The function decomposition problem can be stated as: Given the algebraic expression of the composition of two mappings, how can we identify the two factors? This problem is believed to be in general intractable [1]. Based on this belief, J. Patarin and L. Goubin designed a new family of candidates for public key cryptography, the so called \2R schemes" [10, 11]. The public key of a \2R"-scheme ...

BACKGROUND Epstein-Barr virus (EBV) infection in infectious mononucleosis (IM) is associated with lymphocyte activation leading to the expansion of cells expressing activation-associated antigens. Most of these antigens are released as soluble molecules in vitro and in vivo. METHODS We investigated the serum levels of the soluble forms of the CD8 (sCD8), p55-IL-2R alpha (sIL-2R alpha), and CD...

PURPOSE We evaluated the clinical usefulness of interleukin-18 (IL-18) and soluble interleukin-2 receptor (sIL-2R) during chemotherapy of lung cancer in relation to the histological type of the tumor, clinical stage, response to therapy and time survival. MATERIAL AND METHODS Serum levels of IL-18 and sIL-2R were determined in 73 patients (62 males; mean age 64 years; 41 with non-small cell l...

We develop a method to build new 5D N=1 gauge models based on Sasaki-Einstein manifolds Yp,q. These extend the standard ones having unitary SU(p)q symmetry Particular focus is put building of family with symplectic SP(2r,R) symmetry. super QFTs are embedded in M-theory compactified folded toric Calabi-Yau threefolds Xˆ(Y2r,0) constructed from conical Y2r,0. By using outer-automorphism symmetrie...

Background: All To enhance the curative effect of radiotherapy, we established a radio-resistant cell line, CNE-2R from CNE-2, a radio-sensitive type of CNE, through repeated irradiation. The developed cell line provides a basis for further studies on the radio-resistance of CNE and the molecular mechanism of radiotherapy sensitization drugs. Materials and Methods: The CNE-2 cell line was selec...

The hemilabile chiral C2 symmetrical bidentate substituted amide ligands (1R,2R)-5(a-d) and (1S,2S)-6(a-d) were synthesized in quantitative yield from (1R,2R)-(+)-3-methylenecyclo-propane-1,2-dicarboxylic acid (1R,2R)-3 and (1S,2S)-(-)-3-methylene-cyclopropane-1,2-dicarboxylic acid (1S,2S)-3, in two steps, respectively. The chiral Feist's acids (1R,2R)-3 and (1S,2S)-3 were obtained in good isom...

Blocked designs are useful in experiments. The general minimum lower order confounding (GMC) is an elaborate criterion which was proposed for selecting optimal fractional factorial designs. Zhang and Mukerjee (2009b) extended the GMC criterion to the B-GMC criterion for selecting a 2n−m : 2r design, where 2n−m : 2r denotes a two-level regular blocked design withN = 2n−m runs, n treatment factor...
