Blind Image

Blind forensic-investigation in a digital image is a new research direction in image security. It aims to discover the altered image content without any embedded security scheme. Block and key point based methods are the two dispensation options in blind image forensic investigation. Both the techniques exhibit the best performance to reveal the tampered image. The success of these methods is limited due to computational complexity and detection accuracy against various image distortions and geometric transformation operations. This article introduces different blind image tampering methods and introduces a robust image forensic investigation method to determine the copy-move tampered image by means of fuzzy logic approach. Empirical outcomes facilitate that the projected scheme effectively classifies copy-move type of forensic images as well as blurred tampered image. Overall detection accuracy of this method is high over the existing methods.

Post Transcriptional Regulation

AbstractOsteosarcoma (OS) is the most common primary malignant tumor of the skeletal system in the clinic. It mainly occurs in adolescent patients and the pathogenesis of the disease is very complicated. The distant metastasis may occur in the early stage, and the prognosis is poor. MicroRNAs (miRNAs) are non-coding RNAs of about 18–25 nt in length that are involved in post-transcriptional regulation of genes. miRNAs can regulate target gene expression by promoting the degradation of target mRNAs or inhibiting the translation process, thereby the proliferation of OS cells can be inhibited and the apoptosis can be promoted; in this way, miRNAs can affect the metabolism of OS cells and can also participate in the occurrence, invasion, metastasis, and recurrence of OS. Some miRNAs have already been found to be closely related to the prognosis of patients with OS. Unlike other reviews, this review summarizes the miRNA molecules closely related to the development, diagnosis, prognosis, and treatment of OS in recent years. The expression and influence of miRNA molecule on OS were discussed in detail, and the related research progress was summarized to provide a new research direction for early diagnosis and treatment of OS.

Ozone Disinfection

Secondary effluent from WWTPS still contains a large number of microorganisms, therefore, disinfection is essential. There are many disadvantages in using traditional disinfection methods, so the combination of disinfection techniques is a new research direction. Ozone combined with ultrasound is one of them. In this experiment, the inactivation of the total coli forms, color removal and UV254 removal of secondary effluent by a combination of ultrasonic (frequency20 kHz; power100W) and ozone disinfection was investigated. The results show that the effect of the synergistic action of 30s US and ozone disinfection is superior to the effect of individual ozone disinfection. After 15min synergistic disinfection, the total coli forms inactivation rate is up to 99.9%, simultaneously color removal rate to 80% and UV254 removal rate to 52%. Compared with individual ozone disinfection, reaction time was reduced by 5 min.

In variant design, the proliferation of bills of materials makes it difficult for designers to find previous designs that would aid in completing a new design task. This research presents a novel, data mining approach to forming generic bills of materials (GBOMs), entities that represent the different variants in a product family and facilitate the search for similar designs and configuration of new variants. The technical difficulties include: (i) developing families or categories for products, assemblies, and component parts; (ii) generalizing purchased parts and quantifying their similarity; (iii) performing tree union; and (iv) establishing design constraints. These challenges are met through data mining methods such as text and tree mining, a new tree union procedure, and embodying the GBOM and design constraints in constrained XML. The paper concludes with a case study, using data from a manufacturer of nurse call devices, and identifies a new research direction for data mining motivated by the domains of engineering design and information.

Proverbs are important data depicting the traditional culture of each nation. Vietnamese proverbs, dated thousands of years ago, are an immense valuable treasure of experience which the Vietnamese people desire to pass to the younger generations. This paper aims to explore the unique and diversified world of intelligence and spirits of the Vietnamese through a condensed and special literary genre, as well as a traditional value of the nation (Nguyen Xuan Kinh 2013, Tran Ngoc Them 1996, Le Chi Que and Ngo Thi Thanh Quy 2014). Through an interdisciplinary approach, from an anthropological point of view, approaching proverbs we will open up a vast treasure of knowledge and culture of all Vietnamese generations. The study has examined over 16,000 Vietnamese proverbs and analysed three groups expressing Vietnamese people’s behaviors toward nature, society and their selves, and compared them with English and Japanese proverbs. The research has attempted to explore the beauty of Vietnamese language, cultural values and the souls and personalities of Vietnam. Approaching Vietnamese proverbs under the interdisciplinary perspective of language, culture and literature is a new research direction in the field of Social Sciences and Humanity in Vietnam. From these viewpoints, it is seen that proverbs have remarkably contributed to the language and culture of Vietnam as well as and constructed to the practice of language use in everyday life which is imaginary, meaningful and effective in communication. Furthermore, the study seeks to inspire the Vietnamese youth’s pride in national identity and to encourage their preservation and promotion for traditional values of the nation in the context of integration and globalisation. In the meantime, it would be favourable to introduce and market the beauty of Vietnamese language, culture and people to the world, encouraging the speakers of other languages to study, explore and understand Vietnam.

Abstract Background: Gastric cancer (GC) is one of the most common malignancies, and more and more evdiences show that the pathogenesis is regulated by various miRNAs.In this study, we investigated the role of miR-875 in GC. Methods:The expression of miR-875-5p was detected in human GC specimens and cell lines by miRNA RT-PCR. The effect of miR-875-5p on GC proliferation was determined by CCK-8 proliferation assay and EDU assay. Migration and invasion were examined by transwell migration and invasion assay and wound healing assay. The interaction between miR-875-5p and its target gene USF2 was verified by a dual luciferase reporter assay. The effects of miR-875-5p in vivo were studied in xenograft nude mice models.Related proteins were detected by Western blot.Results:The results showed that miR-875-5p inhibited the proliferation, migration and invasion of gastric cancer cells in vitro, and inhibited tumorigenesis in vivo. USF2 proved to be a direct target of miR-875-5p. Knockdown of USF2 partially counteracts the effects of miR-875-5p inhibitors.Overexpression of miR-875-5p can inhibit proliferation, migration, and invasion through the TGF-β signaling pathway by down-regulation of USF2 in GC, providing a new research direction for the diagnosis and targeted therapy of GC.Conclusions: MiR-875-5pcan inhibited the progression of GC by directly targeting USF2 and negatively regulating TGF-β signaling pathway.In the future, miR-875-5p is expected to be used as a potential therapeutic target for GC therapy.

Research in code-switching, undertaken against the backdrop of very negative attitudes towards the concurrent use of two or more languages within the same conversation, has traditionally been geared towards rehabilitating this form of language use. From being seen as a random phenomenon reflecting the user’s lack of competence, code-switching is currently seen as sign of an advanced level of competence in the languages involved and as serving different interactional functions. However, as a result of its success, the research tradition now faces an entirely new challenge: Where to from here? How can research in code-switching continue to be relevant and interesting now it has largely achieved its original purpose? This book has argued that, in order to overcome this challenge, the notion of bilingualism itself must be redefined. Bilingualism must be seen as consisting of diverse interactional practices and be investigated as such. This book has made the case for this new approach, outlined a methodology for investigating bilingualism as interactional practices and illustrated it by means of three case studies. This concluding chapter wraps up the argument and invites other researchers to contribute to this new research direction.
