Published: September 2023

AbstractA novel 1440‐V 4H‐SiC accumulation mode MOSFET (ACCUFET) with ultra‐low specific on‐resistance and improved reverse recovery performance is proposed in this article. As for the proposed SiC ACCUFET, the channel region can be completely depleted by the P‐type heavily doped polysilicon gate to build an electron barrier and realize a normally‐off device. And a Schottky barrier diode (SBD) is integrated below the trench gates on both sides, which brings the feasibility of realizing reverse conduction function of the proposed ACCUFET. Also, the p‐shield regions under the Schottky contact metal provide a good electric field shielding effect for the gate oxide. Compared with the conventional SiC trench MOSFET, the numerical simulation results show that the specific on‐resistance (Ron,sp) of the proposed ACCUFET is reduced by more than 64%. The high‐frequency figures‐of‐merit HFOM [Ron,sp × Cgd] and HFOM [Ron,sp × Qgd] of the proposed device are improved by 53.19% and 58.74%, respectively. The reverse recovery time (trr), and reverse recovery charge (Qrr) are reduced by 23.28% and 82.73%, respectively. In addition, the results also indicate that the proposed device has a better latch‐up immunity compared with the conventional SiC trench MOSFET. The excellent device performance and the simple manufacturing process provide a good prospect for the application of the proposed device.
Quasi‐Z based adaptive sliding mode control for three‐phase photovoltaic grid‐connected system

Published: September 2023

AbstractConsidering the non‐linear characteristics of both the input and output of photovoltaic (PV) modules and quasi‐Z‐source inverters, as well as the unpredictable natural factors such as large disturbances caused by changes in illumination and temperature, an average state model for the PV quasi‐Z‐source inverter is established. This paper uses the output current of photovoltaic module, DC‐link capacitor voltage and its integral as state variables, then an adaptive reaching law with second‐order sliding mode characteristics is designed by combining with power reaching law and variable speed reaching law. By using the sliding mode controller based on the adaptive reaching law to control the stability of the DC‐link voltage of the quasi‐Z‐source inverter and the small capacitor voltage ripple, the photovoltaic system can operate stably at the maximum power point when the temperature and illumination conditions change abruptly, and the grid‐connected effect is improved. Through SIMULINK and RT‐LAB real‐time simulation, the effectiveness of the proposed adaptive sliding mode control strategy is verified when the environment changes, which effectively improves the dynamic response speed and grid‐connected effect of the system, and ensures the global robustness of the grid‐connected system.
Modelling and experimental testing of an optical synchronisation beacon designed for high‐loss satellite quantum communication

Published: September 2023

AbstractLong‐distance free space quantum key distribution based on CubeSats can be used to establish global quantum secure communication networks, with potential commercial applications benefitting from the low cost of its design and launch. Detecting single‐photon level optical pulses sent from space requires highly accurate and robust timing systems to pick out signals from the noise. For such high‐loss applications, we envisage a low‐repetition (sub‐MHz) beacon laser emitting short (ns) high‐peak‐power pulses from which interpolated quantum signal arrival windows can be derived. We firstly study theoretically the effects of jitter on the efficiency of gating quantum signals including all important jitter sources, and then experimentally investigated it by changing the clock jitter, and the result shows that the greater jitter will reduce the gating rate of the signal. The experimental interpolation error is tested against loss under laboratory conditions giving results close to our model. We also found that the jitter introduced by the Doppler effect can be ignored with a repetition rate larger than 1 kHz. This model can be directly used for the performance analysis and optimisation of all quantum and non‐quantum systems using similar synchronisation schemes over terrestrial free space or fibre.

