Spatiotemporally localized optical links and knots

Nature Communications
Optical links and knots have attracted growing attention owing to their exotic topologic features and promising applications in next-generation information transfer and storage. However, current protocols for optical topology realization rely on paraxial

Precision separation of thick double-sided microlens arrays via stepwise immersion ultrafast laser modification and controlled thermal stress

Materials & Design
Double-sided microlens arrays (DSMLAs) are integral to large field of view imaging and precise beam shaping in compact optical systems. However, separating thick DSMLAs with precision and efficiency remains challenging, particularly due to laser ...

Comparing the paths of Hedgehog release in artificial and natural settings

FEBS Letters, EarlyView.
Hh morphogens require solubilization factors to overcome their tight association with the plasma membrane and signal to distant cells, but the precise functions of these factors are controversial. Here, we use published in vivo observations as the most relevant evidence to test their suggested functions and discuss contradictions and gaps between in ...

A Phenomenological Model for Dynamic Expansion of Defects in Semiconductor Lasers

Crystals
The failures of semiconductor lasers are often linked to the emergence or growth of defects. However, most research mainly focuses on the postmortem failure analysis caused by defects, lacking dynamic process analysis of defect expansion. This limitation

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment

Molecular Oncology, EarlyView.
This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

An Investigation into the Planning of Cutting Interpolation Point Positions to Improve the Surface Quality of Satellite Laser Communication Reflectors

Micromachines
Spherical/aspherical mirrors are widely used in satellite communication and imaging systems, but their reflectivity is affected by the surface roughness value.

Stimulator of interferon genes agonist augmented antitumor immunity of osimertinib in Egfr‐mutated lung cancer

Molecular Oncology, EarlyView.
Combining osimertinib with the STING agonist ADU‐S100 activates innate and adaptive immunity to overcome the non‐inflamed microenvironment of Egfr‐mutant lung cancer. This combination increases NK and CD8+ T‐cell infiltration, associated with activation of the STING‐IRF3 pathway and local immunogenic cell death.

Light Field Inpainting Propagation via Low Rank Matrix Completion [PDF]

, 2018
International audienceBuilding up on the advances in low rank matrix completion, this article presents a novel method for propagating the inpainting of the central view of a light field to all the other views. After generating a set of warped versions of
