Degradation of plant patches is considered as one of the indices for rangeland degrading health condition. Investigating the accuracy of triple indices (infiltration, stability and soil nutrient cycle) presented by LFA method seems necessary to determine its efficiency in semi-arid areas with the least cost. This study aims to investigate the role of vegetative species and growing forms on soil...

Background: Recently, it has been shown that increasing body mass index (BMI) in asthma is associated with reduced exhaled NO. Our objective in this study was to determine if the BMIrelated changes in exhaled NO differ across asthmatics and controls, and to determine if these changes are related to increased airway oxidative stress and systemic levels of leptin and adiponectin. Methods: Observa...

Variability in speaking rate results in a many-to-many mapping between acoustic properties in speech and the linguistic interpretation of an utterance. In order to recognize the phonetic structure of an utterance, listeners must calibrate their phonetic decisions against the rate at which the speech was produced. This process of rate normalization is fast and effective allowing listeners to mai...

interrupting the processes which control ecosystem resources has dramatic impacts on the rangeland conditions. to protect ecosystems and landscape, it needs to understand the ecosystem processes which regulate the ecosystem resources. as main components of ecosystems, patches and inter-patches play important roles in energy and materials cascade. ecologically, functional parameters such as stab...

In this issue of Neuron, Nandy et al. (2017) reveal a number of important new insights into the neural mechanisms that are responsible for attentional selection.
