Suspended Tissue Open Microfluidic Patterning (STOMP)

Advanced Science, EarlyView.
Suspended Tissue Open Microfluidic Patterning (STOMP) is a method that enables precise spatial patterning within a single suspended tissue. By leveraging capillary pinning and open microfluidics, STOMP facilitates the creation of complex tissue interfaces such as diseased‐healthy boundaries and tissue‐tissue junctions. This method integrates mechanical

Schur-convexity for A-optimal designs

Journal of Mathematical Analysis and Applications, 1987
AbstractIn a regression setting, Chan (J. Math. Anal. Appl. 87 (1982), 45–50) gave a lower bound for the trace of the covariance matrix of the simple least squares estimate. For the case in which this lower bound cannot be reached, a sharper lower bound and a necessary and sufficient condition for its attainment are obtained using the idea of Schur ...

A Bifunctional Fibrous Scaffold Implanted with Amorphous Co2P as both Cathodic and Anodic Stabilizer for High‐Performance Li─S Batteries

Advanced Science, EarlyView.
An amorphous Co2P‐embedded porous carbon nanofiber membrane (A─Co2P/PCNF) via electrospinning/in situ phosphorization is developed to serve as the dual‐electrode stabilizer for Li─S batteries. The amorphization strategy enables more exposed undercoordinated Co sites with optimized d‐band centers, enhanced LiPSs adsorption/catalysis, and lithiophilicity‐

Reconstructing Three‐Dimensional Optical Anisotropy with Tomographic Müller‐Polarimetric Microscopy

Advanced Science, EarlyView.
Tomographic Müller polarimetric microscopy is a novel imaging technique that resolves 3D birefringent properties of bulky samples, unveiling hierarchical nanostructures at microscopic resolution. Based on incoherent visible‐light polarimetry, it achieves experimental simplicity by eliminating phase measurements.

Universal subgradient and proximal bundle methods for convex and strongly convex hybrid composite optimization [PDF]

arXiv
This paper develops two parameter-free methods for solving convex and strongly convex hybrid composite optimization problems, namely, a composite subgradient type method and a proximal bundle type method. Both functional and stationary complexity bounds for the two methods are established in terms of the unknown strong convexity parameter.
