The conventional wisdom is that optical fiber is dielectric, and thus does not radiate RF emissions. In practice, optical fiber cable connectors have non-negligible amounts of conductive material, for example a ferrule, spring, and crimp ring. As data rates have increased beyond 1 gigabit/second (Gbps), equipment with supposedly “RF tight” enclosures exhibited high levels of RF emissions, faili...

Abstract We investigate fixed energy scattering from conical potentials having an irregular cross-section. The incident wave can be arbitrary non-trivial Herglotz wave. show that a large number of such local scatterers scatter all waves, meaning the far-field will always non-zero. In essence there are no waves for which these would seem transparent at any given energy. more specifically is coll...

The annual mortality of cultured Japanese pearl oysters Pinctada fucata martensii in all western regions of Japan was over 400 million in both 1996 and 1997. The main pathological signs of the diseased oysters were atrophy in the adductor muscle, the mantle lobe and the body accompanied by a yellowish to brown coloration. Histological studies revealed necrosis and degeneration of muscle fibers ...

Indonesia has a high potential for pearl oyster farming due to its diverse marine habitats, warm waters, and abundant supply of seaweed, which is the preferred food oysters. home several species oysters, including Pinctada maxima, are prized their large size quality pearls. Water plays crucial role in cultivation maxima. Factors such as temperature, pH, salinity, dissolved oxygen levels, presen...

A new argument is presented confirming the point of view that a Schwarzshild black hole formed during a collapse process does not radiate.
