Convolutions with probability densities and applications to PDEs
Electronic Journal of Differential Equations, 2017 In this article we introduce several new convolution operators, generated by some known probability densities. By using the inverse Fourier transform and taking inverse steps (in the analogues of the classical procedures used for example in the heat ...

Mathematical Finance, EarlyView.ABSTRACT Perpetual futures are contracts without expiration date in which the anchoring of the futures price to the spot price is ensured by periodic funding payments from long to short. We derive explicit expressions for the no‐arbitrage price of various perpetual contracts, including linear, inverse, and quantos futures in both discrete and ...

Capital in Motion: Synthesizing the Circulation and Reproduction in a Multi‐Sector Growth Model
Metroeconomica, EarlyView.ABSTRACT This paper analyzes Capital in Motion (CIM) in a capitalist economy, based on Karl Marx's Capital, Volume 2. It examines the circuit of capital, distinguishing between stock and flow variables, and integrates a multi‐sector growth model that combines the circuit and turnover of capital with the reproduction scheme.

The Mathematical History Behind the Granger–Johansen Representation Theorem
Oxford Bulletin of Economics and Statistics, EarlyView.ABSTRACT When can a vector time series that is integrated once (i.e., becomes stationary after taking first differences) be described in error correction form? The answer to this is provided by the Granger–Johansen representation theorem. From a mathematical point of view, the theorem can be viewed as essentially a statement concerning the geometry of ...

Likelihood Estimation for Stochastic Differential Equations with Mixed Effects
Scandinavian Journal of Statistics, EarlyView.ABSTRACT Stochastic differential equations provide a powerful tool for modelling dynamic phenomena affected by random noise. When time series are observed for several experimental units, it is often the case that some of the parameters vary between the individual experimental units.

Bayesian Poisson‐Lognormal Regression With Compositional Effect Shares for Multivariate Count Data
Environmetrics, Volume 37, Issue 4, May 2026.ABSTRACT Multivariate count data are central in community ecology and related fields, where interest lies in how environmental gradients and management actions jointly shape the abundances of many taxa. The Poisson‐lognormal (PLN) model is a natural workhorse in this setting, accommodating overdispersion and cross‐taxon dependence via a latent Gaussian

Burden of Nutritional Deficiencies: A Systematic Analysis for the GBD 2021
Health Science Reports, Volume 9, Issue 5, May 2026.ABSTRACT Background and Aims Nutritional deficiencies (ND) remain a major global health challenge, significantly affecting population well‐being. As part of the Global Burden of Disease (GBD) study, we conducted a comprehensive assessment of the prevalence, incidence, mortality, and disability‐adjusted life years (DALYs) attributed to ND from 1990 to ...

Microencapsulated Alkane Wax Melting: Measured by 1H NMR Relaxometry and Diffusometry
Magnetic Resonance in Chemistry, Volume 64, Issue 5, Page 483-493, May 2026.NMR relaxometry and diffusometry measurements detected greater molecular‐level disordering in microencapsulated n‐alkane waxes versus unencapsulated waxes throughout melting. ABSTRACT Phase change materials (PCMs) are useful for energy storage. Large latent heats make n‐alkane waxes effective PCMs.
