DNA under Force: Mechanics, Electrostatics, and Hydration

open access: yesNanomaterials, 2015
Quantifying the basic intra- and inter-molecular forces of DNA has helped us to better understand and further predict the behavior of DNA. Single molecule technique elucidates the mechanics of DNA under applied external forces, sometimes under extreme ...

Impact of the voltage and frequency of a pulse signal applied to a toroidal coil on near magnetic field measurements [PDF]

open access: yesSerbian Journal of Electrical Engineering, 2023
In power electronic systems, electromagnetic radiation of the near field is detrimental because it generates electromagnetic interference in static converters ultimately leading to the degradation of the EMC filter performance.

Experimental study of the behaviour of the crosstalk of shielded or untwisted-pair cables in high frequency [PDF]

open access: yesSerbian Journal of Electrical Engineering, 2019
Electromagnetic disturbances from natural phenomena such as lightning, or those generated from industrial activity, can cause harmful interference in onboard electronic systems.

The influence of plastic deformation and chemical environment on the resistively of al-alloy overhead lines [PDF]

open access: yesSerbian Journal of Electrical Engineering, 2005
The electrical resistively and intensity of X-ray diffraction reflexes were determined for overhead line wires deformed plastically and immersed at different solutions. Immersing (chemical ageing) was performed by plastic deformation along the wire axis.

The effect of three-stage ionization on the structure formation of a concrete mixture during shotcrete

open access: yesНедвижимость: экономика, управление, 2023
The article deals with the problem of reducing rebound and dust formation, as well as increasing the strength of shotcrete. It is known that with “dry” shotcrete, the rebound is especially significant, since the mixture does not have time to acquire ...

Engineering Polymer Interfaces: A Review toward Controlling Triboelectric Surface Charge

open access: yesAdvanced Materials Interfaces, 2023
Contact electrification and triboelectric charging are areas of intense research. Despite their low ability to accept or donate electrons, polymer insulator based triboelectric nanogenerators have emerged as highly efficient mechanical‐to‐electrical ...

Chromatin Compaction Multiscale Modeling: A Complex Synergy Between Theory, Simulation, and Experiment

open access: yesFrontiers in Molecular Biosciences, 2020
Understanding the mechanisms that trigger chromatin compaction, its patterns, and the factors they depend on, is a fundamental and still open question in Biology.

The Hybrid FEM-DBCI for the Solution of Open-Boundary Low-Frequency Problems

open access: yesMathematics, 2021
This paper describes a particular use of the hybrid FEM-DBCI, for the computation of low-frequency electromagnetic fields in open-boundary domains. Once the unbounded free space enclosing the system has been truncated, the FEM is applied to the bounded ...
