Tropospheric ozone is a dangerous atmospheric pollutant for forest ecosystems when it penetrates stomata. Thresholds ozone-risk assessment are based on accumulated stomatal fluxes such as the Phytotoxic Ozone Dose (POD). In order to identify effect of Holm oak in central Italy, four flux-based impact response functions were implemented and tested multi-layer canopy model AIRTREE evaluated again...

Suitable groundwater level is an important foundation for the stability of ecological environment, and healthy development social economy, in arid area Northwest China. The Manas River Basin a typical oasis area, where problems salinization desertification are prominent. By analyzing variation characteristics study from 2013 to 2019 combined with remote sensing technology—according theory capil...

The transmit power and the carrier sense threshold are two major MAC/PHY parameters in CSMA/CA wireless networks. The problem of transmit power control has been extensively studied in the context of graph-theoretic topology control and maintenance. What has not been studied in depth is the effect of signal to interference plus noise ratio (SINR) on the topology and the network capacity sustaine...

In this paper, a dynamic version of the Guard Channel Scheme (GCS) for cellular networks is illustrated to show the relation between bandwidth threshold and system mobility. The bandwidth threshold is dynamically changed according to mobility values. We propose a new equation which shows the relation between bandwidth threshold (Bt) and mobility. The effect of mobility on Bt is investigated usi...

A dynamic mass definition near the t ¯ t threshold

The threshold voltage for action potential generation is a key regulator of neuronal signal processing, yet the mechanism of its dynamic variation is still not well described. In this paper, we propose that threshold phenomena can be classified as parameter thresholds and state thresholds. Voltage thresholds which belong to the state threshold are determined by the 'general separatrix' in state...
