Transport of cargo by molecular motors on microtubule and actin filament tracks is a fundamental property of eukaryotic cells. A new study reports that actin dynamics are required in cells for myosin I and V motor proteins to transport their organelle cargos on actin tracks.

In this paper, we present early considerations on the design of a multimedia transport service. The proposed design provides not only support for Quality of Service (QoS) and group communications, but also has the property to treat multimedia communications \as a whole". This diiers from most of the current transport services which transfer multimedia data as several independent monomedia.

In this article, the transport operator with general boundary conditions is discussed. According to a smallness hypothesis on the boundary operator and to finite time of sojourn property of phase spaces, we prove that the transport operator generates a strongly continuous semigroup and we give its upper bound.

fe3o4 nanostructures were synthesized via a facile hydrothermal reaction. the effect of various surfactants such as cationic and anionic on the morphology of the product was investigated. magnetic nanoparticles were added to poly styrene (ps) for preparation of magnetic nanocomposite. nanostructures were then characterized using x-ray diffraction (xrd), scanning electron microscopy (sem) and fo...

Emerging trend in semiconductor nanotechnology motivates to design various crystalline nanotubes. The structural and electronic transport properties of single walled zigzag Gallium Arsenide nanotubes have been investigated using Density Functional Theory (DFT) and Non-Equilibrium Green’s Function (NEGF) based First Principle formalisms. Structural stability and enhanced electronic transmission ...

Carbon quantum dots (CQDs) serve as a new class of ‘zero dimensional’ nanomaterial’s in thecarbon class with sizes below 10 nm. As light emitting nanocrystals, QDs are assembled from semiconductormaterials, from the elements in the periodic groups of II-VI, III-V or IV-VI, mainly thanks to impacts of quantum confinement QDs have unique optical properties such as brighter, highly pho...

We study the coherent spin-polarized transport through a zigzag-edge graphene flake (ZGF), using Hubbard model in the nearest neighbor approximation within the framework of the Green function’s technique and Landauer formalism. The system considered consists of electrode/ (ZGF)/electrode, in which the electrodes are chosen to be armchair nanoribbons. The study was performed for two types of ele...

Nanomaterials have achieved remarkable technological advances in bulk materials due to their excellent physical, chemical and biological properties. cerium oxide (CeO2) nanostructured doped with Fe ions is attractive due to improvement in redox properties, transport property and surface-to-volume ratio. In this research, Fe-doped CeO2 nanoparticles (NPs) were prepared by s...

The phonon transport property is a foundation of understanding a material and predicting the potential application in mirco/nano devices. In this paper, the thermal transport property of borophene is investigated by combining first-principle calculations and phonon Boltzmann transport equation. At room temperature, the lattice thermal conductivity of borophene is found to be about 14.34 W/mK (e...
