Broadside High Index Dielectric Beam Routing [PDF]
arXiv, 2017 We propose a technique to control the beam direction of a dielectric optical micro-prism structure by properly designing its geometry. We show that by selectively choosing the slope of a high index micro prism, the direction of the radiated beam from the tip can be controlled in the broadside direction of the prism structure.

Patient‐specific adaptive planning margin for whole bladder radiation therapy
Journal of Applied Clinical Medical Physics, EarlyView.Abstract Background Whole bladder irradiation is an organ preservation treatment approach for muscle‐invasive bladder cancer (MIBC). Conventional planning margins, typically 15–20 mm, increase normal tissue toxicity and limit possible dose escalation.

arXiv, 2009 In this Letter we propose the concept of the evanescent Airy beam. We analyze the structure of the ideal evanescent Airy beam, which initial profile has the Airy form, while the spectral decomposition consists of only evanescent partial waves. Also, we discuss the refraction of the Airy beam through the interface and investigate the field of the ...

Study of Passive Vibration Absorbers Attached on Beam Structure
, 2014 Structural vibration is undesirable, wasting energy and possibly leading to excessive deflections and structure and machine’s failure. In order to reduce structural vibration, one of the common way is considering vibration absorber system attach to the ...

New tools for automated high-resolution cryo-EM structure determination in RELION-3
eLife, 2018 Here, we describe the third major release of RELION. CPU-based vector acceleration has been added in addition to GPU support, which provides flexibility in use of resources and avoids memory limitations.

Journal of Applied Clinical Medical Physics, EarlyView.Abstract This study aimed to compare the treatment plans of x‐ray SBRT and scanning carbon ion radiation therapy (CIRT) for localized lung tumors, and to evaluate the dose dependence of tumor size tumor‐to‐heart distance. For phantom verification, we used a chest phantom with a spherical simulated tumor.

AAPM‐RSS Medical Physics Practice Guideline 9.b: SRS‐SBRT
Journal of Applied Clinical Medical Physics, EarlyView.Abstract The purpose of this Medical Physics Practice Guideline (MPPG) is to describe the minimum level of medical physics support deemed prudent for the practice of linear‐accelerator, photon‐based (linac) stereotactic radiosurgery (SRS), and stereotactic body radiation therapy (SBRT) services.

International Journal of Optics, 2012 Anomalous beam propagation in low index-contrast metamaterials has been analyzed. The condition for a well-collimated beam is found to be depending on the beam width and the pertinent Fourier component of the dielectric function. Guided by this condition,
