Fibonacci Congruences and Applications  [PDF]
René Blacher
Open Journal of Statistics (OJS) , 2011, DOI: 10.4236/ojs.2011.12015
Abstract: When we study a congruence T(x) ≡ ax modulo m as pseudo random number generator, there are several means of ensuring the independence of two successive numbers. In this report, we show that the dependence depends on the continued fraction expansion of m/a. We deduce that the congruences such that m and a are two successive elements of Fibonacci sequences are those having the weakest dependence. We will use this result to obtain truly random number sequences xn. For that purpose, we will use non-deterministic sequences yn. They are transformed using Fibonacci congruences and we will get by this way sequences xn. These sequences xn admit the IID model for correct model.

The Origins of Bosons and Fermions  [PDF]
ShaoXu Ren
Journal of Modern Physics (JMP) , 2014, DOI: 10.4236/jmp.2014.517181
Abstract: This paper proposes that all Bosons and all Fermions originate from even more elementary constituents, which called Spin Angular Momentum Vacuum (SAMV). SAMV is filled with Primitive Spin Particles (PSP). The total square spin angular momentum of each PSP is negative, less than zero. Those PSP labeled by index \"\" of Casimir Operator, are called Vacuum Spin Particle (VSP), which could be contracted into so-called Vacuum Bubbles (VB). VB are identical bubbles, are \"sub-observable physical quantities\". VB are paired up into Vacuum Bubble Pair VBP. VSP ωj(or ω+-) results from Self-identical vacuum bubble interaction \"\" through the zero order Phase Transition PT. When the 1st, 2nd, 3rd,... order PT of VBP occur,  then VBP turn into Bosons and Fermions, excited out of sea level of SAMV ocean.
An Integrated Intrusion Detection System by Combining SVM with AdaBoost  [PDF]
Yu Ren
Journal of Software Engineering and Applications (JSEA) , 2014, DOI: 10.4236/jsea.2014.712090
Abstract: In the Internet, computers and network equipments are threatened by malicious intrusion, which seriously affects the security of the network. Intrusion behavior has the characteristics of fast upgrade, strong concealment and randomness, so that traditional methods of intrusion detection system (IDS) are difficult to prevent the attacks effectively. In this paper, an integrated network intrusion detection algorithm by combining support vector machine (SVM) with AdaBoost was presented. The SVM is used to construct base classifiers, and the AdaBoost is used for training these learning modules and generating the final intrusion detection model by iterating to update the weight of samples and detection model, until the number of iterations or the accuracy of detection model achieves target setting. The effectiveness of the proposed IDS is evaluated using DARPA99 datasets. Accuracy, a criterion, is used to evaluate the detection performance of the proposed IDS. Experimental results show that it achieves better performance when compared with two state-of-the-art IDS.
Novel Understanding of Electron States Architecture and Its Dimensionality in Semiconductors  [PDF]
Xiaomin Ren
Optics and Photonics Journal (OPJ) , 2013, DOI: 10.4236/opj.2013.32B075
Abstract:

Some important insights into the electron-states-architecture (ESA) and its dimensionality (from 3 to 0) in a semiconductor (or generally crystalline) material are obtained. The self-consistency of the set of density of states (DOS) expressions with different dimensionalities is remediated through the clarification and rearrangement of the wave-function boundary conditions for working out the eigenvalues in the wave vector space. The actually too roughly observed and theoretically unpredicted critical points for the dimensionality transitions referring to the integer ones are revealed upon an unusual assumption of the intrinsic energy-level dispersion (ELD). The ELD based quantitative physical model had been established on an immediate instinct at the very beginning and has been properly modified afterwards. The uncertainty regarding the relationship between the de Broglie wavelength of electrons and the dimensionality transitions, seeming somewhat mysterious before, is consequentially eliminated. The effect of the material dimensions on the ELD width is also predicted and has been included in the model. The continuous evolution of the ESA dimensionality is convincingly and comprehensively interpreted and thus the area of the fractional ESA dimensionalities is opened. Another new assumption of the spatial extension shrinkage (SES) closely related to the ELD has also been made and thus the understanding of the behavior of an electron or, in a general sense, a particle has become more comprehensive. This work would manifest itself a new basis for further development of nanoheterostructures (or low dimensional heterostructures including the quantum wells, quantum wires, quantum dots and especially the hetero-dimensional structures).

