Image watermarking refers to the process of embedding an authentication message, called watermark, into the host image to uniquely identify the ownership. In this paper a novel, intelligent, scalable, robust wavelet-based watermarking approach is proposed. The proposed approach employs a genetic algorithm to find nearly optimal positions to insert watermark. The embedding positions coded as chr...

• Atherosclerotic renovascular stenosis is a potentially progressive disease. • Risk factors for progressive stenosis and renal artery occlusion include: – uncontrolled systolic hypertension (>160 mmHg) – diabetes mellitus – high grade (>70%) ipsilateral and contralateral atherosclerotic renal vascular disease (ARVD), and – significant baseline proteinuria. • Risk factors for atrophy include: –...

the present paper investigates the advantages of a new class of composite grid structures over conventional grids. thus far, a known grid structure such as orthogrid or isogrid has been used as an orthotropic layer with at most in-plane anisotropy. the present laminated grid is composed of various numbers of thin composite grid layers. the stiffness of the structure can be adjusted by choosing ...

There are many reasons for the health inequities that we see around the world today. Public policy and the way society organises its affairs affects the economic, social and physical factors that influence the conditions in which people are born, grow, live, work and age - the social determinants of health. Tackling health inequities is a political issue that requires leadership, political cour...

IMPORTANCE Although approximately 30% to 50% of patients experience a complete response after regional chemotherapy for in-transit melanoma, a subset of patients will develop rapidly progressive disease. In the current era of an expanding armamentarium, including both regional and systemic options for treating advanced melanoma, identifying perioperative factors that predict disease progression...
