Authors: Zhang Mingkang , Xu Meizhen , Li Jinwei , Shi Wenqing , Chen Yangzhi 
Published: September 2022

Purpose
This study aims to explore the compressive behavior of hollow triply periodic minimal surface (HTPMS) cellular structures by selective laser melting (SLM).

Design/methodology/approach
This study presents a design method for gyroid hollow triply periodic minimal surfaces (G-HTPMS) and primitive hollow triply periodic minimal surfaces (P-HTPMS) cellular structures, and SLM technology was applied to manufacture these cellular structures. Compressive behaviors and energy absorption behaviors of hollow cellular structures were researched in this study.

Findings
Compared with normal gyroid triply periodic minimal surfaces (G-TPMS) and normal primitive triply periodic minimal surfaces (P-TPMS), the G-HTPMS and P-HTPMS have higher elastic modulus, plateau stress and effective energy absorption under uniaxial compression. The hollow design in HTPMS can enhance the mechanical properties and energy absorption of the cellular structure. Finite element analysis also demonstrates that the hollow design can reduce stress concentration, which improved the compressive curves from a severely fluctuating state to a relatively flat state and reduces fracture. According to compressive behaviors, G-TPMS and G-HTPMS are the bending-dominated cellular structures with strain hardening characteristics, and P-TPMS and P-HTPMS are the stretching-dominated cellular structures with strain softening characteristics.

Originality/value
This research provided a design method for HTPMS, and it was proved that the mechanical properties increased by hollow design inspired by bamboo.
Exchange rate volatility and trade flows in Indonesia and ten main trade partners: asymmetric effects
Authors: Heriqbaldi Unggul , Esquivias Miguel Angel , Handoyo Rossanto Dwi , Rifami Alfira Cahyaning , Rohmawati Hilda 
Published: September 2022

Purpose
This paper aims to examine whether Indonesian cross-border trade responds asymmetrically to exchange rate volatility (ERV).

Design/methodology/approach
An exponential generalized autorgressive conditional heteroscedasticity model is applied to estimate the ERV of Indonesia and ten main trade partners using quarterly data from 2006 to 2020. A nonlinear autoregressive distributed lag estimation is applied to estimate the impact of ERV on cross-border trade. Impacts from the global financial crisis (GFC) of 2008 and the COVID-19 pandemic are covered. Dynamic panel data is used for the robustness test.

Findings
In the short-run, ERV significantly affects exports to most of the top partners (positively, negatively or both). In the long run, asymmetric effects occur in Indonesia’s exports to five top destinations. The weakening of the Indonesian Rupiah mainly supports exports in the short term. Imports from top partners are also affected by ERV in both the short run and, to a lesser extent, in the long run. Both the GFC and the COVID-19 pandemic reduced trade: for most cases, in the short run. The dynamic panel model suggests that ERV has asymmetric impact on cross-border trade in the long run.

Practical implications
Exchange rate strategies need to avoid a single-side policy approach and, instead, account for exporter and importer differences in risk behaviour and an asymmetric response to ERV in trade. Policymakers need to consider policies that stabilise the currency.

Originality/value
This study provides evidence that cross-border trade can react asymmetrically to the exchange rate uncertainty and that the impacts of real ERV are asymmetric as well. The authors also apply a dynamic panel that signals that ERV matters in the long run for Indonesian trade with top partners.
Elastic wave velocities in a granitic geothermal reservoir
Authors: Sayers Colin M. 
Published: September 2022

AbstractGeothermal resources have potential for providing cost‐effective and sustainable energy. Monitoring of production‐induced changes in geothermal reservoirs using seismic waves requires understanding of the elastic properties of the rock and how they change due to injection of fluids and opening and closing of natural and hydraulic fractures. P‐ and S‐wave velocities measured in a granitic geothermal reservoir using sonic logging are systematically lower than those predicted using the composition of the rock. Cracks may occur in granitic rocks from tectonic stresses and from the thermal expansion mismatch between differently oriented anisotropic crystals. An isotropic orientation distribution of microcracks causes a significant reduction in both the P‐ and S‐velocities, consistent with the observed sonic P‐ and S‐velocities. Vertical fractures cause a difference in the velocity of vertically propagating shear waves polarized parallel and perpendicular to the fractures. An assumption that the lower measured velocities are caused by the presence of vertical fractures is inconsistent with the sonic data. This is because vertical fractures cause a decrease in slow S‐wave velocity that greatly exceeds the decrease in P‐wave velocity, in contrast to the observed data. The growth of vertical fractures in the geothermal reservoir may be monitored using the difference in velocity of the fast and slow shear waves, while the change in P‐velocity in a crossplot of measured P‐ and slow S‐velocities is useful for estimating the ratio of the normal‐to‐shear compliance of the fractures.
Group heterogeneity and the economic effect of farmer organisation participation: Empirical evidence from Taiwan
Authors: Tsai Min‐Han , Luh Yir‐Hueih 
Published: September 2022

