An Algorithm for Portfolio Optimization Problem [PDF]
Summary: Portfolio optimization is to find the stock portfolio minimizing the risk for a required return or maximizing the return for a given risk level. The seminal work in this field is the mean-variance model formulated as a quadratic programming problem.

Fabrication of Fibers With Complex Features Using Thermal Drawing of 3D‐Printed Preforms
3D printing enables rapid fabrication of macroscale polymer preforms with complex geometries. Thermal drawing then scales these structures into long fibers while preserving micron‐scale cross‐sectional features. This workflow provides a fast, low‐cost route to functional fibers with tailored geometries and material combinations for catheter, robotic ...
