Context. The diverse morphology among protoplanetary disks may result from planet-disk interactions, suggesting the presence of planets undergoing formation. The characterization of disks can provide information on the formation environments of planets. To date, most imaging campaigns have probed the polarized light from disks, which is only a fraction of the total scattered light and not very sensitive to planetary emission.
Aims. We aim to observe and characterize protoplanetary disk systems in the near-infrared in both polarized and total intensity light to carry out an unprecedented study of the dust scattering properties of disks, as well as of any possible planetary companions.
Methods. Using the star-hopping mode of the SPHERE instrument at the Very Large Telescope, we observed 29 young stars hosting protoplanetary disks and their reference stars in the Ks-band polarized light. We extracted disk signals in total intensity by removing stellar light using the corresponding reference star observations, by adopting the data imputation concept with sequential non-negative matrix factorization (DI-sNMF). For well-recovered disks in both polarized and total intensity light, we parameterized the polarization fraction phase functions using a scaled beta distribution. We investigated the empirical DI-sNMF detectability of disks using logistic regression. For systems with SPHERE data in the Y, J, and H bands, we have summarized their polarized color at an approximately 90° scattering angle.
Results. We obtained high-quality disk images in total intensity for 15 systems and in polarized light for 23 systems. The total intensity detectability of disks primarily depends on the host star brightness, which determines adaptive-optics control ring imagery and thus stellar signals capture using DI-sNMF. The peak of polarization fraction tentatively correlates with the peak scattering angle, which could be reproduced using certain composition for compact dust, yet more detailed modeling studies are needed. Most of the disks are blue in polarized J – Ks color and the fact that they are relatively redder as stellar luminosity increases indicates larger scatterers.
Conclusions. High-quality disk imagery in both total intensity and polarized light allows for disk characterizations in the polarization fraction. Combining these techniques reduces the confusion between the disk and planetary signals.

Published: October 2023

Resumen
Introducción Las caídas en población geriátrica son un problema de salud pública, tomando mayor relevancia luego de una fractura de fémur proximal (FFP). El test “timed up and go” (TUG) se ha relacionado al riesgo de caídas y se utiliza en diversas sociedades de geriatría.
Objetivo Evaluar el riesgo de caídas en pacientes con FFP pasado el año de cirugía.
Materiales y Métodos Se realizó un estudio observacional y transversal de pacientes operados por FFP entre enero 2017 y mayo 2020. Se incluyeron pacientes de 60 a 85 años, con un año o más de evolución desde su cirugía. Se excluyeron individuos con enfermedades neurológicas severas y progresivas, IMC > 40, deterioro cognitivo avanzado y con enfermedades o factores mecánicos que pudieran impedir la adecuada evaluación o rehabilitación. Los pacientes fueron citados y se les realizó evaluación clínica, nutricional y radiológica. Posteriormente se midió la fuerza cuadricipital de extremidades inferiores y se aplicaron los test de aceleración vertical y TUG. Los resultados fueron analizados utilizando modelos estadísticos, test de hipótesis y modelos de aprendizaje automático.
Resultados En los modelos de aprendizaje automático las variables de mayor importancia para clasificar y segmentar a los pacientes en bajo o mediano-alto riesgo de caídas fueron la fuerza cuadricipital del lado operado, fuerza cuadricipital del lado contralateral y la aceleración vertical. Por otra parte, en los modelos de regresión lineal, el IMC y aceleración vertical tuvieron efecto significativo positivo y negativo respectivamente.
Conclusión La fuerza extensora cuadricipital, la aceleración vertical y el IMC se relacionan al riesgo de caídas. Este trabajo nos muestra elementos accesibles y de bajo costo para identificar estos factores de riesgo y focalizar los recursos destinados para su prevención.
Arithmetic geometric model for the renormalisation of irrationally indifferent attractors
Authors: Cheraghi Davoud 
Published: October 2023

AbstractIn this paper we build a geometric model for the renormalisation of irrationally indifferent fixed points. The geometric model incorporates the fine arithmetic properties of the rotation number at the fixed point. Using this model for the renormalisation, we build a topological model for the dynamics of a holomorphic map near an irrationally indifferent fixed point. We also explain the topology of the maximal invariant set for the model, and also explain the dynamics of the map on the maximal invariant set.

