Collaborative Caching Strategy for RL-Based Content Downloading Algorithm in Clustered Vehicular Networks

With the explosive growth of content request services in the vehicle network, there is an urgent need to speed up the response process of content requests and reduce the backhaul burden on base stations. However, most traditional content caching strategies only consider the content popularity or cluster-based caching strategies individually, and the access paths are fixed. This paper proposes a collaborative caching strategy for reinforcement learning (RL) based content downloading. Specifically, the vehicles are first clustered by the K-means algorithm, and the content transmission distance is reduced by caching the content with high popularity in the cluster head. Then, according to the historical content request information, the long short-term memory is used to predict the popularity of content. The content with high popularity will be collaboratively cached in the base station and cluster heads. Finally, the content downloading problem can be described as a Markov decision process, using a deep reinforcement learning algorithm, Deep Q Network (DQN), to solve the target problem which is to minimize the weighted cost, including the downloading delay and failure cost. With the DQN algorithm, the cluster head can make the access decision for the content request. The proposed collaborative caching strategy for the RL-based content downloading algorithm can greatly reduce the response process and the burden at the base station. The simulation results show that the proposed RL-based method achieved outstanding performance to improve the access hit ratio and reduce the content downloading delay.

Characteristics of dried noodle analogue made from sorghum flour and rice flour added with konjac glucomannan

The high popularity of wheat-based food such as noodles in Indonesia has caused a large increase in wheat imports. Sorghum and rice are two local ingredients found in Indonesia; however, sorghum is not largely used as the main grain source, especially in noodle making. This research aimed to determine the effect of the ratio between sorghum flour and rice flour, and konjac glucomannan concentration on noodle analogue characteristics. Konjac glucomannan was added at different concentrations (3%, 4%, 5%) to different ratios of sorghum-rice flours (50:50, 25:75, 0:100). Results showed that the best formulation was a noodle analogue made with a 25:75 sorghum-rice flour ratio and 4% konjac glucomannan. The best-formulated noodle analogue had a higher moisture content (13.35±0.38%), higher fat, and higher carbohydrate (71.93±0.11%), but lower protein and ash content than the commercial wheat-based noodle. It also had a lower starch (60.43%) and dietary fibre content (10.34%), higher cooking loss (9.44±0.60%), and lower water absorption (176.45±4.86%) compared to commercial wheat-based noodle. In terms of textural and mechanical properties, the best-formulated noodle analogue had lower hardness, higher adhesiveness, lower springiness, lower cohesiveness, lower tensile strength, and lower elongation. However, the multiple comparison test showed that panellists perceived the best-formulated noodle analogue to be comparable to commercial wheat-based noodle, in terms of aroma, chewiness, hardness, and adhesiveness.

The Influence of NCT 127 as a Brand Ambassador and Brand Trust on Consumer Purchase Decisions at Blibli Online Shopping Site (Study on NCT 127 fans in Bandar Lampung)

Technological developments in Indonesia are currently growing rapidly and the presence of the internet has brought various conveniences and business opportunities for many people. The presence of the internet has enabled buying and selling activities to be carried out online, followed by the emergence of various online shopping or e-commerce sites in Indonesia, one of which is Blibli. Competition between e-commerce in Indonesia is getting tighter and the strategy used by Blibli in promoting their online shopping site is by taking advantage of the phenomenon that is currently being discussed, namely the Korean Wave phenomenon. Blibli takes advantage of this phenomenon by using K-Pop celebrity brand ambassadors as advertising stars and also building brand trust with consumers. NCT 127, a South Korean boy group with high popularity in Indonesia, was appointed as Blibli's brand ambassador. This study aims to determine the influence of NCT 127 as brand ambassadors and brand trust on consumer purchasing decisions on the online shopping site Blibli. The object of this research is NCT 127 fans in Bandar Lampung. This type of research is a quantitative research. This study used a purposive sampling method with a sample of 160 respondents and distributed via GoogleForm. This study uses multiple linear regression analysis and partial hypothesis testing (t-test). The results of the study show that partially there is a positive and significant influence between brand ambassador and brand trust variables on consumer purchasing decisions. The results obtained show that brand ambassadors have a positive and significant effect on consumer purchasing decisions with the highest contribution to the power dimension, and brand trust has a positive and significant effect on consumer purchasing decisions with the highest contribution to the trust dimension.

Dental aesthetic related popularity and peer pressure, a survey of adolescents in Pakistan.

