Pancake Lenses through Curved Lamination for Compact Virtual Reality

open access: yesAdvanced Intelligent Systems, EarlyView.
This article presents an ultrathin VR optical system based on a 1.35 in. microdisplay, leveraging curved lamination technology. Compared to mainstream solutions, the proposed design demonstrates superior compactness (volume compression by 12%) and enhanced optical performance.

Real‐Time, Label‐Free Classification of Cell Death Pathways via Holotomography‐Based Deep Learning Framework

open access: yesAdvanced Intelligent Systems, EarlyView.
A 3D holotomography system coupled with a deep learning model distinguishes how cells die—apoptosis, necroptosis or necrosis—without any fluorescent labels. Training on refractive index maps of HeLa cells yields 97% accuracy and flags necroptosis hours before chemical dyes.

A Multi‐instrument Recognition and Autonomous Tracking Control Method for Robot‐Assisted Endoscopic Adjustment

open access: yesAdvanced Intelligent Systems, EarlyView.
During lengthy minimally invasive surgeries, fatigue can cause surgeon tremor and poor endoscopic coordination. This study proposes a robot‐assisted endoscopic adjustment system. It employs a lightweight instrument detection model and a hierarchical multiconstraint controller for visual servoing.

Isovolumic relaxation strain imaging is an accurate and sensitive approach for detection of active diastolic dysfunction: A preclinical study

open access: yesAnimal Models and Experimental Medicine, EarlyView.
A modified approach was developed to accurately identify the isovolumetric relaxation time (IVRT) using an apical three‐chamber view. Compared with conventional echocardiography, isovolumic relaxation strain imaging (IVSI) helps to detect the earlier alternations of diastolic function in transverse aortic constriction (TAC) mice.

Methylophiopogonanone a attenuates pulmonary fibrosis by inhibiting SPP1‐mediated macrophage polarization via the PI3K/Akt pathway

open access: yesAnimal Models and Experimental Medicine, EarlyView.
Transcriptome sequencing identified secreted phosphoprotein 1 (SPP1) as a crucial target through which methylophiopogonanone A (MOA) ameliorates pulmonary fibrosis. Molecular docking and microscale thermophoresis (MST) assays confirmed a favorable binding affinity between MOA and SPP1.
