Miniature magnetic rod interfacial stress rheometer for general-purpose microscopes

Point-of-Care Pathology with Miniature Microscopes

Advances in optical designs are enabling the development of miniature microscopes that can examine tissue in situ for early anatomic and molecular indicators of disease, in real time, and at cellular resolution. These new devices will lead to major changes in how diseases are detected and managed, driving a shift from today's diagnostic paradigm of biopsy followed by histopathology and recommen...

Stress-Testing General Purpose Digital Library Software

DSpace, Fedora, and Greenstone are three widely used open source digital library systems. In this paper we report on scalability tests performed on these tools by ourselves and others. These range from repositories populated with synthetically produced data to real world deployment with content measured in millions of items. A case study is presented that details how one of the systems performe...

General-Purpose Computation without General-Purpose Processors

General Purpose Work Flow Languages General Purpose Work Flow Languages *

Work ow management requires language support for work ow speciication and task speciication. Many approaches and systems for work ow managementtherefore ooer at least one new language for work ow speciication; task speciication is usually done in a traditional language. This is motivated in particular by the fact that many components already exist and the task of the work ow tool is the speciic...

Development of an atomic-force-microscope-based hanging-fiber rheometer for interfacial microrheology.

A new interfacial microrheology technique using atomic force microscope (AFM) as a force sensor is developed. The probe used for microrheology contains a long vertical glass fiber with one end glued onto a rectangular shaped cantilever beam and the other end immersed through a water-air interface. The motion of the modified cantilever can be accurately described by the Langevin equation for a d...
