Towards the improvement of the understanding of force/stress distribution in granular media under load, a new experimental approach is suggested. Neutron diffraction, a non-conventional experimental technique, has been successfully used to map the evolution of intragranular strains in sand specimens loaded in a novel plane-strain apparatus. Representative preliminary results from recent experiment
In this review, we present an up-to-date phenomenological summary of research developments in the physics of the Quark-Gluon Plasma (QGP). A short historical perspective and theoretical motivation for this rapidly developing field of contemporary particle physics is provided. In addition, we introduce and discuss the role of the quantum chromodynamics (QCD) ground state, non-perturbative and latti
Since 2009, the Ministry of Public Health (MoPH) in Lebanon has been going through a major reform initiative to improve its contracting system with private and public hospitals. The private sector is the main provider of hospital care in the country and the main contractor to the MoPH for the provision of curative care. As an “insurer of last resort,” the MoPH plays an important role in providing
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
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
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.
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.
