On the Bivariate Nakagami‐Lognormal Distribution and Its Correlation Properties
International Journal of Antennas and Propagation, Volume 2014, Issue 1, 2014., 2014 The bivariate Nakagami‐lognormal distribution used to model the composite fast fading and shadowing has been examined exhaustively. In particular, we have derived the joint probability density function, the cross‐moments, and the correlation coefficient in power terms.

Fading Evaluation in the 60 GHz Band in Line‐of‐Sight Conditions
International Journal of Antennas and Propagation, Volume 2014, Issue 1, 2014., 2014 An exhaustive analysis of the small‐scale fading amplitude in the 60 GHz band is addressed for line‐of‐sight conditions (LOS). From a measurement campaign carried out in a laboratory, we have estimated the distribution of the small‐scale fading amplitude over a bandwidth of 9 GHz. From the measured data, we have estimated the parameters of the Rayleigh,

Spatiotemporal Dynamics of Non‐Ecological Speciation in Rubyspot Damselflies (Hetaerina spp.)
Molecular Ecology, Volume 34, Issue 12, June 2025.ABSTRACT Non‐ecological speciation is a common mode of speciation, which occurs when allopatric lineages diverge in the absence of pronounced ecological differences. Yet, relative to other speciation mechanisms, non‐ecological speciation remains understudied.

Gamma radiation-induced impairment of hippocampal neurogenesis, comparison of single and fractionated dose regimens Deterioro de la neurogénesis en el hipocampo inducida por radiación gamma, comparación de los regímenes de dosis única y fraccionada [PDF]
, 2012 Radiation therapy of the brain is associated with many consequences, including cognitive disorders. Pathogenesis of radiation induced cognitive disorder is not clear, but reduction of neurogenesis in hippocampus may be an underlying reason. 24 adult male

Journal of Ecology, Volume 112, Issue 3, Page 446-460, March 2024.Our study highlights the relevance of evolution from common ancestors and shared history underpinning large seagrass phylogenetic structuring. Abstract Phylogenetic signal (PS) is the propensity of closely related species to resemble each other. PS has been tested across clades of terrestrial plants; however, insight for seagrasses is still lacking ...

Radionuclides in arctic marine macroalgae from Kongsfjorden (Svalbard) [PDF]
, 2018 Seaweeds are known to be useful environmental bioindicators since they bioaccumulate radioisotopes at very low environmental concentrations. Levels of natural radionuclides in six ecologically relevant brown and red seaweed species from Arctic coasts ...
