Melba Fiser collection, 1990-1992
No full textThis collection contains correspondence, handwritten daily notes, signed petitions, reports, contact lists, printed material, and photographs. The material was collected by Melba Fiser, a state coordinator for the Anti-Striker Replacement letter campaign in Arkansas concerning the group's efforts to gather support for the Strike Participation bill. Included are letters and printed material concerning worker and union member issues in Arkansas as well as items from the 1992 presidential campaign.; Photographs in the collection depict Fiser at various campaigns in Arkansas and nationwide, including rallies for the American Federation of Labor-Congress of Industrial Organizations (AFL-CIO), containing images of Fiser, labor leader J. Bill Becker, and politician and civil rights leader Rev. Jesse Jackson.Melba Fiser collection, 1990-199
Theoretical study of the CS2+ dication
No full textThe potential energy and spin-orbit coupling functions of 11 lowest electronic states of CS2+ dication have been calculated using internally contracted multireference configuration method. Using these functions, the positions and widths of the corresponding vibronic levels have been evaluated by means of the stabilization and log-phase-amplitude methods. The states governing the second step in the sequential pathway CS23+-> S++CS2+-> S++C++S+ of the overall three-body Coulomb explosion of CS23+ have been determined
Computed lifetimes of metastable states of CO2+
No full textHighly correlated internally contracted multireference configuration interaction wave functions are used to calculate the potential energy and spin-orbit coupling functions for the lowest electronic states of CO2+ dication. Using these functions, the positions and lifetimes of the corresponding vibronic states are evaluated by means of log-phase-amplitude, stabilization, and complex-scaling methods within the framework of a multichannel Schrodinger analysis. For the first time in the literature, the calculated lifetimes are in good agreement with the experiment, thereby proving the reliability of the predicted characteristics and adequacy of the used theory for a theoretical study of other molecular dications
Chronomics: the broad scope of monitoring chronomes : a review
No full textThe aim of the present paper is to summarized the data on biological rhythms in living organisms including man and summarise data on circadian, circaseptan and other rhythms in geophysical variables. The synchronisation of both geophysical and biological activities and their oscillations are discussed
Computed lifetimes of metastable states of the NO++ dication
No full textBased on the ab initio potential energy, spin-orbit coupling, electronic transition dipole moment, and radial nonadiabatic coupling functions, the energy level positions, lifetimes, and radiative transition probabilities (Einstein A coefficients) have been determined for the lowest electronic states of NO2+ using the log-amplitude-phase, stabilization, and complex-scaling methods. The calculated characteristics are in reasonable agreement to the available experimental data, thus, evidencing the reliability of the theoretical predictions for the characteristics unobserved to date. With the exception of the v2 vibrational states of the B 2+ electronic state, the calculated radiative lifetimes of the excited electronic states are longer than their predissociation lifetimes, hence, accounting for the failure of the attempts which have been made so far to observe any emission from the latter states

Atomic scale interfacial magnetism and origin of metal-insulator transition in (LaNiO 3 ) n /(CaMnO 3 ) m superlattices: a first principles study
No full textAbstract Interfacial magnetism and metal-insulator transition at LaNiO 3 -based oxide interfaces have triggered intense research efforts, because of the possible implications in future heterostructure device design and engineering. Experimental observation lack in some points a support from an atomistic view. In an effort to fill such gap, we hereby investigate the structural, electronic, and magnetic properties of (LaNiO 3 ) n /(CaMnO 3 ) m superlattices with varying LaNiO 3 thickness (n) using density functional theory including a Hubbard-type effective on-site Coulomb term. We successfully capture and explain the metal-insulator transition and interfacial magnetic properties, such as magnetic alignments and induced Ni magnetic moments which were recently observed experimentally in nickelate-based heterostructures. In the superlattices modeled in our study, an insulating state is found for n=1 and a metallic character for n=2, 4, with major contribution from Ni and Mn 3d states. The insulating character originates from the disorder effect induced by sudden environment change for the octahedra at the interface, and associated to localized electronic states; on the other hand, for larger n, less localized interfacial states and increased polarity of the LaNiO 3 layers contribute to metallicity. We discuss how the interplay between double and super-exchange interaction via complex structural and charge redistributions results in interfacial magnetism. While (LaNiO 3 ) n /(CaMnO 3 ) m superlattices are chosen as prototype and for their experimental feasibility, our approach is generally applicable to understand the intricate roles of interfacial states and exchange mechanism between magnetic ions towards the overall response of a magnetic interface or superlattice

Nonlinear acoustic waves in the viscous thermosphere and ionosphere above earthquake
No full textThe nonlinear behavior of acoustic waves and their dissipation in the upper atmosphere is studied on the example of infrasound waves generated by vertical motion of the ground surface during the Mw 8.3 earthquake that occurred about 46 km from Illapel, Chile on 16 September 2015. To conserve energy, the amplitude of infrasound waves initially increased as the waves propagated upward to the rarefied air. When the velocities of air particles became comparable with the local sound speed, the nonlinear effects started to play an important role. Consequently, the shape of waveform changed significantly with increasing height, and the original wave packet transformed to the “N-shaped” pulse resembling a shock wave. A unique observation by the continuous Doppler sounder at the altitude of about 195 km is in good agreement with full wave numerical simulation that uses as boundary condition the measured vertical motion of the ground surface.Fil: Chum, J..
