Electromagnetic characterization of transparent conducting thin films using two‐port flange coaxial probe and thin‐film transfer matrix method
Authors: Sadat Saeid , Shokooh‐Saremi Mehrdad , Mirsalehi Mir Mojtaba 
Published: February 2021

AbstractAn efficient method to determine the electromagnetic characteristics of transparent conducting oxide (TCO) thin films is presented herein. When a two‐port flange coaxial probe is used for electromagnetic characterization, it is important to note that since the thickness of the film is very thin, it should be taken into account that the measured S parameters not only correspond to the thin film, but also to the substrate. The main idea of this study is to exploit the S parameters corresponding solely to the thin film by employing transfer matrix method. Then, by using the obtained S parameters, the effective conductivity (σ) and relative permittivity (εr) of the TCO thin film are determined. By applying this method to a sample under test, the conductivity and relative permittivity are obtained in the order of 105 (S/m) and 106 in the 2–20 GHz frequency range, respectively. These results are compared with those obtained by the Nicolson–Ross–Wier and open‐ended coaxial probe methods. Simulation results show that when the TCO thin film thickness reaches 0.5 mm, its conductivity increases up to two times. Also, when the gap between the coaxial probe and the thin‐film surface is 0.1 mm, the conductivity approaches zero. Using this method, the material and thickness of the substrate have slight effect on determining the electromagnetic characteristics.
Flaw characterization in conductive media based on pulsed Eddy current measurements: A fast non‐iterative inversion approach
Authors: Miorelli Roberto , Skarlatos Anastassios , Reboud Christophe 
Published: February 2021

AbstractThis paper proposes a non‐iterative procedure for flaw(s) characterization based on Pulsed Eddy Current Testing (PECT) signals analysis. The adopted inversion strategy is based on the use of supervised statistical learning algorithms. A numerical forward solver, based on the Finite Integration Technique (FIT), is used for the generation of the training data (the input‐targets couples of the learning algorithm). Predictions are then carried out in almost real‐time using a non‐linear kernel based regression method, known as kernel ridge regression. It turns out that the direct fit of the regression model to the raw PECT signals may lead to poor prediction accuracy due to the large cardinality of PECT signals. To remedy this problem, an adaptive sampling strategy has been adopted in this work. The performance of the proposed methodology is discussed and compared with solutions proposed in the literature.

Published: February 2021

Aims. Cosmic-ray-induced sputtering is one of the important desorption mechanisms at work in astrophysical environments. The chemical evolution observed in high-density regions, from dense clouds to protoplanetary disks, and the release of species condensed on dust grains, is one key parameter to be taken into account in interpretations of both observations and models.
Methods. This study is part of an ongoing systematic experimental determination of the parameters to consider in astrophysical cosmic ray sputtering. As was already done for water ice, we investigated the sputtering yield as a function of ice mantle thickness for the two next most abundant species of ice mantles, carbon monoxide and carbon dioxide, which were exposed to several ion beams to explore the dependence with deposited energy.
Results. These ice sputtering yields are constant for thick films. It decreases rapidly for thin ice films when reaching the impinging ion sputtering desorption depth. An ice mantle thickness dependence constraint can be implemented in the astrophysical modelling of the sputtering process, in particular close to the onset of ice mantle formation at low visual extinctions.

Zusammenfassung
Hintergrund Das Vorliegen von leichten kognitiven Störungen bei der
Parkinson Erkrankung ist aktuell der beste Prädiktor für die
Entwicklung einer Demenz bei Morbus Parkinson. Expertengruppen der Movement
Disorder Society haben für die Diagnose leichter
kognitiveStörungen und Parkinson Demenz standardisierte diagnostische
Verfahren vorgeschlagen. Diese können aufgrund fehlender
Übersetzungen oder geeigneter Normen nicht ohne weiteres auf den
deutschsprachigen Raum angewendet werden.
Fragestellung Entwicklung evidenzbasierter Empfehlungen zur
deutschsprachigen neuropsychologischen Diagnostik bei Morbus Parkinson.
Methode Anhand einer ersten systematischen Literaturrecherche wurden
Empfehlungen (Konsensuskriterien, Guidelines und Reviews) zur
neuropsychologischen Diagnostik zusammengetragen. In einer zweiten
Literaturrecherche wurden normierte neuropsychologische Testverfahren in
deutschsprachigen Studien identifiziert. Berechnet wurde die
Effektstärke dieser Tests zur Diskrimination zwischen Gesunden und
Parkinson-Patienten bzw. Parkinson-Patienten mit verschiedenen kognitiven
Diagnosen (ohne kognitive Störungen, mit leichten kognitiven
Störungen und mit Demenz).
Ergebnisse Nach Volltextsuche wurden 48 neuropsychologische Tests aus 127
Artikeln zu Testempfehlungen extrahiert. In der zweiten Literaturrecherche
wurden aus 1716 Artikeln final 23 in das Review aufgenommen. Die
höchsten Effektstärken zur Diskrimination der
neuropsychologischen Leistung von Gesunden und Parkinson-Patienten wurden
für Tests in den Domänen Exekutivfunktionen, Aufmerksamkeit und
visuell-kognitive Leistungen ermittelt. Testempfehlungen der Autoren basieren
auf den Ergebnissen beider Literaturrecherchen und ermöglichen eine

