Light's twist

Arbour lights

Amongst the theoreticians there was a subspecies who interacted with experimentalists — these theorists tried to make sure that their ideas were testable and that someone tested them. Preeminent amongst these was Francis Crick who wrote all the quotes above shown in red italics (taken from Crick’s autobiographical book What Mad Pursuit: A Personal View of Scientific Discovery; Basic Books, New ...

Bezier Lights

In this paper we introduce Bezier Lights, an intelligent lighting system that allows users to intuitively establish virtual boundaries in indoor environments. Boundaries can be easily created/modified by arranging the layouts of disk-shaped devices (“stones”) on the building floor. The immediate purpose of the system is to assist users in incorporating location-aware capabilities into private p...

Lights out.

TWIST 1 ( twist homolog 1 ( Drosophila ) )

The 20.9 kDa protein encoded by TWIST1 gene is a highly conserved transcription factor that belongs to the family of basic helix-loop-helix (bHLH) proteins. In vertebrates, it is involved in embryonic development through the regulation of epithelial-mesenchymal transitions (EMT) during neural crest migration, also it regulates mesoderm determination, myogenesis, and morphogenesis (Hebrok et al....

5.1 Unbalancing Lights

Consider a square n× n array of lights (see Figure 5.1). There is one switch corresponding to each row and each column (i.e., 2n switches). Throwing a switch changes the state of all the lights in the corresponding row or column. We now consider the problem of setting the switches so as to maximize the number of lights that are on, starting from an arbitrary initial on/off configuration of the ...
