Health inequity is an important issue all around the world. The Chinese basic medical security system comprises three major insurance schemes, namely Urban Employee Basic Medical Insurance (UEBMI), Resident (URBMI), and New Cooperative Scheme (NCMS). Little research has been conducted to look into disparity in payments among health schemes China. In this study, we aimed evaluate reimbursements for tuberculosis (TB) care abovementioned schemes.This study uses a World Organization (WHO)...

Half-Heuslers emerged as promising candidates for medium- and high-temperature thermoelectric power generation. However, polycrystalline half-Heuslers inevitably suffer from the defect-dominated scattering of electrons that greatly limits optimization their electronic properties. Herein, high-quality TiCoSb-based single-crystals with a dimension above 1 cm have been obtained. Benefitting improved electron mobility, an average factor ~37 μW cm−1 K−2 in temperature range between 307 973 K has...
