High resolution remote sensing missions of a tethered satellite [PDF]
The application of the Tethered Satellite (TS) as an operational remote sensing platform is studied. It represents a new platform capable of covering the altitudes between airplanes and free flying satellites, offering an adequate lifetime, high ...

Cosmic dust collection with a sub satellite tethered to a Space Station [PDF]
The number concentration and density of 1 micron and submicron sized grains in interplanetary space, as well as their relation to the larger zodical dust particles, and the importance of the beta meteoroid phenomenon are currently being questioned.

The Journal of Physiology, EarlyView.Abstract figure legend Beat‐locked mitochondrial ATP transients reveal modular, sex‐specific bioenergetic control during excitation–contraction coupling. A, each action potential activates L‐type CaV1.2 channels, producing a Ca2+ influx that triggers ryanodine receptors (RyR2) and elicits SR Ca2+ release.

Trafficking and potentiation of Nav1.7 and Nav1.8 channels are mediated by IQGAP1
The Journal of Physiology, EarlyView.Abstract figure legend IQGAP1 binds to the voltage‐gated Nav1.7 and Nav1.8 channels and TRPA1 channels in sensory neurons. Inflammatory mediators (IM), including PGE2 and TNFα, released during nerve injury and inflammation activate intracellular signalling messengers such as PKA, p38 MAPK and Cdc42 through their respective receptors.

System engineering study of electrodynamic tether as a spaceborne generator and radiator of electromagnetic waves in the ULF/ELF frequency band [PDF]
The transmission and generation by orbiting tethered satellite systems of information carrying electromagnetic waves in the ULF/ELF frequency band to the Earth at suitably high signal intensities was examined and the system maintaining these intensities ...

Tether length control for orbital transfer of tethered satellite
Tether length control for orbital transfer of tethered satellite本研究では、赤道面内におけるテザー衛星の軌道変換について研究する。非線形制御の手法を用いることにより、指定された軌道上位置でシステムの状態を所望の値にするテザー長の履歴を作成する方法を提案する。テザー長を制御することになるピッチ角運動量の制御、ピッチ角速度の制御、ピッチ角の制御、という3つのステップにより、1つの入力で3つの状態を制御する。提案する手法は、数値反復計算を必要としないだけでなく、テザー張力などの物理的拘束にも対応できる。また、システムの状態を正確に目標値に一致させることができる。 This study discusses orbital transfer of a tethered satellite system in equatorial plane.

Technologies for engineering repetitive DNA
Quantitative Biology, Volume 14, Issue 3, September 2026.Abstract Repetitive DNA, a fundamental architectural element of genomes, is widespread across organisms and comprises about 54% of the human genome. With advances in long‐read sequencing and bioinformatics approaches, highly repetitive sequences can now be characterized in depth.

Feasibility of hydromagnetic wave measurements on space shuttle [PDF]
The feasibility of using a hydromagnetic wave sensor on the space shuttles was investigated. It was found that although existing sensors are inadequate in terms of resolution, dynamic range, and frequency range, they can be modified to make the necessary
