Introduction: The aim of this study was to evaluate the effect of proximal contour of class II composite restorations placed with straight or contoured matrix band using composite resins with different modulus of elasticity on stress distribution by finite element method. Methods: In order to evaluate the stress distribution of class II composite restorations using finite element method, upper ...

This work is dedicated to joint image restoration and contour detection considering the Ambrosio-Tortorelli functional. Two proximal alternating minimization schemes with convergence guarantees are provided, PALM-AT SL-PAM-AT, as well closed-form expressions of involved proximity operators. A thorough numerical study conducted in order evaluate performance both comparisons state-of-the-art Mumf...

A variety of operations have been described in recent years that are intended as digital solutions to a basic class of cartographic adjacency problems. A selection of these algorithms includes: interpolation; Voronoi diagrams of point distributions (proximal maps, Thiessen polygons); skeleton encoding (of scanned characters or polygons); corridor selection, or extraction of regions within speci...

PURPOSE The purpose of this study was to determine whether radiographically demonstrated proximal stent graft contour can be used as a marker for security of proximal neck fixation after endovascular aneurysm repair. METHODS Stent graft structure was examined in 100 consecutive patients with abdominal aortic aneurysms who were treated with the stent graft. Stent graft integrity, stent contour...

To optimize plant architecture (e.g., photosynthetic active leaf area, leaf-stem ratio), plant physiologists and plant breeders rely on destructively and tediously harvested biomass samples. A fast and non-destructive method for obtaining information about different plant organs could be vehicle-based spectral proximal sensing. In this 3-year study, the mobile phenotyping platform PhenoTrac 4 w...

spontaneous coronary artery dissection is a rare cause of acute coronary syndrome and sudden cardiac death. we report coronary artery dissection in a 36-year-old woman with retrosternal chest pain 2 weeks after abortion. electrocardiography showed st elevation in leads v2-v4 and st depression in the inferior leads. lab data were normal. cardiac catheterization showed a suspicious thrombotic les...

Aim Interdental stripping is a common clinical procedure in orthodontic therapy, by reshaping the proximal contacts. Handheld abrasive strips have been criticized as time-consuming process. Metallic strip system, diamond disk, or segment disks have become increasingly popular. The aim of this study is to evaluate the morphological aspects of remodeled dental surfaces so as to conclude which of ...
