Luxemburg Norm Characterizations of BLO Spaces in General Metric Measure Frameworks

Mathematics
This study provides new equivalent descriptions of the Bounded Lower Oscillation (BLO) space through Luxemburg-type Lφ integrability conditions, where φ is a nonnegative function with either convexity or concavity.

Log-Concavity and the Exponential Formula

Journal of Combinatorial Theory, Series A, 1999
\textit{E. A. Bender} and \textit{E. R. Canfield} [J. Comb. Theory, Ser. A 74, No. 1, 57-70, Art. No. 0037 (1996; Zbl 0853.05013)] showed that passing a log-concave sequence through the exponential formula results in a log-concave sequence that is almost log-convex.

Does Palsa Thaw in Northern Finland Contribute to Remobilisation of Metals Accumulated in Peat Into Surface Waters?

Land Degradation &Development, EarlyView.
ABSTRACT Permafrost is rapidly degrading in the sporadic zone, including palsa mires in Scandinavia. Peatlands in the area have likely accumulated heavy metals from atmospheric deposition of industrial contaminants in the wider region. As the palsa mire chemical composition is not well known, and in other permafrost regions the permafrost thaw may ...

An Alternative Type II Claims Pareto Model for Reliability and Bimodal Risk Analysis: Copulas, Properties, Mathematical Modeling, and Actuarial Case Study

Journal of Mathematics
This article aims to present a new type-II claims Pareto extension for statistical reliability and actuarial analysis. The new probabilistic density can be simplified in terms of the baseline densities.

Applicability of the steady‐state oxygen stable isotope method for estimating metabolism in low‐productivity Arctic lakes

Limnology and Oceanography: Methods, EarlyView.
Abstract Metabolism is a key property of lake ecosystem functioning, but logistical challenges make it difficult to estimate across remote regions. The steady‐state dissolved oxygen (DO) stable isotope method (18O method) estimates metabolism from discrete water samples and thus enables large‐scale surveys.

Dual curvature measures for $\log$-concave functions

Journal of Differential Geometry
We introduce dual curvature measures for log-concave functions, which in the case of characteristic functions recover the dual curvature measures for convex bodies introduced by Huang-Lutwak-Yang-Zhang in 2016. Variational formulas are shown. The associated Minkowski problem for these dual curvature measures is considered and sufficient conditions in ...

Weak Solutions for a Class of Nonlocal Singular Problems Over the Nehari Manifold

Mathematical Methods in the Applied Sciences, EarlyView.
ABSTRACT In this paper, we consider a nonlocal model of dilatant non‐Newtonian fluid with a Dirichlet boundary condition. By using the Nehari manifold and fibering map methods, we obtain the existence of at least two weak solutions, with sign information.

Reconciling fractional entropy and black hole entropy compositions

European Physical Journal C: Particles and Fields
This study investigates the implications of adopting fractional entropy in the area law framework and demonstrates its natural alignment with an isothermal description of black hole composition.
