Rendezvous Simulation for On-Orbit Servicing Missions Using Advanced Robotic Technology [PDF]
, 2013 Increasing complexity and costs of satellite missions promote the idea of extending the operational lifetime or improving functionalities/performance of a satellite in orbit instead of simply replacing it by a new one.

FEBS Letters, EarlyView.Plasma membranes contain dynamic nanoscale domains that organize lipids and receptors. Because viruses operate at similar scales, this architecture shapes early infection steps, including attachment, receptor engagement, and entry. Using influenza A virus and HIV‐1 as examples, we highlight how receptor nanoclusters, multivalent glycan interactions ...

Control of Lagrange point orbits using solar sail propulsion [PDF]
, 2008 Several missions have utilised halo orbits around the L1 and L2 previous termLagrangenext term points of the Earth-Sun system. Due to the instability of these orbits, station-keeping techniques are required to prevent escape after orbit insertion.

FEBS Letters, EarlyView.Embryo‐like structures (stembryos) are an innovative tool, but they are hindered by experimental variability and limited developmental potential. DNA methylation is crucial for mammalian development, but its status in stembryo models is poorly characterized.

FEBS Letters, EarlyView.Septin 9 polybasic domains couple phosphoinositide‐rich membrane binding to centrosome positioning, Golgi organization, and microtubule acetylation to control epithelial polarity. Their loss disrupts this axis, causing centrosome mispositioning, Golgi fragmentation, reduced microtubule acetylation, and polarity inversion via upregulation of the ...

Precise Orbit Determination for the TerraSAR-X Mission [PDF]
, 2006 The TerraSAR-X synthetic aperture radar mission relies exclusively on GPS tracking for a precise post-facto orbit reconstruction. Besides a redundant MosaicGNSS single-frequency receiver, the satellite carries the Integrated GPS Occultation Receiver ...

Degradation mechanism of the von Willebrand factor A2 domain by nattokinase
FEBS Letters, EarlyView.Nattokinase, a natto‐derived protease, exhibits potent antithrombotic effects. This study demonstrates that nattokinase directly cleaves the von Willebrand factor (vWF) A2 domain in vitro. Unlike the native regulator ADAMTS13, nattokinase degrades folded vWF independently of shear stress.

Self-organising low Earth orbit constellations for Earth observation [PDF]
, 2014 This paper presents a novel method of manipulating the spatial pattern of a fractionated micro-satellite constellation in Low Earth Orbit. The method developed allows satellites to manipulate the longitudinal position of their ground-tracks over the ...

Relative Navigation to Non-Cooperative Targets in LEO: Achievable Accuracy from Radar Tracking Measurements [PDF]
, 2013 Any future space debris removal or on-orbit servicing mission faces the problem of the initial relative orbit determination of the servicing satellite to the non-cooperative target.

Modulation of Homer1 EVH1 domain internal dynamics by putative autism‐associated mutations
FEBS Letters, EarlyView.The putative autism‐associated M65I and S97L variants of the EVH1 domain of the postsynaptic scaffold protein Homer1 do not exhibit substantial changes in their overall structure or partner binding. Both of them, but especially the M65I variant, show altered internal dynamics relative to the wild‐type domain on the μs‐ms timescale, indicated by the ...
