Important biological and clinical features of malignancy are reflected in its transcript pattern. Recent advances in gene expression technology and informatics have provided a powerful new means to obtain and interpret these expression patterns. A comprehensive approach to expression profiling is serial analysis of gene expression (SAGE), which provides digital information on transcript levels....

A novel and deterministic algorithm is presented to detect whether two given rational plane curves are related by means of a similarity, which is a central question in Pattern Recognition. As a by-product it finds all such similarities, and the particular case of equal curves yields all symmetries. A complete theoretical description of the method is provided, and the method has been implemented...

Objectives: In traditional medicine Salvia officinalis (sage) has been used as menstrual cycle regulator. In the present study the effects of sage extract on breast tissue were examined. Materials and Methods: Fourteen female rats were divided into two groups: 1) Distilled water-treated rats (Con) that were gavaged with 1ml distilled water and 2) Saliva officinalis hydroalcoholic extract (SHE)-...

As conventional methods deal with channel estimation and synchronization separately, they can’t achieve the best performances because the unknown parameters will interfere with each other. Besides, the convergence speed is slow using expectation maximization algorithm. Thus in this paper, we propose a joint synchronization and channel estimation method in MIMO-OFDM systems. The algorithm achiev...

GENETICS, SOCIAL SCIENCES Retraction for ‘‘PKNOX2 gene is significantly associated with substance dependence in European-origin women,’’ by Xiang Chen, Kelly Cho, Burton H. Singer, and Heping Zhang, which published online August 31, 2009, in Proc Natl Acad Sci USA (10.1073/pnas.0908521106). The authors wish to retract this paper because its publication violates the Gene Environment Association ...

this experiment was conducted in 2012 at the research field of alborz research station, research institute of forests and rangelands, karaj, iran, to study the effect of chemical and biological fertilizers on sage (salvia officinalis l.) and replacing biofertilizers instead of high doses of chemical fertilizers. the experiment was conducted in factorial in the form of a randomized complete bloc...

We present a new algorithm for penalized-likelihood emission image reconstruction. The algorithm monotonically increases the objective function, converges globally to the unique maximizer, and easily accommodates the nonnegativity constraint and nonquadratic but convex penalty functions. The algorithm is based on finding paraboloidal surrogate functions for the log-likelihood at each iteration:...
