In this paper, we analyze tactical conflicts between attacking formations and blocking formations in the phase of reception attack in volleyball, using a zerosum game model. In this model, we categorize the attacking formations into 9 patterns which consist of 3 moving patterns of forward players and 3 positions (right, center and left) from which the ball can be spiked. We also categorize the ...

Objective: Resistance of metastatic lymph nodes (LNs) to high dose I-131 therapy is associated with high morbidity in patients with differentiated thyroid cancer. We evaluated the role of F-18 FDG PET/CT in the prediction of resistance to high dose I-131 therapy in patients with papillary thyroid cancer. Methods: The subjects were 307 patients who underwent total or near total thyroidectomy fol...

An (r, s)-formation is a concatenation of s permutations of r letters. If u is a sequence with r distinct letters, then let Ex (u, n) be the maximum length of any r-sparse sequence with n distinct letters which has no subsequence isomorphic to u. For every sequence u define fw(u), the formation width of u, to be the minimum s for which there exists r such that there is a subsequence isomorphic ...

A multi-robot formation composed of autonomous agents may need to maintain an overall rigid shape for tasks such as collective transport of an object. To distribute control, we construct leader-follow formations in the plane that are persistent: designated “leader” robots control the movement of the entire formation, while the remaining “follower” robots maintain directed local links sensing da...

A number of techniques that allow autonomous multi-robot systems to be held within formation-like structures exist but they are limited by a high communication load, high energy usage and a lack of robustness. This research improves on state-of-the-art formation control schemes for leader-follower type multi-robot systems by employing mechanisms that enable groups of robots to move in two-dimen...

A retrospective study of radiolodine therapy for thyrotoxicosis was done in 402 patients over a period of 10 years from 1963 to 1972. The patients were classified as follows: (1) Age (2) Sex (3) Size of the gland estimated by physical exmination (4) Type of goitre (diffuse, nodular) (5) Ocular signs (6) Number of doses and (7) Total dose of 1-13 1 administered. The usual age for the treatment w...

VP22, encoded by the UL49 gene of Marek's disease virus (MDV), is indispensable for virus cell-to-cell spreading. We show herein that MDV UL49 can be functionally replaced with avian and human viral orthologs. Replacement of MDV VP22 with that of avian gallid herpesvirus 3 or herpesvirus of turkey, whose residue identity with MDV is close to 60%, resulted in 73 and 131% changes in viral spreadi...

this study was done in research institute of nuclear medicine from 1988-1992 for evaluation of the value of serum thyroglobulin level in comparison with 1-131 whole body scan (1-131 wbs) in patients with differentiated thyroid carcinoma. 204 patients who had total or near total thyroidectomy treated with 1-131 were evaluated in this study. out of 204 patients 136 did not have regional or distan...

The individual feathers in the skin of a developing chicken embryo are arranged in a precise array within a series of so-called 'tracts'. The images above show nascent feather buds in the legs of embryos at 8–9 days of incubation. Buds are added sequentially across the forming feather tract, as shown by the range of developmental stages in the image at top left. (In all three upper images, buds...
