Policy competition in clean technology: Scaling up or innovating up?

Clean up or go crazy

A utophagy is needed to clear up dementia-inducing proteins from the cell, report Filimonenko et al. During autophagy, the cell gobbles up its own internal components into membranous structures called autophago-somes, which fuse with multivesicular bodies (MVBs) before delivery to lysosomes, where the sequestered material is degraded. Autophagy is particularly important at times of cell stress ...

Scaling - Up or Out

Insatiable demands for performance and the availability of inexpensive microprocessors have led to the development of multiprocessor-based systems. Passionate debates amongst architects, designers, and vendors continue to rage regarding cost effective multiprocessor design alternatives. Hypes and claims of performance and scalability are confusing and often misleading. Increasing performance an...

Scaling up HIV self-testing in sub-Saharan Africa: a review of technology, policy and evidence

PURPOSE OF REVIEW HIV self-testing (HIVST) can provide complementary coverage to existing HIV testing services and improve knowledge of status among HIV-infected individuals. This review summarizes the current technology, policy and evidence landscape in sub-Saharan Africa and priorities within a rapidly evolving field. RECENT FINDINGS HIVST is moving towards scaled implementation, with the r...

Scaling Up

Most analytical and experimental results on evolutionary programming (EP) are obtained using low-dimensional problems, e.g., smaller than 50. It is unclear, however, whether the empirical results obtained from the low-dimensional problems still hold for high-dimensional cases. This paper investigates the behaviour of four diierent EP algorithms for large-scale problems, i.e., problems whose dim...
