Attention capacities underlie everyday functioning from an early age onwards. Little is known about attentional processes at toddler age. A feasible assessment of attention capacities at toddler age is needed to allow further study of attention development. In this study, a test battery is piloted that consists of four tasks which intend to measure the attention systems orienting, alerting, and...

We propose a novel framework named Hidden Colored PetriNet for Alert Correlation and Understanding (HCPN-ACU) in intrusion detection system. This model is based upon the premise that intrusion detection may be viewed as an inference problem – in other words, we seek to show that system misusers are carrying out a sequence of steps to violate system security policies in some way, with earlier st...

Intrusion detection systems (IDS) suffer from a lack of scalability. Alert correlation has been introduced to address this challenge and is generally considered to be the major part of the solution. One of the steps in the correlation process is the verification of alerts. We have identified the relationships and interactions between correlation and verification. An overview of verification tes...

Lin et al. (1) claim to have discovered a positive O anomaly in water vapor from Alert, Canada, indicative of a component of stratospheric origin. However, their data (Tables S1−S5) do not support that assertion. Their finding of ΔO = 76 ± 16 ppm (2 SE) in the Alert samples is relative to a reference fractionation line [designated Chicago local precipitation (CLP)] of much lower precision [slop...

Intr Maintaining the patency of arterial lines is essential for obtaining accurate physiological measurements, enabling blood sampling and minimising the time, expense and patient discomfort incurred by line replacement. HS is commonly used to maintain and prolong arterial line patency. In 2008, a National Patient Safety Agency alert advised organisations to minimise its use for this purpose fo...
