The history of life is fi lled with examples of one species diverging into several, even thousands, each with unique traits geared to the demands of its ecological niche. In the textbook case of adaptive radiation, an ancestral fi nch species landed on the Galapagos Islands just a few million years ago, and evolved into 13 new species with specialized beaks adapted to exploiting the various see...

While Wi-Fi 5 is still sufficient for many organizations and businesses, it important to consider upgrade 6. This article discusses the main differences between The goal identify key metrics transmission of information content signals, a method determining best use signals certain categories use, an analysis study influence frequencies on quality transmitted information, also analyzes growth ra...

We report on the discovery and rationale to devise bright single optical eigenmodes that feature quantum-optical mode volumes of about $1\text{ }\text{ }{\mathrm{nm}}^{3}$. Our findings rely development application a quasinormal theory self-consistently treats fields electron nonlocality, spill-out, Landau damping around atomistic protrusions metallic nanoantenna. By outpacing with radiation vi...

An increasing number of studies have investigated the effects of different types of corrective feedback. However, doubts have been raised whether field (in)dependent (FI/FD) L2 learners benefit differently from the explicit type of corrective feedback (i.e., metalinguistic). This study examined the (possible) effects of metalinguistic feedback on FI/FD intermediate L2 learners’ writing accuracy...

In the paper (Theoret. Comput. Sci. 237 (2000)) Anderson present a theorem which characterizes any semiretract S by means of two retracts R and R!: The /rst part of the paper contains a counterexample for this characterization. Then some results are presented which /nally lead to the theorem which determines for a given semiretract S the minimal number of retracts R1; : : : ; Rm such that the e...
