Genetic mosaics can be used to gain insight into the cell specificity of gene function. How Caenorhabditis elegans mosaics are typically generated is reviewed, and several examples with relevance to developmental studies are mentioned. One example is mpk-1, which encodes a member of the Ras-MAP-kinase pathway. mpk-1 mosaics have been a means of studying the distinct cells that require the gene ...

This thesis presents the design of a Graphical User Interface (GUI) for computer-based sound synthesis to support users in the externalisation of their musical ideas when interacting with the system in order to create and manipulate sound. The approach taken consisted of three research stages. The first stage was the formulation of a novel visualisation framework to display perceptual dimension...

We describe a process for creating an image mosaic—a collection of small images arranged in such a way that when they are seen together from a distance they suggest a larger image. To visually suggest the larger form, the small images are arranged to match a large picture as much as possible, and then their colors are adjusted to better suggest the overall form. Arrangement of the small images ...

Retinal cells are regularly spaced across the retina and form mosaic-like patterns. The developmental processes involved in producing such mosaics are unclear, although recent evidence suggests that lateral movement of cells may be involved [1]. In this paper, we extend a model of neurite outgrowth [2] to allow cells to move as well as to change their dendritic extent. Starting from random init...

The effects of various lethal mutations were studied when they were present in the hemizygous state as sectors in genetic mosaics (gynandromorphs) of Drosophila melanogaster. Sixty percent of the lethals studied can survive to adulthood in combination with normal tissue in mosaics, whereas the remainder cause the death of such mosaic animals. Some of the gynandromorph-viable lethals appeared to...

The U.S. Strategic Environmental Research and Development Program (SERDP) has supported a) the development of software tools for generating underwater landscape mosaics without relying on external navigation and b) the evaluation of these mosaics for coral reef mapping and monitoring. We are seeking to identify potential applications and partners. Data Acquisition Requirements: Mosaics are made...
