as a sample material for direct pottery dating. However, more research on the extraction and pretreatment of moss temper as well as on the reliability of moss dates is necessary in the future.

AbstractThe effect of holly polyphenols (HP) on intestinal inflammation and microbiota composition was evaluated in a piglet model of lipopolysaccharide (LPS)-induced intestinal injury. A total of twenty-four piglets were used in a 2 × 2 factorial design including diet type and LPS challenge. After 16 d of feeding with a basal diet supplemented with or without 250 mg/kg HP, pigs were challenged with LPS (100 μg/kg body weight) or an equal volume of saline for 4 h, followed by analysis of disaccharidase activities, gene expression levels of several representative tight junction proteins and inflammatory mediators, the SCFA concentrations and microbiota composition in intestinal contents as well as proinflammatory cytokine levels in plasma. Our results indicated that HP enhanced intestinal disaccharidase activities and reduced plasma proinflammatory cytokines including TNF-α and IL-6 in LPS-challenged piglets. Moreover, HP up-regulated mRNA expression of intestinal tight junction proteins such as claudin-1 and occludin. In addition, bacterial 16S rRNA gene sequencing showed that HP altered hindgut microbiota composition by enriching Prevotella and enhancing SCFA production following LPS challenge. These results collectively suggest that HP is capable of alleviating LPS-triggered intestinal injury by improving intestinal disaccharidase activities, barrier function and SCFA production, while reducing intestinal inflammation.
War against “Internal Enemies”: Dr. Franz Lucas's Sterilization of Sinti and Roma in Ravensbrück Men's Camp in January 1945
Authors: Wisely Andrew 
Published: January 2020

AbstractFollowing the passing of the “Law for the Prevention of Offspring with Genetic Diseases” in July 1933, sterilization became a means to tighten the borders of the German ethnic community against outsiders, including Sinti and Roma. For a while, Sinti soldiers were spared sterilization. After Himmler's Auschwitz decree of December 1942, they were deported to Auschwitz-Birkenau. They escaped the extermination of other Sinti and Roma in theZigeunerlageron the night of August 2, 1944, only because they represented a human shield deployable against advancing Russian troops. Still, the Reich insisted on sterilizing them and their families before placing them in front of enemy guns because they were still considered “internal enemies.” As a result, some forty Sinti men and boys were sterilized by Dr. Franz Lucas in the men's camp in Ravensbrück in January 1945. Focusing on their story challenges Lucas's portrayal as the victim of SS practices, a narrative that long benefitted from the testimony of non-Sinti prisoners. In addition, compensation agencies in Germany underestimated the ongoing effects of psychological trauma resulting from sterilization. Sinti victims who were subjected to an “expert assessment” of their blood purity before war's end underwent a renewed assessment of their productivity for German society after the war.
Unholy Crusaders: The Wehrmacht and the Reestablishment of Soviet Churches during Operation Barbarossa
Authors: Harrisville David 
Published: January 2020

AbstractDuring the summer and fall of 1941, as they took part in Operation Barbarossa—the invasion of the Soviet Union—Wehrmacht personnel paused to reopen churches that had been shuttered by the communist regime. These events, which drew enormous crowds, brought together conquerors and conquered in a surprising display of shared faith before being halted by a directive from the Führer. This article addresses the question of why they took place at all, given the genocidal nature of the campaign in which they were embedded, as well as what they can tell us about the role of religion in the Wehrmacht, its relationship to Nazi ideology, and the nature of the military occupation. The reopening ceremonies, it is argued, were the spontaneous outcome of a number of interrelated factors, including Nazi rhetoric, the pent-up yearnings of Soviet Christians, and above all the vision of the invasion as a religious crusade against an atheist power adopted by many chaplains and soldiers. Although often overlooked, religion remained a powerful force in the Wehrmacht, one that could serve both to undermine and justify Nazi goals. Further, the reopenings demonstrate the army's capacity for flexibility in its dealings with the population, particularly during the war's opening months.
POWERS OF THE MAXIMAL IDEAL AND VANISHING OF (CO)HOMOLOGY

Published: January 2020

AbstractWe prove that each positive power of the maximal ideal of a commutative Noetherian local ring is Tor-rigid and strongly rigid. This gives new characterizations of regularity and, in particular, shows that such ideals satisfy the torsion condition of a long-standing conjecture of Huneke and Wiegand.
THE OFFICE OF THE UNITED NATIONS HIGH COMMISSIONER FOR REFUGEES AND THE SOURCES OF INTERNATIONAL REFUGEE LAW
Authors: Goodwin-Gill Guy S. 
Published: January 2020

