Abstract Background Thyroid function tests (TFT) which usually include thyroid stimulating hormone (TSH), total triiodothyronine (TT3), and free thyroxine (FT4) are widely applied in clinical practice for screening, diagnosis monitoring of disease. We evaluated analytical performance TSH, TT3, FT4 using DxI800 (Beckman Coulter, USA) including comparison to Alinity I (Abbott, USA). Methods Preci...

The first bacterium to be tested by an efficient selective method for the occurrence of genetic recombination was strain K-12 of Bsche~icl~ia coli. Experiments with auxotroph mutants of this strain promptly gave conclusive, positive evidence of genetic exchanges between different mutant cells in mixed cultures (1, 2). However, subsequent attempts to obtain comparable results with a number of ot...

We discuss some aspects of the deformed W-algebras Wq,t[g]. In particular, we derive an explicit formula for the Kac determinant, and discuss the center when t is a primitive k-th root of unity. The relation of the structure of Wq,t[g] to the representation ring of the quantum affine algebra Uq(ĝ), as discovered recently by Frenkel and Reshetikhin, is further elucidated in some examples.

This paper describes a class of decentralized dynamic processes designed to converge to equilibrium when the equilibrium equations are linear. These processes can also be viewed as distributed algorithms for solving systems of linear equations, or as learning algorithms. The class includes processes that use a message space larger by one binary digit than the space in which the equilibrium exis...
