TL;DR: In this paper, the authors demonstrate that a single squall line propagating across Amazonia in January, 2005, caused widespread forest tree mortality and may have contributed to the elevated mortality observed that year.
Abstract: [1] Climate change is expected to increase the intensity of extreme precipitation events in Amazonia that in turn might produce more forest blowdowns associated with convective storms. Yet quantitative tree mortality associated with convective storms has never been reported across Amazonia, representing an important additional source of carbon to the atmosphere. Here we demonstrate that a single squall line (aligned cluster of convective storm cells) propagating across Amazonia in January, 2005, caused widespread forest tree mortality and may have contributed to the elevated mortality observed that year. Forest plot data demonstrated that the same year represented the second highest mortality rate over a 15-year annual monitoring interval. Over the Manaus region, disturbed forest patches generated by the squall followed a power-law distribution (scaling exponent α = 1.48) and produced a mortality of 0.3–0.5 million trees, equivalent to 30% of the observed annual deforestation reported in 2005 over the same area. Basin-wide, potential tree mortality from this one event was estimated at 542 ± 121 million trees, equivalent to 23% of the mean annual biomass accumulation estimated for these forests. Our results highlight the vulnerability of Amazon trees to wind-driven mortality associated with convective storms. Storm intensity is expected to increase with a warming climate, which would result in additional tree mortality and carbon release to the atmosphere, with the potential to further warm the climate system.

TL;DR: This paper extends the study of the X chart with variable parameters to include variable action limits, and presents a meta-analyses of the response of the immune system to these limits.
Abstract: Varying the parameters of the X chart has been explored extensively in recent years. In this paper, we extend the study of the X chart with variable parameters to include variable action limits. ...

TL;DR: It is shown that when all four external states are Neveu-Schwarz states, the two-loop amplitude coincides with the Ramond-Neveu -SchwarZ result.
Abstract: The pure spinor formalism for the superstring has recently been used to compute massless four-point two-loop amplitudes in a manifestly super-Poincare covariant manner. In this Letter, we show that when all four external states are Neveu-Schwarz states, the two-loop amplitude coincides with the Ramond-Neveu-Schwarz result.

TL;DR: These guidelines are an up-to-date and comprehensive tool to aid health professionals in treating smokers, recommending measures and strategies for managing each case based on clinical evidence.
Abstract: These guidelines are an up-to-date and comprehensive tool to aid health professionals in treating smokers, recommending measures and strategies for managing each case based on clinical evidence. Written in a simplified and objective manner, the text is divided into two principal sections: Evaluation and Treatment. The sections both present comments on and levels of evidence represented by the references cited, as well as some proposals for the reduction of damage and for intervening in specific and still poorly explored situations, such as relapse, passive smoking, physician smoking, and tobacco use in specific environments.
