Published: February 2024

AbstractThe new power system is characterized by high penetration of renewable energy sources and a high proportion of power electronics (namely, double‐high). The grid‐forming control is an effective method to improve the grid‐connected stability of wind turbine generators (WTGs) in the “double‐high” grid. The control method based on the DC‐link voltage can effectively realize the grid‐forming control for WTGs. However, there is a disadvantage that the DC‐link voltage cannot be maintained at the given value. To address this, the grid synchronization mechanism of DC‐link voltage is explored and the specific implementation of a novel DC‐link voltage synchronous control applicable to full‐scale power conversion WTGs is proposed. Then, the boundary of the inertial coefficient is probed through the state‐space method. And a compensation control is proposed to enlarge the inertial response capability based on the mechanism of damping characteristics. Finally, the PSCAD/EMTDC simulation and RTLAB hardware‐in‐loop experiment show that the synchronization frequency can accurately map the grid frequency changes in real‐time under the premise that the DC‐link voltage remains constant. In addition, the inertial coefficient can be increased by more than five times with the compensation strategy, which can enhance the support capability of the WTGs to the power grid.

Introduction: Musculoskeletal (MSK) disease is a substantial global burden, especially in lower income countries. However, limited research has been published on MSK health by scholars from these countries. We aimed to study the distribution of authorships, including trends in peer-reviewed orthopaedic publications based on each author’s affiliated institution’s country income status. Methods: Based on a bibliometric search, 119 orthopaedic-related journals were identified using the Journal Citation Reports database. Details of all scientific articles published in these journals between 2012 and 2021 were used to study trends and association between each of the author’s affiliated institution’s country income status, using the World Bank Classification. Results: Of the 133,718 unique articles, 87.6% had at least one author affiliation from a high-income country (HIC), 7.0% from an upper-middle income country (UMIC), 5.2% from a lower-middle income country (LMIC), and 0.2% from a low-income country (LIC). Overall, these articles were cited 1,825,365 times, with 92.5% of citations from HIC-affiliated authors and < 0.1% from LIC-affiliated authors. Over the 10-year study period, HIC-affiliated articles demonstrated the largest increase in the number of publications (9107–14,619), compared to UMIC-affiliated (495–1214), LMIC-affiliated (406–874), and LIC-affiliated articles (4–28). Conclusions: There are large and persistent disparities in orthopaedic research publications based on the country income status of the author’s affiliated institution, especially in the higher impact orthopaedic journals. Efforts should be made to increase opportunities for scholars from LICs and LMICs to publish their research in high-impact orthopaedic journals.

Published: February 2024

SummaryÄtherische Öle aus Pflanzen enthalten antivirale Wirkstoffe, die unter anderem die Viren davon abhalten, in die Wirtszelle einzudringen und auf diese Weise eine Infektion sowie eine Vermehrung des Krankheitserregers verhindern. Daher kommen ätherische Öle bei einer Vielzahl von Viruserkrankungen zum Einsatz, unter anderem bei Herpes simplex, Herpes genitales, bei grippalen Infekten, Covid oder Influenza, aber auch prophylaktisch zur Vorbeugung von Infektionen. Wichtig ist, das geeignete Öl in der passenden Dosierung auszuwählen. Insbesondere bei Menschen mit chronischen Atemwegserkrankungen wie Asthma oder COPD, bei Epileptiker*innen, Schwangeren oder Kindern ist Vorsicht geboten.
Covid, Long Covid und Co. – eine osteopathische Herausforderung
Authors: Wagner Gudrun 
Published: February 2024

