In this paper, we present some new applications of the bounds for the differential probability of a SDS (Substitution-Diffusion-Substitution) structure by Park et al. at FSE 2003. Park et al. have applied their result on the AES cipher which uses the SDS structure based on MDS matrices. We shall apply their result to practical ciphers that use SDS structures based on {0, 1}-matrices of size n×n...

Class A G-protein-coupled receptors (GPCRs) provide a fascinating example of evolutionary success. In this review, we discuss how metric multidimensional scaling (MDS), a multivariate analysis method, complements traditional tree-based phylogenetic methods and helps decipher the mechanisms that drove the evolution of class A GPCRs. MDS provides low-dimensional representations of a distance matr...

The term ‘Multidimensional Scaling’ or MDS is used in two essentially different ways in statistics (de Leeuw & Heiser 1980a). MDS in the wide sense refers to any technique that produces a multidimensional geometric representation of data, where quantitative or qualitative relationships in the data are made to correspond with geometric relationships in the representation. MDS in the narrow sense...

background: the aim of this study was to determine the prevalence and characteristics of rheumatologic manifestations associated with mds. methods: eighty patients with mds were evaluated by history and physical examination for inflammatory rheumatologic disorders from jan 2013 to may 2014. patients who had any signs or symptoms of rheumatologic disorders underwent evaluation by laboratory test...

background: myelodysplastic syndromes (mdss) include a diverse group of clonal bone marrow disorders characterized by ineffective hematopoiesis and pancytopenia.it was found that down regulation of apaf1, a putative tumor suppressor gene (tsg),leads to resistance to chemotherapy and disease development in some cancers. in this study, we investigated the relation of apaf1 methylation status with...

Linear methods yield data points xn = r1φn,1 +r ∗ 2φn,2 + . . .+ rMφn,M = R φn, which are d-dimensional linear combinations of the original D-dimensional data points φn. . Principal Component Analysis (PCA, Jolliffe (2002)): Preserves the global covariance structure by decomposition of the covariance matrix Σφ,φ = RS R. . Metric Multidimensional Scaling (MDS, Cox & Cox (1994)): Preserves inner ...

Influenza viruses have been responsible for large losses of lives around the world and continue to present a great public health challenge. Antigenic characterization based on hemagglutination inhibition (HI) assay is one of the routine procedures for influenza vaccine strain selection. However, HI assay is only a crude experiment reflecting the antigenic correlations among testing antigens (vi...

myelodysplastic syndromes (mds) are a group of hematological disorders ranging from chronic refractory anemia to leukemia. there are some reports about association of mds with autoimmune disorders and vasculitis. in this study we describe a patient with mds and vasculitis presenting with central nervous system (cns) involvement. a clinical response to immunosuppressive therapy was also observed...
