Abstract: To provide the continuous playback of content, a content server may provide code to a requesting device that causes the requesting device to play streaming content delivered in chunks or other portions without disruption in playback. The requesting device may execute the code by a browser or other application, which may cause the requesting device to determine whether a data buffer is empty or nearly empty and request additional content from a streaming server if the data buffer is empty or nearly empty. The process may be repeated a number of times each second for the duration of the playback of the content in order to enable continuous playback of the content regardless of any throttling of the code execution or content playback attempted to be imposed by a browser or other application.

Abstract: Unsymmetrical bisazides containing chelating and non-chelating azido groups undergo chemoselective three-component copper(I)-catalyzed azide-alkyne conjugation reactions with two different alkyne molecules. In conjunction with the reactivity gap between aromatic and aliphatic alkynes, a bistriazole molecule can be generated with an excellent regioselectivity by mixing two alkynes and a bisazide in a single reaction container. This method is applicable in aqueous solutions at neutral pH, which may lend utilities in bioconjugation applications.
