, 2008 By absolute factorization we mean the factorization of a multivariate polynomial over the complex numbers. This notion of factorization is closest to the geometry and allows for approximate input coefficients. In this note, we mainly follow [4].

A Simple Near-Optimal Subdivision Algorithm for Complex Root Isolation based on the Pellet Test and Newton Iteration [PDF]
, 2016 We describe a subdivision algorithm for isolating the complex roots of a polynomial $F\in\mathbb{C}[x]$. Our model assumes that each coefficient of $F$ has an oracle to return an approximation to any absolute error bound.

Absolute stability of systems with multiple non-linearities
, 1968 A frequency-domain criterion for the asymptotic stability-in-the-large of systems containing many non-linearities is derived in terms of the positive realness of the product of a diagonal multiplier matrix and the transfer function matrix of the linear ...

High Tree Species Diversity Promotes Thermal Enhancement Response of Microbial Carbon Use Efficiency
Advanced Science, EarlyView.ABSTRACT Predicting soil carbon dynamics under warming is constrained by limited understanding of microbial thermal adaptation, particularly whether microbial carbon use efficiency (CUE) can adapt to warming and how plant diversity modulates this response. Using soils from a natural tree species diversity gradient in a subtropical forest, we combined a

Advanced Science, EarlyView.A fully soft, self‐reconfigurable gripper inspired by rapeseed flowers is monolithically 3D‐printed and electronics‐free, switching between diagonal and parallel finger arrangements. Establishing a self‐reconfigurable grasping paradigm, the gripper enables diverse manipulation tasks, including rotating bulbs, picking fruits, grasping cross‐scale ...

Exact methods for comparison of estimation strategies in survey sampling.
, 2010 PhDMany strategies in survey sampling depend on large sample approximation formulae for design-based inference on finite population parameters, which are not valid for small samples. We develop an approach using matrix algebra to tackle many problems