Does Nutrition Affect Endometriosis?
Authors: Helbig Martina , Vesper Anne-Sophie , Beyer Ines , Fehm Tanja 
Published: February 2021

AbstractEndometriosis is a hormone-related, chronic inflammation in women of childbearing age. The aetiology and pathogenesis of endometriosis are not yet fully understood. For other illnesses classed as lifestyle diseases, the link between nutrition and pathogenesis has already been researched and proven. With regard to these findings, the question continues to arise as to whether and how a specific diet and lifestyle could also influence pathogenesis and the progression of endometriosis. The aim of this review is to examine the data and determine what influence nutrition has on the development of endometriosis or on existing disease. The study results currently available do not permit a clear, scientific recommendation or indicate a detailed diet. In summary, it can be said that fish oil capsules in combination with vitamin B12 have been associated with a positive effect on endometriosis symptoms (particularly of dysmenorrhoea). Alcohol and increased consumption of
red meat and trans fats are associated with a negative effect. The results of the studies listed with regard to fruit and vegetables, dairy products, unsaturated fats, fibre, soy products and coffee are not clear. Therefore, the general recommendations for a balanced and varied diet in line with the guidelines of the Deutsche Gesellschaft für Ernährung e. V. [German Nutrition Society] apply, along with the recommendation to cut out alcohol. In order to be able to derive more concrete recommendations, we require further studies to investigate the influence of nutrition on endometriosis.

Abstract
Purpose To evaluate perioperative outcomes and the prognostic role of the tramline sign in a cohort of women with anterior placenta previa.
Materials and Methods Retrospective analysis of 3D ultrasound volumes from women with anterior placenta previa who underwent ultrasound examination beyond 32 weeks. 3D and 3D color volumes were obtained from a sagittal section of the uterus bisecting a partially full bladder and processed using Crystal Vue and Crystal Vue Flow rendering to look for the “tramline sign”. “Partial obliteration” was defined as a loss of some or part of the uterine-serosal interface and “full obliteration” as when both interfaces were interrupted. Postnatal ascertainment of placenta accreta spectrum (PAS) was confirmed by findings recorded intraoperatively or on a pathology report.
Results 65 cases were included. The tramline sign was “partially” (17) or “fully” (19) obliterated in 36 cases (55.4 %), and present in 29 (44.6 %). Obliteration was associated with earlier gestational age at delivery (35 + 1 (26 + 3–38 + 3) vs. 36 + 4 (25 + 3–38 + 0) weeks, p = 0.005), greater estimated blood loss (800 (400–11 000) vs. 600 (300–2100) mls, p = 0.003), longer operative time (155 (60–240) vs. 54 (25–80) minutes, p < 0.001), higher rate of hysterectomy (97.2 % vs. 0.0 %, p < 0.001), longer postoperative admission (7 (3–19) vs. 3 (1–5) days, p < 0.001) and a 100 % rate of postnatal diagnosis of PAS. The finding of an “obliterated” tramline sign identified all women that required hysterectomy and all cases of PAS.
Conclusion A “partially or fully obliterated” tramline sign is strongly associated with indicators of operative complexity, the postnatal confirmation of PAS, and the need for peripartum hysterectomy.

