Abstract While improving neural dialogue agents’ factual accuracy is the object of much research, another important aspect communication, less studied in setting dialogue, transparency about ignorance. In this work, we analyze to what extent state-of-the-art chit-chat models are linguistically calibrated sense that their verbalized expression doubt (or confidence) matches likelihood model’s res...

The major part of the DNA from polyoma virus has been shown to consist of circular base-paired duplex molecules without chain ends.' -' The intertwined circular form accounts for the ease of renaturation4 of this DNA and the failure of the strands to separate in strand-separating solvents. I-' In previous studiesl-3 a minor component, II, observed in variable amounts in sedimentation analyses o...

The effect of pressure, stand-off distance and time on the penetration of sandstones by a 0.84 mm. jet of water was investigated. Pressures ranged up to 9000 lb/in 2 (62 MN/M), stand-off distances to 2 in. (5.08 cm) and time from 0.5 to 30 sec. The effect of using a friction reducing agent was determined. The advantages of allowing the spent jet to escape and not interfere with penetration are ...

Reducing agents-Enhanced electrokinetic Soil Remediation (EKSR) was performed for the removal of chromium (Cr), cobalt (Co) and nickel (Ni) from contaminated soil. The reducing agents oxalic acid and ascorbic acid were investigated under constant voltage gradient (2.0 V/cm), current changes, pH, redox potential, concentration changes and removal performance of Heavy Metals (HMs). The result...

The rhombohedral-like CuFeO(2) crystals are synthesized via a facile hydrothermal route by using propionaldehyde as a reducing agent. The obtained CuFeO(2) crystals show promising efficiency in the inactivation of bacteriophage Qβ.

We review fluorescent probes that can be photoswitched or photoactivated and are suited for single-molecule localization based super-resolution microscopy. We exploit the underlying photochemical mechanisms that allow photoswitching of many synthetic organic fluorophores in the presence of reducing agents, and study the impact of these on the photoswitching properties of various photoactivatabl...
