Multistate Density Functional Theory: Theory, Methods, and Applications

open access: yesWIREs Computational Molecular Science, Volume 15, Issue 5, September/October 2025.
Multistate density functional theory with nonorthogonal state interaction (MSDFT‐NOSI) extends the scope and application of density functional theory to a wide range of systems that cannot be adequately treated in the Kohn–Sham framework. Illustrated examples include conical intersection in a photochemical reaction, excited‐state energy transfer ...

Linear functional differential equations possessing solutions with a given growth rate

open access: yesJournal of Inequalities and Applications, 2005
We establish optimal, in a sense, conditions under which, for arbitrary forcing terms from a suitable class, a linear inhomogeneous functional differential equation in a preordered Banach space possesses solutions satisfying a certain growth restriction.

Simulation of Inhomogeneous Refractive Index Fields Induced by Hot Tailored Forming Components

open access: yesAdvanced Engineering Materials, Volume 27, Issue 16, August 2025.
This article presents a simulation model for simulating inhomogeneous refractive index fields (IRIF) in hot‐forged components, accounting for thermal influences and complex geometries. Through this simulation, a priori knowledge about the propagation of the IRIF can be obtained, allowing for the positioning of the component or an optical measurement ...

Sequences suffice for pointfree uniform completions

open access: yesJournal of the London Mathematical Society, Volume 112, Issue 2, August 2025.
Abstract Completions of metric spaces are usually constructed using Cauchy sequences. However, this does not work for general uniform spaces, where Cauchy filters or nets must be used instead. The situation in pointfree topology is more straightforward: the correct completion of uniform locales can indeed be obtained as a quotient of a locale of Cauchy

Identifying challenges in crowdfunded product development: a review of Kickstarter projects

open access: yesDesign Science, 2018
This paper provides an empirical review of the reward-based crowdfunding platform Kickstarter.com, with the aim to explore and identify challenges in crowdfunded product development, which consequently can lead to failure of the crowdfunding campaign ...

How Effective Are Machine Learning and Doubly Robust Estimators in Incorporating High‐Dimensional Proxies to Reduce Residual Confounding?

open access: yesPharmacoepidemiology and Drug Safety, Volume 34, Issue 5, May 2025.
ABSTRACT Background Residual confounding presents a persistent challenge in observational studies, particularly in high‐dimensional settings. High‐dimensional proxy adjustment methods, such as the high‐dimensional propensity score (hdPS), are widely used to address confounding bias by incorporating proxies for unmeasured confounders. Extensions of hdPS

Almost quasi-Urbanik structures and theories

open access: yesҚарағанды университетінің хабаршысы. Математика сериясы
The notions of almost quasi-Urbanik structures and theories, and studied possibilities for the degrees of quasi-Urbanikness, both for existential and universal cases were introduced. Links of these characteristics and their possible values are described.

Structures on the space of financial events

open access: yesAtti della Accademia Peloritana dei Pericolanti : Classe di Scienze Fisiche, Matematiche e Naturali, 2008
In this paper we endow the space of financial events with some structures, each of them represents basic facts of financial mathematics. We introduce a preordered structure, that we shall call the usual preorder of the financial events plane, and an ...
