Density override‐based VMAT optimization to improve robustness at tissue‐air interfaces in head and neck radiotherapy

Journal of Applied Clinical Medical Physics, Volume 27, Issue 9, September 2026.
Abstract Background Volumetric Modulated Arc Therapy (VMAT) is integral to head and neck (HN) radiation therapy; however, plan robustness may be compromised at air‐tissue interfaces. Highly modulated fluence directed at these areas can produce significant unexpected high‐dose regions in the event of minor variations in tissue density.

A rule‐based, feedback‐driven framework for fully automated prostate VMAT planning

Journal of Applied Clinical Medical Physics, Volume 27, Issue 9, September 2026.
Abstract Background Manual prostate volumetric modulated arc therapy (VMAT) planning in Elekta Monaco is complex, time‐intensive, and prone to planner variability. Existing automation methods, such as knowledge‐based planning (KBP) and cloud‐based solutions often rely on external models rather than Monaco's native optimization.

Detection of Dark Companions via The Combination of Eclipse Timing Variation, Hipparcos, and/or Gaia Astrometry: The Cases of V Puppis and CY Ari

The Astrophysical Journal
The third body is expected to shape the formation and evolution of close binary systems. In this work, we develop a method to detect and characterize the tertiary companion around eclipsing binaries through the combined analysis of eclipse timing ...

Interaction‐Driven Assembly Pathways in Heterogeneous Active Microrobotic Systems

Advanced Functional Materials, Volume 36, Issue 73, 10 September 2026.
Peanut‐ and cube‐shaped light‐powered microrobots exhibit distinct magnetic and photocatalytic responses that determine their heterogeneous self‐assembly. In the dark, magnetic dipole interactions drive colloidal copolymerization with cubes acting as nucleation centers, whereas under light irradiation, phoretic interactions compete with magnetic ...

Half a Million Binary Stars Identified from the Low-resolution Spectra of LAMOST

The Astrophysical Journal Supplement Series
Binary stars are prevalent yet challenging to detect. We present a novel approach using convolutional neural networks (CNNs) to identify binary stars from low-resolution spectra obtained by the LAMOST survey.

Unveiling α‐MoO3 as a High‐Index, Low‐Loss Anisotropic Material: Bridging the Gap From Mid‐Infrared to Ultraviolet Nanophotonics

Advanced Materials, Volume 38, Issue 49, 1 September 2026.
α‐MoO3 is established as a high‐index, low‐loss anisotropic platform bridging mid‐infrared polaritonics and ultraviolet‐visible nanophotonics. Spectroscopic ellipsometry and calculations reveal refractive indices exceeding 3.9, with the largest in‐plane birefringence among transparent layered crystals at 425–500 nm, enabling zero‐order UV waveplates ...

Nonsterile Cultivation of the Thermophilic Cyanobacterium Parathermosynechococcus lividus PCC 6715 in a Floating Light Ball Reactor (FLBR) on 53‐L Scale for Zeaxanthin Production

ChemFoodChem, Volume 2, Issue 3, September 2026.
We demonstrate cultivation of the thermophilic cyanobacterium Parathermosynechococcus lividus PCC 6715 at 40–55°C and 4 × 53 L scale using a Floating Light Ball Reactor (FLBR). The system enabled continuous illumination, non‐sterile operation with low contamination, flexible handling, and zeaxanthin production of 1.4–2.0 mg g−1, supporting future ...
