PURPOSE To characterize abnormalities in three-dimensional optic nerve head (ONH) morphology in people with albinism (PWA) using spectral-domain optical coherence tomography (SD-OCT) and to determine whether ONH abnormalities relate to other retinal and clinical abnormalities. METHODS Spectral-domain OCT was used to obtain three-dimensional images from 56 PWA and 60 age- and sex-matched contr...

Background: Conveying instructions is an everyday use of language, and gestures are likely to be a key feature of this. Although co-speech iconic gestures are tightly integrated with language, and people with aphasia (PWA) produce procedural discourses impaired at a linguistic level, no previous studies have investigated how PWA use co-speech iconic gestures in these contexts. Aims: This study ...

AIDS stigma refers to prejudice and discrimination directed at people or groups perceived to have HIV/AIDS (Herek, 1999). Although AIDS stigma has been found in adolescent and adult populations, few researchers have explored it among children. Misconceptions about people with AIDS (PWA) might lead to negative attitudes toward PWA and obstruct HIV prevention efforts. The authors assessed 110 Pue...

(48%) did not. The wPWA group experienced an average decrease in PWA of 25 points compared to baseline (95% CI[22–28] p<0.001). The control group experienced an average increase in PWA of 8 points compared to baseline (95% CI[5–10] p<0.001). Based on univariate analysis, we fitted a predictive multivariable logistic regression model including race, depression, hypertension, BMI, bilateral recon...

We give an overview of our recent results on model predictive control (MPC) for a class of non-smooth hybrid systems subject to perturbations. More specifically, we consider continuous and non-continuous piecewise-affine (PWA) systems. Most results on MPC for PWA systems involve non-perturbed systems. In this paper we consider perturbed PWA systems with bounded disturbances, i.e., PWA systems w...

Results of the ηππ and ωω final state partial wave analysis(PWA) are presented. The mass-independent and the mass-dependent PWA were performed. The ηππ system PWA results in the observation of the resonances in the J = 1, 3, 2 and 4 waves. The results of the ωω system PWA confirms the existence of the f2(1565) and f4(2050). The f2(1950) is observed. There is evidence for a f4(2300) meson.

We present an algorithm for generating a binary search tree that allows efficient computation of piecewise affine (PWA) functions defined on a polyhedral partition. This is useful for PWA control approaches, such as explicit model predictive control (MPC), as it allows the controller to be implemented on-line with small computational effort. The computation time is logarithmic in the number of ...
