Multi‐objective optimization of inductive power transfer system with reconfigurable topology for misalignment tolerance
Authors: Yang Junfeng , Liu Qiujiang , Yang Xu , Zhang Yanru 
Published: October 2024

AbstractAt present, most of the analyses or studies about inductive power transfer (IPT) with constant current (CC) output and constant voltage (CV) output are carried out without considering misalignment conditions or different gaps. An IPT system satisfying battery charging demand and anti‐misalignment requirements simultaneously is infrequent. This paper proposes a multi‐objective particle swarm optimization method of IPT reconfigurable topology to realize CC and CV modes at varying resistance conditions and wide coupling ranges. The output characteristics of an inductor–capacitor–capacitor (LCC)–LCC compensation circuit have been explored, and it is found that the secondary‐side compensated capacitors have a greater impact on the output power, which can be used to improve power regulation ability accompanied by coupling varying. Eight optimization compensated parameters of the reconfigurable topology are obtained from the Pareto front to achieve the required CC and CV charging outputs. By switching the compensated capacitors, the selected parameters can make the current and voltage fluctuation less than 9.3% and 7.9%, respectively, during the coupling charging range from 0.3 to 0.22. Moreover, primary zero voltage switching operation is achieved to enable high efficiency. The simulation and the experimental verification are carried out to verify the validity of the proposed method.
A soft switching non‐isolated bidirectional DC–DC converter with improved voltage conversion ratio and minimum number of switches
Authors: Madiseh Nasrin Asadi , Adib Ehsan 
Published: October 2024

AbstractA soft switching non‐isolated bidirectional DC–DC converter with an improved voltage conversion ratio without any additional auxiliary switch is presented in this paper. In the proposed converter, improved step‐up/step‐down gain conversion is achieved by employing the coupled inductors method. Also, the auxiliary circuit provides soft switching conditions for all the semiconductor elements, regardless of the power flow direction and without any extra voltage stress. The other switch helps provide soft switching conditions for the main switch. Moreover, the switch used for providing soft switching conditions operates as a synchronous rectifier as well. The additional circuit added to attain soft switching is composed of an inductor, coupled with the converter's main inductor, and two auxiliary diodes. The auxiliary diodes benefit from zero‐current‐switching conditions. Fully soft switching conditions for all semiconductor devices, removing the reverse recovery problem, and a low number of components have led to mitigating switching losses and improving efficiency. Detailed operating principles and a theoretical analysis of the proposed converter are presented. Also, the experimental results of a 220 W prototype circuit are provided to confirm the validity of the proposed topology.
An adaptive synthetic method for long sequence radar mode recognition
Authors: Chen Xiaozhou , Hu Mengzhong , Wang Xiaobo , Liu Xuanze , Lu Xiangyang 
Published: October 2024

AbstractRadar work mode recognition is crucial to analyse radar behaviour and intention. There are some challenges limiting the recognition of long sequences with multiple mode classes. First, the performance of recognition method relies on precise segregation of intercepted sequence, which is often unfeasible in reality. Second, the states at the boundaries of adjacent modes may create extraneous mode samples that intervenes the recognition. Third, current methods fail to deal with the scenarios where multiple modes share the same state sequence. To address these problems, a novel forward matching method (FMM) is proposed, comprising a shortest path method (SPM) for intra‐mode recognition, a matching strategy, and an adjustment mechanism. SPM is to provide potential recognition for short fragments of the given long sequence. The matching strategy is to assess the availability of current recognition. The adjustment mechanism tunes the segregation and improves the subsequent recognition. FMM offers several distinct advantages. First, the model can explicitly characterise the mode transition probability and is totally interpretable. Second, FMM can distinguish intentional ambiguities, alleviate mosaic ambiguity and probability deviation associated with inter‐mode recognition. Third, FMM is extendable to integrate with other intro‐mode recognition methods to cater to various scenarios.
Additively manufactured structures for precise and robust mounting of optical elements
Authors: Pfuhl Patrick , Degünther Markus 
Published: October 2024

