Cell migration through 3D extracellular matrices is critical to the normal development of tissues and organs and in disease processes, yet adequate analytical tools to characterize 3D migration are lacking. Here, we quantified the migration patterns of individual fibrosarcoma cells on 2D substrates and in 3D collagen matrices and found that 3D migration does not follow a random walk. Both 2D an...

The present study investigated the influence of packing material characteristics on the electricity generation performance, treatment efficiency and degradation mechanism of petroleum pollutants over microbial fuel cells (MFCs) using petroleum refinery wastewater (PRW) as fuel. The granule graphite (GG) and granule-activated carbon (GAC) were used to MFCs as packing materials, respectively. GG-...

BACKGROUND The number of physician-rating websites (PRWs) is rising rapidly, but usage is still poor. So far, there has been little discussion about what kind of variables influence usage of PRWs. OBJECTIVE We focused on sociodemographic variables, psychographic variables, and health status of PRW users and nonusers. METHODS An online survey of 1006 randomly selected German patients was con...

Gas samples and total suspended particle during work and off work time were investigated on-site and off-site electronic waste dismantling workshop (I- and O-EWDW), then compared with plastic recycling workshop (PRW) and waste incineration plant (WIP). TSP concentrations and total PBDE were 0.36-2.21 mg/m(3) and 27-2975 ng/m(3) at different workshops, respectively. BDE-47, -99, and -209 were ma...

Cell migration through extracellular matrices is critical to many physiological processes, such as tissue development, immunological response and cancer metastasis. Previous models including persistent random walk (PRW) Lévy only explain the migratory dynamics of some cell types in a homogeneous environment. Recently, it was discovered that intracellular actin flow can robustly ensure universal...

Person search is a challenging problem with various real-world applications, that aims at joint person detection and re-identification of query from uncropped gallery images. Although, previous study focuses on rich feature information learning, it’s still hard to retrieve the due occurrence appearance deformations background distractors. In this paper, we propose novel attention-aware relation...
