In the title compound, C(19)H(11)NO(3), the isoindolinone ring system is approximately planar with a maximum atomic deviation of 0.071 (1) Å and the five-membered ring of the dihydro-benzo[g]indol-3-one unit assumes an envelope conformation. The naphthalene ring system makes a dihedral angle of 39.47 (4)° with the mean plane of the isoindolinone system. Inter-molecular O-H⋯O and C-H⋯O hydrogen bonding helps to stabilize the crystal structure.

A characteristic feature of redundancy in the motor system is the ability to compensate for the failure of individual motor elements without affecting task performance. In this study, we examined the pattern and variability in error compensation between motor elements during a virtual task. Participants performed a redundant cursor control task with finger movements.

Background: In their care of terminally ill patients, palliative care physicians and oncologists are increasingly predisposed to physical and emotional exhaustion, or compassion fatigue (CF). Challenges faced by physicians include complex care needs; changing practice demands, and sociocultural contextual factors. Efforts to better understand CF have, however, been limited.

N-acyl l-homoserine lactones are signaling molecules used by numerous bacteria in quorum sensing. Some bacteria encode lactonases, which can inactivate these signals. Lactonases were reported to inhibit quorum sensing-dependent phenotypes, including virulence and biofilm.

This research presents the design and analysis of a compact metamaterial (MTM)-based star-shaped split-ring resonator (SRR) enclosed in a square, constructed on a cost-effective substrate for liquid chemical sensing applications. The designed structure has dimensions of 10 × 10 mm and is optimized for detecting adulteration in edible oils. When the sample holder is filled with different percentages of oil samples, the resonance frequency of the MTM-based SRR sensor shift significantly.

Rice-crab co-culture is an environmentally friendly agricultural and aquaculture technology with high economic and ecological value. In order to clarify the structure and function of soil and water microbial communities in the rice-crab symbiosis system, the standard rice-crab field with a ring groove was used as the research object. High-throughput sequencing was performed with rice field water samples to analyze the species and abundance differences of soil bacteria and fungi.
