Aggregation behaviors of young nymphs inPanesthia angustipennis spadica(Blaberidae)
Authors: Ito Hiroki , Osawa Naoya 
Published: June 2021

AbstractThe wood‐feeding cockroachPanesthia angustipennis spadicaShiraki (Blaberidae) lives in a tunnel of decayed logs and is considered as gregarious species. However, decayed logs are distributed in a forest in clumps, and woody tunnels in decaying logs provide a semi‐enclosed environment for nymphs. We performed laboratory experiments to determine whether first‐ and second‐instar nymphs ofP. angustipennis spadicashow gregariousness in small spaces like woody tunnels. We also compared the aggregation intensity of sibling groups and mixed groups in the second instar. The laboratory experiments demonstrated that both the first‐ and second‐instar nymphs show gregariousness, with no difference in aggregation behavior regardless of kin relatedness. These results suggest that non‐kin‐based gregariousness may help to maintain colonies ofP. angustipennis spadicathat contain individuals derived from multiple families in a field.

Published: June 2021

AbstractThe clustering of big data streams has become a challenging task due to time and space constraints of the hardware and decreasing accuracy when the dimensionality of input data grows in time. In this paper, fuzzy growing neural gas is introduced, an online fuzzy approach for clustering data streams based on the growing neural gas algorithm, by adopting more restrictive criteria for selecting the winner nodes in the topological graph constructed at each iteration of the algorithm. The algorithm is tested on public datasets, and the results show improvements over existing clustering methods.

AbstractBackgroundThe incidence of end‐stage organ disease in people living with human immunodeficiency virus (HIV) (PLWH) is increasing, as people live longer due to potent, tolerable antiretroviral therapy (ART). Consequently, the number of PLWH who would benefit from solid organ transplant (SOT) is rising. The SOT experience in PLWH in Australia remains limited.AimTo retrospectively review the outcomes for SOT in PLWH at our service, in Victoria, Australia.MethodsA retrospective cohort study of PLWH undergoing SOT over a 15‐year period was performed. Adult PLWH age >18 years were eligible and identified from the Victorian HIV Service database. Descriptive statistics were used to summarise baseline demographics and clinical data, and outcomes following SOT.ResultsNine virologically suppressed PLWH underwent SOT from HIV‐negative donors (five kidneys, two livers and two bilateral sequential lung transplants). All patients were male, with a median age of 57.3 years (interquartile range (IQR) = 54.3–60.1) and CD4 count of 485 (IQR = 342–835) at transplantation, and comorbidities were common at baseline. After a median follow up of 3.9 years (IQR = 2.7–7.6), 8 (89%) patents were alive, 7 (78%) had functioning grafts, although 5 (56%) experienced organ rejection. Infections were common. Two patients required modification to their ART due to significant drug−drug interactions prior to transplant, while 5 (56%) had modifications post‐SOT. No patients experienced HIV virologic failure.ConclusionPLWH with end‐stage organ disease experience good clinical and functional outcomes and should be considered for SOT where indicated. However, multidisciplinary planning and care is essential to optimise care in this patient group.
Central sensitivity and fibromyalgia
Authors: Mezhov Veronica , Guymer Emma , Littlejohn Geoffrey 
Published: June 2021

AbstractFibromyalgia presents with symptoms of widespread pain, fatigue, sleeping and cognitive disturbances as well as other somatic symptoms. It often overlaps with other conditions termed ‘central sensitivity syndromes’, such as irritable bowel syndrome, chronic fatigue syndrome and temporomandibular disorder. Central sensitisation, mediated by amplified processing in the central nervous system, has been identified as the key pathogenic mechanism in these disorders. The term ‘central sensitivity’ can be used to describe collectively the clinical presentation of these disorders. Fibromyalgia is highly prevalent in most rheumatic diseases as well as non‐rheumatic chronic diseases and if unrecognised results in high morbidity. It is diagnosed clinically after excluding important differential diagnoses. Diagnostic criteria have been developed as tools to help identify and diagnose fibromyalgia. Such tools can fulfil an important need when managing patients with rheumatic disease and other chronic diseases as a way to identify fibromyalgia and improve patient outcomes. Treatment involves an integrated approach including education, exercise, stress reduction and pharmacological therapies targeting the central nervous system. This approach is suitable for all presentations of central sensitivity and some central sensitivity syndromes have additional treatment options specific to the clinical presentation.
Skin in the game: The professionalization of lived experience roles in mental health
Authors: Roennfeldt Helena , Byrne Louise 
Published: June 2021

