Authors: Hänsli Christof , Lavan Suijana , Pfister Isabel B. , Schild Christin , Garweg Justus G. 
Published: May 2022

Purpose
To find predictive markers for the visual potential in optical coherence tomography (OCT) one month after surgical repair of macula-involving rhegmatogenous retinal detachment (miRD) with and without internal limiting membrane (ILM) peeling.

Methods
This retrospective single-center, single-surgeon cohort study included 74 patients who underwent pars plana vitrectomy (PPV) for primary miRD between January 2013 and August 2020 with follow-up examinations for at least 6 months. Patients developing recurrent detachments, media opacities, or with an axial length over 27 mm were excluded from the analysis. LogMAR visual (VA) and LogRAD reading acuity (RA) ± standard deviation (SD), and OCT measurements 6 months after surgery were compared to OCT and VA measurements one month after surgery using multiple linear regression analysis for predictions.

Results
VA increased from 0.34 ± 0.25 at one month to 0.22 ± 0.21 after 6 months [p < 0.001; effect size = -0.662, 95% confidence interval (CI): -(0.99–0.33)]. The continuity of the external limiting membrane (ELM) and ellipsoid zone (EZ) increased between 1 and 6 months. Subfoveal ELM integrity after one month predicted VA [adjusted R2 of 8.0%, F(2, 71) = 4.17, p = 0.018] and RA [adjusted R2 of 29%, F(2, 27) = 6.81, p = 0.002] after 6 months. EZ integrity had a less pronounced predictive effect on VA and RA. ELM integrity after 1 month correlated with better reading acuity after 6 months (p = 0.016).

Conclusion
VA and morphological OCT parameters improve between 1 and 6 months after surgery for miRD. The grade of ELM is a better predictor for RA than for VA, explaining more variance.

Verification of surface electromyographic activity of the oblique externus abdominis using ultrasound shear wave elastography
Authors: Chino Kentaro , Ando Ryosuke , Suzuki Yasuhiro 
Published: May 2022

AbstractThis study used ultrasound shear wave elastography (SWE) to revalidate whether surface electromyographic (EMG) electrodes placed on the oblique externus abdominis (OE) can detect only the OE activity without the confounding activity of the underlying oblique internus abdominis (OI). During left and right trunk rotations, the EMG activity was acquired using surface EMG electrodes placed on the right OE. Shear wave velocity (Vs) values of the right OE and OI were acquired using SWE. The EMG activity during the left and right trunk rotations significantly increased as the level of exertion increased (25%, 50%, 75%, and 100% of the one‐repetition maximum [1RM]). The Vs of the right OE was significantly different only between 25% and 75% 1RM in the right trunk rotation, but significantly increased from 25% to 75% 1RM during the left trunk rotation. The Vs of the right OI during the right trunk rotation significantly increased with increased levels of exertion, except between 50% and 75% 1RM. The results for the Vs of the OE and OI in the right trunk rotation suggest that surface EMG electrodes placed on the OE would detect not only the antagonistic OE activity but also the agonistic OI activity.

Published: May 2022

Abstract
This paper presents a circular monopole antenna with uniquely packed quad T-shaped strips etched on FR4 epoxy substrate having material permittivity 4.4, loss tangent 0.02, and thickness 1.6 mm. The 3.5 GHz band is achieved through this arrangement, which has return loss less than −10 dB while maintaining VSWR <2. It provides a peak gain of 2.65 dBi at 3.5 GHz and average gain of 2.52 dBi in the entire operating frequency band. The radiation pattern is almost omnidirectional in E plane and bidirectional in H plane. The proposed antenna has a compact size of 41.25 mm × 30.55 mm. The simulated results of S11 parameters, gain, VSWR, radiation pattern, and efficiency are studied and verified with the measured results of fabricated antenna as well as its equivalent lumped circuit model. Investigation shows that the proposed antenna can be employed for WLAN/WiMAX applications efficiently.
Mapping paddy rice and rice phenology with Sentinel-1 SAR time series using a unified dynamic programming framework
Authors: Wang Mo , Wang Jing , Chen Li , Du Zhigang 
Published: May 2022

