Published: February 2020

Abstract
Background Endovascular stent grafting has emerged as an option to treat traumatic aorta injuries with reported significantly low mortality and morbidity. Stent collapse is one of the complications that can occur in this type of treatment. The aim of this article is to analyze the expected cause of stent collapse and to draw attention to the importance of the surveillance follow-up, as this phenomenon may occur late postdeployment.
Methods A retrospectively collected dataset from the two highest volume trauma centers in Saudi Arabia was analyzed between April 2007 and October 2012. A total of 66 patients received stent grafts for traumatic aortic injury and were included in the study. We apply Ishimaru's anatomical aortic arch zones and Benjamin's aortic injury grading systems. There were 35 patients with aortic injury at zone 2, 26 patients in zone 3, and 5 patients in zone 4. About 96% (63) of the injuries were grades 2 and 3, including large intimal flap or aortic wall pseudoaneurysm with change in wall contour. The technical success rate, as defined by complete exclusion of lesions without leaks, stroke, arm ischemia or stent-related complications, was 90%.
Results Proximal stent collapse occurred in 4.5% of patients (3 of 66 inserted stents) during follow-up of 4 to 8 years (mean, 6 years). Patients with stent collapse tended to have an acute aortic arch angle with long-intraluminal stent lip, when compared with patients with noncollapsed stents. Intraluminal lip protrusion more than 10-mm increased collapse (p < 0.001). Stent-grafts sizes larger than 28 mm also demonstrated a higher collapse rate (p < 0.001).
Conclusions The risk of stent collapse appears related to poor apposition of the stent due to severe aortic arch angulation in young patients and to large stent sizes (>28 mm). Such age groups may have more anatomical and aortic size changes during the growth. Clinical and radiological surveillance is essential in follow-up after stent-graft treatment for traumatic aortic injury.

Abstract
Objectives Visual dysfunction in patients with pituitary adenomas is a clear indication for endoscopic endonasal transsphenoidal surgery (EETS). However, the visual outcomes vary greatly among patients and it remains unclear what tumor, patient, and surgical characteristics contribute to postoperative visual outcomes.
Methods One hundred patients with pituitary adenomas who underwent EETS between January 2011 and June 2015 in a single institution were retrospectively reviewed. General patient characteristics, pre- and postoperative visual status, clinical presentation, tumor characteristics, hormone production, radiological features, and procedural characteristics were evaluated for association with presenting visual signs and visual outcomes postoperatively. Suprasellar tumor extension (SSE) was graded 0 to 4 following a grading system as formulated by Fujimoto et al.
Results Sixty-six (66/100) of all patients showed visual field defects (VFD) at the time of surgery, of whom 18% (12/66) were asymptomatic. VFD improved in 35 (35%) patients and worsened in 4 (4%) patients postoperatively. Mean visual acuity (VA) improved from 0.67 preoperatively to 0.84 postoperatively (p = 0.04). Nonfunctioning pituitary adenomas (NFPAs) and Fujimoto grade were independent predictors of preoperative VFD in the entire cohort (p = 0.02 and p < 0.01 respectively). A higher grade of SSE was the only factor independently associated with postoperative improvement of VFD (p = 0.03). NFPA and Fujimoto grade 3 were independent predictors of VA improvement (both p = 0.04).
Conclusion EETS significantly improved both VA and VFD for most patients, although a few patients showed deterioration of visual deficits postoperatively. Higher degrees of SSE and NFPA were independent predictors of favorable visual outcomes.
Animal-related concepts across languages and cultures from a cognitive linguistic perspective
Authors: Belkhir Sadia 
Published: February 2020

