Abstract Purpose An evaluation of the accuracy, safety, and efficiency of the Halcyon ring delivery system (RDS) for stereotactic radiosurgery (SRS) treatment to relatively small (1–3 cm) brain lesions. Methods After completing the extensive in‐house quality assurance checks including Winston–Lutz test and independent dose verification via MD Anderson ...

Ab-initio simulation and experimental validation of beta-titanium alloys [PDF]
In this progress report we present a new approach to the ab-initio guided bottom up design of beta-Ti alloys for biomedical applications using a quantum mechanical simulation method in conjunction with experiments. Parameter-free density functional theory calculations are used to provide theoretical guidance in selecting and optimizing Ti-based alloys ...

Research of Mechanical Properties of Ni-Ti-Nb Alloyson Low Temperature and Restriction Behavior [PDF]
Mechanical Properties of Ni-Ti-Nb alloys with these conditions of cold-drawing, non-vacuum heat treatment and vacuum heat treatment were measured at low temperature, and Mechanical Properties of Ni47Ti44Nb9 alloys of restricting recover was compared with the one of alloys of non-restricting recover, and these rules of the mechanical performance between

Cerebral Amyloid Angiopathy Is Associated With Higher R2 Relaxation Rate: An MRI and Pathology Study
ABSTRACT Objective Cerebral amyloid angiopathy (CAA) involves β‐amyloid deposition in the walls of cortical and leptomeningeal small vessels. Transverse relaxation rate (R2) is a major source of contrast in MRI. This study tested the hypothesis that CAA is associated with R2, extracted the spatial pattern of CAA‐related R2 abnormalities, and evaluated ...

Gamma-irradiation influence on the initial magnetic conductivity of based on the system Fe-Si-B amorphous and nanocrystalline alloys [PDF]
The dependence of initial magnetic permeability {\mu}i of based on the Fe-Si-B amorphous and nanocrystalline alloys on the {\gamma}-irradiation dose was investigated by the method of inductance factor determination. It was determined that the alloying of amorphous Fe-Si-B alloys by nickel and molybdenum increases the radiation sensitivity of the {\mu}i.