AbstractThe lived experience workforce has moved from being a grassroots support and activist movement to become the fastest growing workforce within mental health. As lived experience work becomes assimilated within mainstream mental health service delivery, it faces mounting pressure to become more professionalized. Professionalization has evoked both optimism and fear, with diverging views within the lived experience workforce. In this paper, an assessment of the existing professionalization of the lived experience workforce is undertaken by drawing on theoretical positions and indices of what constitutes a profession. The arguments for and against professionalization are explored to identify the risks, benefits, and considerations for the lived experience workforce. The drive for professionalization has largely occurred due to the clinically focused mental health systems’ valuing of professional identity. The argument in favour of professionalization is motivated by a need for credibility within the views of that system, as well as greater regulation of the workforce. However, tensions are acknowledged with concerns that professionalization to appeal to the clinically focused system may lead to erosion of the values and uniqueness of lived experience work and nullify its effectiveness as an alternative and complementary role. Given mental health nurses are increasingly colleagues and often line managers of lived experience workers, it is important at this stage of lived experience workforce development that mental health nurses understand and are able to advocate for lived experience roles as a distinct professional discipline to help avoid the risks of co‐option to more dominant clinical practice.

AbstractSoybean production can be affected by heat (HS) and water stress (WS). However, studies on effects of stresses combination under field conditions are still scarce. The objective of this study was to evaluate the impact of HS, WS and their interaction (HS × WS) during seed filling on seed weight, seed growth rate (SGR) and seed filling duration (SFD) of same phenological age pods from different canopy positions. Two soybean genotypes were exposed to four treatments during seed filling: control (irrigated plots at ambient temperature), HS (plots under temperatures >32°C for 6 hr/day during 15 days), WS (plots under 25% of soil water content, during entire seed filling) and HS × WS. Stresses interaction caused similar responses to WS alone, decreasing yield and its components (seed number and weight), as well as seed weight for each canopy position (SWCP), SGR and SFD. Non‐significant effect of irrigated HS and non‐additive effects was observed in HS × WS plots, exhibiting WS a dominant effect over HS. The SWCP strongly correlated with SGR, exhibiting upper position a trend to higher SWCP than lower one. Seed maximum water content and pod weight, positively associated with SWCP, indicated seed metabolic limitations under WS and HS × WS. Our results advance in the understanding of SW determination under abiotic stresses and highlight the importance of identifying pods of same phenological age to establish accurate comparisons between seeds from different canopy positions.

Published: June 2021

AbstractThis work describes a physics‐based model to simulate the polymer infiltration and pyrolysis (PIP) manufacturing process for ceramic matrix composites (CMCs). Models have been developed to characterize volumetric distribution of constituents and track porosity inside the composite at different PIP stages utilizing test data from TGA and DSC characterization of a commercial preceramic polymer. Laboratory experiments were done using C/SiC CMC specimens manufactured with a variable number of PIP cycles in order to obtain inputs for the models, and the analytical results have been shown to agree with porosity determined from physical measurements.
Nonlinear dielectric response and positive dielectric tunability in antipolar CaTiSiO5
Authors: Murata Tomoki , Asaka Toru , Hirose Sakyo 
Published: June 2021

AbstractDielectric tunability has been extensively investigated in ferroelectric materials, which exhibit a negative tunability of dielectric permittivity in an external electric field. In contrast, positive tunability is rare and has been reported only in a few antiferroelectric materials. We present positive (and negative) tunability in the titanite, CaTiSiO5. The dielectric property of CaTiSiO5 was measured up to an extraordinarily high electric field of 40 MV/m. A nonlinear polarization field loop with no hysteresis was obtained. The dielectric permittivity of εr ~ 25 increases up to εr ~ 40 at 20 MV/m and room temperature. Although titanite has an antipolar structure and is expected to be “antiferroelectric,” its dielectric response in high electric fields up to ~40 MV/m differs from that of conventional antiferroelectrics. We demonstrate that the phase‐transition temperature and dielectric tunability could be modulated through the chemical substitution of Ca1−xLaxTiSi1−xAlxO5, in which the destabilization of the long‐range antipolar order is revealed by transmission electron microscopy analysis. These results indicate that the observed dielectric response to an electric field may originate from the unique features of the antipolar and domain structures in CaTiSiO5.

