Authors: Wang Yunpeng , Wang Shize , Xu Qiang , Feng Xiujuan , Li Yanhui , Sun Ruiqi , Zhang Wei , Yamamoto Yoshinori , Bao Ming 
Published: December 2024

AbstractHigh entropy alloys (HEAs) are promising heterocatalysts because of their unique physicochemical properties, but research on HEA‐catalyzed tandem reactions is lacking. Moreover, limited research on HEAs for molecular transformation has hindered their development. Herein, an unsupported nanoporous HEA Al‐Pt‐Pd‐Ru (HEANPore) prepared using a top‐down dealloying method is reported. The Lewis acidity and electron redistribution of the noble metals Pt, Pd, and Ru are identified to be intrinsic of high activity and selectivity of HEANPore in the one‐pot reductive amination of nitroarenes. The competitive adsorption of the reactant and corresponding reaction mechanism are investigated using DFT. This study demonstrates the exceptional performance of the HEANPore in tandem reactions, presenting new possibilities for the application of HEAs in the field of catalysis.

Angular distributions of Drell-Yan leptons in the TMD factorization approach
Authors: Piloñeta Sara , Vladimirov Alexey 
Published: December 2024

Abstract
We present a comprehensive study of the angular structure functions for Drell-Yan leptons in Z/γ-boson production within the framework of the transverse momentum dependent (TMD) factorization theorem, including kinematic power corrections (KPCs). We find good agreement with the data in the applicability region of the TMD factorization theorem. The inclusion of KPCs allows us to describe all angular coefficients in a frame-independent manner using only the leading-twist TMD distributions: the unpolarized and the Boer-Mulders functions. The value of the Boer-Mulders function is determined using the ATLAS measurement of the A2 angular coefficient. The analysis is performed at N4LL perturbative order. Additionally, we discuss the technical implementation and impact of KPCs on the phenomenology of TMD distributions.

Outcomes of Intranodal and Modified Intranodal Lymphangiography for Treatment of Traumatic Chylous Leaks in the Thorax and Neck
Authors: Parikh Rupal , Seyferth Elisabeth R. , Palat Sanjay , Itkin Maxim , Nadolski Gregory J. 
Published: December 2024

Abstract
Purpose
To report outcomes, procedure and fluoroscopy times, and adverse event rates after intranodal lymphangiography (IL) and modified IL (mIL) for treatment of traumatic chylous leaks in the thorax and neck.

Methods
Under an IRB-approved protocol, retrospective review of a quality assurance database identified all lymphangiograms for post-surgical refractory chylous leaks in the thorax and neck at a tertiary center from 2002–2022. Records were reviewed for technical and clinical outcomes, procedure and fluoroscopy times, and adverse events. Pedal lymphangiograms were excluded. Patients were categorized into IL (pre-2016) and mIL (post-2016) cohorts. mIL incorporated pneumatic calf compression throughout the procedure. Technical success was defined as successful thoracic duct cannulation. Clinical success was defined as leak resolution and eventual chest or other drain removal within 2 weeks post-procedure. A two-tailed Fischer’s exact test was used to compare categorical outcomes. A two-tailed t test was used to compare means.

Results
Two hundred and thirty-nine patients underwent 263 thoracic duct embolizations of traumatic chylous leaks in the thorax/neck. Intranodal lymphangiography was used in 167 cases in 150 patients. Overall clinical success was 94.6% [n = 142/150]. Technical success was higher in mIL (94.2% [81/86]) than IL (76.5% [62/81]) (p = 0.002). Clinical success per patient and procedure were similar between cohorts (92.3% [72/78] mIL versus 97.2% [70/72] IL, p = 0.27, and 83.7% [72/86] mIL versus 85.1% [69/81] IL, p = 0.83, respectively). Mean procedure time in mIL (83.4 ± 31.9 min) was shorter than in IL (119.2 ± 45.9 min) (p < 0.0001). Mean fluoroscopy time in mIL (33.8 ± 17.3 min) was shorter than in IL (41.7 ± 23.2 min) (p = 0.02). Adverse event rate was not significantly different between groups.

Conclusion
Overall, thoracic duct embolization for traumatic chylothorax has high clinical success, approaching 95%. While clinical success of mIL was similar to IL, technical success and mean procedure and fluoroscopic times were significantly improved. Findings suggest modified intranodal lymphangiography should be utilized to treat traumatic chylothorax.

Published: December 2024

Abstract
Aim
Diagnostic imaging is an integral part of identifying spondyloarthropathies (SpA), yet the interpretation of these images can be challenging. This review evaluated the use of deep learning models to enhance the diagnostic accuracy of SpA imaging.

