    Abstract: A PCR kit-of-parts is described. The kit-of-parts comprises a first oligonucleotide bound to a bead by a cleavable linker; a second oligonucleotide bound to a bead by a cleavable linker; and an enzyme bound to a bead by a cleavable linker; wherein the first and second oligonucleotide form an oligonucleotide pair complementary to a nucleic acid of interest and the enzyme is capable of extending nucleic acid strands; and each cleavable linker is independently selected from a photocleavable linker and a thermally cleavable linker. Also described is a method of performing PCR and a PCR system.

    Abstract: A three-dimensional printing kit can include a particulate build material including from about 80 wt % to about 100 wt % metal particles, a binder fluid including water and latex particles in an amount of from about 5 wt % to about 30 wt % based on a total weight of the binder fluid, and an amine-bearing phosphonic adhesion promoter included in the binder fluid in an amount of from about 0.05 wt % to about 3.5 wt % based on a total amount of the binder fluid, or a separate adhesion promoter fluid in an amount of from about 0.1 wt % to about 5 wt % based on a total amount of the adhesion promoter fluid.

    Abstract: An example apparatus may include a hardware component, a memory, and a processor. The processor may retrieve a firmware for the hardware component subsequent to the firmware being loaded on the hardware component. The processor may determine that a firmware signature associated with the firmware is stored in the memory. In some examples, in response to a determination that the firmware signature associated with the firmware is stored in the memory, the processor may initiate authentication of the firmware.

    Abstract: An example computing device comprises a memory to store control instructions, and a processor to: perform a first authentication of the control instructions using a first key; and in response to receipt of a command to enable a second authentication of the control instructions, add a second key to a one-time programmable portion of the memory, wherein the command is signed using the first key, the second key to perform a second authentication of the control instructions with the first key to perform the first authentication of the control instructions.

    Abstract: A method may include obtaining, using a head detection model and for an image of a video stream, head detection information, where the head detection information identifies heads detected in the image. Method may also include obtaining buffer bounding boxes. Obtaining the buffer bounding boxes may include obtaining head buffer bounding boxes for the heads detected in the image, and combining at least two of the head buffer bounding boxes into a proximity buffer bounding box. The method may furthermore include identifying a set of templates based on the buffer bounding boxes. Method may in addition include creating, individually, head frame definitions for the buffer bounding boxes using the set of templates, generating an image frame definition that combines the head frame definitions, and processing the video stream using the image frame definition.
