Phylogenetic clustering of fungal communities in human‐disturbed streams

open access: yesEcosphere, 2016
Phylogenetic community structure is increasingly used to examine community assembly, but the influence of anthropogenic disturbance on phylogenetic community structure remains little explored.

To be Neutral or Not Neutral? The In-Network Caching Dilemma

open access: yesIEEE Internet Computing, 2018
Caching allows Internet Service Providers (ISPs) to reduce network traffic and Content Providers (CPs) to increase the offered QoS. However, when contents are encrypted, effective caching is possible only if ISPs and CPs cooperate. We suggest possible forms of non-discriminatory cooperation that make caching compliant with the principles of Net ...

Hungarian neutral vowels [PDF]

open access: yes, 2013
In Hungarian, stems containing only front unrounded (neutral) vowels fall into two groups: one group taking front suffixes, the other taking back suffixes in vowel harmony. The distinction is traditionally thought of as purely lexical.

Oscillation of a higher order neutral difference equation with a forcing term

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1999
The authors obtain oscillation results for the even order forced neutral difference equation Δm(yn+pnyn−k)+qnf(yn−ℓ)=hn.                                (*) Examples illustrating the results are included.

Neutrality in the Metaorganism

open access: yesPLOS Biology, 2018
Abstract Almost all animals and plants are inhabited by diverse communities of microorganisms, the microbiota, thereby forming an integrated entity, the metaorganism. Natural selection should favor hosts that shape the community composition of these microbes to promote a beneficial host-microbe symbiosis. Indeed, animal hosts often pose

Nonoscillation and Oscillation Criteria for a Class of Second-Order Nonlinear Neutral Delay Differential Equations with Positive and Negative Coefficients

open access: yesAxioms, 2022
In this paper, we investigate some nonoscillatory and oscillatory solutions for a class of second-order nonlinear neutral delay differential equations with positive and negative coefficients.

Periodic solutions of a neutral impulsive differential equation

open access: yes上海师范大学学报. 自然科学版, 2017
In this paper, we consider a neutral impulsive differential equation. An impulsive predatorprey model with non-monotonic functional response is investigated. Some novel sufficient conditions are obtained for the nonexistence of periodic solutions and the

A niche for neutrality [PDF]

open access: yesEcology Letters, 2007
Abstract Ecologists now recognize that controversy over the relative importance of niches and neutrality cannot be resolved by analyzing species abundance patterns. Here, we use classical coexistence theory to reframe the debate in terms of stabilizing mechanisms (niches) and fitness equivalence (neutrality).

The edge of neutral evolution in social dilemmas [PDF]

open access: yes, 2009
The functioning of animal as well as human societies fundamentally relies on cooperation. Yet, defection is often favorable for the selfish individual, and social dilemmas arise.

Sustainable evaluation and optimization strategies for black tea production: insights from emergy analysis

open access: yesCogent Food & Agriculture
The extensive scale of tea production has resulted in a substantial demand for inputs such as fertilizers and pesticides in tea gardens, contributing to increased greenhouse gas emissions and environmental challenges.
