Vasopressin and Osmoregulation: Older than you Thought

Is Belief Revision Harder Than You Thought?

Suppose one wishes to construct, use, and maintain a knowledge base (KB) of beliefs about the real world, even though the facts about that world are only partially known. In the AI domain, this problem arises when an agent has a base set of beliefs that reflect partial knowledge about the world, and then tries to incorporate new, possibly contradictory knowledge into this set of beliefs. We cho...

Pancreatic Cancer – More Familial than You Thought

Although pancreatic cancer accounts for only 2% of new cancer cases, it is the fifth leading cause of cancerrelated death in Western countries. The high mortality rate is mainly caused by the fact that most cases are detected at a stage when curable resection is not an option anymore and prognosis is poor [45,55]. The etiology of pancreatic cancer is poorly understood. Several putative risk fac...

Data Integration Is Harder than You Thought

Phosphoinositides: Older Than We First Thought?

Despite nearly 50 years of study, it is good to see that phosphoinositides are still capable of springing the odd surprise. Signaling by the second messenger phosphatidylinositol 3,4,5-trisphosphate (PtdIns(3,4,5)P(3)) was thought to be absent in yeast, but a recent paper now describes the presence of PtdIns(3,4,5)P(3) in Schizosaccharomyces pombe.

Manipulating Interpolated Data is Easier than You Thought

Data defined by interpolation is frequently found in new applications involving, for instance, geographical concepts, moving objects, and spatio-temporal data. This data leads to potentially infinite collections of items, (e.g. the elevation of any point in a map), whose definition is based on the association of a collection of samples with an interpolation function. We first argue that the man...
