IRIS: Learning the Underlying Information of Scientific Research Interests Using Heterogeneous Network Representation
No full textUnderstanding scientific research fields and finding potential relations between seemingly distinct fields can help researchers rapidly grasp their most interested topics with expertises. In this study, we construct a heterogeneous network which contains authors, keywords, papers and institutions, and built an “Integrated Research Interest Space (IRIS)” which can represent both author and keyword nodes. Similar keywords in the sense of research interest and research manner can obvious aggregate together. Authors that are interested in different keywords distributed in different IRIS areas, with strongly associated with research objectives and methodologies of the keywords. The average similarities between authors and their real used keywords is significantly higher than that of randomly chosen author-keyword pairs. Based on these observations, we propose a simple algorithm which attempts to recommend potential interested keywords for researchers, and got meaningful results. Our study may also give useful hints for understanding research interests and discovering potential cross disciplines

Evoke: Evoking Critical Thinking Abilities in LLMs via Reviewer-Author Prompt Editing
No full textLarge language models (LLMs) have made impressive progress in natural
language processing. These models rely on proper human instructions (or
prompts) to generate suitable responses. However, the potential of LLMs are not
fully harnessed by commonly-used prompting methods: many human-in-the-loop
algorithms employ ad-hoc procedures for prompt selection; while auto prompt
generation approaches are essentially searching all possible prompts randomly
and inefficiently. We propose Evoke, an automatic prompt refinement framework.
In Evoke, there are two instances of a same LLM: one as a reviewer
(LLM-Reviewer), it scores the current prompt; the other as an author
(LLM-Author), it edits the prompt by considering the edit history and the
reviewer's feedback. Such an author-reviewer feedback loop ensures that the
prompt is refined in each iteration. We further aggregate a data selection
approach to Evoke, where only the hard samples are exposed to the LLM. The hard
samples are more important because the LLM can develop deeper understanding of
the tasks out of them, while the model may already know how to solve the easier
cases. Experimental results show that Evoke significantly outperforms existing
methods. For instance, in the challenging task of logical fallacy detection,
Evoke scores above 80, while all other baseline methods struggle to reach 20
Research on Hand Action Pattern Recognition of Bionic Limb Based on Surface Electromyography
No full textHands are important parts of a human body. It is not only the main tool for people to engage in productive labor, but also an important communication tool. When the hand moves, the human body produces a kind of signal named surface electromyography (sEMG), which is a kind of electrophysiological signal that accompanies muscle activity. It contains a lot of information about human movement consciousness. The bionic limb is driven by multi-degree-freedom control, which is got by converting the recognition result and this can meet the urgent need of people with disabilities for autonomous operation. A profound study of hand action pattern technology based on sEMG signals can achieve the ability of the bionic limb to distinguish the hand action fast and accurately. From the perspective of the pattern recognition of the bionic limb, this paper discussed the human hand action pattern recognition technology of sEMG. By analyzing and summarizing the current development of human hand movement recognition, the author proposed a bionic limb schema based on artificial neural network and the improved DT-SVM hand action recognition system. According to the research results, it is necessary to expand the type and total amount of hand movements and gesture recognition, in order to adapt to the objective requirements of the diversity of hand action patterns in the application of the bionic limb

No full textThe purpose of this dissertation is to develop a series of finite element formulationsfor rotordynamic analysis. The developed novel finite element formulationcover a relative large range of different types of elements (from one-dimensionalbeam elements, two-dimensional shell element to three-dimensional solid element).In the first place, author developed a new uniform methodology in both rotatingreference frame (RRF) and stationary reference frame (SRF) by considering theinertia effect of large displacements without any approximation for deriving theequations of motion with Lagrange formulation and the linearization process will beintroduced at last.Next, in order to exploit the nonlinear dynamic vibrational behaviour of a rotatingstructure of massive displacement, the author studied the rotating planarbeam element firstly. Then, two different approaches (the total-Lagrangian methodand the co-rotational method) are applied to take the geometrical nonlinearity intoaccount correctly for the rotating planar beam.Subsequently, author developed a new beam element with arbitrary massivedisplacement extend the planar beam element with massive displacement into thegeneral three-dimensional beam element. A series of techniques which includes thecorotational method (CR), the conformal rotational vector (CRV) and the sphericallinear interpolation (SLERP) are rst applied for finite element derivation.Then, in order to correctly predict the vibrational behaviour of a rotating structurein a complex geometric form correctly and is of a larger dimension where theinertia effect is considerably significant, the author applies the most general shelltheory (the Midlin-Ressiner theory) with large deformation, and the arbitrary staggerangle to develop a new rotating shell element to simulate the complex geometricform.At last, author developed a new solid element for rotordynamic analysis in whichthe rotational moment of inertia or the rotational motion of continuum and itsparasite spin-softening and stress-stiffening effect are included.