AbstractMonitoring rice planting areas and their phenological phases is crucial for yield estimation and informed decision-making. This study proposed a unified method for mapping rice field and rice phenology with a dynamic time wrapping (DTW) distance-based classifier and its variant sub-DTW algorithm using Sentinel-1’s synthetic aperture radar (SAR) VH band. Field samplings were conducted for broad landcover types in one of the areas of interest (AOIs). We implemented a pixel-wisek-nearest neighbor classification model with DTW distance to identify paddy rice pixels. Standard rice phenological profiles of the SAR VH band were defined by ground monitoring of a sample rice field. Based on rice planting maps and the standard phenological profiles, rice phenological phases were estimated by pattern matching strategy with the sub-DTW algorithm. Experiments on six counties in Northeast China presented promising results. The overall producer and user accuracy reached 92.9 and 91.9% for rice mapping, respectively. The mean root mean square error (RMSE) for phenology estimation was 3.5 days. Rice planting and rice phenology maps were generated for the six AOIs. The phenological variances of the AOIs implied the effects of climate and rice cultivars on phenological development.

Experimental study and three-dimensional modeling of moisture transport in wood by means of near-infrared hyperspectral imaging coupled with a heat and mass transfer simulation method

Published: May 2022

Abstract
Substantial efforts have been undertaken for visualizing and simulating the characteristics of water movement in wood. However, three-dimensional (3D) thermo-hygric simulations still pose challenges, not only because wood has a heterogeneous microstructure that results in complex computational models but also because there is a lack of proper experimental techniques to support and validate the model constructions. In this study, the moisture distribution in wood during the water adsorption and desorption processes was first visualized using a near-infrared hyperspectral imaging (NIR–HSI) method that has high resolution, sensibility, and stability. Then, based on the moisture visualization results, the main parameters of a mass transfer simulation code were varied. The visualization and simulation results were confirmed to match well with the main characteristics; e.g., drying speed was slower in the wood parts with higher densities. Additionally, there was a relatively large gradient over the surface layer of the wood samples as the drying progressed, whereas this was not an obvious feature in the water adsorption process. Hence, this study proposes that the NIR–HSI method can be combined with thermo-hygric and 3D simulation model construction. Such an approach provides the basis for optimizing drying conditions and providing high-quality wood products.

Published: May 2022

Abstract
In order to accomplish efficient mixing of liquids with large differences in flow rates, an efficient multi-orifice impinging transverse (MOIT) jet mixer is used in this paper. Its structure combines a conventional MOIT jet mixer with a venturi jet mixer to improve the mixing efficiency of the MOIT jet mixer. The flow characteristics and mixing effects inside the conventional and efficient jet mixer are numerically simulated by means of a Multiphase Models. Based on building the experimental platform, the maximum error between the simulation results and the experimental results obtained with the high-speed camera is 8.42%, which verifies that the model and simulation method applies to the simulation of the mixer. In addition, the paper uses MATLAB software to obtain the interphase contact area at the transverse orifice section and verifies that the contact area at the transverse orifice section affects the mixing effect of the mixer. The droplet size distribution was also analyzed by the CFD-PBM model. The results show that the efficient MOIT jet mixer has better mixing efficiency and mixing effect, and the optimal values of the number of orifices and main fluid flow rate of the jet mixer exist. In addition, the mixing effect of the mixer showed a decreasing trend with the increase of the orifice size. The results of this paper complete the optimization of the parameters of the MOIT jet mixer, facilitating its industrial application. And combining two different mixers to create a novel jet mixer, which provides a direction for the development of new jet mixers and helps to promote the development of the fine chemical industry.
Combination of three global Moho density contrast models by a weighted least-squares procedure
Authors: Sjöberg Lars E. , Abrehdary Majid 
Published: May 2022

