Evolutionary Game Theory Perspective on Dynamic Spectrum Access Etiquette

open access: yesIEEE Access, 2018
In this paper, we describe the long-term evolution of societies of secondary users in dynamic spectrum access networks. Such an understanding is important to help us anticipate future trends in the organization of large-scale distributed networked ...

Tracer spectrum: a visualisation method for distributed evolutionary computation [PDF]

open access: yesGenetic Programming and Evolvable Machines, 2010
We present a novel visualisation method for island-based evolutionary algorithms based on the concept of tracers as adopted in medicine and molecular biology to follow a biochemical process. For example, a radioisotope or dye can be used to replace a stable component of a biological compound, and the signal from the radioisotope can be monitored as it ...

Hydration index and hydrated constitutive model of clay shale using acoustic frequency spectrum

open access: yesEnergy Science & Engineering, 2019
Clay shale is frequently encountered in drilling. With strong hydration capacity, when clay shale contacts with drilling fluid, rock structural and mechanical property will be affected, causing wellbore instability.

Evolutionary Philosophy of Science: A New Image of Science and Stance towards General Philosophy of Science

open access: yesPhilosophies, 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

Constraints on evolutionary properties of GHz Peaked Spectrum galaxies [PDF]

open access: yesAstronomy & 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.

STATISTICAL RESEARCH IN EVOLUTIONARY GENETIC RELATIONSHIP OF DMS-, DW-, KW- AND KE-TYPES OF DOUBLE STARS

open access: yesOdessa Astronomical Publications, 2017
Statistical relations as spectrum-period, mass of primary component-semi-major axes of an orbit, excesses of luminosity and radius-mass of component, Karetnikov's diagram, modern and initial distributions of the binaries in the 1 ps3 of Sun neighbourhood

Whether and when to share: Spectrum sensing as an evolutionary game [PDF]

open access: yes8th 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.

Spectrum Allocation of Cognitive Radio Based on Autonomy Evolutionary Algorithm

open access: yesCybernetics and Information Technologies, 2016
Reasonable and effective allocation of cognitive radio spectrum resource according to user’s requirements is the key task of cognitive radio network. Cognitive radio spectrum allocation problem can be viewed as an optimization problem.

Factors shaping the abundance and diversity of the gut archaeome across the animal kingdom

open access: yesNature 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 ...
