In this thesis, we study the above conjecture on planar graphs. The first chapter provides a literature review of recent developments. The second chapter provides a new proof that the Chen-Lih-Wu Conjecture holds for planar graphs with maximum degree ∆ ≥ 9
Significant anthropogenic-induced changes of climate classes since 1950
No full textAnthropogenic forcings have contributed to global and regional warming in the last few decades and likely affected terrestrial precipitation. Here we examine changes in major Köppen climate classes from gridded observed data and their uncertainties due to internal climate variability using control simulations from Coupled Model Intercomparison Project 5 (CMIP5). About 5.7% of the global total land area has shifted toward warmer and drier climate types from 1950–2010 and significant changes include expansion of arid and high-latitude continental climate zones, shrinkage in polar and midlatitude continental climates, poleward shifts in temperate, continental and polar climates and increasing average elevation of tropical and polar climates. Using CMIP5 multi-model averaged historical simulations forced by observed anthropogenic and natural, or natural only, forcing components, we find that these changes of climate types since 1950 cannot be explained as natural variations but are driven by anthropogenic factors
Attributing observed SST trends and sub-continental land warming to Anthropogenic dorcing during 1979 to 2005
No full textAttribution studies conclude that it is extremely likely that most observed global- and continental-scale surface air temperature (SAT) warming since 1950 was caused by anthropogenic forcing, but some difficulties and uncertainties remain in attribution of warming in subcontinental regions and at time scales less than 50 years. This study uses global observations and CMIP5 simulations with various forcings, covering 1979–2005, and control runs to develop confidence intervals, to attribute regional trends of SAT and sea surface temperature (SST) to natural and anthropogenic causes.Observations show warming, significantly different from natural variations at the 95% confidence level, over one-third of all grid boxes, and averaged over 15 of 21 subcontinental regions and 6 of 10 ocean basins. Coupled simulations forced with all forcing factors, or greenhouse gases only, reproduce observed SST and SAT patterns. Uncoupled AMIP-like atmosphere-only (prescribed SST and atmospheric radiative forcing) simulations reproduce observed SAT patterns. All of these simulations produce consistent net downward longwave radiation patterns. Simulations with natural-only forcing simulate weak warming. Anthropogenic forcing effects are clearly detectable at the 5% significance level at global, hemispheric, and tropical scales and in nine ocean basins and 15 of 21 subcontinental land regions. Attribution results indicate that ocean warming during 1979–2005 for the globe and individual basins is well represented in the CMIP5 multimodel ensemble mean historical simulations. While land warming may occur as an indirect response to oceanic warming, increasing greenhouse gas concentrations tend to be the ultimate source of land warming in most subcontinental regions during 1979–2005
Two-piano performance : its classification, history, and challenges, with a compilation of a detailed catalogue of works
No full textResearch into the art of duo piano playing has been severely neglected. Repertoire is generally incorporated into books on solo piano playing and is often omitted from chamber work listings. With the exception of one outdated, out-of-print book by Hans Moldenhauer, I no author has attempted to submit a recent repertoire listing or a complete examination of the complications of duo pianism. The growth in the number of duos and the increasing number of concerts devoted to their repertoire indicates a previously unmatched public interest in the genre. The aim of this thesis is to serve as a reference guide for educators and pianists, in understanding the classification problems of the duo piano genre and how it relates to other pianistic combinations, an examination of the history of two-piano works until 1950, a look at professional and artistic challenges of duo piano playing, and a catalogue of works written for the medium. Confusion exists about the meaning of the word duet. At issue is whether the genre refers to two pianists at one keyboard exclusively, or whether it incorporates two pianists at two keyboards. Various sources were consulted to show that no uniform definition is available. In this initial chapter background to the study is given, available literature is reviewed and research methodology is explained

Processing Choreography: Thinking with William Forsythe's "Duo"
Full text linkTold from the perspective of the dancers, »Processing Choreography: Thinking with William Forsythe's Duo« is an ethnography that reconstructs the dancers' activity within William Forsythe's Duo project. The book is written legibly for readers in dance studies, the social sciences, and dance practice. Considering how the choreography of Duo emerged through practice and changed over two decades of history (1996-2018), Elizabeth Waterhouse offers a nuanced picture of creative cooperation and institutionalized process. She presents a compelling vision of choreography as a nexus of people, im/material practices, contexts, and relations. As a former Forsythe dancer herself, the author provides novel insights into this choreographic community
Projected shifts in Köppen climate zones over China and their temporal evolution in CMIP5 multi-model simulations
No full textPrevious studies have examined the projected climate types in China by 2100. This study identified the emergence time of climate shifts at a 1◦ scale over China from 1990 to 2100 and investigated the temporal evolution of Köppen–Geiger climate classifications computed from CMIP5 multi-model outputs. Climate shifts were detected in transition regions (7%–8% of China’s land area) by 2010, including rapid replacement of mixed forest (Dwb) by deciduous forest (Dwa) over Northeast China, strong shrinkage of alpine climate type (ET) on the Tibetan Plateau, weak northward expansion of subtropical winterdry climate (Cwa) over Southeast China, and contraction of oceanic climate (Cwb) in Southwest China. Under all future RCP (Representative Concentration Pathway) scenarios, the reduction of Dwb in Northeast China and ET on the Tibetan Plateau was projected to accelerate substantially during 2010–30, and half of the total area occupied by ET in 1990 was projected to be redistributed by 2040. Under the most severe scenario (RCP8.5), sub-polar continental winter dry climate over Northeast China would disappear by 2040–50, ET on the Tibetan Plateau would disappear by 2070, and the climate types in 35.9% and 50.8% of China’s land area would change by 2050 and 2100, respectively. The results presented in this paper indicate imperative impacts of anthropogenic climate change on China’s ecoregions in future decades
Quantifying the dynamics of the interannual variabilities of the wintertime East Asian Jet Core
No full textThe East Asian jet has evident interannual variability in strength and position and has broad impacts on weather and climate in the Asian-Pacific-American region. In this study, we quantify the relative contributions of distinct dynamical processes responsible for the wintertime interannual variability of the East Asian jet core. The quantification is based on analyzing the zonal momentum budgets. Our budget analyses show distinct up- and downstream controls for the interannual intensification of the jet. Over the upstream, the jet intensification is predominantly driven by enhanced upper-level angular momentum transport associated with local convective-driven Hadley-cells. In addition to convections over the Tropical Pacific, those over the Bay of Bengal–South China Sea are found responsible for a distinct local Hadley cell over 80–100 E, which accelerates the jet from its very upstream. Over the downstream, angular momentum advected by the mean flow from the upstream is the first-order term responsible for the jet intensification, whereas synoptic eddies play a secondary role. For the interannual meridional displacement of the jet, synoptic eddy activities over the North Pacific are found to contribute predominantly. For both the intensification and the meridional displacement, the upper-tropospheric jet covaries closely with changes in the Subtropical Oceanic Frontal Zone in the North Pacific. Such a strong covariation implies the contributions of the air–sea interactions to the downstream jet variability
