Self-Similar Network Traffic : From Chaos and Fractals to Forecasting and QoS

It is well known nowadays, that packet network traffic has the self-similar nature [4], and conventional models, such as simple Markovian (memoryless) models, have faults. Moreover, the self-similar structure of the traffic leads to a number of undesirable effects like high buffer overflow rates, large delays and persistent periods of congestion. This paper presents the basic concept of the theory of self-similar teletraffic, its relationship with non-linear dynamics and fractals. The paper also studies the problem of providing QoS in the presence of self-similarity from the point of view the traffic prediction technique.
DENGAN METODE DISCRETE WAVELET TRANSFORM ( DWT ) DAN SUPPORT VECTOR MACHINE ( SVM )

Petrology is a field of geological science focused on the study of rock and its forming conditions. Petrography is a branch of petrology that explains detailed descriptions of rocks, based on mineral content and texture. Rocks are a collection of minerals that freeze. These minerals are generally referred to as rock-forming minerals. By identifying each of the minerals in the rock, using a microscope, classifications can be done. Characteristics of each type of rock can be distinguished from the percentage of minerals from the rock. Currently, petrographers use conventional method to examine the rock, using manual vision. This method is low in term of a accuracy and time efficiency. In this work, the authors designed a MATLAB-based software that can classify the types of rocks. The system input in the form of digital images of the rocks microscopically taken from a petrographic microscope, and furthermore was processed by the system. The first process is an extraction feature through Discrete Wavelet Transform (DWT). Next is the image classification process through the Support Vector Machine (SVM) method. From the results, highest accuracy obtained is 83.9506%.
EFFECT OF CHANNEL LENGTH VARIATION ON ANALOG AND RF PERFORMANCE OF JUNCTIONLESS DOUBLE GATE VERTICAL MOSFET

This paper investigates the effect of channel length (Lch) variation upon analogue and radio frequency (RF) performance of Junctionless Double Gate Vertical MOSFET (JLDGVM). The study has been performed under the fixed level of process parameters by considering the dependence of analogue and RF properties on the channel length. Furthermore, this paper aims to give a comprehensive insight on possible improvement in the performance of analogue and RF of the JLDGVM device. The structure and characteristics of the device are developed and extracted respectively via 2D TCAD simulation. The results show that both transconductance generation factor (TGF) and transconductance (gm) of the JLDGVM device are tremendously increased by 83% and 74% respectively as the scale of channel length is reduced from 12 nm to 9 nm. On the other hand, the unity gain cut-off frequency (fT) and the gain-band-width product (GBW) tremendously improved by ~93% and ~74% respectively as the channel length of the device is scaled from 12 nm to 9 nm.
OF PARALLEL HIGH PERFORMANCE GF ( 2 233 ) MULTIPLIERS

For many applications from the areas of cryptography and coding, finite field multiplication is the most resource and time consuming operation. We have designed and optimized four high performance parallel GF (2) multipliers for an FPGA realization and analyzed the time and area complexities. One of the multipliers uses a new hybrid structure to implement the Karatsuba algorithm. For increasing performance, we make excessive use of pipelining and efficient control techniques and use a modern state-of-the-art FPGA technology. As a result we have, to our knowledge, the first hardware realization of subquadratic arithmetic and currently the fastest and most efficient implementation of 233 bit finite field multipliers.
Causal Relationship between Gold Price and Sensex: A Study in Indian Context

Gold has been used around the world as an instrument for investment to hedge against inflation or in the form of jewellery. All these factors are the reason for hyping the demand for gold day by day. As per world gold council gold demand in India is about to rise 33% by 2020.The cumulative annual demand will be excess of 1,200 tonnes by 2020.Recently India has become the largest consumer of gold and price of gold is likely to breach Rs 32,000 mark in the next calendar year. There is an inverse relationship between gold price and dollar. In this paper, an attempt has been made to investigate the existence of unidirectional or bidirectional relationship between gold price and Sensex for the period of 10 years (2002-2012). The results of the analysis show that there is no causality between the gold price and Sensex. Gold Prices, Stock Market Return, BSE, Volatility, Co-integration.
STUDY OF LIPID PROFILE IN CORD BLOOD OF FULL TERM NEONATES OF NORMAL LABOUR

