  • Publication number: 20240125764
    Abstract: The present disclosure provides a composition comprising a solid support, a plurality of tethered oligonucleotides attached to the solid support, and a plurality of untethered oligonucleotides hybridized to the tethered oligonucleotides. An untethered oligonucleotide can comprise, attached via the 5? end, a cell, or an effector molecule. Hybridization of an untethered oligonucleotide to a tethered oligonucleotide generates an enzyme cleavage site, which allows for temporally controlled removal of an effector molecule. The present disclosure provides methods of temporally modulating the activity and/or phenotype of a cell. The present disclosure provides a solid support comprising patterned tethered oligonucleotides attached thereto; and methods of making the solid support.

  • Publication number: 20240112825
    Abstract: Methods and dispensers for dispensing atomic objects are provided. An example method for dispensing atomic objects includes depositing a reaction agent and a composition comprising the atomic objects inside a crucible chamber of a crucible; and heating the composition comprising the atomic objects to an atomizing reaction temperature to cause an atomizing chemical reaction to occur. The reaction component comprises a material that is a participant in the atomizing chemical reaction, the result of the atomizing chemical reaction is elemental atomic objects, and (c) the elemental atomic object is dispensed during the atomizing chemical reaction.

  • Patent number: 11878134
    Abstract: A balloon catheter for use with a guidewire includes an elongated, tubular shaft extending in a longitudinal direction, said shaft having a proximal end and a distal end. An inflatable balloon is connected to the distal end of the shaft, the balloon including a working surface. A radiopaque identifier is provided for identifying the working surface. A receiver adjacent the proximal end of the shaft is adapted for allowing the shaft to move relative to the receiver in at least the longitudinal direction.

  • Publication number: 20230187096
    Abstract: Embodiments relate to initializing and/or performing state preparation for an atomic object. The controller controls first manipulation sources to provide first manipulation signals and second manipulation sources to provide second manipulation signals. The first and second manipulation signals are incident on the atomic object. The atomic object has a nuclear spin greater than one half. A ground state manifold of the atomic object comprises one or more selected ground manifold states and non-selected ground manifold states. The first manipulation signals are configured to drive transitions from the non-selected ground manifold states to one or more pumped manifolds of the atomic object and suppress transitions out of the selected ground manifold states. The second manipulation signals are configured to stimulate the atomic object to decay a pumped manifold into a decayed state, wherein there is a non-zero probability that the decayed state is one of the selected ground manifold states.

  • Patent number: 11433181
    Abstract: A flow rate control device having features for selectively controlling the flow rate of a fluid over a continuous range of flow rates is provided. In particular, a flow rate control device including an inflatable flow restrictor is provided, where the flow restrictor is selectively inflatable to occlude a flow path of a fluid to thereby control the flow rate of the fluid. A flow rate control mechanism comprising a flow restrictor also is provided, the flow restrictor having an inflatable balloon for occluding a flow path of a fluid to selectively control the flow rate of the fluid.

  • Patent number: 11147953
    Abstract: An inflatable balloon is provided. The balloon includes a central lumen open at both ends of the balloon and connected to a gap formed in one sidewall of the balloon. This arrangement may provide the balloon with a generally C-shaped profile with the open central lumen within the balloon along a center axis thereof, such as to allow for perfusion. The balloon may also include an inflation port offset from a central axis and a shaft including an inflation lumen connected to the inflation port. A sheath may also be provided with a window through which the balloon may project in use.
