background: this study investigated the protective effects of aqueous extracts of anogeissus leiocarpus (dc) guill & perr (combretaceae) and terminalia avicennioides guill & perr (combretaceae) root barks, as well as their 1:1 (w/w) mixture on liver redox and haematological parameters of diethylnitrosamine-treated rats. methods: rats were orally administered distilled water, diethylnitrosamine ...

ecological destruction in human-dominated landscapes has significant impacts on environment sustainability internationally. landscape planning can play a role in mitigating the effects of human-related activities. one element of landscape planning involves the analysis of the biological, spatial and social arrangement of areas in an urban environment and identifying characteristics that are und...

*This research was funded by DARPA through SPAWAR under Grant No. N ABSTRACT In this paper we explore the use of nonlinear Teager Energy Operator based features derived from multiresolution sub-band analysis for classification of emotional/stressful speech. We propose a novel scheme for automatic sub-band weighting in an effort towards developing a generic algorithm for understanding emotion or...

This paper presents a pattern recognition-based scheme for detection of islanding conditions in synchronous- based distributed generation (DG) systems. The main idea behind the proposed scheme is the use of spatial features of system parameters such as the frequency, magnitude of positive sequence voltage, etc. In this study, the system parameters sampled at the point of common coupling (PCC) w...

The two most striking features of Alzheimer disease are (i) the multitude of abnormalities affecting essentially every system and (ii) the strict age dependence. Recent work suggests that both features are linked to increased oxidative stress that damages lipids, proteins and nucleic acids and results in redox-active metal accumulations, mitochondrial damage and formation of advanced glycation ...

We define a new notion of satisfaction of a temporal logic formula φ by a behavior w. This notion, denoted by (w, t, t′) |= φ, is characterized by two time parameters: the position t from which satisfaction is considered, and the end of the (finite) behavior t′ which indicates how much do we know about the behavior. We define this notion in dense time where φ is a formula in the future fragment...

Large-scale environmental patterns in the Humboldt Current System (HCS) show major changes during strong El Niño episodes, leading to the mass mortality of dominant species in coastal ecosystems. Here we explore how these changes affect the life-history traits of the surf clam Mesodesma donacium. Growth and mortality rates under normal temperature and salinity were compared to those under anoma...