Les nouvelles formulations d'éléments finis développées couvrent une gamme relativement large de différents types d'éléments (éléments de poutre unidimensionnels, éléments de coque bidimensionnels et éléments solides tridimensionnels).En premier lieu, l'auteur a développé une nouvelle méthodologie à la fois dans le cadre du repère tournant (RRF) et dans celui du repère fixe (SRF) en considérant l'effet d'inertie des grands déplacements. Les équations obtenues sans aucune approximation à l'aide de la formulation de Lagrange seront linéarisées en dernier lieu.Ensuite, afin d'exploiter le comportement vibratoire dynamique non linéaire d'une structure rotative à déplacement massif, l'auteur a d'abord étudié l'élément de poutre planaire rotatif.

Ensuite, afin de prédire correctement le comportement vibratoire d'une structure rotative de forme géométrique complexe et de plus grande dimension où l'effet d'inertie est important, l'auteur applique la théorie des coques la plus générale (théorie Midlin-Ressiner) en grande déformation et avec un angle de décalage arbitraire pour avoir un nouvel élément de coque rotatif qui permet de simuler une forme géométrique complexe.

Etude sur le droit à l'information génétique
No full textEtude sur le droit à l'information génétique L'information génétique est l'élément qui vient en premier, dans la transformation technologique. L'information génétique présente les spécificités biologiques et des particularités causées par culture sur le plan subjectif et objectif et a progressivement acquis une position particulière dans le droit. Notre thèse clarifie tout d'abord la relation entre l'information génétique et la subjectivité de l'homme. L'auteur élabore les défis apportés à la théorie traditionnelle de la subjectivité par l'information génétique dans certaines relations: entre les hommes et la nature, les hommes et eux-mêmes, les hommes et les hommes, conduisant à une analyse plus approfondie à la déconstruction de la subjectivité fondée sur la dignité humaine, principe fondamental pour la sauvegarde de l'intérêt personnel. Ensuite l'auteur analyse les éléments de relation tels que les individus, les membres de la famille et les membres de la communauté qui portent les mêmes caractéristiques génétiques et les relations avec personnes extérieures telles que le médecin, la compagnie d'assurance, l'employeur et le gouvernement. Finalement il résulte des changements fondamentaux dans le droit liés à l'information génétique, intégrant le principe de dignité humaine dans ces relations. La thèse examine les attributs du droit à l'information génétique à travers les différents types de droit : le droit de la propriété intellectuelle, le consentement éclairé et le droit à l'égalité. Qui doit posséder l'information génétique qui est séparée du corps humain? Comment s'organise la circulation de l'information génétique entre sujets de droits et l'allocation des ressources dans différents domaines ? Ensuite, l'auteur explore les intérêts légitimes attendus.. Ainsi, le droit à l'information génétique échappe au modèle de droit privé traditionnel, droit de la personnalité, droit de propriété et le droit de la propriété intellectuelle et met en avant un droit de l'information génétique composé de multiples intérêts. Les principes de protection du droit de l'information génétique sont basés sur la perspective de la liberté des individus à l'égalité sociale et du principe d'équité. Sur la base des fondements théoriques du libéralisme, l'auteur souligne que la protection du droit à l'information génétique réside d'abord dans la persistance de la liberté individuelle, qui intègre des principes de liberté et d'autonomie. Ensuite, les principes de bienfaisance et de non malfaisance sont les compléments nécessaires du principe de l'autonomie. De plus, les intérêts sociaux doivent être pris en considération lors de la protection de l'information génétique, du point de vue de la justice sociale. Enfin, l'auteur souligne que la protection des droits d'information génétiques ont influencé le développement technologique, l'intérêt public social dans un environnement macro-social et l'équilibre des intérêts Enfin, l'auteur explore la pratique de la protection des droits à l'information génétique. Tout d'abord, pour prendre l'exemple de l'Union Européenne la protection des données est réglementée par la loi et les Etats membres avec signification spécifique pour l'information génétique. En inspectant les normes établies de droits à l'information génétique dans notre pays, notre protection des données est décentralisée, mais le statut juridique que doit prendre l'information génétique s'oriente plutôt vers une information spéciale. En outre, visant à la réalisation de l'équivalence des intérêts entre les individus et la société à travers la connaissance progressive profonde de la particularité de l'information génétique l'auteur par le biais de la déduction et de l'induction propose des suggestions de contre-mesures conformes à la tendance législative de la protection de l'information génétique.Genetic information has brought about profound social reform as one of the most important information resources in modern society. The protection of genetic information has concerned benefits of different entities including individuals, families, economic institutions and countries in multiple dimensions, such as private life, market and national strategy. In most of the prior research in this field, genetic information was confused with gene, as the material carrier, tissue samples and other type of personal information, neglecting the particularity of genetic information, or mere questioning of ethics and principles. But it is not enough to resolve the social problems and disputes in the case. This article establishing the vision of rights standard, along the research approach of "fact-theory-system", answers the questions: why protecting genetic information and why taking it as a right (Introduction). The article discusses the object of rights to genetic information(Chapter One), the subject of rights to genetic information(Chapter Two), the attributes of rights to genetic information(Chapter Three), developing the protection principles of rights to genetic information(Chapter Four). Finally, based on the above discussion, the author summarizes and reaffirms that the rights to genetic information is pointing to a new-type right by exploring the practice of protecting genetic information