Exploring the social power of Christmas: a prospective qualitative study of assigning meaning to Christmas along the life course
Authors: Cucu-Oancea Ozana
Published: July 2022

This article relies on a prospective qualitative study, that provides valuable insight into the mechanism through which the meaning of holidays is built over time. Following a life course perspective, the article analyses the continuities as well as the twists and turns of the meaning of Christmas in relation to significant turning points that occur along the paths of individual lives in transition to adulthood. Grounded on an inductive approach, the study draws on longitudinal qualitative data collected through solicited diaries, kept by 14 young Romanian adults, around Christmas time, along four panel waves (2004, 2010, 2016, 2020). Results show that there is no universal configuration of the meaning of Christmas, but rather a diversity of personalised dynamic configurations, in line with individuals’ subjective realities, which are sensitive to family traditions passed down during socialisation, and constantly updated with each generation that assumes them, but also to significant life events that occurred on their early adult life course trajectories, determining a re-evaluation of attitudes about self, life, religion and others. The article concludes that Christmas, as a social construct, is a malleable bearer of values, which acts both as a ‘sword’ and as a ‘shield’ that diarists use according to the needs, wishes and challenges that arise in their transition from adolescence to enhanced adulthood.
Measuring BRDF for curved surfaces based on parabolic reflection
Authors: Inoue Shinichi , Igarashi Yoshinori , Hoshi Takeyuki , Tsumura Norimichi
Published: July 2022

In this study, we introduce a measurement method for the bidirectional reflectance distribution function (BRDF) for curved surfaces. Nearly all BRDF measurements assume that the target surface is planar. This is because if the object is non-planar, the reflection angle changes from position to position, making accurate measurement impossible. However, most real objects are curved. We have overcome this problem by applying the paraboloid reflection principle. If the curved target surface is a paraboloid, the light focused on its focal point is reflected as parallel light, as in a parabolic antenna. The BRDF can be measured as the deviation angle from this parallel light direction. Here, we demonstrate that this can significantly improve the BRDF measurement accuracy for curved surfaces.

Establishing the content of gender stereotypes across development
Authors: Sullivan Jessica , Ciociolo Angela , Moss-Racusin Corinne A.
Published: July 2022

Gender stereotypes shape individuals’ behaviors, expectations, and perceptions of others. However, little is known about the content of gender stereotypes about people of different ages (e.g., do gender stereotypes about 1-year-olds differ from those about older individuals?). In our pre-registered study, 4,598 adults rated either thetypicalityof characteristics (to assessdescriptivestereotypes), or thedesirabilityof characteristics (to assessprescriptiveandproscriptivestereotypes) for targets who differed in gender and age. Between-subjects, we manipulated target gender (boy/man vs. girl/woman) and target age (1, 4, 7, 10, 13, 16, or 35). From this, we generated a normed list of descriptive, prescriptive, and proscriptive gender-stereotyped characteristics about people across the early developmental timespan. We make this archive, as well as our raw data, available to other researchers. We also present preliminary findings, demonstrating that some characteristics are consistently ungendered (e.g., challenges authority), others are gender-stereotypic across the early developmental timespan (e.g., males from age 1 to 35 tend to be dirty), and still others change over development (e.g., girls should be submissive, but only around age 10). Implications for gender stereotyping theory—as well as targets of gender stereotyping, across the lifespan—are discussed.
A double scrambling-DNA row and column closed loop image encryption algorithm based on chaotic system
Authors: Ran Weiyu , Wang Erfu , Tong Zhiyong
Published: July 2022

In this paper, a dynamic update algorithm of double scrambling-DNA row and column closed loop based on chaotic system is proposed. The classical scrambling and diffusion structure are used in the whole process. In the scrambling stage, a new pixel reconstruction method is proposed by combining the Hilbert curve with Knuth-Durstenfeld shuffle algorithm to overcome the shortcoming of nearby storage of Hilbert curve. This method reconstructs the pixel matrix of one-dimensional vector according to the Hilbert curve coding method, and achieves good scrambling effect, while reducing its time complexity and space complexity. In the diffusion stage, combining the plaintext row, the ciphertext row and the key row, and taking advantage of the parallel computing power and high storage density of the DNA encoding, the existing block diffusion operation is improved, and the two-round diffusion of the DNA encoding is proposed. When the last line of ciphertext is generated, the first line of ciphertext is updated and the closed-loop dynamic update of the encryption system is realized. Finally, SHA-256 is used to give the secret key and calculate the initial value of the chaotic system. The simulation results show that the “double scrambling-DNA row and column closed loop dynamic” update algorithm proposed in this paper can effectively improve the efficiency of information transmission and have high security.

