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:
... 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 ...

Abstract:
... The study of pro-environmental behavior has been dominated by self-report scales and field observations. Although both approaches have their merits, they also suffer from critical limitations that obstruct progress towards a better understanding of pro-environmental behavior. The Pro-Environmental Behavior Task (PEBT) was developed to address these limitations by facilitating the study of actual p ...
