Published: September 2024

Abstract
This study introduces a high-order perturbation methodology to categorize two primary solution types within duality-invariant nonlinear electrodynamic theories, adhering to the differential self-duality criterion. The first solution type aligns with irrelevant stress tensor flows, resembling $$ T\overline{T} $$

Numerical conformal bootstrap with analytic functionals and outer approximation
Authors: Ghosh Kausik , Zheng Zechuan 
Published: September 2024

Abstract
This paper explores the numerical conformal bootstrap in general spacetime dimensions through the lens of a distinct category of analytic functionals, previously employed in two-dimensional studies. We extend the application of these functionals to a more comprehensive backdrop, demonstrating their adaptability and efficacy in general spacetime dimensions above two. The bootstrap is implemented using the outer approximation methodology, with computations conducted in double precision. The crux of our study lies in comparing the performance of this category of analytic functionals with conventional derivatives at crossing symmetric points. It is worth highlighting that in our study, we identified some novel kinks in the scalar channel during the maximization of the gap in two-dimensional conformal field theory. Our numerical analysis indicates that these analytic functionals offer a superior performance, thereby revealing a potential alternative paradigm in the application of conformal bootstrap.
Bosonic and fermionic coherence of N-partite states in the background of a dilaton black hole
Authors: Li Wen-Mei , Wu Shu-Min 
Published: September 2024

Abstract
We study the N-partite coherences of GHZ and W states for free bosonic and fermionic fields when any n observers hover near the event horizon of a Garfinkle-Horowitz-Strominger (GHS) dilaton black hole. We derive the more general analytical expressions for N-partite coherence, encompassing both physically accessible and inaccessible coherences in the context of the dilaton black hole. It has been found that the coherence of the bosonic field is greater than that of the fermionic field, while the entanglement of the fermionic field is greater than that of the bosonic field in dilaton spacetime. Additionally, the coherence of the W state is greater than that of the GHZ state, whereas the entanglement of the GHZ state is greater than that of the W state in curved spacetime. These results suggest that we should utilize suitable quantum resources and different types of particles for relativistic quantum information tasks.

orbifold building blocks are admissible in heterotic string compactifications. We investigate the flavor properties of all of these building blocks. In each case, we identify the traditional and modular flavor symmetries, and determine the corresponding representations and (fractional) modular weights of the available massless matter states. The resulting finite flavor symmetries include Abelian and non-Abelian traditional symmetries, discrete R symmetries, as well as the double-covered finite modular groups (S3 × S3) ⋊ ℤ4, T′, 2D3 and S3 × T′. Our findings provide restrictions for bottom-up model building with consistent ultraviolet embeddings.
Surfaceology for colored Yukawa theory
Authors: De Shounak , Pokraka Andrzej , Skowronek Marcos , Spradlin Marcus , Volovich Anastasia 
Published: September 2024

Abstract
Arkani-Hamed and collaborators have recently shown that scattering amplitudes for colored theories can be expressed as integrals over combinatorial objects simply constructed from surfaces decorated by kinematic data. In this paper we extend the curve integral formalism to theories with colored fermionic matter and present a compact formula for the all-loop, all-genus, all-multiplicity amplitude integrand of a colored Yukawa theory. The curve integral formalism makes certain properties of the amplitudes manifest and repackages non-trivial numerators into a single combinatorial object. We also present an efficient formula for L-loop integrated amplitudes in terms of a sum over 2L combinatorial determinants.
Extremal fixed points and Diophantine equations
Authors: Herzog Christopher P. , Jepsen Christian B. , Osborn Hugh , Oz Yaron 
Published: September 2024