Published: July 2022

Objectives

Hypoglycemia unawareness (HUA) in patients with FCPD is common with an unclear etiology. We evaluated the prevalence, characteristics of HUA, glycemic variability (GV), its possible association with pancreatic glucagon secretion & cardiac autonomic function in patients with FCPD.

Methods

A two-week ambulatory glucose profile (AGP) and cardiac autonomic function test was done in patients with FCPD (n = 60), and categorized into UNAWARE (n = 44) and AWARE (n = 16) groups based on the Hypoglycemia Unawareness Index (HUI) score. Glycaemic variability was assessed from the AGP data using Easy GV 9.0.2 software. A subset of patients from both the groups (n = 11) underwent a mixed-meal challenge test and were compared with healthy individuals (controls; n = 11).

Results

HUA was evidenced in 73% (44/60) of patients with FCPD. Significant hypoglycemia, nocturnal hypoglycemia, duration of hypoglycemia and poor cardiac autonomic functions (p = 0.01) were prominent in the UNAWARE group. The overall GV was greater in the UNAWARE group. In the UNAWARE group, significantly reduced fasting and post prandial glucagon levels negatively correlated with HUI (r = -0.74, p < 0.05) and GV-hypoglycemia indices (p < 0.05) In contrast, significantly higher post prandial glucagon levels in the AWARE group positively correlated with post prandial hyperglycemia (r = 0.61, p < 0.05).

Conclusion

Heterogeneity in patterns of glucagon secretion were significantly associated with HUA and GV. Reduced glucagon levels contribute to greater risks of HUA, nocturnal hypoglycemia and greater GV, while hyperglucagonemia predisposes to postprandial hyperglycemia and hypoglycemia awareness in patients with FCPD.
A rapid and accurate method for estimating the erythrocyte sedimentation rate using a hematocrit-corrected optical aggregation index
Authors: Higuchi Makoto , Watanabe Nobuo
Published: July 2022

Although both the erythrocyte sedimentation rate (ESR) and optically measured erythrocyte aggregation parameters are affected by the hematocrit, this interaction is not considered by the method used to estimate ESR that considers aggregation parameters. In this study, we investigated the relationship between the ESR obtained by the Westergren method and that obtained with an aggregation parameter, namely, the aggregation index (AI) of multiple hematocrit values and fibrinogen-spiked samples with an analysis time of 5–60 s, and attempted to develop a rapid and accurate ESR estimation method. The AIs obtained from 5- and 10-s optical measurements with a fixed hematocrit were highly correlated with the erythrocyte sedimentation velocity. Furthermore, the rate of the AI increase with an increasing hematocrit was not significantly affected by the fibrinogen concentration at these measurement times. On the basis of these results, we defined the hematocrit-corrected aggregation index (HAI). The exponential function of the HAI obtained from the 5-s measurement agreed well with the sedimentation velocity calculated to eliminate the effect of hindered settling, and the HAI and hematocrit could be used to calculate the time constant of the sedimentation curve with a linear regression equation. The ESR value at 1 h was calculated based on the modified Stokes’ law and the HAI obtained from the 5-s measurement and showed an excellent correlation (R = 0.966) with the ESR value obtained by the Westergren method over a wide range of hematocrit and fibrinogen concentrations.

Published: July 2022

To examine the association of fetal fraction with a wide spectrum of pregnancy-related complications among Chinese population, we carried out a single-institution retrospective cohort study of women with negative Noninvasive prenatal testing (NIPT) results and singleton pregnancies between May 2018 and May 2020. Indicators of pregnancy-related complications were examined individually, including preterm birth, low birth weight, hypertensive disorders of pregnancy, gestational diabetes, oligohydramnios and intrahepatic cholestasis. We evaluated disease odds ratios (ORs) and 95% confidence intervals (CIs), after controlling for potential confounders including body mass index (BMI), maternal age and gestational week at NIPT. A total of 3534 women were included in our analyses. Women with fetal fraction<15.15% had increased risk of gestational hypertension (OR 4.41, CI [1.65, 12.45]) and oligohydramnios (OR 2.26, CI [1.33, 3.80]) compared to women with fetal fraction≥15.15%. No significant associations with fetal fraction were found for preterm birth, low birth weight, gestational diabetes, and intrahepatic cholestasis. In Summary, fetal fraction is inversely associated with the risk of gestational hypertension and oligohydramnios.

