Image inpainting is a process of reconstructing an incomplete image from the available information in a visually plausible way. In the proposed framework, existing image inpainting methods are classified in a new perspective. The information which is referred to, while reconstructing an image, is a critical factor of inpainting algorithms. Source of this information can be host image itself or an external source. The proposed framework broadly classifies inpainting algorithms into introspective and extrospective categories based on the source of information. Various parameters influencing the algorithms under these categories are identified in the proposed framework. A comprehensive list of all publicly available datasets along with the references are also summarized. Additionally, an in-depth analysis of the results obtained with the surveyed techniques is performed based on quantitative and qualitative parameters. The proposed framework aids the user in identifying the most suitable algorithm for various inpainting scenarios.

Reliance on social media as a source of information has lead to several challenges, including the limitation of sources to viewers’ preferences and desires, also known as filter bubbles. The formation of filter bubbles is a known risk to democracy. It can bring negative consequences like polarisation of the society, users’ tendency to extremist viewpoints and the proliferation of fake news. Previous studies have focused on specific aspects and paid less attention to a holistic approach for eliminating the notion. The current study, however, aims to propose a model for an integrated tool that assists users in avoiding filter bubbles in social networks. To this end, a systematic literature review has been undertaken, and initially, 571 papers in six top-ranked scientific databases have been identified. After excluding irrelevant studies and performing an in-depth analysis of the remaining papers, a classification of research studies is proposed. This classification is then used to introduce an overall architecture for an integrated tool that synthesises all previous studies and offers new features for avoiding filter bubbles. The study explains the components and features of the proposed architecture and concludes with a list of implications for the recommended tool.

Soil fertility determines a plant's development process that guarantees food sufficiency and the security of lives and properties through bumper harvests. The fertility of soil varies according to regions, thereby determining the type of crops to be planted. However, there is no repository or any source of information about the fertility of the soil in any region in Nigeria especially the Northwest of the country. The only available information is soil samples with their attributes which gives little or no information to the average farmer. This has affected crop yield in all the regions, more particularly the Northwest region, thus resulting in lower food production.  Therefore, this study is aimed at classifying soil data based on their fertility in the Northwest region of Nigeria using R programming. Data were obtained from the department of soil science from Ahmadu Bello University, Zaria. The data contain 400 soil samples containing 13 attributes. The relationship between soil attributes was observed based on the data. K-means clustering algorithm was employed in analyzing soil fertility clusters. Four clusters were identified with cluster 1 having the highest fertility, followed by 2 and the fertility decreases with an increasing number of clusters. The identification of the most fertile clusters will guide farmers on where best to concentrate on when planting their crops in order to improve productivity and crop yield.

AbstractExosomes are major contributors in cell to cell communication due to their ability to transfer biological material such as protein, RNA, DNA, and miRNA. Additionally, they play a role in tumor initiation, promotion, and progression, and recently, they have emerged as a potential source of information on tumor detection and may be useful as diagnostic, prognostic, and predictive tools. This review focuses on exosomes from lung cancer with a focus on EGFR mutations. Here, we outline the role of exosomes and their functional effect in carcinogenesis, tumor progression, and metastasis. Finally, we discuss the possibility of exosomes as novel biomarkers in early detection, diagnosis, assessment of prognosis, and prediction of therapeutic response in EGFR-mutated lung cancer.

AbstractThe rapid and massive adoption of mobile money transfer (MMT) services in East Africa, particularly in Kenya, stands in stark contrast to historically low use of formal financial systems on the continent. Its ‘fertile grounds’ therefore require in-depth analysis to understand the implications for African financial systems. This paper argues for the need to examine the underlying conceptual environment that enables low income and poor people's MMT adoption. It innovatively combines anthropological with ethnolinguistic analytical approaches to distinguish two repertoires around resource exchange. First, is a relational financial repertoire where relationships are developed and consolidated to create support and ‘upliftment’. A contrasting resource-focused repertoire is more like that of the formal financial sector. Identifying the conceptual features of relationality, the study offers a new perspective on the adoption and use of MMT in Africa and highlights the potential for disjunctures with policy efforts to increase financial inclusion.

Interest from academics, policy–makers and practitioners in eco-innovation has increased as it enables the optimization of the use of natural resources improving competitiveness and it provides a conceptual framework for corporate sustainability. In this context, this paper provides an in-depth analysis and a wide classification of the specific indicators for the integrated measurement of eco-innovation projects in business from a resource-based view (RBV). The specific metrics were tested to measure the economic-financial and environmental resources and capabilities applied by five Spanish firms to eco-innovation projects, selected as case studies.

