Failure analysis of spar buoy floating offshore wind turbine systems
Authors: Shafiee Mahmood 
Published: November 2022

AbstractFloating offshore wind energy is a new form of marine renewable energy which is attracting a great deal of attention worldwide. However, the concepts of floating offshore wind turbines (FOWTs) are still in early stages of development and their failure properties are not yet fully understood. Compared to bottom-fixed wind turbines, FOWTs are subject to more extreme environmental conditions and significant mechanical stresses which may cause a higher degradation rate and shorter mean-time-to-failure for components/structures. To fill the research gap, this paper aims to conduct qualitative and quantitative failure studies on an OC3 spar-type FOWT platform with 3 catenary mooring lines. The failure analyses are performed based on two well-established reliability engineering methodologies, namely, fault tree analysis (FTA) and failure mode and effects analysis (FMEA). The most critical FOWT components are prioritized according to their failure likelihood as well as the risk-priority-number. Our results show a good agreement between the two methods with regard to failure criticality rankings. However, some differences between the results are also observed that are attributed to the difference between FTA and FMEA methodologies as the former incorporates the causes of various failure modes into analysis, whereas the latter is mainly adopted for a single random failure analysis. The results obtained from the FMEA study for the FOWT system will also be compared with those reported for bottom-fixed offshore wind turbines and some interesting conclusions are derived.

Published: November 2022

AbstractIn this study, an improved cepstrum-convolutional neural network is proposed, which can solve the problem of low recognition accuracy of 1-s short utterance in speaker recognition technology. The audio feature Mel frequency cepstrum coefficient is extracted by using the improved cepstrum algorithm and the data of the two-dimensional acoustic feature vector matrix is preprocessed to convert the two-dimensional feature matrix into a three-dimensional tensor as the input data of the two-dimensional convolutional neural network model. Experiments are carried out on an Arabic digital English pronunciation dataset with an audio duration of less than one second in a specific experimental environment. Moreover, the performance of this model is evaluated by accuracy and F1-score. The simulation results show that the accuracy of our proposed model for speech recognition is as high as 100% and 99.60% on the training and test sets, respectively, as well as the F1- score, is 0.9985. It can be seen that the recognition method of this model solves the problem of accuracy degradation of short utterance speaker recognition due to the short duration of the corpus and improves the accuracy of short speech voice recognition. The model is simple but effective, generalization, superior, and has higher practical application value.Article Highlights.

It is interesting to study how to improve the accuracy of 1-s short utterance speaker recognition.

The improved cepstrum algorithm can solve the problem of not extracting enough discernible acoustic features.

This paper proposed model obtained 100% accuracy on a spoken Arabic digit dataset with an audio duration about 0.3 s.

AbstractSustainable urban development is a key compoment in the United Nation’s Sustainable Development Goals. Monitoring urbanization is critical for planners, governments and non-governmental organizations, and scientists to design policies that maximize the use of natural resources and accommodate development while reducing environmental effects. This research aims to analyze how urbanization patterns have changed in the largely unknown least developed regions of Bangladesh. Multispectral satellite imageries over 30 years (1991 to 2021) were used to analyze the urbanization pattern of Jamapur district. Utilizing object-based image classification and on-field validation for seven Land Use and Land Cover classes, it was found that built-up area expanded by 748.92% during the past three decades while depleting bare soil (− 97.65%), deep waterbody (− 79.33%), shallow waterbody (− 8.46%), light vegetation (− 14.28%) and agricultural land (− 26.33%).. Because of increased in built-ups, the land surface temperatures (LST) were also increased over the study period (the minimun recorded LST were 12.84 °C, 15.89 °C, 15.8 °C and 17 °C while the maximun LST were 17.93 °C, 23.7 °C, 23.79 °C and 26.73 °C for the year of 1991, 2001, 2013 and 2021 respectively). This study will act as a baseline for future studies It be insightful to urban planners and policymakers in developing countries regarding urban sustainability and minimizing urban risks and hazards in the least developed districts.
Research on pricing and recycling decision of closed-loop supply chain under the mergers and acquisitions between competing manufacturers
Authors: Wang Jingjing , Deng Yaling , Wang Jun 
Published: November 2022

