Permanents of doubly stochastic matrices
Discrete Mathematics, 1986 Let \(\mu_ k(n)\) denote the minimum value of the permanent of all \(n\times n\) (0,1) matrices whose row and column sums equal k. It has been conjectured that \[ \lim_{n\to \infty}[\mu_ k(n)]^{1/n}=(k-1)^{k- 1}/k^{k-2}. \] The author shows that if \(\prod^{n}_{j=1}\sum^{n}_{i=1}a_{ij}\prod_{k\neq 1}(1- a_{kj})\leq per A\) for any \(n\times n\) doubly ...

Disturb‐Resilient and Wake‐up‐Free 2T‐MFMFET Array for Storage and Computing Applications
Advanced Materials Technologies, EarlyView.A disturb‐resilient and wake‐up‐free 2T‐MFMFET array fabricated using a FeRAM‐compatible process demonstrates excellent uniformity, a large memory window, and 3‐bit multi‐level‐cell storage capability. A newly proposed hybrid in‐memory computing scheme further enables accurate multiply–accumulate operations with minimal refresh overhead, highlighting ...

Rotating Fluorescent Nanodiamond Assemblies With Focused Laguerre–Gaussian Beams
Advanced Optical Materials, EarlyView.Self‐assembled fluorescent nanodiamond clusters are optically trapped and driven into controlled two‐dimensional rotation with Laguerre–Gaussian beams. With localized optical excitation, optically detected magnetic resonance spectra are collected at defined points along the orbit in a uniform external magnetic field.

Rotational Representations of Stochastic Matrices
The Annals of Probability, 1985 Let \(P=(p_{ij})\) be an \(n\times n\) stochastic matrix with a positive stationary row eigenvector \(\pi =(\pi_ 1,\pi_ 2,...,\pi_ n)\). Let J be a partition of the unit circle into sets \(J_ 1,J_ 2,...,J_ n\) with \(m(J_ i)=\pi_ i\), where m is the Lebesgue measure. Let \(f_ t(x)\) indicate a rotation through distance t. It has been shown that for any

Consensus Formation and Change are Enhanced by Neutrality
Advanced Science, EarlyView.Neutral agents are shown to enhance both the formation and overturning of consensus in collective decision‐making. A general mathematical model and experiments with locusts and humans reveal that neutrality enables robust consensus via simple interactions and accelerates consensus change by reducing effective population size.
