This introduction to the singularly perturbed methods in the nonlinear elliptic partial differential equations emphasises the existence and local uniqueness of solutions exhibiting concentration property. The authors avoid using sophisticated estimates and explain the main techniques by thoroughly investigating two relatively simple but typical non-compact elliptic problems. Each chapter then progresses to other related problems to help the reader learn more about the general theories developed from singularly perturbed methods. Designed for PhD students and junior mathematicians intending to do their research in the area of elliptic differential equations, the text covers three main topics. The first is the compactness of the minimization sequences, or the Palais-Smale sequences, or a sequence of approximate solutions; the second is the construction of peak or bubbling solutions by using the Lyapunov-Schmidt reduction method; and the third is the local uniqueness of these solutions.
Journal publication and grant writing are two core professional skills for new scholars today. However, systematic training is not typically offered in graduate programs worldwide. This book equips readers with the current scientific knowledge by providing a concise introduction to the science of journal article publication. The overall structure generally matches the curriculum of a graduate course and each chapter features a learning sequence based on Daniel Kahneman's intuitive judgement theory. The volume analyzes the intuitive thoughts of new authors from a variety of countries, uses over fifty real-life cases, and focuses on core concepts from nearly 100 research articles. It provides scientific advice for new authors, junior researchers, and graduate students to publish their scholarly work and advance their academic careers.
Many scholars perceive ethnic politics in China as an untouchable topic due to lack of data and contentious, even prohibitive, politics. This book fills a gap in the literature, offering a historical-political perspective on China's contemporary ethnic conflict. Yan Sun accumulates research via field trips, local reports, and policy debates to reveal rare knowledge and findings. Her long-time causal chain of explanation reveals the roots of China's contemporary ethnic strife in the centralizing and ethnicizing strategies of its incomplete transition to a nation state—strategies that depart sharply from its historical patterns of diverse and indirect rule. This departure created the institutional dynamics for politicized identities and ethnic mobilization, particularly in the outer regions of Tibet and Xinjiang. In the 21st century, such factors as the demise of socialist tenets and institutions that upheld interethnic solidarity, and the rise of identity politics and developmentalism, have intensified these built-in tensions.
In this paper, CuCr–Zr alloys prepared by vacuum melting with adding La and Ni elementswere heat-treated and aged, followed by plastic deformation using low-energy cyclic impact tests, to simultaneously improve their mechanical and electrical properties. Results showed that the grain size of the casted Cu–Cr–Zr alloys was significantly reduced after the solid-solution aging and plastic deformation process. There were a lot of dispersed Cr and Cu5Zr precipitates formed in the alloys, and the numbers of dislocations were significantly increased. Accordingly, the hardness was increased from 78 to 232 HV, and the tensile strength was increased from 225 to 691 MPa. Electrical conductivity has not been significantly affected after these processes. The enhancement of overall performance is mainly attributed to the combined effects of solid-solution hardening, fine grain hardening, and precipitation/dislocation strengthening.
Glaciers in the eastern Pamir have reportedly been gaining mass during recent decades, even though glaciers in most other regions in High Mountain Asia have been in recession. Questions still remain about whether the trend is strengthening or weakening, and how far the positive balances extend into the eastern Pamir. To address these gaps, we use three different digital elevation models to reconstruct glacier surface elevation changes over two periods (2000–09 and 2000–15/16). We characterize the eastern Pamir as a zone of transition from positive to negative mass balance with the boundary lying at the northern end of Kongur Tagh, and find that glaciers situated at higher elevations are those with the most positive balances. Most (67% of 55) glaciers displayed a net mass gain since the 21st century. This led to an increasing regional geodetic glacier mass balance from −0.06 ± 0.16 m w.e. a−1 in 2000–09 to 0.06 ± 0.04 m w.e. a−1 in 2000–15/16. Surge-type glaciers, which are prevalent in the eastern Pamir, showed fluctuations in mass balance on an individual scale during and after surges, but no statistical difference compared to non-surge-type glaciers when aggregated across the region.
A qualitative interpretive-systemic focus group study was conducted to examine the developmental and implementational underpinnings of Asia's first national Advance Care Planning (ACP) programme constituted in Singapore.
63 physicians, nurses, medical social workers, and allied health workers who actively rendered ACP were purposively recruited across seven major public hospitals and specialist centers.
Framework analysis revealed 19 themes, organized into 5 categories including Life and Death Culture, ACP Coordination, ACP Administration, ACP Outcomes, and Sustainability Shift. These categories and themes formed an Interpretive-Systemic Framework of Sustainable ACP, which reflects the socio-cultural, socio-political, and socio-spiritual contexts that influence ACP provision, highlighting the need to adopt a public health strategy for enhancing societal readiness for end-of-life conversations.
Significance of results
The Interpretive-Systemic Framework of Sustainable ACP underscores the importance of health policy, organizational structure, social discourse, and shared meaning in ACP planning and delivery so as to support and empower care decision-making among terminally ill Asian patients and their families facing mortality.
State-mobilized movements (SMMs) can be found among all regime types, democratic and nondemocratic alike. But certain types of regimes are more likely to generate certain types of SMMs. Communist regimes are partial to proletarian SMMs, calling on the moral authority of the “vanguard revolutionary class” to defuse challenges from other social elements at moments of internal crisis. In light of the signal importance of the proletariat in Marxist-Leninist ideology, it is not surprising that regimes controlled by communist parties should elect to enlist the participation of loyal workers in countermovements intended to delegitimize and demobilize threatening opposition. Unlike repression by the police or military, proletarian action has the advantage of political correctness. Relying on squadrons of workers to neutralize other social forces also promises more pragmatic advantages, especially when the social movement in question is composed largely of students. In responding to contention on the part of idealistic students, whose movements typically generate widespread sympathy among urban residents, intervention by unarmed workers is less apt to alienate the populace than naked military suppression.