AbstractBased on the increasingly popular practice background of corporate mergers and acquisitions (M&A), the feasibility of M&A strategy is studied in the closed-loop supply chain (CLSC) in combination with the different financial strength of competing manufacturers. By constructing a game model in CLSC under three modes of the decentralized decision-making with well-capitalized manufacturers, the decentralized decision-making with a capital-constrained manufacturers and the M&A between competing manufacturers, the paper analyzes the influence of bank loan interest rate and M&A coefficient on the optimal decision and revenue to calculate the conditions that competing manufacturers need to meet to implement the M&A strategy. It finds that: firstly, with the increase of bank loan interest rate, the capital-constrained manufacturers will increase the wholesale price to obtain higher returns, and meanwhile reduce the recycling rate of old products to reduce the capital investment, but the well-capitalized manufacturers will also lower wholesale prices, but they will increase the recycling rate of old products to reduce production costs. Secondly, with the increase in bank interest rates, the revenue of capital-constrained manufacturers decreases, while the well-capitalized manufacturers increase. Thirdly, when competing manufacturers can increase market power or improve core production technology to reduce costs after mergers and acquisitions, they will increase the recycling of old products and reduce the wholesale price of products to gain more market share. Moreover, the better performance of the M&A strategy, the higher the benefits of closed-loop supply chain members will be. Finally, whether manufacturers are capital constrained or not, the M&A strategy are not always beneficial to the manufacturers. And whether the M&A strategy is beneficial or not is related to market demand parameters, recovery cost parameters and merger coefficient. But when these parameters meet certain conditions, the competitive manufacturer’s M&A strategy can benefit all members of the closed-loop supply chain.
Birnessite MnO2 supported on CNTs in-situ for low-temperature oxidation of ethyl acetate
Authors: Zeng Yongjian , Yang Xixian , Yu Hao 
Published: November 2022

AbstractThe removal of ethyl acetate has received much attention because excessive emissions of ethyl acetate are harmful to the environment and human health. Efficiently removing ethyl acetate under high space velocity requires low-cost catalysts operating at low temperatures. Herein, carbon nanotubes (CNTs) supported birnessite MnO2 catalysts were in-situ prepared by the redox reaction between KMnO4 and CNTs to maximize the interaction between MnO2 and support. The good thermal stability derived from the intact CNTs structure was important for the interaction between MnO2 and CNTs, contributing to the enhanced catalytic activity for ethyl acetate oxidation. 4MnO2-CNTs showed outstanding performance for the catalytic oxidation of ethyl acetate (100 ppm), achieving 100% removal efficiency and 99% CO2 selectivity at 160 °C under 100,000 mL·g−1·h−1 space velocity. In addition, 4MnO2-CNTs exhibited an excellent catalytic stability during the 50 h test period. Based on the comprehensive characterization study, we revealed that the activity of 4MnO2-CNTs could be effectively enhanced by the higher amount of active sites (Mn3+ and surface active adsorbed hydroxyl oxygen), as well as the strong interaction between MnO2 and support and the good thermal stability derived from the introduction of the intact CNTs structure.
The Symbolic Safeguard: Royal Absence in Cambodia’s Constitutional Monarchy
Authors: Lawrence Ben 
Published: November 2022

AbstractThe product of an internationalized peace process, Cambodia’s 1993 Constitution restored the monarchy and endowed the Crown with a political safeguarding role that successive kings have been unable to fulfil in practice. After a brief survey of the tragic modern history of Cambodia’s monarchy, this paper outlines the formal constitutional role of the king, highlighting the central dichotomy between the provisions that promise that the king “shall reign but shall not govern” and those that provide the king a more active role as “guarantor.” The paper highlights how this fundamental ambiguity has been borne-out publicly, by focusing on a handful of specific instances in which both King Sihanouk and King Sihamoni are understood to have been strategically absent from the country to avoid signing controversial legislation. Short of providing a veto power in the legislative process, the king’s safeguarding role is shown to manifest in the symbolic denial of royal legitimacy.
Is the Capabilities Approach operationalizable to analyse the impact of digital identity on human lives
Authors: Marsman Henk 
Published: November 2022

Abstract
Digital identity systems are promoted with the promise of great benefit and inclusion. The case of the Ugandan digital identity system demonstrates that the impact of digital identity systems is not only positive but also has negative impacts, significantly affecting human lives for the worse. The impact on the human lives of digital identity systems can be assessed by multiple frameworks. A specific framework that has been mentioned is the capabilities approach (CA). This article demonstrates that the CA is a framework to assess the impact on human lives that can be operationalized for technology and information and communication technology, including digital identity systems. Further research is required to compare the CA with other candidate evaluation frameworks.

