Harmonic mappings between surfaces : some local and global properties [PDF]
We develop some local and global properties of a harmonic map f :M -> N between surfaces. Our first main result is a local description of the possible singularities of such a harmonic map - we find there are four types: degeneracy, general fold ...

Elastic–Plastic Modeling and Experimental Characterization of Granular Jamming Actuators
Granular jamming enables rapid switching between soft and rigid mechanical states. Here, a reduced‐order elastic‐perfectly‐plastic beam framework captures pressure‐dependent loading, unloading, residual deformation, and hysteresis in jammed beams, while matching three‐point bending experiments across materials and geometries. The framework links design

Harmonic analysis for spinors on real hyperbolic spaces
International audienceWe develop the $L^2$ harmonic analysis for (Dirac) spinors on the real hyperbolic space $H^n(\mathbb{R})$ and give the analogue of the classical notions and results known for functions and differential forms: we investigate the ...

A hybrid additive manufacturing platform integrates direct droplet writing of metallic composite with VAT photopolymerization to fabricate architected soft magnetic composites. This approach enables microscale patterning of high‐viscosity materials for programmable actuators, adaptive fluidic devices, and switchable adhesives, offering tunable ...

Harmonic Singular Integrals and Steerable Wavelets in $ L _{ 2 } $ $ (\mathbb{R} ^{ d } $ )
Here we present a method of constructing steerable wavelet frames in $ L _{ 2 } $ $ (\mathbb{R} ^{ d } $ ) that generalizes and unifies previous approaches, including Simoncelli's pyramid and Riesz wavelets.

Harmonic diffeomorphisms of noncompact surfaces and Teichmüller spaces [PDF]
Let g : M -> N be a quasiconformal harmonic diffeomorphism between noncompact Riemann surfaces M and N. In this paper we study the relation between the map g and the complex structures given on M and N.

A signal-strength model for gravity-field spectrum components in a local space
In the Earth gravity-field model, potential coefficients are projections of the Earth gravitational potential on the corresponding spherical harmonics by degree and order.
