Voting Red Again: How Social Capital and Local Change Drove the Trump Swing

open access: yesJournal of Regional Science, EarlyView.
ABSTRACT Social capital has long been regarded as a bulwark of democratic life. Yet in the United States—as across much of the democratic world—some of the communities with the densest social ties have proved the most receptive to antisystem politics.

Insights into the Aftershocks and Inter-Seismicity for Some Large Persian Earthquakes [PDF]

open access: yesJournal of Sciences, Islamic Republic of Iran, 2015
This paper focuses on aftershocks behavior and seismicity along some co-seismic faults for large earthquakes in Iran. The data of aftershocks and seismicity roughly extracted from both the Institute of Geophysics the University of Tehran (IGUT) and ...

SEISMIC FRAGILITY EVALUATION OF SOIL-PILE-STRUCTURE INTERACTION EFFECTS SUBJECTED TO MAINSHOCK-AFTERSHOCK RECORDS

open access: yesInternational Journal for Computational Civil and Structural Engineering, 2023
In most current seismic design on bridges, only mainshock actions are considered without incorporating the effect of mainshock-aftershock (MA) sequences and interaction soil-pile.However, a large mainshock usually triggers numerous aftershocks in a ...

Polymict melt‐bearing breccia dikes in the Morokweng impact structure formed by slip‐induced mechanical mixing of pseudotachylite and cataclasite along large‐displacement impact faults

open access: yesMeteoritics &Planetary Science, EarlyView.
Abstract A core drilled through shocked and faulted Archean granitoid gneisses and dolerites in the eroded peak ring of the 70–80 km diameter Morokweng impact structure intersects multiple centimeter‐ to meter‐wide clastic‐matrix breccias containing a polymict clast population of lithic and mineral clasts and altered, millimeter‐ to centimeter ‐size ...

Analysis of the Wenchuan aftershock data [PDF]

open access: yes, 2012
We analyse the aftershocks of theWenchuan earthquake in 2008 using a multivariate non-normal distribution fitted to the observations for the variables selected from the inter-aftershock times, depths, magnitudes, sines and cosines of the azimuths, slant

Spaceborne and spaceborn: Physiological aspects of pregnancy and birth during interplanetary flight

open access: yesExperimental Physiology, EarlyView.
Abstract Crewed interplanetary return missions that are on the planning horizon will take years, more than enough time for initiation and completion of a pregnancy. Pregnancy is viewed as a sequence of processes – fertilization, blastocyst formation, implantation, gastrulation, placentation, organogenesis, gross morphogenesis, birth and neonatal ...

Aftershock Accelerograms Recorded on a Temporary Array [PDF]

open access: yes, 1982
We recovered 52 timed analog accelerograms from 25 aftershocks of the 1979 Imperial Valley earthquake, between 3:33p.m. P.d.t. October 16 and 5:43 a.m. October 31. The largest aftershock that we recorded (M_L =4.9) occurred at 4:16p.m.

Estimating Secondary Earthquake Aftershocks from Tsunamis

open access: yesGeosciences
Nonlinear solitary waves influence the Earth’s crust because wave pressure on the ocean bottom contains non-hydrostatic components. Our physical-mathematical model allows us to calculate the surplus super-hydrostatic pressure on the Earth’s crust.
