DOI: 10.1007/s12194-019-00539-1
Abstract: Intensity-modulated radiation therapy has recently been used for total scalp irradiation. In inverse planning, the treatment planning system increases the fluence of tangential beam near the skin surface to counter the build-up region. Consequently, the… read more here.

DOI: 10.1016/j.ejmp.2018.06.477
Abstract: Purpose Most of the breast treatments uses a megavoltage photon beams. This kind of energy exhibits a skin-sparing effect that is a concern in some stages of both breast conservative and post-mastectomy irradiation. To overwhelm… read more here.

DOI: 10.1017/jfm.2019.993
Abstract: Internal waves shoaling on the continental slope can break and form materially coherent vortices called boluses. These boluses are able to trap and transport material up the continental slope, yet the global extent of bolus… read more here.

DOI: 10.1038/s41598-019-52269-4
Abstract: Thickened fluids are commonly used in the medical management of individuals who suffer swallowing difficulty (known as dysphagia). Previous studies have shown that the rheological properties of a liquid affect the flow behavior of the… read more here.
