Abstract Background A motor unit (MU) is formed by a single alpha motor neuron (MN) and the muscle fibers it innervates. The MU is essential for all voluntary movements. Functional deficits in the MU result in neuromuscular disorders (NMDs). The path

The authors use resonant wireless power transfer to remotely trap and release nanoparticles in solution and detect their presence as a shift in impedance in real-time. This is accomplished using the extreme field confinement of a nanogap capacitor.

Nonlocality is typically studied in simplified 2D or symmetric 3D structures and the ability to perform nonlocal simulations for complex 3D structures is lacking. Here the authors examine non-local optical effects in small gaps and its effect on the