International Standing Conference for the History of Education (ISCHE)
Authors: Hernández Huerta José Luis , Payà Rico Andrés
Published: July 2022

The objective of this study is to map the international networks of research, circulation, and scientific communication in the history of education, at a global level. In order to do so, we analyse the activity of the International Standing Conference for the History of Education (ISCHE). The focus is placed on the following: the make-up and organisation of the community of education historians; the arenas set up to encourage collaboration, debate and consensus in research in the field; collaboration among researchers, and the influence of transnational perspectives; avenues of research and areas of focus; and the communication channels by which ideas and findings are published and exchanged. The documentary sources used are the minutes of ISCHE annual congresses and general assemblies, alongside other research and previous studies. The main variables are: the language in which papers are published; the countries from which the authors come; international collaboration among authors; the historical period analysed; and the country or region being studied. After examining over 3600 contributions, we conclude that, globally, the international network in history of education is in good health, and there is an appetite for research with an international focus. However, there is room for improvement by promoting more extensive international collaboration among researchers, expanding the scope of research to take a supranational or even global view, and extending the study of the history of education to pre-modern times.
THE USE OF FLUID-FILLED CATHETERS AS REFERENCE BLOOD PRESSURE MONITORS
Authors: Mikhailov Yegor , Fabián Vratislav
Published: July 2022

The standard ISO 81060–2:2018 allows the use of invasive blood pressure monitoring systems as reference gauges in clinical trials of automated non-invasive automated sphygmomanometers. The reference measuring system is subject to requirements for a maximum permissible error of ±2 mmHg, and the resonant frequency and damping coefficient must also be characterized. The 'catheter-sensor' system used in clinical practice only has defined parameters required by the standard for the chamber with the pressure sensor. The characteristic parameters of the whole measuring system cannot be defined even when the type of catheter used is known, because after every irrigation the system changes the values of its natural frequency (fn) and damping ratio (ζ). These parameters directly define the frequency response of the system, its resonant frequency and the damping coefficient. The characteristic parameters of the 'catheter-sensor' system were defined on the basis of an analysis of a second-order linear model and the measurement of the step response of the real system. Measurements have shown that repeated irrigation of the same 'catheter-sensor' system can change the value of the system’s natural frequency by tens of Hz. In well-irrigated systems, the accuracy required by the standard was met. The following values were determined for this system: fn = 38.8 Hz and ζ = 0.130. In the second case, when the system was probably affected by air bubble compliancy, the measurement accuracy was much lower. The discovered deviation was tens of mmHg. This system had fn = 6.5 Hz a ζ = 0.281.

Published: July 2022

The use of information and communication technologies in education and teacher training is a topic investigated in various areas of knowledge. Recognizing aspects related to pedagogical problematization using specific technologies beyond the technical use of resources in pedagogical practices has also been a concern in this ​​research area. In this scenario, the Remote Laboratories present tools that can contribute to developing experimental practices, incorporating technologies that contribute to the student's scientific education. This work investigates the perceptions of chemistry students and science teachers regarding an activity that involves a practical activity in the Remote Laboratory. Data collection was using questionnaires, analyzed qualitatively through the Discursive Textual Analysis technique. Results show positive perceptions about this type of laboratory in terms of its versatility to face real problems and in environments with few resources and possibilities for pedagogical actions aimed at working with active methodologies, promoting student participation. Most of the negative perceptions refer to aspects that are not directly related to the remote laboratory but are associated with the investigative nature of the activity. Some perceptions refer to topics to be improved, such as the delay in the experiment transmission. It was possible to promote a process of reflection on the use of these resources.

