Nonlinear approximation via compositions.
Shen Z, Yang H, Zhang S. Shen Z, et al. Neural Netw. 2019 Nov;119:74-84. doi: 10.1016/j.neunet.2019.07.011. Epub 2019 Aug 2. Neural Netw. 2019. PMID: 31401528
In particular, for any function f on [0,1], regardless of its smoothness and even the continuity, if f can be approximated using a dictionary when L=1 with the best N-term approximation rate epsilon(L,f)=O(N(-eta)), we show that dictionaries wit …

4-Bromo-1-[2,6-dichloro-4-(trifluoro-meth-yl)phen-yl]-5-(4-nitro-benzyl-idene-amino)-1H-pyrazole-3-carbonitrile.
Yang Z, Li S. Yang Z, et al. Acta Crystallogr Sect E Struct Rep Online. 2008 Feb 29;64(Pt 3):o645. doi: 10.1107/S160053680800545X. Acta Crystallogr Sect E Struct Rep Online. 2008. PMID: 21201975 Free PMC article.
The title compound, C(18)H(7)BrCl(2)F(3)N(5)O(2), is an L-shaped tricyclic imine. The pyrazole ring is essentially coplanar with the nitro-substituted benzene ring [dihedral angle = 3.6 (2)] and approximately perpendicular to the trifluoro-methyl-substituted ring [d …
