A nonlinear conjugate gradient algorithm which is a modification of the Dai and Yuan [Y.H. Dai and Y, Yuan, A nonlinear conjugate gradient method with a strong global convergence property, SIAM J. Optim., 10 (1999), pp.177-182.] conjugate gradient algorithm satisfying a parametrized sufficient descent condition with a parameter k δ is proposed. The parameter k δ is computed by means of the conj...

Haemophilus influenzae, a major cause of meningitis in young children leading to death and other neurological sequelae. The disease leaves 15 to 35% of the survivors with permanent disabilities, such as, mental retardation or deafness. Despite the availability of new and more powerful antibiotics children with Hib meningitis still suffer from high mortality or morbidity. The emergence of multir...

In the class of strictly convex smooth boundaries each which has no strip around its boundary foliated by invariant curves, we prove that Taylor coefficients “normalized” Mather’s $$\beta$$ -function are under $$C^{\infty}$$ -conjugacies. contrast, any two elliptic billiard maps $$C^{0}$$ -conjugate near their respective boundaries, and -conjugate, away from a line passing through center underl...

Introduction: The determination of patient’s absorbed dose is the first step of radiation protection which depends on the quantification of organ activity in nuclear medicine. The aim of the present study was to determine the absorbed dose by patient’s uterus following myocardial perfusion scan with 99mTC-sestamibi using Theroluminescnce dosimetry (TLD) and conjugate-view metho...

Protonation of the highly reactive 1:1 intermediates, produced in the reaction between triphenylphosphine and acetylenic esters, by NH-acids such as azathioprine, imidazole or theophylline leads to the formation of vinyltriphenylphosphonium salts, which undergo a Michael addition reaction with a conjugate base to produce phosphorus ylides. Silica nanoparticles (silica NPs were prepared by therm...

We demonstrate one-to-one pixel–matching of phase–conjugate digital volume holographic data storage, with data pages as large as a megapel (1024 × 1024 pixels). A self–pumped phase–conjugate mirror in BaTiO3 is used to provide a phase–conjugate reference beam, which reconstructs the data–bearing object beam from a LiNbO3:Fe crystal using the 90◦ geometry. The systems tradeoffs of phase–conjugat...

Ciphers y = C(x, k) and  = (, ) are isomorphic if there exists invertible computable in both directions map y ↔ , x ↔ , k ↔ . Cipher is vulnerable if and only if isomorphic cipher is vulnerable. Instead of computing the key of a cipher it is sufficient to find suitable isomorphic cipher and compute its key. If φ is arbitrary substitution and T is round substitution, its conjugate  = φTφ...

Synthesis of a neomycin-Hoechst 33258 conjugate is reported. The conjugate combines the ligands known to selectively bind in the duplex and the triplex groove. The conjugate stabilizes DNA duplex over DNA triplex. The conjugate selectively stabilizes the DNA duplex (in the presence of salt), with as little as 2 muM of the ligand leading to a DeltaTm of 25 degrees C.

Spatial correlations of total electron content (TEC) variability are compared among two SAMI3 model runs and Jet Propulsion Laboratory Global Ionospheric Maps (JPL/GIM). Individual monthly correlation maps constructed with Equatorial reference points at 12 evenly spaced longitudes universal times. TEC composite (TCCs) then calculated by averaging the individual maps, shifted zonally to synchron...