SummaryDie osteopathische Behandlung des Immunsystems, prophylaktisch wie regenerativ nach Infektion, ausgleichend nach Impfreaktionen oder unterstützend bei Long-Covid-Symptomatiken, ist wieder aktuell. Die Funktion des Immunsystems beginnt mit dem Erkennen des Selbst und Nicht-Selbst. Gute Funktion bedeutet zuerst das Erkennen von Selbst und danach das Abgrenzen oder Verteidigen. Die Vielfalt des Immunsystems führt zu verschiedenen praktischen Anwendungen: zuerst das Gesamtbild der Patient*in verstehen und die Strukturen behandeln, dann in den Extrazellulärraum tauchen und „mitreden“ und schließlich das Selbst und das Nicht-Selbst im Anderen verstehen und entdecken und so eine Erweiterung osteopathischer Tools erfahren.Der osteopathische Ansatz erfasst das Immunsystem der Patient*innen nicht nur in seiner gesamten Funktion, sondern ermöglicht auch die (Wieder-)Herstellung eines funktionalen Gleichgewichts. Die Auswirkungen sind enorm, ist doch die Entität der Patientin bzw. des Patienten in ihrem fluiden Ganz-Sein innerhalb der Grenzen des Selbst, in ihrer Lebendigkeit in der Lage, sich vollkommen neu zu orientieren. So kann im gesamten zellulären Kontinuum und darüber hinaus Gesundheit entfaltbar und eine (neue) Integrität stabilisiert werden.
Utilizing a Second Flap to Address the Effect of Postradiotherapy Soft Tissue Fibrosis in Head and Neck Malignancy
Authors: Biswas Gautam , Mathew Jovin George , Kaur Amrita , Panchal Karnav Bharat 
Published: February 2024

Abstract
Background Late effects of adjuvant radiation therapy (RT) on soft tissues can lead to hair loss, pigmentary changes, loss of tissue volume, and fibrosis, which appear months to years after the treatment. These changes are often progressive and are because of tissue hypoxia due to radiation-induced capillary endothelial damage. Tissue hypoxia may be compounded by subclinical infection following minor trauma, exposed hardware, or associated osteoradionecrosis. The combined effect of these factors causes significant deformities in soft tissue, affecting both function and appearance. Such changes are also seen in primarily transferred flaps, which have been radiated, resulting in severe, progressive soft tissue fibrosis, compromising function and aesthetics. In selected cases, a second flap may be needed to restore function and volume.
Methods Data of patients who underwent secondary soft tissue transfers for postradiotherapy-related soft tissue changes were collected from the hospital electronic medical records, from January 2019 to 2023. Details regarding the primary surgery, dose, duration of adjuvant RT, time interval between adjuvant RT and secondary soft tissue transfer, indications, and the choice of the second flap were analyzed.
Results Twenty-one patients had undergone secondary soft tissue transfer for extensive soft tissue fibrosis. In addition, associated compounding features like exposed implant and volume loss were observed. Two patients with osteoradionecrosis also had associated extensive soft tissue fibrosis necessitating replacement. Out of these 21 patients, 13 had undergone free tissue transfers, while 7 locoregional tissue transfers.
Conclusion Late sequelae of adjuvant RT changes usually present from 6 months onwards. The radiated hypoxic tissue, due to capillary damage, leads to a chronic progressive fibrotic stage, causing loss of soft tissue volume and fibrosis. Replacing this tissue with a vascularized flap helps to restore volume and correct these secondary changes, improving overall quality of life.
‘Dead faces laugh’: Medievalist hungers and Irish republican time, 1917-1981
Authors: Petrizzo Francesca 
Published: February 2024

AbstractThe article analyses the temporal entanglements of personal and historical time through hunger-striking protests in Ireland and their commemoration in medieval imagery, reflecting on the role of medievalism and temporality in nation-building by insurgent agents. Between 1917 and 1981, twenty-two Irish republican paramilitary prisoners undertook hunger strikes to the death for recognition of political status and protest against their prison regimes. While some of these deaths went unremarked by the wider public because of state censorship and lack of support, others catalysed worldwide attention, and succeeded in pitching a compelling national and political narrative for their supporters. The article focuses on how the use of medievalism in examining and commemorating these deaths highlights the vivid temporal collapse between the present of the individual and the past of the nation, and the way this can appeal to the protest’s audience, while making a powerful political bid for the legitimacy of the insurgents’ national narrative. The article examines temporal entanglement both as practiced by the audience of the hunger strikes, from poets such as W.B. Yeats and Seamus Heaney to journalists and scholars, and by the republican community itself, whether by hunger strike survivors, their comrades, or their families, bringing together literary, material, and art historical evidence to show its relevance and pervasiveness. By doing so, the article achieves a study of the ways medievalist temporalities interact with political and personal history, in a bid for the ownership and definition of the nation.
Bidirectional relationship between self-rated health and the big five personality traits among Chinese adolescents: a two-wave cross-lagged study
Authors: Cao Xiaojie , Ji Siduo 
Published: February 2024

