Context. η Tel is an 18 Myr system composed of a 2.09 M⊙ A-type star with an M7-M8 brown dwarf companion, η Tel B. The two objects have a projected separation of 4″.2 (~208 au). This system has been targeted by high-contrast imaging campaigns for over 20 yr, facilitating its orbital and photometric characterization. The companion, η Tel B, both bright and on a wide orbit, is an ideal candidate for a detailed examination of its position and the characterization of its atmosphere.
Aims. To explore the orbital parameters of η Tel B, measure its contrast, and investigate its close surroundings, we analyzed three new SPHERE/IRDIS coronagraphic observations. Our objectives are to investigate the possibility of a circumplanetary disk or a close companion around η Tel B, and characterize its orbit by combining this new data set with archival data acquired in the past two decades.
Methods. The IRDIS data are reduced with state-of-the-art algorithms to achieve a contrast with respect to the star of 1.0 × 10−5 at the location of the companion. Using the NEGative Fake Companion technique (NEGFC), we measure the astrometric positions and flux of η Tel B for the three IRDIS epochs. Together with the measurements presented in the literature, the baseline of the astrometric follow-up is 19 yr.
Results. We calculate a contrast for the companion of 6.8 magnitudes in the H band. The separation and position angle measured are 4″.218 and 167.3 degrees, respectively. The astrometric positions of the companions are calculated with an uncertainty of 4 milliarc-seconds (mas) in separation and 0.2 degrees in position angle. These are the smallest astrometrical uncertainties of η Tel B obtained so far. The orbital parameters are estimated using the Orvara code, including all available epochs. The orbital analysis is performed taking into account the Gaia-HIPPARCOS acceleration of the system. Suppressing its point spread function (PSF), we have produced contrast curves centered on the brown dwarf in order to constrain our detection capabilities for a disk or companions around it.
Conclusions. After considering only orbits that could not disrupt the outer debris disk around η Tel A, our orbital analysis reveals a low eccentric orbit (e ~ 0.34) with an inclination of 81.9 degrees (nearly edge-on) and a semi-major axis of 218 au. Furthermore, we determine the mass of η Tel B to be 48 MJup, consistent with previous calculations from the literature based on evolutionary models. Finally, we do not detect any significant residual pointing to the presence of a satellite or a disk around the brown dwarf. The retrieved detection limits allow us to discard massive objects around η Tel B with masses down to 1.6 MJup at a separation of 33 au.
An approach to the effects of stellar rotation on the theoretical apsidal motion constants
Authors: Claret A. 
Published: May 2024

Aims. The most reliable sources for determining absolute stellar parameters are the double-lined eclipsing binary systems. Some of these systems also show apsidal motion, characterized by the variable log k2. This point grants us the possibility of investigating the stellar interior, specifically the degree of stellar mass concentration. The first studies carried out about four decades ago on this topic showed appreciable discrepancies not only with respect to the comparison between the observed absolute dimensions and their theoretical counterparts, but mainly concerning the degree of mass concentration through the analysis of their apsidal motions. Fortunately, this scenario has been gradually improving with the advances in the quality of observational techniques and advances in the input physics of the evolutionary stellar models (e.g. opacities, thermonuclear reactions, equations of state, numerical techniques). These new developments in the input physics has improved the comparison between observations and the values predicted by theory, including the apsidal motion rates. This progress has lead us to investigate second-order effects such as rotation and dynamic tides. In this paper we deal with the effects of rotation on the degree of mass concentration.
Methods. The stellar models were calculated using the MESA package. The mass range studied here was 0.40–25.0 M⊙ for a generic chemical composition characterized by X = 0.70 and Z = 0.02. The present models were computed without taking into account core overshooting in order to highlight the effects of rotation. Each model was followed from the pre-main sequence until the central hydrogen content is of the order of or less than 0.03, covering the range of masses and evolutionary status of the double-lined eclipsing binaries showing apsidal motion. Regarding the calculation of the internal structure coefficients, we integrated the Radau equation using the fifth-order Runge-Kutta method and a tolerance level of 10−7. As an auxiliary tool, homology transformations have been used to explain, qualitatively, how the equation of state, thermonuclear reactions, and convection impact the degree of mass concentration of the models.
Results. In our past studies on the effects of rotation on log k2 an average correction was used for all models together. For this a small range of masses (2.0, 7.0, 15.0 M⊙) has been used. In the present paper the corrections due to the effects of rotation in log k2 are presented for each mass individually and for three evolutionary phases. This point is particularly important, given that these corrections show a clear dependence on the mass and on the evolutionary status. Such corrections can be easily introduced into the theoretical calculation of apsidal motion rates through a linear equation. A typical correction due to the rotation effects is of the order of −0.03 in log k2.

