Torsional Deformations in Subnanometer MoS Interconnecting Wires.

We use aberration-corrected transmission electron microscopy to track the real time atomic level torsional dynamics of subnanometer wires of MoS interconnecting monolayer regions of MoS2. An in situ heating holder is used inside the transmission electron microscope to raise the temperature of the sample to 400 °C to increase crystallization rates of the wires and reduce contamination effects. F...

Coupled extensional and torsional deformations of a piezoelectric cylinder

We derive a one-dimensional model from the three-dimensional equations to analyze electromechanical deformations of a piezoceramic cylinder. We show that its extensional and torsional deformations are coupled if the axis of polarization at a point makes a nonzero angle with the axis of the cylinder and the projection of the polarization vector on a cross section is perpendicular to the radial l...

Adaptive Space Deformations Based on Rigid Cells

We propose a new adaptive space deformation method for interactive shape modeling. A novel energy formulation based on elastically coupled volumetric cells yields intuitive detail preservation even under large deformations. By enforcing rigidity of the cells, we obtain an extremely robust numerical solver for the resulting non-linear optimization problem. Scalability is achieved using an adapti...

New Lie-Algebraic and Quadratic Deformations of Minkowski Space from Twisted Poincaré Symmetries

We consider two new classes of twisted D=4 quantum Poincaré symmetries described as the dual pairs of noncocommutative Hopf algebras. Firstly we investigate the two-parameter class of twisted Poincaré algebras which provide the Liealgebraic noncommutativity of the translations. The corresponding star-products and new deformed Lie-algebraic Minkowski spaces are introduced. We discuss further the...
