Inverse design for phase mask lithography
Optics Express, 2008 We have developed a method for designing the diffractive optics used in phase mask lithography. Genetic algorithms were used to inverse-design a grating's relief profile and associated exposure conditions so that desired periodic structures are formed. An experimentally promising grating designed to produce helices is demonstrated.

RIEMANN ZEROS AND THE INVERSE PHASE PROBLEM [PDF]
Modern Physics Letters B, 2013 Finding a universal method of crystal structure solution and proving the Riemann hypothesis are two outstanding challenges in apparently unrelated fields. For centro-symmetric crystals however, a connection arises as the result of a statistical approach to the inverse phase problem.

PES-Kaolin Mixed Matrix Membranes for Arsenic Removal from Water
Membranes, 2017 The aim of this work was the fabrication and the characterization of mixed matrix membranes (MMMs) for arsenic (As) removal from water. Membrane separation was combined with an adsorption process by incorporating the kaolin (KT2) Algerian natural clay in

Inverse Alexander phase detector [PDF]
Electronics Letters, 2016 An improved bang‐bang phase detector (PD) for multi Gb/s clock and data recovery (CDR) circuits is presented. The proposed PD is based on inverting the Alexander PD. In a typical subsampled CDR circuit, this Inverse Alexander PD results in a ten times better bit error rate (BER) compared with the conventional Alexander PD.

Reconstructing enzyme evolution by protein engineering
FEBS Letters, EarlyView.Natural enzyme evolution can be retraced by protein engineering methods such as directed evolution, rational design, and ancestral sequence reconstruction. These approaches reveal how enzymes emerged from ligand‐binding scaffolds, developed varying substrate preferences, formed oligomeric complexes, adapted to environmental changes, and evolved novel ...
