No pause in the increase of hot temperature extremes
Observational data show a continued increase of hot extremes over land during the so-called global warming hiatus. This tendency is greater for the most extreme events and thus more relevant for impacts than changes in global mean temperature.

Dust Temperatures Around Hot Stars [PDF]
Infrared and spectroscopic observations of hot stars in clusters, groups, and the field are interpreted. Their circumstellar dust shells are found to have greater inner radii for the hotter stars, so that the stellar and dust temperatures are anti-correlated. There is also evidence that the hotter forbidden-line stars have thicker dust shells. The time

A search for the Mpemba effect: When hot water freezes faster then cold water [PDF]
An explanation for why hot water will sometime freeze more rapidly than cold water is offered. Two specimens of water from the same source will often have different spontaneous freezing temperatures; that is, the temperature at which freezing begins. When both specimens supercool and the spontaneous freezing temperature of the hot water is higher than ...

Thermoelectric Properties of Nanocomposite Heavy Fermion CeCu6 [PDF]
Samples of heavy fermion compound CeCu6 were prepared by hot-press technique. Temperature-dependent (5-300 K) thermoelectric transport properties of the samples were measured. The dimensionless figure-of-merit (ZT) was optimized by varying the hot-pressing temperature.

The Atmospheric Circulation of Ultra-hot Jupiters [PDF]
Recent observations of ultra-hot Jupiters with dayside temperatures in excess of $2500~\mathrm{K}$ have found evidence for new physical processes at play in their atmospheres. In this work, we investigate the effects of the dissociation of molecular hydrogen and recombination of atomic hydrogen on the atmospheric circulation of ultra-hot Jupiters.

Ultrafast Studies of Hot-Hole Dynamics in Au/p-GaN Heterostructures [PDF]
Harvesting non-equilibrium hot carriers from photo-excited metal nanoparticles has enabled plasmon-driven photochemical transformations and tunable photodetection with resonant nanoantennas. Despite numerous studies on the ultrafast dynamics of hot electrons, to date, the temporal evolution of hot holes in metal-semiconductor heterostructures remains ...

Dissimilar Ferromagnetic Layer Dependence of Hot Electron Magnetotransport [PDF]
The material dependence of hot electron magnetotransport in a spin-valve transistor has been theoretically explored. We calculate the parallel and anti-parallel collector current changing the types and relative spin orientation of the ferromagnetic layers. The magnetocurrent has been presented as well.

CS Lines Profiles in Hot Cores
We present a theoretical study of CS line profiles in archetypal hot cores. We provide estimates of line fluxes from the CS(1-0) to the CS(15-14) transitions and present the temporal variation of these fluxes.