The design freedom of Additive Manufacturing offers new opportunities for the design of mounting structures of optical systems, which are not feasible for conventional manufacturing approaches, thus opening up new areas of application for optical systems. We use this to develop a fully monolithic mounting structure for precise positioning of the optical elements, while simultaneously increasing their robustness against harsh environmental conditions. We additively manufacture such a mounting structure for an imaging lens and evaluate its optical performance with interferometric measurement of its wavefront, before and after applying a mechanical shock to the entire system. The results indicate a centering accuracy better than 6 μm, both in the initial positioning as well as the subsequent repositioning after a mechanical shock of 15G.

AbstractTo evaluate the current status of the diagnosis of gastrointestinal tumors in Germany by means of a survey of the oncological imaging working group of the German Radiological Society (DRG) with a focus on the CT protocols being used.Radiologists working in outpatient or inpatient care in Germany were invited. The survey was conducted between 10/2022 and 06/2023 using the SurveyMonkey web tool. Questions related to gastrointestinal cancer were asked with regard to the commonly used imaging modalities, body coverage, and contrast agent phases in CT as well as the use of oral or rectal contrast. The results of the survey were analyzed using descriptive statistics.Clear differences were identified regarding the acquired contrast phases in relation to the place of work – outpatient care, smaller hospitals, maximum care hospitals, or university hospitals. Variances were also recognized regarding oral and rectal contrast. Based on the results and international guidelines, proposals for CT protocols were derived.CT protocols in Germany show a heterogeneous picture regarding acquired contrast phases, as well as oral and rectal contrast for the staging of gastrointestinal cancer. Clear recommendations in the respective guidelines would aid in quality assurance and comparability between different centers.
Die „Liste Integrative Medizin“ – Integrative Medizin in jede Ärztekammer
Authors: Laube Marion 
Published: October 2024

SummaryIn den letzten Jahren wurde vielen Ärztinnen und Ärzten aus dem integrativmedizinischen Versorgungsbereich schmerzlich bewusst, wie wenig ihre Interessen in den Gremien der ärztlichen Selbstverwaltung berücksichtigt wurden. Obwohl dies die Standesvertretung für alle Ärztinnen und Ärzte sein sollte, spielen die Anliegen der komplementärmedizinisch Tätigen im berufspolitischen Alltag kaum eine Rolle. Mithilfe der "Liste Integrative Medizin (LIMed)" soll dies geändert werden. Diese Bewegung setzt sich dafür ein, integrativmedizinisch tätigen Ärztinnen und Ärzten einen Sitz und damit Mitsprache in den Ärztekammern zu sichern. Die Hufelandgesellschaft bemüht sich schon lange um ein Engagement in den ärztlichen Gremien und unterstützt die LIMed seit 2021.
Jedes Wort wirkt – die Kraft der Sprache bei der Praxisübergabe
Authors: Scheurl-Defersdorf Mechthild von 
Published: October 2024

SummarySprache spielt eine wichtige Rolle im Praxisalltag. Insbesondere im Fall einer Praxisübergabe ist es wichtig, gut zu kommunizieren - sowohl mit den Patienten als auch mit dem Praxisteam und dem nachfolgenden Arzt. Von Bedeutung ist hierbei, dass Inhalt und Form der Sprache im Einklang miteinander sind. Oft haben bereits geringfügige Änderungen der gewohnten Ausdrucksweise eine sofort spürbare positive Wirkung auf die Kommunikation und auf die eigene Ausstrahlung. Wichtige Säulen hierbei sind die eigene Präsenz im Gespräch, die Klarheit der zu übermittelnden Botschaft sowie die grundlegende Wertschätzung gegenüber dem Gesprächspartner.