AbstractZinc deficiency (ZD) during pregnancy has far-reaching consequences on the mother, fetus and subsequent child survival. Therefore, the present study aimed to assess the prevalence and associated factors of ZD among pregnant women around Lake Awasa, Hawassa City, Ethiopia. To this end, a facility-based cross-sectional study was conducted on 333 randomly sampled pregnant women from 08 April to 08 May 2021. The socio-economic, dietary intake, water, sanitation and hygiene, obstetric, and maternal health data were collected through face-to-face interviews. Moreover, on-spot blood and stool samples were taken. Descriptive statistics and binary and multivariable logistic regression analysis were conducted. The prevalence of ZD was 58⋅6 % (95 % CI 53⋅31, 63⋅89). The poorest (AOR = 3⋅28; 95 % CI 1⋅26, 8⋅50) and poor (AOR = 2⋅93; 95 % CI 1⋅14, 7⋅54) wealth quintiles, four of more family size (AOR = 1⋅84, 95 % CI 1⋅10, 3⋅35), poor dietary diversity (AOR = 4⋅11; 95 % CI 2⋅11, 7⋅62), not eating snacks (AOR = 3⋅40; 95 % CI 1⋅42, 8⋅15), not consuming fish (AOR = 3⋅53; 95 % CI 1⋅65, 7⋅56) and chicken (AOR = 2⋅53; 95 % CI 1⋅31, 4⋅88) at least once a month, and intestinal parasitic infection (AOR = 2⋅78; 95 % CI 1⋅52, 5⋅08) predicted zinc deficiency. In conclusion, ZD is a public health problem among pregnant women around Lake Awasa. The present study demonstrated that poor socio-economic status, large family size, poor nutritional practices and intestinal parasitic infection determine the zinc status in the present study area. The findings suggest the need for further analysis to deepen the understanding about ZD and consideration of livelihood in interventions to prevent and control ZD among pregnant women in Hawassa City, Ethiopia.
Dangerous Friendships in Eighteenth-Century Buddhist Laṅkā and Siam
Authors: Lehrer Tyler A. 
Published: November 2022

AbstractThe kingdoms of Kandy (now Sri Lanka) and Ayutthaya (now Thailand) were briefly connected across Indian Ocean waters in the mid-eighteenth century by Dutch East India Company (hereafter VOC) traders, leading to the importation of valuable Siamese Buddhist monks and their ordination lineage to the island. Two series of events related to the VOC's search for and delivery of these monks demonstrate that the patronage of connected religious dynamics—not just the contingencies of trade, land, labour, and statecraft—was an essential aspect of Company business. At the same time, mediating Buddhist connection was a dangerous, sometimes perilous undertaking. Analysing VOC records alongside Laṅkān and Siamese historical chronicles and travelogues reveals that what were initially friendly connections at first necessitated, and later intensified certain forms of danger. We begin with perilous shipwrecks and diplomatic impasses across monsoon waters that eventually led to the restoration of an important but defunct Kandyan Buddhist ordination lineage, and conclude with the aftermath of a failed assassination attempt in 1760 against the royal patron of that lineage transmission. I advance the notion of “dangerous friendships” to characterise how Buddhist courts and European traders worked together to first generate, and then exploit, friendly religious connections.

AbstractObjective:We evaluated associations between food insecurity (FI) and the quality and quantity of sleep in adults (≥18 years).Design:The current study represented a systematic review and meta-analysis of observational studies.Setting:Databases of PubMed, Scopus, Embase and Web of Science were searched from inception until 6 June 2022. Meta-analyses were conducted using random-effects models, and effect sizes were reported as OR and 95 % CI.Participants:Data from ten eligible observational studies, including 83 764 participants, were included.Results:FI was associated with an increased risk of poor sleep quality (OR = 1·45; 95 % CI (1·24, 1·70), I2 = 95, P < 0·001, n 7). Besides, subgroup analysis showed increased risk of poor sleep quality corresponding to the severity of FI across mild (OR = 1·31; 95 % CI (1·16, 1·48), I2 = 0 %, P < 0·001, n 5), moderate (OR = 1·49; 95 % CI (1·32, 1·68), I2 = 0 %, P < 0·001, n 5) and severe (OR = 1·89; 95 % CI (1·63, 2·20), I2 = 0 %, P < 0·001, n 5) levels. Similarly, subgroup analysis by sleep problems showed that FI was associated with an increased the risk of trouble falling asleep (OR = 1·39; 95 % CI (1·05, 1·83), I2 = 91 %, P = 0·002, n 3) and trouble staying asleep (OR = 1·91; 95 % CI (1·37, 2·67), I2 = 89 %, P < 0·001, n 3). Moreover, FI was associated with the odds of shorter (OR = 1·14; 95 % CI (1·07, 1·21), I2 = 0 %, P < 0·001, n 4) and longer sleep duration (OR = 1·14; 95 % CI (1·03, 1·26), I2 = 0 %, P = 0·010, n 4).Conclusions:Collective evidence supports that FI is associated with poor sleep quality and quantity in adults. Preventative and management strategies that address FI may provide health benefits beyond improving nutritional status per se.
Two sides of the coin: exploring the duality of corruption in Latin America
Authors: Hugo Ella , Savage David A. , Schneider Friedrich , Torgler Benno 
Published: November 2022

