A cDNA encoding the novel drug resistance gene, LRP (originally termed lung resistance-related protein), was isolated from HT1080/DR4, a 220-fold doxorubicin-resistant human fibrosarcoma cell line which displays a multidrug resistance phenotype and overexpresses the multidrug resistance protein (MRP) but does not overexpress P-glycoprotein encoded by the MDR1 gene. Using the full-length 2.8-kb ...

We calculate the fractal dimension of the infinite cluster, minimal path and its backbone for a square network of percolation by using box counting algorithms. We find for d=2, Dmin= 1.136; Df= 1.7197 ; Dbb= 1.63. The numerical values of these exponents are in good agreement with recent theoretical predictions. .

Approximate algebraic structures play a defining role in arithmetic combinatorics and have found remarkable applications to basic questions in number theory and pseudorandomness. Here we study approximate representations of finite groups: functions ψ : G → Ud such that Pr[ψ(xy) = ψ(x) ψ(y)] is large, or more generally Ex,y ‖ψ(xy)− ψ(x) ψ(y)‖22 is small, where x, y are uniformly random elements ...

The study of space-time vernier (STV) provides information on the spatio-temporal structure of the visual system in the same way that the classical spatio-spatial vernier (SSV) provides information on its spatial structure. The transposition of a SSV task into a STV one yields the following experimental format: an object (in the present case a Gaussian Blob) drifts with a constant velocity, V, ...

| In this paper a colour segmentation scheme based on two-dimensional histogram analysis and the fuzzy c-means clustering technique is presented. The method is applied to digitised epiluminescence microscopy images of pigmented skin lesions and is used for the extraction of all homogeneously coloured regions. Methods to reduce the inuence of small structures, hairs, bubbles, light re exion, and...

Kontakt: [email protected], [email protected] Results We store the attributes of Q in that pixel and shade it afterwards using our Global Illumination framework. Our algorithm operates on local surface intervals of homogeneous curvature. We thus first create a Labeled Homogeneous Curvature Map, containing unique IDs for each homogeneously curved region per pixel. We assign each scene...

Rectangular field of view demonstrating good quality shear-wave elastogram as indicated by homogeneously distributed blue colour-coded muscle (A) and evenly spaced propagation waves (B). Quantitative analysis of gastrocnemius muscle stiffness was achieved by placing the small...