ZUSAMMENFASSUNGDie Zahl an Patienten, die auf ein Nierenersatzverfahren angewiesen sind, steigt stetig. Die Peritonealdialyse (PD) ist eine Methode zur Nierenersatztherapie, die hinsichtlich der Lebensqualität und Patientenautonomie häufig Vorteile gegenüber der Hämodialyse bieten kann. Allerdings ist die Langzeit-PD mit chronischen Veränderungen der Peritonealmembran wie Fibrose assoziiert, die den Teilchen- und Wassertransport erheblich beeinträchtigen und zum Ultrafiltrationsversagen führen können. Schlimmstenfalls treten schwere Komplikationen wie die enkapsulierende Peritonealsklerose (EPS) auf. In einigen Fällen kommt es sehr früh, d. h. nach etwa 5 Jahren oder weniger, zu Veränderungen, die zu einem Therapieversagen führen, sodass die PD beendet werden muss. Daher ist der möglichst lange Funktionserhalt der Membran von großer Bedeutung. In diesem Beitrag geben wir einen Überblick über Maßnahmen zum peritonealen Langzeiterhalt sowie einen Ausblick auf neue, potenzielle Therapeutika, die zu einer längeren Integrität der Peritonealmembran beitragen könnten.

Published: May 2024

Abstract
Objectives The aim of this study were to measurably detect Bifidobacterium and Scardovia wiggsiae in plaque from severe early childhood caries (S-ECC) and caries-free children and to analyze the interrelation between these bacteria and clinical caries presentation and caries-related factors assessed by questionnaire.
Materials and Methods One-hundred forty supra gingiva plaque samples from children aged between 2 and 5 years were used in this study. There were 70 children in each group. Recorded plaque index, modified gingival index, and decay, missing, and filled tooth (dmft) scores. Parents' attitudes, child's oral hygiene, and diet were assessed by questionnaire. DNA was extracted from plaque samples and quantitative real-time polymerase chain reaction using fluorescent dye was performed.
Results Plaque (p < 0.001) and modified gingival indices (p < 0.001) in the S-ECC group were higher than in the caries-free group. Prevalence of Bifidobacterium (p = 0.004) and S. wiggsiae (p < 0.001) in the S-ECC group was higher than in the caries-free group. The numbers of total bacteria (p = 0.003), Bifidobacterium (p < 0.001), and proportion of Bifidobacterium to total bacteria (p < 0.001) were higher in the S-ECC group. Detections of both bacteria, Bifidobacterium + S. wiggsiae (p < 0.001), were higher in the S-ECC group than in the caries-free group. In the S-ECC group, dmft scores (p < 0.001; p = 0.024) and the modified gingiva index (p = 0.004; p = 0.002) were higher in the presence of Bifidobacterium and S. wiggsiae, respectively. In the S-ECC group, the dmft scores (p = 0.005) and modified gingiva index (p = 0.004) were higher in the presence of both Bifidobacterium + S. wiggsiae. There were positive correlations between the Bifidobacterium level (p = 0.003), the proportion of Bifidobacterium to total bacteria (p = 0.017), and S-ECC. The level of Bifidobacterium (p < 0.001) and ratio of Bifidobacterium to total bacteria (p < 0.001) were correlated with the dmft score and modified gingival index in the S-ECC group. From the questionnaire, S-ECC were associated with major caregiver (p = 0.002), parent education levels (p = 0.02), prolonged bottle-feeding (>18 months) (p = 0.015), night-time feeding (p < 0.001), eating cariogenic snacks (p = 0.019), and frequency of dental visits (p = 0.003).
Conclusions Levels of total bacteria, Bifidobacterium, S. wiggsiae and plaque, and the modified gingival indices were higher in the S-ECC group. Factors associated with S-ECC included the major caregiver, parent education levels, feeding patterns, cariogenic snacks consumption, and frequency of dental visits.

