Cardiology is about flow. The primary purpose of the cardiovascular system is to drive, control, and maintain blood flow to all parts of the body. Flow dictates the form and function of the heart and blood vessels through ontogenic and phylogenic development, the structural and functional consequence of repair, and in its end stages, remodeling and response to failure. Flow should therefore be ...

Increasingly, automatic restoration is an indispensable security measure in control systems (e.g. those used in critical infrastructure sectors) due to the importance of ensuring the functionality of monitoring infrastructures. Modernizing the interconnection of control systems to provide interoperability between different networks, at a low cost, is also a critical requirement in control syste...

“OF MAKING MANY BOOKS THERE IS NO END,” writes the biblical author of Ecclesiastes—and so it seems that of the making of many international heritage conventions, principles, and guidelines there also seems to be no end in sight. Beginning with the 1931 Athens Charter for the Restoration of Historic Monuments, through the 1964 Venice Charter, and continuing with the recent adoption of the 2003 I...

Ocean engineering has a strong need for clear and high quality underwater images. Capturing a clear scene underwater is not a trivial task since color cast and scattering caused by light attenuation and absorption are common. The poor quality hinders the automatic segmentation or analysis of the images. In this work, an image restoration based on compressive sensing is reported which tackles wi...

Fracture healing is a complex physiological process. With the latest advances made in molecular biology and genetics it is now known that it involves the spatial and temporal coordinated action of several different cell types, proteins and the expression of hundreds of genes working towards restoring its structural integrity without scar formation. The standard tissue engineering approach to pr...

This work addresses the problem of blind image deblurring, that is, of recovering an original image observed through one or more unknown linear channels and corrupted by additive noise. We resort to an iterative algorithm, belonging to the class of Bussgang algorithms, based on alternating a linear and a nonlinear image estimation stage. In detail, we investigate the design of a novel nonlinear...

introduction: coronal microleakage may significantly reduce the prognosis of endodontic treatment. temporary restorative materials have a crucial role in preventing the infection of root canals between and after endodontic treatment. this in vitro study was designed to evaluate the coronal microleakage of three temporary restorative materials used in endodontics: coltosol, cavisol and cina. mat...

background. hemostatic agents are applied to prepare an isolated bleeding-free condition during dental treatments and can influence adhesive restorations. this study evaluated the effect of a hemostatic agent (viscostat) on microleakage of contaminated dentinal margin of class v composite resin restorations with three adhesives. methods. sixty freshly extracted human molars were selected and cl...

intra-city natural structures have always had a key role in creating sustainable urban greenspaces. adapting to natural features and relating the intra-city greenspaces to such natural structures as river-valleys, hillsides, lakes and forests, guarantee the endurance, sustainability and longevity of the natural quality of city. this paper looks at intra-city natural structures which have underg...

introdouction: overhang refers to the extension of restoration material from the cavity. it has an important role in decay, plaque accumulation and periodontal disease, so the aim of this study is determining the frequency of restoration overhang in patients in anzali, guilan. materials and methods: this descriptive cross-sectional study was completed using 293 patients who visited for routine ...
