Comparing the paths of Hedgehog release in artificial and natural settings

FEBS Letters, EarlyView.
Hh morphogens require solubilization factors to overcome their tight association with the plasma membrane and signal to distant cells, but the precise functions of these factors are controversial. Here, we use published in vivo observations as the most relevant evidence to test their suggested functions and discuss contradictions and gaps between in ...

Cost based reactive power participation for voltage control in multi units based isolated hybrid power system

Journal of Electrical Systems and Information Technology, 2016
Multi units of wind and diesel based generators in isolated hybrid power system have technical and operational advantages over single units system. They require dynamic reactive power compensation for fast recovery of voltage under load and input changes.

Dose‐dependent hepatotoxicity of hydrogen peroxide in HepG2 cells and its modulation by CYP450 induction

FEBS Open Bio, EarlyView.
NMR metabolomics revealed concentration‐dependent metabolic perturbations in HepG2 cells exposed to H2O2. Rifampicin pretreatment enhanced metabolic competence, attenuated toxin‐induced alterations and produced metabolite profiles more consistent with human liver physiology, supporting the use of CYP450‐induced HepG2 models for improved in vitro ...

REACTIVE POWER COMPENSATION TECHNOLOGIES.

, 2022
Reactive power compensation is the management of reactive power to improve the performance of an network. In general, the problem of reactive power compensation is related to load and voltage support. In addition to the goals, improving the power factor of the system to balance the real power from the mains, strengthening voltage regulation, and ...

Chronobiology of Cancer: How Aging Fuels Oncogenesis at the Molecular Level

Aging and Cancer, EarlyView.
This graphical abstract illustrates the key biological pathways linking aging with cancer development and progression. In the upper left, cumulative exposure to ultraviolet radiation, toxins, and reactive oxygen species (ROS) causes DNA damage and genomic instability, whereas age‐related decline in repair mechanisms, such as ATM/ATR, BER, and NER ...

Experimental Validation of the DSTATCOM Based on SiC-MOSFET Multilevel Converter for Reactive Power Compensation [PDF]

Journal of Systemics, Cybernetics and Informatics, 2020
Power quality problems are associated, among other things, with the reactive power generated at the AC side in distribution systems. In this regard, the three-phase distribution static compensator is becoming a viable alternative in order to achieve ...

Revisiting Stability Criteria in Ball‐Milled High‐Entropy Alloys: Do Hume–Rothery and Thermodynamic Rules Equally Apply?

Advanced Engineering Materials, Volume 27, Issue 6, March 2025.
The stability criteria affecting the formation of high‐entropy alloys, particularly focusing in supersaturated solid solutions produced by mechanical alloying, are analyzed. Criteria based on Hume–Rothery rules are distinguished from those derived from thermodynamic relations. The formers are generally applicable to mechanically alloyed samples.

Fast Transient Hybrid Neuro Fuzzy Controller for STATCOM During Unbalanced Voltage Sags [PDF]

AUT Journal of Electrical Engineering, 2018
A static synchronous compensator (STATCOM) is generally used to regulate voltage and improve transient stability in transmission and distribution networks. This is achieved by controlling reactive power exchange between STATCOM and the grid.
