Published: September 2022

AbstractPermanent magnet eddy current couplers have been widely used in large fan and pump loads to achieve the purpose of speed regulation and energy saving. In order to reduce the coupler axial volume and simplify the actuator, a novel flux adjustable axial flux permanent magnet eddy current coupler (FAAF‐PMECC) is proposed in this paper. The permanent magnet rotor is divided into three parts: the inner, middle and outer parts, where the permanent magnets are embedded in the core and the adjacent poles are magnetised in opposite directions. The middle part is the adjusting permanent magnet ring (AR), which can rotate around the shaft. The inner part and outer part are fixed permanent magnet rings (FR) that are fixed with the shaft, and the output torque can be controlled by adjusting the relative angle of AR and FR. The structure and working principle of FAAF‐PMECC are described in detail, and the output torque analytical model of the whole regulating process is established based on the magnetic equivalent circuit method. The AR regulation process is simulated by the variable reluctance model. The validation results show that the proposed structure can achieve a good speed regulation effect, and the output torque calculated by the analytical model in a certain slip speed range matches well with the output torque obtained using the 3D finite element method and experimental measurements. The sensitivity analysis of the structure parameters is also carried out. The analysis shows that the proposed coupler can achieve a wide speed range.

AbstractHair is the most important but onerous step for depicting dynamic 3D virtual characters. The photorealistic hair animation requires high‐quality simulation and rendering models. These models are based on complex calculations of mechanics and optics. Because of the huge time budget, it is difficult to apply in the interactive scene. A promising solution to overcome the time budget is the reduced model that struggles to reduce the computation of physical details by various interpolation methods. However, current reduced models compromise too much reality. This research intends to achieve photorealistic hair animation in a fast way. Building a deep learning‐based framework to synthesize photorealistic hair is aimed at. Furthermore, this research also presents a pipeline for hair merging into the scene. This new framework enables the model to significantly improve the appearances of hair animation while adding little computation overhead.

Published: September 2022

AbstractWith the increase in penetration of wind generation on interconnected power systems, the importance of wind power ramp forecasting has continuously grown. Large power ramps caused by sudden weather changes raise more concerns due to their significant impact on the power system economics and stability. Correct wind power ramp forecasts can help the system operators and utility companies to tradeoff the risks when scheduling wind energy in the electricity market. In this paper, a day‐ahead wind power ramp forecasting algorithm is developed to provide probabilistic ramp forecasts for look‐ahead times up to 48 h using hourly wind speed forecasts from Environment Canada High Resolution Deterministic Prediction System (HRDPS). An image‐based similarity search strategy has been designed to build a direct link between the wind speed forecasts and the wind power ramp prediction, thus reducing the impact of the uncertainty from both the power production forecast model and the ramp identification process on the forecasting accuracy. A performance assessment and validation of the proposed ramp event forecasting method is conducted by using the forecast and operation data from six investigated wind farms across Canada.

Context. Infrared spectroscopy over a wide spectral range and at the highest resolving powers (R > 70 000) has proved to be one of the leading techniques to unveil the atmospheric composition of dozens of exoplanets. The recently upgraded spectrograph CRIRES instrument at the Very Large Telescope (CRIRES+) was operative for a first science verification in September 2021, and its new capabilities in atmospheric characterization were ready to be tested.
Aims. We analyzed transmission spectra of the hot Saturn WASP-20b in the K band (1981–2394 nm) that were acquired with CRIRES+ with the aim to detect the signature of H2O and CO.
Methods. We used a principal component analysis to remove dominant time-dependent contaminating sources such as telluric bands and the stellar spectrum. We extracted the planet spectrum by cross-correlating observations with 1D and 3D synthetic spectra, without circulation.
Results. We present the tentative detection of molecular absorption from water vapor at a signal-to-noise ratio equal to 4.2 and 4.7 by using only H2O 1D and 3D models, respectively. The peak of the cross-correlation function occurred at the same rest-frame velocity for both model types (Vrest = −1 ± 1 km s−1 ) and at the same projected orbital velocity of the planet, but with different error bands (1D model: Kp = 131 −29+18 k ms −1; 3D: Kp = 131 −39+23 k ms −1). Our results agree with the result expected in the literature (132.9 ± 2.7 km −1).
Conclusions. Although the observational conditions were not ideal and we had problems with the pipeline in calibrating and reducing our raw data set, we obtained the first tentative detection of water in the atmosphere of WASP-20b. We suggest a deeper analysis and additional observations to confirm our results and unveil the presence of CO.

