A simple design of an ultra-broadband metamaterial absorber (MMA) of terahertz (THz) radiation based on vanadium dioxide (VO) configurations is proposed. The system is composed of a top pattern representing orderly distributed VO strips, a dielectric spacer and an Au reflector. Theoretical analysis based on the electric dipole approximation is performed to characterize the absorption and scattering properties of an individual VO strip.

Data were obtained from the TB and HIV electronic databases. We analysed occurrence of the combined unfavourable outcome (failure, lost to follow-up, death and not evaluated) and death separately, and factors associated with both outcomes using Cox regression.

- Various genetic techniques help trace cell lineage during tissue development, with some focusing on spatial/temporal aspects and others linking gene expression to lineage.
- The G-TRACE system allows for quick visualization of GAL4 expression patterns, enabling genome-wide expression-based lineage studies conducted by UCLA students and high school scholars.
- Findings revealed new expression-based lineage patterns and were compiled into the G-TRACE Expression Database (GED), contributing to better student learning outcomes and retention in STEM fields.
Objective: To report the results of the first 1,132 subjects in a pilot project where local central nervous system trial sites collaborated in the use of a subject database to identify potential duplicate subjects.
Method: Central nervous system sites in Los Angeles and Orange County, California, were contacted by the lead author to seek participation in the project. CTSdatabase, a central nervous system-focused trial subject registry, was utilized to track potential subjects at pre-screen.