Most research has focused on determining how popularity and peer pressure impact behaviours, rather than identifying a key feature such as dental aesthetics and studying its impacts in relation to popularity and peer pressure. A cross sectional study was conducted on a sample of 527 children from four schools located in Lahore, Pakistan. A 14-point questionnaire was developed, using existing measures of peer pressure, and popularity. The selected questions were modified to investigate the issues of dental aesthetics and integrated into the WHO oral health questionnaire for children. More than 50 % of the participants indicated popularity issues regarding dental aesthetics. 63.5 % of the responses indicated an influence of relatives and friends, whereas 38 % responses reported of harassment and bullying at schools. Regression analysis shows that the females were 1.99 times more likely to get comments from relative or friends about their teeth and 2.17 times more likely to be bullied or harassed at school due to their teethwhen compared to the males. Fathers with a higher education brought about higher popularity and peer pressure issues. Mothers with a higher education were lesslikely to cause popularity and peer pressure issues thanmothers with a lower education. Popularity and peer pressure were both significantly related to higher dental visitation. Popularity and peer pressure have a direct link to dental aesthetics in an individual and are impacted by gender, family relatives and parental influences. The area of popularity and peer pressure related to dental aesthetics canbe targeted in health education programs to empower children to adopt better oral health behaviours.

Heat vs. Health: Home Office under a Changing Climate

Stressors are especially widespread in urban agglomerations. Common themes of built environment interventions that support health and well-being are blue and green infrastructure, indoor and outdoor air quality, thermal comfort, access to natural lighting, and acoustics. Given the current megatrends of increasing summer temperatures and the high popularity of home offices, we aimed at modeling thermal comfort changes of people working at home in three Austrian cities (Vienna, Innsbruck, and Graz) during the next decades until 2090. We present findings based on (I) an inter-disciplinary literature search and (II) indoor and outdoor climate simulations for actual and future climate scenarios. Based on the results, we discuss the potential impacts for work and human health and well-being, and we suggest a framework for the home office in “post-COVID-19 Austria” that integrates social, ecological, and economic aspects. The results of our study indicate that, in future climate scenarios, overheating of the interior can no longer be prevented without active cooling measures and nature-based solutions. Recommendations on the adjustment of behavior under climate change, including greening, adequate ventilation, and cooling techniques, are thus urgently needed for employees who are working from home in order to maintain physical and mental health and wellbeing.

Geological heritage of Valerian Domger in the Middle Dnipro Region


 
 
 The paper looks at the significance of the scientfic geological studies of the famous geologist Valerian Domger and their importance for the development of geotourism in the region and Ukraine in general. We analyzed his works in the historical aspect from the beginning of his work as a geological practitioner to his becoming a reseracher of stratigraphy, paleontology and lithology of sedimentary deposits and geology of Precambrian formations of the Ukrainian Shield. We focused on the geological routes he took when travelling along the lines of railroad construction, including Orenburg, Ural, Mariupol (Donetsk) and Katerynoslav, analyzing the conclusions on the structures of those territories, as well as perspectives of finding natural resources in them. We characterized the most important routes V. Domger travelled when he was conducting geological surveys of the 47th sheet of the ten-versta map on the area of about 13 thou versts in Verhniodniprovsk and Katerynoslav powiets of Katerynoslav governorate, and also Kherson and Oleksandria powiets of Kherson governorate, which led to his most notable discoveries, namely the Nikopol deposits of manganese ores, a unique location of the Mandrykivka fossil fauna of the Upper Eocene and others. The achievements of V. Domger as a paleontologist were ahead of his time and – despite attempts of some notable researchers to refute the Late Eocene age of the Mandrykivka layers, the first identifications of the researcher were accurate and have been convingcingly confirmed by modernday studies. Despite their high popularity, the layers had no status in the stratigraphic resarch until 2000. The Commission of the Stratigraphic Classification and Nomenclature of National Stratigraphy Committee of Ukraine had examined the application from the author of this article regarding the Mandrykivka layers and recognized them as an individual stratigraphic unit (layers with a geographic name). For the first time, we noted the importance of the V. Domger’s routes and the outcrops he described when creating the data base of those geological heritage objects, their further inclusion to the Nature-Protection Fund of Ukraine and their use in the development of the region’s geotourism.
 