Background: Neonates of mothers having a family history of hypertension & coronary heart disease have a high risk of developing atherosclerosis in later life as they have increased blood lipids & cholesterol since birth. Therefore efforts are being made for screening for hyperlipidemia in the cord blood to screen the newborn who is at risk of developing atherosclerosis in later life so that necessary steps can be taken for its prevention at an early age. Material and methods: This work was undertaken to study lipid profile of cord blood of full-term pregnant women in normal labor. The parameters evaluated were serum triglyceride (TG), cholesterol (CHOL), high-density lipoprotein (HDL), lowdensity lipoprotein (LDL), very low-density lipoprotein. The family history of coronary artery disease and hypertension is recorded in each case. Results: The difference of mean for TG, CHOL, HDL, LDL, VLDL of cases is highly significant compared to control by ANOVA test. Serum TG, CHOL and VLDL were highly significant in all the three groups when compared to each other by post hoc test. Mean values were high for all parameters in female neonates but it was significantly high in CHOL and LDL levels. Conclusion: The genetic factors plays an important role in the transmission of hyperlipidemia and cord blood lipid estimation may provide a useful means to detect hyperlipidemia in high risk babies of full term pregnant women having family history of hypertension and coronary artery disease so that preventive measures could be taken early to retard the process of atherosclerosis.
Inhibition of Nelumbo nucifera Stamens-derived Kaempferol on Fc��RI-mediated GATA-1 Expression

The development of hematopoietic cells is regulated by the cooperated reaction of various transcriptional factors [1, 2]. GATA proteins, including GATA-1, GATA-2 and GATA-3, consist of highly preserved zinc finger DNA binding domains, and play crucial roles in immune systems. Among the GATA proteins, GATA-1 largely regulates hematopoietic cells fate, and is critical for the differentiation of erythroid cells, eosinophils, mast cells and basophils, as well as cell specific gene regulation [3− 6]. Mast cells and basophils are widely recognized as effector cells in IgE-dependent immediate allergic reaction. These proteins are characterized by expression of FcεRI, which is composed of one α, one β, and two γ subunits on the surface of effector cells in antigen/IgE-mediated hypersensitivity, the α chain is a specific factor of FcεRI and mostly stretches out into the extracellular area and directly binds to the Fc portion of the IgE with high affinity. The FcεRI α chain expression is modulated by multiple transcriptional factors such as GATA-1, PU-1 and Elf-1 in effector cells [7, 8]. Cross-binding of high affinity IgE receptor, FcεRI α chain, and inflammatory mediators involving histamine and β-hexosaminidase are released in immunologically activated mast cells and basophils, and result in allergic disorders involving asthma, atopic dermatitis, and allergic rhinitis [9−12]. Nelumbo nucifera Gaertn is a Nympaheceae family as perennial aquatic plant, commonly known as the lotus, and that is widely distributed throughout Eastern Asia. This plant has long been used in traditional medicines for the prevention of diarrhea, gastritis, insomnia, nervous prostration, and as a hemostatic [13−16]. N. nucifera stamens are flavonoid-rich, and have various physiological activities involving antioxidant, anti-inflammatory, and antidiabetic effects [17−19]. We previously showed that kaempferol suppressed expression of FcεRI via inhibition of extracellular regulated kinases (ERK)-1 activation [20, 21]. However, the regulation of GATA-1 by kaempferol in FcεRI-mediated allergic reactions has not been investiThe transcription factor, GATA-1, plays an important role in the FcεRI α chain expression in mast cells and basophils. This study was conducted to investigate the downregulation of the transcription factor GATA-1 by kaempferol isolated from Nelumbo nucifera stamens in FcεRI-mediated allergic reactions. Kaempferol inhibited FcεRI-mediated histamine release. Western blotting analysis and RT-PCR showed that the protein and mRNA expression of GATA-1 was suppressed by kaempferol in a dose-dependent manner. These results suggest that kaempferol may inactivate basophils by downregulating the FcεRI α chain expression via the inhibition of the GATA-1 expression.
Automatic Parallelisation in OO Languages with Balloons and Immutable Objects

