Linear optimal design of a magnetic repulsion negative stiffness structure

open access: yesJournal of Low Frequency Noise, Vibration and Active Control, 2021
To reduce negative stiffness structure’s stiffness non-linearity, enhance its stability during entire working displacement range, and expand its allowable working displacement, the optimal design of negative stiffness structure based on magnetic ...

Auxetic two-dimensional lattice with Poisson's Ratio arbitrarily close to -1

open access: yes, 2014
In this paper we propose a new lattice structure having macroscopic Poisson's ratio arbitrarily close to the stability limit -1. We tested experimentally the effective Poisson's ratio of the micro-structured medium; the uniaxial test has been performed ...

Clinical Practice Guideline for Evaluation and Management of Peripheral Nervous System Manifestations in Sjögren's Disease

open access: yesArthritis Care &Research, Accepted Article.
Objectives Sjögren's disease is an autoimmune disorder that can impact multiple organ systems, including the peripheral nervous system (PNS). PNS manifestations, which can exist concurrently, include mononeuropathies, polyneuropathies, and autonomic nervous system neuropathies. To help patients and providers in the decision‐making process, we developed

Design and verification of energy balance actuation system for fishbone morphing wings

open access: yes工程科学学报
Morphing wings can improve the aerodynamic performance of aircraft and expand their flight envelope. Elastic deformation of the morphing structure can enable continuous and smooth shape changes of the morphing aircraft, which is important in morphing ...

Application of piezoelectric macro-fiber-composite actuators to the suppression of noise transmission through curved glass plates

open access: yes, 2012
This paper analyzes the possibility of increasing the acoustic transmission loss of sound transmitted through planar or curved glass shells using attached piezoelectric macro fiber composite (MFC) actuators shunted by active circuits with a negative ...

Association Between Symptomatic Knee Osteoarthritis and Target Glycemic Control in Individuals with Type 2 Diabetes

open access: yesArthritis Care &Research, Accepted Article.
Objective Knee osteoarthritis (OA) commonly affects individuals with Type 2 diabetes (T2DM) and is associated with increased risk of diabetes‐related complications. To better understand potential mechanisms, we examined the association between symptomatic knee OA and glycemic control in individuals with T2DM.

Negative stiffness mechanical metamaterials based on curved beams for reusable shock isolation

open access: yesInternational Journal of Smart and Nano Materials
Previous studies on negative stiffness mechanical metamaterials have mainly focused on their quasi-static mechanical properties, while studies on their dynamic mechanical properties are relatively scarce.

Nucleation in a Fermi liquid at negative pressure

open access: yes, 2001
Experimental investigation of cavitation in liquid helium 3 has revealed a singular behaviour in the degenerate region at low temperature. As the temperature decreases below 80 mK, the cavitation pressure becomes significantly more negative.

Point Deflection in Topological Interlocking Plates

open access: yesApplied Sciences
The bending of topological interlocking (TI) plates under point loading is not smooth; it is accompanied by developing lines of localization commensurate with the symmetry of the interlocking assembly.
