TL;DR: In this article, an estimate of the Earth's average land surface temperature for the period 1753 to 2011 was presented. But the authors used a large sampling of stations rather than having prior studies.

TL;DR: In this article, a new mathematical framework is presented for producing maps and large-scale averages of temperature changes from weather station thermometer data for the purposes of climate analysis, which allows inclusion of short and discontinuous temperature records, so nearly all digitally archived temperature data can be used.

TL;DR: In this paper, the authors reported an estimate of the Earth's average land surface temperature for the period 1753 to 2011 and used a larger sampling of stations than had prior studies.

TL;DR: The authors have substantially increased the output power and extraction efficiency of a free-electron laser operating at 34.6 GHz by tapering the wiggler magnetic field by using a taper that brought the magnetic field at the end of the wiggle down to 45% of its initial value.

TL;DR: The status of the research on muon colliders is discussed and plans are outlined for future theoretical and experimental studies in this paper, where various components in such colliders, starting from the proton accelerator needed to generate pions from a heavy-$Z$ target, proceeding through the phase rotation and decay, muon cooling, acceleration, storage in a collider ring, and the collider detector.
