Dosimetric study of Rapid Arc therapy during Craniospinal Irradiation in Adult patients

open access: yesJournal of Radiation and Cancer Research, 2022
Context: Adult medulloblastomas are very rare and constitute only 1% of the central nervous system tumors in adults. CSI treatment is challenging in adults due to the long, irregular target volume, critical structures, and field matchings due to multiple

Outcomes of Modified Tissue Selection Therapy Stapler in the Treatment of Prolapsing Hemorrhoids

open access: yesFrontiers in Surgery, 2022
ObjectiveTissue selection therapy staplers (TSTs) are widely used to treat prolapsing hemorrhoids; however, some disadvantages exist. We describe a modified technique for the treatment of prolapsing hemorrhoids, with the aim of minimizing the risk of ...

Colloids in two-dimensional active nematics: conformal cogs and controllable spontaneous rotation

open access: yesNew Journal of Physics, 2023
A major challenge in the study of active systems is to harness their non-equilibrium dynamics into useful work. We address this by showing how to design colloids with controllable spontaneous propulsion or rotation when immersed in active nematics.

Conformal Equitorsion and Concircular Transformations in a Generalized Riemannian Space

open access: yesMathematics, 2020
In the beginning, the basic facts about a conformal transformations are exposed and then equitorsion conformal transformations are defined. For every five independent curvature tensors in Generalized Riemannian space, the above cited transformations are ...

A Wideband L-Probe Fed Conformal Antenna Array Using Metasurface

open access: yesIEEE Open Journal of Antennas and Propagation, 2021
A wideband conformal metasurface (MTS) antenna array with high gain is designed in this paper. The cooperation of the MTS and L-probe feeding of the antenna element realizes a wide bandwidth of 28.1%, which exhibits only one resonant mode.
