Published: May 2024

AbstractIn a modular multilevel converter (MMC) system, the sub‐module (SM) capacitors account for a large proportion of cost, volume and weight. Increasing modulation index (m) is an effective method to reducing the capacitance. Traditional MMC based on half‐bridge SM (HBSM) cannot boosting m while the hybrid MMC composed of HBSMs and full‐bridge sub‐modules (FBSM) can increase the m. The negative voltage is required when hybrid MMC works at the boosted m, which is only provided by the FBSMs because the HBSMs cannot output negative voltage. Therefore, appropriate control strategies are needed to achieve the normal operation of hybrid MMC under boosted m. This paper presents a control method suitable for hybrid MMC with high m based on multi‐harmonic voltage injection. The m is increased to 1.41 with the proposed multi‐harmonic voltage injection. Compared with the HBSM‐MMC, the proposed method reduces the total capacitance by more than 32%. Boosting m also reduces the RMS and peak value of the arm current by 18%. A comprehensive comparison was presented to demonstrate the cost and effect. Simulation and experiment verified the proposed method.

Context. Understanding the gas content in galaxies, along with its consumption and replenishment, is vital to our grasp of the evolution of the Universe. Numerous studies have addressed this notion, utilizing various observational tools and analytical methods. These include examining low-transition 12CO millimeter rotational lines and exploring the far-infrared and the (sub-)millimeter emission of galaxies. With the capabilities of present-day facilities, much of this research has been centered on relatively bright galaxies.
Aims. This study is aimed at exploring the gas reservoirs of a more general type of galaxy population at 1.0 < z < 3.0 that is not restricted to bright (sub-)millimeter objects. We strive to obtain a measurement that will help to constrain our knowledge of the gas content at 1010 − 11 M⊙, with upper limits at ∼108 − 10 M⊙.
Methods. We stacked ALMA 1.1 mm data to measure the gas content of a mass-complete sample of galaxies down to ∼108.6 M⊙ at z = 1 (∼109.2 M⊙ at z = 3) extracted from the HST/CANDELS sample in GOODS-S. The selected sample is composed of 5530 predominantly blue (⟨b − i⟩∼0.12 mag, ⟨i − H⟩∼0.81 mag), star-forming main sequence (MS) objects (ΔMS = log SFR−log SFRMS ∼ −0.03 dex).
Results. At 1010 − 11 M⊙, our gas fractions (fgas = Mgas/(Mgas + M⋆)), ranging from 0.32 to 0.48 at these redshifts, are in good agreement with other studies based on mass-complete samples down to 1010 M⊙. These values are, however, lower than expected, according to other works more biased to individual detections. At 109 − 10 M⊙, we obtained 3σ upper limits for the fgas values ranging from 0.69 to 0.77. At 108 − 9 M⊙, these upper limits rise to ∼0.97. The upper limits at 109 − 10 M⊙ are on the level of the extrapolations of scaling relations based on mass-complete samples and below those based on individual detections. As such, these results suggest that the gas content of low-mass galaxies is, at most, equivalent to what has been extrapolated from the literature scaling relations based on mass-complete samples down to 1010 M⊙. Overall, the comparison of our results with the literature reflects how the inclusion of bluer, less obscured, and more MS-like objects progressively pushes the gas content down to lower values.

Aims. We report the confirmation of a new transiting exoplanet orbiting the star TOI-5076.
Methods. We present our vetting procedure and follow-up observations which led to the confirmation of the exoplanet TOI-5076b. In particular, we employed high-precision TESS photometry, high-angular-resolution imaging from several telescopes, and high-precision radial velocities from HARPS-N.
Results. From the HARPS-N spectroscopy, we determined the spectroscopic parameters of the host star: Teff = (5070±143) K, log 𝑔 = (4.6±0.3), [Fe/H] = (+0.20±0.08), and [α/Fe] = 0.05±0.06. The transiting planet is a warm sub-Neptune with a mass mp = (16±2) M⊙, a radius rp =(3.2±0.l) R⊙ yielding a density ρp = (2.8±0.5) g cm−3. It revolves around its star approximately every 23.445 days.
Conclusions. The host star is a metal-rich, K2V dwarf, located at about 82 pc from the Sun with a radius of R⋆ = (0.78±0.01) R⊙ and a mass of M⋆ = (0.80±0.07) M⊙. It forms a common proper motion pair with an M-dwarf companion star located at a projected separation of 2178 au. The chemical analysis of the host-star and the Galactic-space velocities indicate that TOI-5076 belongs to the old population of thin-to-thick-disk transition stars. The density of TOI-5076b suggests the presence of a large fraction by volume of volatiles overlying a massive core. We found that a circular orbit solution is marginally favored with respect to an eccentric orbit solution for TOI-5076b.