AbstractWe explore the effects of different farmer organisations on smallholder farmers' economic performance. The average treatment effect of switching between different farmer organisations is examined. In addition, based on the premise that a higher level of social capital is accumulated through participation in multiple farmer organisations, we also investigate how the economic consequences of farmer organisation membership vary with the intensity of participation. Our conceptual model explicitly includes social capital to provide a micro‐foundation and a theoretical justification for the linkage between farmer organisation participation and the economic outcome. This indicates that participating in different types of farmer organisations is beneficial for farm households only when the returns from social capital investment outweigh the time cost of participation. Our empirical results suggest that membership of farmer organisations that are more homogeneous in terms of member specialty and similarity in production and marketing activities results in a significant increase in farm sales revenue and net returns. This result supports the view that technological proximity accentuates knowledge spillovers within the farmer organisations, and thus leads to better economic outcomes. In line with the prediction of the theoretical model, the average treatment effect of participation is found to increase with the number of organisations that farmers belong to. Moreover, results from the quantile regression provide empirical evidence supporting increasing returns to social capital accumulated through participation in several farmer organisations.
Mistakes in terminology cause false conclusions: Vitamin D does not increase the risk of dementia
Authors: Vieth Reinhold 
Published: September 2022

AbstractThere has been a progressive trend in recent years, to trivialize the terminology surrounding the molecules based on a secosteroid structure. The generic use of the term, “vitamin D," results in gross misrepresentations that confuse the use of a drug commonly used for patients with kidney failure, with the nutritional use of vitamin D. This commentary is a critique of one particularly bad example of that terminological trivialization. Authors may simply want to add impact to their findings when they refer to “vitamin D supplementation” when what they are reporting on is calcitriol. However, the consequences of this practice are to mislead all readers who do not go through the primary publication very carefully to understand the details behind sloppy terminology. Contrary to all the words written in the publication commented upon here, it offers no clinical evidence that vitamin D supplementation increases risk of Alzheimer's disease or dementia.
Racial and ethnic differences in diet quality and food insecurity among adults with fatty liver and significant fibrosis: a U.S. population‐based study
Authors: Kardashian Ani , Dodge Jennifer L. , Terrault Norah A. 
Published: September 2022

SummaryBackgroundFood insecurity affects diet quality (DQ) and is associated with non‐alcoholic fatty liver disease (NAFLD). While racial and ethnic disparities in NAFLD exist, the relationship between food insecurity and DQ by race and ethnicity is unknown.AimTo examine the relationship between food insecurity and DQ in adults with NAFLD and significant fibrosis by race and ethnicity in a nationally representative cohortMethodsWe performed a cross‐sectional analysis of U.S. adults (≥20 years) in the National Health and Nutrition Examination Survey 2017–2018 with vibration‐controlled transient elastography (VCTE), DQ, and food security (FS) measurements. NAFLD and significant fibrosis were defined using validated VCTE cut‐offs. We assessed total and component DQ by the healthy eating index (HEI)‐2015, with poor scores defined as <25th percentile. We used multivariable linear and logistic regression to examine associations of FS and race/ethnicity with DQ.ResultsOf 1351 adults with NAFLD (17% food insecure; 248 with fibrosis), mean (standard error [SE]) DQ score was 49 (1) and 47(1.2) for food secure and insecure groups, respectively. Mean (SE) DQ was lowest for White (47[1.1]), followed by Black (49[0.9]), Hispanic (50[1.2]) and Asian persons (56[2.1]). In multivariable models, there was an inverse relationship between FS and DQ, although this did not reach statistical significance (estimated difference [coef]:‐1.8 mean HEI score, 95% CI: −4.3–0.7; p = 0.14). Adjusted mean DQ scores were higher for Black (coef:+3.0, 95% CI:0.5–5.5; p = 0.02), Asian (coef:+7.4, 95% CI:3.4–11.5; p = 0.001) and Hispanic (coef: +4.3, 95% CI: 0.6–7.9; p = 0.03) compared to White persons. Greatest differences in DQ components by food security status were seen in White persons.ConclusionAmong adults with NAFLD, White persons had poorer DQ than other races/ethnicities. The influence of food insecurity on DQ may be potentiated in this group. Exploration of the sociocultural factors influencing DQ is needed to mitigate NAFLD disparities.
Trends in characteristics, management, and outcomes of patients presenting with gastrointestinal bleeding to emergency departments in the United States from 2006 to 2019

