AbstractMany complex magnetic structures in a high-symmetry lattice can arise from a superposition of well-defined magnetic wave vectors. These “multi-q” structures have garnered much attention because of interesting real-space spin textures such as skyrmions. However, the role multi-q structures play in the topology of electronic bands in momentum space has remained rather elusive. Here we show that the type-I anti-ferromagnetic 1q, 2q and 3q structures in an face-centered cubic sublattice with band inversion, such as NdBi, can induce unconventional surface state pairs inside the band-folding hybridization bulk gap. Our density functional theory calculations match well with the recent experimental observation of unconventional surface states with hole Fermi arc-like features and electron pockets below the Neel temperature. We further show that these multi-q structures have Dirac and Weyl nodes. Our work reveals the special role that band-folding from anti-ferromagnetism and multi-q structures can play in developing new types of surface states.

The Association Between Atypical Speech Development and Adolescent Self-Harm
Authors: McAllister Jan , Skinner Jane , Hayhow Rosemarie , Heron Jon , Wren Yvonne 
Published: April 2023

Background:
Adolescent self-harm is a major public health issue internationally. Various factors associated with adolescent self-harm have been identified, including being bullied and experiencing mental health problems. Stuttering and speech sound disorder are associated with both of these factors. It was hypothesized that both stuttering and speech sound disorder would be associated with self-harm. This is the first study to explore the relationship between communication disorders and adolescent self-harm.

Method:
Secondary analysis of a large, longitudinal, prospective, community sample, the Avon Longitudinal Study of Parents and Children, was carried out. Clinicians identified children who stuttered or exhibited speech sound disorder at the age of 8 years. When the cohort members were 16 years old, they were asked to complete a questionnaire about self-harm. Multinomial logistic regression was used to examine the associations between stuttering and speech sound disorder and the self-harm outcomes, adjusting for other relevant factors.

Results:
Of 3,824 participants with data for both speech status and self-harm, 94 (2.5%; 95% confidence interval [CI; 2.0, 3.0]) stuttered at 8 years of age and 127 (3.3%; 95% CI [2.8, 3.9]) displayed speech sound disorder. Speech sound disorder at the age of 8 years was associated with self-harm with suicidal intent in both unadjusted and adjusted models. Differences between the adjusted and unadjusted models were small, suggesting that speech sound disorder is largely an independent risk factor for self-harm with suicidal intent. Stuttering at the age of 8 years was not associated with adolescent self-harm, and there was no association between speech sound disorder and self-harm without suicidal intent.

Conclusion:
Compared with individuals without speech sound disorder, adolescents with speech sound disorder at the age of 8 years have twice the risk of reporting self-harm with suicidal intent, even when other important predictors are taken into account.

MMSCM: A multiple mobile sinks coverage maximization based hierarchical routing protocol for mobile wireless sensor networks
Authors: Liu Chun , Guo Liping 
Published: April 2023

AbstractMobile wireless sensor network (MWSN) adapts to the requirements of mobility of civil and military network devices and has received a lot of attention. Designing an efficient, low‐energy, and fault‐tolerant routing protocol for the frequently changing topology of highly mobile MWSNs is challenging. Most routing protocols today only support the movement of sensor nodes or only sink. This paper proposes a Multiple Mobile Sinks Coverage Maximization based hierarchical routing protocol for mobile wireless sensor networks (MMSCM), which allows sensor nodes and sinks to move simultaneously. The MMSCM divides the monitoring area into virtual grids and deploys a movable sink in each grid cell. Sink selects the appropriate next hop for each cluster head in the area to build an optimal routing forest and collects data from all routing tree root nodes at a uniform speed along the specified path with maximum coverage. Simulation results show that, compared with current advanced routing algorithms, the MMSCM protocol can better solve the network delay problem and improve data throughput while extending the network life cycle, which is more suitable for time‐sensitive application scenarios.
Variational mode decomposition enabled temporal convolutional network model for state of charge estimation
Authors: Zhang Zhaocheng , Cai Tao , Yuan Aote 
Published: April 2023

