An improved fault control strategy for virtual synchronous generator with the coordination of STATCOM during unbalanced fault
Authors: Wang Yu , Ji Liang , Ding Yifan , Chang Xiao , Hong Qiteng , Li Botong , Li Zhenkun , Yang Xingwu 
Published: June 2023

AbstractThe virtual synchronous generator (VSG) is a good solution for stabilizing the power system with high penetration of renewable energy. However, in case of serious unbalanced voltage disturbance/fault, the conventional VSG may lose voltage, inertia, and damping support characteristics to the grid and even can cause disconnection of renewable energy. This paper proposes an improved fault control strategy for VSG with the coordination of STATCOM. The proposed method can provide sufficient voltage support while keeping continuous system inertia and damping support under severe unbalanced fault. In the paper, an improved VSG and STATCOM control topology based on positive and negative sequence current control are first proposed so as to keep the damping and inertia support to grid during the grid fault. Secondly, the voltage support control method for the VSG with improved topology during unbalanced fault is introduced, which can achieve multiple control objectives, in terms of voltage support, current limitation, and active power output simultaneously. Then a coordination control scheme of improved VSG and STATCOM is developed so as to optimize the maximum control objectives in all possible scenarios, especially in the case of severe unbalanced fault. Finally, the effectiveness of the method is verified by using the MATLAB/SIMULINK simulation platform.
Discourses on gender in climate change adaptation projects of Bangladesh
Authors: Dev Debashish Sarker , van de Fliert Elske 
Published: June 2023

Abstract
The study examines why certain discourses on gender are more powerful than others in describing intentions for
gender inclusion in development projects. A critical discourse analysis was carried out on texts of climate change adaptation
projects implemented during 2009–2020 in rural Bangladesh. This article argues that gender is currently not considered enough in
climate action and that gender discourses focus primarily on ‘women’s participation, more precisely, ‘women’s presence in poverty
reduction and empowerment projects. The discourses reinscribe to the long-established economic priorities of development rather
than exploring new dimensions to challenge social norms that define perpetual gender inequalities. This study suggests that
greater attention is required to address the gender realities of non-binary categories, ethnic groups, non-poor social classes,
and religious minorities to effectively plan and implement adaptation projects to support the diverse needs of vulnerable
people.
Effect of reaction path on high-pressure synthesis and stability of ruthenium hydrides
Authors: Li Xin , Huang Xiaoli , Cui Tian 
Published: June 2023

Abstract
This study explores the behavior of ruthenium hydrides under high-pressure conditions through three thermodynamical paths using laser-heated diamond anvil cells. The synthesis of RuH0.9 occurs gradually exceeding the pressure of 23.5 GPa in the ambient temperature path, while RuH is successfully synthesized at pressures above 20 GPa and a temperature of 1500 K. High-temperature conditions are found to reduce the pressure required for synthesis. The results demonstrate that the hydrogen occupancy of octahedral interstitial sites in the ruthenium hydrides is found to reach saturation with complete hydrogen absorption in the high-temperature path. Moreover, the crystallinity of the ruthenium hydride samples improves at higher temperatures, with the grain size increasing from 10 nm in the ambient temperature path to submicron in the high-temperature path. However, the predicted RuH6 and RuH3 were not observed in the present work.
Effect of the Rashba interaction on the tunneling time and Hartman effect in an 8-Pmmn borophene superlattice
Authors: Sattari Farhad 
Published: June 2023

Abstract
The spin-dependent group delay time and Hartman effect as well as the valley/spin polarization in an 8-Pmmn borophene superlattice under Rashba interaction are investigated theoretically, by using the stationary phase and the transfer matrix approaches. The group delay time depends on the spin degree of freedoms, and can be effectively controlled by changing the direction of superlattice, incident electron angle and Rashba strength. Both the valley and spin polarization reveal a strong dependence on the number of the superlattice barriers. Furthermore, group delay time oscillates as the width of the potential barriers increases, but in special conditions, the dependence on the width of the potential barriers will disappear. Interestingly, by increasing the angle of the direction of the superlattice the Hartman effect can be observed for most electron incidence angles. Our study show that, the 8-Pmmn borophene superlattice can be useful for future electronics and spintronics applications.
Improved performance in temperature and speed of TCP artificial muscles for soft wearables robots by length modification
Authors: Gonzalez-Vazquez Alberto , García Lorenzo , Kilby Jeff 
Published: June 2023

