Thermal Boundary Resistance Extraction of GaN-on-Diamond Substrate from Transmission Line Method Pattern Using Micro-Raman Spectroscopy and Thermal Simulation.

Heat dissipation properties are very important in AlGaN/GaN RF devices operating at high frequency and high power. Therefore, in order to extract the thermal conductivity of the substrate and device, which are essential for the analysis of the heat dissipation characteristics, various methods of extraction were attempted. And this experiments were conducted in parallel with micro-raman measurement and thermal simulation.

Effects of Recessed-Gate Structure on AlGaN/GaN-on-SiC MIS-HEMTs with Thin AlON MIS Gate.

This study investigated the effects of a thin aluminum oxynitride (AlON) gate insulator on the electrical characteristics of AlGaN/GaN-on-SiC metal-insulator-semiconductor high electron mobility transistors (MIS-HEMTs). The fabricated AlGaN/GaN-on-SiC MIS-HEMTs exhibited a significant reduction in gate leakage and off-state drain currents in comparison with the conventional Schottky-gate HEMTs, thus enhancing the breakdown voltage. The effects of gate recess were also investigated while using recessed MIS-HEMT configuration.

Comparison of biosimilar filgrastim with a reference product: pharmacokinetics, pharmacodynamics, and safety profiles in healthy volunteers.

Purpose: Filgrastim, a granulocyte-colony stimulating factor, is used to treat patients with neutropenia, including neutropenic fever. Leucostim is a recombinant filgrastim product tested for biosimilarity with its reference product, Neupogen. We conducted a comparative clinical trial of the 2 products.

Evaluation of process efficiency and bioequivalence of biosimilar recombinant human chorionic gonadotropin (rhCG).

Background: Human chorionic gonadotropin (hCG) is a therapeutic protein used for ovulation induction in women with infertility. Dong-A Pharm. Co.

Elevated serum gamma-glutamyltransferase levels are independently associated with insulin resistance in non-diabetic subjects.

We investigated the associations of gamma-glutamyltransferase (GGT) with visceral obesity, adiponectin and retinol binding protein 4 (RBP4), and insulin resistance (IR) and compared these associations with other liver enzymes in non-diabetes. We enrolled 94 healthy subjects 30-69 years old. Clinical and biochemical metabolic parameters were measured.
