Impact of respiratory motion on dose distribution in SIB‐SBRT for lung cancer

Journal of Applied Clinical Medical Physics, EarlyView.
Abstract Purpose Respiratory motion is a major source of dose uncertainty in lung cancer radiotherapy. The dose distribution of simultaneous integrated boost‐stereotactic body radiotherapy (SIB‐SBRT) is inhomogeneous and is significantly impacted by respiratory motion for lung cancer. The effect of respiratory motion on SIB‐SBRT was investigated with a

Spacetime Splitting, Admissible Coordinates and Causality

, 2012
To confront relativity theory with observation, it is necessary to split spacetime into its temporal and spatial components. The (1+3) timelike threading approach involves restrictions on the gravitational potentials $(g_{\mu \nu})$, while the (3+1 ...

Ageism in Rheumatology: the Healthcare Professional's Perspective

Arthritis Care &Research, Accepted Article.
Objective Ageism (age‐based stereotypes, prejudice, or discrimination) is prevalent and linked to prolonged disability and reduced lifespan in older adults. Little is known about ageism within rheumatology. This study explores the healthcare professional's (HCP) perception of the care of older adults and how ageist attitudes or perspectives may impact ...

Historical and Pedagogical Chronology of the Development of Ethno-confessional Musical Education of Mennonites in the South of Ukraine (End of the 18th - Early XX Centuries) [PDF]

, 2018
Historical and chronological principles that the development of musical education of Mennonites in the South of Ukraine (from the end of the 18th century to the beginning of the 20th century) is based on were explained.

Chronology Protection and Non-Naked Singularity

, 1998
We test the chronology protection conjecture in classical general relativity by investigating finitely vicious space-times. First we present singularity theorems in finitely vicious space-times by imposing some restrictions on the chronology violating ...

Retrotransposon Expression Is Upregulated in Adulthood and Suppressed during Regeneration of the Limb in the Axolotl (Ambystoma mexicanum)

Advanced Biology, EarlyView.
The axolotl's remarkable regenerative abilities decline with age, the causes may include the numerous repetitive elements within its genome. This study uncovers how Ty3 retrotransposons and coexpression networks involving muscle and immune pathways respond to aging and regeneration, suggesting that transposons respond to physiological shifts and may ...

More on the chronology of Celtic sound changes [PDF]

, 2010
Graham Isaac’s recent monograph (2007) deals with the chronology of Celtic sound changes. Remarkably, the author completely disregards the relative chronology which I published 28 years earlier (1979).

Constraining the Cratering Chronology of Vesta

, 2014
Vesta has a complex cratering history, with ancient terrains as well as recent large impacts that have led to regional resurfacing. Crater counts can help constrain the relative ages of different units on Vesta's surface, but converting those crater ...

Analysis of Temperature and Stress Distribution on the Bond Properties of Hybrid Tailored Formed Components

Advanced Engineering Materials, EarlyView.
Hybrid materials enable high‐performance components but are challenging to process. This study explores an inductive heating concept with spray cooling for steel–aluminum specimens in a two‐step process including friction welding and cup backward extrusion.

On the relative chronology of Slavic accentual developments [PDF]

, 2010
Last year Georg Holzer proposed a relative chronology of accentual developments in Slavic (2005). Here I shall compare his chronology with the one I put forward earlier (1975, 1989a, 2003) and discuss the differences. For the sake of convenience, I first
