The tear trough ligament: anatomical basis for the tear trough deformity.

BACKGROUND The exact anatomical cause of the tear trough remains undefined. This study was performed to identify the anatomical basis for the tear trough deformity. METHODS Forty-eight cadaveric hemifaces were dissected. With the skin over the midcheek intact, the tear trough area was approached through the preseptal space above and prezygomatic space below. The origins of the palpebral and o...

Differential Privacy Trough Knowledge Refinement

We introduce a novel mechanism to attain differential privacy. Contrary to the common mechanism based on the addition of a noise whose magnitude is proportional to the sensitivity of the query function, our proposal is based on the refinement of the user’s prior knowledge about the response. We show that our mechanism has several advantages over noise addition: it does not require complex compu...

2 00 7 A closed parabolic trough solar collector

Parabolic trough[1] is the most mature technology for large scale exploitation of solar energy. Several power plants based on this technology have been operational for years, and more are being built. However, the current technology suffers from a too high installation cost. This high cost makes it very hard to compete economically with fossil energy without government subsidies, compromising t...