AbstractDue to the fast growth of electric vehicles (EVs) , estimation for Battery's State‐of‐charge (SOC) received significant research interests. The reason is that an accurate SOC estimation can significantly contribute to the reliability of EVs. A Variational Mode Decomposition (VMD) technique enabled Temporal Convolutional Network (TCN) model is proposed by the authors for SOC estimation. The proposed method first adopts time‐frequency analysis techniques to decompose voltage values into different frequency domains, each of which is analysed with the VMD technique to obtain its features as the input for the TCN model. Then, the proposed method combines outputs of different frequency domains with an attention module as the final output of the TCN model. Experiments on real battery datasets indicate that the proposed method outperforms the existing methods by 7.2% in mean absolute error and 6.13% in root mean square error. In addition, the error between the estimated and actual values using the proposed method is bounded by 2%.
Stability analysis of DFIG controlled by hybrid synchronization mode and its improved control strategy under weak grid
Authors: Xie Zhen , Li Mengjie , Yang Shuying , Zhang Xing 
Published: April 2023

AbstractIn order to improve the stability of doubly‐fed induction generator (DFIG)‐based wind turbines under weak grid, previous works have proposed the power synchronization control strategy in the rotor side converter (RSC). However, the potential instability risk of dc‐link voltage control in the grid side converter (GSC) has been neglected. Here, DFIG with power synchronization and phase‐locked synchronization for RSC and GSC respectively, is called as hybrid synchronization mode (HSM)‐controlled DFIG and, the full‐order state space model of HSM‐controlled DFIG are established. Eigenvalue and participation factor analysis shows that the HSM‐controlled DFIG is unstable under extremely weak grid due to the interaction of phase‐locked loop (PLL) and current‐loop in GSC. Furthermore, dominant pole analysis indicates that the HSM‐controlled DFIG exhibits weak damping at the AC side in strong grid. To enhance the stability of HSM‐controlled DFIG under extremely weak grid, an improved hybrid synchronization control strategy is proposed. The improved control strategy utilizes active power and dc‐link voltage to achieve PLL‐free operation of DFIG. The effects of the parameters in dc‐link voltage synchronous loop on control bandwidth, system stability and dynamic coupling are analysed. Finally, the validity of the theoretical analysis is investigated with experiments based on 2MW control‐hardware‐in‐loop platform.

AbstractGastrointestinal endoscopy is largely dependent on medical devices. The European Union (EU) has recently introduced stricter rules and regulations for the approval of medical devices. This has consequences both for endoscopists and for patients. The new regulations increase the need for clinical trials and observational studies for new and current devices used in endoscopy to ensure clinical benefit and reduce patient harm. European endoscopy environments should facilitate industry-sponsored clinical trials and registry studies to meet the demand for robust data on endoscopic devices as required in the new legislation. The European Society of Gastrointestinal Endoscopy (ESGE) will play an active role in the establishment of the new system.The EU is establishing independent expert panels for device regulation in gastroenterology and hepatology, including endoscopy, that are charged with assessing the requirements for device testing. The ESGE encourages endoscopists with expertise in the technical and clinical performance of endoscopy devices to apply for expert panel membership. The ESGE has provided information for interested endoscopists on the ESGE website. Private European companies called “notified bodies” are entitled to conduct device approval for the EU. The ESGE will actively engage with these notified bodies for topics related to the new endoscopy device approval process to ensure continued access to high quality endoscopy devices for endoscopists in Europe.

Background Measurement of colorectal polyp size during endoscopy is mainly performed visually. In this work, we propose a novel polyp size measurement system (Poseidon) based on artificial intelligence (AI) using the auxiliary waterjet as a measurement reference.
Methods Visual estimation, biopsy forceps-based estimation, and Poseidon were compared using a computed tomography colonography-based silicone model with 28 polyps of defined sizes. Four experienced gastroenterologists estimated polyp sizes visually and with biopsy forceps. Furthermore, the gastroenterologists recorded images of each polyp with the waterjet in proximity for the application of Poseidon. Additionally, Poseidon's measurements of 29 colorectal polyps during routine clinical practice were compared with visual estimates.
Results In the silicone model, visual estimation had the largest median percentage error of 25.1 % (95 %CI 19.1 %–30.4 %), followed by biopsy forceps-based estimation: median 20.0 % (95 %CI 14.4 %–25.6 %). Poseidon gave a significantly lower median percentage error of 7.4 % (95 %CI 5.0 %–9.4 %) compared with other methods. During routine colonoscopies, Poseidon presented a significantly lower median percentage error (7.7 %, 95 %CI 6.1 %–9.3 %) than visual estimation (22.1 %, 95 %CI 15.1 %–26.9 %).
Conclusion In this work, we present a novel AI-based method for measuring colorectal polyp size with significantly higher accuracy than other common sizing methods.

