Let K n be the cone of positive semideenite n n matrices and let A be an aane subspace of the space of symmetric matrices such that the intersection K n \ A is non-empty and bounded. Suppose that n 3 and that codim A = ? r+2 2 for some 1 r n?2. Then there is a matrix X 2 K n \A such that rank X r. We give a short geometric proof of this result, use it to improve a bound on realizability of weig...

Colorectal cancer (CRC) is the third most common neoplasm in Turkey and in the world and their incidence has increased in recent years (Jemal et al., 2010; Karaca et al., 2011). At diagnosis, 30-40 per cent of colorectal cancer patients have metastatic disease. For patients with advanced colorectal cancer treatment is usually palliative and mainly consists of systemic chemotherapy (Scheithauer ...

Wenyao XU Fengbo REN Background on process variation and Leakage With technology scaling, the MOS device channel length is reduced. As the channel length approaches the source-body and drain-body depletion widths, the charge in the channel due to these parasitic diodes become comparable to the depletion charge due to the MOS gate-body voltage [Poon et al. 1973], rendering the gate and body term...

On the complexity of the st-connectivity problem Chung Keung Poon Doctor of Philosophy 1996 Department of Computer Science University of Toronto The directed st-connectivity problem is fundamental to computer science. There are many applications which require algorithms to solve the problem in small space and preferably in small time as well. Furthermore, its space and time-space complexities a...

iii ACKNOWLEDGEMENTS I would first like to thank my advisor Dr. Stephen Long for the opportunity to study here at UCSB. The graduate circuits courses he offered provided me with valuable foundation much needed to pursue this work. Special thanks goes to Hugh Finlay and Dr. Ken Weller at Skyworks Solutions for their support, encouragement, and technical advice. Thanks goes to my friends and coll...

Congenital hypothyroidism is the most common endocrine disease in infants. Through early identification and treatment of affected patients, delays in cognitive and motor development can be effectively prevented. In this topical update, Dr Liz Yuen reviews the aetiology and shares recent advances in understanding the molecular basis of congenital hypothyroidism. Genetic diagnosis and counselling...
