A hybrid symbolic-numerical approach to the center-focus problem
(2017-09-01)
We propose a new hybrid symbolic-numerical approach to the center-focus problem. The method allowed us to obtain center conditions for a three-dimensional system of differential equations, which was previously not possible ...
Thermoluminescence in Lapis Lazuli crystal: Glow peaks and their connection with F-centers estimated by ESR analysis
(Elsevier Science Bv, 2017)
The mineral Lapis Lazuli exhibits three thermoluminescence (TL) peaks approximately at 140, 260 and 370 degrees C. The TL intensity of the three peaks grows with radiation dose and it saturates only beyond 9 kGy. Electron ...

Limit cycles bifurcating from the periodic annulus of cubic homogeneous polynomial centers
(2015-10-21)
We obtain an explicit polynomial whose simple positive real roots provide the limit cycles which bifurcate from the periodic orbits of any cubic homogeneous polynomial center when it is perturbed inside the class of all ...
Trichloro-bridged diruthenium (III,III) complexes: X-ray isomorphous structures of [Ph3X=O center dot center dot center dot H center dot center dot center dot O=XPh3][Ru2Cl7(XPh3)(2)]center dot 0.5(CH2Cl2)(H2O)(X = As or P)
(Kluwer Academic Publ, 2002-01-01)
The triply chloro-bridged binuclear complexes [Ph3X=O...H...O=XPh3][Ru2Cl7(XPh3)(2)].0.5(CH2Cl2) (H2O) (X = As or P) were obtained from [RuCl3(XPh3)(2)DMA].DMA (DMA = dimethylacetamide) CH2Cl2/Et2O solution. The structures ...
