Anisotropy and Energy Evolution Characteristics of Shales: A Case Study of the Longmaxi Formation in Southern Sichuan Basin, China

open access: yesGeofluids
To obtain the influence of anisotropy and energy evolution characteristics on wellbore stability, the acoustic and mechanical anisotropy characteristics of shales are studied through various experiments, including scanning electron microscopy, ultrasonic

Multiphase Tectonic Process With Slab Dynamics in the Northern East China Sea Shelf Basin

open access: yesGeological Journal, EarlyView.
Megasequence 1 characterised by Palaeocene extension and differential subsidence driven by the rollback of the subducting Izanagi Plate. Megasequence 2 records a kinematic reorganisation of the East Asian margin, transition from a rifting to a compressional regime.

Longitudinal splitting in unidirectional composites, analysis and experiments [PDF]

open access: yes
An experimental study is conducted to determine the fracture behavior of center notched, unidirectional graphite/epoxy laminates when subjected to tensile loading. The actual behavior is compared to the behavior predicted by a mathematical model based on

Embedded AI‐Enabled Wearable Piezoelectric Sensing Cluster for Real‐Time Multijoint Motion Recognition

open access: yesInterdisciplinary Materials, EarlyView.
The distributed multijoint motion recognition cluster based on polyvinylidene fluoride membranes with high piezoelectric properties adopted a one‐master‐multiple‐slaves architecture and multipoint wireless collaboration to synchronously recognize motions of the wrist, elbow, and shoulder.

Early deglaciation history of the southeastern Baffin Island shelf (Eastern Canadian Arctic Archipelago)

open access: yesJournal of Quaternary Science, EarlyView.
ABSTRACT During the last glacial period, the Laurentide Ice Sheet (LIS) was the largest terrestrial ice sheet on Earth. Its evolution since the Last Glacial Maximum profoundly influenced Earth's geodynamics and surface processes. Investigating the past dynamics of the LIS provides critical insights into how contemporary ice sheets may respond to ...

Progress in mantle anisotropy research based on XKS phases

open access: yes地球与行星物理论评
XKS shear-wave splitting has been widely applied to investigations of anisotropy in both the upper mantle and the lowermost mantle D" layer, and represents a key tool for probing mantle deformation and dynamics.

Reidite Formation From Zircon Subjected to 20, 40, and 60 GPa Shock Experiments

open access: yesJournal of Raman Spectroscopy, EarlyView.
Structure disordering as a result of shock pressure: In zircon shocked from 20 to 60 GPa, the shock‐induced structural disorder increases with increasing shock pressure (gray area). Shock disorder of zircon is an integral part of its transformation to reidite: Reidite occurs after amorphous material.

Shear Wave Elastography for Characterization of Breast Lesions in Clinical Routine

open access: yesJournal of Ultrasound in Medicine, EarlyView.
Objectives Breast cancer remains a major global health challenge, and conventional B‐mode ultrasound frequently encounters limitations in reliably distinguishing benign from malignant lesions, particularly within intermediate Breast Imaging‐Reporting and Data System (BI‐RADS) categories.

Exploration of a Multimodal Machine Learning Model Integrating Ultrasound and Clinical Indicators for the Diagnosis of Diabetic Peripheral Neuropathy

open access: yesJournal of Ultrasound in Medicine, EarlyView.
Objectives Based on ultrasound technology and clinical indicators, this study intends to develop multiple risk prediction models for diabetic peripheral neuropathy (DPN), conduct comparative analyses of these models, and further evaluate and validate the diagnostic efficacy of the optimal model for DPN as well as its potential in clinical application ...

Quantifying Dehydration Effects of Porcine Vocal Fold Attenuation With Optical Coherence Tomography

open access: yesThe Laryngoscope, EarlyView.
The purpose of this study is to use optical coherence tomography (OCT) to characterize the effect of dehydration on the optical attenuation coefficient of porcine vocal fold (VF) tissue. The optical attenuation coefficient tissue decreased linearly with dehydration, dropping by approximately 0.08 mm−1 for every 1% increase in mass loss.
