Heterogeneous Myocardial Adaptation to Pressure Overload Reveals a Spared, Vulnerable Segment Identified by Multiparametric Cardiac MRI

open access: yesNMR in Biomedicine, Volume 39, Issue 5, May 2026.
Graphical summary of a longitudinal multiparametric MRI study in mouse TAC model, showing imaging at baseline, 3 days, 4 weeks and 7 weeks. All TAC animals developed global LV hypertrophy (+62% LV mass at week 7), but half displayed a spared‐hypertrophy basolateral region.

Micro-Doppler Based Human-Robot Classification Using Ensemble and Deep Learning Approaches

open access: yes, 2018
Radar sensors can be used for analyzing the induced frequency shifts due to micro-motions in both range and velocity dimensions identified as micro-Doppler ($\boldsymbol{\mu}$-D) and micro-Range ($\boldsymbol{\mu}$-R), respectively.

Hyaluronic Acid Dermal Filler‐Associated Vascular Occlusion—A Review of Prevention and Management Strategies

open access: yesJournal of Cosmetic Dermatology, Volume 25, Issue 5, May 2026.
ABSTRACT Background Significant complications are uncommon with aesthetic hyaluronic acid (HA) dermal fillers, but inadvertent injection of dermal filler into an artery can result in tissue damage, scarring, visual loss, and even stroke. Practitioners must therefore reduce this risk through proactive, preventative techniques.

Theoretical study of dark resonances in micro-metric thin cells

open access: yes, 2007
We investigate theoretically dark resonance spectroscopy for a dilute atomic vapor confined in a thin (micro-metric) cell. We identify the physical parameters characterizing the spectra and study their influence.

From Cure to Complexity: Post‐SVR Liver and Metabolic Trajectories in Diabetic Patients

open access: yesLiver International, Volume 46, Issue 5, May 2026.
ABSTRACT Background and Aims The long‐term impact of HCV cure on hepatic and metabolic outcomes in patients with type 2 diabetes (T2D) remains insufficiently defined. This study evaluated T2D‐related vascular complications, liver disease progression and overall survival over 9 years of follow‐up, also exploring genetic variability contribution ...

Human Anomalous Gait Termination Recognition via Through-the-wall Radar Based on Micro-Doppler Corner Features and Non-Local Mechanism

open access: yesLeida xuebao
Through-the-wall radar can penetrate walls and realize indoor human target detection. Deep learning is commonly used to extract the micro-Doppler signature of a target, which can be used to effectively identify human activities behind obstacles. However,
