Coverage and adoption of altmetrics sources in the bibliometric community
Stefanie Haustein, Isabella Peters, Judit Bar-Ilan +3
Altmetrics, indices based on social media platforms and tools, have recently emerged as alternative means of measuring scholarly impact. Such indices assume that scholars in fact p…
Word equations in simple groups and polynomial equations in simple algebras
Alexey Kanel-Belov, Boris Kunyavskii, Eugene Plotkin
We give a brief survey of recent results on word maps on simple groups and polynomial maps on simple associative and Lie algebras. Our focus is on parallelism between these theorie…
Staggered-Ladder Quasienergy Spectra for Generic Quasimomentum and Quantum-Dynamical Manifestations
Itzhack Dana
A new kind of regular quasienergy (Floquet) spectrum is found for the generalized kicked particle under quantum-resonance conditions at generic quasimomentum, a quantity most relev…
Infinitesimals, Imaginaries, Ideals, and Fictions
David Sherry, Mikhail G. Katz
Leibniz entertained various conceptions of infinitesimals, considering them sometimes as ideal things and other times as fictions. But in both cases, he compares infinitesimals fav…
Thermally assisted current-induced magnetization reversal in SrRuO3
Yishai Shperber, Omer Sinwani, Netanel Naftalis +3
We inject a sequence of 1 ms current pulses into uniformly magnetized patterns of the itinerant ferromagnet SrRuO3 until a magnetization reversal is detected. We detect the effecti…
The John-Nirenberg inequality with sharp constants
Andrei K. Lerner
We consider the one-dimensional John-Nirenberg inequality: $$ |\{x\in I_0:|f(x)-f_{I_0}|>\a\}|\le C_1|I_0|\exp\Big(-\frac{C_2}{\|f\|_{*}}\a\Big). $$ A. Korenovskii found that the s…
