Abstract: The exemplified methods and systems provides deep neural network configured with a deep compositional grammatical architecture (e.g., to facilitate end-to-end representation learning). The instant deep compositional grammatical architecture beneficially integrates the compositionality and reconfigurability of grammar models with the capability of learning rich features of the deep neural networks in a principled way (e.g., for a convolutional neural network or a recombinant neural network). The instant deep compositional grammatical architecture utilizes AND-OR grammars to form an AND-OR grammar network.

Abstract: Triterpenoid drugs such as CDDO-Me can be used as to treat autoimmune diseases such as graft versus host disease, lupus, and lupus nephritis. Triterpenoid drugs can also be used to prevent the effects of an autoimmune disease.

Abstract: An energy regeneration type forklift hydraulic system is provided, which includes a first oil pump, a first electrical motor, a multiple directional control valve, a lifting oil cylinder, a tilting oil cylinder, a steering oil cylinder, a load-sensing steering device, an oil filter, a second oil pump and an oil tank, wherein the multiple directional control valve includes an oil inletting and returning valve spool, a raising and lowering reversing valve spool, a tilting reversing valve spool, and an oil inletting valve spool. The raising and lowering reversing valve spool includes a raising and lowering three-position six-way reversing valve, an annular oil returning passage and an oil returning passage. The system can utilize the potential energy of lowering cargo to simultaneously drive two oil pumps for driving two motors to generate energy, thereby realizing energy recovery.
