Determining the number of common factors is one of the most important decisions which must be made in the application of factor analysis. Several different approaches and techniques are reviewed here along with associated strengths and weaknesses. It is argued that a combination of approaches will ...
We identified variations in the number of plots, stems, and species, and the size and spatial clustering of plots as potential confounding factors liable to skew dominance and diversity results from our regional datasets and impede rigorous comparisons between them. We used sample-based rarefaction ...
There is increasing evidence that genome-wide association (GWA) studies represent a powerful approach to the identification of genes involved in common human diseases. We describe a joint GWA study (using the Affymetrix GeneChip 500K Mapping Array Set) undertaken in the British population, which has...
Male breast cancer (MBC) is a rare and poorly known disease. Germ-line mutations of BRCA2 and, to lesser extent, BRCA1 genes are the highest risk factors a... M Falchetti,R Lupi,P Rizzolo,... - 《Breast Cancer Research & Treatment》 被引量: 77发表: 2008年 加载更多来源...
cytokines and their associated inflammatory signaling pathways (e.g., JAK-STAT, NFκB, and MAP kinases), as well as other immuno-inflammatory factors such as the microglial inducible enzyme, cyclooxygenase-2 (COX-2), may play a primary role in modulating the emergence of co-morbid depression....
The present study evaluated the influence of some environmental factors on the quantity and composition of essential oil (EO) in ripe berry cones of Juniperus communis L. The berry cones were collected from juniper shrubs growing wild at five localities of north-east Slovakia during the years ...
We will now learn how to find the greatest common divisor and the lowest common multiple of two numbers from their prime factorizations. (We saw how to find the LCM directly in Lesson 23.)First, let us see how to find all the divisors of a number from its prime factors....
It is possible that firm-year observations were correlated, since factors that we did not incorporate in our analysis (e.g., management) could have remained constant across the years (Ndofor et al., 2011). Furthermore, institutional ownership is highly “sticky” and usually does not change ...

Genetic factors modifying the blood metabolome have been investigated through genome-wide association studies (GWAS) of common genetic variants and through exome sequencing. We conducted a whole-genome sequencing study of common, low-frequency and rare variants to associate genetic variations with blood...
