Lü (surname)
Lü () is the pinyin (Lǚ with the Tone (linguistics), tone diacritic) and Wade–Giles romanisation of a Chinese surname, most commonly (Simplified Chinese characters, simplified Chinese) and (Traditional Chinese characters, traditional Chinese). Romanization Lü is the standard pinyin spelling of the Chinese character 吕/呂. However, when input of the Umlaut (diacritic), umlaut is not possible, the surname is commonly romanized as Lu or Lv (v being the pinyin input shorthand for ü).

Stephen L
Stephen or Steven is an English first name. It is particularly significant to Christians, as it belonged to Saint Stephen ( ), an early disciple and deacon who, according to the Book of Acts, was stoned to death; he is widely regarded as the first martyr (or " protomartyr") of the Christian Church. The name, in both the forms Stephen and Steven, is often shortened to Steve or Stevie. In English, the female version of the name is Stephanie. Many surnames are derived from the first name, including Stephens, Stevens, Stephenson, and Stevenson, all of which mean "Stephen's (son)". In modern times the name has sometimes been given with intentionally non-standard spelling, such as Stevan or Stevon. A common variant of the name used in English is Stephan ( ); related names that have found some currency or significance in English include Stefan (pronounced or in English), Esteban (often pronounced ), and the Shakespearean Stephano ( ).

Yang Zhongjian
Yang Zhongjian, also Yang Chung-chien (; 1 June 1897 – 15 January 1979), courtesy name Keqiang (), also known as C.C. (Chung Chien) Young, was a Chinese paleontologist and zoologist. He was one of China's foremost vertebrate paleontologists. He has been called the "Father of Chinese Vertebrate Paleontology". Biography Yang was born in Hua County, Shaanxi, China.

Yunnanosaurus
''Yunnanosaurus'' ( ) is an extinct genus of sauropodomorph dinosaur that lived approximately 199 to 183 million years ago in what is now the Yunnan Province, in China, for which it was named. ''Yunnanosaurus'' was a large sized, moderately-built, ground-dwelling, quadrupedal herbivore, that could also walk bipedally, and ranged in size from 7 meters (23 feet) long and 2 m (6.5 ft) high to 4 m (13 ft) high in the largest species. Discovery Yang Zhongjian (also known as C. C. Young) discovered the first ''Yunnanosaurus'' skeletons in the upper Zhangjiawa Member of the Lufeng Formation of Yunnan, People's Republic of China, China, dating to the Sinemurian stage of the Early Jurassic. The fossil find was composed of over twenty incomplete skeletons, including two skulls, it was excavated by Tsun Yi Wang. These remains were the basis for the species ''Y. huangi'' (the type species) and ''Y. robustus.'' In 2007, Lü Junchang and colleagues described an ...

Guangdong
) means "wide" or "vast", and has been associated with the region since the creation of Guang Prefecture in AD 226. The name "''Guang''" ultimately came from Guangxin ( zh, labels=no, first=t, t= , s=广信), an outpost established in Han dynasty near modern Wuzhou, whose name is a reference to an order by Emperor Wu of Han to "widely bestow favors and sow trust". Together, Guangdong and Guangxi are called ''Liangguang, Loeng gwong'' ( zh, labels=no, first=t, t=兩廣, s=两广 , p=liǎng guǎng) During the Song dynasty, the Two Guangs were formally separated as ''Guǎngnán Dōnglù'' ( zh, first=t, t=廣南東路, s=广南东路, l=East Circuit (administrative division), Circuit in Southern Guang , labels=no) and ''Guǎngnán Xīlù'' ( zh, first=t, t=廣南西路, s=广南西路, l=West Circuit (administrative division), Circuit in Southern Guang , labels=no), which became abbreviated as ''Guǎngdōng Lù'' ( zh, first=t, t=廣東路, s=广东路 , labels=no) and ''Guǎngxī Lù ...

Oviraptorid
Oviraptoridae is a group of bird-like, herbivorous and omnivorous maniraptoran dinosaurs. Oviraptorids are characterized by their toothless, parrot-like beaks and, in some cases, elaborate crests. They were generally small, measuring between one and two metres long in most cases, though some possible oviraptorids were enormous. Oviraptorids are currently known only from the Late Cretaceous of Asia, with the most well-known species and complete specimens found only in the Gobi Desert of Mongolia and northwestern China. Description The most characteristic feature of this group is the skull structure. Oviraptorids had short snouts and very deep mandibles. Some taxa (such as ''Citipati'', '' Corythoraptor'', ''Rinchenia'') had a midline crest on top of the skull, resembling that of a cassowary. Other distinguishing characteristics include a bony spike intruding on the mandibular fenestra, nostrils placed very high and far back on the snout, an extremely thin bony bar beneath the e ...

Genus
Genus (; : genera ) is a taxonomic rank above species and below family (taxonomy), family as used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants of an ancestral taxon are grouped together (i.e. Phylogeneti ...

Darwinopterus NT
''Darwinopterus'' (meaning "Darwin's wing") is a genus of pterosaur, discovered in China and named after biologist Charles Darwin. Between 30 and 40 fossil specimens have been identified, all collected from the Tiaojishan Formation, which dates to the middle Jurassic period, 160.89–160.25 Ma ago.Liu Y.-Q. Kuang H.-W., Jiang X.-J., Peng N., Xu H. & Sun H.-Y. (2012). "Timing of the earliest known feathered dinosaurs and transitional pterosaurs older than the Jehol Biota." ''Palaeogeography, Palaeoclimatology, Palaeoecology'' (advance online publication). The type species, ''D. modularis'', was described in February 2010. ''D. modularis'' was the first known pterosaur to display features of both long-tailed ("rhamphorhynchoid") and short-tailed ( pterodactyloid) pterosaurs, and was described as a transitional fossil between the two groups.Dell'Amore, C.

Luchibang
''Luchibang'' (meaning " Lü's heron wing") is an extinct genus of istiodactylid pterosaur discovered in Inner Mongolia, China. The type and only species is ''Luchibang xingzhe''. The genus was initially established on the basis of a supposed nearly complete skeleton and skull, although later analysis of the specimen revealed that it represents a chimera, with the ''Luchibang'' holotype restricted to the end of the snout. Discovery and naming The ''Luchibang'' holotype was acquired from fossil dealers who found it before 2000, possibly near the village of Liutiaogou, in Dashuangmiao of Ningcheng, Inner-Mongolia. Around 2009, David Hone was asked by Xu Xing to describe the specimen, but the article's publication was delayed for many years due to doubts expressed during peer review regarding its authenticity. ''Luchibang'' was announced in an abstract of the Los Angeles ''Flugsaurier'' conference in 2018, but it was only validly published in 2020. In 2020, David W. E. Hone, A ...

Diabetes
Diabetes mellitus, commonly known as diabetes, is a group of common endocrine diseases characterized by sustained high blood sugar levels. Diabetes is due to either the pancreas not producing enough of the hormone insulin, or the cells of the body becoming unresponsive to insulin's effects. Classic symptoms include polydipsia (excessive thirst), polyuria (excessive urination), polyphagia (excessive hunger), weight loss, and blurred vision. If left untreated, the disease can lead to various health complications, including disorders of the cardiovascular system, eye, kidney, and nerves. Diabetes accounts for approximately 4.2 million deaths every year, with an estimated 1.5 million caused by either untreated or poorly treated diabetes. The major types of diabetes are type 1 and type 2. The most common treatment for type 1 is insulin replacement therapy (insulin injections), while anti-diabetic medications (such as metformin and semaglutide) and lifestyle modificatio ...
