Quantifying Cognitive Factors in Lexical Decline

Transactions of the Association for Computational Linguistics, 2021
We adopt an evolutionary view on language change in which cognitive factors (in addition to social ones) affect the fitness of words and their success in the linguistic ecosystem.

Enhanced impulsive action selection in middle-aged adults - insights from an oculomotor Simon task

Frontiers in Aging Neuroscience, 2016
Several studies have investigated the age-related impact in cognitive action control. However, to our knowledge, none has focused on the effect of moderate age on the strength of automatic activation according to the activation suppression model.

Learning Lexical Subspaces in a Distributional Vector Space

Transactions of the Association for Computational Linguistics, 2020
In this paper, we propose LexSub, a novel approach towards unifying lexical and distributional semantics. We inject knowledge about lexical-semantic relations into distributional word embeddings by defining subspaces of the distributional vector space in

How Mean is the Mean?

Frontiers in Psychology, 2013
In this paper we voice concerns about the uncritical manner in which the mean is often used as a summary statistic in psychological research. We identify a number of implicit assumptions underlying the use of the mean and argue that the fragility of ...

Integrative clustering of multi-level 'omic data based on non-negative matrix factorization algorithm. [PDF]

PLoS ONE, 2017
Integrative analyses of high-throughput 'omic data, such as DNA methylation, DNA copy number alteration, mRNA and protein expression levels, have created unprecedented opportunities to understand the molecular basis of human disease.

Strong Population Genetic Structure for the Endangered Micro-Trapdoor Spider Moggridgea rainbowi (Mygalomorphae, Migidae) in Unburnt Habitat after Catastrophic Bushfires

Diversity, 2023
Catastrophic wildfires impacted large areas of western Kangaroo Island (KI), South Australia in 2019–2020, burning habitat for many species, including large proportions of the distributional range of the KI micro-trapdoor spider Moggridgea rainbowi ...

The effect of aging on the dynamics of reactive and proactive cognitive control of response interference

Frontiers in Psychology, 2016
A prime-target interference task was used to investigate the effects of cognitive aging on reactive and proactive control in which frequency confounds and feature repetitions were eliminated from the cognitive control measures.

Chaotic Mixing Analyses by Distribution Matrices

Applied Rheology, 2000
Abstract Distributive fluid mixing in laminar flows is studied using the concept of concentration distribution mapping matrices, which is based on the original ideas of Spencer & Wiley [1], describing the evolution of the composition of two fluids of identical viscosity with no interfacial tension.

Analysing Randomized Distributed Algorithms [PDF]

, 2004
Randomization is of paramount importance in practical applications and randomized algorithms are used widely, for example in co-ordinating distributed computer networks, message routing and cache management. The appeal of randomized algorithms is their simplicity and elegance.

Mecoptera of Canada [PDF]

ZooKeys, 2019
The Mecoptera are represented in Canada by 25 extant species in four families, an increase of three species since the prior assessment in 1979. An additional 18 or more species and one family are expected to occur in Canada based on distributional ...
