Structured X-Ray Optics for Laboratory-Based Materials Analysis
, 2017 Metamaterials provide a challenge for materials analysis, as large-scale 3D geometries confound traditional methods. X-ray optics that allow for novel beam geometries and for more efficient use of conventional X-ray sources can be important in defect and

Molecular Oncology, EarlyView.Overexpression of CHRDL2 in colon cancer cells makes them more stem‐like and resistant to chemo‐ and radiotherapy. CHRDL2‐high cells have upregulation of the WNT pathway, genes involved in the DNA damage response (DDR) pathway and epithelial‐to‐mesenchymal transition (EMT). This leads to quicker repair of damaged DNA and more cell migration.

FEBS Open Bio, EarlyView.Long non‐coding RNAs (lncRNAs) occupy an abundant fraction of the eukaryotic transcriptome and an emerging area in cancer research. Regulation by lncRNAs is based on their subcellular localization in HNSCC. This cartoon shows the various functions of lncRNAs in HNSCC discussed in this review.

Log file‐based quality assurance method for respiratory gating system
Journal of Applied Clinical Medical Physics, EarlyView.Abstract Background As medical linear accelerator technology advances, enabling higher dose rate deliveries, hypofractionation regimens has increased. This necessitates respiratory gating systems that synchronize radiation delivery with tumor position, requiring simple rigorous quality assurance (QA) to ensure treatment accuracy and patient safety ...

Applied Optics, 1981 The European X-ray Observatory, EXOSAT, to be launched in 1981 will carry two Wolter I x-ray telescopes, each having a geometric area of ~100 cm(2). A qualification model of the Wolter I optics has been manufactured and extensively tested in optical and x-ray beams. The influence of manufacturing tolerances on the resolution of the optics is discussed,

Creation and annihilation of topological meron pairs in in-plane magnetized films
Nature Communications, 2019 A meron is one half of a skyrmion but whether a single meron pair can be created and stabilized remains a challenging question. Here, Gao et al. develop a method to create and stabilize individual pairs of merons in a continuous Py film by local vortex ...
