GPX4 Inhibitor Resistance and Metastatic Features in Triple‐Negative Breast Cancer

Advanced Science, Volume 13, Issue 23, 23 April 2026.
This study establishes breast cancer cell lines that are resistant to glutathione peroxidase 4 inhibitors (GPX4i) in vitro and investigates the metastatic capacity of the GPX4i‐resistant versus parental lines in vivo. GPX4i‐resistant cells survive upon intravenous injection, but lose capacity to spontaneously metastasize.

Pearcey plasmon: An autofocusing surface wave

Results in Physics, 2021
In this article, we present a new kind of autofocusing surface plasmonic wave: the Pearcey plasmon. The result shows that the Pearcey plasmon evolves at the silver-air interface in the form of two-dimensional Pearcey plasmon function.

Focusing property of autofocusing Bessel beams

Optics Express, 2023
We introduce what we believe to be a new family of abruptly autofocusing waves named autofocusing Bessel beams (ABBs). Since the beams only strongly influence the area near the focus, it holds promise for medical laser treatment and optical tweezers. By the angular spectrum method, ABBs are proved to be a class solution for the Helmholtz equation.

Metabolic Alterations in Macrophage Subtypes Propel Immune and Stromal Remodeling in Neurofibroma's Malignant Progression

MedComm, Volume 7, Issue 4, April 2026.
Illustration of the microenvironment factors driving malignant progression in MPNSTs. ABSTRACT Neurofibromatosis type 1 (NF1) is characterized by the development of benign plexiform neurofibromas (PNFs). In 10%–15% of patients, these tumors undergo malignant transformation into aggressive malignant peripheral nerve sheath tumors (MPNSTs).

Micro Biomimetic Eyeball for Humanoid Robots: A Visual System with High‐Density Functional Integration Based on an Origami Mechanism

Advanced Science, Volume 13, Issue 1, 5 January 2026.
A biomimetic eyeball system (BES) based on a 3‐DOF miniature origami mechanism, which addresses the inherent issues of large size and weight in traditional electromechanical BESs is presented. Moreover, it maintains a level of visual functionality comparable to that of the human eye, including capabilities such as rapid scanning, target recognition ...

Multistatic Frequency and Polarimetry Adaptive Autofocus for Synthetic Aperture Radar Imaging of a Moving Target

IET Radar, Sonar &Navigation, Volume 20, Issue 1, January/December 2026.
This paper presents a multistatic, frequency‐ and polarimetry‐adaptive autofocus algorithm (F‐Pol) for SAR imaging of moving targets undergoing complex, six‐degrees‐of‐freedom (6‐DoF) motion. Building on Localised Threshold Sharpness (LTS), the method exploits agreement across frequency sub‐bands and polarisation channels to improve pulse‐by‐pulse ...

Dynamic Control of Circular Airy Beams With Linear Optical Potentials

IEEE Photonics Journal, 2012
We investigate the propagation dynamics of radially symmetric, circular Airy beams through a medium having linear optical potentials. On the basis of analytic expressions and numerical calculations, we show that “off-axis” autofocusing can ...
