Tidal evolution of the eccentric moon around dwarf planet (225088) Gonggong [PDF]
, 2021 Recent astronomical observations revealed that (225088) Gonggong, a 1000-km-sized trans-Neptunian dwarf planet, hosts an eccentric satellite, Xiangliu, with an eccentricity of approximately 0.3. As the majority of known satellite systems around trans-Neptunian dwarf planets have circular orbits, the observed eccentricity of Gonggong--Xiangliu system ...

Dosimetric uncertainties related to the elasticity of bladder and rectal walls: Adenocarcinoma of the prostate [PDF]
cancer radioth\'erapie 15, 3 (2011) 168-240, 2011 Purpose. - Radiotherapy is an important treatment for prostate cancer.During treatment sessions, bladder and rectal repletion is difficult to quantify and cannot be measured with a single and initial CT scan acquisition. Some methods, such as image-guided radiation therapy and dose-guided radiation therapy, aimto compensate thismissing information ...

Fully Automated Organ Segmentation in Male Pelvic CT Images [PDF]
Balagopal A, Kazemifar S, Nguyen D, Lin M H, Hannan R, Owrangi A
and Jiang S 2018 Fully automated organ segmentation in male pelvic CT images
Phys. Med. Biol. 63 245015, 2018 Accurate segmentation of prostate and surrounding organs at risk is important for prostate cancer radiotherapy treatment planning. We present a fully automated workflow for male pelvic CT image segmentation using deep learning. The architecture consists of a 2D localization network followed by a 3D segmentation network for volumetric segmentation of ...
