Physical Review E, 2011 We study the mechanical buckling of a two dimensional membrane coated with a thin layer of superfluid. It is seen that a singularity (vortex or anti-vortex defect) in the phase of the quantum order parameter, distorts the membrane metric into a negative ...

Flexible filaments buckle into helicoidal shapes in strong compressional flows [PDF]
Nature Physics, 2019 The occurrence of coiled or helical morphologies is common in nature, from plant roots to DNA packaging into viral capsids, as well as in applications such as oil drilling processes.

Buckling of swelling gels [PDF]
The European Physical Journal E, 2006 The patterns arising from the differential swelling of gels are investigated experimentally and theoretically as a model for the differential growth of living tissues. Two geometries are considered: a thin strip of soft gel clamped to a stiff gel, and a thin corona of soft gel clamped to a disk of stiff gel. When the structure is immersed in water, the

Nonlinear Euler buckling [PDF]
Proceedings of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2008 The buckling of hyperelastic incompressible cylindrical tubes of arbitrary length and thickness under compressive axial load is considered within the framework of nonlinear elasticity. Analytical and numerical methods for bifurcation are developed using the exact solution of Wilkes for the linearized problem within the Stroh formalism.

Are Unnecessary Serial Radiographs Being Ordered in Children with Distal Radius Buckle Fractures?
Radiology Research and Practice, 2018 Background. Torus or buckle distal radius fractures are common injuries in the pediatric population. By definition, they are stable and can be treated conservatively with a wrist splint or soft crepe bandage. Objective. The objective of this study was to

Soft Matter, 2010 We report experiments on the deformation and transport of an elastic fiber in a viscous cellular flow, namely a lattice of counter-rotative vortices. We show that the fiber can buckle when approaching a stagnation point. By tuning either the flow or fiber properties, we measure the onset of this buckling instability.

Current concepts of macular buckle in myopic traction maculopathy
Indian Journal of Ophthalmology, 2018 Since its introduction by Charles L. Schepens, macular buckle (MB) surgery has evolved over the past 60 years. Optical coherence tomography (OCT) has given a paradigm shift to the understanding of myopic macula, thereby helping in objective evaluation of

On Buckling Morphogenesis [PDF]
Journal of Biomechanical Engineering, 2016 Cell-generated mechanical forces drive many of the tissue movements and rearrangements that are required to transform simple populations of cells into the complex three-dimensional geometries of mature organs. However, mechanical forces do not need to arise from active cellular movements. Recent studies have illuminated the roles of passive forces that

British Journal of Ophthalmology, 2017 Purpose To evaluate the efficacy of a combined macular buckle under direct vision and 23-gauge pars plana vitrectomy (PPV) with internal limiting membrane (ILM) peeling in refractory macular hole retinal detachment (MHRD) with extreme high axial myopia ...

Buckling of spherical capsules [PDF]
Physical Review E, 2011 We investigate buckling of soft elastic capsules under negative pressure or for reduced capsule volume. Based on nonlinear shell theory and the assumption of a hyperelastic capsule membrane, shape equations for axisymmetric and initially spherical capsules are derived and solved numerically.