Authors: De Menezes João Paulo
Published: July 2022

A transição do ensino online durante o bloqueio escolar provocado pelo COVID-19 suscitou desafios para formação inicial de professores, em especial nas disciplinas de práticas pedagógicas. A literatura existente sobre o impacto da pandemia no setor educação é predominantemente descritiva e focada nas dificuldades enfrentadas pelos professores durante o processo de transferência para o ensino online, principalmente no setor de ensino superior, no entanto poucos trabalhos versam sobre as crenças de autoeficácia na formação inicial docente. Considerando o cenário imposto, o objetivo da pesquisa foi avaliar os níveis de autoeficácia, emoções, estratégias de enfrentamento e inteligência emocional em uma amostra de estudantes universitários, e como esses elementos se relaciona as crenças de autoeficácia desse grupo. A amostra foi composta por vinte estudantes matriculados na disciplina de estágio supervisionado obrigatório. Foram realizadas análises descritivas, correlações bivariadas e regressão multivariada. A análise de correlação bivariada mostrou relação inversa significativa entre autoeficácia e raiva, ansiedade, autocrítica e atenção emocional. Além disso, foi encontrada uma correlação direta entre a autoeficácia, a emoção do prazer e as estratégias de reestruturação cognitiva. A análise de regressão multivariada mostrou que as emoções dos professores em formação (prazer, raiva, ansiedade), estratégias de enfrentamento (autocrítica e reestruturação cognitiva) e a inteligência emocional (atenção emocional) foram significativamente relacionados à variável dependente. Em conclusão, este trabalho pode contribuir para um melhor entendimento dos fatores relacionados à percepção geral da crença de autoeficácia em estudantes matriculados nos estágios supervisionados obrigatórios.
Teacher autonomy in the age of performance-based accountability: A review based on teaching profession regulatory models (2017-2020)
Authors: Parcerisa Lluís , Verger Antoni , Pagès Marcel , Browes Natalie
Published: July 2022

In recent decades, the governance of educational systems has experienced dramatic changes in many countries. Schools have been given more autonomy whilst being held increasingly accountable at the central level through standardized testing and other forms of external evaluation. The mechanisms of performance-based accountability (PBA) and the consequences attached to test results vary. In high-stakes systems, teachers’ careers are more directly connected to students’ performance, and low performing schools might risk closure, whereas in lower-stakes systems, the official administrative consequences of accountability for school actors are more symbolic than material. The main aim of this paper is to understand the impact of different forms of PBA on teachers’ work from a comparative perspective. Most research on this topic is based on single-context case studies, which makes it difficult to understand the impact of policy factors and professional contexts in teachers’ decisions and autonomy. To address this challenge, we review recent investigations (2017-2020) on the topic and compare their findings in different teachers' regulatory contexts. The review includes 101 articles from the SCOPUS and Web of Science databases. We find that evidence on the impact of PBA on teachers’ perceptions and beliefs are variegated, and that the implications of PBA on teachers’ autonomy does not only depend on the level of accountability stakes, but on teachers’ professional regulation.

Method: Based on the assessment, individualized education plan team selected tools and symbols and established support plans. To support play and daily participation of the child, communication boards and picture cards using KAAC symbols were placed in the classroom for each activity. Prior to intervention, communication-partner training was conducted and AAC tools and vocabulary were modified four times during the intervention. When the child expressed his intention via AAC, his communication partner responded immediately with verbal feedback. Results: In terms of communication, first, the child's intention was clearly conveyed to the partner. Second, expressions of intention were elaborated. Third, vocabulary on various topics was used. Fourth, spontaneous speech was increased. In terms of social interaction, first, the overall frequency of peer interaction was increased. Second, direct interaction among peers and the child was increased. Third, the child actively participated in daily routines. In terms of challenging behavior, although it was different depending on an adult supporting him, the attention-seeking challenging behavior was slightly decreased. Conclusion: These results support AAC intervention for children with Down Syndrome in inclusive kindergarten that is modified continuously and implemented through activity-based embedded intervention.

An insight on Vietnamese bio-waste materials as activated carbon precursors for multiple applications in environmental protection
Authors: Ngo Thi Cam Quyen , Tan Lam Van , Thao Nguyen Phuong , Tran Thi Kim Ngan , Hoang Ngoc Bich
Published: July 2022

Vietnam is known as an agricultural country with a variety of agricultural crops. In addition to agricultural by-products, bio-waste is the by-product from livestock waste, forestry, industry, and daily life. They affect the soil, water, and air environment by self-degradation processes in the environment. Therefore, researchers have come up with ideas for the usage of the by-products to decrease the amount of waste and minimize the environmental effects. In Vietnam, the by-products were used by researchers to produce bio-ethanol, fertilizers, composites, and activated carbon (AC). AC is one of the materials used to rapidly reduce the number of agricultural by-products by researchers. The synthesis process is optimized for the highest yield, while the physicochemical properties are also clearly analyzed through the X-ray diffraction, Fourier transform infrared, and Bacterial endotoxin testing assays. The average recorded specific surface area was about 300 m2 g−1. The functional groups and surface structure showed that the material has an amorphous structure with –OH, –CH, –CC, –C═C, –C═O groups. The AC from agricultural waste had been studied and applied to treat pollutants present in water.