Abstract

Objective. Different radiation therapy (RT) strategies, e.g. conventional fractionation RT (CFRT), hypofractionation RT (HFRT), stereotactic body RT (SBRT), adaptive RT, and re-irradiation are often used to treat head and neck (HN) cancers. Combining and/or comparing these strategies requires calculating biological effective dose (BED). The purpose of this study is to develop a practical process to estimate organ-specific radiobiologic model parameters that may be used for BED calculations in individualized RT planning for HN cancers. Approach. Clinical dose constraint data for CFRT, HFRT and SBRT for 5 organs at risk (OARs) namely spinal cord, brainstem, brachial plexus, optic pathway, and esophagus obtained from literature were analyzed. These clinical data correspond to a particular endpoint. The linear-quadratic (LQ) and linear-quadratic-linear (LQ-L) models were used to fit these clinical data and extract relevant model parameters (alpha/beta ratio, gamma/alpha, d
T and BED) from the iso-effective curve. The dose constraints in terms of equivalent physical dose in 2 Gy-fraction (EQD2) were calculated using the obtained parameters. Main results. The LQ-L and LQ models fitted clinical data well from the CFRT to SBRT with the LQ-L representing a better fit for most of the OARs. The alpha/beta values for LQ-L (LQ) were found to be 2.72 (2.11) Gy, 0.55 (0.30) Gy, 2.82 (2.90) Gy, 6.57 (3.86) Gy, 5.38 (4.71) Gy, and the dose constraint EQD2 were 55.91 (54.90) Gy, 57.35 (56.79) Gy, 57.54 (56.35) Gy, 60.13 (59.72) Gy and 65.66 (64.50) Gy for spinal cord, optic pathway, brainstem, brachial plexus, and esophagus, respectively. Additional two LQ-L parameters d
T were 5.24 Gy, 5.09 Gy, 7.00 Gy, 5.23 Gy, and 6.16 Gy, and gamma/alpha were 7.91, 34.02, 8.67, 5.62 and 4.95.Significance. A practical process was developed to extract organ-specific radiobiological model parameters from clinical data. The obtained parameters can be used for biologically based radiation planning such as calculating dose constraints of different fractionation regimens.
A Sensibility of Humour
Authors: Walker Zoe 
Published: October 2023

Abstract
What does it say about you if you enjoy sexist humour? One answer to this question holds that finding sexist humour funny reveals that you have sexist beliefs, whilst another holds that it reveals nothing deeper about you at all. I argue that neither of these answers are correct, as neither can capture the feeling of unwilling complicity we often get from enjoying sexist jokes. Rather, we should navigate between these two positions by understanding the sense of humour as a kind of sensibility or taste, analogous to Anne Eaton’s account of erotic taste. This allows for a fleshing out of the purely belief-centred understanding of the sense of humour, adding emotional, perceptual and motivational aspects to it. Finally, I propose that one’s sense of humour is shaped the representations one engages with, which suggests a possible avenue for habituating it in a more egalitarian direction.

Abstract
The Task Force on Global Guidelines for Falls in Older Adults has put forward a fall risk stratification tool for community-dwelling older adults. This tool takes the form of a flowchart and is based on expert opinion and evidence. It divides the population into three risk categories and recommends specific preventive interventions or treatments for each category. In this commentary, we share our insights on the design, validation, usability and potential impact of this fall risk stratification tool with the aim of guiding future research.

