Arno Van Den Essen , Roel Willems And

In this paper we prove four cases of the vanishing conjecture of differential operators with constant coefficients and also a conjecture on the Laurent polynomials with no holomorphic parts, which were proposed in [Zh3] by the third named author. We also give two examples to show that the generalizations of both the vanishing conjecture and the Duistermaat-van der Kallen theorem [DK] to Laurent...

Metabolism of hypoxanthine in isolated rat hepatocytes Marie-Franqoise VINCENT, Georges VAN DEN BERGHE and Henri-Gery HERS

1. The hepatic metabolism of hypoxanthine was investigated by studying both the fate of labelled hypoxanthine, added at micromolar concentrations to isolated rat hepatocyte suspensions, and the kinetic properties of purified hypoxanthine/guanine phosphoribosyltransferase from rat liver. 2. More than 80% of hypoxanthine was oxidized towards allantoin; less than 5% of the label was incorporated i...

Van der Corput sequences towards general ( 0 , 1 ) – sequences in base b par Henri FAURE

As a result of recent studies on unidimensional low discrepancy sequences, we can assert that the original van der Corput sequences are the worst distributed with respect to various measures of irregularities of distribution among two large families of (0, 1)–sequences, and even among all (0, 1)–sequences for the star discrepancy D∗. We show in the present paper that it is not the case for the ...