AbstractThe ambiguous phenomenon of corruption has long been the cause of great theoretical debate in economics. By using Structural Equation Modelling, with the two types of corruption as a latent variable, this paper employs causal and indicative variables to the Latin American region to test for rent seeking and systemic corruption during 1980–2018. The findings provide evidence for two types of corruption, one generated by greed, and the other a solution to market failures. Such results support the view that corruption encompasses a complex set of social behaviours that may require a stronger definitional approach.
A Positive Feedback Between Crustal Thickness and Melt Extraction for the Origin of the Martian Dichotomy
Authors: Bonnet Gibet Valentin , Michaut Chloé , Wieczorek Mark , Lognonné Philippe 
Published: November 2022

AbstractA North/South difference in crustal thickness is likely at the origin of the Martian dichotomy in topography. Recent crustal thickness maps were obtained by inversion of topography and gravity data seismically anchored at the InSight station. On average, the Martian crust is 51–71 km thick with a southern crust thicker by 18–28 km than the northern one. The origin of this crustal dichotomy is still debated although the hypothesis of a large impact is at present very popular. Here, we propose a new mechanism for the formation of this dichotomy that involves a positive feedback between crustal growth and mantle melting. As the crust is enriched in heat‐producing elements, the lid of a one‐plate planet is hotter and thinner where the crust is thicker, inducing a larger amount of partial melt below the lid and hence a larger rate of melt extraction and crustal growth. We first demonstrate analytically that larger wavelength perturbations, that is, hemispherical perturbations, grow faster because smaller wavelengths are more attenuated by thermal diffusion. We then use a parameterized thermal evolution model with a well‐mixed mantle topped by two different lids characterized by their thermal structures and thicknesses to study the growth of the crust in the two hemispheres. Our results demonstrate that this positive feedback can generate a significant crustal dichotomy.

AbstractThe heterogeneity of cancer-associated fibroblasts (CAFs) might be ascribed to differences in origin. CD10 and GPR77 have been reported to identify a chemoresistance-inducing CAF subset in breast cancer. However, the precise mechanism for the formation of the CD10+GPR77+ CAFs remains unknown. In this study, we found that CCL18 expression was positively correlated with the density of CD10+GPR77+ CAFs in breast cancer and associated with a poor response to chemotherapy. Moreover, CCL18 secreted by tumor-associated macrophages (TAMs) activated a CD10+GPR77+ CAF phenotype in normal breast-resident fibroblasts (NBFs), which could then enrich cancer stem cells (CSCs) and induce chemoresistance in breast cancer cells. Mechanistically, CCL18 activated NF-κB signaling via PITPNM3 and thus enhanced the production of IL-6 and IL-8. Furthermore, intratumoral CCL18 injection significantly induced the activation of NBFs and the chemoresistance of xenografts in vivo. In addition, targeting CCL18 by anti-CCL18 antibody could inhibit the formation of CD10+GPR77+ CAFs and recover the chemosensitivity in vivo, leading to effective tumor control. Collectively, these findings reveal that inflammatory signaling crosstalk between TAMs and fibroblasts is responsible for the formation of the CD10+GPR77+ CAFs, suggesting CCL18–PITPNM3 signaling is a potential therapeutic target to block the activation of this specific CAF subtype and tumor chemoresistance.

AbstractRecurrent implantation failure (RIF) is a rather thorny problem in the clinical practice of assisted reproductive technology. Due to the complex aetiology of RIF, its pathogenesis is far from fully understood, and there is no effective treatment available. Here, We explored the regulatory mechanism of the four half-domains of LIM domain 1 (FHL1), which is significantly downregulated in the endometrium of RIF patients, in blastocyst-epithelial adhesion. Indeed, FHL1 expression was dramatically increased in normal female mid-secretory endometrial epithelial cells and was abnormally reduced in RIF patients. Furthermore, FHL1 overexpression promoted blastocyst-epithelial adhesion, and interfering with FHL1 expression in the mouse uterus significantly inhibited embryo implantation. Mechanistically, FHL1 did not regulate HOXA10 mRNA expression but increased HOXA10 protein stability and activated HOXA10, thereby promoting its regulation of downstream gene expression and the β3 integrin/FAK pathway. Meanwhile, FHL1 regulates HOXA10 function by increasing HOXA10 deacetylation through enhanced binding of HOXA10 and SIRT2. SIRT2-specific inhibitors can significantly inhibit this effect. In the endometrial epithelial cells of RIF patients, the correlation between FHL1 and HOXA10 and its downstream target genes has also been verified. Finally, our data indicated FHL1 is a regulatory molecule that promotes blastocyst-epithelial adhesion. Altogether, downstream dysfunction due to aberrant FHL1 expression is an important molecular basis for embryo implantation failure in patients with RIF and to provide new potential therapeutic targets.
