Clinically Relevant Motion of Canine Thoracic Tumors Is Seen Between Inspiratory and Expiratory Breath Holds on Computed Tomography Performed for Radiation Treatment Planning

Veterinary Radiology &Ultrasound, Volume 67, Issue 4, July 2026.
ABSTRACT Advancements in radiation therapy allow for targeting smaller tumor volumes with exceedingly conformal precision. Target motion during the breathing cycle needs to be anticipated. To date, no information exists that characterizes the motion of canine thoracic tumors during the respiratory cycle.

Short‐Wavelength Infrared Imaging with Organic Photodetectors Based on Non‐Fullerene Acceptors with Detection above 1200 nm

Advanced Materials, Volume 38, Issue 31, 2 June 2026.
Solution‐processed organic photodetectors (OPDs) based on two novel low band gap non‐fullerene acceptors BZIC‐2F and BZIC‐2Cl, when blended with common polymer donor P3HT, extend detection range beyond 1200 nm with superior performance, rivaling costly inorganic sensors and past literature.

The Constraint of Crewed Mars Missions Based on Current Radiation Dose Measurements

Space Weather
Crewed missions to Mars will be a milestone of future space exploration programs. However, the absence of Earth's magnetic field leaves astronauts directly exposed to unattenuated energetic particles in deep space, primarily galactic cosmic rays (GCRs ...

Long‐Term Variation of the Galactic Cosmic Ray Radiation Dose Rates

Space Weather
In this work, a model for calculating the galactic cosmic rays (GCRs) radiation dose rate is developed. The model is based on a GCR modulation model, which is established by Shen and Qin, and the fluence‐dose conversion coefficients (FDCCs) published by ...

Toward Explaining Galactic Cosmic-Ray Modulation in a Dynamic Heliosheath: Transient Structures Seem Dominant and Magnetic Drifts Appear Reduced

The Astrophysical Journal
While traveling through the heliosheath (HS), Voyager 2 observed sustained flux depletions of galactic cosmic rays (GCRs) on scales of months to years.

Forecasting of the Time-dependent Fluxes of Antiprotons in the AMS-02 Era

The Astrophysical Journal
The spectra of Galactic cosmic rays (GCRs) contain crucial information about their origin and propagation through the interstellar medium. When GCRs reach Earth, they are significantly influenced by the solar wind and the heliospheric magnetic field, a ...

Solar Modulation of AMS-02 Daily Proton and Helium Fluxes with Modified Force-field Approximation Models

The Astrophysical Journal
As galactic cosmic rays (GCRs) propagate through the turbulent plasma environment within the heliosphere, they undergo a process of diffusion, drift, and energy loss, leading to a notable reduction in their flux.
