Impact of advanced inverter functions on low‐voltage power grids

IET Energy Systems Integration, 2021
In today's power grid, a great number of inverter‐based distributed energy resources (DERs) are connected and are mainly designed to supply power without considering the voltage and frequency deviations of the grid.

Advances in recurrence and malignant transformation of sinonasal inverted papillomas

Oncology Letters, 2017
Sinonasal inverted papilloma (SIP) is a benign tumor of the nasal cavity and sinus. SIP is characterized by aggressive malignant transformation and a high rate of recurrence. Inadequate removal of the tumor during surgery is one of the most significant contributors to SIP recurrence. A growing body of evidence suggests that molecular alteration in SIP,

Epigenetic silencing of the liver‐specific lncRNA LUNAR promotes liver cancer progression via NOTCH activation

Molecular Oncology, EarlyView.
LUNAR is a liver‐specific long noncoding RNA (lncRNA) that is highly expressed in normal liver but becomes epigenetically silenced in hepatocellular carcinoma through promoter hypermethylation. Loss of LUNAR is associated with NOTCH activation, epithelial–mesenchymal transition, and metastasis, whereas restoring LUNAR restrains metastatic progression ...

On using the Gameboy Advance as a controller for inverted pendulums [PDF]

2013 International Conference on Robotics, Biomimetics, Intelligent Computational Systems, 2013
This paper describes the usage of a Gameboy Advance (GBA) for non-gaming applications in control systems. The GBA is extended with the XPort and the XPort Robot Controller developed by Charmed Labs. Typical control problems include balancing an inverted pendulum about its unstable vertical equilibrium point. This paper also explores the capabilities of

Hydrostatic pressure activates HIF‐1α via β‐catenin to promote stemness in breast cancer cells

FEBS Open Bio, EarlyView.
To mimic the elevated intestinal fluid pressure in breast cancers, we loaded human breast cancer cells (MCF‐7, MDA‐MB‐453, and BT‐474) to 50 mmHg hydrostatic pressure. Hydrostatic pressure exposure upregulated HIF‐1α and induced stemness in MCF‐7 and BT‐474 cells.