Published: May 2024

Context. Asteroids preserve important information about the origin and evolution of the Solar System. Three-dimensional (3D) surface models of asteroids are essential for exploration missions and scientific research. Regular methods for 3D surface reconstruction of asteroids, such as stereo-photogrammetry (SPG), usually struggle to reconstruct textureless areas and can only generate sparse surface models. Stereo-photoclinometry (SPC) can reconstruct pixel-wise topographic details but its performance depends on the availability of images obtained under different illumination conditions and suffers from uncertainties related to surface reflectance and albedo.Aims. This paper presents Asteroid-NeRF, a novel deep-learning method for 3D surface reconstruction of asteroids that is based on the state-of-the-art neural radiance field (NeRF) method.Methods. Asteroid-NeRF uses a signed distance field (SDF) to reconstruct a 3D surface model from multi-view posed images of an asteroid. In addition, Asteroid-NeRF incorporates appearance embedding to adapt to different illumination conditions and to maintain the geometric consistency of a reconstructed surface, allowing it to deal with the different solar angles and exposure conditions commonly seen in asteroid images. Moreover, Asteroid-NeRF incorporates multi-view photometric consistency to constrain the SDF, enabling optimised reconstruction.Results. Experimental evaluations using actual images of asteroids Itokawa and Bennu demonstrate the promising performance of Asteroid-NeRF, complementing traditional methods such as SPG and SPC. Furthermore, due to the global consistency and pixel-wise training of Asteroid-NeRF, it produces highly detailed surface reconstructions. Asteroid-NeRF offers a new and effective solution for high-resolution 3D surface reconstruction of asteroids that will aid future exploratory missions and scientific research on asteroids.
Phänotypische Klassifizierung der Kardiomyopathien entsprechend den Leitlinien der ESC 2023

Published: May 2024

ZusammenfassungKardiomyopathien sind Herzmuskelerkrankungen mit struktureller und funktioneller Myokardstörung. Die ESC hat 2023 erstmals eine internationale Leitlinie zum gesamten Spektrum der Kardiomyopathien herausgebracht. Ein zentrales Element der Leitlinie ist die phänotypische Klassifizierung der Kardiomyopathien. Hierbei spielt neben morphologischen und funktionellen Merkmalen als wesentliche Neuerung auch die genaue Gewebecharakterisierung (z. B. Narbenbildung) basierend auf einer kardialen Magnetresonanztomografie (CMR) eine wesentliche Rolle. Auf dieser Grundlage erfolgt die phänotypische Einteilung in 5 Hauptformen. Zusätzlich zur dilatativen, hypertrophen und restriktiven Kardiomyopathie (DCM, HCM und RCM) wurde die nicht dilatierte linksventrikuläre Kardiomyopathie (NDLVC) neu definiert. Ferner wurde die Gruppe der arrhythmogenen rechtsventrikulären Kardiomyopathie (ARVC) aktualisiert. Die hiermit definierten Kardiomyopathie-Phänotypen sollen die Ermittlung der genauen Ätiologie vereinfachen.
Myokardiale Hypertrophie – von dem klinischen Phänotyp zur Diagnose einer hypertrophen Kardiomyopathie

Published: May 2024

ZusammenfassungDie myokardiale Hypertrophie beschreibt einen klinischen und bildmorphologischen Phänotyp, der auf verschiedene Ätiopathogenesen zurückzuführen ist. Sie kann sich als sekundäre Anpassungsreaktion auf abnormale Druckverhältnisse manifestieren oder im Rahmen von primären Erkrankungen auftreten, die direkt die Kardiomyozyten oder das Myozytennetzwerk betreffen. Die hypertrophe Kardiomyopathie repräsentiert dabei eine eigenständige Krankheitsentität.In der kardiologischen Praxis ist es entscheidend, die heterogenen Ursachen des hypertrophen Phänotyps zu differenzieren und unterschiedliche diagnostische Wege initiieren zu können. Hierbei ist eine umfassende Basisdiagnostik mittels Anamnese, Elektrokardiografie, Echokardiografie und weiterführende Bildgebungen von Bedeutung, um eine gezielte Differenzierung zu ermöglichen. Eine präzise Diagnose ist entscheidend für die Risikoeinschätzung und gezielte therapeutische Intervention.

