Eliminating unpredictable variation through iterated learning [PDF]

, 2010
Human languages may be shaped not only by the (individual psychological) processes of language acquisition, but also by population-level processes arising from repeated language learning and use.

Epigenetic blind spots – the role of DNA methylation dynamics in stem cell‐based models of embryogenesis

FEBS Letters, EarlyView.
Embryo‐like structures (stembryos) are an innovative tool, but they are hindered by experimental variability and limited developmental potential. DNA methylation is crucial for mammalian development, but its status in stembryo models is poorly characterized.

Macromedusae of Southern Brazil: temporal variation, population structure and biochemical composition

Brazilian Journal of Oceanography
The objectives of this study were to record the macromedusae species on the north coast of Santa Catarina, and to estimate their population dynamics and variations in their biochemical composition, based on the specimens obtained in the by-catch of ...

When synchrony meets diachrony : The negation system of Fɛʔfɛʔ in the light of the Jespersen Cycle

, 2015
This dissertation is concerned with synchronic variation as the reflection and residue of language change. The empirical focus is the negation system of Fɛʔfɛʔ.

pH‐mediated activation of the lysosomal arginine sensor SLC38A9

FEBS Letters, EarlyView.
Cells monitor nutrient levels via the lysosomal transporter SLC38A9 to activate the mechanistic target of rapamycin complex 1 (mTORC1). This study reveals that SLC38A9 function is regulated by pH. We identified histidine 544 as a critical pH sensor that undergoes conformational changes to control amino acid efflux from lysosomes; therefore, it ...

SIZE VARIATION AND SURFACE STRUCTURE OF PODS AND SEEDS OF BAUHINIA RACEMOSA LAMK.

FUUAST Journal of Biology, 2021
Size variation and surface structure of pods and seeds of Bauhinia racemosa are described. The immature and developing fruits of B. racemosa are twisted strap like dark green, and photosynthesizing. The mature fruits mostly twisted, oblong and compressed

Linguistic Variation and Change

, 2011
The study of variation and change is at the heart of the sociolinguistics. Providing a wide survey of the field, this textbook is organised around three constraints on variation: linguistic structure, social structure and identity, and social and ...

Strong domain variation and treebank-induced LFG resources [PDF]

, 2005
In this paper we present a number of experiments to test the portability of existing treebank induced LFG resources. We test the LFG parsing resources of Cahill et al. (2004) on the ATIS corpus which represents a considerably different domain to the Penn-
