Multi key algorithm for performance enhancement of video encryption

Video compression and security both need to be emphasized for reliable and fast communication. This paper proposes an algorithm which emphasize both compression and security through the combination of Embedded Zero Wavelet (EZW) and chaotic logistic map. In the first phase, video is encoded using decoupled 3D-DWT architecture and then compressed using EZW. The data obtained from EZW is given as input to the chaotic logistic map, which provides security. Chaotic logic map is used for providing security as it is simple and more sensitive towards the changes in the initial conditions. The time taken to provide security is efficiently reduced by chaotic logistic map algorithm. To provide a reliable security two keys are used at the transmitter and three keys are used at the receiver. The timing requirement of the chaotic logistic map algorithm is compared with the AES in the results section and found to be much better.
Phenotypic evaluation of scutellum-derived calluses in ‘Indica’ rice cultivars

By using amenable MS based medium containing 4 mg l-1 2,4-Dichlorophenoxyacetic acid (2,4-D), 0.4 mg l-1 benzyl-aminopurine (BAP), 30 g l-1 sucrose, 8 g l-1 Agar-agar, qualitative and quantitative traits of calluses initiated from four genetically and commercially valuable Northern Iranian rice cultivars including Hashemi, Hasani, Gerdeh, and Gharib were studied. Five seeds were placed in each Petri dish and three replicates of eight Petri dishes per replicate were incubated in a growth chamber at 25 ±2 °C in the dark and the averages for every replicate were employed in the analyses. Several important parameters related to callogenesis of the cultivars including rate of non-viable seeds, necrotic, scutellar, slow growing, and non-scutellar calluses, simultaneous callus induction from scutellar and non-scutellar tissues, seeds with appropriate callus, and root emergence were compared. Accordingly, calli of Gharib and Hashemi were highly responsive in callogenesis, while Gerdeh and Hasani produced dissatisfying calluses. Necrotic calluses, scutellar calli, and non-viable seeds were positively correlated with each other; although they were negatively correlated with non-scutellar calli, simultaneous scutellar and non-scutellar calli induction, and root emergence. The results of the present study are expected to be the first promising step to generate genetically manipulated Iranian indigenous rice cultivars.
Optimal phytoplankton cell size in an allometric model

The competitive ability of phytoplankton cells is simulated in a model chemostat in which cell size is considered to be an adaptive trait. Parameters describing nutrient uptake kinetics are constrained by empirically derived allometric rules. With a steady input of a single nutrient, the evolutionarily stable cell size is selected through competition among phytoplankton. We find that large cells may be favored when (1) phytoplankton growth is limited by the rate at which internally stored inorganic nutrients can be converted into biomass, and (2) maximum quotas increase with size faster than minimum quotas. Increased internal quotas then accelerate the rate of biomass production in large cells, despite their enhanced requirements for resources. The evolutionarily stable strategy is set by the allometric relationships for nutrient uptake kinetics and by metabolism.

Here, we report the genome sequence of a patient stool isolate from that outbreak, strain EDL932.
Novel Mucoadhesive Oral Patch Containing Diazepam

The oral patch of diazepam (DZ) was developed to achieve a rapid absorption of DZ for the emergency treatment of epileptic seizure or anxiety disorder. The patch was composed of the outer mucoadhesive Carbopol 934 region, central drug region, and Tegaderm backing film. DZ (3 mg) was dissolved in propylene glycol (PG) alone or PG containing oleic acid (OA) at 5.6% (w/w), and used as the drug region. The patches with and without OA were attached to the mucosa of cheek in rats. The patch with OA exhibited the plasma level of more than 200 ng/mL at 10 min after administration, then the plasma concentration decreased gradually. The patch without OA displayed a plasma level of less than 30 ng/mL during 40 min after administration. To the contrary, in the in vitro drug permeation using a cellulose membrane, the patch without OA showed a three times faster permeation rate than the patch with OA, suggesting that the direct action of OA to mucosa might be associated with absorption enhancement. It was demonstrated that the patch with OA showed a good adhesion to oral mucosa and worked efficiently for rapid absorption of DZ.
A Novel and Flexible Cloud Architecture for Data-Centric Applications

Software as a service or (SaaS) is a new software development and deployment paradigm over the cloud. It offers Information Technology services dynamically as “on-demand” basis over the internet. The related application data are stored in the large data centers managed by the Cloud Service Providers. Therefore the user need not to bother about the data storage or data management techniques and they can be able to access their applications from anywhere on the globe via a standard web browser. Many enterprises are facing a major research challenge due to the unavailability of generic cloud architecture for designing, developing and deploying of cloud services. In this paper flexible cloud architecture has been proposed, specifically for data centric applications which are suitable for heterogeneous types of applications. This paper also has aimed to establish the future research agendas related to design and management of data centric applications over the cloud infrastructure.

