Dihydropyridine receptor (DHPR), an L-type Ca(2+) channel complex, plays an essential role in muscle contraction, secretion, integration of synaptic input in neurons and synaptic transmission. The molecular architecture of DHPR complex remains elusive. Here we present a 15-Å resolution cryo-electron microscopy structure of the skeletal DHPR/L-type Ca(2+) channel complex. The DHPR has an asymmet...

This paper presents a method of contour extraction and compression from grey level image. The proposed algorithm is applied in spectral domain using single-level wavelet transform (WT). Single step parallel contour extraction (SSPCE) method is used for the binary image after inverse wavelet transform is applied to the details images. Then the contours are compressed using either Ramer or Trapez...

In this paper, the multi-person decision making problems with various different types of incomplete linguistic preference relations are studied. Some new concepts, including incomplete uncertain linguistic preference relation, incomplete triangular fuzzy linguistic preference relation, incomplete trapezoid fuzzy linguistic preference relation, expected incomplete linguistic preference relation ...

Planar sub-wavelength resonators have been used for sensing applications, but different types of advantages and disadvantages. The split ring resonator (SRR) has a smaller region is suitable microfluidic the sensitivity can be limited. Meanwhile, complementary electric-LC (CELCR) larger higher sensitivity, topology cannot easily designed to reduce region. In this work, we propose new design tha...

We investigate ordering properties of two-dimensional granular materials using several shapes created by welding ball bearings together. Ordered domains form much more easily in two than in three dimensions, even when configurations lack long-range order. The onset of ordered domains occurs near a packing density of 0.8, a phenomenon observed previously for disks. One of our shapes, the trapezo...

A fast, practical, deterministic algorithm for the horizontal trapezoidation of simple polygons is presented. The polygon is decomposed into a minimal collection of trapezoid sequences, such that two trapezoids adjacent within a sequence always share a common horizontal border. Such trapezoid sequences are a convenient data structure in a display list for a collection of polygonal objects to be...

We define a new class of ordered sets, called free triangle orders. These are ordered sets represented by a left-to-right ordering on geometric objects contained in a horizontal strip in the plane. The objects are called “free triangles,” and have one vertex on each of the two boundaries of the strip and one vertex in its interior. These ordered sets generalize the classes of trapezoid and tria...
