Refutation and Introspection of Modern Intellectuals on Western Discriminatory Utterances
Haipeng Wang
Asian Culture and History , 2012, DOI: 10.5539/ach.v4n1p73
Abstract: Ever since the modern times, with successive failure of the Qing Government in wars with foreign countries, discriminatory utterances of western countries towards the Chinese nation have been overflowing gradually. These discriminatory utterances have deeply pricked the Chinese patriotic intellectuals, and further stir up their patriotic enthusiasm in saving the nation from subjugation and ensuring its survival. In the anti-imperialist patriotic movement, discriminatory utterances of modern intellectuals have exhibited obviously two trends of resistance and introspection.
Brief Discussion on Missionary and Transition of Modern Chinese Customs
Haipeng Wang
Asian Social Science , 2011, DOI: 10.5539/ass.v7n3p249
Abstract: Ever since the modern society, the large differences between Chinese and western customs have seriously obstructed dissemination of Christianity in China. Thus, missionaries who came to China paid great attention to observation and study on social customs in China. The serious condition in modern Chinese social customs has aroused deep concern of some missionaries who have profound understanding in Chinese culture who start from social customs, vigorously propagandize the concept that “only Christianity is able to save China” and meanwhile, hold a series of activities to modify undesirable customs in China, which has led to important effects upon transition of modern Chinese social customs.
Enhancing Programming Interface to Effectively Meet Multiple Information Needs of Developers
Haipeng Cai
Computer Science , 2015,
Abstract: In the past decades, integrated development environments (IDEs) have been largely advanced to facilitate common software engineering tasks. Yet, with growing information needs driven by increasing complexity in developing modern high-quality software, developers often need to switch among multiple user interfaces, even across different applications, in their development process, which breaks their mental workflow thus tends to adversely affect their working efficiency and productivity. This position paper discusses challenges faced by current IDE designs mainly from working context transitions of developers during the process of seeking multiple information needs for their development tasks. It remarks the primary blockades behind and initially explores some high-level design considerations for overcoming such challenges in the next-generation IDEs. Specifically, a few design enhancements on top of modern IDEs are envisioned, attempting to reduce the overheads of frequent context switching commonly seen in the multitasking of developers.
Inferring the Demographic History and Rate of Adaptive Substitution in Drosophila
Haipeng Li ,Wolfgang Stephan
PLOS Genetics , 2006, DOI: 10.1371/journal.pgen.0020166
Abstract: An important goal of population genetics is to determine the forces that have shaped the pattern of genetic variation in natural populations. We developed a maximum likelihood method that allows us to infer demographic changes and detect recent positive selection (selective sweeps) in populations of varying size from DNA polymorphism data. Applying this approach to single nucleotide polymorphism data at more than 250 noncoding loci on the X chromosome of Drosophila melanogaster from an (ancestral) African population and a (derived) European, we found that the African population expanded about 60,000 y ago and that the European population split off from the African lineage about 15,800 y ago, thereby suffering a severe population size bottleneck. We estimated that about 160 beneficial mutations (with selection coefficients s between 0.05% and 0.5%) were fixed in the euchromatic portion of the X in the African population since population size expansion, and about 60 mutations (with s around 0.5%) in the diverging European lineage.
Understanding atomic-scale phase separation of liquid Fe-Cu alloy
HaiPeng Wang,BingBo Wei
Chinese Science Bulletin , 2011, DOI: 10.1007/s11434-011-4739-x
Abstract: Using liquid Fe60Cu40 alloy as a model, the structure of liquid Fe-Cu alloy systems is investigated in the temperature range 1200–2200 K, covering a large metastable undercooled regime, to understand the phase separation of liquid Fe-Cu alloys on the atomic scale. The total pair distribution functions (PDFs) indicate that liquid Fe60Cu40 alloy is ordered in the short range and disordered in the long range. If the atom types are ignored, the total atom number densities and PDFs demonstrate that the atoms are distributed homogenously in the liquid alloy. However, the segregation of Fe and Cu atoms is very obvious with decreasing temperature. The partial PDFs and coordination numbers show that the Cu and Fe atoms are not apt to get together on the atomic scale at low temperatures; this will lead to large fluctuations and phase separation in liquid Fe-Cu alloy.
