Arm and leg vascular responsiveness to comparable shear stimuli during isolated dynamic exercise has not been assessed in humans. Consequently, six young cyclists performed incremental, intermittent handgrip exercise (arm) and knee-extensor exercise (leg) from 5 to 60% of maximal work rate (WR). Ultrasound Doppler measurements were taken in the brachial artery (BA), common femoral artery (CFA),...

The S-box lookup is one of the most important operations in cipher algorithm design, and also is the most effective part to prevent traditional linear and differential attacks, however, when the physical implementation of the algorithm is considered, it becomes the weakest part of cryptosystems. This paper studies an active fault based implementation attack on block ciphers with S-box. Firstly,...

A nonisotopic probe (Gen-Probe PACE; Gen-Probe, Inc., San Diego, Calif.) for detection of Chlamydia trachomatis in endocervical specimens was evaluated in 344 women attending a dysplasia clinic or an obstetrics clinic and 158 women who visited an emergency room. For each patient, the probe, a tissue cell culture, and a direct immunofluorescent-antibody test (DFA; MicroTrak; Syva Co., Palo Alto,...

There is a growing demand for network devices capable of examining the content of the Data packet in order to improve the network security and provide application specific services. Most high performance systems that perform deep packet inspection implement simple string matching algorithms to match packets against a large but finite set of strings .However there is a growing interest in using ...

Endocervical infections due to Chlamydia trachomatis remain difficult to diagnose due to the lack of an inexpensive, rapid, and accurate test. We evaluated an alternative strategy for diagnosis in which initial screening was performed with an enzyme immunoassay (Chlamydiazyme) followed by a direct fluorescent antibody (DFA) test on specimens in which the Chlamydiazyme optical density (OD) readi...

Data Flow Analysis (DFA for short) is a basic technique to collect statical information on run-time behaviors of programs: it is essential in optimizing compilers and is also used in type inference problems [1]. When performing a DFA, the program to be analysed is modeled by its Control Flow Graph (CFG) and by a set of transformation functions, one for each node in the graph. The set of program...

Recent years of research have shown that the complex temporal structure of ongoing oscillations is scale-free and characterized by long-range temporal correlations. Detrended fluctuation analysis (DFA) has proven particularly useful, revealing that genetic variation, normal development, or disease can lead to differences in the scale-free amplitude modulation of oscillations. Furthermore, ampli...

A language is k-piecewise testable if it is a finite boolean combination of languages of the form Σa1Σ · · ·ΣanΣ, where ai ∈ Σ and 0 ≤ n ≤ k. We investigate the problem, given a minimal DFA recognizing a piecewise testable language, what is the minimal k for which the language is k-piecewise testable? It was shown by Klı́ma and Polák that such a k is bounded by the depth of the minimal DFA. We f...

Many global constraints can be described by a regular expression or a DFA. Originally, the regular constraint, uses a DFA to describe the constraint, however, it can also be used to express a table constraint. Thus, there are many representations for an equivalent constraint. In this paper, we investigate the effect of different representations on natural extensions of the regular constraint fo...

The correlations within the time series of the seismic electric signal (SES) activities have been studied in a previous paper [P. Varotsos, N. Sarlis, and E. Skordas, Phys. Rev. E 66, 011902 (2002)]. Here, we analyze the time series of successive high- and low-level states' durations. The existence of correlation between the states is investigated by means of Hurst and detrended fluctuation ana...
