Efficient and Robust Standing Postures of Quadruped Robots
Advanced Robotics Research, EarlyView.A calibrated static framework estimates load, optimizes torques, and adapts posture so quadruped robots stand efficiently and robustly under external payloads, achieving up to 50% lower torque demand. Inspired by the natural posture adjustments of animals under external loading, this article presents an optimization‐based framework for minimizing joint

On the geometry of quadratic maps of the plane
, 2013 In this article we give a geometric classification of the set of quadratic maps of the plane. The fundamental step is the proof that the restriction of the map to the critica!

Nonperturbative double copy: worldline instantons, color thermality, and backreaction
Journal of High Energy PhysicsWe present a first-principles, non-perturbative worldline instanton analysis of vacuum decay in the non-abelian Yang-Mills root of a Schwarzschild background. We recover the gauge theory color-thermal spectrum as a topological winding mode.

Advanced Robotics Research, EarlyView.Functional surfaces are investigated as a foundation for reconfigurable microscale systems with sensing and actuation capabilities. Advances in additive manufacturing enable our development of planar arrays of hybrid‐material, compliant microdevices that convert environmental stimuli into programmed motion and visual responses.

A family of quadratic forms associated to quadratic mappings of spheres
Linear Algebra and its Applications, 1985 Let \((U,q_ U)\) and \((V,q_ V)\) be real positive definite quadratic spaces of dimension n and m respectively, n,m\(\geq 2\). Furthermore let \(S_ U\subset U\), \(S_ V\subset V\) denote the corresponding spheres and S(U,V) the set of quadratic maps f:U\(\to V\) such that \(q_ V(f(x))=q_ U(x)^ 2\) for all \(x\in U\).

Consensus Formation and Change are Enhanced by Neutrality
Advanced Science, EarlyView.Neutral agents are shown to enhance both the formation and overturning of consensus in collective decision‐making. A general mathematical model and experiments with locusts and humans reveal that neutrality enables robust consensus via simple interactions and accelerates consensus change by reducing effective population size.

Solid Harmonic Wavelet Bispectrum for Image Analysis
Advanced Science, EarlyView.The Solid Harmonic Wavelet Bispectrum (SHWB), a rotation‐ and translation‐invariant descriptor that captures higher‐order (phase) correlations in signals, is introduced. Combining wavelet scattering, bispectral analysis, and group theory, SHWB achieves interpretable, data‐efficient representations and demonstrates competitive performance across texture,
