Changes in the expression profiles of microRNAs (miRNAs) have been found in many cancers. The study was aimed to investigate the expression of miR-25, miR-223, and miR-375 in the serum of patients with esophageal squamous cell carcinoma (ESCC) and its effect on survival outcome. We examined the expression levels of miR-25, miR-223, and miR-375 in 20 pairs(More)
To build a new wireless robotic capsule endoscope with external guidance for controllable and interactive GI tract examination, a sensing system is needed for tracking 3D location and 2D orientation of the capsule movement. An appropriate sensing approach is to enclose a small permanent magnet in the capsule. The magnet establishes a magnetic field around(More)
In this paper we present a continuous surface model to describe the interconnect geometric variation, which improves the currently used model for better accuracy while not increasing the number of variables. Based on it, efficient techniques are presented for chip-level capacitance extraction considering the window technique. The sparse-grid-based Hermite(More)
