Pellucid marginal degeneration (PMD) is a degenerative corneal condition, often confused with keratoconus. It typically presents with painless vision loss affecting both eyes. It typically presents with painless vision loss affecting both eyes.
Pelizaeus–Merzbacher disease is an X-linked neurological disorder that damages oligodendrocytes in the central nervous system.It is caused by mutations in proteolipid protein 1 (PLP1), a major myelin protein.
A PMD typically consists of two main layers Veto Detector and Preshower Detector. Veto Detector layer is designed to reject charged particles. Photons pass through a converter in Preshower Detector layer, initiating an electromagnetic shower. The detector then measures the number of cells activated by the shower, providing information about the ...
Photomultiplier. Photomultiplier tubes (photomultipliers or PMTs for short) are extremely sensitive detectors of light in the ultraviolet, visible, and near-infrared ranges of the electromagnetic spectrum.
Hitomi (Japanese: ひとみ), also known as ASTRO-H and New X-ray Telescope (NeXT), was an X-ray astronomy satellite commissioned by the Japan Aerospace Exploration Agency for studying extremely energetic processes in the Universe.
On this episode of Take My Money, PureWow creator Kate Kesselman tests the viral PMD Clean Smart Facial Cleansing Device ($172; $229), which uses LED blue light, to see if it really helps clear up ...
Polarization mode dispersion (PMD) is a form of modal dispersion where two different polarizations of light in a waveguide, which normally travel at the same speed, travel at different speeds due to random imperfections and asymmetries, causing random spreading of optical pulses. Unless it is compensated, which is difficult, this ultimately ...
Potentially. The PMD Wave Pro uses electrical muscle stimulation (EMS) to give the skin a more toned and lifted appearance. As reported by CNN, the use of EMS has a history of improving the ...
