Isoperimetric inequalities on slabs with applications to cubes and Gaussian slabs
Communications on Pure and Applied Mathematics, Volume 79, Issue 4, Page 1012-1072, April 2026.Abstract We study isoperimetric inequalities on “slabs”, namely weighted Riemannian manifolds obtained as the product of the uniform measure on a finite length interval with a codimension‐one base. As our two main applications, we consider the case when the base is the flat torus R2/2Z2$\mathbb {R}^2 / 2 \mathbb {Z}^2$ and the standard Gaussian measure

A Mixture Transition Distribution Modeling for Higher‐Order Circular Markov Processes
Journal of Time Series Analysis, Volume 47, Issue 2, Page 304-320, March 2026.ABSTRACT This study considers the stationary higher‐order Markov process for circular data by employing the mixture transition distribution modeling. The underlying circular transition distribution is based on Wehrly and Johnson's bivariate joint circular models.

Semiparametric regression for circular response with application in ecology
Scandinavian Journal of Statistics, Volume 53, Issue 1, Page 54-101, March 2026.ABSTRACT A regression model for a circular response variable depending on a linear or a circular predictor is presented in this paper. The conditional density belongs to a parametric flexible family that allows for asymmetry and varying peakedness around the modal direction.

Geophysical Research Letters, Volume 53, Issue 3, 16 February 2026.Abstract Turbidity currents are destructive flows that are hazardous to critical seafloor infrastructure on submarine slopes because run‐up heights can be 10–100s of meters, as their relative density is 2–3 orders of magnitude lower than terrestrial flows. Currently, risk analysis is hindered by poor prediction of run‐up heights that are mainly derived

On approximation by trigonometric sums and polynomials [PDF]
Transactions of the American Mathematical Society, 1912 The chief purpose of this paper, carried out in its second part, is the determination of numerical limits for certain constants, hitherto undetermined, which figure in the principal theorems of the first two parts (Abschnitte) of the author's thesis,t concerning the degree of approximation to a given continuous function f (x) that can be attained ...

Ecology and Evolution, Volume 16, Issue 2, February 2026.We combined multiple‐covariate distance sampling (MCDS) with habitat modeling to estimate the abundance and habitat associations of the vulnerable Asian houbara (Chlamydotis macqueenii) in central Iran. Line‐transect surveys in spring 2022 yielded an estimated density of 0.53 individuals/km2 (~5293 birds), with nearly identical results from ...

Neural Network Models for Solar Irradiance Forecasting in Polluted Areas: A Comparative Study
Energy Science &Engineering, Volume 14, Issue 2, Page 935-961, February 2026.Pollution‐aware hybrid ensemble model is proposed to forecast solar irradiance across eight diverse cities. The model integrates MLP, RNN, and NARX to handle varying atmospheric pollution levels. The model outperforms state‐of‐the‐art methods with enhanced accuracy and interpretability on standard solar irradiance data set.

Trigonometric approximation and uniform distribution modulo one [PDF]
Proceedings of the American Mathematical Society, 1988 We construct n n -dimensional versions of the Beurling and Selberg majorizing and minorizing functions and use them to prove results on trigonometric approximation and to prove an n n -dimensional version of the Erdös-Turán inequality. Finally, an application is given to counting solutions of polynomial congruences.
