On smart-cards, Elliptic Curve Cryptosystems (ECC) can be vulnerable to Side Channel Attacks such as the Re ned Power Analysis (RPA). This attack takes advantage of the apparition of special points of the form (0, y). In this paper, we propose a new countermeasure based on co-Z formulæ and an extension of the curve isomorphism countermeasure. It permits to transform the base point P = (x, y) in...

We represent proteins by amino acid interaction networks. This is a graph whose vertices are the proteins amino acids and whose edges are the interactions between them. Once we have compared this type of graphs to the general model of scale-free networks, we analyze the existence of nodes which highly interact, the hubs. We describe these nodes taking into account their position in the primary ...

During the development of the neuronic and visceral cranium, an important number of factors, not only genetic, but also functional, led to the apparition of some different aspects of growing at the level of each section: the basis of the cranium, the basis of the maxillary, dental alveolus, dental arch. All these "aggravating" or "compensatory" changes are added to the level of the occlusion pl...

A paradoxical worsening of pre-existing lesion or an apparition of new lesions in patients with tuberculosis during appropriate antituberculous therapy has been reported since the early years of modern chemotherapy. Such exacerbations have been noted most commonly with lung involvement, pleural effusion, lymphadenitis, and intracranial tuberculomas. In acquired immunodeficiency syndrome (AIDS)-...

Introduction / objectives Each year 30 millions of foot ulcers occur worldwide and 56% of them will become infected. These infected foot ulcer represents the leading cause of lower-limb amputation in the world and shortens dramatically the lifetime of people. The reduction of high plantar pressure in patients with peripheral neuropathy such as diabetic people is mandatory for the prevention of ...

In Charles Dickens' A Christmas Carol, Jacob Marley, Scrooge's former partner appeared to Scrooge in a ghostly apparition. "You don't believe in me," observed the ghost. "I don't," said Scrooge. "What evidence would you have of my reality beyond that of your senses?" "I don't know," said Scrooge. "Why do you doubt your senses?" "Because," said Scrooge, "a little thing affects them. A slight dis...

Résumé. Depuis son apparition au sein du W3C, la définition de la ressource Web n’a cessé d’évoluer au delà du simple document. Lieu, service, concept d’ontologie, représentation d’un objet réel ou non, la ressource web est complexe et il nous a semblé que les outils à disposition des internautes pour sa manipulation, comme les bookmarks par exemple, n’exploitaient pas pleinement ces nouvelles ...

Histological studies on teeth with marginal periodontitis, but without cavity lesions have shown a frequent apparition of modifications in the pulp tissue structure. In this study, by using the electron microscopy method, we have shown a series of interesting aspects of the intimate modifications that appear on the level of all components of the pulp tissue. The observations show that the degre...

This paper focuses on the characteristics of two big triggers that facilitated wide user adoption of the Internet: Web 2.0[1] and online social networks. We detect brakes for reproduction of these events in Internet of things. To support our hypothesis we first compare the difference between the ways of use of the Internet with the future scenarios of Internet of things. We detect barriers that...

We study the electronic and transport properties of heterostructures formed by armchair graphene nanoribbons with intersections of finite length. We describe the system by a tight-binding model and calculate the density of states and the conductance within the Green’s function formalism based on real-space renormalization techniques. We show the apparition of interface states and bound states i...
