TL;DR: Comparison of the results with the outcome of three-dimensional finite-difference time domain calculations allows us to identify small imperfections in the structure that result in the spatial modification of the intensity distribution.
Abstract: By using scanning near-field optical microscopy, we directly map the subwavelength confinement of light around a point defect in a two-dimensional photonic crystal microresonator. Comparison of our results with the outcome of three-dimensional finite-difference time domain calculations allows us to identify small imperfections in the structure that result in the spatial modification of the intensity distribution.

TL;DR: In this paper, the authors give asymptotic upper and lower bounds for the number of squarefree d (0 < d ≤ X) such that the equation x 2 - dy 2 = -1 is solvable.
Abstract: We give asymptotic upper and lower bounds for the number of squarefree d (0 < d ≤ X) such that the equation x 2 - dy 2 = -1 is solvable. These estimates, as usual, can equivalently be interpreted in terms of real quadratic fields with a fundamental unit with norm -1 and give strong evidence in the direction of a conjecture due to P. Stevenhagen.

TL;DR: This paper presents a simple local medium access control protocol, called JADE, for multi-hop wireless networks with a single channel that is provably robust against adaptive adversarial jamming and achieves an asymptotically optimal throughput if there is a sufficiently dense distribution of nodes.
Abstract: This paper presents a simple local medium access control protocol, called JADE, for multi-hop wireless networks with a single channel that is provably robust against adaptive adversarial jamming. The wireless network is modeled as a unit disk graph on a set of nodes distributed arbitrarily in the plane. In addition to these nodes, there are adversarial jammers that know the protocol and its entire history and that are allowed to jam the wireless channel at any node for an arbitrary (1 - e)-fraction of the time steps, where 0 < e < 1 is an arbitrary constant. We assume that the nodes cannot distinguish between jammed transmissions and collisions of regular messages. Nevertheless, we show that JADE achieves an asymptotically optimal throughput if there is a sufficiently dense distribution of nodes.