Published: October 2024

Zusammenfassung
Einleitung Der Klimawandel ist die größte Bedrohung für die menschliche
Gesundheit im 21. Jahrhundert. Jahrhunderts. Der Klimawandel stellt eine
erhebliche Bedrohung für die menschliche Gesundheit in Deutschland dar, wobei
zunehmende Hitzewellen hohe Sterblichkeitsraten verursachen. In den letzten
Jahren hat sich die deutsche Ärzteschaft zunehmend mit den Folgen des
Klimawandels, insbesondere mit extremen Temperaturen und Hitze, für die
menschliche Gesundheit befasst.
Vorschläge Der Deutsche Wetterdienst (DWD) gibt zwar Hitzewarnungen
heraus, aber es fehlt an umfassenden Hitzeaktionsplänen (HAPs). Initiativen wie
das „Berliner Aktionsbündnis Hitzeschutz“ bieten sektorspezifische Pläne für
Gesundheitseinrichtungen. Im Gesundheitswesen besteht dringender
Handlungsbedarf, denn Ärztinnen und Ärzte spielen eine Schlüsselrolle bei der
Umsetzung von Hitzeschutzmaßnahmen und beim Eintreten für Maßnahmen gegen den
Klimawandel. Neben Initiativen wie der Unterzeichnung des „Klimapakts für
Gesundheit“ und der Sensibilisierung der Akteurinnen und Akteure im
Gesundheitswesen ist eine verstärkte Aufklärung über hitzebedingte
Gesundheitsrisiken unerlässlich.
Schlussfolgerung Die Ergebnisse unterstreichen die Dringlichkeit von
Maßnahmen im Gesundheitssektor angesichts des fortschreitenden Klimawandels. Die
Ärzteschaft spielt eine Schlüsselrolle bei der Umsetzung von
Hitzeschutzmaßnahmen und sollten aktiv in die Planung und Umsetzung von HAPs
einbezogen werden. Fort- und Weiterbildungen zum Thema Hitze und Gesundheit sind
im Gesundheitssektor unerlässlich. Die Registrierung für Hitzewarnungen des DWD
(www.hitzewarnungen.de) wird
empfohlen, gefolgt von der Sensibilisierung von Entscheidungsträgerinnen und –
trägern bzw. Mitarbeiterinnen und -arbeitern in Gesundheitseinrichtungen. Die
Ärzteschaft hat eine entscheidende Verantwortung bei der Umsetzung von
Hitzeschutzmaßnahmen und sollte sich aktiv positionieren und in die politische
Diskussion um Hitze und Klimawandel einbringen.

SummaryDie Gebührenordnung für Ärzte (GOÄ) deckt ärztliche Leistungen in einigen Fällen, insbesondere bei chronischen und komplexen Krankheitsbildern, nur unzureichend ab. Im Bereich der Komplementärmedizin haben Ärzte und Ärztinnen die Möglichkeit, einzelne Leistungen höher zu bewerten, wenn diese medizinisch notwendig sind und die Höherbewertung gut begründet wird. Die Deutsche Ärztegesellschaft für Akupunktur hat eine übersicht mit Begründungen erarbeitet, an denen sich Ärzte und Ärztinnen hierfür orientieren können.
Efficacy and Safety of Sodium-Glucose Cotransporter-2 (SGLT2) Inhibitor Use during Ramadan Fasting: A Systematic Review
Authors: Abdelgadir Elamin , Bashier Alaaeldin , Ashfaq Faryal , Hassanein Mohamed , Beshyah Salem A. 
Published: October 2024