Automatically detecting when it is safe to execute program expressions in parallel is hard. In this paper we take a step towards this ultimate goal by extending the original Almeida’s [1] balloons system with immutability and we utilise this information to figure out when the execution order of some expressions does not influence the result. Our type system for an imperative object-oriented language takes away the burden of parallelisation from the programmer and does not require the use of complex program analysis tools.
Phernome Based Node Tracking and Routing For Adhoc Networks

Wireless networking grows rapidly because of the human desires for mobility and for freedom from limitation, i.e., from physical connections to communication networks. Recent advances in wireless technology have equipped portable computers, such as notebook computers and personal digital assistants with wireless interfaces that allow networked communication even while a user is mobile. The main objective of this paper is to cope with weight. The proposed Route Tracking Protocol helps an existing system to cope with weight. As a concrete instantiation of such an existing system, we chose mobile ad-hoc networks (MANETs) running Dynamic Source Routing (DSR) and applied ANT to it.
A Comparative Study of the Impact of Himalayan Singing Bowls and Supine Silence on Stress Index and Heart Rate Variability

Introduction Sound vibrations have a profound impact on the body and the mind with evidence confirming reduced anxiety and increased wellbeing. The likely reason for driving the benefit is relaxation. The Himalayan Singing Bowls, used for therapeutic intervention to enhance the individual’s emotional & physical wellbeing, may facilitate faster and deeper relaxation as compared to simple, supine relaxation. Aim of the Study The study aimed to validate the hypothesis that short 20 minutes sessions to relax with the help of the Himalayan Singing Bowl (HSB) could provide better depth of relaxation as compared to Supine Silence (SS) based on the objective assessment of physiology parameters i.e. Stress Index & Heart Rate Variability (HRV). Methods Seven metal Himalayan singing bowls were used in a particular sequence learned from an expert teacher for 16 subjects. The SS group consisted of 17 subjects. The HRV data was measured by the Emwave Pro device and analyzed using Kubios HRV Premium software. The analysis compared key HRV parameters within and between the groups. Result Overall, as expected, both groups achieved relaxation as measured by changes in HRV parameters. However, further analysis confirmed a more consistent relaxation, as measured by a statistically significant reduction in stress index and an increase in HRV, for HSB group. The HSB group achieved more consistent depth of relaxation during each subsequent 5 minutes interval throughout the session as compared to SS group. Conclusion The study confirms that singing bowls sessions can be leveraged as a tool for inducing good quality relaxation response (increased parasympathetic tone, reduced stress) to facilitate healing and energy recovery in just 20 minutes and achieve significant health benefits. More comprehensive studies must be conducted to further evaluate the findings with more sample size, different methods of relaxation and varied demographics.
Evaluation of information leakage from cloud database service

The popularity of Database as a Service (DBaaS) for large scale web and mobile applications elevates data security risk and therefore providing a secure method to protect the data becomes a top priority. The aggregation of large number of databases in cloud, increases the risk of sensitive information to be compromised even for the encrypted data. The concept of cloud information leakage, resulted from any cross-referencing attacks in the pool of cloud-hosted databases, is defined and a mitigation method is proposed for NoSQL databases to leverage leakage-resilient data outsourcing in the presence of cloud internal and external adversaries. Sensitivity analysis of large-scale database plays a central role in the assessing information leakage. The problem with on-line analytical processing which seriously restricts usefulness is their excessive long response time. We proposed an Approximate Query Processing (AQP) technique to scale to any size databases in fast manner. The conducted extensive experiments on the different datasets, the results and theoretical analytics confirm the conduciveness of the proposed method.
Scenario based technique applied to photovoltaic sources uncertainty

