6-Fluoro-1H-indole-3-carboxylic acid
In the title compound, C9H6FNO2, all the non-H atoms are approximately coplanar, the carboxy O atoms deviating by 0.0809 and −0.1279 Å from the indole plane. In the crystal, O—H⋯O hydrogen bonds link the molecules into dimers which are linked via N—H⋯O hydrogen bonds and π–π interactions [centroid–centroid distance = 3.680 (2) Å
Psychosocial Adjustment of Women with Work-related Disabilities in Rural China
The impact of gender roles on the psychosocial adjustment of women in rural China with work related disabilities is explored. The influence of economic reform, traditional family orientation, and gender expectations on the ability of women to work in rural China are discussed via three case studies
Computational Aspects of Optional P\'{o}lya Tree
Optional P\'{o}lya Tree (OPT) is a flexible non-parametric Bayesian model for
density estimation. Despite its merits, the computation for OPT inference is
challenging. In this paper we present time complexity analysis for OPT
inference and propose two algorithmic improvements. The first improvement,
named Limited-Lookahead Optional P\'{o}lya Tree (LL-OPT), aims at greatly
accelerate the computation for OPT inference. The second improvement modifies
the output of OPT or LL-OPT and produces a continuous piecewise linear density
estimate. We demonstrate the performance of these two improvements using
simulations
2-(6-Chloro-1H-indol-3-yl)acetonitrile
In the title compound, C10H7ClN2, the carbonitrile group is twisted away from the plane of the indole ring system [Ccy—Cme—Car—Car = −44.7 (8)°; cy = cyanide, me = methylene and ar = aromatic]. In the crystal, N—H⋯N hydrogen bonds link the molecules into C(7) chains propagating in [010]. Aromatic π–π stacking interactions [minimum centroid–centroid separation = 3.663 (3) Å] are also observed
2-(4-Chloro-1H-indol-3-yl)acetonitrile
The title compound, C10H7ClN2, contains two approximately planar molecules, A and B (r.m.s. deviations = 0.039 and 0.064 Å, respectively) in the asymmetric unit. In the crystal, N—H⋯N hydrogen bonds link the molecules into C(7) chains of alternating A and B molecules propagating along the a-axis direction. The crystal used for the data collection was found to be a racemic twin
