摘要:
Metal-organic framework (MOFs) compositions based on nitrogen donor-based organic bridging ligands, including ligands based on 1,3-diketimine (NacNac), bipyridines and salicylaldimine, were synthesized and then post-synthetically metalated with metal precursors, such as complexes of first row transition metals. Metal complexes of the organic bridging ligands could also be directly incorporated into the MOFs. The MOFs provide a versatile family of recyclable and reusable single-site solid catalysts for catalyzing a variety of asymmetric organic transformations. The solid catalysts can also be integrated into a flow reactor or a supercritical fluid reactor.

Various systems for delivering phase-change particulate ice slurries to targeted areas or organs of a patient are provided. Systems for delivering phase-change particulate ice slurries include a slurry reservoir and a conduit for delivering slurry from the reservoir to the patient. The conduit may include multiple components, including a section of medical tubing, an insertion tip for directing the out flow of slurry to the targeted area, and one or more transition fittings to adapt the tubing to the insertion tip. Interfaces between the various components that form the slurry flow path are configured so that there are no sudden reductions in the cross sectional area of the flow path. Any narrowing of the flow path occurs in a gradual tapered manner. The entire flow path remains substantially free of all obstacles that may tend to trap particles and lead to plugging of the flow path.

Example embodiments allow for networks of hybrid controllers that can be computed efficiently and that can adapt to changes in the system(s) under control. Such a network includes at least one hybrid controller that includes a dynamic sub-controller and a learned system sub-controller. Information about the ongoing performance of the system under control is provided to both the hybrid controller and to an over-controller, which provides one or more control inputs to the hybrid controller in order to modify the ongoing operation of the hybrid controller. These inputs can include the set-point of the hybrid controller, one or more parameters of the dynamic controller, and an update rate or other parameter of the learned system controller. The over-controller can control multiple hybrid controllers (e.g., controlling respective sub-systems of an overall system) and can, itself, be a hybrid controller.

摘要:
Cavity resonators are promising resources for quantum technology, while native nonlinear interactions for cavities are typically too weak to provide the level of quan-turn control required to deliver complex targeted operations. Here we investigate a scheme to engineer a target Hamiltonian for photonic cavities using ancilla qubits. By off-resonantly driving dispersively coupled ancilla qubits, we develop an optimized approach to engineering an arbitrary photon-number dependent (PND) Hamiltonian for the cavities while minimizing the operation errors. The engineered Hamiltonian admits various applications including canceling unwanted cavity self-Kerr interac-tions, creating higher-order nonlinearities for quantum simulations, and designing quantum gates resilient to noise. Our scheme can be implemented with coupled microwave cavities and transmon qubits in superconducting circuit systems.

The invention is directed to one or more antisense polynucleotides and their use in pharmaceutical compositions in a strategy to induce exon skipping in the γ-sarcoglycan gene in patients suffering from Limb-Girdle Muscular Dystrophy-20 (LGM-D)2C) or in patients at risk of such a disease. The invention also provides methods of preventing or treating muscular dystrophy, e.g., LGMD)2C, by exon skipping in the gamma sarcoglycan gene using antisense polynucleotides. Accordingly, in some aspects the in-vention provides an isolated antisense oligonucleotide, wherein the oligonucleotide specifically hybridizes to an exon target region of a γ-sarcoglycan RNA. In another aspect, the invention provides a method of inducing exon-skipping of a gamma sarcoglycan RNA, comprising delivering an antisense oligonucleotide or a composition to a cell.
