Over the last 20 years, a large number of instruments have provided plasma density measurements in Earth's topside ionosphere. To utilize all collected observations for empirical modeling, it is necessary to ensure that they do not exhibit systematic differences and are adjusted same reference frame. In this study, we compare satellite from Gravity Recovery Climate Experiment (GRACE), Constella...

A recent article in this journal by Roll et al (2008 Nanotechnology 19 045703) presents experimental results of the temperature dependence of dissipation in dynamic force microscopy which they use to elucidate the mechanisms of such a dissipation signal in the PTCDA on KBr system. We argue here that dissipation results are often highly dependent upon the tip structure, and urge caution in the i...

A mixture of propositional dynamic logic and epistemic logic that we call PDL + E is used to give a formalization of Artemov’s knowledge based reasoning approach to game theory, (KBR), [4, 5, 6, 7]. Epistemic states of players are represented explicitly and reasoned about formally. We give a detailed analysis of the Centipede game using both proof theoretic and semantic machinery. This helps ma...

Pressing solid barbituric acid with KBr to prepare samples for IR spectroscopy leads to the formation of an ionic co-crystal, in which the co-former is a classical ionic salt; co-crystal formation is also obtained with the other alkali bromides (LiBr, NaBr, RbBr and CsBr) and with caesium iodide. The simultaneous presence of alkali and halide ions affects the dissolution properties of barbituri...

— The temperature dependence of the optical absorption bands and of the magnetic circular dichroism are measured for the Au" centre in KBr and RbCl. The data are analyzed with the method of moments by using six electron-lattice interaction coefficients to describe the coupling of the | 1 r l u > and | Tlu > excited states with the AXg, Eg and T2g lattice modes. The centre is found to be coupled...
