Karhunen-Loève Expansion for the Second Order Detrended Brownian Motion

Abstract and Applied Analysis, 2014
Based on the norm in the Hilbert Space L2[0,1], the second order detrended Brownian motion is defined as the orthogonal component of projection of the standard Brownian motion into the space spanned by nonlinear function subspace.

Evaluation of Cell‐Extracellular Vesicle Interaction Using a Microfluidic Microsystem (CellExoChip)

Advanced Materials Technologies, EarlyView.
A new microfluidic platform, the CellExoChip, reveals how cancer cells interact with exosomes to influence metastasis. This device isolates cancer cells and tracks their uptake exosomes and secretion of their exosomes in response to other exosomes. Lung cancer cells are showed preferentially absorb and respond to their own exosomes—hinting at a hidden ...

Pitman transforms and Brownian motion in the interval viewed as an affine alcove [PDF]

, 2019
Pitman's theorem states that if {Bt, t $\ge$ 0} is a one-dimensional Brownian motion, then {Bt -- 2 inf s$\le$t Bs, t $\ge$ 0} is a three dimensional Bessel process, i.e. a Brownian motion conditioned in Doob sense to remain forever positive.

Co‐Solvent‐Aided Opto‐Thermophoretic Printing of Gold Nanorod Assemblies

Advanced Optical Materials, EarlyView.
A focused laser beam creates a thermal gradient, driving the gold nanorods and polymer coils toward the heated region of the glass substrate, i.e, the laser spot. After the adsorption of the polymer on the gold surface, the nanorods start to assemble onto the surface in a ring‐shaped pattern that grows radially until the beam is turned off.

Interfacial Assembly of Dye‐Doped Microparticles Driven by Combined Optical and Non‐Optical Forces

Advanced Optical Materials, EarlyView.
Optical trapping controls nano‐ and microparticle assembly using various forces, including absorption for photoexcitable resonant molecules. This study demonstrates photoexcitation‐mediated assembly, forming hexagonal‐close‐packed structures at the air/solution interface.

Flow and Heat Transfer to Sisko Nanofluid over a Nonlinear Stretching Sheet.

PLoS ONE, 2015
The two-dimensional boundary layer flow and heat transfer to Sisko nanofluid over a non-linearly stretching sheet is scrutinized in the concerned study. Our nanofluid model incorporates the influences of the thermophoresis and Brownian motion.

Harnessing Ultrafast Optical Pulses for 3D Microfabrication by Selective Tweezing and Immobilization of Colloidal Particles in an Integrated System

Advanced Photonics Research, Volume 6, Issue 5, May 2025.
Microfabrication using nano‐ to micron‐sized blocks has transformative potential for next‐gen electronics, optoelectronics, and materials. Traditional methods are limited by scalability and precision. STIC, a single‐laser system for precise colloid manipulation and immobilization using femtosecond lasers, is introduced that enables efficient 3D ...

Small values and functional laws of the iterated logarithm for operator fractional Brownian motion

Open Mathematics
The multivariate Gaussian random fields with matrix-based scaling laws are widely used for inference in statistics and many applied areas. In such contexts, interests are often Hölder regularities of spatial surfaces in any given direction.

Application of the Fractal Brownian Motion to the Athens Stock Exchange

Fractal and Fractional
The Athens Stock Exchange (ASE) is a dynamic financial market with complex interactions and inherent volatility. Traditional models often fall short in capturing the intricate dependencies and long memory effects observed in real-world financial data. In