Abstract
Artificial muscles provide a unique solution for wearable rehabilitation robots (WRRs) because they are compliant, compact, and lightweight. Twisted and coiled polymer actuators (TCPs) are artificial muscles from thermally activated polymer fibres. They present high power density, linearity, stress and strain compared to other artificial muscles. Nevertheless, as TCPs require heat to start, their main barrier for widespread use in WRRs are their slow reaction times and the high temperatures they reach. Previous studies have analysed different parameters, like fibre material, fibre diameter, and various cooling systems, to improve TCP frequency response and working temperature. Nevertheless, the length of the actuator has not been explored as a possible parameter to enhance the actuation performance in this regard. This work focuses on studying the behaviour of TCPs with different lengths and how the performance in frequency response and temperature can be improved using the length as a primary parameter, as they are critical for wearable robots. First, a characterisation of the TCPs was performed. Then, a method to improve frequency response, based on offsets on long actuators was implemented and validated using a chirp signal. The experimental results show that the mechanical characteristics are similar regardless of the actuator’s length. They reached a strain of 10% with a power of 0.16 W cm−1. However, the electrothermal properties changed as the power needed to increase temperature was higher when the actuator was enlarged. Therefore, an improvement in the required temperature was found, able to reduce the temperature with the same frequency response. Regarding the technique to enhance the speed of the actuator, it was possible to increase the frequency by 0.0006 Hz for each mm applied as an offset. Hence, the frequency response for the same displacement was increased linearly as the actuator was elongated.
Managed retreat: a nationwide study of the local, racially segmented resettlement of homeowners from rising flood risks
Authors: Elliott James R , Wang Zheye 
Published: June 2023

Abstract
The government-funded retreat of homeowners from flood-prone housing is a globally ascendant policy of climate adaptation. Yet, we still know relatively little about some fairly basic questions involving its participants: e.g. How much risk do homeowners tolerate before retreating? Where do they move? Does that move reduce their future flood risk? And, to what extent do answers to these questions vary by the type of racial and ethnic communities in which they live? To answer these questions, we combine novel address-to-address residential history data with future flood risk estimates and indices of local context to better understand how retreat is unfolding across the United States. Results indicate that, when voluntarily undertaken, retreat is a highly local process that yields notable reductions in household flood risk. These movements, however, are racially segmented, with homeowners in majority-White communities being more likely to stay in the face of higher risk and less likely to relocate to nearby areas that are not also majority-White.

Abstract
We study signatures of physical constraints on free rotations of rigid bodies. We show analytically that the physical or non-physical nature of the moments of inertia of a system can be detected by qualitative changes both in the Montgomery phase and in the tennis racket effect.
Non-uniqueness in plane fluid flows
Authors: Gimperlein Heiko , Grinfeld Michael , Knops Robin , Slemrod Marshall 
Published: June 2023

Examples of dynamical systems proposed by Z. Artstein and C. M. Dafermos admit non-unique solutions that track a one parameter family of closed circular orbits contiguous at a single point. Switching between orbits at this single point produces an infinite number of solutions with the same initial data. Dafermos appeals to a maximal entropy rate criterion to recover uniqueness.

These results are here interpreted as non-unique Lagrange trajectories on a particular spatial region. The corresponding special velocity is proved consistent with plane steady compressible fluid flows that for specified pressure and mass density satisfy not only the Euler equations but also the Navier-Stokes equations for specially chosen volume and (positive) shear viscosities. The maximal entropy rate criterion recovers uniqueness.
PharmBERT: a domain-specific BERT model for drug labels
Authors: ValizadehAslani Taha , Shi Yiwen , Ren Ping , Wang Jing , Zhang Yi , Hu Meng , Zhao Liang , Liang Hualou 
Published: June 2023

