Membrane tethers are extracted at constant velocity from neuronal growth cones using a force generated by a laser tweezers trap. A thermodynamic analysis shows that as the tether is extended, energy is stored in the tether as bending and adhesion energies and in the cell body as "nonlocal" bending. It is postulated that energy is dissipated by three viscous(More)

Utilizing the nonuniform latencies of SDRAM devices, access reordering mechanisms alter the sequence of main memory access streams to reduce the observed access latency. Using a revised M5 simulator with an accurate SDRAM module, the burst scheduling access reordering mechanism is proposed and compared to conventional in order memory scheduling as well as(More)
Attribute based proxy re-encryption scheme (ABPRE) is a new cryptographic primitive which extends the traditional proxy re-encryption (public key or identity based cryptosystem) to the attribute based counterpart, and thus empower users with delegating capability in the access control environment. Users, identified by attributes, could freely designate a(More)
Big data, because it can mine new knowledge for economic growth and technical innovation, has recently received considerable attention, and many research efforts have been directed to big data processing due to its high volume, velocity, and variety (referred to as "3V") challenges. However, in addition to the 3V challenges, the flourishing of big data also(More)
To construct a suitable and secure proxy re-signature scheme is not an easy job, up to now, there exist only three schemes, one is proposed by Blaze et al. [6] at EUROCRYPT 1998, and the others are proposed by Ateniese and Hohenberger [2] at ACM CCS 2005. However, none of these schemes is proved in the standard model (i.e., do not rely on the random oracle(More)
The degradation kinetics of a near-infrared fluorescent, diagnostic, and photodynamic agent, indocyanine green (ICG), was investigated in aqueous solution by steady-state fluorescence technique. The influence of ICG concentration on its fluorescence spectrum was determined. The degradation kinetics of ICG in aqueous solution was studied as a function of(More)
OBJECTIVE To explore the effect of early goal-directed therapy (EGDT) according to pulse indicated continuous cardiac output (PiCCO) on septic shock patients. METHODS Eighty-two septic shock patients in Subei People's Hospital of Jiangsu Province from January 2009 to December 2012 were enrolled and randomly divided into two groups using a random number(More)
