It is now well established that galaxies have different morphologies, gas contents, and star formation rates (SFR) in dense environments like galaxy clusters. The impact of environmental density extends to several virial radii, appear be pre-processed filaments groups before falling into the cluster. Our goal quantify this pre-processing terms content SFR, as a function cosmic filaments. We obs...

This paper presents an approach to calculate the equivalent stray capacitance (SC) of n-turn of the helical flux compression generator (HFCG) coil with multi layer conductor wire filaments (MLCWF) in the form of rectangular cross-section. This approach is based on vespiary regular hexagonal (VRH) model. In this method, wire filaments of the generator coil are separated into many very small simi...

Inside living cells, many essential processes involve deformations of charged helical molecules and the interactions between them. Actin filaments and DNA molecules are important examples of charged helical molecules. In this paper, we consider an impermeable double stranded charged molecule in the solvent. According to the nature, the dielectric constant of the molecule is considerably differe...

We mechanically tested partially phosphorylated vimentin intermediate filaments using optical traps and found that the additional charges considerably soften filaments.

The spatial evolution of plasma filaments in air induced by femtosecond laser pulses is investigated experimentally. Several major filaments and small scaled additional filaments are detected in the plasma channel. The complicated interaction process of filaments as splitting, fusion and spreading is observed. The major filaments propagate stably, and the small scaled additional filaments can b...

Previous studies demonstrated that actin filaments have variable twist in which the intersubunit angles vary by approximately +/- 10 degrees within a filament. In this work we show that this variability was unchanged when different methods were used to prepare filaments for electron microscopy. We also show that actin-binding proteins can modulate the variability in twist. Three preparations of...

We used a glutaraldehyde-tannic acid-saponin fixative to improve the preservation of actin filaments in dividing HeLa cells during preparation for thin sectioning. The contractile ring in the cleavage furrow is composed of a parallel array of actin filaments that circle the equator. We show that many of these actin filaments are arranged in small bundles. These bundles consist of about 25 filam...
