Recent advances in the integrated modeling of ELMy H-mode plasmas are presented. A model for the H-mode pedestal and for the triggering of ELMs predicts the height, width, and shape of the H-mode pedestal and the frequency and width of ELMs. Formation of the pedestal and the L-H transition is the direct result of ~ Er × ~ B flow shear suppression of anomalous transport. The periodic ELM crashes...

Purpose. To introduce a clinical sign on spectral domain optical coherence tomography (SDOCT), which may indicate high risk for full-thickness macular hole formation after internal limiting membrane (ILM) peeling. Methods. The preoperative SDOCT images of two patients-one with multilaminar hemorrhage from ruptured retinal artery macroaneurysm and one with serous retinal detachment and severe ma...

A tape peeling model based on the geometry of the peel zone (PZ) is derived to predict the peeling behavior of adhesive tapes at peel angles less than or equal to 90o. The PZ model adds an angle-dependent multiplier to the ‘Kendall equation’ that takes into account the geometrical changes within the peel zone. The model is compared to experimental measurements of the peel force at different ang...

OBJECTIVE To examine whether hand contamination with fruit results in a false blood glucose (BG) reading using capillary fingertip blood sample. RESEARCH DESIGN AND METHODS The study subjects were healthy volunteers with normal glucose tolerance test. Capillary BG samples were collected from the fingertip after peeling orange, grape, or kiwi fruit, followed by no action, washing hands with ta...

PURPOSE Two cases with optic disc pit associated maculopathy, treated with vitrectomy surgery with internal limiting membrane peeling (ILM) and gas tamponade, are presented. METHODS Interventional case reports. RESULTS Two patients with serous macular detachment associated with a congenital optic pit underwent vitrectomy surgery, induction of posterior vitreous detachment, peeling of the IL...

The collapse of abandoned room-and-pillar mines is often violent and unpredictable. Safety concerns often resulted in mine closures with no post-mining stability evaluations. As a result, large amounts of land resources over room-and-pillar mines are wasted. This paper attempts to establish an understanding of the long-term stability issues of goafs (abandoned mines). Considering progressive pi...

Motivated by recent studies on reversible adhesion mechanisms of geckos and insects, we investigate the effect of pre-tension on the orientation-dependent adhesion strength of an elastic tape adhering on a substrate. Our analysis shows that the pre-tension can significantly increase the peel-off force at small peeling angles while decreasing it at large peeling angles, leading to a strongly rev...

R ecently, enzymatic vitrectomy has been applied to macular hole (MH) repair. A clinical trial indicated that 40% of MH cases could be treated with a single injection of ocriplasmin (Jetrea, ThromboGenics).1 These results are exciting, but the remaining 60% of patients still require surgery, specifically pars plana vitrectomy (PPV) and internal limiting membrane (ILM) peeling for hole repair. I...

The future development of polymer composite materials with nanotubes or nanoscale fibers requires the ability to understand and improve the interfacial bonding at the nanotube–polymer matrix interface. In recent work [Strus MC, Zalamea L, Raman A, Pipes RB, Nguyen CV, Stach EA. Peeling force spectroscopy: exposing the adhesive nanomechanics of one-dimensional nanostructures. Nano Lett 2008;8(2)...

The inner limiting membrane (ILM) is the basement membrane of the Müller cells and can act as a scaffold for cellular proliferation in the pathophysiology of disorders affecting the vitreomacular interface. The atraumatic removal of the macular ILM has been proposed for treating various forms of tractional maculopathy in particular for macular pucker. In the last decade, the removal of ILM has ...
