Sinohelicoprion (meaning "Chinese spiral saw" or "Chinese Helicoprion ") is an extinct genus of helicoprinid eugeneodontid fish that lived during the late Permian and possibly the Early Triassic, from 254 to 251 million years ago. [1] [2]
It was first named and classified by H. T. Liu and M. N. Chang in 1963. [3] [4]

Banpo is a Neolithic archaeological site located in the Yellow River valley, east of present-day Xi'an, China. Discovered in 1953 by Shi Xingbang, the site represents the first phase of the Yangshao culture and features the remains of several well organized settlements—including Jiangzhai, which has been radiocarbon dated to c. 4700 – c. 3600 BCE). An area of 5 to 6 hectares was surrounded by a ditch, probably a defensive moat 5 to 6 meters wide. The houses at Banpo were circular, built of mud and wood on low foundations, with overhanging thatched roofs. There also appear to have been communal burials.

This comparison of orbital launch systems lists the attributes of all current and future individual rocket configurations designed to reach orbit. A first list contains rockets that are operational or have attempted an orbital flight attempt as of 2024; a second list includes all upcoming rockets. For the simple list of all conventional launcher families, see: Comparison of orbital launchers families. For the list of predominantly solid-fueled orbital launch systems, see: Comparison of solid-fueled orbital launch systems.
Jianghanichthys is an extinct genus of freshwater cypriniform fish from the Late Paleocene to Early Eocene of central and southern China, and the only member of the family Jianghanichthyidae. It is the oldest cypriniform fish known from body fossils, and the most basal known cypriniform.
Morris Chang is an American businessman and electrical engineer, originally from Ningbo, China. He built his business career first in the United States and then subsequently in Taiwan. He is the founder and former chairman and CEO of Taiwan Semiconductor Manufacturing Company (TSMC). He is regarded as the founder of Taiwan's semiconductor industry.

Meemann Chang also known as Zhang Miman, is a Chinese paleontologist at the Institute of Vertebrate Paleontology and Paleoanthropology (IVPP). She completed her undergraduate studies at Moscow University and completed her PhD thesis entitled 'The braincase of Youngolepis, a Lower Devonian crossopterygian from Yunnan, south-western China' at Stockholm University. She was the first woman to become head of IVPP in 1983. For her many career achievements, she received an honorary degree from the University of Chicago in 2011 and the Romer-Simpson Medal from the Society of Vertebrate Paleontology in 2016.
The Taipei Representative Office in the UK is a liaison office of Taiwan in the United Kingdom. It is not a fully-fledged diplomatic mission owing to the ongoing Taiwan dispute and One-China policy. However, it is the highest-level representation of the Taiwan authority in the United Kingdom. It manages cultural, economic and political cooperation between the UK and Taiwan, as well as offering consular services. Its counterpart body in Taiwan is the British Office Taipei.

Pan Jianwei is a Chinese academic administrator and quantum physicist. He is a university administrator and professor of physics at the University of Science and Technology of China. Pan is known for his work in the field of quantum entanglement, quantum information and quantum computers. In 2017, he was named one of Nature's 10, which labelled him "Father of Quantum". He is an academician of the Chinese Academy of Sciences and the World Academy of Sciences and Executive Vice President of the University of Science and Technology of China. He also serves as one of the Vice Chairman of Jiusan Society.
The Dark Matter Particle Explorer, or DAMPE, also known as Wukong, is a Chinese Academy of Sciences (CAS) satellite which launched on 17 December 2015. The satellite was launched on a Long March 2D rocket from Launch Pad 603 at the LC-43 complex, also known as the South Launch Site, at the Jiuquan Satellite Launch Center. It is China's first space observatory.
The borate fluorides or fluoroborates are compounds containing borate or complex borate ions along with fluoride ions that form salts with cations such as metals. They are in the broader category of mixed anion compounds. They are not to be confused with tetrafluoroborates (BF4) or the fluorooxoborates which have fluorine bonded to boron.
The borate carbonates are mixed anion compounds containing both borate and carbonate ions. Compared to mixed anion compounds containing halides, these are quite rare. They are hard to make, requiring higher temperatures, which are likely to decompose carbonate to carbon dioxide. The reason for the difficulty of formation is that when entering a crystal lattice, the anions have to be correctly located, and correctly oriented. They are also known as carbonatoborates or borocarbonates. Although these compounds have been termed carboborate, that word also refers to the C=B=C5− anion, or CB11H12− anion. This last anion should be called 1-carba-closo-dodecaborate or monocarba-closo-dodecaborate.
The sulfate fluorides are double salts that contain both sulfate and fluoride anions. They are in the class of mixed anion compounds. Some of these minerals are deposited in fumaroles.
The borate chlorides are chemical compounds that contain both borate ions and chloride ions. They are mixed anion compounds. Many of them are minerals. Those minerals that crystallise with water (hydrates) may be found in evaporite deposits formed when mineral water has dried out.
Sulfidostannates, or thiostannates are chemical compounds containing anions composed of tin linked with sulfur. They can be considered as stannates with sulfur substituting for oxygen. Related compounds include the thiosilicates, and thiogermanates, and by varying the chalcogen: selenostannates, and tellurostannates. Oxothiostannates have oxygen in addition to sulfur. Thiostannates can be classed as chalcogenidometalates, thiometallates, chalcogenidotetrelates, thiotetrelates, and chalcogenidostannates. Tin is almost always in the +4 oxidation state in thiostannates, although a couple of mixed sulfides in the +2 state are known,
Liu Kwang-ching, who sometimes published under the name K.C. Liu, was a Chinese-born American historian of China. He taught at University of California-Davis from 1963 until his retirement in 1993. He is best known for his scholarship in late-Qing history, astute bibliographical work, and edited volumes, including co-editing Cambridge History of China volumes.
