Asymptotic behavior and zero distribution of polynomials orthogonal with respect to Bessel functions [PDF]

, 2015
We consider polynomials P_n orthogonal with respect to the weight J_? on [0,?), where J_? is the Bessel function of order ?. Asheim and Huybrechs considered these polynomials in connection with complex Gaussian quadrature for oscillatory integrals.

Non-Orthogonal Moving Frame for the Kinematics of Parallel Pointing Mechanisms [PDF]

, 2023
A non-orthogonal frame is proposed in this work as an alternative representation of moving frames, which can describe naturally and conveniently orientations of the mobile platform of parallel pointing mechanisms. Fundamentals of non-orthogonal bases are

Descriptors to Dynamics: A Materials and Device Perspective on in‐Materio Physical Reservoir Computing for Neuromorphic Edge Intelligence

Advanced Materials, EarlyView.
Intrinsic material dynamics are harnessed as computational resources for neuromorphic in‐materio physical reservoir computing. Defects, ionic motion, interfaces, percolation, geometry, and biasing shape transient states that provide fading memory, nonlinearity, and high‐dimensional projection for simple readout. A descriptor‐to‐dynamics framework links

Current‐Induced Domain Wall Dynamics in Pt/Co/Ni/Co Nanoribbons With Curvilinear Cross‐Sections

Advanced Materials, EarlyView.
3D curvilinear magnetic racetrack nanoribbons are formed with concave and convex cross‐sections using an advanced multi‐photon 3D printer. The curvature is shown to strongly affect current‐induced domain wall motion along the nanoribbons. In nanoribbons with cross‐sections that have both concave and convex segments, the velocities of domain walls with ...

Inductively Expandable Supraparticles as Microscopic Force Generators for Remote Mechanical Actuation

Advanced Materials, EarlyView.
This study demonstrates the combination of magnetic nanoparticles and functional blowing agents into supraparticles. Upon induction heating, they actuate via rapid gas generation or extensive volume expansion. These supraparticles lift up to 25 000 times their own mass and rapidly open cured epoxy resins, providing a versatile strategy for fast micron ...

Elasticity‐Driven Periodic Polarization Patterns in a Chiral Ferroelectric Nematic Fluid

Advanced Materials, EarlyView.
Chiral polar ferroelectric nematic fluids exhibit spontaneous formation of stripe, square, and hexagonal polarization textures under confinement. Controlled by thickness and anchoring, these patterns produce spatially modulated nonlinear optical responses.

Smarandache ruled surfaces with modified orthogonal frame in R^3

Boletim da Sociedade Paranaense de Matemática
This article introduces a new approach for constructing ruled surfaces in Euclidean 3-space, particularly TN, TB and NB Smarandache ruled surfaces. We investigate their Gaussian and mean curvatures to classify them as developable and minimal surfaces ...
