Phonological assimilations add to the invariance problem. It is generally accepted that assimilated word forms are only recognized as an instance of the intended word in phonological contexts in which assimilation is allowed. We examined the mechanisms that drive this compensation for assimilation by presenting Hungarian morphologically complex words and non-words to Hungarian and Dutch listene...

Past research has shown that the speech processing system is, under certain circumstances, relatively tolerant to surface variations in connected speech. The goal of this study is to explore regressive voice assimilation in French, a surface variation in which the voicing of a consonant is modified by the voicing of the following consonant. French subjects pronounced sentences containing words ...

Data assimilation is the process of integrating observational data and model predictions to obtain an optimal representation of the state of the atmosphere. As more chemical observations in the troposphere are becoming available, chemical data assimilation is expected to play an essential role in air quality forecasting, similar to the role it has in numerical weather prediction. Considerable p...

In this paper we investigate patterns of place and stricture assimilation of Argentine Spanish nasals in order to test two competing models of phonological representations of place and stricture features (or tract variables). Electropalatographic (EPG) data from four speakers of Buenos Aires Spanish reveal that nasal assimilation before coronals within words (e.g. in /kanta/, /kansa/, /anʧa/) i...

I develop a model to explain many empirical facts about cultural assimilation and cultural change, and to make new empirically-relevant predictions about the efficiency of assimilation trajectories and the investments people make before and after migration. The model conceptualizes cultural assimilation as the accumulation of culture-specific capital and a choice between different production fu...

Operational wave data assimilation at ECMWF started with ERS-1 radar altimeter wave heights on 15 August 1993. This had a significant impact on the wave model analysis and forecast. The impact of wave data assimilation based on the ECMWF experience is presented. This includes the impact of assimilation of ERS radar altimeter and synthetic aperture radar and ENVISAT radar altimeter-2 wave data. ...

Data assimilation obtains improved estimates of the state of a physical system by combining imperfect model results with sparse and noisy observations of reality. Not all observations used in data assimilation are equally valuable. The ability to characterize the usefulness of different data points is important for analyzing the effectiveness of the assimilation system, for data pruning, and fo...

A Global Carbon Assimilation System based on the ensemble Kalman filter (GCAS-EK) is developed for assimilating atmospheric CO2 data into an ecosystem model to simultaneously estimate the surface carbon fluxes and atmospheric CO2 distribution. This assimilation approach is similar to CarbonTracker, but with several new developments, including inclusion of atmospheric CO2 concentration in state ...

Literature is divided on whether enterprise systems promote or hinder organizational agility. To the best of our knowledge, this paradox has never been rigorously theoretically analyzed nor empirically investigated. This paper seeks to address this paradox by leveraging upon innovation assimilation literature and knowledge based and capabilities based views of organizations. We propose a theore...

The impact of dark NH4+ and N03assimilation on photosynthetic light harvesting capability of the green alga Selenastrum minutum was monitored by chlorophyll a fluorescence analysis. When cells assimilated NH4+, they exhibited a large decline in the variable fluorescence/maximum fluorescence ratio, the fluorescence yield of photosystem 11 relative to that of photosystem I at 77 kelvin, and 02 ev...
