However, for creating models of egg-laying behavior in recent neural biology studies on the nematode Caenorhabditis elegans, the authors have found that homogeneous Poisson processes are inadequate to capture the measured temporal patterns. They present here a novel three-state model that effectively represents the measured temporal patterns and that correlates well with the cellular and molecular mechanisms that are known to be responsible for the measured behavior. Although the model involves a combination of two Poisson processes, it is surprisingly tractable. The authors derive closed-form expressions for the probabilistic and statistical properties of the model and present several parameter estimation procedures including a maximum likelihood algorithm. Both simulated and experimental results are illustrated. The experiments with measured data show that the egg-laying patterns fit the three-state model very well. The model also may be applicable in quantifying the link between other neural processes and behavior or in other situations where discrete events occur in clusters.","PeriodicalId":240431,"journal":{"name":"Conference Record of the Thirty-First Asilomar Conference on Signals, Systems and Computers (Cat.

A laser source directs a pulse of narrowband optical radiation into the atmosphere. As the pulse propagates, it irradiates small aerosol particles, which scatter radiation back toward the lidar system. Because the aerosol particles are small enough to be borne by the wind, the frequency of the scattered radiation is Doppler shifted as a result of motion toward or away from the lidar. Measurement of this Doppler shift provides an estimate of the radial wind component, while computation of the power in the backscattered radiation gives insight into the atmospheric turbidity, presence of aerosol layers or clouds, and attenuation. Pulsed Doppler lidar systems have been used in a number of meteorological applications. Deployment of a Doppler lidar on an Earth-orbiting satellite has been proposed to remotely measure tropospheric winds on a global scale. In a large number of these applications, lidar system performance, impact, and maximum range is limited by weak backscattered signals present at the lidar receiver. Because potential methods of improving signal-to-noise ratio can be technically infeasible and/or very expensive, optimizing signal processing of the lidar return to improve performance at very low signal levels has received significant attention. In the remainder of this paper, we describe techniques for processing Doppler lidar returns from weak and fluctuating signals, and discuss system design tradeoffs to obtain maximum performance.","PeriodicalId":240431,"journal":{"name":"Conference Record of the Thirty-First Asilomar Conference on Signals, Systems and Computers (Cat.
