OBJECTIVES The aim of this study was to explore the option of stimulating calf muscle contraction through externally applied neuromuscular electrical stimulation (NMES) and to measure venous blood flow response to this stimulation. METHODS Ten patients with class 6 chronic venous disease (CEAP clinical classification) were recruited. Measurements of peak venous velocities in the popliteal vei...

This paper describes a new XML compression scheme that offers both high compression ratios and short query response time. Its core is a fully reversible transform featuring substitution of every word in an XML document using a semi-dynamic dictionary, effective encoding of dictionary indices, as well as numbers, dates and times found in the document, and grouping data within the same structural...

Nowadays, we have to deal with a large quantity of unstructured data, produced by a number of sources. The application of clustering on the World Wide Web is essential to getting structured information in response to user queries. In this paper, we intend to test the results of a new clustering technique – clustering by compression – when applied to heterogeneous sets of data. The clustering by...

Novel setup and analysis method have been designed to quantify the response of mechanofluorochromic compounds compression or shearing stresses.

BACKGROUND Afterload is expected to increase with pneumatic compression of the lower extremities. There are left ventricular (LV) wall stress, which is the most important factor determining myocardial oxygen demand, will also increase, leading to an increase in the sensitivity of dobutamine stress echocardiography (DSE) or a shortened time to a positive response. METHODS AND RESULTS In 40 pat...

OBJECTIVE The structural anisotropy of articular cartilage controls its deformation response. As proteoglycans and collagen vary with depth, simple uniaxial compression results in inhomogeneous deformation with distinct depth-dependent mechanical properties. Investigations into depth-dependent mechanical properties of articular cartilage have previously required tissue modification after specim...