There is an increasing need to forecast power generated by photovoltaic sources in day-ahead power system operation. The electrical energy generated by these renewable sources is an uncertain variable and depends on solar irradiance, which is out of control and depends on climate conditions. The stochastic programming based on various scenarios is an efficient way to deal with such uncertainties. In this research paper, the long term hourly recorded irradiance data in 15 past years are applied to generate the next day's irradiance scenarios. Irradiance determines the operating point of PV panel as well as the generated electrical power. Also, the scenario generation method based on autoregressive and moving average time series is proposed. For decreasing the number of scenarios, backward reduction based on Kantorovich distance is applied. The obtained results confirm the accuracy and ability of the proposed method in forecasting the relevant data. ling ideal wind turbines, ideal rotating devices or ideal wind farms either numerically or experimentally and gives the maximum possible power extractions; thus, any improvement to the performance of a system can be made by this method.
Cyberterrorism and its Dramatic Impact on Insurance and Security Companies

Cyberterrorism has come to be one of the most threatening forms of terrorism in 2019. In the face of the negative implications cyberattacks can have on affected firms and consumers, this article focuses on the flip side of the coin: I hypothesize that cyberattacks can produce abnormal positive returns for the stock prices of insurance and security companies. Heretofore practically ignored by most businesses, companies that specialize in insurance and security dealing with cyberterrorism are experiencing increased positive interest and attention. I conducted an event study analysis to investigate how the stock prices of insurance and security companies changed one day and one week after major cyberattacks on large firms. Such cyberattacks investigated range from the 2013 Yahoo attack to the globally destructive Petya Ransomware attack. Using the P-value as a measure of significance, I found that, on average, the companies realized a consistent, positive abnormal return in 11 of the 15 events one day after an attack. This evidence supported my hypothesis as investors understand that increased cyber activity results in increased cyber-awareness. Both insurance and security companies will likely increase premiums and experience higher quarterly revenues. Moreover, it was found that security companies experienced more positive, abnormal returns than insurance companies, as consumers gravitate towards security in hopes of greater protection.

Culturally Transformed Music Therapy in the Perinatal and Paediatric Neonatal Intensive Care Unit: An International Report

In July 2014, an international group of music therapists presented a Roundtable at the World Congress of Music Therapy to offer insight into music therapy practice with hospitalized newborn infants in 3 regions of the world: German speaking countries, Asia and South-East Asia, and the Americas and Oceania. While not a worldwide overview, this article provides a snapshot of early, emergent practice inclusive of some regions that are yet to be represented in the literature.
Surgical treatment of colon cancer

Most patients with colon cancer are surgically treated, with postoperative association of chemotherapy and possibly immunotherapy in advanced cases. Surgical treatment is chosen depending on the evolution stage, tumor topography and the existence of complications, colonic surgery being dictated by colonic vascularization. The radical character of the surgical intervention can be assured only in the early stages of the tumor. Colostomy is rarely necessary in patients with colon cancer. In the period of the last 5 years (2007-2011), 307 patients with colon cancer were operated in “Colentina” Surgical Clinic, radical intervention being possible only in 219 cases. 48 cases were emergency interventions for occlusion or perforation with peritonitis. Every time the mechanical preparation of the bowel was not possible, the intraoperative washout technique was used. Postoperative complications were met in 27 cases, being represented by bleeding (3 cases), peritoneal abscess (5 cases), anastomotic fistula (7 cases), abdominal wound infection (12 cases). In 5 cases the operation was done laparoscopically. Preoperative mortality was of 13 cases. Postoperative chemotherapy was done in the great majority of cases.
The impact of maternal obesity on vascular and metabolic function throughout pregnancy.

