4th International Conference on Packing Problems

该奖项将支持将于2019年6月3日至7日在耶鲁大学举行的第四届包装问题国际会议。第四届包装问题国际会议将邀请来自美国、欧洲、印度、中国、日本和澳大利亚的37位受邀演讲者（40分钟的演讲），以及至少10位来自青年科学家的20分钟演讲。会议的主题将包括颗粒介质中的堆积和流动，金属合金、胶体、凝胶、液滴、泡沫和乳液中的堵塞和玻璃化转变，组织形态发生，肿瘤中的细胞堆积和蛋白质中的致密堆积。与前三届会议相比，第四届国际包装问题会议将重点关注生物材料中的干扰和玻璃化转变。包装问题会议将为初级研究人员提供至少10个20分钟的发言时间和两个90分钟的海报会议，这将允许初级研究人员介绍他们的工作并获得国际研究界对他们工作的反馈。会议将通过美国物理学会的几个单位（DBIO、DCMP、GSOFT和GSNP）的通讯向受邀演讲者所在大学的本科生、博士生和博士后做广告。为鼓励南京医科大学本科生和博士生参加，项目将为南京医科大学学生提供5笔旅行资助。颗粒形状、可变形性和摩擦力对近卡阻体系结构和力学性能的影响有待进一步研究。此外，最近的工作已经确定了发生在发育组织、癌症肿瘤、细菌细胞质和蛋白质核心中的干扰转换。第四届填充问题国际会议将汇集干扰和玻璃跃迁以及填充问题方面的专家，并允许他们与软物质和生物物理学领域的领先实验家进行互动，以确定是否可以使用晶化和玻璃跃迁的概念来解释他们研究领域中的重要开放性问题。该奖项反映了美国国家科学基金会的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。

This award will support the 4th International Conference on Packing Problems that will be held at Yale University June 3-7, 2019. The 4th International Conference on Packing Problems will feature 37 invited speakers (with 40-minute talks) from the U.S., Europe, India, China, Japan, and Australia, and at least 10 contributed 20-minute talks from junior scientists. The topics of the Conference will include packing and flows in granular media, jamming and glass transitions in metal alloys, colloids, gels, droplets, foams, and emulsions, tissue morphogenesis, cell packing in tumors, and dense packing in proteins. In contrast to the previous three Conferences, the 4th International Conference on Packing Problems will have a significant focus on jamming and glass transitions in biological materials. The Conference on Packing Problems will offer at least 10 contributed speaking slots for junior researchers to give 20-minute talks and two 90-minute poster sessions, which will allow the junior researchers to introduce their work and receive feedback on their work from the international research community. The Conference will advertise to undergraduates, Ph.D. students, and postdocs at the universities of the invited speakers and through newsletters of several Units (DBIO, DCMP, GSOFT, and GSNP) of the American Physical Society. To encourage attendance by URM undergraduates and Ph.D. students, the PI will offer 5 travel grants for URM students.How the structural and mechanical properties of systems near jamming are affected by particle shape, deformability, and friction needs further research. In addition, more recent work has identified jamming like transitions that occur in developing tissues, cancer tumors, the bacterial cytoplasm, and protein cores. The 4th International Conference on Packing Problems will bring together experts in jamming and glass transitions and packing problems and allow them to interact with the leading experimentalists in soft matter and biological physics to determine whether concepts from ja mming and glass transitions can be used to explain important open questions in their research areas.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
