OBJECTIVES The diagnostic utility and reliability of an easy-to-operate novel handheld nerve conduction tester in carpal tunnel syndrome (CTS) were evaluated. MATERIALS AND METHODS Using the test device, the sensory nerve conductions (SNC) in the median and ulnar nerves were compared with each other in 194 patients with suspected CTS and 95 healthy controls. The test device results were compa...

Alon and Krivelevich (SIAM J. Discrete Math. 15(2): 211-227 (2002)) show that if a graph is ε-far from bipartite, then the subgraph induced by a random subset of Õ(1/ε) vertices is bipartite with high probability. We conjecture that the induced subgraph is Ω̃(ε)-far from bipartite with high probability. Gonen and Ron (RANDOM 2007) proved this conjecture in the case when the degrees of all vertic...

.\ hardness tester, especially adapted for grain, was cor~structecl by modifying a commercial portable soft metal tester known as the Barcol Impressor. h preloaded stylus is forced into grain sections preparetl by rneans ot a microtome. The displacement of the stylus, nleasured by a dial micrometer, is used as a hardness index. This has been related to tlie l'ickers tlianlontl pyramid hardness ...

This paper reports a comparative study between yarn mass and yarn diameter measurement systems using a differential capacitance tester and an optical coherent signal processing diameter tester respectively. A full description of the systems is presented along with their new contributions, namely 1mm length samples analysis for a capacitive tester and optical signal processing to eliminate the i...

An open architecture tester allows a third party to develop its own instrument. Such a tester must be open in the sense that it needs to be able to integrate this instrument with minimal or no impact on the overall performance and cost. It is therefore fundamental that the data flow and synchronization among all the instruments in an open architecture tester be efficient. One of these two key t...

In the literature ample attention is given to the assumptions on which the interpretation of shear-test results from a Jenike shear tester are based. Very little is said, however, about the influence on the test data of the construction of the apparatus itself. In the work described here, the authors have investigated the influence of the loading mechanism on the results. The original Jenike-ty...

introduction: hyperplastic pulpitis (pulp polyp)tissues contains cells with stem cell properties similar to that of the dental pulp stem cells (dpscs). it has also been shown that cd146 enrichment can homogenize the cultures of dpscs and enhance the colony forming potentials of their cultures. this study determines whether cd146 enrichment can help purifying the stem cells from heterogeneous cu...

In this paper, we provide a practical formulation of the problem of identifying all error occurrences and all failed scan cells in atspeed scan based BIST environment. We propose a method that can be used to identify every error when the circuit test frequency is higher than the tester frequency. Our approach requires very little extra hardware for diagnosis and the test application time requir...

A comparison was made between results obtained through the Titmus Vision Tester and those obtained through more common open field optometric procedures. Specific tests performed with the Titmus Vision Tester included near and distance visual acuities, distance lateral and vertical phorias, color discrimination, and stereo acuity. Results were also obtained using Snellen near and distance charts...
