ABSTRACT Understanding the ways in which pathogens invade and neutralize their hosts is of great interest from both an academic and a clinical perspective. However, in many cases genetic tools are unavailable or insufficient to fully characterize the detailed mechanisms of pathogenesis. Small molecule approaches are particularly powerful due to their ability to modulate specific biological functions in a highly controlled manner and their potential to broadly target conserved processes across species. Recently, two approaches that make use of small molecules, activity-based protein profiling and high-throughput phenotypic screening, have begun to find applications in the study of pathways involved in pathogenesis. In this Review we highlight ways in which these techniques have been applied to examine bacterial and parasitic pathogenesis and discuss possible ways in which these efforts can be expanded in the near future.

    ABSTRACT: Summary form only given. Lasing action has been demonstrated in a vacuum-deposited 3000 Å thick layer of tris-(8-hydroxyquinoline)aluminum (Alq<sub>3</sub>) doped with DCM laser dye. We observed a remarkably low lasing threshold at a pump energy density of 1 μJ/cm<sup>2</sup> with a 500 psec excitation pulse. Initial lifetime measurements showed an extremely high photochemical stability of the laser material. The low lasing threshold and high stability are primarily due to an excitation method in which pump light is absorbed by the host material (Alq<sub>3</sub>), and the light emitting DCM molecules are excited by means of an efficient non-radiative energy transfer from the Alq<sub>3</sub> molecules. We also found that the facets of vacuum-deposited films are optically smooth, providing enough reflection for feedback. Hence, no processing of the material is necessary to fabricate a good optical cavity

    ABSTRACT: In this paper, a new modeling methodology for thin film bulk acoustic resonators (TFBAR) is presented and the formulations for each lumped element in the model are also presented. The proposed model has three optimization variables which is half of the modified Butterworth-Van Dyke (MBVD) model, and as a result the curve fitting for the measured data is much faster and more accurate than any other conventional models. In addition, two types TFBAR ladder filters are designed and fabricated to analyze the effects of on-wafer inductor integration. Fabricated on-wafer spiral inductor reveals the Q-factor of 9 at 2 GHz and the inductor integrated filters have approximately 10 to 12 dB out-of-band rejection improvement compared to the original filters.
