The Non-Perturbative SO(32) Heterotic String

The SO(32) heterotic string can be obtained from the type IIB string by gauging a discrete symmetry that acts as $(-1)^{F_L}$ on the perturbative string states and reverses the parity of the D-string. Consistency requires the presence of 32 NS 9-branes -- the S-duals of D9-branes -- which give SO(32) Chan-Paton factors to open D-strings. At finite string coupling, there are SO(32) charges tethered to the heterotic string world-sheet by open D-strings. At zero-coupling, the D-string tension becomes infinite and the SO(32) charges are pulled onto the world-sheet, and give the usual SO(32) world-sheet currents of the heterotic string.Comment: 12 Pages, Tex, Phyzzx Macr

Medicinal Garden in Peru

Charlotte Trowbridge \u2710 and Josh Ness \u2711 dug in and got their hands dirty when they led a binational team effort to create a medicinal garden at the ancient Chimu site of Chan Chan, Peru, last summer

Here Comes the Sunburst: Measuring and Visualizing Scholarly Impact

Our ARL institution partnered with a new service (PlumX) to track, measure, and visualize faculty scholarly impact. In a pilot project, both traditional and emerging measures of scholarly impact were collected for 32 researchers. The presenters will chronicle the data management and enhancements applied, including utilizing content from our institutional repository, importing and enriching metadata, and using an intranet to organize work and collaborate with colleagues. Results will assist faculty and those who work with them to identify strengths and weaknesses of scholarly impact and where to focus efforts to increase research visibility

Cosmopolitanism, civil disobedience and the global legacy of Martin Luther King

Through the 19th century, the motor of China’s geopolitical change shifted from Eurasia to its southern coast. The impact of the West on China, while resulting in disastrous territorial concessions, also gave rise to a Southern Cosmopolitanism, with Guangdong native, Kang Youwei, becoming a cutting edge figure. 120 years ago, Kang led the first major drive to modernize China in the ill-fated Hundred Days Reform. Three years earlier, in 1895, he organized Gongche Shangshu, the first Chinese “student movement” to petition the royal court for political reform. For many, this activist lineage’s latest manifestation was the Umbrella Movement, Hong Kong’s 79-day Occupy demonstration for universal suffrage in 2014. Following the Arab Spring and a worldwide economic justice movement spearheaded by Occupy Wall Street, the Umbrella Movement originated as a civil disobedience campaign called “Occupy Central with Love and Peace.” One crucial document that inspired Benny Tai, law professor and conceiver of Occupy Central, is Martin Luther King’s “Letter from Birmingham Jail” (1963). The Occupy campaign used the “Birmingham” essay as the foundation for an outstanding civic education initiative drawing upon a global legacy evolved from Thoreau and Gandhi. Evans Chan, New York-based film critic and director of “Raise the Umbrellas” (2016/2018) and acclaimed documentaries about Kang Youwei, explores this early stage of the Umbrella Movement to survey the continuing relevance of King’s legacy in the US, Hong Kong, and the world today. Speaker Born in Guangdong and grew up in Macau and Hong Kong, Evans Chan is an internationally renowned critic, librettist, playwright, and filmmaker. He received his Master’s degree from the New School for Social Research in New York and PhD in Screen Culture at Northwestern University, USA. Currently based in New York, Chan is one of Hong Kong’s leading independent filmmakers. His award-winning films have been shown at the Berlin, Rotterdam, London, Moscow, Vancouver, San Francisco and Taiwan film festivals, among others. In his dramatic and documentary films Chan explores the challenges confronting Hong Kong before and after its return to Chinese rule in 1997. To Liv(e) (1991) was listed as one of the 100 Greatest Hong Kong Films by Time Out Magazine in Hong Kong. Raise the Umbrellas (2016–2018) documents the 79-day massive democratic protests known as the Umbrella Movement in 2014. As a playwright, Chan developed in 2015 his award-winning film Datong: The Great Society (2011) into the libretto as Datong: The Chinese Utopia, which was presented by the Hong Kong Arts Festival and staged in London in 2017. Chan is also a writer whose work has appeared in many Chinese and English publications. His English-language play, adapted from Chinese writer Eileen Chang’s novel Naked Earth, was staged at New York’s Bank Street Theater. Filmography: To Liv(e) (1992), Crossings (1994), Journey to Beijing (1998), Adeus Macau (2000), The Map of Sex and Love (2001), Bauhinia (2002), The Life and Times of Wu Zhongxian (2002), Sorceress of the New Piano: The Artistry of Margaret Leng Tan (2004), Makrokosmos I & II (2004), The Maverick Piano (2007), Datong: The Great Society (2011), Two or Three Things About Kang Youwei (2012), The Rose of the Name: Writing Hong Kong (2014), Raise the Umbrellas (2016), Death in Montmartre (2017). www.evanschan.com Discussant Leo Ou-fan Lee is currently the Sin Wai Kin Professor of Chinese Culture at the Chinese University of Hong Kong. He received his Ph. D. degree from Harvard in 1970 and has taught at Harvard, UCLA, Chicago, Indiana, and Princeton Universities in the United States, as well as the University of Hong Kong and the Hong Kong University of Science and Technology as visiting professor. His scholarly publications in English include: Shanghai Modern: The Flowering of a New Form of Urban Culture, 1930-1945 (Harvard University Press, 1999), Voices from the Iron House: A Study of Lu Xun (Indiana University Press, 1987), The Romantic Generation of Modern Chinese Writers (Harvard, 1973), City between Worlds: My Hong Kong (Harvard University Press, 2008), and Musings: Reading Hong Kong, China and the World (Hong Kong: Muse Books, 2011).

