When complex systems are constructed from simpler components it is important to know how properties of the components behave under composition. In this article, we present various compositionality results for security properties. In particular, we introduce a novel security property and show that this property is, in general, composable although it is weaker than forward correctability. Moreove...

We propose a simple algorithm to select group generators suitable for pairing-based cryptosystems. The selected parameters are shown to favor implementations of the Tate pairing that are at once conceptually simple and efficient, with an observed performance about 2 to 10 times better than previously reported implementations, depending on the embedding degree. Our algorithm has beneficial side ...

Introduction: The authors have carried out a retrospective analysis of data from 26 patients with developing vitiligo who were treated with oral mini-pulse of dexamethasone. Clinical response and side effects were evaluated at monthly intervals. Of the 26 patients included in the study, 12 (46.2%) presented a repigmentation of lesions, 11 (42.3%) stabilized, and 3 (11.5%) experienced a worsenin...

This paper describes our study on identifying semantic relations that exist between diseases and treatments in biomedical sentences. We focus on three semantic relations: Cure, Prevent, and Side Effect. The contributions of this paper consists in the fact that better results are obtained compared to previous studies and the fact that our research settings allow the integration of biomedical and...

Prominent ethical and policy issues such as affirmative action and female enrollment in science and engineering revolve around the idea that diversity is good. However, a precise definition is seldom provided. I show that diversity may be construed as a factual description, a craving for symmetry, an intrinsic good, an instrumental good, a symptom, or a side effect. These acceptions differ vast...

Mobile applications (apps) have permeated every walk of our life. This has motivated many companies to jump onto the «mobile wave» and develop specific apps for their products and services. With the growing number of apps, it has become ever more difficult for companies to arrest attention and to motivate users to continuously use the installed apps. A strategy that frequently is followed is to...

This paper reports about a pedagogical experiment at Zaporozhye National University (ZNU) aiming at improving motivation and learning quality in Computer Science Bachelor programme. The major novelty in teaching and learning practice introduced in the experiment was the use of peer evaluation for the assessment of coursework reports in two disciplines – one in the II-nd and the other in the IV-...