Zusammenfassung
Hintergrund Der Morbus Pompe ist eine lysosomale Multisystemerkrankung mit
prädominanter Myopathie, für die eine Enzymersatztherapie (EET) mit rekombinanter
α-Glucosidase verfügbar ist. Diese muss aktuell zweiwöchentlich lebenslang erfolgen. Um
die Belastung durch diese Behandlungsform gering zu halten, besteht bei vielen Betroffenen
der Wunsch, die EET zu Hause als sog. Heiminfusionstherapie durchzuführen.
Ziele und Methoden Im Rahmen zweier Deutsch-Österreichisch-Schweizerischer
Konsensus-Expertentreffen in den Jahren 2019 und 2020 wurde diskutiert, welche
Voraussetzungen gegeben sein müssen, damit eine Heiminfusionstherapie medizinisch
vertretbar erfolgen kann, wie diese sachgemäß durchzuführen ist und wie die Rechtslage für
delegierende Ärzte aussieht.
Ergebnisse und Diskussion Prinzipiell ist bei Patienten mit Morbus Pompe eine
Heiminfusionstherapie möglich, wenn bestimmte Voraussetzungen erfüllt sind. Die
Entscheidung muss für jeden Patienten individuell getroffen werden. Der behandelnde Arzt
delegiert die Durchführung der Heiminfusionstherapie ad personam an eine
Pflegekraft. Die Endverantwortung für die korrekte Durchführung der EET verbleibt aber
beim Arzt. Die Heiminfusionstherapie muss durch speziell geschultes Pflegepersonal
erfolgen. Hauptrisiko ist das Auftreten allergischer Reaktionen. Deren adäquate
Erstbehandlung muss ebenso sichergestellt sein wie die Verfügbarkeit einer
notfallmedizinischen Versorgung. Um die psychosoziale Belastung von Patienten mit Morbus
Pompe in deutschsprachigen Ländern zu minimieren und delegierenden Ärzten größere
Rechtssicherheit zu geben, sind klarere Regelungen für die Durchführung einer
Heiminfusionstherapie wünschenswert.
Access to Highly Substituted Pyrimidine N-Oxides and 4-Acetoxymethyl-Substituted Pyrimidines via the LANCA Three-Component Reaction–Cyclocondensation Sequence

Published: February 2021

AbstractThe LANCA three-component reaction of lithiated alkoxy­allenes (LA), nitriles (N), and carboxylic acids (CA) smoothly provides β-alkoxy-β-ketoenamides in broad structural variety. The subsequent cyclocondensation of these compounds with hydroxylamine hydrochloride afforded a large library of pyrimidine N-oxides under mild conditions and in good yields. Their synthetic utility was further increased by the Boekelheide rearrangement leading to 4-acetoxymethyl-substituted pyrimidines. With trifluoroacetic anhydride the rearrangement proceeds even at room temperature and directly furnishes 4-hydroxymethyl-substituted pyrimidine derivatives. The key reactions are very robust and work well even in the presence of sterically demanding substituents.
Reconstruction of a Severely Damaged Cartilaginous Septum with a Bypass L-Strut Graft using Costal Cartilage
Authors: Choi Woo Ri , Jang Yong Ju 
Published: February 2021

Abstract
Objective Reconstruction of a weakened septal cartilage is a key procedure for the correction of deformed noses. However, when septal mucoperichondrium dissection is technically challenging, reconstruction of the lower two-thirds of the nose should be performed bypassing the damaged septal cartilage and mucosa. This article summarizes our experience with treating patients with severely damaged septal cartilage with bypass L-strut graft using costal cartilage.
Methods We retrospectively reviewed 26 patients who underwent rhinoplasty using bypass L-strut graft. Autologous costal cartilage was used for creating L-strut in two different ways: (1) by fashioning the L-shaped graft as one unit using the sixth rib cartilage and (2) by integrating a dorsal strut with a columellar strut using slices of the seventh rib cartilage. The caudal strut is fixated to the anterior nasal spine; the dorsal L-strut is placed on the nasal dorsum with no fixation to the nasal bone. Medical records were assessed for demographic, clinical, and treatment information.
Results One-piece-type L-strut graft was used for 11 patients and integrated-type L-strut graft was used for 15 patients. No statistical differences were found in postoperative aesthetic outcomes between the two groups. The postoperative assessment of surgical outcomes was excellent in 10 patients, good in 10, fair in 6, and poor in none. Functionally, all 26 patients experienced improvements in nasal breathing.
Conclusion Bypass L-strut graft using costal cartilage is a useful surgical maneuver of septal reconstruction in particular nasal deformity when the creation of the septal mucoperichondrial pocket is difficult or better to be avoided.

