Cancer cells alter their migratory properties during tumor progression to invade surrounding tissues and metastasize to distant sites. However, it remains unclear how migratory behaviors differ between tumor cells of different malignancy and whether these migratory behaviors can be utilized to assess the malignant potential of tumor cells. Here, we analyzed(More)
Networks in nature are often formed within a spatial domain in a dynamical manner, gaining links and nodes as they develop over time. Motivated by the growth and development of neuronal networks, we propose a class of spatially-based growing network models and investigate the resulting statistical network properties as a function of the dimension and(More)
We present analytical and numerical studies of a photonic lattice with short-and long-range harmonic modulations of the refractive index. Such structures can be prepared experimentally with holographic photolithog-raphy. In the spectral region of the photonic bandgap of the underlying single-periodic crystal, we observe a series of bands with anomalously(More)
Since the cytoskeleton is known to regulate many cell functions, an increasing amount of effort to characterize cells by their mechanical properties has occured. Despite the structural complexity and dynamics of the multicomponent cytoskeleton, mechanical measurements on single cells are often fit to simple models with two to three parameters, and those(More)
The physics of lipid bilayers has been studied for varying lipid and protein constituents. The effects of molecules that transiently associate with the bilayer is a new area of research. In this work, we focus on two proteins involved in vesicle trafficking inside cells, Arf1 and ArfGAP1. Research has suggested that these proteins may act as curvature(More)
