Abstract: This paper discovered for the first time a new mathematical infinite construction set and " the symmetric and asymmetric, random and non-random balanced exchange combination mechanism of the even-number 'infinity axiom' ". It is called "dimensionless circular logarithm". The circular logarithm axiomatization is proposed: the group combination itself divided by itself is not necessarily 1, which resolves the difficulty of "multiplication combination and addition combination" cannot be integrated. Regarding sensitive topics such as algebra-geometry-number theory-group combination: axiomatization, continuum, four color theorem, category theory, Riemann zero conjecture, Langlands program, elementary particles, etc., a simple circular logarithm formula is used to unify the analysis and solution in { 0, ±1} . Important calculation example: "neutrinos, quarks, Higgs particles" are connected with dimensionless construction sets, describing the "central zero point-Higgs particle" with the 'infinity axiom' to drive the cyclic evolution mechanism of the universe-mathematical world.

Abstract: Differential equations have proven to be an immensely successful instrument for modeling phenomena in science and technology. It is hardly an exaggeration to say that differential equations are used to define mathematical models in virtually all parts of the natural sciences. In this document, we will take the first steps towards learning how to deal with differential equations on a computer. This is a core issue in Computational Science and reaches far beyond what we can cover in this text. However, the ideas you will see here are reused in lots of advanced applications, so this document will hopefully provide useful introduction to a topic that you will probably encounter many times later. We will show you how to build programs for solving differential equations. More precisely, we will show how a differential equation can be formulated in a discrete manner suitable for analysis on a computer, and how to implement programs to compute the discrete solutions. The simplest differential equations can be solved analytically in the sense that you can write down an explicit formula for the solutions. However, differential equations arising in practical applications are usually rather complicated and thus have to be solved numerically on a computer. Therefore we focus on implementing numerical methods to solve the equations. The document Programming of ordinary differential equations  describes more advanced implementation techniques aimed at making an easy-to-use toolbox for solving differential equations. Exercises in the present document and the mentioned document aim at solving a variety of differential equations arising in various disciplines of science.

Abstract: Background: In regards to the increased prevalence of cardiovascular diseases (CVDs), various factors, including intercellular adhesion molecule-1 (ICAM-1), leptin, lipid profile, and body mass index (BMI) can be considered as major risk factors of these diseases. The purpose of this study was to investigate the effect of an 8-week aerobic exercise on ICAM-1 levels, serum leptin levels, HDL/LDL ratio, and BMI in middle-aged women. Materials and Methods: Twenty-five healthy women in the age range of ± 3.25 to 42.26 with no past history of diseases participated in this quasi-experimental study. Further, 13 subjects were assigned as experimental group and 12 as control group. The experimental group had 40-min cumulative aerobic exercise sessions three times a week for 8 weeks. The exercises were aimed to raise their heart rate between 60 to 75% of their maximum heart rate. ICAM-1 levels, serum leptin levels, HDL/LDL ratio and BMI were measured both before and after the exercises. Results: The result showed a significant decrease in ICAM-1 levels (p = 0.005), serum leptin (p = 0.008), HDL/LDL ratio and BMI (p = 0.001). An independent t-test was used to analyze the data. Discussions.: As the body ages the risk for cardiovascular disease and atherosclerosis increases, so regular aerobic exercise with its significant impact on the cardiovascular risk factor reduction can be a suitable tool for preventing the progression of these diseases, especially in the middle aged.

Abstract: Processor allocation is responsible for selecting a set of processors in order to run parallel work on them, while job schedule is responsible for determination of executing works. Job Schedule selects the next job for execution based on stated policy and then the processor allocation algorithm finds the free processors for the selected work. Until now, several continuous and non continuous techniques have been given for processor allocation in mesh multi-computers networks. Continuous allocation methods always try to allocate a free continuous sub-mesh with the same requested dimensional structure to the parallel input job. For this reason, it produces the internal fragmentation in the processors network. Non continuous allocation algorithms were produced with the aim of removing processors fragmentation. In discontinuous allocation algorithms, message interference between different jobs and strugle to get communication resources increases network communication overheads due to the increase in path length passed by the message. This communication overhead is highly dependent on to the manner of free sub-meshes allocation and the manner of recording by the algorithm. This reasearch, a non continuous allocation algorithm called Efficient and Quick Non-Continuous Allocation (EQNA) algorithm has been presented for a two-dimensional mesh network with C programming language. The efficiency of this algorithm compared via simulator tool ProcSimity with other continuous and non continuous allocation algorithms. Simulation results indicate improved Utilization Processor in the given algorithm.

Abstract: Prostaglandins are a group of 20-carbon fatty acids produced from arachidonic acid via the cyclooxygenase pathway in response to extrinsic stimuli (Smith 1989, 1992; Smith et al.,1991; Smith et al., 2011). Prostanoid biosynthesis (including classical prostaglandins PGD,PGE and PGF, as well as prostacyclins and thromboxanes) proceeds in three stages: (1) extrinsic stimuli-activated mobilization of esterified arachidonate from precursor lipids in the cell membrane through the action of lipases, (2) conversion of arachidonate to the prostaglandin endoperoxide (PGH2) mediated by PGH synthases, and (3) cell-specific isomerization or reduction of PGH2 by specific synthases (isomerases) or reductases to the major biologically active prostanoids PGD2, PGE2, PGF2α, prostacyclin (PGI2), or thromboxane A2 (TXA2; Figure1, modified from Smith, 1992; Smith et al., 2011). Prostaglandins are local hormones (i.e. autocoids; Smith 1989, 1992; Smith et al., 1991). Infused PGE and PGF derivatives fail to survive a single pass through the circulatory system. Their synthesis is not restricted to a central endocrine organ, but rather occurs in most organs, although not necessarily in all cell types. The plasma concentrations of these compounds, except in rare situations, are less than 10-9M, a concentration normally unable to elicit responses.
