The parallax view: the military origins of holography [PDF]
, 2009 The title of this piece is meant to evoke at least three sources. The first – and perhaps the only obvious one – concerns the ability of holograms to display parallax, a shifting of visual viewpoint that allows a three-dimensional image to reveal ...

Advanced Science, EarlyView.This study constructed the W1/O/W2 emulsion–based targeted therapy delivery system for ulcerative colitis (UC) utilizing LCC as surfactant for the first time. This multifunctional emulsion offered certain therapeutic advantages for UC, including targeted colonic delivery of active compounds, synergistic modulation of gut microbiota through combined ...

Advanced Science, EarlyView.This paper proposes a hierarchical reconfigurable metasurface architecture (HRMA) to achieve comprehensive electromagnetic parameter modulation and on‐demand polymorphic function switching. The reconfigurable metasurface is divided into a programmable core (PC) and scenario‐guided functional modules (FMs), exhibiting significant flexibility and ...