AbstractThe role of international organisations in international law-making tends to be downplayed in this largely State-centric world. The practice of UNHCR, however, is reason enough for a more sophisticated appreciation of the role that operational entities can play in stimulating State practice, and of how they may interact with and guide domestic courts in treaty interpretation and application. The ILC's recently completed projects on customary international law and subsequent agreements and practice encourage a cautious approach, but the high degree of judicialisation in refugee decision-making, the strong legal content in the international protection regime and the impact of UNHCR's operational activities open the way for institutional and grass-roots developments, keeping the law in closer touch with social and political realities and with the needs of those displaced.

AbstractThe stable isotope ratios of carbon (δ13C) and nitrogen (δ15N) and total mercury concentrations (THg) of the three marine catfish speciesAspistor luniscutis,Bagre bagreandGenidens genidenswere evaluated to understand their trophic relationship in northern Rio de Janeiro state, south-eastern Brazil. The δ13C was similar among the three marine catfishes, whereas δ15N was similar inA. luniscutisandB. bagreand lower inG. genidens. THg was higher inG. genidensand lower inB. bagre. The greater assimilation of Sciaenidae fishes and squids byA. luniscutisandB. bagreresulted in smaller isotopic niche areas and trophic diversity but higher isotopic niche overlap, trophic redundancy and evenness. ForG. genidens, the similar assimilation of all prey items resulted in the broadest isotopic niche among the marine catfishes. The higher mercury content inG. genidensis consistent with an increased important contribution of prey with a higher Hg burden. The bioaccumulation process was indicated by significant correlations of δ15N and THg with total length and total mass. Additionally, a significant correlation between THg and δ15N reflected the biomagnification process through the food web.
The role of meat in the European diet: current state of knowledge on dietary recommendations, intakes and contribution to energy and nutrient intakes and status

Published: January 2020

AbstractThe role of meat in the diet has come under scrutiny recently due to an increased public emphasis on providing healthy diets from sustainable food systems and due to health concerns relating to the consumption of red and processed meat. The present review aimed to summarise dietary guidelines relating to meat, actual meat intakes and the contribution of meat to energy and nutrient intakes of children, teenagers and adults in Europe. The available literature has shown that food-based dietary guidelines for most countries recommend consuming lean meat in moderation and many recommend limiting red and processed meat consumption. Mean intakes of total meat in Europe range from 40 to 160 g/d in children and teenagers and from 75 to 233 g/d in adults. Meat contributes to important nutrients such as protein, PUFA, B vitamins, vitamin D and essential minerals such as Fe and Zn; however, processed meat contributes to significant proportions of saturated fat and Na across population groups. While few data are available on diaggregated intakes of red and processed meat, where data are available, mean intakes in adults are higher than the upper limits recommended by the UK Scientific Advisory Committee on Nutrition (70 g/d) and the World Cancer Research Fund (500 g/week). While there are no recommendations for red and processed meat consumption in children and teenagers, intakes currently range from 30 to 76 g/d. The present review provides a comprehensive overview of the role of meat in the European diet which may be of use to stakeholders including researchers, policy makers and the agri-food sector.
A Study of Membrane Impact on Spatial Resolution of LiquidIn SituTransmission Electron Microscope
Authors: Li Ming , Knibbe Ruth 
Published: January 2020

AbstractMicrochip technology with electron transparent membranes is a key component forin situliquid transmission electron microscope (TEM) characterization. The membranes can significantly influence the TEM imaging spatial resolution, not only due to introducing additional material layers but also due to the associated bulging. The membrane bulging is largely defined by the membrane materials, thickness, and short dimension. The impact of the membrane on the spatial resolution, especially the extent of its bulging, was systematically investigated through the impact on the signal-to-noise ratio, chromatic aberration, and beam broadening. The optimization of the membrane parameters is the key component when designing thein situTEM liquid cell. The optimal membrane thickness of 50 nm was found which balances the impact of membrane bulging and membrane thickness. Beyond this, the short membrane window dimension and the chip nominal spacing should be minimized. However, these two parameters have practical limitations in regards to chip handling.

