Recent Topics in Protein Folding

A review of recent advances in ab initio protein folding by the Folding@home project

The Folding@home project harnesses a volunteer distributed computing network to perform ab initio molecular simulations of protein folding. Thanks to engineering innovations like a Graphical Processing Unit (GPU) client for running simulations, Folding@home is able to harness over 6.1 petaFLOPS of processing power, allowing it to simulate longer and more complex protein folding mechanisms than ...

Recent advances in RNA folding.

In the realm of nucleic acid structures, secondary structure forms a conceptually important intermediate level of description and explains the dominating part of the free energy of structure formation. Secondary structures are well conserved over evolutionary time-scales and for many classes of RNAs evolve slower than the underlying primary sequences. Given the close link between structure and ...

Recent topics in NMR imaging and MRI.

NMR and NMR imaging (MRI) are finding increasing use not only in the clinical and medical fields, but also in material, physicochemical, biological, geological, industrial and environmental applications. This short review is limited to two topics: (i) new techniques and pulse sequences and their application to non-clinical fields that may have clinical application; and (ii) new trends in MR con...

Recent Topics in Power Management Circuits

This paper summarizes recent research at the author’s laboratory into power management circuitry, including: (1) Envelope-tracking power supplies for base station power amplifiers, (2) Digital PWM generator circuitry, (3) Spreadspectrum clocking for EMI reduction in digitally-controlled power supplies, (4) High-efficiency coupled-inductor DC-DC converters with fast response and low ripple, and ...
