An Activity‐Based Inversion Framework for Estimating Sectoral Anthropogenic CO2 Emissions Using Multi‐Pollutant Satellite Observations

Geophysical Research Letters, Volume 53, Issue 17, 16 September 2026.
Abstract This study develops an activity‐based inversion framework to quantify sectoral carbon dioxide (CO2) emissions using observations of co‐emitted air pollutants. It leverages distinct sectoral co‐emission profiles of nitrogen oxides (NOx), sulfur dioxide (SO2), and carbon monoxide (CO) to attribute sources and optimize sectoral activity‐rate ...

Numerical radius and Berezin number inequality

Journal of Mathematical Analysis and Applications, 2023
We study various inequalities for numerical radius and Berezin number of a bounded linear operator on a Hilbert space. It is proved that the numerical radius of a pure two-isometry is 1 and the Crawford number of a pure two-isometry is 0. In particular, we show that for any scalar-valuednon-constant inner function $θ$, the numerical radius and the ...

The weighted Davis-Wielandt Berezin number for reproducing kernel Hilbert space operators

Journal of Inequalities and Applications
A functional Hilbert space is the Hilbert space of complex-valued functions on some set Θ ⊆ C $\Theta \subseteq \mathcal {C}$ that the evaluation functionals φ λ ( f ) = f ( λ ) $\varphi _{\lambda}\left ( f\right ) =f\left ( \lambda \right ) $ , λ ∈ Θ ...

A new mean-Berezin norm for operators in reproducing kernel Hilbert spaces

Journal of Inequalities and Applications
A functional Hilbert space is defined as the Hilbert space K $\mathcal{K}$ of complex-valued functions defined on a set Θ. In this space, the evaluation functionals ψ ε ( h ) = h ( ε ) $\psi _{\varepsilon}(h) = h(\varepsilon )$ , for ε ∈ Θ $\varepsilon ...

‘The big chunky belemnite’: a new relict megateuthidid from the Oxfordian (Late Jurassic) of Wyoming, USA, and its place in the evolutionary history of the group

Papers in Palaeontology, Volume 12, Issue 5, September/October 2026.
Abstract We describe and discuss two finds of large and untypical belemnite rostra originating from the upper part of the Sundance Formation (Oxfordian) of Wyoming, USA. With a diameter reaching c. 60 mm at the anterior end, these rostra are the thickest known for belemnites so far.

Environmental Release of Genetically Intervened Microorganisms: Towards a New Narrative

Microbial Biotechnology, Volume 19, Issue 9, September 2026.
From control to partnership: Rethinking the environmental release of laboratory‐trained microorganisms for bioremediation. ABSTRACT The deliberate release of genetically engineered microorganisms for environmental applications has remained largely blocked since the early days of recombinant DNA technology, when limited ecological knowledge, lack of ...

Generalized loss of trust following political betrayal: Cross‐country evidence in the context of elections

Political Psychology, Volume 47, Issue 4, August 2026.
Abstract This research investigates how perceptions of political betrayal—that is, the perceived violation of mutually known pivotal expectations by a political entity—shape political trust. We test a generalization hypothesis that the loss of trust might extend beyond the specific political entity (i.e., the one who betrayed) and generalize to others.

Crimean‐Congo Haemorrhagic Fever Virus Exposure in Horses and Donkeys in Border Livestock Markets of Nigeria

Zoonoses and Public Health, Volume 73, Issue 5, Page 422-430, August 2026.
ABSTRACT Introduction Crimean‐Congo haemorrhagic fever virus (CCHFV) is a tick‐borne zoonotic pathogen of major public health importance in Africa. Although CCHFV exposure has been reported in several livestock species in Nigeria, data on equids remain limited despite their extensive involvement in livestock movement and trade.

Parallelism and Rigorous Bounds for the $\mathbb{A}$-Normalized Davis–Wielandt Berezin Number

Mathematics
In this paper, we introduce and study the A-normalized Davis–Wielandt Berezin number for bounded linear operators on a reproducing kernel Hilbert space. Suppose that the space is equipped with a positive semi-inner product induced by a non-zero positive ...
