Direct numerical simulations of three-dimensional surface instability patterns in thin film-compliant substrate structures

open access: yesScientific Reports, 2021
A comprehensive numerical study of three-dimensional surface instability patterns is presented. The formation of wrinkles is a consequence of deformation instability when a thin film, bonded to a compliant substrate, is subject to in-plane compressive ...

Homoclinic snaking in a neutral delay model of a transmission line oscillator [PDF]

open access: yes, 2006
In a transmission line oscillator (TLO) a linear wave travels along a piece of cable, the transmission line, and interacts with terminating electrical components.

Liquid Jetting‐Based Miniature Robotic Navigation in Confined Fluidic Spaces

open access: yesAdvanced Intelligent Systems, Volume 8, Issue 6, June 2026.
We introduce a new class of liquid‐jetting‐based miniature robots (JetBots) ranging in size from mm‐to‐cm, featuring a unified approach in design, fabrication, and actuation. They demonstrate fast locomotion (30.3 cm/s), rapid steering (648.8°/s), and diverse functions, such as puncturing soft materials and unlimited cargo sampling and delivery, paving

HDQ-based solution strategy for in-plane nonlinear buckling of shallow steel arches with linear elastic supports

open access: yesFrontiers in Physics
This paper investigates the in-plane nonlinear buckling of shallow steel arches with linear elastic supports. Differential equations of equilibrium are built considering a virtual work principle. To balance computational accuracy, efficiency, and cost, a

Influence of Imperfections on Axial Buckling Load of Composite Cylindrical Shells [PDF]

open access: yes, 2013
There is a strong requirement for more robust, lighter and cheaper launch vehicle structures. Unstiffened composite cylindrical shells, which are essential to the fabrication of launch vehicle airframes, are prone to buckling and are highly sensitive to ...

A Novel 3D Wiring Technique—ZOLUTION Zero Degree OverLap View Universal Three DimensIONal CTO Wiring

open access: yesCatheterization and Cardiovascular Interventions, Volume 107, Issue 7, Page 2168-2178, June 1, 2026.
ABSTRACT We present a novel simple and easy‐to‐use 3D wiring technique for coronary chronic total occlusions (CTOs) named ZOLUTION—Zero OverLap View Universal Three dimensIONal wiring. ZOLUTION can be used for: (1) Distal cap puncture, (2) CTO body wiring, (3) Retrograde wiring, and (4) Reverse controlled antegrade and retrograde tracking (reverse CART)

Modern analysis of axisymmetric shells with AQUINAS: A MATLAB finite element toolbox

open access: yesSoftwareX, 2023
AQUINAS is a specialised MATLAB finite element (FE) toolbox for the nonlinear analysis of axisymmetric thin-walled shell systems, conceived by the Authors to recover a research functionality once widely available but now largely lost in the age of ...

Non-degenerate umbilics, the path formulation and gradient bifurcation problems [PDF]

open access: yes, 2004
Parametrised contact-equivalence is successful for the understanding and classification of the qualitative local behaviour of bifurcation diagrams and their perturbations. Path formulation is an alternative point of view.

Enhanced sensitivity and tunability of thermomechanical resonance near the buckling bifurcation [PDF]

open access: yes, 2023
The high susceptibility of ultrathin two-dimensional (2D) material resonators to force and temperature makes them ideal systems for sensing applications and exploring thermomechanical coupling.

3D (Bio) Printing Combined Fiber Fabrication Methods for Tissue Engineering Applications: Possibilities and Limitations

open access: yesAdvanced Functional Materials, Volume 36, Issue 40, 18 May 2026.
Biofabrication aims at providing innovative technologies and tools for the fabrication of tissue‐like constructs for tissue engineering and regenerative medicine applications. By integrating multiple biofabrication technologies, such as 3D (bio) printing with fiber fabrication methods, it would be more realistic to reconstruct native tissue's ...
