AbstractRespiratory tract infections are a major cause of morbidity and mortality worldwide in young children. Concepts such as the gut-lung axis have highlighted the impact of microbial communities at distal sites in mediating disease locally. However, little is known about the extent to which microbial communities from multiple body sites are linked, and how this relates to disease susceptibility. Here, we combine 16S-based rRNA sequencing data from 112 healthy, term born infants, spanning three body sites (oral cavity, nasopharynx, gut) and the first six months of life. Using a cross-niche microbial network approach, we show that, already from the first week of life on, there is a strong association between both network structure and species essential to these structures (hub species), and consecutive susceptibility to respiratory tract infections in this cohort. Our findings underline the crucial role of cross-niche microbial connections in respiratory health.

Published: October 2021

Purpose:
This study aimed to (a) identify participant factors associated with hearing aid review (HAR) appointment attendance, (b) investigate whether the completion of self-report survey identifying hearing aid–related problems affects HAR appointment attendance, and (c) investigate whether hearing aid problems and hearing aid management deficiencies are adequately addressed during HAR appointments.

Method:
A prospective cohort study of adult hearing aid owners recruited from a single hearing clinic in Western Australia. Potential participants were invited to an annual HAR appointment via postal letter. The invitation included a paper-based self-report survey evaluating either (a) hearing aid problems, (b) hearing aid management skills, or (c) hearing aid outcomes, depending on which intervention/control group the potential participants were assigned to, and a reply paid addressed envelope. Two months later, potential participants were sent all three paper-based self-report surveys, irrespective of whether they had attended or not attended an HAR appointment.

Results:
(a) There was no significant difference in gender or source of funding for hearing services between HAR appointment attendees and nonattendees. HAR nonattendees lived a greater distance from their clinic and were younger than attendees. (b) Survey completion did not influence HAR appointment attendance rates. (c) A significant reduction in individuals' self-reported hearing aid problems was recorded following the attendance at the HAR appointment. No significant changes in hearing aid management skills or overall hearing aid outcomes were detected.

Conclusions:
Long travel distances may be a barrier to attendance at review appointments. HAR appointments appear to be effective in improving hearing aid problems.

Context.Due to their scarcity, microlensing events in the Galactic disk are of great interest and high-cadence photometric observations, supplemented by spectroscopic follow-up, are necessary for constraining the physical parameters of the lensing system. In particular, a precise estimate of the source characteristics is required to accurately measure the lens distance and mass.Aims.We conducted a spectroscopic follow-up of microlensing event Gaia19bld to derive the properties of the microlensing source and, ultimately, to estimate the mass and distance of the lens.Methods.We obtained low- and high-resolution spectroscopy from multiple sites around the world during the course of the event. The spectral lines and template matching analysis has led to two independent, consistent characterizations of the source.Results.We found that the source is a red giant located at ~8.5 kpc from the Earth. Combining our results with the photometric analysis has led to a lens mass ofMl~ 1.1 M⊙at a distance ofDl~ 5.5 kpc. We did not find any significant blend light in the spectra (with an upper detection limit ofV≤ 17 mag), which is in agreement with photometric observations. Therefore, we cannot exclude the possibility that the lens is a main-sequence star. Indeed, we predict in this scenario a lens brightness ofV~ 20 mag, a value that would make it much fainter than the detection limit.
Disentangling the optical AGN and host-galaxy luminosity with a probabilistic flux variation gradient
Authors: Gianniotis N. , Pozo Nuñez F. , Polsterer K. L. 
Published: October 2021

