Eukaryotic cells possess a sensible chemical compass allowing them to orient toward sources of soluble chemicals. The extracellular chemical signal triggers separation of the cell membrane into two domains populated by different phospholipid molecules and oriented along the signal anisotropy. We propose a theory of this polarization process, which is articulated into subsequent stages of germ n...

A number of previous studies have extensively investigated directional anisotropy in motion perception. However, consensus has not been reached regarding the nature of motion directional anisotropies in human vision. In this study, we investigated the directional anisotropy of human motion perception by moving random-dot stimuli in the peripheral upper visual field. Our findings show that the d...

This article describes a numerical study on the TOX-clinching process of the steel sheets. In addition, the influence of plastic anisotropy of the material on joining parameters is analyzed by evolution of the joint parameters such as undercut and neck thickness and punch force-displacement curve. Finite element analysis with ABAQUS/CAE-Explicit program is used to simulate two dimensional and t...

Background: People occasionally undergo medical diagnostic X-ray examinations and expose their red blood cells to radiation. Radiation that is generated from medical diagnostic X-ray machines is widely used in medical diagnoses. One of the important parameters is kilo-voltage (kV) that is applied across the X-ray tube in medical diagnostic X-ray machines. Kilo-voltage influences the radiation d...

Inverse methods are used to reconstruct current sources in the human brain by means of Electroencephalography (EEG) and Magnetoencephalography (MEG) measurements of event related fields or epileptic seizures. There exists a persistent uncertainty regarding the influence of anisotropy of the white matter compartment on neural source reconstruction. In this paper, we study the sensitivity to anis...

The current transport in polycrystalline MgB2 is strongly influenced by the intrinsic anisotropy of this superconductor. Untextured bulks and wires are macroscopically isotropic, but the grains retain their anisotropic properties and the field dependence of the critical currents is much stronger than in isotropic superconductors. Weakly or partially textured tapes are macroscopically anisotropi...

Granular anisotropy is attributable to many complex behaviors of granular materials and reflects important microstructures at the grain scale, and should be fully considered towards the development of realistic constitutive models for such materials. In this paper, we present a study on the behavior of anisotropy using a three-dimensional Discrete Element Method (DEM). Isotropic packings of san...

Universality classes of Ising-like phase transitions are investigated in series of two-dimensional synchronously updated probabilistic cellular automata (PCAs), whose time evolution rules are either of Glauber type or of majority-vote type, and degrees of anisotropy are varied. Although early works showed that coupled map lattices and PCAs with synchronously updating rules belong to a universal...