 

Expert knowledge guided manifold representation learning for magnetic resonance imaging-based glioma grading

Radiomics and deep learning have shown high popularity in automatic glioma grading. Radiomics extracts handcrafted features that quantitatively describe the expert knowledge of gliomas, and deep learning is powerful in extracting numerous learned features that facilitate the final classification. However, the performance of existing methods can still be improved as their complementary strengths haven’t been sufficiently investigated and integrated. Furthermore, the final prediction at the testing phase normally needs lesion maps which rely too much on the segmentation accuracy and could be troublesome. To address these challenges, we propose an expert knowledge guided manifold representation learning (ENROL) framework for accurate glioma grading without the reliance on segmentation maps during testing. Low-dimensional manifolds of the handcrafted features and learned features are constructed to mine the implicit relationship between radiomics and deep learning, and therefore to dig mutual consent representation for the glioma grades. With a specially designed manifold discrepancy measurement, the grading model can exploit the MRI data and expert knowledge more effectively and get rid of the requirement of lesion segmentation maps at the testing phase. The proposed framework is flexible regarding deep learning architectures to be utilized. Three different architectures have been evaluated on both single-sequence and multi-sequence MRI data. Results show that our framework can generate promising glioma grading performance.

Coffee Industry Analysis Based on Indicators: Evidence from Starbucks, Luckin and Nestle S.A.

Coffee is a favorite beverage worldwide, and its unique ability to keep people awake and energized has dramatically increased the sales volume. Its high popularity has led to a considerable investment market. Therefore, whether the coffee industry is worth investing in and how to evaluate it has become one of the most critical research classes today. Based on previous investigations, most investment evaluations of the coffee industry have focused on companies in the same geographic area. However, there is a research gap in whether the international coffee industry is worth investing in. On this basis, this study will analyze whether the coffee industry is worth investing in by collecting data on stock prices and financial reports as well as calculate WACC values and compare them using the data. According to the analysis, the WACC values of all three companies selected are generally high, which means that the investment risk is high. It is indicated that the coffee industry is not worth investing in nowadays because of the high risk and high cost. These results shed light on guiding further exploration of how to do the right choice of investment in the coffee market.

СТИЛІЗАЦІЯ УКРАЇНСЬКОГО НАРОДНОГО ТАНЦЮ В ПРОЦЕСІ ВИВЧЕННЯ ДИСЦИПЛІНИ «ТЕОРІЯ ТА ПРАКТИКА УКРАЇНСЬКОГО НАРОДНОГО ТАНЦЮ»

In the article, the author defines the main methods of stylization of Ukrainian folk dance. One of the most important forms of preservation and transmission of accumulated experience from one generation to another is the ability of Ukrainian folk dance to give birth and form new stage forms. The basis of any stylized number is folklore and ethnographic material, which conveys the entire atmosphere of the historical environment and reproduces the national flavor. The stylization of Ukrainian folk dance consists in the ability to competently combine modern acrobatic tricks and virtuosic movements with purely folk dance movements. Stylization makes it possible to reflect and convey the entire atmosphere of the national and historical environment, contributes to the strengthening of expressiveness in choreographic works. Ukrainian folk dance developed throughout the history of our people, accumulating new means of expression, because from its original ceremonial form, it underwent a thousand-year development, as a result of which it was enriched, complicated by new movements, accompanied by songs. Currently, Ukrainian folk dance occupies a significant place among the cultural heritage of our people, and its high popularity in Ukraine and abroad is explained by the wealth of plots and themes, humor, sincerity, cheerful character, etc. The presence of expressive everyday features, common and different, combined with technically virtuosic movements, gives Ukrainian folk dance its originality, originality and unique flavor. All structural elements of Ukrainian folk dance are subject to transformation: music, imagery, plot, vocabulary. All this is developed and developed by the choreographer, based on his own vision and creative individual style, the presence of thorough knowledge of classical, folk, modern, ballroom dance, knowledge of national choreographic features and culture of various peoples, etc. Ways of stylizing Ukrainian folk dance are built according to a clear algorithm. First, the ways of stylization, its stages and components are determined, and only then practical work on the choreographic piece begins. The methods of stylization used by the choreographer-producer to create a choreographic work based on Ukrainian folk dance must meet the interests of modern performers and spectators on the one hand, and on the other - preserve traditions, nurture personality through folk music and dance folklore.

The influence of relative popularity on negative fake reviews: A case study on restaurant reviews

Fake reviews are rising as online reviews become more prevalent. However, little is known about the mechanism underlying firms’ negative fake reviews. This study draws on signaling theory to analyze the effect of a firm’s relative popularity (vs. its competitors) on receiving negative fake reviews. Based on Yelp data for restaurants in New York City, we show that a restaurant’s relatively higher popularity over its competitors increases the number of negative fake reviews it receives. The positive impact of relative popularity on negative fake reviews is weakened by the restaurant’s reputation and competitors’ popularity. The effect is weaker for chain restaurants than for independent restaurants. This study examines the generation mechanism of negative fake reviews from a competition perspective and emphasizes relative popularity as a motivator behind such reviews. Implications for review system design and restaurant management are provided.

