3-Nitrobenzanthrone (3-NBA) has been isolated from diesel exhaust and airborne particles and identified as a potent direct-acting mutagen in vitro and genotoxic agent in vivo. In order to evaluate the in vivo toxicity and carcinogenicity of 3-NBA in a situation corresponding to inhalation, a combined short-term and lifetime study with intratracheal (i.t.)(More)
The carcinogenic vehicle emission product 3-nitrobenzanthrone (3-NBA) is known to rearrange in the atmosphere to the isomer 2-nitrobenzanthrone (2-NBA), which exists in 70-fold higher concentration in ambient air. The genotoxicity of 2-NBA and 3-NBA was studied both in vitro (human cell lines A549 and HepG2) and in vivo (F344 female rats intra-tracheally(More)
3-Nitrobenzanthrone (3-NBA) is an urban air pollutant and rat lung carcinogen that is among the most potent mutagens yet tested in the Salmonella reversion assay. In the present study, 1 mg 3-NBA was administered orally to female F344 rats and DNA adduct formation was examined in liver, lung, kidney and five sections of the gastrointestinal (GI) tract at 6(More)
In this paper we propose an accurate state of charge (SOC) estimation method for a lithium-ion battery for hybrid electric vehicle (HEV) and electric vehicles (EV) use. Although it is important to accurately determine the SOC of a battery to achieve maximum efficiency and safety, none of the existing methods has achieved this perfectly. To address this(More)
Vulnerability of children to toxic substances is of great concern due to their susceptibility and specific exposure profiles. In this study, we examined urinary 1-hydroxypyrene (1-OHP) levels in 134 kindergarten children and their mothers in order to assess exposure profiles from foods. Mean concentration of 1-OHP in children (0.083 micromol/mol-creatinine)(More)
The purpose of this work is to enable risk-limiting electricity dispatch through a market mechanism. There has been a solid body of work on centralized risk-limiting dispatch, which guarantees that the risk of energy shortage is within a user-specified bound. The current trading mechanism of a day-ahead electricity market can be viewed as a market that(More)
In this paper we propose a new event-triggered scheme for nonlinear continuous-time systems with additive bounded disturbances. Unlike existing results, the proposed event-triggered strategy is not derived from Lyapunov stability analysis. Instead, it is obtained from the time interval when the state reaches a local region around the origin. By guaranteeing(More)
In this paper, we propose an aperiodic formulation of Model Predictive Control for distributed agents with additive bounded disturbances. In the proposed method, each agent solves an Optimal Control Problem only when certain control performances cannot be guaranteed according to certain triggering rules. This could lead to the reduction of energy(More)
