Advanced Healthcare Materials, EarlyView.Three‐dimensional bioprinting transforms breast cancer modeling from simple constructs into spatially organized, multicellular, perfused, and patient‐derived platforms. This review shows how bioinks, cellular composition, architecture, and flow govern tumor behavior and drug response, while revealing why complexity alone is insufficient without ...

Optimal designs for 3D shape analysis with spherical harmonic descriptors [PDF]
, 2004 We determine optimal designs for some regression models which are frequently used for describing 3D shapes. These models are based on a Fourier expansion of a function defined on the unit sphere in terms of spherical harmonic basis functions.

Leaftronics: Bio‐Fractal Scaffolds From Leaf Venation for Low‐Waste Electronics
Advanced Materials, EarlyView.“Leaftronics” transforms naturally evolved leaf venation into quasi‐fractal scaffolds for sustainable electronics. Polymer‐infiltrated leaf skeletons can be used to fabricate ultra‐smooth, reflow‐ and thin‐film‐compatible decomposable substrates, while making the same lignocellulose networks conducting results in flexible transparent electrodes.

Topology of Platonic Spherical Manifolds: From Homotopy to Harmonic Analysis
, 2015 We carry out the harmonic analysis on four Platonic spherical three-manifolds with different topologies. Starting out from the homotopies (Everitt 2004), we convert them into deck operations, acting on the simply connected three-sphere as the cover, and ...

Light Analysis of Paintings at Scale Using Spherical Harmonics
Electronic ImagingLight is abstract. Light is difficult to describe with words. Unlike other pictorial motifs such as perspective, light depiction eludes fixed rules and defies straightforward measurement. This study presents a preliminary step towards measuring light information from paintings at scale.
