9603035 Glazier This award supports a three year collaborative research project between Professor James Glazier of the University od Notre Dame and Professor Masaki Sano of the Tohoku University in Sendai, Japan. This project provides for research in the area of pattern formation and complex systems. The researchers will be studying cell sorting and turbulence. They will study the physical and biological mechanisms of cell sorting during embryonic development, both theoretically and experimentally. This should establish detailed quantitative agreement between experiments and the Potts model simulations and explain several morphogenic processes. Their next goal is to study turbulence in Rayleigh-Benard convection in Hg. They will accomplish this by characterizing the velocity histograms and spectra of hard turbulence using new velocity probes. They will then determine velocity histograms for the ultrahard turbulence regime which they expect to differ from hard turbulence. The proposal brings together the efforts of two laboratories which both work on living and non-living materials and both combine experimental and theoretical studies of physical and biological pattern formation. Their equipment and expertise is also complementary. The results of the research will provide realistic parameters in their computer models that would allow for full quantitative simulations. Through the exchange of ideas and technology, this project will broaden our base of basic knowledge and promote international ulderstanding and cooperation.

9603035 Glazier该奖项支持圣母大学的James Glazier教授和日本仙台东北大学的Masaki Sano教授之间为期三年的合作研究项目。这个项目提供了在图案形成和复杂系统领域的研究。研究人员将研究细胞分类和湍流。他们将从理论和实验两方面研究胚胎发育过程中细胞分选的物理和生物学机制。这应该会在实验和Potts模型模拟之间建立详细的定量一致，并解释几个形态形成过程。他们的下一个目标是研究汞中瑞利-贝纳德对流中的湍流。他们将通过使用新的速度探测器来表征硬湍流的速度直方图和频谱来实现这一点。然后，他们将确定超硬湍流区的速度直方图，他们预计这与硬湍流区不同。该提案汇集了两个实验室的努力，这两个实验室都致力于研究生物和生物材料，并将物理和生物模式形成的实验和理论研究结合在一起。他们的设备和专业知识也是相辅相成的。研究结果将在他们的计算机模型中提供现实的参数，从而允许进行全面的定量模拟。通过思想和技术的交流，这个项目将扩大我们的基础知识基础，促进国际了解和合作。
