Reconstructions of the (110) surface of rutile TiO2 (the dominant surface of this important mineral and catalyst) are investigated using the evolutionary approach, resolving previous controversies. Depending on thermodynamic conditions, four different stable reconstructions are observed for this surface. We confirm the recently proposed "Ti2O3-(1×2)" and "Ti2O-(1×2)" reconstructions and predict...

A marked bend in the Hawaiian-Emperor seamount chain supposedly resulted from a recent major reorganization of the plate-mantle system there 50 million years ago. Although alternative mantle-driven and plate-shifting hypotheses have been proposed, no contemporaneous circum-Pacific plate events have been identified. We report reconstructions for Australia and Antarctica that reveal a major plate...

A general, model-free, quantitative approach to the key morphological properties of a porous polymer monolith is presented. After 3D reconstruction, image-based analysis delivers detailed spatial and spatially correlated information on the structural heterogeneities in the void space and the polymer skeleton. Identified heterogeneities, which limit the monolith's performance in targeted applica...

We present a numerical image-formation model for investigating the influence of partial coherence, sample thickness and depth-of-focus on the accuracy of tomographic reconstructions in transmission x-ray microscopes. The model combines wave propagation through the object by finite difference techniques with Fourier methods. We include a ray-tracing model to analyse the origin of detrimental str...

Penile and urethral reconstructive surgical procedures are used to treat a variety of urologic diagnoses. Urethral stricture disease can lead to progressive lower urinary tract symptoms and may require multiple surgical procedures to improve patient's symptoms. Male stress urinary incontinence is associated with intrinsic sphincter deficiency oftentimes associated with radical prostatectomy. Me...

Reconstruction of the external ear is a challenging problem encountered by plastic surgeons. Causes deformities can be various etiologies (human bites, animal fights, burns, infections, accidents, or even sports injuries). Full-thickness defects, which cannot treated approximating wound edges, show good results with Antia-Buch’s chondro-cutaneous flaps. A 34-year-old male presented history huma...

Objective: To improve the surgical results of neurosurgical patients with complex defects and deformities head based on modern innovative technologies. Маterials methods. Based analysis diagnosis treatment 54 common extracerebral tumors issues optimizing their were considered. The positive role reconstructive-plastic operations in basis possibilities computer modeling use arterial autografts is...

Philadelphia, Pa. Learning Objectives: After studying this article, the participant should be able to: 1. Identify the diagnostic criteria and clinical features of body dysmorphic disorder. 2. Describe the prevalence of body dysmorphic disorder in cosmetic populations. 3. Identify appropriate treatment strategies for body dysmorphic disorder. Background: Body dysmorphic disorder is a relatively...

BACKGROUND Fournier's gangrene is an acute and potentially lethal necrotising fasciitis that involves the scrotum and perineum. This disease can result in the loss of skin and soft tissue. To repair the scrotal and perineal defects remains a surgical challenge. METHODS Between January 2000 and December 2008, 50 patients were admitted to our hospital with a diagnosis of Fournier's gangrene. We...
