Effects of a surface topography composite with puerariae radix on human STRO-1-positive stem cells [PDF]
, 2010 Human skeletal stem cells (STRO-1 positive/STRO-1+) respond to different topographical features in various ways. On a flat surface these cells spread and tend to develop a fibroblast-like morphology.

A novel radix-3/9 algorithm for type-III generalized discrete Hartley transform
, 2006 A novel radix-3/9 algorithm for type-III generalized discrete Hartley transform (GDHT) is proposed, which applies to length-3(P) sequences. This algorithm is especially efficient in the case that multiplication is much more time-consuming than addition ...

Combined Radix-10 and Radix-16 Division Unit
, 2007 In this work we extend a previously proposed digit-recurrence radix-10 division unit to be able to perform also radix-16 division. The extension is simplified by the fact that in the radix-10 implementation the quotient digit is decomposed into two parts

An asynchrobatic, radix-four, carry look-ahead adder [PDF]
, 2008 A low-power, Asynchrobatic (asynchronous, quasi-adiabatic), sixteen-bit, radix-four, parallel-prefix adder circuit is presented. The results show that it is an efficient, low power design, and that as would be expected with an asynchronous design, its ...