Methods
Following PRISMA guidelines, we systematically searched major databases up to February 2024, focusing on studies that applied deep learning to SpA imaging. Performance metrics, model types, and diagnostic tasks were extracted and analyzed. Study quality was assessed using QUADAS-2.

Results
We analyzed 21 studies employing deep learning in SpA imaging diagnosis across MRI, CT, and X-ray modalities. These models, particularly advanced CNNs and U-Nets, demonstrated high accuracy in diagnosing SpA, differentiating arthritis forms, and assessing disease progression. Performance metrics frequently surpassed traditional methods, with some models achieving AUCs up to 0.98 and matching expert radiologist performance.

Conclusion
This systematic review underscores the effectiveness of deep learning in SpA imaging diagnostics across MRI, CT, and X-ray modalities. The studies reviewed demonstrated high diagnostic accuracy. However, the presence of small sample sizes in some studies highlights the need for more extensive datasets and further prospective and external validation to enhance the generalizability of these AI models.

Key Points
QuestionHow can deep learning models improve diagnostic accuracy in imaging for spondyloarthropathies (SpA), addressing challenges in early detection and differentiation from other forms of arthritis?
FindingsDeep learning models, especially CNNs and U-Nets, showed high accuracy in SpA imaging across MRI, CT, and X-ray, often matching or surpassing expert radiologists.
Clinical relevanceDeep learning models can enhance diagnostic precision in SpA imaging, potentially reducing diagnostic delays and improving treatment decisions, but further validation on larger datasets is required for clinical integration.

Authors: Bräutigam Matilda , Dellenmark-Blom Michaela , Abrahamsson Kate , Gatzinsky Cathrine , Gatzinsky Vladimir 
Published: December 2024

Abstract
Purpose
The aim was to determine gastrointestinal (GI)-related QoL in children born with gastroschisis (GS).

Methods
Totally, 58/83 families of children (aged 2–18 years) operated for GS at a tertiary pediatric surgical center accepted participation. Children aged 5–18 and one parent (child aged 2–18) completed the Swedish version of the PedsQL™ gastrointestinal symptoms module, evaluating GI-related QoL with 14 different GI-specific scales, norm values for Hirschsprung’s disease (HD), esophageal atresia (EA), and functional constipation (FC) that were used for comparison.

Results
Children with GS had significantly lower parent-reported scores on “Gas and bloating” compared with children with EA (77.0 vs 85.5, p = 0.039). In the child report and in the parent report, scores on several GI scales were like those of children with EA. Parents of children with GS had higher scores for 8/14 scales compared to HD and higher scores for 12/14 scales compared to FC. Clinical GS-specific factors for worse GI-QoL were identified, including “Days in ventilator” and “Days with Silo and Patch”.

Conclusions
GS has an impact on GI-related QoL, comparable to that in EA, but not to HD or FC. The GS-specific factors of worse QoL show the importance regarding a GS follow-up program including considering clinical factors.

Zusammenfassung
Zur Bewertung der Versorgungsqualität, insbesondere bei neuen Versorgungsformen (nVF), werden die zu erbringenden Gesundheitsleistungen vorab definiert und dokumentiert. Das vorgestellte Explanatory-Sequential-Mixed-Methods-Design kombiniert quantitative und qualitative Datenerhebungen, und seine Analyse ermöglicht ein vertieftes Verständnis einer nVF. Am Beispiel des Projekts POET-Pain, das die Wirkung eines perioperativen „Transitional Pain Service“ (TPS) untersucht, wird die methodische Anwendung des Explanatory-Sequential-Mixed-Methods-Designs demonstriert, um die Struktur- und Prozessevaluation der nVF (hier TPS) vorzustellen und deren Einfluss auf die Versorgungsqualität zu verstehen. Das vorgestellte Mixed-methods-Design ermöglicht es, die Ergebnisse der quantitativen Phase anhand qualitativer Daten vertiefend zu interpretieren und zu erweitern, was zu einem umfänglichen Verständnis des Gegenstands (zweite Säule der Versorgungsforschung) führt.
Ermittlung von Resonanzfaktoren zur Oberschwingungsbewertung nach VDE-AR-N 4110 basierend auf Netzimpedanzmessungen
Authors: Schräder Johannes , Meyer Marc Florian , Möbius Patrick , Schulz Detlef , Jordan Michael 
Published: December 2024

