Multimodal Recommender Systems: A Survey

The recommender system (RS) has been an integral toolkit of online services. They are equipped with various deep learning techniques to model user preference based on identifier and attribute information. With the emergence of multimedia services, such as short videos, news and etc. , understanding these contents while recommending becomes critical. Besides, multimodal features are also helpful in alleviating the problem of data sparsity in RS. Thus, M ultimodal R ecommender S ystem (MRS) has attracted much attention from both academia and industry recently. In this paper, we will give a comprehensive survey of the MRS models, mainly from technical views. First, we conclude the general procedures and major challenges for MRS. Then, we introduce the existing MRS models according to four categories, i.e., Modality Encoder , Feature Interaction , Feature Enhancement and Model Optimization . Besides, to make it convenient for those who want to research this field, we also summarize the dataset and code resources. Finally, we discuss some promising future directions of MRS and conclude this paper. To access more details of the surveyed papers, such as implementation code, we open source a repository.

Cyber Security and Securing Subjective Patient Quality Engagements in Medical Applications: AI and Vulnerabilities

Public policy arguments about the appropriate valuation of life in public policy have generally moved on from accounting resource costs to recognizing and including revealed preference valuations. In medical and public health, the valuation of the “quality” life experience over time (a very different concept) has focused on equivalents to an unconstrained life experience. The user perspective on these valuations is largely missing and has substantial implications for both individuals and organizations. As these summary measures are fundamental to current triage and assessment processes, they have considerable importance for individuals. Recognizing this, requires consideration of the number of different channels that can bias the assessment of individuals in specific circumstances when AI support is used, as a wide range of inferences from diverse data are then brought to bear and amplifies health data security scope and importance. These intermediate aggregate channel security vulnerabilities have not previously been highlighted, in spite of the importance attached to these summary measures in public health. The collision of totally individualized assumed impacts and end-user consequences are amplified rapidly by AI methods in support of decisions, and the security and privacy-if any is left—of individual medical AND life data are thus jointly at cyber risk. This article is a preliminary—largely gedanken- exploration of the results of combining these very different technical views and perspectives, and is intended to stimulate work that takes all these aspects into account.

Integrating technical and political views for a sustainable European Distributed Infrastructure on Population Health

BackgroundNon-Communicable diseases (NCD) are the main contributors to mortality and burden of disease. There is no infrastructure in Europe that could provide health information (HI) on Public Health monitoring and Health Systems Performance (HSP) for research and evidence-informed decision-making. Moreover, there was no EU and European Economic Area Member States (EU/EEA MSs) general consensus, on developing this initiative and guarantee its sustainability. The aim of this study is to analyze the integration of technical and political views made by the Joint Action on Health Information (InfAct; Information for Action) and the results obtained from those activities, in terms of advice and national and institutional support to develop an integrated and sustainable European Distributed Infrastructure on Population Health (DIPoH) for research and evidence-informed policy-making.MethodsInfAct established two main boards, the Technical Dialogues (TDs) and the Assembly of Members (AoM), to provide a platform for discussion with EU/EEA MSs to establish a sustainable infrastructure for HI: 1) The TDs were composed by national technical experts (NTE) with the aim to discuss and provide feedback about scientific aspects, feasibility and EU-added value of the infrastructure proposed by InfAct. 2) The AoM gathered country representatives from Ministries of Health and Research at the highest political level, with the aim of providing policy-oriented advice for the future political acceptance, support, implementation, and development of InfAct’s outcomes including DIPoH.The documentation provided for the meetings consisted in Fact-Sheets, where the main results, new methods and proposals were clearly exposed for discussion and assessment; altogether with more extended information of the DIPoH. The documentation was provided to national representatives within one more before each TD and AoM meeting.The Agenda and methodological approaches for each TD and AoM meeting consisted in the presentations of the InfAct outcomes extending the information provided in the Fact-Sheets; followed by a non-structured interaction, exchange of information, discussion and suggestions by the MSs representatives.The outcomes of the non-structured discussions were collected in Minutes of the TD and AoM meetings, and the final version was obtained with the consensus of all participants. Additionally, structured letters of political support were provided to the AoM representatives, for them to consider providing their MS written support for DIPoH.ResultsNTE, within the TDs, considered that DIPoH was useful for technical mutual learning and cooperation among and within countries; although they considered that the technical feasibility to uptake InfAct deliverables at the national and EU level was complex. The AoM focused on political support, resources, and expected MSs returns. The AoM representatives agreed in the interest of setting up an integrated and sustainable HI infrastructure and they considered DIPoH to be well-articulated and defined; although, some of them, expressed some barriers for providing DIPoH political support. The AoM representatives stated that the AoM is the most suitable way to inform EU MSs/ACs about future advances of DIPoH. Both boards provided valuable feedback to develop this infrastructure. Eleven countries and sixteen institutions supported the proposal, either by letters of political support or by signing the Memorandum of Understandings (MoU) and three countries, additionally, provided expression of financial commitment, for DIPoH to be added to the ESFRI 2021 roadmap.ConclusionsTDs and AoM were key forums to develop, advise, advocate and provide support for a sustainable European research infrastructure for Population Health.

