Published: June 2022

AbstractA Linear Oscillating Actuator (LOA) generates bi‐directional electromagnetic (EM) force between two extreme points. A new topology of moving magnet LOA with axial magnetised PMs and a C‐shaped stator core is proposed. On each side of the mover, two chamfered tubular‐shaped core material parts are attached. All the design parameters, such as mover mass and EM force of the LOA, are optimised using parametric analysis via parametric sweep, and the optimum values of the parameters are chosen based on design and performance parameters. The LOA's performance is examined for various input loading values and at different oscillation region positions. For various values of time‐dependent supply, the EM force's oscillating nature is analysed. The effect of resonance analysis on input current, stroke to current ratio, and efficiency are discussed. The proposed LOA is compared to current LOA topologies in terms of design structure and performance parameters. The FEM results are validated using a special experimental setup. The proposed LOA produces feasible results for the compressor in a refrigeration system.

Published: June 2022

AbstractThe multi‐scale characteristic of online car‐hailing traffic volume can reflect the implied distribution pattern, which is crucial for traffic management and even urban planning. Nevertheless, the spatio‐temporal heterogeneity of online car‐hailing traffic volume makes it challenging to analyze its multi‐scale characteristics effectively. Here, a method named multi‐scale characteristic analysis for online car‐hailing traffic volume with quantum walk (MCATV‐QW) is proposed. MCATV‐QW adopts quantum walks to generate multi‐scale probability patterns that online car‐hailing appears at different locations over time. Then stepwise regression is applied to screen the generated multi‐scale probability patterns, to further analyze the multi‐scale characteristic. We validate MCATV‐QW with online car‐hailing traffic volume in the northeast of Chengdu, China. MCATV‐QW not only achieves better simulation performance, but also reveals the distribution pattern that the influence degree of multi‐scale probability patterns weakens from southwest to northeast of study area. MCATV‐QW also reflects the traffic spatial pattern that is dominated by gradual traffic (48%), with both abrupt (26%) and uniform traffic (26%).
Deep learning‐based hybrid model for the behaviour prediction of surrounding vehicles over long‐time periods

Published: June 2022

AbstractAutonomous vehicles need to have the ability to predict the future behaviour of surrounding vehicles, which helps with proper trajectory planning and tracking. Many behaviour prediction methods have limited application because they have a very limited prediction horizon. This paper proposes a deep learning‐based hybrid model for behaviour prediction over long‐time periods, including manoeuvre recognition and a behaviour prediction module. In manoeuvre recognition module, the CNN extracts the social characteristics of the target vehicle and LSTM outputs the manoeuvre probability vector to form a contextual feature vector with the social features. In the behaviour prediction module, LSTM and Attention are based on the contextual feature vector to capture multi‐time step information in the behaviour time window to complete the prediction of the target vehicle behaviour. Real‐car collection and open‐source vehicle trajectory datasets were used for training and testing. The results show that the proposed algorithm could predict vehicle behaviour with an accuracy of 89.73% and an average prediction time of 2.032 s, which has a high engineering application value.
Range profile similarity‐oriented method for radar imaging of moving target under low signal‐to‐noise ratio environment
Authors: Xu Xinbo , Su Fulin , Jin Xinfei , Gao Jianjun 
Published: June 2022

AbstractInverse synthetic aperture radar (ISAR) imaging is an advanced technique for reconstructing high‐resolution images of moving targets. However, noise interference degrades the readability of the ISAR images under low echo signal‐to‐noise ratio (SNR) environments. Furthermore, noise impairs the performance of ISAR motion compensation, which induces severe defocussing. Thus, a novel range profile similarity‐oriented (RAP‐SO) method with a two‐step denoising strategy is presented. First, attributed to the coherence between ISAR range profiles, the coherent weighted template (CWT) is proposed to preliminarily remove the noise in a high‐resolution range profile (HRRP) and restore the range profile similarity impaired by noise. In order to robustly complete range alignment under a low SNR environment, Keystone transform (KT) is utilised. Thereafter, the weighted template is constructed by virtue of coherent integration. The CWT adaptively gives different weights to HRRP signals and noise, which is called coarse denoising. Second, inspired by the similarities of range profiles, the minimum weighted nuclear norm (Min‐WNN) optimisation is proposed to further reduce the residual noise. The coarse denoised HRRPs are rearranged into an approximate low‐rank matrix. Subsequently, rank‐constraint optimisation on the HRRP matrix via minimising the weighted nuclear norm is performed, aiming to efficiently suppress the residual noise. This step is called fine denoising. As a result, ISAR image quality is significantly improved. Comprehensive experiments illustrate the effectiveness and superiority of the presented method.

