The “3 Genomic Numbers” Discovery: How Our Genome Single-Stranded DNA Sequence Is “Self-Designed” as a Numerical Whole  [PDF]
Jean-Claude Perez
Applied Mathematics (AM) , 2013, DOI: 10.4236/am.2013.410A2004
Abstract:

This article proves the existence of a hyper-precise global numerical meta-architecture unifying, structuring, binding and controlling the billion triplet codons constituting the sequence of single-stranded DNA of the entire human genome. Beyond the evolution and erratic mutations like transposons within the genome, it’s as if the memory of a fossil genome with multiple symmetries persists. This recalls the intermingling of information characterizing the fractal universe of chaos theory. The result leads to a balanced and perfect tuning between the masses of the two strands of the huge DNA molecule that constitute our genome. We show here how codon populations forming the single-stranded DNA sequences can constitute a critical approach to the understanding of junk DNA function. Then, we suggest revisiting certain methods published in our 2009 book “Codex Biogenesis”. In fact, we demonstrate here how the universal genetic code table is a powerful analytical filter to characterize single-stranded DNA sequences constituting chromosomes and genomes. We can then show that any genomic DNA sequence is featured by three numbers, which characterize it and its 64 codon populations with correlations greater than 99%. The number “1” is common to all sequences, expressing the second law of Chargaff. The other 2 numbers are related to each specific DNA sequence case characterizing life species. For example, the entire human genome is characterized by three remarkable numbers 1, 2, and Phi = 1.618 the golden ratio. Associated with each of these three numbers, we can match three axes of symmetry, then “imagine” a kind of hyperspace formed by these codon populations. Then we revisit the value (3-Phi)/2 which is probably universal and common to both the scale of quarks and atomic levels, balancing and tuning the whole human genome codon population. Finally, we demonstrate a new kind of duality between “form and substance” overlapping the whole human genome: we will show that—simultaneously with the duality between genes and junk DNA—there is a second layer of embedded hidden structure overlapping all the DNA of the whole human genome, dividing it into a second type of duality information/redundancy involving golden ratio proportions.

The Accounting Analysis of Banking Company: The Case of CAM  [PDF]
Miguel Angel Perez Benedito
Modern Economy (ME) , 2015, DOI: 10.4236/me.2015.62015
Abstract: The measure of management risk has been a constant in Economy in the recent past. This issue is present on any kind of economic or financial activity. The solution adopted for international authorities, increasing liquidity of financial market and generating new indicators to support making decisions, means the continuity of applying the monetary theory as general criteria to solve the actual crisis. In this labyrinth, the manuscript uses the Accounting Methodology of Edgeworth’s Box as a new methodology to measure the management of Banking Companies and analyzes the acquisition of the CAM and Bank Sabadell, two Spanish banking companies. Finally, the manuscript analyzes the financial crisis in Spain through the behavior of listed banking companies in IBEX 35. The manuscript concludes that accounting can explain equilibrium in economy, and it only needs to know how they can be measured properly.
A Quick Survey on Cloud Computing and Associated Security, Mobility and IoT Issues  [PDF]
Michael Perez, Sanjeev Kumar
Journal of Computer and Communications (JCC) , 2017, DOI: 10.4236/jcc.2017.512009
Abstract: This survey paper provides a general overview on Cloud Computing. The topics that are discussed include characteristics, deployment and service models as well drawbacks. Major aspects of Cloud Computing are explained to give the reader a clearer understanding on the complexity of the platform. Following this, several security issues and countermeasures are also discussed to show the major issues and obstacles that Cloud Computing faces as it is being implemented further. The major part of countermeasures focuses on Intrusion Detection Systems. Moving towards Mobile Cloud Computing and Internet of Things, this survey paper gives a general explanation on the applications and potential that comes with the integration of Cloud Computing with any device that has Internet connectivity as well as the challenges that are before it.

Abstract: We give a sufficient condition for finite time blow up of the nonnegative mild solution to a nonautonomous weakly coupled system with fractal diffusion having a time dependent factor which is continuous and nonnegative.
Surfactant Adsorbed at the Oil-Water Interface and Its Elimination  [PDF]
Linfeng Yang, Leonidas Perez Estrada
Journal of Geoscience and Environment Protection (GEP) , 2015, DOI: 10.4236/gep.2015.32007
Abstract:

Surfactants are widely used in the petroleum industry as one kind of Enhanced Oil Recovery methods (EOR). The oil sands mines in Northern Alberta are the largest one in the world. Due to using sodium hydroxide in bitumen extraction process, there are a lot of surfactant molecules in the tailing water. The surfactants from oil sands industry have brought a potential threat to the environment and human health. Depending on the performance of surfactant at the interface, this work focuses on removing these harmful surfactants from the tailing water and not bringing other possible hazardous substances. Moreover, a mathematical model is built to calculate the removal efficiency of the surfactant. The time required for removing the surfactant is determined experimentally. In conclusion, most of surfactant molecules are adsorbed at the oil/water interface. The fraction of the surfactant staying at the oil/water interface is high. Most of the surfactants in tailing water can be eliminated. The time of surfactant migration can be used for setting up the update time of the oil film in the automatic instrument, which can be designed in the future.

The Spin-Foam Approach to Quantum Gravity
Alejandro Perez
Living Reviews in Relativity , 2013,
Abstract: This article reviews the present status of the spin-foam approach to the quantization of gravity. Special attention is payed to the pedagogical presentation of the recently-introduced new models for four-dimensional quantum gravity. The models are motivated by a suitable implementation of the path integral quantization of the Plebanski formulation of gravity on a simplicial regularization. The article also includes a self contained treatment of 2+1 gravity. The simple nature of the latter provides the basis and a perspective for the analysis of both conceptual and technical issues that remain open in four dimensions.
