Barriers to attendance at a tertiary hospital’s perinatal mortality meeting
Authors: Burke Barbara , Boyd Sophie , McNamara Karen , O’Donoghue Keelin 
Published: September 2022

Abstract
Background
Perinatal mortality multi-disciplinary team meetings (PM-MDTMs) offer a forum for multi-disciplinary discussion of poor perinatal outcomes. They ensure a thorough understanding of individual cases and present an important learning opportunity for healthcare professionals (HCPs). Attendance at PM-MDTMs in this tertiary maternity hospital has been low.

Aims
We aimed to identify barriers which may be targeted to improve attendance and engagement.

Methods
An anonymous questionnaire was developed, and all HCPs invited to participate. Demographic data on respondents was collected, as was knowledge of PM-MDTMs, their purpose and relevance to clinical practice, and barriers to attendance at meetings. A total of 78 responses were obtained and analysed.

Results
Self-reported understanding of the purpose and format PM-MDTMs was high (84.6% (66/78) and 65.4% (51/78), respectively), while only 50% (39/78) of respondents provided an accurate description of either. Only 50% (39/78) reported having attended a meeting in the hospital, of whom 61.5% (24/39) described the correct meeting. Of these, 37.5% (9/24) reported attending regularly and 70.8% (17/24) found the meeting relevant to their clinical practice. Of the 33.33% (26/78) who reported attending a PM-MDTM in another hospital, 73.1% (19/26) accurately described the meeting, 63.1% (12/19) of these attended regularly, and 100% (19/19) found it relevant. Three main qualitative themes emerged as barriers to attendance and were areas for suggested improvements: workload and staffing levels, meeting logistics, and lack of communication and education regarding PM-MDTMs.

Conclusions
Communication regarding PM-MDTMs and their learning opportunities needs to improve. Lack of engagement is likely compounded by high workloads and staffing levels, but these issues should be surmountable.

Published: September 2022

AbstractIn this paper, cordierite-based porous ceramics with magnetic properties have been firstly in-situ synthesized by using MgO, Al2O3, and SiO2 powders as raw materials and Fe3O4 as a functional additive. Combining with the foam freeze casting method, near net size fabrication (total linear shrinkage < 2.86%) of the magnetic porous materials was realized by adjusting the amount of Fe3O4. The porosity, compressive strength, and saturation magnetization of the prepared materials were 83.9%–87.8%, 1.51–2.65 MPa, and 1.2–5.8 emu/g, respectively. The phase composition and microstructure evolutions during sintering were investigated briefly. The results showed that the synthesis temperature of cordierite was lowered about 100 °C due to the addition of Fe3O4. Except for the main phase-cordierite, Mg—Al—Fe spinel and α-Fe2O3 also existed in the final materials. The lattice parameters of the Mg—Al—Fe spinel and the amount of α-Fe2O3 changed obviously with the change in the sintering temperature and Fe3O4 amount, which mainly influenced the magnetic properties of the prepared materials. Thus, a facile fabrication method of the cordierite-based porous ceramics with the magnetic properties has been put forward in this paper.
Medieval Studies after the Global Turn
Authors: Ertl Thomas , Oschema Klaus 
Published: September 2022

Abstract
This contribution seeks to evaluate the influence of the “global turn” on medieval studies, with an accent on the European Middle Ages. Developing global perspectives for the premodern period constitutes a real challenge. First, the very notion of the “Middle Ages” is a Eurocentric concept and its application in non-European contexts can be criticized. Second, while the observation of far-ranging contacts and networks of exchange has opened important avenues for research in premodern history, the quantitative significance of those contacts remains difficult to evaluate. Third, there is an ongoing tension between different visions of (medieval) history’s function in society. Despite these problems, recent contributions to the “global Middle Ages” have opened up new approaches to phenomena that are equally pertinent for European medieval studies. While the global turn might not entirely reshape the history of medieval Europe, it certainly adds important layers and new perspectives to subjects that not only resonate with contemporary interests but have long been a concern of European medieval history, such as migration, commerce, and religion. In spite of the difficulties and challenges (methodological, linguistic, etc.) that it poses, the global turn has the potential to contribute to the development of new thematic approaches and new forms of cooperation in the field of medieval studies.
Analytic torsion for log-Enriques surfaces and Borcherds product
Authors: Dai Xianzhe , Yoshikawa Ken-Ichi 
Published: September 2022

Abstract
We introduce a holomorphic torsion invariant of log-Enriques surfaces of index two with cyclic quotient singularities of type

$\frac {1}{4}(1,1)$

. The moduli space of such log-Enriques surfaces with k singular points is a modular variety of orthogonal type associated with a unimodular lattice of signature

$(2,10-k)$

. We prove that the invariant, viewed as a function of the modular variety, is given by the Petersson norm of an explicit Borcherds product. We note that this torsion invariant is essentially the BCOV invariant in the complex dimension