Authors: Erol Ayhan , Bilici Vildan Özkan , Yönetken Ahmet
Published: July 2022

The scope of this study, that is, the effect of the elastic modulus obtained by ultrasonic method on the physical and mechanical properties of tungsten carbide (WC)-based ceramic–metal composites, which have Ni and Co metallic binder composition produced by powder metallurgy and represented by high strength and hardness criteria, was investigated. In order to obtain composite samples in the study, it was sintered in a microwave furnace at different temperatures to combine the powder particles prepared at the rate of 60% Ni, 20% Co, and 20% WC by weight. Then, the velocities and longitudinal attenuation values of longitudinal and shear ultrasonic waves along the composite sample were measured using the ultrasonic pulse-echo method. The elastic modulus of the composites was determined using ultrasonic velocities and sample density. Hardness testing, scanning electron microscopy (SEM), and X-ray diffraction (XRD) analyses were also performed. The results show that the elastic modulus increases with the increase in sintering temperature and ultrasonic wave speeds, but decreases with the longitudinal attenuation value, considering the SEM images and XRD analysis. There is also a linear relationship between elastic modulus and stiffness.
The Liberation of Fairy-Tale Heroinesin James Finn Garner’sPolitically Correct Bedtime Stories
Authors: Vlašković Ilić Biljana
Published: July 2022

This paper reexamines the way in which traditional fairy tales depict famous heroines (Little Red Riding Hood, Rapunzel, Cinderella, and Snow White) by comparing them to their “liberated” versions from James Finn Garner’sPolitically Correct Bedtime Stories. We argue that the greatest value of the modern adaptations of classic fairy tales lies in their enabling us to see the world as a child might, introducing at the same time the grown-up theme of the liberation of women and breaking the pattern of portraying easily led, ineffectual, and vulnerable female characters in children’s literature.
The Many Arts of Writing a Babylonian National History
Authors: Boivin Odette
Published: July 2022

Any discussion about historiography in Mesopotamia leads sooner or later—and it is usually sooner—to the question of genre. This article explores aspects of this question by examining how, in the wake of political, intellectual and cultural developments which marked the late second and the beginning of the first millennium BCE, various streams of historiographic practice converged towards the writing of a Babylonian national history, or rather, national histories. In order to do so, three roughly contemporary sources, written in different milieus, are discussed as instances of this phenomenon: the Chronicle of Ancient Kings A, the Chronicle Concerning the Early Years of Nebuchadnezzar II, and the Imgur-Enlil Inscription of Nabopolassar. The contents, form, sources used, and intentions of writing of each of them are evaluated, and a number of shared themes and approaches are identified and proposed as elements of seventh/sixth century national history writing in Babylonia.
Synthesis and study of magnesium complexes derived from polyacrylate and polyvinyl alcohol and their applications as superabsorbent polymers
Authors: Kadhim Saja A. , Hameed Awham M. , Rasheed Rashed T.
Published: July 2022

Novel superabsorbent polymers (SAPs) were created by solution polymerization at ambient temperature using potassium polyacrylate (KPA), polyvinyl alcohol (PVA), and magnesium chloride as a cross-linking agent with different weights of 0.4, 0.5, 0.6, 0.7, 0.8, and 1 g for KPA and 0.33, 0.44, 0.55, 0.733, and 1.1 g for PVA. Fourier transforms infrared (FTIR) and UV-Vis spectroscopy were used to determine the chemical composition of the SAP complexes. The outcomes revealed that the KPA and PVA successfully interacted with the magnesium chloride. The morphology of the surfaces shows a uniform porous interconnected microstructure as revealed by field emission scanning electron microscopy. The effective preparation was confirmed by thermal characterization (thermogravimetric analysis and differential scanning calorimetry) of the SAPs. The influence of the cross-linker agent on the SAPs’ water absorbency was examined. The magnesium polyacrylate (Mg-PA) (0.6 g of MgCl2) SAP has a maximum swelling capacity of 650%, while that of magnesium polyvinyl alcohol (Mg-PVA) (0.55 g of MgCl2) was 244%. The findings confirmed that the SAPs have excellent swelling and water-retaining capabilities. The strategy used in this investigation may function as a model for developing and widespread usage of SAPs in agriculture and horticulture.
A geometric morphometric analysis of geographic variation in the Cape Short-eared gerbil, Desmodillus auricularis (Rodentia: Gerbillinae)