Published: September 2022

SummaryBackgroundRecent epidemiologic studies of trends in gastrointestinal bleeding (GIB) provided results through 2014 or earlier and assessed only hospitalised patients, excluding patients presenting to emergency departments (EDs) who are not hospitalised.AimsTo provide the first U.S. nationwide epidemiological evaluation of all patients presenting to EDs with GIBMethodsWe used the Nationwide Emergency Department Sample for 2006–2019 to calculate yearly projected incidence of patients presenting to EDs with primary diagnoses of GIB, categorised by location and aetiology. Outcomes were assessed with multivariable analyses.ResultsThe age/sex‐adjusted incidence for GIB increased from 378.4 to 397.5/100,000 population from 2006 to 2019. Upper gastrointestinal bleeding (UGIB) incidence decreased from 2006 to 2014 (112.3–94.4/100,000) before increasing to 116.2/100,000 by 2019. Lower gastrointestinal bleeding (LGIB) incidence increased from 2006 to 2015 (146.0 to 161.0/100,000) before declining to 150.2/100,000 by 2019. The proportion of cases with one or more comorbidities increased from 27.4% to 35.9% from 2006 to 2019. Multivariable analyses comparing 2019 to 2006 showed increases in ED discharges (odds ratio [OR] = 1.45; 95% confidence interval [CI] = 1.43–1.48) and decreases in red blood cell (RBC) transfusions (OR = 0.62; 0.61–0.63), endoscopies (OR = 0.60; 0.59–0.61), death (OR = 0.51; 0.48–0.54) and length of stay (relative ratio [RR] = 0.81; 0.80–0.82). Inpatient cost decreased from 2012 to 2019 (RR = 0.92; 0.91–0.93).ConclusionsThe incidence of GIB in the U.S. is increasing. UGIB incidence has been increasing since 2014 while LGIB incidence has been decreasing since 2015. Despite a more comorbid population in 2019, case fatality rate, length of stay and costs have decreased. More patients are discharged from the ED and the rate of RBC transfusions has decreased, possibly reflecting changing clinical practice in response to updated guidelines.

SummaryConstitutional thrombocytopenias are rare disorders, often difficult to discriminate from acquired thrombocytopenias. More than 80 genes have been described as being at the origin of these diseases. Among them, several variants of the glycoprotein Ib platelet subunit alpha (GP1BA) and glycoprotein Ib platelet subunit beta (GP1BB) genes, coding for the GpIb‐IX‐V glycoprotein complex, have been reported in the literature. The study reported here aimed at describing newly identified monoallelic anomalies affecting the GP1BA and GP1BB genes on a clinical, biological and molecular level. In a cohort of nine patients with macrothrombocytopenia, eight heterozygous variants of the GP1BA or GP1BB genes were identified. Five of them had never been described in the heterozygous state. Computer modelling disclosed structure/function relationships of these five variants.
Nowhere Else but Home: A National Resting Place for Indigenous Australian Ancestral Remains
Authors: Norman Heidi , Payne Anne Maree 
Published: September 2022

AbstractThis article addresses the establishment of the National Resting Place, a new Australian cultural institution designed to perform a vital role in the care of Ancestral Remains. Exploring the history of why there are, and have been, many thousands of Ancestral Remains in Australia that need to be repatriated, reburied or cared for as a community determines, this article demonstrates the physical and cultural harm caused to Indigenous people through the cultural and professional practices of scientists, anatomists, and collectors throughout the main era of collecting, highlighting how the methods and norms of collecting in this era led to a lack of provenance and other identifying information for many Ancestral Remains. The article identifies the challenges of repatriation in the Australian context and discusses the emergence of a new model, the National Resting Place, to provide an Indigenous‐centred response to the care of Ancestral Remains in Australia.
The effect of forming implementation intentions on alcohol consumption: A systematic review and meta‐analysis
Authors: Cooke Richard , McEwan Helen , Norman Paul 
Published: September 2022

AbstractIssuesMeta‐analysis was used to estimate the effect of forming implementation intentions (i.e., if‐then plans) on weekly alcohol consumption and heavy episodic drinking (HED). Sample type, mode of delivery, intervention format and timeframe were tested as moderator variables.ApproachCochrane, EThOS, Google Scholar, PsychArticles, PubMed and Web of Science were searched for relevant publications to 31 March 2021. Random‐effects meta‐analysis was used to estimate the effect size difference (d) between individuals forming versus not forming implementation intentions on weekly consumption and HED.Key FindingsSixteen studies were included in meta‐analyses. The effect size difference for forming implementation intentions on weekly alcohol consumption was d+ = −0.14 confidence interval (CI) [−0.24; −0.03]. Moderator analyses highlighted stronger effects for: (i) community (d+ = −0.38, CI [−0.58; −0.18]) versus university (d+ = −0.04, CI [−0.13; 0.05]) samples; (ii) paper (d+ = −0.26, CI [−0.43; −0.09]) versus online (d+ = −0.04, CI [−0.14; 0.06]) mode of delivery; and (iii) volitional help sheet (d+ = −0.34, CI [−0.60; −0.07]) versus implementation intention format (d+ = −0.07, CI [−0.16; 0.02]). In addition, effects diminished over time (B = 0.02, SE = 0.01, CI [0.03; 0.01]). Forming implementation intentions had a null effect on HED, d+ = −0.01 CI [−0.10; 0.08].ImplicationsForming implementation intentions reduces weekly consumption but has no effect on HED.ConclusionThis review identifies boundary conditions on the effectiveness of implementation intentions to reduce alcohol consumption. Future research should focus on increasing the effectiveness of online‐delivered interventions and integrating implementation intention and motivational interventions.

