The Next Higher Spin Currents and Three-Point Functions in the Large Holography
By using the known operator product expansions (OPEs) between the lowest
higher spin currents of spins in an extension of the large linear superconformal algebra,
one determines the OPEs between the lowest higher spin currents in an
extension of the large nonlinear superconformal algebra for
generic and . The Wolf space coset contains the group and
the affine Kac-Moody spin current has the level . The next higher
spin currents of spins arise in
the above OPEs. The most general lowest higher spin current in this
multiplet can be determined in terms of affine Kac-Moody spin
currents. By careful analysis of the zero mode (higher spin) eigenvalue
equations, the three-point functions of bosonic higher spin currents
with two scalars are obtained for finite and . Furthermore, we also
analyze the three-point functions of bosonic higher spin currents in
the extension of the large linear superconformal algebra. It turns
out that the three-point functions of higher spin currents in the two
cases are equal to each other at finite and . Under the large 't
Hooft limit, the two descriptions for the three-point functions of higher spin
current coincide with each other. The higher spin extension of
Knizhnik Bershadsky algebra is described.Comment: 94 pages; The 43 and 44 pages added, the mathematica notebook files

Organizing Pneumonia by Paragonimiasis and Coexistent Aspergilloma Manifested as a Pulmonary Irregular Nodule
Organizing pneumonia by paragonimiasis and coexistent aspergilloma as a pulmonary nodule is a rare case of lung disease. Its radiographic or CT feature has not been described before in the radiologic literature. We present organizing pneumonia by paragonimiasis and coexistent aspergilloma manifested as a pulmonary irregular nodule on CT
GaAs droplet quantum dots with nanometer-thin capping layer for plasmonic applications
We report on the growth and optical characterisation of droplet GaAs quantum
dots with extremely-thin (11 nm) capping layers. To achieve such result, an
internal thermal heating step is introduced during the growth and its role in
the morphological properties of the quantum dots obtained is investigated via
scanning electron and atomic force microscopy. Photoluminescence measurements
at cryogenic temperatures show optically stable, sharp and bright emission from
single quantum dots, at near-infrared wavelengths. Given the quality of their
optical properties and the proximity to the surface, such emitters are ideal
candidates for the investigation of near field effects, like the coupling to
plasmonic modes, in order to strongly control the directionality of the
emission and/or the spontaneous emission rate, crucial parameters for quantum
photonic applications.Comment: 1 pages, 3 figure
