Zcash is a fork of Bitcoin with optional anonymity features. While transparent transactions are fully linkable, shielded transactions use zero-knowledge proofs to obscure the parties and amounts of the transactions. First, we observe various metrics regarding the usage of shielded addresses. Moreover, we show that most coins sent to shielded addresses are later sent back to transparent addresse...

objective(s): lipid-based nanoparticles (nlp) are pegylated carriers composed of lipids and encapsulated nucleic acids with a diameter less than 100 nm. the presence of peg in the nlp formulation improves the particle pharmacokinetic behavior. the purpose of this study was to prepare and characterize nlps containing mdr1 sirna and evaluate their cytotoxicity and cellular uptake. mdr1 sirna coul...

Shielded conductors permit the transmission of low level signals, at high impedance levels, through areas where excessive interference voltages would be induced into low impedance conductors by low frequency magnetic fields, or in areas where sensitive information must be sent. Shields on wires act the same as shields on rooms, the continuous enclosure acting as a Faraday cage barrier to radiat...

This article presents a software (NMR PROBES) for design NMR probes using closed-forms formulas of the primary and secondary parameters of the shielded split ring [1] and the shielded symmetrical band resonators [2]. These formulas are based on rigorous analysis by finite element method (FEM) [3], [4], method of moment (MoM) [5] and curves fitting techniques. The presented software permits the ...

Various techniques for producing narrow pulse ( f 5 ns) modulation of millimeter wave tubes, such as extended interaction amplifiers, magnetrons, and traveling-wave tubes, are discussed. In order to achieve the narrow pulsewidth, the switch, pulse forming circuitry, as well as the tube interface, must satisfy very stringent requirements. In particular, the switch must operate at kilovolt (kV) l...

An accurate and yet simple simulation technique for optical modulators operating at multi-GHz region and optical modulators are critical for Tera-bps optical communications. This paper describes a simple, efficient and accurate analysis of the travelling wave electrodes for high pseed optical modulation and the implementation of these electrodes in interferometric optical modulators. A finite d...

In this paper we present a newly developed 1700V IGBT and diode chip set generation with optimized performances for 175°C junction temperature operations. The planar 1700V IGBT (SPT+) cell has been improved by exploiting the full potential of the N-enhancement layer with the consequent reduction of the conduction losses. In addition a substantial leakage current reduction has been achieved by d...
