Nonergodic subdiffusion from Brownian motion in an inhomogeneous medium. [PDF]

open access: yesPhysical Review Letters, 2014
Nonergodicity observed in single-particle tracking experiments is usually modeled by transient trapping rather than spatial disorder. We introduce models of a particle diffusing in a medium consisting of regions with random sizes and random diffusivities.

On bifractional Brownian motion [PDF]

open access: yesStochastic Processes and their Applications, 2006
AbstractThis paper is devoted to analyzing several properties of the bifractional Brownian motion introduced by Houdré and Villa. This process is a self-similar Gaussian process depending on two parameters H and K and it constitutes a natural generalization of fractional Brownian motion (which is obtained for K=1).

The State of High‐Resolution Imaging of the Human Inner Ear: A Look Into the Black Box

open access: yesAdvanced Science, EarlyView.
High‐resolution imaging of the cochlea is challenged by numerous unique aspects of this organ, where sensorineural cells, crucial for hearing, are too small for conventional modalities like magnetic resonance imaging and computed tomography. This article reviews current imaging techniques, emerging technologies, and innovations aimed at improving ...

Noncovalent Synthesis of Topological Heterostructures Using a Site‐Selective Electrostatic Co‐Assembly Strategy

open access: yesAngewandte Chemie, EarlyView.
A site‐selective electrostatic co‐assembly (SSECA) strategy was developed to fabricate a variety of topological heterostructures (THSs) with unprecedented architectures from two‐component systems of organometallic complexes and block copolymers. The THSs are composed of rigid parts of closely stacked organometallic complexes and flexible segments ...

A Spurious Brownian Motion [PDF]

open access: yesProceedings of the American Mathematical Society, 1985
There exists an R d {{\mathbf {R}}^d} -valued mean-zero Gaussian process, all of whose projections agree with the projections of standard Brownian motion, yet which is not standard Brownian motion.

Self‐Propelled In Situ Polymerized Nanoparticles Activating the STING Pathway for Enhanced Bladder Cancer Immunotherapy

open access: yesAdvanced Science, EarlyView.
A self‐propelled nanomedicine delivery system forms DMCU nanoparticles in the bladder via in situ polymerization of dopamine hydrochloride, Mn2+, cGAMP, and urease. The urease‐driven propulsion enhances retention and drug delivery. These nanoparticles activate the STING pathway, stimulating dendritic cells and T cells to boost anti‐bladder cancer ...

Vibronic Trimer Design Enhancing Intramolecular Triplet‐Exciton Hopping to Accelerate Triplet‐Triplet Annihilation for Photon Upconversion

open access: yesAngewandte Chemie, EarlyView.
Triplet‐triplet annihilation‐based photon up‐conversion (TTA‐UC) system using an anthracene‐based UC emission by assembling multiple chromophores linked to a boron to enhance TTA rate constant. Structural fluctuations driven by vibronic motion induce picosecond intramolecular triplet exciton hopping, expanding the triplet exciton distribution and ...

Spinning Brownian motion

open access: yesStochastic Processes and their Applications, 2015
We prove strong existence and uniqueness for a reflection process $X$ in a smooth, bounded domain $D$ that behaves like obliquely-reflected-Brownian-motion, except that the direction of reflection depends on a (spin) parameter $S$, which only changes when $X$ is on the boundary of $D$ according to a physical rule.

Revealing Dynamic Ion Transport in Tailorable Carbon Nano‐Skyscraper Electrodes

open access: yesAdvanced Science, EarlyView.
A 3D carbon nanotube electrode reveals how ions and electrons prioritize rapid transport over the shortest paths during charging. By creating a uniformly interconnected porous network, researchers improved electrode efficiency, surpassing traditional localized and gradient designs.

A companion to the preclinical common data elements and case report forms for in vivo rodent neuroimaging: A report of the TASK3‐WG3 Neuroimaging Working Group of the ILAE/AES Joint Translational Task Force

open access: yesEpilepsia Open, EarlyView., 2022
Abstract The International League Against Epilepsy/American Epilepsy Society (ILAE/AES) Joint Translational Task Force established the TASK3 working groups to create common data elements (CDEs) for various aspects of preclinical epilepsy research studies, which could help improve the standardization of experimental designs.
