Comparing the Effects of Chemical Optical Clearing Agents and Mechanical Compression on the Optical Attenuation of Porcine Skin

open access: yesJournal of Biophotonics, Volume 19, Issue 7, July 2026.
Quantitative SD‐OCT analysis reveals that topically applied chemical optical clearing agents, specifically PEG‐400 combined with oleic acid and aqueous tartrazine, significantly reduce the skin optical attenuation coefficient. In contrast, mechanical compression proved ineffective, identifying chemical clearing as a superior strategy for optimizing ...

Observation‐Constrained Fossil Fuel CO2 Emissions Reveal Post‐2018 Stabilization in China

open access: yesGeophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract Accurate quantification of interannual variations in China's fossil fuel CO2 (FFCO2) emissions is critical for climate policy evaluation. However, bottom‐up inventories exhibit growing discrepancies. Here, we estimate China's 2015–2023 FFCO2 emissions using the Regional multi‐Air Pollutant Assimilation System, integrating in situ observations ...

Upper and lower bounds of the AA-Berezin number of operators

open access: yesTURKISH JOURNAL OF MATHEMATICS, 2021
Summary: Let \(A\) be a positive bounded linear operator acting on a complex Hilbert space \(\mathcal{H}\). Any positive operator \(A\) induces a semiinner product on \(\mathcal{H}\) defined by \(\langle x, y\rangle_A:= \langle Ax, y\rangle_{\mathcal{H}}\), \(\forall x, y\in\mathcal{H}\).

On the Berezin symbol [PDF]

open access: yes, 1994
Let ${\cal H}$ be a functional Hilbert space of analytic functions on a complex domain $\Omega,$ with the normalized reproducing kernel function $k\sb{z},\ z\in\Omega.$ If A is a linear map of ${\cal H}$ into itself, the Berezin symbol, A, of A is ...

A Method for Weight Multiplicity Computation Based on Berezin Quantization

open access: yesSymmetry, Integrability and Geometry: Methods and Applications, 2009
Let G be a compact semisimple Lie group and T be a maximal torus of G. We describe a method for weight multiplicity computation in unitary irreducible representations of G, based on the theory of Berezin quantization on G/T.

From Populism to Fascism? On Our Present‐Time Political Categories

open access: yesSociology Lens, Volume 39, Issue 2, Page 240-248, June 2026.
ABSTRACT With the global rise of far‐right governments, two categories are available to describe this aspect of our current times: populism and fascism. This raises a twofold question: analytically, which is the most accurate to describe these authoritarian governments?

New Approach to Generalized Berezin Norms and Rigorous Operator Bounds

open access: yesMathematics
Let HΘ,⟨·,·⟩ be a reproducing kernel Hilbert space over a non-empty set Θ, and let A be a non-zero positive operator on HΘ. This operator induces a semi-inner product given by ⟨ξ,η⟩A=⟨Aξ,η⟩ for all ξ,η∈HΘ, with the associated seminorm ∥ξ∥A=⟨ξ,ξ⟩A.

Detection and Quantification of Dysprosium in Plant Tissues

open access: yesPlant Direct, Volume 10, Issue 4, April 2026.
ABSTRACT The growing demand for rare‐earth elements (REEs), particularly dysprosium (Dy), underscores the need for sustainable extraction methods. Recovery of Dy, particularly from geographically distributed waste sources, is challenging. This gap positions phytomining, a technique using plants to accumulate metals, as a promising alternative. However,

Semiclassical inequalities for Dirichlet and Neumann Laplacians on convex domains

open access: yesCommunications on Pure and Applied Mathematics, Volume 79, Issue 3, Page 762-822, March 2026.
Abstract We are interested in inequalities that bound the Riesz means of the eigenvalues of the Dirichlet and Neumann Laplacians in terms of their semiclassical counterpart. We show that the classical inequalities of Berezin–Li–Yau and Kröger, valid for Riesz exponents γ≥1$\gamma \ge 1$, extend to certain values γ<1$\gamma <1$, provided the underlying ...
