Sing and learn

Making gene circuits sing.

H ow many tries did it take to get that to work? The doubleedged question, which arises regularly at synthetic biology meetings, succinctly summarizes a major hurdle for the field; even with the successes and enormous potential for the construction of genetic circuits in living cells, it is commonly understood that cloning and computational expertise do not typically lead to circuits that funct...

Learning lyrics: to sing or not to sing?

According to common practice and oral tradition, learning verbal materials through song should facilitate word recall. In the present study, we provide evidence against this belief. In Experiment 1, 36 university students, half of them musicians, learned an unfamiliar song in three conditions. In the sung-sung condition, the song to be learned was sung, and the response was sung too. In the sun...

Character Recognition U sing Canonical

This paper presents a new insight into character recognition problem. Implicit polynomial (IP) curves have been used for modelling characters. A unique decomposition theorem is employed to decompose these curves into simple line primitives. For the comparison of the characters, canonical invariants have been computed using so called "related points" of the curves, which are the real intersectio...

FIFO and LIFO sing the BLUes

FIFO, First-In-First-Out. and LIFO, Last-In-FirstOut, are well-known techniques for handling sequences. In TJ$ macro writing they are abundant but are not easily recognized as such. TJ$ templates for FIFO and LIFO are given and their use illustrated. The relation with Knuth's \dolist, answer ex11.5, and \ctest. p.376, is given.
