9604250 Suki This U.S.-Brazil award will support collaborative research between Dr. Bela Suki of Boston University and Professor Jose Andrade at Federal do Ceara, on the project entitled, "Threshold Phenomena and Avalanches in Physiological Tree Structures." A curious phenomenon has been noted during procedures such as heart surgery, where the clamping off of blood vessels stops the blood flow to parts of the body other than the part being operated on. It was thought that the flow would be diverted, taking another course. This project will address this problem. Specifically, the PIs believe that vessels and airways are parts of a tree structure and the the opening and closing is influenced by the closing or opening of other segments of the tree. They describe this as a highly discontinuous avalanche phenomenon. The goal of their project is to further the analytic procedures necessary to solve this problem. ***

小行星9604250 这个美国-巴西奖将支持波士顿大学的Bela Suki博士和联邦塞阿拉的Jose Andrade教授在题为“生理树结构中的阈值现象和雪崩”的项目上进行合作研究。" 在心脏手术等过程中，人们注意到了一个奇怪的现象，即血管的夹紧会阻止血液流向身体的其他部位，而不是手术部位。人们认为，血液流动会被转移，进入另一个过程。 这个项目将解决这个问题。 具体来说，PI认为血管和气道是树结构的一部分，其打开和关闭受到树其他部分的关闭或打开的影响。 他们将其描述为一种高度不连续的雪崩现象。 他们的项目的目标是进一步解决这个问题所需的分析程序。 ***