Abstract
Due to different structures of the Earth’s crust and mantle, there is a significant density contrast at their boundary, the Moho Density Contrast (or shortly MDC). Frequently one assumes that the MDC is about 600 kg/m3, but seismic and gravimetric data show a considerable variation from region to region, and today there are few such studies, and global models are utterly rare.
This research determines a new global model, called MDC21, which is a weighted least-squares combination of three available MDC models, pixel by pixel at a resolution of 1° × 1°. For proper weighting among the models, the study starts by estimating lacking standard errors and (frequently high) correlations among them.
The numerical investigation shows that MDC21 varies from 21 to 504 kg/m3 in ocean areas and ranges from 132 to 629 kg/m3 in continental regions. The global average is 335 kg/m3. The standard errors estimated in ocean regions are mostly less than 40 kg/m3, while for continental regions it grows to 80 kg/m3. Most standard errors are small, but they reach to notable values in some specific regions. The estimated MDCs (as well as Moho depths) at mid-ocean ridges are small but show significant variations and qualities.
When subjects frame the clause: discontinuous noun phrases as an iconic strategy for marking thetic constructions
Authors: Schultze-Berndt Eva 
Published: May 2022

AbstractThis article builds on observations from several research areas which hitherto have been pursued relatively independently of one another, to argue that discontinuous nominal expressions are one of the attested strategies for marking a subtype of sentence focus constructions known as thetic constructions. This analysis can be applied to the type of discontinuity termed extraposition from subject NP/DP in languages with otherwise strongly configurational nominal expressions such as English. For these constructions, however, it cannot be ruled out that weight/length is an alternative or additional motivation. Evidence from several Australian languages, where discontinuous subjects usually just involve a semantic head and a modifier, can be used to show that this strategy is attested even where weight is not a plausible factor. Like other construction types that are associated with theticity crosslinguistically, discontinuous nominal expressions are saliently distinct from topic-comment (“categorical”) constructions and thus obey the principle of detopicalization identified by Lambrecht, Knud. 2000. When subjects behave like objects: An analysis of the merging of S and O in sentence-focus constructions across languages.Studies in Language24(3). 611–682. The findings support the hypothesis that the principle of iconicity of distance, which ensures contiguity of the subconstituents of a phrase under most circumstances, will only be overridden if another principle motivates this violation. Such competing principles include highlighting a contrastive modifier and the distribution of weight, both discussed in previous literature. Here it will be argued that detopicalization can be added to this list since discontinuity prevents the assignment of topic status to the subject expression. Moreover, a construction where a discontinuous subject frames the entire clause is itself iconically motivated by the principle of informational integration which results in the unitary, non-bipartite nature of the construction generally associated with theticity.
Sowjetische Evakuierung und deutscher Rückzug – Evakuierungserfahrungen der Charkiver Bevölkerung im Zweiten Weltkrieg
Authors: Eckl Laura 
Published: May 2022

Zusammenfassung
Die Stadt Charkiv war zu Beginn des Zweiten Weltkriegs ein wichtiger Ballungsraum der sowjetischen Rüstungs‑ und Metallindustrie im Nordosten der Ukrainischen Sozialistischen Sowjetrepublik. Nach dem Angriff der Wehrmacht auf die Sowjetunion am 22. Juni 1941 entwickelte sich die Stadt aufgrund ihrer kriegswichtigen Ressourcen zu einem intensiv umkämpften Standort, der in ständiger Frontnähe mehrmals evakuiert wurde. Dieser Beitrag untersucht zwei der insgesamt vier Evakuierungen bzw. Räumungen der Stadt – zum einen die sowjetische Evakuierungspolitik im Herbst 1941 vor Beginn der deutschen Besatzung und zum anderen die deutsche Räumung im Januar/Februar 1943 vor der kurzzeitigen Rückereroberung durch die Rote Armee. Im Mittelpunkt steht, wie die Charkiver Bevölkerung diese zwei Phasen erlebte, sie sich als Alltagserfahrungen aneignete und in Teilen in Beziehung zueinander setzte. Eine zentrale These des Beitrags ist, dass sich Evakuierungs‑ und Rückzugspraktiken während des Zweiten Weltkriegs inhärent in (Vor‑)Kriegs‑ und Besatzungspraktiken einfügten, sodass auch Evakuierungserfahrungen und Aneignungsprozesse der Bevölkerung untrennbar mit (Vor‑)Kriegs‑ und Besatzungsalltag verknüpft waren.
»Evakuierende« und »Evakuierte«
Authors: Spohr Johannes 
Published: May 2022

