Temperature and Bias Dependence of the DC and RF Characteristics of a 150 nm AlGaN/GaN-on-SiC HEMT for Microwave Applications

Mohammad Abdul Alim, Christophe Gaquière

We examine the bias-and temperature-dependent direct current, radio frequency, and equivalent-circuit characteristics of a 150 nm AlGaN/GaN/SiC high-electron-mobility transistor (HEMT) for high-frequency applications. DC and S-parameter measurements on the wafer were conducted under various gate…

Optimizing Gene Selection in DNA Microarray Data Using Multigene Genetic Programming

Chahira Cherif, Mohammed Maiza, Samira Chouraqui, Mustapha Kamel Abdi, Abdelmalik Taleb-Ahmed

Microarray-based cancer classification confronts a fundamental statistical obstacle: the number of measured gene expression features (p) substantially exceeds available tissue samples (n), violating the n > p prerequisite of classical multivariate inference. This dimensionality surplus…
