A Lexicon of Connected Components for Arabic Optical Text Recognition [PDF]

, 2011
Arabic is a cursive script that lacks the ease of character segmentation. Hence, we suggest a unit that is discrete in nature, viz. the connected component, for Arabic text recognition.

Sub‐Diffraction and Irreversibly Tunable Imaging With Potato Starch Lenses

Advanced Optical Materials, EarlyView.
Native potato starch granules function as sustainable birefringent microlenses that enable polarization‐controlled conventional and vortex lensing via spin‐to‐orbital angular momentum conversion. They provide sub‐diffraction and spiral‐contrast imaging, support vortex‐array generation with controllable topological‐charge sign, exhibit irreversible ...

Bidirectional Soft Catalysts for Improved Power Performance of Li‐S Batteries

Advanced Science, EarlyView.
A soft polymer‐metal catalyst is integrated into the binder to create a catalytically active microenvironment that accelerates bidirectional sulfur redox kinetics in lithium‐sulfur batteries. A model polyvinyl alcohol‐Cu catalyst enables high areal capacities at demanding current densities and stable cycling in pouch‐cell prototypes at 0.5 C, achieving
