Algorithm: Regularized Orthogonal Matching Pursuit (ROMP)
This paper seeks to bridge the two major algorithmic approaches to sparse signal recovery from an incomplete set of linear measurements – L1-minimization methods and iterative methods (Matching Pursuits). We find a simple regularized version of the Orthogonal Matching Pursuit (ROMP) which has advantages of both approaches: the speed and transparency of OMP and the strong uniform guarantees of t...
متن کاملGeneral synthetic route to cell-permeable block copolymers via ROMP.
The applications of block copolymers are myriad, ranging from electronics to functionalized resins to therapeutics. The ring-opening metathesis polymerization (ROMP) is an especially valuable reaction for block copolymer assembly because each block can be generated with length control. We sought to use this polymerization to expand the repertoire of block copolymers by implementing a strategy t...
متن کاملRAPID COMMUNICATION Phosphonic Acid-Based Amphiphilic Diblock Copolymers Derived from ROMP
Forming nanostructures with controlled size and shape is one of the most challenging tasks in material science. Amphiphilic block copolymers are of special interest because of their ability to self-assemble on the nanoscale. The formation of micelles has potential applications such as in drug delivery, biosensors, and gene therapy. Ring-opening metathesis polymerization (ROMP) is a versatile te...
متن کاملSequential ROMP of cyclooctenes as a route to linear polyethylene block copolymers.
AB diblock copolymers were prepared by sequential ring-opening metathesis polymerization of cyclooctenes catalyzed by a Ru-based Grubbs catalyst. The relatively slow polymerization of cis-3-phenylcyclooct-1-ene (3PC) or cis-cyclooct-2-en-1-yl acetate (3AC) was first carried out and then followed by the faster polymerization of unsubstituted cis-cyclooctene (COE) from the active Ru-alkylidene ch...
متن کاملModular Synthesis of ABC Type Block Copolymers by ‘‘Click’’ Chemistry
Heterotelechelic polystyrene (PS), poly(tert-butyl acrylate) (PtBA), and poly (methyl acrylate) (PMA), containing both azide and triisopropylsilyl (TIPS) protected acetylene end groups, were prepared in good control (Mw/Mn 1.24) by atom transfer radical polymerization (ATRP). The end groups were independently applied in two successive ‘‘click’’ reactions, that is: first the azide termini were f...
