The structure of the prokaryotic cyclic nucleotide-modulated potassium channel MIoK1 at 16 angstrom resolution

The gating ring of cyclic nucleotide-modulated channels is proposed to be either a two-fold symmetric dimer of dinners or a four-fold symmetric tetramer based on high-resolution structure data of soluble cyclic nucleotide-binding domains and functional dat ...

Continuous Wavelet Transform on the Hyperboloid

Pierre Vandergheynst, Iva Bogdanova Vandergheynst

In this paper we build a Continuous Wavelet Transform (CWT) on the upper sheet of the 2-hyperboloid

H_+^2

. First, we define a class of suitable dilations on the hyperboloid through conic projection. Then, incorporating hyperbolic motions belonging to $SO ...

An Optimized Spline-Based Registration of a 3D CT to a Set of C-Arm Images

Michaël Unser, Philippe Thévenaz

We have developed an algorithm for the rigid-body registration of a CT volume to a set of C-arm images. The algorithm uses a gradient-based iterative minimization of a least-squares measure of dissimilarity between the C-arm images and projections of the C ...

Distance preserving flattening of surface sections

Roger Hersch, Laurent Saroul

Curved cross-sections extracted from medical volume images are useful for analyzing nonplanar anatomic structures such as the aorta arch or the pelvis. For visualization and for performing distance measurements, extracted surface sections need to be adequa ...

Adapting and applying SPECT to the investigation of reaction rate distributions within lightly activated nuclear fuel pins

Rakesh Chawla, Fabian Jatuff

Single Photon Emission Computerised Tomography, a non-destructive imaging technique particularly employed for medical diagnoses, has been adapted and applied for the first time to the study of two-dimensional reaction rate distributions within lightly acti ...

Wavelets on the 2-Hyperboloid

Pierre Vandergheynst, Iva Bogdanova Vandergheynst

We build wavelets on the 2-Hyperboloid. First, we define dilations on the hyperboloid through conic projection. Then, incorporating hyperbolic motions belonging to

SO_0(1,2)

, we define a family of hyperbolic wavelets. The continuous wavelet transform (CW ...

Multiresolution-Based Registration of a Volume to a Set of Its Projections

Michaël Unser, Philippe Thévenaz

We have developed an algorithm for the rigid-body registration of a 3D CT to a set of C-arm images by matching them to computed cone-beam projections of the CT (DRRs). We precomputed rescaled versions (pyramid) of the CT volume and of the C-arm images. We ...

The 6.9-angstrom structure of GlpF: A basis for homology modeling of the glycerol channel from Escherichia coli

Henning Paul-Julius Stahlberg, Andreas Engel

The three-dimensional structure of GlpF, the glycerol facilitator of Escherichia coli, was determined by cryo-electron microscopy, The 6.9-Angstrom density map calculated from images of two-dimensional crystals shows the GlpF helices to be similar to those ...

The aquaporin sidedness revisited

Henning Paul-Julius Stahlberg, Andreas Engel

Aquaporins are transmembrane water channel proteins, which play important functions in the osmoregulation and water balance of microorganisms, plants, and animal tissues. All aquaporins studied to date are thought to be tetrameric assemblies of four subuni ...

Fractional Derivatives, Splines and Tomography

Michaël Unser, Thierry Blu

We develop a spline calculus for dealing with fractional derivatives. After a brief review of fractional splines, we present the main formulas for computing the fractional derivatives of the underlying basis functions. In particular, we show that the $ γ ...