AbstractIntroduction Perinatal depression (PND) is a frequently observed mental disorder, showing a prevalence of up to 20% and resulting in unfavorable maternal and neonatal outcomes. Targeted screening for PND offers the potential to identify and treat undiagnosed cases and help prevent its deleterious consequences. The aim of the present study was to evaluate participantsʼ personal attitudes and acceptance of a routine screening program for PND in pregnancy care, identify any potential underlying factors, and appraise the general perspective on perinatal mental health problems.Methods In total, 732 women in their second trimester of pregnancy took part in a PND screening program that was incorporated in routine prenatal care using the Edinburgh Postnatal Depression Scale (EPDS) and completed a web-based survey on screening acceptance.Results Participants viewed PND screening as useful (78.7%, n = 555/705), especially in terms of devoting attention to perinatal mental health problems (90.1%, n = 630/699), easy to complete (85.4%, n = 606/710), and without feelings of discomfort (88.3%, n = 628/711). Furthermore, women with previous or current mental health issues rated the usefulness of screening significantly higher, as did women with obstetric risks (p < 0.01 – p = 0.04). The final regression model explained 48.4% of the variance for screening acceptance.Conclusion Patient acceptance for PND screening was high in our study cohort, supporting the implementation of screening programs in routine pregnancy care with the potential to identify, sensitize, and treat undiagnosed patients to reduce stigmatization and offer access to tailored dedicated PND care programs.

AbstractThe recommendations of the AGO Breast Committee on the surgical therapy of breast cancer were last updated in March 2022 (www.ago-online.de). Since surgical therapy is one of several partial steps in the treatment of breast cancer, extensive diagnostic and oncological expertise of a breast surgeon and good interdisciplinary cooperation with diagnostic radiologists is of great importance. The most important changes concern localization techniques, resection margins, axillary management in the neoadjuvant setting and the evaluation of the meshes in reconstructive surgery. Based on meta-analyses of randomized studies, the level of recommendation of an intraoperative breast ultrasound for the localization of non-palpable lesions was elevated to “++”. Thus, the technique is considered to be equivalent to wire localization, provided that it is a lesion which can be well represented by sonography, the surgeon has extensive experience in breast ultrasound and has access to a suitable ultrasound device during the operation. In invasive breast cancer, the aim is to reach negative resection margins (“no tumor on ink”), regardless of whether an extensive intraductal component is present or not. Oncoplastic operations can also replace a mastectomy in selected cases due to the large number of existing techniques, and are equivalent to segmental resection in terms of oncological safety at comparable rates of complications. Sentinel node excision is recommended for patients with cN0 status receiving neoadjuvant chemotherapy after completion of chemotherapy. Minimally invasive biopsy is recommended for initially suspect lymph nodes. After neoadjuvant chemotherapy, patients with initially 1 – 3 suspicious lymph nodes and a good response (ycN0) can receive the targeted axillary dissection and the axillary dissection as equivalent options.

Published: September 2022

Background and study aims Training in endoscopy is a key objective of gastroenterology residency. There is currently no standardized or systematic training approach. This study evaluated and compared the current status of gastrointestinal endoscopy training programs in all teaching hospitals in the Netherlands from a resident perspective.
Materials and methods A national online survey with open and closed questions on gastrointestinal endoscopy training was administered to all gastroenterology residents (N = 180) in the eight educational regions in the Netherlands.
Results One hundred residents who had already started endoscopy training were included in the analyses. Sixty-five residents (65 %) were satisfied with their endoscopy training program. Participation in a preclinical endoscopy course was mandatory in seven of eight educational regions. Residents from the region without a mandatory endoscopy training course were significantly less likely to be satisfied with their endoscopy training program (32 %, P = .011). Criteria used to determine the level of supervision differed greatly between teaching hospitals (e. g. assessed endoscopy competence, predefined period of time or number of procedures). Only 26 residents (26 %) reported uniformity in teaching methods and styles between different supervising gastroenterologists in their teaching hospital.
Conclusions Although most gastroenterology residents were satisfied with the endoscopy training program and endoscopy supervision in their teaching hospital, this study identified considerable local and regional variability. Future studies should be conducted to evaluate the trainers’ perspective and trainers’ behavior during endoscopy training sessions, which might eventually lead to the development of best practices regarding endoscopy training, including standardization of training programs and supervision methods.