Published: September 2023

AbstractThis study addresses the challenging task of solving optimal reactive power dispatch (ORPD) while incorporating renewable energy resources (RERs), considering their stochastic and time‐varying nature. Specifically, the focus is on solving the stochastic optimal reactive power dispatch (SORPD) problem, taking into account uncertainties in load demand and generated power, as well as the reactive power generation capability of photovoltaic (PV) systems. To tackle this problem, an enhanced Artificial Gorilla Troops Optimizer (EGTO) is proposed, which utilizes multiple strategies. The objective is to minimize power loss and improve voltage profile and system stability under uncertain conditions. The algorithm is applied and tested on the IEEE 30‐bus system, both with and without the STATCOM functionality of the PV system. A comparison is conducted against other well‐known optimization algorithms. The results demonstrate the significant improvement achieved by incorporating the PV unit. The inclusion of the PV system leads to reduced expected power losses, voltage deviations, and improved voltage stability. Specifically, without and with the STATCOM functionality, the expected power loss decreases from 5.9218 MW at the base case to 1.1419 MW and 1.1197 MW, respectively. Similarly, the expected voltage deviation decreases from 1.9320 p.u. to 0.0909 p.u. and 0.0893 p.u., respectively, and the expected voltage stability decreases from 0.1336 p.u. to 0.07199 p.u. and 0.07142 p.u., respectively.

Context.This paper presents a study of the galaxy Lyman-alpha luminosity function (LF) using a large sample of 17 lensing clusters observed by the Multi Unit Spectroscopic Explorer (MUSE) at the ESO Very Large Telescope (VLT). The magnification resulting from strong gravitational lensing by clusters of galaxies and MUSE spectroscopic capabilities allows for blind detections of LAEs without any photometric pre-selection, reaching the faint luminosity regime.Aims.The present work aims to constrain the abundance of Lyman-alpha emitters (LAEs) and quantify their contribution to the total cosmic reionization budget.Methods.We selected 600 lensed LAEs behind these clusters in the redshift range of 2.9 <z< 6.7, covering four orders of magnitude in magnification-corrected Ly-αluminosity (39.0 < log(L)[erg s−1] < 43.0). These data were collected behind lensing clusters, indicating an increased complexity in the computation of the LF to properly account for magnification and dilution effects. We applied a non-parametricVmaxmethod to compute the LF to carefully determine the survey volume where an individual source could have been detected. The method used in this work follows the recipes originally developed in previous works, with some improvements to better account for the effects of lensing when computing the effective volume.Results.The total co-moving volume at 2.9 < z < 6.7 in the present survey is ∼50 103Mpc3. Our LF points in the bright end (log(L) [erg s−1] > 42) are consistent with those obtained from blank field observations. In the faint luminosity regime, the density of sources is well described by a steep slope,α ∼ −2 for the global redshift range. Up to log(L) [erg s−1] ∼ 41, the steepening of the faint end slope with redshift, suggested in earlier works, is observed, but the uncertainties are still large. A significant flattening is observed towards the faintest end, for the highest redshift bins, namely, log(L)[erg s−1] < 41.Conclusions.When taken at face value, the steep slope at the faint-end causes the star formation rate density (SFRD) to dramatically increase with redshift, implying that LAEs could play a major role in the process of cosmic reionization. The flattening observed towards the faint end for the highest redshift bins still requires further investigation. This turnover is similar to the one observed for the UV LF atz ≥ 6 in lensing clusters, with the same conclusions regarding the reliability of current results. Improving the statistical significance of the sample in this low-luminosity high-redshift regime is a difficult endeavour that may lead to potentially valuable leads in understanding the process of reionization.
S1 Guideline: Impairment of gonadal function After Cancer in
Childhood and Adolescence

Published: September 2023

AbstractA possible negative consequence of cancer treatment is the fertility impairment
of young cancer survivors. However, most former patients express the wish to
have biological children. Fertility-preserving measures are available and are
– under certain circumstances – financed by health insurance.
Separate information at the time of diagnosis and during follow-up care should
be adapted to the individual risk and enable those affected to make a
self-determined decision about cryopreservation of germ cells or germ cell
tissue. Hyopgonadotropic hypogonadism can be treated by the pulsatile
administration of gonadotropins. Affected individuals can be reassured. A health
restriction of the offspring due to the cancer treatment is not to be expected,
even after artificial insemination.

