  • Patent number: 11981885
    Abstract: A cell cultivation apparatus for cultivating microorganisms and growing cells at high density is provided. The apparatus includes a membrane comprising multiple surface features on a first side of the membrane for cell placement. The surface features comprising one or more compartments within which a cell can be located. The membrane includes a material that is at least partially permeable to gas. A second side of the membrane defines a gas region. The second side of the membrane is separated from the first side of the membrane by the membrane. The apparatus further includes a media region for receiving media. The compartments are configured to at least partially reduce media flow shear forces on one or more cells in the compartments.

  • Patent number: 11702453
    Abstract: The disclosure provides materials in the form of flavivirus variants that each encode a Non-Structural Protein-1 (NS1) variant, wherein the coding region is a chimera of at least two different NS1 coding regions, or wherein the coding region has at least one mutation in a codon of a canonical Asn-Xxx-Ser/Thr N-linked glycosylation site, wherein Asn is asparagine, Xxx is any amino acid, and Ser/Thr is either serine or threonine, or wherein the coding region is both a chimera and has at least one mutation in a codon of a canonical N-liked glycosylation site, wherein Asn is asparagine, Xxx is any amino acid, and Ser/Thr is either serine or threonine. The disclosure also provides methods of using such flavivirus variants to inhibit the transmission of infectious flavivirus.

  • Patent number: 9797015
    Abstract: Described herein is a method of determining lithium responsiveness in a bipolar disorder patient. The method includes obtaining a sample from a patient having bipolar disorder, and assaying the sample for the presence or absence of one or more glutamate decarboxylase-like 1 (GADL1) gene variants selected from the group consisting of a T allele of the single nucleotide polymorphism (SNP) rs17026688, a G allele of the SNP rs17026651, and GADL1 1VS8+48delG. The presence of one or more of the GADL1 gene variants indicates that the patient is responsive to lithium treatment.

  • Patent number: 9450893
    Abstract: Systems and methods are described for providing network route redundancy through Layer 2 devices, such as a loop free Layer 2 network having a plurality of switching devices. A virtual switch is coupled to the loop free Layer 2 network, the virtual switch having two or more switches configured to transition between master and backup modes to provide redundant support for the loop free Layer 2 network, the switches communicating their status through use of a plurality of redundancy control packets. The system also includes means for allowing the redundancy control packets to be flooded through the Layer 2 network. The means may include time-to-live data attached to the redundancy control packet which is decremented only when the packets are transferred through devices which are configured to recognize the protocol used in redundancy control packets.

  • Patent number: 9391888
    Abstract: The system, method, and article of manufacture of the present invention allows multiple customers connected to a common external network to each implement a layer 2 redundancy protocol, such as the spanning tree protocol, in order to prevent layer 2 loops. Accordingly, a method is presented for providing an independent loop free layer 2 topology between a external network and a customer network comprising tagging control packets originating on the customer network with a unique identifier and tunneling the control packets received from the customer network between a plurality of boundary interface devices at the external network such that the control packets are routed back to the customer network based on the presence of the unique identifier in the control packet. The layer 2 redundancy protocol on the customer network converges based at least in part on the presence of control packets appearing on more than one port on the customer network.

  • Patent number: 6717922
    Abstract: A network configuration protocol and algorithm are described which resolve deficiencies with existing protocols. A large network having many bridges may be built as a combination of smaller networks, many of which may each be arranged in a ring topology. Each ring may be monitored by a single master bridge regularly sending control packets, and each other bridge in the ring does not make decisions with respect to its status. A loop free topology is achieved by selectively blocking and unblocking data traffic in one of the ring ports of the single master bridge for the ring, while all other bridges in the ring keep their ports in non-blocked states. In multiple ring topologies, each ring has a single master bridge which chooses one of its ports to be blocking.
