-A nematic layer with opposite boundary conditions (unidirectional planar and homeotropic) is considered, having strong anchoring at the planar wall. It is known that a periodic deformation of splay-type can intervene between the aperiodic hybrid alignment and undistorted planar state as one decreases the film thickness. This periodic state occurs due to the fact that the energetic cost for a m...

We found a rotating global structure induced by the dynamical force of local chemical activity in a thin solution layer of excitable Belousov-Zhabotinsky reaction coupled with diffusion. The surface flow and deformation associated with chemical spiral waves (wavelength about 1 mm) represents a global unidirectional structure and a global tilt in the entire Petri dish (100 mm in diameter), respe...

Understanding of the failure composites is critical for evaluating their safety and reliability when they are in service. In this research, a combined image analysis technique using computed microtomography (micro-CT) scanning electron microscopy (SEM) proposed to study microstructures, damage hybrid unidirectional/woven composite laminate (HUWCL). Micro-CT used extract 3D microscale morphology...

Bioinspired Interfaces fluid transporting interfaces provide a promising strategy to simplify the current systems. In article number 2211596, Moyuan Cao and co-workers present superhydrophilic origami with dual-asymmetric channels realize spontaneous, unidirectional, adaptive, gravity-independent fluid-collection process. The further integration of radiative layer can improve fog steam collecti...

We predict a spin anomalous-Hall unidirectional magnetoresistance (AH-UMR) in conducting bilayers composed of ferromagnetic layer and nonmagnetic layer, which does not rely on the Hall effect normal metal layer---in stark contrast to well-studied spin-Hall magnetoresistance---but instead arises from anomalous layer. Physically, it is charge-spin conversion induced by that conspires with structu...

The motor cortex (M1) is classically considered an agranular area, lacking a distinct layer 4 (L4). Here, we tested the idea that M1, despite lacking a cytoarchitecturally visible L4, nevertheless possesses its equivalent in the form of excitatory neurons with input-output circuits like those of the L4 neurons in sensory areas. Consistent with this idea, we found that neurons located in a thin ...

In wireless networks, the physical medium is the cause of most of the errors and performance drops. Thus, an efficient predictive estimation of wireless networks performance w.r.t. medium status by the communication peers would be a leap ahead in the improvement of wireless communication. For that purpose, we designed a measurement bench that allows us to accurately control the noise level on a...

We analyze a multi-type age dependent model for cell populations subject to unidirectional motion, in both a stochastic and deterministic framework. Cells are distributed into successive layers; they may divide and move irreversibly from one layer to the next. We adapt results on the large-time convergence of PDE systems and branching processes to our context, where the Perron-Frobenius or Krei...

We report an investigation on the antiferromagnetic layer thickness dependence of magnetization reversal in c-axis oriented MnPd/Fe epitaxial exchange biased bilayers. Several kinds of multistep loops were observed for different samples measured at various field orientation. The evolution of the angular dependent magnetic behavior evolving from a representative Fe film to the exchange biased bi...

Abstract The non-linear analysis of any physical problem is capable of predicting the qualitative and quantitative aspects of the problem. In this article, the effects of the constraints like rotation, permeability and quadratic density profile on unidirectional solidification with buoyancy and small segregation coefficient were investigated using nonlinear theory. In this study, the system con...
