A mechanism for the dependence of sunspot group tilt angles on cycle strength
(Iop Publıshıng Ltd, Temple Circus, Temple Way, Bristol Bs1 6Be, England, 2015-11-01)The average tilt angle of sunspot groups emerging throughout the solar cycle determines the net magnetic flux crossing the equator, which is correlated with the strength of the subsequent cycle. I suggest that a deep-seated, ... -
A Molecular Mechanics Conformational Study of Peptide T
(Elsevier, 1997-01-20)Conformational behaviour of peptide T, a competitor of the human immuno-deficiency virus in the binding to human T cells, was investigated by theoretical conformational analysis. Two types of conformations are found to be ... -
A Natural Limit on the Observable Periods of Anomalous X-ray Pulsars and Soft Gamma-ray Repeaters
(Amer Inst Physics, 2 Huntington Quadrangle, Ste 1No1, Melville, Ny 11747-4501 USA, 2011)We investigate the dependence of the evolution of neutron stars with fallback disks on the strength of the magnetic dipole field of the star.

A new correlation with lower kilohertz quasi-periodic oscillation frequency in the ensemble of low-mass x-ray binaries
(Iop Publishing Ltd, Temple Circus, Temple Way, Bristol Bs1 6Be, England, 2016-11-01)We study the dependence of kilohertz quasi-periodic oscillation (kHz QPO) frequency on accretion-related parameters in the ensemble of neutron-star low-mass X-ray binaries. Based on the mass accretion rate, M, and the ... -
