Our purpose was to ensure that the dose constraints of the organs at risk (OARs) were not exceeded while increasing the prescription dose to the planning target volume (PTV) from 45 to 50.4 Gray (Gy) with the dynamic intensity-modulated radiotherapy (IMRT) technique. While trying for this purpose, a new dynamic IMRT technique named 90° angled collimated dynamic IMRT (A-IMRT) planning was developed by us.

This paper introduces the building method of loosely coupled GPS/INS integrated navigation system. The Euler angles estimation and the velocity constraints are used to improve accuracy. We use MATLAB/Simulink software to simulate and analyze data. The experimental system is built on a low-cost IMU with tri-axis gyroscope, accelerometer and magnetometer and a GPS module to verify the model algorithm. The update rate of the integrated system is equal to the INS rate of 100 Hz and the rate of GPS is 10 Hz.

HD 163296 is one of the few protoplanetary discs displaying rings in the dust component. The present work uses ALMA observations of the 0.9 mm continuum emission, which have significantly better spatial resolution (~8 au) than previously available, to provide new insight into the morphology of the dust disc and its double ring structure. The disc is shown to be thin, and its position angle and inclination with respect to the sky plane are accurately measured as are the locations and shapes that characterise the observed ring-gap structure.

In this paper, an advanced logarithmic phase mask is proposed and its performance is investigated. The essential performance characteristics of phase masks are shown, including the defocused modulation transfer functions (MTF), integral area of the MTF, Hilbert space angle, non-axial Strehl ratio, and decoded images. The results have demonstrated that our phase mask is highly beneficial to extend the depth of field of hybrid optical systems. The advantages of the proposed phase mask in comparison to some other masks are also pointed out.

In this study, the air-plasma generated by radio-frequency was used to treat bamboo fiber. The treatment parameters were studied to find the suitable condition. The testing on tensile strength, tensile modulus, module Weibull and elongation to break of the fiber, the measurement of contact angles and the SEM analysis showed that at the high frequency of 12 kHz, power 50 W and treatment time of 5 minutes, after air-plasma treatment the tensile strength and tensile modulus of bamboo fiber increased more than double (101.1% and 101.
