Analysis and Design of a Speed and Position System for Maglev Vehicles

Sensors, 2012
This paper mainly researches one method of speed and location detection for maglev vehicles. As the maglev train doesn’t have any physical contact with the rails, it has to use non-contact measuring methods.

Endovascular Treatment of a Ruptured Distal Anterior Cerebral Artery Aneurysm Using Coils and N-Butyl-Cyanoacrylate in a 5-Month-Old Baby

Journal of Clinical Interventional Radiology ISVIR, 2021
Intracranial aneurysms in pediatric population are rare and differ in several features with their adult counterpart. Clipping and endovascular therapy have both demonstrated favorable clinical outcomes with reconstructive and deconstructive techniques ...

α/β coiled coils

eLife, 2016
Coiled coils are the best-understood protein fold, as their backbone structure can uniquely be described by parametric equations. This level of understanding has allowed their manipulation in unprecedented detail. They do not seem a likely source of surprises, yet we describe here the unexpected formation of a new type of fiber by the simple insertion ...

Numerical investigation of turbulent flow heat transfer and pressure drop of AL2O3/water nanofluid in helically coiled tubes [PDF]

, 2013
Passive convective heat transfer enhancement can be achieved by improving the thermo-physical properties of the working fluid, changing flow geometry or both.

Residual tail twisting in ascidian larvae is stabilized by asymmetric myofibrils that resist bilateral symmetry restoration

FEBS Letters, EarlyView.
Ascidian Ciona larvae initially show strong clockwise tail twisting, which is largely corrected during development. However, a small residual twist remains. This study shows that organized helical myofibrils in tail muscles mechanically stabilize this residual asymmetry, preventing complete restoration of bilateral symmetry and revealing how embryos ...

Optimal control laws of onboard coils for the reduction of angular momentum and damping of angular velocity of nanosatellites and microsatellites with magnetic coils on board

Вестник Самарского университета: Аэрокосмическая техника, технологии и машиностроение, 2016
Obtaining a new optimal law of controlling onboard magnetic coils that would provide reduction of the angular momentum of nanosatellites and microsatellites to a predetermined small value and subsequently maintaining it is discussed in the paper.

A new twist to coiled coil

FEBS Letters, 2012
Spectrin repeats have been largely considered as passive linkers or spacers with little functional role other than to convey flexibility to a protein. Whilst this is undoubtedly part of their function, it is by no means all. Whilst the overt structure of all spectrin repeats is a simple triple‐helical coiled coil, the linkages between repeats and the ...

Identification of a Shiga toxin A‐derived peptide internalized into Gb3 receptor‐bearing cells via interaction with the Shiga toxin B subunit

FEBS Letters, EarlyView.
The process of internalization of the Shiga toxin A subunit via formation of a complex with the Shiga toxin B subunit, which specifically binds to the Gb3 receptor. The peptide is designed to act as a carrier of drugs into cancer cells. Here, we explored the potential of peptides derived from the catalytic A subunit of Shiga toxin (STxA) to be drug ...