Context.We present a novel probabilistic flux variation gradient (PFVG) approach to separate the contributions of active galactic nuclei (AGN) and host galaxies in the context of photometric reverberation mapping (PRM) of AGN.Aims.We explored the ability of recovering the fractional contribution in a model-independent way using the entire set of light curves obtained through different filters and photometric apertures simultaneously.Methods.The method is based on the observed “bluer when brighter” phenomenon that is attributed to the superimposition of a two-component structure; the red host galaxy, which is constant in time, and the varying blue AGN. We describe the PFVG mathematical formalism and demonstrate its performance using simulated light curves and available PRM observations.Results.The new probabilistic approach is able to recover host-galaxy fluxes to within 1% precision as long as the light curves do not show a significant contribution from time delays. This represents a significant improvement with respect to previous applications of the traditional FVG method to PRM data.Conclusions.The proposed PFVG provides an efficient and accurate way to separate the AGN and host-galaxy luminosities in PRM monitoring data. The method will be especially helpful in the case of large upcoming photometric survey telescopes such as the public optical/near-infrared Legacy Survey of Space and Time (LSST) at theVera C. RubinObservatory. Finally, we have made the algorithms freely available as part of our Julia PFVG package.
Revisiting TrES-5 b: departure from a linear ephemeris instead of short-period transit timing variation

Published: October 2021

Aims. The orbital motion of the transiting hot Jupiter TrES-5 b was reported to be perturbed by a planetary companion on a nearby orbit. Such compact systems do not frequently occur in nature, and investigating their orbital architecture could shed some light on the formation processes of hot Jupiters.
Methods. We acquired 15 new precise photometric time-series for 12 transits of TrES-5 b between June 2019 and October 2020 using 0.9–2.0 m telescopes. The method of precise transit timing was employed to verify the deviation of the planet from the Keplerian motion.
Results. Although our results show no detectable short-time variation in the orbital period of TrES-5 b and the existence of the additional nearby planet is not confirmed, the new transits were observed about two minutes earlier than expected. We conclude that the orbital period of the planet could vary on a long timescale. We found that the most likely explanation of the observations is the line-of-sight acceleration of the system’s barycentre caused by the orbital motion induced by a massive, wide-orbiting companion.

ResumoA população brasileira está envelhecendo, e com isso aumenta a prevalência de doenças crônico-degenerativas, dentre elas a osteoporose. O diagnóstico e tratamento da osteoporose teve avanços significativos na última década. O ortopedista e traumatologista não pode mais se deter apenas no tratamento cirúrgico da fratura osteoporótica. É extremamente importante que saibamos: 1) quais fatores de risco avaliar, podendo ser utilizada a ferramenta Fracture Risk Assesment Tool (FRAX, na sigla em inglês); 2) quais exames complementares solicitar, como densitometria, radiografia da coluna e bacia, exames de sangue e urina, e até mesmo biópsia óssea; 3) quais suplementos utilizar, como cálcio e magnésio, vitaminas D e K; 4) quais medicamentos prescrever, antirreabsortivos ou formadores, janelas terapêuticas e eventos adversos.

Resumo
Objetivo O tratamento das fraturas da tíbia complicadas por síndrome compartimental afeta o tratamento e o resultado funcional dos pacientes devido às complicações associadas à fasciotomia. O objetivo deste estudo é diferenciar a síndrome compartimental iminente/incompleta (SCI) da síndrome compartimental aguda (SCA) estabelecida nas fraturas tibiais, para avaliar o resultado da fixação do aparelho de Ilizarov nos pacientes fraturados e com SCI, que não foram submetidos à fasciotomia.
Métodos Após o estabelecimento dos critérios de inclusão e exclusão, 19 pacientes foram incluídos no estudo de janeiro de 2007 a dezembro de 2017. Todos eram do sexo masculino, com média de idade de 42,3 ± 11,38 anos. Todos esses pacientes foram tratados com a fixação do aparelho de Ilizarov, de acordo com o protocolo médico e cirúrgico estabelecido neste estudo.
Resultados O acompanhamento médio dos nossos 19 pacientes foi de 47 ± 41,5 meses. O tempo médio de aplicação do fixador circular foi de 3,7 ± 1,7 dias. No total, 3 (16,7%) desses pacientes não apresentaram consolidação. Não houve complicações nas partes moles ou neurovasculares no pós-operatório imediato. A consolidação ocorreu finalmente em todos os pacientes, sem prejuízo da mobilidade e sem sequela de síndrome compartimental.
Conclusão O fixador circular de Ilizarov pode ser utilizado no tratamento dos pacientes com fraturas tibiais com SCI, e evita a fasciotomia, com suas várias complicações de infecção e não consolidação. O resultado é um número menor de procedimentos cirúrgicos e uma reabilitação mais rápida. Os cirurgiões devem diferenciar cuidadosamente a SCA e a SCI, pois, nesses pacientes, os resultados clínicos e funcionais variam significativamente. Fasciotomias desnecessárias devem ser evitadas.

