Appropriate timing of antibiotic initiation in patients with sepsis or septic shock: a systematic review and meta-analysis [PDF]
The Korean Journal of Internal MedicineEvidence supporting antibiotic administration within 3 hours in sepsis without shock is limited. Therefore, we conducted a systematic review and meta-analysis to determine whether the timing of antibiotic initiation influences mortality in patients with ...

Afterglow Polarizations in a Stratified Medium with Effect of the Equal Arrival Time Surface
The Astrophysical Journal, 2023 The environment of a γ -ray burst has an important influence on the evolution of jet dynamics and its afterglow. Here we investigate the afterglow polarizations in a stratified medium with the equal arrival time surface (EATS) effect.

Zones of Influence and Shock Motion in a Shock Boundary Layer Interaction [PDF]
49th AIAA Aerospace Sciences Meeting including the New Horizons Forum and Aerospace Exposition, 2011 This paper aims at describing the main features of a shock reflection on a turbulent boundary layer. The data used for this analysis are the results of large-eddy simulations of the interaction carried out with three different shock intensities: from incipient to fully separated cases. Computational results are validated vs experiments obtained for the