Abstract
Human prescription drug labeling contains a summary of the essential scientific information needed for the safe and effective use of the drug and includes the Prescribing Information, FDA-approved patient labeling (Medication Guides, Patient Package Inserts and/or Instructions for Use), and/or carton and container labeling. Drug labeling contains critical information about drug products, such as pharmacokinetics and adverse events. Automatic information extraction from drug labels may facilitate finding the adverse reaction of the drugs or finding the interaction of one drug with another drug. Natural language processing (NLP) techniques, especially recently developed Bidirectional Encoder Representations from Transformers (BERT), have exhibited exceptional merits in text-based information extraction. A common paradigm in training BERT is to pretrain the model on large unlabeled generic language corpora, so that the model learns the distribution of the words in the language, and then fine-tune on a downstream task. In this paper, first, we show the uniqueness of language used in drug labels, which therefore cannot be optimally handled by other BERT models. Then, we present the developed PharmBERT, which is a BERT model specifically pretrained on the drug labels (publicly available at Hugging Face). We demonstrate that our model outperforms the vanilla BERT, ClinicalBERT and BioBERT in multiple NLP tasks in the drug label domain. Moreover, how the domain-specific pretraining has contributed to the superior performance of PharmBERT is demonstrated by analyzing different layers of PharmBERT, and more insight into how it understands different linguistic aspects of the data is gained.
Different levels of visuospatial abilities linked to differential brain correlates underlying visual mental segmentation processes in autism

Published: June 2023

Abstract
The neural underpinnings of enhanced locally oriented visual processing that are specific to autistics with a Wechsler’s Block Design (BD) peak are largely unknown. Here, we investigated the brain correlates underlying visual segmentation associated with the well-established autistic superior visuospatial abilities in distinct subgroups using functional magnetic resonance imaging. This study included 31 male autistic adults (15 with (AUTp) and 16 without (AUTnp) a BD peak) and 28 male adults with typical development (TYP). Participants completed a computerized adapted BD task with models having low and high perceptual cohesiveness (PC). Despite similar behavioral performances, AUTp and AUTnp showed generally higher occipital activation compared with TYP participants. Compared with both AUTnp and TYP participants, the AUTp group showed enhanced task-related functional connectivity within posterior visuoperceptual regions and decreased functional connectivity between frontal and occipital-temporal regions. A diminished modulation in frontal and parietal regions in response to increased PC was also found in AUTp participants, suggesting heavier reliance on low-level processing of global figures. This study demonstrates that enhanced visual functioning is specific to a cognitive phenotypic subgroup of autistics with superior visuospatial abilities and reinforces the need to address autistic heterogeneity by good cognitive characterization of samples in future studies.
Beyond Expectations of Resilience: Towards a Language of Care
Authors: Shwaikh Malaka 
Published: June 2023

AbstractThis article draws from hundreds of interviews and conversations with survivors of wars and violence in different contexts to show the limits of resilience. I bring together stories from my experiences talking with survivors across many countries—including Palestine, South Africa, Northern Ireland, Qatar, Jordan, and the United Kingdom. Through employing ethnographic and autoethnographic methods, I argue that resilience expectations may impose supernatural coping mechanisms on communities struggling with adversities, romanticize them as exemplary in enduring injustices, obscure their humanity, and normalize (structural) violence they continue to experience or reduce its severity. I question who benefits from an overemphasis on and financing of resilience, especially within (international) development organizations. The communities I spoke with all contend that resilience is not just a useless word but also a discourse, a way of thinking, and a policy implemented during difficulties. They emphasize that the cheap (re)production of them as extraordinary people, who are expected to endure suffering, is violent because it places the onus on them to be resilient on issues beyond their control while, often, ignoring layers of (structural) violence and subsequent traumas they face. As an alternative discourse to resilience, I propose a collective and caring approach that deals with root causes of violence instead of ignoring them.
Time and space as two basic attributes of Buddhist monuments: An introduction to the design, implementation, and application of the data platform of Buddhist monuments in China
Authors: Wang Weiqiao , Li Kequan 
Published: June 2023

Abstract
The Data Platform of Buddhist Monuments in Time and Space (buddhist.wiki) is a research infrastructure that focuses on collecting and presenting related materials of Buddhist monuments, which are presented by Geo map and complete archive from five aspects: overview, architecture, history, art, and personage. Time and space are extracted as two basic attributes and applied as design dimensions to organize the order of huge amounts of graphic and text data, which provide systematic convenience for the collection, presentation, search, and research for the data platform. After a preliminary introduction to the importance of Buddhist monuments, data characteristics, and construction purposes of the data platform, this article introduces its design, implementation, and application from three aspects: first, the graphic and text data source characteristics related to Buddhist monuments are investigated to analyse how time and space (data attributes) are used as design dimensions to achieve high-degree data collection and presentation integration; secondly, data platform implementation is introduced in detail, including data acquisition, data storage design, and system design; finally, Tiantong Si is taken as an example to specifically introduce how time and space affect data platform design methods and participate in specific applications.
Prehabilitation in Patients With Breast Cancer Receiving Neoadjuvant Therapy to Minimize Musculoskeletal Postoperative Complications and Enhance Recovery (PREOPtimize): A Protocol for a Randomized Controlled Trial
Authors: Casanovas-Álvarez Anabel , Sebio-Garcia Raquel , Ciendones Magda , Cuartero Jordi , Estanyol Blanca , Padrós Josep , García-Valdecasas Bárbara , Barnadas Agustí , Masia Jaume 
Published: June 2023

