Germany may relax animal experiment rules

Animal Rights Consideration is a Necessity in Conducting an Experiment

Time to relax the rules about administration of mifepristone.

Pre-clinical and clinical data indicate that mifepristone is a safe and effective drug for the termination of pregnancy. The author suggests that it could be given by nursing staff rather than by a doctor, and that the 2-hour post-administration observation period is unnecessary in the majority of cases.

Bending rules for animal propulsion.

Animal propulsors such as wings and fins bend during motion and these bending patterns are believed to contribute to the high efficiency of animal movements compared with those of man-made designs. However, efforts to implement flexible designs have been met with contradictory performance results. Consequently, there is no clear understanding of the role played by propulsor flexibility or, more...

Multilayer Perceptrons May Learn Simple Rules Quickly

Zero temperature Gibbs learning is considered for a connected committee machine with K hidden units. For large K, the scale of the learning curve strongly depends on the target rule. When learning a perceptron, the sample size P needed for optimal generalization scales so that N P KN, where N is the dimension of the input. This even holds for a noisy perceptron rule if a new input is classiied ...

Neural Relax

We propose a new self-organizing algorithm for a feedforward network inspired to an electrostatic problem that turns out to have intimate relations with information maximization.
