Based on the high-resolution electromagnetic field intensity observed by DEMETER satellite, harmonic radiations in ionosphere closely above extra-high voltage and ultra-high power projects Chinese grid have been detected. In time-frequency spectrograms, these are characterized parallel spectral lines with spacings of 50, 100, 150, or 600 Hz. The highest frequency can reach approximately 8,850 p...

The property profile exhibited by cellular metals identifies several applications, especially in technologies requiring multifunctionality. Their specific property attributes suggest implementation as: ultralight panels/shells, energy absorbing structures and heat dissipation media as well as for vibration control. Connections between the properties that govern these performance benefits and th...

We study the Mifare Ultralight cards in detail, and we present a new secure method for the recharge of these RFID disposable tickets that also extends to the case of multiple resources on a single device. We specify a formal but yet realistic semantics of these cards, and we also define a simple imperative language suitable to program secure APIs. In fact, the language is provided with a type-s...

We propose a scenario in which dark energy and dark matter are described in a unified manner. The ultralight pseudo-Nambu-Goldstone (pNG) boson, A, naturally explains the observed magnitude of dark energy, while the bosonic supersymmetry partner of the pNG boson, B, can be a dominant component of dark matter. The decay of B into a pair of electron and positron may explain the 511 keV γ ray from...

Supersymmetric (SUSY) standard models in which the lightest SUSY particle (LSP) is an ultralight gravitino (m3/2 = O(1) eV) are very attractive, since they are free from the cosmological gravitino problems. If the neutralino is the next lightest SUSY particle (NLSP), it decays into a photon and the gravitino in collider experiments. We propose a simple test for the lightness of gravitino at the...

We reconsider entropy arguments which have been previously argued to support the idea that dark matter constituents are primordial black holes with many solar masses. It has recently shown QCD axions solve strong CP problem may masses [Formula: see text] in extended range text]. Ultralight provide so degrees of freedom their can exceed holes. This suggests ultralight more suited than be matter.

Fuji Electric has developed processes to fabricate ICs. The process satisfies demands for a display driver IC of up to about 100V for a liquid crystal display (LCD), plasma display panel (PDP) and vacuum fluorescent display (VFD). The power control IC has up to about 40V of high voltage and high current analog signal control. The ICs are fabricated using the CMOS (complementary MOS) oxide isola...