Is it really ever ‘just acne’? Considering the psychodermatology of acne
Authors: Hughes Olivia , Bewley Anthony 
Published: October 2023

Abstract
Acne can create a significant burden for people of all ages. However, the psychological consequences might often be overlooked. This review comments on recent evidence in the field of psychodermatology, to highlight the importance of considering a person's mental health in the treatment of acne. A range of presenting issues are discussed, and cases of underserved patients needing additional considerations are highlighted. This article considers how the psychological sequelae can contribute to the pathogenesis of acne, and discusses how psychotherapeutic approaches can be of benefit to people experiencing appearance-related distress. Importantly, attention is paid to the need for clinicians to assess a patient’s wellbeing alongside their physical symptoms. In doing this, early intervention can be facilitated if psychological comorbidities are present, with referral to appropriate specialist services, where available. To improve treatment outcomes, the skin and the mind must be addressed together in a multidisciplinary approach to dermatology care.
How China Perceives European Strategic Autonomy: Asymmetric Expectations and Pragmatic Engagement
Authors: Yang Na 
Published: October 2023

Abstract
Intensified strategic competition between China and the US and the outbreak of the Russia–Ukraine conflict have polarised international attention on the promotion and prospects for European strategic autonomy (ESA). This change in the international and regional environment raises an important question: How does ESA affect China–EU relations? Answering it requires clarification of the main impacts of ESA promotion on China–EU relations. These include: the EU’s reduced dependence on key materials and technologies from certain countries, and the formulation and expression, in line with core EU interests, of an independent stance and policies on China; China’s adjustment of its European Strategy; and persistent external pressure from the United States. Starting from its particular interests, the EU has, to some extent, independently assessed and accordingly refined its relations with China, having pursued cooperation in global public welfare governance and other areas of similarly low ideological significance, and pragmatically explored ways of moderating competition and enhancing cooperation with China. Fields highly sensitive to geopolitical influence, or which involve key technologies and globally important supply chains, are those wherein China is treated as a competitor. Upon analysis, it can be concluded that the EU’s most consistent approach to its goals of strategic autonomy is that of maintaining an alliance with the United States while avoiding full dependence on it, and competing with China in key areas that allow leeway for practical cooperation.
Cytosponge procedures produce fewer respiratory aerosols and droplets than esophagogastroduodenoscopies

Published: October 2023

Summary
Esophagogastroduodenoscopies (EGD) are aerosol-generating procedures that may spread respiratory pathogens. We aim to investigate the production of airborne aerosols and droplets during Cytosponge procedures, which are being evaluated in large-scale research studies and National Health Service (NHS)implementation pilots to reduce endoscopy backlogs. We measured 18 Cytosponge and 37 EGD procedures using a particle counter (diameters = 0.3–25 μm), taking measurements 10 cm from the mouth. Two particle count analyses were performed: whole procedure and event-based. Direct comparison with duration-standardized EGD procedures shows that Cytosponge procedures produce 2.16× reduction (P &lt; 0.001) for aerosols and no significant change for droplets (P = 0.332). Event-based analysis shows that particle production is driven by throat spray (aerosols: 138.1× reference, droplets: 16.2×), which is optional, and removal of Cytosponge (aerosols: 14.6×, droplets: 62.6×). Cytosponge burping produces less aerosols than EGD (2.82×, P &lt; 0.05). Cytosponge procedures produce significantly less aerosols and droplets than EGD procedures and thus reduce two potential transmission routes for respiratory viruses.

Abstract
To raise the quality of clinical artificial intelligence (AI) prediction modelling studies in the cardiovascular health domain and thereby improve their impact and relevancy, the editors for digital health, innovation, and quality standards of the European Heart Journal propose five minimal quality criteria for AI-based prediction model development and validation studies: complete reporting, carefully defined intended use of the model, rigorous validation, large enough sample size, and openness of code and software.

Abstract

Aims
Left atrial catheter ablation is well established in patients with symptomatic atrial fibrillation (AF) but associated with risk of embolism to the brain. The present analysis aims to assess the impact of diffusion-weighted imaging (DWI) slice thickness on the rate of magnetic resonance imaging (MRI)–detected ischaemic brain lesions after ablation.

