Analysis of the experimental absorption spectrum of the rabbit lung and identification of its components

Journal of Biophotonics, Volume 18, Issue 12, December 2025.
The broadband absorption coefficient spectrum of the rabbit lung was reconstructed from the absorption spectra of tissue components. The similar accumulation of melanin and lipofuscin was retrieved from the broadband baseline in the absorption coefficient spectrum, and the calculation of the absorption fold ratios for proteins, DNA and hemoglobin ...

Scattering of phonons on two-level systems in disordered crystals

, 2008
We calculate the scattering rates of phonons on two-level systems in disordered trigonal and hexagonal crystals. We apply a model in which the two-level system, characterized by a direction in space, is coupled to the strain field of the phonon via a ...

Estimation of Scattering Properties Modifications Caused by In Vivo Human Skin Optical Clearing Using Line‐Field Confocal Optical Coherence Tomography

Journal of Biophotonics, Volume 18, Issue 12, December 2025.
Line‐field confocal optical coherence tomography (LC‐OCT) is used to determine the human skin in vivo optical properties (OPs) modifications caused by biocompatible optical clearing. After a prior calibration using a phantom with determined OPs, a theoretical model is applied to mean in‐depth intensity profiles of 3D LC‐OCT images acquired during ...

1275‐nm Photobiomodulation Alleviates Brain Drainage Impairment as a Promising Therapeutic Strategy for Aging‐Related Neurological Decline

Aging Cell, Volume 24, Issue 12, December 2025.
Noninvasive 1275‐nm photobiomodulation improves brain drainage and promotes lymphatic clearance of advanced glycation end products (AGEs) in an aging model (AM) in male mice. These effects are associated with nitric oxide release‐mediated dilation of meningeal lymphatic vessels (MLVs).

Topological phase structures of conical refraction beams: expanding orbital angular momentum applications for nanoscale biosensing

Nanophotonics, Volume 14, Issue 24, Page 4447-4457, December 2025.
Abstract Topologically structured light carrying orbital angular momentum (OAM) has emerged as a powerful tool for nano‐photonics and biomedical optics, yet conventional integer‐charge Laguerre–Gaussian (LG) beams suffer from rotational degeneracy that limits diagnostic precision.

Detecting synchronization of self-sustained oscillators by external driving with varying frequency

, 2006
We propose a method for detecting the presence of synchronization of self-sustained oscillator by external driving with linearly varying frequency. The method is based on a continuous wavelet transform of the signals of self-sustained oscillator and ...

HEteronuclear Referencing for METRologic Isotope Calibration (HERMETRIC)

Magnetic Resonance in Chemistry, Volume 63, Issue 11, Page 885-894, November 2025.
The graphical abstract shows a steelyard balance with the counter weight indicating the amount of deuterium as internal standard defined through D2O addition. The bowl of smarties represents the variety of NMR nuclei this principle was and can be applied to.
