Structural flexibility of human α‐dystroglycan

open access: yesFEBS Open Bio, 2017
Dystroglycan (DG), composed of α and β subunits, belongs to the dystrophin‐associated glycoprotein complex. α‐DGis an extracellular matrix protein that undergoes a complex post‐translational glycosylation process. The bifunctional glycosyltransferase like‐acetylglucosaminyltransferase (LARGE) plays a crucial role in the maturation of α‐DG, enabling its

Behaviour of soil-steel composite structures during construction and service: a review [PDF]

open access: yesArchives of Civil Engineering, 2023
In this paper, existing knowledge on the behaviour of soil-steel composite structures (SSCSs) has been reviewed. In particular, the response of buried corrugated steel plates (CSPs) to static, semistatic, and dynamic loads has been covered.

Deflection Sliding Mode Control of a Flexible Bar Using a Shape Memory Alloy Actuator with an Uncertainty Model

open access: yesApplied Sciences, 2020
This paper presents a penalty-based sliding mode control (SMC) law for flexible bar system, which uses shape memory alloy (SMA) as actuator. SMA actuators are lightweight, compact and flexible which facilitate their integration into flexible structures ...

Experimental Investigation on Integrated Subsurface Monitoring of Soil Slope Using Acoustic Emission and Mechanical Measurement

open access: yesApplied Sciences, 2021
Compared with slope surface measurement, subsurface monitoring has the potential to detect abnormal changes at an earlier stage. Due to the large-scale deformation of landslides and the complex geological environment, the existing subsurface devices ...

Economic Flexibility: A Structural Analysis [PDF]

open access: yes, 2007
Economic flexibility is much discussed in the academic literature but has no agreed definition. In neoclassical economics, a flexible economy can be secured only by removing structural rigidities that block relative price movements and hamper the operation of markets – social structures are seen as a threat to flexibility.

Reduction of degrees of Freedom in three-dimensional ANCF beam of 24-DOF beam element by component mode synthesis

open access: yesNihon Kikai Gakkai ronbunshu, 2014
This paper describes how to reduce degrees of freedom for the absolute nodal coordinate formulation (ANCF) of three-dimensional beam made up of 24 degrees of freedom beam elements by applying the component mode synthesis. The stiffness matrix of the ANCF