Genomic selection combined with in vitro embryo production (IVEP) with oocytes from heifer calves provides a powerful technology platform to reduce generation interval and significantly increase the rate of genetic gain in cattle. The ability to obtain oocytes with developmental competence from calves has been recognised for more than 60 years. There is renewed interest in the potential of this reproductive technology as the beef and dairy industries seek to identify and multiply animals that satisfy consumer demand for efficient utilisation of natural resources, with minimal environmental impact and high product quality. Heifer calves show a good follicular response to FSH stimulation and oocytes can be recovered by ovum pick-up (OPU). However, the efficiency of OPU/IVEP remains lower for calves compared with peripubertal heifers and cows, in both indicus (Zebu, Bos indicus) and taurus (Bos taurus) breeds. Indicus cattle generally have more follicles, yield a greater number of oocytes, and have a better IVEP outcome, compared with taurus cattle. The treatment of prepubertal heifers with bovine somatotrophin (bST) and propylene glycol before OPU/IVEP has yet to show a major improvement in embryo production. Holstein (taurus) dairy heifers derived from different reproductive technologies (AI, MOET, OPU/IVEP) showed a similar age at puberty and first-lactation milk production. OPU/IVEP Holstein embryos transferred to beef or dairy cows likewise yielded heifers with the same performance. The gains in productivity that can be achieved with strategic use of OPU/IVEP in heifer calves make this a relevant and highly important reproductive technology in cattle breeding. Ongoing optimisation of the technology is needed for the potential of OPU/IVEP in young donors to be fully realised.

Main text
Four national standards for absorbed dose to water in 60Co gamma radiation at the dose levels used in radiation processing have been compared over the range 0.1 kGy to 50 kGy using alanine dosimeters of the Office of Atoms for Peace (OAP) as transfer dosimeters. The comparison was piloted by the OAP who also participated. Two laboratories from the original six were forced to withdraw due to equipment problems. The results at low doses (0.1 kGy) showed a much wider spread (up to 17%) than at the other doses, most likely as a result of random variations in the alanine readout at OAP at these dose levels. Results in the 0.1 kGy range were excluded from the analysis because the variation between the laboratories' doses is overshadowed by the variation in the readout of the alanine. Above 1 kGy the results indicated reasonable agreement between the laboratories, with the majority of results within 2 % of the reference value. All of these results were within two combined standard uncertainties of the reference value, with the exception of the INER at 50 kGy point which was within three combined standard uncertainties. Within the stated uncertainties, the results establish the equivalence of the laboratories at radiation processing levels, for the range in which they participated: NIS (3 - 10) kGy, NIM (3 - 30) kGy, INER (3 - 50) kGy, OAP (3 - 50) kGy.

Gravitational leptogenesis in teleparallel and symmetric teleparallel gravities *
Authors: Li Mingzhe , Mou Yicen , Rao Haomin , Zhao Dehao 
Published: October 2021

Abstract
In this study, we investigate the possibilities of generating baryon number asymmetry under thermal equilibrium within the frameworks of teleparallel and symmetric teleparallel gravities. Through the derivative couplings of the torsion scalar and the non-metricity scalar to baryons, baryon number asymmetry is produced in the radiation dominated epoch. For gravitational baryogenesis mechanisms in these two frameworks, the produced baryon-to-entropy ratio is too small to be consistent with observations. However, the gravitational leptogenesis models within both frameworks have the potential to explain the observed baryon-antibaryon asymmetry.

Abstract
Cross sections of the 58,60,61Ni(n, α)55,57,58Fe reactions were measured at 8.50, 9.50 and 10.50 MeV neutron energies based on the HI-13 tandem accelerator of China Institute of Atomic Energy (CIAE) with enriched 58Ni, 60Ni, and 61Ni foil samples with backings. A twin gridded ionization chamber (GIC) was used as the charged particle detector, and an EJ-309 liquid scintillator was used to obtain the neutron energy spectra. The relative and absolute neutron fluxes were determined via three highly enriched 238U3O8 samples inside the GIC. The uncertainty of the present data of the 58Ni(n, α)55Fe reaction is smaller than most existing measurements. The present data of 60Ni(n, α)57Fe and 61Ni(n, α)58Fe reactions are the first measurement results above 8 MeV. The present experimental data could be reasonably reproduced by calculations with TALYS-1.9 by adjusting several default values of theoretical model parameters.