Core and safety design for France–Japan common concept on sodium-cooled fast reactor

France (CEA and FRAMATOME) and Japan (JAEA, MFBR, and MHI) teams have carried out collaborative works to have common technical views regarding a sodium-cooled fast reactor (SFR) concept. This paper mainly describes the capabilities of ASTRID 600 to demonstrate SFR technologies of both countries. Japan has studied the feasibility of an enhanced high burnup low-void effect (CFV) core and fuel using oxide dispersion-strengthened steel cladding in ASTRID 600, considering Japan’s target for core performance. The neutronics design of the core has satisfied most required design targets and conditions. Regarding passive shutdown capabilities, Japan team has performed a preliminary numerical analysis for ASTRID 600 using a complementary safety device (CSD), called a self-actuated shutdown system (SASS), one of the safest approaches in Japan. Japan’s team used the SASS in place of the hydraulically suspended absorber rod, called RBH, one of the safest approaches of France, to investigate the potential of the SASS as a design measure common to the countries. The preliminary analysis has shown that the SASS can satisfy the countries’ main requirements. This study has also revealed that the mitigation measures of ASTRID 600 against a severe accident are promising to achieve in-vessel retention for both countries.

Stock Price Prediction Using Datamining With Novel Computing Approach

Foreseeing financial exchange is consistently a difficult work. As an ever increasing number of individuals are associated with exchanging , its consistently an idealistic conduct to predict about the future price. By means of predicting the future stock price, experts and analysts in the stock field can buy or sell accordingly. In order to predict the stock value, financial specialists utilized crucial examination, specialized investigation and innovative investigation. Different strategies, for example, utilizing stock pointers additionally end up being a value a few. Yet, even though there are many techniques available the result of stock prediction is always a random one because of it adhoc nature. The experts in this field can also track the various information channel in order to increase their predicting performance. The previous work consolidates more on the result rather than the methods used. In this paper, we proposed a novel technique which uses the technological methods with that of the technical views and the changing news information’s about the stock. We implemented fuzzy rational algorithm with that of the hybrid neural network in conjunction with the k nearest matching points. The optimization techniques used here are the combination of the soft computing methods.

Luminescent Nanomaterials (I).

From molecular probes, also known as fluorophores (typically emitting a longer wavelength than the absorbing wavelength), to inorganic nanoparticles, various light-emitting materials have been actively studied and developed for various applications in life science owing to their superior imaging and sensing ability. Especially after the breakthrough development of quantum dots (QDs), studies have pursuedthe development of the optical properties and biological applications of luminescent inorganic nanoparticles such as upconversion nanoparticles (UCNPs), metal nanoclusters, carbon dots, and so on. In this review, we first provide a brief explanation about the theoretical background and traditional concepts of molecular fluorophores. Then,currently developed luminescent nanoparticles are described as sensing and imaging platforms from general aspects to technical views.

Volker Müller & Co.: Electronic Music and Sound Engineering at the WDR

This article is about Volker Müller (b. 1942), a German sound engineer who worked at the WDR Studio for Electronic Music in Cologne for approximately 30 years. I look into Müller’s training as a sound engineer at the Düsseldorf Sound Engineering College and his activities at the WDR studio as a way of expanding on West German post-war state’s building and cybernetics pedagogy. By complicating merely technical, operational and mechanistic views of the sound engineer’s role in the studio, I argue that Volker Müller embodied a particular culture of sound engineering and certain political and artistic utopias that resonate with broader political, economic, and pedagogical structures developed in the context of Cold War.

A Conceptual Framework on Defining Businesses Strategy for Artificial Intelligence

The technological developments on artificial intelligence (AI) are going to diffuse in all scales of firms in different industries. AI is increasingly used in diverse business functions, including marketing, customer service, cost reduction, and product improvement. Although there exists a large number of studies on AI, those focusing on the businesses are rather rare, and there is no holistic conceptual framework that brings the information on defining AI business strategy. The aim of this paper is to develop a conceptual framework on defining AI business strategy through a systematic literature review (SLR) of research conducted between 2015 and 2019. Consolidating business and technical views of AI, the paper discusses the major elements of AI in business like abilities and limitations of AI, economics and AI, business functions and AI, workforce, industries and AI, and regulations and ethics of AI on defining AI business strategy.

