Modified A-Source Converter Operating at Lower Voltage Stress

IEEE Access, 2019
The coupled inductor based Z-source converter produces higher voltage gain with lower number of components count. In this paper, a new two winding mutually coupled inductor based Z-source DC-DC converter is proposed to boost the voltage gain.

Design of an LCC current-output resonant converter for use as a constant current source [PDF]

, 2007
A methodology for the design of LCC resonant current-source converters, is presented. Unlike previous techniques, the resulting converter provides near constant steady-state output current over an extended load range when excited at the resonant ...

TRAIL‐PEG‐Apt‐PLGA nanosystem as an aptamer‐targeted drug delivery system potential for triple‐negative breast cancer therapy using in vivo mouse model

Molecular Oncology, EarlyView.
Aptamers are used both therapeutically and as targeting agents in cancer treatment. We developed an aptamer‐targeted PLGA–TRAIL nanosystem that exhibited superior therapeutic efficacy in NOD/SCID breast cancer models. This nanosystem represents a novel biotechnological drug candidate for suppressing resistance development in breast cancer.

On-Chip Matching Networks for Radio-Frequency Single-Electron-Transistors

, 2007
In this letter, we describe operation of a radio-frequency superconducting single electron transistor (RF-SSET) with an on-chip superconducting LC matching network consisting of a spiral inductor L and its capacitance to ground.

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment

Molecular Oncology, EarlyView.
This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

Generalized Parity-Time Symmetry Condition for Enhanced Sensor Telemetry

, 2018
Wireless sensors based on micro-machined tunable resonators are important in a variety of applications, ranging from medical diagnosis to industrial and environmental monitoring.The sensitivity of these devices is, however, often limited by their low ...

A Robust 43-GHz VCO in CMOS for OC-768 SONET Applications [PDF]

, 2004
In this paper, we present a 43-GHz LC-VCO in 0.13-/spl mu/m CMOS for use in SONET OC-768 optical networks. A tuned output buffer is used to provide 1.3 V/sub p-p/ (single-ended) into a 90-fF capacitive load as is required when the VCO is used in typical ...

Colorectal cancer‐derived FGF19 is a metabolically active serum biomarker that exerts enteroendocrine effects on mouse liver

Molecular Oncology, EarlyView.
Meta‐transcriptome analysis identified FGF19 as a peptide enteroendocrine hormone associated with colorectal cancer prognosis. In vivo xenograft models showed release of FGF19 into the blood at levels that correlated with tumor volumes. Tumoral‐FGF19 altered murine liver metabolism through FGFR4, thereby reducing bile acid synthesis and increasing ...

Coupled Inductor-Based ZVS Interleaved Buck Converter with Optimal Coupling Coefficient and Fully Digital BCM Control

Mathematics
In this paper, a coupled-inductor-based interleaved Buck converter is presented. By employing a negatively coupled inductor, the proposed topology reduces magnetic component number and improves dynamic response. Operating in boundary conduction mode (BCM)