Published: July 2022

The genus Desmodillus is monospecific, consisting of only the Cape short-eared gerbil (Desmodillus auricularis). Despite being widely distributed across southern Africa, previous studies did not find evidence of intraspecific phenotypic geographic differentiation. The objectives of this study is to use geometric morphometrics to investigate if and how the skull of D. auricularis varies spatially. It examines the covariation of skull morphology with broad spatial (latitude and longitude) and climatic variables, based on a sample of 580 specimens from southern Africa (Botswana, Namibia, and South Africa). The results did not support the differentiation of D. auricularis populations into distinct geographically isolated phenotypic groups. However, there is strong evidence for clinal variation in skull morphology; the most prominent pattern being a decrease in size from the west (closest to the South Atlantic coast) to the east (towards the continent’s interior). Shape variation was not localized in any skull region and seem to be driven mostly by size (allometry), although it also covaried significantly with latitude and longitude. Statistically significant skull shape sexual dimorphism was also detected, with males having larger crania than females. Spatial clinal variation in skull morphology was mostly associated with differences in the aridity of the habitats relative to their distance from the coast as evidenced by precipitation-related bioclimatic variables—annual precipitation (BIO12), precipitation of driest month (BIO14), and precipitation of driest quarter (BIO17)—covarying the most with skull morphology. This could be driven by either the climate influencing local resources available to populations or by the climate directly instigating phenotypic climatic adaptations.

Research has suggested a significant prognostic value of ST-T changes in various cardiovascular diseases and malignant tumors. However, their role in predicting prognosis in patients with peripheral T-cell lymphomas (PTCLs) remains unknown. Here, we investigated the prognostic potential of ST-T changes in all-cause mortality of PTCLs patients. In total, 131 patients with PTCLs between January 2015 and April 2020 were enrolled. Univariable and multivariable COX proportional hazards regression models were used to find the relationship between ST-T changes and all-cause mortality in these patients. A significant difference in all-cause mortality was found between patients with ST-T abnormalities and those without definite abnormalities in the ST-T segments (P = 0.027). Multivariable Cox risk regression analysis indicated that patients with ST-T changes had greater all-cause mortality than patients with normal ST-T segments in the intermediate-high/high-risk groups (P < 0.001). In addition, ST-T changes were markedly distinction in patients with hypoproteinemia than in those with no definite abnormalities in the ST-T segments (P = 0.021). ST-T changes may serve as potential, simple, and effective prognostic factors for all-cause mortality in PTCLs patients, especially in the intermediate-high/high-risk and hypoproteinemia groups. Therefore, regular ECG monitoring is recommended to guide the clinical treatment of patients with PTCLs.

LetKbe a fixed proper convex cone contained in a separable Banach spaceE. Our main result in this note is a construction of a fuzzy process taking values inK-positive fuzzy sets, i.e. in a coneFcconvK(E)$ \mathcal F_{\mathrm{cconv}}^{K}(E) $of fuzzy sets contained inK. We prove that this process can be considered as a fuzzy Lévy subordinator (with values inFcconvK(E)$ \mathcal F_{\mathrm{cconv}}^{K}(E) $) or simplyfuzzyFcconvK(E)$ \mathcal F_{\mathrm{cconv}}^{K}(E) $-subordinator.

Published: July 2022

A novel fiber-optic vector magnetic field sensor and its sensing quality dependent of fabrication method has been proposed and investigated. The proposed sensor has two surfaces on the tip of a multimode fiber, which is used as the sensing probe. By plating different thickness of gold film on the surfaces, surface plasmon resonance (SPR) can be generated and the signal can be reflected by the surfaces as well. Meanwhile, magnetic fluid (MF) as the magnetic field sensitive material is packed around the sensing probe. The experimental results prove that the response of MF to external magnetic field can be used to sense magnetic field intensity and direction via monitoring the dip wavelength of SPR. The obtained refractive index (RI) sensitivities are 2105 nm/RIU (RI range: 1.332–1.365) and 6692 nm/RIU (RI range: 1.372–1.411), magnetic field intensity sensitivities are 11.67 nm/mT (0°), and −0.47 nm/mT (90°). Besides, the proposed sensing probe is ultracompact and the footprint is extremely small (the length of sensing part is only 615 μm), which is very helpful for magnetic field detection in narrow space and gradient field.

