A Cooperative D2D Content Sharing Scheme Using NOMA Under Social Ties

With the merit of bypassing the base station (BS) to directly communicate between user equipment (UE), D2D content sharing between socially connected users has revealed promising potential in future networks. However, D2D receivers (DRs) in different D2D pairs (DPs) may also have demand for additional content sharing services from the D2D transmitters (DTs), who also have considerable social ties with them, in other surrounding DPs to enhance or supplement their received sharing services. In this letter, we propose a cooperative D2D content sharing scheme using NOMA technique under social ties, where the DRs in different DPs, who have social similarities in interested files, separately spare a portion of the transmit power of their corresponding DT to each other to improve the received sharing services in DRs. Based on this, the performance of the proposed scheme underlaying cellular network with partial channel state information (CSI) is analyzed, which is suitable for distributed deployment. Finally, the simulations validate the effectiveness of our proposed scheme.
PROSODIC PATTERNS IN SYLHETI-ENGLISH BILINGUALS

Abstract The primary aim of this study was to investigate prosodic prominence across three groups of Sylheti-English bilinguals: first-generation who arrived as adults, first-generation who arrived as children, and second-generation, i.e., born in the United Kingdom to parents who grew up in Bangladesh. To measure prominence, f0, duration, and intensity were measured across disyllabic words in Sylheti and English. The results showed significant differences in the f0 analysis. Regarding monolinguals, Sylheti prominence displayed a rising contour, in contrast to the English falling contour. In Sylheti, the bilinguals born in the United Kingdom were the only group significantly different from the Sylheti monolinguals, displaying an English-like falling pattern in their Sylheti prominence. In English, the late arrival bilinguals displayed a Sylheti-like prominence realization, but the early arrivals and those born in the United Kingdom approximated the monolingual English prominence realization. Overall, language use patterns were the most significant factor related to the bilinguals’ prominence realization.
Related Party Transactions, Family Ownership, and Earnings Management in Indonesia

The purpose of earnings management practice is to reach the profit goals the company wants to achieve. Therefore, this study aims to determine the relationship between related party transactions and earnings management in Indonesia by balanced panel data from consumer goods companies listed on the Indonesia Stock Exchange (IDX) from 2017 to 2019. The number of samples used in this study was 102 firm-year observations. The results showed that related party transactions positively and significantly improved corporate earnings management, with discretionary accrual as a proxy. The presence of family ownership strengthens the relationship between related party transactions and earnings management. Also, it shows that the control variable: public accountant from BIG4, company size, company losses, and ROA affect accrual earnings management. The leverage does not affect accrual earnings management. The study result indicates that family business ownership encourages an entrenchment effect that is detrimental to the company. It is carried out through related party transactions then manipulated by using accrual earnings management practices.DOI: 10.26905/jkdp.v25i3. 5778
Tribological Behavior of Al2O3-MoO2-SiO2 Composite Ceramic Coating on Al-Zn-Mg-Cu Alloy

In order to enhance wear properties of Al-Zn-Mg-Cu alloy parts, Al2O3-MoO2-SiO2 composite ceramic coatings are formed on Al-Zn-Mg-Cu alloy by the DC micro-arc oxidation (MAO) method in the silicate electrolyte with sodium molybdate. Effects of sodium molybdate concentration on the structure characteristics and wear resistance of the composite ceramic coatings are analyzed by scanning electron microscopy, X-ray diffraction and the wear test, respectively. Analyses indicate that the composite coating consists of different states of Al2O3, MoO2 and mullite phase. With the addition of molybdate in the electrolyte, the morphology and structure are changed. The tribological behavior is greatly affected by the surface characteristics and hardness of the coatings. The composite coatings formed by adding 3 g/L of sodium molybdate electrolyte have the best wear resistance.
Retrieving Tarnished Daguerreotype Content Using X-ray Fluorescence Imaging—Recent Observations on the Effect of Chemical and Electrochemical Cleaning Methods

We report a study on the effect of chemical and electrochemical cleaning of tarnished daguerreotypes observed using X-ray fluorescence (XRF) microscopy with a micro-focussed X-ray beam from a synchrotron source. It has been found that, while both techniques result in some success depending on the condition of the plate and the experimental parameters (chemical concentration, voltage, current, etc.) the effect varies, and cleaning is often incomplete. The XRF images using Hg Lα,β at an excitation energy just above the L3 edge threshold produce fine images, regardless of the treatment. This finding confirms previous observations that if the bulk of the image particles remains intact, the surface tarnish has little effect on the quality of the original daguerreotype image retrievable from XRF.
Fabrication and Characterization of In0.9Ga0.1O EGFET pH Sensors

