Appraisal of digital terrain elevation data for low-altitude flight [PDF]

open access: yes
The use of terrain elevation databases in advanced guidance and navigation systems has greatly expanded. However, the limitations and accuracies of these databases must be considered and established prior to safe system flight evaluation.

Structural biology of ferritin nanocages

open access: yesFEBS Letters, EarlyView.
Ferritin is a conserved iron‐storage protein that sequesters iron as a ferric mineral core within a nanocage, protecting cells from oxidative damage and maintaining iron homeostasis. This review discusses ferritin biology, structure, and function, and highlights recent cryo‐EM studies revealing mechanisms of ferritinophagy, cellular iron uptake, and ...

Design and Performance Analysis of the WDM Schemes for Radio over Fiber System With Different Fiber Propagation Losses

open access: yesFibers, 2019
The integration of optical and wireless networks increases mobility and capacity and decreases costs in access networks. Fibre optic communication can be considered optical communication that combines the methodologies of two communications, and it may ...

Performance Analysis of Energy-Detection-Based Massive SIMO

open access: yes, 2015
Recently, communications systems that are both energy efficient and reliable are under investigation. In this paper, we concentrate on an energy-detection-based transmission scheme where a communication scenario between a transmitter with one antenna and

Organ‐specific redox imbalances in spinal muscular atrophy mice are partially rescued by SMN antisense oligonucleotides

open access: yesFEBS Letters, EarlyView.
We identified a systemic, progressive loss of protein S‐glutathionylation—detected by nonreducing western blotting—alongside dysregulation of glutathione‐cycle enzymes in both neuronal and peripheral tissues of Taiwanese SMA mice. These alterations were partially rescued by SMN antisense oligonucleotide therapy, revealing persistent redox imbalance as ...

Central Receiver-Based CSP Plants: Trends and Categorization

open access: yesSolarPACES Conference Proceedings
Central receiver-based concentrated solar power (CSP) systems play a crucial role in solar energy technology, particularly for their ability to operate at higher temperatures than conventional linear concentrators, and for better integration of thermal ...

Phase Retrieval in Short-Range Optical Communication Using Temporal Transport-of-Intensity Equation with Direct Detection

open access: yesPhotonics
Direct detection (DD) is a straightforward, cost-effective receiving scheme for medium- and short-range fiber-optic communication systems, yet directly accessing phase information presents inherent challenges. The temporal transport-of-intensity equation

SoFiA – A Novel Simulation Tool for Central Receiver Systems

open access: yesEnergy Procedia, 2014
AbstractA new simulation environment named SoFiA for the Solar Field Assessment for Central Receiver Systems (CRS) has been developed. CRS technology entails a higher degree of complexity in analysis and design relative to other CSP technologies. SoFiA approaches these difficulties in a staged way with different quality levels.

Transferrin receptor 1‐mediated iron uptake supports thermogenic activation in human cervical‐derived adipocytes

open access: yesFEBS Letters, EarlyView.
In this study, we found that human cervical‐derived adipocytes maintain intracellular iron level by regulating the expression of iron transport‐related proteins during adrenergic stimulation. Melanotransferrin is predicted to interact with transferrin receptor 1 based on in silico analysis.
