The complexity of streamflow processes inhibits significant information about catchment performance and its sensitivity to climate change. Little is known the severity change within coastal area monsoon–subtropical zone climatic transition. This study advances a quasi-local scale analysis simplify daily dynamics their relationship with monthly hydro-climatic series (1981–2020) using six gauging...

We suggest and investigate a scheme for non-deterministic noiseless linear amplification of coherent states using successive photon addition, (â(†))(2), where â(†) is the photon creation operator. We compare it with a previous proposal using the photon addition-then-subtraction, ââ(†), where â is the photon annihilation operator, that works as an appropriate amplifier only for weak light fields...

Investigating the trend of changes in drought as one of the natural disasters is essential. For this purpose, in the present study, the trend of changes in standardized precipitation-evapotranspiration drought index (SPEI) for the synoptic stations of Kerman province was evaluated for the years 1990 to 2018. The change trend of the SPEI time series was evaluated using two both Mann-Kendall and ...

The Ganges, Brahmaputra and Meghna (GBM) river basins occupy about 1.75 x 10 km of the Himalayan region. More than half a billion people in Nepal, India, Bhutan and Bangladesh are directly or indirectly dependent on the water resources of the GBM rivers. These river basins are characterized by diversified climatic patterns. Analyses of trends and persistence in precipitation over these river ba...
