Rotational Representations of Stochastic Matrices

The Annals of Probability, 1983
Let u denote Lebesgue measure on the interval \(X=[0,1)\). A stochastic matrix \(P=(p_{ij})\) is said to have a rotational representation if there exists a nonnegative number t and a partition \(S=\{S_ i\}^ n_{i=1}\) of X into nonempty sets \(S_ i\), which are each finite unions of intervals, such that \(p_{ij}=u(S_ i\cap f^{-1}(S_ j))/u(S_ i),\) 1 ...

Path‐Decoupled Cation‐Eutaxy III–V van der Waals Memristive Semiconductors for Mitigating the Neuromorphic Accuracy‐Energy Trade‐off

Advanced Materials, EarlyView.
Path‐decoupled III–V van der Waals memtransistors spatially separate ionic and electronic transport to overcome the conventional trade‐off between accuracy and energy in neuromorphic hardware. Mobile K+ ions in the vdW gaps set a wide conductance window, Gmax/Gmin, while gate‐tunable hole conduction lowers programming energy, enabling reliable ...

Stochastic modeling of plasmonic field evolution propagating in non-uniform metallic strip arrays

Results in Optics
The amplitude field distribution of surface plasmons propagating in an array of non-uniform metallic strips is analyzed. The study models the evolution of the amplitude function as a Markov chain, which is associated with a stochastic matrix.

Stability criteria on delay-dependent robust stability for uncertain neutral stochastic nonlinear systems with time-delay

Journal of Inequalities and Applications, 2018
This work mainly studies the robust stability analysis and design of a controller for uncertain neutral stochastic nonlinear systems with time-delay. Using a modified Lyapunov–Krasovskii functional and the free-weighting matrices technique, we establish ...

Resolving Heterogeneity of Targeted Lipid Nanoparticles Through Solution‐Based Biophysical Analyses

Advanced Materials, EarlyView.
AF4‐UV‐DLS‐MALS‐SAXS resolves previously inaccessible targeted lipid nanoparticle (tLNP) subpopulations that differ in size, shape, and composition. Correlation of subpopulation‐resolved biophysical properties with in vivo RNA delivery reveals that targeted placental transfection is associated with distinct tLNP subpopulations rather than ensemble ...