Abstract
Background Structural metadata from the majority of clinical studies and routine health care systems is currently not yet available to the scientific community.
Objective To provide an overview of available contents in the Portal of Medical Data Models (MDM Portal).
Methods The MDM Portal is a registered European information infrastructure for research and health care, and its contents are curated and semantically annotated by medical experts. It enables users to search, view, discuss, and download existing medical data models.
Results The most frequent keyword is “clinical trial” (n = 18,777), and the most frequent disease-specific keyword is “breast neoplasms” (n = 1,943). Most data items are available in English (n = 545,749) and German (n = 109,267). Manually curated semantic annotations are available for 805,308 elements (554,352 items, 58,101 item groups, and 192,855 code list items), which were derived from 25,257 data models. In total, 1,609,225 Unified Medical Language System (UMLS) codes have been assigned, with 66,373 unique UMLS codes.
Conclusion To our knowledge, the MDM Portal constitutes Europe's largest collection of medical data models with semantically annotated elements. As such, it can be used to increase compatibility of medical datasets and can be utilized as a large expert-annotated medical text corpus for natural language processing.
Determining the depth and rate of soil movement down the soil profile using an environmental tracer: a hillslope scale assessment
Authors: Hancock G. R. , Gibson A. , Senanayake I. P. , Cox Tristan 
Published: May 2024

Context Soil materials can be delivered to depth from both in situ and ex situ materials. Here, we examine a hillslope in an agricultural environment that has been used for cropping and cattle grazing for over 150 years and a parallel area where cattle have been excluded for approximately 20 years. The exclusion area is a shelterbelt and also provides ecological services. Aims To quantify the depth and rate of down profile soil movement using the environmental tracer 137Cs at points along a hillslope profile. Methods 137Cs concentration is measured to bedrock at regular intervals both inside and outside a fenced of ecological services area pre-drought (2015) and post-drought (2021). In Australia. 137Cs is the by-product of nuclear weapons use and testing from1945 to 1972. Therefore, this places an age constraint on any labelled soil. Key results Results show that soil materials can move down the soil profile to reach bedrock at decadal time scales. An important finding is that materials from the surface can reach depths of up to 80 cm near the hillslope crest and up to 2.2 m at the base of the hillslope. Conclusions This demonstrates a relatively rapid translocation of surface material. Implications The method provides the ability to quantify the rapid movement of soil components and demonstrates the potential for deep sequestration of soil organic carbon. The results demonstrate the potential for soil amendments and agrochemicals to be rapidly transported to depth. The findings suggest that cattle exclusion has no impact on the movement of soil materials down the profile over the 20-year exclusion period.
Visitor experience as translation
Authors: Neather Robert 
Published: May 2024

Abstract
This paper explores the museum visitor experience as a form of translation. It argues that if a given exhibition can be seen as a cultural translation, then it is also true that the visitor’s reading of that exhibition constitutes a further layer of translation, as the visitor enacts their own transformation of the culture on display. The paper draws on intertextuality as a means to understand the ways in which this transformation occurs. It delineates a three-level typology of intertexts employed by the visitor and considers how the use of such intertexts constructs the visitor’s positionality in regard to the exhibition. The paper focuses on data from a diasporic museum, the Museum of Chinese in America, and applies a methodology involving analysis of TripAdvisor reviews and post-visit diaries to the online museum. The paper concludes that diaspora museums are a case in which the particular nexus of identity issues at work provide a more complex view of the visitor experience as translation.
“So if you’re going fossil hunting, that’s where you should look”
Authors: Sezzi Annalisa , Nocella Jessica Jane 
Published: May 2024