$2$

. As a consequence, the BCOV invariant in this case is not a birational invariant, unlike the Calabi-Yau case.
Modulating the gut microenvironment as a treatment strategy for irritable bowel syndrome: a narrative review
Authors: Iribarren Cristina , Maasfeh Lujain , Öhman Lena , Simrén Magnus 
Published: September 2022

AbstractIrritable bowel syndrome (IBS) is a disorder of gut–brain interaction with a complex pathophysiology. Growing evidence suggests that alterations of the gut microenvironment, including microbiota composition and function, may be involved in symptom generation. Therefore, attempts to modulate the gut microenvironment have provided promising results as an indirect approach for IBS management. Antibiotics, probiotics, prebiotics, food and faecal microbiota transplantation are the main strategies for alleviating IBS symptom severity by modulating gut microbiota composition and function (eg. metabolism), gut barrier integrity and immune activity, although with varying efficacy. In this narrative review, we aim to provide an overview of the current approaches targeting the gut microenvironment in order to indirectly manage IBS symptoms.
Detrital zircon U–Pb geochronology of the upper Carboniferous strata of Hala’alat Mountain, West Junggar: implications for provenance

Published: September 2022

AbstractDuring late Carboniferous time, the residual ocean basin gradually closed in West Junggar and only a small amount of seawater remained in the Hala’alat Mountain area, where discussions of provenance and tectonics are limited. In this study, LA-ICP-MS U–Pb dating and heavy mineral identification are conducted on the upper Carboniferous tuffaceous sandstones from the Hala’alat and Aladeyikesai formations in the Hala’alat Mountain area. The results reveal the low maturity of the clastic sediments, indicating proximal deposition. The Hala’alat Formation detrital zircons present a single peak (c. 330 Ma). Speculatively, the primary provenance is the Boshchekul–Chingiz Arc, and the secondary sources are the Darbut Tectono-Magmatic Belt and island arcs in the basin. The main peak and provenance of the Aladeyikesai Formation are similar to those of the Hala’alat Formation. Moreover, several age groups, namely, 370–344 Ma, 427–404 Ma and 478–476 Ma, potentially correspond to provenances of the Darbut Tectono-Magmatic Belt, the Boshchekul–Chingiz Arc and the Kujibai–Hongguleleng Ophiolitic Mélange Belt. In addition, the maximum depositional ages of the Hala’alat and Aladeyikesai formations calculated are 314.6 ± 1.54 Ma and 330.8 ± 0.61 Ma, respectively. Comprehensive analysis shows a relatively singular provenance of the Hala’alat Formation. While the provenance of the Aladeyikesai Formation shows inheritance, the provenance area extends northwards to the Kujibai–Hongguleleng Ophiolitic Mélange Belt. Furthermore, the closure of the Junggar Ocean during Carboniferous time caused the potential source region of the Hala’alat Mountain area to migrate northeastwards from Barleik Mountain to Xiemisitai Mountain. This study provides a basis for the analysis of regional geological evolution.
Towards a new philosophical perspective on Hermann Weyl’s turn to intuitionism
Authors: Kish Bar-On Kati 
Published: September 2022

ArgumentThe paper explores Hermann Weyl’s turn to intuitionism through a philosophical prism of normative framework transitions. It focuses on three central themes that occupied Weyl’s thought: the notion of the continuum, logical existence, and the necessity of intuitionism, constructivism, and formalism to adequately address the foundational crisis of mathematics. The analysis of these themes reveals Weyl’s continuous endeavor to deal with such fundamental problems and suggests a view that provides a different perspective concerning Weyl’s wavering foundational positions. Building on a philosophical model of scientific framework transitions and the special role that normative indecision or ambivalence plays in the process, the paper examines Weyl’s motives for considering such a radical shift in the first place. It concludes by showing that Weyl’s shifting stances should be regarded as symptoms of a deep, convoluted intrapersonal process of self-deliberation induced by exposure to external criticism.
In Memoriam: Professor Marc R. de Leval (April 16, 1941–June 26, 2022) - a tribute
Authors: Elliott Martin J. , Deanfield John E. 
Published: September 2022

AbstractThis manuscript is a personal tribute to Professor Marc de Leval from two of his colleagues: Professor Martin J. Elliott and Professor John E. Deanfield. As stated by the authors: “Marc’s career history is presented in the accompanying eulogy from the current Heart & Lung Team at Great Ormond Street Hospital (GOSH), allowing us to highlight Marc’s personal qualities that made him such an inspirational colleague. … Marc was, as we have said, the cardiologist’s surgeon. He was also the surgeon’s cardiologist, bridging the two disciplines and fusing the team. He was delighted by the advent of interventional cardiology and did not see it as a threat or competition, but instead, as appropriate for the well-being of his patients. He recognised how traumatic surgery could be for patients and their families and sought to avoid it whenever possible by alternative treatments. Marc will be remembered with love and admiration by his many patients and their families, whose lives he changed. His technical skill, energy, devotion, humour, intellect and influence will be sorely missed. May he rest in peace.”
Cyclosporin for treatment of refractory multisystemic inflammatory syndrome in a child