Abstract
The coupling constants of fixed points in the ϵ expansion at one loop are known to satisfy a quadratic bound due to Rychkov and Stergiou. We refer to fixed points that saturate this bound as extremal fixed points. The theories which contain such fixed points are those which undergo a saddle-node bifurcation, entailing the presence of a marginal operator. Among bifundamental theories, a few examples of infinite families of such theories are known. A necessary condition for extremality is that the sizes of the factors of the symmetry group of a given theory satisfy a specific Diophantine equation, given in terms of what we call the extremality polynomial. In this work we study such Diophantine equations and employ a combination of rigorous and probabilistic estimates to argue that these infinite families constitute rare exceptions. The Pell equation, Falting’s theorem, Siegel’s theorem, and elliptic curves figure prominently in our analysis. In the cases we study here, more generic classes of multi-fundamental theories saturate the Rychkov-Stergiou bound only in sporadic cases or in limits where they degenerate into simpler known examples.
Asymptotic Expansions for the Radii of Starlikeness of Normalized q-Bessel Functions
Authors: Baricz Árpád , Kumar Pranav , Singh Sanjeev 
Published: September 2024

AbstractIn this paper we study the asymptotic behavior of the radii of starlikeness of the normalized Jackson’s second and third q-Bessel functions, focusing on their large orders. To achieve this, we use the Rayleigh sums of positive zeros of both q-Bessel functions, and determine the coefficients of the asymptotic expansions. We derive complete asymptotic expansions for these radii of starlikeness and provide recurrence relations for the coefficients of these expansions. The proofs rely on the notion of Rayleigh sums of positive zeros of q-Bessel functions, Kvitsinsky’s results on spectral zeta functions for q-Bessel functions and asymptotic inversion. Moreover, we derive bounds for the radius of starlikeness of q-Bessel functions by using potential polynomials.
Kollaborationen bei kinderanästhesiologischen Publikationen im D-A-CH-Raum
Authors: Dejaco Alexander , Nemeth M. , Sablewski A. , Rosenberger J. , Miller C. 
Published: September 2024

Zusammenfassung
Hintergrund
Kollaborationen sind ein wesentlicher Baustein wissenschaftlichen Arbeitens und speziell für Bereiche wie die Kinderanästhesiologie besonders bedeutsam, wo ein geringes Evidenzlevel besteht. Eine kürzlich durchgeführte szientometrische Analyse ergab eine geografische Diversifizierung der Publikationsaktivität in der Kinderanästhesie innerhalb der letzten 2 Jahrzehnte, begleitet von einem Anstieg internationaler Kooperationen.

Ziele
Vor dem Hintergrund der Hypothese eines ähnlichen Wachstums der Aktivität und Dynamik von Veröffentlichungen in der Kinderanästhesie bestand das Ziel dieser szientometrischen Studie darin, die Publikationsaktivität und Kooperationsgewohnheiten in der Kinderanästhesieforschung in Deutschland, Österreich und der Schweiz (D-A-CH) zu analysieren.

Methode
Diese Sekundäranalyse schloss alle kinderanästhesiologischen Publikationen mit Zugehörigkeit aus dem D‑A-CH-Raum zwischen 2001 und 2020 aus PubMed und Web of Science ein. Publikationen wurden anhand der Korrespondenzadresse zugeordnet. Primärer Endpunkt war die Publikationsaktivität und -dynamik, dargestellt anhand der Anzahl der Veröffentlichungen und den jeweiligen Wachstumsraten. Sekundäre Endpunkte waren die Anteile an Kollaborationen auf staatlicher und institutioneller Ebene.

Ergebnisse
Insgesamt wurden 3406 kinderanästhesiologische Publikationen mit Beteiligung aus dem D‑A-CH-Raum identifiziert, davon 2807 (82,4 %) mit Korrespondenzadresse. Die durchschnittliche jährliche Wachstumsrate an Publikationen mit Korrespondenzadresse lag für den D‑A-CH-Raum bei + 2,9 % und bei Kollaborationen + 7,7 %. Kollaborationen fanden überwiegend zwischen Institutionen innerhalb des D‑A-CH-Raums statt, aber Schweizer Institutionen hatten einen höheren Anteil an internationalen Kollaborationen.

