We describe an analog VLSI implementation of a multi-dimensional gradient estimation and descent technique for minimizing an onchip scalar function fO. The implementation uses noise injection and multiplicative correlation to estimate derivatives, as in [Anderson, Kerns 92]. One intended application of this technique is setting circuit parameters on-chip automatically, rather than manually [Kir...

Patient readiness to adopt new beliefs and coping responses to pain may predict response to multidisciplinary or cognitive-behavioral pain treatments that emphasize changes in beliefs and coping behaviors. According to the transtheoretical model of change, individuals go through specific stages in the process of changing maladaptive behaviors. Based on this model, Kerns et al. (1997) (Kerns RD,...

The paper provides a new (pre)kernel catcher in that the relevant set always contains the (pre)kernel. This new (pre)kernel catcher gives rise to a better lower bound 5.** such that the kernel is included in strong e-cores for all real numbers 5 not smaller than the relevant bound 5***. Zusammenfassung. Es wird eine/iul3ere Approximation des (Pr/i-)Kerns vorgestellt. Diese liefert eine bessere ...

Aromatische Seitenketten sind wichtige Indikatoren für die Plastizität von Proteinen und bilden oft entscheidende Kontakte bei Protein-Protein-Wechselwirkungen. Wir untersuchten aromatische Reste in den beiden strukturell homologen cross-β Amyloidfibrillen HET-s HELLF mit Hilfe eines spezifischen Ansatzes zur Isotopenmarkierung Festkörper NMR Drehung am magischen Winkel. Das dynamische Verhalte...
