Polymer Engineering &Science, EarlyView.Study on transient parison formation at various strokes during extrusion of Newtonian and viscoelastic fluids. In the presence of an offset between the mandrel and the bushing, Newtonian fluids exhibit a reduction in extrudate diameter, whereas viscoelastic fluids display diameter swelling only at flow rates exceeding a critical threshold.

Structure and Migration Mechanisms of Oxygen Interstitial Defects in β‐Ga2O3
physica status solidi (b), EarlyView.The structures and diffusion mechanisms of interstitial oxygen in different charge states in β‐Ga2O3 are extensively studied using density functional theory. The results provide a detailed map of the potential energy surface for oxygen interstitials in β‐Ga2O3 and demonstrate how these ions migrate between different rings in the structure.

Anticlastic Curvature and Material Freedom
physica status solidi (b), EarlyView.Anticlastic curvature occurs in bent bars for positive Poisson's ratio; synclastic curvature occurs for negative Poisson's ratio provided the material is homogeneous and elastic. Some planar negative Poisson's ratio materials exhibit anticlastic saddle curvature rather than convex curvature in bending due to effects of 3D structure.

Beyond Kagome: p$p$‐Bands in Kagome Metals
Advanced Quantum Technologies, EarlyView.Recent studies on quantum materials where transition‐metal atoms give rise to d$d$‐bands typical of kagome metals are reviewed. Using examples from several material families – AV3Sb5${\rm AV}_3{\rm Sb}_5$, FeGe, RV6Sn6${\rm RV}_6{\rm Sn}_6$, and LaRu3Si2${\rm LaRu}_3{\rm Si}_2$ – it is argued that p$p$‐bands contributed by elements beyond the kagome ...

Generalized Iterative Methods for Solving Double Saddle Point Problem
پژوهشهای ریاضی, 2019 In this paper, we develop some stationary iterative schemes in block forms for solving double saddle point problem. To this end, we first generalize the Jacobi iterative method and study its convergence under certain condition.

Bicontinuous Interconnected Porous Biomaterials for Tissue Engineering and Regeneration
Small Science, EarlyView.Solvent transfer‐induced phase separation transforms bioinert polyethylene glycol diacrylate into bioactive scaffolds featuring bicontinuous interconnected porosity, with negative Gaussian curvature, and unique topographical patterning. These attributes enable stem cell attachment, proliferation, and differentiation without basement membrane matrix ...
