AIMS Mathematics, 2021 In this study, we have introduced a new concept called $(m,n)$-harmonically polynomial convex functions on the co-ordinates. Then, we have demonstrated some properties of this definition.

Variational Methods in Convex Analysis [PDF]
Journal of Global Optimization, 2006 We use variational methods to provide a concise development of a number of basic results in convex and functional analysis. This illuminates the parallels between convex analysis and smooth subdifferential theory.

Advanced Engineering Materials, EarlyView.Morphological features of three defect types in metal additive manufacturing (AM)—lack of fusion, keyhole, and gas‐entrapped pores—are statistically characterized using best‐fit distributions evaluated via coefficient‐of‐determination, Kolmogorov–Smirnov test, and quantile–quantile plots.

Performance analysis of the convex non-convex total variation denoising model
AIMS MathematicsTotal variation (TV) regularization is a powerful tool in image denoising, but it often exhibits limited performance in preserving edges. In contrast, non-convex TV regularization can more effectively preserve edges and contours, albeit posing challenges

Advanced Engineering Materials, EarlyView.Previous studies on additive manufacturing primarily focus on the mechanical properties of as‐printed components. In the present work, researchers explore the potential of employing novel thermomechanical postprocessing techniques to improve the microstructure after printing.

A convex-analysis perspective on disjunctive cuts [PDF]
Mathematical Programming, 2005 We treat the general problem of cutting planes with tools from convex analysis. We emphasize the case of disjunctive polyhedra and the generation of facets. We conclude with some considerations on the design of efficient cut generators.

Scalable Fabrication of Height‐Variable Microstructures with a Revised Wetting Model
Advanced Engineering Materials, EarlyView.Height‐variable microstructures are fabricated using a scalable CO2 laser machining approach, enabling precise control of wettability through structural gradients. Classical wetting models fail to capture height‐induced effects, necessitating a revised theoretical framework.

Advanced Engineering Materials, EarlyView.This study investigates the complex mechanics of individual electrospun polycaprolactone fibers under small and large strains. Combining experiments with a visco‐hyperelastic damage model, this work reveals and quantifies these fibers’ nonlinear behavior, including strain‐stiffening, viscoelasticity, and damage.
