— Given an intersection of two quadrics X ⊂ Pm−1, with m > 9, the quantitative arithmetic of the set X(Q) is investigated under the assumption that the singular locus of X consists of a pair of conjugate singular points defined over Q(i).

The efficacy of methotrexate (MTX) as an antimetabolite chemotherapeutic agent highly depends on its blood circulation half-life. In our previous study, different conjugates of MTX (MTX-PEG) were synthesized, their physicochemical properties were investigated and MTX-PEG5000 was finally selected as optimum drug-conjugate for further investigations. In the current work, first the stability of MT...

In this paper, the conjugate direction method is used in designing a type of iterative learning control scheme for a kind of linear discrete time-invariant single-inputsingle-output systems, which is termed as a conjugate direction method based iterative learning control scheme. The convergence of the proposed learning scheme is analyzed by the technique of inductive inference in considering th...

We prove that differentials of lattice coordinate functions x must be algebraically independent of their involutive conjugate, else no correct continuum limit exists. PACS: 02.40.Gh, 11.15.Ha

A fluorescent metallointercalator conjugate that selectively targets DNA base mismatches has been synthesized by coupling an organic fluorophore to a bulky Rh intercalator containing the chrysenequinone diimine ligand. Ion pairing between the cationic Rh and anionic fluorophore moieties dramatically quenches the fluorescence of the conjugate in solution and in the presence of matched DNA. Howev...

Frequency domain formulations of computational electromagnetic problems often require the solutions of complex-valued non-Hermitian systems of equations, which are still symmetric. For this kind of problems a whole class of sub-variant solver methods derived from the complex-valued Bi-Conjugate Gradient method is available. This class of methods contains established solution methods as the Conj...
