Abstract: Described herein photonic interconnects based on glass interposers. Glass interposers of the types described herein are used to photonically interconnect multiple smaller photonic integrated circuits (PIC), as opposed to using a single, larger PIC. The typical yield of a glass interposer is significantly higher than the yield of a PIC. This is because glass interposers are passive in nature, while PICs include active photonic elements. Active photonic components (e.g., photonic transceivers and switches) tend to be more susceptible to manufacturing defects than passive photonic components (e.g., waveguides and couplers) because active components require additional manufacturing steps (e.g., ion implantation, sputtering, epitaxial growth, etc.). The approach described herein improves performance because instead of having to slice a large number of continuous reticles from a wafer, one can pick and choose reticles known to have yielded.

A plurality of electric lanes place the on-chip communication units of photonic tiles of different rows in electrical communication with one another. A plurality of photonic lanes place the on-chip communication units of photonic tiles of different columns in optical communication with one another.

Abstract: The present invention is a DNA expression vector comprising: a toxP: a mutant toxO that blocks Fe-mediated regulation of gene expression; and a DNA sequence encoding a protein, wherein the toxP and the mutant toxO regulate expression of the DNA segment encoding the protein. It is preferred that DNA expression vectors of the present invention include DNA sequences encoding a signal peptide so that a protein expressed is attached to the signal peptide prior to processing. Novel proteins are produced off of the DNA expression vector of the present invention.

Abstract: Cloud services intelligently provision new VMs for a VM scale set when the original label that included the OS or other software images used to provision existing VMs of the VM scale set is no longer available or has been changed. Metadata of the existing VMs are analyzed to identify an OS image or other software image used to provision the existing VMs. The metadata also reveals updates that are running on the new VMs. These updates include software that was not part of the original label used to provision the existing VMs and are used to find the second label in a label database. The second labels include the OS or software of the existing VMs—or a later version thereof—and some portion of the updates. A VM-provisioning service uses the second label to provision the new VM.
