Alpine glaciers harbor a large quantity of bio-labile dissolved organic matter (DOM), which plays a pivotal role in global carbon cycling as glacial-fed streams are headwaters of numerous large rivers. To understand the complexity, origin, and fate of DOM in glaciers and downstream-linked streams and lakes, we elucidated the molecular composition of DOM in two different Tibetan Plateau glaciers, eight glacial-fed streams and five lakes, using an ultrahigh-resolution 15 Tesla Fourier transform ion cyclotron resonance (FT-ICR) mass spectrometer. The compositional changes of the DOM samples revealed that glacier DOM mostly exhibited sulfur-containing organic compounds (CHOS species). We also found that aliphatic formulae contributed more than 50% of the total abundance of assigned molecules in glacier samples, and those compounds were significantly related to CHOS species. The CHO proportions of glacial-fed streams and lakes samples increased with increasing distance from glacial terminals. The relative contribution of terrestrial-derived organics (i.e., lignins and tannins) declined while microbial-originated organics (aliphatics) increased with increasing elevation. This suggested the gradual input of allochthonous materials from non-glacial environment and the degradation of microbe-derived compounds along lower elevations. Alpine glaciers are retreating as a result of climate change and they nourished numerous streams, rivers, and downstream-linked lakes. Therefore, the interpretations of the detailed molecular changes in glacier ice, glacial-fed streams, and alpine lakes on the Tibetan Plateau could provide broad insights for understanding the biogeochemical cycling of glacial DOM and assessing how the nature of DOM impacts fluvial ecosystems.

From the studies on a few specific chapters of Tibetan Medical Painting, following conclusions were obtained. 1. The doctors of Tibet had to be not only academically and morally perfect, but he must show and have respect for his religion and his religous leaders and Gods. 2 The most main causes for all the disease that Tibetan Medicine resumed were hatred, delusion and ignorance of human mind which can make the physiological bile, wind, and phlegm to turn into pathological ones. 3. There is the classification of primary cause, which would be the human mind mentioned above, and the secondary cause which include dietary, behavior, seasonal problems, etc. 4. The Tibetans thought the digestive power is very important in the improvement or degravation of the disease. 5. More chapters were held for explaining the disease of fever, its clssification, stages, and cures which can indirectly show that the Tibetans might have thought it was very serious and could be very harmful. 6. The treatments for all the kinds of disease not only include medication and external therapy but also dietary and behavior regulations.

Tibet has a long history and many traditions that feature colorful costumes. This study analyzes the similarities and differences in the use of multicolored stripes in the Korean Saekdong (색동: stripes of many colors) and Tibetan folk costumes. The analyses were done within the framework of Tibet's cultural and religious background and the characteristics of the region's traditional costumes. For this study, literature and photographs from books and the Internet that record the history of Tibet's traditional costumes were analyzed. The results show that the use of various colorful stripes was common in the Bangjeon (帮典) apron, one of the greatest costumes in Tibetan history. A Bangjeon is made of wool of multiple colors and has horizontal lines as compared with the silk Saekdong's vertical lines. In addition, they have a multicolored striped band on the sleeves which reminds one of the traditional Korean jacket with its Saekdong sleeves. However, these multicolored stripes appear in more parts of the Saekdong (such as the hemline and front collar) when compared with contemporary Korean costumes. Moreover, the multicolored bands are noticeable in several ornaments from the time, which suggests that Tibetans and Koreans were very fond of using multicolored stripes. Costumes from the Goguryeo (高句麗) dynasty indicate that Tibetans, like the Mongols and Manchus, were very similar to Koreans as they had multicolored garments and Paji pants in common.

Objective: Tibetan chickens, which have unique adaptations to extreme high-altitude environments, exhibit phenotypic and physiological characteristics that are distinct from those of lowland chickens. However, the mechanisms underlying hypoxic adaptation in the liver of chickens remain unknown. Methods: RNA-sequencing (RNA-Seq) technology was used to assess the differentially expressed genes (DEGs) involved in hypoxia adaptation in highland chickens (native Tibetan chicken [HT]) and lowland chickens (Langshan chicken [LS], Beijing You chicken [BJ], Qingyuan Partridge chicken [QY], and Chahua chicken [CH]). Results: A total of 352 co-DEGs were specifically screened between HT and four native lowland chicken breeds. Gene ontology and Kyoto encyclopedia of genes and genomes enrichment analyses indicated that these co-DEGs were widely involved in lipid metabolism processes, such as the peroxisome proliferator-activated receptors (PPAR) signaling pathway, fatty acid degradation, fatty acid metabolism and fatty acid biosynthesis. To further determine the relationship from the 352 co-DEGs, protein-protein interaction network was carried out and identified eight genes (ACSL1, CPT1A, ACOX1, PPARC1A, SCD, ACSBG2, ACACA, and FASN) as the potential regulating genes that are responsible for the altitude difference between the HT and other four lowland chicken breeds. Conclusion: This study provides novel insights into the molecular mechanisms regulating hypoxia adaptation via lipid metabolism in Tibetan chickens and other highland animals.