Abstract
Background and study aims Intussusception caused by intestinal polyps in patients with Peutz-Jeghers syndrome usually requires laparotomy. Patients following successful endoscopic reduction using double-balloon endoscopy (DBE) have been reported. The aim of this study was to evaluate the feasibility of endoscopic treatment of intussusception.
Patients and methods We retrospectively reviewed patients who underwent DBE for intussusception due to small intestine polyps in patients with Peutz-Jeghers syndrome from January 2004 to June 2020.
Results Twenty-seven (antegrade 22, retrograde 5) DBEs were performed in 19 patients with 25 sites of intussusception identified during the study period. If the intussusception remained once the endoscope reached the site, endoscopic reduction of the intussusception was performed as needed (15 sites). Ultimately, endoscopic resections (8 sites) or ischemic polypectomies (16 sites) of the polyp causing the intussusception were completed at 24 sites. Only one site could not be treated endoscopically and was treated surgically. The final per-site and per-patient success rates of endoscopic treatment were 96 % (24/25) and 95 % (18/19) respectively. Two patients developed mild acute pancreatitis and one patient developed intussusception after the procedures, both of which were treated non-operatively.
Conclusions Endoscopic treatment of intussusception is feasible to avoid laparotomy in patients with Peutz-Jeghers syndrome.

Abstract
Importance A same-day ophthalmic urgent care clinic can provide efficient eye care, a rich educational environment, and can improve patient experience.
Objective The aim of this study was to systematically evaluate volume, financial impact, care metrics, and the breadth of pathology of urgent new patient encounters based on their site of initial presentation.
Design, Setting, and Participants A retrospective analysis was performed on consecutive urgent new patient evaluations in our same-day triage clinic at the Henkind Eye Institute at Montefiore Medical Center between February 2019 and January 2020. The cohort of patients who presented directly to this urgent care clinic were referred to as the “TRIAGE” group. Patients who initially presented to an emergency department (ED), and were subsequently referred to our triage clinic, are referred to as the “ED + TRIAGE” group.
Main Outcomes and Measures Visits were evaluated on a variety of metrics, including diagnosis, duration, charge, cost, and revenue. Furthermore, return to the ED or inpatient admission was documented.
Results Of 3,482 visits analyzed, 2,538 (72.9%) were in the “TRIAGE” group. Common presenting diagnoses were ocular surface disease (n = 486, 19.1%), trauma (n = 342, 13.5%; most commonly surface abrasion n = 195, 7.7%), and infectious conjunctivitis (n = 304, 12.0%). Patients in the “TRIAGE” group, on average, were seen 184.6% faster (158.2 vs. 450.2 minutes) than patients in the “ED + TRIAGE” group (p < 0.001). The “ED + TRIAGE” group were furthermore found to generate 442.1% higher charges ($870.20 vs. 4717.70) and were associated with 175.1% higher cost ($908.80 vs. 330.40) per patient. The hospital was found to save money when noncommercially insured patients with ophthalmic complaints presented to the triage clinic instead of the ED. Patients seen in the triage clinic had a low rate of readmission to the ED (n = 42, 1.2%).
Conclusions and Relevance A same-day ophthalmology triage clinic provides efficient care, while providing a rich learning environment for residents. Less wait time with direct access to subspecialist care can help improve quality, outcome, and satisfaction metrics.
Homoeopathic Medicine Teucrium marum varum in Treatment of Nasal Polyps Associated with Chronic Rhinosinusitis: A Case Report
Authors: Bhattacharjee Baidurjya , Dutta Abhijit 
Published: September 2022

AbstractBackground Nasal polyps are one of the most prevalent and significant clinical problems. No suitable therapy has been identified except surgical intervention, which is also associated with a high chance of recurrence.Case This article reports two cases presented primarily with nasal polypus. The prescription of Teucrium marum varum was made specifically based on the location of the polyps. In the first case, there was prompt relief of the symptoms. But in the second case, non-individualised specific application of the remedy could not relieve the patient of his symptoms. Relief was obtained by giving medicines based on the indicated characteristic symptom. Both the cases were followed up for an additional 6 months following the total disappearance of symptoms to rule out any recurrence.Conclusion Specific remedies act very conditionally depending on the presenting characteristics and peculiarities of the case. Therefore, depending solely on the specific medicines for any disease condition is not advised. Causal attribution cannot be drawn from case reports but shows a direction for consideration of homoeopathic specifics in such cases. Adequately controlled trials with rigorous methodology are required to prove the efficacy beyond doubt.

