Adaptive, convergent origins of the pygmy phenotype in African rainforest hunter-gatherers

The evolutionary history of the human pygmy phenotype (small body size), a characteristic of African and Southeast Asian rainforest hunter-gatherers, is largely unknown. Here we use a genome-wide admixture mapping analysis to identify 16 genomic regions th ...

Crosslingual Tandem-SGMM: Exploiting Out-Of-Language Data for Acoustic Model and Feature Level Adaptation

Petr Motlicek, Philip Neil Garner, David Imseng

Recent studies have shown that speech recognizers may benefit from data in languages other than the target language through efficient acoustic model- or feature-level adaptation. Crosslingual Tandem-Subspace Gaussian Mixture Models (SGMM) are successfully ...

Sorting genomes with rearrangements and segmental duplications through trajectory graphs

Bernard Moret, Yu Lin, Mingfu Shao

We study the problem of sorting genomes under an evolutionary model that includes genomic rearrangements and segmental duplications. We propose an iterative algorithm to improve any initial evolutionary trajectory between two genomes in terms of parsimony. ...

Competing islands limit the rate of adaptation in structured populations

Cornelia Pokalyuk

Beneficial mutations can co-occur when population structure slows down adaptation. Here, we consider the process of adaptation in asexual populations distributed over several locations ("islands"). New beneficial mutations arise at constant rate u(b), and ...

Adaptation and learning over complex networks [From the Guest Editors]

Ali H. Sayed

The topic of this special issue deals with a subject matter that has been receiving immense attention from various research communities, and not only within the signal processing community. Discusses research and development in the area of the adaption and ...

A multiscale landscape genomics analytical framework to identify local adaptive variation in the Buckler Mustard

Stéphane Joost, Kevin Leempoel

The question of finding an appropriate scale to study adaptation emerged only recently in landscape genomics, while in landscape ecology its components (extent and resolution or grain) have been addressed in many papers. In fact, in landscape genetics only ...

Personalized Drug Administrations Using Support Vector Machine

Giovanni De Micheli, Alena Simalatsar, Wenqi You Dubout

The decision-making process regarding drug dose, regularly used in everyday medical practice, is critical to patients’ health and recovery. It is a challenging process, especially for a drug with narrow therapeutic ranges, in which a medical doctor decides ...

Temporal whitening by power-law adaptation in neocortical neurons

Wulfram Gerstner, Richard Naud, Skander Mensi, Christian Antonio Pozzorini

Spike-frequency adaptation (SFA) is widespread in the CNS, but its function remains unclear. In neocortical pyramidal neurons, adaptation manifests itself by an increase in the firing threshold and by adaptation currents triggered after each spike. Combini ...

An ancestral regulatory mechanism underlies Hoxd gene expression in both developing genitals and digits

Nicolas Lonfat

Coordinated expression of HoxD cluster genes is crucial for the emergence and patterning of both developing digits and external genitalia. As a shared evolutionary origin has been proposed for these secondary structures, which may have accompanied the tran ...
