Selective Sequestration of Toxic NOx Gases by P‐Doped Graphene: A Density Functional Theory Study
Advanced Physics Research, EarlyView.P‐doped graphene (P‐grap) is explored as an NOx sensor through DFT simulations. The analysis of its geometry, binding energies, electronic properties, and atom‐in‐molecule characteristics demonstrates that P‐grap is a selective sensor for NOx among a mixture of various gases.

Long-distance frequency transfer over an urban fiber link using optical phase stabilization
, 2008 We transferred the frequency of an ultra-stable laser over 86 km of urban fiber. The link is composed of two cascaded 43-km fibers connecting two laboratories, LNE-SYRTE and LPL in Paris area.

Journal of the Association for Information Science and Technology, EarlyView.Abstract Aspect‐Based Sentiment Analysis (ABSA) has evolved from textual analysis to a multimodal paradigm, integrating visual information to capture nuanced sentiments. Despite advancements, existing Multimodal ABSA (MABSA) research remains limited in granularity, which focuses on either coarse‐level categories or named entities, neglecting fine ...

Evaluation of performance of acoustic materials - a case study in Brazilian civil construction
Archives of Acoustics, 2014 Urban noises are emitted simultaneously by a wide variety of sources, such as, transportation and activities encountered in large cities. Many studies show that traffic noise followed by noise produced by neighbours are the main disturbing sources ...