Published: January 2020

AbstractPurpose:The objective of this article is to evaluate the dosimetric efficacy of volumetric modulated arc therapy (VMAT) in comparison to dynamic conformal arc therapy (DCAT) and 3D conformal radiotherapy (3DCRT) for very small volume (≤1 cc) and small volume (≤3 cc) tumours for flattened (FF) and unflattened (FFF) 6 MV beams.Materials and methods:A total of 21 patients who were treated with single-fraction stereotactic radiosurgery, using either VMAT, DCAT or 3DCRT, were included in this study. The volume categorisation was seven patients each in <1, 1–2 and 2–3 cc volume. The treatment was planned with 6 MV FF and FFF beams using three different techniques: VMAT/Rapid Arc (RA) (RA_FF and RA_FFF), dynamic conformal arc therapy (DCA_FF and DCA_FFF) and 3DCRT (Static_FF and Static_FFF). Plans were evaluated for target coverage (V100%), conformity index, homogeneity index, dose gradient for 50% dose fall-off, total MU and MU/dose ratio [intensity-modulated radiotherapy (IMRT) factor], normal brain receiving >12 Gy dose, dose to the organ at risk (OAR), beam ON time and dose received by 12 cc of the brain.Result:The average target coverage for all plans, all tumour volumes (TVs) and delivery techniques is 96·4 ± 4·5 (range 95·7 ± 6·1–97·5 ± 2·9%). The conformity index averaged over all volume ranges <1, 2, 3 cc> varies between 0·55 ± 0·08 and 0·68 ± 0·04 with minimum and maximum being exhibited by DCA_FFF for 1 cc and Static_FFF/RA_FFF for 3 cc tumours, respectively. Mean IMRT factor averaged over all volume ranges for RA_FF, DCA_FF and Static_FF are 3·5 ± 0·8, 2·0 ± 0·2 and 2·0 ± 0·2, respectively; 50% dose fall-off gradient varies in the range of 0·33–0·42, 0·35–0·40 and 0·38–0·45 for 1, 2 and 3 cc tumours, respectively.Conclusion:This study establishes the equivalence between the FF and FFF beam models and different delivery techniques for stereotactic radiosurgery in small TVs in the range of ≤1 to ≤3 cc. Dose conformity, heterogeneity, dose fall-off characteristics and OAR doses show no or very little variation. FFF could offer only limited time advantage due to excess dose rate over an FF beam.
Correlating lung tumour location and motion with respiration using 4D CT scans
Authors: Siow T R. , Lim S K. 
Published: January 2020

AbstractBackground:Lung tumours, especially those in the lower lobes, can move a lot during respiration; this motion needs to be accounted for during radiotherapy. In cases where 4D CT simulation scans are not performed, the current protocol at our centre is to apply a generic (internal motion + setup) margin of 0·70 cm in the axial plane and 1·20 cm in the longitudinal plane to all lung tumours, regardless of location. We analyse the tumour motions of a cohort of our local patients and categorise them into different locations in the lung. We seek to assess the adequacy of the current margins and to derive a more accurate set of standard margins which are specific for lung tumour locations.Methods:All cases of lung tumours treated with stereotactic ablative radiotherapy between 2012 and 2016 were identified retrospectively and 4D CT scan data analysed. These tumours were grouped into the following locations: upper zone (UZ), middle zone (MZ) and lower zone (LZ). The treatment planning system was used to generate the displacements of the centre of mass of the tumours in the right–left, anterior–posterior and superior–inferior axes; these were compared with the current generic margins. Median displacements were calculated for each axis in each location. New planning target volume (PTV) margins were derived by summing the median displacement, median absolute deviation (MAD) and 0·5 cm (for setup error).Results:Sixty-three cases were eligible for analyses. Motion in the superior–inferior direction was the greatest for all tumour locations, ranging from a median of 0·17 cm (MAD 0·12 cm) in UZ to 0·77 cm (MAD 0·27 cm) in LZ. Median tumour displacements in the anterior–posterior and right–left axes were similar for all locations, <0·30 and 0·20 cm, respectively. The current generic margins were adequate for only one-third of the cases in this study. A new PTV margin of 2·10 cm in the superior–inferior axis may be required for LZ tumours, while an additional 1–2 mm should be added to the current radial margins.Conclusion:The current generic margins are inadequate for the majority of cases. Tumour motion is the greatest in LZ in the superior–inferior axis. Motion mitigation strategies are essential for large LZ tumours.
Genetics of fruit oleoresin and capsaicin contents in chilli inter-species (Capsicum annuum × C. chinense) cross

