TL;DR: In this paper, a detailed theoretical model of the microwave cavity fields and the frequency shifts of the clock that they produce was presented, which significantly reduced the DCP uncertainty to 1.1? 10.16.
Abstract: We evaluate the distributed cavity phase (DCP) and microwave lensing frequency shifts, which were the two largest sources of uncertainty for the NPL-CsF2 caesium fountain clock. We report measurements that confirm a detailed theoretical model of the microwave cavity fields and the frequency shifts of the clock that they produce. The model and measurements significantly reduce the DCP uncertainty to 1.1 ? 10?16. We derive the microwave lensing frequency shift for a cylindrical cavity with circular apertures. An analytic result with reasonable approximations is given, in addition to a full calculation that indicates a shift of 6.2 ? 10?17. The measurements and theoretical models we report, along with improved evaluations of collisional and microwave leakage induced frequency shifts, reduce the frequency uncertainty of the NPL-CsF2 standard to 2.3 ? 10?16, nearly a factor of two lower than its most recent complete evaluation.

TL;DR: Quantitative electron, superresolution, and live-cell microscopy reveal that FCLs provide stable platforms for the recruitment of endocytic cargo in clathrin-coated pits.
Abstract: Endocytosis via clathrin-coated pits is a well-understood process; however, clathrin also assembles into large, flat clathrin lattices (FCLs), which remain poorly described. Quantitative electron, ...

TL;DR: An enquiry into why “rod colour” should be blue, together with an examination of the similarities and dissimilarities of rods and “blue cones”, leads to the further suggestion that rods and "blue cones" exist separately but share a neural pathway.

TL;DR: The arrangement of dislocations in the dislocation network has been studied in various conditions, namely annealed, cold-worked, recovered and after creep as mentioned in this paper, and there is convincing evidence for the idea that at many of these intersections two Ω(1/2)-dislocations join to make one dislocation.
Abstract: The arrangement of the dislocations has been studied in iron in various conditions, namely annealed, cold-worked, recovered and after creep. In all conditions the dislocation network is characterized by attractive intersections where two dislocations join to make one dislocation, and there is convincing evidence for the idea that at many of these intersections two $\frac{1}{2}$a$\langle111\rangle$ dislocations join to make one a$\langle100\rangle$ dislocation. These attractive intersections are thought to contribute substantially to the flow stress. These are also repulsive intersections but according to calculation they constitute weaker obstacles to flow than the attractive junctions.
