External Reflection From Two‐Photon Laser‐Printed Micromirrors Enables Photomechanical Actuation at a 90° Incident Angle

Advanced Functional Materials, EarlyView.
Light reflectance increases along incidence angle and transmittance significantly drops around 90‐degree incidence angle. Here, we report two‐photon laser printed micro mirrors that redirect the skimming light beam into normal light absorption. Using this technique, light‐driven micro walkers and grippers are demonstrated by using grazing incidence ...

Multiple Objective Linear Fractional Programming

Management Science, 1981
This paper presents a simplex-based solution procedure for the multiple objective linear fractional programming problem. By (1) departing slightly from the traditional notion of efficiency and (2) augmenting the feasible region as in goal programming, the solution procedure solves for all weakly efficient vertices of the augmented feasible region.

Solving linear fractional bilevel programs

Operations Research Letters, 2004
The authors give a geometrical characterization of the optimal solution to the linear fractional bilevel programming (LFBP) problem in terms of what is called a boundary feasible extreme point. It is assumed that the second level optimal solution sets are singletons. The results extend the characterization proved by \textit{Y. H. Liu} and \textit{S. M.