Maternal obesity increases the risk of numerous maternal and fetal complications of pregnancy. Women were recruited at booking for antenatal care. Each subject was examined in the first, Second and third trimester of pregnancy as well as twelve weeks post partum. Using non invasive techniques microvasular function was measured at each visit. Fasting bloods were taken. This assessment allowed us to observe microvascular function, inflammatory response, dislipidaemia and changes in fatty acid composition with advancing gestation and the degree of recovery in the post partum. By recruitment of women with varying body mass index (BMI) values we were able to examine the influence of maternal BMI on these responses to pregnancy.
Environmental influences on foliar anthocyanin production in Pinguicula planifolia (Lentibulariaceae)1

Abstract. In this study the environmental factors influencing foliar anthocyanin production in Pinguicula planifolia, a carnivorous plant whose leaves express varying colors of red and green, were examined. Seven P. planifolia sites within the Florida Panhandle were used. At each site, chlorophyll and anthocyanin content in leaves and environmental factors (light intensity, water depth, soil/water nutrients and pH, and vegetation height) were measured. At one of the sites, a light manipulation study (i.e., control, clipped, and caged) was conducted to test the effects of normal, heightened, and lowered solar radiation on red and green plants. Overall, foliar anthocyanin was influenced by environmental factors (i.e., light intensity as affected by water depth and vegetation height, vegetation cover, soil/water nutrient content) and the light manipulation study confirmed the role of light intensity on anthocyanin production. This study provides evidence that light intensity alone can effectively increase or decrease anthocyanin production in P. planifolia. Further work is needed to determine if anthocyanins may serve as a type of protective screening from ultraviolet radiation in this species.
Development of Unconventional T Cells Controlled by MicroRNA

Post-transcriptional gene regulation through microRNA (miRNA) has emerged as a major control mechanism of multiple biological processes, including development and function of T cells. T cells are vital components of the immune system, with conventional T cells playing a central role in adaptive immunity and unconventional T cells having additional functions reminiscent of both innate and adaptive immunity, such as involvement in stress responses and tissue homeostasis. Unconventional T cells encompass cells expressing semi-invariant T cell receptors (TCRs), such as invariant Natural Killer T (iNKT) and Mucosal-Associated Invariant T (MAIT) cells. Additionally, some T cells with diverse TCR repertoires, including γδT cells, intraepithelial lymphocytes (IEL) and regulatory T (Treg) cells, share some functional and/or developmental features with their semi-invariant unconventional counterparts. Unconventional T cells are particularly sensitive to disruption of miRNA function, both globally and on the individual miRNA level. Here, we review the role of miRNA in the development and function of unconventional T cells from an iNKT-centric point of view. The function of single miRNAs can provide important insights into shared and individual pathways for the formation of different unconventional T cell subsets.
In vitro and in vivo Virulence Potential of the Emergent Species of the Acinetobacter baumannii (Ab) Group

The increased use of molecular identification methods and mass spectrometry has revealed that Acinetobacter spp. of the A. baumannii (Ab) group other than A. baumannii are increasingly being recovered from human samples and may pose a health challenge if neglected. In this study 76 isolates of 5 species within the Ab group (A. baumannii n = 16, A. lactucae n = 12, A. nosocomialis n = 16, A. pittii n = 20, and A. seifertii n = 12), were compared in terms of antimicrobial susceptibility, carriage of intrinsic resistance genes, biofilm formation, and the ability to kill Caenorhabditis elegans in an infection assay. In agreement with previous studies, antimicrobial resistance was common among A. baumannii while all other species were generally more susceptible. Carriage of genes encoding different efflux pumps was frequent in all species and the presence of intrinsic class D β-lactamases was reported in A. baumannii, A. lactucae (heterotypic synonym of A. dijkshoorniae) and A. pittii but not in A. nosocomialis and A. seifertii. A. baumannii and A. nosocomialis presented weaker pathogenicity in our in vitro and in vivo models than A. seifertii, A. pittii and, especially, A. lactucae. Isolates from the former species showed decreased biofilm formation and required a longer time to kill C. elegans nematodes. These results suggest relevant differences in terms of antibiotic susceptibility patterns among the members of the Ab group as well as highlight a higher pathogenicity potential for the emerging species of the group in this particular model. Nevertheless, the impact of such potential in the human host still remains to be determined.
