Abstract: This invention relates to methods for oligonucleotide synthesis, specifically the synthesis of oligonucleotides that contain a high content of guanine monomers. In more detail, the invention relates to a method for coupling a nucleoside phosphor amidite during the synthesis of an oligonucleotide to a universal support, to a first nucleoside, or to an extending oligonucleotide.

Abstract: Techniques are described for determining an identifier (ID) that identifies a vehicle employed in a ridesharing service, presenting the ID through a presentation device of the vehicle, and communicating the ID to a passenger to help guide the passenger to the appropriate vehicle. The ID may be presented in a presentation device, such as a light-emitting diode (LED) display, that is temporarily or permanently affixed to the vehicle. The ID may also be communicated for presentation by a passenger device of the passenger. In some implementations, the ID is a particular color that is selected on the driver device of the driver of the vehicle, such that the presentation device displays the selected color. The presentation device may also present text data.
