An Eco-Evolutionary approach of Adaptation and Recombination in a large population of varying size [PDF]

, 2014
We identify the genetic signature of a selective sweep in a population described by a birth-and-death process with density dependent competition. We study the limit behaviour for large K, where K scales the population size.

Four-Objective Optimization of Irreversible Atkinson Cycle Based on NSGA-II

Entropy, 2020
Variation trends of dimensionless power density (PD) with a compression ratio and thermal efficiency (TE) are discussed according to the irreversible Atkinson cycle (AC) model established in previous literature.

Multi-Objective Optimization of an Irreversible Single Resonance Energy-Selective Electron Heat Engine

Energies, 2022
Based on the model of irreversible single resonance energy-selective electron heat engine established in the previous literature, this paper applies finite-time thermodynamic theory and NSGA-II algorithm to perform multi-objective optimization.

Effect of Land-use Management Systems on Coupled Hydraulic Mechanical Soil Processes Defining the Climate-Food-Energy-Water Nexus. [PDF]

Bulgarian Journal of Soil Science, 2019
Soils are the most critical life-supporting compartments of the biosphere. They provide numerous ecosystem services such as habitat for biodiversity, water and nutrients, as well as producing food, feed, fiber and energy.

Four-Objective Optimizations for an Improved Irreversible Closed Modified Simple Brayton Cycle

Entropy, 2021
An improved irreversible closed modified simple Brayton cycle model with one isothermal heating process is established in this paper by using finite time thermodynamics. The heat reservoirs are variable-temperature ones.

Intergenerational justice of what: welfare, resources or capabilities? [PDF]

, 2007
An important aspect of intergenerational justice concerns the specification of a 'currency of advantage' that can be used to evaluate distributive outcomes across time.

Spatial Scaling in Model Plant Communities

, 2005
We present an analytically tractable variant of the voter model that provides a quantitatively accurate description of beta-diversity (two-point correlation function) in two tropical forests.

Considering Intra-individual Genetic Heterogeneity to Understand Biodiversity [PDF]

, 2019
In this chapter, I am concerned with the concept of Intra-individual Genetic Hetereogeneity (IGH) and its potential influence on biodiversity estimates. Definitions of biological individuality are often indirectly dependent on genetic sampling -and vice ...

Functional foods: an ecologic perspective [PDF]

The American Journal of Clinical Nutrition, 2000
A functional food is defined as any food or food ingredient that may provide a health benefit beyond that conferred by the nutrients the food contains. As nutrition scientists move into this arena, they must build on the wealth of information that already exists in plant biology.

Dominance of forest structural traits in shaping soil bacterial community assembly in Beijing’s urban forests

Frontiers in Soil Science
Urban forests constitute vital ecological interfaces between built environments and natural systems, yet the mechanisms driving soil microbial community assembly in these ecosystems remain poorly understood.