AbstractPrevious literature has focused mainly on the correlation between self-rated health and the Big Five personality traits. However, less is known about the bidirectional relationship between self-rated health and the Big Five personality traits among adolescents, leading to an insufficient understanding of the directional nature of their relationship. Based on a longitudinal survey database, this study empirically examines the bidirectional relationship between self-rated health and the Big Five personality traits among 7967 adolescents in China. Using a two-wave cross-lagged model, the findings emphasize the role of self-rated health in predicting the Big Five personality traits. Specifically, self-rated health significantly positively predicts subsequent extraversion, agreeableness, openness, and conscientiousness, whereas self-rated health significantly negatively predicts subsequent neuroticism. In addition, neuroticism significantly negatively predicts self-rated health, and openness significantly positively predicts self-rated health. The present study provides substantial evidence for the relationship between self-rated health and the Big Five personality traits in the Chinese context and contributes to a deeper understanding of the interplay between these variables.
The impact of adjunct instruction on EFL academic writing at university
Authors: Roquet Pugès Helena , Navarro Gil Noelia , Nicolás-Conesa Florentina 
Published: February 2024

Abstract
Adjunct instruction (AI), a form of content-based instruction, can provide students with opportunities to learn disciplinary discourse in context. Few studies have explored the extent to which AI affects students’ written production over time. This study aims to analyze the impact of a 60-hour AI course in English on writing complexity, accuracy, fluency (CAF) and on holistic measures in two groups with different exposure to English. The participants were 51 first-year Dentistry students from two strands, English-Medium of Instruction (EMI) (n = 21) and first language (L1 Catalan/Spanish) (n = 30). After 60 hours of AI, the EMI+AI group improved lexical diversity, while the L1+AI group improved accuracy and some holistic measures. Correlations between CAF and holistic measures indicate defining features of second language writing in each strand. The benefits of adjunct instruction for writing development are discussed in the light of the two settings explored.

Published: February 2024

Abstract
During the development of new therapeutic devices, comprehensive experimental investigations are necessary in all phases of the process. This requires the provision of device prototypes with reproducible and comparable operating parameters. In the current study, such miniature neon plasma jet prototypes designated for medical applications have been manufactured, characterized, and compared. The multi-parametric characterization included measurements of energy, power, temperature, leakage current, effluent length, and relative as well as absolute radiation. The dissipated electrical power and the optical emission in the UV range were identified as parameters indicating definable tolerances to sort out a device with inadequate species output. A liquid phase model was used to investigate reactive species deposition into simple matrices. Based on these investigations, a quality control procedure for manufacturing new device series is proposed. In conclusion, our findings suggest a test concept of achieving reproducible and comparable plasma device characterization as a putative quality control measure for lab-scale plasma source production.
Magnetic tunability in tetragonal Mn–Rh–Ir–Sn inverse Heusler compounds
Authors: Mozur Eve M , Seshadri Ram 
Published: February 2024

Abstract
Gaining control over magnetic structure has been an ongoing challenge in materials that form complex, nanoscale, and non-collinear magnetic configurations. Recently, it was predicted that tuning the ratio of the Dzyaloshinskii–Moriya interaction to the uniaxial magnetic anisotropy in tetragonal inverse Heuslers through changes in composition could allow a range of interesting magnetic states to be accessed, from simple ferrimagnetism, to helical and antiskyrmionic phases. Here, we show tunability of the magnetic phase behavior in the Mn–Rh–Sn system through Ir substitution on the Rh substructure. Iridium substitution correlates to an increase in the strength of ferromagnetic exchange couplings, at the expense of antiferromagnetic exchange couplings. However, we do not observe the complex non-collinear magnetic phases proposed previously, likely due to the extremely narrow composition window where these phases are predicted to form in a bulk sample. This work highlights the sensitivity of complex magnetic structures to stoichiometry, which makes them difficult to discover empirically.
Dimensionality effects on trap-assisted recombination: the Sommerfeld parameter
Authors: Turiansky Mark E , Alkauskas Audrius , Van de Walle Chris G 
Published: February 2024

Abstract
In the context of condensed matter physics, the Sommerfeld parameter describes the enhancement or suppression of free-carrier charge density in the vicinity of a charged center. The Sommerfeld parameter is known for three-dimensional systems and is integral to the description of trap-assisted recombination in solids. Here we derive the Sommerfeld parameter in one and two dimensions and compare with the results in three dimensions. We provide an approximate analytical expression for the Sommerfeld parameter in two dimensions. Our results indicate that the effect of the Sommerfeld parameter is to suppress trap-assisted recombination in decreased dimensionality.

