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

Sociology 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?

Detection and Quantification of Dysprosium in Plant Tissues

Plant 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

Communications 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 ...

A Method for Weight Multiplicity Computation Based on Berezin Quantization

Symmetry, 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.

Participation Beyond Compliance: Who Tried to Influence Other People's Vaccination Behaviour During the COVID‐19 Crisis?

Sociology of Health &Illness, Volume 48, Issue 3, March 2026.
ABSTRACT In this paper, we call for more attention to be paid to what we call ordinary contributions to public health policies: the propensity of ordinary citizens to actively influence others to follow or reject a health policy. Shifting the focus from personal compliance to active participation (i.e., ordinary contribution) raises distinct questions ...

New Approach to Generalized Berezin Norms and Rigorous Operator Bounds

Mathematics
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.

Universality for fluctuations of counting statistics of random normal matrices

Journal of the London Mathematical Society, Volume 113, Issue 2, February 2026.
Abstract We consider the fluctuations of the number of eigenvalues of n×n$n\times n$ random normal matrices depending on a potential Q$Q$ in a given set A$A$. The eigenvalues of random normal matrices are known to form a determinantal point process, and are known to accumulate on a compact set called the droplet under mild conditions on Q$Q$. When A$A$

Improved inequalities for the Berezin number

Journal of Mathematical Inequalities
Summary: A functional Hilbert space is the Hilbert space of complex-valued functions on some set \(\Theta\subseteq\mathbb{C}\) that the evaluation functionals \(\varphi_\tau(f) = f(\tau)\), \(\tau\in\Theta\) are continuous on \(\mathscr{H}\). The Berezin number (radius) of an operator \(T\) is defined by \(\mathbf{ber}(T) = \sup\limits_{\tau\in\Theta}|\

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

TURKISH 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 \(\langle x, y\rangle_A:= \langle Ax, y\rangle_{\mathcal{H}}\), \(\forall x, y\in\mathcal{H}\).

Protective Role of Physical Exercise and Exercise‐Induced FNDC5/Irisin in Combating Diabetes‐Related Cognitive Impairment and Autonomic and Peripheral Neuropathies: A Comprehensive Review

Journal of Diabetes Research, Volume 2026, Issue 1, 2026.
The rising prevalence of diabetes has been closely linked to increased mortality and morbidity, particularly as its complications become more widespread. Among the most challenging of these complications are cognitive impairments and diabetic neuropathies, which are neurodegenerative conditions that significantly diminish the quality of life in the ...
