Abstract: Disclosed herein is a context-adaptive entropy model for end-to-end optimized image compression. The entropy model exploits two types of contexts. The two types of contexts are a bit-consuming context and a bit-free context, respectively, and these contexts are classified depending on the corresponding context requires the allocation of additional bits. Based on these contexts, the entropy model may more accurately estimate the distribution of each latent representation using a more generalized form of entropy models, thus improving compression performance.

Abstract: The present invention relates to a method for preparing a mutant strain having high producibility of phytoene and a mutant strain prepared thereby. More particularly, a Deinococcus radiodurans mutant strain, prepared by the method of the present invention, having high producibility of phytoene, does not retain an artificial antibiotic-resistant gene, although constructed by introducing a metabolism engineering method, and has high producibility of phytoene. Thus, the mutant strain prepared according to the method can find useful applications in the mass production of phytoene.

Abstract: Various embodiments of the present application are directed towards an integrated memory chip comprising a memory array with a strap-cell architecture that reduces the number of distinct strap-cell types and that reduces strap-line density. In some embodiments, the memory array is limited to three distinct types of strap cells: a source line/erase gate (SLEG) strap cell; a control gate/word line (CGWL) strap cell; and a word-line strap cell. The small number of distinct strap-cell types simplifies design of the memory array and further simplifies design of a corresponding interconnect structure. Further, in some embodiments, the three distinct strap-cell types electrically couple word lines, erase gates, and control gates to corresponding strap lines in different metallization layers of an interconnect structure. By spreading the strap lines amongst different metallization layers, strap-line density is reduced.
