Continuing the work K. C. Das, I. Gutman, B. Furtula, On second geometric-arithmetic index of graphs, Iran. J. Math Chem., 1(2) (2010) 17-28, in this paper we present lower and upper bounds on the third geometric-arithmetic index GA3 and characterize the extremal graphs. Moreover, we give Nordhaus-Gaddum-type result for GA3.

We propose a new index, the j-index, which is defined for an author as the sum of the square roots of the numbers of citations to each of the author’s publications. The idea behind the j-index it to remedy a drawback of the h-index − that the h-index does not take into account the full citation record of a researcher. The square root function is motivated by our desire to avoid the possible bia...

INTRODUCTION The effect of implantable defibrillator shocks on cardiac hemodynamics is poorly understood. The purpose of this study was to test the hypothesis that ventricular defibrillator shocks adversely effect cardiac hemodynamics. METHODS AND RESULTS The cardiac index was determined by calculating the mitral valve inflow with transesophogeal Doppler during nonthoracotomy defibrillator im...

Archives of Clinical Neuropsychology, 17, 157-169] developed a method to detect malingering in chronic pain patients using seven scales from the Minnesota Multiphasic Inventory-2 (MMPI-2). This method may be impractical because two of the scales (Obvious minus Subtle and Dissimulati...
