Truncated Truncated Dodecahedron and Truncated Truncated Icosahedron Spaces

Cumhuriyet Science Journal, 2019
The theory of convex sets is a vibrant and classicalfield of modern mathematics with rich applications. The more geometric aspectsof convex sets are developed introducing some notions, but primarily polyhedra.A polyhedra, when it is convex, is an ...

Study on the Contact Parameter Calibration of the Maize Kernel Polyhedral Discrete Element Model

Agriculture
During maize production and transportation, maize kernels frequently interact with mechanical components. To accurately simulate the interaction process between maize and mechanical components, it is essential to establish a reliable maize kernel model ...

Lipid Nanoparticles for the Delivery of CRISPR/Cas9 Machinery to Enable Site‐Specific Integration of CFTR and Mutation‐Agnostic Disease Rescue

Advanced Functional Materials, EarlyView.
Lipid nanoparticles (LNPs) are optimized to co‐deliver Cas9‐encoding messenger RNA (mRNA), a single guide RNA (sgRNA) targeting the endogenous cystic fibrosis transmembrane conductance regulator (CFTR) gene, and homologous linear double‐stranded donor DNA (ldsDNA) templates encoding CFTR.

Rigid ball-polyhedra in Euclidean 3-space

, 2012
A ball-polyhedron is the intersection with non-empty interior of finitely many (closed) unit balls in Euclidean 3-space. One can represent the boundary of a ball-polyhedron as the union of vertices, edges, and faces defined in a rather natural way.

Patterning the Void: Combining L‐Systems with Archimedean Tessellations as a Perspective for Tissue Engineering Scaffolds

Advanced Functional Materials, EarlyView.
This study introduces a novel multi‐scale scaffold design using L‐fractals arranged in Archimedean tessellations for tissue regeneration. Despite similar porosity, tiles display vastly different tensile responses (1–100 MPa) and deformation modes. In vitro experiments with hMSCs show geometry‐dependent growth and activity. Over 55 000 tile combinations

Spiritual Integration of Migrants: A Lisbon Case Study Within the Common Home Agenda and Polyhedron of Intelligibility Framework

Religions
Migration is a multidimensional process that reshapes identities and communities. This article adopts a polyhedral framework inspired by Pope Francis’s Laudato si’ and Michel Foucault’s concepts of “subjectivation” and the “polyhedron of intelligibility”.