Methods and results
AXAFA-AFNET 5 trial (NCT02227550) participants underwent MRI using high-resolution (hr) DWI (slice thickness: 2.5–3 mm) and standard DWI (slice thickness: 5–6 mm) within 3–48 h after ablation. In 321 patients with analysable brain MRI (mean age 64 years, 33% female, median CHA2DS2-VASc 2), hrDWI detected at least one acute brain lesion in 84 (26.2%) patients and standard DWI in 60 (18.7%; P &lt; 0.01) patients. High-resolution diffusion-weighted imaging detected more lesions compared to standard DWI (165 vs. 104; P &lt; 0.01). The degree of agreement for lesion confirmation using hrDWI vs. standard DWI was substantial (κ = 0769). Comparing the proportion of DWI-detected lesions, lesion distribution, and total lesion volume per patient, there was no difference in the cohort of participants undergoing MRI at 1.5 T (n = 52) vs. 3 T (n = 269).

Conclusion
The pre-specified AXAFA-AFNET 5 sub-analysis revealed significantly increased rates of MRI-detected acute brain lesions using hrDWI instead of standard DWI in AF patients undergoing ablation. In comparison to DWI slice thickness, MRI field strength had a no significant impact in the trial. Comparing the varying rates of ablation-related MRI-detected brain lesions across previous studies has to consider these technical parameters. Future studies should use hrDWI, as feasibility was demonstrated in the multicentre AXAFA-AFNET 5 trial.
Evolution, Inheritance, and Strata Formation of the W Chromosome in Duck (Anas platyrhynchos)
Authors: Gu Hongchang , Wen Junhui , Zhao Xiurong , Zhang Xinye , Ren Xufang , Cheng Huan , Qu Lujiang 
Published: October 2023

Abstract
The nonrecombining female-limited W chromosome is predicted to experience unique evolutionary processes. Difficulties in assembling W chromosome sequences have hindered the identification of duck W-linked sequences and their evolutionary footprint. To address this, we conducted three initial contig-level genome assemblies and developed a rigorous pipeline by which to successfully expand the W-linked data set, including 11 known genes and 24 newly identified genes. Our results indicate that the W chromosome expression may not be subject to female-specific selection; a significant convergent pattern of upregulation associated with increased female-specific selection was not detected. The genetic stability of the W chromosome is also reflected in the strong evolutionary correlation between it and the mitochondria; the complete consistency of the cladogram topology constructed from their gene sequences proves the shared maternal coevolution. By detecting the evolutionary trajectories of W-linked sequences, we have found that recombination suppression started in four distinct strata, of which three were conserved across Neognathae. Taken together, our results have revealed a unique evolutionary pattern and an independent stratum evolutionary pattern for sex chromosomes.
Internal versus external knowledge sourcing of organizational rules: an exploratory study of CPGs in a healthcare organization
Authors: Zhu Kejia , Schulz Martin 
Published: October 2023

Abstract
In this study, we examine how organizational rules source knowledge. By knowledge sourcing of a rule, we mean the formation of reference ties from the rule to knowledge sources located outside of the focal rule. Rules can source knowledge from sources within the organization (e.g., other rules) and outside (e.g., research publications, policies, standards, etc.). Our theoretical model proposes that knowledge sourcing of rules is driven by inherent incompleteness of rules as a result of bounded rationality of rule makers and rule making process. Incomplete rules can lead to experiences of insufficient rule knowledge, termed “knowledge gaps,” which are shaped by rule dynamics at the levels of individual rules, the rule system, and rule networks. Our theoretical model leads to several hypotheses that we test with longitudinal archival data of clinical practice guideline (CPG) changes in a Canadian healthcare organization. The findings support our theoretical model of incomplete organizational rules which encounter knowledge gaps and close them through internal and external knowledge sourcing. The theoretical and practical implications of the findings are discussed.
