The transcendental Risch differential equation

Journal of Symbolic Computation, 1990
We present a new rational algorithm for solving Risch differential equations in towers oftranscendental elementary extensions. In contrast to a recent algorithm of Davenport we do not require a progressive reduction of the denominators involved, but use weak normality to obtain a formula for the denominator of a possible solution.

Inelastically scattering particles and wealth distribution in an open economy

, 2003
Using the analogy with inelastic granular gasses we introduce a model for wealth exchange in society. The dynamics is governed by a kinetic equation, which allows for self-similar solutions.

Relations between Solutions of Differential Equations and Small Functions

Abstract and Applied Analysis, 2012
We investigate relations between solutions, their derivatives of differential equation f(k)+Ak−1f(k−1)+⋯+A1f’+A0f=0, and functions of small growth, where Aj  (j=0,1,…,k−1) are entire functions of finite order.

Classical-quantum correspondence for shape-invariant systems

, 2015
A quantization procedure, which has recently been introduced for the analysis of Painlev\'e equations, is applied to a general time-independent potential of a Newton equation.

In Situ Graph Reasoning and Knowledge Expansion Using Graph‐PRefLexOR

Advanced Intelligent Discovery, EarlyView.
Graph‐PRefLexOR is a novel framework that enhances language models with in situ graph reasoning, symbolic abstraction, and recursive refinement. By integrating graph‐based representations into generative tasks, the approach enables interpretable, multistep reasoning.

Bethe Ansatz calculation of the spectral gap of the asymmetric exclusion process

, 2003
We present a new derivation of the spectral gap of the totally asymmetric exclusion process on a half-filled ring of size L by using the Bethe Ansatz.

Spiritual and religious information experiences: An Annual Review of Information Science and Technology (ARIST) paper

Journal of the Association for Information Science and Technology, EarlyView.
Abstract This chapter examines the contours of the religious and spiritual information experiences subfield through a review and content analysis of selected contributions from the past two decades in both information science and related fields. The research question that guides this review is: How have spirituality and religion been conceptualized in ...

In search of existential authenticity: Information behaviors during a time of personal transformation

Journal of the Association for Information Science and Technology, EarlyView.
Abstract Many people make changes to their lives to provide a greater sense of value, purpose, or coherence to their everyday existence. One goal in making such changes is to improve their sense of existential authenticity, a feeling that their lives are being lived in what they see as meaningful and productive ways.