Abstract
Background Religious intermittent fasting for 30 days during Ramadan may increase the risk of dehydration, hypovolemia, and hypoglycemia. These events may also be encountered when using sodium-glucose cotransporter 2 inhibitors (SGLT2is).
Objectives This article evaluates the safety of the SGLT2 inhibitors in people with type 2 diabetes during Ramadan.
Search Methods We searched PubMed CENTRAL, MEDLINE, and Google Scholar on July 25, 2023 without language restrictions.
Selection Criteria All trials assessing the safety of SGLT2 inhibitors during Ramadan were assessed and summarized into preset points.
Data Extraction Two authors independently extracted and reviewed the retrieved studies. A third author reviewed the merged summary of the two authors and modified the article when necessary.
Results Diabetic ketoacidosis, hospitalization due to diabetes-related problems, and thrombosis were either not significantly related to SGLT2i use or not studied. Estimated glomerular filtration rate (eGFR) dropped significantly in one study; otherwise, it was either not statistically significant or not studied. Hypovolemia and dehydration were significantly increased in one study only.
Conclusion From the available evidence, the use of SGLT2 inhibitors in people with diabetes during Ramadan seems to be safe and well tolerated. Hypovolemia and a drop in eGFR were reported in a few studies, with no reported clinical significance.

Abstract
Background Despite the presence of safety protocols, the manual manipulation of radiopharmaceuticals continues to pose a significant occupational radiation risk. Health care professionals in nuclear medicine are at risk of radiation exposure, particularly to their hands and eyes. Despite existing protective measures, manual handling of radiopharmaceuticals remains a significant source of occupational radiation.
Objective This study evaluates the effectiveness of automated injectors in reducing radiation exposure among health care workers during fluorine-18 fluorodeoxyglucose (18F-FDG) administrations, compared with traditional manual injection methods.
Methods We assessed radiation exposure levels associated with manual versus automated 18F-FDG injection techniques using specialized dosimeters. Measurements focused on whole-body, extremity, and eye-lens radiation doses to evaluate the potential benefits of automation in minimizing exposure.
Results Findings reveal that automated injectors significantly reduce radiation exposure, with decreases of 97.97 and 98.96% in left- and right-hand extremity doses, respectively, 43.24% in eye-lens dose, and 91.66% in whole-body dose compared with manual methods.
Conclusion Automated injection systems offer considerable advantages in reducing health care worker radiation exposure in nuclear medicine. The substantial reduction in staff doses underscores the necessity of transitioning to such technology to promote safer clinical environments. This study highlights the critical role of automation in enhancing occupational safety standards within diagnostic radiology settings.

Published: October 2024

AbstractPercutaneous transhepatic biliary procedures are essential for managing a variety of hepatobiliary conditions, particularly when endoscopic retrograde cholangiopancreatography is not feasible or has failed, or when patients are unstable. This review article provides a comprehensive overview of the indications, contraindications, and procedural steps for biliary puncture, focusing on techniques such as percutaneous transhepatic biliary drainage (PTBD) and percutaneous cholecystostomy. We also address strategies for accessing minimally dilated biliary systems and performing bedside PTBD. The article highlights the increasing demand for these interventions due to rising incidences of biliary diseases such as gallbladder cancer and cholangiocarcinoma, as well as complications arising from previous surgeries. Furthermore, we discuss common and life-threatening complications associated with these procedures, including biliary leaks, hemorrhage, and sepsis, and provide guidance on effective management strategies. Understanding these procedures and their potential complications is crucial for optimizing patient care and outcomes in complex biliary conditions.
Case Report: Alpha6 Integrin Disorder Presenting in Childhood with Nail Dysplasia and Onycholysis But No History of Fragile or Bullous Skin Changes
Authors: Zalesny Alayna N. , Gunter Sarah , Williams Charles A. 
Published: October 2024

AbstractWe report a 7-year-old girl born with pyloric atresia but without congenital epidermolysis bullosa or skin fragility. Nail dysplasia developed at age 8 months and throughout childhood she suffered from onycholysis and mild nail hypertrophy. Whole-exome sequencing demonstrated biallelic mutations in alpha6 integrin (ITGA6): p. Q139* and R153W. ITGA6 normally forms a protein heterodimer with beta4 integrin (ITGB4), and this dimer participates in anchoring the basal skin cells to the extracellular matrix. Biallelic mutations in each gene are well known to cause epidermolysis bullosa and pyloric atresia. However, this child had ostensibly normal skin without any evidence of skin fragility. In a literature search, we identified 11 cases involving ITGA6 mutations, and all had epidermolysis skin changes. Thus, this case adds to the reported phenotype of ITGA6 disease since it is the first to show absence of an epidermolysis bullosa phenotype in the setting of pyloric atresia and nail dysplasia.

