Local distribution of strong earthquake ground motions [PDF]
, 1972 Twenty ground stations distributed over a 40-square-mile area in Pasadena recorded strong ground shaking during the San Fernando earthquake of February 9, 1971. Relative responses at 10 of these same stations as measured for small earthquakes by standard

Modeling and identification in structural dynamics [PDF]
, 1987 Analytical modeling of structures subjected to ground motions is an important aspect of fully dynamic earthquake-resistant design. In general, linear models are only sufficient to represent structural responses resulting from earthquake motions of small ...

Protein pyrophosphorylation by inositol pyrophosphates — detection, function, and regulation
FEBS Letters, EarlyView.Protein pyrophosphorylation is an unusual signaling mechanism that was discovered two decades ago. It can be driven by inositol pyrophosphate messengers and influences various cellular processes. Herein, we summarize the research progress and challenges of this field, covering pathways found to be regulated by this posttranslational modification as ...

Rotational Motions Recorded at Hualien During the 2012 Wutai, Taiwan Earthquake
Terrestrial, Atmospheric and Oceanic Sciences, 2013 It is widely accepted that the effects of rotational motions on seismic waves can be neglected when ground motion is small and might be underestimated in near-fault and/or with extremely large ground motions.

Peak ground accelerations from large (M≥7.2) shallow crustal earthquakes : a comparison with predictions from eight recent ground-motion models [PDF]
, 2017 Strong-motion data from large (M≥7.2) shallow crustal earthquakes invariably make up a small proportion of the records used to develop empirical ground motion prediction equations (GMPEs).

AAA+ protein unfoldases—the Moirai of the proteome
FEBS Letters, EarlyView.AAA+ unfoldases are essential molecular motors that power protein degradation and disaggregation. This review integrates recent cryo‐electron microscopy (cryo‐EM) structures and single‐molecule biophysical data to reconcile competing models of substrate translocation.

pH‐mediated activation of the lysosomal arginine sensor SLC38A9
FEBS Letters, EarlyView.Cells monitor nutrient levels via the lysosomal transporter SLC38A9 to activate the mechanistic target of rapamycin complex 1 (mTORC1). This study reveals that SLC38A9 function is regulated by pH. We identified histidine 544 as a critical pH sensor that undergoes conformational changes to control amino acid efflux from lysosomes; therefore, it ...

Local and global effects of forward directivity
Građevinar, 2013 Previous studies have revealed that near-fault ground motions perpendicular to the fault slip are very destructive for structures. Due to the common use of moment resisting frames and the importance of near-fault strong motions, the local and global ...
