Abstract: Systems and methods are described for modeling and analyzing utility structures according to applied loads. Particularly, a model engine can utilize inputs related to a utility structure, environmental conditions to which the utility structure is subjected, and engineering standards expected of the utility structure, and analyze the structure's loading and performance based on analysis configuration inputs. An engine or multiple engines can be run locally, or can be instantiated in a cloud to assist with multiple or complex calculations. Hybrid and geometric non-linear analyses and outputs can be performed or provided.

Abstract: A mascot retraction mechanism has a support (6) movably mounted to a track (5) for movement between a mascot deployed position and a mascot stowed position. A drive mechanism (7, 34, 35) may be arranged to drive the support along the track via a releasable latch (30). The releasable latch may be released by tilting of a mascot able to enable the support to move along the track free of the drive mechanism.

Abstract: A rack system for a vehicle includes a first rack member rotatably coupled to a support element in a cargo bed of the vehicle, a second rack member rotatably coupled to the first rack member, and a third rack member coupled to first rack member so as to be rotatable with respect to the first rack member independently of the second rack member. The rack members may be stowed when not in use, and deployed when the vehicle is stationary to enable various accessories to be mounted from the rack members. This enables the accessories to be spatially arranged for use according to user preferences and convenience.

Abstract: Improved methods for the production of reassortant influenza viruses are provided.

Abstract: Vaccine compositions useful for vaccination against a target influenza strain, and method and kits for using the same. The vaccines comprise a live attenuated influenza virus that is synthetically constructed based upon a backbone platform derived from a bat influenza strain, and heterologous surface proteins HA and NA derived from the target influenza strain. The live attenuated virus is non-reassortant with native, circulating influenza strains, and can be used to create vaccines for humans and other animals.
