ChemCatChem, Volume 18, Issue 18, 28 September 2026.In the acidity characterization of zeolites by isopropylamine temperature‐programmed desorption (IPAm‐TPD), zinc altered the reaction pathways of isopropylamine. When examined against the quantitative results of other adsorption‐based acidity characterization methods, the IPAm‐TPD results still appeared representative of acidic properties, when the ...

Nonstandard Analysis Applied to Advanced Undergraduate Mathematics - Infinitesimal Modeling
, 2003 This is a Research and Instructional Development Project from the U. S. Naval Academy. In this monograph, the basic methods of nonstandard analysis for n-dimensional Euclidean spaces are presented. Specific rules are deveoped and these methods and rules are applied to rigorous integral and differential modeling.

Short‐Term CO 2$$ {}_2 $$ Emissions Forecasting: Insight From the Italian Electricity Market
Environmetrics, Volume 37, Issue 6, September 2026.ABSTRACT This study investigates the short‐term forecasting of carbon emissions from electricity generation in the Italian power market. Using hourly data from 2021 to 2023, several statistical models and forecast combination methods are evaluated and compared at the national and zonal levels.

Bitlis Eren Üniversitesi Fen Bilimleri DergisiThis paper presents a mathematical model describing climate change in the oxygen-plankton system. The model consists of a system of non-linear ordinary differential equations. The Nonstandard Finite Difference (NSFD) method is applied to discretize the non-linear system.

Interdisciplinary Materials, Volume 5, Issue 5, Page 834-867, September 2026.Vibrations in matter, from spider webs to molecules, water to flames, share a grammar with music. We propose that creativity emerges when constraints force expansion beyond existing possibilities. Selective imperfection restores balance, enabling invention.

Nonstandard Foundations of Equilibrium Search Models [PDF]
We develop an equilibrium sequential search model which includes most of the literature as special cases. In particular, the model can accommodate heterogeneity in buyers’ search costs and demand functions and firms’ cost functions, with general demand ...

Signed Projective Cubes, a Homomorphism Point of View
Journal of Graph Theory, Volume 113, Issue 1, Page 38-56, September 2026.ABSTRACT The (signed) projective cubes, as a special class of graphs closely related to the hypercubes, are on the crossroad of geometry, algebra, discrete mathematics and linear algebra. Defined as Cayley graphs on binary groups, they represent basic linear dependencies.