In this study, the In0.9Ga0. 1O sensing membrane were deposited by using the RF magnetron sputtering at room temperature and combined with commercial MOSFETs as the extended gate field effect transistor (EGFET) pH sensors. The sensing performance of the In0.9Ga0. 1O EGFET pH sensors were measured and analyzed in the pH value of range between 2 to 12. In the saturation region, the pH current sensitivity calculated from the linear relationship between the IDS and pH value was approximately 56.64 μA/pH corresponding to the linearity of 97.8%. In the linear region, the pH voltage sensitivity exhibited high sensitivity and linearity of 43.7 mV/pH and 96.3%, respectively. The In0.9Ga0. 1O EGFET pH sensors were successfully fabricated and exhibited great linearity. The analyzed results indicated that the In0.9Ga0. 1O was a robust material as a promising sensing membrane and effectively used for pH sensing detection application.
Calcium from Finger Millet—A Systematic Review and Meta-Analysis on Calcium Retention, Bone Resorption, and In Vitro Bioavailability

Calcium deficiency during child growth leads to osteoporosis in later stages of life. Finger millet is one of the calcium dense foods, with three times the level of calcium than milk, and the only cereal that contains high calcium content which is consistent across different varieties (364 ± 58 mg/100 g). Thus, finger millet has potential for addressing calcium deficiency naturally. This study aimed to determine the retention and impact of finger millet calcium on bone turnover through a systematic review and meta-analysis. Three human studies were eligible for systematic review. Of these, only two were eligible for meta-analysis to assess the retention of calcium in children of 9 to 12 years. One study on bone turnover markers was not used in the meta-analysis as at least two studies are required to conduct meta-analysis. Due to the lack of complete data only four studies were eligible for meta-analysis to assess the in vitro bioavailability of calcium from unprocessed and a range of different types of processed finger millet. The result shows that there was significant retention (p < 0.05) of 23.4 ± 2.9% calcium from finger-millet-based diet which could help bone accretion during child growth if finger-millet-based diet is consumed. The bone turnover marker study shows that the resorption of calcium reduced by 28% and 47% among peri and post-menopausal women respectively after feeding the nutria mixed grain ball. However, there is no significant change in bone formation marker. Depending on the type of processing, calcium bioavailability either increased or decreased. One in vitro study showed that calcium bioavailability from finger millet was 28.6% when boiled, whereas three studies on processing show that certain processing can double the calcium bioavailability to 61.4%. Irrespective of the type of processing, finger millets contribute to high calcium retention and extremely high bioavailable calcium and could be useful for healthy growth and in dealing with complications related to calcium deficiency.
Religious Identity Formation of Filipino Canadian Youth: Exploring Cluster Differences in Religiosity and Mental Health

ABSTRACT Individuals vary in how much exploration and commitment they invest in their identities, which results in different identity “statuses” across a population. Although the majority of Filipinos in Canada identify as Christian, how they each formed their religious identity status may be different, which would be important to understand given the strong relation between mental health and religiosity. Filipino Canadian youth (N = 181) aged 14 to 25 completed online questionnaires about their religious identity status, religiosity, and mental health. A cluster analysis was conducted on youth’s engagement with religious identity formation processes, and results revealed five religious identity statuses: Internalized, Ruminative Moratorium, Undifferentiated, Foreclosed, and Indifferent. Filipino youth with different religious identity statuses had distinct religious experiences and endorsed different levels of mental health. The study highlights the diverse religious experiences in a religiously homogeneous ethnic group which may have implications for mental health.
CHINESE PRODUCT-SERVICE SYSTEM INNOVATIONS ENABLED VIA GOVERNMENTAL POLICIES: THE E-SCOOTER CASE

Abstract Together with increasingly saturated and commoditized global markets companies are driven to shift their business focus, adopting a strategy where customer perceived value is in the spotlight, and where products are bundled with services to offer Product-Service Systems (PSS). In this research we study the emergence of PSS solutions in the Chinese market via a selected case study on e-scooters, based on the governmental decision to ban fossil-fuel scooters in the late 90s and how this has spurred both a fossil-to-electric transformation and a product-to-function transformation. As seen in this research PSS is also an approach that is working well in the Eastern society and especially in China, based on governmental policies. It is gradually being adopted and applied in local industries significantly by China's leading internet companies (Didi, Alibaba etc). The PSS concept represented by e-bike cases in China has gradually penetrated into different industries. With governmental decisions as the key turn-point, it can be seen in practice and development that China's related service industry is using e-bike PSS to carry out the new business model from selling e-bikes to providing service-oriented solutions.
Does Linguistic Similarity Affect Early Simultaneous Bilingual Language Acquisition?