Mid-infrared microscopy is an important tool for biological analyses, allowing a direct probe of molecular bonds in their low energy landscape. In addition to the label-free extraction of spectroscopic information, the application of broadband sources can provide a third dimension of chemical specificity. However, to enable widespread deployment, mid-infrared microscopy platforms need to be compact and robust while offering high speed, broad bandwidth, and high signal-to-noise ratio. In this study, we experimentally showcase the integration of a broadband, high-repetition-rate dual-comb spectrometer (DCS) in the mid-infrared range with a scanning microscope. We employ a set of 1-GHz mid-infrared frequency combs, demonstrating their capability for high-speed and broadband hyperspectral imaging of polymers and ovarian tissue. The system covers 1000 cm−1 at νc = 2941 cm−1 with 12.86 kHz spectra acquisition rate and 5 µm spatial resolution. Taken together, our experiments and analysis elucidate the trade-off between bandwidth and speed in DCS as it relates to microscopy. This provides a roadmap for the future advancement and application of high-repetition-rate DCS hyperspectral imaging.

Published: October 2024

Objective In Australia, accurate case ascertainment of acute rheumatic fever (ARF) and rheumatic heart disease (RHD) diagnoses for disease surveillance and control purposes requires the use of multiple data sources, including RHD registers and hospitalisation records. Despite drawing on multiple data sources, the true burden of ARF/RHD is likely to be underestimated. Methods This study used capture–recapture methods to quantify the missing number of ARF/RHD cases in data from hospitals and jurisdictional RHD registers. Linked datasets comprised reported cases of ARF/RHD in register records and administrative hospital data. Results Capture–recapture analyses indicated the total number of new ARF/RHD cases in three Australian jurisdictions (Queensland, South Australia and Western Australia), among people aged 3–54 years, was 3480 (95% CI = 3366–3600) during 2011–2016. This included 894 (25.7%) individuals who were not listed in either the hospital or register datasets. Non-Indigenous, urban and older people with ARF/RHD were least likely to be identified in either the hospital or register data sources. Conclusions The 894 likely ARF/RHD cases our analyses detected that are not included in the routine surveillance datasets are concerning and quantify the magnitude and characteristics of under-notification to RHD registers in Australia, especially for groups that are not typically at high risk of ARF.
How the vertical gradient of light in the understorey and water seasonality affect leaf traits of Vanilla phaeantha (Orchidaceae), a crassulacean acid metabolism (CAM) hemiephyte

Published: October 2024

Structural and physiological leaf traits and their plasticity were compared in the hemiepiphyte Vanilla phaeantha. This species grows along a phorophyte reaching different understorey positions and exhibiting diverse responses to environment changes. We analysed three height strata above the ground, establishing a light gradient, and considering seasonal water fluctuations. The upper leaves had higher area and mass and were less pigmented. The dry season induced a reduction of approximately 2 h of stomatal opening over the diel 24 h crassulacean acid metabolism (CAM) cycle in the leaves at all understorey positions. The leaves more exposed to sunlight were larger with higher titratable acidity during the rainy season, while the leaves near the ground maintained the same rates of stomatal conductance and nocturnal acidification between seasons, with lowest values of carbon isotopes in the rainy season. Our research showed that some structural leaf traits (such as specific leaf mass, biomass, and saturated water content) are sensitive to variation in understorey position. In contrast, other physiological traits (stomatal conductance, transpiration, and fluorescence parameters) are more sensitive to seasonal variations. The results are a novelty in assessing the variation of CAM along the same plant in a height gradient and under field conditions.
