The First to be Destroyed

The Jewish community of the city of Kleczew came into existence in the sixteenth century. It remained large and strong throughout the next four hundred years, and in the eighteenth and nineteenth centuries it constituted 40-60% of the total population. The German army entered Kleczew on September 15, 1939, shortly after the outbreak of World War II. The communities of Kleczew and the vicinity were among the first Jewish collectives in Europe to be totally destroyed. The events presented in this book reveal that the organization of deportations and the methods of mass murder conducted in this district, by Kommando Lange, served as a model that would be applied later in the death camps during the mass extermination of Polish and European Jewry. If so, it was in the woods near Kleczew that the “Final Solution of the Jewish Question” began

A molecular theory for two-photon and three-photon fluorescence polarization

In the analysis of molecular structure and local order in heterogeneous samples, multiphoton excitation of fluorescence affords chemically specific information and high-resolution imaging. This report presents the results of an investigation that secures a detailed theoretical representation of the fluorescence polarization produced by one-, two-, and three-photon excitations, with orientational averaging procedures being deployed to deliver the fully disordered limits. The equations determining multiphoton fluorescence response prove to be expressible in a relatively simple, generic form, and graphs exhibit the functional form of the multiphoton fluorescence polarization. Amongst other features, the results lead to the identification of a condition under which the fluorescence produced through the concerted absorption of any number of photons becomes completely unpolarized. It is also shown that the angular variation of fluorescence intensities is reliable indicator of orientational disorder

Controllability on infinite-dimensional manifolds

Following the unified approach of A. Kriegl and P.W. Michor (1997) for a treatment of global analysis on a class of locally convex spaces known as convenient, we give a generalization of Rashevsky-Chow's theorem for control systems in regular connected manifolds modelled on convenient (infinite-dimensional) locally convex spaces which are not necessarily normable.Comment: 19 pages, 1 figur

Continuous Uniform Finite Time Stabilization of Planar Controllable Systems

Continuous homogeneous controllers are utilized in a full state feedback setting for the uniform finite time stabilization of a perturbed double integrator in the presence of uniformly decaying piecewise continuous disturbances. Semiglobal strong $\mathcal{C}^1$ Lyapunov functions are identified to establish uniform asymptotic stability of the closed-loop planar system. Uniform finite time stability is then proved by extending the homogeneity principle of discontinuous systems to the continuous case with uniformly decaying piecewise continuous nonhomogeneous disturbances. A finite upper bound on the settling time is also computed. The results extend the existing literature on homogeneity and finite time stability by both presenting uniform finite time stabilization and dealing with a broader class of nonhomogeneous disturbances for planar controllable systems while also proposing a new class of homogeneous continuous controllers

Electronic Spectra of Cyano-5-phenyltetrazoles

Absorption and luminescence spectra of ortho-, meta- and para- cyano-5-phenyltetrazole in aqueous solutions at room and low temperature were measured. Investigations wene carried out in super acidic (H; = -8) to basic (pR = 12)media. Three dissociation forms were identified (anion, molecule and cation), and the corresponding acid-base equilibrium constants in the ground state, speetrophotometrically, and in the first excited singlet state from the titration curves and by Forster cycle were determined

Analysis of robustness of homogeneous systems with time delays using Lyapunov-Krasovskii functionals

International audienceThe paper is devoted to stability analysis of homogeneous time-delay systems applying the Lyapunov-Krasovskii theory, and a generic structure of the functional is given that suits for any homogeneous system of non-zero degree (and can also be used for any dynamics admitting a homogeneous approximation). The obtained stability conditions are utilized to evaluate the domain of attraction for the delayed twisting control algorithm
