Semigroup presentation for congruences on groups
(KOREAN MATHEMATICAL SOC, 2013)We consider a congruence rho on a group G as a subsemigroup of the direct product G x G. It is well known that a relation rho on G is a congruence if and only if there exists a normal subgroup N of G such that rho = {(s, ... -
Set similarity modulates object tracking in dynamic environments
(SPRINGER, 2018)Based on the observation that sports teams rely on colored jerseys to define group membership, we examined how grouping by similarity affected observers' abilities to track a ball target passed between 20 colored circle ... -
Short- and long-term forms of neural adaptation: An ERP investigation of dynamic motion aftereffects
(ELSEVIER MASSON,, 2020)Adaptation is essential to interact with a dynamic and changing environment, and can be observed on different timescales. Previous studies on a motion paradigm called dynamic motion aftereffect (dMAE) showed that neural ... -

Single-electron transmetalation: An enabling technology for secondary alkylboron cross-coupling
(AMER CHEMICAL SOC, 2015)Single-electron-mediated alkyl transfer affords a novel mechanism for transmetalation, enabling cross-coupling under mild conditions. Here, general conditions are reported for cross-coupling of secondary alkyltrifluoroborates ... -
Site Identity and Importance in Cosubstituted Bixbyite In2O3
(MDPI., 2017)The bixbyite structure of In2O3 has two nonequivalent, 6-coordinate cation sites and, when Sn is doped into In2O3, the Sn prefers the b-site and produces a highly conductive material. When divalent/tetravalent cation pairs ... -
