Lee et al. proposed two methods to speed up the computation of scalar multiplication of elliptic curve defined over GF (2) with a medium size of m in the range 10 ≤ m ≤ 20. In these methods, Frobenius map is utilized to expand the integer k and each coefficient of the expansion is represented as a binary string. In this paper, with the application of joint sparse form (JSF) to the coefficients,...

Development of information technology results in creation of more and more advanced teaching assisting systems. The authors of the article made an attempt to design and use the adaptative educational system based on the technologies: J2EE, JSF and XML. Unlike most hitherto solutions, the authors propose a three-tier architecture of the system and its improvement with additional functionalities.

In the following article we describe the architecture of an online store project, which is an application utilising Java Enterprise Edition. Our project is based on a customer expectations model. The choice of technology has been due to its easy expandability by additional modules as well as its functionality which does not require reorganising the existing code.

Behavioral studies have shown that picture-plane inversion impacts face and object recognition differently, thereby suggesting face-specific processing mechanisms in the human brain. Here we used event-related potentials to investigate the time course of this behavioral inversion effect in both faces and novel objects. ERPs were recorded for 14 subjects presented with upright and inverted visua...

A summary on the most recent results of the ATLAS and CMS Collaborations on the top quark porperties is presented. The measurements used data from the 2010 and 2011 LHC run, using integrated luminosities ranging from 35 pb −1 to 5.0 f b −1 , the latter corresponding to the full 2011 data sample. c Copyright owned by the author(s) under the terms of the Creative Commons Attribution-NonCommercial...

Recent research has shown that attention can influence the strength of face aftereffects. For example, attending to changes in facial features increases the strength of identity and figural aftereffects relative to passive viewing (Rhodes et al., 2011). Here, we ask whether attending to a specific social dimension of a face (such as race or gender) influences the strength of face aftereffects a...

Although a crucial role of the fusiform gyrus (FG) in face processing has been demonstrated with a variety of methods, converging evidence suggests that face processing involves an interactive and overlapping processing cascade in distributed brain areas. Here we examine the spatio-temporal stages and their functional tuning to face inversion, presence and configuration of inner features, and f...

Diagnostic features of emotional expressions are differentially distributed across the face. The current study examined whether these diagnostic features are preferentially attended to even when they are irrelevant for the task at hand or when faces appear at different locations in the visual field. To this aim, fearful, happy and neutral faces were presented to healthy individuals in two exper...

Gold nanoparticles grown within the intracellular confines of living cells are introduced as potential surface-enhanced Raman scattering (SERS) substrates for confocal Raman spectrometry. Electron microscopy and a silver-enhanced reflectance laser scanning confocal microscopic approach were used to visualize the size, shape, and distribution of intracellularly grown gold nanoparticles (IGAuN) a...

The design of analog and radio-frequency (RF) circuits in CMOS technology becomes increasingly more difficult as device modeling faces new challenges in deep submicrometer processes and emerging circuit applications. The sophisticated set of characteristics used to represent today’s “digital” technologies often proves inadequate for analog and RF design, mandating many additional measurements a...
