On a certain nonstationary problem in a dihedral angle. II
Journal of Mathematical Sciences, 1994An existence theorem is obtained for the initial-boundary value problem, considered in the previous paper, in the case of a positive parameter h in the boundary condition.

Protein secondary structure prediction with dihedral angles
Proteins: Structure, Function, and Bioinformatics, 2005AbstractWe present DESTRUCT, a new method of protein secondary structure prediction, which achieves a three‐state accuracy (Q3) of 79.4% in a cross‐validated trial on a nonredundant set of 513 proteins. An iterative set of cascade–correlation neural networks is used to predict both secondary structure and ψ dihedral angles, with predicted values ...

Backbone Dihedral Angle Prediction
2016More than two decades of research have enabled dihedral angle predictions at an accuracy that makes them an interesting alternative or supplement to secondary structure prediction that provides detailed local structure information for every residue of a protein.

Determination of Mean and Standard Deviation of Dihedral Angles
Biochemical and Biophysical Research Communications, 1999Backbone torsional angles are a characteristic and useful parameter for the description and characterisation of protein structures determined by x-ray crystallography or NMR spectroscopy. For the comparison of an ensemble of three-dimensional structures the calculation of the statistical parameters mean and standard deviation would be very useful ...

Accurate measurement of the dihedral angle of a corner cube
Applied Optics, 1992The alignment of a corner cube affects the measurement of its dihedral angle. For 5 deg of tilt, the error is up to 7%, depending on the orientation of the tilt. A vector model is devised to derive formulas that take misalignment into account for both solid and hollow corner cubes. When the wave-front tilt caused by the dihedral angle error is not much

Stereology of Dihedral Angles II: Distribution Function
SIAM Journal on Applied Mathematics, 1987Summary: [For part I see the preceding review, Zbl 0637.60019.] A field of randomly dispersed dihedrals in space is sliced by a plane. This results in a field of angles in the slicing plane whose sizes A will be random, even if the original dihedrals all have the same nonrandom size \(\alpha\).

Dihedral Angle Distribution of Amorphous Germanium
TETRAHEDRALLY BONDED AMORPHOUS SEMICONDUCTORS: International Conference, 1974A theory is presented in which the radial distribution function (RDF) of an amorphous solid is considered to be the sum of a series of shells of n‐bond neighbors. Application of the theory to the structure of amorphous Ge accounts quantitatively for the experimental RDF out to a radius of 6A.

Solvability of Nonlocal Elliptic Problems in Dihedral Angles
Mathematical Notes, 2002Here the author proposes new approach to studying nonlocal problems based on the Green's formula and conjugate nonlocal problems. Such an approach allows him to remove additional constraints on the corresponding ``local'' model problem and to obtain necessary and sufficient conditions for the Fredholm solvability of nonlocal problems in plane angles ...
