The parrotfish Sparisoma choati is described from the tropical eastern Atlantic Ocean. It is genetically unique and also differs from its congeners by coloration as follows: initial phase individuals and females greyish brown to greyish red, with chin and belly paler and reddish brown scales irregularly distributed along flanks resulting in a general mottled appearance; terminal phase individua...

This study investigates the relative importance of region of origin associated with extrinsic (price, brand, promotion) and intrinsic (grape, type of wine, colour, age, special references) cues in the decision of final consumers and small retailers to buy Portuguese quality wine. In order to attain this goal we conducted a survey through face-to-face interviews in the Minho region. The results ...

We report on the development and deployment of 11.3 tons of 0.1% Gd loaded liquid scintillator used in the Palo Verde reactor neutrino oscillation experiment. We discuss the chemical composition, properties and stability of the scintillator elaborating on the details of the scintillator preparation crucial for obtaining a good scintillator quality and stability.

We use the Simon, Verde, & Jimenez (2005) determination of the redshift dependence of the Hubble parameter to constrain cosmological parameters in three dark energy cosmological models. We consider the standard ΛCDM model, the XCDM parameterization of the dark energy equation of state, and a slowly rolling dark energy scalar field with an inverse power-law potential. The constraints are restric...

Dynamic program optimization is the only recourse for optimizing compilers when machine and program parameters necessary for applying an optimization technique are unknown until runtime. With the movement toward portable parallel programs, facilitated by language standards such as OpenMP, many of the optimizations developed for high-performance machines can no longer be applied prior to runtime...

This paper explores the consequences of sabotage for the design of incentive contracts. The possibility of sabotage gives rise to a dynamic concern, similar to the Ratchet effect, which distorts the agents’ incentives. We first show that the mere possibility of sabotage may make it impossible to implement the first-best effort, and then offer two distinct incentive schemes, fast track and late ...

The use of reconfiguration of field programmable gate arrays (FPGAs) to improve the area efficiency of a class of FPGA circuits is reported. The applicability of the technique to a large class of general-purpose applications is established by identifying the key characteristics of suitable circuits. The development of a new design methodology that allows the technique to be reliably deployed wi...

Complex robotic tasks such as autonomous exploration and grasping demand the co-operation of sensors and actuators. In order to integrate sensor measurements and actuator control schemes we must determine the rigid body transformations that relate the native co-ordinate frames of these devices. Equivalently, we need to estimate the relative pose of sensors and actuators in the system. We examin...

We give an axiomatic foundation to the updating rule proposed by [Sarin, R. and Wakker, P. P. (1998). Revealed likelihood and knightian uncertainty. Journal of Risk and Uncertainty 16(3):223-250.] for CEU preferences. This rule is dynamically consistent but non-consequentialist, since forgone consequences are relevant for conditioning. Whereas it does not work universally, but only when counter...

As integrated circuit line widths continue to shrink, there is a corresponding increase in the capital costs of microelectronic fabrication plants and in the mask making costs of individual chips. As a result, it is increasingly uneconomical to produce small and medium volume chips in the latest submicron technologies. Reconfigurable logic circuits, such as FPGAs (field programmable gate arrays...
