A genome-wide association study (GWAS) is conducted among a sample of Koreans to identify the gene variants which influence levels of adiponectin, which is associated with obesity and insulin resistance. Results reveal that rs3865188 SNP in CDH13 gene on chromosome 16 is strongly associated with adiponectin, thereby demonstrating that genetic variants in CDH13 influence adiponectin levels in the Korean adults examined.

Reverse embedded-SiGe is a novel n-channel metal oxide semiconductor field-effect transistor (NMOSFET) strained-silicon technique. Findings reveal the effectiveness of the proposed technique in inducing a level of stress comparable to or exceeding conventional strained-silicon techniques.

Polyhedral gold nanocrystals with [O.sub.h] symmetry are synthesized by a modified polyol process in refluxing 1,5-pentanediol (PD). The selective growth conditions are extended to the synthesis of anisotropic nanocrystals, such as rods, wires and branched structures, displaying intriguing optical properties for biomedical applications.

Low-voltage tetracene-based photo thin-film transistors (TFTs) with thin poly-4-vinylphenol (PVP)/Al[O.sub.x] bilayer dielectric was fabricated. It was seen that when two electrodes of Au and semitransparent Ni[O.sub.x] were adopted for source/drain, the tetracene based TFTs with Ni[O.sub.x] exhibited higher field mobility than those with Au due to the band alignment advantage of Ni[O.sub.x] over Au.

Several experiments are conducted to determine the thermoreflectance exhibited by the different metal transducers. The temperature dependence of the optical reflectivity of different metals at different wavelengths is also determined.

A complex x-ray characterization of Ge heterostructures is described, which is integrated on patterned Si(001) substrates by using aspect ratio trapping (ART) and epitaxial lateral overgrowth (ELO). Simulations are used for studying the effect of the different thermal expansion coefficients of Ge, Si and Si[O.sub.2] on the strain status of the ART and ELO Ge heterostructures.

Noncontact thermometry with micron-scale lateral spatial resolution and fast time resolution is enabled by measuring the temperature dependence of two-photon absorption (TPA) on crystalline semiconductors. The studies have shown that in GaP, the contributions to the TPA from the direct transition has shown less temperature dependence than for Si but the additional contribution to the indirect transition has given a similar magnitude as the temperature dependence of TPA on Si.

An analytical approach of operational power defined as load power and rotor loss represented as eddy current loss for applying a permanent magnet (PM) synchronous motor/generator at the high-power flywheel energy storage system is described. The operational power is estimated by backelectromotive force according to the PM rotor speed and the rotor loss is calculated from Poynting theorem.

The time evolution of trapped charge carriers in an oxide layer as in a charge-trap nonvolatile memory is analyzed by using electrostatic force microscopy and Monte Carlo simulation based on Smoluchowski equation for a localized charge system. The measurement of the mean-square displacement (MSD) as a function of time is shown to be consistent with the results obtained from Monte Carlo simulations, thereby disclosing the effect of the Coulomb self-interaction.

A recyclable catalyst is developed for chelation-assisted hydroacylation of an olefin with primary alcohol by using hydrogen-bonding self-assembled catalysts consisting of 2,6-diaminopyridine and barbiturate phosphine-rhodium(I) complex. These two catalysts have acted as homogeneous catalysts after heating due to cleavage of the hydrogen bond and have associated to form supramolecular assemblies via hydrogen bonding that is separated from immiscible product phase upon cooling after the reaction.

A useful catalytic system is found that is especially active for the intra- and intermolecular [4+2] and intra-molecular [5+2] cycloaddition reactions.

An investigation of temporal evolution of particle fluxes in the eastern Brandsfield Strait and the particle fluxes showed large seasonal and interannual variation in particle flux that is closely related to sea ice cover, which limits photoplankton productivity in the surface water.
