Unlocking Tertiary Acids for Metallaphotoredox C(sp2)–C(sp3) Decarboxylative Cross-Couplings
, 2023 Dual nickel photoredox catalysis conditions have been developed for the decarboxylative cross-coupling of aryl halides and carboxylic acids containing fully substituted α-carbons, a valuable but challenging substrate class for C(sp2)–C(sp3) bond-forming ...

Coupling evaluators for attribute coupled grammars [PDF]
, 1994 Some years ago, the notion of attribute coupled grammars was introduced by Ganzinger and Giegerich [4], together with descriptional composition. The latter works essentially at the specification level, i.e., it produces an attribute grammar which specifies the composition of two attribute coupled grammars.

Coupling strength versus coupling impact in nonidentical bidirectionally coupled dynamics [PDF]
Physical Review E, 2017 The understanding of interacting dynamics is important for the characterization of real-world networks. In general, real-world networks are heterogeneous in the sense that each node of the network is a dynamics with different properties. For coupled nonidentical dynamics symmetric interactions are not straightforwardly defined from the coupling ...

Non-derivative axionic couplings to nucleons at large and small N
Journal of High Energy Physics, 2020 Among the possible CP-odd couplings of the axion to ordinary matter, the most relevant ones for phenomenology are the Yukawa couplings to nucleons. We analyze such non-derivative couplings within three different approaches: standard effective field ...

On NS-NS couplings at order α′3
Nuclear Physics B, 2021 Recently, imposing the gauge-symmetry and the T-duality constraints on the string frame effective actions of type II superstring theories at order α′3, the NS-NS couplings have been found in a particular scheme which has 445 couplings in 15 different ...

Structural characterization of the leukemia drug target ABL kinase and unfolded polypeptides by novel solution NMR techniques [PDF]
, 2010 Novel weak alignment techniques and new biochemical strategies like selective isotope labeling in combination with other high-resolution solution NMR methods have been applied to characterize folded and unfolded polypeptides.

Information and Computation, 2015 In this paper, some general properties of Shannon information measures are investigated over sets of probability distributions with restricted marginals. Certain optimization problems associated with these functionals are shown to be NP-hard, and their special cases are found to be essentially information-theoretic restatements of well-known ...
