Hadron calorimeter (HCAL) is an essential sub-detector of the baseline detector system for Circular Electron Positron Collider (CEPC). We plan to build Analog CALorimeter (AHCAL) prototype based on Particle Flow Algorithm (PFA). The AHCAL CEPC uses steel as absorber and scintillator tiles read out by Silicon Photo-Multipliers (SiPMs) sensitive medium. energy linearity resolution depends light y...

OBJECTIVE To evaluate the pharmaceutical equivalence of a test formulation (fixed-dose combination of budesonide and formoterol fumarate in a single capsule dispensed in an Aerocaps® inhaler) in relation to a reference formulation (budesonide and formoterol fumarate in two separate capsules dispensed in an Aerolizer® inhaler). METHODS This was an in vitro study in which we performed the ident...

Abstract Helicon plasma sources are known to be efficient generators of high-density plasma for materials processing applications. By using multiple sources, arbitrarily large substrates can in principle be covered uniformly with dense plasma. To test this idea, a seven-tube helicon source was constructed, and the plasma density and uniformity measured. Densities up to 1012 cm−3 over a 40 cm di...

BACKGROUND AND PURPOSE It is estimated that one third of the institutes applying clinical beta sources does not perform independent dosimetry. The Netherlands commission on radiation dosimetry (NCS) recently published recommended quality control procedures and detectors for the dosimetry of beta sources. The main issues of NCS Report 14 are summarized here. MATERIALS AND METHODS A dosimetry s...

A recent paper in Neurology used statistical techniques to investigate the integrity of the randomization in 33 clinical trials conducted by a group of investigators. Without justification, the approach assumed that there would be no impact of correlation among baseline variables. We investigated the impact of correlation on the conclusions of the approach in several large-scale simulation stud...
