Pattern Formation in Non‐Equilibrium Architected Materials
Advanced Materials Technologies, EarlyView.This article demonstrates an artificial mechanical system ‐ a robotic metamaterial ‐ as an accessible and versatile platform within which to explore and prescribe the reaction‐diffusion driven pattern formation hitherto associated with comparatively less accessible and versatile non‐equilibrium biological and chemical systems.

Étude géométrique et topologique du flot géodésique sur le groupe des rotations [PDF]
Surveys in Mathematics and its Applications, 2016 The aim of this survey paper is to investigate the algebraic complete integrability of Euler-Arnold's body description of the four dimensional rigid body, or equivalently of geodesics in SO(4) using left-invariant metrics that arise from inertia tensors,

Development of Laterally Graded X‐Ray Multilayer Optics
Advanced Materials Technologies, EarlyView.This work presents the development of laterally graded X‐ray multilayer optics with both constant and variable lateral gradients. By precisely controlling substrate speed profiles and mask design, these multilayers achieve highly accurate lateral gradients and excellent sagittal thickness uniformity, making them ideal for spectroscopy application at ...

On a Theorem of Ziv Ran concerning Abelian Varieties Which Are Product of Jacobians
Journal of Mathematics, 2015 We give a new proof for a theorem of Ziv Ran which generalizes some results of Matsusaka and Hoyt. These results provide criteria for an Abelian variety to be a Jacobian or a product of Jacobians. The advantage of our method is that it works in arbitrary

Journal of Pure and Applied Algebra, 1991 [For part I see ibid. 72, No. 1, 39-51 (1991; Zbl 0747.13014).] This work concerns the Jacobian conjecture. Let \(k\) be an algebraically closed field of characteristic zero. A pair of polynomials \(f,g\in k[X,Y]\) is said to be a Jacobian pair if \({\partial f\over\partial X}{\partial g\over\partial Y}-{\partial f\over\partial Y}{\partial g\over ...

Advanced Robotics Research, EarlyView.A codesign multiobjective optimization framework was developed to enhance the morphology and controller of a snake‐like robot driven by artificial muscles. It improved planar locomotion, agility, and power efficiency. The approach optimized link geometry and controller gains, revealing that shorter muscles near joints and longer linkages maximize ...

Equivariant geometry of singular cubic threefolds
Forum of Mathematics, SigmaWe study linearizability of actions of finite groups on singular cubic threefolds, using cohomological tools, intermediate Jacobians, Burnside invariants, and the equivariant Minimal Model Program.

Non-supersingular hyperelliptic jacobians [PDF]
Bulletin de la Société mathématique de France, 2004 In his previous papers the author proved that in characteristic different from 2 the jacobian J(C) of a hyperelliptic curve C: y^2=f(x) has only trivial endomorphisms over an algebraic closure K_a of the ground field K if the Galois group of the irreducible polynomial f(x) in K[x] is either the full symmetric group S_n or the alternating group A_n ...

Material‐Induced Nuclear Deformation Controls Chromatin Architecture in Adipose Stem Cells
Advanced Science, EarlyView.Tuning cell and cytoskeleton mechanics modulated nuclear shape and heterochromatin organization in ASCs. Distinct cytoskeletal architectures induced nuclear morphologies from oblate to prolate ellipsoids. Large elongated cells with a structured actin cap exhibited high nuclear strain, driving nuclear envelope deformation and heterochromatin ...
