Marine methylotrophic bacteria that consumed methyl bromide (MeBr) and/or dunethyl sulfide (DMS) were isolated: 4 strains from Long Island Sound, USA (LIS) and 1 from the tropical North Atlantic (TNA). Substrates used for enrichment were DMS, trimethylarnine (TMA) or TMA plus MeBr. Attempts to obtain isolates on MeBr as the sole source of carbon and energy were unsuccessful. Three of the isolat...

Amphiphilic block copolymers poly(LysAA-b-DMS) consisting of a hydrophilic poly(N-α-acrylamide-L-lysine) [poly(LysAA)] segment with different molecular weights and a hydrophobic polydimethylsiloxane (PDMS) segment were prepared as follows. The precursor copolymer poly(Boc-LysAA-OtBu-b-PDMS) was obtained from radical polymerization of N-α-acrylamide-N-ε-tert-butoxycarbonyl-L-lysine-tert-butylest...

Abstract. Dimethyl sulfide (DMS) is a naturally occurring aerosol precursor gas which plays an important role in the global sulfur budget, formation and climate. While DMS produced predominantly by phytoplankton, recent observational literature has suggested that corals their symbionts produce comparable amount of DMS, unaccounted for models. It further been hypothesised coral reef source may m...

The oxidation of dimethyl sulfide (DMS) is key for the natural sulfate aerosol formation and its climate impact. Multiphase chemistry an important pathway but neglected in current chemistry-climate models. Here, DMS aerosol-chemistry-climate model ECHAM-HAMMOZ extended to include multiphase methane sulfonic acid (MSA) deliquesced particles, parameterized by reactive uptake. First simulations ag...

Tutte has shown that every 4-connected planar graph contains a Hamilton cycle. Grünbaum and Nash-Williams independently conjectured that the same is true for toroidal graphs. In this paper, we prove that every 4-connected toroidal graph contains a Hamilton path.

Dechow, Myers, and Shakespeare (DMS, 2009) find a negative relation between income from securitization activities and income from non-securitization activities. DMS interprets this finding as indicating that managers use the flexibility available in fair value accounting rules to smooth earnings. We clarify the role of fair value in accounting for asset securitizations, discuss alternative expl...

We experimentally demonstrate linear bandgap guidance of optical vortices as high-gap defect modes (DMs) in two-dimensional induced photonic lattices. We show that donut-shaped vortex beams can be guided in a tunable negative (lower-index) defect, provided that the defect strength is set at an appropriate level. Such vortex DMs have fine features in the "tails" associated with the lattice aniso...

This paper asks what classes of input signals are sufficient in order to completely identify the input/output behavior of generic bilinear systems. The main results are that step inputs are not sufficient, nor are single pulses, but the family of all pulses (of a fixed amplitude but varying widths) do suffice for identification.

Drosophila myosuppressin (TDVDHVFLRFamide; DMS) and sulfakinin (FDDYGHMRFamide; DSK) have similar C-terminal structures. To determine the neuronal expression patterns of these structurally related peptides, we have generated DMS- and DSK-specific antisera to multiple antigenic peptides and performed double-label immunochemistry with antisera raised on different animals of the same species host ...

To overcome the shortcomings of standard particle swarm optimization algorithm (PSO), such as premature convergence and low precision, a dynamic multi-swarm PSO with global detection mechanism (DMS-PSO-GD) is proposed. In DMS-PSO-GD, whole population divided into two kinds sub-swarms: several same-sized sub-swarms sub-swarm. The achieve information interaction sharing among themselves through r...
