Evaluation of the potential functions of Avian paramyxovirus Accessory proteins
… six structural and two accessory proteins. The functions of APMV accessory proteins (V and W) are not fully established. Only the function of V protein in NDV is studied so far. V protein was found to be an IFN antgonist and a major virulent determinant of NDV. In this study, we tested for the …

Building generative models over discrete structures : from graphical models to deep learning
… perspectives: defining models via structured potential functions, and via neural network based decoders. In the first case, we investigated Perturbation Models, a family of implicit distributions where samples emerge through optimization of randomized potential functions. Designed explicitly …

Three-Dimensional Non-Axisymmetric Anisotropic Stress Concentrations
… of equilibrium in terms of three quasi-harmonic potential functions, each of which is harmonic in a space different from the physical space. Thus, three spheroidal coordinate systems with different metric scales (one for each potential) are introduced such that the three coordinate systems …

Some structural theorems for inelastic solids : an internal variable approach.
… of inelastic solids involving thermodynamic potential functions with internal variables is reviewed. Use is made of the condition for stable thermodynamic equilibrium in order to obtain dual minimum principles for the equilibrium state of a solid inelastic body. This leads to dual forms of …

Path planning using the Newtonian potential
Potential functions are used to represent the topological structure of free space in solving path planning problems because of the simplicity in the free space representation and the guidance provided by the negative gradient of the potential field in the form of repulsive forces. In this thesis, a …

Approximate inference methods for grid-structured MRFs
… that allows it to work on MRFs with very general potential functions. These changes make it possible to use any of the three algorithms on medical imaging problems. The three algorithms were then tested on simulated problems so that their accuracy and efficiency could be compared.

A Web Service for Protein Refinement and Refinement of Membrane Proteins
… tests the ability of common molecular mechanics potential functions (AMBER99/03) and a hybrid knowledge-based potential function (KB_0.1) to refine near-native structures of membrane proteins in vacuo. A web based utility for protein refinement has been developed and deployed based on the KB_0.1 …
