Abstract: Methods of sample preparation for detection of nucleic acids (such as viral nucleic acids, for example, viral RNA) are provided. In some examples, the methods include contacting a sample with a solution including a buffer containing about 0-0.5 mM EDTA and a chelating resin and incubating the resulting mixture at a temperature of at least about 55° C.

Abstract: A telehealth terminal includes at least one processer configured to process signals and perform computing and arithmetic functions, a first camera in electrical communication with the at least one processor, the first camera being configured to pan, tilt, and zoom to capture an environment around the telehealth terminal, and a second camera in electrical communication with the at least one processor, the second camera being spaced from the first camera. The terminal also includes at least one microphone in electrical communication with the at least one processor; and at least one speaker in electrical communication with the at least one processor, wherein the at least one processor provides communication between a first user that operates the telehealth terminal and a second user that is remote from the telehealth terminal.

Abstract: A computer-implemented method of connecting terminals in a media stream includes receiving a first user input at a first terminal with a media agnostic software development kit (SDK), and initiating a session between the first terminal and a second terminal with a session controller based on the first user input received with the SDK. The method also includes selecting a media provider from among a plurality of media providers for use by the second terminal during the session with the session controller, where the session controller supports a media stream between the SDK at the first terminal and the selected media provider at the second terminal, and transmitting outgoing media data from the SDK at the first terminal to the selected media provider at the second terminal, or incoming media data from the selected media provider at the second terminal to the SDK at the first terminal.

Abstract: A stacked semiconductor device including a first substrate, a first insulating layer located on the first substrate, a second insulating layer located on the first insulating layer, a second substrate located on the second insulating layer, an external connection via extending through the second substrate in a first direction perpendicular to an upper surface of the second substrate and exposing an external connection pad, the external connection pad being located in the first insulating layer or the second insulating layer, and a protective ring formed in the second insulating layer and arranged to at least partially surround a sidewall of the external connection via with the first direction as an axial direction, but not to be exposed from the sidewall of the external connection via.

Abstract: A method of manufacturing a semiconductor device comprises: providing a stacked structure comprising a first wafer that includes a first substrate, a first insulating layer and a first electrical connector and a second wafer that includes a second substrate, a second insulating layer and a second electrical connector; forming a first portion of a TSV which overlaps at least part of the first and second electrical connectors and exposes a part of a surface of the first insulating layer; forming an insulating film that at least covers side surfaces and a bottom surface of the first portion; forming a first conductive barrier film retained on the side surfaces of the first portion; forming a second portion of the TSV that exposes the first and second electrical connectors; forming a conductive plug in the first and second portions, to interconnect the first and second electrical connectors.
