Healing Beams: Radiation and Radiotherapy in Novels, Poems, Music, Film, Painting

Journal of Medical Radiation Sciences, EarlyView.
Radiation and radiotherapy are perceived by patients and the general public as mysterious, dangerous and healing. The image of radiation and radiotherapy can be analysed by studying novels, poems, music, film and painting. Our paper reviews how radiation and radiotherapy are perceived by patients, the general public, as reflected in various art genres.

Last‐minute coordination: Adapting to demand to support last‐mile operations

Journal of Operations Management, Volume 71, Issue 2, Page 176-194, March 2025.
Abstract In the highly competitive e‐commerce industry, customer‐facing warehouses are crucial as the “order penetration points” for e‐commerce last‐mile operations. This research examines how warehouses use last‐minute coordination, an unstructured mechanism, to ensure sufficient inventory at the order penetration points. Previous research has focused

On Characteristics of Ship Noise

Journal of Zosen Kiokai, 1965
The airborne and solidborne noise measuring equipment, small in size and light in weight was especialily devised for ship, and various tests have been made for practical use.Using this equipment, noise and vibration measurement were made by several types of ship on their trial navigations. The results of observation about the noise source, spectrum and

Combining multibeam and single beam echosounders for quantifying gas bubble release from the seafloor

Limnology and Oceanography: Methods, EarlyView.
Abstract Marine gas bubble release is a worldwide phenomenon that impacts the local marine ecosystem and contributes to carbon fluxes with respect to global warming. It is still challenging to assess gas flow for large seep areas (tens of km2), but recent advances in calibrating and processing multibeam echosounder (MBES) data make this problem ...
