Tunable mechanical coupling between driven microelectromechanical resonators

, 2016
We present a microelectromechanical system, in which a silicon beam is attached to a comb-drive actuator, that is used to tune the tension in the silicon beam, and thus its resonance frequency.

Clonal lineage of high grade serous ovarian cancer in a patient with neurofibromatosis type 1

Gynecologic Oncology Reports, 2018
Neurofibromatosis type 1 (NF1) is caused by mutations in the NF1 gene encoding neurofibromin, which negatively regulates Ras signaling. NF1 patients have an increased risk of developing early onset breast cancer, however, the association between NF1 and ...
