This invention provides a process for extruding a PLA resin using high levels of CO2. Excellent quality, low density foam is produced easily and reproducibly. The foams arc capable of being heat-annealed to induce significant crystallinity, even when an ordinarily amorphous PLA resin is used.

Polylactide polymers are reacted with an epoxy-functional acrylate polymer to introduce long-chain branching into the polymer. The acrylate polymer provides a flexible means for introducing a controllable amount of branching into the polylactide polymer, with little risk of forming gelled or highly crosslinked structures. The branched polylactide polymers have excellent melt rheological properties that make them more easily processable in various melt-processing applications.

Cartridges useful for mixing materials, such as fluidic materials are provided. A cartridge typically includes a body structure having surfaces that define a cavity with upper and lower portions. A rotatable member generally extends along a horizontal axis in the upper portion of the cavity. One or more protrusions typically extend outward from the rotatable member and into the lower portion of the cavity, and are configured to mix the material when the material is disposed in the cavity. Related mixing stations, systems, kits, and methods are also provided.

Techniques have been developed to facilitate the capture performances on handheld or other portable computing devices and, in some cases, the pitch-correction and mixing of such vocal performances with backing tracks for audible rendering on such devices. Captivating visual animations and/or facilities for listener comment and ranking are provided in association with an audible rendering of a performance, e.g., a vocal performance captured and pitch-corrected at another similarly configured mobile device and mixed with backing instrumentals and/or vocals. Geocoding of captured vocal performances and/or listener feedback may facilitate animations or display artifacts in ways that are suggestive of a performance or endorsement emanating from a particular geographic locale on a user manipulable globe. In this way, implementations of the described functionality can transform otherwise mundane mobile devices into social instruments that foster a unique sense of global connectivity and community.

Secure web-based messaging according to a “push” paradigm is augmented by specific, intended recipient authentication. In particular, a document can be sent to a specified, intended recipient through the Web using e-mail recipient notification, and the recipient is authenticated prior to delivering the document to the recipient. Such authentication prevents a cracker from snooping a delivery notification e-mail message and retrieving the document prior to retrieval by the true intended recipient. In addition, such authentication of the recipient is driven by the sender such that prior participation by the recipient in the messaging system according to the present invention is required.

摘要:
A server interacts with a sender to form a package which can include one or more attached data files to be sent to one or more recipients, and the server applies a policy established by a policy authority of the sender to the package. Since the sever both forms the package through interaction with the sender and applies the policy, any violations of the policy by the package can be brought to the sender's attention during an interactive session with the sender and before encryption of all or part of the package. As a result, the sender is educated regarding the policy of the sender's policy authority, and the sender can modify the package immediately to comport with the policy. The server delivers the package to the one or more intended recipients by sending notification to each recipient and including in such notification package identification data, e.g., a URL by which the package can be retrieved. The policy of the policy authority can be specified as a list of associations between one or more conditions and one or more actions to be carried out upon satisfaction of the associated conditions.
