Formulating the Net Gain of MISO-SFN in the Presence of Self-Interferences [PDF]
Radioengineering, 2015 In this study, an analytical formula for multiple-input single-output single frequency network gain (MISO-SFNG) is investigated. To formulate the net MISO-SFNG, we derived the average signal to interference plus noise ratio (SINR) where the gain achieved

Janus Magnetic Polymeric Colloids Gradient Thin Films of Amino Dextran Coated Core-Shell Poly (Styrene/Divinylbenzene/Methacrylic Acid) for Ultrasensitive Magnetic Resonance Imaging. [PDF]
Int J BiomaterThe present study focuses on developing novel gradient thin films for surface‐based magnetic resonance imaging of fluids such as water. Four types of magnetic‐polymer colloids were investigated as T2 contrast agents, including Janus magnetic‐polystyrene and core–shell magnetic‐poly(styrene/divinylbenzene/methacrylic acid) particles. These colloids were