Extended warranty decision model of failure dependence wind turbine system based on cost-effectiveness analysis
Authors: Dong Enzhi , Cheng Zhonghua , Wang Rongcai , Zhang Yuexing
Published: July 2022

The wind turbine system is the core equipment of wind power generation. Scientific formulation of an extended warranty (EW) scheme to optimize the cost-effectiveness ratio per unit time for a wind turbine system is one of the key concerns both for users and manufacturers. Based on the failure dependence analysis of the multi-component system, the EW cost model and availability model of the multi-component system are established. Based on the EW cost model and availability model, the cost-effectiveness ratio model per unit time is constructed. Through the case study, the optimal EW scheme of the wind turbine system is obtained via genetic algorithm, so as to minimize the cost-effectiveness ratio per unit time. The results of fitting prediction analysis and flexible decision analysis show that the model can excellently predict the minimum warranty cost and maximum availability of failure dependence wind turbine systems and can supply different EW schemes for users and manufacturers to choose from under a specific cost–effectiveness ratio. Through sensitivity analysis, reasonable suggestions for optimizing the EW scheme of the wind turbine system are proposed.

Objectives

In COVID-19, severe lung involvement develops in some patients. The reason for the predisposition to lung involvement in some patients is not yet fully understood. Genetic variabilities in angiotensin-converting enzyme (ACE) may explain why some patients are more susceptible to lung injury. Thus, the ACE gene insertion/deletion (I/D) polymorphism was investigated in COVID-19 patients with and without lung involvement.

Methods

The study involved 216 patients who were divided into two groups as with and without pulmonary involvement according to their thoracic computed tomography (CT) scan findings. The ACE I/D gene polymorphism was determined.

Results

Carriers of the DD genotype had a 4.05-fold (OR=4.05, 95% CI: 1.66–9.86, p=0.001) greater incidence of pulmonary involvement. The probability of lung involvement was 2.41-fold higher in D allele carriers (OR=2.41, 95% CI: 1.62–3.60, p=0.000). The I allele was found to be protective and diminished the occurrence of lung involvement (OR=0.41, 95% CI: 0.28–0.62, p=0.000).

Conclusions

In COVID-19 patients, the I allele may lower the risk of lung injury and provide a protective effect. Conversely, the D allele may raise the risk of lung injury and lead to poor outcomes.

Both recently and historically, naturalistic datasets and corpus analyses have played an important role in the formulation and testing of key theories and hypotheses in language development and use. The present work details ways in which an existing tool, the Electronically Activated Recorder (EAR), can be used in the cognitive and language science domains to better understand the content of day-to-day speech. From our sample of 75 young adult college students – a population with diverse linguistic experiences – we found enormous variability in the total amount of speech produced and the number of unique words spoken. Further, we discovered that individuals who speak frequently may not be the same individuals that produce long utterances, and we quantified the contexts in which individuals tend to speak. We argue that studies examining naturalistic speech in adults are rare, and through our data, we aim to demonstrate how the EAR can be used in novel ways to create both individual and group-level corpora of adults’ spoken language use.

Published: July 2022

Although drag driven wind turbine is regarded as an efficient rotor for low wind speed region, design reconfiguration is a continuous process in order to improve the performance of the rotor. The main governing factor that influences the performance of the rotor is the blade morphology. Hence, this paper presents a proposed nature inspired design approach for the development of drag driven wind turbine blade morphology. The design approach framework comprise of 3 main elements namely image processing, geometrical analysis and bio-hybridization. The proposed bio-hybridized design consist of blade mainframe curve inspired by nautilus shell and barnacle on the blade surface. It is found that integration of barnacle geometries on the surface of the blade has affected the performance of the rotor. Result shows that the peak Cm is at λ = 0.55 for experimental and CFD is Cm = 0.238 and Cm = 0.253 respectively. The proposed design resulted in experimental and numerical Cp = 0.113 and Cp = 0.127 respectively at 7 m/s and λ = 0.7. The presented design technique with appropriate design bio-element provides a systematic method for engineers to model wind turbine blade morphologies.