It is well established that L2 acquisition is faster when the L2 is more closely related to the learner’s L1. In the current study we investigated whether language similarity has a comparable facilitative effect in early simultaneous bilingual children. The similarity between each bilingual child’s two languages was determined using phonological and typological scales. We compared the vocabulary size of bilingual toddlers learning different pairs of languages. Results show that the vocabulary size of bilingual children is indeed influenced by similarity: the more similar the languages, the larger the children’s vocabulary.
A Meta-Analysis of the Relationship between Cannabis, Opiates, Cocaine, Heroin, or other Illegal Drug Use and Student Academic and Behavioral Outcomes

The meta-analysis, that included 75 studies, examined the relationship between illegal drug consumption, on the one hand, and student academic and behavioral outcomes, on the other, for the middle school to college grade levels. The meta-analysis first (research question #1) addressed whether there is a statistically significant relationship between illegal drug consumption and student academic and behavioral outcomes. A second question assessed whether there was a statistically significant relationship between the consumption of specific kinds of illegal drugs and student academic and behavioral outcomes (research question #2). The third analysis distinguished between the effects for educational- and behavioral-outcomes to see whether the consumption of illegal drugs was associated with one more than the other (research question #3). Fourth, there were analyses to determine whether the effects that emerged under the first two research questions differed by the age of the student (research question #4). The fifth analysis (research question #5) assessed whether the effects that emerged under the first two research questions differed by the race of the student. The results indicated widespread statistically significant effects for all the drugs under study. The extent of the effects were considerably greater for college students than they were for middle school students.

Implementing telehealth with ANC made it possible to effectively detect early mental health and manage the problem. The result has also shown that telehealth has achieved a good satisfaction level. The common factors that influence telehealth's efficacy include income, education, the age of pregnant women, and gestational age. It can be concluded that telehealth with ANC can effectively improve mental health among pregnant women and be recommended for use by health care providers in pandemic COVID-19.
An Acousto‐Microrobotic Interface with Vision‐Feedback Control

Precise manipulations for micro/nano targets of synthetic particles and bio‐cells hold great promise for the next generation of nano robotic systems and micro‐machines. Although considerable efforts have been devoted to developing propulsion protocols for micro/nano‐manipulation, the limited intelligence without effective control for current microrobots prohibits them away from most sophisticated applications. Here, a novel approach integrating the vision feedback control (VFC) is presented into a microrobotic platform powered by acoustic fields to accomplish autonomous targets identification and optimization of the locomotion resolution. Driven by local enhanced acoustic streaming, microparticles in the vicinity of the linear manipulator could be transported along the given pathway. Via vision feedback control, the targets of microparticles are automatically recognized in the acousto‐microrobotic interface and driven toward the exact user‐defined destinations. The VFC integrated interface is also adoptable to multiple particle manipulations, where each particle is distinguished with unique index numbers for a convenient on‐demand selection. At last, this closed‐loop interface is validated to control the motion of bio‐cells, illustrating the good robustness and biological compatibility. The VFC based control strategy for acousto‐microrobotic interface is featured with favorable controllability and thus will have great potentials in myriad scenarios for smart micro/nano systems.
Pioneering orientation and the threat of imitation in tourism and hospitality firms: the role of knowledge strategy

ABSTRACT This paper focuses on the moderating role of knowledge strategy between threat of imitation and pioneering orientation (PO) in tourism and hospitality firms (THFs) located in cultural destinations. First, it studies the moderation of knowledge exploitation strategy and knowledge exploration strategy separately. Second, it analyzes the moderating effect of combined knowledge strategy, which includes exploitation and exploration. The sample consists of 215 THFs located in World Heritage Cities (WHCs) in Spain. The results show divergent moderating roles. While knowledge exploitation strategy positively moderates the relationship between the threat of imitation and PO, the moderating effect of knowledge exploration strategy is negative. Moreover, combined knowledge strategy also moderates the relationship between threat of imitation and PO. This study contributes to the empirical literature by analyzing different knowledge strategies and highlighting the need for simultaneous consideration of exploitation and exploration of knowledge in THFs located in tourism destinations.
Can international sports mega events be considered physical activity interventions? A systematic review and quality assessment of large-scale population studies

