XHate-999: Analyzing and Detecting Abusive Language Across Domains and Languages

International Conference on Computational Linguistics, 2020
We present XHate-999, a multi-domain and multilingual evaluation data set for abusive language detection. By aligning test instances across six typologically diverse languages, XHate-999 for the first time allows for disentanglement of the domain ...

Usefulness of PET With [18F]LBT-999 for the Evaluation of Presynaptic Dopaminergic Neuronal Loss in a Clinical Environment

Frontiers in Neurology, 2020
Purpose: The density of the neuronal dopamine transporter (DAT) is directly correlated with the presynaptic dopaminergic system injury. In a first study, we evaluated the brain distribution and kinetics of [18F]LBT-999, a DAT PET radioligand, in a group ...

Research on Mesoscale Nucleation and Growth Processes in Solution Crystallization: A Review

Crystals, 2022
In recent studies, the existence of mesoscale precursors has been confirmed in crystallization. Different from the classical crystallization theory, which only considers the sequential attachment of basic monomers (atoms, ions, or molecules), the ...

How Do the Surroundings of the C-NO₂ Fragment Affect the Mechanical Sensitivity of Trinitroaromatic Molecules? Evidence from Crystal Structures and Ab Initio Calculations

Crystals
The dissociation of the C-NO2 bond is the initial step in the process of the detonation of nitroaromatic explosives. The strength of the C-NO2 bond is significantly influenced by the relative position of the nitro group with respect to the aromatic ring ...

Reaction-Time-Dependent Opto-Electrical Properties of Graphene Oxide

Crystals, 2022
The reaction-time-dependent synthesis of graphene oxide (GO) was carried out using a modified Hummer’s method. The drop-casting method was used to coat GO films on a glass substrate.
