In this study we want to test whether a simple modeling procedure used in the field of QSAR/QSPR can produce simple models that will be, at the same time, as accurate as robust Neural Network Ensemble (NNE) ones. We present results of application of two procedures for generating/selecting simple linear and nonlinear multiregression (MR) models: (1) method(More)
Improved models for predicting viscosities at 20 °C were generated using three different methods for descriptor selection. Data set of 361 diverse organic molecules and their experimental viscosities were used for developing the models. Molecular properties are encoded by 822 initial descriptors computed by the CODESSA program. CODESSA, GFA and CROMRsel(More)
Experiments were designed to investigate whether the tumor-associ ated macrophage (TAM) content of murine solid tumors correlates with the clonogenic ability of tumor cells to establish s.c. tumors, tumor growth rate, extent of tumor necrosis, tumor metastatic propensity, and tumor radioresponse. Of 13 tumors studied, 6 were sarcomas and 7 were carcinomas;(More)
We present a method which provides some information on the possible binary nature of an apparently single star. The method compares the instantaneously measured HIP-PARCOS proper motion with the long-term averaged, ground-based proper motion or with the proper motion derived from old ground-based positions and the HIPPARCOS position. Good sources for such(More)
We consider multiple resonance scattering with complete frequency redistribution (CFR) in a semi-infinite conservative atmosphere (photon destruction probability ε I = 0) with the sources at infinite depth. The polarization arising in resonance scattering is completely accounted for. The problem we consider is the resonance-scattering counterpart of the(More)