Diskussion
Die Aktivität bei kinderanästhesiologischen Publikationen aus dem D‑A-CH-Raum nahm in den letzten beiden Dekaden stetig zu, wobei Kollaborationen eine überproportionale Zunahme verzeichneten. Es bleibt zu wünschen, dass sich mit der wachsenden Bedeutung von Kollaborationen auch die Evidenzlage in der Kinderanästhesie weiter verbessert.
Risikofaktoren und Präventionsstrategien periprothetischer Femurfrakturen in der Hüftendoprothetik
Authors: Alimy Assil-Ramin , Soltys Pauline Julie , Hubert Jan , Ries Christian , Beil Frank Timo , Rolvien Tim 
Published: September 2024

Zusammenfassung
Hintergrund
Periprothetische Frakturen stellen eine bedeutende Komplikation der Endoprothetik dar, insbesondere nach Implantation einer Hüfttotalendoprothese (Hüft-TEP). Durch den demographischen Wandel wird prognostiziert, dass mit der steigenden Anzahl von Hüft-TEP-Implantationen auch eine Zunahme von periprothetischen Femurfrakturen (PPF) in den nächsten Jahrzehnten zu erwarten ist. Trotz der daraus abzuleitenden hohen klinischen Relevanz existiert bisher keine umfassende Übersicht zu Risikofaktoren und möglichen präventiven Ansätzen von PPF.

Ziel der Arbeit
Ziel dieser Übersichtsarbeit ist es, die aktuellen Erkenntnisse und Daten aus verschiedenen Studien darzustellen und daraus evidenzbasierte Empfehlungen für die klinische Praxis abzuleiten.

Material und Methoden
Narratives Review.

Ergebnisse
Das Auftreten von PPF kann durch verschiedene Risikofaktoren wie höheres Lebensalter, weibliches Geschlecht und rheumatische Erkrankungen begünstigt werden. Bei Vorliegen dieser Risikofaktoren sollte vor der Primäroperation die Indikation zur Untersuchung der Knochengesundheit, inklusive DXA-Messung, großzügig gestellt werden.

Schlussfolgerungen
Eine individualisierte Herangehensweise ist bei der Planung und Implantation einer Hüft-TEP essenziell, um das Risiko für PPF zu minimieren. Bei nachgewiesener Osteoporose oder einem Alter von ≥ 70 Jahren bei Frauen bzw. ≥ 75 Jahren bei Männern sollte eine zementierte Schaftverankerung gewählt werden, da zementfreie Schäfte in diesem Kontext mit einem erhöhten Risiko für PPF verbunden sind. Insgesamt sollte das klinische Risikoprofil bei der präoperativen Planung und der postoperativen Nachsorge berücksichtigt werden, um diese Komplikation zu reduzieren und die Patientenversorgung zu verbessern.
An agent-based approach to the limits of economic planning
Authors: Martinelli Emanuele 
Published: September 2024

AbstractMises’ and Hayek’s arguments against central economic planning have long been taken as definitive proof that a centrally planned economy managed by the government would be impossible. Today, however, the exponential rise in the capacities of AI has opened up the possibility that supercomputers could have what it takes to plan the national economy. The ‘economic calculation debate’ has thus reignited. Arguably, this is because neither Mises nor Hayek have given a clear and conclusive argument why central planning of the economy is impossible in principle. The paper frames the problem of economic planning as an agent–environment interaction, offering a taxonomy of the different sets of agents at play a) in a market economy and b) in a centrally planned economy equipped with the most sophisticated AI technology. The argument is that public institutions as planning bodies cannot replace the market order, no matter the AI technology behind them, for the elimination of the market entails the elimination of crucial kinds of agents that cannot be recreated or emulated through AI or careful social planning: the proactive action of entrepreneurs driving market allocation.
Capital flow freezes
Authors: Peiris M. Udara , Sokolova Anna , Tsomocos Dimitrios P. 
Published: September 2024

