In a plenary session at ASCO 2015, Brown et al. presented the results of Alliance NCCTG N0574, a phase 3 trial comparing whole-brain radiation therapy (WBRT) plus radiosurgery (SRS) to SRS alone in patients with 1 to 3 brain metastases, each <3 cm, by contrast magnetic resonance imaging (MRI). The primary endpoint was cognitive progression (CP), defined as decline >1 standard deviation (SD) fro...

In this paper we establish a fundamental link between the search for weighing matrices constructed from two circulants and the operation of sorting strings, an operation that has been studied extensively in computer science. In particular, we demonstrate that the search for weighing matrices constructed from two circulants using the power spectral density criterion and exploiting structural pat...

There is abundant evidence for widespread microbial activity in deep continental fractures and aquifers, with important implications for biogeochemical cycling on Earth and the habitability of other planetary bodies. Whitman et al. (P Natl Acad Sci USA, 95, 1998, 6578) estimated a continental subsurface biomass on the order of 10(16) -10(17) g C. We reassess this value in the light of more rece...

In the area of mass production, the products are weighed using load cell based weighing system. A load cell is an uncontrollable weighing device. Improvement in filtering increases the speed of weighing and enhances the measurement accuracy. In this paper, a novel algorithm and architecture is proposed for the weighing system. The algorithm has been verified and implemented in the weight measur...
