Two highly fluorescent 4-alkylamino-
N-allyl-1,8-naphthalimide dyes have been synthesised and their basic photophysical properties in ethanol and toluene solution have been determined. Synthesis and ...characterization of new side-group copolymers of styrene with the fluorescent 1,8-naphthalimide have been described. It has been established that 0.90–0.92% of the dyes are chemically bonded to the polymer chain. The absorption and fluorescent characteristics of copolymers in toluene and in the solid state are discussed.
The present study describes the infrared characterization of some newly synthesized photoactive poly(amidoamine) dendrimers, whose peripheries have been modified with 1,8-naphthalimides. Main ...attention is being paid to the effect that different substituents at C-4 position of the naphthalene ring have upon the dendrimers polarization. Infrared studies have shown that the dendrimer generations have similar polarizations as the dendrimer molecules wherein no intermolecular hydrogen bonds occur.
A measurement of the Higgs boson mass is presented based on the combined data samples of the ATLAS and CMS experiments at the CERN LHC in the H→γγ and H→ZZ→4ℓ decay channels. The results are obtained ...from a simultaneous fit to the reconstructed invariant mass peaks in the two channels and for the two experiments. The measured masses from the individual channels and the two experiments are found to be consistent among themselves. The combined measured mass of the Higgs boson is m_{H}=125.09±0.21 (stat)±0.11 (syst) GeV.

The use of semantic information necessitates a quantitative assessment of the information in general. This article will provide an overview and analysis of the present state of semantic information ...measurement as methods and algorithms for semantic data reduction. We propose an algorithm combining initial information classification, knowledge enrichment through keywords, identification of potential semantic correlations between them, and semantic information extraction.
In this short note we present results of background measurements carried out with polystyrene based cast plastic 12.0×12.0×3.0 cm

size scintillator counter with a wavelength shifting fibre and a ...multi-pixel Geiger mode avalanche photodiode readout in the Baksan underground laboratory at a depth of 200 metres of water equivalent. The total counting rate of the scintillator counter measured at this depth and at a threshold corresponding to ∼0.37 of a minimum ionizing particle is approximately 1.3 Hz.
When a droplet hits the surface of water, it is often observed that a water column, or ‘back‐jet’, surges upwards. Counterintuitive though it might be, a similar phenomenon can occur when ultrafast ...light pulses shine on a nanostructured metal surface. These sub‐wavelength ‘nanojets’ occur in the regions of highest local field enhancements. For more details, see the article by V. K. Valev et al. on page OP29.
A series of new bis-1,8-naphthalimide derivatives has been synthesized and the FT-IR and UV/vis absorption characteristics discussed. Substituents effect on the IR spectral characteristics have been ...investigated. A new polyimide with a 1,8-naphthalimide unit main chain has been synthesized.
