With appropriate setup, shielded planar EM (electromagnetic) analysis can be used for antenna analysis. While shielded EM analysis can not handle the variety of antenna problems that unshielded analysis can, shielded analysis offers extreme numerical robustness. This robustness allows, in turn, rigorous identification, quantification, and elimination of analysis error sources. This robustness a...

A local hospital was interested in shielding some sensitive equipment and contemplated installing a shielded room. The room under consideration was the typical laminated wood core panel with galvanized steel on both surfaces, with a RF shielded door, honeycomb air vent panels and filters for ac power, telephone and any other signals, meeting the shielding effectiveness requirements of MIL-STD-2...

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 ...

A technique of irradiating the entire mouse except for one hind limb was developed to provide repeated proliferative demand on the stem cell pool. Animals received 200 cGY weekly for a total dose of 3,400 to 4,000 cGy. During irradiation, shielded bone marrow cellularity was similar to that of unirradiated controls. Shielded marrow colony-forming unit (CFUs) content increased while marrow CFUs ...

introduction the use of cut-outs in electron applicators make changes on output, isodose, and percentage depth dose (pdd) curves. these changes and electron beam dose distribution in the form of three-dimensional (3d) can be measured by gel dosimeters. materials and methods dosimetry was performed with and without a square shield (6×6 cm2 field). the energies were 4, 9, and 16 mev and phantom w...
