Polarization‐Dependent Color Modulation in Electrodeposited Cellulose Nanocrystals and Birefringent Multilayers

open access: yesAdvanced Optical Materials, EarlyView.
This work demonstrates that wavelength selective reflection of circularly polarized light (CPL) of both handedness (right‐R or left‐L) can be achieved from self‐assembled cellulose nanocrystals (CNCs), breaking the inherent limitation of obtaining only L‐CPL reflection.

CottonSim: Development of an autonomous visual-guided robotic cotton-picking system in the Gazebo [PDF]

open access: yesarXiv
In this study, an autonomous visual-guided robotic cotton-picking system, built on a Clearpath's Husky robot platform and the Cotton-Eye perception system, was developed in the Gazebo robotic simulator. Furthermore, a virtual cotton farm was designed and developed as a Robot Operating System (ROS 1) package to deploy the robotic cotton picker in the ...

Computations of the Lipshitz-Sarkar Steenrod Square on Khovanov Homology [PDF]

open access: yesarXiv, 2012
Lipshitz and Sarkar recently introduced a space-level refinement of Khovanov homology. This refinement induces a Steenrod square operation $\Sq^2$ on Khovanov homology which they describe explicitly. This paper presents some computations of $\Sq^2$. In particular, we give examples of links with identical integral Khovanov homology but with distinct ...
