Multiplex Modular Nanorobotic Systems with Catalytic Activity under Magnetic Navigation
Advanced Functional Materials, EarlyView.We present modular nanorobots composed of a magnetic propulsion module and different extension modules carrying functional activities, assembled via DNA base pairing. The system integrates propulsion, optical tracking, enzymatic catalysis, and cell docking in a programmable manner.

Searching for integrable Hamiltonian systems with Platonic symmetries [PDF]
, 2010 In this paper we try to find examples of integrable natural Hamiltonian systems on the sphere $S^2$ with the symmetries of each Platonic polyhedra. Although some of these systems are known, their expression is extremely complicated; we try here to find ...

A generalization of the S-function method applied to a Duffing-Van der Pol forced oscillator
, 2017 In [1,2] we have developed a method (we call it the S-function method) that is successful in treating certain classes of rational second order ordinary differential equations (rational 2ODEs) that are particularly `resistant' to canonical Lie methods and

Integral polytopes and polynomial factorization
Turkish Journal of Mathematics, 2013 For any field F, there is a relation between the factorization of a polynomial f \in F[x1,...,xn] and the integral decomposition of the Newton polytope of f. We extended this result to polynomial rings R[x1,...,xn] where R is any ring containing some elements which are not zero-divisors.

Advanced Functional Materials, EarlyView.A MXene/PEDOT coating enables multimodal functionality and dual‐analyte detection of dopamine and serotonin in flexible microelectrode arrays while enhancing electrophysiological recording quality. The anti‐fouling, low‐impedance interface overcomes key limitations of conventional coatings, providing a robust and versatile platform to investigate the ...

Singularities and growth of higher order discrete equations [PDF]
Open Communications in Nonlinear Mathematical PhysicsWe study the link between the degree growth of integrable birational mappings of order higher than two and their singularity structures. The higher order mappings we use in this study are all obtained by coupling mappings that are integrable through ...

Deforming the Lie algebra of vector fields on $S^1$ inside the Poisson algebra on $\dot T^*S^1$
, 1997 We study deformations of the standard embedding of the Lie algebra $\Vect(S^1)$ of smooth vector fields on the circle, into the Lie algebra of functions on the cotangent bundle $T^*S^1$ (with respect to the Poisson bracket). We consider two analogous but

Advanced Healthcare Materials, EarlyView.This work pioneers melt electrowriting (MEW) of polyethylene vinyl acetate (PEVA) to fabricate ultra‐compliant, high‐resolution scaffolds. By integrating microscale precision with soft tissue‐like biomechanics, PEVA overcomes stiffness‐driven limitations of conventional MEW polymers, establishing a mechanically biomimetic platform for soft tissue ...

Factoring multivariate integral polynomials [PDF]
Theoretical Computer Science, 1984 AbstractWe present an algorithm to factorize polynomials in several variables with integral coefficients that is polynomial-time in the degrees of the polynomial to be factored, for any fixed number of variables. Our algorithm generalizes the algorithm presented by Lenstra, Lenstra Jr. and Lovász (1982) to factorize integral polynomials in one variable.

Advanced Healthcare Materials, EarlyView.A two‐phase workflow (OFAT screening followed by central composite design) maps how processing variables tune PFCE‐PLGA nanoparticle size, dispersity, surface charge, loading, and 19F‐MRI signal. In situ, time‐resolved synchrotron SAXS tracks albumin‐corona growth on intact dispersions and reveals PFCE‐dependent adsorption pathways.