AbstractAimsThis study examined the nature and characteristics of Black women's interactions with medical providers during childbirth when accompanied by a perinatal support professional (PSP; similar to a doula).DesignThe design was qualitative, and a phenomenological approach was employed to examine the meaning of women's experiences.MethodsWe conducted in‐depth interviews with 25 Black women enrolled in a perinatal support program in Cleveland, Ohio, in late 2017 and early 2018, exploring their interactions with medical providers, the meaning of their experiences, and the roles their PSPs played.ResultsClients broadly categorized experiences as positive or negative. When medical providers respected them, their birth plans and/or collaborated with PSPs, women reported more positive experiences. They associated negative experiences with providers having their own timelines and agendas, and women perceiving their needs were unheard and/or disrespected.ConclusionThe findings emphasize the need for medical providers to be patient‐centred, set aside assumptions, treat their patients as experts, value women's knowledge and voice, and treat patients and their supports as part of the team.ImpactFindings support the importance of having a knowledgeable but non‐medical support person present during birth. We discuss implications for how empowerment may be a tool to achieving better birth outcomes.

AbstractHomocysteine is an independent risk factor for cardiovascular and cerebrovascular disease and has been proposed to contribute to vascular dysfunction. We sought to determine in a real‐world clinical setting whether homocysteine levels were associated with hypertension mediated organ damage (HMOD) and could guide treatment choices in hypertension. We performed a cross‐sectional analysis of prospectively collected data in 145 hypertensive patients referred to our tertiary hypertension clinic at Royal Perth Hospital and analyzed the association of homocysteine with HMOD, renin‐angiotensin‐aldosterone system (RAAS), and RAAS blockade. The average age of participants was 56 ± 17 years, and there was a greater proportion of males than females (89 vs. 56). Regression analysis showed that homocysteine was significantly associated with PWV (β = 1.99; 95% CI 0.99‐3.0; p < .001), albumin‐creatinine ratio (lnACR: β = 1.14; 95% CI 0.47, 1.8; p < .001), 24 h urinary protein excretion (β = 0.7; 95% CI 0.48, 0.92; p < .001), and estimated glomerular filtration rate (β = −29.4; 95% CI −36.35, −22.4; p < .001), which persisted after adjusting for potential confounders such as age, sex, 24 h BP, inflammation, smoking, diabetes mellitus (DM), and dyslipidemia. A positive predictive relationship was observed between plasma homocysteine levels and PWV, with every 1.0 µmol/L increase in homocysteine associated with a 0.1 m/s increase in PWV. Homocysteine was significantly associated with elevated aldosterone concentration (β = 0.26; p < .001), and with attenuation of ACEi mediated systolic BP lowering and regression of HMOD compared to angiotensin receptor blockers in higher physiological ranges of homocysteine. Our results indicate that homocysteine is associated with hypertension mediated vascular damage and could potentially serve to guide first‐line antihypertensive therapy.

AbstractThe coronavirus disease 2019 (COVID‐19), caused by the novel severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2), has resulted in many deaths throughout the world. It is vital to identify the novel prognostic biomarkers and therapeutic targets to assist with the subsequent diagnosis and treatment plan to mitigate the expansion of COVID‐19. Since angiotensin‐converting enzyme 2 (ACE2)‐positive cells are hosts for COVID‐19, we focussed on this cell type to explore the underlying mechanisms of COVID‐19. In this study, we identified that ACE2‐positive cells from the bronchoalveolar lavage fluid (BALF) of patients with COVID‐19 belong to bronchial epithelial cells. Comparing with patients of COVID‐19 showing severe symptoms, the antigen processing and presentation pathway was increased and 12 typical genes, HLA‐DRB5, HLA‐DRB1, CD74, HLA‐DRA, HLA‐DPA1, HLA‐DQA1, HSP90AA1, HSP90AB1, HLA‐DPB1, HLA‐DQB1, HLA‐DQA2, and HLA‐DMA, particularly HLA‐DPB1, were obviously up‐regulated in ACE2‐positive bronchial epithelial cells of patients with mild disease. We further discovered SDCBP was positively correlated with above 12 genes particularly with HLA‐DPB1 in ACE2‐positive bronchial epithelial cells of COVID‐19 patients. Moreover, SDCBP may increase the immune infiltration of B cells, CD8+ T cells, CD4+ T cells, macrophages, neutrophils and dendritic cells in different lung carcinoma. Moreover, we found the expression of SDCBP was positively correlated with the expression of antigen processing and presentation genes in post‐mortem lung biopsies tissues, which is consistent with previous discoveries. These results suggest that SDCBP has good potential to be further developed as a novel diagnostic and therapeutic target in the treatment of COVID‐19.
Old Wine in New Bottles? The European Union's Organizational Response to Reforming EU–African Migration Cooperation
Authors: Mouthaan Melissa 
Published: June 2021

