Noncolliding Squared Bessel Processes

, 2011
We consider a particle system of the squared Bessel processes with index $\nu > -1$ conditioned never to collide with each other, in which if $-1 < \nu < 0$ the origin is assumed to be reflecting.

A Dynamic Spike Sorter for Multiscale Nanoelectrode Array Recordings

Advanced Materials Interfaces, EarlyView.
This work introduces a dynamic spike sorting pipeline that isolates diverse electrical signals from nanoelectrode arrays. Using biophysical simulations to calibrate signal processing, the approach reveals relationships between action potentials and membrane fluctuations, advancing the understanding of neuronal network excitability.

Comparative analysis of formulations for crossed artifact elimination in the frequency–Bessel spectrograms

Frontiers in Earth Science
The frequency–Bessel transformation method has significantly advanced the extraction of multimodal surface waves in seismic research. However, the presence of crossed artifacts in frequency–Bessel spectrograms, particularly when stations are regularly ...

Vibration damping in road bridges – two case studies of full scale experiments [PDF]

MATEC Web of Conferences, 2019
The paper presents the results of a vibration damping analysis of two road viaducts. The analysis was based on displacement signals recorded during the dynamic load tests carried out before an acceptance process of the viaducts.

How to Manufacture Photonic Metamaterials

Advanced Materials Technologies, EarlyView.
Metamaterials boast applications such as invisibility and “hyperlenses” with resolution beyond the diffraction limit, but these applications haven’t been exploited in earnest and the market for them hasn’t grown much likely because facile and economical methods for fabricating them without defect has not emerged.

The Log-Asset Dynamic with Euler–Maruyama Scheme under Wishart Processes

International Journal of Mathematics and Mathematical Sciences, 2021
This article deals with Wishart process which is defined as matrix generalization of a squared Bessel process. We consider a single risky asset pricing model whose volatility is described by Wishart affine diffusion processes.

Fiber Bragg Gratings with Micro‐Engineered Temperature Coefficients

Advanced Optical Materials, Volume 13, Issue 8, March 13, 2025.
Fiber Bragg gratings (FBGs) are intrinsically responsive to temperature and strain simultaneously. In this research, low‐loss FBGs with micro‐engineered temperature coefficients are fabricated, utilizing refractive index liquid‐filled microchannels in the cladding.

Spin‐Orbit Photonics with Potato Starch Lenses

Advanced Optical Materials, EarlyView.
Native potato starch spherulites are introduced as volumetric optical elements that modulate both dynamic and geometric phases of light. These spherulites focus light and generate optical vortices via spin‐orbit interaction, functioning as polarization‐sensitive microlenses. Their unique radial anisotropy enables applications in vortex beam generation,

Excitation‐Wavelength‐Tunable Lasing in Individual Quantum Dot Superparticles

Advanced Optical Materials, EarlyView.
Mesoscale superparticles assembled from CdSe quantum dots are shown to behave as microlasers with emission properties that can be tuned by changing the excitation wavelength. Abstract Microcavities enable precise control over light‐matter interactions, supporting a wide range of applications in photonics and optoelectronics.
