The piston can include a first flow pathway that allows fluid flow between the first and third ports when in the first position and a second flow pathway that allows fluid flow between the second and third ports when in a second position. The piston can prevent fluid flow between the second and third ports when in the first position and prevent fluid flow between the first and third ports when in the second position.

Abstract: A method and an apparatus for training a transferable vision transformer (TVT) for unsupervised domain adaption (UDA) in heterogeneous devices are provided. The method includes that a heterogeneous device including one or more graphic processing units (GPUs) loads multiple patches into the TVT which includes a transferability adaption module (TAM). Furthermore, a patch-level domain discriminator in the TAM assigns weights to the multiple patches and determines one or more transferable patches based on the weights. Moreover, the heterogeneous device generates a transferable attention output for an attention module in the TAM based on the one or more transferable patches.

Abstract: An improved staining method is described for staining a biopolymer such as a peptide, a protein, an RNA, a DNA, an oligosaccharide or a complex containing a peptide, a protein, an RNA, a DNA, or an oligosaccharide in a matrix. The method includes the step of moving a staining reagent into the matrix using an electric force. The staining time can be dramatically reduced relative to conventional technologies. The improved staining method can particularly be used, for example, to stain proteins after gel separation. Other related methods and related kits are also described.

Abstract: Electrostatic discharge (ESD) protection circuits for self-protecting cascode stages are disclosed. In one example, an ESD protection circuit is described. A cascode stage is configured to selectively couple an output pad to a reference terminal. An ESD sensor may detect a change in voltage indicative of an ESD event occurring at the output pad, causing a gate drive to turn on the cascode stage to conduct ESD current in response to detection of the ESD event at the output pad. A leakage blocker is also included to prevent leakage current from the cascode stage to the gate drive while there is not an ESD event.

Abstract: A collaboration system includes a remote server system and one or more client devices connected to the remote server system, at least one of which being a first client device that includes a touch screen display. Upon receipt of a user instruction, the collaboration system opens a document at the first client device and displays the document on the touch screen display to a first user. The collaboration system detects a first comment on the document from the first user through interacting with the touch screen display. The collaboration system receives a second comment on the document from the remote server system. The second comment is generated by a second user of a second client device and transmitted to the remote server system through a computer network. The collaboration system displays, concurrently, the first comment and the second comment on the touch screen display.
