Efficient processing of tera-scale text data is an important research topic. This paper proposes lossless compression of N gram language models based on LOUDS, a succinct data structure. LOUDS succinctly represents a trie with M nodes as a 2M + 1 bit string. We compress it further for the N -gram language model structure. We also use ‘variable length coding’ and ‘block-wise compression’ to comp...

Although metal–organic framework (MOF) photocatalysts have become ubiquitous, basic aspects of their photoredox mechanisms remain elusive.

Abstract Transversely curved composite shells of liquid crystal elastomer and polyethylene terephthalate with innervated electrodes present millisecond‐scale actuation ≈200 mW electrical power inputs at low voltages (≈1 V). The molecular orientation is aligned to direct the thermomechanical work‐content evert native curvature. When powered, structure initially remains latent builds up strain en...
