TL;DR: In this paper, the two-dimensional light distribution of a galaxy is reconstructed using Fourier series fits to azimuthal profiles computed in concentric elliptical annuli centered on the galaxy.
Abstract: We use automated surface photometry and pattern classification techniques to morphologically classify galaxies. The two-dimensional light distribution of a galaxy is reconstructed using Fourier series fits to azimuthal profiles computed in concentric elliptical annuli centered on the galaxy. Both the phase and amplitude of each Fourier component have been studied as a function of radial bin number for a large collection of galaxy images using principal-component analysis. We find that up to 90% of the variance in many of these Fourier profiles may be characterized in as few as three principal components and that their use substantially reduces the dimensionality of the classification problem. We use supervised learning methods in the form of artificial neural networks to train galaxy classifiers that detect morphological bars at the 85%-90% confidence level and can identify the Hubble type with a 1 σ scatter of 1.5 steps on the 16 step stage axis of the revised Hubble system. Finally, we systematically characterize the adverse effects of decreasing resolution and signal-to-noise ratio on the quality of morphological information predicted by these classifiers.

TL;DR: The sensor described here is sensitive enough to detect concentrations as low as nanomoles per liter of a chemical species, with a dynamic range of more than 6 orders of magnitude.
Abstract: We propose and demonstrate the possibility of using a permanently microbent bare optical fiber for detecting chemical species. Two detection schemes, viz., a bright-field detection scheme (for the core modes), and a dark-field detection scheme (for the cladding modes) have been employed to produce a fiber-optic sensor. The sensor described here is sensitive enough to detect concentrations as low as nanomoles per liter of a chemical species, with a dynamic range of more than 6 orders of magnitude.

TL;DR: In this article, the authors address two issues pertaining to legal pluralism in capture fisheries, particularly with regard to the South, and conclude that co-management is a process that brings legal systems and their constituent organizations and groups together within a single framework.
Abstract: This paper addresses two issues pertaining to legal pluralism in capture fisheries, particularly with regard to the South. First there is the problem of analysis. If legal pluralism is a common phenomenon, how is it to be discerned and understood? Secondly, there is the matter of institutional design: given the pervasiveness of legal pluralism, which management institutions are better suited to represent and resolve inter-legal system differences? The authors argue the case of co-management. Drawing on examples and insights from a comparative research project in South Asia, four basic types of legal pluralism and co-management are distinguished. The authors conclude that co-management is a process that brings legal systems, and their constituent organizations and groups, together within a single framework. For fisher organizations, which frequently have distinct legal perspectives, co-management is an essential path to legitimacy. For the state, other legal systems are a resource that management can draw upon.
