Recently, it was proposed to use negatively charged electron beams for compensation of beam-beam effects due to protons in the Tevatron collider [1]. We show that a similar compensation is possible in space-charge dominated low energy proton beams. The idea has a potential of several-fold increase of the FNAL Booster beam brightness. Best results will be obtained using three electron lenses aro...

evidence occupies a paramount position in any logical endeavor and research article is consensually considered a predominant site of such an endeavor. one interesting area of rhetoric which addresses the source and reliability of evidence is quality metadiscourse. in this qualitative study, quality metadiscourse strategies (i.e., evidentials, hedges, boosters and disclaimers) are examined to in...

In 1987, Kalai proved that stacked spheres of dimension d ≥ 3 are characterised by the fact that they attain equality in Barnette’s celebrated Lower Bound Theorem. This result does not extend to dimension d = 2. In this article, we give a characterisation of stacked 2-spheres using what we call the separation index. Namely, we show that the separation index of a triangulated 2-sphere is maximal...

Abstract Background A balanced diet and nutrition greatly influence our immune system’s ability regulate the risk severity of infections. This review presented possible patho-mechanisms vitamins C D in COVID-19 immunity. Main body Deregulation system including decreased level boosters is invariably reported COVID-19. Vitamin vitamin are among boosters; homeostasis those was found essential for ...