What Drives Student Loyalty in Universities: An Empirical Model from India

Student loyalty is one of the major goals of educational institutions. A loyal student population is a source of competitive advantage. The specific objective of this research was to develop an empirical model linking student loyalty to student satisfaction and student perception of the reputation of the institution. Based on the data collected from students with leading universities in India, a structural model was developed explaining 57.7% of the variance in the student loyalty. The student satisfaction was seen to be a major driver of student’s loyalty. The reputation of the institution also had a positive impact on student loyalty through the mediating variable student satisfaction. The research also validated a measurement model for student satisfaction and prioritized various dimensions of the satisfaction construct.
Analysis of cascaded multi-output-port converter for wireless plug-in Hybrid/On-Board EV chargers

This paper presents a new cascaded connection of multi-output-port converter for Plug-in Hybrid Electric and On-Board Electric Vehicles, which is suitable for dynamic wireless power transfer energy storage systems such as battery, ultra-capacitor, and load. In order to acquire the system power transfer integration between output ports, the central control stability is analyzed by phase shift function between converter ports. The theoretical calculation of the converter is explored describing the system model with a constant frequency under the different load conditions. The performance of the proposed converter is confirmed with experimental results using 8 inch air gap coreless transformer. The converter is tested at 120 V input and creates an output of 0-100 V and 0-50 V in each output port at a full power of 700 W.
Interactive Lenses for Visualization: An Extended Survey

The elegance of using virtual interactive lenses to provide alternative visual representations for selected regions of interest is highly valued, especially in the realm of visualization. Today, more than 50 lens techniques are known in the closer context of visualization, far more in related fields. In this paper, we extend our previous survey on interactive lenses for visualization. We propose a definition and a conceptual model of lenses as extensions of the classic visualization pipeline. An extensive review of the literature covers lens techniques for different types of data and different user tasks and also includes the technologies employed to display lenses and to interact with them. We introduce a taxonomy of lenses for visualization and illustrate its utility by dissecting in detail a multi‐touch lens for exploring large graph layouts. As a conclusion of our review, we identify challenges and unsolved problems to be addressed in future research.
FPGA based Digital Control with High-Resolution Synchronous DPWM and High-Speed Embedded A/D Converter

Digital control solutions become more attractive than analog controllers because they allow easy design of more complex control strategies, reconfigurability, high immunity to noise and low power consumption. However, as the control target and power stage of the converter are inherently analog, digital controllers require the addition of Analog-to-Digital (A/D) converters. This data conversion generates additional problems derived from time discretization and finite word length effects. Particularly, for applications with high switching frequency and tight output voltage regulation, the limited resolution of the Digital Pulse Width Modulator (DPWM) and the sampling frequency of the A/D converter are important issues. In this paper, a high-resolution synchronous DPWM and a high-speed A/D converter using FPGA resources are proposed and validated in order to obtain a cost-effective implementation.
Solution of economic load dispatch problems with valve-point effect using Novel TANAN's Algorithm

The Economic Load Dispatch (ELD) problems in power generation systems is to reduce the fuel cost by reducing the total cost for the generation of electric power. This paper presents an efficient Novel TANAN's Algorithm (NTA), for solving ELD Problem. [1] The main objective is to minimize the total fuel cost of the generating units having quadratic cost characteristics subjected to limits on generator true power output and including valve point loading effects. The NTA is a simple numerical random search approach based on a parabolic TANAN function. This paper presents an application of NTA to ELD for different IEEE standard test systems.
CHARACTERIZATION OF THE COMPANION μ HER

μ Her is a nearby quadruple system with a G-subgiant primary and several low-mass companions arranged in a 2+2 architecture. While the BC components have been well characterized, the Ab component has been detected astrometrically and with direct imaging but there has been some confusion over its nature, in particular, whether the companion is stellar or substellar. Using near-infrared spectroscopy, we are able to estimate the spectral type of the companion as an M4±1V star. In addition, we have measured the astrometry of the system for over a decade. We combined the astrometry with archival radial velocity measurements to compute an orbit of the system. From the combined orbit, we are able to compute the mass sum of the system. Using the estimated mass of the primary, we estimate the mass of the secondary as 0.32 M ⊙ , which agrees with the estimated spectral type. Our computed orbit is preliminary due to the incomplete orbital phase coverage, but it should be sufficient to predict ephemerides over the next decade.
Addressing multiple nodes in networked labs-on-chips without payload re-injection

