As an important supporting project for the development of western region, the action of prospering the border and enriching the people was officially launched in 1998. Up to now, it has gone through a history of 24 years. The action of prospering the border areas and enriching the people has made China s border areas get rid of poverty and backwardness gradually. Xinjiang Uygur Autonomous Region, located in western China, has been a multi-ethnic region since ancient times. It is not only connected with China s inland provinces, but also an important land route connecting Central Asia, the Middle East and South Asia. The development of Xinjiang is not only related to the smooth development of China s western region, but also related to the continuous advancement of China s national unity, border prosperity and people s prosperity, and the smooth progress of China s Belt and Road Initiative. This paper analyzes the experience of ethnic unity since the founding of the People’s Republic of China in 1949, and on this basis, discusses how to promote ethnic unity in Xinjiang and further promote the smooth progress of the Belt and Road Initiative s construction by prospering the border areas and enriching the people.

Coronary artery disease (CAD) is a major cause of death in the world. As a non-invasive imaging modality, computed tomography angiography (CTA) is now usually used in clinical practice for CAD diagnosis. Precise quantification of coronary stenosis is of great interest for diagnosis and treatment planning. In this paper, a novel cluster method based on a Modified Student’s t-Mixture Model is applied to separate the region of vessel lumen from other tissues. Then, the area of the vessel lumen in each slice is computed and the estimated value of it is fitted with a curve. Finally, the location and the level of the most stenoses are captured by comparing the calculated and fitted areas of the vessel. The proposed method has been applied to 17 clinical CTA datasets and the results have been compared with reference standard degrees of stenosis defined by an expert. The results of the experiment indicate that the proposed method can accurately quantify the stenosis of the coronary artery in CTA.

<P>Energy harvesting from natural environment gives range of benefits for the Internet of things. Scavenging energy from photovoltaic (PV) cells is one of the most practical solutions in terms of power density among existing energy harvesting sources. PV power systems mandate the maximum power point tracking (MPPT) to scavenge the maximum possible solar energy. In general, a switching-mode power converter, an MPPT charger, controls the charging current to the energy storage element (a battery or equivalent), and the energy storage element provides power to the load device. The mismatch between the maximum power point (MPP) current and the load current is managed by the energy storage element. However, such architecture causes significant energy loss (typically over 20%) and a significant weight/volume and a high cost due to the cascaded power converters and the energy storage element. This paper pioneers a converter-less PV power system with the MPPT that directly supplies power to the load without the power converters or the energy storage element. The proposed system uses a nonvolatile microprocessor to enable an extremely fine-grain dynamic power management in a few hundred microseconds. This makes it possible to match the load current with the MPP current. We present detailed modeling, simulation, and optimization of the proposed energy harvesting system including the radio frequency transceiver. Experiments show that the proposed setup achieves an 87.1% of overall system efficiency during a day, 30.6% higher than the conventional MPPT methods in actual measurements, and thus a significantly higher duty cycle under a weak solar irradiance.</P>
