Detecting Postural Instability in Parkinson’s Disease From IMU-Based Objective Measures
Parkinson’s Disease (PD) is a progressive neurological disorder that affects both motor and non-motor functions. A critical aspect of PD is postural instability, which is associated with a higher risk of falls and a significant decline in mobility.

Acoustomechanics of semicrystalline polymers
We develop an acoustomechanical theory for semicrystalline polymers and demonstrate that acoustic radiation force is capable of causing giant deformation in these materials.

The Pull Test: A Dynamic Test to Confirm Hip Microinstability
Purpose: To define a distraction distance (pull length) cut-off that would differentiate those patients with hip microinstability and those without the disorder, called the Pull-Out Test.

Temperature Sensitivity of Silicon Cantilevers with the Pull-in Instability Method
AbstractIn this paper the temperature effects on [110] Silicon cantilevers is analyzed and measured in the range of 25 -100 °C. The quasi-static electrostatic pull-in instability method developed recently for ultra-thin cantilevers [“Characterizing Size-dependent Effective Elastic Modulus of Silicon Nanocantilevers Using Electrostatic Pull-in ...