Zusammenfassung
Die mobilen Formationen der ukrainischen Hilfspolizei, genannt Schutzmannschaften (kurz Schuma), wurden bereits 1941 nach dem Einmarsch deutscher Truppen in die Ukrainische SSR gebildet. Im Kontext der Kriegswende, die sich im in dieser Studie untersuchten, zivil verwalteten »Generalbezirk Shitomir« ab 1943 immer stärker wahrnehmbar machte, und des Rückzugs der Wehrmacht durch diese Gebiete änderten sich die Aufgaben, die den Schutzmannschaften seitens der Besatzer zugeordnet wurden. Vor allem nahmen Einsätze im Partisanenkampf stark zu, der häufig auch Terror gegen die Zivilbevölkerung beinhaltete. Gleichzeitig schlug sich der allgemeine Trend einer Re-Sowjetisierung bei den Angehörigen der Hilfspolizei nieder, etwa in Form von Meutereien. Sie wurden gleichsam zu Evakuierten wie auch zu Evakuierenden und nahmen teils widersprüchliche Rollen ein, um ihre Überlebenschancen zu erhöhen.
Militärischer Rückzug und konkurrierende Gebietsräumungen
Authors: Zückert Martin 
Published: May 2022

Zusammenfassung
Während des Slowakischen Nationalaufstands begannen deutsche Stellen im Herbst 1944 mit der Evakuierung der Bevölkerung deutscher Nationalität aus der Slowakei. Dieser Vorgang stand im Zusammenhang mit der kriegsbedingten »Rückführung« deutscher Bevölkerungsgruppen aus Ost‑ und Südosteuropa. Teilweise parallel dazu versuchten slowakische Stellen, die Zivilbevölkerung, Behörden und weitere Einrichtungen vor der sich nähernden Front in Sicherheit zu bringen. Beide Evakuierungen fanden vor dem Hintergrund des Rückzugs der deutschen Wehrmacht statt, das Geschehen wurde in der Forschung jedoch bisher nicht in einem größeren Zusammenhang betrachtet. Der vorliegende Beitrag untersucht die Wechselwirkungen zwischen militärischem Rückzug und der Evakuierung der Zivilbevölkerung. Analysiert wird in diesem Zusammenhang auch, wie die nationalsozialistische »Volkstumspolitik«, aber auch die Praktiken der Verfolgung in dieser Phase weiterwirkten bzw. sich nochmals dynamisierten.
Evakuierungs‑ und Kriegsschauplatz Mark Brandenburg
Authors: Fubel Janine 
Published: May 2022

Zusammenfassung
Die Berlin ummantelnde Region Brandenburg stellte 1945 den wichtigsten Kriegsschauplatz zu Ende des Zweiten Weltkrieges in Europa dar. Ende Januar 1945 war es sowjetischen Einheiten gelungen, auf breiter Front in die Region und damit auch im Mittelabschnitt der Ostfront in das Gebiet des »Altreiches« einzudringen und bis an die Oder vorzurücken. Damit befanden sie sich keine 100 Kilometer mehr von der deutschen Reichshauptstadt entfernt. An einigen Stellen war es ihnen zudem gelungen, auf das Westufer des Flusses zu setzen und erste Brückenköpfe einzurichten. Im Rahmen des Beitrages werden die östlichen Kreise der Region als Kriegs‑ und Evakuierungsschauplatz untersucht. Die deutschen Evakuierungsmaßnahmen waren hier einerseits dadurch gekennzeichnet, dass Verbote und zu spät angeordnete Räumungsbefehle für die Zivilbevölkerung ausgegeben wurden, während Gefangene westwärts verschleppt oder noch vor Ort ermordet wurden, als sich die gegnerische Front den dort befindlichen Haftstätten und NS-Zwangslagern näherte. Im Mittelpunkt des Beitrags steht die Untersuchung, welche Praktiken freigesetzt wurden, als die Kriegsfront auf die »innere« Front zu treffen drohte und sich tatsächlich räumlich mit ihr überlagerte. Zentrale These ist, dass sowohl im Hinblick auf den Einsatz seiner Akteure als auch auf das zum Einsatz kommende (Gewalt‑)Wissen der deutsche Vernichtungskrieg – als Holocaust »vor Ort« und Evakuierungskrieg gegen bestimmte Personengruppen geführt – 1945 in der Mark Brandenburg Fortsetzung gefunden hatte.
Buckling behavior of laminated composites with embedded delaminations
Authors: Deniz Mehmet Emin , Oral Nevra 
Published: May 2022

