A crack-like notch analogue for a safe-life fretting fatigue design methodology [PDF]
, 2003 Various analogies have recently been proposed for comparing the stress fields induced in fretting fatigue contact situations, with those of a crack and a sharp or a rounded notch, resulting in a degree of uncertainty over which model is most appropriate ...

Active control of vibrant actuators with adaptive adjustment of the reference [PDF]
, 1999 An improved adaptive filter for eliminating periodic vibrations of unknown frequency in rotary machinery is presented. The proposed canceller is based on a usual bank of digital adaptive notch filters, each filter tuned in the cancellation of one ...

Resolving Astrocyte Heterogeneity in the CNS
Frontiers in Cellular Neuroscience, 2017 Astrocytes play essential roles in nearly all aspects of brain function from modulating synapses and neurovasculature to preserving appropriate extracellular solute concentrations. To meet the complex needs of the central nervous system (CNS), astrocytes

Notch signaling and Notch signaling modifiers [PDF]
The International Journal of Biochemistry & Cell Biology, 2011 Originally discovered nearly a century ago, the Notch signaling pathway is critical for virtually all developmental programs and modulates an astounding variety of pathogenic processes. The DSL (Delta, Serrate, LAG-2 family) proteins have long been considered canonical activators of the core Notch pathway. More recently, a wide and expanding network of

Suppression of Second-Order Harmonic Current for Droop-Controlled Distributed Energy Resource Converters in DC Microgrids [PDF]
, 2020 Droop-controlled distributed energy resource converters in dc microgrids usually show low output impedances. When coupled with ac systems, second-order harmonics typically appear on the dc-bus voltage, causing significant harmonic currents at the ...

Notch one for activating NOTCH [PDF]
Science-Business eXchange, 2011 Vanderbilt researchers have identified downregulation of NOTCH signaling as a mechanism tumors use to evade the immune system, suggesting that restoring activation of the pathway could improve cancer immunotherapy. Researchers have been split on whether it is better to up- or downregulate NOTCH.
