Unary probabilistic and quantum automata on promise problems

, 2015
We continue the systematic investigation of probabilistic and quantum finite automata (PFAs and QFAs) on promise problems by focusing on unary languages. We show that bounded-error QFAs are more powerful than PFAs. But, in contrary to the binary problems,

On the use of the proximity force approximation for deriving limits to short-range gravitational-like interactions from sphere-plane Casimir force experiments [PDF]

, 2009
We discuss the role of the proximity force approximation in deriving limits to the existence of Yukawian forces - predicted in the submillimeter range by many unification models - from Casimir force experiments using the sphere-plane geometry.

Analytical Methods and Optimization of Pretreatment Processes for Short- and Medium-Chain and Novel Perfluoro/Polyfluoroalkyl Substances in Water

Yankuang ceshi
With the production and use of long-chain per- and polyfluoroalkyl substances (PFAS) being restricted, short- and medium-chain as well as new alternative PFAS have been widely detected in water environments, and their ecological and health risks have ...

Legacy and alternative per- and polyfluoroalkyl substances in the U.S. general population: Paired serum-urine data from the 2013–2014 National Health and Nutrition Examination Survey

Environment International, 2019
Concerns are heightened from detecting environmentally persistent man-made per- and polyfluoroalkyl substances (PFAS) in drinking water systems around the world.

Per- and Polyfluoroalkyl Substances (PFAS): History, Current Concerns, and Future Outlook

Molecules
Per- and polyfluoroalkyl substances (PFAS) involve multiple per- and polyfluorinated compounds that are widely used globally. Legacy PFAS, including PFOA, PFOS, and PFHxS, were manufactured before 2000 in various industrialized nations, then gradually ...

Using Plant Functional Attributes to Quantify Site Productivity and Growth Patterns in Mixed Forests [PDF]

, 1997
Forest growth models are one of several important prerequisites for sustainable management. The complexity of tropical moist forest means that there is often little objective information to classify sites and species for growth modelling and yield ...

Effects of compost and digestate on environment and plant production – results of two research projects [PDF]

, 2008
A yearly amount of 9.3x106t compost and digestate derived from separately collected organic waste is produced in the 25 European Union member states. The improvement of soil properties is a major benefit of compost application.

Binary and quaternary mixtures of perfluoroalkyl substances (PFAS) differentially affect the immune response to influenza A virus infection

Journal of Immunotoxicology
Per- and polyfluoroalkyl substances (PFAS) are anthropogenic organofluorine compounds that persist indefinitely in the environment and bioaccumulate throughout all trophic levels.
