  • Patent number: 11442712
    Abstract: A method, apparatus and system required to realize an optimization opportunity are disclosed. If an expression involves unsequenced evaluations involving side-effects and optionally references, then the expression is translated into optimized code that may involve optimized register usage, or optimized use of the underlying vectorization hardware. An alias-analysis logic is able to identify must-not-alias relationships through such expression tree structures. These must-not-alias relationships are helpful not just in optimizing the performance of that particular expression (from which these must-not-alias relationships were derived) but also in the performance of any other surrounding program statements that access the state elements participating in these must-not-alias relationships.

  • Patent number: 11427682
    Abstract: The invention provides a new class of synthetic sequence-defined polymer (SDP) and a method of synthesizing the same. The synthetic sequence-defined polymers have dithiocarbamate incorporated to the backbone. The method introduces a functional group dithiocarbamate in the backbone by using a new support-free, protection-deprotection free three-component reaction strategy. Dithiocarbamate-SDP is prepared from a unique bifunctional monomer, CS2 and chloroacetyl chloride. Chloracetyl chloride is used as a co-monomer. Different functional groups may be introduced in the dithiocarbamate-SDP via custom synthesis of monomers with the desired functional group, using the method disclosed. The SDPs may undergo modular post-synthetic modification through multiple paths. SDP is produced in multi-gram scale at low cost and in an eco-friendly manner through the method. No hazardous waste is produced in the process as HCl gas released from the reaction may be neutralized by bicarbonate in the medium.