Surface tension and specific heat of liquid Ni70.2Si29.8 alloy
Wang Haipeng,Wei Bingbo
Chinese Science Bulletin , 2005, DOI: 10.1360/982004-475
Abstract: The surface tension and specific heat of stable and metastable liquid Ni70.2Si29.8 eutectic alloy were measured by electromagnetic levitation oscillating drop method and drop calorimetry. The surface tension depends on temperature linearly within the experimental undercooling regime of 0–182 K (0.12 TE). Its value is 1.693 N-m 1 at the eutectic temperature of 1488 K, and the temperature coefficient is-4.23×10 4 N-m 1.K 1. For the specific heat measurement, the maximum undercooling is up to 253 K (0.17 TE). The specific heat is determined as a polynomial function of temperature in the experimental temperature regime. On the basis of the measured data of surface tension and specific heat, the temperature-dependent density, excess volume and sound speed of liquid Ni70.2Si29.8 alloy are predicted theoretically.
Homemade Experimental Platform Used in Major Course Experiment Class
Minming Gu,Haipeng Pan
Education Research Frontier , 2012,
Abstract: This paper discusses the effect of homemade experiment instrument in the laboratory construction and the experimental teaching reform. Firstly this paper analyzes the necessity and feasibility of the homemade experiment platform. Then taking embedded motor control experimental platform as an example, it introduces the operation of the Institute of automation, whose teachers combine scientific research with practical teaching and turn the achievements into laboratory construction and students' practical teaching to initiative the students’ study interest. By changing the teaching concept, introducing new teaching mode, improving the experimental approaches and combing with the basic theory of embedded motor control, theory teaching and experimental teaching are integrated organically via the homemade experiment platform. Thus, students can better master the relevant knowledge of motor control, and their innovation ability and comprehensive abilities can be strengthened.
Bounds on the Outage-Constrained Capacity Region of Space-Division Multiple-Access Radio Systems
Jin Haipeng,Acampora Anthony
EURASIP Journal on Advances in Signal Processing , 2004,
Abstract: Space-division multiple-access (SDMA) systems that employ multiple antenna elements at the base station can provide much higher capacity than single-antenna-element systems. A fundamental question to be addressed concerns the ultimate capacity region of an SDMA system wherein a number of mobile users, each constrained in power, try to communicate with the base station in a multipath fading environment. In this paper, we express the capacity limit as an outage region over the space of transmission rates from the mobile users. Any particular set of rates contained within this region can be transmitted with an outage probability smaller than some specified value. We find outer and inner bounds on the outage capacity region for the two-user case and extend these to multiple-user cases when possible. These bounds provide yardsticks against which the performance of any system can be compared.
Baryogenesis Once More, Inside LHC
Haipeng An,Yue Zhang
Physics , 2013,
Abstract: We investigate the feasibility of directly detecting a generation mechanism of the cosmic baryon asymmetry, by repeating the same particle physics process inside the LHC. We propose a framework with R-parity and CP violating squark decays responsible for baryogenesis, which can be embedded in supersymmetric models and is partly motivated by naturalness. We argue that the baryon number generation here is closely related to lepton charge asymmetry on the resonance. We emphasize the importance of the single charged lepton plus multijet channel in the absence of significant missing energy in search of such a scenario.
Coalescent Tree Imbalance and a Simple Test for Selective Sweeps Based on Microsatellite Variation
Haipeng Li,Thomas Wiehe
PLOS Computational Biology , 2013, DOI: 10.1371/journal.pcbi.1003060
Abstract: Selective sweeps are at the core of adaptive evolution. We study how the shape of coalescent trees is affected by recent selective sweeps. To do so we define a coarse-grained measure of tree topology. This measure has appealing analytical properties, its distribution is derived from a uniform, and it is easy to estimate from experimental data. We show how it can be cast into a test for recent selective sweeps using microsatellite markers and present an application to an experimental data set from Plasmodium falciparum.
