The largest source of information is the WWW. Gathering of novel information from this network constitutes a real challenge for artificial intelligence (AI) methods. Large search engines do not offer a satisfactory solution, their indexing cycle is long and creates a time lag of about one month. Moreover, sometimes search engines offer a huge amount of documents, which is hard to constrain and ...

Little is known about the relationships between adverse health effects and unhealthy behaviors among medical students using Facebook. The aim of this study was to determine the associations between adverse health effects and unhealthy behaviors with Facebook use. A cross-sectional study was conducted in a private university in Malaysia among 316 medical students. A self-administered questionnai...

Today, smartphones are widely used and they already have a growing market share of more than 70% according to recent studies. These devices often contain sensitive data like contacts, pictures, or even passwords that can easily be accessed by an attacker if the phone is not locked. Since they are mobile and used as everyday gadgets, they are susceptible to get lost or stolen. Hence, access cont...

We report the surface phonon dispersion of topological insulator Sb2Te3 together with a number additional inelastic events, including resonance enhancement, kinematical focusing and surfing.

Contextual advertising systems suggest suitable advertisings to users while surfing the Web. Focusing on text summarization, we propose novel techniques for contextual advertising. Comparative experiments between these techniques and existing ones have been performed.

The spread of viral infections involves the directional progression of virus particles from infected cells to uninfected target cells. Prior to entry, the binding of virus particles to specific cell surface receptors can trigger virus surfing, an actin-dependent lateral transport of viruses toward the cell body (M. J. Lehmann et al., J. Cell Biol. 170:317-325, 2005; M. Schelhaas, et al., PLoS P...

Information Security is the most describing problem in present times. To cop up with the security of the information, the passwords were introduced. The alphanumeric passwords are the most popular authentication method and still used up to now. However, text based passwords suffer from various drawbacks such as they are easy to crack through dictionary attacks, brute force attacks, keylogger, s...

There is an increasing recognition that evolutionary processes play a key role in determining the dynamics of range expansion. Recent work demonstrates that neutral mutations arising near the edge of a range expansion sometimes surf on the expanding front leading them rather than that leads to reach much greater spatial distribution and frequency than expected in stationary populations. Here, w...

BACKGROUND Surfing is an increasingly popular activity and surfing-related injuries have increased accordingly. However, to the best of our knowledge, there are no reports of penetrating upper airway injuries in surfers. We present a "cannot ventilate, cannot intubate" situation following penetrating neck injury by a surfboard fin. CASE PRESENTATION A previously healthy 29-year-old Japanese m...