Published: September 2022

AbstractMultisystemic inflammatory syndrome in children is an inflammatory condition with multiorgan dysfunction that manifest late in the course of Severe acute respiratory syndrome coronavirus 2 infection. We present a 12-year-old boy with a history of fever, vomiting, diarrhoea, and abdominal pain. He developed shock with ventricular dysfunction and pericardial effusion. He was diagnosed with multisystemic inflammatory syndrome in children and treatment with intravenous immunoglobulins, corticosteroids, and tocilizumab proved to be ineffective. Eventually, the patient responded to cyclosporin-A treatment. Multisystemic inflammatory syndrome in children has been treated with immunoglobulins and glucocorticoids and in refractory cases biologics and cyclosporin-A have been used. Intravenous and oral cyclosporin-A seems to be a safe and effective alternative treatment for refractory multisystemic inflammatory syndrome in children patients.
Antarctic Ice Mass Change (2003–2016) Jointly Estimated by Satellite Gravimetry and Altimetry

Published: September 2022

AbstractAccurate estimation of ongoing Antarctic ice mass change is important to predict future ice mass loss and subsequent sea level rise. Over the past two decades, Antarctic ice mass changes have been observed by the gravity recovery and climate experiment (GRACE) gravity mission, but the low spatial resolution of GRACE has limited understanding of glacial‐scale contributions. In this study, we combine GRACE and altimetry data to obtain mass change estimates with greatly improved spatial resolution. Combined estimates are obtained by a constrained linear deconvolution algorithm used in a previous GRACE study. Satellite altimetry observations are introduced as an a priori and resulting estimates retain the high spatial resolution of satellite altimetry, but when smoothed agree with low resolution GRACE data. These glacial‐scale estimates also agree with ice budget calculations using the input‐output method.
Crustal Structure of the Camamu‐Almada Margin Along the Northeastern Rift Segment of Brazil From an Integration of Deep‐Penetration Seismic Reflection Profiles, Refraction, and Gravity Modeling
Authors: Romito Sean , Mann Paul 
Published: September 2022

AbstractThe Camamu‐Almada segment of the northeastern Brazil rifted‐passive margin covers an area of 22,000 km2 and includes: (a) thin to ultra‐thin metamorphic continental crust; (b) a transitional zone of unknown composition; and (c) Albian and younger oceanic crust. We investigate the structural‐magmatic evolution of the region by interpreting 19,000 line km of two‐dimensional reflection seismic data, 105 offshore well logs, and 15 seismic refraction stations. Interpretation of these data suggests that the 100 km‐wide rifted zone is structurally complex and composed of at least three discrete crustal blocks: (a) 10–40 km‐wide and 4–6 km‐thick zones of hyperextended continental and possibly unroofed lower continental crust with an average density of 2.88 g/cc; (b) two 20 km‐wide sub‐circular zones of exhumed mantle with an average density of 3.1 g/cc; and (c) 40–60 km‐wide and 6–7 km‐thick proto‐oceanic crust that formed in situ. These blocks are similar in thickness and composition to rifted zones described by previous workers along its conjugate margin in Gabon, West Africa, and on the rifted‐passive margin of the western Mediterranean.

Published: September 2022

AbstractThe Formosa Ridge cold seep is among the first documented active seeps on the northern South China Sea passive margin slope. Although this system has been the focus of scientific studies for decades, the geological factors controlling gas release are not well understood due to a lack of constraints of the subsurface structure and seepage history. Here, we use high‐resolution 3D seismic data to image stratigraphic and structural relationships associated with fluid expulsion, which provide spatio‐temporal constraints on the gas hydrate system at depth and methane seepage at modern and paleo seafloors. Gas has accumulated beneath the base of gas hydrate stability to a critical thickness, causing hydraulic fracturing, propagation of a vertical gas conduit, and morphological features (mounds) at paleo‐seafloor horizons. These mounds record multiple distinct gas migration episodes between 300,000 and 127,000 years ago, separated by periods of dormancy. Episodic seepage still seems to occur at the present day, as evidenced by two separate fronts of ascending gas imaged within the conduit. We propose that episodic seepage is associated with enhanced seafloor sedimentation. The increasing overburden leads to an increase in effective horizontal stress that exceeds the gas pressure at the top of the gas reservoir. As a result, the conduit closes off until the gas reservoir is replenished to a new (greater) critical thickness to reopen hydraulic fractures. Our results provide intricate detail of long‐term methane flux through sub‐seabed seep systems, which is important for assessing its impact on seafloor and ocean biogeochemistry.

