Protic NHC Iridium Complexes with beta-H Reactivity-Synthesis, Acetonitrile Insertion, and Oxidative Self-Activation
'American Chemical Society (ACS)', 2019Co-Authors: Rong, Mark K., Chirila Andrei, Franciolus David, Lutz Martin, Nieger Martin, Ehlers, Andreas W., Slootweg J. Chris, Lammertsma KoopAbstract:Protic NHC iridium complexes, obtained from the corresponding azido-phenylene-isocyanide precursor complexes, were investigated for ligand-based reactivity. Under redox-neutral conditions, acetonitrile inserts into the N-H bonds to provide kappa(2)-NHC-imidoyl ligand-based complexes, while under reductive conditions the complex also Expels one N-H proton to provide the corresponding deprotonated analogues. Using zinc as a reductor activates the NHC-iridium complex to form an asymmetric bimetallic iridium hydrido complex, in which two anionic N-deprotonated NHCs bridge the bimetallic core. X-ray crystal structures are reported for the azido-phenylene-isocyanide precursor complex, the protic NHC complex, and the asymmetric bimetallic iridium hydride complex. Density functional computations and a QTAIM analysis of the bimetallic iridium hydrido complex are provided.Peer reviewe

Optimizing the decision to expel attackers from an information system
2009 47th Annual Allerton Conference on Communication Control and Computing (Allerton), 2009Co-Authors: Ning Bao, John MusacchioAbstract:The conventional reaction after detecting an attacker in an information system is to expel the attacker immediately. However the attacker is likely to attempt to reenter the system, and if the attacker succeeds in reentering, it might take some time for the defender's intrusion detection system (IDS) to re-detect the attacker's presence. In this interaction, both the attacker and defender are learning about each other — their vulnerabilities, intentions, and methods. Moreover, during periods when the attacker has reentered the system undetected, he is likely learning faster than the defender. The more the attacker learns, the greater the chance that he succeeds in his objective — whether it be stealing information, inserting malware, or some other objective. Conversely, the greater the defender's knowledge, the more likely that the defender can prevent the attacker from succeeding. In this setting, we study the defender's optimal strategy for expelling or not expelling an intruder. We find that the policy of always expelling the attacker can be far from optimal. Furthermore, by formulating the problem as a Markov decision process (MDP), we find how the optimal decision depends on the state variables and model parameters that characterize the IDS's detection rate and the attacker's persistence.

Politik Seksual dalam Tafsir al-Qur'an tentang Sejarah Homoseksualitas
'Al-Jamiah Research Centre', 2018Co-Authors: Luthfillah, Muhammad Dluha, Khalil, Muhammad Imdad IlhamiAbstract:Homophobic bias has been existing in tafsir literature, ranging from its very early works to the most recent ones. Among the aspects in which such a bias appears is that relating to the history of homosexuality. Al-A’rāf ([7]: 80) and al-‘Ankabūt ([29]: 28) are the only verses that talk about the aspect. Rather than following the mainstream tafsir denying the historicity of homosexuality, this article elaborates al-Rāzī’s alternative interpretation on the two verses and comes up with an argument that homosexuality might historically exist even before the lifetime of Lot and his people. Emphasizing on linguistic and literary analysis on the words sabaqa, bi, and fahisya, it finds strong foundations on which the argument is relying. Further, the article finds that it is the sexual politics that brings about the homophobic bias into Qur’an tafsir. The very kind of politics Expels homosexuality from the so- called ‘normal’ life
