A closer look at neuron interaction with track-etched microporous membranes

A Closer Look at Preduction

In a recent paper Jun Arima formalises the idea of preduc-tion { a non-monotonic schema providing a common basis for inductive and analogical reasoning. We examine some of the implications of this schema, as well as its connections with prototypes and conceptual spaces. A generalised version of his schema is motivated and developed to address diiculties with asymmetry and disjuncts.

A Closer Look at HMAC

Bellare, Canetti and Krawczyk [BCK96] show that cascading an ε-secure (fixed input length) PRF gives an O(εnq)-secure (variable input length) PRF when making at most q prefix-free queries of length n blocks. We observe that this translates to the same bound for NMAC (which is the cascade without the prefix-free requirement but an additional application of the PRF at the end), and give a matchin...

Nanopores with controlled profiles in track-etched membranes

The production of the track-etched membranes is well known in membrane science. Latent ion tracks are the result of the passage of swift ions through solid matter, they can be etched selectively in many materials. As a result, conical, cylindrical or other shape channels can be obtained. The increasing interest in polymer track-etched membranes with nano-channels is connected with the developme...

A Closer Look at Trumping1

According to Schaffer (2000a), “trumping preemption” is a category of redundant causation distinct from early and late preemption and from overdetermination. I show that the putative causal difference between causal processes in cases thought to be trumping preemption generates early preemption or overdetermination rather than trumping. I draw a novel lesson from cases thought to be trumping: t...