AbstractThe latest advancements in Internet of Things (IoT) have revolutionized the productivity of global shipping industry in the recent years. It also led to the emergence of IoT‐enabled Maritime Transportation Systems (MTS). These approaches detect the malware in network before the execution process. Various machine learning (ML) models have been proposed and designed in literature for effective malware detection. However, the existence of numerous features in the data bring dimensionality problem which can be only resolved by the use of feature selection approaches. Therefore, the current research work presents Intelligent Metaheuristics‐based Feature Selection model with Optimal ML approach for Malware Detection (IMFSOML‐MD) on IoT‐enabled MTS. Primarily, IMFSOML‐MD technique involves the design of Quantum Invasive Weed Optimization Algorithm‐based Feature Selection technique to optimally choose a subset of features. Moreover, an Optimal Wavelet Neural Network (OWNN) model is employed to perform classification process. The initial parameters of WNN model are optimally tuned with the help of Colliding Bodies Optimization algorithm thereby improving the detection performance. The proposed IMFSOML‐MD technique was experimentally validated using publicly‐available CICMalDroid2020 dataset. The results from extensive comparative analysis demonstrated the superiority of the proposed IMFSOML‐MD technique over other compared methods in terms of detection performance with maximum accuracy of 98.96%.
Ocean acidification drives global reshuffling of ecological communities
Authors: Nagelkerken Ivan , Connell Sean D. 
Published: September 2022

AbstractThe paradigm that climate change will alter global marine biodiversity is one of the most widely accepted. Yet, its predictions remain difficult to test because laboratory systems are inadequate at incorporating ecological complexity, and common biodiversity metrics have varying sensitivity to detect change. Here, we test for the prevalence of global responses in biodiversity and community‐level change to future climate (acidification and warming) from studies at volcanic CO2 vents across four major global coastal ecosystems and studies in laboratory mesocosms. We detected globally replicable patterns of species replacements and community reshuffling under ocean acidification in major natural ecosystems, yet species diversity and other common biodiversity metrics were often insensitive to detect such community change, even under significant habitat loss. Where there was a lack of consistent patterns of biodiversity change, these were a function of similar numbers of studies observing negative versus positive species responses to climate stress. Laboratory studies showed weaker sensitivity to detect species replacements and community reshuffling in general. We conclude that common biodiversity metrics can be insensitive in revealing the anticipated effects of climate stress on biodiversity—even under significant biogenic habitat loss—and can mask widespread reshuffling of ecological communities in a future ocean. Although the influence of ocean acidification on community restructuring can be less evident than species loss, such changes can drive the dynamics of ecosystem stability or their functional change. Importantly, species identity matters, representing a substantial influence of future oceans.
Mechanical integrity of ceramic coatings on Kapton made by a dry aerosol deposition of lunar mare simulant
Authors: Calvo Robert , Fuierer Paul 
Published: September 2022

AbstractThe purpose of this paper is to demonstrate the use of lunar regolith and the dry aerosol deposition (DAD) method to produce ceramic coatings on polyimide polymer, and to test their mechanical integrity. Ceramic films were produced on Kapton substrates using a custom‐built DAD system and lunar mare simulant (LMS) feedstock. Ultrafine grains and impact densification were confirmed using atomic force and electron microscopy. Mechanical properties of the DAD–LMS Kapton samples were evaluated with indentation, tensile, and mandrel bend tests. DAD–LMS coatings tripled the hardness and doubled the indentation modulus of the Kapton surface. Coatings 3–16 µm thick did not have a predictable effect on the ultimate tensile strength or elongation to failure; however, the apparent modulus of elasticity did increase. The coatings were able to withstand significant bending before damage, with critical bend radii of 5 and 1.5 mm for 7.5 µm and 120 nm thicknesses, respectively. Modest heat treatment was shown to reduce the bending strain of coated substrates. Advanced ceramic coatings are of interest for the protection of space and satellite polymers from micrometeoroid impacts, radiation, and atomic oxygen. Lunar posts and habitats will require the development of space manufacturing techniques and in situ resource utilization.