This paper presents the results of research and analysis with the satellite-derived snow data. It provides the main climatic characteristics of snow cover in China and shows the variation and distribution of snow in regions of Xinjiang, Inter Mongolia and Tibet plateau. The study reveals the vicissitude periods of winter snow cover in Tibetan Plateau by using wavelet analysis with the data from 1980 to 2001. It has about 10 years large period and 3-5 years small period. The analysis shows that the extension of snow increased in recent years in Xinjiang. The results of analysis proves the relationship between winter snow cover in Tibetan Plateau and next summer precipitation in the middle and lower reaches of the Yangtze River. They have good correlation.

Active upwelling air motion in every summer over the Tibetan plateau is an essential process controlling activities of asian summer monsoon which affects water cycle and precipitation in eastern Asia. Large heating rate of surface air on the high plateau with average height of 4000m is considered to cause such large scale upwelling over the plateau. (omitted)

With the globalization of the film industry, ethnic minority films have been developed and studied by many scholars for their special ethnic representation. The film "Tharlo" directed by Pema Tseden carefully explores the identity anxiety of a Tibetan shepherd. Through the connection and separation between the protagonist and traditional culture, it shows a complexity of modern ethnic identity for minority people. This study explores what kind of cinematic techniques and symbolic elements the director uses to shape ordinary characters, build a narrative space, and show ethnic representation. This paper puts forward a theoretical framework combining cinematic quantitative methods with qualitative narrative and semiotic analysis, aiming to deepen our understanding of cinematic techniques and ethnic representation, and provides a new perspective and profound insights for discussing the complexity faced by ethnic minorities in contemporary films. This study finds that Tseden's "Tharlo" successfully portrays the complex transformation of Tibetan cultural identity in the context of globalization and modernization through cinematic techniques such as fixed camera positions, long take and black-and-white cinematography, combined with the use of symbolic elements like mirrors, lambs and identity cards.

Objective: Chinese indigenous sheep breeds can be classified into the following three categories by their tail morphology: fat-tailed, fat-rumped and thin-tailed sheep. The typical sheep breeds corresponding to fat-tailed, fat-rumped, and thin-tailed sheep are large-tailed Han, Altay, and Tibetan sheep, respectively. Detection of copy number variation (CNV) and selection signatures provides information on the genetic mechanisms underlying the phenotypic differences of the different sheep types. Methods: In this study, PennCNV software and F-statistics (F_ST) were implemented to detect CNV and selection signatures, respectively, on the X chromosome in three Chinese indigenous sheep breeds using ovine high-density 600K single nucleotide polymorphism arrays. Results: In large-tailed Han, Altay, and Tibetan sheep, respectively, a total of six, four and 22 CNV regions (CNVRs) with lengths of 1.23, 0.93, and 7.02 Mb were identified on the X chromosome. In addition, 49, 34, and 55 candidate selection regions with respective lengths of 27.49, 16.47, and 25.42 Mb were identified in large-tailed Han, Altay, and Tibetan sheep, respectively. The bioinformatics analysis results indicated several genes in these regions were associated with fat, including dehydrogenase/reductase X-linked, calcium voltage-gated channel subunit alpha1 F, and patatin like phospholipase domain containing 4. In addition, three other genes were identified from this analysis: the family with sequence similarity 58 member A gene was associated with energy metabolism, the serine/arginine-rich protein specific kinase 3 gene was associated with skeletal muscle development, and the interleukin 2 receptor subunit gamma gene was associated with the immune system. Conclusion: The results of this study indicated CNVRs and selection regions on the X chromosome of Chinese indigenous sheep contained several genes associated with various heritable traits.

This paper examined the contemporary kasaya of each country in Asia, focussing on the Kasaya Kongyang ceremony and kasaya varieties. As well, the countries in Asia were divided into the southern Buddhist countries, northern Buddhist countries, and Tibetan buddhist countries, and were comparatively analyzed. 1. In terms of the Kasaya Kongyang ceremony, now days the southern Buddhist countries perform the Katina ceremony, passed down from the time of the Buddha. In the northern Buddhist countries, namely China, the kasaya is bestowed to the monk at the end of the precepts ceremony, while in Korea, the kasaya is bestowed to the monk at the end of the ceremony of "opening the eye" of an image. There is no Kasaya Kongyang ceremony in Japan and Tibetan Buddhist countries. 2. In terms of the varieties of kasaya, because the Katina ceremony is performed with 5 jo in southern Buddhist countries, their kasayas are made up of 5 jo, with the exception of Myanmar's sungari. In Taiwan and Korea, which are of the Zen order and part of the northern Buddhist countries, there are 5-25 jo. In Japan, which is of the Kyo, or doctrinal order, it is made up of 5-9 jo. The Tibetan Buddhist countries have only jo that are 7 and 23. In conclusion, when Buddhism was transmitted from the southern Buddhist countries to the northern Buddhist countries, we can see that the Kasaya Kongyang ceremony and the from of the kasaya itself changed from practical robes to majestic ones, in accord with the Mahayana doctrine of saving all sentient being. Therefore, the kasaya simbolizes the Buddhist philosophy that Mahayana claims the existence of many Buddhas at one and the same time.same time.
