Earthquake Moment Magnitudes from Peak Ground Displacements and Synthetic Green's Functions

Seismica
We suggest an approach employing full waveforms from synthetic seismograms to estimate moment magnitudes and their uncertainties from peak amplitudes. The new method is theoretically derived.

Determination of earthquake focal depths and source time functions in central Asia using teleseismic P waveforms [PDF]

, 2009
We developed a new method to determine earthquake source time functions and focal depths. It uses theoretical Green's function and a time-domain deconvolution with positivity constraint to estimate the source time function from the teleseismic P ...

Synthetic Electrocardiogram Spectrogram Generation Using Generative Adversarial Network‐Based Models: A Comparative Study

Advanced Intelligent Systems, EarlyView.
Cardiovascular diseases are leading death causes; electrocardiogram (ECG) analysis is slow, motivating machine learning and deep learning. This study compares deep convolutional generative adversarial network, conditional GAN, and Wasserstein GAN with gradient penalty (WGAN‐GP) for synthetic ECG spectrograms; Fréchet Inception Distance (FID) and ...

Coseismic Frictional Heating With Concomitant Hydrothermal Fluid Circulation Revealed by Rock Magnetic Properties of Fault Rocks From the Rupture of the 2008 Wenchuan Earthquake, China

Geochemistry, Geophysics, Geosystems, 2023
Coseismic frictional heating and associated hydrothermal fluid circulation play an essential role in the dynamic weakening of seismic faults. However, temperature rise induced by frictional heating during an earthquake is still difficult to constrain ...

Facilitators and barriers to neighborhood social integration

American Journal of Community Psychology, EarlyView.
Abstract Social isolation has reached concerning rates, particularly in the wake of the COVID‐19 pandemic. Social integration is critical to combatting social isolation and loneliness by promoting a sense of community and belonging. Yet, most existing research centers on fostering close personal relationships within family and friend networks.

Geodetic, teleseismic, and strong motion constraints on slip from recent southern Peru subduction zone earthquakes [PDF]

, 2007
We use seismic and geodetic data both jointly and separately to constrain coseismic slip from the 12 November 1996 M_w 7.7 and 23 June 2001 M_w 8.5 southern Peru subduction zone earthquakes, as well as two large aftershocks following the 2001 earthquake ...

The Phenotypic Spectrum of Sporadic Creutzfeldt‐Jakob Disease Cortical Subtype

Annals of Neurology, EarlyView.
Objective The objective of this study was to characterize the phenotypic spectrum of the rare sporadic Creutzfeldt‐Jakob disease cortical subtype (sCJDMM/MV2C) in a large multicentric autopsy cohort. Methods We evaluated clinical histories, biofluid markers, brain diffusion‐weighted (DW)‐magnetic resonance imaging (MRI), and electroencephalogram (EEG ...

Measuring Impulse-DSI and its Derivatives Via the Isometric Belt Squat: Assessing Relationships with Sprint Ability Among Division 1 Team Sport Athletes

International Journal of Strength and Conditioning
The dynamic strength index (DSI) is a common athlete profiling tool that has traditionally been derived as the ratio between the peak force in the isometric mid-thigh pull (IMTP) and the countermovement jump (CMJ) to identify ballistic strength deficits.

Rapid and quantitative uncertainty estimation of coseismic slip distribution for large interplate earthquakes using real-time GNSS data and its application to tsunami inundation prediction

Earth, Planets and Space, 2022
This study proposes a new method for the uncertainty estimation of coseismic slip distribution on the plate interface deduced from real-time global navigation satellite system (GNSS) data and explores its application for tsunami inundation prediction ...

Enhanced Sensitivity of a Modified Quaking‐Induced Conversion Diagnostic Test for the Broad Detection of Sporadic and Inherited Prion Diseases: A Retrospective Study

Annals of Neurology, EarlyView.
Objective Quaking‐induced conversion (QuIC) tests, which detect prion‐seeding activity in cerebrospinal fluid (CSF), have markedly advanced the antemortem diagnosis of prion diseases such as Creutzfeldt‐Jakob disease (CJD). These tests provide high diagnostic accuracy and enable timely differentiation from other rapidly progressive neurodegenerative ...
