ECM signals ECM degradation
W hen Caroline Damsky moved her lab to the University of California, San Francisco, in 1985, she knew she would have an instant colleague in Zena Werb. There was a natural connection between their work. That connection would be refl ected in their discoveries, which delineated an integrin-mediated pathway from the extracellular matrix (ECM) outside the cell to the internal, gene-expressing life...
متن کاملThe Phosphoinositide-Binding Protein ZF21 Regulates ECM Degradation by Invadopodia
During the process of tumor invasion, cells require footholds on extracellular matrices (ECM) that are created by forming focal adhesions (FAs) using integrins. On the other hand, cells must degrade the ECM barrier using extracellular proteases including MMPs in the direction of cell movement. Degradation occurs at the leading edges or invadopodia of cells, which are enriched in proteases and a...
متن کاملSubarray-based FDA radar to counteract deceptive ECM signals
In recent years, the frequency diverse array (FDA) radar concept has attracted extensive attention, as it may benefit from a small frequency increment, compared to the carrier frequency across the array elements and thereby achieve an array factor that is a function of the angle, the time, and the range which is superior to the conventional phase array radar (PAR). However, limited effort on th...
متن کاملJKL-ECM: an implementation of ECM using Hessian curves
We present JKL-ECM, an implementation of the elliptic curve method of integer factorization which uses certain twisted Hessian curves in a family studied by Jeon, Kim and Lee. This implementation takes advantage of torsion subgroup injection for families of elliptic curves over a quartic number field, in addition to the ‘small parameter’ speedup. We produced thousands of curves with torsion Z/6...
متن کاملECM on Graphics Cards
This paper reports record-setting performance for the ellipticcurve method of integer factorization: for example, 604.99 curves/second for ECM stage 1 with B1 = 8192 for 280-bit integers on a single PC. The state-of-the-art GMP-ECM software handles 171.42 curves/second for ECM stage 1 with B1 = 8192 for 280-bit integers using all four cores of a 2.4GHz Core 2 Quad Q6600. The extra speed takes a...
