Soils are subject to varying degrees of direct or indirect human disturbance, constituting a
major global change driver. Factoring out natural from direct and indirect human influence is …

The usual formula for transition probabilities in nonrelativistic quantum mechanics is generalized
to yield conditional probabilities for selected sequences of events at several different …

Root-associated microbes can improve plant growth, and they offer the potential to increase
crop resilience to future drought. Although our understanding of the complex feedbacks …

The thermodynamics of critical points in multicomponent systems, more generally systems
with more than two independent variables (including binary fluid mixtures, the helium λ …

A spin-1 Ising model, which simulates the thermodynamic behavior of He 3-He 4 mixtures
along the λ line and near the critical mixing point, is introduced and solved in the mean-field …

A rapid protocol for the extraction of total nucleic acids from environmental samples is described.
The method facilitates concomitant assessment of microbial 16S rRNA diversity by PCR …

The paper is concerned with methods for the estimation of the coalescence time (time since
the most recent common ancestor) of a sample of intraspecies DNA sequences. The …

Plant diversity strongly influences ecosystem functions and services, such as soil carbon
storage. However, the mechanisms underlying the positive plant diversity effects on soil carbon …

The following results are proved for a system of Ising spins σ i = ±1 in zero magnetic field
coupled by a purely ferromagnetic interaction of the form −Σ i<j J ij σ i σ j with J ij ≥ 0, for …
