One of the gap class of segmentation genes, Krüppel (Kr), is required for normal thorax and abdominal development of the Drosophila embryo. Its gene product, a zinc-finger type protein, forms a bell-shape concentration gradient in a central position of the blastoderm. Genetic and molecular studies suggested that the Kr protein (KR) may act both as a(More)
Milk analysis is receiving increased attention. Milk contains conjugated octadecadienoic acids (18:2) purported to be anticarcinogenic, low levels of essential fatty acids, and trans fatty acids that increase when essential fatty acids are increased in dairy rations. Milk and rumen fatty acid methyl esters (FAME) were prepared using several acid- (HCl, BF3,(More)
The zinc-finger protein Krüppel (Kr) is an integral part of the Drosophila segmentation gene cascade and is essential in organogenesis during later embryonic development. In tissue culture, Kr regulates transcription. Monomeric Kr can act as a transcriptional activator, whereas Kr dimers formed at high concentrations cause repression. Here we show that(More)
The Drosophila gap gene Krüppel (Kr) encodes a transcriptional regulator. It acts both as an integral part of the Drosophila segmentation gene in the early blastoderm and in a variety of tissues and organs at later stages of embryogenesis. In transfected tissue culture cells, the Kr protein (Kr) was shown to both activate and repress gene expression in a(More)
Nacre, the crown jewel of natural materials, has been extensively studied owing to its remarkable physical properties for over 160 years. Yet, the precise structural features governing its extraordinary strength and its growth mechanism remain elusive. In this paper, we present a series of observations pertaining to the red abalone (Haliotis rufescens)(More)
Studying the dynamic evolution of time-varying volumetric data is essential in countless scientific endeavors. The ability to isolate and track features of interest allows domain scientists to better manage large complex datasets both in terms of visual understanding and computational efficiency. This work presents a new trajectory-based feature tracking(More)
TM and OpenSimulator as platforms. We describe its goals and activities, and our future plans. We conducted scientific collaboration meetings, professional seminars, a workshop, classroom instruction, public lectures, informal discussions and gatherings, and experiments in immersive, interactive visualization of high-dimensional scientific data. Perhaps the(More)
This paper presents a framework to enable parallel data analyses and visualizations that combine both Lagrangian particle data and Eulerian field data of large-scale combustion simulations. Our framework is characterized by a new range query based design that facilitates mutual queries between particles and volumetric segments. Scientists can extract(More)
