BACKGROUND Toxoplasma gondii can infect all warm-blooded animals. Modified agglutination test (MAT) and ELISA are widely used for the detection of T. gondii antibodies. However, there is little information on their acceptability for detecting antibodies in companion animals. METHODS This study compared ELISA and MAT for their ability to detect T. gondii infection in naturally infected dogs an...

In order to improve the bearing capacity of soft ground for the purpose of getting trafficability of construction vehicles, the reinforcement of geosynthetics for sand-mat layers on soft ground has often been used. As the strength of the geosynthetics increases, and the sand-mat system becomes stronger, the bearing capacity of sand-mat systems will be increased. The depths of geosynthetics, rei...

A variety of data structures such as inverted file, multi-lists, quad tree, k-d tree. range tree. polygon tree, quintary tree. multidimensional tries, segment tree. doubly chained tree. the grid file. d-fold tree, super B-tree, Multiple .4ttribute Tree (MAT). etc. have been studied for multidimensional searching and related problems. Physical data base organization, which is an important applic...

Mating type genes are central to sexual reproduction and compatibility in Ascomycete fungi. However the "MAT" loci experience unique evolutionary pressures that can result in rapid divergence and enhanced inter-specific gene-flow (lateral gene transfer). In this study, molecular evolution of MAT loci was considered using the genus Fusarium (Teleomorph: Gibberella) as a model. Both MAT1-1 and MA...

We develop an O(n2) time serial algorithm to obtain the medial axis transform (MAT) of an n×n image. An O(logn) PRAM and an O(log2n) hypercube parallel algorithm for the MAT are also developed. Both of these use O(n2) processors. Two problems associated with the MAT are also studied. These are the area and perimeter reporting problem. We develop an O(logn) time hypercube algorithm for both of t...

Sera from (259) sheep and (88) goats from Erbil city were examined for antibodies to Toxoplasma gondii by using latex, MAT, and ELISA. By using latex test, 75 (25.4%) sheep and 25 (28.4%) goats were seropositive. By testing the latex seropositive sheep serum by both MAT and ELISA the distribution of both positive and negative results were as such respectively: 63 (84%), 12 (16%), 11 (14.7%), 64...

We read the article by Dutta et al on “Leptospirosis An Overview” with interest.1 The problem in utilizing microscopic agglutination test (MAT) has been highlighted and we shall discuss briefly the current status of MAT. MAT is considered the gold standard test for diagnosis of leptospirosis. It has unsurpassed specificity, but its sensitivity is low compared to ELISA/SAT (Slide agglutination t...

Multidimensional adaptive testing (MAT) is a highly efficient method for the simultaneous measurement of several latent traits. Currently, no psychometrically sound approach is available for the use of MAT in testlet-based tests. Testlets are sets of items sharing a common stimulus such as a graph or a text. They are frequently used in large operational testing programs like TOEFL, PISA, PIRLS,...

Our objective in this study was to characterize prokaryotic sulphide production within the oxygenic, predominantly eukaryotic algal mat in an acidic stream, Nymph Creek, in Yellowstone National Park (YNP). We used microsensors to examine fluctuations in H2S and O2 concentrations over time through the vertical aspect of the approximately 3 mm mat in a 46-48 degrees C region of the creek. We also...

MOTIVATION Individual probes on an Affymetrix tiling array usually behave differently. Modeling and removing these probe effects are critical for detecting signals from the array data. Current data processing techniques either require control samples or use probe sequences to model probe-specific variability, such as with MAT. Although the MAT approach can be applied without control samples, re...
