The competence transcription factor ComK plays a central role in competence development in Bacillus subtilis by activating the transcription of the K regulon. ComK-activated genes are characterized by the presence of a specific sequence to which ComK binds, a K-box, in their upstream DNA region. Each K-box consists of two AT-boxes with the consensus sequence AAAA-(N)(5)-TTTT, which are separate...

We investigate the problem of finding orthogonal polygons that fold to plural incongruent orthogonal boxes. There are two known polygons that fold to produce two incongruent orthogonal boxes. In this paper, we show that there are infinite such polygons. We also show that there exists a tile that produces two incongruent orthogonal boxes.

We describe an application of the BOXES learning algorithm of Michie and Chambers (1968) to a large-scale, real-world problem, namely, learning to control a steel mill. By applying BOXES to a model of a skinpass mill (a type of steel mill), we find that the BOXES algorithm can be made to produce a robust controller relatively quickly. Various aspects of the BOXES algorithm are adapted for the t...

In some historical opera halls there are boxes located around the proscenium, commonly called proscenium or "director" boxes. These boxes have a certain influence on the initial part of the impulse response of an opera hall on the singer-auditorium, singer-singer, and singer-orchestra pit paths. During the reconstruction of the Ljubljana opera hall, measurement of a scaled model was performed t...