ZusammenfassungBisher werden Resonanzfaktoren auf der Grundlage verschiedener Annahmen ermittelt. Das kann zu einer Überschätzung dieser Faktoren führen und somit die elektrische Charakteristik des Netzanschlusspunkts fehlerhaft abbilden. Dadurch kann es dazu kommen, dass Erzeugungsanlagen die Netzeinspeisung versagt wird, obwohl hierfür bei genauerer Betrachtung keine sachliche Grundlage vorliegt. In diesem Beitrag wird gezeigt, wie man durch die Messung der Netzimpedanz am Verknüpfungspunkt zu praktisch relevanten Bewertungen kommen kann. Hierfür wird die Oberschwingungsbewertung im Netzanschlussprozess erläutert und eine angepasste Bewertung anhand eines realen Fallbeispiels präsentiert. Darüber hinaus werden die Resonanzfaktoren weiterer Netzanschlusspunkte auf der Basis realer Messungen ermittelt und miteinander verglichen. Anhand der Ergebnisse kann festgestellt werden, dass messwertbasierte Resonanzfaktoren in der Regel höhere Oberschwingungsstromgrenzwerte erlauben.
Particle swarm optimization with local search for height-map surface reconstruction from point clouds in reverse engineering
Authors: Gálvez Akemi , Fister Iztok , Deb Suash , Fister Iztok , Iglesias Andrés 
Published: December 2024

AbstractSurface reconstruction is a classical process in industrial engineering and manufacturing, particularly in reverse engineering, where the goal is to obtain a digital model from a physical object. For that purpose, the real object is typically scanned or digitized and the resulting point cloud is then fitted to mathematical surfaces through numerical optimization. The choice of the approximating functions is crucial for the accuracy of the process. Real-world objects such as manufactured workpieces often require complex nonlinear approximating functions, which are not well suited for standard numerical methods. In a previous paper presented at the ISMSI 2023 conference, we addressed this issue by using manually selected approximation functions via optimization through the cuckoo search algorithm with Lévy flights. Building upon that work, this paper presents an enhanced and extended method for surface reconstruction by using height-map surfaces obtained through a combination of exponential, polynomial and logarithmic functions. A feasible approach for this goal is to consider continuous bivariate distribution functions, which ensures consistent models along with good mathematical properties for the output shapes, such as smoothness and integrability. However, this approach leads to a difficult multivariate, constrained, multimodal continuous nonlinear optimization problem. To tackle this issue, we apply particle swarm optimization, a popular swarm intelligence technique for continuous optimization. The method is hybridized with a local search procedure for further improvement of the solutions and applied to a benchmark of 15 illustrative examples of point clouds fitted to different surface models. The performance of the method is analyzed through several computational experiments. The numerical and graphical results show that the method is able to recover the shape of the point clouds accurately and automatically. Furthermore, our approach outperforms other alternative methods significantly in terms of the numerical errors. We conclude that our method can be successfully applied to the reconstruction of manufactured workpieces in real industrial settings.
Impfverhalten in Bezug auf COVID-19 („coronavirus disease 2019“)
Authors: Helbing Alexander 
Published: December 2024

Zusammenfassung
Ziel der Studie
Die Wirksamkeit von Impfkampagnen ist nur gewährleistet, wenn sich eine ausreichende Anzahl von Personen impfen lässt. In Bezug auf die COVID-19-Pandemie („coronavirus disease 2019“) gibt es bereits zahlreiche frühe Studien zur Impfbereitschaft. Es mangelt aber an Studien zum tatsächlichen Impfverhalten. Die vorliegende Studie zielt darauf ab, retrospektiv das Impfverhalten zu messen und mit Hilfe verschiedener, z. T. wenig untersuchten, Einflussfaktoren zu erklären.

Methodik
Zwischen März bis April 2023 wurde im Rahmen eines anderen Projektes eine Querschnittstudie mittels Online-Fragebogen an 2750 Personen in Deutschland durchgeführt. Die Daten wurden schließlich mit Hilfe einer multiplen logistischen Regression ausgewertet.

Ergebnisse
Es haben 88,5 % der Befragten angegeben, sich mindestens einmal gegen COVID-19 geimpft gelassen zu haben. Die Ergebnisse der multiplen logistischen Regression deuten darauf hin, dass Misstrauen gegenüber der Berichterstattung des Robert Koch-Instituts das Impfverhalten negativ beeinflusst, während Misstrauen gegenüber sozialen Medien dieses erhöht. Personen, die potenziell die AfD (Alternative für Deutschland) wählen würden, weisen die geringste Impfquote unter allen Wahlpräferenzen auf. Die Zugehörigkeit zu einer COVID-19-Risikogruppe ist positiv mit dem Impfverhalten assoziiert. Eine geringe subjektive Risikoeinschätzung in Bezug auf COVID-19 weist eine negative Assoziation auf. Schließlich zeigt sich, dass die Anzahl der geimpften Personen im sozialen Netzwerk, das individuelle Impfverhalten positiv beeinflusst.