On a droplet-based Labs-on-Chip (LoC) device, tiny volumes of fluids, so-called droplets, flow in channels of micrometer scale. The droplets contain chemical/biological samples that are processed by different modules on the LoC. In current solutions, an LoC is a single-purpose device that is designed for a specific application, which limits its flexibility. In order to realize a multi-purpose system, different modules are interconnected in a microfluidic network — yielding so-called Networked LoCs (NLoCs). In NLoCs, the droplets are routed to the desired modules by exploiting hydrodynamic forces. A well established topology for NLoCs are ring networks. However, the addressing schemes provided so far in the literature only allow to address multiple modules by re-injecting the droplet at the source every time, which is a very complex task and increases the risk of ruining the sample. In this work, we address this issue by revising the design of the network nodes, which include the modules. A novel configuration allows the droplet to undergo processing several times in cascade by different modules with a single injection. Simulating the trajectory of the droplets across the network confirmed the validity of our approach.
Control of the tissue inhibitor of metalloproteinases‐1 promoter in culture‐activated rat hepatic stellate cells: Regulation by activator protein‐1 DNA binding proteins

In the injured liver hepatic stellate cells (HSCs) undergo a dramatic phenotypic transformation known as “activation” in which they become myofibroblast‐like and express high levels of the tissue inhibitor of metalloproteinase 1 (TIMP‐1). HSC activation is accompanied by transactivation of the TIMP‐1 promoter. Truncation mutagenesis studies delineated a minimal active promoter consisting of nucleotides −102 to +60 relative to the major start site for transcription. Removal of an AP‐1 site located at nucleotides −93 to −87 caused almost a complete loss of promoter activity. Analysis of AP‐1 DNA binding activities during culture activation of HSCs initially indicated transient expression of proteins capable of forming a low mobility AP‐1 DNA binding complex (lm AP‐1). lm AP‐1 was maximally induced at 24 hours of culture and then fell to undetectable levels at 120 hours. Western blot studies showed that both c‐Fos and c‐Jun underwent similar transient inductions. These temporal changes in c‐Fos and c‐Jun activities were unexpected because TIMP‐1 mRNA expression is not detected in HSCs until culture day 3 to 5 and is thereafter sustained at a high level. Previous work in other cell lineages has established a key role for Pea3 binding proteins (Ets‐1) in AP‐1 mediated transactivation of the TIMP‐1 promoter. We show that HSCs express relatively low levels Ets‐1 and Ets‐2 and show that mutagenesis of the Pea3 DNA binding site in the TIMP‐1 promoter has less than a twofold effect on its activity in activated HSCs. Further analysis of AP‐1 DNA binding activities in 7‐ to 14‐day culture activated HSCs led to the discovery of high mobility AP‐1 complexes (hm AP‐1). hm AP‐1 DNA binding activities were sequence specific with respect to AP‐1 and absent from freshly isolated HSCs. Supershift EMSA and Western blot studies identified JunD, Fra2, and FosB as potential components of theHM AP‐1. Mutations of the AP‐1 site of the TIMP‐1 promoter that prevented formation of hm AP‐1 caused a 70% loss of activity in transfected activated HSCs. Taken together the data indicate that sustained upregulation of TIMP‐1 gene expression may be at least partially controlled by a novel AP‐1 dependent regulation of TIMP‐1 promoter activity.
TEMPERATURE-SPECIFIC OUTCOMES OF CYTOPLASMIC-NUCLEAR INTERACTIONS ON EGG-TO-ADULT DEVELOPMENT TIME IN SEED BEETLES

Abstract The integration of the mitochondrial and nuclear genomes coordinates cellular energy production and is fundamental to life among eukaryotes. Therefore, there is potential for strong selection to shape the interactions between the two genomes. Several studies have now demonstrated that epistatic interactions between cytoplasmic and nuclear genes for fitness can occur both at a “within” and “across” population level. Genotype-by-environment interactions are common for traits that are encoded by nuclear genes, but the effects of environmental heterogeneity on traits that are partly encoded by cytoplasmic genes have received little attention despite the fact that there are reasons to believe that phenotypic effects of cytoplasmic genetic variation may often be environment specific. Consequently, the importance of environmental heterogeneity to the outcomes of cyto-nuclear fitness interactions and to the maintenance of mitochondrial polymorphism is unclear. Here, we assess the influence of temperature on cyto-nuclear effects on egg-to-adult development time in seed beetles (Callosobruchus maculatus). We employed an “across-population” design, sourcing beetles from five distinct populations and using backcrossing to create orthogonal combinations of distinct introgression lines, fixed for their cytoplasmic and nuclear lineages. We then assayed development times at two different temperatures and found sizeable cyto-nuclear effects in general, as well as temperature- and block-specific cyto-nuclear effects. These results demonstrate that environmental factors such as temperature do exert selection on cytoplasmic genes by favoring specific cyto-nuclear genetic combinations, and are consistent with the suggestion that complex genotype-by-environment interactions may promote the maintenance of polymorphism in mitochondrial genes.
High-order EDA