Published: April 2023

Abstract
Introduction Colonoscopy enables detailed endoscopic evaluation of the interior of the colon. Changes observed via colonoscopy may be subtle or pronounced and can sometimes mimic those of other diseases, such as deep intestinal endometriosis. The diagnosis of endometriosis in the distal sigmoid and rectum by colonoscopy has been described in previous case reports.
Objective We aimed to correlate the endoscopic changes found in the distal sigmoid and rectum with the presence of endometrial deposits confirmed by transrectal ultrasound (TRUS).
Methods We included 50 female patients referred to the endoscopy department at our institution for colonoscopy, rectosigmoidoscopy, or TRUS, who exhibited one or more symptoms associated with endometriosis.
Results The colonoscopic findings were normal in 36 patients but showed alterations in 14 patients. Among the latter, TRUS revealed involvement of the sigmoid and/or rectal wall in 11 patients.
Conclusions The endoscopic changes in the distal sigmoid or rectum described in this study were strongly associated with endometrial deposits confirmed using TRUS.

AbstractObjective Pelvic floor dysfunction can manifest as a spectrum including anorectal dysfunction, vaginal prolapse, and urinary incontinence. Sacrospinous fixation is a procedure performed by gynecologists to treat vaginal prolapse. The present study aims to evaluate the impact of transvaginal prolapse surgery on anorectal function.Materials and Methods We conducted a retrospective review of patients undergoing sacrospinous fixation surgery for vaginal prolapse between 2014 to 2020. Those with anorectal dysfunction who had also been evaluated by the colorectal service preoperatively and postoperatively were included for analysis. These patients were assessed with symptom-specific validated questionnaires. The effect of surgery on constipation and fecal incontinence symptoms was analyzed.Results A total of 22 patients were included for analysis. All patients underwent transvaginal sacrospinous fixation, and 95.4% also had posterior colporrhaphy for vaginal prolapse. There were a statistically significant improvements in the Fecal Incontinence Severity Index (FISI), the St. Mark's Incontinence Score (Vaizey), the embarrassment and lifestyle components of the Fecal Incontinence Quality of Life Score, the Constipation Scoring System, the Obstructed Defecation Score, and components of the Patient Assessment of Constipation Quality of Life score.Conclusion Transvaginal prolapse surgery leads to a favorable effect on anorectal function, with improvements in both obstructed defecation and fecal incontinence scores in this small series.

Published: April 2023

Abstract
Objectives To assess the status of the pelvic floor muscle (PFM) of premature ovarian insufficiency women (POI women) and the incidence of fecal incontinence (FI) and pelvic organ prolapse (POP).
Methods A secondary analysis of a cross-sectional study with 150 women with POI was performed. Pelvic floor muscle assessment was performed with the PERFECT scale. The subscales POPDI-6 and CRADI-8 of the questionnaire Pelvic Floor Distress Inventory-20 (PFDI-20) were used for pelvic floor symptoms focused on FI and POP. Moreover, FI and POP were also assessed as dichotomous variables (yes/no).
Results Women with FI and POP did not present differences in the PFM assessment across P (p = 0.61), E (p = 0.78), R (p = 0.22), and F (p = 0.79) variables when compared with women with POI; no differences were also seen between women with and without POP according the pelvic muscles: P (p = 0.91), E (p = 0.99), R (p = 0.62), and F (p = 0.10). Women with FI and POP presented higher scores in all PFDI-20 subscales and total score when compared with the control group (p < 0.05).
Conclusions Pelvic floor muscle assessment within POI women with or without FI or POP did not differ. However, PF symptoms are more severe in the FI or POP groups.
Knotless Arthroscopic Dorsal Scapholunate Capsulodesis: A Simplified Technique
Authors: Kakar Sanjeev , Kalapos Robert 
Published: April 2023

Abstract
Background Partial dorsal tears of the scapholunate ligament are a common soft-tissue injury in the wrist. These injuries have been a challenging problem and have gone through evolutionary changes over time from different open to arthroscopic techniques.
Objectives This study describes a knotless arthroscopic dorsal scapholunate (SL) capsulodesis technique using both the radiocarpal and midcarpal joint portals, indicated for acute or chronic reducible scapholunate instability.
Methods Using arthroscopy, we pierce the dorsal capsule on both sides of the dorsal torn remains of the SL ligament with two 18-gauge needles, one loaded with a 2–0 suture and the other with a nitinol wire loop. The 2–0 suture is weaved through the nitinol loop to create a knotless mattress stitch within the midcarpal joint and reduce the torn SL ligament.
Results In this article, we present the outcomes of a patient treated with this arthroscopic inside knotless technique in treating scapholunate instability.
Conclusions This knotless arthroscopic scapholunate capsulodesis technique provides a simple method to performing an arthroscopic dorsal capsulodesis.
The influence of ball in/out of play and possession in elite soccer: Towards a more valid measure of physical intensity during competitive match‐play