AbstractThis paper investigates the use of animal-related concepts in the proverbs of English, French, Arabic, and Kabyle. Research in cognitive linguistics has highlighted the important role played by cultural influences in conceptual metaphor variation (Kövecses 2005). Animal-related proverbs constitute interesting examples of cultural influences upon conceptual metaphor and its instantiation in language (Belkhir 2014,2012). The principle of hierarchy underlying the Great Chain Metaphor Theory has been questioned. It has been demonstrated that in addition to the ranking ofhumanandanimalconcepts on a hierarchical scale,animalconcepts were also ranked on the scale (Belkhir 2014). The present article attempts to show that there exists another type of ranking that seems to have never been explored to date; that is, the ranking of concepts within the same animal species. Therefore, this paper offers a cross-cultural cognitive study of some animal-related concepts’ use in a sample of English, French, Arabic, and Kabyle proverbs. Its aim is to explore the influence of cultural contexts and cultural models upon the main meaning foci characterizing the conceptsdog, lion,ass, horse, camel,andoxleading to, not only a hierarchical classification of these animals, but to a classification of animals within one animal species as a result of the influences of cultural contexts and cultural models. The conclusion is that sociocultural contexts determine the main meaning foci characterizing the animal source domain concepts involved in thehuman is animalmetaphor resulting in animal-animal rankings within different species, and animal-animal rankings within the same species.
An integrated study of visual metaphors in Chinese editorial cartoons
Authors: Niu Peipei 
Published: February 2020

AbstractConceptual metaphor theory highlights that metaphor is a matter of thinking. This assumption indicates that metaphors exist not only in language, but also in other modes. This study examines uses of visual and visual-verbal metaphors in 50 Chinese editorial cartoons conceptualizing serious haze problem, with the intention of eliciting implicit meaning conveyed by visual signs alone or together with verbal texts. Both conceptual and critical discourse analysis of the metaphors are conducted. The study finds that the way a metaphor is realized visually and verbally in a cartoon determines the features mapped onto the topic, and further implicitly expresses a critical stance toward the topic under discussion. The metaphors in the cartoons evoke a general understanding of haze problem by activating the war scenario and familiar cultural or social context in viewers. It is found in this corpus that visual fusion and visual replacement are the most frequent kinds of visual metaphors. The study further affirms that visual metaphors are better in conveying rich and implicit conceptual and affective meaning, and can be direct manifestation of the conceptual metaphor without the mediation of language. In sum the study suggests the need for an integrated approach to visual metaphoric representation in multimodal analysis.
Identification of a multi-component berberine 11-hydroxylase from Burkholderia sp. strain CJ1

Published: February 2020

ABSTRACT
Berberine (BBR) is a protoberberine alkaloid extracted from plants such as Coptis japonica (Ranunculaceae). In a previous report, we demonstrated the existence of a 11-hydroxylation pathway employed by BBR-utilizing bacteria for metabolism of BBR. In the present study, we report the identification of the genes brhA, brhB, and brhC as encoding a multicomponent BBR 11-hydroxylase in Burkholderia sp. strain CJ1. BrhA is belonging to the Rieske non-heme iron oxygenase (RO) family, a class of enzymes known to catalyze the first step in bacterial aromatic-ring hydroxylation. We further demonstrate that BrhA activity requires BrhB (ferredoxin reductase) and BrhC (ferredoxin) as electron transport chain components. A BLAST search revealed that BrhA exhibits 38% and 33% sequence identity to dicamba O-demethylase (DdmC; AY786443) and chloroacetanilide herbicides N-dealkylase (CndA; KJ461679), respectively. To our knowledge, this work represents the first report of a bacterial oxygenase catalyzing the metabolism of a polycyclic aromatic-ring alkaloid.

Published: February 2020

ABSTRACT
Although sweet pea (Lathyrus odoratus) beans contain toxic β-aminopropionitrile, the plant itself is readily attacked by insects and is, therefore, protected through the use of pesticides. Consequently, the induction of L. odoratus resistance to insect attack via exogenous treatment is promising for pest control development. Screening of inducible elicitor effects showed that treatment of sweet pea foliage with jasmonic acid (JA) can induce antifeeding-based resistance to tobacco cutworm (Spodoptera litura) larvae. Spectroscopic analysis identified 2-cyanoethyl-isoxazolin-5-one (2-CEIX) as the antifeedant with a half-maximal effective concentration of 33.6 µmol/g fr. wt., i.e., exogenous JA treatment induced antifeeding activity due to the accumulation of 2-CEIX. Moreover, 2-CEIX-induced mortality of S. litura larvae was evaluated by a dipping test and the half-maximal lethal dose was determined to be 5.9 mg/mL. Therefore, 2-CEIX was concluded to be a suitable induced resistance target for elicitors or a lead compound for insecticide development.