Hurricane Camille 1969 and Storm-Triggered Landslides in the Appalachians and a Perspective in a Warmer Climate  [PDF]
Diandong Ren
International Journal of Geosciences (IJG) , 2016, DOI: 10.4236/ijg.2016.71006
Abstract: This study analyzes storm-triggered landslides in the US Appalachians, in the current geological setting. Concave valleys that favor the convergence of surface runoff are the primary locales for landslides. If the slopes are weathered to the same degree and have the same vegetation coverage, slope orientation (azimuthal) is not critical for slope stability. However, it is found that for the region south of the Black Mountains (North Carolina), north-facing slopes are more prone to slide, because, for the regions not limited by water availability (annual precipitation), the northern slopes usually are grass slopes. For the slopes of the Blue Ridge Mountains, south facing slopes are more prone to slide. Gravity measurements over the past decade reveal that geological conditions, the chute system and underground cracks over the region are stable. Future changes in storm-triggered landslide frequency are primarily controlled by changes in extreme precipitation. Thus, a series of ensemble climate model experiments is carried out to investigate possible changes in future extreme precipitation events, using a weather model forced by atmospheric perturbations from ensemble climate models. Over 50 locations are identified as prone to future landslides. Many of these locales are natural habitats to the Appalachian salamanders. In a future warmer climate, more severe extreme precipitation events are projected because of increased atmospheric water vapor and more frequent passages of tropical cyclone remnants. There is also a likely shift of tropical cyclone tracks and associated extreme precipitations, and the cluster center of Appalachians’s scarps is expected to move westward, with ecological consequences for the endemic salamanders.
The Approach of Accounting Information Quality on Investment Efficiency—Empirical Evidence from Chinese Listed Companies  [PDF]
Chunyan Ren
Theoretical Economics Letters (TEL) , 2016, DOI: 10.4236/tel.2016.62037
Abstract: This paper studies the approach of accounting information quality on investment efficiency, from the context of the Chinese reality system. The empirical results confirm that the proxy for accounting information quality is negatively associated with over-investment or under-investment. Furthermore, there is a negative association between the quality of accounting information and the future investment for firms classified as over-investment and a positive association between the quality of accounting information and the future investment for firms classified as under-investment. The results suggest that the improvement of accounting information quality helps to restrict companies from over-investment and helps the companies to mitigate under-investment.
Analysis of Dual-Core Type City and Its Hinterland Contact Pattern under the Background of High-Speed Rail Networking—Urban Agglomeration in Zhejiang Province as an Example  [PDF]
Xiaohong Ren
Journal of Transportation Technologies (JTTs) , 2016, DOI: 10.4236/jtts.2016.64021
Abstract: Under the background of high-speed rail networking, this paper uses the passenger trains, the type and direction of the railway via Hang Yong and its extension road line, to construct adsorption and dependency index among cities, depict the contact pattern between the Hang Yong dual-core and its hinterland, measure the “net effect” that two center cities (Hangzhou, Ningbo) have on their hinterland, and estimate population agglomeration potential and future possible population flows of Zhejiang Province and the main sample cities. The result shows that, compared with Ningbo, Hangzhou has stronger radiation force to the vast majority of sample cities, and the sample cities affected more by Ningbo mainly concentrates in Ningbo-Taizhou-Wenzhou along; in addition, the sample cities such as Hangzhou, Ningbo and so on show better population agglomeration, then the population “scramble” phenomenon between cities has begun to appear.
There Is a Way to Comprise Half-Integer Eigenvalues for Photon Spin  [PDF]
ShaoXu Ren
Journal of Modern Physics (JMP) , 2016, DOI: 10.4236/jmp.2016.711123
Abstract: In this article, an attempt based on Spin Topological Space, STS, to give areasonable detailed account of the cause of photonic fermionization phenomena of light photon is made. STS is an unconventional spin space in quantum mechanics, which can be used to account for where the unconventional half-integer spin eigenvalues phenomenon of light photon comes from. We suggest to dectect the possible existence of photonic one-third-spinization phenomenon of light photon, by using three beams of light photon in interference experiment.
Vacuum-Matter Interaction through Hyper-Dimensional Time-Space Shifting  [PDF]
René Burri
Journal of High Energy Physics, Gravitation and Cosmology (JHEPGC) , 2016, DOI: 10.4236/jhepgc.2016.23037
Abstract: In the last decade, the need to arrive at a Grand Unification Theory (GUT) has become more and more pressing, being able to open a new matter and universe knowledge. However, the difficulty arises from the fact that new particle discovery shall not resolve the conflict between the various main forces; that is the gravitation and quantum-relativistic theories. It is evident that new players must enter the scene together with extraordinary innovations from a conceptual point of view as they had already been shown in history when the revolutionary Newton and Einstein theories came into the scene. The study presents an attempt to make a connection between quantum1 [1] physics and relativistic theories2 [2] through the introduction of a new item from the peculiar concept of “precursive time”. The analysis was carried out starting from the plausible hypothesis that the time component is the subject of “curvature” as a result of the interaction. For the representation of the model, the geometry of the hypersphere has been applied, which resolves correlations between the imaginary temporal level, devoid of vector coordinates, and the four-dimensional M4 plane.