Popularity and effectiveness of modern ways of memorizing Chinese characters.

Due to the high and steady popularity of Chinese, a sufficient number of new techniques for studying Chinese characters are being developed today, many of which often represent updated versions of classical methods. We attempt to evaluate the ways of memorizing Chinese characters, to identify the difficulties faced by students. The article studies methods and techniques of memorizing Chinese characters used by students at a language university. We conducted a survey which revealed the techniques and methods of memorization that are used most frequently. When identifying the individual effectiveness of the use of techniques and methods by students, a discrepancy was found and analyzed between the use of certain methods and the assessment of students’ personal effectiveness. The authors also investigate the possibility of using a linguacultural approach to teaching Chinese hieroglyphic writing and predict the success of its application for the full assimilation of Chinese hieroglyphic writing and the acquisition of the cultural code of the country through hieroglyphs

The Fusion of Pop Songs and Chinese Elements: Zhou Shen's Traditional Elements Involved Performance in the Song Guangliang/Bright

Since the beginning of the 21st century, as China's national strength continues to grow, the Chinese people's national consciousness has increased. In order to make more young people pay attention to history and love traditional music, many musicians have incorporated Chinese-style elements into popular music with high popularity, which are reflected in the lyrics, singing voice, and orchestration of the songs throughout all parts of the songs. This study takes the song "Bright" composed by Qian Lei and sung by Zhou Shen as an example to analyze some "Chinese style" music. It is argued that the social function and entertainment functions of pop music will be increasingly enhanced, and the development also tends to diversify, and in the future, China's "Chinese-style" pop music will certainly have a bigger and better development.

The total number of complete compliance and partial compliance in the observation group was higher than that in the control group. Conclusion: The application of nursing intervention based on Nel Noddings care theory to the nursing of school-age asthmatic children can improve the self-management ability of children, promote the recovery of cough, wheezing and other symptoms, and is of great significance to improve the compliance and nursing effect of children, with high popularization and application value.

Artocarpus heterophyllus LAM. Stem Bark Inhibits Melanogenesis Through Regulation of ROS, cAMP and MAPK Pathways

Natural-based skin-lightening cosmeceutical products are attracting high popularity nowadays due to their relatively high bioavailability upon application. Artocarpus species have been highlighted with such potential, and our previous studies have reported that Artocarpus heterophyllusLam. stem bark extract exhibited a potent anti-melanogenic activity by reducing melanin content and inhibiting cellular tyrosinase activity in B16F10 melanoma cells. Hence, this study aimed to identify the bioactive fraction from A. heterophyllus Lam. stem bark and determine its anti-melanogenic mechanisms in B16F10 melanoma cells. Our results showed that a fraction (H-3) demonstrated the most pronounced anti-melanogenic effect at 12.00 µg/mL by reducing melanin content to 22.86 ± 2.90% and inhibiting cellular tyrosinase activity at treatment concentration 33-fold lower than kojic acid, without being cytotoxic against B16F10 melanoma cells. Moreover, treatment with H-3 for 24 and 48 h substantially scavenged intracellular reactive oxygen species (ROS) of hydrogen peroxide-challenged B16F10 melanoma cells by 1.8 and 4.4%, respectively. Based on the microarray profiling and qPCR analysis, H-3 downregulated Creb3l1, Creb3l2, Creb3l3, Mitf, Tyr, Tyrp1, and Dct genes in B16F10 melanoma cells, whereas the expression of Map3k20, Mapk14 (p38), and Foxo3 genes was markedly increased. Altogether, these results demonstrated that H-3 exhibited its anti-melanogenic activity in B16F10 melanoma cells through scavenging ROS and concurrent inhibition of the cAMP and activation of the p38/MAPK signaling pathways. These findings indicate that H-3 has the potential to be used as a skin lightening cosmeceutical agent in the treatment of skin hyperpigmentation.

"Have Fun" is the first funny experimental reality show in China launched by Zhejiang satellite TV in 2021. The communication advantages of this program are reflected in many aspects, but so far there is not much research literature on this program. This paper mainly uses the observation method to study and analyze the communication advantages of Have Fun from all aspects and extracts the reference significance of the program for reference.

Building WOM from Hedonic Experience of Social Media in the Field of Gastronomy

With the popularization of mobile phones and the Internet, users of social media platforms have formed the habit of surfing the Internet. Watching food programs has become one of the most important leisure activities. Food platforms on social media have low barriers to entry, and it is not easy to maintain high popularity, high performance, and high profits. In this context, it is extremely important to continue to gain word-of-mouth from fans. The objective of this study aims at investigating the relationships among hedonic experience, attachment, and word-of-mouth of social media in the field of gastronomy. Data were obtained through interviews and questionnaires. Through the analysis, this paper finds several ways to obtain the word-of-mouth of food programs, namely, hedonic experience - platform attachment - word-of-mouth. This study suggests that platform operators should provide relaxed and pleasant program content and atmosphere to meet users' needs of leisure and learning. For future researchers, future studies can try to add the comparison between utilitarianism and hedonism.

