Effect of contact geometry on the contact stresses in a flat with rounded edge contact
The blade-disc dovetail interface in an aero-engine compressor is characterized by a non-uniform pressure distribution which can be obtained by an equivalent flat with rounded edge-on-plate configuration.

Contact Stress Analysis of Traction Drives of a New Type Bearing Reducer
An arc is constructed at the end of the planetary wheel profile shaft of the planetary traction drive, and the contact point between the arc and the outer ring and the end face of the solar wheel shaft is kept on the radial traction contact line.

Equilibration of quantum Hall edge states by an Ohmic contact
Ohmic contacts are crucial elements of electron optics that have not received a clear theoretical description yet. We propose a model of an Ohmic contact as a piece of metal of the finite capacitance $C$ attached to a quantum Hall edge.

Spin current in an electron waveguide tunnel-coupled to topological insulator
We show that electron tunneling from edge states in two-dimensional topological insulator into a parallel electron waveguide leads to the appearance of spin-polarized current in the waveguide.

Where is the Inner Edge of an Accretion Disk Around a Black Hole? [PDF]
What is meant by the "inner edge" of an accretion disk around a black hole depends on the property that defines the edge. We discuss four such definitions using data from recent high-resolution numerical simulations.

When is visual information used to control locomotion when descending a kerb? [PDF]
BACKGROUND: Descending kerbs during locomotion involves the regulation of appropriate foot placement before the kerb-edge and foot clearance over it. It also involves the modulation of gait output to ensure the body-mass is safely and smoothly lowered to

Ultra Low Specific Contact Resistivity in Metal-Graphene Junctions via Atomic Orbital Engineering
A systematic investigation of graphene edge contacts is provided. Intentionally patterning monolayer graphene at the contact region creates well-defined edge contacts that lead to a 67% enhancement in current injection from a gold contact.
