Published: June 2023

AbstractBackground and ObjectivesA spectrum of blood‐borne infectious agents may be transmitted through transfusion of blood components from asymptomatic donors. Despite the persistence of polyomaviruses in blood cells, no studies have been conducted in Argentina to assess the risk of transfusion infection.Materials and MethodsWe investigated BKPyV and JCPyV in 720 blood donors, using polymerase chain reaction (PCR) for a region of T antigen common to both viruses. Positive T‐antigen samples were subjected to two additional PCR assays targeting the VP1 region. Viral genotypes were characterized by phylogenetic analysis.ResultsPolyomaviruses were detected in 1.25% (9/720) of the blood samples selected; JCPyV was identified in 0.97% (7/720) and BKPyV in 0.28% (2/720) of them. Phylogenetic analysis showed that the JCPyV sequences clustered with 2A genotype and Ia of BKPyV.ConclusionThis study describes for the first time the prevalence of polyomavirus DNA in blood donors of Córdoba, Argentina. The polyomavirus DNAemia in healthy populations suggests that those viruses are present in blood components eligible for transfusion. Therefore, the epidemiological surveillance of polyomavirus in blood banks might be incorporated into haemovigilance programmes, to determine the infectious risk and implement newer interventions to ensure the safety of blood supplies, if required.
Analytical and Numerical Investigations of Circular Metal Foam Sandwich Tube Under Free Inversion
Authors: Bai Jinwen , Zhang Jianxun 
Published: June 2023

Abstract
The foam sandwich tube contains inner and outer tubes and filling foam. The foam sandwich tube is widely used in engineering, due to its lightweight, high specific strength, energy absorption, and other excellent characteristics. In this paper, the free inversion of the circular metal foam sandwich tube (CMFST) under axial loading is studied analytically and numerically. The plastic deformation occurs in the CMFST, and its main deformation modes include circumferential expansion, radial bending of the CMFST, and compression of the metal sandwich foam. An analytical model for the free inversion of the CMFST under axial loading is established, considering metal tube expansion, the radial bending of metal circular tube wall, and metal foam compression. The commercial abaqus software is adopted to numerically study the free inversion behavior of the CMFST. The analytical predictions agree well with the numerical ones. It is shown that the specific energy absorption (SEA) of the CMFST under free inversion is significantly better than the empty tube. When the non-dimensional foam strength is 0.05, the SEA of the CMFST under free inversion is 107.68% higher than the empty tube. Thus, the metal foam sandwich tube under free inversion is an excellent energy-absorbing device.

Published: June 2023

Abstract
The progress of additive manufacturing (AM) within the last few decades has been phenomenal, progressing from a polymeric technique to a method for manufacturing metallic aerospace components. We take a look at various technological advances which have helped paved the way for this growth, focussing on European input, as currently, 54% of AM machines are sold by European manufacturers (Wohlers, Campbell, Diegel, Kowen, Mostow, and Fidan, 2022, “Wohlers Report 2022: 3D Printing and Additive Manufacturing Global State of the Industry,” Wohlers Associates, ASTM International, Fort Collins, Colo., Washington, DC). We take deep dives into several critical topics including sensing and monitoring, preheating, and multi-laser technology and illustrate how these develop from research ideas into industrial products. Finally, an outlook is provided, highlighting the topics currently gaining research traction, and which are expected to be the next key breakthroughs.

Possibility of Clear Air Turbulence Localization with Lidar
Authors: Banakh V. A. , Smalikho I. N. , Zaloznaya I. V. 
Published: June 2023

Abstract
The ranges of the parameters of wind and temperature (refractive) turbulence are estimated corresponding to the four-point scale of turbulence intensity at flight altitudes in the free atmosphere. It is shown that the estimates of both the variance of the radial velocity measured with a coherent lidar in the flight direction and of the structural constant of the refractive index from the lidar measurements of the intensity of refractive turbulence in the flight direction make it possible to judge the potential danger of bumpy flight of aircraft in clear-air turbulence zones ahead of the aircraft.
Repeat corneal collagen cross-linking after failure of primary cross-linking in keratoconus

