Activation of mu-opioid receptors (MORs) transfected into human embryonic kidney 293 cells, caused a multiphasic increase in cytosolic free Ca(2+) levels (Ca(2+)i). The first Ca(2+)i maximum (peak 1) between 5 and 7 s depended on the presence of extracellular Ca(2+) (Ca(2+)e). The second phase peaking at approximately 15 s (peak 2) was independent of(More)
Impossible differential cryptanalysis is a method recovering secret key by getting rid of the keys that satisfy impossible differential relations. This cryptanalysis has been used to attack AES and many good results were gotten. For the new block cipher ARIA is similar to AES in structure, it is necessary to research its security against impossible(More)
Feature extraction is a key point of pattern recognition. Wavelet features are attractive for vehicle detection because they form a compact representation, encode edges, capture information from multi-resolution, and can be computed efficiently. This paper focuses on the improvement of wavelet features. The wavelet features directly based on signed(More)
Workflow Management System is used for supporting many day-to-day workflows in large organizations. But heterogeneous and distributed computing systems make security management of WFMS decentralized, thus its security must be noticed. In this paper, we propose a role-based secure workflow model which realizes the principle of separation of duties (SoD), the(More)
The omega (ome) gene product is a modifier of larval cuticle protein 5 and its alleles (and duplicates) in the third instar of Drosophila melanogaster. Using deletion mapping the locus mapped to 70F-71A on the left arm of chromosome 3. A homozygote null mutant (ome 1) shows a pleiotropic phenotype that affected the size, developmental time of the flies, and(More)
PURPOSE In rods saturated by light, the G protein transducin undergoes translocation from the outer segment compartment, which results in the uncoupling of transducin from its innate receptor, rhodopsin. We measured the kinetics of recovery from this adaptive cellular response, while also investigating the role of phosducin, a phosphoprotein binding(More)
A monocular vision based location algorithm is presented to detect and track rear vehicles for lane change assist. The algorithm uses the shadow underneath the vehicle to extract regions of interest (ROI), and then locates vehicles with the combination of symmetry, contour and the shadow underneath a vehicle. Three symmetry criteri-ons are proposed to(More)
To examine the occurrence and outcomes of de novo metastatic (Stage IV) breast cancer, particularly with respect to tumor HER2 expression. We studied all 6,268 de novo metastatic breast cancer cases diagnosed from 1 January 2005 to 31 December 2011 and reported to the California Cancer Registry. Molecular subtypes were classified according to HER2 and(More)