Published: January 2020

AbstractChoice of the most appropriate breeding method hinges on mode of action of genes controlling expression of target traits. Pungency (capsaicin) and colour (oleoresin) are most important fruit quality traits in chilli. Genetics of fruit quality traits was unravelled using a combination of first and second degree statistics. An additive-dominance model was inadequate to explain the inheritance of fruit yield and quality traits. Magnitude of additive genetic effects [a] and their variances [σ2A] were higher than those of dominance genetic effects [d] and dominance genetic variances [σ2D] suggesting predominance of additive effect genes in the inheritance of both oleoresin and capsaicin contents. These results are discussed in relation to appropriate selection strategy to be followed for genetic improvement of chilli for oleoresin and capsaicin contents.
Pebble accretion onto planets in turbulent discs
Authors: Kley Wilhelm , Picogna Giovanni , Stoll Moritz H. R. 
Published: January 2020

AbstractPlanets form in protoplanetary accretion discs around young protostars. These discs are driven by internal turbulence and the gas flow is not laminar but has stochastic components. For weakly ionised discs the turbulence can be generated purely hydrodynamically through the vertical shear instability (VSI). Embedded particles (dust/pebbles) experience a hydrodynamic drag and drift inward radially and are stirred up vertically by the turbulent motion of the disc. We study the accretion of particles onto a forming planet embedded in a VSI turbulent protoplanetary disc through a series of 3D hydrodynamical simulations for locally isothermal discs with embedded planets in the mass range from 5 to 100 Earth masses (M2295).

Published: January 2020

AbstractStars and planets form from the same material, thus some of their properties are expected to be inter-connected. In order to characterise exoplanets, we need to investigate the planet-hosting stars. Carbon and oxygen are quite abundant and play an important role in stellar interiors by generating energy in thermonuclear reactions. Abundances of C and O may influence water availability on exoplanets. The C/O ratio also controls an amount of carbides and silicates that can be formed. Thus, we are performing a uniform study of C/O ratios in bright stars ( V < mag) located towards the northern ecliptic pole which will be targeted by the TESS and JWST space missions. The first results for a sample of 140 stars analysed are presented.
Formation of S-type planets in close binaries: tidal capture of circumbinary planets
Authors: Ji Jianghui , Gong Yan-Xiang 
Published: January 2020

AbstractIn this work, we proposed a possible mechanism for the formation S-type planet in close binaries (0.5 au < aB < 3 au). Numerical simulations showed that the maximum capture probability is ∼ 10%, which can be comparable to the tidal capture probability of hot Jupiters in single star systems. The capture probability is related to binary configurations. Furthermore, we find that S-type planets with retrograde orbits can be naturally produced via capture process. These planets on retrograde orbits can help us distinguish in situ formation and post-capture origin for S-type planet in close binaries. The forthcoming missions (PLATO or TESS) will provide the opportunity and feasibility to detect such planets.
Water delivery to dry protoplanets by hit-and-run collisions

Published: January 2020

AbstractFinal water inventories of newly formed terrestrial planets are shaped by their collision history. A setting where volatiles are transported from beyond the snowline to habitable-zone planets suggests collisions of very dry with water-rich bodies. By means of smooth particle hydrodynamics (SPH) simulations we study water delivery in scenarios where a dry target is hit by a water-rich projectile, focusing on hit-and-run encounters with two large surviving bodies, which probably comprise about half of all similar-sized collisions (Genda et al. 2017).
Formation of the Earth-Moon system
Authors: Ipatov Sergei I. 
Published: January 2020

AbstractTrans-Neptunian satellite systems and embryos of the Earth-Moon system could be formed as a result of contraction of rarefied condensations. The angular momenta of rarefied condensations needed for such formation could be acquired at collisions of condensations. The angular momentum of the present Earth-Moon system could be acquired at a collision of two rarefied condensations with a total mass not smaller than 0.1ME, where ME is the mass of the Earth. The mass of the condensation that was a parent for the embryos of the Earth and the Moon could be about 0.01ME, if we take into account the growth of the angular momentum of the embryos with growth of their masses. The Moon embryo could get by an order of magnitude more material ejected from the Earth embryo than that fell directly onto the Moon embryo.