Published: June 2023

BackgroundPrimary corneal collagen cross-linking (CXL) stabilises 96% of progressive keratoconus. There is limited evidence for the treatment of choice when this fails. We present 10 years of repeat CXL and compare with our published experience of primary CXL to (1) identify perioperative risk factors of primary CXL failure and (2) demonstrate the safety and efficacy of repeat CXL.MethodsPatients undergoing repeat accelerated epithelium-off CXL at St James’s University Hospital, Leeds, UK January 2012–August 2022 were identified through electronic patient record, and compared with a previously published cohort of primary CXL patients at the same site.ResultsTwenty-one eyes underwent repeat CXL. The mean interval between primary and repeat CXL treatments was 47.1 months (SD 22.5). Twenty (95%) eyes stabilised after repeat CXL at a mean follow-up of 29.9 months. These cases were compared with 151 cases of primary CXL from our previous study. Patients failing primary CXL were significantly younger (21.3 years (SD 7.0) vs 26.7 years (SD 6.5), p=0.0008). Repeat CXL and primary CXL induced a similar amount of flattening of Kmax (−1.2 D (SD 3.9) vs −0.7 D (SD 4.4), p=0.22). A small, but clinically insignificant, improvement in best-corrected visual acuity was found in the repeat CXL group (−0.04 (SD 0.17) vs −0.05 (SD 0.13), p=0.04). No complications of repeat CXL were noted.ConclusionYounger age may be associated with failure of primary CXL. Repeat CXL is an effective and safe treatment for progressive keratoconus despite primary CXL.

Published: June 2023

ObjectivesThis review examined the factors influencing communication and engagement with ethnic and racial minority groups in Australia during the COVID-19 pandemic. It aimed to answer two main questions: (1) what communication problems people from these communities typically faced during the pandemic? and (2) what strategies and recommendations were suggested to enhance communication and engagement for ethnic and racial minorities during the current COVID-19 pandemic and any similar events in the future?DesignScoping review.Data sourcesPubMed, EMBASE, Cochrane Library, PsychINFO and CINAHL. Grey literature was searched within organisations’ websites and a Google search of key terms.Eligibility criteria for selecting studiesWe included original research, case studies, reports (including government and charity reports), systematic and scoping articles and literature reviews in English, published from January 2020 to August 2022.Data extraction and synthesisTwo researchers independently assessed the literature for eligibility and extracted data from the included literature. The selected papers were analysed and summarised into themes relevant to the research questions. The final review included 38 studies combining published academic papers and grey literature.ResultsKey themes relating to communication and engagement issues included a lack of trust in authority, a lack of access to information and ineffective communication channels and a lack of timely and culturally responsive materials. To reduce the issues, the papers spoke about the key role of community organisations to provide local support and community leaders as trusted spokespersons. Lastly, key recommendations to reduce inequity and strengthen future pandemic responses focused on the need for collaborations and consultations, increasing the number of bilingual workers and supporting community-led communication efforts.ConclusionsThe insights gained from the activities and experiences documented in this review during the COVID-19 pandemic should be incorporated into future decision-making and interventions to enhance communication and engagement strategies.
Efficacy of vibrotactile positional therapy devices on patients with positional obstructive sleep apnoea: a systematic review and meta-analysis
Authors: ALQarni Abdullah S , Turnbull Chris D , Morrell Mary J , Kelly Julia L 
Published: June 2023

IntroductionVibrotactile positional therapy (PT) devices are a new treatment modality for positional obstructive sleep apnoea (POSA). This review aimed to determine the effect of vibrotactile PT on the Apnoea Hypopnoea Index (AHI) and the percentage of time spent in the supine position (%Tsupine) in patients with POSA, compared with baseline. Secondary aims were to investigate the effect on daytime sleepiness, quality of life and sleep quality.MethodsA systematic review and meta-analysis was performed of randomised controlled trials (RCTs) and cohort studies that investigated the effect of vibrotactile PT in POSA patients. Searches were performed via MEDLINE, CENTRAL and Embase up to 29 October 2022.Results1119 studies were identified, 18 studies met the inclusion criteria (10 RCTs, 8 cohort studies). The use of vibrotactile PT significantly reduced the AHI at follow-up compared with baseline (mean difference (95% CI) −9.19 events/hour (–11.68 to –6.70); p<0.00001). The mean %Tsupine was also significantly reduced (mean difference (95% CI) −32.79% (–38.75% to –26.83%); p<0.00001). The percentage changes in the AHI and %Tsupine were 43% and 70%, respectively. Secondary outcomes were daytime sleepiness, quality of life and sleep indices. These showed minimal change, although follow-up was short.ConclusionVibrotactile PT devices are effective in treating POSA; reducing both AHI and %Tsupine. The effect on sleep quality, daytime sleepiness and disease-specific quality of life was minimal. However, there were limited data and follow-up was often brief, meaning that further research is needed to determine the effect of vibrotactile PT on patient-centred outcomes.PROSPERO registration numberCRD42020188617.
Exact spin polarization of massive and massless particles in relativistic fluids at global equilibrium

Published: June 2023

AbstractWe present the exact form of the spin polarization vector and the spin density matrix of massive and massless free particles of any spin and helicity at general global equilibrium in a relativistic fluid with non-vanishing thermal vorticity, thus extending the known expression at the linear order. The exact form is obtained by means of the analytic continuation of the relativistic density operator to imaginary thermal vorticity and the resummation of the obtained series. The phenomenological implications for the polarization of the $$\Lambda$$

