Novel Scalable Topologies of High Power Density Quadratic Converters With Low Voltage Stress on Power Diode

IEEE Open Journal of the Industrial Electronics Society
High-gain dc–dc converters are used for a number of applications including the power processing of several low-voltage renewable energy sources (solar photovoltaic and fuel cells) while they are integrated into a microgrid. This article introduces

Hybrid and Three-Level Three-Phase Rectifiers Using Interleaved DCM Boost Converters

IEEE Access, 2019
Two new three-phase high-power-factor rectifiers using an interleaved discontinuous conduction mode (DCM) boost converters in a three-level configuration are proposed in this paper. The input currents waveforms follow the input voltages waveforms without

Effect of negative bias temperature instability induced by a low stress voltage on nanoscale high-k/metal gate pMOSFETs

, 2018
The effect of a low stress voltage on the negative bias temperature instability degradation in a nanoscale p-channel metal-oxide-semiconductor field-effect transistor using high-k/metal gate stacks is investigated.

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.

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 ...

Self-Balanced Hexagon-Type Multilevel Inverter With Low Total Standing Voltage and High Efficiency

IEEE Open Journal of Power Electronics
This paper presents a seven-level switched-capacitor bipolar multilevel inverter topology that offers a minimum number of whole components. The proposed topology generates an output waveform with a single DC source, three capacitors with a rating equal ...

Circular RNA expression landscapes in myelodysplastic neoplasms: Associations with mutational signatures and disease progression

Molecular Oncology, EarlyView.
In this explorative study, the abundance of circular RNA molecules in bone marrow stem cells was found to be elevated in patients with high‐risk myelodysplastic neoplasms, and to be associated with an increased risk of progression to acute myeloid leukemia.

Subtype‐specific enhancer RNAs define transcriptional regulators and prognosis in breast cancers

Molecular Oncology, EarlyView.
This study employed machine learning methodologies to perform the subtype‐specific classification of RNA‐seq data sets, which are mapped on enhancers from TCGA‐derived breast cancer patients. Their integration with gene expression (referred to as ProxCReAM eRNAs) and chromatin accessibility profiles has the potential to identify lineage‐specific and ...
