Previous research on the relation between working memory capacity (WMC) and shooting behavior suggests that individuals with low working memory spans are more prone to shooting errors than are individuals with high working memory spans. The present study investigated how WMC interacts with the proportion of “shoot” to “don’t shoot” decisions to affect overall shooting performance. Participants ...

This paper presents a rapid hierarchical radiosity algorithm for illuminating scenes containing large polygonal patches. The algorithm constructs a hierarchical representation of the form factor matrix by adaptively subdividing patches into subpatches according to a user-supplied error bound. The algorithm guarantees that all form factors are calculated to the same precision, removing many comm...

This work mainly focuses on the influence from switches of shooting angles in videos during the cognitive processing in the human brain. In the experiment we used the videos with switches of shooting angles as materials and compared the ERPs elicited by the switch frames and the non-switch frames in the videos, it was found that when subjects were asked to pay attention to the video contents, t...

The range of unseen instances that can be successfully classiied by a learning algorithm is determined not only by the distribution of the training data, but also by the parameters of the function to be learned. With the right parameters, learning in a certain region of the state space can generalize to completely diierent areas with no retraining. We demonstrate the power of using well-chosen ...

The current pilot study aimed at providing an initial assessment of how anxiety influences police officers' shooting behavior. Seven police officers participated and completed an identical shooting exercise under two experimental conditions: low anxiety, against a non-threatening opponent, and high anxiety (HA), against a threatening opponent who occasionally shot back using colored soap cartri...

This paper deals with the shooting algorithm for optimal control problems with a scalar control and a regular scalar state constraint. Additional conditions are displayed, under which the so-called alternative formulation is equivalent to Pontryagin’s minimum principle. The shooting algorithm appears to be well-posed (invertible Jacobian), iff (i) the no-gap second order sufficient optimality c...

The parareal algorithm is a method to solve time-dependent problems parallel in time: it approximates parts of the solution later in time simultaneously to parts of the solution earlier in time. In this paper the relation of the parareal algorithm to space-time multigrid and multiple shooting methods is first briefly discussed. The focus of the paper is on new convergence results that show supe...

I read with great interest the article entitled ‘Significant differences when using creatinine, modification of diet in renal disease, or cystatin C for estimating glomerular filtration rate in ICU patients’ by Lipcsey et al. (1) in the March 2011 issue of the Upsala Journal of Medical Sciences. This article provides an interesting analysis of estimating renal function in critically ill patient...

In a sample with known levels of preshooting posttraumatic stress (PTS) symptoms, we examined the impact of a campus mass shooting on trajectories of PTS in the 31 months following the shooting using latent growth mixture modeling. Female students completed 7 waves of a longitudinal study (sample sizes ranged from 812 to 559). We identified 4 distinct trajectories (n = 660): (a) minimal impact-...