ABSTRACTThe physical demands of soccer match‐play have typically been assessed using a low‐resolution whole match approach ignoring whether the ball is in or out of play (BIP/BOP) and during these periods which team has possession. This study investigated the effect of fundamental match structure variables (BIP/BOP, in/out of possession) on the physical demands, and especially intensity, of elite match‐play. For 1083 matches from a major European league, whole match duration, and player physical tracking data, were divided into BIP/BOP, and in/out of possession periods throughout the match, using on‐ball event data. These distinct phases were used to derive absolute (m) and rate (m·min−1) of distance covered in total and within six speed categories during BIP/BOP and in/out possession. The rate of distance covered, an index of physical intensity, was >2‐fold greater during BIP vs BOP. Whole match total distance covered was confounded by BIP time and poorly associated with physical intensity during BIP (r = 0.36). Whole match rates of distance covered substantially underestimated those during BIP, particularly for higher running speeds (∼−62%). Ball possession markedly effected physical intensity, with the rates of distance covered running (+31%), at high‐speed (+30%) and in total (+7%) greater out than in possession. Whole match physical metrics underestimated the physical intensity during BIP, and thus the rate(s) of distance covered during BIP are recommended for accurate measurement of physical intensity in elite soccer. The greater demands of being out of possession support a possession‐based tactical approach to minimise fatigue and its negative consequences.
Emergent gravity from the IIB matrix model and cancellation of a cosmological constant
Authors: Klinkhamer F R 
Published: April 2023

Abstract
We review a cosmological model where the metric determinant plays a dynamical role and present new numerical results on the cancellation of the vacuum energy density including the contribution of a cosmological constant. The action of this model is only invariant under restricted coordinate transformations with unit Jacobian (the same restriction appears in the well-known unimodular-gravity approach to the cosmological constant problem). As to the possible origin of the nonstandard terms in the matter action of the model, we show that these terms can, in principle, arise from the emergent gravity in the IIB matrix model, a nonperturbative formulation of superstring theory.
Herglotz action for homogeneous cosmologies
Authors: Sloan David 
Published: April 2023

Abstract
We present an action from which the dynamics of homogeneous cosmologies can be derived. The action has no dependence on scale within the system and hence is more parsimonious in its description than the Einstein–Hilbert action. The form of the action follows that pioneered by Herglotz and hence allows for a direct interpretation of the system as being both autonomous and frictional.

Abstract
We report on infrared to visible Zeeman absorption spectroscopy and parameterised crystal-field modelling of Nd3+ centres in Y2SiO5 through the use of experimentally inferred crystal-field energy levels and Zeeman directional electronic g values. We demonstrate that good agreement between the calculated and experimental crystal-field energy levels as well as directional Zeeman g values along all three crystallographic axes can be obtained. Further, we demonstrate that the addition of correlation crystal field effects successfully account for discrepancies that arise between the calculated and experimental values relevant to the 2H

Observation of negative terahertz photoconductivity in strongly correlated electron-doped CaMnO3 thin film
Authors: Kinha Monu , Dagar Rahul , Sahoo Jayaprakash , Rakshit Rupali , Rana D S 
Published: April 2023

Abstract
Electron-doped Ca0.96Ce0.04MnO3 (CCMO) possesses a unique band structure and exhibits a giant topological Hall effect contrary to other correlation-driven manganites known for insulator-to-metal transition, magnetoresistance, complex magnetic order, etc. The interaction mechanisms among the fundamental entities and their dynamical evolutions responsible for this unusual topological phase are yet to be understood. Here, we employ time-averaged and sub-picosecond time-resolved terahertz (THz) spectroscopy to explore the low-energy steady-state and ultrafast carrier dynamics, respectively, to unravel the complexity of charge carriers during their transition from a non-equilibrium state to the ground state in CCMO thin film. The THz optical conductivity confirms the presence of dichotomic charge carriers, i.e. heavy and light carriers throughout the temperature range of 15–300 K. A rare observation of both positive and negative photoconductivities along with a sharp crossover between the two resolved to a few picoseconds of illumination confirms the formation of polaron with a lifetime of a few nanoseconds. These optical evidences of dichotomic charge carriers, along with manipulation of the sign of photoconductivity induced by dynamics of related quasiparticles could facilitate a new mechanism for ultrafast optoelectronic switching devices.
