The low Young's modulus of biological particles results in their large deformation against the AFM probe forces; therefore, it is necessary to study the contact mechanics of bioparticles in order to predict their mechanical behaviors. This paper specifically deals with the contact mechanics of DNA nanoparticles with spherical and cylindrical shapes during manipulation. In previous studies, ...

STEREO A and B observations of the radial magnetic field between 1 January 2007 and 31 October 2008 further show significant evidence that in the heliosphere, the ambient radial magnewtic field component with any dynamic effects removed is uniformly distributed. Based on this monopolar nature of the ambient heliospheric field we find that the surface beyond which the magnetic fields are in the ...

We analyze the relationship between the mass of a spherical component and the minimum possible thickness of stable stellar disks. This relationship for real galaxies allows the lower limit on the dark halo mass to be estimated (the thinner the stable stellar disk is, the more massive the dark halo must be). In our analysis, we use both theoretical relations and numerical N-body simulations of t...

In this work, we derive the well-established expression for the quantum amplitude associated with the resonance energy transfer (RET) process between a pair of molecules that are beyond wavefunction overlap. The novelty of this work is that the field of the mediating photon is described in terms of a spherical wave rather than a plane wave. The angular components of the field are constructed in...

Abstract. This paper is an attempt to respond the growing need and demand of 3D data in forestry, especially for mapping. The use terrestrial laser scanners (TLS) dominates contemporary literature under-storey vegetation mapping as this technique provides precise easy-to-use solutions users. However, TLS requires substantial investments terms device acquisition user training. search development...
