Treatment planning evolution: Comparing approaches in photodynamic and radiation therapies

Photochemistry and Photobiology, Volume 101, Issue 5, Page 1100-1119, September/October 2025.
Oncological therapy based on radiation therapy (RT) is well‐developed, with widely accepted therapeutic dose concepts based on its mechanisms of action, which are applied to personalized treatment planning using sophisticated programs and tools.

Rising‐Tone Whistler Wave in a Magnetosheath Side Separatrix of Dayside Magnetic Reconnection

Geophysical Research Letters, Volume 52, Issue 16, 28 August 2025.
Abstract We investigate Magnetospheric Multiscale (MMS) observation of the rising‐tone whistler waves during the magnetopause asymmetric magnetic reconnection on 24 December 2016. The rising‐tone whistler wave propagates toward the electron diffusion region of magnetic reconnection along the magnetic field on the magnetosheath side of the separatrix ...

Surface Characterization of Scintillator‐Adsorbed Polyethylene Terephthalate Film and Its Use for Detecting α ‐ and β ‐Particles

Journal of Applied Polymer Science, Volume 142, Issue 29, August 5, 2025.
Thermal transfer using the high‐temperature crimping method led to the bonding of cellulose fibers and a scintillator to the film surface. β‐Particles of tritiated water were detected by immersing the scintillator‐adsorbed film. Scintillation images of the scintillator‐adsorbed film were obtained by irradiating β‐particles from 90Sr/90Y and α‐particles

Generation of incoherent Cherenkov diffraction radiation in synchrotrons

Physical Review Accelerators and Beams, 2020
Incoherent Cherenkov diffraction radiation was recently produced in the Cornell electron storage ring using counterpropagating beams (electrons and positrons) passing in the close vicinity of a dielectric made of fused silica.

Resonant Diffusive Radiation in Random Multilayered Systems

, 2005
We have theoretically shown that the yield of diffuse radiation generated by relativistic electrons passing random multilayered systems can be increased when a resonant condition is met.

All-fiber femtosecond Cherenkov source

EPJ Web of Conferences, 2013
An all-fiber femtosecond Cherenkov radiation source is demonstrated for the first time, to the best of our knowledge. Using a stable monolithic femtosecond Ybdoped fiber laser as the pump source, and the combination of photonic crystal fibers as the wave-

Commissioning and clinical implementation of low dose dual‐field rotational TSET

Journal of Applied Clinical Medical Physics, Volume 26, Issue 7, July 2025.
Abstract Background Total skin electron therapy (TSET) is a specialized technique for treating cutaneous T‐cell lymphomas, such as mycosis fungoides. While traditional TSET regimens prescribe 30–36 Gy, low dose TSET at 12 Gy has gained attention due to its reduced toxicity.

Characterizing diamond detectors for various dose and dose rate measurements in scanned carbon and oxygen beams

Medical Physics, Volume 52, Issue 7, July 2025.
Abstract Background The emerging FLASH radiotherapy technique employs “Ultra‐High Dose Rate” (UHDR) irradiations and offers the potential to spare normal tissue while maintaining iso‐effective tumor treatment. Given the physical and biological advantages inherent to high “Linear Energy Transfer” (LET) particles, the combination of UHDR and high LET has

Angular width of Cherenkov radiation with inclusion of multiple scattering: an path-integral approach

, 2016
Visible Cherenkov radiation can offers a method of the measurement of the velocity of a charged particles. The angular width of the radiation is important since it determines the resolution of the velocity measurement.
