Transition density of a hyperbolic Bessel process
, 2016 We investigate the transition density of a hyperbolic Bessel process for integer dimensions and show a link between transition densities of a hyperbolic Brownian motion and a Bessel process in the same dimension. Using the so-called Millson’s formula for

The generating function for the Bessel point process and a system of coupled Painlevé V equations [PDF]
Random Matrices. Theory and Applications, 2017 We study the joint probability generating function for [Formula: see text] occupancy numbers on disjoint intervals in the Bessel point process. This generating function can be expressed as a Fredholm determinant.

Nano-jet related to Bessel beams and to super-resolutions in microsphere optical experiments
EPJ Techniques and Instrumentation, 2017 The appearance of a Nano-jet in the microsphere optical experiments is analyzed by relating this effect to non-diffracting Bessel beams. By inserting a circular aperture with a radius of subwavelength dimension in the EM waist, and sending the ...

GeAl2‐2xFe2xO3(OH)4 Nanotubes: New Electrocatalyst for Oxygen Evolution Reaction
Advanced Functional Materials, EarlyView.Fe‐doped imogolite nanotubes are synthesized via a one‐step hydrothermal method with varying Fe substitution ratios x. Structural and spectroscopic analyses confirm homogeneous Fe incorporation while preserving tubular shape. Optimal doping at x = 0.05 enhances optical absorption, narrows band gap, reduces charge transfer resistance, and significantly ...

Peptide Sequencing With Single Acid Resolution Using a Sub‐Nanometer Diameter Pore
Advanced Functional Materials, EarlyView.To sequence a single molecule of Aβ1−42–sodium dodecyl sulfate (SDS), the aggregate is forced through a sub‐nanopore 0.4 nm in diameter spanning a 4.0 nm thick membrane. The figure is a visual molecular dynamics (VMD) snapshot depicting the translocation of Aβ1−42–SDS through the pore; only the peptide, the SDS, the Na+ (yellow/green) and Cl− (cyan ...

Dynamics of Twisted Electron Impact Ionization of CH4 and NH3 Molecule
Atoms, 2023 Electron vortex beams (EVBs, also known as twisted electron beams) possess an intrinsic orbital angular momentum (OAM) with respect to their propagation direction.

Stopping Times of Bessel Processes
The Annals of Probability, 1987 Let \(X^ x_{\alpha}\) be a Bessel process with parameter \(\alpha\), starting at \(x\geq 0\). \textit{L. Gordon} [Ann. Math. Stat. 43, 1927-1934 (1972; Zbl 0267.60046)] obtained \(L^ p\) inequalities which relate stopping times to stopping places for the case \(\alpha =1\), \(x=0\) and \(p>\). \textit{W. A. Rosenkrantz} and \textit{S.

Advanced Functional Materials, EarlyView.A spatiotemporal plasma–mediated laser processing approach is developed to fabricate ultrahigh–aspect ratio nanochannel arrays and corresponding perovskite nanowire arrays within transparent materials for optoelectronics devices. The laser‐fabricated nanochannels serve as templates for controlled perovskite infiltration and crystallization, enabling ...
