A significant component of human observational learning is the ability to focus attention toward important or relevant input features. Amechanism with this capability can serve as an inductive bias to facilitate learning in both humans and machines. Past attempts to model attentional focus for human learning have postulated a single salience value for each feature, such that features with great...

Commencing in the late 1880s Pierre Janet developed the most complete theory of dissociation of his time. It has been suggested that Janet later repudiated his belief in dissociation theory (e.g., Hacking, 1995). Recently this viewpoint has been cited to support skepticism in dissociative identity disorder and researchers and clinicians of dissociation may be faced with such suggestions to chal...

Optimization heuristics are often compared with each other to determine which one performs best by means of worst-case performance ratio reflecting the quality of returned solution in the worst case. The domination number is a complement parameter indicating the quality of the heuristic in hand by determining how many feasible solutions are dominated by the heuristic solution. We prove that the...

As the wheels of a biplane approach a desolate airfield in the Solomon Islands, a man wearing only a loincloth breaks through the brush, brandishing a spear and a flail. From behind the plane’s windows four biologists watch with wary eyes and silently map an escape route. “You’re thinking, ‘What am I supposed to do here?’” recalls Janet Hemingway, Director of the Liverpool School of Tropical Me...

Aneurysms of the persistent trigeminal artery (PTA) trunk are exceptionally rare and have a high risk for rupture. Dual stent placement through each internal carotid and basilar artery for endovascular coil embolization of a fusiform aneurysm arising from the PTA has not been described in the literature. A 44-year-old female with a history of chronic headache was identified to have a fusiform a...

Background: nitrogen oxides occur in the atmosphere in Six forms of namely: N2O , NO , NO2 , N2O3, N2O4 and N2O5 .Among these oxides NO2 is the most important air pollutant because of its relatively high toxicity and its ubiquity in ambient air. In this research Griess-Saltzman method was utilized for determination of nitric oxide and nitrogen dioxide in the atmosphere of different laboratori...

This paper describes Janet package — highly expressive Java language extension that enables convenient creation of powerful native methods and efficient Java-to-native code interfaces. Java native interface (JNI) is a low-level API that is rather inconvenient if used directly. Therefore Janet, as the higher-level tool, combines flexibility of JNI with Java’s ease-of-use. Performance results of ...
