    NMR-Investigations of Homogeneous Hydrogenation Reactions using Para Hydrogen

    Homogeneous hydrogenations with ortho- or para-enriched hydrogen result in strongly enhanced 1H-NMR-polarization signals due to symmetry breaking during the reactions. Polarization is observed only, if the transf...

    Neo-Adjuvant chemotherapy for patients with oral and oro-pharyngeal T3/T4 carcinomas

    We presented in 1987, a randomized trial for neo-adjuvant chemotherapy before radiotherapy, called INSERM [1] trial, dealing with 14 patients with oral and oro-pharyngeal T3/T4 carcinomas. Then, we concluded t...

    Neo-Adjuvant chemotherapy in breast cancer Study of 477 evaluable patients with primary breast cancers treated between 1980 and 1992

    Neo-Adjuvant chemotherapy in breast cancer means that chemotherapy is used as the first therapeutic tool and that the locoregional treatment is considered as an adjuvant. The term has been contested and others...

    Optimal “Anti-Bayesian” Parametric Pattern Classification for the Exponential Family Using Order Statistics Criteria

    This paper reports some pioneering results in which optimal parametric classification is achieved in a counter-intuitive manner, quite opposed to the Bayesian paradigm. The paper, which builds on the results o...
