    • Systems and methods for attenuating light from undesired sources in a coronagraph apparatus are provided. The coronagraph includes a first imaging lens that receives light representing a desired image and an undesired central image and a reimaging system that mitigates the undesired central image. The reimaging system includes a composite half-wave plate assembly that includes a plurality of angular half-wave plate sections. Each of the plurality of angular half-wave plate sections have two congruent sides that meet at an apex substantially at a center of the composite half-wave plate. A characteristic c-axis associated with a given angular half-wave plate section is aligned differently from the respective characteristic c-axes of at least two angular half-wave plate sections in substantial contact with the two sides of the given angular half-wave plate section. A fixation element engages the half-wave plate sections to maintain the angular half-wave plate sections in a desired arrangement.

    • A free-electron laser system and optical polarization conversion are provided for producing azimuthal polarization and radial polarization laser beams. The free-electron laser system includes a helical wiggler for generating a transverse magnetic field around a beam axis. An electron beam is projected along the beam axis and interacts with the transverse magnetic field so as to induce spontaneous and stimulated emission of optical radiation. A resonator cavity is formed by a pair of mirrors in which the optical radiation oscillates therein. The laser system directly produces an azimuthal polarization laser beam as an output. The laser system may further be coupled to an optical polarization converter which includes a pair of optical half-wave plates having a forty-five degree (45.degree.) optical axis difference therebetween. The azimuthal polarization laser beam is transmitted through the optical polarization converter so as to generate a radial polarization output beam. The optical polarization converter may further operate as a bi-directional optical polarization converter for converting between azimuthal polarization and radial polarization laser beams. In addition, optical polarization converter may further operate with other optical axis differences so as to provide a general polarization rotator for rotating polarization according to directions based on selected arbitrary angles.

    • The present invention provides a method of treating or preventing hyperlipidemia in a subject in need thereof. Such method includes, specifically, administrating to the subject a therapeutically effective amount of a caffeamide derivative. The present invention also provides a pharmaceutical composition containing, primarily, the caffeamide derivative. The method and pharmaceutical composition of the present invention can effectively and significantly lower the high-fat diet-induced body weight gain and absolute visceral fat weight as well as the concentration of triglycerides and free fatty acids in blood, and levels of total lipid and triacylglycerol in liver tissue. In addition, the caffeamide of the present invention also reduces size of adipocyte, hepatocellular ballooning phenomenon, and liver steatosis. Through promotion of phosphorylation of 5′ adenosine monophosphate-activated protein kinase (AMPK) in muscle and liver, the caffeamide derivatives of the present invention is suitable for ameliorating or remedying hyperlipidemia.