Authors: Shelke Ashwini , B Anupama Prabhu , M Ganesh Balthillaya , Kumaran Senthil D. , G Prabu Raja 
Published: June 2023

Background: Mechanical neck pain (MNP) is one of the most prevalent musculoskeletal pathologies in the present time. Physiotherapy management strategies comprising manual therapy and exercise therapy are routinely administered in patients with MNP. Objective: To compare the immediate effect of craniocervical flexion (CCF) exercise and Mulligan mobilisation on pain, active cervical range of motion (CROM) and CCF test performance in patients with MNP. Methods: This prospective, randomised, single-blinded study involved 26 patients with MNP (16 females; mean age; [Formula: see text] years) randomised to a single session of active CCF exercise (3 sets of 10 repetitions) or Mulligan mobilisation (3 sets of 6–10 repetitions). Pain intensity was measured on a numerical pain rating scale (NPRS), active CROM was measured using CROM device, and CCF test performance with surface electromyography (EMG) from bilateral sternocleidomastoid (SCM) and anterior scalene (AS) muscles recorded pre- and immediately post-intervention by an assessor blinded to the treatment groups. Mann–Whitney U test was used to analyse between groups and Wilcoxon signed rank test was used to analyse within-group significance for pain and CROM, Cochran–Mantel–Haenszel correlation test was used to analyse the CCF test performance on EMG from the bilateral SCM and AS muscles. Results: Comparison between pre- and post-intervention readings revealed statistically significant within-group ([Formula: see text]) and no between-group significant difference for pain, ROM, and CCF test performance, indicating both interventions were equally effective. Conclusion: Patients with MNP who received active CCF exercise or Mulligan mobilisation exhibited similar reduction in pain intensity and increased CROM and CCF test performance post-intervention. Surprisingly, AS surface EMG amplitudes were increased post-intervention in both groups warranting further exploration of its role in neck pain.
Reconstructing the Paleoproterozoic Heart of Nuna, from Fennoscandia to Northeastern Laurentia

Published: June 2023

Abstract
Accurate palaeogeographical reconstructions of past supercontinents are necessary to test models of supercontinent cyclicity, secular variation in plate tectonics and mantle geodynamics. However, numerous factors limit our ability to reconstruct past supercontinents as is evident in the ongoing debates regarding the construction phase and geometry of Earth's most recent supercontinent, late Paleozoic to early Mesozoic Pangaea. An important factor in these debates, and a focus of our study is how best to palinspastically restore, in section and in plan-view, the orogenic belts along which supercontinents were stitched together. We utilize the orogenic belts spanning Baffin Island, Greenland and Fennoscandia that are inferred to record the assembly of the Paleoproterozoic supercontinent Columbia to test the accepted reconstruction of the Nuna core of Columbia. We show that as reconstructed in the Nuna model, each of Baffin Island, Greenland (with some complications) and Fennoscandia are characterized by an older cratonic backstop that gives way to younger accretionary complexes toward the inferred oceanic domain that lay to the south and which is inferred to have closed by subduction beneath northeastern Laurentia–Fennoscandia during Columbia assembly. This southward transition from cratonic backstop to accretionary orogen is a hallmark of upper plates in modern convergent plate margins and is consistent with the construction of the Columbia supercontinent, including its Nuna core, through plate tectonic processes, and provides a broad validation of the Nuna reconstruction and hence for Columbia as a whole. Map view curvature of the cratonic backstops is restricted to long wavelength, open bends consistent with the Archean crust having been characterized by significant lithospheric strength. The more accretionary southern portions of Nuna are, however, characterized by sinuous orogens that developed by oroclinal bending of formerly more linear belts, significantly complicating their palinspastic restoration and rendering detailed correlation of juvenile orogenic belts across Nuna problematic.
Moisture Sorption Behavior and Effects of Temperature, Slice Thickness, and Loading Density on Drying Kinetics of a Local Sweet Potato Cultivar Grown in Bangladesh

