Spot-Scan Imaging in Transmission Electron Microscopy
Science, 1991The determination of the structure of proteins and other organic materials by transmission electron microscopy is a rapidly developing field. Obtaining high-resolution images of these radiation-sensitive specimens has, until recently, been problematic. The development of spot-scan imaging, in which the electron beam is focused to a spot with a diameter

Language Independent Word Spotting in Scanned Documents
2008Large quantities of scanned handwritten and printed documents are rapidly being made available for use by information storage and retrieval systems, such as for use by libraries. We present the design and performance of a language independent system for spotting handwritten/printed words in scanned document images. The technique is evaluated with three

Scanning spot beam satellite for domestic service
8th Communications Satellite Systems Conference, 1980This paper reports the progress and experimental efforts toward the realization of a high-capacity, scanningspot-beam satellite for domestic service. An experimental 12-GHz phased-array transponder was constructed which achieves rapid beam switching and the cophasing of all the array elements toward widely spaced receiving stations.

Optimizing spot‐scanning proton arc therapy with a novel spot sparsity approach
Medical PhysicsAbstract Background One of the main challenges of utilizing spot‐scanning proton arc therapy (SPArc) in routine clinics is treatment delivery efficiency. Spot reduction, which relies on spot sparsity optimization (SSO), is crucial for achieving high delivery efficiency in SPArc.
