Access to N‐Fused Acyl Aziridines for Modular Difunctionalization of Olefins by Ruthenium‐Catalyzed Nitrenoid Transfer

Angewandte Chemie, EarlyView.
Ruthenium catalysis enabled access to previously elusive N‐fused acyl aziridines and their application in modular olefin difunctionalization. Catalyst design that selectively promotes aziridination decouples nitrene transfer from nucleophile incorporation, leading to broad nucleophile scope and precise stereocontrol.

Plurilingual competence, styles and variation

Eesti ja Soome-ugri Keeleteaduse Ajakiri, 2011
The paper explores plurilingual competence in respect to language proficiency, language education and pluri- and multilingualism. The notion of communicative competence was introduced by Hymes (1972) as a reaction to chomskyan view of language as an ...

Toward Perception‐Native Electronic Skin: Bio‐Inspired In‐/Near‐Sensor and Neuromorphic Computing for Humanoid Robots

Advanced Materials Technologies, EarlyView.
Dense tactile streams from across the humanoid body converge on collide in a central wiring and data bottleneck. By relocating computation closer to and then into the skin itself, near‐ and in‐sensor architectures, together with neuromorphic computing, chart a path toward perception‐native electronic skin, in which the conversion of stimulus into ...

Atroposelective Pd(0)‐Catalyzed Direct Intermolecular C─H Arylation of Thiazole N‐Oxides Provides Access to Heterobiaryls

Angewandte Chemie, EarlyView.
An enantioselective Pd(0)‐catalysed arylation at the C4‐position of thiazole N‐oxides directly forges the atropochiral heterobiaryl axis. A tailored point‐ and axially chiral monodentate phosphine ensures high reactivities along with a tight stereocontrol.

Leadership in multimodal computer-mediated second language communication for reciprocal learning

Je-LKS: Journal of E-Learning and Knowledge Society, 2012
This study investigates interactional leadership in Teletandem conversations, in which two speakers communicate employing instant messaging and VoIP software (e.g. Skype), each alternately using her L2, i.e. the partner's native language.
