Abstract: Ants can navigate over long distances between their nest and food sites using visual cues [1, 2]. Recent studies show that this capacity is undiminished when walking backward while dragging a heavy food item [3-5].… read more here.

Abstract: A high-efficiency X-band overmoded relativistic backward-wave oscillator (RBWO) using a nonuniform slow-wave structure (SWS) and cavity resonant reflector (RR) is designed in order to increase the beam–wave interaction efficiency. The electrodynamic SWS is a sinusoidally… read more here.

DOI: 10.1186/s13662-018-1728-2
Abstract: In this paper, we consider a backward problem for a space-fractional diffusion equation. This problem is ill-posed, i.e., the solution does not depend continuously on the data. The optimal error bound for the problem under… read more here.
