When watching the image of a natural scene on a computer screen, observers initially move their eyes toward the center of the image-a reliable experimental finding termed central fixation bias. This systematic tendency in eye guidance likely masks attentional selection driven by image properties and top-down cognitive processes. Here, we show that the central fixation bias can be reduced by del...

Despite evidence for the role of group membership in the neural correlates of social cognition, the mechanisms associated with processing non-verbal behaviors displayed by racially ingroup vs. outgroup members remain unclear. Here, 20 Caucasian participants underwent fMRI recording while observing social encounters with ingroup and outgroup characters displaying dynamic and static non-verbal be...

Inclusion of clouds in an initial condition has been a long-term goal of many numerical weather prediction systems. The work with the ARPS model and ADAS initialization has been a notable example (Xue, et al., 2000). Work by Crook and Sun, 1997 has taken this even into the realm of the model adjoint. What we seek in this work is an a 3-D static analysis that can provide the kind of sophisticati...

When watching the image of a natural scene on a computer screen, observers initially move their eyes towards the center of the image — a reliable experimental finding termed central fixation bias. This systematic tendency in eye guidance likely masks attentional selection driven by image properties and top-down cognitive processes. Here we show that the central fixation bias can be reduced by d...

Results: (1) On the initial orienting indicators (direction of initial gaze and initial fixation latency) and the initial attention maintenance indicators (first fixation duration), the RD patients showed no attentional bias toward the emotional faces; (2) For the late-stage attention maintenance indicators (total fixation time), both the RD group and the HC group exhibited attentional bias tow...

We consider a spherically symmetric (purely magnetic) SU(2) Yang-Mills field propagating on an ultrastatic spacetime with two asymptotically hyperbolic regions connected by a throat of radius α. Static solutions in this model are shown to exhibit an interesting bifurcation pattern in the parameter α. We relate this pattern to the Morse index of the static solution with maximal energy. Using a h...

Fixed effects estimators of nonlinear panel models can be severely biased due to the incidental parameters problem. In this paper I find that the most important component of this incidental parameters bias for probit fixed effects estimators of index coefficients is proportional to the true value of these coefficients, using a large-T expansion of the bias. This result allows me to derive a low...