Kinerja Skema Pemberian Tanda Air Video Dijital Berbasis Dwt-svd Dengan Detektor Semi-blind

On the Performance of SVD-DWT Based Digital Video Watermarking Technique with Semi-Blind Detector.This paper presents a watermarking technique for digital video. The proposed scheme is developed based on the workof Ganic and Chan which took the virtue of SVD and DWT. While the previous works of Chan has the blind detectorproperty, our attempt is to develop a scheme with semi-blind detector, by using the merit of the DWT-SDV techniqueproposed by Ganic which was originally applied to still image. Overall, our experimental results show that our proposedscheme has a very good imperceptibility and is reasonably robust especially under several attacks such as compression,blurring, cropping, and sharpening

Cultural Preservation of Ethnomedicine in Peru

In conjunction with the Minority Health & Health Disparities International Research Training program at San Diego State University, three Linfield students contributed to the ongoing Peru Ethnomedical Project in Trujillo, Peru by: Conducting surveys in two neighborhoods on the edge of the city; Creating a medicinal plant garden in the Chan Chan archaeological site museum. Surveys conducted in Moche, Trujillo were part of a larger study supervised by anthropologists Douglas Sharon and Thomas Love. The research aims to evaluate the usage of medicinal plants in rural and urban Peruvian communities. Linfield’s contribution focused on the creation of the medicinal garden to serve as a community model and educational program. The overall purpose of the 2015 summer faculty collaborative project was to: Preserve the knowledge of these practices; Analyze the plant properties; Publish the information; Provide the community with a garden that reflects the commonly used plants; Educate new generations; Bring back and apply this knowledge in the Linfield community

Editing to a Graph of Given Degrees

We consider the Editing to a Graph of Given Degrees problem that asks for a graph G, non-negative integers d,k and a function \delta:V(G)->{1,...,d}, whether it is possible to obtain a graph G' from G such that the degree of v is \delta(v) for any vertex v by at most k vertex or edge deletions or edge additions. We construct an FPT-algorithm for Editing to a Graph of Given Degrees parameterized by d+k. We complement this result by showing that the problem has no polynomial kernel unless NP\subseteq coNP/poly
