A Direct Measurement of the Absolute Energies of Protonated Gly‐Pro‐Gly‐Gly Conformations Using Ion Mobility Spectrometry and Guided Ion Beam Tandem Mass Spectrometry

open access: yesChemPhysChem, EarlyView.
Relative energies of the cis and trans conformers of the protonated tetrapeptide, Gly‐Pro‐Gly‐Gly, selected by ion mobility spectrometry are measured using threshold collision‐induced dissociation. The trans conformation was found to be more stable than the cis conformation by 4.5 ± 2.5 kJ mol−1 at 0 K, a value in agreement with several levels of ...

High-rate, Multi-Symbol-Decodable STBCs from Clifford Algebras [PDF]

open access: yesarXiv, 2007
It is well known that Space-Time Block Codes (STBCs) obtained from Orthogonal Designs (ODs) are single-symbol-decodable (SSD) and from Quasi-Orthogonal Designs (QODs) are double-symbol decodable. However, there are SSD codes that are not obtainable from ODs and DSD codes that are not obtainable from QODs.

AI and the Future of Disputing: Naming, Blaming, Claiming, and Preventing

open access: yesConflict Resolution Quarterly, EarlyView.
ABSTRACT This paper explores the transformative impact of artificial intelligence (AI) on dispute resolution mechanisms. Our analysis builds on the longstanding framework for explaining the stages through which disputes evolve: the “naming, blaming, claiming” model by Felstiner, Abel, and Sarat (1981).
