Meta‐Rod Mechanical Metamaterials With Programmable Reconfiguration
Advanced Functional Materials, EarlyView.Existing mechanical metamaterials achieve programmable large deformations in planar square or cubic configurations, restricted by required complex boundary conditions. This research proposes a 1D metamaterial, Meta‐rod, with linear, bending, twisting, area, and volume deformation modes.

Geometric Analysis of Undeformed Chip Thickness in Ball-Nosed End Milling
JSME International Journal Series C, 2004 This paper clarifies the analysis method for the undeformed chip thickness and the geometric influence of the tool orientation on the ball-nosed end milling. It has been firstly pointed out that the geometric situations on the determination of the thickness are categorized in three cases based on the relationship among the milling parameters.

Material‐Induced Nuclear Deformation Controls Chromatin Architecture in Adipose Stem Cells
Advanced Science, EarlyView.Tuning cell and cytoskeleton mechanics modulated nuclear shape and heterochromatin organization in ASCs. Distinct cytoskeletal architectures induced nuclear morphologies from oblate to prolate ellipsoids. Large elongated cells with a structured actin cap exhibited high nuclear strain, driving nuclear envelope deformation and heterochromatin ...