, emphasis is put on the roles of the one pion exchange interaction between them and their coupling to intrinsic quark states. Thus hadronic molecules emerge as admixtures of the dominant long-range hadron structure and short-range quark structure. For the pion exchange interaction, properties of the tensor force are analyzed in detail. More coupled channels supply more attractions, and heavier constituents suppress kinetic energies, providing more chances to form hadronic molecules of heavy hadrons. Throughout this article, we show details of basic ideas and methods.

Abstract
At Legnaro National Laboratories of INFN is under construction a Rare Isotope Facility called “Selective Production of Exotic Species” (SPES) based on a 35-70 MeV proton cyclotron, able to deliver two beams with a total current up to 0.75 mA, an ISOL fission target station and an existing ALPI superconducting accelerator as a post accelerator (up to 10 MeV/u for A/q=7). The paper will cover notably: the high-resolution mass separator, the CW RFQ (80 MHz, 727 keV/u, with internal bunching), the 1+ low energy transfer line and the injection line from Charge Breeder to ALPI under installation.
New method to design magnetic channels with 2D optimization tools and using permendur vanadium
Authors: Neri L. , Calabretta L. , Rifuggiato D. , Karamyshev O. 
Published: February 2020

Abstract
Magnetic channels are used in almost all cyclotrons to focus radially the beam along the extraction path through the coils and yoke region, where the rapid fall off of the magnetic field produces a strong vertical focusing and radial defocusing of the beam. These magnetic channels consist generally of three iron bars. The current sheet approximation has been generally used to evaluate quickly the performance of magnetic channels.
For the new magnetic channels to be used in the upgrade of the LNS-INFN k800 Superconducting Cyclotron, a new method was developed to investigate complex configurations and to achieve higher magnetic gradients in a larger area. The optimization procedure is based on a genetic algorithm implemented on MATLAB code and using the COMSOL code to perform the 2D magnetic field simulations.
Moreover, the use of permendur vanadium in alternative to iron allows to reduce the volume of the bars and mainly the magnetic force.
The results of our simulations are here presented.

Abstract
The High-Brilliance Neutron Source (HBS) project aims to design a scalable compact accelerator driven neutron source (CANS) which is competitive and cost-efficient. The concept allows one to optimize the whole facility including accelerator, target, moderators and neutron optics to the demands of individual neutron instruments. Particle type, energy, timing, and pulse structure of the accelerator are fully defined by the requirements of a given neutron instrument. In the following, we present the current status of the HBS project.

Published: February 2020

Abstract
The purposes of the SPES (Selective Production of Exotic Species) project at INFN laboratory in Legnaro (Italy) is to study nuclei close to the drip lines. Therefore, a High-Resolution Mass Separator (HRMS) must provide full separation of the ions with a resolution 1/20000, to be sensible to the proton-neutron mass difference in the fission products. SPES HRMS consists of: two 90° magnet dipoles, one electrostatic multipole in between them, six electrostatic quadrupoles, two electrostatic hexapoles and two electrostatic triplets before and after the slits on the object and image point. All these components will be installed on a high voltage platform with a maximum operating voltage of -240 kV. Before entering the HRMS, a 40 keV energy beam go through an RFQ Cooler, designed to have an output energy spread of 1 eV. Mass separation within target resolution is the most critical part: dipoles must provide a magnetic field homogeneity of 4 10−5 throughout beam occupancy (half magnet pole surface), at a field intensity of 0.562 T for the reference ion 132 Sn. Therefore, a very accurate dipole design is mandatory. This contribute will show the studies which lead to a possible dipole design.

Abstract
The diatom algae from sediments of a paleolake serve as records of changes to environments over the last 7500 cal yr. The lagoon lake formed when the sea level approximately corresponded to the present-day position. Evolution of the paleolake was controlled by sea-level oscillations and humidity changes. Eight stages have been distinguished. During a dry episode in 7330–7090 cal yr BP the lake size decreased. The salinity reached maximal values at the Holocene transgression peak. Three stages of a higher salinity are recognized (6750–6500, 6080–5830, 5420–5090 cal yr BP). A severe flood occurred in 6080–6000 cal yr BP. The brackish-water lake existed in ∼5090 cal yr BP and the freshwater lake in ∼4090 cal yr BP. A prolonged phase of decreasing humidity, associated with a weakening of summer monsoons, led to a drop in sedimentation rates in ∼3510 cal yr BP. Peat accumulation started at the Little Ice Age. The lake was transformed into a swamp during drop in precipitations in ∼270 cal yr BP. Presence of marine diatoms typical in bay and deep-water forms are evidence of influence of extreme storms and tsunami. The age of the paleotsunami coincides well with the regional data.
Foraminiferal and dinocyst associations as indicators of the Holocene environmental changes at the Cambridge Strait, Franz Josef Land
Authors: Ivanova E V , Novichkova E A , Kozhanova D A 
Published: February 2020