Abstract
The aim of this study is to determine the structural effects of different delamination types on buckling behavior of the E-glass/epoxy with [0]8, [90]8, [±45]4 orientation angles and aramid/epoxy with [±45]4 orientation angle of the composite plates. The buckling behaviors of the layered composites with three different artificial delamination geometries namely, RECDel (rectangular delamination), SQRDel (square delamination), and CIRDel (circle delamination) as well as with different delamination locations (at depth ratios of t/h = 0.25 and t/h = 0.5) were investigated under compression load experimentally. The boundary conditions were clamped for loaded ends while they were freed for the other edges. The dimensions of rectangular composite plates were selected as 150 mm (L) × 25 mm (b) × 2.32 mm (h). Five specimens for each parameter of delaminated composite plates were tested to get the average buckling load. The test results showed that load values of the aramid/epoxy load values were higher than load values of the glass/epoxy load values regardless of the similarity of the buckling loads for t/h = 0.25 and t/h = 0.5 depth ratios. Furthermore, it is possible to conclude that the performance of both the glass/epoxy and the aramid/epoxy buckling are strongly influenced by the layered orientation configurations.
Effects of coating, holding force, stretching height, yield stress, and surface roughness on springback of steel in the V-stretch bending test

Published: May 2022

Abstract
Various types of defects can impact the mechanical or aesthetic properties of stamped sheets, and the phenomenon of springback (SB) is one of them. SB is complicated, and it is hard to simulate it precisely because it is related to many factors such as tooling geometry, material properties, friction, and boundary conditions. In this article, the SB of V-stretch bended samples with uncoated and coated steel is experimentally and numerically investigated. The steel samples are coated with a thin layer of several metals (zinc, tin, nickel, and chromium). This investigation takes into account the influence of various parameters such as the coating thickness, its roughness, the punch depth, the blank holding force (BHF), and the change in the material’s yield strength. A self-developed two-dimensional elastoplastic finite element code was developed using Abaqus/standard. In this work, we also show that the SB angle is smaller for uncoated sheet, higher BHF, higher surface roughness, lower coating thickness, lower stretching height, and lower yield strength.
Experimental and dynamic thermal numerical investigation of a climate test chamber

Published: May 2022

Abstract
In order to investigate the effects of environmental conditions on materials, industrial products or to meet long warranty periods of the products, various tests are performed in the climate test chambers. They have a multidisciplinary structure and should be designed according to different operating conditions. So obtaining the mathematical model of them and knowing the performance of dynamic behavior are significant both in the design phase and in the control of the designed system. In this study, a novel model is developed for numerical investigation of heating process of prototype climatic test due to the mentioned needs. A so-called temperature-dependent L-section line approach was developed. The insulation material was divided into seven segments. The thermal conduction coefficients of the insulation material, mass flow rate, and specific heat of the air were modeled as a function of temperature, as distinct from constant-coefficient lumped-parameter approaches. The simulation results were compared with the experimental results for different conditions, it was observed that the presented approach was compatible with the experimental results. This developed model is not only limited to climate test chambers, but can also be applied to different engineering disciplines such as control, energy, heat and mass transfer, building, and construction.