Published: February 2021

AbstractChildren’s diets can have major implications for a wide range of diseases and their development outcomes. In Africa, micronutrient deficiency remains a major challenge and affects the health and development of vulnerable populations, especially children. A major effort to combat micronutrient deficiency has targeted biofortification of staple foods, with greatest potential being registered in the enrichment of, among others, sweetpotato with beta carotene—a precursor for vitamin A. However, overcoming vitamin A deficiency is made all the more complicated by children’s general resistance to unfamiliar foods. We report the results of a field experiment in Nigerian schools designed to use behavioral techniques to promote consumption of an unfamiliar food: the pro-vitamin A rich orange-fleshed sweetpotato. We find that children eat more, on average, when the sweetpotato is introduced alongside behavioral nudges such as songs or association with aspirational figures. These results appear to conform to results found in a developed country context.
Experiencing and supporting institutional regionalization in Belgium: a normative and interpretive policy feedback perspective
Authors: Verhaegen Soetkin , Dupuy Claire , Van Ingelgom Virginie 
Published: February 2021

AbstractRegionalization has been a defining feature of European politics since the 1970s. Previous work has studied political drivers of the movements of competences to the subnational level, including the role of citizens’ preferences. Yet, we still know little about how these new divisions of competences between government levels have impacted the development of public opinion about this division. The article builds on the literature on policy feedback and argues that institutional regionalization may both directly and indirectly affect support for regionalization through normative and interpretive effects. To empirically qualify these expectations, the article uses eight cross sections of the Flemish and Walloon populations in Belgium (1991–2019). This approach explains differences in support for regionalization between citizens that were socialized in different institutional and regional contexts. The analyses show that Walloons who came of age in the context of more institutional regionalization tend to be more supportive of regionalization. In Flanders, in contrast, support for regionalization is most consistently and substantially explained by regional and Belgian identification. However, our analyses show no support for the expectation that coming of age in a more regionalized Belgium is associated with a greater sense of regional identification.
Hematite reconstruction of Late Triassic hydroclimate over the Colorado Plateau
Authors: Lepre Christopher J. , Olsen Paul E. 
Published: February 2021

Significance
Hematite provides much of the color for the classic Triassic–Jurassic “red beds” of North America and elsewhere. Measuring the spectrum of visible light reflected and absorbed by the red beds, we demonstrate that the hematite concentrations faithfully track 14.5 million years of Late Triassic monsoonal rainfall over the Colorado Plateau of Arizona and use this information to assess interrelationships between environmental perturbations, climate, and the evolution of terrestrial vertebrates. The research challenges conventional ideas that the hematite has limited use for interpreting the ancient past because it is a product of natural chemical alterations that occurred long after the beds were initially deposited.

Published: February 2021

Abstract
In this paper the influence of the deformation of the shapers of various stiffness on the vibration characteristics of the impact is estimated. In particular, the influence of the deformation on the high-frequency vibrations that appears during the operation of the shapers is also estimated. Both analytical and experimental results of measuring of deformation of shapers are presented. The structure of the model of the shock testing machine developed in Peter the Great St. Petersburg Polytechnic University is described in details. An algorithm for the analysis of vibration characteristics obtained during the tests on the model of an impact machine is presented. The results of studies of the characteristics of the materials which the shock pulse shapers are made of are presented. The life of the shapers made of various materials is estimated. Analytic and experimental dependences of the shaper deformation on the lifting height of the shock table are presented. Conclusions about the effect of shaper deformation on impact parameters are drawn.

Published: February 2021

Abstract
According to the study, the authors have calculated and determined the reasonable size of hydraulic prop support of self-advancing hydraulic roof support, used in underground coal mining in the Quang Ninh area. The study took into account various factors that are related to the geological conditions of the mine areas, the manufacturing materials, and mining technology. The results obtained from the study can be reasonably applied to calculate the suitable size of the hydraulic prop support based on the durability and stability required for coal mines with similar geological conditions as the Quang Ninh mines. The study was carried out with the aim of improving the efficiency of using hydraulic prop support and reducing product costs. In addition, the research results can be the basis for calculating other types of hydraulic prop support used as a reference for manufacturing other underground coal mining supports at Quang Ninh coal basin.