AbstractThe period following the 2008 financial crisis focused attention on “twin-crises,” where banking crises precipitate sovereign crises due to increased bank support. We show that when private sector debt is renegotiated centrally, and bargaining power is low, it results in suboptimally low levels of debt and default rates (haircuts). If, instead, the bargaining power is sufficiently high, the supply of debt exceeds its demand and capital inflows “freeze”. These inefficiencies arise because the decentralized borrowers fail to consider how their bond supply impacts debt renegotiation outcomes, affecting both bond prices and the asset span. These issues can be addressed through macroprudential policies in the form of taxing capital inflows.
Fermented Dairy Products, Musculoskeletal and Mental Health in Older Adults: is There Evidence to Support Benefits that go Beyond Those of Non-Fermented Dairy Products?
Authors: Papageorgiou M. , Lyrakou M. , Kyriacou A. , Biver E. , Yannakoulia M. 
Published: September 2024

AbstractFermented dairy products have recently gained popularity due to their purported health benefits, nevertheless, their role in ageing remains uncertain. This narrative review aims to evaluate evidence from observational (prospective) and interventional studies on the potential benefits of fermented dairy product consumption for musculoskeletal and mental health in older adults. Additionally, it seeks to determine whether any observed benefits surpass those of non-fermented dairy products and to identify directions for future research. Prospective studies support either favourable or neutral associations of fermented dairy products with outcomes of musculoskeletal health or neutral associations with mental health outcomes, whilst it remains unclear if the benefits observed with fermented dairy products go beyond those of the non-fermented dairy foods. Few interventional studies suggest overall favourable effects of yogurt and cheese on musculoskeletal health in older adults but given their small number (N = 6) and heterogeneity, they do not allow a clear assessment or definitive recommendations for fermented dairy intake. Interventional studies reporting mental health outcomes are largely lacking for this age group (N = 1). Given the very limited evidence for the effectiveness of fermented dairy products, future well-designed prospective and randomized controlled trials are needed to better understand their benefits (especially compared to those of non-fermented dairy foods), their characteristics and the quantities required to offer protection against musculoskeletal and/or mental health ageing.

Abstract
The introduction of dual-energy X-ray absorptiometry (DXA) technology in the 1980s revolutionized the diagnosis, management and monitoring of osteoporosis, providing a clinical tool which is now available worldwide. However, DXA measurements are influenced by many technical factors, including the quality control procedures for the instrument, positioning of the patient, and approach to analysis. Reporting of DXA results may be confounded by factors such as selection of reference ranges for T-scores and Z-scores, as well as inadequate knowledge of current standards for interpretation. These points are addressed at length in many international guidelines but are not always easily assimilated by practising clinicians and technicians. Our aim in this report is to identify key elements pertaining to the use of DXA in clinical practice, considering both technical and clinical aspects. Here, we discuss technical aspects of DXA procedures, approaches to interpretation and integration into clinical practice, and the use of non-bone mineral density measurements, such as a vertebral fracture assessment, in clinical risk assessment.
Collagen-V and K-α-1 Tubulin Antibodies as Potential Markers of Unsuspected GERD-Related Lung Damage: Insights from a Cross-Sectional Analysis

Published: September 2024

Abstract
Purpose
Our group has proposed that aspiration of gastric contents leads to exposure of normally sequestered lung self-antigens (SAgs), specifically collagen-V (Col-V) and K-α-1-tubulin (Kα1T), which elicits an immune response characterized by increasing concentrations of self-antibodies (SAbs) anti-Col-V and anti-Kα1T. We sought to establish the point prevalence of abnormally elevated concentrations of SAbs among patients with pathological gastroesophageal reflux disease (GERD) and/or hiatal hernia undergoing antireflux surgery (ARS).

Methods
For this cross-sectional study, we retrieved a plasma aliquot from the Norton Thoracic Institute BioBank from blood samples that were taken preoperatively from patients who underwent ARS between November 2019 and August 2022. Enzyme-linked immunosorbent assays were employed to detect and quantify anti-Col-V and anti-Kα1T.

Results
Samples from 43 patients (females, n = 34 [79.1%]; mean age, 62 ± 12 years; and mean BMI, 30.5 ± 7 kg/m2) were analyzed. Before ARS, 28 (65.1%, CI95: 50.3–80.0%) patients had abnormally elevated concentrations of anti-Col-V and 19 (44.2%, CI95: 28.7–59.7%) had elevated concentrations of circulating anti-Kα1T. Overall, 13 patients (30.2%) had low (i.e., normal) concentrations of both SAbs, 13 (30.2%) were positive only for one, and 17 (39.5%) were positive for both SAbs.

