Orientable quadratic equations in free metabelian groups [PDF]
arXiv, 2018 We prove that the Diophantine problem for orientable quadratic equations in free metabelian groups is decidable and furthermore, NP-complete. In the case when the number of variables in the equation is bounded, the problem is decidable in polynomial time.

Reprogrammable Mechanical Metamaterials via Passive and Active Magnetic Interactions
Advanced Materials, EarlyView.The combination of flexible matrices with embedded hard‐magnetic nodes enables metastructures with reprogrammable mechanical properties, even in the absence of external magnetic fields. The evolving interaction between nodes during structural deformation allows mechanical tunability under quasi‐static and dynamic loading, and bistable transitions. This

Stability for the Mixed Type of Quartic and Quadratic Functional Equations
Journal of Function Spaces, 2014 We establish the general solutions of the following mixed type of quartic and quadratic functional equation: f(2x+y)+f(2x-y)=4f(x+y)+4f(x-y)+2f(2x)-8f(x)-6f(y).

Cardiac Organoid Model Inspired Micro‐Robot Smart Patch to Treat Myocardial Infarction
Advanced Materials, EarlyView.The heart organoid model exhibits the acidic microenvironment characteristic of myocardial infarction, which emerges as a pivotal force propelling the movement of micro‐robots. These micro‐robots, administered through microneedles, can penetrate deep into the tissue, effectively delivering therapeutic payloads to facilitate heart repair.

Positive solutions of a quadratic integro-differential equation
Journal of the Egyptian Mathematical Society, 2014 In this paper, we study the existence of at least one positive and nondecreasing solution for the initial value problem of a quadratic integro-differential equation by applying the technique of measure of noncompactness. Some examples will be included to
