Development of single photon source based on micro-ring resonator for quantum memories [PDF]
We design a photon pair source with emission at 606 nm and 3.98 MHz linewidth, which matches the spectral properties of praseodymium ions. To reduce the linewidth the use of cavity-enhanced spontaneous four-wave mixing was proposed.

Neuromyelitis optica (NMO) is a rare autoimmune inflammatory disease of the central nervous system that is characterized mainly by recurrent optic neuritis and longitudinally extensive transverse myelitis. The aim of this article is to present current knowledge on the clinical features, diagnosis, pathogenesis and treatment of the condition.The article

Neuromyelitis optica (NMO), formerly known as Devic disease, is an autoimmune astrocytopathic disease characterized by transverse myelitis and optic neuritis. Most patients demonstrate a relapsing course with incomplete recovery between attacks, resulting in progressive disability.

Partially coherent surface plasmon modes [PDF]
Elementary long-range plasmon modes are described assuming an exponential dependence of the refractive index in the neighbourhood of the interface dielectric-metal thin film. The study is performed using coupling mode theory. The interference between two

Wavelength-tunable picosecond pulses from a passively mode-locked figure-eight Erbium-doped fiber laser with a Sagnac fiber filter [PDF]
We experimentally demonstrated a wavelength-tunable passively mode-locked Erbium-doped figure-eight fiber laser. Wide tunability is achieved using a high-birefringence (hi-bi) fiber Sagnac loop.

Degree of polarization and quantum-mechanical purity [PDF]
The purity parameter is used in quantum mechanics to discriminate pure states from mixed states. We employ this concept to define a degree of polarization for general, three-dimensional, classical random electric fields.

The discovery of serum autoantibodies against the astrocytic water channel aquaporin-4 (AQP4) as a biomarker of neuromyelitis optica (NMO, Devic syndrome) has revolutionized our understanding of this rare immune-mediated clinical entity and has provided a rationale for the use of therapeutic strategies targeting the humoral effector arm of autoimmune ...
