Dual VP Classes
No full textWe consider the complexity class ACC1 and related families of arithmetic circuits. We prove a variety of collapse results, showing several settings in which no loss of computational power results if fan-in of gates is severely restricted, as well as presenting a natural class of arithmetic circuits in which no expressive power is lost by severely restricting the algebraic degree of the circuits. We draw attention to the strong connections that exist between ACC1 and VP, via connections to the classes CC1[m] for various m. These results tend to support a conjecture regarding the computational power of the complexity class VP over finite algebras, and they also highlight the significance of a class of arithmetic circuits that is in some sense dual to VP. In particular, these dual-VP classes provide new characterizations of ACC1 and TC1 in terms of circuits of semiunbounded fan-in. As a corollary, we show that ACCi = CCi for all i 1.The earlier conference paper version of this article is available from the publisher at http://link.springer.com/book/10.1007%2F978-3-662-48054-0 and also from the Rutgers institutional repository: http://dx.doi.org/doi:10.7282/T3KK9DN4.Peer reviewe

Antibacterial Properties of Nanoparticles: A Comparative Review of Chemically Synthesized and Laser-Generated Particles
No full textNanomaterials have recently received an enormous amount of attention from the scientific community due to their outstanding activity relative to bulk materials. This increase in activity relative to bulk materials can be attributed to the high surface area to volume ratio associated with nanoparticles. Nanoparticles have found applications in almost every field of science. Currently there is significant interest in the development of nanoparticles as antibacterial agents. This work is paramount due to the increasing number of antibiotic-resistant strains of bacteria. Nanoparticles can be synthesized using various methods, each with their own advantages and disadvantages, and the method is often chosen based on the intended application. This review will cover the most prevalent method, chemical-based reduction of salts, and a fairly new laser-based method that holds tremendous promise in nanoparticle synthesis. We conclude with a comparison of the antimicrobial activities of materials made via each method.Peer reviewe

Irradiation with visible light enhances the antibacterial toxicity of silver nanoparticles produced by laser ablation
No full textThe rise of antibiotic-resistant bacteria is a rapidly growing global health concern. According to the Center for Disease Control, approximately 2 million illnesses and 23,000 deaths per year occur in the USA due to antibiotic resistance. In recent years, there has been a surge in the use of metal nanoparticles as coatings for orthopedic implants, wound dressings, and food packaging, due to their antimicrobial properties. In this report, we demonstrate that the antibacterial efficacy of silver nanoparticles (AgNPs) is enhanced with exposure to light from the visible spectrum. We find that the increased toxicity is due to augmented silver ion release and bacterial uptake. Interestingly, silver ion toxicity does not appear to depend on the formation of reactive oxygen species. Our findings provide a novel paradigm for using light to regulate the toxicity of AgNPs which may have a significant impact in the development of new antimicrobial therapeutics.Peer reviewe

Seabed foraging by Antarctic krill: Implications for stock assessment, bentho-pelagic coupling, and the vertical transfer of iron
No full textA compilation of more than 30 studies shows that adult Antarctic krill (Euphausia superba) may frequent benthic habitats year-round, in shelf as well as oceanic waters and throughout their circumpolar range. Net and acoustic data from the Scotia Sea show that in summer 2-20% of the population reside at depths between 200 and 2000 m, and that large aggregations can form above the seabed. Local differences in the vertical distribution of krill indicate that reduced feeding success in surface waters, either due to predator encounter or food shortage, might initiate such deep migrations and results in benthic feeding. Fatty acid and microscopic analyses of stomach content confirm two different foraging habitats for Antarctic krill: the upper ocean, where fresh phytoplankton is the main food source, and deeper water or the seabed, where detritus and copepods are consumed. Krill caught in upper waters retain signals of benthic feeding, suggesting frequent and dynamic exchange between surface and seabed. Krill contained up to 260 nmol iron per stomach when returning from seabed feeding. About 5% of this iron is labile, i.e., potentially available to phytoplankton. Due to their large biomass, frequent benthic feeding, and acidic digestion of particulate iron, krill might facilitate an input of new iron to Southern Ocean surface waters. Deep migrations and foraging at the seabed are significant parts of krill ecology, and the vertical fluxes involved in this behavior are important for the coupling of benthic and pelagic food webs and their elemental repositories
