Certain quantum phases, such as topological order, are notoriously difficult for computers to identify. The challenge grows with the correlation length, a measure of how far the p ...

1. Fast and Slow Piles. This works well as a starting or closing activity. Students sort math fact cards into fast and slow piles. This visual way of tracking facts highlights which facts come ...

The generation of femtosecond optical pulses 1 has opened up a range of applications from real-time monitoring of chemical reactions through to ultrahigh-bit-rate optical communications 2, and has led ...

Two experiments were carried out to compare two techniques (amino acid supplementation and dilution) for formulating experimental diets for pre-starter (1 to 8 days) and starter (8 to 22 days) broiler ...

The chirality index J is a multiplying factor, indicating that the cross-over is universal for singular band-gap systems of different chiralities. The cross-over can also be seen from the divergence ...