Published: June 2022

ZusammenfassungDer Methicillin-resistente Staphylococcus aureus ist ein im täglichen Alltag insbesondere für den Bereich der Dermatologie relevanter multiresistenter gram-positiver bakterieller Erreger. Chronische Wunden und atopische Dermatitis sowie der Typ II-Diabetes mellitus spielen hier als Risikofaktoren eine wichtige Rolle. Dieser Übersichtsartikel fokussiert sich neben Ausführungen zu Bedeutung und klinischem Vorkommen auf eine zusammenfassende Darstellung der Hygieneaspekte bei der Behandlung von MRSA-besiedelten oder -infizierten Patienten. Ziel einer solchen Behandlung mit etablierten Hygienekonzepten ist es, eine mögliche Verbreitung des multiresistenten Erregers von einem Patienten auf andere Personen zu verhindern. Werden diese Hygiene-Maßnahmen umgesetzt und gleichzeitig bei einer Infektion eine evidenzbasierte, nach dem Antibiotic-Stewardship ausgerichtete antibiotische Therapie initiiert, sind dies zwei wesentliche Bausteine, um auch weiterhin, wie in den letzten Jahren schon in Nord- und Mitteleuropa beobachtet, rückläufige MRSA-Prävalenzen zu erzielen.

Abstract
Introduction Minimally invasive surgery skill laboratories are indispensable in training, especially for complex procedural skills such as intracorporal suturing and knot tying (ICKT). However, maintaining a laboratory is expensive, and specially trained teachers are in short supply. During the COVID-19 pandemic, in-person instruction has reduced to almost zero, while model learning via video instruction (VID) has become an integral part of medical education. The aim of this study was to compare the learning effectiveness and efficiency of ICKT by laparoscopically inexperienced medical students through video versus direct expert instruction.
Materials and Methods A secondary analysis of two randomized controlled trials was performed. We drew data from students who were trained in ICKT with expert instruction (EXP, n = 30) and from students who were trained via VID, n = 30). A laparoscopic box trainer including laparoscope was used for ICKT. Objective Structured Assessment of Technical Skills (OSATS), knot quality, and total ICKT time were the parameters for the assessment in this study. Proficiency criteria were also defined for these parameters.
Results Students in the EXP group performed significantly better in OSATS-procedure-specific checklist (PSC) and knot quality compared with students in the VID group, with no difference in task time. Of the students who reached the proficiency criteria for OSATS-PSC and knot quality, those in the EXP group required fewer attempts to do so than those in the VID group. Students in both groups improved significantly in all parameters over the first hour of evaluation.
Conclusion For the laparoscopically inexperienced, training in ICKT through expert instruction presents an advantage compared with video-based self-study in the form of faster understanding of the procedure and the associated consistent implementation of good knot quality. Both teaching methods significantly improved participants' ICKT skills.
Radical Cyclization of Ynamides to Nitrogen Heterocycles
Authors: Evano Gwilherm , Zhang Chunyang , Blanchard Nicolas 
Published: June 2022

AbstractAn efficient radical cyclization of suitably functionalized ynamides to nitrogen-containing heterocycles is reported. Upon reaction with tributyltin hydride in the presence of catalytic amounts of AIBN in toluene at 80 °C, a range of ynamides bearing a N-iodopropyl chain could be smoothly cyclized, in a highly regio- and stereoselective manner, to the corresponding 2-arylidenepyrrolidines in good to excellent yields. The exocyclic double bond was in addition shown to be an excellent anchor for further chemical diversification and the generality of this radical cyclization could be highlighted by its extension to the synthesis of other nitrogen heterocycles including piperidines, azepanes, pyrazolidines and hexahydropyridazines.

