One of the two yin-yang mirrors arrives at LLNL. The plasma was confined in the small area between the two magnets. Drawing of the MFTF building. The Mirror Fusion Test Facility, or MFTF, was an experimental magnetic confinement fusion device built using the tandem magnetic mirror design. It was, by far, the largest, most powerful and most ...
Narcolepsy is a chronic neurological disorder that impairs the ability to regulate sleep–wake cycles, and specifically impacts REM (rapid eye movement) sleep. [1] The pentad symptoms of narcolepsy include excessive daytime sleepiness (EDS), sleep-related hallucinations, sleep paralysis, disturbed nocturnal sleep (DNS), and cataplexy. [1]
Nikon (under the Mirror-Nikkor and later Reflex-Nikkor names) and Canon both offered several designs, such as 500 mm 1:8 and 1000 mm 1:11. Smaller companies such as Tamron , Samyang , Vivitar , and Opteka also offered several versions, with the three latter of these brands still actively producing a number of catadioptric lenses for use in ...
Ramachandran created the mirror box to relieve pain by helping an amputee imagine motor control over a missing limb. Mirror therapy is now also widely used for treatment of motor disorders such as hemiplegia or cerebral palsy. As Deconick et al. state in a 2014 review, the mechanism of improved motor control and pain relief may differ from the ...
The full mechanism of action of sodium oxybate is poorly understood. [ 3 ] [ 7 ] GHB is a normal metabolite of GABA that interacts with the GABA B receptor and the GHB receptor . [ 3 ] It has been shown to enhance the restorativeness of sleep in part by altering sleep architecture in narcoleptic patients.
An additional benefit is that micromachining technologies allow for the benefit of economies of scale to create cheaper and lighter deformable mirrors with a greater number of actuators. [6] Membrane concept mirrors are formed by a thin conductive and reflective membrane stretched over a solid flat frame. The membrane can be deformed ...
A magnetic mirror, also known as a magnetic trap or sometimes as a pyrotron, is a type of magnetic confinement fusion device used in fusion power to trap high temperature plasma using magnetic fields. The mirror was one of the earliest major approaches to fusion power, along with the stellarator and z-pinch machines.
The so-called mirror box was a simple apparatus that uses a mirror reflecting an amputee's good arm so it appears to be the extension of the one missing: They put their surviving arm through a hole in the side of a box with a mirror inside, so that, peering through the open top, they would see their arm and its mirror image, as if they had two ...
