Compositionally complex doping for zero-strain zero-cobalt layered cathodes

Nature, 2022
The high volatility of the price of cobalt and the geopolitical limitations of cobalt mining have made the elimination of Co a pressing need for the automotive industry1. Owing to their high energy density and low-cost advantages, high-Ni and low-Co or Co-free (zero-Co) layered cathodes have become the most promising cathodes for next-generation ...

Transcoding zeros within complex numerals

Neuropsychologia, 2003
This paper describes a patient (LD) showing a selective syntactic deficit in the production of Arabic numerals. Unlike in previously reported cases, LD's syntactic difficulties result in deletions rather than insertions of zeros, with a reduction of the number magnitude. The pattern of errors highlighted a distinction between "lexical zeros", i.e.

On the Complexity of Polynomial Zeros

SIAM Journal on Computing, 1992
An algorithm for simultaneous approximation of all zeros of a polynomial introduced by Householder is considered. A modification suitable for parallel computation is proposed. The root-finding problem for a polynomial of degree \(n\), having zeros \(z_ i\), \(i=1,\dots,n\) is \(NC\)- reduced to finding a polynomial \(\alpha(z)\) such that \(| \alpha(z_{

Complex Zeros of Algebraic Polynomial with Non-Zero Mean Random Coefficients

Journal of Theoretical Probability, 1999
Let \(a_j\), \(b_j\), \(j=0,\dots,n-1\), be independent normally distributed random variables with a possibly non-zero mean and with a positive variance, and let \(P_n(z)=\sum_{j=0}^{n-1} \eta_jz^j\), \(z\in\Phi\), where \(\eta_j:=a_j+ib_j\) and \(\Phi\) is a compact manifold in the complex plane such that \(0\not\in\Phi\).

Zeros of Complex Polynomials

1993
We consider the complex polynomial p: C → C defined by $$p(z)=\sum\limits_{i=0}^n{{p_i}{z^i}},{p_i}\in\mathbb{C}{\text{, }}i=0, . . . , n, {p_n}\ne 0.$$ (1) (9.1) The Fundamental Theorem of algebra asserts that this polynomial has n zeros counted by multiplicity. Finding these roots is a non trivial problem in numerical mathematics.
