USAGE OF 5G IN UAV MISSIONS FOR ISR
Traditionally, UAVs operate on a one-to-one transmission mode where the UAVs have one data link between one ground command and control station. Therefore, the radius at which the UAV can travel is limited. The bandwidth of the traditional link is limited to less than 8Mbps and the quality of the …

Study of waves observed in the equatorial ionospheric valley region using Jicamarca ISR and VIPIR ionosonde
… of the physics of this region, we used JRO ISR and VIPIR ionosonde techniques to perform high spatial and temporal resolution measurements. We found correlations between VHF backscatter radar measurements and fluctuations detected with the VIPIR ionosonde, which is an indication of gravity …

Investigating coordination between stress-induced translational and transcriptional attenuation
… including the integrated stress response (ISR) and stress-induced transcriptional downregulation (SITA). SITA and the ISR inhibit global transcription and translation respectively, while stress-induced transcripts escape both pathways and are upregulated. The ISR is physiologically relevant …

Plasma line generation and spectral estimation from Arecibo Observatory radar data
Incoherent scatter radar (ISR) signal spectrum is a statistical measure of Bragg scattered radio waves from thermal fluctuations of the electron density in the ionosphere. The ISR spectrum consists of up- and down-shifted electron plasma lines and a double-humped ion-line component associated with …

Evolutionary conservation and characterization of the metazoan amino acid response
… part of the larger Integrated Stress Response (ISR) in mammals. The ISR consists of multiple branches, each one triggered by distinct stresses that produce phospho-eIF2α signal generation. Each ISR initiating stress results in a unique cellular response due to activation of both the ISR and …

New Roles for the Integrated Stress Response in Cancer and Proteostasis
<p>The integrated stress response (ISR) is a highly conserved pathway that senses diverse stresses and responds by limiting total protein synthesis and redirecting translation to stress response transcripts. The ISR has the potential to modify a broad range of processes in cancer, but the major …

Full-profile inversion of ionospheric radar data from Arecibo observatory
Incoherent scatter radar (ISR) technique is used to probe the ionosphere and measure the key state parameters of the ionosphere in thermodynamic equilibrium, including its electron density, ion densities and compositions, electron and ion temperatures, and the associated drift velocities of …

The Physiology and Pharmacology of FGF21 in the Exocrine Pancreas
… such as the integrated stress response pathway (ISR). Genetic, chemical or traumatic events can trigger an inflammatory response in the pancreas known as pancreatitis with prolonged ISR activation. In the pancreas, fibroblast growth factor 21 (FGF21) is highly expressed, induced by feeding and …

GCN2 eIF2 Kinase Promotes Prostate Cancer by Maintaining Amino Acid Homeostasis
Activation of the integrated stress response (ISR) contributes to the progression of many cancers, including prostate cancer (PCa). The ISR features a family of protein kinases that phosphorylate the eukaryotic translation initiation factor 2 (eIF2) during different stress conditions, repressing …

A MOLECULE-INHIBITOR OF THE INTEGRATED STRESS RESPONSE REGULATES ACTIVITY OF MAMMALIAN EUKARYOTIC TRANSLATION INITIATION FACTOR 2B
The Integrated Stress Response (ISR) is a conserved eukaryotic translational and transcriptional program implicated in mammalian metabolism, memory and immunity. Although mainly considered to be a protective mechanism, prolonged and severe ISR can result in cell death. The ISR is activated by …

Inversion of Arecibo incoherent scatter radar coded long pulse backscatter spectra
Incoherent scatter radar (ISR) at Arecibo Observatory measures the scattering of electromagnetic waves from random density fluctuations of ionospheric plasma particles (electrons and ions). Information about particle temperatures, ion concentrations, and Doppler shifts caused by particle motions …
