Some lower bounds of centered $$L_2$$ L 2 -discrepancy of $$2^{s-k}$$ 2 s - k designs and their complementary designs

Abstract

The indicator function is an effective tool in studying factorial designs. This paper presents some lower bounds of centered L 2 -discrepancy through indicator function. Some new lower bounds of centered L 2 -discrepancy for 2 s−k designs and their complementary designs are given. Numerical results show that our lower bounds are tight and better than the existing results.

Comparative In Vitro Osteoinductivity Study of HA and α‐TCP/HA Bicalcium Phosphate

“…10,13,14 HA transformation during high-temperature processing comprises two reactions: dehydroxylation and decomposition. In HA dehydroxylation, HA gradually loses OH À at elevated temperatures and turns to oxyhydroxyapatite (OHA) 15,16 through Eq. (1).…”