Security of Cryptocurrencies in blockchain technology: State-of-art, challenges and future prospects

In contemporary era of technologies, blockchain has acquired tremendous attention from various domains. It has wide spectrum of applications ranging from finance to social services and has greatly influenced the emerging business world. Since, blockchain technology is getting embedded in the e-commerce services, the cryptocurrencies are gaining huge prevalence. Bitcoin and ethereum are few such crypto currencies, which have utilized decentralized nature of blockchain. Blockchain can be considered as a distributed database system containing immutable ledgers, which are prone to attack by malicious users. Although, from the initial digital currency to the present smart contract, the utilities of blockchain have been harnessed, the innovative technology has to rely on cryptography for its security. There are several reports, which emphases on the vulnerabilities and security of blockchain, however, there is a lack of a comprehensive and methodical survey in both application and technical views.

Existing emerging vulnerabilities of blockchain related to the recent attacks on bitcoin and etherum is also presented along with the defensive methodologies and future trends in blockchain.

Design of Radial Artery Pulse Sensor System for Ayurveda Disease Diagnosis

In today’s modern world everyone will be suffering from one or another disease and to know it all doctors suggest to undergo some scanning like x-ray, MRI, city scan and some blood checkups to confirm one’s health issue with his prediction. In ancient days there was no scanning and checkup instead people believed in physicians, who use treat the unhealthy persons with knowledge of medicine known as ayurveda in India and Traditional Chinese Medicine (TCM) in china. In ayurveda there are eight methods to diagnose the health status and one of it is nadi pareeksha, where nadi vaidya feels the three nadi signals vata, pitta and kapha at the wrist of a person and by feeling the palpation of these signals he predicts the health status of a person. As now a day’s everyone has adopted costly and complex foreign medicine, which only tries to cure the present health issue of a subject has got hundreds of side effects, so in order to overcome this we need to follow the ayurveda practitioner. Ayurveda require a very experienced person who rarely seen in modern world, so we are trying to bring their ideas in some technical views. In this project, a non-invasive methodology is implemented to know health issue of a person and an attempt is made to bring back the ayurvedic knowledge. Where nadi signals of a subject are acquired and calculated each signal mean and peak values, which are different for different health issues and stored in a database. The incoming new subject signals mean and peak values are computed and compared with values stored in data base and then the system reports the health status of a subject.

Small states’ marginality constellations and the challenges to the Europeanisation of the Western Balkans in the last decade

By focusing on the Western Balkans, this paper asks two questions: first, how small states that are both EU members and candidates for membership understand their role within this normatively powered order and, second, what their roles and agency mean for the order they are socialised into via democratic norms. The notions of hierarchies and orders are conceptualised in this paper as processes of norm diffusion and understood within the socialisation of democratic norms, which, according to the literature, can be institutionalised, rejected, or modified locally. First, I argue that such measurements can help us understand how the EU’s practices shape the broader understanding of its actorness in normative and strategic terms toward the Western Balkans. Second, I scrutinise national strategies related to the processes of state-building, security, economy, and society to demonstrate how Serbia and Croatia present their agency as supporting and affirming of the prevalent conception of order in norm localisation, or being more critical of it in the process of localised norm contestation. Third, the effects of EU approaches that provide more tactical and technical views of Europeanisation, rather than (a strategic) full thrust on enlargement, are discussed in the conclusion by bringing the comparative insights together and parsing them by means of the shelter theory for small states.

Digital Tools and Technical Views: The Intersection of Digital Art History and Technical Art History in a Digital Archive on the Painting Technique of Caravaggio and His Followers

Digital art history is currently moving into a new phase. As a result of the ongoing digitization of artifacts and the creation of large digital repositories that bring together literary sources, images, as well as historical and technical data, new perspectives point to data mining and data/image processing. This article reviews some of the main data and image bases that deal with technical and material studies on works of art. The work-in-progress, Technical Data/Image Base on Caravaggio and His Followers, of the Max Planck Institut für Kunstgeschichte/Bibliotheca Hertziana (Rome, Italy) is presented within a historical and theoretical framework, describing the establishment of technical research in art history and the role played as early as 1930 by the International Conference for the Study of Scientific Methods in the Examination and Conservation of Artworks (Rome). The state of the art of technical research on the Italian painter Michelangelo Merisi, Il Caravaggio (1571–1610) and its critical issues are also sketched out, and the nature of the scientific information provided by digital multispectral imaging is considered within a brief review of the history of technical images.

Their proximity, both in methodological and instrumental terms, is shown. The system of views on the process of management of sustainable development of the region is formed, considered as a socio-ecological and economic system. Terms, principles and tools are generalized and formulated for the management process, including the justification for the use of economic and mathematical apparatus and information technology tools for its optimization.