Conclusion
A relative high point prevalence of abnormally elevated circulating SAbs (i.e., anti-Col-V and/or anti-Kα1T) before ARS was found. This result suggests clinically unsuspected pulmonary parenchymal injury secondary to GERD-related aspiration. Further studies are required to confirm this hypothesis and to identify alternative non-invasive early biomarkers of GERD-related lung damage.
Investigating Mechanical Characteristics of Rocks Under Freeze–Thaw Cycles Using Grain-Based Model
Authors: Huang Chenchen , Zhu Cheng , Ma Yifei 
Published: September 2024

AbstractBased on the discrete element method (DEM), a water-contained grain-based model (GBM) is developed in this study to evaluate the effects of freeze–thaw cycles (FTCs) on the mechanical characteristics of the rock. A set of freeze–thaw and uniaxial compression tests is carried out to explore the impact of micro damage caused by FTCs on the mechanical prosperities of rock samples. By monitoring the development and distribution of micro-cracks during freeze–thaw test and uniaxial compression test, the damage mechanism of FTCs is revealed from a microscopic perspective, which shows that FTCs deteriorate the strength and brittleness parameters as exponential functions. The parametric analysis is carried out to explore the influence of porosity and mineral components on the mechanical behaviors of rock against freeze–thaw and uniaxial loadings. Based on the parametric analysis results, it is found that UCS, Young’s modulus, and total strain energy at peak stress decrease with the increase of porosity and clay content, which emphasizes the contributions of porosity and mineral components on the mechanical properties of rock samples. It is proved that the water-contained grain-based model developed in this study can capture the damage caused by FTCs on the mechanical performance of rock from a microscopic perspective, which provides novel perspectives on the phenomenon of rock degradation in response to fluctuations in temperature.

Published: September 2024

AbstractImmunocompromised patients are prone to recurrent Campylobacter infections. We report a case of recurrent multi-drug resistant Campylobactor jejuni bloodstream infections in a Bruton’s X-linked agammaglobulinemia patient with prolonged ertapenem treatment. The isolate from the fifth recurrence developed carbapenem resistance, which is associated with mutations in a porin gene porA, and promoter changes and duplication of chromosomal blaOXA-61 gene. Combination therapy using cefepime and doxycycline (later switched to moxifloxacin) cleared the infection.
Adoption of agroforestry systems by smallholders’ farmers in the Sudano-Sahelian zones of Mali and Burkina Faso, West Africa

Published: September 2024

AbstractDespite the well-known potential of agroforestry systems to sustain livelihoods and ecosystem services, their targeted adoption in the Sudano-Sahelian zone of West Africa is low. To address this, we used questionnaires with 279 farmers to understand their socio-economic characteristics determining the adoption of agroforestry technologies and to record the preferred tree species in the Koulikoro region of Mali and West-Central region of Burkina Faso. The result of a binary logistic regression showed that income, off farm activities, average number of owned sheep, cooperative membership, forage security, and maintained trees and shrubs fostered the adoption of agroforestry technologies. Contrarily, the adoption of agroforestry technologies was negatively influenced by household size and crop yield. Our data show that agroforestry parklands are the most popular agroforestry technology. The most common agroforestry tree species in the study region was Vitellaria paradoxa C. F. Gaertn. The dominance of V. paradoxa within these parklands may be partly explained by the tree’s adaptation to severe drought and fire hazards, which are common to the study region. The study also revealed that smallholder farmers in Mali maintained trees on farms mainly for food security, whereas in Burkina Faso trees were mainly kept for maintaining soil fertility. We conclude that in all initiatives aimed at promoting the adoption of agroforestry in the study region, efforts should be made to consider farmers’ socioeconomic characteristics, tree preferences, and perceptions (as identified in this study).
