An Implementation of a Dynamic Voltage Restorer

, 2004
The design and implementation of a dynamic voltage restorer (DVR) is presented in this thesis. The proposed DVR can restore the end-user voltage to its normal level by rapidly injecting a compensating voltage onto the power line against the upstream ...

Enhanced control of DFIG using fuzzy backstepping under asymmetrical voltage dips with dynamic voltage restorer

Engineering Science and Technology, an International Journal
This paper presents a coordinated control strategy for a doubly fed induction generator (DFIG) under asymmetrical voltage dips, combining a Dynamic Voltage Restorer based on hysteresis voltage control (DVR–HVC) with a fuzzy backstepping controller (FBSC)

Preoperative circulating tumor cells integrated with imaging analysis for prognostic evaluation in head and neck squamous cell carcinoma

Molecular Oncology, EarlyView.
Detecting circulating tumor cells (CTCs) in blood before surgery may help predict outcomes in patients with head and neck squamous cell carcinoma (HNSCC). Here, we show when combined with tumor size and lymph node involvement from routine imaging, CTC status identifies high‐risk patients with poorer survival—offering a simple, minimally invasive tool ...

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 ...

Simultaneous communication and processor voltage scaling for dynamic and leakage energy reduction in time-constrained systems

, 2004
We propose a new technique for the combined voltage scaling of processors and communication links, taking into account dynamic as well as leakage power consumption.

Dynamic voltage restoration with minimum energy injection

, 2000
Voltage sag is one of the most important power quality problems challenging the utility industry. Voltage sags can be compensated for by voltage and power injection into the distribution system.

CEACAM1 participation in breast cancer progression

Molecular Oncology, EarlyView.
In invasive breast cancer (BC), CEACAM1 shifts from an apical to a uniform membranous/cytoplasmic pattern, or is lost, as tumors dedifferentiate, inversely tracking the Ki‐67 proliferative index. In MCF‐7 cells, only CEACAM1‐4L suppresses proliferation, repressing cell cycle and growth factor genes.
