Abstract: Disclosed are compositions and methods for culturing cells in a manner that inhibits culture induced senescence. In one aspect, the methods comprise the administration of nicotinamide adenine dinucleotide (NAD) precursors to the culture. Further disclosed are NAD precursors used in the methods, comprising nicotinamide (NAM), nicotinamide mononucleotide (NMN), and/or nicotinamide riboside (NR).

Abstract: Deployable barriers are reversibly deployed in a data center hall to partition the data center. The hall is partitioned into an operational area, where rack computer systems are installed, a non-operational area, and a staging area where support infrastructure is at least partially installed. A barrier can be collapsed to incorporate the staging area into the operational area, thereby expanding the operational area, when rack computer systems are to be installed in the staging area. A barrier deployed in the non-operational area establishes another staging area. A barrier includes a deployment mechanism which extends through a space in the data center to enable a partition to be extended to partition the hall. The barrier can be mounted and deployed on support infrastructure, so that the deployed barrier and a side portion of the support infrastructure collectively partition the hall.

Abstract: A method and system for authenticating and validating electronic architectural documents. A document approved by a licensed architect has the architects digital seal and signature associated with or inserted into the document file. A hash function is performed to create an issued file with the digital seal and signature and a cryptographic hash. The issued document is distributed to a recipient, extracted to a local drive, and subsequently accessed for use in an architectural project. The cryptographic hash of the extracted file is compared to that of the accessed filed to determine if they are the same. If the same, the accessed document is validated and the digital seal and signature remain visible in the accessed document. If not, the accessed document is not validated and the digital seal and signature are removed from or hidden, indicating the document should not be used.

Abstract: An inverted exhaust plenum module exhausts air from an enclosure into an ambient environment while mitigating airflow restrictions caused by ambient wind conditions, particularly headwinds impinging on exhaust vents. The plenum module includes wall elements that extend downwards from separate edges of two separate roof elements of the enclosure, forming a plenum between the wall elements that is open at the top. Exhaust vents in the wall elements exhaust air from the enclosure into the plenum to circulate into the ambient environment via the top of the plenum. By exhausting air into a plenum that extends beneath roof elements, the vents are at least partially obscured from ambient winds that might otherwise impinge on the vents. A wing element can be installed to induce exhaust airflow via lowering air pressure at the top of the plenum. The plenum module can be a separate module that is coupled to a structure.

Abstract: A fan assembly comprises a fan and a movable fan support. The fan has a motor and a fan blade drivable by the motor to move air in an airflow direction through an opening. The movable fan support is configured to movably support at least the fan. The fan support is mountable adjacent the opening on a first side and comprises extension members extendable from an operating position on the first side of the opening to an access position on a second side of the opening opposite the first side. In the access position, the extension members extend through the opening from the first side to the second side to support the motor and fan blade on the second of the opening for access.
