Purple membranes (PM) are two-dimensional crystals formed by bacteriorhodopsin and a variety of lipids. The lipid composition and density in the cytoplasmic (CP) leaflet differ from those of the extracellular (EC) leaflet. A new way of differentiating the two sides of such asymmetric membranes using the phase signal in alternate contact atomic force microscopy is presented. This method does not...

Chatter vibrations strongly limit productivity in milling. Due to the presence of rotating parts with asymmetric stiffness and stability enhancement strategies which act through a periodic variation stiffness, there is growing interest estimating maps systems Linear Time Periodic dynamics together cutting excitation. Applying Exponentially Modulated test signals dynamic force equation represent...

This paper proposes the stiffness nonlinearities and asymmetric SD (smooth discontinuous) oscillator under time-delayed feedback control with fractional derivative damping. With effect of displacement velocity feedback, can be adjusted to desired vibration state, then stochastic resonance (SR) is achieved. article discusses contribution various system parameters SR, especially which induced by ...

Within the European project e-SAFE (Energy and Seismic AFfordable rEnovation solutions), this paper presents experimental tests modeling attempts for a class of Asymmetric Friction Connections (AFCs) tested in laboratories Norwegian University Life Sciences. The AFCs are part seismic retrofitting solution, called e-CLT, based on installing Cross-Laminated Timber (CLT) panels reinforced concrete...

o bjectives: headgears are among the effective orthodontic appliances to achieve treatment goals. unilateral molar distal movement is sometimes needed during an orthodontic treat- ment, which can be achieved by an asymmetric headgear. different unilateral headgears have been introduced. the main goal of this study was to analyze the force system of uni- lateral expanded outer bow asymmetric hea...

BACKGROUND Vessel diameter is the principal imaging parameter assessed clinically for aortic disease, but adverse events can occur at normal diameters. Aortic stiffness has been studied as an additional imaging-based risk factor, and has been shown to be an independent predictor of cardiovascular morbidity and all-cause mortality. Reports suggest that some aortic pathology is asymmetric around ...

The centrosome is positioned at the cell center by pushing and pulling forces transmitted by microtubules (MTs). Centrosome decentering is often considered to result from asymmetric, cortical pulling forces exerted in particular by molecular motors on MTs and controlled by external cues affecting the cell cortex locally. Here we used numerical simulations to investigate the possibility that it ...

Abstract Eutectic gallium indium liquid metal (LM) is a promising conductive for various electronic applications. In particular, the directional transport of LM droplets has potential applications in soft electronics to control electrical conductivity. Existing methods by applying an electric field generate interfacial tension difference within droplet due nonuniform ionic distribution double l...

In this study an analytical model for linear coupling between the two perpendicular transverse vibration modes in a tightened bolt is presented. The shows excellent fit with experimental data suggesting that dominantly linear. An experiment performed to support linearity claim. Two physical scenarios could justify theoretical given, one scenario involves asymmetric boundary stiffness and other ...
