We report a model describing the various stages of dorsal closure of Drosophila. Inspired by experimental observations, we represent the amnioserosa by 81 hexagonal cells that are coupled mechanically through the position of the nodes and the elastic forces on the edges. In addition, each cell has radial spokes representing actin filaments on which myosin(More)
Cell shape changes drive tissue morphogenesis during animal development. An important example is the apical cell constriction that initiates tissue internalisation. Apical constriction can occur through a phase of cyclic assembly and disassembly of apicomedial actomyosin networks, followed by stabilisation of these networks. Delayed negative-feedback(More)
This paper describes the creation of an environment for col-laborative engineering in which the goal is to improve the user interface by using haptic manipulation with synthetic environments. We have integrated a multiuser synthetic environment with physical robotic devices to create a work environment. These devices can move under computer control or may(More)
This paper describes several methods for using the Virtual Reality Modeling Language (VRML) as the visualization integration technology for manufacturing simulation systems. One of our goals was to develop an integration methodology based on the use of VRML translators to produce reusable VRML components. The use of readily available off-the-shelf VRML(More)
1. ABSTRACT This paper describes a set of techniques for improving access to Virtual Reality Modeling Language (VRML) environments for people with disabilities. These range from simple tex-tual additions to the VRML file to scripts which aid in the creation of more accessible worlds. We also propose an initial set of guidelines authors can use to improve(More)
Protein phosphatases type 2C (PP2Cs) from group A, which includes the ABI1/HAB1 and PP2CA branches, are key negative regulators of ABA signaling. HAI-1 gene had been shown to affect both seed and vegetative responses to ABA, which is one of PP2Cs clade A in Arabidopsis thaliana. Transgenic plants containing pHAI-1::GUS (β-glucuronidase) displayed GUS(More)
The National Institute of Standards and Technology (NIST) is developing a digital library of mathematical functions to replace the widely used National Bureau of Standards Handbook of Mathematical Functions [Abramowitz and Stegun 1964]. The NIST Digital Library of Mathematical Functions (DLMF) will provide a wide range of information about high level(More)
This papa describes the use. of the Vial RealityModelingLan-guage (V'RML)in the VIM-Vial Interface to Manufacturing system.The VIM prototype demonstrates the technical feasibility of using a variety of intiace techniqu= for data acce.sa.VIM is Web based and contains data for the manufacture of a miter saw.

The widespread use of high level mathematical functions to solve problems in the mathematical and physical sciences has led the National Institute of Standards and Technology to engage in a massive project to update and expand the National Bureau of Standards Handbook of Mathematical Functions [1]. The handbook, which discusses the definition and(More)