Abstract The following article argues that fictional texts can be distinguished from non-fictional texts in a prototypical way, even if the concept of the fictional cannot be defined in classical terms. In order to be able to characterize fictional texts, semantic, pragmatic, and reader-conditioned factors have to be taken into account. With reference to Frege, Searle, and Gabriel, the article recalls some proposals for how we might define fictional speech. Underscored in particular is the role of reception for the classification of a text as fictional. I make the case, from a philosophical perspective, for the view that fictional texts represent worlds that do not exist even though these worlds obviously can, and de facto do, contain many elements that are familiar to us from our world. I call these worlds reading worlds and explain the relationship between reading worlds and the life world of readers. This will help support the argument that the encounter with fictional literature can invoke real feelings and that such feelings are by no means irrational, as some defenders of the paradox of fiction would like us to believe. It is the exemplary character of fictional texts that enables us to make connections between the reading worlds and the life world. First and foremost, the article discusses the question of what it is that readers’ feelings are in fact related to. The widespread view that these feelings are primarily related to the characters or events represented in a text proves too simple and needs to be amended. Whoever is sad because of the fate of a fictive character imagines how he or she would fare if in a similar situation. He or she would feel sad as it relates to his or her own situation. And it is this feeling on behalf of one’s self that is the presupposition of sympathy for a fictive character. While reading, the feelings related to fictive characters and content are intertwined with the feelings related to one’s own personal concerns. The feelings one has on his or her own behalf belong to the feelings related to fictive characters; the former are the presupposition of the latter. If we look at the matter in this way, a new perspective opens up on the paradox of fiction. Generally speaking, the discussion surrounding the paradox of fiction is really about readers’ feelings as they relate to fictive persons or content. The question is then how it is possible to have them, since fictive persons and situations do not exist. If, however, the emotional relation to fictive characters and situations is conceived of as mediated by the feelings one has on one’s own behalf, the paradox loses its confusing effect since the imputation of existence no longer plays a central role. Instead, the conjecture that the events in a fictional story could have happened in one’s own life is important. The reader imagines that a story had or could have happened to him or herself. Readers are therefore often moved by a fictive event because they relate what happened in a story to themselves. They have understood the literary event as something that is humanly relevant in a general sense, and they see it as exemplary for human life as such. This is the decisive factor which gives rise to a connection between fiction and reality. The emotional relation to fictive characters happens on the basis of emotions that we would have for our own sake were we confronted with an occurrence like the one being narrated. What happens to the characters in a fictional text could also happen to readers. This is enough to stimulate corresponding feelings. We neither have to assume the existence of fictive characters nor do we have to suspend our knowledge about the fictive character of events or take part in a game of make-believe. But we do have to be able to regard the events in a fictional text as exemplary for human life. The representation of an occurrence in a novel exhibits a number of commonalities with the representation of something that could happen in the future. Consciousness of the future would seem to be a presupposition for developing feelings for something that is only represented. This requires the power of imagination. One has to be able to imagine what is happening to the characters involved in the occurrence being narrated in a fictional text, ›empathize‹ with them, and ultimately one has to be able to imagine that he or she could also be entangled in the same event and what it would be like. Without the use of these skills, it would remain a mystery how reading a fictional text can lead to feelings and how fictive occurrences can be related to reality. The fate of Anna Karenina can move us, we can sympathize with her, because reading the novel confronts us with possibilities that could affect our own lives. The imagination of such possibilities stimulates feelings that are related to us and to our lives. On that basis, we can participate in the fate of fictive characters without having to imagine that they really exist.

The study aims to explore the entrepreneurship education of overseas Chinese returnees with the swindler syndrome through psychological resilience. First, a questionnaire survey is conducted to analyze the current situations of entrepreneurship education of overseas Chinses returnees and college students, and it is found that the entrepreneurship education received by overseas Chinese returnees is more advanced and perfect than that by domestic students, which makes overseas Chinese returnees have the ability to solve the problems in the process of entrepreneurship, realizing their entrepreneurial dream. However, the emergence of swindler syndrome changes the self-awareness and psychology of these returnees, which is improved through appropriate entrepreneurship education under resilience analysis. The results show that entrepreneurial resilience and entrepreneurial optimism covered by psychological resilience have a significant positive impact on entrepreneurial intention, indicating that entrepreneurial resilience and entrepreneurial optimism can enhance individual’s entrepreneurial intention. The scores of the subjects with the experience of studying abroad are higher than those without such experience, indicating that overseas Chinese returnees have stronger resilience and more optimistic attitudes in the face of difficulties and setbacks, which provides a new perspective for in-depth analysis of Chinese returnees’ entrepreneurship education and promotes the development of entrepreneurship education in colleges and universities in China.

AbstractSince 2009, numerous tools have been developed to detect structural variants (SVs) using short read technologies. Insertions >50 bp are one of the hardest type to discover and are drastically underrepresented in gold standard variant callsets. The advent of long read technologies has completely changed the situation. In 2019, two independent cross technologies studies have published the most complete variant callsets with sequence resolved insertions in human individuals. Among the reported insertions, only 17 to 37% could be discovered with short-read based tools. In this work, we performed an in-depth analysis of these unprecedented insertion callsets in order to investigate the causes of such failures. We have first established a precise classification of insertion variants according to four layers of characterization: the nature and size of the inserted sequence, the genomic context of the insertion site and the breakpoint junction complexity. Because these levels are intertwined, we then used simulations to characterize the impact of each complexity factor on the recall of several SV callers. Simulations showed that the most impacting factor was the insertion type rather than the genomic context, with various difficulties being handled differently among the tested SV callers, and they highlighted the lack of sequence resolution for most insertion calls. Our results explain the low recall by pointing out several difficulty factors among the observed insertion features and provide avenues for improving SV caller algorithms and their [email protected]

<div>This thesis researches the translation of Chinese culture-specific items in <em>Red Poppies</em> from the perspectives of Eco-translatology. Eco-translatology, which was put forward by Chinese scholar Hu Gengshen, adopts some concepts of ecology in translatology and provides a new perspective for translation study and practice. <em>Red Poppies</em> is a novel by Alai whose contents covers a wide range of Tibetan culture and history, which is praised as Tibetan encyclopedia. On one hand, the study focuses on the definition and features of culture-specific items, and their classification of in Red</div><div>Poppies. Based on Nida’s classification of five categories of sub-culture, those culture-specific items are classified into five groups, namely linguistic culture-specific items, material culture-specific items, ecological culture--specific items, social culture-specific items and religious culture-specific items. On the other hand, this thesis explores how Goldblatt deal with those culture-specific items from the perspective of three-dimension transformation in eco-translatology, and it finds translator adopts a combination of foreignization strategy and domestication strategy, and the former plays a dominating role. Besides, various translation methods are adopted such as free translation, transliteration, transliteration plus annotation, and amplification and so on.</div>
