Convergence Rates of Density Estimation in Besov Spaces  [PDF]
Huiying Wang
Applied Mathematics (AM) , 2011, DOI: 10.4236/am.2011.210175
Abstract: The optimality of a density estimation on Besov spaces Bsr,q(R) for the Lp risk was established by Donoho, Johnstone, Kerkyacharian and Picard (“Density estimation by wavelet thresholding,” The Annals of Statistics, Vol. 24, No. 2, 1996, pp. 508-539.). To show the lower bound of optimal rates of convergence Rn(Bsr,q, p), they use Korostelev and Assouad lemmas. However, the conditions of those two lemmas are difficult to be verified. This paper aims to give another proof for that bound by using Fano’s Lemma, which looks a little simpler. In addition, our method can be used in many other statistical models for lower bounds of estimations.

Huiying Zheng
Art and Design Review (ADR) , 2019, DOI: 10.4236/adr.2019.72008
Abstract: Scientifically designed dual language books are the premise and basis for ensuring smooth bilingual teaching. To design dual language books for children in Britain, it is necessary to fully consider the practicality of their books and meet the actual needs of schools. The dual language books should be easy to learn and teach, practical and interesting, so as to meet the bilingual learning needs of British children. This essay will cut into the resources of the UK’s major language communities and discuss the various factors that influence the design of dual language books, and related issues identified by the research project.
Isospin Symmetry Breaking in the Chiral Quark Model
Huiying Song,Xinyu Zhang,Bo-Qiang Ma
Physics , 2010, DOI: 10.1103/PhysRevD.82.113011
Abstract: We discuss the isospin symmetry breaking (ISB) of the valence- and sea-quark distributions between the proton and the neutron in the framework of the chiral quark model. We assume that isospin symmetry breaking is the result of mass differences between isospin multiplets and then analyze the effects of isospin symmetry breaking on the Gottfried sum rule and the NuTeV anomaly. We show that, although both flavor asymmetry in the nucleon sea and the ISB between the proton and the neutron can lead to the violation of the Gottfried sum rule, the main contribution is from the flavor asymmetry in the framework of the chiral quark model. We also find that the correction to the NuTeV anomaly is in an opposite direction, so the NuTeV anomaly cannot be removed by isospin symmetry breaking in the chiral quark model. It is remarkable that our results of ISB for both valence- and sea-quark distributions are consistent with the Martin-Roberts-Stirling-Thorne parametrization of quark distributions.
Light flavor asymmetry of nucleon sea
Huiying Song,Xinyu Zhang,Bo-Qiang Ma
Physics , 2011, DOI: 10.1140/epjc/s10052-011-1542-4
Abstract: The light flavor antiquark distributions of the nucleon sea are calculated in the effective chiral quark model and compared with experimental results. The contributions of the flavor-symmetric sea-quark distributions and the nuclear EMC effect are taken into account to obtain the ratio of Drell-Yan cross sections $\sigma^{\mathrm{pD}}/2\sigma^{\mathrm{pp}}$, which can match well with the results measured in the FermiLab E866/NuSea experiment. The calculated results also match the measured $\bar{d}(x)-\bar{u}(x)$ from different experiments, but unmatch the behavior of $\bar{d}(x)/\bar{u}(x)$ derived indirectly from the measurable quantity $\sigma^{\mathrm{pD}}/2\sigma^{\mathrm{pp}}$ by the FermiLab E866/NuSea Collaboration at large $x$. We suggest to measure again $\bar{d}(x)/\bar{u}(x)$ at large $x$ from precision experiments with careful experimental data treatment. We also propose an alternative procedure for experimental data treatment.

Abstract:

In recent years, with the rapid development of economy and the continuous advancement of technology, the demand for high-level talents with expertise has been gradually increased in China. Master of Engineering (ME), the new education mode, has been developed rapidly. After briefing the status quo of the ME degree programs at home and abroad, this paper examines the current status of Master of Engineering degree programs in China from four aspects, namely the curriculum planning, graduation requirements, mentor qualities and the education system, by analyzing the results of a survey conducted in China’s universities. After pointing out the problems existed in the ME degree programs, this paper put forward four pieces of corresponding suggestions.

