Using Sat solvers for synchronization issues in partial deterministic automata [PDF]

, 2019
We approach the task of computing a carefully synchronizing word of minimum length for a given partial deterministic automaton, encoding the problem as an instance of SAT and invoking a SAT solver.

Interfacial chemical oxidative synthesis of multifunctional polyfluoranthene. [PDF]

, 2015
A novel polyfluoranthene (PFA) exhibiting strong visual fluorescence emission, a highly amplified quenching effect, and widely controllable electrical conductivity is synthesized by the direct cationic oxidative polymerization of fluoranthene in a ...

DFAs and PFAs with Long Shortest Synchronizing Word Length

, 2017
It was conjectured by \v{C}ern\'y in 1964, that a synchronizing DFA on $n$ states always has a shortest synchronizing word of length at most $(n-1)^2$, and he gave a sequence of DFAs for which this bound is reached.

Per- and polyfluoroalkyl substances (PFAS) in wastewater streams: occurrence and current treatment

Academia Engineering, 2023
PFAS are a growing environmental concern due to their persistence and universality. PFAS enter the environment through multiple channels, one of which is wastewater.

Omnipresent Chemicals: TSCA Preemption in the Wake of PFAS Contamination [PDF]

, 2020
Over the past few decades, studies addressing the harms of PFAS have gradually progressed, and now scientists believe increased exposure could lead to reproductive defects and a higher risk of cancer.

Adsorption analysis of PFOA on activated carbon and ion-exchange resin: A comparative study using four isotherm models [PDF]

Journal of the Serbian Chemical Society
Per- and polyfluoroalkyl substances (PFAS), known as “forever chemicals”, are highly persistent environmental pollutants due to their strong carbon–fluorine bonds.

Emerging and legacy PFAS and cytokine homeostasis in women of childbearing age

Scientific Reports, 2022
Per- and polyfluoroalkyl substances (PFAS) are widespread chemicals. Legacy PFAS have been phased out of production in most developed countries and emerging PFAS (short-chain PFAS and polyfluorinated compounds) are used as legacy PFAS alternatives.

Current exposure of Italian women of reproductive age to PFOS and PFOA: a human biomonitoring study [PDF]

, 2015
Perfluorooctane sulfonate (PFOS) and perfluorooctanoic acid (PFOA) concentrations were determined in serum samples collected in 2011-2012 from 549 nulliparous Italian women of reproductive age who resided in six different Italian Regions.