AbstractWe assimilate atmospheric temperature profiles and column dust optical depth observations from the ExoMars Trace Gas Orbiter Atmospheric Chemistry Suite thermal infrared channel (TIRVIM) into the Mars Planetary Climate Model. The assimilation period is Mars Year 34 Ls = 182.3°–211.4°, covering the onset and peak of the 2018 global dust storm. We assimilated observations using the Local Ensemble Transform Kalman Filter with 36 ensemble members and adaptive inflation; our nominal configuration assimilated TIRVIM temperature profiles to update temperature and dust profiles, followed by dust column optical depths to update the total column dust abundance. The observation operator for temperature used the averaging kernels and prior profile from the TIRVIM retrievals. We verified our analyses against in‐sample TIRVIM observations and independent Mars Climate Sounder (MCS) temperature and dust density‐scaled opacity profiles. When dust observations were assimilated, the root‐mean‐square temperature error verified against MCS fell by 50% during the onset period of the storm, compared with assimilating temperature alone. At the peak of the storm the analysis reproduced the location and magnitude of the peak in the nighttime MCS dust distribution, along with the surface pressure diurnal cycle measured by Curiosity with a bias of less than 10 Pa. The analysis winds showed that, at the peak of the storm, the meridional circulation strengthened, a 125 m s−1 asymmetry developed in the midlatitude zonal jets, the diurnal tide weakened near the equator and strengthened to 10–15 K at midlatitudes, and the semi‐diurnal tide strengthened almost everywhere, particularly in the equatorial lower atmosphere.
A Parametric Study of Performance of Two Solar Wind Velocity Forecasting Models During 2006–2011
Authors: Kumar Sandeep , Srivastava Nandita 
Published: September 2022

AbstractThere is an increasing need for the development of a robust space weather forecasting framework. State‐of‐the‐art MHD space weather forecasting frameworks are based upon the Potential Field Source Surface (PFSS) and Schatten Current Sheet (SCS) extrapolation models for the magnetic field using synoptic magnetograms. These models create a solar wind (SW) background for the simulations using empirical relations of Wang, Sheeley and Arge (WSA), at the inner boundary of heliosphere and have been used to simulate coronal mass ejections for specific cases in previous studies. Besides these MHD frameworks, the Heliospheric Upwind eXtrapolation (HUX) technique can extrapolate SW from inner heliospheric boundaries to L1 and can give a reliable estimate of the SW velocity at L1 comparable to MHD models but in a short computational time. We carried out an extensive parametric study of the performance of the Model1 (PFSS+WSA+HUX) and Model2 (PFSS+SCS+WSA+HUX) for SW velocity prediction at L1. We implemented this framework on 60 Carrington Rotations from CR2047 to CR2107 during 2006–2011, covering the descending and deep minimum phase of solar cycle (SC) 23, and the ascending phase of SC 24. Our results show an unexpected decrease in the performance of the framework during the deep minimum phase of cycle 23, which is attributed to the decrease in the observed coronal hole area. As SC 24 began, this decreasing trend vanished due to an increase in the coronal hole (CH) area at the low and mid‐latitudes, suggesting a good correlation between the performance of the framework and the variation in the CH area.

AbstractIn situ remediation of contaminated groundwater often relies on the installation of a treatment zone (TZ) degrading the contamination. Zero‐valent‐iron (ZVI) is a type of reagent used for this purpose. Adequate delivery of ZVI in the whole target volume is particularly challenging and requires monitoring with high spatial resolution. We present a monitoring tool for imaging the dynamic spreading of ZVI and its associated ionic cloud, using cross‐borehole time‐lapse electrical resistivity tomography (ERT). This tool works in urban areas and is particularly suitable for achieving the required spatial resolution at the scale of the target volume. Groundwater and sediment samples show a consistent spatial and temporal distribution of the remediation cloud with cross‐borehole ERT. Yet, the 2D anomalies observed with cross‐borehole ERT provide a more spatially complete and rapid image of the remediation cloud distribution than if based solely on monitoring screens. At the study site, ZVI injection leads to uneven spreading, clearly documented by cross‐borehole ERT monitoring. The benefit of hydraulic conductivity (K) mapping by cross‐borehole induced polarization (IP) to understand unexpected injection paths (upstream leakage, spreading in preferred pathways) is investigated. A 2D, IP‐based, continuous, and coherent K‐distribution is obtained that compares well with estimations by grain size analyses from the TZ. However, the IP‐based K‐field fails at predicting injection paths, suggesting the creation of pathways during the high‐pressure injection of ZVI. Cross‐borehole time‐lapse ERT is the most promising geophysical tool for performance assessment of in situ remediation involving reagents with conductivity contrast.