Authors: Reck S. , Guderian D. , Vermariën G. , Domi A. 
Published: October 2021

Abstract
KM3NeT, a neutrino telescope currently under construction in the Mediterranean Sea, consists of a network of large-volume Cherenkov detectors. Its two different sites, ORCA and ARCA, are optimised for few GeV and TeV-PeV neutrino energies, respectively. This allows for studying a wide range of physics topics spanning from the determination of the neutrino mass hierarchy to the detection of neutrinos from astrophysical sources. Deep learning techniques provide promising methods to analyse the signatures induced by charged particles traversing the detector. This document will cover a deep learning based approach using graph convolutional networks to classify and reconstruct events in both the ORCA and ARCA detector. Performance studies on simulations as well as applications to real data will be presented, together with comparisons to classical approaches.

Published: October 2021

Abstract
In this current investigation, Taguchi method is employed for the improvement of hardness and tensile strength of Friction Stir Processed (FSP) AA7075 with TiO2 reinforcement, which is potentially suited for manufacturing of components in automotive and aerospace applications. Controllable FSP process parameters like Rotational Speed (RS), Traverse Speed (TS), Tool Tilt Angle (TA) and number of passes (No. of pass) are taken into consideration. From Taguchi results, it is identified that No of pass as two, RS as 1400 rpm, TS as 28 mm min−1 and TA as 2° serves the most influencing statistical effect for yielding the hardness. Similarly for Ultimate Strength (UTS), it is identified that No of pass as one, RS as 1400 rpm, TS as 28 mm min−1 and TA of 3° are the influencing parameters. No defect like structure is apparent in the optimized specimens owing to the sufficient heat generation and stirring phenomenon. Besides, sufficient interaction between the plasticized AA7075 matrix and packed TiO2 particles in the SC eliminates the defect formation. Micrographs of the optimized specimens revealed that TiO2 particles are dispersed uniformly in AA7075 matrix with clear interface. Moreover, there is an increase in microhardness for optimized specimen compared to base specimen due to reduced grain size value and homogenous dispersion strengthening mechanism. Meanwhile, the load bearing capacity and work hardening action of TiO2 dispersoids enhances the UTS behavior of the optimized specimen.

Abstract
The current work aims to improve the metal oxide characteristics for mosquito control. Un-doped and Y-doped CuO have been synthesized by simple chemical route. Structural, composition, and morphological properties were characterized by XRD, Raman spectra, EDX, SEM, and TEM techniques. The obtained results revealed that CuO was strongly affected by Y3+ support, in which the crystallite size decreased, and the surface area increased. Larvicidal performance was assessed against Culex pipiens suggesting that the nanocomposite CuO/Y of higher efficiency (LC50 = 7.67 mg /l, R2 = 0.977) compared with pure CuO. Light microscopy and SEM images exhibited larvae malformations owing to using the fabricated nanomaterials.

Published: October 2021

Abstract
The influence of annealing parameters on microstructure and mechanical properties of AISI 1035 carbon steel is analysed in this work. The specimens were full annealed at different temperature ranging from 900 °C to 1020 °C, and further, the evolution of microstructure and mechanical properties in these annealed specimens were analysed. Microstructural analysis shows that the ferrite grains coarsen with annealing, and the grain size was found to significantly increase with annealing temperature. From the toughness tests, it was observed that impact energy of specimens annealed at 1020 °C was found to be twice that of the corresponding value at 900 °C. In addition, the angle of deformation of specimens before fracture was measured on the specimens after impact test. Results shows that specimen annealed at 1020 °C has higher plastic deformation, indicating the higher toughness of these samples compared to those annealed at lower temperatures. This indicates that the ductility of C35 steel increases with annealing temperature.
