Can Light-Shaped Visual Prompt Promote Individuals’ Lights off Behaviors More Effectively than Ordinary One?  [PDF]
Zhuli Feng, Fuzhen Zhang
Psychology (PSYCH) , 2019, DOI: 10.4236/psych.2019.101006
Abstract: Lights off behavior makes contribution to energy saving, meeting the realistic requirements of building a sustainable society. Several studies investigated the effectiveness of prompt on energy saving behavior, but few focused on how to make prompt more effective by “packaging”. In this current study, light-shaped prompt was designed with inspiration from light itself and 18 washrooms were studied in an ABAB-B method to verify whether the light-shaped visual prompt could promote lights off behaviors more than ordinary one, with a duration of 9 weeks, during which a one-week follow-up was conducted 4 weeks after ABAB was finished, to investigate the sustained effect of light-shaped visual prompt on lights off behaviors. Study showed that light-shaped visual prompt could exert more effective influence on lights off behaviors than the ordinary one. Individuals’ lights off behavior persisted throughout the follow-up period. This study provided a new perspective for improving the effectiveness of prompt. But further study on more well-designed visual prompt of diverse shape was necessary for the maximization of effectiveness and expanded application.
Chomskyan Linguistics and the Scientific Methodology in Linguistic Study
Fuzhen Si
Asian Social Science , 2009, DOI: 10.5539/ass.v5n5p82
Abstract: This article is mainly concerned with Chomskyan linguistics, especially its methodology. The author of the paper argues against Shi Yuzhi(2005) and holds that although the relation between theoretical hypotheses and observations is, in some sense, like chickens and eggs and therefore to say that this paradigm is a top-down approach that is bottom-up one is too simple, theoretical hypothesis does function as directive force in scientific research and can be prerequisite to proper and effective experiments and observations. “Observations are meaningless unless we know what regularity they are supposed to illustrate.” As for the stability of linguistics theory, the author thinks that linguistics, just like other sciences such as chemistry and physics, in order to prove specific ideas and hypothesis, scientists normally change their experimental programs frequently. What changed in Chomksyan linguistics are the experimental programs, the change from Government and Binding theory to the Minimalist Program as an example; what changed are technical details. And the hypothesis and main point of views never changed in general.

Association of ADAM33 gene polymorphisms with adult allergic asthma and rhinitis in a Chinese Han population
Dongju Su, Ximei Zhang, Hong Sui, Fuzhen Lü, Lianhong Jin, Jing Zhang
BMC Medical Genetics , 2008, DOI: 10.1186/1471-2350-9-82
Abstract: Six polymorphic sites (V4, T+1, T2, T1, S1, and Q-1) were genotyped in 128 patients with AR, 181 patients with AS, and 151 healthy controls (CTR). Genotypes were determined by the polymerase chain restriction fragment length polymorphism (PCR-RFLP) method. Data were analyzed using the chi-square test with Haploview software.The single nucleotide polymorphisms (SNPs), V4 G/C, T+1 A/G, and T1 G/A, of the ADAM33 gene may be the causal variants in AR, whereas ADAM33 V4 G/C, T2 A/G, T1 G/A, and Q-1A/G may participate in the susceptibility of AS.These results suggest that polymorphisms of the ADAM33 gene may modify individual susceptibility to AR and AS in a Chinese Han population.Rhinitis is defined as inflammation of the nasal mucosa and is characterised by nasal discharge, blockage, sneezing, and itching [1,2]. Asthma is a chronic inflammatory disorder of the airway which causes recurrent episodes of wheezing, breathlessness, chest tightness, and coughing in susceptible individuals. These episodes are usually associated with widespread, but variable airflow obstruction that is often reversible, either spontaneously or with treatment. The inflammation also causes an associated increase in existing bronchial hyper-responsiveness (BHR) to a variety of stimuli [1,2]. Epidemiologic studies have consistently shown that asthma and rhinitis often coexist in the same patients in every region of the world [3-5], suggesting the concept of 'one airway, one disease.' The basic premise is that rhinitis and asthma represent the manifestations of one syndrome in two parts of the respiratory tract [6]. In order to raise awareness of the theory of 'one airway, one disease,' the Allergic Rhinitis and Its Impact on Asthma (ARIA) Workshop Group publication proposes three considerations for patients with allergic respiratory disease [7].ADAM33 is the first reported asthma-susceptible gene identified by positional cloning [8]. ADAM33 is a complex molecule, the expression of which is largely
Flow-Induced Vibration Analysis of Supported Pipes Conveying Pulsating Fluid Using Precise Integration Method
Long Liu,Fuzhen Xuan
Mathematical Problems in Engineering , 2010, DOI: 10.1155/2010/806475
Abstract: Dynamic analysis of supported pipes conveying pulsating fluid is investigated in Hamiltonian system using precise integration method (PIM). First, symplectic canonical equations of supported pipes are deduced with state variable vectors composed of displacement and momentum. Then, PIM with linear interpolation formula is proposed to solve these equations. Finally, this approach's precision is testified by several numerical examples of pinned-pinned pipes with different fluid velocities and frequencies. The results show that PIM is an efficient and rapid approach for flow-induced dynamic analysis o f supported pipes. 1. Introduction As the pipes are widely used in many industrial fields, flow-induced vibration analysis of pipes conveying fluid has been one of the attractive subjects in structural dynamics. It is well known that pipeline systems may undergo divergence and flutter types of instabilities generated by fluid-structure interaction. Over the last sixty years, extensive studies have been carried out on dynamic analysis of pipeline systems subject to different boundary conditions and loadings. Notable contributions in this area include the works of Chen [1] and Paidoussis [2, 3]. At present, most of the research is concentrated on nonlinear dynamic analysis of pipes conveying pulsating fluid. A recent survey on bifurcations for supported pipes can be found in [4]. Folley and Bajaj [5] considered nonlinear spatial dynamic characteristics of cantilever pipes conveying fluid. In most cases, the corresponding ordinary differential motion equations of fluid-conveyed pipes are deduced using Galerkin’s method in Lagrange system. Then many numerical methods, such as transfer matrix method, finite element method, perturbation method, Runge-Kutta method, and differential quadrature method, are applied to solve these equations. For example, Jensen [6] analyzed dynamic behaviors of vibrating pipe containing fluid subject to lateral resonant base excitation using the perturbation method of multiple scales. Yang et al. [7] investigated the effect of fluid viscosity and mass ratio on instability regions of a Kelvin-type viscoelastic pipe conveying harmonically pulsating fluid using multiple scales method. Wang et al. [8] studied the nonlinear dynamics of curved fluid conveying pipe with differential quadrature method. Jeong et al. [9] proposed a finite element model of pipes conveying periodically pulsating fluid and analyzed the influence of fluid velocities on pipe's stability. Stangl et al. [10] solved the extended version of Lagrange nonlinear equations for

