Remarks on fixed point assertions in digital topology, 2
Applied General Topology, 2019 Several recent papers in digital topology have sought to obtain fixed point results by mimicking the use of tools from classical topology, such as complete metric spaces.

Comparison of Triply Periodic Minimal Surface Energy Absorbers Under Uniaxial Compressive Loading
Advanced Engineering Materials, EarlyView.This study investigates LCD 3D printed Triply Periodic Minimal Surface (TPMS) structures as mechanical energy absorbers. By comparing various base designs and layered combinations under uniaxial compression, it identifies that a Diamond‐Gyroid sandwich structure offers superior performance.

Advanced Functional Materials, EarlyView.Flexible piezoresistive pressure sensors underpin wearable and soft electronics. This review links sensing physics, including contact resistance modulation, quantum tunneling and percolation, to unified materials/structure design. We highlight composite and graded architectures, interfacial/porous engineering, and microstructured 3D conductive networks

Digital topological complexity numbers
TURKISH JOURNAL OF MATHEMATICS, 2018 Summary: The intersection of topological robotics and digital topology leads to us a new workspace. In this paper, we introduce the new digital homotopy invariant digital topological complexity number \(\operatorname{TC}(X,\kappa)\) for digital images and give some examples and results about it.

Advanced Functional Materials, EarlyView.The nanostructure, size, and function of mRNA‐loaded lipid nanoparticles are evaluated before drying, within polymer microneedles, and after rehydration. The results reveal the polymer and LNP loadings required to recover nanostructure and preserve the delivery performance in dry‐state formulations.

Digital fixed points, approximate fixed points, and universal functions
Applied General Topology, 2016 A. Rosenfeld [23] introduced the notion of a digitally continuous function between digital images, and showed that although digital images need not have fixed point properties analogous to those of the Euclidean spaces modeled by the images, there often ...

3D Printing Innovations in Polymeric Porous and Patterned Architecture
Advanced Functional Materials, EarlyView.Polymeric foams occupy a unique structural space between dense solids and open networks, where engineered void fraction governs mechanical compliance, thermal resistance, and mass transport. Additive manufacturing now enables precise spatial control over cellular architecture, unlocking designer foam structures across applications spanning crash ...

A framework for digital topology [PDF]
Proceedings of IEEE Systems Man and Cybernetics Conference - SMC, 2002 The main goal of this paper is to show the functional architecture of a framework for digital topology. This architecture has four levels, called device, logical, conceptual and continuous levels. In each one of them one can use several models according to the particular problem. The models in the device level represent the physical problem whereas the