INTERNATIONAL CONFERENCE ON HARMONISATION: AN OVERVIEW

The International Conference on Harmonisation (ICH) is a project that makes together the regulatory bodies of Europe, Japan and the United States and professionals from the pharmaceutical domain in the three areas to discuss scientific and technical views of medicinal product registration. The one aim of ICH is to reduce the need to repeat the testing carried out during the R &D of new Pharmaceuticals by suggesting ways to attain greater harmonisation in the interpretation and application of technical guidelines and requirements for Pharmaceuticals registration. Harmonisation would lead to a more frugal use of human, animal and material resources, and the evacuation of unnecessary time lag in the global development and availability of new Pharmaceuticals while maintaining safeguards on quality, safety, and efficacy, and regulatory duties to protect public health.

A Practical Map Needs Direct Visual Odometry

Visual odometry (VO) is the process of estimating the ego-motion of an agent sequentially (e.g. vehicle, human, and robot) using only the input of single or multiple cameras attached to it. VO plays an important role in Simultaneous Localization and Mapping (SLAM), which has been widely applied in many fields. The development of VO would greatly promote the transition of visual mapping and navigation to the industry. This paper focuses on direct methods and aims to summarize recent direct algorithms from technical views. Image representation and frame matching strategy are the two key components of VO. This paper is organized based on these two aspects. A qualitative analysis of existing work is then presented. This paper simultaneously serves as a position and tutorial paper.

Corporate Law Reform and the Political Environment: An Empirical Analysis Employing Public-Comment Procedure Data in Japan

AbstractCorporate law shapes the fundamental business environment and affects various stakeholders. It is possible to determine the behaviour of various stakeholders by examining the politics of the reform process of corporate law. In order to understand the process, this paper uses the notice-and-comment procedure (public-comment procedure). Under this procedure, people submit comments to the Ministry of Justice; some of the comments are reflected in the final Bill, while others are not. The paper performs a quantitative analysis of a hand-collected dataset from two recent public-comment procedures on corporate law reform. The results showed that the bureaucrats are rigid and not willing to take public comments seriously. However, on some technical issues, legal academics, and legal professionals influence the behaviour of the bureaucrats. In addition, the bureaucrats employed these comments to honour the technical views of professionals. In other cases, corporate managers significantly influence the reform process.

A Study on Technical High School Teachers' Views Concerning Corporal Punishment

Corporal punishment is defined as inflicting pain on body of someone who presents undesired behavior or does not present expected behavior. In the developed world, experiencing information society, corporal punishment is still in the agenda in educational system in Turkey. In this study, it was aimed to determine technical high school teachers' attitudes concerning corporal punishment in terms of various variables. The research is in scan type and a descriptive study. The research universe consists of the teachers who work at Technical High schools in Isparta, Antalya and Burdur in 2015-2016 semester. The research sample is 160 teachers who work at eighteen different schools which are at low, medium and high socio economic levels at research universe. In the research, the scale which is developed by Gozutok[4], is used to determine teachers' attitudes concerning corporal punishment. For analyzing data, for independent groups, t test and one way variance analysis are used. According to the research results; significant differences have been found out between technical school teachers' attitude towards physical punishment in terms of the socio-economic level of the schools where they work, their working years, and their gender. However, not an important difference has been found out between the attitude of teachers towards physical punishment in terms of the factors which are their marital status, having children and their class size.

Reprint of “Green decision-making model in reverse logistics using FUZZY-VIKOR method”

Due to the increasing global environmental consciousness and sustainability concerns, different industries that deal with Reverse Logistics (RL) are seeking methods to measure and analyze the impacts of their RL activities on the environment. However, making the greenest decision in the vague and complex area of RL makes this process somewhat difficult. Hence, to address these issues and provide a more meticulous and closer approach to the real world situations, a FUZZY-VIKOR method using interval-valued trapezoidal fuzzy numbers is proposed in the current research. As the further discussions explain, first, the significant factors in environmental sound practices together with the main processes and recovery options in RL are identified. Second, the influences of each green environmental factor on each RL recovery option are analyzed and ranked. To obtain concise results, the elicitation of experts is sought from among academicians and industry. The final results illustrate that, intriguingly, disposing of the returns has the lowest negative impact on the environment; thereby the best recovery option, while reselling of the returns was perceived as the worst recovery option. This research also suggests new directions for future research. From the managerial point of view, it would be interesting to study a sustainable reverse logistics through the proposed model. We only considered the impacts of environmental factors on RL, while the final decision will be more exact if the economic and societal aspects of RL are also analyzed. In addition, to reflect the technical views of all the stakeholders in RL towards the best recovery option and also take into account their concerns, we suggest designing a group decision making model across the RL using the Fuzzy-MADM methods.
