Adaptable Tile‐Based Pneumatic Origami through Structurally Coupled Localized Actuation

Advanced Engineering Materials, EarlyView.
This article presents tile‐based pneumatic origami structures with rigid tiles and flexible fabric creases, achieving adaptable properties including morphing shape, selective multistability, and tunable stiffness. Independently pressurized folding bladders at each crease enable structurally coupled localized actuation of origami structures.

Patient-specific gait pattern in individuals with patellofemoral instability reduces knee joint loads

Scientific Reports
Patellofemoral instability is influenced by morphological factors and associated with compensational alterations in gait pattern. Recent simulation studies investigated the impact of knee morphology on the stability and loading of the patellofemoral ...

Cellular buckling in stiffened plates [PDF]

, 2014
An analytical model based on variational principles for a thin-walled stiffened plate subjected to axial compression is presented. A system of nonlinear differential and integral equations is derived and solved using numerical continuation.

Advancing Research on Biomaterials and Biological Materials with Scanning Electron Microscopy under Environmental and Low Vacuum Conditions

Advanced Engineering Materials, EarlyView.
Herein, environmental scanning electron microscopy (ESEM) is discussed as a powerful extension of conventional SEM for life sciences. By combining high‐resolution imaging with variable pressure and humidity, ESEM allows the analysis of untreated biological materials, supports in situ monitoring of hydration‐driven changes, and advances the functional ...

Joint dislocation [PDF]

, 2014
A joint dislocation, or luxation occurs when there is an abnormal separation in the joint, where two or more bones meet. A partial dislocation is referred to as a subluxation.

Unconventional Fermi surface instabilities in the Kagome Hubbard Model

, 2012
We investigate the competing Fermi surface instabilities in the Kagome tight-binding model. Specifically, we consider onsite and short-range Hubbard interactions in the vicinity of van Hove filling of the dispersive Kagome bands where the Fermiology ...

Non-linearity and Non-Gaussianity through Phase Information [PDF]

, 2000
In the standard picture of structure formation, initially random-phase fluctuations are amplified by non-linear gravitational instability to produce a final distribution of mass which is highly non-Gaussian and has highly coupled Fourier phases.

Scapular Instability: The Scapulothoracic Joint

Physical Medicine and Rehabilitation Clinics of North America, 2000
Scapular instability may be the result of a variety of casues of which the clinician should be made aware. Work-up should include an initial radiographic evaluation and may require more in-depth investigation. Treatment should be prescribed dependent on the underlying diagnosis. In most cases, instability about the scapula can be treated with a careful

3D‐Printed Serial Snap‐Through Architectures for Programmable Mechanical Response

Advanced Engineering Materials, EarlyView.
A serial snap‐through architecture is realized using compact 3D‐printed von Mises truss units arranged in a staged cascade. Their geometry and boundary conditions program multistage mechanical responses with plateaux and re‐hardening regimes. An inverted‐compliance model predicts these behaviors and enables analytical design of programmable force ...
