OBJECTIVE This study investigated the prevalence of fecal incontinence (FI) and urinary incontinence (UI) in primiparous postpartum Chinese women. STUDY DESIGN Questionnaires about FI and UI symptoms were completed via telephone interviews conducted within 6 months postpartum. RESULTS A total of 1889 primiparous postpartum women were asked to(More)
BACKGROUND Central venous catheterization (CVC) is associated with patient risks known to be inversely related to clinician experience. We developed and evaluated a performance assessment tool for use in a simulation-based central line workshop. We hypothesized that instrument scores would discriminate between less experienced and more experienced(More)
In this article, we propose techniques for modeling and rendering of heterogeneous translucent materials that enable acquisition from measured samples, interactive editing of material attributes, and real-time rendering. The materials are assumed to be optically dense such that multiple scattering can be approximated by a diffusion process described by the(More)
Existing solid texture synthesis algorithms generate a full volume of color content from a set of 2D example images. We introduce a new algorithm with the unique ability to restrict synthesis to a subset of the voxels, while enforcing spatial determinism. This is especially useful when texturing objects, since only a thick layer around the surface needs to(More)
BACKGROUND Many patients with acute lung injury (ALI) and acute respiratory distress syndrome (ARDS) have had recent healthcare interventions prior to developing ALI/ARDS. OBJECTIVE To determine the timing of ALI/ARDS onset in relation to hospital admission and other healthcare interventions. METHODS We conducted a population-based observational cohort(More)
Figure 1: Relighting results using the light transport matrix reconstructed by our method. Complex light transport effects, including caustics (a), complex occlusions (b), and a mixture of caustics, complex occlusions, inter-reflections, and subsurface scattering (c) are all faithfully reproduced. Abstract We propose a kernel Nyström method for(More)
We introduce a vector representation called <i>diffusion curve textures</i> for mapping diffusion curve images (DCI) onto arbitrary surfaces. In contrast to the original <i>implicit</i> representation of DCIs [Orzan et al. 2008], where determining a single texture value requires iterative computation of the entire DCI via the Poisson equation, diffusion(More)
PURPOSE Structured opportunities for learning communication, teamwork and laparoscopic principles are limited for urology residents. We evaluated and taught teamwork, communication and laparoscopic skills to urology residents in a simulated operating room. MATERIALS AND METHODS Scenarios related to laparoscopy (insufflator failure, carbon dioxide(More)
Full-field optical coherence tomography (FF-OCT) using a conventional light-emitting diode and a complementary metal-oxide semiconductor camera has been developed for characterising coatings on small pellet samples. A set of en-face images covering an area of 700 × 700 μm(2) was taken over a depth range of 166 μm. The three-dimensional structural(More)
Although studies involving the circadian response to external time cues indicate that the peripheral clocks are dominated mainly by food cues, whether and how changes in the light and food cues affect the circadian rhythm of the renal clock is still largely unknown. In the present study, we found that the circadian phases of Bmal1, Clock, Cry1, Per1, and(More)
