Constraints on evolutionary properties of GHz Peaked Spectrum galaxies [PDF]
Astronomy & Astrophysics, 2006 We have used the available samples of Gigahertz Peaked Spectrum (GPS) galaxies to investigate their evolution properties in the framework of the ``youth'' scenario. Care was taken to properly allow for the different selection criteria used to define the samples.

Philosophies, 2017 An important question facing contemporary philosophy of science is whether the natural sciences in terms of their historical records exhibit distinguishing developmental patterns or structures. At least two philosophical stances are possible in answering

Whether and when to share: Spectrum sensing as an evolutionary game [PDF]
8th International Conference on Cognitive Radio Oriented Wireless Networks, 2013 Cooperative spectrum sensing is an efficient sensing scheme for cognitive radio networks (CRNs), in which secondary users (SUs) share sensing results with other SUs to improve the overall sensing performance. For a single SU, if the sensing results are shared early, there is more time for data transmission, which improves the throughput.

Factors shaping the abundance and diversity of the gut archaeome across the animal kingdom
Nature Communications, 2022 Here, by analyzing 250 species of animals covering a large taxonomic spectrum, the authors show that archaea are common constituent of the animal gut throughout the animal kingdom, and identify six main genera/families of gut archaea revealing their ...

Diversity and complexity in neural organoids
FEBS Letters, EarlyView.Neural organoid research aims to expand genetic diversity on one side and increase tissue complexity on the other. Chimeroids integrate multiple donor genomes within single organoids. Self‐organising multi‐identity organoids, exogenous cell seeding, or enforced assembly of region‐specific organoids contribute to tissue complexity.

Evolutionary Spectrum for Random Field and Missing Observations [PDF]
, 2012 There are innumerable situations where the data observed from a non-stationary random field are collected with missing values. In this work a consistent estimate of the evolutionary spectral density is given where some observations are randomly missing.

FEBS Letters, EarlyView.Proteostasis and the gut microbiota play a key role in shaping host physiology. Microbiota‐derived metabolites, vitamins, and RNA modulate host proteostasis. Findings from model systems, including C. elegans, indicate microbes can either stabilize or disrupt host proteostasis.

Evolutionary ecology of hares (Lepus spp.) from northwest Africa: the existence of cryptic species and description of a new species (Lepus saharae sp. nov.) [PDF]
, 2019 Objective: We examine the different pressures that lead to the occurrence of new species and thus to their phylogenies. From an evolutionary ecology perspective, we examine the phylogenetic relationships of different lineages, as well as the evolutionary
