Factors Affecting Grammatical and Lexical Complexity of Long-Term L2 Speakers’ Oral Proficiency [PDF]
, 2016 There remains considerable disagreement about which factors drive second language (L2) ultimate attainment. Age of onset (AO) appears to be a robust factor, lending support to theories of maturational constraints on L2 acquisition.

“Foreign” language aptitude predicts individual differences in native grammatical proficiency
Linguistics, 2023 Language aptitude is known to be a strong predictor of success in late second-language (L2) learning in instructional settings but is generally assumed to be irrelevant for native language (L1) acquisition.

Attaining the Ultimate Precision Limit in Quantum State Estimation [PDF]
Communications in Mathematical Physics, 2019 We derive a bound on the precision of state estimation for finite dimensional quantum systems and prove its attainability in the generic case where the spectrum is non-degenerate. Our results hold under an assumption called local asymptotic covariance, which is weaker than unbiasedness or local unbiasedness.
