On the optimal management of a class of aquatic ecological-economic systems
(Elsevier Science. The definitive version can be found at http://www.elsevier.com/locate/dsw, 2001)This paper studies aquatic ecological-economic systems such as the Chesapeake Bay. The stability of such ecological-economic systems depends on the successful functioning of a small number of generalist species in a wide ... -
On the scarcity value of ecosystem services
(Elsevier, 2003)In this exploratory paper, we first make a case for considering the scarcity value of ecosystem services in the analyses of jointly determined ecological–economic systems. Next, we point out that insight into the scarcity ... -
On Understanding the relationship between ultrasound speckle and the scattering microstructure
(Acoustical Imaging, 1997)Recent studies on the statistics of the envelope of the ultrasound echo signal from a random scattering medium suggest that the statistical moments of the signal may carry quantitative information about the scattering ... -
Ontogenetic change in blood oxygen capacity and maximum activity in garter snakes (Thamnophis sirtalis)
(Springer: Journal of Comparative Physiology B: Biochemical, Systemic, and Environmental Physiology, 1977-01)There is an ontogenetic increase in the time that garter snakes (Thamnophis s. sirtalis) can maintain maximum activity at 25°C. Newborn snakes are exhausted by 3–5 min of activity while adults can be active for 20–25 min. ... -
Ontogenetic change in molecular and functional properties of blood of garter snakes, Thamnophis sirtalis
(Wiley: Journal of Experimental Zoology, 1977-07)At birth the blood of garter snakes (Thamnophis sirtalis) has high oxygen affinity (P50 at 25°C and pH 7.2 = 21 mm Hg), low hematocrit (14%), and a high proportion of inactive hemoglobin (44%). Growth of the snakes is ... -
Open source for accounting and enterprise systems
(2007-11)This chapter introduces open source software (OSS) for accounting and enterprise information systems It covers the background. functions, maturity models, adoption issues, strategic considerations, and future trends for ... -
Optical Fourier and Hartley transform adaptive filters
(Microwave and optical technology letters, 2004-01-05)Optical signal-processing architectures are presented to realize frequency-domain implementations of the classical least-mean-square (LMS) adaptive-filtering algorithm. Optical implementation of both Fourier and Hartley ... -
Optical processor for adaptive arrays
(Elsevier - Optics Communications, 1990-06)Two novel architectures for implementing the LMS algorithm optically are introduced. Convergence of the LMS algorithm is analyzed and the effect of the analog inaccuracies are considered. -
Optical, electrical, and structural properties of sputtered aluminum alloy thin films with copper, titanium and chromium additions
(Elsevier - Thin Solid Films, 2007-02)Aluminum alloys containing copper, chromium, and titanium were sputter deposited with the goal of maintaining the high bulk reflectance of aluminum while providing surface topography more suited for optical applications. ... -
Optimal nonlinear estimation of linear stochastic systems: The Multivariable extension

An Optimal stopping approach to the conservation of biodiversity
(Elsevier. The definitive version can be found at http://www.elsevier.com, 1998)In the past two decades, a considerable amount of concern has been expressed in academic and nonacademic circles about the decline in the world's diverse biological resources. Recently, Swanson (in: Biodiversity Loss: ... -
Optimised isolation procedure for biologically active compounds nimbolide and 28-deoxonimbolide from Azadirachta indica leaves
(Elsevier: Phytochemistry, 1999-12)Alpha-linolenic acid has been isolated from fresh A. indica leaves and an optimised procedure for the isolation of the limonoids nimbolide and 28-deoxonimbolide is described. -
Optimization of microchannel geometry for direct chip cooling using single phase heat transfer
(American Society of Mechanical Engineers (ASME), 2004-06)Direct cooling of an electronic chip of 25mm x 25mm in size is analyzed as a function of channel geometry for single-phase flow of water through small hydraulic diameters. Fully developed laminar flow is considered ... -
Orf135 from Escherichia coli is a nudix hydrolase specific for CTP, dCTP, and 5-methyl-dCTP
(The American Society for Biochemistry and Molecular Biology:, 2001-02-23)Orf135 from Escherichia coli is a new member of the Nudix (nucleoside diphosphate linked to some other moiety, x) hydrolase family of enzymes with substrate specificity for CTP, dCTP, and 5-methyl-dCTP. The gene has been ... -
Orf186 represents a new member of the nudix hydrolases, active on adenosine(5)triphospho(5)adenosine, ADP-ribose, and NADH
(The American Society for Biochemistry and Molecular Biology: Journal of Biological Chemistry, 1998-02-06)Orf186, a new member of the Nudix hydrolase family of genes, has been cloned and expressed, and the protein has been purified and identified as an enzyme highly specific for compounds of ADP. Its three major substrates are ... -
An organism-specific method to rank predicted coding regions in Trypanosoma brucei
(Oxford University Press: Nucleic Acids Research, 2003)Genome annotation in differently evolved organisms presents challenges because the lack of sequence-based homology limits the ability to determine the function of putative coding regions. To provide an alternative to ... -
Organizing for radical innovation: an exploratory study of the structural aspects of RI management systems in large established firms
