To date, the proposed observation of Young Stellar Objects (YSOs) in Galactic center (GC) still raises question where and how these objects could have formed due to violent vicinity Sgr~A*. Here, we report multi-wavelength detection a highly dynamic YSO close Sgr~A* that might be member IRS13 cluster. We observe beforehand known coreless bow-shock source X3 near- mid-infrared (NIR/MIR) with SIN...

Abstract MWC 349A is a massive star with well-known circumstellar disk rotating following Keplerian law, and an ionized wind launched from the surface. Recent observations Atacama Large Millimeter/submillimeter Array (ALMA) carried out toward this system, however, have revealed additional high-velocity component in strong, maser emission of hydrogen radio recombination lines (RRLs), suggesting ...

This paper presents a political economy model of inflation as a result of social conflict. Agents are heterogeneous in terms of income. Agents’ income levels determine their ability to hedge against the effects of inflation. The interaction of heterogeneous cash holdings and preferences over fiscal policy leads to conflict over how to finance government expenditure. The model makes a number of ...

Fitness cost associated with resistance to fluoroquinolones was recently shown to vary across clones of methicillin-resistant Staphylococcus aureus and extended-spectrum β-lactamase-producing Klebsiella pneumoniae. The resulting dissimilar fitness should have influenced the clonal dynamics and thereby the rates of resistance for these pathogens. Moreover, a similar mechanism was recently propos...
