On literature review, the studies on carboxylic acids reveal that their coordination chemistry has been studied extensively. However, in view of the absence of reports on the coordination chemistry of substituted acetic acid moieties the present investigation has been undertaken. In the present work, naphthalene acetic acid (NAA) a base moiety was characterized by elemental analysis, Ultra Viol...

We propose three physical tests to measure correlations in random numbers used in Monte Carlo simulations. The rst test uses autocorrelation times of certain physical quantities when the Ising model is simulated with the Wol algorithm. The second test is based on random walks, and the third on blocks of n successive numbers. We apply the tests to show that recent errors in high precision simula...

The pretectum, accessory optic system (AOS) and the vestibulocerebellum (VbC) have been implicated in the analysis of optic flow and generation of the optokinetic response. Recently, using drifting sine-wave gratings as stimuli, it has been shown that pretectal and AOS neurons exhibit spatio-temporal tuning. In this respect there are two groups: fast neurons, which prefer low spatial frequency ...
