Hadron Properties with FLIC Fermions
The Fat-Link Irrelevant Clover (FLIC) fermion action provides a new form of
nonperturbative O(a)-improvement in lattice fermion actions offering near
continuum results at finite lattice spacing. It provides computationally
inexpensive access to the light quark mass regime of QCD where chiral
nonanalytic behaviour associated with Goldstone bosons is revealed. The
motivation and formulation of FLIC fermions, its excellent scaling properties
and its low-lying hadron mass phenomenology are presented.Comment: 29 pages, 13 figures, 6 tables. Contribution to lecure notes in 2nd

NouveautĂ©s dans la prise en charge de lâasthme [Novelties in the Treatment of Asthma]
For general practitioners there have been important novelties in the treatment of asthma due to recent modifications of the international guidelines from Global Initiative for Asthma (GINA). In Step 1, use of short-acting beta2-agonists (SABA) without concomitant inhaled corticosteroids (ICS) as controller is no longer recommended for lack of efficacy and safety reasons. Instead, low dose ICS-formoterol as needed is recommended. In Step 5, in patients with severe uncontrolled asthma GINA recommends targeted biologic therapies like interleukin antibodies. Asthma patients presenting simultaneously with symptoms of chronic obstructive pulmonary disease (COPD) should receive treatment containing ICS. Independent of the current corona pandemic, GINA recommendations stay in place