Our Ni K-edge x-ray Absorption Spectroscopy results show that there is a significant reduction in the first coordination number around Ni central atom on doping. Further, with doping, there is distortion in the first coordination shell around Ni. This suggests, with V doping, the local structure around Ni is different from the global structure as obtained from the x-ray Diffraction results. Interestingly, with doping, we observe a direct connection between the extent of distortion at RT and the magnetic disorder obtained at 2 K. We believe our results will motivate the scientific community to further study the interplay between the structural disorder and quantum fluctuations with temperature at the local level.
High-frequency visualization of flexible structures using an event-triggered camera: multiple flapping membranes
Authors: Lyu Zhen , Cai Weiwei , Liu Yingzheng 
Published: February 2024

Abstract
Optical measurements of fluid–structure interaction (FSI) usually require high-speed imaging techniques. Traditional high-speed cameras are expensive and cannot record data continuously for long periods. An inexpensive and high-frequency measurement method that utilizes an event-triggered camera and a strobe laser is proposed in this paper. In this method, the k-means clustering technique was first employed to determine the precise time window in which to reconstruct frames from event data. Then, a Kalman filtering algorithm was used to extract the dynamic deformation process of the flexible structures from the noisy event data. Wind tunnel flutter tests were conducted using various sets of parallel membranes to examine the proposed method. Under the illumination of a 30 mW strobe laser, membrane flapping was recorded at a resolution of 1280 × 720 pixels with a frame rate of 10 000 fps. With no camera memory storage limitations, the proposed method could continuously record the membrane flapping, thereby making it easy to capture the intermittent flutter phenomenon at the flutter boundary. Two flapping modes, i.e. symmetric mode and in-phase mode, were observed in the flutter of two membranes. Similar symmetric mode and out-of-phase mode were also observed in the flutter of three membranes. Membranes collisions and mode transitions were found in a certain wind speed range. For the first time, the collision processes between membranes were recorded during the flutter of multiple membranes. These collisions were found to be associated with the transitions between different flapping modes.
Transformer enhanced by local perception self-attention for dynamic soft sensor modeling of industrial processes

Published: February 2024

Abstract
The use of dynamic soft sensor modeling methods to mine the time-varying and dynamic characteristics of industrial process data is of great significance for improving production efficiency and quality, given the rapid development of industrial processes and the increasing prominence of dynamic changes in the production process. However, existing dynamic soft sensor methods have limited long-term memory capacity, making it difficult to capture the long dynamic dependence, which can severely affect the results of the soft sensor model. To address this issue, we propose a dynamic soft sensor model based on local perception transformer, where the transformer is applied to achieve global perception of the variables. Through the application of the self-attention mechanism in the transformer encoder, the dynamic tracking and prediction of parameters can be realized by assigning different weights to the process variables and quality variables at different time steps, thereby adapting to the time-varying nature of the process. Additionally, convolution is used to generate a Query and Key in the self-attention mechanism, thereby enhancing local information learning. The proposed dot product self-attention calculation method effectively utilizes local information, thereby reducing the potential impact of abnormal data at a certain moment. Furthermore, by utilizing LSTM to extract time series information, the final prediction result was obtained. In soft sensor modeling experiments of the sulfur recovery unit and debutanizer tower, our proposed model demonstrated higher prediction accuracy compared to other methods, such as SVR, MLP, LSTM, CNN + LSTM, and vanilla transformer.

Published: February 2024

Abstract
A new multi-mode electron and ion (MEI) imaging spectrometer with two arms of VMI and COLTRIMS/VMI (velocity map imaging/cold-target recoil-ion momentum spectroscopy) is designed to combine various photoelectron and ion detection modes for experiments at Shanghai soft x-ray free-electron laser (SXFEL) facility. The experiments can be optionally operated either with both ion and electron detection in a coincidence/covariance manner (VMI arm and COLTRIMS/VMI arm), or only photoelectron/photoion is detected with the high-resolution VMI arm. The simulated resolutions for 30–150 eV photoelectrons and 3.3 eV–18.0 eV N+ and N2+ photoions are up to 1.0% and 3.1%–1.0% according to our simulation, respectively. MEI spectrometer is expected to improve the experimental abilities significantly considering the low-repetition rate of the SXFEL and to enable the investigation of a diverse range of atomic and molecular phenomena triggered by soft x-ray free electron laser irradiation.
