Acoustic‐driven surface cleaning with millimeter‐sized bubbles at translational resonance
Droplet, EarlyView.Time‐lapse visualization comparing bubble trajectories. The top panel (0 Hz) shows a bubble's linear path under no acoustic forcing, while the bottom panel (50 Hz) demonstrates the oscillatory motion induced by acoustic waves at a resonance mode. This mechanism holds promising potential for applications such as surface cleaning.

Second order tangent sets [PDF]
, 2009 The second order tangent sets play an important role in establishing second order optimality conditions, but, despite of the rst order tangent cone, properties of such sets have not been studied in a systematic way. The aim of this paper is to present

Earthquake Engineering &Structural Dynamics, EarlyView.ABSTRACT Rocking podium isolation systems have gained significant research interest as a method of limiting seismic demands on superstructures and eliminating residual post‐earthquake drifts through self‐centring behaviour. However, while numerous models of varying complexity, including analytical, phenomenological, and physical formulations, have been

The tangent cone to the real determinantal variety: various expressions and a proof [PDF]
The set of real matrices of upper-bounded rank is a real algebraic variety called the real generic determinantal variety. An explicit description of the tangent cone to that variety is given in Theorem 3.2 of Schneider and Uschmajew [SIAM J.

Scribbling continua in Rn and constructing singularities with prescribed Nash fibre and tangent cone [PDF]
, 1995 Using approximations in the Hausdorff metric, we prove that any continuum in Rn is the set of limits at infinity of a real-analytic curve. This is then used to solve a problem concerning the characterization of the Nash fibre and the tangent cone of ...

FlexMat, EarlyView.Abstract Soft robots, engineered from highly compliant materials, offer superior adaptability and safety in unstructured environments compared to their rigid counterparts. Recent advancements, fueled by bio‐inspiration and material programmability, have led to the rapid co‐evolution of their core modules: actuation, sensing, protection, energy, and ...

Generalization of p-regularity notion and tangent cone description in the singular case [PDF]
, 2016 The theory of p-regularity has approximately twenty-five years’ history and many results have been obtained up to now. The main result of this theory is description of tangent cone to zero set in singular case.
