Impact of the Frequency Support Provided by Grid-Forming DFIG-Based Wind Turbine on Power System Ultra-Low Frequency Oscillation

IEEE Open Access Journal of Power and Energy
Ancillary frequency controls of wind turbines (WTs) bridge the dynamic interplay between turbine mechanics and the electrical grid, enabling WTs to influence low frequency range dynamics in power systems.

NAPRT loss promotes lung tumor initiation and growth through AKT signaling independently of NAD+ biosynthesis

Molecular Oncology, EarlyView.
Loss of NAPRT promotes lung tumor initiation and growth through a noncanonical mechanism, independent of its role in NAD+ biosynthesis. Mechanistically, NAPRT depletion activates the mTORC2‐driven AKT/β‐catenin signaling axis to enhance clonogenic and invasive phenotypes. Furthermore, lung‐specific Naprt deletion significantly increases tumor burden in

Ultra-low-dose CT-images of paranasal sinus.

, 2019
Axial (A) and coronal (B) reformations of 100 kV tin-filtered ultra-low-dose CT of the paranasal sinus of a 63-year-old male (DLP 2.1 mGycm; effective dose 0.012 mSv). Despite the very low dose, the diagnosis of florid sinusitis is easily established. In

Modulation of NTC frequencies by Pc5 ULF pulsations : experimental test of the generation mechanism and magnetoseismology of the emitting surface [PDF]

, 2009
Nonthermal continuum (NTC) radiation is believed to be emitted by the conversion of an electrostatic wave into an electromagnetic one, which takes place at the Earth's magnetic equator.

Time‐restricted feeding prior to Mycobacterium tuberculosis infection reduces tissue CD4+ T cells with limited impact on bacterial clearance

FEBS Open Bio, EarlyView.
Time‐restricted feeding (TRF) in mice increased liver fatty acid oxidation and decreased fatty acid biosynthesis. These alterations persisted when TRF was discontinued and the host was infected with Mycobacterium tuberculosis. Pre‐exposure to TRF did not alter tissue (lung and spleen) mycobacterial burden but significantly reduced CD3+ T cells in lungs

FLC-Based Ultra-Low-Frequency Oscillation Suppression Scheme for Interconnected Power Grids

Energies
The appearance of ultra-low-frequency oscillations in the grid at the sending end, after asynchronous grid interconnection, poses a significant threat to the stable operation of the system. For post-asynchronous interconnection in a multi-DC transmission

Scalp ultra-low frequency electroencephalography

, 2018
Electrical activities of the brain include the regular electroencephalogram (AC-EEG, typically 0.5Hz<f<70 Hz) as well as slow potentials (DC-EEG, f < 0.1Hz). According to recent studies, slow or DC potentials displacements (DC-EEG) are informative features, highly associated with a pathology of diverse neurological disorders.

Aquaporin‐3 and aquaporin‐5 impact the development of pancreatic ductal adenocarcinoma spheroids

FEBS Open Bio, EarlyView.
Schematic representation of the role of aquaporin‐3 (AQP3) and aquaporin‐5 (AQP5) in pancreatic ductal adenocarcinoma (PDAC). Both proteins are upregulated in PDAC and are associated with tumor progression and metastatic potential. Silencing AQP3 or AQP5 in PDAC spheroids results in decreased diameter, area, and overall growth, underscoring their key ...
