We present a practical first-order theory of a higher-order ⇡-calculus which is both sound and complete with respect to a standard semantic equivalence.

In this way we obtain an elementary labelled transition...

Rathke cleft cyst (RCC) is an uncommon albeit benign sellar lesion with an incidence rate of between 2 to 33%. RCCs are usually asymptomatic except in the large cases whit suprasellar extension. We herein describe a unique case of RCC, which presented with severe visual loss owing to massive herniation of the optic chiasm and third ventricle down into the sphenoid sinus through a small 8 x 8 mm...

The impact of invasive alien species on native communities can act at different levels both by affecting the ecosystem’s structure (i.e., mainly in case vegetation) and through direct interactions competition for food or space). Behavioral studies under controlled conditions provide relevant information potential invaders local species. In laboratory, resources between oriental shrimp Palaemon ...
