Prevalence and Pharmacologic Treatment of Breathlessness in Severe Chronic Obstructive Pulmonary Disease

BackgroundChronic obstructive pulmonary disease (COPD) is a leading cause of morbidity and mortality worldwide. Chronic breathlessness is a feared and distressing symptom with significant impact on daily life. Little is known of the prevalence of breathlessness at the end of life in severe COPD. International guidelines support the use of opioids to treat breathlessness, but it is unknown how comm

Monte Carlo Tools

Given the current landscape in experimental high-energy physics, these lectures are focused on applications of event generators for hadron colliders such as the Tevatron and LHC. Much of this would also be relevant for e+e−machines like LEP, ILC and CLIC, or e±p machines like HERA, but with some differences not discussed here. Heavy-ion physics is not addressed, since it involves rather different as

Temporal Variation of Ecosystem Scale Methane Emission From a Boreal Fen in Relation to Temperature, Water Table Position, and Carbon Dioxide Fluxes

We have analyzed decade-long methane flux data set from a boreal fen, Siikaneva, together with data on environmental parameters and carbon dioxide exchange. The methane flux showed seasonal cycle but no systematic diel cycle. The highest fluxes were observed in July–August with average value of 73 nmol m−2 s−1. Wintertime fluxes were small but positive, with January–March average of 6.7 nmol m−2 s

QCD radiation off heavy particles

An algorithm for an improved description of final-state QCD radiation is introduced. It is matched to the first-order matrix elements for gluon emission in a host of decays, for processes within the Standard Model and the Minimal Supersymmetric extension thereof.

Gamma gamma interactions from real to virtual photons

A ‘complete’ framework for γγ/γ*γ/γ*γ* interactions is presented. The emphasis is on providing a model for γγ physics at all photon virtualities, including the difficult transition region Q2∼m2ρ.