Published: June 2022

Background Confirming the diagnosis, invasiveness, and disease extent of intraductal papillary mucinous neoplasms (IPMNs) of the pancreas is challenging. The aim of this study was to summarize the literature on the efficacy and safety of peroral pancreatoscopy (POP) in the diagnosis of IPMN, including the impact of pre- and intraoperative POP on the management of IPMN.
Methods The EMBASE, Medline Ovid, Web of Science, Cochrane CENTRAL, and Google Scholar databases were systematically searched for articles. Eligible articles investigated cohorts of patients who underwent POP for (suspected) IPMN.
Results 25 articles were identified and included in this review; with 22 of these reporting on the diagnostic yield of POP in IPMN and 11 reporting on the effect of pre- or intraoperative POP on clinical decision-making. Cannulation and observation rates, and overall diagnostic accuracy were high across all studies. Frequently reported visual characteristics of IPMN were intraductal fish-egg-like lesions, hypervascularity, and granular mucosa. Overall, the adverse event rate was 12 %, primarily consisting of post-endoscopic retrograde cholangiopancreatography pancreatitis, with a pooled rate of 10 %, mostly of mild severity. Regarding the impact of POP on clinical decision-making, POP findings altered the surgical approach in 13 %–62 % of patients.
Conclusion POP is technically successful in the vast majority of patients with (suspected) IPMN, has a consistently high diagnostic accuracy, but an adverse event rate of 12 %. Data on intraoperative pancreatoscopy are scarce, but small studies suggest its use can alter surgical management. Future studies are needed to better define the role of POP in the diagnostic work-up of IPMN.

Published: June 2022

Objective We sought to (1) use the Robson 10-Group Classification System (TGCS), which classifies deliveries into 10 mutually exclusive groups, to characterize the groups that are primary contributors to cesarean delivery frequencies, (2) describe inter-hospital variations in cesarean delivery frequencies, and (3) evaluate the contribution of patient characteristics by TGCS group to hospital variation in cesarean delivery frequencies.
Study Design This was a secondary analysis of an observational cohort of 115,502 deliveries from 25 hospitals between 2008 and 2011. The TGCS was applied to the cohort and each hospital. We identified and compared the TGCS groups with the greatest relative contributions to cohort and hospital cesarean delivery frequencies. We assessed variation in hospital cesarean deliveries attributable to patient characteristics within TGCS groups using hierarchical logistic regression.
Results A total of 115,211 patients were classifiable in the TGCS (99.7%). The cohort cesarean delivery frequency was 31.4% (hospital range: 19.1–39.3%). Term singletons in vertex presentation with a prior cesarean delivery (group 5) were the greatest relative contributor to cohort (34.8%) and hospital cesarean delivery frequencies (median: 33.6%; range: 23.8–45.5%). Nulliparous term singletons in vertex (NTSV) presentation (groups 1 [spontaneous labor] and 2 [induced or absent labor]: 28.9%), term singletons in vertex presentation with a prior cesarean delivery (group 5: 34.8%), and preterm singletons in vertex presentation (group 10: 9.8%) contributed to 73.2% of the relative cesarean delivery frequency for the cohort and were correlated with hospital cesarean delivery frequencies (Spearman's rho = 0.96). Differences in patient characteristics accounted for 34.1% of hospital-level cesarean delivery variation in group 2.
Conclusion The TGCS highlights the contribution of NTSV presentation to cesarean delivery frequencies and the impact of patient characteristics on hospital-level variation in cesarean deliveries among nulliparous patients with induced or absent labor.

Published: June 2022

We present a free-space optical displacement sensor for measuring geological slip event displacements within a laboratory setting. This sensor utilizes a fiberized Mach-Zehnder based optical heterodyne system coupled with a digital phase lock loop, providing a large dynamic range (multiple centimeters), high displacement resolution (with an amplitude spectral density of &lt;10−10 m/Hz for frequencies above 100 Hz), and high velocity tracking capabilities (up to 4.96 m/s). This displacement sensor is used to increase the displacement and the time sensitivity for measuring laboratory-scale earthquakes induced in geological samples by using a triaxial compression apparatus. The sensor architecture provides an improved displacement and time resolution for the millisecond-duration slip events, at high containment and loading pressure and high temperatures. Alternatively, the sensor implementation can be used for other non-contact displacement readouts that required high velocity tracking with low noise and large dynamic range sensing. We use 13 high-velocity slip events in Fontainebleau sandstone to show the large dynamic range displacement tracking ability and displacement amplitude spectral densities to demonstrate the optical readout’s unique sensing capabilities.

