Silicon Microdisk Resonators for Nonlinear Optics and Dynamics [PDF]

, 2009
Silicon is incredibly well-studied as an electronic material. Since the out-migration of William Noyce, Gordon Moore, and the rest of the original Fairchild Semiconductor class from Shockley Semiconductor, silicon has only grown in prominence.

Stimulated terahertz emission due to electronic Raman scattering in silicon [PDF]

, 2009
Silicon-based semiconductors are intensively investigated over the past years as promising candidates for optoelectronic devices at terahertz (THz) frequencies [1]. Optically pumped intracenter silicon lasers, realized in the past decade in the THz range,

Correlation of Scale Factor Non-Linearity and Vibration Rectification Error in Vibrating Beam Accelerometers

IEEE Access
Vibration Rectification Error (VRE) is a critical parameter for high-performance accelerometers operating in dynamic environments. This paper presents a focused experimental study to rigorously investigate the relationship between VRE and Scale Factor ...

Bridging the gap: a genetically validated avian chorioallantoic membrane platform for investigation of spontaneous circulating tumor cells

Molecular Oncology, EarlyView.
We established the avian chorioallantoic membrane (CAM) assay as a scalable in vivo model for studying circulating tumor cells (CTCs). Human gastrointestinal tumors spontaneously released genetically validated CTCs that were detected across multiple platforms, demonstrating that the CAM model provides an accessible tool for investigating early cancer ...