AbstractIn recent years, new targeted therapies have been developed to treat patients with hormone receptor-positive (HR+)/human epidermal growth factor receptor 2-negative (HER2−) breast cancer. Some of these therapies have not just become the new therapy standard but also led to significantly longer overall survival rates. The cyclin-dependent kinase 4 and 6 inhibitors (CDK4/6i) have become the therapeutic standard for first-line therapy. Around 70 – 80% of patients are treated with a CDK4/6i. In recent years, a number of biomarkers associated with progression, clonal selection or evolution have been reported for CDK4/6i and their endocrine combination partners. Understanding the mechanisms behind treatment efficacy and resistance is important. A better understanding could contribute to planning the most effective therapeutic sequences and utilizing basic molecular information to overcome endocrine resistance. One study with large numbers of patients which aims to elucidate these
mechanisms is the Comprehensive Analysis of sPatial, TempORal and molecular patterns of ribociclib efficacy and resistance in advanced Breast Cancer patients (CAPTOR BC) trial. This overview summarizes the latest clinical research on resistance to endocrine therapies, focusing on CDK4/6 inhibitors and discussing current study concepts.

ZusammenfassungDie Implantation einer Knieendoprothese zählt mit ca. 170000 Eingriffen pro Jahr zu den am häufigsten stationär durchgeführten Operationen in Deutschland. Eine einheitliche, angemessene und patientenorientierte ärztliche Indikationsstellung ist bei einem solchen Eingriff unerlässlich. Das Update der S2k-Leitlinie „Indikation Knieendoprothese“ beinhaltet auf aktueller Evidenz basierende und im breiten Konsens abgestimmte Empfehlungen und eine Checkliste im praxistauglichen Format.Für dieses Leitlinien-Update wurde eine systematische Literaturrecherche nach (inter-)nationalen Leitlinien und systematischen Übersichtsarbeiten zur Gonarthrose und Knieendoprothetik durchgeführt, um klinisch relevante Fragestellungen zu Diagnostik, Prädiktoren für das Outcome, Risikofaktoren und Kontraindikatoren zu beantworten.Eine Knieendoprothese soll nur bei radiologisch nachgewiesener fortgeschrittener Gonarthrose (Kellgren-Lawrence-Grad 3 oder 4), nach vorangegangener konservativer Therapie über mindestens 3 Monate sowie bei hohem subjektivem Leidensdruck hinsichtlich der kniebezogenen Beschwerden und nach Ausschluss möglicher Kontraindikationen (Infektionen, Begleiterkrankungen, BMI ≥ 40 kg/m2) erfolgen. Modifizierbare Risikofaktoren (wie Rauchen, Diabetes mellitus, Anämie) sollen zuvor adressiert und ggf. optimiert werden. Die Ziele der Patient*innen sollen erfragt und deren Eintrittswahrscheinlichkeit gemeinsam besprochen werden. Schließlich ist die Entscheidung zur Knieendoprothese von Patient*in und Operateur*in gemeinsam zu treffen, wenn der zu erwartende Nutzen die möglichen Risiken überwiegt.Das Update der S2k-Leitlinie wurde um die unikondyläre Knieendoprothese erweitert, die präoperative Optimierung modifizierbarer Risikofaktoren ergänzt sowie Konkretisierungen der Hauptindikationskriterien vorgenommen.

ZUSAMMENFASSUNGZwischen 1/15 000 und 1/50 000 Passagiere haben während eines Fluges akute medizinische Probleme, wobei Herzstillstände, die eine kardiopulmonale Wiederbelebung (CPR) erfordern, 0,3 % der medizinischen Notfälle ausmachen. Hypoxie in der Flugzeugkabine könnte die Sauerstoffversorgung und die körperliche Leistungsfähigkeit des Helfenden beeinträchtigen, deshalb wurde eine randomisierte, kontrollierte Doppelblindstudie durchgeführt, um die Hypothese zu testen, dass Hypoxie die Effektivität der CPR verringert. 24 medizinische Fachkräfte wurden in 2 verschiedene Studienarme randomisiert, die jeweils 2 Bedingungen testeten. Mixed ANOVAs mit Post-hoc-False-Discovery-Rate mit paarweisen Vergleichen zeigten, dass eine längere Hypoxieexposition, die den Bedingungen eines Langzeitflugs entspricht, die Qualität der Thoraxkompressionen beeinträchtigen kann. Zusätzlicher Sauerstoff für das medizinische Personal ist eine wirksame Gegenmaßnahme.

