purpose: using citation analysis of articles published by researchers of the engineering research institute (1991-2005), the current papers examines information seeking behavior of researchers. . methodology: for this reason, 3642 citations were extracted from 547 articles published by the researchers applying bradford's law of scattering to the cited periodicals, the most used periodicals...

background hepatitis b virus (hbv) infection is a serious global health problem that is associated with huge social and economic costs. early antiviral drugs, such as interferon-α2b, peginterferon-α2a, lamivudine, and adefovir, all have their limitations (such as low responses or safety concerns) in clinical application. telbivudine and entecavir are two of the latest nucleotide drugs and both ...

The visual span-the number of adjacent text letters that can be reliably recognized on one fixation-has been proposed as a sensory bottleneck that limits reading speed (Legge, Mansfield, & Chung, 2001). Like reading, searching for a face is an important daily task that involves pattern recognition. Is there a similar limitation on the number of faces that can be recognized in a single fixation?...

The right hemisphere has been shown to play a dominant role in processing of visuo-spatial information. Recently, this role has been studied in the two-stream rapid serial visual presentation task. In this task, two alphanumerical targets are embedded in left and right simultaneous streams of rapidly changing letters. The second target (T2) is identified better in the left than in the right vis...

When two target stimuli (T1 and T2) are presented sequentially within half a second of each other, identification accuracy is often poor for T2. This phenomenon, known as attentional blink (AB), can be observed generally only if the stimulus terminating the presentation of T2 acts as an interruption mask. Recent evidence suggests that even four small dots surrounding a target item can exert mas...

We report a small angle neutron scattering (SANS) and rheology study of cellulose derivative polyelectrolyte sodium carboxymethyl cellulose with a degree of substitution of 1.2. Using SANS, we establish that this polymer is molecularly dissolved in water with a locally stiff conformation with a stretching parameter[Formula: see text]. We determine the cross sectional radius of the chain ([Formu...

Air traffic controllers simultaneously develop complex and multiple tasks in the course of their activities. In this context, concern is raised over the high level of attention needed by these professionals which can ultimately be affected by stress and fatigue. Objectives The objective of this study was to assess attention level in air traffic controllers (ATCo). Methods 45 flight protecti...

In a typical attentional blink (AB) experiment, recognition of the second of two serially presented targets is impaired if it occurs around 200-500 ms after the first. However, recognition for the second item is often intact if the two targets occur consecutively (lag-1 sparing). Recent theories of the AB have placed great emphasis on the presence of lag-1 sparing and protracted sparing effects...

The contribution discusses variants of architectures of hybrid MT systems. The three main types of architectures are: coupling of systems (serial or parallel), architecture adaptations (integrating novel components into SMT or RMT architectures, either by pre/post-editing, or by system core modifications), and genuine hybrid systems, combining components of different paradigms. The interest is ...
