In condensed matter physics, it is known that some topological properties of quantum systems are related to the topology of the Hamiltonian operator as a self-adjoint operator with a spectral gap. In particular, recent researches reveal that symmetries of quantum systems, such as time-reversal or particle-hole symmetries, provide a rich physical and mathematical theory. In this talk, we introdu...

The role of measurement in quantum theory remains both perplexing and controversial, especially for no-collapse interpretations (e.g., many-worlds, or the ``existential'' view). One of the outstanding challenges in these frameworks is to explain preferred bases -i.e., why measurements and observations always break unitary invariance. In this talk, I'll present a framework, motivated by informat...

Kreweras’ conjecture [1] asserts that any perfect matching of the hypercubeQd, d ≥ 2, can be extended to a Hamiltonian cycle. We proved this conjec-ture in [2] but here we present an idea of a simplified proof. The matchinggraph M(G) of a graph G is a graph whose vertex set consists of all per-fect matchings of G, with two vertices being adjacent whenever the unionof the cor...

This paper addresses the problem of automatically learning the title metadata from HTML documents. The objective is to help indexing Web resources that are poorly annotated. Other works proposed similar objectives, but they considered only titles in text format. In this paper we propose a general learning schema that allows learning textual titles based on style information and image format tit...

In the experimental sciences authors use the scientific article to express their findings by making an argumentative claim. While past studies have located the claim in the Abstract, the Introduction, and in the Discussion section, in this paper we focus on the article title as a potential source of the claim. Our investigation has suggested that titles which contain a tensed verb almost certai...

This paper deals with an application of automatic titling. The aim of such application is to attribute a title for a given text. So, our application relies on three very different automatic titling methods. The first one extracts relevant noun phrases for their use as a heading, the second one automatically constructs headings by selecting words appearing in the text, and, finally, the third on...

This paper examines the burgeoning impact of peer-to-peer (P2P) traffic IP video traffic. High-quality IPTV or Internet TV has high-bandwidth requirements, and P2P IP video could severely strain broadband networks. A model for the popularity of video titles is given, showing that some titles are very popular and will often be available locally; making localized P2P attractive for video titles. ...

Electric vehicles are playing a major role in reduction of the environmental depletion, greenhouse effect and energy saving. The electric provide cleaner quieter ambiance, reduce operating cost saves compared to fossil fuel powered because consume 75% total run vehicle. In this work scientometric analysis for savings presented by authors. is used show recent research trends applications various...

This paper investigates the indirect network effects in hardware/software system markets. It is argued in the previous literature that the sales of the hardware is highly affected by the availability of compatible software products. A majority of the previous literature has shown that software quantity is a major factor influencing hardware demand. By doing so, the effect on the hardware demand...

s of the Posters Ngoc Do, Some graph models in nano-science and solid state Abstract: Graph model is proven in many cases to be much simpler to study than other approaches and yet preserves all essential ingredients of the dispersion relation. We study some spectral problems for periodic operators originating from mathematical physics. Using quantum graph model, we analyze the dispersion relati...
