An analytical formulation has been developed to evaluate the shielding effectiveness (SE) of two coplanar rectangular metallic enclosures with a circular aperture excited by an internal electric dipole source. The formulation consists of three parts: First, the near-field electromagnetic interference (EMI) of the electromagnetic leakage from the aperture is represented by the electric dipole in...

Fluctuations in the bending angles at internal irregularities of DNA and RNA (such as symmetric loops, bulges, and nicks/gaps) have been observed from various experiments. However, little effort has been made to computationally predict and explain the statistical behavior of semi-flexible chains with internal defects. In this paper, we describe the general structure of these macromolecular chai...

Against the detrimental effects of ionizing radiation, time, distance, and shielding are three most significant protective methods. Lead is material choice for shielding, particularly personal equipment. However, lead's density, rigidity, toxicity disadvantages. In recent years, tungsten-containing rubber (TCR) other lightweight, flexible, non-toxic materials have emerged as viable alternatives...

With the booming growth of flexible human-computer interactions and telecommunications, it is desirable to fabricate a high-sensitivity strain sensor monitor human movement develop an electromagnetic interference (EMI) shielding materials protect modern microelectronics humans from damage. Herein, biocompatible, stretchable, compressible cellulose/MXene hydrogel has been prepared first realize ...

PEGylation is a successful approach to improve potency of a therapeutic protein. The improved therapeutic potency is mainly due to the steric shielding effect of PEG. However, the underlying mechanism of this effect on the protein is not well understood, especially on the protein interaction with its high molecular weight substrate or receptor. Here, experimental study and molecular dynamics si...

Reactivity studies of the classical divalent lanthanide compound [CpBz52Sm] (CpBz5 = pentabenzylcyclopentadienyl-anion) towards diphenyl dichalcogenides and d-element carbonyl complexes led to remarkable results. In compounds obtained, a different number Sm-C(phenyl) interactions differently oriented benzyl groups were observed, suggesting—despite preference these in described previous studies—...

PURPOSE The integration of a low field biplanar magnetic resonance (MR) imager and linear accelerator (linac) causes magnetic interference at the linac due to the MR fringe fields. In order to eliminate this interference, passive and active magnetic shielding designs are investigated. METHODS The optimized design of passive magnetic shielding was performed using the finite element method. The...

This article provides a thorough description of range non-standard application cases in which EMC laboratories can be used other than those traditionally associated with this kind facilities. The areas covered here include investigations of: wireless and radio systems (such as IoT broadband systems) also that require ultra-high operational dynamic range, emulation interference-free and/or heavi...
