Deep co-added sky from Catalina Sky Survey images Open

A. Singhal, V. Bhalerao, A. Mahabal, Kaustubh Vaghmare, Santosh Jagade , et al. · 2021

A number of synoptic sky surveys are underway or being planned. Typically, they are done with small telescopes and relatively short exposure times. A search for transient or variable sources involves comparison with deeper baseline images,…

Microengineered 3D Collagen Gels with Independently Tunable Fiber Anisotropy and Directionality Open

Adeel Ahmed, Indranil M. Joshi, S. M. Larson, Mehran Mansouri, Shayan Gholizadeh , et al. · 2021

Cellular processes are linked to the alignment (anisotropy) and orientation (directionality) of collagen fibers (i.e., landscape) in the native extracellular matrix (ECM). Given the vital role that cell‐matrix interactions play in regulati…
