The space of static finite-energy configurations in the electroweak theory admits a Z2 topological structure. More precisely, we show that this space contains two disconnected sectors of unstable gauge-Higgs fields odd under a properly defined generalized parity. This classification extends the description of baryon and lepton number violating electroweak processes to the symmetric phase of the...

A highly chlorinated flame retardant, Dechlorane Plus (DP), was detected and identified in ambient air, fish, and sediment samples from the Great Lakes region. The identity of this compound was confirmed by comparing its gas chromatographic retention times and mass spectra with those of authentic material. This compound exists as two gas chromatographically separable stereoisomers (syn and anti...

Selected organochlorine pesticides (OCs) and halogenated flame retardants (HFRs) were analyzed in surficial fjord sediments collected down the length of Kongsfjorden, Svalbard in the Norwegian high Arctic. Hexachlorocyclohexane (α-HCHs) was found to be the most abundant OC in the sediment, followed by BDE-209>chlordane>α-endosulfan>Dechlorane Plus (anti-DP)>trifluralin concentration ranges were...

We present a comparison between the published optical, IR and CO spectroscopic redshifts of 86 (sub-)mm galaxies and their photometric redshifts as derived from long-wavelength (radio–mm–FIR) photometric data. The redshift accuracy measured for 13 sub-mm galaxies with at least one robustlydetermined colour in the radio–mm–FIR regime and additional constraining upper limits is ∆z ≈ 0.30. This ac...

This paper presents an effective design methodology and flow, which is validated through three mmwave/sub-mm-wave amplifiers: including W-band LNA with NF=7dB, W-band PA with PAE >11% and D-band amplifier with gain>20dB. The CMOS based amplifiers can be integrated with III-V materials to form heterogeneous integration, such as COSMOS, to achieve the best performance for various applications.

Due to close proximity urban development, mangroves exposed the contamination of polybrominated diphenyl ethers (PBDEs). Decabromodiphenyl ether (BDE-209) is one most predominant PBDE congener. The present study aimed investigate toxic effects BDE-209 on antioxidative and non-antioxidative responses Kandelia obovata , a very common mangrove species, under different concentrations BDE-209, 0.1, ...
