Methods and apparatuses for assessing the behavior of high temperature bonding systems such as sinter joint models of virtual interconnect microstructures via simulations that analyze sinter joint model properties include defining a plurality of sinter joint objects in a virtual interconnect microstructure, each sinter joint object having a type and a size, and determining a location of individual sinter joint objects with respect to one another in a virtual joint space to create a sinter joint model. The type is at least one of an intermetallic compound, a void, and a metal particle. The location is determined by, for each object, creating three-dimensional coordinates, and based on a determination that the sinter joint object is spaced from and non-overlapping with previously placed sinter joint objects, locking a position and size of the sinter joint object.

Physical superconducting qubits are controlled according to an encoded qubit scheme, where a pair of physical superconducting qubits constitute an encoded qubit that can be controlled without the use of a microwave signal. For example, a quantum computing system has at least one encoded qubit and a controller. Each encoded qubit has a pair of physical superconducting qubits capable of being selectively coupled together. Each physical qubit has a respective tunable frequency. The controller controls a state of each of the pair of physical qubits to perform a quantum computation without using microwave control signals. Rather, the controller uses DC-based voltage or flux pulses.

A method is provided of targeted genome editing of an animal using site specific homologous integration. A composition comprising a single stranded oligonucleotide or double stranded nucleic acid molecule comprising a nucleic acid molecule of interest and sequences flanking a target locus cleavage site is injected into the zygote of an animal along with a nuclease and a guide nucleic acid molecule that targets the nuclease to a target locus. The composition is injected into the zygote after fertilization and prior to formation of a nucleus. The nucleic acid molecule of interest is recombined into the genome with high efficiency. The process allows for integration of nucleic acid molecules into the genome of animals in which the pronuclei cannot be visually observed during injection.

ConspectusThis Account focuses on stimuli responsive systems that function in aqueous solution using examples drawn from the work of the Isaacs group using cucurbit[n]uril (CB[n]) molecular containers as key recognition elements. Our entry into the area of stimuli responsive systems began with the preparation of glycoluril derived molecular clips that efficiently distinguish between self and nonself by H-bonds and π-π interactions even within complex mixtures and therefore undergo self-sorting. We concluded that the selectivity of a wide variety of H-bonded supramolecular assemblies was higher than previously appreciated and that self-sorting is not exceptional behavior. This lead us to examine self-sorting within the context of CB[n] host-guest chemistry in water.We discovered that CB[n] homologues (CB[7] and CB[8]) display remarkably high binding affinity (Ka up to 1017 M-1) and selectivity toward their guests, which renders CB[n]s prime components for the construction of stimuli responsive host-guest systems. The CB[7] ·adamantaneammonium ion complex, which is particularly privileged (K a = 4.2 × 1012 M-1), was introduced by us as a stimulus to trigger constitutional changes in multicomponent self-sorting systems. For example, we describe how the free energy associated with the formation of host-guest complexes of CB[n]-type receptors can drive conformational changes of included guests like triazene-arylene foldamers and cationic calix[4]arenes, as well as induced conformational changes (e.g., ammonium guest size dependent homotropic allostery, metal ion triggered folding, and heterochiral dimerization) of the hosts themselves.Many guests display large pKa shifts within their CB[n]-guest complexes, which we used to promote pH controlled guest swapping and thermal trans-to-cis isomerization of azobenzene derivatives. We also used the high affinity and selectivity of CB[7] toward its guests to outcompete an enzyme (bovine carbonic anhydrase) for a two-faced inhibitor, which allowed stimuli responsive regulation of enzymatic activity. These results prompted us to examine the use of CB[n]-type receptors in both in vitro and in vivo biological systems. We demonstrated that adamantaneammonium ion can be used to intracellularly sequester CB[7] from gold nanoparticles passivated with hexanediammonium ion·CB[7] complexes and thereby trigger cytotoxicity. CB[7] derivatives bearing a biotin targeting group enhance the cytotoxicity of encapsulated oxaliplatin toward L1210FR cells. Finally, acyclic CB[n]-type receptors function as solubilizing excipients for insoluble drugs for drug delivery purposes and as a broad spectrum reversal agent for the neuromuscular blocking agents rocuronium, vecuronium, and cis-atracurium in rats. The work highlights the great potential for integration of CB[n]-type receptors with biological systems. © 2014 American Chemical Society.
