Including orbital fluctuations in the noise spectrum of autonomous circuits [PDF]
, 2011 We discuss the impact of orbital fluctuations on the noise spectrum of a free-running oscillator, exploiting a rigorous nonlinear perturbative analysis based on the Floquet theory, and providing evidence of its relevance for high-Q oscillators.

Orbital leiomyosarcoma metastasis presenting prior to diagnosis of the primary tumor [PDF]
, 2017 Leiomyosarcomas, neoplasms of smooth muscle, are rarely found within the orbit. Orbital leiomyosarcoma may be primary, metastatic, or secondary to radiation. When they are metastatic, patients almost exclusively have a history of a primary leiomyosarcoma,

Congenital orbital teratoma: a case report with preservation of the globe and 18 years of follow-up
BMC Ophthalmology, 2021 Background Congenital orbital teratomas are extremely rare, usually benign neoplasms, comprised of cells originating from all three germ cell layers. Clinically the tumor appears solid, most of the times is intraconal and presents as a rapidly growing ...

Molecular Oncology, EarlyView.Drug resistance limits treatment success in a subset of lung cancers driven by ROS1 gene alterations. Using patient‐derived cells and computer simulations, we studied three key mutations and how they affect five targeted drugs. The mutations reduced drug effectiveness in different ways by altering protein structure and behavior.
