Atmospheric heterogeneous reactions can potentially change the hygroscopicity of atmospheric aerosols as they undergo chemical aging processes in the atmosphere. A particle's hygroscopicity influences its cloud condensation nuclei (CCN) properties with potential impacts on cloud formation and climate. In this study, size-selected calcite mineral particles were reacted with controlled amounts of...

In two previous papers on the infrared emission spectra of gaseous BeH2, BeD2, and MgH2 molecules, we reported rotational analyses of the antisymmetric stretching fundamental band and several hot bands. A customary effective rotational energy level expression, which is a power series in J J+1 with B v , D v , and H v constants, was used for most of the observed vibrational levels. For all the v...

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...

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.
