This work deals with the estimation of the extreme value index and extreme quantiles for heavy tailed data, randomly right truncated by another heavy tailed variable. Under mild assumptions and the condition that the truncated variable is less heavy-tailed than the truncating variable, asymptotic normality is proved for both estimators. The proposed estimator of the extreme value index is an ad...

Global warming and the associated rise in extreme temperatures substantially increase the chance of concurrent droughts and heat waves. The 2014 California drought is an archetype of an event characterized by not only low precipitation but also extreme high temperatures. From the raging wildfires, to record low storage levels and snowpack conditions, the impacts of this event can be felt throug...

The global hydrological cycle is predicted to be intensified under the warming climate, with more extreme precipitation events and longer dry spell in between. Here, we evaluated how (EPEs) antecedent (dry-EPEs) wet (wet-EPEs) water conditions influence carbon exchange along gradient of arid, semi-arid, sub-humid ecosystems based on eddy covariance datasets. After EPEs, ecosystem respiration gr...

We investigate the high and low energy scattering of charged scalar waves from an extreme dilaton black hole (DBH). The analyses here correspond to forward scattering processes of two charged scalar particles with dilaton coupling under a certain extreme condition. We calculate the scattering amplitude and compare it with the known results obtained by other methods. We also discuss the case of ...

Pseudohyperkalemia occurs occasionally in patients with extreme leukocytosis. Increased white blood cell fragility coupled with mechanical stress is felt to be causal. Serum and plasma potassium levels have been both associated with pseudohyperkalemia. Whole blood potassium determination will usually verify the correct diagnosis. It is important to diagnose this condition early so that patients...
