Asymmetry between pushing and pulling for crawling cells.
Eukaryotic cells possess motility mechanisms allowing them not only to self-propel but also to exert forces on obstacles (to push) and to carry cargoes (to pull). To study the inherent asymmetry between active pushing and pulling we model a crawling acto-myosin cell extract as a one-dimensional layer of active gel subjected to external forces. We show that pushing is controlled by protrusion an...
متن کاملPushing and Pulling in Prokaryotic DNA Segregation
In prokaryotes, DNA can be segregated by three different types of cytoskeletal filaments. The best-understood type of partitioning (par) locus encodes an actin homolog called ParM, which forms dynamically unstable filaments that push plasmids apart in a process reminiscent of mitosis. However, the most common type of par locus, which is present on many plasmids and most bacterial chromosomes, e...
متن کاملSpindle Positioning: Actin Mediates Pushing and Pulling
To divide asymmetrically, the mitotic spindle is moved from the cell center to the cortex, a process that requires astral microtubules and the microtubule-based motor dynein. New work examining spindle positioning in large oocytes shows that in these cells actin and actin polymerization plays a key role.
متن کاملPulling, Pushing, and Grouping for Image Segmentation
This paper presents a novel computational visual grouping method, termed pulling, pushing and grouping, or PPG for short. Visual grouping is formulated as a functional optimisation process. Our computational function has three terms, the first pulls similar visual cues together, the second pushes different visual cues apart, and the third groups spatially adjacent visual cues without regarding ...
متن کاملSocial network analysis of multi-stakeholder platforms in agricultural research for development: Opportunities and constraints for innovation and scaling
Multi-stakeholder platforms (MSPs) are seen as a promising vehicle to achieve agricultural development impacts. By increasing collaboration, exchange of knowledge and influence mediation among farmers, researchers and other stakeholders, MSPs supposedly enhance their 'capacity to innovate' and contribute to the 'scaling of innovations'. The objective of this paper is to explore the capacity to ...