Abstract

Objective
The aim of this study is to assess the effects of a prehabilitation program (PREOPtimize), consisting of Nordic Walking and resistance training exercises plus health education among patients with breast cancer, who are receiving neoadjuvant therapy to enhance postoperative functionality of the affected arm. A secondary aim will be to compare the short-term effects of the intervention on other patient-reported outcome measures.

Methods
This will be an assessor-blind, randomized controlled trial with a parallel group design conducted at a tertiary hospital. A sample of 64 patients with breast cancer scheduled for surgery and undergoing neoadjuvant chemotherapy will be recruited for the trial and randomly allocated to either (1) a prehabilitation program consisting of 2 weekly sessions of 75 minutes of Nordic Walking, muscle strengthening exercises, and health education sessions conducted between the fourth month of treatment and surgery or (2) usual care. Patients in both groups will be assessed at baseline, before surgery, and at 1 and 3 months after surgery. Assessed outcomes include functionality of the affected arm (QuickDash), arm volume, range of motion, handgrip strength, pain, fatigue, functional capacity, physical activity levels, and health-related quality of life. Adherence to the intervention in the prehabilitation group and adverse events will also be recorded.

Impact
Prehabilitation for patients affected by breast cancer is rarely implemented in clinical practice. The results obtained with the PREOPtimize trial could show that prehabilitation is a feasible intervention for patients with breast cancer receiving neoadjuvant therapy that might enhance postoperative recovery of upper arm function as well as improve overall physical performance and health-related quality of life.

Abstract
A total of seven Japanese laboratories participated in an intercomparison study to estimate the dose given to tooth enamel samples, using the electron spin resonance method. Each of four of the participating laboratories prepared a set of tooth enamel samples, using the electron spin resonance method. Four of the participating laboratories each prepared a set of tooth enamel samples, consisting of seven standard aliquots irradiated from 100 to 2000 mGy and three samples with an ‘unknown’ dose between 140 and 960 mGy, were intended to eliminate bias from sample preparation. Although not all seven laboratories measured all four sets of samples, the major finding was that systematic biases in estimating doses may be caused by differences in laboratory measurements rather than by the enamel extracting procedures. When doses were averaged by measurements made by multiple laboratories, the averaged values were close to the actual values. Scattering in the intercepts in the standard dose response would be a serious problem in actual dosimetry where no background sample is available.

Abstract
Current pathways of care for whiplash follow a “stepped care model,” result in modest treatment outcomes and fail to offer efficient management solutions. This study aimed to evaluate the effectiveness of a risk-stratified clinical pathway of care (CPC) compared with usual care (UC) in people with acute whiplash. We conducted a multicentre, 2-arm, parallel, randomised, controlled trial in primary care in Australia. Participants with acute whiplash (n = 216) were stratified for risk of a poor outcome (low vs medium/high risk) and randomised using concealed allocation to either the CPC or UC. In the CPC group, low-risk participants received guideline-based advice and exercise supported by an online resource, and medium-risk/high-risk participants were referred to a whiplash specialist who assessed modifiable risk factors and then determined further care. The UC group received care from their primary healthcare provider who had no knowledge of risk status. Primary outcomes were neck disability index (NDI) and Global Rating of Change (GRC) at 3 months. Analysis blinded to group used intention-to-treat and linear mixed models. There was no difference between the groups for the NDI (mean difference [MD] [95% confidence interval (CI)] −2.34 [−7.44 to 2.76]) or GRC (MD 95% CI 0.08 [−0.55 to 0.70]) at 3 months. Baseline risk category did not modify the effect of treatment. No adverse events were reported. Risk-stratified care for acute whiplash did not improve patient outcomes, and implementation of this CPC in its current form is not recommended.