AbstractIn 2015, the European Commission responded to renewed demands from its political environment to achieve more results in its external relations with African countries in migration. This article explores how calls for action from domestic arenas formed an adaptation pressure on the EU's external migration governance, and first examines the implications of this for political cooperation and instrumentation. In assessing adaptation in these areas, this article addresses the question of whether a fundamental redefinition of the EU's engagement with African states has occurred. Secondly, the article proposes that mal‐integration of policy emerges as an organizational compromise that allows a number of functional interests to be met. It allows for the broad enlisting of support from different parts of the administration; it enables the performance of a response to demands that cannot be realistically met; and allows a reconciling of different interests under one approach.
The politics of the surgical mask: Challenging the biomedical episteme during a pandemic
Authors: Neilson Shane 
Published: June 2021

AbstractCOVID‐19 has seen politicians use a selective ‘science’ to justify restrictions on mobility and association, to mandate the wearing of face masks, and to close public infrastructure. There seems to be no role for health humanities scholars as yet, but perhaps there should be. This paper considers the fate of a health humanities article on surgical mask use that was published in a biomedical journal in 2016. This article, which did not operate from within the biomedical episteme but which was in conversation with the episteme, was misappropriated on both sides of the political spectrum to justify personal beliefs around mask use in the pandemic. This mistaken misappropriation is not only evidence of the utility of the common ground shared between biomedicine and the health humanities, it is also evidence of the possibilities inherent in a future interdisciplinary involving biomedicine and the health humanities.

Published: June 2021

AbstractThis work investigates important heat and mass transfer parameters of a variety of paddy named Fajr, during a thin layer convective drying. The experiments on drying are conducted at air temperatures in the domain of 30–80°C with air velocities between 0.54 and 3.27 m s−1. Mathematical equations are developed to adjust the experimental data obtained for the thin layer drying. The drying results show that the Henderson and Pabis' model satisfactorily fit all the experimental data for the convective drying behavior of paddy. The effective diffusivity of moisture transfer, calculated by the Fick's second law of diffusion, varies from 1.109 × 10−11 to 5.858 × 10−10 m2 s−1 and the highest values of the Dincer, Biot, Reynolds, and Nusselt numbers obtained are 2.383 × 105; 0.2026; 1.833 × 107; and 8,434, respectively. The obtained results demonstrate that the coefficient of mass transfer (hm) for paddy lies between 5.118 × 10−8 and 4.807 × 10−6 m s−1, while the heat transfer coefficient (hc) ranges from 811 to 2,474 W m−2 K−1. Furthermore, the values of the energies of activation obtained for moisture diffusion (Ed) and convective mass transfer (Ec) are in the range of 50.538–61.825 kJ mol−1 and 72.325–87.386 kJ mol−1, respectively. Therefore, knowledge regarding to the determination process of heat and mass transfer characteristics can help to distinguish the suitable operating conditions for saving the maximum value of energy.Practical ApplicationsSome grains have a short shelf life that limits their commercialization as fresh products and increase postharvest losses. Drying is an interesting alternative to the development of new products of grains like paddy with added value. This research work involved the estimation of heat and mass transfer properties during convective drying by using two calculation methodologies, allowing estimating the diffusivity and the mass and heat transfer coefficients for paddy. Also, the activation energy for moisture diffusion and for convective mass transfer was determined, assuming that the temperature dependence of the diffusion coefficient and the mass transfer coefficient follows an Arrhenius type relationship. Therefore, also the study presents a simple method to greatly enhance the shelf life of wet paddy by convective drying and it can be applied for the better preservation of this product.