Nation branding vs. nation building revisited: Ukrainian information management in the face of the Russian invasion
Authors: Bolin Göran , Ståhlberg Per 
Published: September 2022

AbstractThis article re-evaluates some of the previous assumptions made related to the communication practices and information management in Ukraine since before the Euromaidan revolution in 2013. We highlight two points where previous knowledge about nation branding and nation building must be rethought in light of the latest developments Firstly, nation branding is no longer exclusively an activity that is directed to an audience of foreign investors and tourists, but also toward the international field of politics. Simultaneously, it is also clearly directed toward a domestic audience—the citizens of Ukraine. Secondly, this means that there may no longer be any sharp distinction between nation building and nation branding—at least not in times of an ongoing armed conflict.

Published: September 2022

The Aerosol Interaction and Dynamics in the Atmosphere (AIDA) cloud expansion chamber with a volume of 84 m3 was extended for the small cloud expansion chamber AIDA mini (AIDAm) with a volume of 20 L. AIDAm is located in the cold room of AIDA and can perform automated ice-nucleation measurements over longer time periods of hours to days. AIDAm samples from the AIDA chamber, which acts as a reservoir of atmospheric aerosol types, which can slowly be modified by physical or chemical processes similar to those occurring in the atmosphere. AIDAm was validated for accurate ice-nucleation temperature control by measuring homogeneous freezing of pure water droplets at temperatures around −34 °C and for immersion freezing induced by dust aerosol particles in the temperature range between −20 and −30 °C. Further validation experiments at cirrus cloud temperatures of −45 °C revealed that AIDAm can distinguish between heterogeneous ice formation on mineral dust aerosols and homogeneous freezing of sulfuric acid solution particles. The contribution of homogeneous and heterogeneous ice formation processes to the ice-nucleation activity of coated dust particles was investigated in a 7 h long experiment, where solid dust particles were slowly coated with sulfuric acid. The continuous AIDAm measurements with a time resolution of 6 min showed a substantial suppression of the heterogeneous freezing phenomenon and an increasing role of homogeneous freezing while the coating amount was slowly increased. This experiment proved the capability of AIDAm to sensitively detect small changes in the ice-nucleation ability of aerosols, which undergo slow processing like chemical surface coating.
Use of a Mylar filter to eliminate vacuum ultraviolet pulse pileup in low-energy x-ray measurements

Published: September 2022

We describe a method to reduce vacuum ultraviolet (VUV) pulse pileup (PPU) in x-ray pulse-height Silicon Drift Detector (SDD) signals. An Amptek FAST SDD, with C1 (Si3N4) window, measures bremsstrahlung emitted from PFRC-2 plasma to extract the electron temperature (Te) and density (ne). The C1 window has low transmissivity for photons with energy below 200 eV though will transmit some VUV and soft x-ray photons, which PFRC-2 plasmas abundantly emit. Multi-VUV-photon PPU contaminates the interpretation of x rays with energy &gt; 100 eV, particularly in a low-energy exponential tail. The predicted low transmissivity of ∼1 μm thick Mylar [polyethylene terephthalate (PET)] to photons of energy &lt;100 eV led to the selection of Mylar as the candidate filter to reduce VUV PPU. Experiments were conducted on an x-ray tube with a graphite target and on a quasi-Maxwellian tenuous plasma (ne ∼ 109 cm−3) with effective temperatures reaching 1500 eV. A Mylar filter thickness of 850 nm is consistent with the results. The Mylar-filter-equipped SDD was then used on the PFRC-2 plasma, showing a substantial reduction in the low-energy x-ray signal, supporting our hypothesis of the importance of VUV PPU. We describe the modeling and experiments performed to characterize the effect of the Mylar filter on SDD measurements.