Network Misconduct of College Students and Regulatory Emotional Self-Efficacy  [PDF]
Huiying Liu, Bian Du
Open Journal of Social Sciences (JSS) , 2014, DOI: 10.4236/jss.2014.25023
Abstract: Purposes: Analyze characteristics of network misconduct of college students and study its correlation with regulatory emotional self-efficacy through scale survey of network misconduct of college students. Methods: Conduct the test on 1321 college students by using the scale of network misconduct and regulatory emotional self-efficacy of college students. SPSS was used to compile effective data. Statistical analysis was made using descriptive statistics, independent sample t test and one-way analysis of variance. Results: 1) M ± SD for network words anomie, study anomie and infringement are: 8.76 ± 2.07; 7.40 ± 2.17; 5.21 ± 2.16. 2) There are significant differences of network misconduct of college students on genders, education levels, majors and grades. (t = 12.510, p < 0.001; t = 50.957, P < 0.001; t = 23.840, p < 0.001; t = 28.576, P < 0.001). 3) Conclusions of significantly negative correlation between regulatory emotional self-efficacy and network misconduct (r = -0.134, p < 0.01). For college student, network misconduct includes network words anomie, study anomie and infringement behavior, among which, network words anomie is more prominent; and self-efficacy concerning college students’ emotion regulation has significantly negative correlation with network misconduct.

系统科学与数学 , 2008,
Abstract: A proper edge coloring of the graph G is called adjacent vertex distinguishing acyclic edge coloring, if there is no 2-colored cycle in G, and the coloring set of edges incident to u is not equal to the coloring set of edges incident to v, whereuv\in E(G). In this paper, a new upper bound of adjacent vertex distinguishing acyclic edge coloring of the graph G with no isolated edges is obtained by the way of probability.

PLOS ONE , 2013, DOI: 10.1371/journal.pone.0065733
Abstract: Cathepsin D (CD) plays an important role in both biological and pathological processes, although the cleavage characteristics and substrate selection of CD have yet to be fully explored. We employed liquid chromatography-tandem mass spectrometry (LC-MS/MS) to identify the CD cleavage sites in bovine serum albumin (BSA). We found that the hydrophobic residues at P1 were not only a preferential factor for CD cleavage but that the hydrophobicity at P1’ also contributed to CD recognition. The concept of hydrophobic scores of neighbors (HSN) was proposed to describe the hydrophobic microenvironment of CD recognition sites. The survey of CD cleavage characteristics in several proteins suggested that the HSN was a sensitive indicator for judging the favorable sites in peptides for CD cleavage, with HSN values of 0.5–1.0 representing a likely threshold. Ovalbumin (OVA), a protein resistant to CD cleavage in its native state, was easily cleaved by CD after denaturation, and the features of the cleaved peptides were quite similar to those found in BSA, where a higher HSN value indicated greater cleavability. We further conducted two-dimensional gel electrophoresis (2DE) to find more proteins that were insensitive to CD cleavage in CD-knockdown cells. Based on an analysis of secondary and three-dimensional structures, we postulated that intact proteins with a structure consisting of all α-helices would be relatively accessible to CD cleavage.
Towards a Methodology for the Differential Analysis in Human Locomotion: A Pilot Study on the Participation of Individuals with Multiple Sclerosis  [PDF]
Huiying Yu, Thompson Sarkodie-Gyan
Engineering (ENG) , 2012, DOI: 10.4236/eng.2012.410B006
Abstract:

Multiple sclerosis (MS) is an unpredictable disease of the central nervous system that can range from relatively benign to somewhat disabling to devastating, as communication between the brain and other parts of the body is disrupted. Scientists have learned a great deal about MS in recent years; yet still, its cause remains elusive. This paper intends to investigate the hypothesis that gait dynamics have meaning and may be useful in providing insight into the neural control of locomotion. It further seeks to explore the mutual interactions and influences of MS functions on gait, and vice versa, in a quantitative and robust fashion. Ground reaction forces (GRFs), muscle activities, and segmental accelerations within a gait cycle were analyzed in this study. Patterns of the signals from six relapsing-remitting multiple sclerosis (RRMS) patients were compared with the healthy subjects. This quantitative gait analysis aids to illuminate a better understanding of the mobility-related disease such as RRMS characteristics. An outcome of this study is a reproducible methodology for helping therapists make reliable and differentiable diagnosis, design a tailored therapeutic strategy, and comfortably evaluate the follow-ups on patient’s functional recovery.