Schlussfolgerung
Die Ergebnisse unterstreichen die Bedeutung von Vertrauen in Informationsquellen und die Risikoeinschätzung bezüglich COVID-19. Neue Erkenntnisse zu sozialen Netzwerken und der AfD-Affinität legen den Grundstein für weitere Untersuchungen.
Seismic hazard assessment in the Podhale region, Poland—zone and smoothed seismicity approach
Authors: Plesiewicz Beata , Wiszniowski Jan , Karkowska Kamila , Kijko Andrzej 
Published: December 2024

AbstractPoland is characterised by weak natural seismicity. However, the last analysis of the natural seismic hazard in the country was carried out 24 years ago. Therefore, a significant fraction of the recorded seismicity is not included in the hazard estimates currently used, either because recent observations are not taken into account or because of improved seismic network capabilities. Furthermore, Podhale, in the Tatra Mountains, is the only region with recorded permanent natural seismicity. This study aims to create new seismic hazard maps of the Podhale region from a newly compiled database containing information on historical events and two complete instrumental catalogues (regional and local), each at a different level of completeness. The local catalogue was recorded over the last few years. Two seismic hazard assessment techniques were applied, namely the conventional (zone-based) (Cornell in Bull Seismol Soc Am 58(5): 1583–1606, 1968) and the smoothed seismicity model, based on the spatial distribution of seismicity. The earthquake recurrence parameters were estimated using the methodology developed by Kijko et al. (Bull Seismol Soc Am 106: 1210–1222, 2016). The new seismic hazard model incorporates several improvements, such as a comprehensive logic tree and a new set of ground motion models. The new maps provide a more detailed assessment of the seismic hazards of the investigated area. Moreover, they predict higher PGA than previous seismic hazard maps covering Podhale, like global European Seismic Hazard Maps 2013 and 2020.
Die „Hangkriterien“ der Neufassung von § 64 StGB – Implikationen für das Therapieergebnis?
Authors: Stübner Susanne , Schwarz Michael 
Published: December 2024

ZusammenfassungDie Novellierung von § 64 des Strafgesetzbuches (StGB) ist am 01.10.2023 in Kraft getreten. Es erfolgte u. a. eine Spezifizierung des „Hangs“: Gefordert sind nun das Vorliegen einer Substanzkonsumstörung und in dessen Folge eine dauernde und schwerwiegende Beeinträchtigung von Lebensgestaltung, Gesundheit, Arbeitsfähigkeit oder Leistungsfähigkeit („Hangkriterien“). In einer vorangegangenen Arbeit der Verfasser (Schwarz und Stübner 2023) wurde eine retrospektive Aktenanalyse durchgeführt bei n = 70 männlichen Patienten, deren Unterbringung gemäß § 64 StGB in der Klinik für Forensische Psychiatrie am Bezirksklinikum Ansbach (Bayern) zwischen dem 01.07.2021 und dem 30.06.2022 beendet worden war (Querschnittvollerfassung). In der hier vorliegenden explorativen Sekundäranalyse dieser Daten sollte nun ein etwaiger Zusammenhang zwischen dem Therapieergebnis (bedingte Entlassung aus der Maßregel oder vorzeitige Erledigung) und der im jeweiligen Fall vorliegenden Art und Anzahl der Hangkriterien fokussiert werden. Es zeigte sich, dass bei Patienten mit einem regulären Therapieabschluss im Durchschnitt höhere Anzahlen von Hangkriterien vorgelegen hatten, insbesondere Beeinträchtigungen der Arbeitsfähigkeit. In dieser Gruppe waren allerdings weniger schwere psychiatrische Komorbiditäten zu verzeichnen. Zwischen den einzelnen Hangkriterien wurden teils hochsignifikante Zusammenhänge ermittelt. Insgesamt deutet sich an, dass die neue Konturierung des Hangbegriffs zu einer gezielteren Zuweisung von Patienten, die von den spezifischen Therapieangeboten in einer Entziehungsanstalt profitieren, führen könnte. Zudem scheinen sich die rechtswissenschaftlich intendierten Verbesserungen mit erfahrungswissenschaftlichen Methoden abbilden zu lassen.
