Abstract:
... We experimentally design an integrated system composed of a conveyor belt and a posts array, which can simultaneously implement the function of size separation and transportation of disk particles. Differently sized particles through the post array exhibit two types of distinct migration modes that are responsible for the size separation. Furthermore, the dividing line between the two migration mo ...

Abstract:
... The discrete fracture model (DFM) has been widely used to simulate fluid flow in fractured porous media. Traditional DFM is considered to be limited on conforming meshes, hence significant difficulty may arise in generating high-quality unstructured meshes due to the complexity of the fracture networks. Recently, Xu and Yang reinterpreted DFM and demonstrated that it can actually be extended to no ...

Abstract:
... Motility allows many microbes to traverse their environment to find nutrient sources or escape unfavorable environments. However, some microbes are nonmotile and are restricted to their immediate conditions. Intriguingly, sporadic reports have demonstrated that many nonmotile microbes can utilize the motility machinery of other microbes in their vicinity. This form of transportation, called hitchh ...

Abstract:
... Food acquisition patterns and perceptions remain insufficiently understood when examining the ways urban built environments impact food access. Using surveys (N = 751) and interviews (N = 14) we argue there is a fundamental mismatch between the dominant food access narrative, which assumes proximity is the most salient factor in acquisition, and lived-experiences. Results reveal individuals’ perce ...