Principal component analysis for spectral indices of stellar populations
Xu Kong,Fuzhen Cheng
Physics , 2001, DOI: 10.1046/j.1365-8711.2001.04301.x
Abstract: We apply the method of principal component analysis to a sample of simple stellar populations to select some age-sensitive spectral indices. Besides the well-known age-sensitive index, H B, we find that some other spectral indices have great potential to determine the age of stellar populations, such as G4300, Fe4383, C24668, and Mgb. In addition, we find that the sensitivity to age of these spectral indices depends on the metallicity of the simple stellar population (SSP): H B and G4300 are more suited to determine the age of the low-metallicity stellar population, C24668 and Mgb are more suited to the high-metallicity stellar population. The results suggest that the principal component analysis method provides a more objective and informative alternative to diagnostics by individual spectral lines.
Effects of Visual Prompt on Recycling Behavior of Waste Batteries  [PDF]
Yuanqing Deng, Fuzhen Zhang
Psychology (PSYCH) , 2019, DOI: 10.4236/psych.2019.1012102
Abstract: Visual prompts are a kind of visual stimulation, through vectors such as text, pictures, bar charts, and image data which guide and persuade individuals to implement expected behaviors. In recent years, with the variety of electronic products and home appliances, the types and usage of batteries are constantly increasing, and the number of corresponding waste batteries is increasing. Because some of the waste batteries contain many heavy metals and electrolyte solutions, which will cause harm to the human body and the ecological environment, more and more people are paying attention to the pollution of waste batteries and their disposal. It has been demonstrated that visual prompts have the effects of protecting the environment. This paper attempts to study the effects of visual prompts on the recycling behavior of waste batteries and verify whether visual prompt has a positive effect on the recycling behavior of waste batteries by using a control group and an experimental group to compare the experimental methods. The visual prompts were pasted on the waste battery recycling bin and were carried out by GraphPad Prism in order to find an economic and effective way to promote people’s recycling behaviors.
An operator equality involving a continuous field of operators and its norm inequalities
Mohammad Sal Moslehian,Fuzhen Zhang
Mathematics , 2008,
Abstract: Let ${\mathfrak A}$ be a $C^*$-algebra, $T$ be a locally compact Hausdorff space equipped with a probability measure $P$ and let $(A_t)_{t\in T}$ be a continuous field of operators in ${\mathfrak A}$ such that the function $t \mapsto A_t$ is norm continuous on $T$ and the function $t \mapsto \|A_t\|$ is integrable. Then the following equality including Bouchner integrals holds \begin{eqnarray}\label{oi} \int_T|A_t - \int_TA_s{\rm d}P|^2 {\rm d}P=\int_T|A_t|^2{\rm d}P - |\int_TA_t{\rm d}P|^2 . \end{eqnarray} This equality is related both to the notion of variance in statistics and to a characterization of inner product spaces. With this operator equality, we present some uniform norm and Schatten $p$-norm inequalities.

Mathematics , 2014,
Abstract: We study the triangle inequalities for angles (with different definitions) and present inequalities concerning the entries of correlation matrices through the positivity of $3\times 3$ matrices. We extend our discussions to the inequalities concerning the triangle triplets with metric-preserving and subadditive functions.
