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
