The thermal conductivity (κ) of suspended graphene membranes made by chemical vapor deposition (CVD) was measured by micro-Raman mapping. Cracks and wrinkles present in these suspended graphene membranes were identified by micro-Raman mapping, and κ values and their statistics were obtained on membranes free of such imperfections in a single mapping. Based on this new technique, an average κ va...

Necrobiotic xanthogranuloma is a rare disease characterized by indurated nodules and yellowish-red plaques in the dermis or subdermal tissues particularly in the periorbital region; the lesions are often ulcerated. This disease is frequently associated with hematological disorders such as monoclonal gammopathy and lymphoproliferative disorders. Its pathogenesis is unknown and the small number o...

Wrinkles are an extremely important contribution for enhancing the realism of human figure models. In this paper, we present an approach to generate static and dynamic wrinkles on human skin. For the static model, we consider micro and macro structures of the skin surface geometry. For the wrinkle dynamics, an approach using a biomechanical skin model is employed. The tile texture patterns in t...

The wrinkled geometry of thin films is known to vary appreciably as the applied stresses exceed their buckling threshold. Here we derive and analyze a minimal, nonperturbative set of equations that captures the continuous evolution of radial wrinkles in the simplest axisymmetric geometry from threshold to the far-from-threshold limit, where the compressive stress collapses. This description of ...

A 54-year-old man presented to the emergency department with a Glasgow Coma Score of 8 after throwing himself out of a window. Right periorbital and conjunctival blood infiltration were noted, with complete ophthalmoplegia and loss of the pupillary light reflex. On the third day, a systolic bruit became audible over the right eyeball [(Figure 1A) Click on image for audio]. The CT with contrast ...

purpose : to review periocular dermoid cysts to determine distribution of demographic factors, and tumor location methods : in this retrospective, observational case series in a tertiary-care hospital, we reviewed all cases of histopathologically verified periocular dermoid cysts at our institution between 2003 and 2011. the study endpoints included: age, gender, and tumor location. results : t...

We present a lightweight non-parametric method to generate wrinkles for 3D facial modeling and animation. The key lightweight feature of the method is that it can generate plausible wrinkles using a single low-cost Kinect camera and one high quality 3D face model with details as the example. Our method works in two stages: (1) offline personalized wrinkled blendshape construction. Userspecific ...

Wrinkles, folds, creases and other elastic surface instabilities play a crucial role in many systems in nature and engineering. While surface instabilities of ideal bilayer structures with large contrasts in elastic stiffness are well understood, many natural and man-made structures are far from this ideal. To better understand the behavior of systems with modest stiffness contrast, in particul...

BACKGROUND Upper eyelid dermatochalasis is typically treated with excisional blepharoplasty. The role of the CO2 laser previously had been confined to that of a vaporizing, incisional, or hemostatic tool. Over the past several years, however, ablative CO2 laser skin resurfacing has been popularized as an adjunctive treatment to blepharoplasty to minimize periorbital rhytides through its vaporiz...