Abstract
Whether directed at adults or children, popularization can be viewed as a process of “translating” and
“recontextualizing” expert discourse for a lay audience. In fact, knowledge dissemination for children appears to entail an
additional form of “translation,” given their limited background knowledge. This “re-translation” often occurs on dedicated
websites based on “edutainment.” While most museum websites function as promotional tools or as agents of knowledge dissemination,
a small number of them are targeted at children and offer texts that insert museum objects in a broader context. By means of a
small case study, this paper explores how knowledge is popularized and presented in two science museum websites: the Natural
History Museum (NHM) in London and OLogy, the science website for children of the American Museum of Natural
History (AMNH) in New York. From a corpus-linguistic and discourse-analysis perspective, our interest lies in how popularization
takes shape in these two websites, the former intended for different age groups and the latter explicitly addressing children.
Quantitative and qualitative results show similarities and dissimilarities, thus accounting for different types of popularization
as forms of translation. The analysis aims to grant insights to translators and interpreters engaged in museum adaptations and
translation of contexts.
Are f(R, Matter) theories really relevant to cosmology?
Authors: Lacombe Osmin , Mukohyama Shinji , Seitz Josef 
Published: May 2024

Abstract
We examine f(R, Matter) theories that directly couple the curvature R or R
μν with the matter sector in the action, in addition to the universal coupling. We argue that if the matter sector includes the Standard Model (SM), such theories are either inconsistent or already excluded by experiments unless they are a rewriting of f(R) gravity or general relativity. If these theories genuinely couple the SM to curvature, they suffer from the presence of ghost states at energies within their domain of application for cosmological purposes. Therefore, we raise questions about their relevance to cosmology. Moreover, if such theories do not include the SM, they should just be seen as scalar-tensor, vector-tensor, …, theories, depending on the additional degrees of freedom. They should thus be studied accordingly.
Axionic defects in the CMB: birefringence and gravitational waves
Authors: Ferreira Ricardo Z. , Gasparotto Silvia , Hiramatsu Takashi , Obata Ippei , Pujolàs Oriol 
Published: May 2024

Abstract
The evidence for a non-vanishing isotropic cosmic birefringence in recent analyses of the
CMB data provides a tantalizing hint for new physics. Domain wall (DW) networks have recently
been shown to generate an isotropic birefringence signal in the ballpark of the measured value
when coupled to photons. In this work, we explore the axionic defects hypothesis in more detail
and extending previous results to annihilating and late-forming networks, and by pointing out
other smoking-gun signatures of the network in the CMB spectrum such as the anisotropic
birefringent spectrum and B-modes. We also argue that the presence of cosmic strings in the
network does not hinder a large isotropic birefringence signal because of an intrinsic
environmental contribution coming from low redshifts thus leaving open the possibility that
axionic defects can explain the signal. Regarding the remaining CMB signatures, with the help of
dedicated 3D numerical simulations of DW networks, that we took as a proxy for the axionic
defects, we show how the anisotropic birefringence spectrum combined with a tomographic approach
can be used to infer the formation and annihilation time of the network. From the numerical
simulations, we also computed the spectrum of gravitational waves (GWs) generated by the network
in the post-recombination epoch and use previous searches for stochastic GW backgrounds in the CMB
to derive for the first time a bound on the tension and abundance of networks with DWs that
annihilate after recombination. Our bounds extend to the case where the network survives until the
present time and improve over previous bounds by roughly one order of magnitude. Finally, we show
the interesting prospects for detecting B-modes of DW origin with future CMB experiments.
Probing Gauss-Bonnet-corrected inflation with gravitational waves
Authors: Mudrunka Kamil , Nakayama Kazunori 
Published: May 2024

Abstract
The low energy effective action of quantum gravity may include the higher curvature terms such as the Gauss-Bonnet term.
The inflaton dynamics may be affected by the Gauss-Bonnet term if there is an inflaton-Gauss-Bonnet coupling.
We show that an inflation model with a simple power law potential is made viable if it is coupled to the Gauss-Bonnet term since the prediction on the scalar spectral index and the tensor-to-scalar ratio are modified.
We further point out that such a model predicts huge amount of gravitational waves at the high frequency range around 100 GHz–100 THz through the perturbative inflaton decay into gravitons induced by the Gauss-Bonnet term.
Thus the spectrum of high frequency gravitational background is a unique feature of the inflation models with a Gauss-Bonnet correction.