In this paper, we investigate the usage of history information for estimation of distribution algorithm (EDA). In EDA, the distribution is estimated from a set of selected individuals and then the estimated distribution model is used to generate new individuals. It needs large population size to converge to the global optimum. A new algorithm, the high-order EDA, is proposed based on the idea of filter. By the usage of history information, it can converge to the global optimum with high probability even with small population size. Convergence properties are then discussed. We also show the application for constrained optimization problems.
A Plant Plasma Membrane H+-ATPase Expressed in Yeast Is Activated by Phosphorylation at Its Penultimate Residue and Binding of 14-3-3 Regulatory Proteins in the Absence of Fusicoccin*

The Nicotiana plumbaginifolia plasma membrane H+-ATPase isoform PMA2, equipped with a His6 tag, was expressed in Saccharomyces cerevisiae and purified. Unexpectedly, a fraction of the purified tagged PMA2 associated with the two yeast 14-3-3 regulatory proteins, BMH1 and BMH2. This complex was formed in vivo without treatment with fusicoccin, a fungal toxin known to stabilize the equivalent complex in plants. When gel filtration chromatography was used to separate the free ATPase from the 14-3-3·H+-ATPase complex, the complexed ATPase was twice as active as the free form. Trypsin treatment of the complex released a smaller complex, composed of a 14-3-3 dimer and a fragment from the PMA2 C-terminal region. The latter was identified by Edman degradation and mass spectrometry as the PMA2 C-terminal 57 residues, whose penultimate residue (Thr-955) was phosphorylated. In vitrodephosphorylation of this C-terminal fragment prevented binding of 14-3-3 proteins, even in the presence of fusicoccin. Mutation of Thr-955 to alanine, aspartate, or a stop codon prevented PMA2 from complementing the yeast H+-ATPase. These mutations were also introduced in an activated PMA2 mutant (Gln-14 → Asp) characterized by a higher H+ pumping activity. Each mutation directly modifying Thr-955 prevented 14-3-3 binding, decreased ATPase specific activity, and reduced yeast growth. We conclude that the phosphorylation of Thr-955 is required for 14-3-3 binding and that formation of the complex activates the enzyme.
Employing a very sparse matrix converter for improved dynamics of grid-connected variable speed small wind turbines

The amount of energy obtained from a wind turbine depends not only on the wind regime but also on the control technique used to govern the turbine. When wind speed changes, the turbine moves away from its optimal tip speed ratio until maximum power point tracking forces the turbine to operate at its optimal speed. For rapid wind speed changes, the maximum power point tracking controller can take longer than the necessary time to return the turbine to its maximum power coefficient which reduces the energy harvest, especially in gusty conditions. Proposed in this paper is a motoring-generating control technique for grid-connected small wind turbines in order to accelerate the turbine to its optimal operating speed in the case of increasing wind speed. In the case of decreasing wind speed, the turbine decelerates by loading the generator at its maximum torque. The generator torque is controlled through the backward bidirectional very sparse matrix converter where the grid is connected to the rectifier stage and the generator is connected to the inverter stage. The generator torque is regulated by controlling the generator current based on the principle of field oriented control where a decoupling between the field and torque current components is achieved. The direct axis current is set to zero while the quadrature axis current is used to control the generator torque and speed. Then the generator reference voltage and the converter switching signals are synthesized using the principle of space vector modulation. In order to show the feasibility of the proposed control technique, a 5.7kW grid-connected variable speed wind turbine is simulated using Matlab/Simulink.
Reviewing the Life Cycle: Women’s Lives in the Light of Social Changes

Our chapter involves both a theoretical revision and a set of reflections that aim to analyse and redefine the significance of the final stages of the female life cycle, which has been revolutionised by two major set of circumstances: the increase in life expectation and the social changes that have taken place in the western world during the second half of the 20th century. In this regard, our reflections deal with the consequences that this spectacular prolongation of life has had for women. We also discuss the new significance that living into old age may have for women who will reach old age during the early decades of this century and who are the beneficiaries of the important social changes of the second half of the past century.