Correcting for the multiplicative and additive effects of measurement unreliability in meta-analysis of correlations.

As a powerful tool for synthesizing information from multiple studies, meta-analysis has gained high popularity in many disciplines. Conclusions stemming from meta-analyses are often used to direct theory development, calibrate sample size planning, and guide critical decision-making and policymaking. However, meta-analyses can be conflicted, misleading, and irreproducible. One of the reasons for meta-analyses to be misleading is the improper handling of measurement unreliability. We show that even when there is no publication bias, the current meta-analysis procedures would frequently detect nonexistent effects, and provide severely biased estimates and intervals with coverage rates far below the intended level. In this study, an effective approach to correcting for unreliability is proposed and evaluated via simulation studies. Its sensitivity to the violation of the homogeneous reliability and residual correlation assumption is also tested. The proposed method is illustrated using a real meta-analysis on the relationship between extroversion and subjective well-being. Substantial differences in meta-analytic results are observed between the proposed method and existing methods. Further, although not specifically designed for aggregating effect sizes with various measures, the proposed method can be used to fulfill the purpose. The study ends with discussions on the limitations and guidelines for implementing the proposed approach. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

Social goals and gains of adolescent bullying and aggression: A meta-analysis

There is a long-standing debate on the goals that underlie adolescent socially coercive behaviors, such as bullying, relational aggression, and instrumental aggression. Knowledge about these goals is critical for the development of effective interventions. Bridging evolutionary and social-cognitive perspectives, we propose and substantiate a Social Goals and Gains Model of Adolescent Bullying and Aggression. The model holds that adolescents who hold agentic goals (i.e., getting ahead of others), rather than communal goals (i.e., getting along with others), engage in more bullying and aggression. Engaging in bullying and aggression, in turn, may lead adolescents to gain popularity but lose likeability. To substantiate this model, we meta-analyzed data of 164,143 adolescents (age range: 8–20 years), from 148 independent samples, with Meta-Analytic Structural Equation Modeling (MASEM). Our results both support and refine our model. As hypothesized, adolescents’ agentic goals were associated with higher levels of bullying and aggression. Bullying and aggression, in turn, were associated with higher popularity but lower likeability. However, there was no significant association between adolescents’ communal goals and bullying or aggression. These findings suggest that socially coercive behaviors, such as bullying and aggression, can be fueled by agentic goals and potentially lead to gains in popularity but losses in likeability. This suggests that intervention programs could reduce bullying and aggression by changing the means through which adolescents pursue agentic goals.

3D Printed Hierarchical Porous Poly(ε-caprolactone) Scaffolds from Pickering High Internal Phase Emulsion Templating.

In the realm of biomaterials, particularly bone tissue engineering, there has been a great increase in interest in scaffolds with hierarchical porosity and customizable multifunctionality. Recently, the three-dimensional (3D) printing of biopolymer-based inks (solutions or emulsions) has gained high popularity for fabricating tissue engineering scaffolds, which optimally satisfies the desired properties and performances. Herein, therefore, we explore the fabrication of 3D printed hierarchical porous scaffolds of poly(ε-caprolactone) (PCL) using the water-in-oil (w/o) Pickering PCL high internal phase emulsions (HIPEs) as the ink in 3D printer. The Pickering PCL HIPEs stabilized using hydrophobically modified nanoclay comprised of aqueous poly(vinyl alcohol) (PVA) as the dispersed phase. Rheological measurements suggested the shear thinning behavior of Pickering HIPEs having a dispersed droplet diameter of 3-25 μm. The pore morphology resembling the natural extracellular matrix and the mechanical properties of scaffolds were customized by tuning the emulsion composition and 3D printing parameters. In vitro biomineralization and drug release studies proved the scaffolds' potential in developing the apatite-rich bioactive interphase and controlled drug delivery, respectively. During in vitro osteoblast (MG63) growth experiments for up to 7 days, good adhesion and proliferation on PCL scaffolds confirmed their cytocompatibility, assessed by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide (MTT) analysis. This study suggests that the assembly of HIPE templates and 3D printing is a promising approach to creating hierarchical porous scaffolds potentially suitable for bone tissue engineering and can be stretched to other biopolymers as well.
