Müntz linear transforms of Brownian motion [PDF]

, 2014
We consider a class of Volterra linear transforms of Brownian motion associated to a sequence of Müntz Gaussian spaces and determine explicitly their kernels; the kernels take a simple form when expressed in terms of Müntz-Legendre polynomials. These are

All‐in‐One Analog AI Hardware: On‐Chip Training and Inference with Conductive‐Metal‐Oxide/HfOx ReRAM Devices

Advanced Functional Materials, EarlyView.
An all‐in‐one analog AI accelerator is presented, enabling on‐chip training, weight retention, and long‐term inference acceleration. It leverages a BEOL‐integrated CMO/HfOx ReRAM array with low‐voltage operation (<1.5 V), multi‐bit capability over 32 states, low programming noise (10 nS), and near‐ideal weight transfer.

Linear filtering with fractional Brownian motion in the signal and observation processes [PDF]

, 1999
Integral equations for the mean-square estimate are obtained for the linear filtering problem, in which the noise generating the signal is a fractional Brownian motion with Hurst index h∈(3/4,1) and the noise in the observation process includes a ...

Anti‐Inflammatory and Neuroactive Effects of Polymer‐Coated Iron Oxide Nanoparticles Functionalized With Interleukin 4 for Spinal Cord Injury

Advanced Healthcare Materials, EarlyView.
Polymer‐coated IONPs functionalized with IL‐4 display respective neuroactive and anti‐inflammatory actions on neural progenitor cells and macrophages/microglia in vitro. When examined chronically in a rat experimental model of spinal cord injury, rGO scaffolds carrying these nanosystems adequately integrate into the lesion, significantly reduce ...

Linear growth of circuit complexity from Brownian dynamics

Journal of High Energy Physics, 2023
How rapidly can a many-body quantum system generate randomness? Using path integral methods, we demonstrate that Brownian quantum systems have circuit complexity that grows linearly with time.

Interface Dynamics in Biomolecular Condensates by High‐Speed AFM

Advanced Materials Interfaces, EarlyView.
High‐speed atomic force microscopy provides nanoscale structural dynamics at the liquid interface of biomolecular condensates, key elements in several cellular pathways. By addressing the challenges of low surface tension and condensate‐induced instabilities, we achieve nanometer spatial and sub‐second temporal resolution, revealing structural ...

Hausdorff measure of arcs and Brownian motion on Brownian spatial trees [PDF]

, 2009
A Brownian spatial tree is defined to be a pair $(\mathcal{T},\phi)$, where $\mathcal{T}$ is the rooted real tree naturally associated with a Brownian excursion and φ is a random continuous function from $\mathcal{T}$ into ℝd such that, conditional on ...

Information Transmission Strategies for Self‐Organized Robotic Aggregation

Advanced Robotics Research, EarlyView.
In this review, we discuss how information transmission influences the neighbor‐based self‐organized aggregation of swarm robots. We focus specifically on local interactions regarding information transfer and categorize previous studies based on the functions of the information exchanged.
