Transition probabilities for general birth-death processes with applications in ecology, genetics, and evolution [PDF]

J Math Biol, 65:553-580, 2012, 2011
A birth-death process is a continuous-time Markov chain that counts the number of particles in a system over time. In the general process with $n$ current particles, a new particle is born with instantaneous rate $\lambda_n$ and a particle dies with instantaneous rate $\mu_n$.

Marine Gel Interactions with Hydrophilic and Hydrophobic Pollutants

Gels, 2021
Microgels play critical roles in a variety of processes in the ocean, including element cycling, particle interactions, microbial ecology, food web dynamics, air–sea exchange, and pollutant distribution and transport.

Study on Characteristic Spectrum and Multiple Classifier Fusion With Different Particle Size in Marine Sediments

IEEE Access, 2020
Marine sediments record much information of the ecological process, which highly correlated with global and local environmental change. Particle size and its distributions of sediments indicate different ecological functions, thus are the key questions ...

Bayesian deep learning for error estimation in the analysis of anomalous diffusion

Nature Communications, 2022
Modern single-particle-tracking techniques produce extensive time-series of diffusive motion in a wide variety of systems, from single-molecule motion in living-cells to movement ecology.

Effects of Ecological Restoration on the Distribution of Soil Particles and Organic Carbon in Alpine Regions

Separations, 2022
This study discusses the impact of two different ecological restoration approaches on the distribution of soil particle size and organic carbon, expecting to provide references for research on the effects of ecological restoration on the soil carbon pool in alpine regions.

Isotopic constraints on the atmospheric sources and formation of nitrogenous species in clouds influenced by biomass burning [PDF]

Atmospheric Chemistry and Physics, 2019
Predicting tropospheric cloud formation and subsequent nutrient deposition relies on understanding the sources and processes affecting aerosol constituents of the atmosphere that are preserved in cloud water.

Evolutionary Fields Can Explain Patterns of High Dimensional Complexity in Ecology [PDF]

Phys. Rev. E 95, 042401 (2017), 2016
One of the properties that make ecological systems so unique is the range of complex behavioural patterns that can be exhibited by even the simplest communities with only a few species. Much of this complexity is commonly attributed to stochastic factors which have very high-degrees of freedom.

Anthropic arguments outside of cosmology and string theory [PDF]

Belgrade Philosophical Annual, 2016
Anthropic reasoning has lately been strongly associated with the string theory landscape and some theories of particle cosmology, such as cosmological inflation. The association is not, contrary to multiple statements by physicists and philosophers alike,
