Abstract: A narrow bandpass filter that may be used in a mid-infrared sensor for monitoring a species, which may be a component of a fluid or a solid material. The filter comprises a cavity comprising a low refractive index material. By providing a high ratio of low refractive index material in the filter with respective to high refractive index material, the filter is configured so that wavelength transmission remains constant with varying temperature. Materials used for the low and/or high refractive index provide a temperature invariant filter that transmits mid-infrared spectra without serious degradation.

Abstract: The methods and compositions provided herein improve upon the methods presently used for targeted genomic modification, in part, by removing the requirement for sub-cloning of a sequence complementary to a site selected for genomic modification. The methods and compositions provided herein can be used in place of a standard CRISPR/Cas system to provide simple, fast, and inexpensive targeted modification of a genome. The methods and compositions provided herein can also be used in high-throughput genome editing applications.

Abstract: Systems, methods, and non-transitory computer-readable media can generate subscription information associated with a user and a content item, wherein the subscription information is indicative of the user viewing the content item. The subscription information is stored at a first data center. A determination is made to replicate the subscription information based on replication criteria. The subscription information is replicated to one or more additional data centers based on the making the determination to replicate the subscription information.

Abstract: The present invention provides an efficient secure end-to-end messaging system utilizing encrypted ephemeral messages. The method comprises the steps of using a combination of HTTPS for transport security, using symmetric key cryptography with rotating temporary keys for individual message security, and using elliptic curve cryptography for key derivation and message authentication. The key rotation scheme used provides forward secrecy between messages and sessions.

The method comprises the steps of using a combination of HTTPS for transport security, using symmetric key cryptography with rotating temporary keys for individual message security, and using elliptic curve cryptography for key derivation and message authentication. The key rotation scheme used provides forward secrecy even between messages and perfect forward secrecy between sessions.

Abstract: An apparatus includes a first retail display unit for supporting one or more retail products and a pocket mounted to a side of the first retail display unit. The pocket has a hollow interior and an open end. A gate has a fixed end coupled to the hollow interior of the pocket and a lockable end. The fixed and lockable ends of the gate are located within the hollow interior of the pocket when the gate is in storage and the lockable end of the gate is extended through the at least one open end of the pocket and away from the first retail display unit when the gate is moved into use.

Abstract: Populations enriched for myogenic progenitors are obtained by selection on the basis of expression of specific cell surface markers. The muscle progenitor cells are characterized as being CD45? and CD34+, and may further be characterized as lacking expression of Mac-1 (CD11b) and positive for expression of CXCR4 (CD184) and ?1-integrin (CD29).

Abstract: The apparatus includes two side members each having a plurality of spaced apart slats formed on its inner side with adjacent slats forming a slot. The side members have upper edges which slant upward and rearward from the upper ends of their front edges. Each rearward of an adjacent slat has its top and bottom edges located at a level above the top and bottom edges respectively of the adjacent slat. The side members are supported such that their slats face each other and are spaced from each other to form a flooring sample receiving space. A floor is coupled between the two side members at the bottom edges of the slats. Each slot of one side member is aligned with a slot of the other side member to form a plurality of pairs of slots with each pair of slots and the floor being adapted to support a flooring sample. Each of the side members and its slats are formed as an integral member molded from plastic material.

Abstract: A product dispensing apparatus includes a support having a tray system supported thereon and the tray system includes front and rear walls interconnected by side walls and having a plurality of adjustable partitions extending between the front and rear walls to produce side-by-side trays. A guide member is located in each tray and slidably supports a pusher member which is biased toward the front wall. The support defines a stop to move all of the pusher members toward the rear wall when the tray system is moved from a product dispensing position to a product restocking position on the support.

Abstract: A dispensing unit includes a tray system including front, rear and side walls with partitions dividing the system into a plurality of trays and a support slidably supporting the tray system between a product dispensing position and a product restocking position. Each tray has a slot in its bottom between the front and rear walls with a pusher plate slidably supported in the slot and biased toward the front wall. The support has a stop which moves all of the pusher plates toward the rear wall when the tray system is moved to the restocking position and a latch mechanism holds the tray in the product dispensing position.
