In this paper, first we present A Matlab toolbox which gives the possibility to simulate the data for testing the algorithms such as: Principal Component Analysis (PCA), Factor Analysis(FA), Independent Component Analysis (ICA), Linear Discriminant Analysis (LDA) and many other classification methods which can be used in Data Reduction (DR), Data Visualization (DV), supervised and unsupervised ...

The backfilling of lime soil in ultra-deep and ultra-narrow foundation trenches is a difficult construction link, ordinary-cemented has drawbacks, including poor strength, impermeability, frost resistance. To solve these problems, fly ash (FA)–water glass (WG)-composite-cemented developed based on background project. three-factor orthogonal tests are conducted the unconfined compressive strengt...

background: dental cobalt base alloys are biocompatible dental materials and have been widely used in dentistry. however, metals are bioinert and may not present bioactivity in human body. bioactivity is the especial ability to interact with human body and make a bonding to soft and hard tissues. the aim of the present research was fabrication and bioactivity evaluation of novel cobalt alloy/ f...

To investigate the molecular mechanism underlying folic acid (FA)-induced anti-colon caner activity, we showed that FA caused G0/G1 arrest in COLO-205. FA activated the proto-oncogene tyrosine-protein kinase Src (c-SRC)-mediated signaling pathway to enhance nuclear factor of kappa light polypeptide gene enhancer in B-cells (NFκB) nuclear translocation and binding onto the tumor protein p53 (TP5...

BACKGROUND AND PURPOSE Diffusion tensor imaging (DTI) will show abnormal fractional anisotropy (FA) in the normal-appearing brain after prophylactic cranial irradiation (PCI). These abnormalities will be more accentuated in patients with underlying vascular risk factors. MATERIALS AND METHODS A prospective study by use of DTI and conventional T2-weighted MR images was performed with a 1.5T un...

Administration of citrovorum factor (CF) or pteroylglutamic acid (FA) may reduce the lethal toxicity for mice of the antimetabolite 4-aminopteroylglutamic acid (aminopterin). The mortality response is dependent upon the relative dose level of FA or CF administered with the aminopterin and is influenced by the temporal relationships of administration of the drugs (1, 8-12). Administration of FA ...

FA (Fanconi anaemia) is a hereditary disease characterized by congenital malformations, progressive bone marrow failure and an extraordinary elevated predisposition to develop cancer. In the present manuscript we describe an anomalous high level of the proinflammatory cytokine IL-1beta (interleukin-1beta) present in the serum of FA patients. The elevated levels of IL-1beta were completely rever...

This paper presents a novel approach for complex disease prediction that we have developed, exemplified by a study on risk of coronary artery disease (CAD). This multi-disciplinary approach straddles fields of microarray technology and genetics, neural networks (NN), data mining and machine learning, as well as traditional statistical analysis techniques, namely principal components analysis (P...

The gas chromatographic properties of four derivatives of fatty acids (FA), namely fatty acid methyl esters, picolinyl esters, N-acyl pyrrolidides and 4,4-dimethyloxazoline derivatives, which contain various structural features (double bonds, branching, hydroxyl group) in their acyl chains have been compared on a low-polarity capillary column with a mass spectrometer as detector. Temperature pr...

Environmetric techniques such as cluster analysis (CA), principal component analysis (PCA), factor analysis (FA) and discriminant analysis (DA) were applied for the assessment of spatial and temporal variations of a large complex water quality data set of the Songkhram River Basin, generated during 15 years (1995–2009) by monitoring of 17 parameters at 5 different sites. Hierarchical CA grouped...
