Sensitivity of age of air trends to the derivation method for non-linear increasing inert SF6 [PDF]

open access: yesAtmospheric Chemistry and Physics, 2020
Mean age of air (AoA) is a diagnostic of transport along the stratospheric Brewer–Dobson circulation. While models consistently show negative trends, long-term time series (1975–2016) of AoA derived from observations show non-significant positive trends ...

Evaluation of several initialization methods on arithmetic optimization algorithm performance

open access: yesJournal of Intelligent Systems, 2021
Arithmetic optimization algorithm (AOA) is one of the recently proposed population-based metaheuristic algorithms. The algorithmic design concept of the AOA is based on the distributive behavior of arithmetic operators, namely, multiplication (M ...

Beyond Valence and Arousal: The Role of Age of Acquisition in Emotion Word Recognition

open access: yesBehavioral Sciences, 2023
Although the age of acquisition (AoA) effect has been established in numerous studies, how emotion word processing is modulated by AoA, along with affective factors, such as valence and arousal, is not well understood.

The ecological dichotomy of ammonia-oxidizing archaea and bacteria in the hyper-arid soils of the Antarctic Dry Valleys [PDF]

open access: yes, 2014
The McMurdo Dry Valleys of Antarctica are considered to be one of the most physically and chemically extreme terrestrial environments on the Earth. However, little is known about the organisms involved in nitrogen transformations in these environments ...

Word frequency affects naming latency in Dutch when age of acquisition is controlled. [PDF]

open access: yes, 1996
Morrison and Ellis (1995) claim that most evidence of frequency effects in word recognition is not genuine but an artefact of the age at which the words have been acquired.

Three-dimensional positioning algorithm based on TDOA and AOA in coal mine underground

open access: yesGong-kuang zidonghua, 2015
In view of problem that positioning accuracy of existing underground positioning algorithm is difficult to meet actual demand, a three-dimensional positioning algorithm based on TDOA and AOA used in coal mine underground was proposed combining with ...

Optimal Precoders for Tracking the AoD and AoA of a mm-Wave Path [PDF]

open access: yes, 2018
In millimeter-wave channels, most of the received energy is carried by a few paths. Traditional precoders sweep the angle-of-departure (AoD) and angle-of-arrival (AoA) space with directional precoders to identify directions with largest power.

Niche differentiation of ammonia-oxidizing archaea and related autotrophic carbon fixation potential in the water column of the South China Sea

open access: yesiScience, 2022
Summary: The significant primary production by ammonia-oxidizing archaea (AOA) in the ocean was reported, but the carbon fixation process of AOA and its community composition along the water depth remain unclear.

Dissociating word frequency and age of acquisition: The Klein effect revived (and reversed). [PDF]

open access: yes, 2006
The Klein effect (G. S. Klein, 1964) refers to the finding that high-frequency words produce greater interference in a color-naming task than low-frequency words.
