Absolute FKBP binding affinities obtained via non-equilibrium unbinding simulations
We compute absolute binding affinities for two ligands bound to the FKBP
protein using non-equilibrium unbinding simulations. The methodology is
straight-forward, requiring little or no modification to many modern molecular
simulation packages. The approach makes use of a physical pathway, eliminating
the need for complicated alchemical decoupling schemes. Results of this study
are promising. For the ligands studied here the binding affinities are
typically estimated within less than 4.0 kJ/mol of the target values; and the
target values are within less than 1.0 kJ/mol of experiment. These results
suggest that non-equilibrium simulation could provide a simple and robust means
to estimate protein-ligand binding affinities.Comment: 9 pages, 3 figures (no necessary color). Changes made to methodology

Electrostatically-Driven Resonator on Soi with Improved Temperature Stability
This paper deals with a single-crystal-silicon (SCS) MEMS resonator with
improved temperature stability. While simulations have shown that the
temperature coefficient of resonant frequency can be down to 1 ppm/degrees C,
preliminary measurements on non-optimised structures gave evidence of a
temperature coefficient of 29 ppm/degrees C. Design, optimisation, experimental
results with post process simulation and prospective work are presented.Comment: Submitted on behalf of TIMA Editions

Weiterbildungsprogramm in Hausarztmedizin Ein Gegenvorschlag zum Weiterbildungsprogramm «AllgemeineInnereMedizin»
Für die hausärztliche Tätigkeit in der ambulanten Pri-märversorgung ist der Entwurf des Weiterbildungsprogramms(WBP)«AllgemeineInnereMedizin»(AIM)weit weg von internationalen Standards und verbaut mit der Übergewichtung der stationären Inneren Medizin die weitere Entwicklung der Hausarztmedizin in der Schweiz. In diesem Artikel wird der Rahmen eines WBP in Hausarztmedizin präsentiert, das im Pflichtteil alle WB-Bereiche der Hausarztmedizin abdeckt, individuell grosse Freiheit lässt und auch zum Facharzt-Titel«All-gemeine Innere Medizin / Spitalinternist» offen ist
