Operational quantum theory without predefined time

The standard formulation of quantum theory assumes a predefined notion of time.This is a major obstacle in the search for a quantum theory of gravity, where the causal structure of space-time is expected to be dynamical and fundamentally probabilistic in character.Here, we propose a generalized formulation of quantum theory without predefined time

Response of bacterial communities to variation in water quality and physicochemical conditions in a river-reservoir system

The construction of high dams results in changes to the ecohydrology processes of river reaches both upstream and downstream of the dam, in addition to causing stratification of reservoir waters.Changes in these hydrodynamic processes then lead to changes in the habitats and nutrients of the waters that are important for basal food chain organisms,