Published: June 2022

To solve the problem of the large axial size of high-power microwave (HPM) reflectarray antenna and difficulty in vacuum packaging, a dielectric is introduced in the design of the antenna element. On this basis, a dielectric embedded metasurface reflectarray antenna (DEMRA) with high power handling capacity and wide-range beam scanning capability is proposed and fabricated. Compared with traditional HPM antennas, the DEMRA does not need to be sealed and can work directly in open-air conditions. The DEMRA can realize free regulation of the radiation beam within a cone angle of 90° and has a power handling capacity of 1 GW/m2. As verification, a protype working at 10 GHz is fabricated and low-power experiments are carried out. Experimental results are consistent with the simulation, proving that the DEMRA has a bandwidth exceeding 600 MHz. During the scanning process, the aperture efficiency is always higher than 48.98%, and the side lobe level remains below −15 dB. At the same time, the cross-polarization component is less than −15 dB, while the main lobe-axis ratio remains within 4.5 dB, confirming its beam scanning capability.
Erminnie A. Smith (1836–1886)
Authors: Kilarski Marcin 
Published: June 2022

SummaryIn this paper I discuss the varied contributions of Erminnie Adele Smith (1836–1886), a linguist, ethnologist, and geologist, who has a significant but underestimated place in the history of the study of North American languages. Among others, Smith was among the first scholars to collaborate extensively with Indigenous consultants and the first woman in the history of Western linguistics who published works on grammatical gender. Such achievements point to the need to reconsider her life and work in the context of the reception of the first generation of women in American anthropology as well as the study of gender in Iroquoian languages since the mid-19th century.
Source language difficulties in learner translation

AbstractThis study uses an error-annotated, mass-media subset of a sentence-aligned, multi-parallel learner translator corpus to reveal source-language items that are challenging in English–Russian translation. Our data includes multiple translations of the most challenging source sentences, drawn from a large collection of student translations on the basis of error statistics. This sample was subjected to manual contrastive-comparative analysis, which resulted in a list of English items that were difficult for students. The outcome of the analysis was compared to the topics discussed in translation textbooks that are recommended for BA and specialist-degree students in Russia. We discuss items that deserve more prominence in training as well as items that call for improvements to traditional learning activities. This study presents evidence that a more empirically motivated design of the practical translation syllabus as part of translator education is required.
The reception of Wüster’s General Theory of Terminology
Authors: Humbley John 
Published: June 2022

Abstract
Eugen Wüster is generally credited with founding modern Terminology theory. Over time, his legacy has been evaluated from various points of view, each new approach positioning itself against what came to be known as the General Theory of Terminology. Reappraisal came in particular from Socioterminology, Sociocognitive, Communicative and Textual Terminology and from Translation Studies. While some approaches set out to build on Wüster’s principles, most sought to distance themselves from them. It is argued that his contribution can only be properly assessed by placing his activities in their historical context and by recognizing that theory was only one part of Wüster’s achievement: he is at least as important for having embedded terminology in areas such as standardization and specialized communication.
Multidimensionality
Authors: Bowker Lynne 
Published: June 2022

Abstract
Multidimensionality is a phenomenon of conceptual classification that arises when concepts are classified in more than one way within a concept system according to different characteristics. Because multidimensionality can be complex and cause information overload, early terminologists focused on the most common dimension. In the 1990s, knowledge-based approaches emerged, partly inspired by cognitive science models. Technological advances offered the possibility of managing multiple inheritance and generating graphical representations, making it easier to work with multidimensionality. Corpus-based techniques that used lexical knowledge patterns to uncover conceptual relations soon followed. Terminologists have thus incorporated multidimensionality into successive terminological knowledge bases, offering richer representations of multiple dimensions and a more holistic understanding of concepts. These resources also explore ways of addressing information overload.
Causes of terminological variation
Authors: Freixa Judit 
Published: June 2022

Abstract
The aim of studying terminological variation is to understand the reasons for the existence of several denominations for the same concept in specialised texts. Based on Freixa (2006), this article resumes the study of the causes of terminological variation and updates the proposal with a literature review of the research on this topic in recent years. We first situate terminological variation as a natural and necessary feature of terminological units. We then give an overview of the advances in studying and representing variation and its causes. This leads to the main part of the article, which reviews the different causes of variation and provides new nuances and examples in light of the literature reviewed.
Diachronic variation
Authors: Dury Pascaline 
Published: June 2022

Abstract
The use of the diachronic perspective to study specialised terms and concepts is a research area which has long been under-exploited in Terminology. Until very recently, studies on specialised terminologies were carried out only from a synchronic perspective, which is still predominant, although the use of the diachronic perspective is now less marginal. Specialised diachrony, i.e., the many changes occurring in terms and concepts over time should be considered as an integral part of term variation. Moreover, it gives access to terminological knowledge which is not often described when studied in synchrony, and it also provides knowledge about the conceptual structuring of specialised fields.
