OBJECTIVE To analyze the effects of health reform efforts in two large states--New York and Massachusetts. DATA SOURCES/STUDY SETTING National Health Interview Survey (NHIS) data from 1999 to 2008. STUDY DESIGN We take advantage of the "natural experiments" that occurred in New York and Massachusetts to compare health insurance coverage and health care access and use for adults before and a...

BACKGROUND Randomized controlled trials (RCTs) are not always well reported, especially in terms of their methodological descriptions. This study aimed to investigate the adherence of methodological reporting complying with CONSORT and explore associated trial level variables in the Chinese nursing care field. METHODS In June 2012, we identified RCTs published in five leading Chinese nursing ...

Separation of macromolecules on the basis of their molecular weight by size exclusion chromatography has long been considered to be caused by the geometry-dependent partition of macromolecules between a continuous phase and the porous interior of a gel or cross-linked bead. The volume of a pore accessible to a solute is limited by its relative dimensions, so larger molecules will have access to...

The effective conductivities are determined for randomly oriented disklike particles using an efficient computational algorithm based on the finite element method. The pairwise intersection criteria of disks are developed using a set of vector operations. An element partition scheme has been implemented to connect the elements on different disks across the lines of intersection. The computed co...
