Retraction of 'Vibrational evidence for the "missing link" in structural kinship between kanemite and FSM-16 mesoporous silica' by Ewa M. Serwicka, et al., Dalton Trans., 2016, DOI: 10.1039/C6DT01600F.

The pyranosyl ring in the title compound, C(16)H(18)O(5)S, adopts an envelope conformation, with the acetyl groups in equatorial positions. In the crystal, weak C-H⋯O inter-actions link the molecules into chains.

In the title compound, C(12)H(16)ClO(4)P, the phospho-nate ring adopts a chair conformation. In the crystal, intermolecular O-H⋯O hydrogen bonds link the molecules into chains propagating along the b axis.

We experimentally demonstrate successful performance of VCSEL-based WDM link supporting advanced 16-level carrierless amplitude/phase modulation up to 1.25 Gbps, over 26 km SSMF with spectral efficiency of 4 bit/s/Hz for application in high capacity PONs.

In the title mol-ecular salt, C(6)H(16)N(+)·NO(2) (-), the cation forms two N-H⋯O hydrogen bonds to nearby nitrite anions which link the ionic units into chains propagating along the b-axis direction.

In the title compound, C(16)H(13)ClO(3), the dihedral angle between the benzene rings is 80.74 (8)°. In the crystal, C-H⋯O hydrogen bonds link the mol-ecules to form C(11) chains propagating in [010].

The mitochondrial DNA of the trypanosomatid Crithidia fasciculata consists of thousands of copies of a 2.5 kb minicircle and a small number of 37kb maxicircles catenated into a single enormous network. Treatment of C. fasciculata with the type II DNA topoisomerase inhibitor VP16 produces cleavable complexes of a type II DNA topiosomerase with both minicircles and maxicircles. A combined Souther...

1. Abstract This document gives a brief description of a UMTS WCDMA iterative multi-user receiver previously presented in [1],[2] using various modulation schemes. The main advantage is the great increase in spectral efficiency in both up-link and downlink environments with mixed data rate users. The paper focuses on higher order modulation as well as on the performance of mixed data rate scena...

Recent study in wireless sensor networks (WSN) has found that the irregular link quality is a common phenomenon. The irregular link quality, especially link asymmetry, has significant impacts on the design of WSN protocols, such as MAC protocols, neighborhood and topology discovery protocols, and routing protocols. In this paper, we propose asymmetryaware link quality services, including the ne...