Objective This study aimed to test the hypothesis that being pregnant and delivering during the coronavirus disease 2019 (COVID-19) pandemic was associated with changes in gestational weight gain (GWG) or frequency of small- (SGA) or large-for-gestational-age (LGA) neonates.
Study Design Secondary analysis of a multicenter observational cohort comparing pregnant people who delivered during the COVID-19 pandemic (June–December 2020) to people who delivered prior to the pandemic (March–December 2019). Those with multiple gestations, fetuses with major congenital anomalies, implausible GWG values, unavailable body mass index (BMI), or who were severe acute respiratory syndrome coronavirus-2-positive were excluded. The primary outcome was frequency of optimal recommended GWG based on prepregnancy BMI. Neonatal outcomes included birth weight, ponderal index, and frequency of SGA, LGA, and small head circumference for live births. Multivariable regression analysis was used to assess associations between exposure to the pandemic and outcomes.
Results A total of 10,717 pregnant people were included in our analysis. A total of 4,225 pregnant people were exposed to the pandemic and 6,492 pregnant people delivered prior to the COVID-19 pandemic. Pregnant people exposed to the pandemic were older and more likely to have gestational diabetes. The frequency of appropriate GWG was 28.0% during the pandemic and 27.6% before the pandemic (adjusted odds ratio [aOR]: 1.02, 95% confidence interval [CI]: 0.93–1.11). Excessive GWG was more likely (54.9 vs. 53.1%; aOR: 1.08, 95% CI: 1.001–1.17), and inadequate GWG was less likely during the pandemic (17.0 vs. 19.3%; aOR: 0.86, 95% CI: 0.77–0.95). The frequency of SGA was 5.4% during the pandemic and 6.1% before the pandemic (aOR: 0.90, 95% CI: 0.76–1.06), and the frequency of LGA was 16.0% during the pandemic versus 15.0% before the pandemic (aOR: 1.06, 95% CI: 0.95–1.18). Other neonatal outcomes including birth weight percentile (62.1 [35.8–83.2] vs. 60.2 [34.4–82.2]; adjusted mean difference (aMD) = 1.50, 95% CI: −0.28 to 3.29), ponderal index (2.6 g/cm3 [2.4–2.8] in both groups; aMD = 0.01, 95% CI: 0.00–0.02), and small head circumference for livebirths (<10th percentile [8.2 vs. 8.1%; aOR: 1.03, 95% CI: 0.89–1.19], <3rd percentile [3.5 vs. 3.1%; aOR: 1.16, 95% CI: 0.93–1.44]) were similar between groups as well.
Conclusion Being pregnant and delivering during the COVID-19 pandemic was associated with a higher likelihood of excessive GWG and a lower likelihood of inadequate GWG.

AbstractWeightlifting has become an increasingly popular form of exercise that has been
shown to have many health benefits but can be dangerous if performed improperly.
The objective of this study was to describe the epidemiology of lower body
weightlifting injuries in the United States. The National Electronic Injury
Surveillance System database was queried from January 1, 2012, to December 31,
2021, for lower body injuries related to using weightlifting equipment.
Demographics, diagnosis, disposition, and mechanism of injury (MOI) were
analyzed. There were 7,773 lower extremity weightlifting injuries identified
from 2012–2021, giving a national estimate of 311,842 injuries. The most common
MOI was dropped weight (n=1785, 22.96%). Deadlifts were the most cited exercise
that led to lower extremity injury (n=503, 6.47%). Males were more likely than
females to be injured (76% males vs. 24% females; p<0.001), especially by
compound movements with free weights including squats (79.63% males vs. 19.96%
females, p<0.03) and deadlifts (83.89% males vs. 16.10% females, p<0.001).
Nearly all injuries were treated as outpatient but those admitted to the
hospital were significantly older than those treated as outpatients (38.0 years
vs. 31.2 years, p<0.05). Weightlifting carries a high risk of injury due to
the intensity and technique required for the different movements involved.

AbstractWe report facile and versatile procedures for the synthesis of exo- and endo-isomeric spirocyclic hybrids of pharmacophoric (1R,5S)-8-azabicyclo[3.2.1]octane (nortropane) and 1,3-oxazinan-2-one fragments. Our approach consists of the hydrocyanation of endo- and exo-isomeric N-Cbz-protected nortropane-3-spiroepoxides, the reduction of hydroxy nitriles into amino alcohols, the synthesis of N-alkylated amino alcohols via reductive amination, the spirocyclization of the amino alcohols, N-alkylation of the unsubstituted 1,3-oxazinan-2-one fragment in the spiro compounds, and removal of the Cbz protecting groups.

Published: May 2024

AbstractA simple and efficient approach for the synthesis of privileged oxime esters by employing donor-acceptor cyclopropane diesters (DACs) as one of the potential precursors is reported. The strategy involves Lewis acid catalyzed ring-opening of DACs, resulting in an open-chain intermediate followed by the base-mediated construction of the corresponding oxime esters in a one-pot reaction. Moreover, the process also features the synthesis of diethyl 4-(4-methoxyphenyl)azete-2,2(3H)-dicarboxylate.
