Radio-frequency (RF) performance of multi-finger partially depleted silicon-on-insulator (SoI) nMOSFETs with tunnel diode body contact (TDBC) structure is investigated in this letter. The TDBC structure suppresses floating-body effect and body instability significantly and shows less drain conductance degradation with respect to FB and TB devices. The peak cutoff frequency (f T ) and maximum oscillation frequency (f MAX ) of TDBC devices are 96.4 and 132.8 GHz, respectively. Due to lower parasitic resistances and capacitances, the device with TDBC structures represents an improvement of 10% for the f T and of 90% for the f MAX compared with conventional T-gate body-contact devices. The investigation results indicate that TDBC SoI MOSFETs are a good candidate for analog and RF applications.Index Terms-Radio-frequency (RF), tunnel diode, body contact, floating body, partially depleted silicon-on-insulator.

Hepatic transporters facilitate the uptake of xenobiotic compounds and confer immense potential as multimodality reporters, as they can uptake multitude of bioluminescent, fluorescence, near Infra-red (NIR), and magnetic resonance imaging (MRI) compounds. Here, it is aimed to identify the prospects of three human hepatocyte membrane proteins, organic anion transporters (OATP) 1B1, OATP1B3, and sodium-taurocholate cotransporting polypeptide in tracing the transplanted cells dynamics, by the uptake of clinically approved MRI compound, gadolinium ethoxybenzyl-diethylenetriaminepentaacetic acid (GD-EOB DTPA) or NIR fluorescent dye, Indocyanine Green (ICG). First, OATP1B1 is introduced as new MRI reporter which is the human orthologue of previously established rodent (Oatp1a1) reporter. Comparative sequential assays by assimilating MR image parameters reveal OATP1B3 as superior reporter on T1-weighted images and display highest contrast enhancement reported to-date when using a clinical 3T MR scanner (≈21-fold in vitro; ≈8-fold in vivo). Stably expressing these hepatic transporters have no effect on human adipose derived mesenchymal stem cells (hADSCs) characteristics. However, only OATP1B3 able to trace as few as 2 × 10 5 hADSCs intramuscular xenograft survival time on NIR and 3T MRI. These data suggest that OATP1B3 is relatively a robust Gd-EOB-DTPA/ICG-dependent multimodality reporter in visualizing dynamic processes for cell-based therapies.
