When cargos jump tracks
Cancer cells straighten out W hen a cancer cell hangs a left, it needs the protein cofi lin. As Sidani et al. report, cofi lin helps wandering cancer cells change course by enabling them to turn. Cofi lin is important for cells on the go. As a cell crawls, actin fi bers at its front edge polymerize, pushing the membrane forward. Cofi lin promotes the elongation of these fi bers by breaking them...
متن کاملOptimal Portfolios when Volatility can Jump
We consider an asset allocation problem in a continuous-time model with stochastic volatility and (possibly correlated) jumps in both, the asset price and its volatility. First, we derive the optimal portfolio for an investor with constant relative risk aversion. One main finding is that the demand for jump risk now also includes a hedging component, which is not present in models without jumps...
متن کاملQueues Don't Matter When You Can JUMP Them!
QJUMP is a simple and immediately deployable approach to controlling network interference in datacenter networks. Network interference occurs when congestion from throughput-intensive applications causes queueing that delays traffic from latency-sensitive applications. To mitigate network interference, QJUMP applies Internet QoS-inspired techniques to datacenter applications. Each application i...
متن کاملClathrin-independent endocytosis of ubiquitinated cargos.
Plasma membrane receptors can be endocytosed through clathrin-dependent and clathrin-independent pathways. Here, we show that the epidermal growth factor (EGF) receptor (EGFR), when stimulated with low doses of EGF, is internalized almost exclusively through the clathrin pathway, and it is not ubiquitinated. At higher concentrations of ligand, however, a substantial fraction of the receptor is ...
متن کاملTripartite Line Tracks - Bipartite Line Tracks
Theories of shapes are important for object recognition and for reasoning about the behaviour of objects, both tasks strongly constrained by shape. Whereas the extraction of shape properties has extensively been studied in vision, there is still a lack of qualitative shape descriptions which allow reasoning about shapes with AI techniques in a flexible manner. In this paper we present a qualita...
