The main purpose of this work has been to investigate the fundamental dynamics of photodissociation and photo-induced isomerization reactions in the condensed phase. These "elementary" reactions have been chosen as model processes for exploring the influence of the solvent on a chemical event, as well as the factors that control this influence. Femtosecond laser spectroscopy has been employed as t

Antenna systems are provided including a chassi (115) and first and second radiating (110, 120) elements coupled to the chassi. The first radiating element is configured to amplify excitation of the chassi and the second radiating element is configured to reduce excitation of the chassi so as to reduce mutual coupling in the antenna system. Related co- located antennas and methods of controlling m

Susan Petrilli discusses Victoria Welby (1837–1912) and the Signific movement in her book Signifying and Understanding. The disposition of the book is chronological and thematic, and Petrilli’s discussion connects Welby’s work with contemporary semiotics, as well as with the intellectual and scientific landscape of Welby’s own time. For instance, a selection of Welby’s vast correspondence with int

A search for physics beyond the Standard Model in neutral current deep inelastic scattering at high negative four-momentum transfer squared Q(2) is performed in e(+/-)p collisions at HERA. The differential cross section d sigma/dQ(2), measured using the full H1 data sample corresponding to an integrated luminosity of 446 pb(-1), is compared to the Standard Model prediction.
