Aggregation Operators and the Lipschitzian Condition [PDF]
2007 IEEE International Fuzzy Systems Conference, 2007 Lipschitzian and kernel aggregation operators with respect to the natural T-indistinguishability operator ET and their powers are studied. A t-norm T is proved to be ETLipschitzian, and is interpreted as a fuzzy point and a fuzzy map as well. Given an Archimedean t-norm T with additive generator t, the quasi-arithmetic mean generated by t is proved to ...

`Operational' energy conditions [PDF]
Classical and Quantum Gravity, 1998 I show that a quantized Klein-Gordon field in Minkowski space obeys an `operational' weak energy condition: the energy of an isolated device constructed to measure or trap the energy in a region, plus the energy it measures or traps, cannot be negative.

Operant conditioning in invertebrates [PDF]
Current Opinion in Neurobiology, 2003 Learning to anticipate future events on the basis of past experience with the consequences of one’s own behavior (operant conditioning) is a simple form of learning that humans share with most other animals, including invertebrates. Three model organisms have recently made significant contributions towards a mechanistic model of operant conditioning ...
