Testing Hypotheses of Covariate Effects on Topics of Discourse

Statistical Analysis and Data Mining: An ASA Data Science Journal, Volume 19, Issue 2, April 2026.
ABSTRACT We introduce an approach to topic modeling with document‐level covariates that remains tractable in the face of large text corpora. This is achieved by de‐emphasizing the role of parameter estimation in an underlying probabilistic model, assuming instead that the data come from a fixed but unknown distribution whose statistical functionals are

Computing the fuzzy Laplace transform via Homotopy Perturbation Method

Journal of Interpolation and Approximation in Scientific Computing, 2014
In this paper, the homotopy perturbation method (HPM) is applied to compute the fuzzy Laplace transform of fuzzy functions. The basic properties of the fuzzy Laplace transform are again obtained by HPM and examples assuring the applicability of HPM are presented.

Pluralistic Research Designs in Management and Organization Studies: Integrating Paradigms Through Structural and Anti‐structural Frameworks

British Journal of Management, Volume 37, Issue 2, April 2026.
Abstract This paper focuses on pluralistic research designs in management and organization studies. While advocates often present such approaches as a means of reconciling practical relevance with scientific rigour, their philosophical coherence remains underexplored, particularly in relation to the paradigm debates of the 1980s and 1990s. Our analysis

Artificial Intelligence in Gastrointestinal Motility Diagnostics: A Systematic Review

Neurogastroenterology &Motility, Volume 38, Issue 4, April 2026.
Artificial Intelligence shows strong potential to improve the accuracy, efficiency, and standardization of gastrointestinal motility diagnostics. In time, this will improve patient care, but for now the referenced studies throughout the GI tract lack the required rigor for clinical implementation. ABSTRACT Background The assessment of gastrointestinal (

Fuzzy Fractional Caputo Derivative of Susceptible-Infectious- Removed Epidemic Model for Childhood Diseases

Mathematics
In this work, the susceptible-infectious-removed (SIR) dynamics are considered in relation to the effects on the health system. With the help of the Caputo derivative fractional-order method, the SIR epidemic model for childhood diseases is designed ...

Solution of fuzzy singular integral equation with Abel’s type kernel using a novel hybrid method

Advances in Difference Equations, 2020
In this paper, we are applying a novel analytical hybrid method to find the solution of a fuzzy Volterra Abel’s integral equation of the second kind. The fuzzy number is used in its parametric form under which the fuzzy Volterra Abel’s integral equation ...

The Evolving Landscape of Modern Regression: A Systematic Review and Mapping Study of Penalized, Algorithmic, and Interpretable Models

WIREs Data Mining and Knowledge Discovery, Volume 16, Issue 1, March 2026.
This systematic review maps 50 years of regression methodology, tracing its evolution from ridge stabilization and penalized estimation to Bayesian, ensemble, and explainable‐AI frameworks. The analysis reveals a unified progression toward interpretable, cross‐domain modeling that integrates statistical rigor, computational scalability, and epistemic ...

Kidney Tumor Segmentation With a Multistage Adaptive Boundary‐Aware Network

Annals of the New York Academy of Sciences, Volume 1557, Issue 1, March 2026.
This study introduces MABS‐Net, a multistage adaptive boundary‐aware network for kidney tumor segmentation. By integrating boundary‐aware multiscale feature extraction, a three‐stage cascaded architecture, and contrastive learning with online hard example mining, this model effectively captures subtle edge cues and boosts tissue discrimination.

An approach to a fuzzy problem using the fuzzy Laplace transform under the generalized differentiability

Malaya Journal of Matematik, 2020
In this paper, the solutions of a second-order fuzzy initial value problem are studied by the fuzzy Laplace transform under the generalized differentiability. An example is solved. Finally, conclusions are given.