Published: June 2023

This study is aimed at investigating the moisture sorption behavior and thin-layer drying kinetics of local sweet potato sada (LSPS) variety slices. The sweet potato tubers were sliced at 3, 5, and 7 mm and dried at temperatures of 45, 55, and 62°C at a constant air velocity of 0.6 m/sec in a laboratory-scale cabinet dryer. The BET (Brunauer, Emmet, and Teller) and GAB (Guggenheim-Anderson-De Bore) models were applied to fit the sorption data. Fick’s diffusion equation was used to calculate the drying rate constant and effective moisture diffusivity. Our current result reveals that LSPS exhibited an isotherm with a sigmoid (type II) shape, and the GAB model was more goodness of fit than the BET model to clarify the adsorption isotherm of LSPS. The drying time increased with increasing slice thickness but reduced with increasing drying temperature. The drying rate constant for thin-layer drying decreased with an increase in slice thickness but increased with increasing drying temperature. The loading density with two different shapes (French cut and cube cut) also affected the drying rate constant, which decreased with the increase in loading density. Using statistical parameters, five thin-layer drying models were applied to fit the drying data. The findings indicated that the logarithmic model for 45-55°C and the Page model for 62°C were the most suitable models for explaining the drying behavior of LSPS slices. The effective moisture diffusivity increased with increasing slice thickness and drying temperature, ranging from

m2/s over the temperature range studied. The activation energy also increased with increasing slice thickness, and the values were 5.55 and 7.39 kJ/mol for 3 and 5 mm slices, respectively. The findings suggested that slice thickness, drying temperature, and sample loading density on cabinet dryer trays affect the drying kinetics of sweet potato slices.
Between Preaching and Judging: the Muslim Brotherhood and the Predicament of takfīr (1960s–1980s)
Authors: Elsässer Sebastian 
Published: June 2023

Abstract
Both as a slogan and a book, “Preachers, not Judges” has long dominated academic narratives about the Muslim Brotherhood’s turn towards ‘moderation’ in the 1970s and 1980s. However, upon examination, several commonplace assumptions about “Preachers, not Judges” do not hold. Firstly, the Muslim Brotherhood never renounced takfīr as a basic doctrine. It only debated different ways of implementing this doctrine in practice. Secondly, “Preachers, not Judges” was much less clear and authoritative as a doctrinal statement than often assumed. It is better understood as a tactical manoeuvre aimed at avoiding splits within the movement. Based primarily on a new and comprehensive survey of contemporary sources from the 1970s, this article will propose a revised understanding of Muslim Brotherhood discourse on preaching, judging, and the doctrine of takfīr that remains relevant until the present day.
La circulation des modèles bibliques entre chrétiens et juifs au Moyen Âge: L’exemple de la figure de Rachel
Authors: Neyrinck Axelle 
Published: June 2023

Résumé
L’article porte sur la figure de Rachel et les modes d’appropriation variés de la matriarche en contexte chrétien. Cette étude de cas permet d’observer la circulation d’un type biblique dans un contexte de relations interculturelles dissymétriques. Il ne s’agit pas d’esquisser une histoire des moyens techniques de cette circulation mais de montrer que celle-ci dépend de la mutabilité de la figure de Rachel, c’est-à-dire de sa capacité à prendre sens dans des contextes et des sources variées. Comme d’autres figures bibliques, elle fait l’objet d’une lutte d’appropriation entre juifs et chrétiens aux premiers siècles de notre ère. À l’époque carolingienne, l’exégèse chrétienne en fait le typus Ecclesiae; à l’époque grégorienne, elle devient mater Ecclesia, et constitue une “image ecclésiologique,” à l’instar de la Vierge. Dans quelques sources chrétiennes, elle est même appelée “vierge.” Ainsi, Rachel est “marianisée” dans la culture chrétienne majoritaire, ce qui n’est pas sans effet sur les conceptions juives de Rachel à partir du onzième siècle.
Biodiversity, ecology, and taxonomy of sediment-dwelling Dendrophylliidae (Anthozoa, Scleractinia) in the Gulf of Thailand

Abstract
Dendrophylliidae represents one of the most speciose families of scleractinian coral, expressing a wide range of morphological and ecological traits. Recent phylogenetic analyses of the family have indicated that several conventional genera are in need of revision. In the Gulf of Thailand, dendrophylliids are predominantly found on hard-substrate reefs and pinnacles, or on soft-substrate habitats. Soft-substrate habitats in the Gulf of Thailand have been shown to host unique species assemblages and faunal ecology. Here we provided an updated phylogenetic hypothesis for the Dendrophylliidae based on newly sequenced species, and analyses integrating morphology, genetics and ecology. High-resolution Micro-ct was used to create digital versions of the studied species, allowing for non-destructive examination of internal and external features. Our findings allowed for a taxonomic assessment of the genera Heteropsammia and Tubastraea, with the species Balanophyllia (Eupsammia) stimpsonii, moved to the genus Tubastraea. They also support the polyphyly of Dendrophyllia and Cladopsammia. In-situ surveys provided population-density information for four dendrophylliid species from soft substrate habitats, indicating that the species Heteropsammia moretonensis may be the most widespread within the Gulf of Thailand. These surveys also provided novel ecological documentation associated with these corals, including protocooperative feeding upon a sea pen by Tubastraea stimpsonii comb. nov., and feeding upon other cnidarians by Heteropsammia spp.