Published: September 2023

Abstract
Background Potentially inappropriate medications (PIMs) are frequently
prescribed to older people with diabetes. This study aimed to assess the
prevalence of PIM use in older people with diabetes and identify potential risk
factors influencing the development of PIM use.
Methods This was a cross-sectional study conducted in an outpatient
setting in Beijing, China, using Chinese criteria. The prevalence of PIM use,
polypharmacy, and comorbidities in older adults with diabetes in an outpatient
setting was measured. Logistic models were employed to investigate the
association among polypharmacy, comorbidities, and PIM use.
Results The prevalence of PIM use and polypharmacy was 50.1% and
70.8%, respectively. The most common comorbidities were hypertension
(68.0%), hyperlipemia (56.6%), and stroke (36.3%), and
the top three inappropriately used medications were insulin (22.0%),
clopidogrel (11.9%), and eszopiclone (9.81%). Age (OR 1.025;
95% CI 1.009, 1.042), the number of diagnoses (OR 1.172; 95% CI
1.114, 1.232), coronary heart disease (OR 1.557; 95% CI 1.207, 2.009),
and polypharmacy (OR 1.697; 95% CI 1.252, 2.301) were associated with
PIM use.
Conclusions Given the higher rate of PIM use among older adults with
diabetes, strategies and interventions targeting this population are needed to
minimize PIM use.

Published: September 2023

Abstract
Purpose To compare two glaucoma drainage devices with subconjunctival filtration (MicroShunt and XEN) for open-angle glaucoma (OAG), with respect to effectiveness and safety.
Patients and Methods This is a single center, retrospective, interventional study. In total, 106 eyes of 95 patients with OAG underwent surgery. Of these patients, 51 eyes of 45 patients received a MicroShunt implantation and 55 eyes of 50 patients received an XEN implantation. Failure was defined as an intraocular pressure (IOP) lower than 5 or higher than 17 mmHg at the end of follow-up after 2 years, the need for surgical revision, secondary glaucoma surgery, or loss of light perception. Outcome was rated as complete success or qualified success, depending on whether it was achieved with or without anti-glaucomatous medications. Postoperative complications and interventions were also documented for both groups.
Results In the MicroShunt group, mean IOP decreased from 20.6 ± 7.5 mmHg at baseline to 13.0 ± 3.9 mmHg (p < 0.0001) after 2 years. In the XEN group, mean IOP was lowered from 22.5 ± 7.9 mmHg to 13.5 ± 4.2 mmHg (p < 0.0001). In both groups, the mean number of medications was significantly reduced (MicroShunt 2.7 ± 1.2 to 0.9 ± 2.5; p < 0.0001 vs. XEN 3.2 ± 0.9 to 1.1 ± 1.5; p < 0.0001). In regard to success rates, 37% of MicroShunt patients achieved complete success and 57% qualified success at the end of follow-up. In the XEN group, rates were 25 and 45%, respectively. Patient demographics differed between the two groups with respect to age (MicroShunt 72.8 ± 8.7 vs. XEN 67.7 ± 9.0 years; p = 0.002). Postoperative complications were comparable between the two groups.
Conclusion Both MicroShunt and XEN are effective in significantly reducing IOP and glaucoma medications in OAG, and with a good safety profile.

Published: September 2023

Abstract
Background The possibility of coil dislocation in computed tomography (CT)-guided microcoil localization of superficial pulmonary nodules is relatively high. The aim of the study is to investigate the outcomes of deeper localization technique during CT-guided microcoil localization of superficial pulmonary nodules before video-assisted thoracoscopic surgery (VATS).
Methods Fifty-seven identified superficial pulmonary nodules (nodule–pleural distance ≤ 1 cm on CT image) from 51 consecutive patients underwent CT-guided microcoil localization, and subsequent VATSs were included. The rate of technical success, complications, and excised lung volume were compared between deeper localization technique group and conventional localization technique group.
Results The technical success rate of the localization procedure was 100% (25/25) in the deeper localization group and 81.3% (26/32) in the conventional localization group (p = 0.030). Excluding one case of lobectomy, the excised lung volume in the deeper localization group and the conventional localization group was 39.3 ± 23.5 and 37.2 ± 16.2 cm3, respectively (p = 0.684). The incidence of pneumothorax was similar between the deeper localization group and the conventional localization group (24.0 vs. 21.9%, respectively, p = 0.850). The incidence of intrapulmonary hemorrhage in the deeper localization group was higher (16.0%) than that in the conventional localization group (6.3%), but the difference was not statistically significant (p = 0.388).
Conclusion CT-guided microcoil localization of superficial pulmonary nodules prior to VATS using a deeper localization technique is feasible. Deeper localization technique reduced the occurrence of dislocation but did not increase excised lung volume.