Abstract Amidst ongoing debate about the viability of physical activity (PA) legacies associated with hosting international sports mega events, this systematic review explores quantitative evidence from population studies that utilize repeated measures. This review is guided by the PRISMA protocol and includes article quality evaluation techniques from health intervention research. Structured Boolean searches were conducted across six databases and grey literature sources. In total, 12 studies were identified from the last two decades across four event typologies. Among these studies, 9 were evaluated as being of higher quality, but only 4 employed standard definitions or measures of PA. Among the higher quality studies, two-thirds found no evidence for statistically significantly PA legacies, although gaps and limitations precluded definitive assessment. Common concerns include limited evaluation of covariates, sweeping conclusions based on insufficient evidence, arbitrary conceptualization and operalization of PA, and lack of triangulation. Research recommendations for resolving the impasse are proposed.
Dynamic Mapping Based on Single Segment Substitution Lines for Plant Height in Rice

Background: Dynamic regulations of QTLs still remain mysterious. Single segment substitution lines and conditional QTL mapping, functional QTL mappings are ideal materials and methods to explore epistatic interactions, expression patterns and functions of QTLs for complex traits.Results: Based on single segment substitution lines five QTLs on plant height in rice were identified first in this paper, and then their epistatic interactions, expression patterns and functions were systemmatically studied by tailing after each QTL. Unconditional QTL mapping showed the five QTLs were with significant effects at one or more stages, all of which increased plant height except QTL1. They interacted each other as homeostatic mechanisms to regulate plant height with negative effects before 72d after transplanting and positive since then. Conditional QTL mapping revealed the expression quantities and periods for the five QTLs and their epistases. Temporal expression pattern was verified again by selective expressions of QTLs in specific periods. QTL1 expressed negatively while QTL2 and QTL4 positively, mainly occurring in the periods from 35 to 42d and from 49 to 56d after transplanting. Epistatic expressions were dispersedly in various periods, mainly with negative effects before 35d while positive since then. Functional QTL mapping discovered the five QTLs brought the inflexion point ahead of schedule, accelerated the growth and the degradation, and changed the peak of plant height, while their interactions had the opposite effects approximately. This paper uncovered the dynamic rules of five QTLs and their interactions on plant height systematically, which will be helpful to understand the genetic mechanism for developmental traits.Conclusions: Five single segment substitution lines were tested with significant additive, dominant and epistatic effects of QTLs on plant height. Additive and dominant expressions were mainly in two periods, while epistasis dispersedly. The five QTLs and their interactions significantly regulated the developmental trajectory of plant height.
Continued Exploration of Barley Genotype Contribution to Base Malt and Beer Flavor Through the Evaluation of Lines Sharing Maris Otter® Parentage

Abstract Heirloom barley (Hordeum vulgare L.) varieties remain interesting to maltsters and brewers for their perceived unique flavor contributions to beer, despite not meeting contemporary agronomic and malting expectations. This study utilized crosses of the heirloom Maris Otter® and two contemporary genotypes to determine if “updated heirlooms” could be produced that would show improved agronomics and contemporary malt quality, while contributing uniquely to malt and beer sensory and chemical profiles. Using a recently established pipeline of malting; brewing; hot steep and beer sensory; and metabolomics to evaluate barley genotype contributions to malt and beer flavor, four experimental lines were compared to a control. The experimental lines were also assessed for their genomic contribution from their respective parents to further elucidate regions of the Maris Otter genome that may contribute to unique beer flavors. Results show improved agronomic outcomes relative to the heirloom parent and were comparable to the control. Malting quality met current recommendations. However, sensory properties attributable to the unique heirloom parent were not found. Further, chemical profiling did not explain the observed nuanced sensory differences, nor did it reveal unique metabolites not described by the sensory panels.

Evaluation of the Implementation Effect of the Ecological Compensation Policy in the Poyang Lake River Basin Based on Difference-in-Difference Method

Watershed environments play an important supporting role in sustainable high-quality economic development in China, but they have been deteriorating. In order to solve environmental problems in the Poyang Lake River Basin brought about by economic development, the Jiangxi Provincial Government promulgated relevant river basin protection policies in 2015. However, after several years of this policy, the specific effects of its implementation are a matter of general concern to the government and academic circles. After years of policy implementation, the implementation effect of the watershed ecological compensation policy needs to be evaluated. Based on 4248 observations from the Jiangxi and Hunan Provinces, we adopt the difference-in-difference method to analyze the impact of the ecological compensation policy on the Poyang Lake River Basin. The empirical results show that the ecological compensation policy has a significant effect on water-quality improvement. Water quality in the upstream area is better than that in the downstream area; areas with small administrative areas have a smaller population, which in turn leads to better water quality in the river basin; and the higher the per capita GDP, the worse the water quality. Our results highlight the need for the following policy improvements: ecological priority, customizing measures to local conditions, tracing the main body, and strengthening supervision.
