11,550 flowers, including roses, hydrangea and lilies, were transported on a charted flight from Nairobi and landed in the airport of Changsha, capital of Hunan province, after 14 hours in the air. Kenyan roses are very popular among Chinese consumers due to their high quality and rich variety. Xinhua news release, February 28, 2020
The planet, coded 2007OR10, was discovered in 2007 by three astronomers on the far edge of the solar system, outside Neptune’s orbit. It is one of the reddest celestial bodies found in the Kuiper Belt in the solar system, and it rotates around the sun in an elliptical orbit. Its estimated diameter is1,230 km, and […]
According to the China Academy of Information and Communications Technology (CAICT), China expects over 550,000 5G base stations to be put in operation by the end of 2020. Prefecture-level cities are expected to achieve continuous outdoor connection of the 5G network within this year, with key areas in counties and townships. During the battle against […]
The neutron diffraction device, operated by CAS Institute of High Energy Physics and located in Dongguan, Guangdong Province, has reached its design beam power of 100 kW. In September 2018, the CSNS ran with a power of 20 KW. Its operating beam power had reached 50 KW in January 2019 and 80 KW in October 2019. […]
After launching a project in 2008 with expenditures of 226 million US$, the 4.500 km2 lake in Qinghai Province increased in size, and bird and fish species increased. CAS news release, March 4, 2020
In long-distance practical applications of quantum key distribution (QKD), channel loss is the most serious limiting factor. The existing measurement equipment-independent quantum key distribution (MDI-QKD) uses a two-photon composite event as an effective detection event, so that its secure coding rate decreases linearly with the channel attenuation. In two related studies, PAN Jianwei and colleagues […]