Abstract
Background Walled-off necrosis (WON) is highly morbid disease most effectively managed by endoscopic drainage with lumen-apposing metal stents (LAMSs) or plastic stents, with or without necrosectomy. This meta-analysis compared the clinical outcomes of patients included in randomized trials treated using LAMSs or plastic stents.
Methods The MEDLINE and EMBASE databases were searched to identify all data collected from randomized trials comparing LAMSs and plastic stents for the treatment of WON. The primary outcome measure was need for endoscopic necrosectomy.
Results Three studies comprising 206 patients met inclusion criteria. Except for procedure duration, which was significantly shorter for LAMSs (standardized mean difference [SMD] −1.22, 95%CI −1.64 to −0.79), there was no significant difference in need for necrosectomy (38.5% vs. 41.2%; risk ratio [RR] 1.07, 95%CI 0.79–1.45), number of interventions (SMD −0.09, 95%CI −0.40 to 0.22), treatment success (90.7% vs. 94.5%; RR 0.96, 95%CI 0.87–1.06), recurrence (4.6% vs. 0.6%; RR 3.73, 95%CI 0.42–33.0), readmission (42.6% vs. 50.2%; RR 0.84, 95%CI 0.62–1.14), length of hospitalization (SMD −0.06, 95%CI −0.55 to 0.43), mortality (8.5% vs. 9.8%; RR 0.70, 95%CI 0.30–1.66), new-onset organ failure (10.6% vs. 14.6%; RR 0.72, 95%CI 0.16–3.32), bleeding (11.0% vs. 10.7%; RR 1.09, 95%CI 0.34–3.44), procedural adverse events (23.6% vs. 19.2%; RR 1.38, 95%CI 0.82–2.33), or overall costs (SMD −0.04, 95%CI −0.31 to 0.24) between LAMSs and plastic stents, respectively.
Conclusions Except for procedure duration, there is no significant difference in clinical outcomes for patients with WON treated using LAMSs or plastic stents.

Authors: Bhatia Nisha , Dhingra Vandana K. , Mittal Pulkit , Saini Sunil 
Published: September 2023

Abstract
Objective Our objective was to study the radiation exposure rate as function of time in the administration of radioiodine iodine-131 (I-131) for the treatment of thyrotoxicosis or Graves' disease and remnant ablation on an outpatient basis at the Department of Nuclear Medicine, and also, to study the impact of revised discharge criteria for radioiodine therapy enforced by the Atomic Energy Regulatory Board (AERB) of India.
Materials and Methods This study included patients who underwent low-dose radioiodine therapy using I-131. Patients were classified into two different groups, that is, group A and group B. Group A included patients receiving low dose I-131 for the treatment of thyrotoxicosis, whereas group B included patients receiving I-131 therapy for the ablation of residual thyroid tissue after total thyroidectomy. The radiation exposure rate was measured using a radiation detector in milli roentgen per hour (mR/h) at 5 cm distance of stomach and neck levels and with the patient standing at the distance of 1 m after oral administration of I-131 at 0, 1, and 2 hours.
Results A total of 134 (17 males and 117 females) patients were included in the study. Group A comprised 102 (14 male and 88 females) patients and group B of 32 (3 males and 29 females) patients. At the neck level, the average exposure rate in group A versus group B after 0, 1, and 2 hours was observed to be 6.9 versus 22.27 mR/h, 33.67 versus 43.39 mR/h, and 41.75 versus 48.90 mR/h, respectively. At the stomach level, the exposure rate was 23.65 versus 71.32 mR/h, 13.27 versus 48.45 mR/h, and 9.91 versus 39.43 mR/h after 0, 1, and 2 hours, respectively. At a distance of 1 m, the exposure rate was 1.31 versus 2.99 mR/h, 1.05 versus 2.58 mR/h, and 0.92 versus 2.21 mR/h, respectively.
Conclusion Exposure rate measured for patients treated with up to 1,110 MBq (30 mCi) of I-131 was under permissible limits as per revised discharged limits, that is, 50 µSv/h (5 mR/h) prescribed by AERB, India. The patients undergoing radioiodine therapy I-131 (up to 1,110 MBq/30 mCi) can be discharged safely 2 hours postadministration following good work practice along with providing proper radiation safety instructions to patients.
