Minerva-Australis. I. Design, Commissioning, and First Photometric Results by Crossfield, Ian Jm

“…In this first paper, we describe the design, photometric instrumentation, software, and science goals of MINERVA-Australis, and note key differences from its Northern Hemisphere counterpart, the MINERVA array. We use recent transit observations of four planets, WASP-2b, WASP-44b, WASP-45b, and HD 189733b, to demonstrate the photometric capabilities of MINERVA-Australis.…”

A Search for Neutrino Emission from Fast Radio Bursts with Six Years of IceCube Data

“…We set the most stringent limit obtained to date on neutrino fluence from FRBs with an E -2 energy spectrum assumed, which is 0.0021 GeV cm-2 per burst for emission timescales up to ∼102 s from the northern hemisphere stacking search.…”

Optimizing influenza vaccine composition: A machine learning approach by Bandi, Hari, Bertsimas, Dimitris

“…Through numerical experiments, we show that our proposed vaccine compositions could potentially lower morbidity by 11–14% and mortality by 8–11% over vaccine compositions proposed by World Health Organization (WHO) for Northern Hemisphere, and lower morbidity by 8–10% and mortality by 6–9% over vaccine compositions proposed by U.S. …”

Traveling planetary-scale Rossby waves in the winter stratosphere: The role of tropospheric baroclinic instability by Domeisen, Daniela I. V., Plumb, R. Alan

“…While the generation of planetary-scale traveling waves through the interaction of synoptic-scale waves is observed in a control run, when the model is truncated to permit only waves with zonal wave number 1 or 2, the long waves are found to increase in strength, leading to a considerably more active stratosphere including Sudden Warmings comparable in strength to Northern Hemisphere winter. This finding suggests that the role of tropospheric synoptic eddies is two-fold: while generating a weak planetary-scale wave flux into the stratosphere, their main effect is to suppress baroclinic instability of planetary-scale waves by stabilizing the tropospheric mean state.…”

Where do all the subtypes go? Temporal dynamics of H8-H12 influenza A viruses in waterfowl. by Wille, M, Latorre-Margalef, N, Tolf, C, Halpin, R, Wentworth, D, Fouchier, RAM, Raghwani, J, Pybus, OG, Olsen, B, Waldenström, J

“…Influenza A virus (IAV) is ubiquitous in waterfowl. In the northern hemisphere IAV prevalence is highest during the autumn and coincides with a peak in viral subtype diversity. …”

Solar signal propagation: The role of gravity waves and stratospheric sudden warmings by Cnossen, I, Lu, H, Bell, C, Gray, L, Joshi, M

“…We use a troposphere-stratosphere model of intermediate complexity to study the atmospheric response to an idealized solar forcing in the subtropical upper stratosphere during Northern Hemisphere (NH) early winter. We investigate two conditions that could influence poleward and downward propagation of the response: (1) the representation of gravity wave effects and (2) the presence/absence of stratospheric sudden warmings (SSWs). …”

The Anisotropy of the Ultra-High Energy Cosmic Rays by Evans, W, Ferrer, F, Sarkar, S

“…In decaying dark matter models, the amplitude of the anisotropy is controlled by the size of the Galactic halo, while the phase is controlled by the shape. In the northern hemisphere, the amplitude is about 0.5 for cusped haloes, but falls to roughly 0.3 for isothermal haloes. …”

Symmetric instability in cross-equatorial western boundary currents by Goldsworth, F, Marshall, D, Johnson, H

“…The upper limb of the Atlantic Meridional Overturning Circulation draws waters with negative potential vorticity from the southern hemisphere into the northern hemisphere. The North Brazil Current is one of the cross-equatorial pathways in which this occurs: upon crossing the equator, fluid parcels must modify their potential vorticity to render them stable to symmetric instability and to merge smoothly with the ocean interior. …”
