BACKGROUND/AIMS Recent research has attempted combinations of instruments to improve screening accuracy for mild cognitive impairment (MCI) and early Alzheimer's disease (AD). We compared Mini-Mental State Examination (MMSE), Immediate and Delayed Recall (Logical Memory I and II; LM-I and LM-II, respectively), a single-item informant report of memory(More)
Based on the complexity of mechanism and variation rules of thermal error on CNC machine, a new grey system model GM(1,1,α) combined with particle swarm optimization (PSO) was proposed and applied in thermal error modeling on CNC machine. Particle swarm optimization has very strong capacity to solve complicated multi-peaked optimum question. In the(More)
Two new mariner transposon delivery vector systems, pMarA333 and pMarB333, had been constructed to randomly mutagenize Bacillus thuringiensis in vivo. The results showed that both systems could randomly insert into the genome of B. thuringiensis YBT881 (CCAM 020673). These systems could have potential for further construction of mutant libraries of B.(More)