Abstract
Herein we report the first decadal to centennial–scale resolution data on foraminiferal and dinocyst assemblages from core AMK-5454 collected in the hard-to-reach Cambridge Strait, Franz Josef Land, and on corresponding paleoenvironments over the last 9.2 ka. The dinocyst and foraminiferal assemblages from the core are rather diverse through the Holocene and represented by 24 and 33 taxa, respectively. The most active hydrodynamics and probably Atlantic Water (AW) inflow are suggested by the enhanced values of autotrophic dinocysts and epibenthic species, as well as Melonis barleeanus, from 9.2 to 6.3 cal ka BP. Specific benthic assemblages indicate high-productivity frontal conditions at site location from 6.3 to 4.1 cal ka BP. AW influx from the Franz Victoria Trough to the Cambridge Strait in subsurface to bottom layer, below the very cold Arctic Water and dense sea ice, is documented by enhanced % Cassidulina teretis over the last 4.5 ka.
The Early Holocene vegetation changes in the vicinity of the Gorbunovo peat bog in the Middle Urals (Russia)

Published: February 2020

Abstract
The paper presents the results of a comprehensive palaeobotanical research of lacustrine and peat deposits of archaeological Mesolithic sites discovered at the Gorbunovo peat bog (Middle Urals). Pollen and plant macrofossil data, as well as a biome model were used to describe the vegetation changes in the study area in the Early Holocene. It was found out that in the second half of the Pre-Boreal and the first half of the Boreal periods of the Early Holocene (approximately to 9,800–9,600 cal BP), the vicinity of the Gorbunovo peat bog was dominated by cold deciduous forests. Larch, spruce-larch and birch forests and meadow communities with periglacial elements were widespread. Various aquatic plants could be found in the pond, though it started to turn into swamp. In the second half of the Boreal period (approximately at 9,600–9,500 cal BP), the taiga biome, including pine and birch-pine forests with occurrence of spruce started to prevail. Periglacial communities became degraded. Aggressive water logging led to the formation of a peat bog.

AbstractIntegrated paleogeographic studies have been performed on the loess and soil sequence in the lower reaches of the Orkhon R., northern Mongolia. The samples were taken continuously through the sequence and studied using a broad assortment of field and laboratory analyses. There are five paleosols exposed in the section under study crowned with the present-day soil and separated from each other by loess horizons or proluvial-deluvial deposits. The dating by radiocarbon proved the soil development beginning from the early Holocene. The two lower soils (PS4 and PS5) formed at that interval are noted for the minimum salinity and a considerable content of carbonates. The soils dated to the middle Holocene (PS3 and PS2) contain the least proportion of organic matter and increased salinity, which may be attributed to a dryer climate (even at optimum intervals) than in the early and late Holocene. In common with the present-day soil, the PS1 buried soil is characterized by negligible (or absent) salinity, and a noticeable accumulation of organic matter and carbonates indicative of favorable warm and relatively wet conditions. All the pollen assemblages indicate the dominance of grass vegetation; it may be safely suggested that open meadow and steppe landscapes, occasionally replaced by semi-deserts, prevailed in the considered region during the Holocene.

Abstract
Parameters such as track diameter and microstruture of latent tracks in polycrystalline Si3N4 induced by 710 MeV Bi ions were studied using TEM and XRD techniques, and MD simulation. Experimental results are considered in terms of the framework of a ‘core–shell’ inelastic thermal spike (i-TS) model. The average track radius determined by means of electron microscopy coincides with that deduced from computer modelling and is similar to the track core size predicted by the i-TS model using a boiling criterion. Indirect (XRD) techniques give a larger average latent track radius which is consistent with the integral nature of the signal collected from the probed volume of irradiated material.
