Groundwater age distributions are used to estimate the parameters of Fickian, and non-Fickian, effective models of solute transport. Based on the similarities between the transport and age equations, we develop a deconvolution based approach that describes transport between two monitoring wells. We show that the proposed method gives exact estimates of the travel time distribution between two w...

Whole-genome duplications (WGDs), thought to facilitate evolutionary innovations and adaptations, have been uncovered in many phylogenetic lineages. WGDs are frequently inferred from duplicate age distributions, where they manifest themselves as peaks against a small-scale duplication background. However, the interpretation of duplicate age distributions is complicated by the use of K(S), the n...

This overview focuses on autobiographical odor memory and how information evoked by the olfactory sense may differ from memories evoked by visual or verbal information. Three key topics are addressed: (a) age distributions of evoked memories; (b) phenomenological experience; and (c) semantic processing. Current evidence suggests that memories triggered by olfactory information are localized to ...

Phylostratigraphy, originally designed for gene age estimation by BLAST-based protein homology searches of sequenced genomes, has been widely used for studying patterns and inferring mechanisms of gene origination and evolution. We previously showed by computer simulation that phylostratigraphy underestimates gene age for a nonnegligible fraction of genes and that the underestimation is severer...

The age of ground water in any given sample is a distributed quantity representing distributed provenance (in space and time) of the water. Conventional analysis of tracers such as unstable isotopes or anthropogenic chemical species gives discrete or binary measures of the presence of water of a given age. Modeled ground water age distributions provide a continuous measure of contributions from...

Aging is always present, tailoring our interactions with others, and postulating a finite lifespan during which we are able to exercise them. We consider the prisoner's dilemma game on a square lattice and examine how quenched age distributions and different aging protocols influence the evolution of cooperation when taking the life experience and knowledge accumulation into account as time pas...

Furthermore, it made use of umbilical girth, which was difficult to measure in the donkeys. The equation of Eley and French (1993) for adult donkeys also consistently overestimated the liveweights of the Moroccan donkeys. Hard working donkeys, particularly in areas where the feed supply is irregular, are more likely to be in poor than in good body condition. Unfortunately Eley and French (1993)...

Purpose – This study intends to present some inluences developed during the economic crisis related to the education area in some European countries. The study wants to present a comparative analysis among these European countries. Design/Methodology/Approach – This study is based on the Eurostat data series and is designed due to the statistical data processing. Findings – The study revealed s...

A considerable body of research focuses on why voter turnout changed — specifically, why it declined — in the 1960s and 1970s. Most models of the change focus on factors such as a decline in civic involvement or a shift in the age distribution toward younger citizens who vote less frequently. While these approaches have taught us much about voter turnout, they are puzzling in that none actually...
