Let V ⊆ [n] be a k-element subset of [n]. The uniform distribution on the 2k strings from {0, 1}n that are set to zero outside is called an (n, k)-zero-fixing source. An ϵ-extractor for sources mapping F: → 1}m, some m, such F(X) ϵ-close in statistical distance 1}m every source X. Zero-fixing were introduced by Cohen and Shinkar [7] connection with previously studied extractors bit-fixing sourc...

Hemicellulosic biomass from olive-tree pruning (OTPB) was used as a raw material in order to produce hemicellulosic hydrolysate be fermented with the non-traditional yeast Candida guilliermondii FTI 20037 obtain ethanol and xylitol. The main objectives of this research were study most relevant kinetic parameters involved bioconversion process correlation between stirred-tank bioreactor agitated...

We report on the Penn State team’s experience in the CHEMDNER chemical entity mention and the chemical document indexing tasks. Our approach devises a probabilistic framework that incorporates an ensemble of multiple information extractors to obtain high accuracy. The probabilistic framework can be configured to optimize for either precision, recall, or F-Measure based on the task requirement. ...

The link between agitated behaviors and cognitive functioning in 408 nursing home residents was examined. Results showed that cognitively impaired residents manifested aggressive behaviors (e.g., cursing, hitting) and physically nonaggressive behaviors (e.g., pacing). The highest levels of physically nonaggressive behaviors were manifested by those residents who presented intermediate levels of...

A helicopter is not possessed of an ability to fly fast compared with fixed-wing counterparts. This is a result of considerations with the main rotor. The main rotor moves in a direction very close to its plane of rotation which naturally divides it into two halves which operate under different aerodynamic conditions. One side (called the advancing side) has the rotation and translation velocit...

Randomness extractors, widely used in classical and quantum cryptography and other fields of computer science, e.g., derandomization, are functions which generate almost uniform randomness from weak sources of randomness. In the quantum setting one must take into account the quantum side information held by an adversary which might be used to break the security of the extractor. In the case of ...
