Understanding the “new” disruptive behavior at live music events: Group normative (mis)alignment and collective self‐regulation

Analyses of Social Issues and Public Policy, Volume 26, Issue 1, April 2026.
Recent years have seen increased reports of disruptive behavior at live music events, leading many to question the capacity of audiences to regulate their behavior. This matters both for positive audience experience and for crowd safety. Whilst some previous studies have examined violence in music audiences, there is almost no research looking at the ...

The Upper Atmosphere of Uranus from Stellar Occultations. II. Revised Temperatures in the Upper Stratosphere and Lower Thermosphere

The Planetary Science Journal
Measurements made by Voyager 2 during its flyby of Uranus in 1986 found warm stratospheric and hot thermospheric temperatures that cannot be explained by solar energy alone.

Strong Tidal Dissipation at Uranus?

The Planetary Science Journal, 2023
Geophysical estimates of paleo heat fluxes on the Uranian moons Miranda and Ariel are in the range of 25–75 mW m ^−2 . For a canonical Uranus dissipation factor Q = 18,000, expected equilibrium tidal heating rates for these satellites are less than 6 mW ...

Semi-Analytical Search for Sun-Synchronous and Planet Synchronous Orbits around Jupiter, Saturn, Uranus and Neptune

Mathematics, 2022
With the development of aerospace science and technology, more and more probes are expected to be deployed around extraterrestrial planets. In this paper, some special orbits around Jupiter, Saturn, Uranus, and Neptune are discussed and analyzed.

Astrometry of the main satellites of Uranus: 18 years of observations

, 2015
We determine accurate positions of the main satellites of Uranus: Miranda, Ariel, Umbriel, Titania, and Oberon. Positions of Uranus, as derived from those of these satellites, are also determined. The observational period spans from 1992 to 2011.

Fast Ultra‐Selective 1H‐15N 1D NMR Spectroscopy Unlocks Atom‐Resolved Dynamics of Low‐Complexity Protein Regions

Angewandte Chemie, Volume 138, Issue 13, 23 March 2026.
NMR 15N spin‐relaxation rates are a primary source of information for deciphering protein conformational dynamics, but they require unreasonable experimental times when their 1H‐15N 2D spectra are highly congested. We propose an ultra‐selective method, SNIPER, that greatly accelerates data collection of individual residues. This allows characterization

Selection of a common communication link geometry for Saturn, Uranus and Titan [PDF]

, 1974
Mission analysis link parametrics, considering a Pioneer baseline, are developed through launch energies, flyby radii, and trip time calculations. Projected is also a 1979 Jupiter Uranus opportunity for a derivative Mariner to fly to Uranus by using the ...

Early Dynamical Evolution of the Solar System: Pinning Down the Initial Condition of the Nice Model [PDF]

, 2010
In the recent years, the "Nice" model of solar system formation has attained an unprecedented level of success in reproducing much of the observed orbital architecture of the solar system by evolving the planets to their current locations from a more ...

Asymmetry in Uranus' High Energy Proton Radiation Belt

Geophysical Research Letters
Uranus is one of the least explored planets in our solar system, it exhibits a unique magnetic field structure which was observed by NASA's Voyager 2 mission nearly 50 years ago.
