Application of EEG multipole model in the diagnosis of Alzheimer''''s disease

In order to find the electroencephalogram （EEG） characteristic parameters typical of Alzheimer＇s disease （AD） and explore an effective diagnostic method, a new mobile current multipole model was proposed to simulate the AD patient＇s cortical dipole source activities. The indicators of goodness of fit （GOF） and DtononD （DD） were calculated from EEG samples to evaluate the performance of this model. Relevant results showed that this multipole model with higher GOFvalues and larger DD change well fitted the pathological electrical activities of cortical neurons aroused by AD＇s extended sulcus and gyrus in the cerebral cortex. Meanwhile, the products of DD mean ＆ standard variance were found in a clear linear correlation with the diagnostic data of mini-mental state examination （MMSE） used in AD clinics. Furthermore, by tracing this multipole model＇s indicators in typical patients and contrasting with the functional magnetic resonance image （fMRI） as AD progressed, we suggested that the DD index may be suitable for monitoring the AD developments as a new diagnostic parameter.

Using Fundamental Economic Structures to Estimate Chinese Regional Input-Output Tables

The estimation of regional input-output tables is well discussed in the literature and a large variety of methods exist. In this paper we will use the concept of fundamental economic structure （FES） to estimate the matrix of intermediate deliveries for some ＂missing＂ region（s）. Furthermore, the estimates will be compared with the estimates obtained from ＂traditional＂ estimating techniques, including regionalization on the basis of the national table, and borrowing coefficients from similar regions. The results show FES is very helpful for compiling regional tables of China.     

Recombination and linkage disequilibrium in Arabidopsis thaliana

Linkage disequilibrium (LD) is a major aspect of the organization of genetic variation in natural populations. Here we describe the genome-wide pattern of LD in a sample of 19 Arabidopsis thaliana accessions using 341,602 non-singleton SNPs. LD decays within 10 kb on average, considerably faster than previously estimated. Tag SNP selection algorithms and 'hide-the-SNP' simulations suggest that genome-wide association mapping will require only 40%-50% of the observed SNPs, a reduction similar to estimates in a sample of African Americans. An Affymetrix genotyping array containing 250,000 SNPs has been designed based on these results; we demonstrate that it should have more than adequate coverage for genome-wide association mapping. The extent of LD is highly variable, and we find clear evidence of recombination hotspots, which seem to occur preferentially in intergenic regions. LD also reflects the action of selection, and it is more extensive between nonsynonymous polymorphisms than between synonymous polymorphisms.