rights. In particular: In the first chapter, the author explores the genetic information, as the right object, in technological transformation. First of all, the paper defines the genetic information which differs from gene with the attributes of information and it must be acquired by Nucleic acid analysis and other scientific analysis. Second, the paper focusing on the social changes brought by genetic information, the author mainly explores the deep implications from technology to thinking-genetic information has been applied into DNA recombination technology, Human Genome Project and bio-pharmaceutical industries bring about great influence to our life through criminal justice and paternity test. Along with the technological innovation and thinking changes, new interests and disputes happened together. At last, the author explains the particularities of genetic information in technological transformation from the objective and subjective aspects. That is, genetic information has the biological specialties and particularities caused by cultural prejudices from the subjective aspect, and from the objective, genetic information are gradually given the special position of law, rising to the right object. In the second chapter, this article explains the subject of genetic information right. Firstly, clarifying the relation between genetic information and the subjectivity of human, the author elaborates the challenges to the traditional theory of subjectivity brought by genetic information-genetic information has quantified the relations: men and nature, men and themselves, men and men, leading to further analysis to the deconstruction of subjectivity based on human dignity, the important guiding significance of human dignity for safeguarding personal interest. But the protection of the rights to genetic information is not merely discussed from the perspectives of self-responsibility and human autonomy whether genetic information can be processed. The more important is, to balance the information flow among different subjects, expecting to build protection specification. Second, through comparing the way of constructing between different subjects, the author analyzes the entities of internal relationship like individuals, family members and community members who carry similar genetic information and those of external relationship like the doctor, insurance company, employer and the government, ultimately unfolding the fundamental changes of the subject of genetic information rights from human dignity to relationship. In the third chapter, the article discusses the attributes of genetic information right. To begin with, through the analyzing different types of right like intellectual property right, the informed consent right and the right of equality, the author discusses the issues: who will possess the genetic information which is separated from human body? How does the circulation of genetic information between right subjects and the resource allocation in different fields go? Then, the article explores the legitimate expectation value, reliance interests and property interests of genetic information in different dimensions and contexts. At last, reflecting from the way to boundary of right attributes in traditional private law, it escapes from the model choice that taking the rights to genetic information as personality right, property right and intellectual property right and puts forward the right attribute of genetic information, a compound maintenance for multiple interests. In the forth chapter, it explains the protection principles to genetic information right. This chapter is based on the perspective of from individual freedom to social equality and interest equivalence. The analysis goes along as follow: firstly, based on the theoretical foundation of liberalism, the author emphasizes that protecting the right to genetic information lies first in the persistence of individual freedom, explaining the individual free principles embodying as autonomy. Secondly, based on the medical theory including teleology, deontology and religious and feminism care, the author believes that a calculated decision can not be drawn only by the principle of autonomy because of the particularity of genetic information and explains that the principle of good deeds and no harm is the useful supplement to the principle of autonomy; besides, the article also emphasizes that the social interests should be taken into consideration when protecting genetic information, from the perspective of social justice, it should be stick to. And the social factors should be taken as the rationality of reallocation and the value of options of information resources. Finally, the author emphasizes the protection of genetic information rights have influenced by sense( promoting people to choose to be known or unknown of genetic information consciously or unconsciously), kinship(the similarity of genetic information brought influence to the private session of genetic information), technology development( the material ensure of the rights to genetic information with inner-motivation of self-developing), public social interest( the progress of public services requires information sharing) in macro social environment and also should insist on the principle of interest balance. In the last chapter, the author explores the practice of protecting the rights to genetic information. Firstly, from the level of EU data protection authorities and that EU data is regulated by law and member states, it introduces the protection practice of genetic information under the EU data protection framework with typical significance. Then, inspecting the established norms of genetic information rights in our country, the characteristics of our protection to genetic information rights are summed up: it is decentralized and responsive, but showing the legal status of taking genetic information as a special information in general. Moreover, it is achieving the trend of realizing the interests equivalence between individuals and the society through the gradual deep cognition of particularity of genetic information and protection of genetic information rights. At last, the author proposes countermeasure suggestions from the aspects of conforming to the legislative trend of genetic information protection, generalizing the legislation basis, clearing the obstruction of legislation and perfecting systems through deduction and induction
